Description

The present invention relates to a structural system for the manufacture of structures. A structure can be a bridge or a tunnel, for example. Formwork elements can be attached to the supporting structure in order to be able to pour concrete sections for structures.

From the pamphlets DE 10 2007 047 438 A1 and DE 10 2007 047 443 A1 Formwork arrangements for cantilevered bridges are known. A formwork arrangement comprises beam arrangements with longitudinal beams and transverse beams. There are also diagonally aligned struts for additional stabilization.

A formwork arrangement for the cantilever construction of bridges with a carrier, which is designed as a closed, box-like hollow profile, is from the publication DE 10 2007 047 439 A1 known. Front sides have three rows of holes running parallel to one another.

The pamphlets EP 1 388 625 B1 , EP 2 503 077 A1 , DE 10 2009 005 657 A1 , WO 2013/149771 A1 , WO 2005/054604 A1 , EP 1 457 601 B1 , WO 2017/174761 A1 , DE 601 12 332 T2 disclose supporting structures for the manufacture of structures with beams and struts.

From the pamphlet DE 10 2016 200 868 A1 a connector for beams is known, each beam comprising two U-profiles. The U-profiles are welded together using connecting plates. The connector extends into a space between the two profiles when a carrier is attached to the connector. Profiles and beams have bores so that the beam can be attached to the connector using bolts.

From the pamphlet DE 10 2016 217 622 A1 a coupling for beams is known which are used for the production of structures. A beam consists of two interconnected U-profiles. There is a space between the two profiles. Wall areas of the supports adjoining the intermediate area each have two rows of holes running parallel to one another. Carriers each with two rows of holes running parallel to one another are from the publication DE 10 2005 030 336 A1 known. The DE 10 2008 015 682 A1 discloses beams with two profiles that are connected to each other. The two profiles of a carrier have a gap. Wall areas of the supports adjoining the intermediate area each have two rows of holes running parallel to one another. Profiles for a carrier with three rows of holes, which run parallel to each other, are in the publications EP 2 365 159 B1 , EP 2 871 304 B1 , and EP 2 518 239 B1 shown.

The object of the invention is to create a further developed supporting structure system for the production of buildings.

The object is achieved by the subject matter with the features of the first claim. Advantageous refinements result from the secondary claims.

The invention relates to a supporting structure system for the production of buildings with at least one beam, a first connector, a second connector and a plurality of bolts.

A connector is a component that can be fixedly connected to a plurality of beams and / or struts using bolts. A connector together with a bolt thus connects, for example, a carrier with another carrier or a carrier with struts. Beams and struts of a structure are used to carry loads. Beams are designed to be mechanically more resilient than struts. Carriers also include a plurality of bores in order to be able to attach connectors flexibly to a carrier, for example. A strut, on the other hand, is attached to a connector at one end. The aforementioned components of the girder are made of a resilient material such as steel in order to withstand the weights that occur during the construction of structures. A construction with girders and struts, which are firmly connected to one another with the aid of connectors and bolts, is a supporting structure within the meaning of the present invention.

The first and second connectors can be attached to the carrier at the same level. The arrangement of the first and second connector on the carrier then differs essentially only in the side on which the respective connector is attached to the carrier. If, for example, one connector is fastened in the middle of the carrier, as seen along the length of a carrier, and the other connector can then also be fastened in the middle of the carrier, the two connectors are fastened to the carrier at the same height. For example, is the one connector along the length of a beam is attached to one end of the carrier and if the other connector is fastened to the other opposite end of the carrier, the two connectors are not fastened at the same height on the carrier but offset from one another. The position of the bolts that are used for fastening is decisive. If the bolts with which a first connector is fastened to a carrier are arranged completely offset from the bolts with which a second connector is fastened to the carrier, then the two connectors are not fastened to the carrier at the same height. Otherwise, the two connectors are attached to the carrier at the same height.

The first connector may be attached to the bracket by one or more first bolts.

