Description

[0001] The present invention relates to a support structure system for the construction of structures. A structure can be, for example, a bridge or a tunnel. Formwork elements can be attached to the support structure in order to cast concrete sections for the structures.

[0002] Formwork arrangements for the cantilever construction of bridges are known from publications DE 10 2007 047 438 A1 and DE 10 2007 047 443 A1. A formwork arrangement comprises girder arrangements with longitudinal and transverse girders. Diagonally aligned struts are also used for additional stabilization.

[0003] A formwork arrangement for the cantilever construction of bridges with a girder designed as a closed, box-like hollow profile is known from publication DE 10 2007 047 439 A1. The end faces have three parallel rows of holes.

[0004] The publications 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 structural systems for the manufacture of buildings with beams and struts.

[0005] German patent application DE 10 2016 200 868 A1 discloses a connector for beams, wherein each beam comprises two U-profiles. The U-profiles are welded together via connecting plates. The connector extends into a gap between the two profiles when a beam is attached to the connector. The profiles and beams have bores such that the beam can be attached to the connector using bolts.

[0006] From German patent application DE 10 2016 217 622 A1, a coupling for beams used in the construction of buildings is known. A beam consists of two interconnected U-profiles. There is a gap between the two profiles. Wall sections of the beam adjacent to this gap each have two parallel rows of holes. Beams with two parallel rows of holes are known from German patent application DE 10 2005 030 336 A1. German patent application DE 10 2008 015 682 A1 discloses beams with two interconnected profiles. The two profiles of a beam have a gap between them. Wall sections of the beam adjacent to this gap each have two parallel rows of holes. Profiles for a support with three rows of holes running parallel to each other are shown in the publications EP 2 365 159 B1, EP 2 871 304 B1, and EP 2 518 239 B1.

[0007] US 2006 / 0144006 A1 discloses a beam connection device for connecting a beam flange to a flange attached to a column. WO 02 / 066760 A1 describes a tubular structure with several elongated C-shaped channels having lips that touch along their longitudinal direction. This structure can be used as a beam.

[0008] The purpose of the invention is to create a more advanced structural system for the construction of buildings.

[0009] The problem is solved by the device with the features of the first claim. Advantageous embodiments result from the dependent claims.

[0010] The invention relates to a structural system for the manufacture of buildings comprising at least one beam, a first connector, a second connector and a plurality of bolts.

[0011] A connector is a component that can be rigidly connected to multiple beams and / or struts using bolts. A connector, along with its bolts, connects, for example, one beam to another or a beam to struts. Beams and struts in a structure serve to bear loads. Beams are designed to be mechanically stronger than struts. Beams also include a multitude of holes to allow, for example, the flexible attachment of connectors. A strut, on the other hand, is attached to a connector at one end. The aforementioned components of the beam are made of a durable material such as steel to withstand the weights encountered during construction. A structure with beams and struts rigidly connected to one another using connectors and bolts is a load-bearing structure within the meaning of the present invention.

[0012] The first and second connectors can be attached to the beam at the same height. The arrangement of the first and second connectors on the beam then differs essentially only in the side on which each connector is attached. For example, if one connector is attached at the center of the beam (viewed along its length), and the other connector can also be attached at the center, then both connectors are attached at the same height. However, if one connector is attached at one end of the beam (viewed along its length), and the other connector is attached at the opposite end, then the two connectors are not attached at the same height but are offset from each other. The decisive factor is the position of the bolts used for attachment.If the bolts used to attach a first connector to a beam are completely offset from the bolts used to attach a second connector to the beam, then the two connectors are not attached to the beam at the same height. Otherwise, the two connectors are attached to the beam at the same height.

[0013] The first connector can be attached to the support by several first bolts.

[0014] The second connector can be attached to the support by several second bolts, whereby the second connector is then not attached to the support by the first bolts.

[0015] This allows for the initial attachment of a first connector to the beam using bolts, followed by the attachment of a second connector at the same height. This enables flexible installation. If needed, a second connector can be attached at a later time, in addition to the already attached first connector, without having to remove the first bolts. Therefore, the support structure can be flexibly installed with minimal effort.

