Description

Adjustable beam bottom wedge-shaped device

Technical Field

The application relates to an auxiliary device of a bridge or a building structure, in particular to an adjustable beam bottom wedge-shaped device.

Background

The assembled bridge or building structure is formed by processing and molding in a prefabricated part factory, transporting to a construction site, hoisting and splicing, and has the advantages of short construction period, high construction quality, less environmental pollution and the like compared with the traditional construction mode of binding reinforcing steel bars and pouring concrete on the site, so the assembled bridge or building structure is the development trend of the building and traffic industry in China.

In the field construction process of the assembled bridge or building structure, a precast beam needs to be lifted and erected on a pier or an abutment provided with a support, and due to construction deviation or the gradient of the beam bottom, when the precast beam is erected, the pressure-bearing support below the precast beam is prone to bias pressure, local void and even complete void.

In order to avoid this problem, the local bearing area of the bottom of the fabricated precast beam, which is in contact with the support, should be provided with a bottom wedge block. Through the leveling function of the beam bottom wedge-shaped block, the beam bottom and the bearing surface of the support are in a horizontal state or a state close to the horizontal state, the load transmitted by the upper structure can be ensured to vertically act on the top surface of the support, the horizontal component force borne by the support is eliminated or reduced, and the plane climbing of the upper structure of the bridge, the bias of the support, the support falling and the like are avoided. But at present, most precast beams are not provided with beam bottom wedge blocks from the industrial condition. Even some assembled precast beam's beam bottoms have set up the beam bottom wedge, but because the beam bottom wedge that finishes of prefabricating is with precast beam integrated into one piece casting shaping, so the position of wedge, the state can't be adjusted, hardly adapt to assembled bridge or building structure's construction deviation, more difficult slope requirement that matches various roof beam bodys and erect, final roof beam body erects and finishes, the slope is personally submitted with support pressure-bearing contact to the beam bottom wedge or local sky state, still finally is difficult to avoid support biasing, support local sky scheduling problem.

More seriously, if a plurality of supports exist below the same prefabricated beam in the construction and erection process of the prefabricated beam, when the elevation construction deviation of the cushion stone at the support is large, a seesaw phenomenon is easily formed among the supports, the distributed counter force among the supports is uneven, the bearing pressure of part of the supports is large, the bearing pressure of part of the supports is small, even the individual supports are completely released to a zero-pressure state, in the subsequent operation process, the supports released to the zero-pressure state are repeatedly flapped due to live load, and finally the supports fall off, so that the structure safety is influenced.

In view of the above problems, the inventor believes that the bridge or building structure provided with the support at present has the following defects: in the construction process of a bridge or a building structure, the bearing state of the support cannot be adjusted, so that the problems of support bias, support emptying, bridge or building structure plane creeping and the like are difficult to avoid.
