Prestress sheet assembling type prefabricated composite floor slab

Abstract

The invention provides a prestress sheet assembling type prefabricated composite floor slab which comprises a lower bottom board, side stop modules, support components, an upper bottom board and string columns. By the adoption of the prestress sheet assembling type prefabricated composite floor slab, the problems that in the manufacturing process of an existing composite floor slab, side edges ofthe existing composite floor slab need to be enclosed by wooden boards so as to prevent poured cement from overflowing, however, plenty of the cement still can overflow through the bottom ends of thewooden boards adopted for enclosing, thus the cement is wasted, furthermore, the cement can be bonded to the wooden boards after setting, a worker needs to use a hammer or other tools for separating the wooden boards from the manufactured composite floor slab, the cement of the composite floor slab cracks in the separation process of the wooden boards, and the strength of the composite floor slabis further affected can be solved.

Description

technical field [0001] The invention relates to the technical field of prefabricated building materials, in particular to an assembled prefabricated laminated floor slab of prestressed thin plate. Background technique [0002] The laminated slab is an assembled integral slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The laminated floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for decoration of the facing layer, and is suitable for high-rise buildings and large-bay buildings that require high overall rigidity. [0003] The side of the existing laminated floor slab needs to be surrounded by wooden boards to prevent the poured cement from overflowing, but the bottom end of the boards used to surround the board will also cause a large amount of cement overflow to form a waste of cement. Condensation will stick to the wood boards. It is necessary to manually use a hammer to se...

AI Technical Summary

Problems solved by technology

[0003] The side of the existing laminated floor slab needs to be surrounded by wooden boards to prevent the poured cement from overflowing, but the bottom end of the boards used to surround the board will also cause a large amount of cement overflow to form a waste of cement. Condensation will stick to the wood board, and it is necessary to manually use a hammer to separate the wood board from the finished laminated floor. During the process of separating the wood board, the cement of the laminated floor will be cracked, which will further affect the strength of the laminated floor.

[0004] In order to ensure the structural strength of the laminated floor slab and avoid the waste of cement in the process of pouring cement; therefore, the present invention provides a prestressed thin plate assembled prefabricated laminated floor slab
