    Description: [0001] The invention relates to a circuit for the manufacture of circuit boards according to claims 1,2, 3, 6, 8, 11, 12, 14, 15, 17, 18 and 19.
    Formwork clamps are now used in the creation of formwork for foundations made of concrete, for ring formwork, coatings, parapets, formwork on existing walls and gable formwork on concrete walls.
    When working at heights over 3 m from the ground, e.g. in the manufacture of balcony balustrades, ring formwork, walls with large-scale formwork and joists must be created compulsory guardrail. For this purpose, from CH 709 836 B1 a protective railing device has become known, which is arranged on a formwork clamp. On the formwork clamp a square tube is welded to one of the two jaws, in which a railing post can be inserted as part of a fall protection and is held securely there. As a result, the formwork clamp can be used in addition to the holder of a railing post. This formwork clamp can also be easily placed on an existing wall and used there only as a railing post holder. The disadvantage is that with the known formwork clamps railing posts on faces of substructures, Baikon, ceilings and parapets with this clamp can not be attached.
    After completion of balcony floors, floors in stairwells and along steps on stairs and industrial ceilings guard railing must also be arranged in the shell. For this purpose, either in the front sides of the balcony slabs or in the ceilings and stairs sleeves or corresponding brackets for consoles or sleeves for protection railing can be embedded. This is on the one hand costly and time consuming or forgot. On the other hand, stairs are delivered as prefabricated elements and therefore usually without such mounting options for railings.
    Even in the creation of walls with large-scale formwork, a railing must be created for concreting the wall above or to the side of the large-scale formwork. For this purpose, special counter balustrades have been built. This counter railing or its fasteners are specially designed for each formwork panel type on the market. These fasteners are on the one hand expensive and on the other hand hinder the work on the wall to be created. Also, their assembly is time consuming and complicated.
    An object of the present invention is to provide a formwork clamp, which can be arranged regardless of the location of the attachment point in a simple manner and stretched and possibly even secured. Another object of the invention is to provide a formwork clamp to which railing posts can be attached to the formwork ferrule independently of the mounting position (horizontal / vertical / oblique). Another object of the present invention is to provide a formwork clamp in which mechanical elements such as the spindle for adjusting the jaws are arranged so that they can not be contaminated by concrete, concrete water and additives of the concrete during concreting.
    Another object of the present invention is now to provide a multi-functional formwork clamp as a fastening device for railing on exposed faces of Baikon, parapets, stairs and Stairway intermediate floors and other exposed faces of ceilings an anchoring means, which provides a secure temporary hold for railing posts and thus for the creation of guardrails allows.
    Another object of the present invention is to provide a formwork clamp that can be securely attached to horizontal and vertical walls, cavity walls and large-scale frame formwork and can be used as an anchor for railing posts. Another object of the invention is the provision of retaining means on which the formwork ferrule can be easily carried and held at the respective sites of use until clamping is achieved by means of the jaws. Another object of the invention is to provide a formwork ferrule for use as a railing post mount and / or directly as a railing post on bulkhead formwork for creating counter railings.
    This Aufqabe is achieved by a Schalunqszwinqe qemäss the features of claims 1, 2, 3, 6, 8, 11, 12, 14, 15, 17, 18 and 19.
    Advantageous embodiments of the formwork clamp are described in the dependent claims.
    With the inventive formwork clamp not only formwork can be created and maintained in a previously known type, but the formwork clamp allows to clamp the shuttering clamp on end faces of ceilings or floors, parapets or projections and on large-scale formwork and at this a baluster insert and hold there or serve as a railing post. At the same time allow in an advantageous embodiment of the formwork clamp on both sides of the spindle mounted hand cranks to fasten the formwork clamp from the top of a balcony plate and clamp or do this from the bottom, i. from the site that is safe and / or more accessible. The arrangement of the spindle with which one or both jaws of the formwork clamp can be moved is within a protected space, e.g. a U-profile protected from contamination. At the same time, grease applied to the spindle can not reach the surface of substructures. With two unequal length handles on the crank (s), the torque acting on the spindle can be adjusted by means of a rod made of wood, steel or e.g. a hammer handle increases and thereby the clamping force of the ferrule can be improved. Cranks mounted on both sides of the spindle allow the formwork clamp to be secured so that the overhanging longer portion of the guide rail does not interfere with concreting or when used as a handrail stop. For example, in this way, the formwork clamp to a formwork or gable formwork are fixed so that the protruding long part outside the movable jaw is directed away from the wall to the outside and so does not project over the surfaces to be processed during concreting and also as a scaffold board carrier serves. Furthermore, the double-formed crank simplifies the handling of the formwork clamp essentially in each type of use.
