Hollow tire body for cast-in-situ concrete filling

Abstract

Disclosed is a hollow matrix for filling cast-in-place concrete, comprising a hollow matrix (1) and support pins (2). The support pins (2) are arranged on a bottom exterior wall (3) of the hollow matrix; and exterior walls (3) are enclosed to form the hollow matrix (1) with a hollow cavity. The hollow matrix is characterized in that at least one of the exterior walls(3) is a laminated exterior wall; the precast layer in the laminated layer is arranged at the internal layer of the exterior wall; the external layers of the exterior walls(3)are cast-in-place layers(6); the bottom exterior wall(3)at the top or the bottom is a laminated exterior wall; a reinforcement piece (17) which is a precast hollow pole is arranged in the hollow cavity(4), with the two ports respectively communicated with the outside of the exterior walls at the top and the bottom, forming a communicated hole(16); an exposed reinforcement member (10)of the precast layer(5)is fixedly anchored in the cast-in-place layers of the external layers. The hollow matrix is applicable to cast-in-place or prestressed reinforced concrete hollow boards, floors, house roofs, wall bodies, foundation soleplates and bridges and is particularly suitable for hollow girder-less 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
