Abstract
The utility model discloses a high-speed rail falling-off prevention beam, which is arranged between a pier body and a beam body and comprises a falling-off prevention beam stopper. The high-speed rail falling-off prevention beam is characterized in that the surface of the falling-off prevention beam stopper is provided with a plurality of sleeves, and lateral surfaces of the sleeves are provided with threads. The high-speed rail falling-off prevention beam is simple and reasonable in structure, accurate in installation and capable of transversely limiting a bridge structure.
Description
Technical field
The utility model relates to technical field of buildings, the anti-Luo Liang that moves of a kind of specifically high ferro.
Background technology
Anti-fall beam has been installed in the bridge, be for preventing the security performance of beam portion structure under special load effects such as seismic forces, anti-fall beam facility is set between beam and pier, generally be in order to prevent that beam portion from taking place laterally or displacement longitudinally under loads such as seismic forces, during installation and the beam falling prevention stopping block built-in fitting link together, usually be installed in the bearing next door, near central lines of track one side.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple and reasonable, installs accurately, and can implement the anti-Luo Liang that moves of high ferro of cross spacing to bridge construction.
The utility model is to adopt following technical solution to realize above-mentioned purpose: the anti-Luo Liang that moves of a kind of high ferro, be arranged between pier shaft and the beam body, comprise beam falling prevention stopping block, it is characterized in that, described beam falling prevention stopping block surface is provided with several sleeves, and cartridges sides is provided with screw thread.
Described beam falling prevention stopping block and the sleeve that upward is provided with thereof all adopt the quenched and tempered steel structure No. 45, and beam falling prevention stopping block is a rectangular steel plates.
Described sleeve hollow, the top of sleeve is provided with cover plate, and the bottom surface is provided with opening, and it is corresponding with described opening that the beam falling prevention stopping block surface is provided with through hole.
Described beam falling prevention stopping block is installed on beam body bottom by bolt, and the bush whorl length of beam falling prevention stopping block is greater than 1.2 times the diameter of bolt.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model beam falling prevention stopping block surface is provided with several sleeves, and cartridges sides is provided with screw thread, can implement cross spacing to beam portion structure, when Liang Xiangliang needs back timber, can unload the beam falling prevention stopping block bolt, operates in let-down beam stop location, and is easy for installation.

The specific embodiment
As Fig. 1-shown in Figure 4, a kind of high ferro of the utility model is anti-moves Luo Liang, is arranged between pier shaft 1 and the beam body 2, comprises beam falling prevention stopping block 3, and beam falling prevention stopping block 3 surfaces are provided with several sleeves 3-1, and sleeve 3-1 side is provided with screw thread.Beam falling prevention stopping block 3 and the sleeve that upward is provided with thereof all adopt the quenched and tempered steel structure No. 45, and beam falling prevention stopping block is a rectangular steel plates.In the present embodiment, sleeve 3-1 hollow, the top of sleeve is provided with cover plate 3-2, and the bottom surface is provided with opening 3-3, and it is corresponding with described opening that the beam falling prevention stopping block surface is provided with through hole 4.Beam falling prevention stopping block is installed on beam body bottom by bolt, and the bush whorl length of beam falling prevention stopping block is greater than 1.2 times the diameter of bolt.
During the system beam sleeved pre-buried anti-steel plate will be installed and be embedded in the corresponding position of beam body, beam body back in place is moved the beam block by bolt with welding fabrication anti-and is installed on beam body bottom, the anti-slit of moving between beam block and the pinner is 3cm, after treating that the beam body is in place, with slit hardwood jam-pack, when the case beam needs back timber, can unload anti-fall block bolt, operate in the beam falling prevention stopping block position, the beam falling prevention stopping block lateral attitude should be corresponding with pinner position, pier top.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
