Description

Technical Field

[0001] This utility model relates to the field of steel structure support truss technology, specifically to a steel structure support truss with anti-torsion function. Background Technology

[0002] In truss structures, trusses refer to truss beams, a type of lattice-structured beam. Truss structures are commonly used in public buildings such as large-span factories, exhibition halls, stadiums, and bridges. Because they are mostly used in roof structures, trusses are often also called roof trusses.

[0003] Existing support trusses have certain drawbacks in use. First, during installation, the support trusses need to be raised and lowered, which generates torque and bending force, thereby compromising the stability and integrity of the support trusses, causing some wear and tear on the internal structure, and thus reducing the service life of the support trusses.

[0004] Therefore, it is necessary to propose a steel structure support truss with anti-torsion function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure support truss with anti-torsion function. Through the cooperation of the internal parts of the anti-torsion structure, the truss body and the support column can be connected at a 90-degree angle. By using triangular reinforcing ribs and connecting columns to penetrate into the interior of the truss body, the anti-torsion performance of the truss body can be improved. Furthermore, by wrapping the outer wall of the truss body with a corrosion-resistant internal structure, the corrosion resistance of the truss body can be improved, thereby increasing the service life of the truss body. This solves the problem in the prior art where the support truss needs to be raised and lowered during installation, which causes the support truss to generate some torque and bending force, thereby compromising the stability and integrity of the support truss, causing certain wear and tear on the internal structure of the support truss, and thus reducing the service life of the support truss.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure support truss with anti-torsion function, comprising a truss body, a support column bolted to the top of the truss body, an anti-torsion structure bolted to the connection between the support column and both sides of the truss body, and penetrating the support column to the interior of the truss body, the outer wall of the truss body is provided with a corrosion-resistant structure and sleeved with the outer wall of the truss body;

[0007] The anti-torsion structure includes multiple connecting plates, which are welded and fixed to both ends of the supporting column and attached to both ends of the outer wall of the truss body by bolts. Triangular reinforcing ribs are welded and fixed to both sides of the outer wall of the supporting column and attached to the top of the truss body. A connecting column is welded and fixed to the bottom end of the triangular reinforcing rib and extends into the interior of the truss body.

[0008] Preferably, the anti-torsion structure further includes a limiting column, which is slidably connected to the interior of the truss body and extends through the truss body to the interior of the connecting column. The top surface of the truss body is integrally formed with multiple supporting columns, which extend through the interior of the supporting columns.

[0009] Preferably, the corrosion-resistant structure includes a first anti-torsion layer on the top surface of the truss body and in contact with the bottom end of the supporting column, a second anti-torsion layer is provided at the bottom end of the truss body, and a steel structure body is provided between the first anti-torsion layer and the second anti-torsion layer.

[0010] Preferably, the truss body and the supporting column are provided with multiple bolt holes on their surfaces, the top of the triangular reinforcing rib is provided with a bolt hole and extends to the top of the truss body, the top of the truss body is provided with a docking hole that matches the docking column, and a buffer layer is provided around the surface of the supporting column.

[0011] Preferably, a sliding groove matching the limiting column is provided between the docking hole and the bolt hole inside the truss body, the contact surface between the limiting column and the docking column is provided with an arc surface, and a connecting groove matching the supporting column is provided at the bottom end of the supporting column.

[0012] Preferably, the cross-section of the steel structure body is a honeycomb structure, and the main material of the steel structure body is weathering steel. The first anti-torsion layer is mainly made of galvanized material, and the bottom surface of the second anti-torsion layer is provided with an oxide layer, and the main material is aerospace high-temperature alloy.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By perpendicularly fitting the support column to the truss body, the support column drives the connecting plates at both ends of the outer wall to fit with the two ends of the outer wall of the truss body. Bolts are then inserted through the connecting plates into the truss body to complete the connection and fixation between the support column and the truss body. The mutual fitting of the support column and the truss body allows the support column at the top of the truss body to penetrate into the support column. At the same time, the support column drives the triangular reinforcing ribs on both sides to fit with the top of the truss body and drives the connecting column to penetrate into the truss body. Bolts are then inserted through the triangular reinforcing ribs into the truss body to complete the connection and fixation between the triangular reinforcing ribs and the truss body. Simultaneously, the bolts compress the limiting column, causing it to slide into the connecting column, thus limiting and fixing the connecting column within the truss body. This facilitates the stability of the truss body and support column when they are subjected to bending forces, as the triangular reinforcing ribs can bear the force. Furthermore, the truss body and support column distribute and transmit torque through the support column and connecting column, thereby improving the torsional resistance of the truss body and support column.

