    Technical area
    The present invention relates to a wall formwork system and a method for producing a wall section with a Isolierschalung. Such a wall formwork system or method is used in the field of civil engineering, for example, in basements to provide a concrete wall section with a perimeter insulation or the like.
    State of the art
    When producing, for example, a basement floor in a conventional construction, a wall formwork is placed in the area of the floor slab. This consists of an inner formwork and an outer formwork, which are arranged at a distance from each other and are connected to formwork anchors. Between the inner and outer formwork reinforcements or anchors are introduced, which are cast with the poured into the wall formwork concrete.
    After the concrete has hardened, the corresponding wall section is turned off, and then an insulating layer, for example. A Perimeterdämmung applied to the wall outside, in particular glued. As the outermost layer, for example, a plastic film is provided on the insulating layer to prevent the penetration of moisture and mechanical effects by the soil on the insulation.
    However, this conventional approach has the disadvantage that the potting of the concrete within the wall formwork as well as the application of the insulating layer must be performed separately from each other, so that a relatively long time is required for the preparation of the wall portion. In particular, the concrete must first harden in order to be able to subsequently shell out the wall section. Only 2/23 2 after stripping the wall section, the
    Insulating layer can be applied.
    As a prior art document US 6,314,694 Bl relates to a one-sided insulated formwork, which is used in the construction of walls of concrete, for example. In one embodiment of this document, a removable wall panel is shown attached to a connector of an anchor with a screw. The anchor in turn is connected to an insulating panel. However, the anchor remains after removing the wall formwork within the hardened wall. A fundamentally similar procedure is taught by CA 3,265,135 A1.
    Another prior art EP 2 058 446 A1 is known. According to this document, a first panel is provided, which consists of an insulating material, wherein an inner side of the first panel faces the interior of the building, and an outer side of the first panel faces an outer side of the building. Further, a second panel (for example, a plywood board) is provided.
    A first connector of an armature is connected to the first panel, and a second connector of the armature is connected to the second panel, for example, by means of a mechanical connection. Concrete is then filled in an intermediate section provided between the first and second panels. While the second panel (plywood panel) can be removed, the first panel remains fixed by means of the potted in the concrete wall anchor.
    Subject of the invention
    The present invention has been carried out to provide a wall formwork system and a method for producing a wall section with an insulation form, which can shorten the manufacturing time, reduce the total cost and reduce the manufacturing cost.
    The present invention provides for this a wall formwork system according to claim 1, a method for producing a wall section with an insulating formwork according to claim 8 and a use of the wall formwork system according to claim 12 ready.
    The core idea of the present invention is to combine the method steps for producing the concrete wall section and the application of the insulating formwork. For this purpose, instead of a shuttering wall, the Isolierschalung be provided, so that then the area between a first, eg. Conventional formwork wall and the Isolierschalung can be filled with concrete.
    The wall formwork system according to the invention therefore preferably comprises vertical system support rails, a reusable anchor rod and an anchor nut for releasably receiving the anchor rod, which can be attached to one of the system support rails. Furthermore, the wall formwork system comprises a holding means, which can be attached to a system support rail, for holding insulating panels on a side surface of the system support rails.
    The wall formwork system according to the invention has the advantage that all elements - with the exception of the insulating panels - are reusable, so for example, can flow into the rental business of a company. Furthermore, the basic method steps for producing an insulated wall section, that is to say producing the (concrete) wall and insulating this wall, can to a certain extent be combined into one method step. The insulating panels used for the insulation take on the task of a formwork wall, so that only a conventional shuttering wall 4/23 4 must be provided for the preparation of the wall section. As a result, the number of components necessary for the production of an insulated wall section is reduced, which ultimately also leads to a reduction of the manufacturing costs.
    Primarily, the present invention is directed to the formwork wall formed by insulating panels being an outer wall of the wall section. However, it is basically also conceivable that the insulating panels are attached to an inner wall of the wall section. Furthermore, in a further aspect of the present invention, as "first shuttering wall " Also meant to be one which is composed of a plurality of insulating panels, so that a both inside and outside insulated wall section is made.
    By the term "vertical system support rail " are meant components that are usually placed vertically in use, usually. Thus, the term "vertical system support rail " For the purposes of this application, also in use obliquely oriented system support rails, or partially branching system support rails.
    According to a preferred embodiment, the system support rails comprise longitudinally spaced openings. In this way, a grid is provided, via which other components can be connected to the system support rails, such as the anchor nut. In this way, the wall formwork system according to the invention can be adapted on site to the respective conditions.
