Formwork reinforcement system with overall pouring construction of L-type short-leg shear wall

Abstract

The invention relates to a formwork reinforcement system with overall pouring construction of an L-type short-leg shear wall. The system comprises an L-type short-leg wall body 1 and an L-type short-leg wall top board 2; outer side wood plywood formworks 3 and inner side wood plywood formworks 4 are arranged on the outer sides and the inner sides of the L-type short-leg wall body 1 and the L-type short-leg wall top board 2, and end portion formworks 7 are arranged at the end portions of the L-type short-leg wall body 1 and the L-type short-leg wall top board 2; outer side back edge wood lumps 9 are arranged between the outer side wood plywood formworks 3 and a double-steel-pipe outer formwork 11; inner side back edge wood lumps 10 are arranged between the inner side wood plywood formworks 4 and a double-steel-pipe inner formwork 12; end portion wood lump back edges 24 are arranged on the outer sides of the end portion formworks 7 and located between end portion double-steel-pipe steel frameworks 21 and the end portion formworks 7; and the inner side back edge wood lumps 10 and the outer side back edge wood lumps 9 are bound to the double-steel-pipe inner formwork 12 and the double-steel-pipe outer formwork 11 through iron wires 20.

Description

technical field [0001] The invention relates to a formwork reinforcement system for the integral pouring construction of an L-shaped short-leg shear wall, in particular to a formwork reinforcement system suitable for the integral pouring construction of a wall column and a top plate of a short-leg shear wall in a multi-storey residence. Background technique [0002] The L-shaped short limb shear wall uses the position of the partition wall to arrange the vertical components. The structure of the shear wall limb is complex, with long and short, many corners, and many special-shaped columns. The existing L-shaped short-leg shear wall concrete construction method is to use steel pipe scaffolding, cross fasteners, and steel pipe back corrugated to form a support system to reinforce large and small steel formwork. The reinforcement method is "construct the wall first, and then construct the roof" separately. Do. Using this method in the construction of L-shaped short-leg shear w...

AI Technical Summary

Problems solved by technology

Using this method in the construction of L-shaped short-leg shear walls has the disadvantages of slow speed, poor overall stability of the formwork, easy work, fragmented formwork, high dependence on vertical transportation, low turnover efficiency, difficulty in formwork reinforcement, and inability to meet multi-size components Shortcomings such as advanced formwork assembly process, resulting in poor quality of concrete structure from time to time

If the traditional steel formwork is used for the concrete pouring construction of the L-shaped short-leg shear wall, the cost of the formwork project accounts for about 30% of the total cost of the reinforced concrete project of the short-leg shear wall structure, and about 40% of the total labor, which is greatly increased. project cost
