Problems solved by technology

This formwork member has the characteristics of high strength, simple structure, and convenient construction and transportation. However, when the formwork member is applied to the construction process of the cast-in-place concrete hollow floor, it is difficult to pour and tamp the cast-in-place concrete under the lower bottom of the formwork member. It is difficult to form compactly, especially when the size of the formwork components is large, the performance is more obvious. Therefore, it is urgent to develop a new type of cast-in-place concrete hollow slab.

Abstract

The in-situ cast reinforced concrete floor slab includes reinforced concrete and light casing coated inside reinforced concrete. It includes also pipe set inside the closed cavity of the light casing to form hole for in-situ casting concrete and penetrating the upper and the lower surfaces of the light casing and funnel-shaped cover plate for the hole. The present invention is suitable for 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 floor is a widely used floor structure. The lightweight permanent tire molds filled in it include 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. This formwork member has the characteristics of high strength, simple structure, and convenient construction and transportation. However, when...
