Integral assembly of large formwork narrow space wall and construction method

Abstract

The invention relates to an integrally assembled large formwork narrow space wall and a construction method. An expansion control body is arranged in the joint strip of the wall side formwork; a joint is provided between the wall side formwork and the joint between the wall body formwork and the wall end formwork Groove plate, guide connecting plate and rotating joint bolts; a horizontal support composed of supporting outer tube and supporting inner tube is set between the wall side formwork and the external wall; after the hoisting connection falcon is connected with the hoisting connection groove, through The formwork lifting rod is used for hoisting construction of the side formwork of the wall; the pull screw is composed of a fastening outer tube, a retractable inner tube, an outer tube fastening bolt and a protective sleeve, and is connected with the bolt reinforcement; through the position control sling The vertical height of the maintenance bearing plate is controlled, and a sliding water collection tank is set at the lower part of the maintenance bearing plate, and elastic sealing ribs are set between the support plate at the bottom of the plate and the sealing body on the side of the tank. The invention can improve the supporting quality of the formwork of the wall, reduce the construction difficulty of formwork supporting and concrete maintenance, improve the mechanical performance of the construction structure and protect the construction environment.

Description

technical field [0001] The invention belongs to the field of construction engineering, and particularly relates to an integrally assembled large formwork narrow space wall that can improve the quality of wall formwork support, reduce the difficulty of formwork support and concrete maintenance construction, improve the mechanical performance of the construction structure, and protect the construction environment. The construction method is suitable for the construction of concrete walls in narrow spaces. Background technique [0002] With the rapid development of urban construction, the number of tall construction projects is increasing, and the density between buildings is also increasing. There are more and more construction projects involving limited construction space. In engineering projects with limited construction space, the difficulty of construction is often much greater than that of conventional engineering projects, mainly reflected in: difficulty in dismantling f...

AI Technical Summary

Problems solved by technology

Although this construction method can solve the overall support problem of the formwork, it is difficult to solve the technical problems of quick connection and positioning of the formwork, low-damage connection of the tension screw, and efficient concrete maintenance.
