For achieving the above object, the utility model provides a kind of bridge earthquake resistance beam tenon structure that falls, comprise superstructure beam and substructure pier, described superstructure beam is shelved on described substructure pier, the bottom surface of described superstructure beam has extended to form hole vertically upward, the end face of described substructure pier has extended to form lower hole vertically downward, the hole of described upper hole and described lower hole arranges in opposite directions, in described upper hole and described lower hole, be inserted with a rigidity barred body, between described rigidity barred body and described upper hole and described lower hole, be provided with sealant.
Preferably, described sealant by asphalt cement described rigidity barred body and described on clog closely knit forming between hole and described lower hole.
Preferably, the internal diameter of described upper hole and described lower hole is 140-160mm, and the degree of depth is 320-380mm.
Preferably, the diameter of described rigidity barred body is 80-120mm.
Preferably, the internal diameter of described upper hole and described lower hole is 150mm, and the degree of depth is 350mm, and the diameter of described rigidity barred body is 100mm.
Preferably, described rigidity barred body is rod iron.
Preferably, described superstructure beam is one, described substructure pier is two of left and right, described superstructure beam be shelved on two described on substructure pier, described in each, the end face of substructure pier is provided with two circular plate type neoprene bearings, and described lower hole has been arranged between two circular plate type neoprene bearings.
The bridge earthquake resistance of the present utility model beam tenon structure that falls has following beneficial effect:
1. the utility model bridge earthquake resistance simple structure of beam tenon structure that falls, consumable quantity is little, and economy is superior, is especially applied in porous more outstanding across its economy advantage on several more bridges.
2. the utility model bridge earthquake resistance beam tenon structure that falls can be realized the beam protection of falling of bridge any direction simultaneously, fills up suitable the bridge of steel concrete and shaped steel block to protection leak, has effectively overcome the defect of prior art existence.
3. the utility model bridge earthquake resistance falls beam tenon structure for " implicit form latch " device, good looking appearance, and overall structure is more safe and reliable.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.

The specific embodiment
Fig. 1 is the fall front view of beam tenon structure of the bridge earthquake resistance of the present embodiment.As shown in Figure 1, the present embodiment proposes a kind of bridge earthquake resistance beam tenon structure that falls, and comprises superstructure beam 100 and substructure pier 200, and superstructure beam 100 is shelved on substructure pier 200.As shown in Figure 4, the bottom surface of superstructure beam 100 has extended to form hole 110 vertically upward, the end face of substructure pier 200 has extended to form lower hole 210 vertically downward, the hole of upper hole 110 and lower hole 210 arranges in opposite directions, in upper hole 110 and lower hole 210, be inserted with a rigidity barred body 300, between rigidity barred body 300 and upper hole 110 and lower hole 210, be provided with sealant (not shown).
Concrete, described sealant is clogged closely knit forming by asphalt cement between rigidity barred body 300 and upper hole 110 and lower hole 210, and rigidity barred body 300 is rod iron, and the internal diameter of upper hole 110 and lower hole 210 is 150mm, the degree of depth is 350mm, and the diameter of rigidity barred body 300 is 100mm.
Exemplary, as shown in the figure, the superstructure beam 100 of the present embodiment is one, substructure pier 200 is two of left and right, superstructure beam 100 is shelved on two substructure piers 200 as shown in Figure 1, the end face of each substructure pier 200 is provided with two circular plate type neoprene bearings 400 as shown in Figures 2 and 3, and lower hole 210 has been arranged between two circular plate type neoprene bearings 400.
Certainly, the utility model bridge earthquake resistance beam tenon structure that falls is also applicable to span≤35m, inherent stress concrete box-beam and the concrete boxlike beam of case chamber width≤3m, in other specific embodiments, the internal diameter of described upper hole and described lower hole can also be 140-160mm, the degree of depth can also be 320-380mm, the diameter of described rigidity barred body can also be other sizes such as 80-120mm, the material of described sealant and rigidity barred body also can need to be adjusted coupling according to design and construction, superstructure beam, substructure pier, the concrete structure quantity of upper hole and lower hole also can be adjusted with structure stress situation as required, repeat no more herein.
Exemplary, the fall concrete applicable cases of beam tenon structure of the bridge earthquake resistance of the present embodiment is as follows:
While making superstructure beam 100 and substructure pier 200, the position that plugs rigidity barred body 300 in setting makes reserving hole build moulding (constructing upper hole 110 and lower hole 210) with steel pipe respectively.Treat that superstructure beam 100 and substructure pier 200 reach design strength, exist together and insert rigidity barred body 300, between rigidity barred body 300 and upper hole 110 and lower hole 210, adopt asphalt cement to clog the described sealant sealing of closely knit formation and fix.Wherein, rigidity barred body 300 is arranged between circular plate type neoprene bearing 400 positions in direction across bridge, in vertical bridge to being arranged on substructure pier 200 end face optional positions (particular location is selected can be needed to regulate according to each structure stress).
In sum, because be arranges between circular plate type neoprene bearing, antidetonation fall beam tenon become " implicit form latch " device, good looking appearance, consumable quantity is little, is especially applied in hole more outstanding across its economy advantage of several more bridges; Can realize the beam protection that falls of bridge any direction, can fill up the suitable bridge of steel concrete and shaped steel block to protection leak simultaneously.
