A high-safety torsion-resistant steel structure truss

Abstract

The present invention provides a high-safety torsion-resistant steel structure truss, which belongs to the technical field of steel structure. It includes a first connecting beam and a second connecting beam. An anti-torsion mechanism is arranged between the first connecting beam and the second connecting beam. The anti-torsion mechanism includes a torsion seat. A plurality of buffer plate groups and a plurality of anti-torsion adjustment mechanisms are movably mounted on the torsion seat. By designing the anti-torsion mechanism at the connection between the first connecting beam and the second connecting beam, the steel structure truss has high-safety torsion-resistant performance. When the first connecting beam or the second connecting beam is subjected to external force from any direction and the torque is transmitted to the anti-torsion mechanism, the torque will be eliminated by the mutual cooperation of the buffer plate groups and the anti-torsion adjustment mechanisms on the torsion seat in a small-angle swing buffering manner. The force at the fixed connection between the two will be weakened and reduced, thereby solving the problem of insufficient torsion resistance caused by existing screw fixed connection or welding, and improving the overall safety of the steel structure truss.

Description

Technical Field

[0001] The invention relates to a high-safety torsion-resistant steel structure truss, belonging to the technical field of steel structures. Background Art

[0002] Steel structures are structures made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, made from sections and plates. Rust removal and prevention processes include silanization, pure manganese phosphating, water washing and drying, and galvanizing. Components are typically connected using welds, bolts, or rivets. Due to its light weight and ease of construction, it is widely used in large factories, stadiums, and high-rise buildings.

[0003] When existing steel structure trusses are installed, their joints are usually fixed by welding or multiple screw connections, which makes the installation work not only cumbersome and labor-intensive, but also in the process of use after installation, after being subjected to external forces, the welded or screwed connection parts will be subjected to large torsional forces, resulting in screw loosening or cracking of the welds. The torsional performance of the steel structure truss is insufficient. In response to the above problems, the present invention proposes a high-safety torsion-resistant steel structure truss to solve the above problems. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a high-safety torsion-resistant steel structure truss to solve the existing problems.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a high-safety torsion-resistant steel structure truss, including a first connecting beam and a second connecting beam, an anti-torsion mechanism is arranged between the first connecting beam and the second connecting beam, the anti-torsion mechanism includes a torsion seat, and a plurality of buffer plate groups and a plurality of anti-torsion adjustment mechanisms are movably mounted on the torsion seat, the number of each buffer plate group is four, and the number of each anti-torsion adjustment mechanism is four.

[0006] A further improvement is that a plurality of retaining grooves are provided on one side of the second connecting beam, and an inner arc edge is provided on the side of each retaining groove.

[0007] A further improvement is that the torsion seat includes a torsion seat body, a beam sleeve opened in the middle of one side of the torsion seat body, a plurality of torque adjustment mechanism slides opened on the beam sleeve, and a plurality of buffer plate group slides, and each of the buffer plate group slides has a plurality of plate pin through-holes opened on its side.

[0008] A further improvement is that each of the buffer plate groups includes a pressure cover and a buffer plate, a plurality of buffer springs are provided between the pressure cover and the buffer plate, and a plurality of bayonet pins are provided on the movable sleeves on the sides of the buffer plate.

[0009] As a further improvement, a plurality of first buffer spring positioning openings are provided at intervals on the inner side surface of the pressure cover, a plurality of second buffer spring positioning openings are provided at intervals on the outer side surface of the buffer plate, and a plurality of latch sliding openings are provided on the side of the buffer plate.

[0010] A further improvement is that each of the anti-torsion adjustment mechanisms includes an adjustment seat, a threaded rod threadedly connected to the adjustment seat, a rotating seat arranged at the lower end of the threaded rod, an anti-torsion spring group arranged on the bottom surface of the rotating seat, and a pressure block arranged on the bottom surface of the anti-torsion spring group, the lower end side of the pressure block is provided with an outer arc edge, and the upper end of the threaded rod is provided with a handle.

[0011] A further improvement is that the torsion spring group includes a torsion spring, a first spring seat and a second spring seat arranged on both sides of the torsion spring.

[0012] A further improvement is that the inner diameter of the sliding opening of the torque adjustment mechanism is 2-3 mm larger than the outer diameter of the pressing block.

[0013] A further improvement is that the inner diameter length and width of the sliding opening of the buffer plate group are both 3-4MM larger than the outer diameter length and width of the buffer plate.

[0014] A further improvement is that the inner arc edge is adapted to the outer arc edge.

[0015] The beneficial effects of the invention are:

[0016] The present invention provides a high-safety torsion-resistant steel structure truss. Through the design of the torsion-resistant mechanism at the connection between the first connecting beam and the second connecting beam, the steel structure truss has high-safety torsion-resistant performance. When the first connecting beam or the second connecting beam is subjected to external force from any direction to generate torsion that is transmitted to the torsion-resistant mechanism, the buffer plate groups and the anti-torsion adjustment mechanisms on the torsion seat will cooperate with each other to eliminate the torsion by a small-angle swing buffering method. The force at the fixed connection between the two will be weakened and reduced, thereby solving the problem of insufficient torsion-resistant performance caused by existing screw fixed connection or welding, and improving the overall safety of the steel structure truss.

