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 lightweight permanent carcass for concrete filling.

Abstract

The present invention relates to a light-weight permanent form for filling concrete. It includes a light-weight form body, said light-weight form body includes upper plate, peripheric side plate and lower plate which are connected together and formed into a closed hollow cavity. It is characterized by that it also includes a through hole tube, said through hole tube is placed in the closed hollow cavity of said light-weight form body. Said light-weight permanent form can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation bedplate and open-web bridge, etc.

Description

(1) Technical field [0001] The invention relates to a lightweight permanent carcass for concrete filling. (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 transportatio...
