Hollow mold for filling cast-in-situ concrete

Abstract

Disclosed is a hollow matrix for filling cast-in-situ concrete, which comprises a hollow matrix (1), wherein the hollow matrix (1) is formed by enclosing outer walls (2), and the inside of the hollow matrix is a cavity (3). The hollow matrix is characterized in that the side outer walls (2) of opposed face of the hollow matrix (1) is formed by soft and hard superposing, cementing and hardening a precast slab wall (4) and a slurry blank (5), the hollow matrix is adapted to hollow slab, floor, roof, wall, base plate and bridge made by cast-in-situ reinforced concrete or prestressed reinforced concrete, especially suitable for hollow girderless floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 11, 2004, an application number of 200410155218.0, 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...
