    1
    The invention relates to a temporary auxiliary bridge support device for track sections, preferably in a Weichenbe-rich, during the construction of structures under these track sections, with a ladder-like support grid having longitudinally extending side members and between these transverse transverse beams, the rails of the Support track sections.
    Such a temporary auxiliary bridge support device is known from AT 505 953 Bl. Such temporary support means are used when previously fabricated structures are to be pressed under the respective track sections. As a rule, passages or passages are built as structures in this press-through process. The temporary support means then make it possible to maintain the railway operation during the construction virtually unrestricted.
    Since the construction of such structures, such as passages or passages, is known in the press-through method, cf. the aforementioned AT 505 953 Bl, may be a more detailed description unnecessary. Of particular interest here is that the temporary Ab-supporting means in the manner of an auxiliary bridge have a supporting grid with longitudinal members and cross members, wherein between the cross members usual thresholds are arranged. The cross members are fixed in the known construction with the longitudinal members at predetermined locations or even releasably fixed, e.g. by form fit, plug connections, screw connections, clamping connections, welded connections or even adhesive connections. A problem here is that the existing sleepers of the track body are not necessarily laid at regular intervals, but that the threshold distance is usually always variable. This leads to problems in the known art, if fixed joints between longitudinal beams and cross members are given. Moreover, for other reasons, such as strength reasons, it is sometimes desirable to change the spacing of the cross members and thus their junctions on the side rails. However, such variable distances are possible in the known construction only with an increased effort in the sense of a custom-made. 2
    The object of the invention is therefore to propose an auxiliary bridge Ab support means or a support grid for this, which has a comparatively high flexibility and versatility in training, for example with regard to variable threshold distances. Furthermore, the present support grid or the auxiliary bridge support device should be suitable for track sections with points, with points in particular requiring increased flexibility in the support of the rails of the track sections through the support grid.
    To achieve the object, the invention provides an auxiliary bridge support device as stated above, which is characterized in that the longitudinal members each have in a vertical web at least one row of holes with uniformly spaced holes and attached to the cross members end face end plates, e.g. are welded, which have at least two in their arrangement of those of the holes of the rows of holes of the side members corresponding holes, wherein in the assembled state of the support grid, the cross member with the side rails by means of bolts which are defined by corresponding holes in the cross member end plates and in the Longitudinal beams extend, are connected. In particular, the longitudinal members each have two rows of holes one above the other, and the cross member end plates corresponding to two times two holes next to each other or on top of each other.
    With the present auxiliary bridge support means the stated objective is met in an advantageous manner, and it is a high flexibility and versatility in the formation of the supporting grid, especially for points areas, achieved, the rows of holes or holes in the manner of a breadboard a flexible spacing design allow the connection of the cross member to the side members. The holes on the longitudinal and transverse beams (or on the end plates) can be prepared in advance, even in the production of these carriers and face plates, in the factory, etc., so in this regard no special, costly attachment measures on site, 3 in the construction of the support grid above the building to be built, are required. It can be the cross member with their end plates at the respectively desired location, with screws via suitable pairs of holes in the side rails, are connected so that the desired adaptable fixation of the cross member is made possible on the side rails. As a result, the cross member can be easily installed on site at points between the usual thresholds and at points in points areas where they hinder any construction parts of the points, without the need for special, expensive measures would be necessary.
    A particular advantage of the construction according to the invention lies in the fact that, according to the screw connections between the cross members and the longitudinal members, a subsequent disassembly, i. an extension of the cross member is facilitated by screwing. As a result, a multiple use of the longitudinal and transverse beams of the support grid is easily possible.
    The aforementioned formation of two rows of holes one above the other in the longitudinal members and the corresponding attachment of two times two holes on the cross member end plates provides, inter alia, the advantage of a high stability in the connection of the cross member with the side members, without affecting the strength of the side members noticeably becomes.
    When providing two rows of holes one above the other, it is also possible, as with the provision of only a single row of holes, to provide the holes on the longitudinal members in such a way that the strength of the longitudinal members is maintained as far as possible. In the case of a single row of holes, the holes may be located slightly below the longitudinal axis of the respective longitudinal beam, in the case of two rows of holes, the upper row of holes may be located near the longitudinal axis of the longitudinal beam, spaced above it, whereas the other row of holes may be deeper, for example already in the vicinity of a flange of the longitudinal member in the case of I-profile side members. Through this TiefSetzung the holes can also be a subsea attachment of the cross member can be achieved, which is especially advantageous if, on the 4th
    Cross beams still support body are mounted in the manner of sleepers, on which then rest the rails. By providing the rows of holes, namely in particular the respective upper row of holes in the case of two rows of holes, near the longitudinal axis of the side members, as already indicated, the strength of the side members is only slightly affected by the holes. On the other hand, can be accomplished by means of the support body height compensation or adjustment.
