Fabricated building transfer floor steel bar positioning fixture and construction method thereof

Abstract

The invention discloses an assembly type building transfer floor reinforcing steel bar positioning fixture and a construction method thereof.The positioning fixture comprises a long-strip-shaped clamping plate, a plurality of reinforcing steel bar inserting grooves and vibrating holes are formed in the middle of the clamping plate, the reinforcing steel bar inserting grooves extend in a linear mode, the extending direction of the reinforcing steel bar inserting grooves is perpendicular to the axis of the clamping plate, and splicing seams are formed in the axis position of the clamping plate in a penetrating mode; the splicing seam divides the steel bar inserting groove and the vibrating hole into two parts, the clamping plate is cut into a left clamping plate and a right clamping plate which are symmetrical to each other, a connecting mechanism is arranged between the left clamping plate and the right clamping plate, and the left clamping plate and the right clamping plate are clamped and fixed through the connecting mechanism. The clamping tool is simple in structure, ingenious in design, convenient to assemble and disassemble and high in turnover rate, an integral clamping tool is improved to be in a splicing mode, then an upward lifting disassembling mode is improved to be a disassembling mode of horizontally moving and drawing towards the two sides, the problem that the clamping tool is blocked by reinforcing steel bars and is prone to being blocked is solved, the disassembling difficulty of the clamping tool is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a positioning jig for a steel bar at a transfer layer of a prefabricated building and a construction method thereof. Background technique [0002] During the construction process of the prefabricated shear wall structure, especially the conversion position between the cast-in-place floor and the prefabricated floor, it is necessary to pre-embed the inserts in the cast-in-place concrete for the grouting sleeve connection of the prefabricated shear wall components. Since the construction of the cast-in-place floor reinforcement is to bind the reinforcement first, and then pour the concrete, because the position of the insertion bar needs to be accurately positioned, so that the sleeve of the prefabricated floor can insert the insertion bar accurately. The existing steel bar positioning fixtures are all integral structures. Although such fixtures can init...

AI Technical Summary

Problems solved by technology

The existing steel bar positioning fixtures are all integral structures. Although such fixtures can initially ensure accurate positioning of the steel bar roots, they have the following disadvantages: it is very inconvenient to remove the fixtures, because once the upper part of the steel bars is touched and shifted, the fixtures will be lifted up. During the dismantling process, it will be blocked by the steel bar and cause jamming, resulting in difficulty in dismantling; the middle slot of the clamp is a long hole, and the U-shaped steel bar is easy to move laterally along the slot during subsequent construction, resulting in inaccurate final position
