Problems solved by technology

[0002] The tower column of the reinforced concrete leaning tower of the cable-stayed bridge generally adopts a rectangular hollow section, and the shape of the tower column adopts an equal cross-section arrangement. Due to the slope and high height, the construction of steel bars and formwork is difficult, so the ordinary formwork reinforcement scheme is difficult in this case. To achieve the purpose of construction

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] like figure 1 , 2 As shown, according to the inclination of the main tower body of the construction is 30 degrees or other degrees, the hydraulic climbing formwork system designed for this project mainly includes: formwork, load-bearing system, upper and lower climbing frames, embedded parts, and guide rails , hydraulic system, etc.

[0032] like Figure 3-6 As shown, the template part is composed of panels, horizontal steel back corrugated 7, connecting claws 8, hoisting components 9, floor nails 10, fiberboard nails 11 and other parts connected. The panel adopts 21mm Visa board 12, the reinforcing rib adopts H200 wooden I-beam 13, and the horizontal steel back corrugation adopts double 14a channel steel 14.

[0033] The wooden formwork is easy to load, disassemble and assemble, and can be assembled into formworks of various sizes within a certain range and degr...

Abstract

The invention discloses a hydraulic climbing formwork construction method for a leaning tower of a cable-stayed bridge. The method comprises the following steps: measuring and positioning the leaning tower and embedding an embedded part; erecting a formwork and pouring a first section of concrete, and mounting an anchoring system, a bearing bolt (1) and a climbing frame (3); mounting a bearing frame and a bearing platform on the anchoring system; mounting a template moving frame and an upper platform system, using the upper platform system for erecting the formwork, embedding the embedded part and pouring a second section of concrete of a tower column; mounting a lower platform and de-molding by moving the upper platform system; mounting the anchoring system in a third stage and mounting a climbing guide rail (5) and a guide rail supporting leg (6); operating a hydraulic system, lifting the whole frame to the third stage of the tower column, and mounting a lower-layer platform; assembling the mould by moving the upper platform system, embedding the embedded part and pouring a fourth section of concrete of the tower column; and operating the hydraulic system, lifting the whole frame to the fourth stage of the tower column, and entering into a circulating construction stage. According to the method provided by the invention, the mounting of the template is quickly and efficiently finished under the condition of the leaning tower column and the work load of mounting the template and the bracket is saved.

Description

technical field [0001] The invention mainly relates to a construction method applied to the inclined tower of a cable-stayed bridge, in particular to a hydraulic climbing formwork construction method applied to the inclined tower of a cable-stayed bridge. Background technique [0002] The tower column of the reinforced concrete leaning tower of the cable-stayed bridge generally adopts a rectangular hollow section, and the shape of the tower column adopts an equal-section arrangement. Due to the slope and high height, the construction of steel bars and formwork is difficult, so the ordinary formwork reinforcement scheme is difficult in this case. To achieve the purpose of construction. Contents of the invention [0003] The technical problem to be solved by the present invention is how to quickly and effectively complete the installation of formwork and save the engineering quantity of formwork and brackets when the tower column is inclined. [0004] In order to achieve th...
