Compare with other bridge anti -seismic dogs, the utility model discloses can play the effect of buffering superstructure collision bent cap both sides concrete dog, dissipation earthquake power makes the concrete dog and the roof beam body avoid direct impact simultaneously, prevents transversely to fall the roof beam.
Description
[technical field]
The utility model relates to a kind of bridge shock-proof check block with rubber pad and iron pipe, belongs to bridge construction field of engineering technology.
[background technology]
Existing bridge shock-proof check block is construction measure, be generally concrete block, under seismic loading, Liang Tiyu produces lateral displacement and block generation direct collision, this kind collides as the rigid collision between concrete and concrete, very easily causes block and beam body to destroy, also can make at the bottom of bridge pier pier stressed excessive, unfavorable to bridge construction, under severe earthquake action, easily produce the beam disaster that laterally falls.
Have between small part block and beam body and add rubber mat plate, certain cushioning effect can be played to the collision between beam body and block like this, but be only that common rubber mat plate effect still has some deficits.
The block also had embeds inside concrete, needs to leave cavity on concrete, and process easily makes concrete block produce stress concentration phenomenon under geological process like this, accelerates the destruction of block.
[utility model content]
It is large with Beam pounding power under seismic force effects that the purpose of this utility model is to solve existing block, easily cause beam body and concrete block to destroy and then cause the problem of the beam that laterally falls, a kind of bridge shock-proof check block with rubber pad and iron pipe of rational, easy for installation, good buffer effect is provided.
For achieving the above object, the utility model is achieved by the following technical solutions:
With a bridge shock-proof check block for rubber pad and thin-walled iron pipe, comprise concrete block, be provided with rubber pad between outside concrete block and box girder web, rubber pad has been embedded with some thin-walled iron pipes of cushioning effect, hollow out between adjacent thin-walled iron pipe.
The utility model further improves and is:
Described some thin-walled iron pipes are horizontally disposed with.
Described rubber pad comprises medial surface and lateral surface, and thin-walled iron pipe is arranged between medial surface and lateral surface; The inner side of thin-walled iron pipe is arranged with interior rubber tube, the sheathed outer rubber pipe in outside, and the external diameter of interior rubber tube, the internal diameter of outer rubber pipe are all identical with the diameter of thin-walled iron pipe; Before outer rubber pipe is arranged at medial surface and lateral surface, and three's integral structure that to be time processing shaping.
The thickness of described rubber pad is 12cm, and the diameter of thin-walled iron pipe is 8cm, and the pipe thickness of outer rubber pipe is 4cm, and the distance between adjacent two thin-walled iron pipe axle center is 14cm, and arranges all between two parties.
Described rubber pad is identical with the size of the binding face of concrete block.
Described rubber pad by engineering glue and concrete block glued together.
Compared with prior art, the utility model has following beneficial effect:
The utility model outside concrete block and box girder web between rubber pad is set, the embedded some thin-wall steel tubes of rubber pad, and hollow out between adjacent thin-wall steel tube, rubber pad engineering structure glue is bonded at inside concrete block, thin-walled iron pipe is made to produce plastic strain when beam body and rubber pad clash into, play cushioning effect, have hollow out in the middle of rubber pad, also can produce cushioning effect when beam body and rubber pad collide.Compared with other bridge shock-proof check blocks, the utility model can play the effect of buffering bridge superstructure collision bent cap both sides concrete block, and dissipation seismic forces, makes concrete block and beam body avoid direct collision simultaneously, prevents from laterally falling beam.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the skiagraph that the utility model is arranged on bridge construction.
Wherein, 1 is rubber pad; 2 is thin-walled iron pipe; 3 is concrete block; 4 is medial surface; 5 is lateral surface; 6 is interior rubber tube; 7 is outer rubber pipe.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1 and Fig. 2, the utility model comprises concrete block 3, and be provided with rubber pad 1 between outside concrete block 3 and box girder web, rubber pad 1 has been embedded with some thin-walled iron pipes 2 of cushioning effect, hollow out between adjacent thin-walled iron pipe 2.Some thin-walled iron pipes 2 are all horizontally disposed with.Rubber pad 1 comprises medial surface 4 and lateral surface 5, and thin-walled iron pipe 2 is arranged between medial surface 4 and lateral surface 5; The inner side of thin-walled iron pipe 2 is arranged with interior rubber tube 6, the sheathed outer rubber pipe 7 in outside, and the external diameter of interior rubber tube 6, the internal diameter of outer rubber pipe 7 are all identical with the diameter of thin-walled iron pipe 2; Before outer rubber pipe 7 is arranged at medial surface 4 and lateral surface 5, and three's integral structure that to be time processing shaping.Rubber pad gross thickness is 12cm, and height is identical with width with the height of concrete block respectively with width, thin-walled iron pipe diameter 8cm, and its ring-type outpacking rubber thickness is 4cm, and the distance between two thin-walled iron pipe axle center is 14cm; Thin-walled iron pipe horizontal arrangement and all placed in the middle, arranges that number is determined according to concrete engineering middle cover depth of beam.Rubber pad 1 is identical with the size of the binding face of concrete block 3, and by engineering glue and concrete block 3 glued together.
The utility model is for Continuous Box Girder Bridge, bent cap is built shaping in advance, pile equipment or build puts in place, rubber pad during this use is novel is affixed on outside box girder web, take rubber pad as template, concrete block is built, according to " detection and evaluation of concrete strength standard " (GB/50107-2010), when by 28 day, the length of time reached the compressive strength of self in concrete curing, rubber pad is taken out, spread engineering glue, to fill in outside box girder web and inside concrete block between, itself and concrete block are sticked together.Under geological process, the plastic strain of thin-walled iron pipe and the cushioning effect of rubber pad in rubber pad can be utilized, slow down the collision of beam body and concrete block.