    It is thus generally of particular advantage if the row of holes (n) are offset eccentrically downwards on the web of the respective longitudinal member, for a deep-set attachment of the cross members.
    To increase the strength of the side members can also be provided if desired - that are attached to the side rail webs lining plates with corresponding holes. These lining plates are thus at the web of the side members, but they have smaller dimensions than the web to leave sufficient space in the end and corner regions of the side members, such as where there are curves. Furthermore, it is advantageous if face plates are fastened to the end faces of the side members, for example for pairwise longitudinal connection of side members. However, these front or head plates on the longitudinal beams not only allow one another longitudinal supports behind each other, with the help of threaded bolts, but they can also be used for the storage of the longitudinal beams at below it located bearing elements, such as Pfahlkopffundament on bored piles
    As mentioned above, support bodies can additionally be provided on the cross members, in particular in the case of a deep-mounted attachment, on which the rails then rest. Here it is of particular advantage when wooden beams are mounted on the cross beams, which support the rails in the manner of sleepers. There are thus in this embodiment, in addition to the existing thresholds in the track section or in the switch area, namely in the spaces between the thresholds, mounted on the low-set cross beams Holzboh-len-support body. These wooden planks are for rail fastening - similar to thresholds - of particular advantage, compared with a direct support of the rails on the cross members, which are usually made of steel, v.a. because then a significantly reduced noise is given. Also, in the case of direct support of the rails on the cross members, limited variability in the attachment of the rails through given bolt holes is to be expected, in contrast to the construction with wooden planks where holes for rail fasteners can be drilled on site. It is also an advantage that wooden planks are easily exchangeable. The wooden planks can for example consist of larch wood.
    For the attachment of the wooden planks, it has proven to be particularly advantageous if the cross member of them upwardly projecting, e.g. wear welded threaded bolts that extend through holes in the wood bolts. In this way, a quick, easy installation of the wooden planks on the cross members is made possible on the spot.
    A particularly advantageous embodiment is characterized in that the cross member, possibly the wooden planks carried by them, in turn, in the longitudinal direction of the supporting grid, alternately bear rail fasteners or compensating plates for the attachment of the rails. It follows thus - in the rail direction - alternately known rail fasteners on the one hand or - if necessary - compensating plates for height adjustment, so that the rails rest fully on the cross members or on the wooden planks of the cross member.
    Preferably, the side rails rest on transversely extending shelf supports, preferably with the interposition of height compensation plates, e.g. Steel sheets.
    The invention will be further explained with reference to preferred embodiments shown in the drawings, to which, however, it is not intended to be limited. In detail in the drawing:

    In FIGS. 1, 2 and 3, a part of a temporary auxiliary bridge support device is illustrated in a partial longitudinal section (FIG. 1), in a partial cross section (FIG. 2) and in a partial plan view (FIG. 3) , This auxiliary bridge support device 1 is used to support track sections 2, 3, for example in a switch region 4 (see FIG. 3), with rails 5A, 5B or 6A, 6B (track sections 2 and 3, respectively), if an underpass Structure 7 (see FIGS. 1 and 2) is erected at these track sections. Such an underpass structure 7 is shown in Fig. 1 schematically, partially. Further, from Fig. 1 as well as from Fig. 2 bored piles 8 with Pfahlkopffunda-elements 9 can be seen, the actual auxiliary bridge 1 ', more precisely their side members 10, store. The bored pile 8 * shown on the left in FIG. 1 according to the illustrations of these figures with its pile-head foundation 9 'is broken off during the pressing-through work during the erection of the structure 7.
    With regard to the pressing through of such an underpass structure 7, reference may be made to AT 505953B1 8 for the sake of simplicity. The present description can therefore be limited to the specific design of the auxiliary bridge Abstützeinrich-device 1 and auxiliary bridge 1 'in detail.
    The longitudinal members 10, s. Fig. 2, together with a corresponding number of cross members 11 a support grid 12, s. This support grid 12 is, as mentioned, arranged in the present embodiment in a switch area 3, in which the two side members 10 are relatively far apart, with two tracks 5 and 6, i. in Fig. 3 only schematically indicated by simple lines rails 5A, 5B and 6A, 6B are arranged. The side members 10 are as well as the cross member 11 generally formed by I-beam or double-T-carrier, wherein the cross member 11 are closed on a large part of its length laterally with plates 13, see except Fig. 1 and Fig. 2 and FIGS. 9, 10 and 11.
    2, a part of a rail vehicle 14 is schematically illustrated with dashed lines that travels on the rails 6A, 6B, that is to say the track 3 according to FIG.
