Problems solved by technology

However, it is inconvenient to make this type of formwork member, the production efficiency is low, it is not convenient for assembly line production, the cost is high, and the construction cost of the corresponding cast-in-place concrete hollow slab is high. Therefore, developing a new type of cast-in-place concrete hollow slab has urgent need

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, bottom and outrigger side. The upper slab, the side walls and the bottom enclose to form the polyhedral shuttering member, and the outrigger side stretches beyond at least one side of the bottom. The present invention features that at least one side outrigger side is superposed and has at least one prefabricated layer. The present invention is suitable for use in various kindsof 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, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. 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, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" pat...
