Description

Technical Field

[0001] The utility model relates to the technical field of steel structure components, and particularly relates to a steel structure truss. Background Art

[0002] A truss is a support beam structure formed by connecting rods through welding, riveting or bolting. The existing Chinese utility model patent with the application number 201820804403.5 discloses a steel structure welded truss, which realizes the stable connection of the truss through welding. However, the welding method has the problem of inconvenient layout of structural assembly. At the same time, once a beam-column bends and breaks after welding, the whole structure has to be replaced, and there is room for improvement. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a steel structure truss with stable structure and convenient disassembly and assembly in view of the deficiencies in the above background art.

[0004] To achieve the above purpose, the utility model provides a steel structure truss, which adopts the following technical scheme:

[0005] A steel structure truss includes at least two groups of longitudinals arranged at intervals. Cross beams are provided at the front end and the rear end between adjacent longitudinals. The longitudinal is in an I shape. Bending parts are arranged at the left and right ends of the upper and lower side walls of the longitudinal in an opposite direction. The cross beam includes a fixing plate. Limiting parts are arranged at both ends of the fixing plate and placed in the space formed by the two bending parts at one end of the longitudinal. Through fixing holes are opened on the bending parts, the limiting parts and the vertical middle plate of the longitudinal. Fixing rods are inserted through the fixing holes, and nuts are screwed at both ends of the fixing rods, and the nuts abut against the outer sides of the bending parts.

[0006] In a further improvement of the steel structure truss of the utility model, protruding parts are further provided on the upper and lower surfaces of the fixing plate, and the protruding parts cooperate with the limiting parts to clamp the bending parts.

[0007] In a further improvement of the steel structure truss of the utility model, gaskets are provided between the protruding parts and the bending parts.

[0008] In a further improvement of the steel structure truss of the utility model, the longitudinal and the bending parts are integrally formed.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The utility model connects the cross beam and the longitudinal through a connection structure, realizing the convenient layout connection of the two while ensuring the connection stability. On the other hand, the bending parts are provided to further ensure the connection problem. At the same time, the longitudinal can be connected to the cross beam on both the left and right sides, which is also beneficial to the layout connection of multiple groups of cross and longitudinal beams.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figure 1 and Figure 2 shown, a steel structure truss includes at least two groups of longitudinally arranged longitudinal beams 1 spaced apart from each other. Cross beams are provided at both the front end and the rear end between adjacent longitudinal beams. The longitudinal beam is in an I-shaped configuration. Bending portions 2 arranged oppositely are provided at the left and right ends of the upper and lower side walls of the longitudinal beam. The longitudinal beam and the bending portion are integrally formed. The cross beam includes a fixing plate 3. Limiting portions 4 are provided at both ends of the fixing plate and are placed in the space formed by the two bending portions at one end of the longitudinal beam. Through holes are opened on the bending portion, the limiting portion, and the vertical middle plate of the longitudinal beam. A fixing rod 5 is passed through the through holes. Nuts 6 are screwed at both ends of the fixing rod, and the nuts abut against the outer side of the bending portion.

[0017] As Figure 3 shown, protruding portions 7 are further provided on the upper and lower surfaces of the fixing plate. The protruding portions cooperate with the limiting portions to clamp the bending portions. A gasket is provided between the protruding portions and the bending portions.

[0018] Furthermore, the fixing plate can be a C-shaped beam, and diagonal braces can be added inside to increase its stability.

[0019] The working principle of the present utility model is as follows: Insert the limiting portion of the cross beam into the space formed by the bending portion of the longitudinal beam from the front or the rear. Then, pass the fixing rod through the limiting portion, the bending portion, and the protruding portion. Selectively arrange gaskets according to the gap between the protruding portion and the bending portion. Then, screw nuts at both ends of the fixing rod so that the cross beam and the longitudinal beam are stably connected to ensure the overall strength.
