The present invention relates to a device and a construction method for correcting and installing the behavior of the integrated elastic support 100, more specifically, calculated through the calculation of the behavior using a distance control bolt 290 that can be finely adjusted to a precise specification It is possible to control the distance to the precise value, it is possible to obtain a stable propulsion reaction force as the rotational force of the electric and hydraulic, through which the correction of the behavior of the integrated elastic bearing 100 can be easily performed, the insertion hole 280 And the lower support block 230 and the upper support portion 220 and the upper support block 320 which are detachable through the fixing protrusion 270 according to the shape of the integrated elastic support 100 having different height standards according to the amount of movement. The present invention relates to a behavior correction device and a construction method of the integrated elastic support 100, characterized in that it is configured in an easy form.

In general, when the construction of domestic bridges with marked temperature changes in four seasons, the expansion behavior is calculated according to the shape, material characteristics, and extension of the upper structure, and expansion joints are installed in the upper slab to cope with the expansion amount and to secure traffic. It is installed in the lower part to transmit the deformation and load of the upper structure of the bridge to the lower structure, and to perform the function of minimizing the effect of the lower structure such as earthquake to the upper structure, the bridge device supports elastic rubber ( 110) The height of the installation is changing.

However, in the construction of the elastic bearings conventionally constructed for seismic performance, the upper and lower plates 120 and 130 and the elastic rubber bearings 110 are not integrated, but are manufactured in a separate form to provide the driving force in the upper and lower plates 120 and 130. Since there is no way to correct the elastic rubber bearing 110 according to the amount of behavior because it cannot be obtained, due to the temperature stretching behavior in the bridge that is hypothesized at a time when there is a lot of temperature change at the reference temperature of 15 ° C, such as early spring and late autumn, summer, etc. There is a case that the elastic rubber support 110 is separated or does not function according to the direction.

It is an object of the present invention to provide a device for correcting the amount of behavior of the integrated elastic support 100 that can easily perform the amount of behavior correction.

In order to achieve the above object, the present invention forms an insertion hole 280 in the lower support portion 210 that is installed to surround the corner of the lower plate 130 of the integral elastic bearing in the U-shape and of the lower support block 230 The fixing protrusion 270 is inserted into the insertion hole 270 by the fixing protrusion 270 at the lower portion, thereby completing the configuration of the lower support portion 210, supporting one end of the upper plate 120, and adjusting the distance adjusting bolt 290. The propulsion reaction obtained in the) to the upper plate 120 and the elastic rubber support 110 and the function, and the induction hole 240 is formed on the rear side, the distance adjustment bolt 290 is inserted into the stable propulsion without slipping or falling off Removable lower support block 230 and upper support through the upper support portion 220 configured to transmit the reaction force, the beggar adjustment bolt 290, which allows fine adjustment of the precise specifications, the insertion hole 280 and the fixing protrusion 270 Amount of motion through block 320 According to the standard height is characterized in that the applicability of the other one-piece resilient foot (100) consists of a readily form.
