Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] A construction method for expansion joint shaped formwork, the steps are as follows:

[0026] Step 1. Design the expansion joint. The design is calculated according to the measured thickness. The width of the expansion joint is ≥ 2 thicknesses of multilayer boards + 2 corrugated heights + 2 steel pipe diameters + 2 nut thicknesses;

[0027] Step 2. Formwork processing. Use multi-layer boards with a thickness of 12-18mm to make the formwork to ensure that the drilling positions of the formwork on both sides of the expansion joint are strictly aligned. The distance between the fastening screws is the same as that of the conventional shear wall. In addition to the screw, it is necessary to add a reverse fixed keel shaping screw to ensure that the primary and secondary keels are integrated with the wooden formwork;

[0028] Step 3. Welding of fasteners. Before welding o...

Abstract

The invention discloses a construction method of an expansion joint shape setting formwork. The construction method comprises the steps that an expansion joint template is designed, the shape setting formwork is processed, fastener welding is performed, columns and wall board steel bars are bound, indoor columns and wall board templates are installed, screw penetration is performed, screw rod penetration is performed from insides of rooms after preparation is completed, the axis position and perpendicularity are calibrated, opposite-pull screw rods are tightened, a lower opening of the formwork and concrete floors are caulked with cement mortar, concrete is cast after acceptance inspection is passed, and the formwork and the opposite-pull screw rods are dismounted. The construction method has no special requirement for the formwork and other accessory materials, the demand can be met only by selecting conventional qualified materials, labors, machinery and materials are saved, a construction period is greatly shortened, and the input shape setting formwork can be used cyclically. Compared with a traditional method, material waste is reduced, the working efficiency of construction workers in operation and usage is improved by means of the construction method, a good role is played on structure forming of the expansion joint position, and on-site actual operation support is provided for the forming quality of the position of a similar ultra-long building.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction method of expansion joint shaped formwork which improves the turnover times of formwork and saves resources. Background technique [0002] At present, many wall formworks of domestic residential engineering shear wall structures use wooden formwork for on-site loose construction. This kind of construction method is convenient and fast, and can effectively reduce the dependence of engineering construction on tower cranes. It is suitable for the construction of higher-rise shear wall structures, especially for the construction of high-rise shear wall structures in coastal areas and other areas with strong winds. In the construction of shear wall structures with expansion joints, such construction methods are often abandoned, or foam boards are used to fill the expansion joints. The latter not only wastes materials and increases construction costs, but also the ...
