Steel reinforcement structure of bubbledeck slab elements and procedure of manufacturing bubbledeck slab elements

Abstract

The invention relates to the steel reinforcement structure of hollow concrete deck and the procedure to manufacture such kind of bubbledeck. The steel structure of bubbledeck element includes upper steel mesh (110); lower steel mesh (120) at bottom place and in parallel to the upper steel mesh (110); hollow plastic balls (130) are arranged between upper mesh (110) and lower steel mesh (120) creating many ranges of hollow plastic balls placed in parallel with each other in horizontal and vertical directions; many connectors (140) to joint upper steel mesh (110) and lower steel mesh (120); formwork system (150) is fit into lower steel mesh (120), in which each connector (140) is connected to a steel bar (111) of a grid cell (112) where no hollow plastic bodies (130) of upper steel mesh (110) is fixed to a steel bar (121 ) in a skew angle of a lower corresponding grid cell (122) where no hollow plastic balls (130) of lower steel mesh (120) is fixed, creating a diagonal connecting system composes of many connectors (140) of sinuous shape go along with the longest side of deck element, and formwork system (150) consists of many connector parts (160) which are arranged into grid cells (122) of the lower steel mesh (120) separated by 3 grid cells (122) in each grid range and in alternate positions in two adjacent grid cell range separated by 2 ranges of grid, and many formwork plates (170) of designed size which can be removed or fit into connector parts (160) by using bolts and nuts. The procedure of manufacturing bubbledeck element includes the step of manufacturing steel reinforcement of deck element, step of installing the steel reinforcement, step of prepairing before casting the concrete, step of casting the concrete, steps of inspection after casting concrete and the final step is finishing the procedure.

Description

technical field [0001] The invention relates to a reinforced structure of a hollow concrete panel, in particular to a reinforced structure of a hollow concrete panel and a method for manufacturing a hollow concrete panel by using the reinforced structure, which has the characteristics of lower cost, labor saving and easy execution. Background technique [0002] Nowadays, hollow concrete panels are widely used in the field of civil construction, especially in multi-storey buildings, because it has many advantages over normal solid concrete panels. Because the hollow plastic body is used to replace unnecessary concrete, the hollow panel saves up to 30-40% of the steel consumption and 40-50% of the concrete consumption compared with the solid concrete panel. However, the steel structure of the hollow concrete panel is complicated, and installation requires a lot of time and money, because it is quite difficult to connect the steel bar and the plastic hollow body. In addition, ...

AI Technical Summary

Problems solved by technology

[0005](2) The construction of template system requires a lot of money;

[0006](3) Requires specialized welding machine and a lot of time to weld spacers to connect lower and upper mesh

In addition, excessive welded joint construction may alter the properties of the steel and reduce the durability of the panel construction; and

[0007] (4) Since the plastic spheres are hollow, these plastic bodies will float to the surface when the concrete is poured, causing thrust and an unstable structure

[0009](1) It takes a lot of money to build a factory or studio to manufacture panel components;

[0010](2) Transporting these structures to the job site is expensive and the thin concrete layers may crumble during transport;

[0011] (3) Since hollow concrete panel structures are heavy, it is necessary to use heavy cranes to lift these The location is also very difficult;

[0013] (5) Since the casting time of the thin concrete layer is not the same as that of casting the concrete at the site, there is no integrity between them

This reduces the technical efficiency and durability of hollow concrete panels
