Embodiment Construction
[0024] Specific embodiments of the present invention will be described in detail below.
[0025] In the cylindrical structure at the end of the shear wall, such as figure 1 As shown, the diameter of the cylinder is 500mm, and the bellows with the same diameter is used as the formwork. The inner diameter of the bellows formwork is 500mm. The inner wall of the bellows formwork is smooth, high in strength, light in weight, and the outer wall presents a ring-shaped corrugated structure, which increases the ring stiffness of the pipe and is not easily deformed. Before the corrugated pipe is installed, an electric drill is used to drill holes on the pipe wall to reserve the position of the horizontal ribs of the shear wall (thickness 200mm). molding quality. The square wood is stuffed into the back of the bellows and fixed with iron hoops. The whole formwork is connected with the scaffolding by steel pipes to meet the construction stability requirements. After the cylindrical conc...

Disclosed is a construction method for shear wall side cylinder. Corrugated pipes of the same diameter are used as form-works for structuring shear wall side cylinders. The inside walls of the corrugated pipe are smooth, lightweight and of high strength. The outside walls of the corrugated pipe display annular corrugated structures, enhancing the rigidity of the corrugated pipe tubing. The corrugated pipe is therefore not easily deformed. Drill holes with an electric drill into the corrugated pipe walls beforehand to form positions for the installation of shear wall horizontal tendons prior to the installation of the corrugated pipes. Assemble the corrugated pipe form-works and then insert the shear wall horizontal tendons before further reinforce the form-works. The aforementioned process can reduce the piecing process, as well improve concrete molding quality after disassembling the form-works. Whereafter, squeeze lumps of wood into the back of the corrugated pipes and fix the lumps of wood and corrugated pipes in iron hoops. The hoop for the cylinder is a combination of 5mm-thick, 50mm wide zinced iron hoops and screw. The entire construction of form-works adopts the mean of connecting steel pipes and full scaffolds, which meet the requirement of construction stability. When it is the appropriate time to disassemble the form-works after finishing pouring concrete into the cylinders, disassemble the corrugated pipes and then conduct construction for shear wall side cylinder by means of construction technics of common wooden form-work.
Description
technical field [0001] The invention belongs to the field of construction, in particular to a construction method for a column at the end of a shear wall of a heterogeneous concrete structure. Background technique [0002] With the development of the country's economy and culture, the existing types of engineering building structures can no longer meet the requirements. More and more special-shaped concrete structures are being designed and applied in construction, especially major monumental buildings, in which columns and shear walls are connected. Combinations are becoming more and more common. The traditional cast-in-place concrete cylindrical formwork support adopts conventional materials (wooden shaped round formwork) and construction technology cannot meet the requirements of project quality, construction period and cost. Contents of the invention [0003] In order to solve the problem that the current traditional cast-in-place concrete cylindrical formwork support...