The second connector may be attached to the bracket by one or more second bolts, in which case the second connector is not attached to the bracket by the first bolts.

This makes it possible to first attach a first connector to the carrier with the aid of first bolts and then to attach a second connector at the same height. It can be mounted flexibly. If necessary, a second connector can be attached at a later point in time in addition to the already attached first connector at the same height as the carrier without having to dismantle the first bolts. The structure can therefore be flexibly assembled with little assembly effort.

In one embodiment, the first carrier can also be fastened to the carrier by the second bolts. This enables additional stabilization without having to increase the installation effort.

The system may comprise a third connector which may be attached to the bracket also at said same level by one or more third bolts rather than the first and second bolts. This makes it possible to first attach a first connector and optionally a second connector at the same height to the carrier and then to attach a third connector at the same height. It can be assembled flexibly in a further improved manner without having to operate an increased assembly effort. If necessary, at a later point in time in addition to the first connector and the optionally available second connector A third connector can be attached to the same height on the carrier without having to loosen the first and / or second bolts.

The one or more third bolts can also secure the first and / or second connector to the carrier. This enables additional stabilization without having to increase the installation effort.

The carrier can have two profile elements, the two profile elements of the carrier being connected to one another. In section, the profile elements can be T-shaped or U-shaped, for example. However, other forms are also possible. For reasons of stability and weight, however, a U-shape is preferred.

There can be a space between the two profile elements. The first connector can comprise a first wall area which can extend into the profile element interspace. This first wall area of the first connector can be fastened to the carrier with the aid of first bolts and / or with the aid of second bolts and / or with the aid of third bolts. The first connector can comprise a second wall area which can extend into the profile element interspace. This second wall area of the first connector can be fastened to the carrier with the aid of first bolts and / or with the aid of second bolts and / or with the aid of third bolts.

If the first connector comprises the aforementioned first wall area and the aforementioned second wall area, then an interspace can remain between the two wall areas. This creates a receiving space into which, for example, a leg or a differently shaped wall area of a second connector can be inserted. The second connector can comprise a first wall area which can extend into the space between the two wall areas of the first connector, that is to say into the receiving space. This first wall area of the second connector can be fastened to the carrier with the aid of second bolts and / or third bolts. Such a wall area, which can extend into the receiving space of the first connector, allows stability advantages to be achieved without having to provide an excessively large installation space or an excessively large amount of material.

The second connector can comprise a second wall area which can extend into the space between the two wall areas of the first connector, that is to say into the receiving space. This second wall area of the second connector can be fastened to the carrier with the aid of second bolts and / or third bolts.

The second connector can include a first leg that can reach into the space between the two wall areas of the first connector, preferably with little play, in order to be able to insert the leg easily on the one hand and to achieve stability advantages in the event of an excessively high load on the other. This first leg of the second connector can be attached to the carrier with the aid of second bolts and / or third bolts.

The second connector can comprise a second leg, which can reach into the space between the two wall areas of the first connector and, for the reasons mentioned above, also preferably with little play. This second leg of the second connector can be attached to the carrier with the aid of second bolts and / or third bolts. By providing two legs, further improved stability advantages can be achieved.

The first connector can include a first pocket. There are then not only two wall areas through which a receiving space is provided, but also further components such as tabs that also delimit the receiving space beyond. So there can be a tab that delimits a receiving space to a bottom. Two tabs can be provided through which a pocket-like opening is provided and in this way further delimit the receiving space. A leg or a wall area can then only be inserted through this pocket-like opening in the course of an assembly in order to get into the receiving space of the first connector. The first pocket can comprise the aforementioned first wall area of the first connector and the aforementioned second wall area of the first connector. The first wall area or the first leg of the second connector can extend into the first pocket. Since the relative position between the first connector and the second connector is predetermined if both connectors are to be mounted at the same height, assembly delays can be avoided in an improved manner.

