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 at least one fillister through the upper and the lower surfaces on at least one lateral face of the body, at least one vertical corner part of the same lateral face is an vertical shadow angle through the upper and the lower surfaces, the transverse corner part of the bottom side of the same lateral has the transverse shadow angle that intersects rightly or slantingly with the vertical shadow angle or the 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 fillister of the lateral face and the in the vertical shadow angle at the vertical corner part, the spot casting concrete forms the shear upset of the building cover; in the transverse shadow angle of the transverse corner part of at bottom side of the body, the concrete forms the spot casting concrete reinforcing rib connecting with the shear upset. The construction is convenient and fast.

Description

(1) Technical field [0001] The invention relates to a 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 model paten...

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
