Description

[0001] This application is a divisional application of an invention patent application with an application date of March 31, 2003, an application number of 03118222.4, and a title of "a lightweight permanent tire mold for filling cast-in-place reinforced concrete". (1) Technical field [0002] The invention relates to a cast-in-place reinforced concrete floor filled with lightweight permanent tire molds. (2) Background technology [0003] 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 reinfo...

Problems solved by technology

Japanese patent (JP2001214562) discloses a lightweight carcass, on which there are holes through the upper and lower surfaces, so that after this lightweight carcass is applied to the cast-in-place concrete floor, the floor can be formed in the tire mold However, the bond between the lightweight matrix and cast-in-place concrete is poor, and the integrity of the formed floor is poor. Therefore, a new type of cast-in-place reinforcement filled with lightweight permanent tire molds is developed. Concrete floor, to improve the performance of the floor, has been urgently needed
