Abstract

The invention relates to a cast-in-place concrete hollow slab, comprising reinforced concrete (1), a light tyre foundation (2), wherein, the light tyre foundation (2) is wrapped in the reinforced concrete (1), and comprises a top plate (3), a plurality of periphery side plates (4), a lower bottom (5) and a hollow cavity (6); the top plate (3), the periphery side plates (4) and the lower bottom (5) are connected together to form the hollow cavity (6); a soft layer (7) is at least wrapped in one of the top plate (3), the periphery side plates (4) or the lower bottom (5), the cast-in-place reinforced concrete ribs (8) formed with reinforced concrete (1) are arranged among the periphery side walls (4) of the light tyre foundation (2). The invention is characterized in that the soft layer (7) is superposed on the external surface of the top plate (3), the periphery side plates (4) or the lower bottom (5), the top plate (3), the periphery side plates (4), or the lower bottom (5) are hard layers, a reinforced layer (10) is arranged on the external surface of the soft layer (7) for preventing the damage of the soft layer. Thereby, the invention is suitable for the hollow building roofs, house roofs, walling, foundation bottom plates and vierendeel bridges of the cast-in-place reinforced concrete or the prestressed reinforced concrete.

Description

[0001] This application is a divisional application of an invention patent application with an application date of November 10, 2005, an application number of 200510119894.7, and a title of "a cast-in-place concrete hollow slab". (1) Technical field [0002] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0003] At present, the cast-in-situ concrete hollow floor is a widely used floor structure. The soft permanent tire mold filled therein has various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled lightweight carcass, including The upper board, the surrounding side walls and the lower bottom form a polyhedral cavity, and the upper board, the surrounding side walls and the lower bottom contain fibe...