    By using tubular profiles for the jaws instead of the previously used L-shaped profiles, the jaws can be used directly as guide sleeves for railing posts. The same applies to the profiles for the guide rail. If this is constructed from a tubular profile, for example a rectangular profile, then a railing post can be inserted and held from both sides. The arrangement of the guide spindle for the jaws within a U-shaped or egg-shaped profile, this is protected against mechanical damage and also when pouring the liquid concrete from contamination by concrete water and concrete additives.
    By guide sleeves with or without thread between the ends of the paired profiles for the individual jaws, be it from L-shaped profiles or tubular profiles, the formwork clamp can be attached to the stiffening elements or at least one of the stiffening elements of large-scale formwork and used as anchor for counter-railings. A formwork clamp, which is attached to a large-scale formwork, makes it possible to attach the counter railing at a distance to the side and to the formwork and thus to create space when casting the wall and also in prefabricated hollow walls for the concrete bucket. Furthermore, on the upper jaw, a board can be placed horizontally or inclined to the large-area formwork to prevent that during the filling of the concrete this falls outside the formwork panel down and further to prevent the worker does not crash when the Concrete bucket can not be held exactly above the opening between the two formwork panels. Such spaced fixed to the formwork balustrade no longer need to be arranged inclined as in the prior art, since their distance from the formwork panel is sufficiently large. However, if necessary, a railing can be used obliquely with the sleeves on the jaws of the formwork clamp. By attaching or forming previously unknown handles on the guide rail of the formwork clamp, this can be very easy to carry, handle and temporarily hold during attachment to an attachment point. The holding of the formwork clamp can be done thanks to the handles from all directions and it is the risk of trapping a hand between the formwork clamp and the sub-construction or the shuttering panels safely avoided.
    All the individual features in the present invention can be used on ferrules individually or in combination with each other.
    In a further advantageous embodiment of the formwork clamp, the guide rail is configured like a ladder, that is, two parallel juxtaposed profiles are connected by at least one web. This has the advantage that the formwork clamp can be optimally maintained, namely on the rear profile and on the other hand, between the ladder rungs, when the formwork clamp serves as a holder for railing posts or even as a railing post, inserted a toeboard or more than one Absperrbrett and kept. The universally usable formwork clamp can therefore serve directly as a railing post holder when it is attached to a floor or ceiling plate with the jaws. If their height is insufficient, a railing post can be additionally used in the guide rail. Another advantage of this formwork clamp is that the stiffness is substantially increased by the ladder-like design of the guide rail and thus after clamping the voltage is maintained. In particular, this embodiment of the formwork clamp is extremely well suited to be mounted on large-scale formwork and prefabricated hollow walls or hung and serve as a railing post holder or as a railing post.

    In the figures, reference numeral 1 designates a formwork clamp. This comprises a in the example according to FIG. 1 a U-shaped guide rail 3, at the ends bearing blocks 5 are arranged for the storage of a spindle 7. In Fig. 1 b, the guide rail 3 is closed except for a slot 33 for engagement with the spindle 7. At both ends of the spindle 7, which extend beyond the bearing blocks 5, crank handles 9 are held against rotation. The hand cranks 9, as shown in the example, each have a long handle 11 and a short handle 13. Of course, only at one end of the spindle a crank 9 could be attached and the hand crank 9 could also be configured only with the long handle 11 and / or a ring. The hand crank 9 with a long handle 11 and a short handle 13 and / or a ring or strap instead of a handle makes it possible, after the clamp 1 by turning by hand on one of the crank handles 9 at the attachment point to increase the necessary tension thereby in that a rod or a handle of a tool is passed transversely to the spindle 7 and thus the lever for the tightening torque on the spindle 7 can be increased. In addition to a hand crank 9 with one or two handles 11, 13, a polygonal head 39, e.g. a square or hexagon, be attached, which serves to turn the spindle very quickly with an on-site drill anyway existing with a corresponding four- or hexagonal nut. This can save a lot of time when the jaw distance must be adjusted.
    The various versions of hand cranks 9 are referred to collectively as cranks.
    The spindle 7 is protected in the U-shaped open (Fig. 1a) or partially open C-shaped guide rail 3 between the two legs. The spindle 7 is characterized on the one hand against mechanical damage of objects that fall on the guide rail 3 protected and, if the ferrule is used to hold Schalplatten, the spindle 7 is also protected against concrete water splashes and solids from the concrete.
