A shuttering component

Abstract

The present invention relates to a formwork member comprising an upper plate (1), peripheral side walls (2) and a lower bottom plate (3). The upper plate (1), the peripheral side walls (2) and the lower bottom plate (3) are connected together and formed into a hollow cavity body. The lower bottom plate (3) is outwards extended from at least one peripheral side wall (2) and formed into a cantilever slab (4). The formwork member is characterized by that in the base layer of the upper plate (1), the peripheral side walls (2), the lower bottom plate (3) or the cantilever slab (4) at least one laminated layer (5) is arranged, the laminated layer (5) and the base layer are laminated to form a whole body, at the same time, in the upper plate (1), the peripheral side walls (2), the lower bottom plate (3) or the cantilever slab (4) a handling component (6) is arranged respectively. The closed cavity of the hollow cavity interior is provided with light material (19). The formwork member is applicable to various cast-in-situ concrete floor, roof, wall body, foundation base plate and buildings of road and bridge engineering. Specially, the formwork member is applicable to hollow beamless floor.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of October 1, 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
