Problems solved by technology

However, the lower slab of this floor slab is a prefabricated thin slab, and there are joints between them, so the integrity is poor. If the lower slab is a cast-in-place reinforced concrete slab, although the integrity is good and there is no problem of joints, the construction is inconvenient , the cast-in-place concrete is not dense, and problems such as honeycomb pits are prone to occur. Therefore, it is urgently needed to develop a new type of formwork member

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] As shown in the accompanying drawings, the present invention includes an upper plate 1 and a surrounding side wall 2, and the upper plate 1 and the surrounding side walls 2 form an open basin-shaped member, which is characterized in that the upper plate 1 of the described basin-shaped member is open. There is a skylight 3 for carrying out concrete construction work in the lower chamber of the upper plate 1, and the skylight 3 has a movable window member 32 for reducing the size of the window. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding side wall, and 3 is a skylight. In the following accompanying drawings, those with the same number have the same description. As shown in Figure 1, it includes an upper plate 1 and a surrounding side wall 2, the upper plate 1 and the surrounding side walls 2 form an open basin-shaped membe...

Abstract

The present invention relates to a kind of form member. It includes upper plate and peripheric side wall. Said upper plate and peripheric side wall can be combined together and formed into an open basin-shaped member. It is characterized by that on the upper plate a top window is cut, said top window can be used for making concrete construction operation in the lower cavity of said upper plate, in the top window position is set a movable window-contracting component capable of contracting window size, so that said form member 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 present invention relates to a formwork member. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during construction, which not only...
