Description
Technical field
The present invention relates to the technical fields of bridge earthquake resistance, are specifically related to a kind of bridge and its construction party with antidetonation pin
Method.
Background technique
Bridge due to its can large span construction and be widely used in capital construction, such as make in river and overhead road
With.
Currently, bridge includes bridge superstructure and bridge substructure, bridge superstructure is commonly called as bridge floor, bridge
Substructure is commonly called as bridge pier, support is provided at the top of bridge substructure, by support to the bottom of bridge superstructure
The construction of entire bridge is realized in the support in portion.But existing bridge is that bridge superstructure is placed directly under bridge
In portion's structure, realize that stablizing for the two is installed by the gravity of bridge superstructure.But this structure ties bridge top
Bonding strength between structure and bridge substructure is weaker, is carried in bridge by the accidentally direction across bridge such as earthquake, explosion and collision
When lotus acts on, the problem of easily there is transverse shifting and beam body (bridge superstructure) caused to slide.Although setting can be passed through at present
Limited block realizes cross spacing, and still, limited block volume is big, in the limited situation of bridge superstructure bottom space
It can not be arranged, also, this mode for using limited block to be limited cannot achieve the absorption to energy for rigid limit,
Therefore, the protective value of structure is poor, and application range is small.
Summary of the invention
For the above-mentioned problems in the prior art, it is now intended to provide a kind of bridge and its construction party with antidetonation pin
Method, in the bottom of bridge superstructure, setting is fluted, meanwhile, it is embedded with antidetonation pin in advance at the top of the substructure of bridge
Nail, and antidetonation pin is inserted in groove, so that the connection improved between bridge superstructure and bridge substructure is strong
Degree, reducing bridge structure is not in a possibility that beam body laterally slides when being acted on by accidental direction across bridge load, and by
It is inserted in groove in antidetonation pin, so that being flexible connection between antidetonation pin and bridge superstructure, so that antidetonation
Pin can consume portion of energy, realize the protection to bridge structure, also, antidetonation pin is small in size, can facilitate on bridge
Installation is realized in the limited situation in portion structural base space, usage mode is more flexible, and adaptability is higher, so that it is applicable in
Range is wider.And it provides a kind of for building the construction method of the above-mentioned bridge with antidetonation pin, not only facilitates construction, also benefit
In the stabilization of structure, the safety of bridge construction is improved.
Specific technical solution is as follows:
A kind of bridge with antidetonation pin, including bridge superstructure and bridge substructure, bridge substructure are vertical
It is arranged and its top is provided with support, bridge superstructure is set to the top of bridge substructure, and bridge superstructure
Bottom contacted with support, have the feature that, the setting of the bottom of bridge superstructure is fluted, and groove is located under bridge
The top of portion's structure, meanwhile, the top of bridge substructure is embedded with the antidetonation pin being vertically arranged in advance, and antidetonation pin is upper
End is inserted in groove.
A kind of above-mentioned bridge with antidetonation pin, wherein each bridge substructure is provided with two antidetonation pins,
And two antidetonation pin be symmetrical arranged and be located at the side of support.
Above-mentioned a kind of bridge with antidetonation pin, wherein bridge superstructure is reinforced concrete structure, bridge lower part
Structure is similarly reinforced concrete structure.
Above-mentioned a kind of bridge with antidetonation pin, wherein bridge superstructure is equipped with deck paving, and spreads in bridge floor
The two sides of dress are provided with railing.
A kind of construction method is divided into following steps for building the above-mentioned items bridge with antidetonation pin:
Step S1 builds bridge substructure；
The reinforcing bar for binding bridge substructure, pours the concrete of bridge substructure, and the lower end of antidetonation pin is pre-
It is embedded in the top of bridge substructure；
Step S2 builds bridge superstructure；
The reinforcing bar for binding bridge superstructure is installed with groove in the bottom of bridge superstructure in advance, and by antidetonation pin
Upper end be inserted in the groove of bridge substructure, then pour the concrete of bridge superstructure；
Step S3, stretch-draw prestressing force；
Reach prescribed strength, tensioning bridge superstructure prestressing force to concrete；
Step S4, deck installation structure are built；
Mating formation for deck paving is carried out, and railing is installed in the two sides of deck paving.
The good effect of above-mentioned technical proposal is:
The above-mentioned bridge and its construction method with antidetonation pin, by bridge superstructure and bridge substructure it
Between be provided with antidetonation pin, and antidetonation pin is inserted in the groove of bridge superstructure and realizes soft connection so that
Occur the risk of beam body landing under the influence of earthquake, while can also consume part seismic energy, bridge structure is effectively protected
Shield；Also, antidetonation pin can also enhance bridge structure on the bridge under explosion and collision etc. the accidentally effect of direction across bridge load
Bonding strength between portion's structure and bridge substructure can equally consume portion of energy, play protection bridge beam action；And
And the volume of antidetonation pin is smaller, is not only easy to the construction of bridge, is further adapted to the limited feelings of bridge superstructure bottom space
Condition, usage mode is more flexible, and use scope is wider；And it additionally provides a kind of for building the above-mentioned bridge with antidetonation pin
Construction method not only facilitates building course, is additionally favorable for the stabilization of structure, improves the safety of bridge construction.
