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.

Embodiment Construction

[0127] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0128] As shown in the accompanying drawings, the present invention comprises an upper top plate 1, surrounding side walls 2 and a lower bottom 3, and the upper top plate 1, surrounding side walls 2 and lower bottom 3 are connected to each other to form a polyhedron closed cavity 4, and in the cavity 4 there are at least More than one bar 5, the present invention is characterized in that the bar 5 is a curved bar, a broken line bar, a cable, a straight bar with a constant section, a solid straight bar with a variable section, a hollow bar with an upper opening or a combination thereof, or a hollow straight bar with a variable section With the combination of the above-mentioned rods, there is a hanger 39 exposed from the center position of the top plate 1 on the formwork. Fig. 1 is a schematic structural view of Embodiment 1 of the present invention, 1 i...

Abstract

The stereo force bearing shuttering for reinforced concrete includes upper plate, side walls and lower bottom, which are connected to constitute closed polyhedral cavity. The cavity has at least one rod inside it. The present invention features that the rod inside the shuttering cavity is curved rod, bent rod, cable, prismatic straight rod, varying cross section straight rod, hollow rod or their combination; and there is hanging part extending the central position of upper plate. The present invention is suitable for floor slab, foundation slab, wall, bridge and other hollow concrete structure, and is especially suitable for hollow concrete floor slab engineering.

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 ...
