Formworkfor elevator well of high rising building and construction method thereof

Abstract

The invention relates to a formwork for construction and a construction method thereof, in particular to high-rise building elevator barrel formwork and a construction method thereof. The barrel formwork comprises an angle formwork and a large formwork; the large formwork is supported by an upper steel brace and a lower steel brace, the upper steel brace and the lower steel brace respectively meet an upper control block that controls the expansion of the upper steel brace and a lower control block that controls the expansion of the lower steel brace; the control block is provided with a track and a hole which goes through by the steel brace is arranged between the track and the side wall; the steel braces in the same vertical plane are in rigid connection through a fixed column; a pulley is arranged between the steel brace and the track and the upper part of the track of the upper control block inclines outward; the lower part of the lower control block inclines outside; threaded holes are positioned between the upper control block and the lower control block, the threaded hole of the upper control block is a right threaded hole, and the threaded hole of the lower control block is a left threaded hole, the upper control block and the lower control block are connected by a screw through the threaded holes and the upper part of the screw is in rigid connection with a wrench. The barrel formwork has easy production and operation, and reduces the cost and working hour.

Description

technical field [0001] The invention relates to a formwork for building and a construction method thereof, and more specifically relates to a novel elevator shaft formwork for a high-rise building and a construction method thereof. Background technique [0002] The existing commonly used barrel mold support systems are roughly divided into two categories: triangular chain barrel mold and eight-hinge barrel mold. The production of these two barrel mold support systems is relatively complicated, and hinges are required for connection; the operation requires twisting multiple wrenches at the same time, and it is not easy to adjust to a vertical angle, requiring more man-hours. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the existing barrel mold, further reduce the cost and improve the benefit, and provide an elevator shaft mold that is easier to manufacture, lowers the cost, is easier to operate, and re...
