Description
Technical field
The utility model relates to earthquake resistant engineering shock insulation field, is specifically related to a kind of high damping shock insulation rubber bearing with stopper.
Background technology
The high damping shock insulation rubber bearing is a kind of novel shock insulation rubber bearing; The basic principle of its shock insulation is through at engineering structure bottom design shock insulation layer; At the shock insulation layer high damping shock insulation rubber bearing is set; Make be able to prolong the natural vibration period of whole engineering structures, utilize the horizontal flexibility of high damping shock insulation rubber bearing to form flexible shock insulation layer together, absorb and the dissipation seismic energy through flexible shock insulation layer; Prevention also alleviates the transmission of seismic energy to superstructure, finally reaches to alleviate the purpose that earthquake destroys superstructure.This seismic isolation technology not only can guarantee the general safety of engineering structures, and the destruction that can prevent non-structure member, also can avoid like interior of building finishing, the damage of indoor equipment and the secondary disaster that causes thus.Existing high damping shock insulation rubber bearing is a kind of horizontal movement relationship type shock insulation rubber bearing; Horizontal equivalent stiffness is little; Under the normal level active force (like strong wind), horizontal distortion can be bigger, is unfavorable for keeping the stability of engineering structures; So the common engineering structure also need be equipped with devices such as shearing trip, thereby has improved the engineering-built cost.
The utility model content
In order to overcome the defective that prior art exists, the utility model provides a kind of high damping shock insulation rubber bearing with stopper.
For reaching above goal of the invention, the utility model can be realized through following technical scheme:
A kind of high damping shock insulation rubber bearing with stopper; Comprise upper junction plate, shock insulation rubber bearing body, lower connecting plate; Said upper junction plate and lower connecting plate are arranged at shock insulation rubber bearing body two ends up and down; Fix through connecting bolt, it is characterized in that: also comprise the stopping means that is arranged at shock insulation rubber bearing body both sides; Said stopping means upper surface is not less than the upper junction plate upper surface, and and upper junction plate between leave spacing displacement space; Said stopping means lower end is connected with lower connecting plate.Described stopping means is fixed through the mode and the lower connecting plate of bolt or welding.The lateral layout of said stopping means has special-shaped load breach.
The beneficial effect of the utility model mainly is: stopping means is the part of bearing; It is the fragility composite material; Under normal level active forces such as strong wind, can play position-limiting action to the horizontal distortion of high damping shock insulation rubber bearing, and in powerful following time of geological process power; The stopping means meeting brittle destruction af-ter of high damping shock insulation rubber bearing does not influence the horizontal large deformation shock insulation power consumption effect of high damping shock insulation rubber bearing.The utility model not only possesses all functions of traditional high damping shock insulation rubber bearing, certain spacing power of level can also be provided, with the structure excess displacement that prevents to be caused by conventional levels loads such as wind loads.The stopping means that has changed existing high damping shock insulation rubber bearing reduces the installation portion number of packages through the technology that shear device produces position-limiting action is set separately, has simplified overall structure, has practiced thrift the space, has reduced cost.
Description of drawings
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the utility model vertical view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is at length explained.
As shown in Figure 1; A kind of high damping shock insulation rubber bearing with stopper comprises stopping means 1, upper junction plate 2, connecting bolt 3, shock insulation rubber bearing body 4, lower connecting plate 5, and described stopping means 1 is arranged at high damping shock insulation rubber bearing body 4 both sides; Be connected with lower connecting plate 5; Fixing through connecting bolt 3, described upper junction plate 2 is arranged at high damping shock insulation rubber bearing body with lower connecting plate 5, and about in the of 4 two ends, and high damping shock insulation rubber bearing body 4 both ends of the surface are provided with screwed hole; Be connected with lower connecting plate 5 with upper junction plate 2, fixing through connecting bolt 3.The making of stopping means 1 is satisfied the spacing displacement of structure design and is designed spacing load.
In the little displacement of the design of high damping shock insulation rubber bearing; The utility model is the same with existing high damping shock insulation rubber bearing, is out of shape through the neoprene bearing occurred level and comes dissipation energy, in the case; Stopping means 1 does not contact with upper junction plate 2, and stopping means 1 is not worked.Under the normal level active force (like strong wind), displacement deformation during the high damping shock insulation rubber bearing takes place, and horizontal loading is when being not more than the spacing load of the design of stopping means 1; Works drives the motion of upper junction plate 2 occurred levels; Upper junction plate 2 contacts with stopping means 1, and stopping means 1 is started working, and restriction upper junction plate 2 continues the occurred level motion; Play the horizontal direction position-limiting action, play maintenance engineering structures stability action.When big displacement deformation takes place owing to reasons such as earthquakes in the high damping shock insulation rubber bearing; Horizontal loading will be greater than the spacing load of design, and works drives the motion of upper junction plate 2 occurred levels, and upper junction plate 2 contacts with stopping means 1; Because horizontal loading is greater than the spacing load of the design of stopping means; Upper junction plate 2 will be cut off stopping means, and the high damping shock insulation rubber bearing recovers the large deformation ability, and the high damping shock insulation rubber bearing will play shock insulation power consumption effect through horizontal large deformation.
Stopping means is fixed through the mode and the lower connecting plate of bolt or welding, and it is relevant with the strength of materials and form of structure that it designs spacing load.In order to guarantee that spacing load is controlled in the scope of design, the strength of materials of stopping means can be selected macromolecular material or metal material for use according to the design Selection that concerns of the horizontal loading of high damping shock insulation rubber bearing and distortion.Can be through adjust its load at the lateral layout of stopping means abnormity load breach.
Description to the foregoing description is to be convenient to engineers and technicians better to understand the utility model; And the personnel of skilled can make various modifications to the foregoing description easily; Therefore, improvement and the modification made according to the utility model thought all should drop within the protection domain of the utility model.