[0016] The first connector is also attached to the support by the second bolts. This provides additional stabilization without increasing the assembly effort.

[0017] The system can include a third connector, which can also be attached to the beam at the same height using one or more third bolts, rather than the first and second bolts. This allows for the initial attachment of a first connector and, optionally, a second connector to the beam at the same height, followed by the attachment of a third connector at the same height. This further improves the system's flexibility in installation without requiring additional effort. If needed, a third connector can be attached to the beam at a later time, in addition to the first and optional second connector, without having to loosen the first and / or second bolts.

[0018] The one or more third bolts can also attach the first and / or second connector to the support. This provides additional stabilization without increasing the assembly effort.

[0019] The beam can have two profile elements, which are connected to each other. In cross-section, the profile elements can be, for example, T-shaped or U-shaped. However, other shapes are also possible. For reasons of stability and weight, a U-shape is preferable.

[0020] A gap may exist between the two profile elements. The first connector can encompass a first wall section that extends into the gap between the profile elements. This first wall section of the first connector can be attached to the beam using first bolts, and / or second bolts, and / or third bolts. The first connector can also encompass a second wall section that extends into the gap between the profile elements. This second wall section of the first connector can be attached to the beam using first bolts, and / or second bolts, and / or third bolts.

[0021] If the first connector encompasses the aforementioned first wall section and the aforementioned second wall section, a gap can remain between the two wall sections. This creates a receiving space into which, for example, a leg or a differently shaped wall section of a second connector can be inserted. The second connector can include a first wall section that extends into the gap between the two wall sections of the first connector, i.e., into the receiving space. This first wall section of the second connector can be attached to the beam using second and / or third bolts. Such a wall section, extending into the receiving space of the first connector, provides stability advantages without requiring excessively large installation space or material.

[0022] The second connector can include a second wall section that extends into the space between the two wall sections of the first connector, i.e., into the receiving space. This second wall section of the second connector can be attached to the beam using second bolts and / or third bolts.

[0023] The second connector can include a first leg that extends into the space between the two wall sections of the first connector, preferably with minimal play, to facilitate easy insertion of the leg and to provide stability advantages in the event of excessively high loads. This first leg of the second connector can be attached to the beam using second and / or third bolts.

[0024] The second connector can include a second leg that extends into the space between the two wall sections of the first connector, preferably with minimal play for the reasons mentioned above. This second leg of the second connector can be attached to the beam using second and / or third bolts. Providing two legs further improves stability.

[0025] The first connector can include a first pocket. In this case, there are not only two wall sections that provide a receiving space, but also additional components such as tabs that further define the receiving space. For example, there can be a tab that limits the receiving space at one end. Two tabs can be provided, creating a pocket-like opening and thus further defining the receiving space. During assembly, a leg or wall section can only be inserted through this pocket-like opening to access the receiving space of the first connector. The first pocket can encompass the aforementioned first wall section of the first connector and the aforementioned second wall section of the first connector. The first wall section or the first leg of the second connector can extend into the first pocket.Since this determines the relative position between the first connector and the second connector when both connectors are to be mounted at the same height, assembly delays can be better avoided.

[0026] The first connector can include a second pocket. The second pocket can encompass both the aforementioned first wall section of the first connector and the aforementioned second wall section of the first connector. The second wall section or the second leg of the second connector can extend into the first pocket. This allows for further improved stability and avoids delays during assembly.

[0027] Each connector can be positioned at the same height on a different side of the beam. Connectors can be mounted sequentially on different sides without having to loosen previously installed bolts. It is possible to first attach the first connector to the beam on one side using the first set of bolts. Then, at the same height, the second connector can be attached to the opposite side of the beam using the second set of bolts, without having to remove the first set of bolts. Following this, at the same height, the third connector can be attached laterally, and thus to a third side, using the third set of bolts, without having to remove the first and second set of bolts. Attaching the second connector is not necessary to attach the third connector.Therefore, the first connector can be attached to the support using the first bolts, and subsequently the third connector can be attached using the third bolts, without having to loosen the first bolts.

