Prefabricated assembly type hybrid fan tower formwork supporting method and device

Abstract

The invention discloses a prefabricated assembly type hybrid fan tower formwork supporting method and a prefabricated assembly type hybrid fan tower formwork supporting device. The device comprises abase, a bottom plate, a bottom formwork and anchor cable positioning pipes, inner formwork positioning holes which are uniformly distributed are formed in the inner edge of the top surface of the bottom formwork; an inner formwork and an outer formwork are arranged at the top end of the bottom formwork; an inner formwork frame is arranged at an inner formwork positioning hole; an outer formwork frame is arranged at an outer formwork positioning hole; a central column is further arranged on the inner side of the inner formwork; the inner wall of the central column is movably connected with a jacking column; a supporting rod is movably connected with a rotary connecting rod through a thread; one end of the rotary connecting rod is connected with the inner wall of the inner formwork through asupporting plate, transverse reinforcing ribs and longitudinal reinforcing ribs are arranged on the side wall of the inner formwork, a connecting plate and a rib plate are further arranged on the side wall of the inner formwork, an inner support and an outer support are connected with an inner baffle and an outer baffle through bolts, and the inner baffle and the outer baffle are connected with avertical support and an inclined support. The whole equipment transportation and installation process is simple, meanwhile, the installed equipment is high in stability and strength, and the engineering construction time is greatly shortened.

Description

technical field [0001] The invention relates to a prefabricated assembly tower formwork, in particular to a method and device for supporting a prefabricated assembly tower formwork of a mixed fan. Background technique [0002] The fan tower is composed of several sections of concrete towers and several sections of steel towers. First, the concrete towers prefabricated in the factory are transported to the fan stand, and all the concrete towers and bottom steel towers are installed section by section. A number of anchor cables pass through the prestressed anchor cable channels reserved on the concrete tower and the channels on the reverse balance flange of the steel tower at the bottom section, and are stretched in stages to form a whole. Therefore, the concrete tower, The horizontality of the lower bottom, the verticality of the tower, the verticality of the prestressed anchor cable channel, and the accuracy of the spacing are the key points, which are directly related to th...

Problems solved by technology

[0002] The fan tower is composed of several sections of concrete towers and several sections of steel towers. First, the concrete towers prefabricated in the factory are transported to the fan stand, and all the concrete towers and bottom steel towers are installed section by section. A number of anchor cables pass through the prestressed anchor cable channels reserved on the concrete tower and the channels on the reverse balance flange of the steel tower at the bottom section, and are stretched in stages to form a whole. Therefore, the concrete tower, The horizontality of the lower bottom, the verticality of the tower, the verticality of the prestressed anchor cable channel, and the accuracy of the spacing are the key points, which are directly related to the appearance quality of the tower and the installation accuracy of the concrete tower and the steel tower at the bottom. Some templates are generally large in size and inconvenient to transport and install

[0003] During construction, elastic rubber pull-out rods are used to pre-embed in the concrete structure, and the rubber pull-out rods are pulled out 3 hours after the initial setting of the concrete, forming holes through the concrete structure up and down, which are inserted as prestressed steel strand bundles The hole, because the rubber rod is very soft, the rubber rod needs to be bound and fixed with a steel wire during the actual operation.

Secondly, the use of conventional formwork operations not only affects the appearance, but the stability and strength of the equipment after installation are not high, and it is prone to common quality problems such as mold expansion and slurry leakage, which affects the construction time of the project
