Wedge-shaped unloading device for bent cap supporting system

Abstract

The invention relates to a wedge-shaped unloading device for a bent cap supporting system, which comprises a base and a sliding module, the base comprises two groups of supporting side plates and a flat plate, a plurality of groups of cross rods penetrate between the two groups of supporting side plates, and core penetrating rods are inserted between the groups of cross rods and the lower end surface of the flat plate; the sliding module comprises a first wedge-shaped sliding block and a second wedge-shaped sliding block, square holes are formed in the vertical end face and the inclined end face of the first wedge-shaped sliding block and the vertical end face and the inclined end face of the second wedge-shaped sliding block, a screw rod penetrates through the square holes in the first wedge-shaped sliding block and the second wedge-shaped sliding block, and the size of the square holes is larger than the outer diameter of the screw rod. The two ends of the screw are in threaded connection with fastening nuts, and the fastening nuts abut against the first wedge-shaped sliding block and the second wedge-shaped sliding block respectively. Sliding of the second wedge-shaped sliding block along the first wedge-shaped sliding block is convenient to control, and the precision requirement of the control process is high; the upper end face of the second wedge-shaped sliding block is separated from the cover beam, and the dismantling process of the whole supporting system is convenient, fast and efficient.

Description

technical field [0001] The present application relates to the field of bridge construction equipment, in particular to a wedge-shaped unloading device for a cap beam supporting system. Background technique [0002] Highway and bridge engineering refers to the planning, design, construction, maintenance, and repair of structures that cross waters, valleys, and all traffic passages. Highway lines pass through rivers, harbors, lakes, reservoirs, irrigation canals and other waters, or across deep valleys with large height differences, or across other traffic lines. Bridges need to be erected to keep traffic flowing. Busy urban areas sometimes require viaducts consisting of viaducts. The side mountain route is sometimes built with a viaduct instead of a roadbed, either because of the huge excavation of the roadbed, or because of the unstable geological structure, or because of the protection of the landscape. [0003] In the construction process of highway bridge engineering, i...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the process of bridge pier construction, the construction of the cover beam piercing rod is required, and in the specific operation process, it is necessary to set up the unloading device to adjust the elevation of the support system , in order to facilitate the adjustment and control of the elevation of the cover beam entity and the subsequent dismantling operations. At present, there are many unloading devices such as jacks and sand drums. In actual construction, due to the influence of sand density in the sand drum and other reasons, it is easy to have low elevation control accuracy and dismantling. Difficulties, etc. arise, so there is room for improvement
