Hollow mold for filling cast-in-situ concrete

Abstract

A hollow matrix for cast-in-situ concrete filling comprises a hollow matrix (1) and outer walls (3) which form the hollow matrix (1) with a cavity (4) by enclosing. The hollow matrix is characterized in that the blanks of all outer walls (3) of the hollow matrix (1) are formed by a cement slurry blank, the blanks of the connected or separated outer walls (3) are cemented with each other at the joints which are cementing commissures (5) of the blanks edges, the number of the cementing commissures (5) is at least two, all the blanks edges are cemented to form the closed hollow matrix (1), the blank cementing joints of the outer walls (3) are provided with prefabricated units (7) supporting the matrix, an arm brace (2) and / or the out walls (3) are / is provided with a reinforcement (6), the reinforcement (6) is exposed of the hollow matrix (1). The hollow matrix has the advantages of easy manufacture, high production efficiency, excellent integrity, low cost, high strength and rigidity, convenient construction, being applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete hollow slabs, floors, roofs, walls, foundation slabs and bridges, especially being applicable 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 200410155270.6, 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 cost is high
