A formwork reinforcement method for the external corner of the shear wall and the position of the door opening

Abstract

The invention discloses a reinforcing structure for a shearing wall template and a reinforcing construction method thereof. The reinforcing structure comprises main template keels, auxiliary template keels, through-wall opposite-pull screws and horizontal-E-shaped clamps, wherein the main template keels distributed along the length direction of a wall body also comprise opposite-pull connectors; the matched short opposite-pull screws and the horizontal-E-shaped clamps are adopted for connecting and reinforcing the adjacent main template keels distributed along the length direction of the wall body at the positions of two opposite-pull connectors which are arranged oppositely; the opposite-pull connectors of the main template keels along the length direction of the wall body are directly connected with the main template keels of the intersected wall body at the other side by the short opposite-pull screws and the horizontal-E-shaped clamps. The reinforcing structure disclosed by the invention has the advantage that the difficulty of reinforcement of large-section shearing wall bodies, wall bodies built at the external corners and door openings of the shearing walls are solved.

Description

technical field [0001] The invention relates to a wall formwork reinforcement technology for a shear wall structure or a frame shear wall structure, in particular to a reinforcement structure of an ultra-long and ultra-thick cross-section wall, an external corner of the wall, and a shear wall formwork at the position of a door opening and its Reinforcement construction method. Background technique [0002] Shear walls are also called wind-resistant walls, seismic walls or structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. Also known as seismic walls, generally made of reinforced concrete. The building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct...

AI Technical Summary

Problems solved by technology

The technical requirements of this process are high, and the reinforcement process is cumbersome, especially the reinforcement of the openings and corners of the shear wall is a difficult problem for the construction workers in the entire construction industry.

[0003] At present, the reinforcement of shear wall formwork is mostly completed by double-channel steel pipes, wall-penetrating screws, mountain clips, step-by-step tightness, steel pipe fasteners, iron wires and other components. Fasteners and high-strength screws are used at the corners of shear wall formwork reinforcement. The combination of vertical and horizontal knots, the site is messy, and most of the openings and columns are reinforced by step-by-step and iron wires, and the auxiliary jacking and full frame are used to complete the formwork reinforcement at the corners and openings, which is very cumbersome; the shear wall structure Or the wooden formwork reinforcement of the wall of the frame shear wall structure, the door opening is generally reinforced by the method of facing the top. This reinforcement method needs to be poured symmetrically on both sides of the opening to make the formwork on both sides of the opposite roof evenly stressed, but it cannot be done on site. When it is poured symmetrically, the dimension of the door opening is often inconsistent with the design, which affects the quality of the structural molding

[0004] The above-mentioned existing reinforcement structures and methods not only have poor reinforcement effect, cumbersome operation and messy site, but the most important thing is that the reinforcement of large cross-section walls cannot be completed. , steel pipe fasteners, iron wires and other components are only suitable for walls with small sections in the length direction. The external corners of large-section shear walls and the head of the end of the wall cannot be worn right along the length direction of the wall. Pulling the screw, the reinforcement of these positions has always been a major problem in the reinforcement of building formwork. The reinforcement effect is not ideal. During the pouring process, mold expansion or even mold explosion often occurs.