The first connector can include a second pocket. The second pocket can comprise the aforementioned first wall area of the first connector and the aforementioned second wall area of the first connector. The second wall area or the second leg of the second connector can extend into the first pocket. In this way, stability advantages can be achieved in a further improved manner and delays during assembly can be avoided.

Each connector can be located at the same level on a different side of the carrier. Connectors can be mounted one after the other on different sides without having to loosen previously mounted bolts. It is possible to first attach the first connector to the carrier on one side using first bolts. Subsequently, at the same height, the second connector can be fastened on an opposite side of the carrier at the same height with the aid of second bolts without having to dismantle the first bolts. Subsequently, at the same height, the third connector can be attached at the same height with the aid of third bolts laterally and thus on a third side without having to dismantle the first and second bolts. For fastening the third connector, fastening of the second connector is not necessary. The first connector can therefore also be fastened to the carrier by first bolts and then the third connector with the aid of third bolts without having to loosen the first bolts.

If the first connector and the second connector are attached to opposite sides of the carrier, the first connector and the second connector usually form an angle of 180 °. If a third connector is attached to the side of the first connector, the first connector and third connector usually enclose an angle of 90 °.

In one embodiment, connectors can therefore enclose a 180 ° angle with one another. Connectors can form a 90 ° angle with one another.

Each connector can be connected to at least one strut.

The profile elements of a carrier can be U-shaped in cross section. The base of one U-shaped cross section can be connected to the base of the other U-shaped cross section, for example by one or more bolts. This one or several bolts can be passed through sleeves, which serve as spacers for the profile elements. The sleeves then ensure a distance between the base of one U-shaped cross section and the base of the other U-shaped cross section. An intermediate space is thus provided between the two profile elements. The profile elements of the carrier can also be connected to one another with the help of plates. Welded connections can be provided between the plates and the profile elements in order to fasten the plates to the profile elements. But ends of bolts can also be welded to the profile elements.

The carrier can comprise three parallel rows of holes, which are hereinafter referred to as first row of holes, second row of holes and third row of holes. The second row of holes is located between the first and third row of holes. Each row of holes in a carrier comprises a plurality of holes. In particular, each row of holes comprises at least five holes, preferably at least ten holes, particularly preferably at least 20 holes. Each row of holes runs in particular in a straight line. Holes can be round holes or elongated holes. The holes in the first and third row of holes are preferably exclusively round holes in order to achieve assembly advantages. The second row of holes, ie the middle row of holes, preferably comprises both round holes and elongated holes in order to achieve assembly advantages. Round holes and elongated holes alternate advantageously in the middle row of holes. For example, after exactly one round hole, exactly one elongated hole can follow and this can continue. The holes in a row are advantageously always at the same distance from one another. The holes of the first and third row of holes are advantageously exactly at the same height. The holes in the middle row of holes are advantageously arranged offset relative to the holes in the first and third row of holes.

The first connector can comprise three parallel rows of holes, which are hereinafter referred to as first row of holes, second row of holes and third row of holes. The second row of holes is located between the first and third row of holes. Each row of holes in the first connector includes a plurality of holes. The middle row of holes, i.e. the second row of holes, can only contain two holes. The second row of holes can also comprise more than two holes. The other two rows of holes generally have more than two holes, for example six or eight holes. Each row of holes runs in particular in a straight line. Holes can be round holes or elongated holes. The holes of the first, second and third row of holes however, they are preferably only round holes in order to achieve assembly advantages. The holes in each row of holes are advantageously always the same spacing from one another. The holes of the first and third row of holes are advantageously located exactly at the same height. The holes in the middle row of holes are advantageously arranged offset relative to the holes in the first and third row of holes. The holes are in particular arranged in such a way that they can be aligned with the holes of the three rows of holes in a carrier, so that bolts can be pushed through holes in the carrier and through the holes in the first connector. In the assembled state, all holes of the three rows of holes in the first connector are preferably aligned with holes in the three rows of holes in the carrier, so that in the assembled state, bolts can be pushed through all holes in the three rows of holes in the first connector.