[0028] If the first and second connectors are attached to opposite sides of the beam, they typically form an angle of 180°. If a third connector is attached to the side of the first connector, they typically form an angle of 90°.

[0029] Connectors can therefore form a 180° angle with each other in one configuration. Connectors can also form a 90° angle with each other.

[0030] Each connector can be connected to at least one strut.

[0031] The profile elements of a beam can have a U-shaped cross-section. The base of one U-shaped cross-section can be connected to the base of another, for example, by one or more bolts. These bolts can pass through sleeves that act as spacers for the profile elements. The sleeves then create a gap between the base of one U-shaped cross-section and the base of the other, thus providing a space between the two profile elements. Alternatively, the profile elements of the beam can be connected using plates. Welded joints can be used between the plates and the profile elements to attach the plates to the profile elements. Alternatively, the ends of bolts can be welded to the profile elements.

[0032] The support can comprise three parallel rows of holes, hereinafter referred to as the first, second, and third rows. The second row is located between the first and third rows. Each row of holes in the support comprises a plurality of holes. In particular, each row comprises at least five holes, preferably at least ten holes, and most preferably at least 20 holes. Each row of holes is particularly straight. Holes can be round or oblong. The holes in the first and third rows are preferably exclusively round to facilitate assembly. The second row, i.e., the middle row, preferably comprises both round and oblong holes to facilitate assembly. Round and oblong holes advantageously alternate in the middle row. For example, exactly one oblong hole can follow exactly one round hole, and so on.The holes in a row are advantageously spaced equally apart. The holes in the first and third rows are advantageously located at exactly the same height. The holes in the middle row are advantageously offset relative to the holes in the first and third rows.

[0033] The first connector can have three parallel rows of holes, referred to below as the first, second, and third rows. The second row is located between the first and third rows. Each row of holes in the first connector contains a plurality of holes. The middle row, i.e., the second row, may contain only two holes. However, the second row may also contain more than two holes. The other two rows generally contain more than two holes, for example, six or eight holes. Each row of holes is, in particular, straight. Holes can be round or oblong. However, the holes in the first, second, and third rows are preferably exclusively round holes to facilitate assembly. The holes in each row are advantageously spaced equally.The holes in the first and third rows are advantageously located at exactly the same height. The holes in the middle row are advantageously offset relative to the holes in the first and third rows. The holes are arranged, in particular, so that they align with the holes in the three rows of a beam, allowing bolts to be inserted through the holes in the beam and through the holes in the first connector. Preferably, in the assembled state, all the holes in the three rows of the first connector align with the holes in the three rows of the beam, so that, in the assembled state, bolts can be inserted through all the holes in the three rows of the first connector.

[0034] A first bolt can pass through a hole in the first row of beams and first connectors to attach the first connector to the beam. A first bolt can pass through a hole in the second row of beams and first connectors to attach the first connector to the beam. A first bolt can pass through a hole in the third row of beams and first connectors to attach the first connector to the beam.

[0035] The second connector can have two or three parallel rows of holes, which are hereinafter referred to as the first row, second row, and, if applicable, third row. The second row of holes can be located between the first and the third row, if present. Each row of holes in the second connector comprises a plurality of holes. A second row of holes can have only two holes, but it can also have more than two. The one or two further rows of holes generally have more than two holes, for example, four or six holes. Each row of holes runs in a straight line. Holes can be round or oblong. However, the holes in the first, second, and, if applicable, third row of holes are preferably exclusively round holes to facilitate assembly. The holes in each row are advantageously always spaced equally apart. The holes in the first and, if applicable, third rows are...The existing third row of holes is advantageously located at precisely the same height. The holes of the second row are advantageously offset relative to the holes of the first row. In particular, the holes are arranged so that they can align with the holes of two or three rows of holes in a beam, allowing bolts to be inserted through the holes of the beam and through the holes of the second connector. Preferably, in the assembled state, all holes of the two or three rows of holes in the second connector align with holes of two or three rows of holes in the beam, so that, in the assembled state, bolts can be inserted through all holes of the two or three rows of holes in the second connector.

