Problems solved by technology

This formwork member has the characteristics of simple structure and convenient construction and transportation. After being applied to the floor, there is no force-bearing and force-transmitting member of the floor in the formwork member, especially when the formwork member is larger in size, the performance is better. Obviously, at the same time, the strength of the formwork components is not high, the production is inconvenient, the production efficiency is low, and the cost is high. Therefore, it is urgently needed to develop a new type of lightweight permanent casing for concrete filling.

Embodiment Construction

[0084] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0085]As shown in the accompanying drawings, the present invention comprises a lightweight carcass 1, the lightweight carcass 1 includes an upper shell 5, surrounding side shells 6, and a lower shell 7, and the upper shell 5, surrounding side shells 6, and lower shells 7 form a closed space. The cavity is characterized in that it also includes a through-hole pipe 8, which is arranged in the closed cavity of the lightweight carcass 1, and there is at least one existing hole formed by the through-hole pipe 8 in the light-weight carcass 1. Concreting is poured with hole 2 running through the upper and lower shell surfaces of lightweight carcass 1, through-hole pipe 8 is a hard prefabricated pipe, and the end of the prefabricated pipe is connected with prefabricated upper shell 5 or lower shell 7 or both. As shown in Figure 42, the lightweight permanent car...

Abstract

The present invention relates to a light permanent form for filling concrete. It includes a light form body, said light form body includes upper plate, peripheric side plate and lower plate, and said upper plate, peripheric side plate and lower plate can be combined together and made 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 light form body, said through hole tube is a hard prefabricated tube, and is used for forming concrete pouring hole. Said light 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 simple structure and convenient construction and transportation. After being a...