A first bolt can pass through a hole of the first row of bracket and first connector so as to secure the first connector to the bracket. A first bolt can pass through a hole of a second row of bracket and first connector so as to secure the first connector to the bracket. A first bolt can pass through a hole of the third row of carrier and first connector so as to secure the first connector to the carrier.

The second connector can comprise two or three parallel rows of holes, which are referred to below as the first row of holes, the second row of holes and, if necessary, the third row of holes. The second row of holes can be located between the first and, if applicable, the third row of holes. Each row of holes in the second connector includes a plurality of holes. A second row of holes can only have two holes. The second row of holes can also comprise more than two holes. The one or two further rows of holes generally comprise more than two holes, for example four or six holes. Each row of holes runs in particular in a straight line. Holes can be round holes or elongated holes. However, the holes in the first, second and, if applicable, third row of holes are preferably exclusively round holes in order to achieve assembly advantages. The holes in each row are advantageously always the same distances from one another. The holes of the first and, if applicable, the third row of holes are advantageously located exactly at the same height. The holes of the second row of holes are advantageously arranged offset relative to the holes of the first row of holes. The holes are in particular arranged so that they can be aligned with the holes of two or three rows of holes in a carrier, so that bolts can be pushed through holes in the carrier and through the holes in the second connector. Preferably In the assembled state, all holes of the two or three rows of holes of the second connector are aligned with holes of two or three rows of holes in the carrier, so that in the assembled state, bolts can be pushed through all the holes of the two or three rows of holes in the second connector.

A second bolt can pass through a hole of a first row of holes in the bracket and the second connector, so as to fasten the second connector to the bracket. The first connector is then preferably also fastened to the carrier by the second bolt. A second bolt can pass through a hole of a second row of holes in the bracket and the second connector, so as to fasten the second connector to the bracket. The first connector is then preferably also fastened to the carrier by means of the second bolt. A second bolt can pass through a hole of the third row of holes in the bracket and the second connector, so as to fasten the second connector to the bracket. The first connector is then preferably also fastened to the carrier by the second bolt.

Support arrangement according to the preceding claim, characterized in that the second or the third connector includes an angle of 90 ° with the first connector. and / or that the second or the third connector is connected to the carrier by a bolt which passes through a hole in the second central row of holes.

In one embodiment, the first, second and / or third connector can be fastened to two carriers in the assembled state. A connector can therefore be used to firmly connect support to support and, moreover, support to struts. Since a plurality of connectors can be connected to two carriers in the assembled state, carriers can be mechanically connected to one another in a very stable manner. The assembly effort to be carried out for this is low. If a first connector with play has been pushed into the space of a carrier and a second connector with play has been pushed into a space of the first support, it can be installed with little effort. However, in the event of excessively high loads, additional protection is available so that the structure can withstand excessively high loads at all times.

A system according to the invention can advantageously comprise two differently dimensioned carriers, the width of the space always being the same for each carrier. It is then possible to fit accessories such as connectors into each To be able to use space in a suitable manner without having to dimension different accessories. This is especially true when the first and third rows of holes on the carrier are at the same distance from the adjacent outside. The holes in the first and third rows of holes then advantageously have the same spacing from one another, regardless of the other dimensions of each carrier. The holes can then also always be used for fastening the accessories without having to provide for different distances between the holes in the accessories. Alternatively, however, the accessory parts can also comprise holes arranged in such a way that some of these holes match the holes in a first carrier or another part of the holes match the holes in a differently dimensioned second carrier. The provision of a system with such differently dimensioned beams, but always the same width gaps comprising one or more accessories that can be inserted into the gaps and fastened to the girders, for example with the aid of bolts, independently solves the problem and is an independent invention. This independent invention can be combined with the features of the invention described so far.

