Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a truss installation anti-lateral bending structure. Background Technology

[0002] A truss is a supporting beam structure made up of members connected by welding, riveting, or bolting. It is usually a planar or spatial structure with triangular units. The advantages of trusses are that the members mainly bear tension or compression, which can make full use of the material, save materials, and reduce the weight of the structure. Common types include steel trusses, reinforced concrete trusses, prestressed concrete trusses, timber trusses, steel and timber composite trusses, and steel and concrete composite trusses. A space frame structure is a spatial structure made up of multiple members connected by nodes in a certain grid pattern. It has the advantages of low spatial stress, light weight, high stiffness, and good seismic performance. It can be used as the roof of buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, aircraft hangars, and workshops with large two-way column spacing. The disadvantage is that there are more members converging at the nodes, and the fabrication and installation are more complex than planar structures.

[0003] However, since trusses are triangular structures and are mostly made of rigid materials combined and welded together, the materials are prone to displacement and tilting during assembly. Therefore, trusses require assistance during installation. However, when working at heights or on a small work surface, they are often operated by one person. The rigid materials are prone to displacement, resulting in tilted installation that is not in place, thus affecting aesthetics and structural safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a truss installation anti-lateral bending structure to solve the problems of insufficient friction between materials during truss installation, which can easily lead to separation or tilting, requiring human assistance, and causing rigid materials to easily shift when operating at heights or on small work surfaces, resulting in tilted installation and affecting aesthetics and structural safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a truss installation anti-lateral bending structure, comprising a vertical H-shaped steel beam assembly, a Bailey panel side rod assembly, reinforcing rib fasteners, and a support column. The vertical H-shaped steel beam assembly and the Bailey panel side rod assembly are welded together. The reinforcing rib fasteners are nested on the top of the support column. The bottom of the vertical H-shaped steel beam assembly is welded to the top of the reinforcing rib fasteners. The combination of the Bailey panel side rod assembly and the reinforcing rib fasteners ensures a stable connection between the vertical H-shaped steel beam assembly and the support column.

[0006] Preferably, the vertical H-shaped steel beam assembly includes vertical steel beam columns, T-shaped reinforcing ribs, and rear support rods. The rear support rods are welded at a 60-degree angle to the rear side of the vertical steel beam columns. Two T-shaped reinforcing ribs are provided and welded to the left and right sides of the vertical steel beam columns respectively. Reinforcing rib fasteners are welded to the bottom of the vertical steel beam columns.

[0007] The T-shaped reinforcing plates wrapped around the vertical steel beams and columns can stabilize the top of the truss during installation, preventing lateral bending and allowing it to withstand the load of lateral stress.

[0008] Preferably, the Bailey panel side rod assembly includes a chord and a tensioned truss seat. The chord is inclined at 30 degrees and welded to the tensioned truss seat. There are two tensioned truss seats, which are welded to the left and right sides of the H-beam assembly, respectively.

[0009] The chord members and tensioned truss seats can stabilize the individual inclined truss members against lateral bending, allowing the tilting stress to be transmitted to the seat surface.

[0010] Preferably, the reinforcing rib fastener has a cover plate, a C-shaped reinforcing rib plate, a bottom frame, and a snap-fit ​​rib strip. C-shaped reinforcing rib plates are welded to the left and right sides between the cover plate and the bottom frame. The C-shaped reinforcing rib plates are fastened together with the snap-fit ​​rib strips. A vertical H-shaped steel beam assembly is welded to the top of the cover plate.

[0011] The truss, which is connected to the bottom column by C-shaped reinforcing plates and interlocking ribs, is stabilized to prevent lateral bending, allowing it to withstand lateral stress.

[0012] Preferably, the bottom end of the H-shaped steel beam assembly is horizontally cross-welded with a first H-shaped crossbeam and a second H-shaped crossbeam.

[0013] The intersection of the first H-shaped beam and the second H-shaped beam can be used to locate the points where the truss is installed at the column ends for secure welding operations.

[0014] Preferably, the chord members and tensioned truss seats are provided in two or more and are combined in a square frame structure to form a Bailey truss.

[0015] By combining chord members with tensioned truss seats to form a Bailey truss structure, the anti-bending load-bearing frame receives complete stress support and load dissipation effect.

