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, complex structure, time-consuming and laborious

Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0058] As shown in the accompanying drawings, the present invention includes reinforced concrete 1, lightweight tire mold member 2, and the lightweight tire mold member 2 is wrapped in reinforced concrete 1, and is characterized in that there is a At least one groove 3 that runs through the upper and lower surfaces, at least one vertical corner on the same side is a vertical chamfer 4 that runs through the upper and lower surfaces, lightweight tire mold members 2 are arranged closely, and cast-in-place reinforced concrete 1 is The groove 3 or the vertical chamfer 4 forms a cast-in-place concrete shear pier 5, and the corresponding cast-in-place concrete slab forms a shear pier-type cast-in-place concrete slab. The corner part has a horizontal inner corner 6 that is orthogonal or oblique to the vertical chamfer 4 or the groove 3, and the cast-in-place co...

Abstract

A concrete board casting on-site comprises a light weight inner mold and an outer reinforcement concrete. There is at least one vertical flute in at least one vertical side of the mold and a vertical chamfer on at least one of the corners on the same side. The molds are arrayed tightly side by side. At casting, concrete forms share force piers in the vertical flutes and chamfers. On the same side with the flute, there is a horizontal flute to the mold bottom. At casting, reinforcing bars are formed at the cross of horizontal flutes with the vertical flutes and chamfers.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete board. (2) Background technology [0002] The cast-in-place concrete slab is currently the most widely used floor structure. 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 has various hollow tubes. And boxes, 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 patent named "combined concrete concealed ri...
