[0023] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the present invention's technical solution and are therefore only examples and are not intended to limit the scope of protection of the present invention. Figures 1-4 As shown in .

[0024] A multi-support steel structure column assembly includes two spaced and vertically arranged column assemblies, the bottom of each column assembly is pre-buried and fixed on the ground 1, the tops of the two column assemblies are fixedly installed on the bottom of the steel structure beam 2, and a diagonal bracing unit is provided between the two column assemblies. The top of the diagonal bracing unit is movably hinged on an upper ear seat 3 fixedly connected to the upper part of the column assembly on the left, and the bottom of the diagonal bracing unit is movably hinged on a lower ear seat 4 fixedly connected to the lower part of the column assembly on the right. Side bracing accessories are respectively provided on the front and rear sides of the column assembly, the middle part of the side bracing accessories is connected to the diagonal bracing unit, and the two ends of the side bracing accessories are respectively installed at corresponding positions of the column assembly.

[0025] It should be noted that the multi-support steel structure column assembly as a whole can support the bottom end of the horizontally arranged steel structure beam 2. When supporting, relying on two spaced column assemblies can effectively ensure that the number of fulcrums is increased, and the stability of the support is effectively improved. In addition, considering the relative linkage between the two opposite column assemblies when relying on the two column assemblies on both sides for support, a diagonal bracing unit is added here to achieve the purpose of assisting in bearing the longitudinal load and connecting the two column assemblies, so that the entire column assembly structure forms a triangular frame stable structure under the action of the diagonal bracing unit, effectively ensuring the firmness of the entire support structure and improving the supporting capacity of the entire structure.

[0026] In any of the above schemes, it is preferred that the column assembly includes a box-type column 5, the lower end of the box-type column 5 is pre-buried and extends below the ground 1, a ground connection seat 6 is welded and fixed on the lower outer wall of the box-type column 5, the ground connection seat 6 is bolted to the ground 1, and the top of the box-type column 5 is fixed to the bottom of the steel structure beam 2.

[0027] The column assembly uses the box-type column 5 as the supporting body to effectively ensure the strength of the overall vertical support. At the same time, the stability of the bottom of the entire box-type column 5 is enhanced by pre-buried underground, ensuring its vertical support strength and anti-roll capability.

[0028] In any of the above schemes, it is preferred that the diagonal bracing unit includes an obliquely arranged flexure restraint support 7, the top of the left end of the flexure restraint support 7 is movably hinged on the upper ear seat 3, and the bottom of the right end of the flexure restraint support 7 is movably hinged on the lower ear seat 4, and a coaxially arranged threaded short shaft 8 is fixedly formed on the front and back sides of the middle part of the flexure restraint support 7, and an external thread is provided on the outer side wall of the threaded short shaft 8. The end of each threaded short shaft 8 passes through the middle part of the side support accessory at its corresponding position, and the external thread sections of the threaded short shaft 8 on both sides of the side support accessory are respectively screwed and fastened with locking nuts 9.

[0029] Taking into account the combined load-bearing effect of the two box-type columns 5, the upper and lower ends of the diagonal bracing unit are respectively connected to the corresponding two box-type columns 5 in an inclined manner, so that the two box-type columns 5 connected to the ground form a triangular frame support structure, which enhances the strength of the entire combined frame structure to a certain extent and ensures its stability when supporting the top steel structure beam 2; considering that the diagonal bracing unit is a lateral buckling restraint structural member, side bracing accessories are optimized and added on both sides thereof, so that horizontal extension can be completed on both sides of the middle part of the buckling restraint support 7, and finally the elastic support members at the bottom of both ends of the structure realize auxiliary elastic support when the middle part vibrates and displaces.

[0030] In any of the above schemes, it is preferred that the side support accessory includes a rigid sleeve 10 movably sleeved on the outer wall of the threaded short shaft 8, and coaxially arranged long screws 11 are integrally formed on the left and right sides of the rigid sleeve 10, and an external thread is provided on the outer wall of each of the long screws 11. The end of each of the long screws 11 extends to the outside of the box-type column 5 at its corresponding position and is connected with the elastic support member below the corresponding position.

