The steel tower section is composed of several steel tower sections (the structure of the steel tower section is equivalent to a large-sized square pipe), which can be called T0 section, T1 section, T2 section... TN from bottom to top Segment, due to the different materials of the concrete section and the steel tower section, and the heavy weight of the steel tower section, it is difficult to locate the T0 section at the bottom of the steel tower section during the connection process with the concrete section, and it is prone to deviation and difficult to correct after deviation

Embodiment Construction
[0014] Combine below Figure 1 to Figure 8 , the present invention is described in further detail.
[0015] refer to Figure 1-Figure 5 , a cable-stayed bridge steel tower combination section installation aids, including a support unit 10 supporting the steel tower T0 section A and a positioning unit 20 driving the displacement of the T0 section A in the horizontal plane, the support unit 10 and the concrete section B and The upper surface of the junction of the T0 segment A constitutes a sliding fit, and the height of the support unit 10 and the positioning unit 20 is adjustable. Due to the heavy weight of the T0 section A, it is difficult to adjust the horizontal position of the T0 section A when the T0 section A is placed directly on the concrete section B. Here, the T0 section A is placed on the slidable support unit 10 In addition, the horizontal position of the T0 segment A is accurately adjusted by the positioning unit 20 to ensure that the horizontal position of the ...

The invention relates to the field of civil engineering, in particular to an assistive device for installing a cable-stayed bridge steel tower combination section. The assistive device comprises supporting units and a positioning unit, wherein the supporting units are used for supporting a steel tower T0 section, and the positioning unit drives the T0 section to displace in the horizontal plane. The supporting units are in sliding fit with the upper surface of the position where a concrete section is combined with the T0 section, and the supporting units and the positioning unit are adjustable in height. Due to the fact that the T0 section is heavy, the horizontal position can not be easily adjusted when the T0 section is directly placed on the concrete section, the T0 section is supported with the supporting units, due to the fact that the supporting units and the upper surface of the concrete section are slideable, the horizontal position of the T0 section can be easily adjusted through the positioning unit, the T0 section can be adjusted in the vertical direction by adjusting the heights of the supporting units and the height of the positioning unit, and therefore the requirement for accurately positioning the T0 section is met.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to an auxiliary device for installing a steel tower joint section of a cable-stayed bridge. Background technique [0002] The main tower of the cable-stayed bridge is composed of a concrete section and a steel tower section. During construction, the concrete section is poured first, and then the steel tower section is installed on the concrete section. The steel tower section is composed of several steel tower sections (the structure of the steel tower section is equivalent to a large-sized square pipe), which can be called T0 section, T1 section, T2 section... TN from bottom to top Segment, due to the different materials of the concrete section and the steel tower section, and the heavy weight of the steel tower section, it is difficult to locate the T0 section at the bottom of the steel tower section during the connection process with the concrete section, and it is prone to devia...