    On the spindle 7 two mutually parallel jaws 17 and 19 are arranged. At least one of the two jaws 17, 19 is in engagement with the spindle 7, that is, the spindle 7 penetrates the jaw 17, on which a threaded bore 21 is formed. The threaded hole 21 is embedded in a guide member 23 to which the preferably constructed of two parallel profile elements 25 jaws 17, 19 are attached. The profile elements 25 are L-shaped in a first embodiment, wherein the foot part as a contact surface on a
    Formwork or vertical use of formwork clamp 1 comes into contact with a substructure. The jaw 17 is configured such that it is displaceable along the guide rail 3 with little play and perpendicular to the guide rail 1. For this purpose, the rear end of the jaw 17 wraps around the guide rail 3. Side and rear of the jaw 17 sliding plates 27 are arranged for this purpose, which include the guide rail 3 at the back and play without play.
    In FIGS. 2 to 5 it can be seen that on the back of the guide rail 3, a further guide tube 31 is attached or formed. The guide tube 31 advantageously extends over the entire length of the guide rail 3, so that both ends of the ground posts are hineinschiebbar.
    Furthermore, the two jaws 17 and 19 and their connecting elements extend beyond this guide tube 31 and wrap around it. As a result, the forces which act on the clamping jaws 17, 19 are supported over a distance at least twice as long as was previously possible without a guide tube 31. In other words, by this additional guide tube 31, a higher accuracy of the parallelism of the two jaws 17, 19 can be achieved. The additional guide tube 31 makes it possible, when using the ferrule 1 at the edge of a balcony or roof projection or a landing or even on stairs or lift openings with this ferrule a railing post is inserted and can be securely held (Fig. 7a, 7b). As a result, complicated, time-consuming and therefore expensive constructions for the construction of the mandatory barrier can be created. In addition to the better connection of the clamping jaws 17, 19 to the guide rail 3, the latter is substantially stiffened by the second guide tube 31, so that the clamping jaws 17, 19 do not lose their parallelism even under heavy load. The fastening of the ferrule 1, for example, on a balcony floor, can be done easily from the underlying balcony (Fig. 7a), since the lower end of the ferrule 1 is the longer and is easily accessible from below and also can be operated safely.
    In a further advantageous embodiment of the formwork clamp 1, the two jaws 17 and 19 are made of round or rectangular cross-sectionally shaped tubes. This has the advantage that the two jaws 17 and 19 are directly usable as sleeves for railing posts. So there is no need to attach additional elements for the inclusion of railing posts on the jaws 17,19. In addition, 35 holes can be inserted into the existing of round or rectangular tubes jaws, which serve on the one hand for passing nails for fixing shuttering panels and on the other hand as a stopper and / or fuse for railing posts used. As a stopper can be attached to the tubes 29, 31, a constriction by denting. Further holes 35 may be provided on the side surfaces of the jaws to form a stop for railing posts. Similarly, the guide rail 3 may be formed as a profile tube, that in the visible from the front in Fig. 8 area the spindle 7 is guided protected and in the rear area a railing post in the interior 37 can be inserted. By adding a rectangular tube behind the C or U-shaped rail for the spindle 7 results in a broadening of the guide rail 3, resulting in a substantial stiffening of the latter and consequently higher clamping forces can be applied by the jaws 17,19 in the attachment , In addition, the operation of the hand cranks 9 is not hindered, since an inserted into the second guide tube 31 railing post 57 does not prevent the rotation.
    Formed from hollow profile, round or Reckteckrohren jaws 17,19 and the guide rail 3 have over the known designs a much higher strength and consequently a higher accuracy of the parallelism of the jaws 17,19 when holding together and clamping of shuttering panels.
    It can be seen from FIGS. 6a and 6b that the section of the guide rail 3 projecting beyond the clamping jaw 17 can be arranged either over the floor on the partial component or advantageously outside the outer wall of the partial component (FIG. 6b). 7a and 7b show the use of the formwork clamp 1 Baikon or roof projections, etc. In Fig. 7b the protruding beyond the jaw 17 end of the guide rail 3 is above the ceiling, that is, the formwork clamp 1 can from above on the Ceiling to be mounted upright. If this is not possible or not desired for whatever reason, then the formwork clamp 1 according to FIG. 7a can also be fastened from below, for example from an underlying balcony. As a result, only the hand crank 9 protrudes above the clamping jaw 19. The formwork clamp 1 can thus be easily fixed from above, although their protruding longer part of the guide rail 3 projects downwards.