[0036] A second bolt can pass through a hole in the first row of holes between the beam and the second connector to fasten the second connector to the beam. Preferably, the first connector is also fastened to the beam by the second bolt. A second bolt can pass through a hole in the second row of holes between the beam and the second connector to fasten the second connector to the beam. Preferably, the first connector is also fastened to the beam by means of the second bolt. A second bolt can pass through a hole in the third row of holes between the beam and the second connector to fasten the second connector to the beam. Preferably, the first connector is also fastened to the beam by means of the second bolt.

[0037] A support arrangement according to the preceding claim, characterized in that the second or third connector forms an angle of 90° with the first connector, and / or that the second or third connector is connected to the support by a bolt that passes through a hole in the second middle row of holes.

[0038] The first, second, and / or third connector can be attached to two beams in one configuration when assembled. A connector can therefore serve to firmly connect beams to each other and also beams to struts. Since multiple connectors can be connected to two beams when assembled, beams can be mechanically connected to each other with very high stability. The assembly effort required is minimal. If a first connector is inserted with some play into the space between two beams and a second connector is inserted with some play into a space between the first beam, assembly can be carried out with minimal force. Nevertheless, additional safety measures are in place to ensure that the structure can withstand even excessively high loads at all times.

[0039] An inventive system can advantageously comprise two supports of different dimensions, wherein the width of the gap between them is always the same for each support. This makes it possible to insert accessories such as connectors into each gap without having to use accessories of different dimensions. This is particularly true if the first and third rows of holes in the support have the same distance to the adjacent outer surface. The holes in the first and third rows also advantageously have equal spacing between them, regardless of the other dimensions of each support. The holes can then always be used to fasten accessories without having to ensure different hole spacings for the accessories.Alternatively, the accessories can also include holes arranged in such a way that some of these holes correspond to the holes of a first support, or other parts correspond to the holes of a second support of different dimensions. Providing a system with such differently dimensioned supports, but with equally wide gaps between them, comprising one or more accessories that can be inserted into the gaps and attached to the supports, for example, by means of bolts, independently solves the problem at hand and is a separate invention. This separate invention can be combined with the features of the invention described so far.

[0040] They show Figure 1: Beam with two profile elements; Figure 2: Sectional view through a beam; Figure 3: Sectional view through a beam; Figure 4: Side view of a first connector; Figure 5: Section through a first connector; Figure 6: Beam with a first connector attached; Figure 7: Side view of a second connector; Figure 8: Section through a second connector; Figure 9: Connector with two beams; Figure 10: Beam with first and second connectors; Figure 11: Side view of a third connector; Figure 12: Sectional view of the third connector; Figure 13: Top view of the third connector; Figure 14: Beam with first, second, and third connectors; Figure 15: Beam with third connector; Figure 16: Second embodiment of a first connector with a beam; Figure 17: Second embodiment of a second connector.

[0041] The Figure 1Figure 1 shows a beam 1 with two profile elements 2 and 3. The profile elements 2 and 3 of the beam have a U-shaped cross-section. Each cross-section thus has a base 4 and two legs 5 extending from the base. Viewed from the base 4, the legs 5 have, as shown in the figure 3, a U-shape. Figure 1Shown facing outwards. The base 4 of profile element 2 is connected to the base 4 of the other profile element 3 by bolts 6. These bolts 6 pass through sleeves 7, which serve as spacers. The sleeves 7 ensure a gap between the base 4 of one profile element 2 and the base of the other profile element 3. This creates a space 8 between the two profile elements 2 and 3. The bolts 6 can have a thread at one end onto which a nut is screwed and a head at the other end to act as a fastening element. However, it is also possible to weld the ends of each bolt 6 to the respective base 4. In this case, sleeves 7 are not required to create a gap. Therefore, sleeves 7 are not strictly necessary to create a gap between the two profile elements 2 and 3.

[0042] Each profile element 4 comprises three parallel and straight rows of holes 9, 10, and 11. The second row of holes 10 runs between the first row 9 and the third row 11. The holes in the three rows are round. Each row 9, 10, and 11 has more than ten holes. For assembly reasons, the first row 9 and the third row 11 have more holes than the second row 10. The holes in the first and third rows 9 and 11 are arranged at the same height. In contrast, the holes in the second row 10 are offset to facilitate assembly. The diameter of the holes in the second row 10 is advantageously larger than the diameter of the holes in the first row 9 and the third row 11. The diameters of the holes in the first row 9 and the third row 11 are advantageously the same.