The Figure 1 shows a carrier 1 with two profile elements 2 and 3. The profile elements 2 and 3 of the carrier are U-shaped in cross section. Each cross section therefore has a base 4 and two legs 5 extending from the base. Viewed from the base 4, the legs 5 point as in FIG Figure 1 shown to the outside. The base 4 of the profile element 2 is connected to the base 4 of the other profile element 3 by bolts 6. These bolts 6 are passed through sleeves 7, which serve as spacers. The sleeves 7 ensure a distance between the base 4 of the one profile element 2 and the base of the other profile element 3. An intermediate space 8 is thus provided between the two profile elements 2 and 3. The bolts 6 can comprise a thread at one end onto which a nut is screwed and at the other end a head so as to act as a fastening element. But it is also possible to weld the ends of each bolt 6 to the respective base 4. Sleeves 7 are then not required to provide a distance. Sleeves 7 do not necessarily have to be provided in order to ensure a distance between the two profile elements 2 and 3.

Each profile element 4 comprises three rows of holes 9, 10 and 11 that run parallel and in a straight line. The second row of holes 10 runs between the first row of holes 9 and the third row of holes 11. The holes of the three rows of holes are round holes. Each row of holes 9, 10 and 11 has more than ten holes. For assembly reasons, the first row of holes 9 and the third row of holes 11 have more holes than the second row of holes 10. The holes of the first and third row of holes 9 and 11 are arranged at the same height. The holes of the second row of holes 10 are offset in relation to this in order to achieve assembly advantages. The diameter of the holes in the second row of holes 10 is advantageously greater than the diameter of the holes in the first row of holes 9 and the third row of holes 11. The diameters of the holes in the first row of holes 9 and the third row of holes 11 are advantageously the same.

The bolts 6 can, for example, be passed through holes in the first rows of holes 9 and through holes in the third rows of holes 11 in order to connect the two profile elements 2 and 3 to one another in a stable manner without having to use an excessive number of bolts 6.

In order to be able to provide carrier 1 for different load situations, the profile elements 2 and 3 can be dimensioned differently from carrier to carrier. However, the distances between the base 4 of the one profile element 2 and the other base 4 of the profile element 3 do not advantageously differ. Examples with dimensions for this are shown in section in FIG Figures 2 and 3 shown. The space between each carrier is therefore of the same width, regardless of the other dimensions of each carrier. For example, the width of the gap is as in FIG Figures 2 and 3 shown for each beam 64 mm. The dimension of a first carrier can, however, differ from the dimension of a second carrier, for example by the distances between the two legs of each U-shaped cross section. Thus, in the case of a first carrier, the distance between the two legs of a U-shaped cross section as in FIG Figure 2 shown to be 120 mm. The distance in the case of a second carrier can be between the legs of a U-shaped cross section as in FIG Figure 3 shown to be 200 mm in order to provide differently dimensioned carriers for different load situations. The distance between outer ends of legs of U-shaped profile elements can be in a first carrier as in Figure 2 shown to be 172 mm. The distance between outer ends of legs of U-shaped profile elements can be in a second carrier as in the Figure 3 shown to be 214 mm.

The Figure 4 Figure 12 shows a side view of a first connector 12. Die Figure 5 FIG. 8 shows a sectional illustration rotated by 90 ° through the first connector 12.

The first in the Figures 4 and 5 The connector 12 shown comprises two side walls 13. The two side walls 13 are spaced apart from one another, so that an intermediate space 14 remains between the two side walls 13. The two side walls 13 are connected to one another by L-shaped tabs 15. The L-shaped tabs 15 are welded to the side walls 13. An opening 16 remains between the short legs of the L-shaped tabs 15. There is another straight, strip-shaped tab 17 which lies opposite the opening 16. This straight, strip-shaped tab 17 also connects the two side walls 13 to one another and is attached to the side walls 13 by welded connections. The straight flap 17 forms the bottom of a pocket. A leg of a second connector can be inserted through the opening 16. The leg of the second connector can be selected to be so long that it can be placed on the strip-shaped tab 17. However, one leg of a second connector can also be so long that it does not extend to the bottom or to the Holes of the first row of holes 19. The cross section of a leg of a second connector is advantageously adapted to the opening 16 such that the leg can be inserted into the opening 16 with only little play. If, for example, the second connector is excessively stressed in the assembled state and the second connector is bent as a result, additional stabilization is then available, for example through the side walls 13.

