Hollow matrix for cast-in-situs concrete filling

Abstract

A hollow matrix used for cast-in-place pouring comprises a hollow matrix (1) and a frame brace (2), the frame brace (2) is arranged at an external wall (3) at the bottom of the hollow matrix (1), and the external wall (3) forms the hollow matrix (1) with a hollow cavity (4). The present invention is characterized in thatat least one external wall (3) is the external wall of a laminated layer, a prefabricated layer (5) in the laminated layer is arranged in the inner layer of the external wall (3), an outer layer of the external wall (3) is a plastering layer (6), and the hollow matrix (1) is a square hexahedron. The present invention is easy to manufacture the hollow matrix, and has high production efficiency and low production cost; meanwhile, the hollow matrix has the advantages of simple structure, high strength, high toughness, deformation resistance, superior shockproof, convenient construction, fast construction rate, etc., thereby the present invention is applicable for a hollow board, a floor, a roof, a wall body, a foundation bottom board and a bridge of cast-in-place poured reinforced steel bar concrete or pre-stress reinforced steel bar concrete, in particular to a hollow floor without beams.

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 200410155278.2, 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 the production of this kind of building components is inconvenient, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high