[0043] The bolts 6 can, for example, be passed through holes of the first rows of holes 9 and through holes of the third rows of holes 11 in order to connect the two profile elements 2 and 3 stably without having to use an excessive number of bolts 6.

[0044] In order to be able to provide beam 1 for different load situations, the profile elements 2 and 3 can be dimensioned differently from beam to beam.

[0045] However, the distances between base 4 of one profile element 2 and base 4 of the other profile element 3 do not differ advantageously. Examples with dimensions are shown in the section below. Figures 2 and 3 shown. The gap between each beam is therefore the same width, regardless of the other dimensions of each beam. For example, the width of the gap as shown in the Figures 2 and 3The dimension of each beam is shown as 64 mm. However, the dimension of a first beam can differ from the dimension of a second beam, for example, due to the distances between the two legs of each U-shaped cross-section. Thus, the distance between the two legs of a U-shaped cross-section in a first beam can be as shown in the Figure 2 The distance shown is 120 mm. The spacing for a second support can be between the legs of a U-shaped cross-section as shown in the... Figure 3 The distance shown is 200 mm to provide differently dimensioned beams for different load situations. The distance between the outer ends of the legs of U-shaped profile elements can be, for a first beam, as shown in the Figure 2 The distance between the outer ends of the legs of U-shaped profile elements can be 172 mm, as shown in the diagram. Figure 3 shown to be 214 mm.

[0046] The Figure 4 shows a side view of a first connector 12. Figure 5 shows a section view rotated by 90° through the first connector 12.

[0047] The first in the Figures 4 and 5The connector 12 shown comprises two side walls 13. The two side walls 13 are spaced apart, leaving a gap 14 between them. The two side walls 13 are connected to each other 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 opposite the opening 16. This straight, strip-shaped tab 17 also connects the two side walls 13 and is attached to them by welds. The straight tab 17 forms the base of a pocket. A leg of a second connector can be inserted through the opening 16. The leg of the second connector can be chosen to be long enough to rest on the strip-shaped tab 17.One leg of a second connector can also be so long that it does not reach the bottom or the holes of the first row 19. The cross-section of one leg of a second connector is advantageously adapted to the opening 16 so that the leg can be inserted into the opening 16 with minimal play. If, for example, the second connector is subjected to excessive stress in the assembled state and bends as a result, additional stabilization is then available, for example, from the side walls 13.

[0048] The side walls 13 widen towards the bottom, as shown in the Figure 4The widened section 18 of the side walls 13 prevents the first connector 12 from being pushed through two profile elements 2, 3 of a beam 1. The other, non-widened section of the first connector 12 can be inserted into the space between two profile elements 2, 3 of a beam 1 on one side. In order to connect the inserted, non-widened section of the first connector 12 to the beam with bolts, this non-widened section has a total of three rows of holes 19, 20, 21. The first row of holes 19 comprises six round holes and 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 diameters of the holes in the middle row of holes 20 are larger than the diameters of the holes in the other two rows of holes 19 and 21.The holes of the middle row 20 are offset relative to the holes of the other two rows 19 and 21. The distance between the holes of each row 19 and 21 is always the same. The holes of the first and third rows 19 and 21 are arranged at the same height relative to each other. The holes of each row 19, 20, 21 run in a straight line. The rows 19, 20, 21 are arranged such that bolts can be inserted through the holes of the rows 19, 20, 21 and simultaneously through the holes of the rows 9, 10, and 11 of the profile elements 2 and 3, provided that the first connector 12, with its designated, unwidened section, has been appropriately inserted into the space of the support one. The widened section 18 includes one or more holes 22, for example, three holes, which serve to fasten struts.For stabilization, the widened area 18 can include one or more cross plates 23, which can be connected to side walls 13 by welded connections.

