Concrete Pouring Construction Method of Cylinder of Fastening Wooden Formwork

Abstract

The invention belongs to the technical field of construction, and in particular relates to a construction method for fastening wooden formwork cylindrical concrete, which comprises the following steps: 1) Binding the main reinforcement of the column; 2) Positioning; 3) Formwork production; 4) Formwork installation; 6) formwork reinforcement; 7) overall fixation of the formwork system; 8) concrete pouring; 9) formwork removal. The wooden formwork of the present invention is light in weight, adopts birch poplar as raw material, has high strength and good toughness, and the general weight of a formwork with a height of 3m is 40-45Kg, and the installation operation can be completed by two people's cooperation. Compared with the traditional steel formwork construction, it is shorter 70% of the construction period; the shaped cylindrical formwork is adopted, and the unique convex groove design is adopted at the formwork interface, so that the joints are tightly combined to prevent grout running and leakage, and the concrete demoulding is fast and beautiful; it solves the problem that the steel formwork cannot be arbitrarily The difficult problem of cutting can be cut arbitrarily according to the actual size, which reduces the difficulty of construction for the construction party.

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...