The side walls 13 widen towards the bottom, as shown in FIG Figure 4 will be shown. The widened area 18 of the side walls 13 prevents the first connector 12 from being able to be pushed through two profile elements 2, 3 of a carrier 1. The other area of the first connector 12, which is not widened in comparison therewith, can be inserted into the space between two profile elements 2, 3 of a carrier 1 on one side. In order to be able to connect the inserted, non-widened area of the first connector 12 to the carrier by bolts, this non-widened area has a total of three rows of holes 19, 20, 21. The first row of holes 19 comprises six round holes runs parallel to the second row of holes 20 and parallel to the third row of holes 21. The third row of holes 21 also comprises six round holes. The middle row of holes 20 comprises only two round holes. The diameter of the holes in the middle row of holes 20 are larger than the diameter of the holes in the two other rows of holes 19 and 21. The holes in the middle row of holes 20 are offset relative to the holes in the two other rows of holes 19 and 21. The distance between the holes of each row of holes 19 and 21 is always the same. The holes of the first and third rows of holes 19 and 21 are arranged at the same height relative to one another. The holes in each row of holes 19, 20, 21 run in a straight line. The rows of holes 19, 20, 21 are arranged so that bolts can be inserted through holes in the rows of holes 19, 20, 21 and at the same time through holes in the rows of holes 9, 10 and 11 of the profile elements 2 and 3 when the first connector 12 with its provided, not widened area has been suitably inserted into the space between the carrier one. The widened area 18 comprises one or more holes 22, for example 3 holes, which are used to attach struts. For stabilization, the widened area 18 can also include one or more transverse plates 23, which can be connected to side walls 13 by welded connections.

The Figure 6 FIG. 3 shows a first connector 16 fastened to a carrier 1. The first connector 16 is fastened to one end of the carrier 1 by means of two first bolts 24. A first bolt 24 is through two opposite holes of the rows of holes 9 of the carrier 1 and through two corresponding, oppositely arranged holes of the rows of holes 19 of the first connector 16. Another first bolt 24 is inserted through two opposite holes of the rows of holes 11 of the carrier 1 and through two corresponding, oppositely arranged holes of the rows of holes 21 of the first connector 16. The bolts 24 can have a head on one side, which prevents the bolts 24 from being pushed completely through the holes in the rows of holes 9 and 11 of the carrier 1. On the opposite side, the bolts can have a hole through which a split pin is pushed. Each split pin then prevents the bolts 24 from being pulled out again. The first connector 16 is then attached to the carrier 1 as intended.

However, the first connector 16 could also have been pushed into the intermediate space of the carrier 1 at another point and could have been fastened to the carrier 1 with first bolts 24.

The Figure 7 Figure 11 shows a side view of a second connector 25. Die Figure 8 shows a sectional view rotated by 90 ° through the second connector 25. The second in FIG Figures 7 and 8 The connector 25 shown comprises two side walls 26. The two side walls 26 are spaced apart from one another, so that a gap 27 remains between the two side walls 26. The two side walls 26 are connected to one another on one side by a tab 28. The tab 28 is welded to the side walls 26. On the other side, the two side walls 26 are welded to a widening 29. The widening 29 is in section as in Figure 7 shown U-shaped. The widening 29 can be reinforced by one or more welded-in metal sheets 30.

