Problems solved by technology

But for its hollow, it is often relatively difficult to make, needs more molds, and the cost is relatively high; and the solid light material member, then because the light material is plant straw, etc., its strength is not enough, there is no protective layer , easy to be damaged during handling and construction, so the cost is relatively high

Embodiment Construction

[0035] The present invention will be further described below in conjunction with drawings and embodiments.

[0036] As shown in the drawings, the present invention comprises a lightweight material component 1, which is characterized in that it also includes a surrounding side wall 2 and a lower bottom 3, and the surrounding side wall 2 and the lower bottom 3 wrap the lightweight material component 1 around the surrounding side wall 2 and the lower bottom 3. In the cavity surrounded by the lower bottom 3, there are stiffeners 6 or / and stiffeners 7 or ribs 5 in the lightweight material component 1 and / or between the lightweight material component 1 and the surrounding side walls 2. figure 1 It is a schematic structural view of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a lightweight material component, 2 is a surrounding side wall, and 3 is a lower bottom. In each accompanying drawing, those with the same number have the same description. Such as ...

Abstract

The cast-in-place reinforced concrete formwork component includes light stuffing coated in a hollow cavity formed by sidewalls and bottom board. The reinforcing rib or / and member or bar is in the light stuffing component and / or between the light stuffing component and sidewalls. The present invention is suitable for various cast-in-place hollow floor slab, roofing, base slab, wall, open web bridge and large volume concrete project.

Description

[0001] This application is a divisional application of an invention patent application with an application date of March 11, 2003, an application number of 200510129255.9, and a title of "a formwork component for cast-in-place concrete". (1) Technical field [0002] The invention relates to a formwork component for cast-in-place concrete. (2) Background technology [0003] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow 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 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 in the gaps, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buil...
