Steel reinforced concrete stereo force bearing structure floor slab

Abstract

The stereo bearing reinforced concrete structure floor slab includes in-situ cast reinforced concrete upper plate, separately arranged hollow shutterings and in-situ cast reinforced concrete ribs in between, cast into one integral. Each of the hollow shutterings includes upper plate, side walls and bottom plate connected mutually to constitute a closed polyhedral cavity with rods inside it, and the upper plate and the side walls are superposed separately with the in-situ cast reinforced concrete upper plate and the in-situ cast reinforced concrete rib. The present invention features that the rods inside the cavity are curved rod, bent rod, cable, straight rod, hollow rod with upper opening or their combination, and that the central anchoring rib of the upper plate is exposed and fixed onto the hollow reinforcing rib.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete three-dimensional load-bearing structure floor. (2) Background technology [0002] 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, ...

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 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.
