Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fabricated truss structure, and particularly relates to a steel structure anti-seismic truss. BACKGROUND

[0002] The truss is a plane or space structure composed of straight rods with triangular units, and the rod of the truss mainly bears axial tension or pressure, so that the strength of the material can be fully utilized. When applied to a structure with a large span, the truss can save material, reduce self-weight and increase rigidity compared with a solid-web beam. The existing truss is generally connected by a plurality of support rods to two cross rods, and the plurality of support rods and the cross rods are distributed in a triangular shape, so as to improve the stability and the anti-seismic property of the truss through the triangular structure.

[0003] The existing truss is generally connected by welding or bolts between the cross rod and the support rod. Such a structure causes the width size of the truss after assembly to be fixed. For the truss installed at a fixed position for a long time, such a structure is more suitable. However, for the support truss of a temporary structure, because the application scenarios involved are various, the assembly environment to which the truss needs to be adapted is also various. For such a case, if the truss with a fixed width is used, it is inevitable that a plurality of trusses with different width sizes need to be separately arranged, which not only causes the production cost to increase, but also may cause the low utilization rate of part of the trusses, resulting in the waste of resources. SUMMARY

[0004] The purpose of the embodiment of the application is to provide a steel structure anti-seismic truss, which aims to solve the problems in the background technology.

[0005] The embodiment of the application is implemented as follows: a steel structure anti-seismic truss, comprising a truss main body, the truss main body comprising a connecting beam, two side beams symmetrically arranged on both sides of the connecting beam; further comprising:

[0006] a connecting assembly, a plurality of groups of connecting assemblies are symmetrically arranged on both sides of the connecting beam, and the connecting beam is connected with the side beam through the connecting assembly, the connecting assembly comprising two symmetrically arranged connecting struts, one end of the connecting strut close to the side beam being provided with a first connecting shaft, and the side beam being provided with a first guide sliding groove matched with the first connecting shaft, a mounting hole matched with the connecting strut being formed in the side wall of the connecting beam, and the connecting strut close to the connecting beam being rotatably mounted in the mounting hole through a mounting pivot, one end of the connecting strut close to the connecting beam penetrating the side wall of the connecting beam, and the connecting beam further being provided with an adjusting assembly for adjusting the distance between the side beam and the connecting beam by driving the two connecting struts in the same group of connecting assemblies to reversely rotate;

[0008] Further, the mounting shaft is sleeved with a first damping spring at both ends, and the two ends of the first damping spring are connected with the mounting hole and the connecting strut respectively.

[0009] Further, the auxiliary adjusting assembly comprises two second adjusting plates symmetrically arranged between the two first adjusting plates, and the second damping spring is mounted between the two second adjusting plates, a second threaded rod is rotatably mounted in the first threaded rod, the second threaded rod is coaxially mounted with the first threaded rod, one end of the second threaded rod is located outside the first threaded rod, the other end of the second threaded rod penetrates the first adjusting plate and is connected with the second adjusting plate, and the first adjusting plate is provided with a threaded hole matched with the second threaded rod.

[0010] Further, the second adjusting plate is further provided with a plurality of avoiding holes for preventing the second adjusting plate from interfering with the end of the connecting strut.

[0011] Further, the first threaded rod is provided with a first knurled handle at one end outside the connecting beam, which can be used to increase the roughness of the first threaded rod, so as to facilitate the operator to rotate the first threaded rod.

[0012] Further, the second threaded rod is provided with a second knurled handle at one end outside the connecting beam, which is also used to increase the roughness of the second threaded rod.

Specifically, the first threaded rod is rotated, and the first threaded rod can push the first adjusting plate to move along the axial direction of the first threaded rod under the cooperation of the first threaded rod and the threaded hole on the connecting beam. The linear movement of the first adjusting plate can be converted into the rotation of the connecting strut under the cooperation of the second connecting shaft and the second guide sliding groove (in this process, the second connecting shaft will slide in the second guide sliding groove).

[0026] The adjusting assembly 3 comprises two first adjusting plates 32 symmetrically mounted in the connecting beam 11, a plurality of second damping springs 35 are arranged between the two first adjusting plates 32, and an auxiliary adjusting assembly 4 for adjusting the damping of the second damping springs 35 is further arranged on the first adjusting plate 32, a first threaded rod 31 for adjusting the spacing between the two first adjusting plates 32 is further mounted on the connecting beam 11, one end of the first threaded rod 31 is rotatably mounted on the first adjusting plate 32, the end of the first threaded rod 31 away from the first adjusting plate 32 penetrates through the side wall of the connecting beam 11, and a threaded hole matched with the first adjusting plate 32 is arranged on the connecting beam 11, and one end of the connecting strut 21 inside the connecting beam 11 is provided with a second connecting shaft 33, and the first adjusting plate 32 is provided with a second guide sliding groove 34 matched with the second connecting shaft 33.

[0027] In the embodiment of the present application, during use, the width of the device as a whole (i.e. the spacing between the two side beams 12) can be adjusted according to actual use requirements, which can be achieved by adjusting the spacing between the side beam 12 and the connecting beam 11. Specifically, only by rotating the first threaded rod 31, under the cooperation of the first threaded rod 31 and the threaded hole on the connecting beam 11, the first threaded rod 31 can push the first adjusting plate 32 to move along the axial direction of the first threaded rod 31, under the cooperation of the second connecting shaft 33 and the second guide sliding groove 34, the linear movement of the first adjusting plate 32 can be converted into the rotation of the connecting strut 21 (in this process, the second connecting shaft 33 will slide in the second guide sliding groove 34), in the process of rotating the connecting strut 21, the first connecting shaft 22 will slide in the first guide sliding groove 23 synchronously, and the spacing between the side beam 12 and the connecting beam 11 can be adjusted by controlling the rotation amplitude of the connecting strut 21.

The second threaded rod 41 is coaxially installed with the first threaded rod 31. One end of the second threaded rod 41 is located outside the first threaded rod 31. The other end of the second threaded rod 41 passes through the first adjustment plate 32 and is connected to the second adjustment plate 42.

At the same time, the second shock absorbing spring 35 between the two first adjusting plates 32 can be used to offset the influence of lateral vibration on the device. In addition, in the adjustment process, the distance between the two first adjusting plates 32 will also change accordingly, the two first adjusting plates 32 can stretch or compress the second shock absorbing spring 35, so as to provide a pre-tightening force for the second shock absorbing spring 35, so as to change the lateral shock absorbing effect of the device.
