Hollow carcass for cast-in-situ concrete stuffing

Abstract

The invention discloses a hollow matrix used for filling field casting concrete, which comprises a hollow matrix (1) and a supporting lug (2). The supporting lug (2) is arranged at the outer wall (3) of the bottom of the hollow matrix (1); the outer wall (3) is enclosed to form the hollow matrix (1) with a cavity (4). The hollow matrix is characterized in that at least one outer wall (3) is laminated outer wall; a precast layer (5) arranged in the laminated outer wall is positioned in the inner layer of the outer wall (3), the outer layer of which is a field smearing layer (6); the precast layer (5) or / and filed smearing layer (6) of outer wall (3) is provided with a reinforcer (10), and the cavity(4) is provided with a stiffener (17). The hollow matrix is applicable to field casting reinforced concrete or prestressed reinforced concrete hollow slabs, floors, roofs, wall bodies, foundation base plates and bridges, and is especially applicable to the hollow girderless floors.

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
