Embodiment Construction

[0019] Embodiment 1 of the cast-in-place concrete filling matrix of the present invention: as Figure 1 to Figure 4 As shown, the cast-in-place concrete filling carcass is mainly composed of a carcass base 1 and an inflatable inner tank 2 in the carcass base 1, wherein the inner cavity of the carcass base 1 is a square inner cavity, and the corresponding inflatable inner tank 1 The shape is also square, and the inflatable liner 2 is directly embedded in the carcass base 1, so that the carcass base 1 can seal the inflatable liner 2 in it, that is, when the staff pours the carcass base 1, the The inflatable liner 2 and the carcass base 1 are integrally casted, and the material used for pouring the carcass base 1 is foamed concrete, so that the box body of the carcass base 1 is a spongy porous body composed of concrete entities and foam holes , and the outer surface of the carcass base 1 is provided with a waterproof layer 3 made of waterproof paint.

Abstract

The invention relates to a matrix for filling cast-in-situ concrete. The matrix comprises a matrix base body and an aerating liner embedded in the matrix base body; and the aerating liner is fixedly sealed in the matrix base body. The inner part of the matrix base body is internally provided with the aerating liner, and the aerating liner is directly embedded in the matrix base body. In use, the aerating liner can play the role of supporting the peripheral wall of the matrix from the inner part of the matrix, therefore, the problem that the peripheral wall of the matrix is sunken inwards in use is avoided; a shell of the aerating liner can be only burned when the aerating liner is directly contacted with open fire, so that the burning intensity of the aerating liner is low, the burning time is relatively short, and further, the problem that in the prior art, a filler in the matrix for filling the cast-in-situ concrete can ignite the other matters in the process of burning is solved.

Description

technical field [0001] The invention relates to a matrix for filling cast-in-place concrete in the technical field of building materials. Background technique [0002] During the manufacture or construction of reinforced concrete hollow slabs, filling some lightweight filler blocks with a specific gravity smaller than concrete in the concrete can reduce the overall weight of the concrete hollow slab and improve the effects of concrete maintenance, heat insulation and sound insulation. Hollow thin-walled boxes are mostly used in construction, but since there is no supporting structure between the top and bottom surfaces of the carcass matrix, the strength of the carcass matrix is ​​limited. During transportation and construction, the carcass matrix is ​​easily broken due to trampling or collision. crack or collapse. [0003] The Chinese invention patent with application number 200720187692.8 discloses a carcass for filling cast-in-place concrete. The carcass is filled with p...
