Cast-in-situ concrete filled hollow stuffing

Abstract

A hollow roughcast for the filling of cast-in-place includes a hollow roughcast, an outside wall to be closed to form a hollow roughcast with a cavity characterizing that a movable hanging ring passing through the outside wall is set on the wall, so it's very easy for the hollow roughcast to be transported in construction and the hanging ring will not be broken or harm the hollows roughcast on it when the roughcast are hoisted or stacked.

Description

(1) Technical field [0001] The invention relates to a hollow matrix for filling cast-in-place concrete. (2) Background technology [0002] At present, the cast-in-place concrete floor is a widely used floor structure. The lightweight permanent tire mold filled in it has various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, is called the utility model patent of "combined concrete concealed rib floor cover", and a formwork member is disclosed in its specification sheet. It can be solid or hollow, and its shape can be made into rectangle, circle, polygon and other shapes according to design requirements. Another example is the utility model patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, entitled "fiber-reinforced thin-walled components for reinforced concrete filling", which discloses a thin-walled formwork componen...

AI Technical Summary

Problems solved by technology

These formwork components are inconvenient during transportation and construction, which affects construction efficiency. Therefore, it is urgently needed to develop a new type of hollow matrix for filling in-situ concrete.
