Fastening type cylindrical timber formwork concrete casting construction method

Abstract

The invention belongs to the technical field of construction and particularly relates to a fastening type cylindrical timber formwork concrete casting construction method. The method comprises the following steps: (1) binding a pillar main bar; (2) positioning; (3) manufacturing a template; (4) mounting the template; (5) cutting the template at the crossed part of a beam column; (6) reinforcing the template; (7) integrally fixing a template system; (8) performing concrete casting; (9) stripping of the formwork. According to the invention, the timber formwork is light in weight; as birch and poplar are adopted as the raw materials, the strength is high and the toughness is good; a template of 3 m in height is generally 40-45 Kg, so that two persons can work together to complete the mounting; compared with the traditional steel form construction, 70% construction period is shortened; as the shaped cylindrical template is adopted and the connector of the template adopts a unique convex through groove design, the abutted seams are closely combined, paste void and leakage are prevented, and concrete demoulding is quick and attractive; the difficult problem that the steel form can not be cut at will is solved, arbitrary cutting can be realized according to actual size, and accordingly, the construction difficulty is lowered for the construction side.

Description

technical field [0001] The invention relates to a buckling-type wooden formwork column concrete pouring construction method, which belongs to the technical field of construction. Background technique [0002] With the development of high-rise buildings, various special-shaped buildings are gradually increasing, and columns are used more and more in architectural design. The formwork used in column construction mainly includes cylindrical steel formwork and PVC plastic formwork. The installation of steel formwork is heavy and requires a larger Lifting equipment is time-consuming and labor-intensive. Although the PVC formwork is light in weight, it is easy to cause arc errors due to formwork thread defects, and the pass rate of the punched cylinders is low, especially the interface parts, which generally require secondary repairs. In order to solve the above problems, our company adopts buckle-type cylindrical wooden formwork during column construction. Using this formwork, th...
