Abstract

The invention discloses a large-span box-type steel beam sliding installation construction process and device, and relates to the technical field of structural engineering. Thick rail pressing platesare arranged on the upper portions of the two sides of the lower end of a sliding rail, a jig frame and a wedge-shaped clamping block are arranged at the upper end of the sliding rail in a sliding mode, square steel is fixedly arranged on the two sides of the upper end of the jig frame, a to-be-installed steel beam is clamped at the upper end of the jig frame through the square steel, and a pushing lug plate is arranged on the outer surface of the to-be-installed steel beam; the fixed end of a hydraulic oil cylinder is rotationally connected with the pushing lug plate, a hydraulic crawl deviceis in rigid connection with a to-be-slid component, and the connection mode is good in synchronism control over all sliding (pushing) points when the sliding span and the spacing distance are large and the number of trusses is large, so that the problem that the in-place accuracy of the steel beam is not high is solved; and the assembly and accumulated slippage of each unit structure can be constructed at the same time and do not influence each other, and the absolute time of hydraulic slippage operation is short so that the installation period of a roof box girder can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a large-span box-shaped steel girder sliding installation construction technology and device. Background technique [0002] With the strengthening of the country's economic strength and the needs of social development, large-scale industrial and public buildings such as large-span industrial plants, waiting halls, exhibition centers, theaters, and stadiums continue to emerge, and the space steel structure has achieved unprecedented development. Wide range of applications. Especially in the construction of some large factory buildings and stadiums, the roof is full of long-span steel beams, especially the industrial factory buildings and stadiums with steel structure roofs, because the overall structure of the construction is lighter (compared with the concrete structure), and the construction period is short. , and can solve the problem of large spans in many indu...