[0017] The design of the anti-torsion adjustment mechanism can adjust the torsional strength according to the length of the connecting beam, and can adapt to the installation of connecting beams of different lengths. The inner diameter of the sliding mouth of the torque adjustment mechanism is designed to be 2-3MM larger than the outer diameter of the pressure block, so that when torque is generated, the pressure block has the function of shaking at a small angle without specifications and close to the connecting beam, thereby increasing the force-bearing area and increasing safety and stability.

[0018] The design of the buffer plate group, supplemented by the anti-torque adjustment mechanism on the front side of the torsion seat to buffer the torque, further increases the force-bearing surface for buffering and eliminating torque, and further improves safety. The design of the inner diameter, length and width of the sliding mouth of the buffer plate group is 3-4MM larger than the outer diameter, length and width of the buffer plate, so that each buffer plate will also cling to each surface of the connecting beam and perform small-angle elastic swing to eliminate torque, thereby increasing safety and stability.

A plurality of positioning grooves 21 are provided on one side of the second connecting beam 2, and an inner arc edge 22 is provided on the side of each positioning groove 21. The torsion seat 4 includes a torsion seat body 41, a beam sleeve 42 opened in the middle of one side of the torsion seat body 41, a plurality of torsion adjustment mechanism slides 43 and a plurality of buffer plate group slides 44, and a plurality of flat plate pin through-holes 45 are opened on the side of each buffer plate group slide 44. The plate 52 has a plurality of buffer springs 53 arranged between the pressure cover 51 and the buffer plate 52, and a plurality of latches 54 are movably sleeved on the side of the buffer plate 52. A plurality of first buffer spring positioning openings 511 are spaced apart on the inner side surface of the pressure cover 51, and a plurality of second buffer spring positioning openings 521 are spaced apart on the outer side surface of the buffer plate 52. A plurality of latch sliding openings 522 are opened on the side of the buffer plate 52. Each of the anti-torque adjustment mechanisms 6 includes an adjustment seat 61, a threaded rod 62 threadedly connected to the adjustment seat 61, a rotating seat 63 arranged at the lower end of the threaded rod 62, a torsion spring group 64 arranged on the bottom surface of the rotating seat 63, and a pressure block 65 arranged on the bottom surface of the torsion spring group 64. The lower end side of the pressure block 65 is provided with an outer arc edge 66, and the upper end of the threaded rod 62 is provided with a handle 67. The torsion spring group 64 includes a torsion spring 641, a first spring seat 642 and a second spring seat 643 arranged on both sides of the torsion spring 641.

[0028] Working principle:

[0029] Installation method: First, raise the pressure blocks 65 on each anti-torque adjustment mechanism 6 at the rear side of the beam sleeve 42 cavity, and the buffer plate group 5 first only installs the buffer plate 52 in the buffer plate group slide 44 and fixes it movably with each pin 54, and then insert one end of the second connecting beam 2 into the beam sleeve 42 cavity. At this time, each positioning groove 21 and each pressure block 65 are aligned, and then the threaded rod 62 is twisted in turn to make each pressure block 65 press one end of the second connecting beam 2 from each direction. In this process, the inner arc edge 22 and the outer arc edge 66 will cooperate with each other for fine-tuning so that each pressure block 65 is completely correspondingly inserted into each positioning groove 21 for fixation, and then the pressure cover 51 on each buffer plate group 5 and the matching buffer springs 53 are successively put on the outside of the buffer plate 52 and fixed with screws to complete the installation.

[0030] The method of use is to adjust the tensioning strength of the torsion spring 641 on each anti-torsion adjustment mechanism 6 according to the extension length of the other end of the second connecting beam 2. When the length of the second connecting beam 2 is longer, the tensioning strength of the torsion spring 641 should be adjusted to be stronger, and when the length of the second connecting beam 2 is shorter, the tensioning strength of the torsion spring 641 should be adjusted to be weaker. Because the longer the length, the greater the torque generated by the same external force, and the adaptive adjustment of the torsion strength is completed. For example, when the top of the second connecting beam 2 is subjected to the downward pressure external force and transmitted to the anti-torsion mechanism 3, the torsion spring 641 on the anti-torsion adjustment mechanism 6 at the top of the torsion seat 4 will shrink and tighten to eliminate the torque, and the torsion spring 641 at the bottom will release the corresponding elastic force, and the upper and lower buffer plates 52 on each buffer plate group 5 will make a small angle of buffering swing relative to each other to eliminate the torque, and finally perform initial recovery under the action of the torsion spring 641 and each buffer spring 53.