[0031] It should be noted that the side support attachment is a connecting piece connected to both sides of the middle part of the flexure restraint support 7. Its main function is to support and position its two ends by relying on the supporting function of the elastic support member, so as to ensure that when encountering working conditions such as vibration loads, the vertical movement of the flexure restraint support 7 can rely on the long screws 11 on both sides to press down and transmit the pressure load to the elastic support member, thereby playing the role of elastic buffer support, and achieving the buffering purpose through elastic deformation and linkage.

[0032] In any of the above schemes, it is preferred that the elastic support member includes a supporting seat 12 fixedly welded on the lower outer wall of the box-type column 5, a supporting spring 13 is fixedly installed on the top of the supporting seat 12, and a square seat 14 is fixedly installed on the top of the support spring 13. The square seat 14 is movably sleeved on the outer wall of the long screw 11 through its center through hole, and end anti-slip nuts 16 are respectively screwed on the outer walls of the long screw 11 on both sides of the square seat 14, and the two end anti-slip nuts 16 cooperate to achieve clamping and positioning of the square seat 14 between them.

[0033] The elastic support member serves as a structure for bottom support of the end portion of the long screw rod 11 . When the end portion of the long screw rod 11 moves downward, it can provide elastic buffer support and reduce direct hard collision.

[0034] In addition, considering the stability after installation, multiple end anti-falling nuts 16 are provided to prevent falling and lock the connection, thereby ensuring the stability of the connection part. The use of locking nuts 9 can reduce the risk of falling off.

[0035] In any of the above solutions, preferably, a reinforcing plate seat 15 is fixedly welded to the bottom of each supporting seat 12 , and the reinforcing plate seat 15 is fixed to the lower outer side wall of the box-shaped column 5 .

[0036] Welding the reinforcing plate seat 15 at the bottom of the supporting seat 12 can better ensure the strength of the entire supporting seat 12 structure and ensure the stability of the supporting spring 13 on the top of the supporting seat.

[0037] In any of the above solutions, it is preferred that the inclination angle between the buckling restraining support 7 and the horizontal plane is 45°-60°.

[0038] Setting the buckling restraint support 7 to a suitable inclination angle can ensure the stability of the two triangular frame structures formed by it, the top steel structure beam 2, the ground 1 and the column components on both sides, and ensure the reasonable diversion of the longitudinal downward pressure load force.

[0039] Specific working principle: The multi-support steel structure column assembly of the utility model can support the bottom of the end of the horizontally arranged steel structure beam 2 as a whole. When supporting, relying on two spaced column components can effectively ensure the increase in the number of support points and effectively improve the stability of the support.

[0040] The diagonal bracing unit added between the two column assemblies can play the role of buckling restraint support 7, and at the same time, after cooperating with the column assemblies on both sides, it can form two triangular frame structures, effectively ensuring the stability of the entire support structure; the diagonal bracing unit is added to achieve the purpose of assisting in bearing the longitudinal load and connecting the two column assemblies, effectively ensuring the firmness of the entire support structure and improving the supporting capacity of the entire structure.

[0041] From the above, it can be seen that the multi-support steel structure column assembly can stably support the bottom of the steel structure beam 2 by relying on two relatively spaced and vertically arranged column assemblies, and can achieve double-point support within a certain span, effectively improving the stability of the support; while providing double-point support, relying on the inclined flexure constraint support 7 can further improve the lateral support anti-seismic effect, and assist in enhancing the overall support strength; the side support accessories and corresponding elastic support members arranged on the front and rear sides of the diagonal bracing unit can effectively ensure stable support for the middle part of the diagonal bracing unit, and effectively ensure the fulcrum positioning support; the elastic support members arranged on the front and rear sides of each box-type column 5 can effectively ensure that the side support accessories play a good elastic support role when subjected to small up and down movements.
