Problems solved by technology

However, the flexural strength of the all-steel single-layer thick steel plate is small, and the bottom plate of the reinforced concrete structure is large in volume and weight, which is extremely inconvenient for construction and transportation; while the steel-concrete bottom plate of the single box room has poor relative deflection resistance and complicated construction technology.

Embodiment Construction

[0017] see figure 1 and figure 2 , the base plate in this embodiment is composed of two or more rectangular tubes 1 arranged side by side, fastened by means of connectors penetrating transversely, and the connecting surfaces between adjacent rectangular tubes are welded to form an integrated structure. The cavity of each rectangular tube Injection concrete in the body. Specifically, the rectangular tubes 1 arranged in parallel are evenly distributed with corresponding threaded holes or through holes along their longitudinal direction, and are fastened by means of screw rods 2 connected in series. The nuts at both ends of the screw rods are also provided with protective decorative caps 3 . The through holes can be configured as slot-shaped holes, so as to reduce the precision requirements for connecting the rectangular tubes and improve the processing efficiency of the bottom plate.

[0018] Two rows of threaded holes or through holes are arranged on the same side of the rec...

Abstract

The invention discloses a reinforced concrete multi-chamber beam slab bottom plate and a manufacturing technology thereof. The bottom plate is of an integrated structure formed by two or more rectangular pipes which are arranged side by side and fastened through connecting pieces and welding of connecting seams between the adjacent rectangular pipes, and cavities of all the rectangular pipes are filled with concrete in a pressing mode. According to the technical scheme, the multi-chamber structure is adopted in the bottom plate, the side walls of the rectangular pipes perform the function of reinforcing ribs, and the bending strength of the bottom plate is increased.

Description

technical field [0001] The invention relates to a beam-slab base structure, in particular to a steel-concrete multi-chamber beam-slab base and its processing technology. Background technique [0002] Steel bridge bottom plates are mostly thick steel plates or reinforced concrete bottom plates, and single-chamber box-type steel-concrete bottom plates are also used. However, the bending strength of the all-steel single-layer thick steel plate is small, and the bottom plate of the reinforced concrete structure is large in volume and weight, which is extremely inconvenient for construction and transportation; while the steel-concrete bottom plate of the single-box room has poor relative deflection resistance and complicated construction technology. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel-concrete multi-chamber beam-slab bottom plate with simple processing technology, good bending resistance and high r...
