Abstract
The utility model belongs to technical field of bridge, discloses a kind of lead core rubber support.Form the main technical schemes of this lead core rubber support: the upper bracket mechanism be made up of embedded board, upper junction plate at the bottom of beam, the undersetting mechanism be made up of lower connecting plate, in above-mentioned upper and lower junction plate, be provided with corresponding ring-like inner chamber in the heart, the support body that two ends are provided with upper and lower shrouding is fixed in upper and lower ring-like inner chamber; At the bottom of beam between embedded board and upper junction plate, lower connecting plate is provided with respectively with beam body and the fixing upper and lower anchoring mechanism of bridge pier.This lead core rubber support have overall performance good, install, convenient disassembly and there is shearing force disperse the feature that average isolating affection is good, effectively can weaken the impact of different earthquake frequency vibration on building structure.
Description
Technical field
The utility model belongs to bearing technical field, particularly relates to a kind of bridge, lead core rubber support that building engineering field uses.
Background technology
For bridge, building structure realizes and effective damping mainly adopts vibration absorption and isolation support.Lead for retractable pencil bearing is as shown in Figure 1 exactly that use at present a kind of has the bearing subtracting shock insulation function, its structure is formed by being provided with the bearing upper plate of the anchoring mechanism 1 fixed with beam body, the bearing lower plate being provided with the anchoring mechanism 2 fixed with bridge pier and the support body 3 be sandwiched between the two, and the upper junction plate 4 wherein forming bearing upper plate and the lower connecting plate 5 forming bearing lower plate are connected and fixed respectively by bolt 6 and support body 3.The bearing of this structure can bear the gravity of works, load and horizontal force, can also make upper and lower part taphrogeny isolation by the shear strain of himself; But because support body in structure 3 is by being bolted to connection between upper and lower shrouding and upper and lower junction plate; Therefore there is complex structure, poor flatness that centering is poor, each bolt is different pretightning force causes bearing and bearing each bolt strained uneven problem impacting the overall discontinuity of bearing when bearing shearing can be caused because of mismachining tolerance, finally affect the application life of bearing.
Utility model content
The purpose of this utility model be just to provide a kind of bearing overall performance good, install, convenient disassembly, overall uniform force, effectively can weaken the lead core rubber support of different earthquake frequency vibration on the impact of building structure.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of lead core rubber support, its structure comprises
The upper bracket mechanism be made up of embedded board, upper junction plate at the bottom of beam,
The undersetting mechanism be made up of lower connecting plate,
Be fixed on support body between the two; Wherein
At the bottom of described beam between embedded board and upper junction plate, lower connecting plate is provided with respectively with beam body and the fixing anchoring mechanism of bridge pier; It is characterized in that, described upper and lower junction plate is provided with corresponding ring-like inner chamber, the support body that two ends are provided with upper and lower shrouding is fixed in described ring-like inner chamber.
In addition, the additional technical feature forming above-mentioned lead core rubber support also comprises:
---the middle part forming described support body is provided with lead for retractable pencil body;
---form between the upper and lower shrouding of described support body and described upper and lower junction plate and be provided with adhesive layer.
A kind of lead core rubber support provided by the utility model compared with prior art has the following advantages: because the support body forming bearing snaps in the ring-like inner chamber of upper sealing plate and lower shrouding, it is structure and manufacturing process is simple, centering is good not only, but also has the feature of installation, convenient disassembly; More importantly, make support body have shearing force and disperse the feature that average isolating affection is good; Improve the overall performance of bearing on the whole, add the safety of integrated engineering.
Accompanying drawing explanation
Fig. 1: be the structural representation of prior art lead core rubber support;
Fig. 2: be the structural representation of the lead core rubber support that the utility model provides.
Detailed description of the invention
Be described further below in conjunction with the concrete structure of the drawings and specific embodiments to a kind of lead core rubber support provided by the utility model.
As shown in Figure 2, for the structural representation of a kind of lead core rubber support provided by the utility model, namely the upper bracket mechanism that seat structure is made up of embedded board at the bottom of beam 7, upper junction plate 4 is formed, the undersetting mechanism be made up of lower connecting plate 5, in above-mentioned upper and lower junction plate, be provided with corresponding ring-like inner chamber 8 in the heart, the support body 3 that two ends are provided with upper and lower shrouding 9,10 is fixed in upper and lower ring-like inner chamber; At the bottom of beam between embedded board and upper junction plate, lower connecting plate is provided with respectively with beam body and the fixing upper and lower anchoring mechanism 1 and 2 of bridge pier.
In addition, in the structure forming above-mentioned lead core rubber support:
---can bear gravity load and the horizontal force of works to improve this structural bearings further, overall performance when upper and lower part taphrogeny can also be isolated by the shear strain of himself, the middle part forming described support body is provided with lead for retractable pencil body 11;
---in order to improve the overall performance of this making further, between the formation upper and lower shrouding 9,10 of support body and the ring-like inner chamber 8 of upper and lower junction plate, be provided with adhesive layer 12.
