Description

Technical Field

[0001] The utility model relates to a truss support frame tooling, which is applicable to the technical field of building structure construction. Background Art

[0002] Truss structures are widely used in the layout of building structural systems because of their reliable force bearing and beautiful appearance. In recent years, with the rapid development of steel structures, especially large-span steel structures, the application of steel truss systems has been widely welcomed by people in the industry. The sheet truss is the basic component unit of the large-span three-dimensional truss structure. At present, the construction method of the sheet truss is mainly frame assembly. The frame tooling commonly used in construction is often an on-site welded structure with cumbersome processing steps. After construction, it cannot be reused for the installation of trusses of other heights and needs to be cut and dismantled, resulting in a huge waste of resources. Therefore, the truss support frame tooling that can be assembled, recycled, and can meet different heights and different cross-sectional sizes has significant advantages and can greatly improve the technical and cost problems in the construction and installation of trusses. Utility Model Content

Thus, after the first bolt is screwed out of the first positioning hole, the telescopic rod moves in the telescopic sleeve, which is convenient for adjusting the telescopic length of the telescopic frame, and after the telescopic frame is adjusted to the corresponding position, the telescopic frame is locked at the corresponding length position by tightening the first bolt.

[0006] The fixing fixture has at least one pair of fixing plates installed on the base, the pair of fixing plates are respectively arranged on both sides of the lower chord, and the fixing plates are installed on the base through second bolts. In this way, when the lower chord of the truss is arranged on the base, the fixing plates are located at both sides of the lower chord of the truss, and the fixing plates on both sides play a role in limiting the truss.

[0007] A slot is formed on the base, and a second bolt installed on the fixing plate can move in the slot. Thus, when the support frame fixture is applied to trusses of various sizes, the second bolt is loosened and moved to a corresponding position in the slot, and the second bolt is tightened at the corresponding position, thereby adjusting the spacing between a pair of fixing plates, so that trusses of different sizes can be clamped.

[0008] A reinforcing rib is connected between the base and the telescopic frame, a first ear plate is installed at a position corresponding to the reinforcing rib on the base, a second ear plate is installed at a position corresponding to the reinforcing rib on the telescopic frame, and both ends of the reinforcing rib are connected to the first ear plate or the second ear plate through a pin shaft. In this way, the telescopic frame plays a stable supporting role.

[0009] The base is welded from a plurality of I-beams, and the ends of the I-beams are welded together, so that the base has good structural strength and stability.

[0010] The beneficial effects of the utility model are as follows: the utility model realizes the effect of height adjustment and quick assembly and fixing by splitting the telescopic frame into two parts, and connecting through the first positioning hole, the second positioning hole and the bolt; the fixing plate of the fixing fixture is slidably connected with the slot hole, and is adapted to different sizes of lower chord rods for fixing; the reinforcing ribs are connected between the base and the telescopic frame by a pin connection method, which is convenient for disassembly and reuse.
