A detachable prestressed steel truss composite panel

Abstract

The invention discloses a detachable prestressed steel bar truss composite board, belonging to the technical field of composite board equipment. A detachable prestressed steel bar truss composite board comprises a template on which a plurality of evenly distributed detection cylinders are fixedly connected , it can use the characteristics of expansive soil to absorb water, expand and shrink after pouring concrete to determine whether the poured concrete is in a solidified state. The use of the reflector can serve as a reminder to inform the staff that the formwork can be removed at present, so as to prevent the staff from dismantling the formwork in advance because they cannot know whether the interior of the concrete is solidified, resulting in the loss of the formwork for the incompletely solidified concrete. Cracks will occur after the support of the splicing, in addition, through a plurality of spliced ​​formwork strips, the problem that the existing formwork is difficult to disassemble due to its large size can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of laminated board equipment, and more particularly, to a detachable prestressed steel bar truss laminated board. Background technique [0002] Laminated slab is a kind of building formwork that combines prefabricated and cast-in-place concrete. The connecting parts of the laminated board are welded by the keel steel truss. When the concrete is poured, the connecting parts of the laminated board are integrated with the steel bars and the concrete, which play a more bonding and firmer role. During the construction stage, the board body of the laminated board is As a formwork for pouring concrete, the strength and stiffness of the formwork are provided by steel trusses welded to the keel. In the construction phase, laminated slabs were used as formwork for pouring concrete, and the strength and rigidity of the formwork were supported by trusses welded together by steel bars. [0003] When concrete is poured ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a detachable prestressed steel truss laminated slab. The present invention can use the characteristics of expansive soil to absorb water and shrink when it loses water to determine the quality of the pouring after the concrete is poured. Whether the concrete is in a solidified state. When the concrete is solidified, the water loss and shrinkage of the expansive soil will cause the prompt rod to drop. Using the reflector can serve as a reminder to inform the staff that the formwork can be removed at present, so as to To prevent the staff from dismantling the formwork in advance because they cannot know whether the concrete is solidified inside, resulting in cracks in the incompletely solidified concrete due to the loss of the support of the formwork. In addition, the multi-spliced ​​strip formwork can effectively solve the problem Some templates are difficult to disassemble due to their large size