The widening 29 prevents the second connector 25 from being able to be pushed through two profile elements 2, 3 of a carrier 1 or through side walls 13 of a first connector 12. The other area of the second connector 25, which is not widened in comparison therewith, can be inserted into the opening 16 of the first connector 12. In order to be able to connect the inserted, non-widened area of the second connector 25 to the carrier 1 by means of second bolts, this non-widened area, which is formed by the side walls 26, has a total of two rows of holes 31 and 32. The first row of holes 32 runs parallel to the second row of holes 31. The two rows of holes 31 and 32 are arranged so that the second Bolts can be inserted through holes of the rows of holes 31 and 32 and at the same time through holes of the rows of holes 10 and 11 of the profile elements 2 and 3 if the second connector 25 with its intended, non-widened area has been suitably inserted into the space between the carrier 1 . The first row of holes 32 comprises four round holes which are equidistant from one another. The second row of holes 31 comprises two round holes. The holes in the second row of holes 31 are offset from the holes in the first row of holes 32. The diameters of the holes in the second row of holes 31 are larger than the diameters of the holes in the first row of holes 32.

The widening 29 comprises one or more holes 33 which are used to attach struts.

The Figure 9 shows two carriers 1 which are firmly connected to one another by a first connector 12. Is the second connector 25 as in Figures 7 and 8 shown dimensioned so that its leg, which is formed by the side walls 26, cannot reach to the bottom 17 of the pocket of the first connector 12 and also not to the one in FIG Figure 6 The lower rows of holes 9 and 19 shown, all of the overlapping holes of the lower rows of holes 9 and 19 can be used to fasten the two supports 1 to the first connector 12 with the aid of first bolts 24. In the Figure 9 it is shown that, for example, a total of eight first bolts 24 can be present in order to fasten the two carriers 1 to the first connector 12. Nevertheless, the second connector can be pushed through the opening 16 of the first connector 12 at the same height on the opposite side of the carrier, as indicated by an arrow, until further pushing is finally prevented by the widening 29.

If the second connector 25 has been inserted into the opening 16 of the first connector 12 as far as possible, the second connector 25 can then be attached to the two carriers 1 with the aid of second bolts 34, as shown in FIG Figure 10 will be shown. The bolts 34 are pushed through holes in the upper row of holes 11 of the two supports 1. These bolts 34 then also extend through holes in the upper row of holes 21 of the first connector 12 and through holes in the upper row of holes 32 of the second connector 25. In this way, these bolts 34 not only fasten the second connector 25 to the two carriers 1, but also the first connector 12. The additional loads that can occur, inter alia, due to struts the second connector 25 can be compensated for by inserting a leg of the second connector 25 into the space between the two carriers 1. Since the leg of the second connector 25 has been inserted with play, this leg only stabilizes when there is excessive load.

The Figure 11 Figure 3 shows a side view of a third connector 35. Figure 12 shows a sectional view rotated by 90 ° through the third connector 35 Figure 13 shows a plan view of the third connector 35.

The third in the Figures 11 to 13 The connector 35 shown comprises a U-profile with a base 36 and two legs in the form of in the side walls 37. The two side walls 37 are spaced apart from one another, so that a gap 38 remains between the two side walls 37. The U-profile is reinforced by one or more welded-in sheets 39, which are arranged, among other things, on the end faces.

There are two holes 40 in the base 36. The side walls 37 have, for example, one, two or three holes 41 which are used to attach struts. The diameter of the holes 40 corresponds to the diameter of the said rows of holes of the carrier and the first and second connectors which comprise the holes with the larger diameter.

With the aid of third bolts, the third connector 35 can be connected to the two carriers 1 as in FIG Figure 14 shown connected. The two third bolts lead through the two pairs of holes in the middle rows of holes 10 of the two supports 1, which are at the edge of the ends of the supports 1 in the Figure 10 are not yet occupied. These third bolts thus also fasten the first connector 12 and the second connector 25 to the girders 1 in addition. The load increases due to the large number of connectors 12, 25, 35 and the connected thereto in the Figure 14 also shown fastened struts 42. However, this highly stressed point in a supporting structure is additionally reinforced by the additional bolts and the additional connectors. The ends of the struts 42 can extend into the corresponding spaces of the connectors 12, 25, 35 for fastening to the connectors 12, 25, 35 and then be fastened to the connectors by means of bolts 43 as shown.

