Hoisting device and hoisting method of automatic mold lowering system by reverse method

Abstract

The invention provides an automatic formwork lowering system hoisting device and method for top-down construction and belongs to the field of building construction. By the adoption of the automatic formwork lowering system hoisting device and method for top-down construction, the problems that an existing formwork system hoisting device is not universal, and a formwork system needs to be dismounted and mounted repeatedly are solved. The automatic formwork lowering system hoisting device for top-down construction comprises a stress boom assembly, a force bearing support and a gasket. The stress boom assembly comprises a plurality of stress booms and a plurality of thread connectors. The force bearing support comprises two sub-nuts, a nut sleeve and a plurality of set screws. The length of the stress boom assembly can be adjusted by adjusting the number of the applied stress booms and the number of the applied thread connectors according to actual conditions, so that different engineering requirements are met. The invention further discloses the automatic formwork lowering system hoisting method for top-down construction. By the adoption of the automatic formwork lowering system hoisting method for top-down construction, the situation that the formwork system needs to be dismounted and mounted repeatedly during top-down construction can be avoided. In a word, by the adoption of the automatic formwork lowering system hoisting device and method for top-down construction, the construction cost of projects can be effectively reduced, and the labor intensity of operators is relieved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a hoisting device and a hoisting method for an automatic formwork lowering system of the reverse method. Background technique [0002] With the rapid development of the city, in the field of urban construction, reverse construction has attracted more and more attention due to its advantages of short construction period, high safety, and small impact on surrounding buildings (structures), and has been applied to In more and more engineering projects. [0003] The traditional reverse method is to continue to dig a certain space downward after digging to the design elevation, and use this part of the over-excavated space to build a formwork system and formwork support system for the reinforced concrete beam (floor) poured on site, so it is necessary to pour a temporary At the same time, because the reinforced concrete beams (floors) poured on site need time maintenance, earthwo...
