Description

(1) Technical field

[0001] The invention relates to a lightweight permanent carcass for filling cast-in-place reinforced concrete. (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 fo...
