Description

  The present invention relates to a slide bearing device having a waterproof function for structures such as buildings and bridges, and an assembly method thereof.

  An elastic bearing is arranged between the lower arm fixed on the lower structure of a structure such as a building or a bridge and the upper arm fixed on the upper structure, and is fixed on the upper arm and the upper portion of the elastic bearing. A slide support device has been proposed in which a slide plate is used as a slide surface and relative movement in the horizontal direction between the upper structure and the lower structure of the structure is allowed.

  A conventional slide support device is a seismic isolation device that attenuates earthquake energy by friction between an upper rod fixed to the upper structure side and a slide plate fixed to the lower structure side. Therefore, if water or foreign matter adheres to the slide surface, the predetermined performance is not exhibited. For this reason, in the conventional example, the slide surface is covered with a cover in order to prevent water and foreign matter from adhering to the slide surface.

When the elastic member 8 is formed of a high damping rubber, the seismic energy absorption efficiency is improved.

  The size of the horizontal cut surface of the elastic bearing 11 is made smaller than the size of the horizontal surface of the lower collar 4. The lower connecting steel plate 10, the elastic member 8, and the upper connecting steel plate 9 are formed with shear restraining member holes 11 a. The hole 11a for shear restraint member is formed through the upper connecting steel plate 9.

  A shear restraining member 14 is inserted into a shear restraining member hole 11 a formed in the lower connecting steel plate 10, the elastic member 8, and the upper connecting steel plate 9. The shear restraining member 14 is fixed to the elastic support 11 by forming a female thread in the shear restraining member hole 11a formed in the lower connecting steel plate 10 and screwing and fixing to the male screw 14a formed in the shear restraining member 14.

Corrosion of the lower iron 4 and the lower connecting steel plate 10 can be suppressed.

  The construction method of the slide support device for a structure having a waterproof function is as follows: a shear restraining member 14 integrated with an elastic bearing 11 in a female screw hole 4a for a shear restraining member formed in a lower arm fixed to the base 2 of the lower structure 2; The male screw 14a formed at the lower part of the screw is fixed by screwing. Thereafter, the upper structure 3 that has been jacked up is lowered to bring the upper rod 5 into contact with the upper connecting steel plate 9. At this time, the upper end portion of the elastic covering member 12 fixed to the outer periphery of the elastic support 11 comes into contact with the upper collar 5 and functions as a waterproof seal that prevents water and foreign matter from entering the slide surface. Further, the vertical extending portion 12a formed at the lower portion of the elastic covering member 12 is in close contact with the vertical side surface of the pedestal 2a on which the steel plate 13 is wound, or the horizontal extending portion 12b formed at the lower portion of the elastic covering member 12 is provided. By being in close contact with the surface of the lower collar 4h, it functions as a waterproof seal that prevents the infiltration of droplets into the joint surface between the lower collar 4 and the lower connecting steel sheet 10.

  When the inspection work or the replacement work of the support is performed, it is only necessary to lift up the upper structure 3 and release the screwing of the shear restraining member 14 integrated with the elastic support 11 and the lower arm 4. It is possible to remarkably increase the efficiency of the replacement work.

  When a horizontal displacement is applied to the structural slide support device 1 having a waterproof function during an earthquake, the structure slides through the sliding surface between the upper plate 5 and the upper connecting steel plate 9, and the frictional force attenuates the earthquake energy. To do. Since the elastic bearing 11 is restrained from being moved by horizontal displacement by the shear restraining member 14, the elastic covering member 12 fixed to the outer periphery of the elastic bearing 11 can also maintain a waterproof function without being affected by the horizontal displacement. It becomes.

  As described above, according to the slide support device for a structure having a waterproof function and its assembly method according to the present invention, assembly and disassembly can be easily performed, and periodic inspection work can be easily performed. This contributes to cost reduction of the bearing, prevents water and foreign matter from entering the slide surface, and prevents splashes from entering the lower structure.