    8 to 13 are at the ends of the jaws 17,19 the two jaws 17,19 connecting guide elements 41,43 used. The guide elements 41,43 may be, for example, short sections of profile tubes, as used for the jaws 17,19, or below a nut, as shown in Fig. 11 below. The guide elements 41,43 serve to accommodate a securing pin 45, as shown in Fig. 14. In an advantageous embodiment of the securing mandrel 45 is provided with a thread or threaded portions, which in the threaded nut (guide member 43) can be screwed. As an alternative to a securing mandrel 45, which is screwed in, a threaded rod can also be used, on which a conventional (wing) nut can be screwed on at the top and bottom. This embodiment of the formwork clamp 1 serves to attach the formwork clamp 1 to a large-area formwork 47 in order to be able to use a railing post 57 for a counter railing therein. The attachment of the clamping jaws 17, 19 on the large-area formwork takes place on the stiffening elements 49, on which holes are already formed at intervals. The assembly is carried out in a simple manner by the formwork clamp 1 with the two jaws 17,19 clamped to a single or two parallel duri fenden stiffening elements and then secured by pushing a locking pin 45. In this embodiment or use of the formwork clamp 1 shows again optimally that the clamping of the formwork clamp is possible both from below or above, since at both ends hand cranks 9 or similar means such as a ring or a polygon are formed. On the upper jaw 19, if desired, directly a scaffolding board 51 are placed so that the worker is not in danger of kicking his foot next to the formwork. Of course, the formwork clamp 1 can also be attached only to a stiffening element 49.
    In a further advantageous embodiment of the formwork clamp 1 according to FIGS. 15 and 15a, on the upper, i. the fixed-mounted jaw 19 a hook 58 may be attached, which is part of a scaffold board holder 61. The scaffold board holder 61 further comprises a tube 59, the lower end of which can be inserted from above into the upper clamping jaw 19 or into the guide rail 3. The tube 59 further serves to anchor a railing post 57.
    On a board carrier that connects the tube 59 with a hook 58, a scaffolding board 63 can hang up on which one hand can stand and on the other hand, liquid concrete 65, which is emptied from a transport bin 67 between the large-area formworks 47 or outside the shuttering panel falls back to these. Preferably, the oblique position of the board support 60 is dimensioned so that the scaffolding board 63 is inclined to the formwork plate 47. It can also be clearly seen in FIG. 15 that the railing post 57, which is held in place on the formwork clamp 1, lies at a comparatively large distance from the large-area formwork 47 and thereby the transport receptacle 67 for concrete can not come into contact with the railing post 57 ,
    In order to simplify the handling of the formwork clamp 1, 17.19 handles 53 can be attached in the region of the rear ends of the two jaws. These may have the shape of U-shaped brackets, which are fastened to the guide rail 3. Additionally or alternatively, by one or more recesses 55 on the guide rail 3, the possibility can be created to take this approximately in the center of gravity. The handle 53 could also extend parallel to the guide rail 3 on its rear side (see Fig. 16).
    In a further advantageous embodiment of the formwork clamp whose guide rail 3, that is, the base member along which at least one of the two jaws 17,19 is slidably mounted, comprises two substantially parallel profile elements 3a and 3b. The profile element 3a receives the spindle 7 and the profile element 3b is preferably designed as a square tube. Alternatively, another cross-sectional shape of a hollow profile element 3b would be possible. The two profile elements 3a and 3b are spaced and are interconnected by webs. Depending on the length of the guide rail 3, a plurality of webs may be provided. Advantageously, the mutual distance of the webs 69 and their length is selected such that in the space between two webs 69 and laterally bounded by the profile elements 3a and 3b wooden slats, such as railings are used, can be inserted. If such a formwork clamp 1 is now attached to a balcony slab, to a free floor or ceiling slab or, in particular, to a large-area formwork 47, the section of the guide rail 3 lying above the upper jaw 17 can either be used directly as a railing or as a railing receiver is inserted into the top of the profile element 3b deflected post. Preferably, formwork clamps 1, which are mainly used as a railing post, provided with a length of the guide rail, which is at least one meter or more. Of course, such formwork clamps 1 can be used for all other applications, such as the creation of formwork for concrete foundations, ring formwork, coatings, beams, parapets, formwork on existing walls and gable formwork on concrete walls without any disadvantages compared to conventional formwork clamps 1. Like already described, can also be used on the formwork clamps according to FIGS. 17 and 18 securing mandrels 45 to secure the formwork clamp 1 on the large-area formwork 47, that is not only clamp the formwork clamp 1, but at the existing holes in the Stiffening elements 49 of the large-area shuttering 47 to keep unsolvable. On the other hand, with a very long guide rail 3, due to its high rigidity, a scaffold board can again be placed when the formwork clamp 1 is fastened to the crown of one wall or two shuttering panels.
    To prevent accumulation of concrete water or additives in the interior of the jaws 17,19 holes 57 are formed at the ends. Additional holes 59 may be provided on the jaws 17,19, through which nails can be driven into the formwork plates held by the jaws 17,19.
