Abstract

The invention provides a segmental box girder prefabricated construction structure, which includes a moving seat, a moving brake wheel, a fixed threaded hole, a hydraulic oil tank, a hydraulic pump, a fixed lifting frame structure, a rotatable clamping seat structure, and a sliding sealing frame that can be plugged. Structure, rotatable and pushable fixed seat structure, rubber plug housing, observation piece, first filling pipe, oil suction pipe, oil outlet pipe and connecting hydraulic pipe, the mobile brake wheels are respectively bolted to the four corners of the lower end of the mobile seat; The said fixing threaded hole is opened in the inner middle position of the moving base. The arrangement of the threaded column, the anti-slip protrusion, the rotating ring, the second fixed seat, the moving seat and the fixed threaded hole in the present invention is beneficial to grasp the rotating ring to rotate the threaded column during use, and the screwed connection between the threaded column and the moving seat is set , It is convenient to carry out fixed work in the process of use, and prevents the sliding of the moving seat from affecting the work during work.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, in particular to a segmental box girder prefabricated construction structure. Background technique

[0002] The segmental box girder with short-line matching method needs to install more embedded pipes during the prefabrication process, and the accuracy of the embedded pipes determines the structure and appearance quality level of the entire segmental box girder. An important part of the box girder, its accurate positioning depends on the accuracy of the position of the bellows. Accurate positioning of temporary prestressing holes and temporary hoisting holes will be the key to balance force when segmental box girder is erected. At the same time, all pre-embedded pipes run through the entire girder body, which is also the most direct and difficult to control link that affects the appearance of the segmental box girder. Therefore, during the prefabrication process, the positioning of th...
