Problems solved by technology

Similarly, this kind of plastic formwork only considers that the top plate of the formwork is not easy to be damaged or only meets the requirements of construction compressive loads. Although the hollow rods with conical downward openings can be conveniently stacked and transported, it does not consider the formwork. It is designed as the main load-bearing component and combined with the cast-in-place concrete structure to form a common three-dimensional force-bearing structural system to resist various complex external forces, especially the up-and-down pull force and horizontal shear force that cannot be resisted in the formwork.

Abstract

A load-bearing 3D hollow moulded member for reinforced concrete is composed of top slab, bottom slab, side walls and an internal cavity, which contains more than one supporting rod in various forms. At least one vertical rod has the cross section greater than that of a horizontal rod crossed with it. It is suitable for roof, floor, foundation slab, wall and bridge.

Description

[0001] This application is a divisional application of an invention patent application with an application date of April 30, 2002, an application number of 02117551.9, and a title of "a three-dimensional load-bearing formwork for reinforced concrete". (1) Technical field [0002] The invention relates to a three-dimensional load-bearing formwork for reinforced concrete. (2) Background technology [0003] At present, most buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid ...
