Problems solved by technology

However, there is no reinforcing structure in this cavity formwork member, so the overall strength and rigidity of the cavity formwork member are poor, and the phenomenon of damage to the cavity formwork member is prone to occur. In the cast-in-place concrete hollow slab, it cannot be compared Participate well in the force bearing and transmission of cast-in-place concrete hollow slabs

Abstract

The in-situ cast hollow concrete slab includes reinforced concrete and shuttering members ranged at intervals and wrapped with the in-situ cast reinforced concrete. The shuttering member includes upper slab, side walls and bottom, which enclose to form polyhedral shuttering member and contain reinforcement in at least one of the parts. The present invention features that the in-situ cast hollow concrete slab includes also at least one post-cast rod formed on the prefabricated upper slab, side walls or bottom. The present invention is suitable for use in various kinds of in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, the cast-in-place concrete hollow slab is a widely used floor structure. The lightweight permanent tire mold filled in it includes 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 formwork member, including an upper plate, The surrounding side walls, the lower bottom, the upper plate, the surrounding side walls, and the lower bottom form a polyhedral cavity, and the upper plate, the surrounding side walls, and the lower bottom contain fiber reinforcements. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442...
