Abstract

The utility model discloses a rolling and sliding type building aseismatic device comprising an upper cover disc and a bottom disc which are opposite. A sliding bottom disc is arranged in the bottom disc; at least two steel balls are arranged in the sliding bottom disc; the upper end of each steel ball exposes from the sliding bottom disc; the upper cover disc is arranged on the steel balls; the internal diameter of the upper cover disc is larger than the external diameter of the sliding bottom disc; the lower end of the upper cover disc is connected with the upper end of the bottom disc through bolt connecting blocks; and the inner wall of the upper cover disc and the inner wall of the bottom disc are both provided with rubber rings. Because a plurality of steel balls are arranged between the upper cover disc and the bottom disc, and the steel balls have smaller diameters, when earthquake happens, the steel balls rolls less, and a building swings less horizontally, thus the damage of transverse seismic waves to the building can be reduced to the maximum extent; in addition, all the steel balls bear less weight, so the manufacturing cost of the steel balls are reduced and the building construction cost is reduced.

Description

The slidingtype Shock-proof for building device of holding concurrently rolls
Technical field
The utility model relates to Shock-proof for building, specifically, is a kind of rolling slidingtype Shock-proof for building device of holding concurrently.
Background technology
In recent years, global earthquakes is frequent, brings great harm for the human security of the lives and property.The seismic wave that earthquake produces makes building produce the rippling of vertical direction and the roll and pitch motion of horizontal direction, and the destructive power maximum is to make building produce the laterally seismic wave of horizontal direction.At present, the building industry adopts the method antidetonation that increases building rigidity and intensity usually, has increased building costs greatly, and makes the main part of building seem that the eldest child is stupid thick, and usable floor area dwindles.
Chinese patent ZL200320105021.7 discloses a kind of building tumbling-type vibration abatement, constitute by last, sliding chassis and steel ball, go up, have on the sliding chassis steel ball rolling channel in opposite directions, steel ball is loaded on, between the raceway of sliding chassis, the top of upper cover plate and the bottom of sliding chassis are equipped with pre-buried column.In when construction, the sliding chassis of some pairs of vibration abatements is embedded in above the basic concrete stake, upper cover plate is embedded in below the grade beam, like this, reaches shockproof purpose.Yet, owing to have only a steel ball between last, the sliding chassis, the load-bearing of steel ball is required strict, the cost height, and the diameter of steel ball is bigger, and the displacement of rolling is corresponding bigger, when earthquake took place, the distance of building teeter was big, caused the building vibration; Because this vibration abatement can only reduce the destruction that seismic wave laterally causes building, to seismic wave not effect basically vertically, therefore, shockproof effect is limited again.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rolling slidingtype Shock-proof for building device of holding concurrently, and this vibration abatement lowers the destruction that seismic wave causes building by a plurality of steel balls, and shockproof effect is good.
To achieve these goals, the technical solution of the utility model is: a kind of rolling slidingtype Shock-proof for building device of holding concurrently, comprise in opposite directions upper cover plate and chassis, sliding chassis is housed in the chassis, steel ball more than 1 is housed in the sliding chassis, sliding chassis is exposed in the upper end of this steel ball, on steel ball, be placed with described upper cover plate, the internal diameter of this upper cover plate is greater than the external diameter of described sliding chassis, and the lower end of this upper cover plate is connected through the bolt contiguous block with the upper end on described chassis, at the inwall of upper cover plate and the inwall on chassis rubber ring is housed all.
The utility model is equipped with the steel ball more than 1 in sliding chassis, to reduce the load-bearing of steel ball, reduce the cost of steel ball; And, because the load-bearing of steel ball reduces, therefore, the corresponding diameter that dwindles steel ball, when earthquake took place, the displacement that steel ball rolls was little, and the amplitude of building horizontal hunting reduces, and can farthest resist laterally seismic wave to the impact of building; When the collision of upper cover plate and sliding chassis, the rubber ring of the inwall by being installed in upper cover plate cushions.During installation, upper cover plate and chassis are installed in respectively on geosphere fine strain of millet and the pile foundation, upper cover plate is realized relative translation by steel ball, like this, resists laterally seismic wave by the horizontal hunting of building.
As improvement of the present utility model, the external diameter of described sliding chassis is less than the internal diameter on described chassis.
Improve as of the present utility model another, the soffit on described chassis is provided with rubber pad.
Improve as of the present utility model another, the cross section on described upper cover plate, sliding chassis and chassis is " U " shape.
As another embodiment of the present utility model, upper surface at described upper cover plate is installed with back-up ring, second steel ball more than 1 is housed in this back-up ring, back-up ring is exposed in the upper end of this second steel ball, on second steel ball, be placed with second upper cover plate, the internal diameter of this second upper cover plate is greater than the external diameter of described back-up ring, and the lower end of this second upper cover plate is connected with the upper end second bolt contiguous block of described upper cover plate, at the inwall of second upper cover plate second rubber ring is installed.Further increase building to the impact resistance of seismic wave laterally by two overlapping shockproof dish unit up and down, can be used for the higher building of floor.
Compared with prior art, the beneficial effects of the utility model are:
(1) a plurality of steel balls are installed between upper cover plate and the sliding chassis, the diameter of steel ball reduces, when earthquake takes place, the displacement that steel ball rolls is little, building horizontal hunting amplitude is little, and farthest reducing laterally, seismic wave guarantees that to the destruction of building the center of building is subjected to dynamics;
(2) because the load-bearing of each steel ball reduces, the processing cost of steel ball is low, has lowered the construction cost of building;
(3) the utility model can prevent that not only laterally seismic wave is to the destruction of building, can also reduce longitudinally seismic wave to the destruction of building by pad, through simulated test repeatedly, the shock strength that building of the present utility model is installed is 3-7 a times of common building thing, can be widely used in school, hospital, station waiting lounge and other large-scale public place, and the civilian construction of higher level.
