Description
Technical Field
The utility model belongs to the technical field of the support, especially, relate to an subtract shock insulation steel support.
Background
Seismic waves are divided into longitudinal waves and transverse waves. The longitudinal wave is an elastic wave, is pressed from a source to the propagation direction, is mutually extruded under the combined action of acting force and reacting force, is propagated to the periphery from a linear form, and has higher speed. The behavior on the ground surface is up and down pitching. The transverse wave is shear wave, which is propagated to the periphery like water wave, the speed is slower than the longitudinal wave, and the transverse wave is swayed left and right on the ground. Therefore, people feel the vertical vibration longitudinal wave at first and the shaking transverse wave only after a few seconds. The support used on the bridge comprises a rubber support and a steel support. The rubber support can solve the problems of longitudinal waves and transverse waves, when the service life of the support is considered, more steel supports are adopted, more steel supports are made in the aspect of horizontal shock absorption, the influence on the longitudinal waves is considered less, and the destructive force during the force acceleration of the longitudinal waves is also remarkable.

The to-be-solved technical problem of the utility model is to provide an ability of solving subtract shock insulation steel support of longitudinal wave and transverse wave problem.
In order to solve the technical problem, the utility model discloses a technical scheme does: including last bedplate, middle slider and lower bedplate, lower bedplate top surface is equipped with down the pelvic cavity, and middle slider is equipped with the plane slip friction pair with lower bedplate, the lower part of going up the bedplate is the boss, and the center of boss is provided with the blind hole, the edge on middle slider upper portion be provided with boss assorted basin chamber of going up, the center of going up the pelvic cavity is provided with the center post that matches with the blind hole, go up and be provided with the belleville spring of cover on the center post between bedplate and the middle slider, be provided with the steel sheet spring between middle slider outer wall and the lower pelvic cavity inner wall, the steel sheet spring is connected with middle slider.
The additional technical characteristics are as follows: the top of the lower seat plate is provided with a lower dustproof plate, and the outer edge of the middle sliding block is provided with an upper dustproof plate matched with the lower dustproof plate;
the central column, the blind hole and the disc spring are matched in one or more sets.
The utility model provides a subtract shock insulation steel support, upper seat plate and middle slider no longer direct contact, the lower part of upper seat plate is the boss, and the center of boss is provided with the blind hole, the edge on middle slider upper portion be provided with boss assorted last pelvic cavity, the center of going up the pelvic cavity is provided with the center post that matches with the blind hole, go up and be provided with the belleville spring of cover on the center post between bedplate and the middle slider. The boss, the upper pot cavity, the central column and the blind hole enable the upper seat plate to be connected with the middle sliding block, and the disc spring enables the upper seat plate and the middle sliding block to have a distance with a changeable size. A steel plate spring is arranged between the outer wall of the middle sliding block and the inner wall of the lower cavity, the steel plate spring is connected with the middle sliding block through a bolt, and the steel plate spring has a horizontal wave and horizontal displacement function. Like this, subtract isolation steel support when having ordinary basin formula steel support horizontal shock-absorbing capacity, belleville spring makes to subtract isolation steel support and has vertical elasticity, can solve earthquake's longitudinal wave and transverse wave problem. And the top of bedplate is provided with down the dust guard, and the outer edge of middle slider is provided with the last dust guard that matches with lower dust guard, and lower dust guard sets up with last dust guard is crisscross, prevents that the dust from getting into basin chamber down, ensures the slip of middle slider at basin intracavity down. The central column, the blind hole and the disc spring are matched in one or more sets according to requirements.