[0015] 2. The cross-section of the steel structure body is a honeycomb structure, which allows the honeycomb structure to withstand more external forces when the truss body is subjected to bending stress, thus providing good stability. The main material of the steel structure body is weather-resistant steel, which helps to improve the high strength of the truss body itself. The first anti-torsion layer is mainly made of galvanized material, and the bottom surface of the second anti-torsion layer is provided with an oxide layer, and the main material is aerospace high-temperature alloy, which helps to improve the corrosion and oxidation resistance of the truss body itself, thereby increasing the service life of the truss body.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The steel structure support truss with anti-torsion function shown includes a truss body 1, a support column 101 is bolted to the top of the truss body 1, an anti-torsion structure 2 is bolted to the connection between the support column 101 and the two sides of the truss body 1, and penetrates the support column 101 to the interior of the truss body 1, and a corrosion-resistant structure 3 is provided on the outer wall of the truss body 1 and sleeved with the outer wall of the truss body 1.

[0025] The anti-torsion structure 2 includes a connecting plate 201. There are multiple connecting plates 201. The multiple connecting plates 201 are welded and fixed to both ends of the support column 101 and are attached to both ends of the outer wall of the truss body 1 by bolts. Triangular reinforcing ribs 202 are welded and connected to both sides of the outer wall of the support column 101 and are attached and fixed to the top of the truss body 1. The bottom end of the triangular reinforcing rib 202 is welded and fixed to the butt column 203, which penetrates into the interior of the truss body 1.

[0026] The internal components of the anti-torsion structure 2 work together to facilitate a 90-degree vertical connection between the truss body 1 and the supporting column 101. The triangular reinforcing ribs 202 and the connecting column 203 penetrate into the interior of the truss body 1, thereby improving the torsional resistance of the truss body 1. Furthermore, the corrosion-resistant structure 3 wraps around the outer wall of the truss body 1, thereby improving its corrosion resistance and extending its service life.

[0027] Refer to the instruction manual appendix Figure 1-4 The anti-torsion structure 2 also includes a limiting column 204, which is slidably connected to the interior of the truss body 1 and extends through the truss body 1 to the interior of the connecting column 203. The top surface of the truss body 1 is integrally formed with multiple supporting columns 205, which extend through the interior of the supporting column 101. Through the mutual cooperation of the internal parts of the anti-torsion structure 2, the truss body 1 and the supporting column 101 are connected at a 90-degree angle. The anti-torsion performance of the truss body 1 can be improved by the triangular reinforcing rib 202 and the connecting column 203 extending through the interior of the truss body 1.

[0028] Refer to the instruction manual appendix Figure 1-4 The corrosion-resistant structure 3 includes a first anti-torsion layer 301, which is located on the top surface of the truss body 1 and is attached to the bottom end of the supporting column 101. A second anti-torsion layer 303 is provided at the bottom end of the truss body 1. A steel structure body 302 is provided between the first anti-torsion layer 301 and the second anti-torsion layer 303. By wrapping the internal structure of the corrosion-resistant structure 3 around the outer wall of the truss body 1, the corrosion resistance of the truss body 1 can be improved, thereby increasing the service life of the truss body 1.