In the Figure 14 although only a third connector 35 is shown. However, another third connector 35 can also be attached at the same height and at the same height although on the back of the in the Figure 14 shown carrier 1 with the third bolt, with which the already in the Figure 14 shown third carrier 35 is attached. Is another third connector 35 on the back of the in the Figure 14 The carrier 1 shown is fastened to the carrier 1 by third bolts, so one or more struts 42 can also be fastened to this further third carrier 35.

The struts 42 can be rigid or adjustable in length. Struts are advantageously adjustable in length in order to be able to mount the supporting structure variably.

Instead of a strut, another component, such as a belt or an adapter, can also be attached to a connector. A connector fastened to the carrier 1 can also be firmly connected to a further connector instead of a strut, which in turn can be fastened to a further carrier.

In the Figure 14 the case is shown that the connectors are attached when two beams join. The connectors can, however, also be attached to the carrier 1 in an otherwise identical manner, away from the joint and thus away from both ends of the carrier.

The Figure 15 illustrates in more detail the attachment of the third connector 35 to a carrier 1 with the aid of third bolts 44 which lead through holes in the middle row of holes 10. Also shown is a cotter pin 45 with a pivotably connected locking ring 46. The cotter pin 45 is pushed through a hole in the bolt 44 and the locking ring 46 is folded over the end of the bolt 44 in order to secure the position of the cotter pin 45. The third connector 45 is then attached to the carrier 1. The Figure 15 shows that the third connector 35 can be attached to the carrier 1 independently of the two other connectors 12, 25. Correspondingly, the second connector 25 can also be attached to a carrier 1 independently of the other connectors 12 and 35.

However, two third connectors can also be attached to the carrier at the same height, namely opposite one another.

The Figure 16 shows another embodiment for a first connector 12. This embodiment differs from the first connector 12 already shown in the provision of two openings 16 through the two legs of a second connector can be inserted through. The two openings 16 are provided by a welded sheet metal 47 between the two openings 16. In addition, there are metal sheets 48 welded in at the edge to form the two openings. The Figure 16 shows that a multiplicity of bolts 49 can be used immediately to connect the first connector 12 to a carrier 1. As a rule, however, this does not make sense, since bolts 49 then have to be loosened again in order to be able to add a second connector 25. This in Figure 16 The embodiment shown shows a carrier 1 in which the middle row of holes 10 comprises alternating round holes and elongated holes.

Comparable to the Figure 8 show the Figure 17 a sectional view through a second embodiment of a second connector 25, which differs from that in FIG Figure 8 embodiment shown comprises two legs. The two legs are formed by side walls 26 which lie opposite one another in pairs and which are laterally connected to one another by welded metal sheets 50. These legs are inserted into the two openings of the Figure 16 first connector 12 shown inserted in order to fasten this second connector 25 in addition to the first connector 12 on a carrier. In contrast to the embodiment of a second connector shown in FIG. Eight, the connector according to FIG Figure 17 also a lower row of holes 51, so a total of three rows of holes 32, 31 and 51. For fastening to a carrier 1, second bolts are also inserted through these holes 51 and then also through the corresponding holes of a lower row of holes in the carrier or carriers 1 and at the associated first connector 12. The upper row of holes 32 and the lower row of holes 31 each consist of four holes which are arranged along a straight line. The middle row of holes 31 comprises two holes with a larger diameter compared to the holes of the upper row of holes 32 and the lower row of holes 51. The two holes of the middle row of holes 31 are offset in relation to the holes of the upper row of holes 32 and the lower row of holes 51. There is no such offset between the holes in the upper row of holes 32 and the lower row of holes 51.
