Embodiment Construction
[0009] 1. Set corbels and sliders on the inner side of the steel beam
[0010] Creatively set corbels on the inside of each of the two columns, weld 200mm long 16#a channel steel at the lower part of the corbel as a slider, and paste and weld stainless steel plates inside the channel steel. At the same time, the slideways are set inside the steel columns on both sides. The slideway is located on the center line of the concrete beam, and the lower part of the slideway beam is set up with 24#b I-beam as a support, so that the track is 20cm higher than the concrete beam. The 304 stainless steel plate is fully paved on the slideway beam and welded firmly with the slideway beam. Apply silicone grease lubricant to the stainless steel when using. The structural diagram of main span steel roof truss column corbels and sliders is shown in Figure 1-Figure 2 .
[0011] Such as figure 1 As shown, a corbel device is installed inside the steel column, and the corbel device is used as ...

The invention discloses a construction method for traction slip mounting of a light rail station special-shaped steel structure on an operation line. The construction method depends on mounting engineering of the special steel structure and is a novel method designed according to the requirements that the mounting engineering of the large-span special-shaped steel structure is high in construction difficulty, short in construction period and narrow in construction site, and in-situ hoisting cannot be conducted. The innovative point of steel structure traction slip construction is that corbel structures are additionally arranged on the side faces of steel structure stand columns to serve as supporting force transmission points and limiting devices of overall slip, and through analysis of structural inner force and deformation distribution under various working conditions, steel structure posture analysis and overall stability control, the structural posture can be timely adjusted, the limiting effect preventing overall deviation of the steel structure can further be achieved, and traction safety is guaranteed.
Description
technical field [0001] The invention relates to a construction method for traction and sliding installation of a special-shaped steel structure of a light rail station on a running line, and belongs to the technical field of light rail station construction. Background technique [0002] The Zhangguizhuang Station Project of the Jinbin Light Rail is a continuation project of the Zhangguizhuang Station Phase I project of rapid rail transit from downtown Tianjin to Binhai New Area. This project is mainly to build a reserved station under the condition of ensuring the normal operation of Zhangguizhuang Station. The span of the station is 17.20 meters, the column spacing is 9.6 meters, and 12.8 meters. The overall structure is a "station-bridge integration" frame structure. The load-bearing structure needs to be installed under the normal operation of the light rail as an arched steel frame hinged at both ends. The installation and construction of the large-span special-shaped st...
