Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a thin-walled steel truss with strong load-bearing capacity. Background Technology

[0002] The primary function of steel trusses is to provide structural support and increase the load-bearing capacity of the structure. In building floor construction, steel truss floor slabs effectively combine the steel reinforcement with the concrete, forming a unified load-bearing system. This structural form not only improves the load-bearing capacity and stiffness of the floor slab but also helps reduce construction time and costs.

[0003] As the load-bearing unit of the floor slab, the steel truss can bear and distribute the weight of the building. However, the existing steel trusses are not good at coping with external forces such as earthquakes and wind loads. The steel truss cannot effectively share and transfer the load, which makes the floor slab prone to cracks due to excessive local loads, thus affecting the overall strength of the floor slab. Utility Model Content

[0004] This application provides a thin-walled steel truss with high load-bearing capacity, solving the problem that in the prior art, steel trusses, as load-bearing units of floor slabs, are unable to effectively bear and distribute the weight of the building. Existing steel trusses are also inadequate in handling external forces such as earthquakes and wind loads, and cannot effectively distribute and transfer loads, leading to floor slabs being prone to cracking due to excessive local loads. This application achieves effective load distribution and transfer, improving the ability to withstand earthquakes and wind loads, preventing floor slabs from cracking due to excessive local loads, and ensuring that the overall strength of the floor slab is not affected.

[0005] This application provides a thin-walled steel truss with high load-bearing capacity, including a fixing component. The fixing component includes an upper chord steel bar, longitudinal bars, transverse bars, web bars, and a lower chord steel bar. The longitudinal bars and transverse bars are located at the bottom of the web bars, and the upper chord steel bar and the lower chord steel bar are fixed on the web bars.

[0006] It also includes a load-bearing component, which is provided in multiples and is located on the upper side of the mesh formed by the longitudinal and transverse ribs;

[0015] Furthermore, the bottom of the abdominal rib is parallel to the plane formed by the longitudinal and transverse ribs;

[0016] The diameter of the abdominal ribs is greater than the diameter of the longitudinal and transverse ribs.

[0017] Furthermore, the lower chord reinforcement is located on the upper side of the web reinforcement, and the lower chord reinforcement is welded and fixed at the bottom bend of the web reinforcement;

[0018] The upper chord steel bar is welded and fixed at the top bend of the web reinforcement.

The fixing component 100 includes an upper chord steel bar 101, longitudinal bars 102, transverse bars 103, web bars 104, and a lower chord steel bar 105. The longitudinal bars 102 and transverse bars 103 are located at the bottom of the web bars 104, forming a steel mesh.

The upper chord steel bar 101 and lower chord steel bar 105 are fixed on the web bars 104, and the upper chord steel bar 101 and lower chord steel bar 105 are parallel to each other. The application also includes load-bearing components 200, of which multiple load-bearing components 200 are provided.

The load-bearing component 200 can disperse the external force on the floor slab. The load-bearing component 200 includes a right support rod 201, a fixing block 202, a fixing seat 204, and a left support rod 205. The right support rod 201 and the left support rod 205 are fixedly connected to both sides of the fixing block 202, respectively. The upper ends of the right support rod 201 and the left support rod 205 are fixedly connected to both sides of the fixing seat 204, and the lower ends of the right support rod 201 and the left support rod 205 are fixed to both sides of the fixing block 202. The fixing seat 204 fixes the right support rod 201 and the left support rod 205 to the top of the web reinforcement 104, and the fixing seat 204 is fixedly connected to the upper chord reinforcement 101; the fixing block 202 and the fixing seat 204 are rectangular blocks with round holes, and the upper chord reinforcement 101 passes through the round holes on the rectangular blocks. Multiple fixing seats 204 are fixed on each upper chord reinforcement 101, and the right support rod 201 and the left support rod 205 are fixed to the upper chord reinforcement 101 through the fixing seats 204. The right support rod 201 and the left support rod 205 are located between the two web reinforcements 104, and the right support rod 201 and the left support rod 205 are fixed at an angle. When the thin-walled plate is subjected to external force... The support rod and the left support rod 205 transmit part of the force to the fixed block 202. The fixed block 202 is fixedly connected to the longitudinal reinforcement 102, and multiple fixed blocks 202 are fixed on the longitudinal reinforcement 102. The external force on the thin-walled plate is transmitted to the longitudinal reinforcement 102 through the fixed block 202, so that the external force on the thin-walled plate is dispersed. The right support rod 201 and the left support rod 205 are cylindrical rods. The lower half of the right support rod 201 and the left support rod 205 are cast in the thin-walled plate, and the upper half is cast in the floor slab at the construction site. The right support rod 201 and the left support rod 205 can improve the overall strength of the floor slab and enhance the load-bearing capacity of the floor slab.

