The middle bottom and top are steel plate layer, and the bridge supports include cylindrical framework of steel reinforcement, and framework of steel reinforcement inner surface covers
Separated explosion-proof layer is stamped, full concrete material is filled in framework of steel reinforcement, the bridge supports outer wall surface is coated with one layer of inorganic layer,
Its short transverse of bridge supports outer wall upper edge is uniformly equipped with several fixed installation rings, is socketed on two neighboring fixed installation ring
The shunting housing of diamond shape, shunting case inside top are fixedly mounted ring with one and connect, and lower part connects with another fixed installation ring
It connects.
Preferably, the inorganic layer surface of the bridge supports is also uniformly provided with several fluorescence warning items.
Preferably, the shunting surface of shell is coated with anti-corrosion layer.
Preferably, it is additionally provided between the shunting inner walls and bridge supports outer wall vertical with shunting inner walls
Assistant reinforcement muscle.
The beneficial effects of the present invention are：
1st, by setting composite joint seat, the stress between bridge supports and bridge pier and displacement can be controlled, is had very strong
Structure ductility and elastic absorbability, make the reliability of bridge supports and safety higher；
2nd, by setting Separated explosion-proof layer in bridge supports, good explosion-proof can be played；By setting inorganic layer,
Make bridge supports that there is good thermal insulation and corrosion resistance；
3rd, housing is shunted by setting, can effectively reduces wind-force or waterpower and be impacted caused by bridge supports, bridge can be extended
The service life of beam stanchion.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiment 1
As depicted in figs. 1 and 2, inorganic explosion-proof bridge stent provided in this embodiment includes bridge pier 1, pontic 2 and bridge branch
Column 3, is equipped with composite joint seat 4 between the bridge supports 3 and bridge pier 1 and pontic 2, composite joint seat 4 include upper sealing plate 41,
Lower sealing plate 42 and rubber support 43, the rubber support 43 are located between upper sealing plate 41 and lower sealing plate 42, and with upper sealing plate 41 and
Lower sealing plate 42 is bonded, and the rubber support 43 includes several layers of 4301 sum number layer steel plate layer 4302 of rubber protective layer, and several layers of rubber are protected
Sheath 4301 and several layers of 4302 alternately stacked setting of steel plate layer, the wherein bottom and top are steel plate layer 4302, jackshaft
42 bottom surface of lower sealing plate of composite joint seat 4 between beam stanchion 3 and bridge pier 1 is fixedly connected with 1 surface of bridge pier, 41 top surface of upper sealing plate
It is fixedly connected with 3 bottom surface of bridge supports, 42 bottom surface of lower sealing plate of the composite joint seat 4 between bridge supports 3 and pontic 2 and bridge
