Hollow mold for filling cast-in-situ concrete

Abstract

A hollow matrix for cast-in-situ concrete filling comprises a hollow matrix (1), an arm brace (2) which is arranged on the outer wall (3) on the bottom surface of the hollow matrix (1), and the outer wall (3) forms the hollow matrix (1) with a cavity (4) by enclosing. The hollow matrix is characterized in that the hollow matrix (1) or / and the arm brace (2) is / are provided with a locking element (5) which comprises a self-locking hole (6) and a self-locking strip or band (7), the locking element (5) is anchored in the hollow matrix (1) by an anchoring element (8), or the locking element (5) is connected with the anchoring element (8) which is anchored in the hollow matrix (1), the locking element (5) penetrates and extends out the arm brace (2), and the arm brace (2) is made of a mortar hard brace, or a concrete brace, or a plastic brace. 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 August 26, 2004, an application number of 200410155256.6, 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 p...

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 number is ZL01215092.4, and the utility model patent titled "Building Components" discloses a building component that is a polyhedron, which can be hollow or solid. 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 in the design and construction, and when it is applied to the cast-in-place concrete hollow floor, it is prone to misalignment in the horizontal direction of the building components, which affects the hollow floor. Construction quality, and affect construction efficiency
