Description

A reinforced concrete three-dimensional load-bearing structure floor

This application is a divisional application of an invention patent application with an application date of April 30, 2002, an application number of 200510073675.X, and a title of "a reinforced concrete three-dimensional load-bearing structure floor".

(1) Technical field

The invention relates to a reinforced concrete three-dimensional load-bearing structure floor.

(2) Background technology

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 floors (solid and hollow), which better solve the problems of earthquake resistance, cracking and water seepage, but the construction of such floors is relatively difficult and the cost is relatively high . With the development of construction technology and economy, higher requirements are put forward for the quality of buildings. More and more buildings adopt the technology of cast-in-place concrete floors, especially the technology of cast-in-place concrete hollow floors. Patent No. 93206310.1 is a utility model patent for "formwork components", which discloses a prefabricated filling component for industrial and civil buildings with ribbed cavity floors. It consists of an upper bottom, a lower bottom and side walls. The side wall, the upper bottom and the lower bottom form a fully enclosed cavity polyhedron structure, and reinforcing ribs are provided in the formwork shell to enhance the self-supporting strength of the formwork components, and the formwork itself is not easy to be damaged. When it is applied to the ribbed cavity floor, according to the design requirements, the formwork components are placed on the supports between the floors, a certain gap is left between the formwork components, the steel bars are arranged, and cement is poured. Together with the reinforced concrete, the shell members form an overall floor structure with very smooth upper and lower surfaces. The formwork members are both internal molds and filling supporting components in the floor, which saves trouble and is convenient for construction. However, this kind of formwork member is relatively heavy in weight and consumes a lot of materials because the internal reinforcement ribs are plate-type reinforcement ribs. At the same time, the plate-type reinforcement ribs only consider that the top plate of the formwork is not easy to be damaged or only meet the construction pressure resistance. Load requirements, without considering the design of the formwork as the main load-bearing component, combined with the cast-in-place concrete structure to form a structural system under common stress, to resist various complex external forces such as tension, compression, shear, torsion, and vibration . The European patent application with the European patent number EP0884427A2, the international patent classification number E04B5/21, and the title "A better solution for the concrete boxes normally used in the fungiform pavements" involves the use of recycled plastics to manufacture concrete cavity formwork, and The formwork is applied in concrete road engineering and concrete floor engineering. The formwork is composed of an upper roof, surrounding side walls and lower bottom. The upper roof, surrounding side walls and lower bottom are connected with each other to form a polyhedral closed cavity. Five hollow conical rods with downward openings are arranged in the cavity. The rods are injection molded together with the lower bottom and surrounding side walls, and the upper top plate is connected with the surrounding side walls by bolts to form a whole plastic mold shell. 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 reinforced 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. .
