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 reinforced concrete cubic bearing die shell includes a top plate, a sidewall and bottom to be connected to become a polyhedron sealed cavity with more than one rods in it characterizing that the rods are curved rods, fold rods, cable, uniform section straight rods, non-uniform solid straight rods, a hollow rod with top open-end or its combination or a non-uniform section hollow straight rod combined with the above mentioned rods, which are connected to a sealed ring.

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 ...