[0049] The Figure 6Figure 1 shows a first connector 16 attached to a beam 1. The first connector 16 is fastened to one end of the beam 1 by means of two first bolts 24. One first bolt 24 is inserted through two opposing holes in row 9 of the beam 1 and through two corresponding, opposing holes in row 19 of the first connector 16. Another first bolt 24 is inserted through two opposing holes in row 11 of the beam 1 and through two corresponding, opposing holes in row 21 of the first connector 16. The bolts 24 may have a head on one side that prevents them from being fully inserted through the holes in rows 9 and 11 of the beam 1. On the opposite side, the bolts may have a bore through which a cotter pin is inserted.Each cotter pin then prevents the bolts 24 from being pulled out again. The first connector 16 is then properly attached to the support 1.

[0050] The first connector 16 could also have been inserted into the space between the beam 1 at another location and attached to the beam 1 with first bolts 24.

[0051] The Figure 7 shows a side view of a second connector 25. Figure 8 shows a section view rotated by 90° through the second connector 25. The second in the Figures 7 and 8The connector 25 shown comprises two side walls 26. The two side walls 26 are spaced apart from each other, leaving a gap 27 between them. The two side walls 26 are connected to each other 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 shown in section as in the Figure 7 shown in a U-shape. The widening 29 can be reinforced by one or more welded-in plates 30.

[0052] The widening 29 prevents the second connector 25 from being pushed through two profile elements 2, 3 of a support 1 or through side walls 13 of a first connector 12. The other, non-widened section of the second connector 25 can be inserted into the opening 16 of the first connector 12. In order to connect the inserted, non-widened section of the second connector 25 to the support 1 by means of two bolts, this non-widened section, 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 such that second bolts can be inserted through holes in rows 31 and 32 and simultaneously through holes in rows 10 and 11 of profile elements 2 and 3, provided the second connector 25, with its designated, unwidened section, has been appropriately inserted into the space between the beams 1 and 3. The first row of holes 32 comprises four round holes equidistant from each other. The second row of holes 31 comprises two round holes. The holes in the second row of holes 31 are offset from those 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.

[0053] The widening 29 includes one or more holes 33, which serve to fasten struts.

[0054] The Figure 9Figure 1 shows two beams 1 that are firmly connected to each other by a first connector 12. The second connector 25 is shown as in the diagram. Figures 7 and 8 shown dimensioned such that its leg, formed by the side walls 26, cannot reach the bottom 17 of the pocket of the first connector 12, nor can it reach the [unclear] in the Figure 6 In the lower rows of holes 9 and 19 shown, all 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 using first bolts 24. In the Figure 9It is shown that, for example, a total of eight first bolts 24 can be present to fasten the two beams 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 beam, as indicated by an arrow, until further insertion is finally prevented by the widening 29.

[0055] If the second connector 25 has been inserted into the opening 16 of the first connector 12 to the maximum possible extent, the second connector 25 can then be fastened to the two supports 1 using second bolts 34, as shown in the Figure 10The bolts 34 are inserted through holes in the upper row of holes 11 of the two beams 1. These bolts 34 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. Thus, these bolts 34 not only fasten the second connector 25 to the two beams 1, but also the first connector 12. The additional loads, which can occur, for example, due to struts attached to the second connector 25, can be compensated for by inserting one leg of the second connector 25 into the space between the two beams 1. Since the leg of the second connector 25 is inserted with some play, this leg only provides stabilization under excessive load.

[0056] The Figure 11 shows a side view of a third connector 35. Figure 12Figure 3 shows a section view rotated by 90° through the third connector 35. Figure 13 shows a top view of the third connector 35.

[0057] 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 side walls 37. The two side walls 37 are spaced apart from each other, leaving a gap 38 between them. The U-profile is reinforced by one or more welded-on plates 39, which are arranged, among other places, on the end faces.

[0058] The base 36 contains two holes 40. The side walls 37 have, for example, one, two, or three holes 41, which serve to fasten struts. The diameter of the holes 40 corresponds to the diameter of the aforementioned rows of holes in the beam and the first and second connectors, which include the holes with the larger diameter.

