Abstract
The utility model pertains to the field of bridge shock insulation support technology, and discloses a limited bridge shock insulation rubber support, which has main technical characteristics: the support includes a top board and a baseboard, the transversal position of the baseboard is fixed with a limited guide plate through bolts, a stainless steel plate guide strip is provided on the top end of the limited guide plate, a stainless steel plate slide strip is provided on the top board, and the stainless steel plate guide stripe is matched with the stainless steel plate slide stripe. The lateral displacement of the limited bridge shock insulation rubber support of the utility model is limited by the limited guide plate, so that the shock insulation rubber support can only generate shearing deformation along the bridge direction or designed unidirectional displacement direction. A sliding friction pair composed of the stainless steel plate guide strip and the stainless steel plate slide stripe is provided, so that the friction force during the unidirectional shear displacement of the shock insulation rubber can be decreased.
Description
Technical field
The utility model belongs to isolation bridge bearing technical field, relates in particular to a kind of spacing bridge shock insulation rubber bearing.
Background technology
The shock insulation rubber bearing technology begins to introduce China from the nineties in last century, generally is applied in building constructions and bridge construction aspect, to solve seismic forces to house and destruction of bridge.The isolation bridge neoprene bearing is installed between bridge and the pier, satisfy fixing, monodisplacement and multidirectional displacement request.Do not having under the situation of external force constraint, the isolation bridge neoprene bearing can satisfy fixing and multidirectional displacement request, but is difficult to satisfy the monodisplacement requirement.
The utility model content
Problem to be solved in the utility model just provides a kind of spacing bridge shock insulation rubber bearing that satisfies the monodisplacement requirement.
For addressing the above problem, the technical scheme that the spacing bridge shock insulation rubber bearing of the utility model adopts is: comprise top board and base plate, there is spacing guide strip the suitable direction across bridge position of described base plate by bolt.
Its additional technical feature is: the top of described spacing guide strip is provided with the corrosion resistant plate gib block, and top board is provided with the corrosion resistant plate draw runner, and corrosion resistant plate gib block and corrosion resistant plate draw runner are complementary; Described corrosion resistant plate gib block and the corrosion resistant plate draw runner 3-5mm of being separated by.
Spacing bridge shock insulation rubber bearing provided by the utility model compared with prior art, there is spacing guide strip the suitable direction across bridge position of base plate by bolt.Like this, the lateral displacement of shock insulation rubber bearing is subjected to the restriction of spacing guide strip, make shock insulation rubber bearing can only along bridge to or design monodisplacement direction produce shear strain, thereby satisfy the monodisplacement requirement.And the sliding friction pair that corrosion resistant plate gib block and corrosion resistant plate draw runner constitute is set, the frictional force in the time of then can reducing the unidirectional shear displacemant of shock insulation rubber bearing.
Description of drawings
Accompanying drawing is the structural representation of the spacing bridge shock insulation rubber bearing of the utility model.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the spacing bridge shock insulation rubber bearing of the utility model.
As shown in the figure, the spacing bridge shock insulation rubber bearing of the utility model comprises top board 1 and base plate 2, the suitable direction across bridge position of base plate 2 is fixed with spacing guide strip 4 by bolt 3, the top of spacing guide strip 4 is provided with corrosion resistant plate gib block 5, top board 1 is provided with corrosion resistant plate draw runner 6, corrosion resistant plate gib block 5 is complementary with corrosion resistant plate draw runner 6, corrosion resistant plate gib block 5 and corrosion resistant plate draw runner 6 3-5mm of being separated by.
When the spacing bridge shock insulation rubber bearing of the utility model uses, spacing guide strip 4 is fixed on the base plate 2 by bolt 3.During use, the lateral displacement of shock insulation rubber bearing is subjected to 4 restrictions of spacing guide strip, make shock insulation rubber bearing can only along bridge to or design monodisplacement direction produce shear strain, thereby satisfy the monodisplacement requirement.And corrosion resistant plate gib block 5 and the sliding friction pair that corrosion resistant plate draw runner 6 constitutes are set, the frictional force in the time of then can reducing the unidirectional shear displacemant of shock insulation rubber bearing.