[0029] Refer to the instruction manual appendix Figure 1-4Multiple bolt holes are provided on the surfaces of the truss body 1 and the support column 101. Bolt holes are provided at the top of the triangular reinforcing rib 202 and extend to the top of the truss body 1. The top of the truss body 1 is provided with a mating hole that matches the connecting column 203. A buffer layer is provided around the surface of the support column 205. The connecting hole that matches the connecting column 203 is provided at the top of the truss body 1 and the buffer layer is provided around the surface of the support column 205, so that the connecting column 203 can penetrate into the interior of the truss body 1. This allows the support column 101 to distribute and transfer part of the torque to the truss body 1 through the connecting column 203, and allows the support column 205 to relieve and buffer the force between the truss body 1 and the support column 101 through the buffer layer.

[0030] Refer to the instruction manual appendix Figure 1-4 The truss body 1 has a sliding groove between the docking hole and the bolt hole that matches the limiting column 204. The contact surface between the limiting column 204 and the docking column 203 is provided with an arc surface. The bottom end of the support column 101 has a connecting groove that matches the support column 205. The connecting groove at the bottom end of the support column 101 makes it easy for the support column 205 to pass through into the support column 101, so that the truss body 1 can transmit torque to the support column 101 through the support column 205.

[0031] Refer to the instruction manual appendix Figure 1-4 The steel structure body 302 has a honeycomb structure in cross-section, and the main material of the steel structure body 302 is weathering steel. The first anti-torsion layer 301 is mainly made of galvanized material, and the bottom surface of the second anti-torsion layer 303 is provided with an oxide layer, and the main material is aerospace high-temperature alloy. The honeycomb structure in cross-section of the steel structure body 302 and the weathering steel material of the steel structure body 302 facilitate the improvement of the high strength of the truss body 1 itself. The honeycomb structure in cross-section of the steel structure body 302 also facilitates the truss body 1 to withstand more external forces when it is subjected to bending stress, thus having good stability.

[0032] The working principle of this practical application is as follows:

[0033] Refer to the instruction manual appendix Figure 1-4By perpendicularly attaching the support column 101 to the truss body 1, the support column 101 drives the connecting plates 201 at both ends of the outer wall to attach to the two ends of the outer wall of the truss body 1. Bolts are then inserted through the connecting plates 201 into the interior of the truss body 1, completing the connection and fixation between the support column 101 and the truss body 1. The mutual attachment of the support column 101 and the truss body 1 allows the support column 205 at the top of the truss body 1 to penetrate into the support column 101. Simultaneously, the support column 101 drives the triangular reinforcing ribs 202 on both sides to attach to the top of the truss body 1, and drives the connecting column 203 to penetrate into the interior of the truss body 1. Bolts are then inserted through the triangular reinforcing ribs 202 into the interior of the truss body 1. By connecting the reinforcing rib 202 to the truss body 1, the connection and fixation between the triangular reinforcing rib 202 and the truss body 1 can be completed. At the same time, the bolt presses the limiting column 204 to move, so that the limiting column 204 slides into the connecting column 203, so that the connecting column 203 can be limited and fixed within the truss body 1. When the truss body 1 and the supporting column 101 are subjected to bending force, the triangular reinforcing rib 202 can bear the force to improve the stability of the truss body 1 and the supporting column 101. At the same time, the truss body 1 and the supporting column 101 distribute and transmit the torque through the supporting column 205 and the connecting column 203 respectively, thereby improving the torsional resistance of the truss body 1 and the supporting column 101.

[0034] Refer to the instruction manual appendix Figure 1-4 The cross-section of the steel structure body 302 is a honeycomb structure, which allows the truss body 1 to withstand more external forces when it is subjected to bending stress, thus providing good stability. The main material of the steel structure body 302 is weather-resistant steel, which helps to improve the high strength of the truss body 1. The first anti-torsion layer 301 is mainly made of galvanized material, and the bottom surface of the second anti-torsion layer 303 is provided with an oxide layer, and the main material is aerospace high-temperature alloy, which helps to improve the corrosion and oxidation resistance of the truss body 1, thereby increasing the service life of the truss body 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
