Device for moving a bridge shoe and instituting method using

The present invention relates to a moving device of a bridge device that is installed on the top of the bridge supporting the top plate of the bridge to easily install a bridge device that receives the load and deformation of the top plate and a method for installing the bridge device using the move device Invention.

Bridges that connect both eyes across the sea, as well as rivers and rivers, generally have a structure in which the tops are placed on the piers. Even if a cable-stayed bridge (suspension bridge) is installed without a piers, a structure (both piers or columns) supporting the tops in the middle or both sides Since it is installed, it does not deviate from the structure of the top plate and the pier basically.The top plate of the bridge is the pier and the pier or the pier and the alternating bridge (the bridge is located on both sides of the bridge. It is a rigid body that is connected to a vehicle or a human traffic.A large bridge requires a large number of bridges and decks, and heavy decks or trailers for people or vehicles or heavy loads are placed on the deck. As the traffic passes, the dynamic load changes every moment, and the larger the bridge, the longer the top plate. Therefore, the amount of stretching and shrinkage increases due to the change of the season and the heat distortion according to the crossover. In particular, the top plate is not only deformed due to shrinkage and stretching due to the temperature difference in the winter season, but also may be caused by the dynamic load caused by the passing vehicle. If it acts on the bridge, it is installed to be mounted on the bridge through the bridge so that the bridge and the top plate can be always matched without being transmitted to the bridge side by absorbing and buffering it, so that the bridge has sufficient load bearing capacity. It will be able to enjoy a sufficient lifespan.

In addition, such a seating device includes a pad shoe type device having an excellent ability to absorb impact loads, or a port bearing type and oilless type type device having excellent adaptability to displacement. There is a seismic device for seismic or seismic isolation so as not to lose its function even under a large displacement such as an earthquake or the like, and the present invention can be applied to any type of teaching device as it is. Although there is a slight difference, the movement limiting part (buffer) which is installed between the lower plate attached to the pier or the alternating side and the upper plate attached to the upper plate and the upper and lower plates to absorb / support displacement and load However, according to the main functions classified as described above, the movement limiting part Since the shape of the branch is slightly deformed, the moving device of the present invention, which is installed under the lower plate, which is absolutely necessary for any teaching device, will be applied as it is without any deformation.

By the way, even if there is vibration or deformation of the upper plate, the bridge device is installed to transmit or absorb the force without any difficulty on the side of the pier (shift) side. It is fully functional.

However, the bridge installation work, which is a kind of civil engineering work, is not only large in allowable design error, but also tends to be constructed in such a way that an error exceeding the design error occurs. In general, it is common to install while adjusting the position and height of the bridge device (especially the lower plate) by bending the anchor bolt embedded in the pier side or using other subsidiary materials.

That is, in the related art, as shown in FIG. 6, the upper plate 31 mounted with the anchor bolt 34 embedded in the upper plate 1 of the bridge and the anchor bolt 34 embedded in the bridge 2 are provided. In the chair device (3) consisting of a lower plate (32) to be seated by the enemy, and a movement limiting portion (33) interposed between the upper and lower plates (31, 32) to support compression and deformation forces, The nut 341 is provided on the upper and lower portions of the anchor bolt 34 screwed to the anchor hole 311 drilled in the lower plate 31 of 3). By adjusting the height of the lower plate 31 can be adjusted, and this configuration is installed at each of the four corners of the lower plate 31, by adjusting the height of each of them, the leveling of the lower plate 31 accurately (Leveling) accurately For example, the lower plate 31. If any corner is too low to raise this portion, loosen and raise the nut 341 installed on the upper part of the anchor bolt 34, while lowering the plate 31 to a predetermined height of the anchor bolt 34 The nut 341 attached to the lower part is heated up, and when it is positioned in the correct position, the upper nut 341 is heated again to fix the movement of the lower plate 31, and any corner of the lower plate 31 If the height is too high, the position can be adjusted by operating in the reverse order to the above.

However, the conventional invention has a problem that the work is cumbersome and not easy to adjust because the height adjustment should be performed by loosening and exposing two nuts 341 at each corner, and in particular, the anchor embedded and protruding on the pier (2) side. If the bolts 34 are not in the correct position, the above-described method becomes useless. Therefore, the anchor bolts 34 are removed and repurchased, or a separate subsidiary bolt is connected to the anchor bolts 34 (welded) for reconstruction. After that, since the lower plate 31 of the chair device 3 must be installed, the work is cumbersome, and the chair device 3 installed in this way does not have a solid support, so the chair device 3 performs its function even after installation. There were problems that prevented them.

The present inventor not only completely solves all the above problems, but also allows the installation apparatus 3 of any shape to be easily, simply and economically installed, that is, the anchor bolt 34 is accurately positioned due to a design mistake or construction error. In order to be easily applied even if the position is not changed or the installation of the teaching apparatus (3) has been studied to complete the present invention, which can adjust the height while allowing the lower plate to be easily moved to the bottom of the typical teaching apparatus To provide a moving device, and to provide a construction method for installing the teaching apparatus using such a moving device, which will be described in more detail according to the drawings as follows.