    According to a further embodiment, the wall formwork system according to the invention is characterized in that the wall formwork system has a foot plate with a position pin, with which the system support rails can be connected to a bottom plate. In this way a 5/23 5 relatively quick and easy installation of the system support rails is possible.
    Furthermore, the anchor nut can have an opening on one
    Have wing element. The armature nut is, for example, supported relative to a system support rail via the wing element, and can be connected to the system support rail by a connecting element guided through the opening.
    In a further preferred embodiment, at least one cross rail is attached to the system support rails, which connects the system support rails together and thus enables stable support of the system support rails.
    According to a further embodiment, the holding means for holding insulating panels of a side surface of the system support rails has a profile, which profile is provided with at least one opening. In this way, the holding means can be connected to a guided through the opening of the profile connecting element with a system support rail.
    Further, the holding means may comprise a holding plate with a socket, through which socket a connecting means, such as a nail, can be performed. Thus, in a concrete application, the retaining plate will rest on an upper surface of an insulating panel, a connecting means, such as a nail or the like, may be driven through the sleeve and engaged with the insulating panel. In this way, the Isolierpaneel can be securely held on a side surface of the system support rails, at the same time the solubility of the holding means is ensured by the Isolierpaneelen after completion of the wall portion. By providing the retainer with a retainer plate and a bushing attached thereto, a worker can relatively easily fasten a 6/23 6 when fixing the insulating panels
    Incorporate connecting means, which further accelerates the procedure. The same applies to the possibility of releasing the holding means again from the insulating panel.
    The present invention is further directed to a method for producing a wall section with an insulating shutter, which method comprises the following steps:
    Providing a first formwork wall, providing a wall formwork section at a distance from the first formwork wall, the wall formwork system preferably comprising vertical system support rails, providing insulation panels along the system support rails and retaining the insulation panels with a retaining means on a side surface of the system support rails, and connecting the first formwork wall and the wall formwork system by at least one anchor rod, which preferably engages an anchor nut mounted on one of the preferably vertical system support rails of the wall formwork system.
    According to a preferred embodiment, the holding means partially receives a connecting means which engages on one and / or in an insulating panel. In this way, a connection between the wall formwork system and the insulating panels can be made relatively easily and quickly, which can be solved again after completion of the wall section.
    Further, an insulating panel may be pierced to guide the anchor rod through the insulating panel. In this way it is possible to build in the first place the wall formwork system with the insulating panels, and then to establish a connection with the first formwork wall. This makes it possible to react quite flexibly to the local conditions. 7/23 7
    According to a further embodiment, the anchor nut is aligned with one of the system support rails of the wall formwork system, and then connected to an anchor rod connected to the first wall formwork.

    Hereinafter, a preferred embodiment of the present invention will be described in detail. Individual modifications mentioned in this context may be combined to form new embodiments.
    Fig. 1 is a side view of a structure for producing a wall portion. On a base plate B, a first shuttering wall 100 is provided, which is a conventional formwork wall in the present illustration. This serves to support the trainee wall section with respect to an inside of the building. At a certain distance from the first formwork wall 100, a wall formwork system according to the present invention is provided.
    This wall formwork system comprises a plurality of vertical system support rails, which are interconnected by means of a horizontally arranged cross rail 60. Support brackets 12, 13, which in the present embodiment act on a common support element 14 and support the wall formwork system with respect to the later outer side of the wall section, are attached to holding heads 50, 51, which are mounted on at least one system support rail 10.
    In the present embodiment, in this case the system support rails 10 are anchored in pairs by means of a base plate 20 with respect to the bottom plate B and aligned. Since the wall formwork system in the present embodiment has more than two system support rails, it is sufficient to anchor at least one, but preferably at least two system support rail pairs with the foot plate 20 with respect to the bottom plate B.
    The foot plate 20 is shown in detail in Figures 2a and 2b. It comprises a position pin 21, which can penetrate into a bore introduced into the bottom plate B, and a support portion 22, which rests on one side of the bottom plate B. Starting from the support section 22, two connecting sections 23 extend with openings 24. The connecting sections 23 can, as shown in Fig. 2a, penetrate into the vertical system support rails 10. Through the openings 24 of the base plate 20 and the openings 11 'of the system support rails 10, a 9/23 9
    Connecting element are guided, and connect the base plate 20 with the respective system support rail 10.
    The tube 25 receives the position pin 21 in sections, at the end of a support plate 26 is fixed, in particular welded. Narrow sides of this support plate 26 can be brought into contact with side surfaces of the respective system support rail 10 to bring the respective system support rail 10 with the base plate 20 in abutment (see Fig. 2a). Furthermore, it is ensured by the mobility of the unit of position pin 21 and support plate 26 within the tube 25 that the support plate 26 along the system support rails 10 is displaceable. The position pin 21 could be locked relative to the tube 25.
