Detachable prestressed steel bar truss laminated slab

Abstract

The invention discloses a detachable prestressed steel bar truss laminated slab, and belongs to the technical field of laminated slab equipment, the detachable prestressed steel bar truss laminated slab comprises a template, the template is fixedly connected with a plurality of uniformly distributed detection cylinders, and after concrete is poured, the detection cylinders can be used for detecting whether the detection cylinders are uniformly distributed or not by utilizing the characteristics that expansive soil absorbs water to swell and shrinks due to water loss; whether the poured concrete is in a solidification state or not is judged according to the water loss shrinkage of the expansive soil, after the concrete is solidified, the falling of the prompt rod is caused by the water loss shrinkage of the expansive soil, and the reflective mirror can play a role in reminding to inform a worker that the template can be dismantled at present. Therefore, the situation that a worker removes the formwork in advance due to the fact that whether the interior of the concrete is solidified or not cannot be known, and consequently the concrete which is not completely solidified cracks due to the fact that the concrete loses support of the formwork is avoided, and in addition, the problem that an existing formwork is difficult to disassemble due to the too large size can be effectively solved through the multiple split formworks formed by splicing.

Description

Technical field [0001] The present invention relates to the technical field of stacked plate equipment, more particularly, to a removable prestressed reinforced truss stacked plate. Background [0002] Stacked panels are a type of building formwork that combines precast and cast-in-place concrete. Stacked board connection parts are welded by keel steel truss, when the concrete is poured, the connection parts of the stacked board are integrated with the steel bar and concrete, playing a more bonded and more firm role, in the construction stage, the stacked board body as a formwork for pouring concrete, the strength and stiffness of the formwork is provided by the steel truss welded with the keel. The construction phase uses stacked panels as formwork for pouring concrete, and the strength and stiffness of the formwork are supported by trusses welded together by steel bars. [0003] When pouring concrete on the formwork, depending on the external environment, such as high air humid...

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
