Form unit

Abstract

A formwork member, comprising an upper plate (1), surrounding side walls (2), and a lower bottom plate (3), the upper plate (1), surrounding side walls (2), and lower bottom plate (3) enclosing a hollow body, The lower bottom plate (3) protrudes from at least one surrounding side wall (2) to form a pick plate (4), which is characterized in that the upper plate (1), the surrounding side walls (2), and at least one base layer of the lower bottom plate (3) are stacked There is at least one laminated layer (5), the laminated layer (5) is laminated with the base layer as a whole, and a stiffener (17) is arranged in the cavity, and the upper plate (1), the surrounding side walls (2), and the lower floor (3) or at least one of the picking boards (4) is provided with a carrier (6) for transporting construction, and the laminated layer (5) itself is a composite laminated layer laminated with at least two layers. It is suitable for hollow floors, roofs, walls, foundation slabs and hollow bridges of cast-in-place reinforced concrete or prestressed reinforced concrete, especially for hollow beamless floors.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of August 4, 2003, the application number of 200310100967.9, and the title of "a formwork component". (1) Technical field [0002] The present invention relates to a formwork member. (2) Background technology [0003] 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 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 ...

Problems solved by technology

However, such formwork components are inconvenient to manufacture, have low production efficiency, are inconvenient for assembly line production, and have high corresponding costs. At the same time, formwork components are inconvenient in the process of production, handling, and construction, which affects the construction speed. Therefore, the development of a A new type of formwork member is urgently needed
