Description
Technical Field
The utility model relates to the technical field of bridge support, in particular to a one-way bridge support.
Background
At present, some bridges with earlier bridge formation years commonly adopt ground angle bolts to be connected with a beam body and pier top stones, so as to play a role in fixing. The ground angle bolts are generally long, and the support is usually installed in place during bridge construction, and then the beam body is hoisted. When the old support is replaced, in order to ensure that the lifting force of the jack acts on the solid web section of the beam end, the jack is usually placed in the transverse bridge direction. The pier top maintenance platform that sets up is convenient for personnel about, and the cat ladder setting is in the side, leads to the general transverse bridge of maintenance platform to be great to the area.
When the above field conditions lead to the replacement of the support, the old support and the new support are taken out and installed by the transverse bridge behind the top body of the beam body basically, and the three schemes mainly comprise:
(1) At least jacking the beam body to the sum of the exposed heights of the upper screw rod and the lower screw rod, then keeping the original upper screw rod and the original lower screw rod, taking out the old support, and then installing the new support to the original support; (2) Cutting off the exposed parts of the original upper and lower screws, taking out the old support, placing the new support at the original support, welding an upper steel plate with an original beam bottom embedded steel plate, and filling the lower steel basin with epoxy mortar; (3) And chiseling part of concrete around the old screw, cutting, namely cutting a part of the original upper and lower screws into the concrete except the exposed part, taking out the old support, placing the new support at the original support, and then re-welding the screws.
The above 3 construction schemes are all feasible, but have respective disadvantages. The first type of beam bottom jacking height is far greater than the standard of 5mm-1cm required by synchronous jacking of the support, and irreversible damage can be generated to the beam body. The second type of new support is not firmly connected with the beam body and the filler stone, and diseases are easy to appear on the new support in the operation process again, so that the normal service life of the support is reduced. Thirdly, although the cutting and welding process is mature and the construction period is short, the cutting and welding are repeated when the support is replaced again, the efficiency is reduced, the economical efficiency of maintenance in the whole period of the bridge is reduced, part of the upper screw rods of the bridge generally penetrate into the beam body and are welded with the pre-buried steel plates at the bottom of the beam, and the repeated cutting and welding can have certain influence on the beam body. Based on the above, the novel bridge unidirectional bearing is provided, which is a problem to be solved in the industry.
