Hollow mold for filling cast-in-situ concrete

Abstract

A hollow matrix for cast-in-situ concrete filling comprises a hollow matrix (1) and an arm brace (2), wherein, the arm brace (2) is arranged on outer walls (3) of the hollow matrix (1), the arm brace (2) is a split arm or a movable arm, and the hollow matrix (1) with a cavity (4) is formed by enclosing the outer walls (3). The hollow matrix is characterized in that the hollow matrix (1) is a hexahedron; the hollow matrix (1) is formed by closing an opening of a basin-shaped blank (6) by a prefabricated outer wall (5), a prefabricated outer wall (2) is a top outer wall, the prefabricated outer wall (5) is superposed with an applied-in-situ layer (7), a pentahedral blank of the basin-shaped blank (6) is an integrated connected blank, the blank rims of the pentahedral blank are jointed and cemented, and a joint forms a cementing zone (8), the applied-in-situ layer (7) is internally provided with an reinforcement (12). The hollow matrix is applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete hollow slabs, floors, roofs, walls, foundation slabs and bridges, especially to hollow flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 2, 2004, an application number of 200410155274.4, and a title of "a hollow matrix for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a hollow matrix for filling cast-in-place concrete. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a...

Problems solved by technology

But when this kind of hollow carcass is applied to the floor construction, the hollow carcass cannot be accurately arranged in the middle layer of the floor, which affects the construction quality of the floor

For this reason, the patent No. is ZL01215092.4, and the name is "building component" utility model patent. The disclosed building component is a polyhedron, which can be hollow or solid. In order to ensure that this building component is applied to the floor It is arranged in the middle layer of the floor, and the outer wall of the polyhedron is provided with protruding legs, so that when the floor is poured, the legs can ensure that the hollow multi-faceted main cavity is just at the middle layer of the floor. , so as to better solve the above problems, but this kind of building components is inconvenient to make during production, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high
