[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Referring to Figure 1 An embodiment provided by the present application: a single-web steel pipe angle truss, comprising a steel pipe 1 as a core support component of the truss, providing main axial bearing capacity, the outer wall of the steel pipe 1 is provided with a plurality of V-shaped web bars 2, which mainly serve to enhance the lateral stability of the truss and prevent the steel pipe 1 from deforming laterally when subjected to stress, the end of each of the plurality of V-shaped web bars 2 is fixedly connected with an angle bar 3, the angle bar 3 serves to connect and transfer force, transferring the force borne by the V-shaped web bars 2 to the steel pipe 1, wherein the plurality of angle bars 3 are arranged in a straight line and fixedly connected to the outer wall of the steel pipe 1, the outer wall of the angle bar 3 on one side is fixedly connected with a longitudinal bar 1 4, and the outer wall of the angle bar 3 on the other side is fixedly connected with a longitudinal bar 2 5, the longitudinal bar 1 4 and the longitudinal bar 2 5 are horizontally symmetrical, the steel pipe 1, the longitudinal bar 1 4 and the longitudinal bar 2 5 form a triangular symmetry, which can effectively disperse load and enhance the overall stability of the truss, the steel pipe 1, the longitudinal bar 1 4 and the longitudinal bar 2 5 are connected through the plurality of angle bars 3, and the plurality of angle bars 3 and the plurality of V-shaped web bars 2 are integrally bent and formed.

[0027] Specifically, the truss structure adopts a variety of components firmly connected together by resistance welding technology, ensuring the overall stability and strength of the structure. Specifically, when external loads act on the truss structure, the loads are first transmitted to the longitudinal bar one 4 and the longitudinal bar two 5 through the consolidation layer 7. The consolidation layer 7, as part of the structure, not only plays a role in isolation and protection, but also effectively transmits external loads, ensuring that the entire structure is uniformly stressed. The longitudinal bar one 4 and the longitudinal bar two 5 are important load-bearing components in the truss structure. They are connected with the steel wire mesh 6, which disperses and transmits the load, effectively preventing the concentration of local stress. The steel wire mesh 6 plays a role in enhancing the tensile and shear capacity, making the entire truss structure more stable when bearing external loads. Then, the longitudinal bar one 4 and the longitudinal bar two 5 transmit the load to the corner bar 3. The design of the corner bar 3 is crucial, as its arrangement is linear, which not only improves the mechanical properties of the structure, but also ensures the uniformity of load transmission. Multiple corner bars 3 are connected to each other and to the steel pipe 1. Through the corner bar 3, the load is effectively transmitted to the steel pipe 1. The steel pipe 1, as the main load-bearing component of the truss structure, bears the load transmitted by the corner bar 3 and transmits it along the axial direction of the steel pipe to other components. In order to prevent the steel pipe 1 from bending or losing stability when bearing loads, the V-shaped web bar 2 plays a crucial stabilizing role. The V-shaped web bar 2 provides multiple-point support for the steel pipe 1 by connecting with the steel pipe 1, effectively limiting the lateral displacement of the steel pipe under axial load. The design of the V-shaped web bar 2 not only increases the stability of the truss structure, but also improves the stress distribution, enabling the steel pipe 1 to remain stable under larger loads. Multiple V-shaped web bars 2 and corner bars 3 form a complete lateral support system, ensuring the stability of the entire structure when bearing transverse loads and effectively preventing the truss structure from losing stability.

[0028] With reference to Figure 2 and Figure 3 , the truss can pre-bury the longitudinal bar one 4 and the longitudinal bar two 5 at the bottom corner inside the consolidation layer 7 when in use. The truss can connect the longitudinal bar one 4 and the longitudinal bar two 5 with the steel wire mesh 6 by resistance welding to form when in use. The steel wire mesh 6 is pre-buried inside the consolidation layer 7. The steel wire mesh 6 can enhance the tensile strength of the consolidation layer 7 and prevent cracks in the consolidation layer 7 when stressed. The connection between the steel wire mesh 6, the consolidation layer 7, and the truss forms the overall framework of the floor slab.

[0029] Specifically, the combination of the steel wire mesh 6 and the concrete layer 7 further enhances the overall load-bearing capacity of the truss, the design of the concrete layer floor slab can be directly connected with the building structure without additional floor removal, greatly simplifying the construction process, the pouring of the concrete layer 7 not only enhances the durability of the structure, but also plays a role in fireproofing and corrosion prevention, effectively prolonging the service life of the truss structure, in this way, the truss structure not only can provide excellent load-bearing capacity, but also can reduce the workload of later maintenance, and reduce the overall cost of the building.

[0030] Working principle: first, all the components of the truss structure are firmly connected together by resistance welding, when external load acts on the truss structure, the load is first transmitted to the longitudinal bar one 4 and the longitudinal bar two 5 through the concrete layer 7, since the longitudinal bar one 4 and the longitudinal bar two 5 are connected with the steel wire mesh 6, the steel wire mesh 6 can help to disperse and transmit the load, prevent local stress concentration from causing structural damage, the longitudinal bar one 4 and the longitudinal bar two 5 transmit the load to the corner bar 3, since the multiple corner bars 3 are arranged in a straight line and connected with the steel pipe 1, the corner bar 3 uniformly transmits the load to the steel pipe 1, the steel pipe 1 as the main load-bearing component, bears the load transmitted by the corner bar 3 and transmits it along the axial direction, in this process, the V-shaped web member 2 plays a role in stabilizing the steel pipe 1, preventing the steel pipe 1 from bending or losing stability laterally when bearing the load, the multiple V-shaped web members 2 and the corner bars 3 form a stable lateral support system, the V-shaped web member 2 provides multiple-point support around the steel pipe 1, effectively limiting the lateral displacement of the steel pipe 1, and by pouring the concrete layer 7 outside the steel wire mesh 6 to form a concrete layer floor slab, it can be directly installed on the building during use, without the need for floor removal, reducing the construction steps and expanding the use range.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included in the protection scope of the present application.
