The invention provides steel truss pushing posture control equipment and a posture control method thereof. The equipment comprises a supporting frame, a track beam, transferring devices, multiple first distance measuring sensors, two pushing devices, multiple jacking oil cylinders, multiple second distance measuring sensors and a controller. The track beam is laid on the supporting frame, flange plates are arranged at the two sides of the track beam, and sliding grooves are formed between the track beam and the flange plates. The transferring devices are arranged in the sliding grooves in a sliding manner; the plurality of first distance measuring sensors are mounted on the transferring devices; the two pushing devices comprise rail clamping devices and pushing oil cylinders, the rail clamping devices are installed on the flange plates in a position-adjustable manner, and the pushing oil cylinders are connected to the rail clamping devices; the multiple jacking oil cylinders are installed on the supporting frame, and the multiple jacking oil cylinders are arranged in the length direction of the track beam at intervals; the second distance measuring sensors are installed on the track beam, and the positions of the second distance measuring sensors correspond to the positions of the jacking oil cylinders; and the controller is connected to the pushing oil cylinders, the jacking oil cylinders, the first distance measuring sensors and the second distance measuring sensors. According to the equipment, the problems of high settlement compensation risks and low speed of posture correction of an existing steel truss are solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a steel truss jacking posture control device and a posture control method thereof. Background technique [0002] The on-site assembly and pushing construction technology of steel truss is one of the main construction technologies of steel truss construction. [0003] Before the steel truss is assembled on site, it is generally used to set up a support. A stable and flat support is conducive to the welding construction of the steel truss structure and improves the construction accuracy of the steel truss. After the steel truss is raised, the height is slightly higher than the design elevation of the steel truss, which is convenient for the construction of the beam after the steel truss is pushed up. [0004] Due to the large size and weight of the steel truss, the track beam on the top of the support cannot be completely smooth and level. During the jacking period,...
