AI Technical Summary

Technical Problem

The existing bridge prefabricated plate support frames are prone to wear during use and cannot be reused. They are not stable when the bridge has a certain slope, making it difficult to insert wedges.

Method used

A bridge prefabricated plate support device is designed, including a base plate, a pillar, a hinge plate, a support plate and an adjustment cylinder. Through the combination of a hinge plate and an adjustment cylinder, the support plate can adjust the angle to adapt to different slopes, and a protective plate is provided on the support plate for disassembly and replacement.

Benefits of technology

It realizes multiple use of the support frame, reduces waste, improves the stability and operation convenience of the support frame, and adapts to various slope requirements in bridge construction.

Abstract

The utility model discloses a bridge precast slab supporting device, and relates to the technical field of bridge construction auxiliary equipment. The technical problems that in the installation process of a bridge prefabricated slab, the waste rate of a supporting frame is high, and when a bridge has a certain gradient, stability is not high and a wedge is very difficult to insert due to a gap between the supporting frame and the bridge prefabricated slab are solved. Comprising a bottom plate connected to the top end of a supporting frame; the supporting columns are symmetrically installed on the upper surface of the end of the bottom plate, and hinge rods are rotationally installed on the two supporting columns correspondingly; and the hinged plate is arranged between the two supporting columns, the hinged plate is rotationally connected with the supporting columns through hinged rods, and the top end of the hinged plate is connected with a supporting plate used for supporting a bridge precast slab. The angle of the supporting plate can be accurately adjusted by controlling the output distance of the adjusting air cylinder, so that the supporting plate is kept in a horizontal or inclined state, various gradient requirements during bridge construction can be met, stability is high, and operation is convenient and fast.
