Embodiment Construction

[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like figure 1 and 2 As shown, the positioning device of the cable-stayed saddle includes a base 1 made of angle steel, and the two ends of the base are respectively hinged with a support rod 2 and a telescopic support 3, and the other end of the support rod is hinged with the telescopic support, and can be adjusted by The length of the telescopic support can adjust the inclination of the support rod, and then adjust the installation angle of the cable saddle.

[0024] The upper end of the support rod 2 is connected with a load-bearing plate 4 for placing a cable saddle 6, and a pair of limit plates 5 are arranged on the load-bearing plate.

[0025] The concrete implementation process that the present invention adopts positioning device to carry out positioning construction to cable saddle is as follows:

[0026] 1. Elevation position...

Abstract

The invention provides a stay cable saddle positioning device. The device comprises a base, supporting rods with one ends hinged to the base respectively, and a telescopic support, wherein the supporting rods are hinged to the other end of the telescopic support, and a bearing plate used for accommodating a cable saddle is connected to the upper end of each supporting rod. A stay cable saddle positioning method adopting the positioning device comprises the steps of 1, arranging an elevation point on the outer side of a stiff skeleton at the top end of a well poured tower column, and determining the positioning elevation of the cable saddle according to the elevation point; 2, adjusting the length of the telescopic support to enable the angle of each supporting rod to be consistent with the angle of a sub-steel-pipe; 3, giving off a center cross line of a main tower by means of a total station after tower column construction is finished, determining the direction of the cable saddle by means of a plumb, and installing the cable saddle; 4, re-checking the coordinates of the positioning key points of the cable saddle by means of the total station, adjusting the position of the cable saddle, fixing the cable saddle, and dismounting the positioning device. By the adoption of the device and method, cable saddle positioning precision is ensured, project quality is guaranteed, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridge construction, in particular to a positioning device and a positioning method for a cable-stayed saddle. Background technique [0002] The installation accuracy of the cable saddle and its geometric line shape will be an important condition to ensure that the concrete of the tower column and the cable saddle are jointly stressed and prevent cracks in the concrete. In the fan-shaped cable-stayed cables, the cable guides of the main tower are all arranged in the upper column section of the main tower, and their distribution is relatively dense, the inclination angle changes greatly, the installation and construction space of the cable saddle is small, and the interference is large. Contents of the invention [0003] In order to solve the shortcomings of difficult construction and low efficiency in the prior art, the invention provides a positioning device for a cable-stayed saddle to en...
