Buckle and building template supporting steel pipe joist manufactured by using same

Abstract

The invention discloses a buckle and a building template supporting steel pipe joist manufactured by using the buckle, and relates to the technical field of buildings, in particular to the technology of the building template supporting steel pipe joist, the buckle comprises three round steel pipes and the buckle capable of tightly hooping the three round steel pipes which are piled together, and the three steel pipes are tightly piled together in a triangle shape to form three steel pipe bundles. And a plurality of buckles are distributed along the three-steel-pipe bundle and are tightly hooped on the three-steel-pipe bundle. Compared with the prior art, the formwork has the advantages that small pieces can be adopted for transmission, operation is convenient during on-site assembly and disassembly, steel pipes are cooperated, and meanwhile the requirement for supporting force of the formwork can be met without increasing the distance between the vertical rods.

Description

technical field [0001] The invention relates to the field of building technology, in particular to the technology of building formwork supporting steel pipe joists. Background technique [0002] In the formwork support system, the formwork support joist (main corrugation) is an important force-transmitting member in the formwork support system. In the design of the formwork support, often because the bearing capacity of the support joist cannot be satisfied, it is generally necessary to encrypt the lower support vertical The vertical and horizontal spacing of the poles reduces the span of the supporting joists to ensure the safety of the supporting system. Therefore, there is a lot of surplus in the load-bearing capacity of the lower support pole, which fails to give full play to the load-bearing performance of the pole, wastes materials, and increases the construction cost. [0003] At present, the materials used for formwork support joists mainly include wooden beams, ste...

AI Technical Summary

Problems solved by technology

When wooden beams, steel pipes, and small section steel are used as supporting joists, the safety and deformation of the support system must be ensured by encrypting the distance between the vertical poles. It is difficult to cooperate with the force of double steel pipes; if large section steel is used as supporting joists , although the lower vertical poles can be adjusted to an appropriate distance, but the large-section steel is heavy and difficult to operate during material transfer, installation, and dismantling, and even requires a tower crane to cooperate with the construction. Because the large-section steel is relatively heavy (the length of a single piece is 3m, generally 25kg Above), in the process of dismantling the joists, the tower crane cannot be used to cooperate with the dismantling construction, and only manual operation can be used, which increases the construction safety risk, and the heavy steel is easy to directly hit the underlying structure and cause structural damage