[0016] This utility model provides a truss installation anti-lateral bending structure, which has the following beneficial effects:

[0017] This type of truss installation anti-lateral bending structure, when workers are welding and assembling the truss, the anti-lateral bending structure can prevent the overall frame structure from being supported by the chords of the Bailey panel side members and the T-shaped reinforcing plates of the tensioned truss seat when welding the vertical H-shaped steel beam group. Because of the frame stress effect of the Bailey panel truss, the chords and tensioned truss seats have a combined unloading and stress diffusion stress to stabilize and prevent instability. Thus, when the first H-shaped beam and the second H-shaped beam are fixed at the top of the support column, the secondary anti-lateral bending truss and column welding operation at the bottom can be carried out by the reinforcing rib fasteners welded and fixed to the bottom of the vertical steel beam column and the rear support. The C-shaped reinforcing plate between the cover plate and the bottom frame is used to fasten the ribs, forming a truss connection end enclosure and load-bearing coefficient that can stabilize the load.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5This utility model provides a truss installation anti-lateral bending structure, including a vertical H-shaped steel beam assembly 1, a Bailey panel side rod assembly 2, a reinforcing rib fastener 5, and a support column 6. The vertical H-shaped steel beam assembly 1 and the Bailey panel side rod assembly 2 are welded together. The reinforcing rib fastener 5 is nested on the top of the support column 6. The bottom of the vertical H-shaped steel beam assembly 1 is welded to the top of the reinforcing rib fastener 5. The combination of the Bailey panel side rod assembly 2 and the reinforcing rib fastener 5 ensures that the vertical H-shaped steel beam assembly 1 is securely installed with the support column 6.

[0026] The vertical H-shaped steel beam assembly 1 is provided with a vertical steel beam column 11, a T-shaped reinforcing rib plate 12, and a rear support rod 13. The rear support rod 13 is welded at a 60-degree angle to the rear side of the vertical steel beam column 11. Two T-shaped reinforcing rib plates 12 are provided and welded to the left and right sides of the vertical steel beam column 11 respectively. A reinforcing rib fastener 5 is welded to the bottom of the vertical steel beam column 11.

[0027] It should be noted that the T-shaped reinforcing plates 12 wrapped around the vertical steel beams and columns 11 can stabilize the top of the truss during installation and prevent lateral bending, allowing the lateral stress to withstand the load.

[0028] The Bailey panel side rod group 2 is provided with a chord 21 and a tensioned truss seat 22. The chord 21 is inclined at 30 degrees and welded together with the tensioned truss seat 22. There are two tensioned truss seats 22, which are respectively welded to the left and right sides of the H-shaped steel beam group 1.

[0029] It should be noted that the chord 21 and the tension truss seat 22 can stabilize the single inclined truss member against lateral bending, allowing the tilting stress to be transmitted to the seat surface.

[0030] The reinforcing rib fastener 5 is provided with a cover plate 51, a C-shaped reinforcing rib plate 52, a bottom frame 53, and a snap-fit ​​rib 54. The left and right sides between the cover plate 51 and the bottom frame 53 are welded with C-shaped reinforcing rib plates 52. The C-shaped reinforcing rib plates 52 and the snap-fit ​​rib 54 are fastened together. A vertical H-shaped steel beam group 1 is welded to the top of the cover plate 51.

[0031] It should be noted that the truss, which is connected to the bottom column by the C-shaped reinforcing rib plate 52 and the interlocking rib strip 54, is stable against lateral bending, so that the lateral stress can withstand the load.

[0032] The bottom end of the H-shaped steel beam group 1 is horizontally cross-welded with a first H-shaped crossbeam 3 and a second H-shaped crossbeam 4.

[0033] It should be noted that the point where the truss is installed at the column end can be located and the welding operation can be carried out by the intersection of the first H-shaped beam 3 and the second H-shaped beam 4.

[0034] The chord members 21 and the tensioned truss base 22 are provided in two or more and are combined in a square frame structure to form a Bailey truss.

[0035] It should be noted that by combining the chord member 21 with the tensioned truss seat 22 to form a Bailey truss structure, the anti-bending load-bearing frame can obtain complete stress support and load dissipation effect.

[0036] When workers weld and assemble the truss, the anti-bending structure can be achieved by welding the chord 21 of the Bailey side member group 2 and the tensioned truss seat 22 to the T-shaped reinforcing plate 12 of the vertical H-shaped steel beam group 1 together to prevent the lateral bending support of the top truss of the overall frame structure. Because of the frame stress effect of the Bailey truss, the chord 21 and the tensioned truss seat 22 have a combined unloading and stress diffusion stress stabilizing and anti-instability support. Thus, when the first H-shaped beam 3 and the second H-shaped beam 4 are cross-fixed at the top of the support column 6, the secondary anti-bending truss and column welding operation at the bottom can be carried out by welding the reinforcing fastener 5 at the bottom of the vertical steel beam column 11 and the rear support 13. The C-shaped reinforcing plate 52 between the cover plate 51 and the bottom frame 53 is connected to the interlocking reinforcing bar 54 to form a truss connection end enclosure and load-bearing coefficient that can stabilize the load.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