    According to Figures 1 and 2, the longitudinal rails 10 are on slide-in carriers 15, wherein steel plates 16 may be interposed for a height compensation. The Pfahlköpffundamente 9 are with per se conventional bearings 17 {s. e.g. Fig. 1) provided for the longitudinal members 10.
    The drawer carrier 15 may be placed on roller box or steel rollers 18.
    As further shown in Fig. 1 it can be seen, the individual cross member 11 are relatively low relative to the longitudinal members 10, and they are between thresholds 19, which are indicated in Fig. 1 only very schematically attached. The cross member 11 are provided with wooden planks 20, as will be explained in more detail below. 3, in the finished state in the course of each rail 5A to 6B alternately rail fastenings 21 with ribbed plates and - on the next cross member 11 and the next wooden board 20 Equivalent plates 22, for example made of steel, mounted so that the respective rails 5A to 6B rest on the wooden planks 20 of the individual cross member 11 fed.
    The two side members 10 have two rows of eccentric rows 23, 24 with respect to their longitudinal axis {center axis) x-x (see Fig. 4) in their webs 25, as can be seen in particular from Figs. The holes 26 of the two rows of holes 23, 24 are equidistant, e.g. about 8 cm, arranged from each other, so that there is a hole pattern that is suitable for a flexible connection of the cross member 11 by screwing. This screw is also explained below with reference to FIG. 14 in more detail.
    Corresponding rows of holes 23 'and 24' with holes 26 'are provided in a on the respective inner side of the side members 10 (ie the other side member 10 facing side) mounted lining plate 27 which is fixed to the web 25, for example, when screwing the cross member 11 , but possibly also already in advance on the web 25 of the respective longitudinal member 10, for example by welding, gluing, etc., may have been attached. The lining sheet can, as is apparent from FIGS. 4 and 5, also be present in several parts per longitudinal member 10, see the gap 27 'in FIGS. 4 and 5. This makes it easier to manufacture, but also to assemble.
    The lining plate 27 reinforces the respective longitudinal member 10, but is kept smaller in size than the web 25 of the longitudinal member 10, so as to the two front ends of the respective longitudinal member 10 as well as in the lower region of the web 25, where the latter via a rounding in a corresponding flange 28 passes to leave free space. 10
    At the front ends, the longitudinal members 10 are closed by a front or top plate 29, see Fig. 4 except in particular also Fig. 7 and 8, wherein each end plate 29 is provided with holes 30, so as to connect in the longitudinal direction successive longitudinal beams 10 by means of threaded bolts and nuts (not shown) to allow.
    Similarly, the cross member 11 are closed at their ends or end faces by face plates 31; However, these end plates 31 are comparatively high, s. in particular Fig. 9 and 12, so that they protrude in height above the actual I-cross member 11 and are provided in this projecting region as well as in the region of the cross member 11 itself with holes 32.
    Both the end plates 29 at the front ends of the longitudinal members 10 and the end plates 31 at the ends of the cross member 11 may be fastened by welding to the respective carriers 10 and 11, for example.
    As further seen from Figs. 9, 10, 11 and 14, the actual cross member 11 carry on its upper side perpendicularly projecting from them threaded bolts 33, which are welded, for example, to the existing steel cross beams 11. On these threaded bolts 33, the wooden planks 20, which have corresponding holes, postponed, and then they are screwed by means of threaded nuts 34 on the respective cross member 11. The wooden planks may also have corresponding counterbores 35 (e.g., Fig. 10) such that the threaded nuts 34 do not protrude above the top of the wooden planks 20.
    14, the individual cross member 11 are connected by means of screw 36 with the webs 25 of the side members 10, with corresponding, as appropriate viewed hole pairs 26 and 26 '(in the lining plate 27) in accordance with the holes 32 of the respective end plate 31st of the cross member 11 are selected, through which the threaded bolt 37 of the screw 11 36 are inserted, as shown in FIG. 14 can be seen.
    In the case of a correspondingly narrow hole pattern (eg with a pitch of about 8 cm) is given a high flexibility or versatility in terms of the connection of the cross member 11 to the side members 10, so that, for example, the existing points components 19 or any designs in the Switch point 4 can be avoided, except for the adaptation to the - variable - threshold distances.
    The formation of the end plates 31 for the cross member 11 with the above projecting area, together with the special arrangement of the rows of holes in the webs 25 of the side members 10 a deep connection of the cross member 11 with the side members 10, s. Also Fig. 14, whereby the attachment of the wooden planks 20 is made possible on the cross beams 11. Thus, the top of the cross member 11 including wooden planks 20 substantially correspond to the top of the thresholds 19, so that the rails 5A to 6B - also in switch areas 4, as shown in FIG. 3 - can find a good circulation. The holes for the rail fasteners 21 and the balancing plates 22 can be easily drilled on site depending on the track in the wooden planks 20.
