Mould shell construction unit for on site pouring concrete

Abstract

A present pouring reinforced concrete model shell component , it includes the light quality material component (1), whose characteristic is that it contains peripheral side wall (2), the bottom (3), close cover (8) , the peripheral side wall (2), the bottom (3) and the close cover (8) draws the light quality material component (1) in the cavity which is surrounded by them, the peripheral side wall (2) and the bottom (3) is a whole component. It is applied to different occasions such as various present pouring reinforced concrete building cover , house cover , basis bottom board , the wall body , the spandrel-braced bridge, big volume concrete project etc.

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...

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
