Description
Technical field
The utility model is related to bridge earthquake resistance device field, and in particular to anti-to a kind of I-shaped Multifunction position limiting girder falling
Shake stop assembly.
Background technology
China is one of most strong country of seismic activity in the world, and national most area is located at high intensity earthquake territory
Domain, earthquake disaster is always one of natural calamity of China's most serious.Bridge as lifeline engineering important component, one
Denier is destroyed in earthquake, can cause huge economic loss and social loss.The bridge in high intensity area is in order to prevent bridge
Vertically and horizontally impact wreckage falls beam accident to beam beam body, it is ensured that the seismic seeurity of bearing, generally packaged using setting limiting block
The earthquake resistant construction put.In Wenchuan earthquake in 2008, the Antivibration block of a large amount of bridges occurs in that different degrees of disease, and causes
Superstructure displacement is excessive or even falls beam event, and ultimately resulting in more bridge needs to take the measures such as beam body reset.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of I-shaped Multifunction position limiting girder falling Antivibration block dress
Put, easily generation is horizontal under geological process for solution bridge, indulges bridge to movement and falls the defect of beam, improves the shock resistance of bridge structure
Energy.
In order to solve the above technical problems, the technical scheme that is used of the utility model for：
A kind of I-shaped Multifunction position limiting girder falling Antivibration block device, including longitudinal block and horizontal block；Longitudinal direction gear
Direction of traffic of the block along bridge is fixedly installed on the edge of bent cap, and it is adjacent that horizontal block is fixedly installed on bridge direction of traffic
Between two beam bodies, the two ends of horizontal block are connected respectively to longitudinal block.
According to such scheme, longitudinal block is connected with damping cushion close to the side of beam body, the horizontal block
Both sides are respectively connected with damping cushion.
According to such scheme, longitudinal block is identical with the height of horizontal block.
Compared with prior art, the beneficial effects of the utility model are：Pass through the beam being arranged on the inside of Antivibration block
Block crimp produces displacement and the seismic energy that dissipates to limit beam body, plays isolating affection；While the I-shaped antidetonation of monoblock type
Block has vertical, horizontal antidetonation position-limiting action, and drawing beam action, and longitudinal direction can be played along the horizontal block that direction across bridge is arranged
Block participates in colliding stress jointly, and restrainer improves the anti-seismic performance of bridge structure.Simple structure of the present utility model, is applied
Work is convenient, with low cost, mechanical model clear and definite, and whole process has given full play to the buffering collision of closed effect of damping cushion, together
When stress is participated in due to longitudinal block and horizontal block jointly, be allowed to more safe and reliable, with preferable future in engineering applications.
Brief description of the drawings
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein：
Fig. 1 is positive schematic diagram when the utility model is applied to bridge；
Fig. 2 is schematic top plan view when the utility model is applied to bridge.
Each label is interpreted as in figure：1- bent caps, 2- bearing cushion blocks, 3- rubber supports, 4- longitudinal directions block, 5- transverse gears
Block, 6- beam bodies, 7- damping cushions.
Embodiment
The upper surface of general bridge bent cap 1 is provided with bearing cushion block 2, provided with common board-like rubber branch on bearing cushion block 2
Seat 3, beam body 6 is positioned on rubber support 3.Antivibration block device described in this case includes longitudinal block 4 and horizontal block 5, indulges
It is arranged to block 4 between the edge of bent cap 1, two adjacent beam bodies 6 of bridge direction of traffic provided with horizontal block 5, transverse gear
The two ends of block 5 are connected respectively to longitudinal block 4, so just form I-shaped Antivibration block.Longitudinal block 4 is close to beam body 6
Side be fixedly connected with damping cushion 7, the both sides of horizontal block 5 have been fixedly connected with damping cushion 7.
Specifically, according to the actual antidetonation needs of bridge structure, in advance by the template of I-shaped Antivibration block and bent cap 1
Template together install by colligation, it is ensured that longitudinal block 4 is identical with the height of horizontal block 5.Then Antivibration block is poured into a mould at scene together
With the concrete of bent cap 1, the damping cushion 7 of cushioning effect has finally been bonded close to the side of beam body 5 in Antivibration block.
The applicable cases of the I-shaped Multifunction position limiting girder falling Antivibration block device of the present embodiment are as follows：In geological process
Under, when the direction across bridge of beam body 6 produces sidesway, longitudinal block 4 of the both sides of beam body 6 can play direction across bridge position-limiting action, hit simultaneously
The effect of hitting will force damping cushion 7 to deform, and play buffering effect of energy dissipation.It is middle when adjacent beam body 6 indulges bridge to the collision that is moved
The horizontal block 5 of setting equally plays spacing and anticollision effect, and can play drawing along the horizontal block 5 that direction across bridge is arranged
Beam action, and vertical bridge participate in collision stress jointly to longitudinal block 4 of arrangement, improve the anti-seismic performance of bridge structure.This dress
The function of shock insulation for taking full advantage of damping cushion 7 and the overall common participation stress of Antivibration block are put, so as to significantly improve bridge
The security of structure.In other embodiments, the damping cushion 7 of the present embodiment can be replaced foamed plastics cushion block or rubber cushion blocks
Deng.The utility model is simple in construction, mechanical model clear and definite, and quick construction is convenient, can be effective by reasonably analyzing calculating
Dissipation seismic energy, reaches the vertically and horizontally spacing purpose of beam body 1, so as to improve the overall anti-seismic performance of bridge structure.
Above-described is only preferred embodiment of the present utility model.For the person of ordinary skill of the art, exist
On the premise of not departing from creation design of the present utility model, several modifications and improvements can be just made without creative work, this
It should all belong to protection domain of the present utility model a bit.
