Description

Deflection bridge device and its installation method

The present invention relates to the improvement of the bridge device and the installation method of the bridge mounted between the bridge and the alternating top plate in the bridge, when the top plate is deformed or when the construction is not parallel to the bridge (shift) receives the vibration, deformation, etc. of the top plate properly The invention relates to a teaching apparatus and a method of installing the same.

Even if there is vibration or deformation of the top plate, the bridge device installed to transmit or absorb the force without difficulty on the side of the pier (shift) side must be interviewed in parallel with the top plate and the pier located above and below to fully exhibit its function.

By the way, the bridge installation work, which is a kind of civil engineering work, can not only have a large allowable design error, but can also be constructed to generate errors beyond the design error. It is not a problem.

However, if the above-mentioned error occurs on the top plate or the pier side interviewing the bridge device as described above, the serious problem, that is, the function of the bridge device is not exhibited at all and even the top plate is separated from the bridge device and placed directly on the bridge. Therefore, there may be a case where the top plate and the gap and the step are generated beside it, and the error generated in this way is proportional to the length of the top plate which is getting longer in order to promote the comfort of the vehicle by minimizing the seams and minimizing the seams. There is a tendency to be enlarged, as shown in the cross-sectional view of the installation state of the prior art shown in Figure 4 is conventionally mounted between the upper plate (1) and the piers (2), between the upper plate 31 and the lower plate 33 A seating device (3) in which a shock absorbing device (34) made of rubber or a predetermined bearing structure is built in a pad, wherein the upper plate of the seating device (3) is provided. The taper plate 6 having the same shape as the gap generated between the sheet 31 and the adhesive plate 11 of the upper plate 1 is welded to the predetermined position of the upper plate 31 at the predetermined position by using a cross-section device. A method of correcting the deflected top plate 1 to be parallel to the piers 2 was adopted by welding and installing the upper surface of the additional tapered plate 6 and the adhesive plate 11.

In the conventional invention made as described above, the taper plate 6 having the same size as the gap generated between the adhesive plate 11 of the deflected upper plate 1 and the upper plate 31 of the chair device 3 is bonded to the adhesive plate 11. By inserting and joining between the upper plate and the upper plate 31, the device 3 can be placed under a parallel structure. In a large bridge, the upper plate 1 is usually a reinforcing steel or steel concrete plate on the I beam called PC beam. Since it is formed integrally, the width and length is more than several 10m, so the stress distribution is uneven during fabrication, so that local warpage is likely to occur, and such warp has a three-dimensional shape in which the aforementioned gap is flat or flat. Machining of the tapered plate 6 to fit the gap is not easy, and the adhesive plate 11, the upper plate 31, and the tapered plate 6 are welded because they are installed on-site by steel or stainless steel. It is not easy to perform heat deformation in a small space, and it is not easy to weld in a narrow space such as a gap formed on the upper surface of the chair. However, since the insertion and welding of the tapered plate 6 by the on-site fitting cannot be precisely adjusted, it is inevitable to construct a bridge that always has a defect.

The present invention has been researched and developed in order to solve the above problems, firstly, it is possible to install a bridge device that can properly exhibit its function even if the bridge deck has its own design error or deformation, and not parallel to the bridge, Secondly, such an installation can be made easily and accurately, and thirdly, to provide a method and a device particularly suited to the method.
