Abstract

The invention discloses a thin wall box used for filling the cast-in-situ concrete and a manufacture method of the thin wall box and a die used for manufacturing, wherein, a framework internal mold a main body is a hollow square body structure of single face opening is filled in the thin wall box by the invention, the framework internal mold forms a cavity in the thin wall box, to ensure that each wall face of the thin wall box can be painted once or formed by pouring, the splicing wall plate or the casing body are not required, the framework internal mold is taken as the die to be used when being formed in the thin wall box, the mold is not removed when the pouring is formed and also can be taken as a reinforced material, simultaneously, the framework internal mold self in the thin wall box also has the function of the sound isolation and the sound absorption. Each wall plate of the thin wall box of the invention is combined tightly, the damage and the collapse are not easy, the invention has the advantages that the formation is easy as well as the structure is firm.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thin-walled box for filling cast-in-place concrete, a manufacturing method thereof and a mold for manufacturing the same. Background technique [0002] In the production or construction process of reinforced concrete hollow slabs, some lightweight materials are filled in the concrete to reduce the weight of the structure and improve the thermal insulation, heat insulation, and sound insulation effects of the concrete. Hollow boxes are often used in the filling blocks. , this hollow box is also provided with concrete pouring holes through the upper and lower surfaces of the hollow box body to facilitate pouring and improve mechanical performance. However, the existing hollow boxes are composed of more than two wall panels or prefabricated shells, which are easily damaged or even collapsed during transportation and installation. Larger hollow boxes are more likely to b...
