Transverse and longitudinal slippage system for short line-method segment box beam side mold

Abstract

The invention provides a transverse and longitudinal slippage system for a short line-method segment box beam side mold. The transverse and longitudinal slippage system comprises a longitudinal slippage support, a transverse slippage support, a connecting support, reverse buckles I and reverse buckles II, wherein a main body part of the transverse slippage support is formed by group welding of H-shaped steel; a lug plate I is arranged on one end of the transverse slippage support and is connected with a transverse slippage adjusting screw rod, and transverse slippage is realized; a connectinghole is formed in the surface of the transverse slippage support, and the connecting hole is connected with the reverse buckles I; the front end of a main body of the longitudinal slippage support isconnected with a front fulcrum screw of a side mold and is used for supporting a template and a truss of the side mold; the rear end of the main body of the longitudinal slippage support achieves thefunction of supporting the truss of the side mold by connecting a diagonal bracing mechanism and a flange supporting screw; a main body of the connecting support is formed by group welding of I-shapedsteel; two ends of the connecting support are connected with the transverse slippage support; the reverse buckles I are connected with the upper surface of the transverse slippage support; the reverse buckles II are connected with an embedded part of a construction site.

Description

technical field [0001] The invention relates to the technical field of short-line method segmental box girders in bridge engineering, in particular to a transverse and longitudinal sliding system for short-line method segmental box girder side forms. Background technique [0002] In the previous short-line method of section box girder sideform design, the lower bracket of the sideform usually can only slide in one direction, that is, the sideform slides to both sides respectively, and the distance between the sideform and the fixed endform is relatively fixed at this time . In this case, the prefabrication of segmental beams of different lengths can only be realized by adjusting the length of the side formwork covering the matching beam (the length of the matching beam overlapping the side formwork). However, when prefabricating curved beam segments, the matching beam must be covered by side forms at a certain angle. If there are too many overlaps and the covering is not ti...

Problems solved by technology

However, when prefabricating curved beam segments, the matching beam must be covered by side forms at a certain angle. If there are too many overlaps and the covering is not tight, it cannot be prefabricated. At this time, only the fixed end forms can be adjusted. By replacing the end form template and Fix the connecting brackets between the end form brackets to change the overlap of the end form forms, which increases cost and wastes time
