Problems solved by technology

However, it is inconvenient to make this type of formwork member during production, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high. At the intersection of cast-in-place concrete ribs, the stress of the floor is more complicated, the stress is more concentrated, and cracks are easy to occur, or even cracked and damaged. Therefore, it is urgent to develop a new formwork component

Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0066] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and a lower bottom plate 3, and the upper plate 1, surrounding side walls 2, and lower bottom plate 3 form a hollow body, which is characterized in that the upper plate 1, the surrounding side walls 2 or at least one base layer of the lower bottom plate 3 is laminated with at least one laminated layer 4, and the laminated layer 4 is laminated with the base layer as a whole, and is arranged as a lateral inner corner 5 at at least one lateral corner of the cavity. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the upper plate, 2 is the surrounding side wall, 3 is the lower bottom plate, 4 is the superimposed layer, and 5 is the horizontal inner corner. In the fo...

Abstract

The invention is a kind of formwork component; it includes the upper board, around sidewalls, the subjacent board, which three combines the hollow cavity, the character lies in: at least one base layer of the upper board, around sidewalls and the subjacent bottom board has at least a piece of folding layer, the folding layer and the base layer combines the integer, there sets a transverse inside corner at one or more transverse cross of the hollow cavity. Thus, the formwork component is easy to be produced, the producing efficiency is high, and the correspondent cost is low. The inside corner part of the formwork component forms the reinforcing bar to concrete pouring, thus it can eliminate the stress concentration, prevent from crack generating, improves the mechanical performance of building cover, and applies to concrete the hollow house floor.

Description

(1) Technical field [0001] The present invention relates to a formwork member. (2) Background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and 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" patent application f...
