Hollow shear wall vertical reserved steel bar fixing device and construction method thereof

Abstract

The invention relates to a hollow shear wall vertical reserved steel bar fixing device which comprises two parallel telescopic rods and a plurality of sliding assemblies sliding on the two telescopic rods, scale holes are evenly formed in the upper sides of the telescopic rods, and each sliding assembly comprises two cylinders, a connecting plate, a fastener and a fixing hole. The two cylinders are arranged at the two ends of the connecting plate and are parallel to the connecting plate, the two cylinders slide on the parallel telescopic rods respectively, the fixing holes are formed in the connecting plate and are matched with reserved steel bars, and the fasteners are arranged on the outer sides of the two cylinders. The construction method comprises the steps of determining a design model; modeling and simulating an experiment; field actual installation; and field acceptance. According to the fixing device, the position of the sliding assembly on the telescopic rod can be conveniently and accurately adjusted, the position of the embedded joint bar can be rapidly positioned, and the problems that the vertical steel bars of the latticed hollow shear wall are multiple in deviation and poor in effect can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a vertical reserved steel reinforcement fixing device for a hollow shear wall and a construction method thereof. Background technique [0002] Shear wall, also known as wind-resistant wall or seismic wall, structural wall. A wall in a house or structure that mainly bears horizontal and vertical loads caused by wind loads or earthquakes. Prevent structural shear damage. It is divided into plane shear wall and cylindrical shear wall. Plane shear walls are used in reinforced concrete frame structures, rising slab structures, and beamless floor systems. In order to increase the stiffness, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or prefabricated in some parts. The cast-in-place shear wall and the surrounding beams and columns are cast at the same time, and the integrity is good. The cylindrical shear wa...

AI Technical Summary

Problems solved by technology

[0004] The size of the vertical reserved steel bars in the traditional shear wall is large, while the size of the reserved vertical steel bars in the prefabricated grid-shaped hollow shear wall is small, the positioning effect is low, and the amount of steel bars is seriously wasted.

The on-site construction workers who carry out the next step of concrete pouring process are likely to damage the positioning of the reserved vertical reinforcement of the prefabricated grid-shaped hollow shear wall, which makes the reserved vertical reinforcement of the prefabricated grid-shaped hollow shear wall deviate, the structural system is damaged, and the structural strength reduce