[0041] Preferably, the fixing block 202 is sleeved and welded to the longitudinal rib 102 before the longitudinal rib 102 and the transverse rib 103 are fixed. The spacing between each fixing block 202 is the same. There are 6 to 8 fixing blocks 202 fixed on each longitudinal rib 102. The number of fixing seats 204 and fixing blocks 202 is the same.

[0043] Preferably, the bottom of the web reinforcement 104 is parallel to the plane formed by the longitudinal reinforcement 102 and the transverse reinforcement 103; the diameter of the web reinforcement 104 is larger than the diameter of the longitudinal reinforcement 102 and the transverse reinforcement 103. The web reinforcement 104 mainly plays the role of resisting shear failure in the cast-in-place floor slab. The larger diameter web reinforcement 104 can improve the floor slab's ability to withstand shear failure and can control the width of the diagonal cracks in the floor slab, preventing the cracks from being too wide and affecting the integrity of the floor slab. The longitudinal reinforcement 102 and the transverse reinforcement 103 located at the bottom of the web reinforcement 104 can control the generation of floor slab cracks, thereby enabling the floor slab to withstand greater loads.

[0046] Preferably, the web reinforcement 104 used to fix the upper chord reinforcement 101 and the lower chord reinforcement 105 can be selected as a group of two, with one upper chord reinforcement 101 and one lower chord reinforcement 105 fixed on each group of web reinforcement 104.

[0048] Preferably, the bottom bend and the top bend of the web reinforcement 104 are perpendicular to each other. The top bend of the web reinforcement 104 is the steel bar that makes up the web reinforcement 104 bent upward at 130°. The bottom bend of the web reinforcement 104 is the steel bar that makes up the web reinforcement 104 bent towards one side of the web reinforcement 104 at 130°.

The length of the bottom bend of the crotch rib 104 varies with the spacing between the crotch ribs 104, so that the foremost point of the bottom bend of the crotch rib 104 can contact the foremost point of the bend of the adjacent crotch rib 104, and the adjacent crotch ribs 104 are welded and fixed together during welding. The connection between the longitudinal rib 102 and the transverse rib 103 is located below the connection between the adjacent crotch ribs 104, and the longitudinal rib 102 and the transverse rib 103 are welded and fixed to the bottom of the crotch rib 104.

[0050] Preferably, the longitudinal reinforcement 102 and the transverse reinforcement 103 are welded together at the connection point. The longitudinal reinforcement 102 and the transverse reinforcement 103 are welded and fixed at the welding and fixing points of two adjacent web reinforcements 104, so that the reinforcements are fixedly connected to form a whole, and the longitudinal reinforcement 102 and the transverse reinforcement 103 are perpendicular to each other.

[0051] Preferably, the fixing block 202 is a rectangular block with a semi-circular groove at the bottom. The bottom of the fixing block 202 is fixedly connected to the base plate 207 by a connecting bolt 208. The longitudinal rib 102 passes through the fixing block 202 and the base plate 207.
