Description
Technical field
The utility model belongs to civil engineering, and bridge engineering field relates to a kind of structure that ensures bridge superstructure earthquake safety: be particularly related to a kind of high-damping rubber core shock insulation rubber bearing.
Background technology
Under geological process, the beam that falls of bridge superstructure is the one of the main reasons of bridge collapse.In order to ensure bridge superstructure earthquake safety, between the structure of bridge upper and lower part, vibration absorption and isolation support being set is simple, direct, the most economic measure.
In prior art, the damping of common bearing is little, and its damping and isolation effect is bad.Therefore require further improvement.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, discloses a kind of rubber support in layers, is designed to outer interior two parts composition, and outside is layering rubber cylinder, and inside is high-damping rubber core.The utility model high-damping rubber core shock insulation rubber bearing, its simple structure, easy for installation, functional, durability is high, can adapt to the user demand of bridge construction under static(al) and subtract shock insulation demand under geological process.
The technical scheme that the utility model provides is:
A kind of high-damping rubber core shock insulation rubber bearing, is characterized in that, comprises some layers of rubber layer 1, upper junction plate 2, top board 3, trip 4, high-damping rubber core 5, lower connecting plate 6, base plate 7, some layers of put more energy into steel plate 8, connecting bolt 9 and rubber cover 10.Described some layers of rubber layer 1, some layers are put more energy into and are connected to form one by sulfuration process between steel plate 8, top board 3, base plate 7, are column, and the reserved manhole of central authorities.Described high-damping rubber core 5 can be pressed in described reserved through hole by compact heap, axially spacing by upper and lower two trips 4 respectively.The number of plies of described rubber layer 1 and the steel plate 8 of putting more energy into can be determined as required.The described steel plate 8 of putting more energy into is used to provide vertical rigidity.Described rubber cover 10 is coated on column periphery, plays protection column internal construction.The thickness of rubber cover 10 can be determined according to environment temperature and user demand.Top board 3, base plate 7 are individually fixed in upper junction plate 2, lower connecting plate 6 by connecting bolt 9.Described upper junction plate 2, lower connecting plate 6 are connected with the top and the bottom structure of external beam body respectively again.
Described column, radial section is circular or square.
Described connecting bolt 9 adopts high-strength bolt.
The making material of described trip 4 is steel, can be circular or square.
Described upper junction plate 2, lower connecting plate 6 be by whole utility model device respectively with external beam body (or pier) thus top and the bottom structure links together and can form the medium of complete Path of Force Transfer.Upper and lower two junction plates have with outside connected mode: can be by being connected in upper junction plate 2 position, hole reserved with beam body (or pier) with linkage is set on lower connecting plate 6; Some connecting hole positions also can be set on junction plate to be connected with the pre-buried connecting reinforcement on beam body (or pier).
Principle of the present utility model is: under Static behavior, bearing distortion is very little, can ensure the demand under normal use; Under geological process, high-damping rubber core is sheared together with layering rubber column, and now high-damping rubber core can consume energy, and now plays in the layering rubber column of bearing effect each rubber layer damping capacity spy good.That can improve structure subtracts shock insulation characteristic, and layering rubber column can not be damaged under earthquake as the protection structure of high-damping rubber core.
Can overcome and easily expose as lead for retractable pencil kind of design bearing in prior art problems such as causing environment pollution.High-damping rubber core is wrapped in the shock insulation rubber bearing being formed by layering rubber column body, the problem of having avoided high-damping rubber to decline because of the bad isolation property of durability.
The advantage of the bearing that the utility model provides:
1) increased the damping of bridge and fabric structure, reduced the response of structure under geological process, thereby ensured the especially safety at high-strength Structures under Earthquake under geological process;
2) on-the-spot installation is simple, convenient, quality is guaranteed, adopts existing construction technology to can be completely achieved whole technological merits of this utility model, does not need additionally to increase difficulty of construction.
In a word, the utility model is applicable to civil engineering and bridge engineering, can make as the case may be the bearing of different size, thus meet under normal operating condition and geological process under subtract shock insulation demand.
