specific Embodiment

[0037] The template erection of the expansion joint shear wall of a luxury house (Building 8-10) in a local project, after adopting this method, it is relatively economical in terms of construction period, material investment, and capital investment, which conforms to the principle of cost control and meets the requirements of the construction period. To ensure the appearance quality of concrete components; No. 8 building has a basement floor, 32 floors above ground, a floor height of 3000mm, and a plane length of expansion joints of 7 meters. The economic comparison analysis before and after construction is carried out. The economic benefit analysis after use is specifically shown in Table 1 as follows:

[0038] Table 1

[0039]

[0040] Specific implementation steps:

[0041] 1. According to the plane size of the shear wall, 40*40 square steel is welded and assembled according to the vertical and horizontal spacing of 450*450 as the skeleton;

[0042] 2. According to the...

Abstract

The invention discloses an expansion joint position shear wall side formwork reinforcing device and a construction method, and relates to the technical field of construction. A pair of side formworksare fixed to an expansion joint close to a cast shear wall, a main and auxiliary keel and a first clamping plate are fixed to form an overall formwork, round steel lifting hooks are welded to the upper end of the overall formwork, and movable nuts are screwed in one direction to fix the pair of side formworks after bolts sequentially penetrate through the movable nuts, a wooden edge, a second clamping plate, the pair of side formworks, the overall formwork and fixed nuts. The construction method includes the steps of firstly, longitudinally and transversely arranging the main and auxiliary keel through a plurality of square steel pipes, and fixing the main and auxiliary keel and the first clamping plate to form the overall formwork; secondly, welding the nuts to the main and auxiliary keelthrough positioning of longitudinal and transverse distances of the oppositely penetrating bolt; thirdly, welding the two round steel lifting hooks to the upper end of the overall formwork. Formworkexpansion and formwork explosion are well avoided, the appearance and quality problems caused by size deformation are avoided, materials can be recycled multiple times after one-time input, and the concrete forming appearance is good.

Description

Technical field: [0001] The invention relates to a reinforcement device and a construction method for a shear wall side form at an expansion joint position, and belongs to the technical field of building construction. Background technique: [0002] The operation space at the location of the expansion joint is narrow. After the construction of the shear wall on one side is completed, when the formwork of the other side of the shear wall is installed, there are problems such as fixing and removing the formwork. Usually, extruded boards are used for isolation or conventional formwork for wood reinforcement. , the appearance quality of concrete components is difficult to ensure, the formwork cannot be removed, and the shear wall cannot normally play the role of expansion gap due to the connection of shear walls. Invention content: [0003] The invention provides a reinforcement device and a construction method for a shear wall side form at an expansion joint position, which so...
