Hollow mold for filling cast-in-place concrete

Abstract

A hollow matrix used for filling cast-in-place concrete includes a hollow matrix (1) with an empty cavity (4) which is formed by the enclosing of an outer wall (3); the invention is characterized in that the hollow matrix (1) is a square hexahedron; the shape of the horizontal section of the hollow matrix (1) is a square quadrilateral; a cementation belt (5) jointed with the side of the blank body of the outer wall (3) is arranged on the upper plate of the hollow matrix (1); a reinforcement (10) is arranged in the cementation belt (5). The hollow matrix used for filling cast-in-place concreteis suitable for being used on the hollow plates, floors, roofs, walls, foundation bottom boards and bridges of cast-in-place reinforced concrete or prestressed reinforced concrete and is suitable forbeing used on hollow floors without beams in particular.

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 200410155277.8, 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 lay out during design and construction; at the same time, it is inconvenient to make building components during production, the production efficiency is low, it is not convenient for assembly line production, and the cost is high