    In the intermediate space provided between the system support rail pair, the gap shown in FIGS. 3a and 3b anchor nut 30 shown in detail are introduced. The anchor nut 30 includes a threaded portion 31 having an internal thread for connection to an anchor rod 110. In the present embodiment, on both sides of the threaded portion 31 support plates 32 are provided which each have transverse projections 32 '. By means of the transverse projections 32 'prevents the anchor nut 30 is inserted too far between the system support rails 10. Furthermore, a support against the anchor rod 110 is provided.
    Starting from the respective support plate 32, wing elements 33, which are each provided with longitudinal openings 34, extend. Through these longitudinal openings 34, a connecting means can be guided, which also penetrates through one of the openings 11 of a system support rail 10 and in this way establishes a connection between the respective system support rail 10 and the armature nut 30. 10/23 10
    As shown in Fig.l, a plurality of anchor nuts 30 can be aligned to the system support rails 10 each. The number of anchor rods 110 and anchor nuts 30 depends on the height of the wall section and the present load case.
    At a side facing the first formwork wall 100 side of the system support rails 10 a plurality of insulating panels P are arranged. These insulating panels P are held to each other via a tongue and groove system. On a top side of the uppermost insulating panel P, a holding means 40 engages, which establishes a connection between insulating panels P and at least one system support rail 10.
    The holding means 40 is shown in detail in Figures 4a and 4b, and includes the support plate 41 and a profile 43. On both sides of the profile 43 sockets 42 are mounted on the support plate 41. The profile 43 in turn has a plurality of openings 44 through which a connecting means can penetrate, which also passes through one of the openings 11 of a system support rail 10 and in this way establishes a connection between a system support rail 10 and the holding means 40. The profile 43 has a width such that it can be slid between a system support rail pair until a narrow side of the support plate 41 comes into contact with a side surface of the system support rails 10.
    For the production of a wall section, the procedure described below is preferred in the context of the present embodiment.
    The vertical system support rails 10 are aligned by means of the base plate 20 relative to the bottom plate B and, for example, supported by means of support struts 12, 13 with respect to an outer side of the wall section to be produced. The 11/23 11
    Support struts 12, 13 in this case engage the holding heads 50, 51.
    At a distance from the system support rails 10, a first formwork wall is arranged. The distance between the first shuttering wall 100 and a side of the system support rails 10 facing the first shuttering wall 100 defines the total thickness of the wall section to be produced, including the insulation. For example, a 24 cm concrete wall is made with 16 cm perimeter insulation.
    At the side facing the first formwork wall 100 side of the vertical system support rails 10, the insulating panels P are arranged. In order for the insulating panels P to remain secured in this orientation, the support means 40 is aligned and fixed to the system support rail pair 10, and then nails are driven through the sockets 42. These nails penetrate into the uppermost insulating panel P, thus securing the insulating panels P to a side surface of the system support rails 10.
    Some of the insulating panels P are provided with holes so that the tie rods 110 can penetrate them. The anchor rods 110 are conventional anchor rods which are provided in the region in which concrete is to be filled between the insulation panels and the first shuttering wall 100, with a plastic tube 111 and with two sealing cones 112. After the anchor rods 110 have each been aligned and passed through the holes of the insulating panels P, the respective anchor nut 30 can be aligned and fixed to the system support rails 10. Subsequently, the respective anchor rod 110 is screwed to the corresponding nut 30.
    In a subsequent method step, the space remaining between the first shuttering wall 100 and the insulating panels P is filled with concrete so as to form the wall section to be produced. After the concrete has cured, the anchor rods 110 are released from the anchor nuts 30, and the first formwork wall 100 can be removed from the finished wall portion. Furthermore, the holding means 40 are released, and the support struts 12, 13, the cross rail 60 and the holding heads 50, 51 are removed, so that finally the system support rails 10 and the base plate 20 can be removed. Thus, there remains the wall portion comprising the concrete portion and the insulating layer / perimeter insulation made of the insulating panels P.
    It can be seen that individual process steps do not have to be carried out in the order described. Furthermore, certain components or assemblies can be installed pre-assembled, for example, the base plate 20, the system support rails 10 and the crossbar60. Since the insulation panels P provide a concrete density butt joint and are sized with an upper protrusion corresponding to the ceiling thickness, the outer protrusion of a Deckenrandabschalung can be replaced, and there is no risk for thermal bridges. Consequently, a possible insulation of the overlying storey walls can be placed directly. 13/23
