Concrete filled light mould member

Abstract

This invention is a concrete filling light tread mould component, comprising the tread body. The characteristics are: there is a transverse bottom rib fillister on the contacting part of the lower surface and at least one lateral face of the body, and at least one fillister that runs through the upper surface and the transverse bottom rib fillister on at least one lateral face, at least one vertical corner part of the same lateral face is the vertical inverted angle through the upper surface and the bottom rib fillister. In this way, when the tread model component is applied to the spot casting concrete building cover, closely arrange the light components and contain them in the reinforced concrete spot casting. In the fillisters of the lateral face and in the vertical inverted angle of the vertical corner part, the spot casting concrete forms the shear key of the building cover, and in the bottom rib fillister, the concrete forms the spot casting reinforced concrete rib connecting with the shear key. The construction is convenient and fast.

Description

(1) Technical field [0001] The invention relates to a lightweight tire mold member for concrete filling. (2) Background technology [0002] Beamless floor is currently the most widely used floor structure for cast-in-place concrete floors. It has the advantages of fast construction speed, small structural height, flexible division of indoor areas and no need for ceiling decoration. The lightweight permanent tire mold filled in it There are various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99232921.3, which the applicant applied for on March 10, 1999, is a utility model patent named "thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and two plugs. It is used as a lightweight permanent tire mold in beamless slabs. Another example is Liang Jun of Shijiazhuang City, Hebei Province. The patent No. ZL00203695.9 applied for on February 23, 2000, the formwork used in the utility...

AI Technical Summary

Problems solved by technology

However, whether it is a hollow tube or a box, after it is applied to the floor as a lightweight permanent matrix, it can form a one-way cast-in-place concrete rib hollow floor or a two-way cast-in-place concrete ribbed hollow floor, but it cannot form a shear bond type. Two-way hollow floor, although Guizhou University of Technology has applied for a utility model patent with a patent number of ZL97200102.6 named "Reinforced Concrete Shear Key Type Two-way Hollow Slab", which discloses a shear key type two-way hollow floor, It has the characteristics of light weight, mechanical performance, good seismic performance, and flexible division of building space, but its construction is very difficult, time-consuming and laborious
