Integrated steel bar formwork-free cast-in-place concrete beam

Abstract

The invention discloses an integrated steel bar formwork-free cast-in-place concrete beam which comprises a U-shaped beam shell, a steel bar framework and a tie piece. The U-shaped beam shell comprises a U-shaped groove used for containing the steel bar framework, the U-shaped groove comprises two opposite side face plates and a bottom face plate, one side edges of the two side face plates are fixed to the bottom face plate, the steel bar framework is matched with the U-shaped groove so that the steel bar framework can be placed on the bottom face plate, the height of the steel bar framework in the direction perpendicular to the bottom face plate is larger than the height of the side face plate in the direction perpendicular to the bottom face plate, the length of the steel bar framework in the extending direction of the steel bar framework is larger than that of the U-shaped groove in the extending direction of the U-shaped groove, and the two ends of the tie piece are fixed to the two opposite side face plates. The cast-in-place concrete beam can avoid four procedures of formworks, steel bars, pipelines and plastering which are low in efficiency during on-site construction in theprior art.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a form-free cast-in-place concrete beam with integrated steel bars. Background technique [0002] In the traditional cast-in-place concrete structure engineering, the on-site construction efficiency of the panels and reinforcement sub-projects is very low, and the average daily output value does not exceed 2,300 yuan; the on-site construction efficiency of door and window installation, block filling walls, external insulation and painting is even lower , the average daily output value does not exceed 1,000 yuan; while the on-site construction efficiency of the concrete sub-item is very high, the highest average daily output value can reach 20,000 yuan. At present, my country's construction industry is entering the stage of vigorously promoting the industrialization of construction, but the existing prefabricated structure system changes the concrete with high daily ...

Problems solved by technology

At present, my country's construction industry is entering the stage of vigorously promoting the industrialization of construction, but the existing prefabricated structure system changes the concrete with high daily average output value to the factory, and the panel, steel bar, external insulation and painting with low output value Most of them are left on site, resulting in slow progress of the construction period and a significant increase in construction costs

In addition, after adopting PC components, the sub-item of prefabricated component installation has been added. On-site construction needs to be cross-operated, the process will increase, and the difficulty of management will increase. Moreover, the assembly integral frame structure system and the assembly integral frame cast-in-place are currently widely used. The actual assembly level of the shear wall structure system is generally not high, and a large number of panels, plastering, masonry, steel bars, e
