Embodiment 1

[0046] refer to figure 1 , the support structure for the large-span truss includes a tire frame 1 and an adjustment device 2, the tire frame 1 is fixed on the backing plate 7, the adjustment device 2 is positioned and installed on the top of the tire frame 1, the adjustment device 2 has an adjustable height, and the adjustment device 2 Where it conflicts with the lower chord 9 of the truss, the tire frame 1 and the adjustment device 2 provide stable support for the lower chord 9 of the truss.

[0047] refer to figure 1The tire frame 1 includes a plurality of standard sections 11, and the tire frame 1 is formed by stacking the standard sections 11 up and down. The specification of the standard sections 11 is 1.8m*1.8m*2.8m, and the corners of the standard sections 11 are welded with threaded sleeves 111 , the bolt is inserted into the threaded sleeve 111 and threadedly matched with the threaded sleeve 111 to realize the fixation between the standard sections 11 . The inside o...

Embodiment 2

[0060] A construction method for a support structure of a long-span truss, comprising the following steps,

[0061] S1: Install the backing plate 7. By pouring concrete on the ground, the backing plate 7 is horizontally fixed on the concrete ground, and the supporting structure is placed on the backing plate 7 without causing damage to the backing plate 7.

[0062] S2: Fix the first standard section 11, clamp the threaded sleeve 111 on the standard section 11 through the clamping plate 5, and weld the clamping plate 5 on the backing plate 7, so that the first standard section 11 is stably fixed on the backing plate 7.

[0063] S3: stack the standard sections 11 up and down, and realize the fixing between the standard sections 11 by bolts, and finally form the tire frame 1 .

[0064] S4: Install the adjustment device 2 on the tire frame 1, and set the positioning plate 4 on the adjustment device 2 with the tire frame 1, and then the adjustment device 2 and the tire frame 1 mai...

Abstract

The invention relates to a large-span truss supporting structure and a construction method thereof, in particular to the field of constructional engineering. The supporting structure comprises a jig frame and an adjusting device installed on the jig frame, wherein the jig frame is placed on a base plate, the adjusting device comprises a base, an adjustable supporting column and a driving piece, the base is in location fit with the jig frame, and the adjustable supporting column and the driving piece are fixed to the side, without the jig frame, of the base. The structure solves the problem that a truss supporting structure is too troublesome in the construction process.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a support structure for a long-span truss and a construction method thereof. Background technique [0002] With the continuous development of steel structure construction technology, steel structure systems with complex structures and larger spans are increasingly appearing in the field of engineering construction, and the technical issues related to the construction of long-span steel trusses have gradually received attention. [0003] With regard to the related technologies mentioned above, the inventor believes that there is a defect that the construction process of the supporting structure of the truss is too troublesome. Contents of the invention [0004] In order to improve the problem that the truss support structure is too troublesome in the construction process, the application provides a support structure for a long-span truss and a construc...