[0059] Using third bolts, the third connector 35 can be connected to the two supports 1 as shown in the Figure 14 The two third bolts are shown connected. They pass through the two pairs of holes in the middle rows of holes 10 of the two beams 1, which are located at the edges of the ends of the beams 1 in the Figure 10 are not yet occupied. These third bolts also additionally fasten the first connector 12 and the second connector 25 to the beams 1. Although the load increases due to the large number of connectors 12, 25, 35 and the components attached to them in the Figure 14 The attached struts 42 are also shown. However, this highly stressed point in a supporting structure is further reinforced by the additional bolts and connectors. The struts 42 can extend their ends into the corresponding spaces between the connectors 12, 25, 35 for attachment to the connectors 12, 25, 35, and then be fastened to the connectors by means of bolts 43 as shown.

[0060] In the Figure 14 Although only one third connector 35 is shown, another third connector 35 can also be attached at the same height, specifically on the back of the one shown in the diagram. Figure 14 The carrier shown, 1, with the third bolts, with which the one already in the Figure 14 The third support 35 shown is attached. Is there another third connector 35 on the back of the one shown in the Figure 14 If the support 1 shown is attached to the support 1 by third bolts, then one or more struts 42 can also be attached to this further third support 35.

[0061] The struts 42 can be rigid or length-adjustable. Length-adjustable struts are advantageous for allowing for variable assembly of the supporting structure.

[0062] However, a connector can also have a different component attached to it instead of a strut, such as a strap or an adapter. Furthermore, a connector attached to support 1 can be rigidly connected to another connector instead of a strut, which in turn can be attached to yet another support.

[0063] In the Figure 14 The diagram shows the case where the connectors are attached at a joint between two beams. However, the connectors can also be attached to beam 1 away from the joint and thus away from both ends of the beam, but in the same way.

[0064] The Figure 15Figure 1 further illustrates the attachment of the third connector 35 to a support 1 using third bolts 44, which pass through holes in the middle row of holes 10. A cotter pin 45 with a pivotally connected retaining ring 46 is also shown. The cotter pin 45 is inserted through a hole in the bolt 44, and the retaining ring 46 is folded over the end of the bolt 44 to secure the position of the cotter pin 45. The third connector 45 is then attached to the support 1. Figure 15 This clarifies that the third connector 35 can be attached to the beam 1 independently of the other two connectors 12 and 25. Similarly, the second connector 25 can also be attached to a beam 1 independently of the other connectors 12 and 35.

[0065] However, two third connectors can also be attached to the support at the same height, opposite each other.

[0066] The Figure 16Figure 1 shows another embodiment for a first connector 12. This embodiment differs from the first connector 12 already shown in that it provides two openings 16 through which two legs of a second connector can be inserted. The two openings 16 are provided by a welded-in sheet 47 between the two openings 16. In addition, there are welded-in sheets 48 at the edges to form the two openings. Figure 16 This illustrates that a large number of bolts 49 can be used immediately to connect the first connector 12 to a support 1. However, this is generally not practical, as bolts 49 would then have to be loosened again to add a second connector 25. This in Figure 16 The illustrated embodiment shows a support 1 in which the middle row of holes 10 alternately comprises round holes and elongated holes.

[0067] Comparable to the Figure 8shows the Figure 17 a sectional view through a second embodiment of a second connector 25, which differs from the one in the Figure 8 The embodiment shown comprises two legs. The two legs are formed by side walls 26, which are opposite each other in pairs and are laterally connected to each other by welded-on plates 50. These legs are inserted into the two openings of the [unclear text]. Figure 16 The first connector 12 shown is inserted to attach this second connector 25 to a support in addition to the first connector 12. In contrast to the embodiment of a second connector shown in Figure 8, the connector according to the Figure 17There is also a lower row of holes 51, for a total of three rows of holes 32, 31, and 51. For fastening to a support 1, second bolts are inserted through these holes 51 and then through the corresponding holes of a lower row of holes on the support(s) 1 and on the associated first connector 12. The upper row of holes 32 and the lower row of holes 31 each consist of four holes arranged along a straight line. The middle row of holes 31 includes two holes with a larger diameter compared to the holes in the upper row of holes 32 and the lower row of holes 51. The two holes in the middle row of holes 31 are offset relative to the holes in 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.
