Tube structure roof panel construction method and hanger formwork system

Abstract

The invention discloses a tube structure roof panel construction method. The method comprises the steps of 1, building a tube structure with a slip-form construction method, and arranging an embedded ring at the top end of a tube wall; 2, splitting a slip form inner frame and a slip form outer frame and lowering the slip form inner frame to be below the elevation of a roof panel after tube wall slip-form construction; 4, fixedly connecting the slip form inner frame with the embedded ring with a steel wire rope, and then making the slip form inner frame fixed relative to the inner wall of a tube body; 5, laying planks and steel channels on the slip form inner frame, and conducting support frame erection and roof construction. The invention further discloses a construction system. According to the roof panel construction hanger formwork system, the slip form inner frame is transformed into a hanger formwork to serve as a support platform of a roof panel support frame, so that roof panel construction is conducted; a pull-up reinforcing mode is adopted for the hanger formwork, the hanger formwork and the embedded ring at the top end of the tube wall are connected through the steel wire rope on the upper portion, the hanger formwork abuts against the tube wall through a U-shaped support, swing of a frame body is effectively prevented, the using range and using time of the hanger formwork system are widened and prolonged, construction difficulty is reduced, construction period is shortened, danger coefficient is reduced, and construction cost is saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a cylindrical structure roof panel and a hanging formwork system. Background technique [0002] The cylinder structure is widely used in the construction industry due to its good rigidity and strong earthquake resistance, especially chimneys, coal bunkers, and granaries in industrial buildings. The structure of the cylinder structure is simple, and most of the cylinder walls are constructed in the form of sliding form. A roof panel is installed at the top of the cylinder, and the traditional construction method of the roof panel is to build a full house support frame. Since the inner floor of the cylinder structure is relatively high, the construction of the roof panel in the cylinder structure is difficult, the workload is heavy, and the risk factor is high. Contents of the invention [0003] The object of the present invention is to prov...

AI Technical Summary

Problems solved by technology

The roof panel is installed at the top of the cylinder, and the traditional construction method of the roof panel is to build a full hall support frame. Because the inner floor of the cylinder structure is relatively high, the roof panel of the cylinder structure has the characteristics of difficult construction, heavy workload, and high risk factor.
