Description
Technical field
The utility model belongs to technical field of bridge, relates to a kind of hyperboloid high resiliency wind resistance pot bearing concretely.
Background technology
The accident that bridge pad is destroyed due to wind action is of common occurrence, in order to improve the use of bearing with the life-span, reduces the replacing of bearing as much as possible, and to reduce its maintenance cost, wind-resistant support has been widely used in cable stayed bridge and suspension bridge engineering field.Along with being showing improvement or progress day by day of bridge technology, high-performance, low cost, steady structure become the demand of wind-resistant support.The design scheme of wind-resistant support normally increases elastic device in support body, and it exists following defect: (1), when one or more spring destroys, bearing can not play the effect of common bearing well; (2) elastic device is exposed to outside throughout the year, easily the corrosion of oxidized and coastal area; (3) cost of production of elastic device, the processing of each parts and quality of fit require higher.
Utility model content
The object that the utility model solves just is to provide that a kind of structure is simple, stable performance, long service life, production and the low hyperboloid high resiliency wind resistance pot bearing of maintenance cost.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of hyperboloid high resiliency wind resistance pot bearing, comprises the end basin and upper bracket plate that can be fixedly connected with bridge pier or king-tower with girder respectively and the bearing functional entity be arranged between the two; It is characterized in that: the piston boit that described bearing functional entity is placed in the pelvic cavity of this end basin by the elastic parts be arranged in basin of the described end and an end, the other end is connected with described upper bracket plate is formed.
The additional technical feature forming above-mentioned hyperboloid high resiliency wind resistance pot bearing also comprises:
---described elastic parts is made up of the cylinder that two curved surfaces are relative;
---described elastic parts is the patty structure of curved surface by two sides;
---the curved surface of described patty structural elasticity assembly mates with the cylindrical shape forming described piston boit;
---the described elastic parts border be combined with described piston boit is provided with sealing ring;
---described piston boit sidepiece is provided with concave station structure, and at the basin of basin of the described end along table top being provided with it fixing shelves ring;
---between basin of the described end and upper bracket plate, be provided with the joint ring dust ring of Wrinkled;
---be provided with wear-resistant slide plate between described piston boit and upper bracket plate.
Hyperboloid high resiliency wind resistance pot bearing provided by the utility model compared with prior art has the following advantages: one, because this bearing is by upper bracket plate, end basin and be arranged at being made up of the elastic parts being placed in end basin body and the piston boit that is connected with upper bracket plate between the two, therefore there is the feature that structure is simple, reasonable in design, the displacement that this structure produces because of the wind-force of transverse direction for bridge, by the new structure of elastic parts, serve good wind resistance cushioning effect; Its two, owing to being provided with wear-resistant slide plate between the piston boit forming bearing functional entity and upper bracket plate, therefore ensure that the friction factor between bearing functional entity and upper bracket plate and wear hardness, improve the application life of wind-resistant support.
Accompanying drawing illustrates:
The structural representation of the hyperboloid high resiliency wind resistance pot bearing that Fig. 1 provides for the utility model;
Fig. 2 is the scheme of installation of upper bracket;
Fig. 3 is the structural representation of the elastic parts forming above-mentioned bearing.
Detailed description of the invention:
Be described in further details below in conjunction with the structure of accompanying drawing to a kind of hyperboloid high resiliency wind resistance pot bearing that the utility model provides.
As shown in Figure 1, 2, the structure of the hyperboloid high resiliency wind resistance pot bearing provided for the utility model and using state schematic diagram thereof.This wind-resistant support comprises the piston boit 3 that pelvic cavity that the elastic parts that is made up of high-strength bolt 12 and the end basin 1 that girder 13 is fixedly connected with, the upper bracket plate 11 be fixed on by foundation 14 on king-tower (or bridge pier) 15, the relative and high elastic rubber plate 21,22 forming gap 16 by upper and lower two cambered surfaces be fixed in end basin 1 pelvic cavity and an end be placed in this end basin to withstand on lower high elastic rubber plate on 22, the other end is connected with upper bracket plate.
Its operating principle is: when the wind-force of direction across bridge blows to bridge, rocking of bridge generation is cushioned, bearing is when direction across bridge displacement, owing to forming the volume invariability of the relative high elastic rubber plate 21,22 of upper and lower two cambered surfaces of elastic parts and buffering can be produced to rocking of producing of bridge by gap 16 between the two, therefore serve the effect of resisting wind-force.And because the elastic parts forming this making is arranged in the pelvic cavity of end basin, effectively overcome it and cause because of exposure it to damage the defect causing the life-span short.
In the structure forming above-mentioned hyperboloid high resiliency wind resistance pot bearing,
---when bearing is in direction across bridge displacement, in order to prevent piston boit 3 to come to nothing in kicking motion phenomenon, piston boit sidepiece is provided with concave station 17 structure, and at the basin of end basin along the shelves ring 5 table top being provided with hexagon socket cap head screw 7 and fixing with it; Between this baffle plate 5 and piston boit 3, appropriate gap is set, ensures the normal pivot angle realizing bearing;
---described piston boit 3 be provided with sunk screw 9 between upper bracket plate 11 and be connected wear-resistant slide plate 8 with piston 3, both well location and fixation had been served, ensure that wear-resistant slide plate 8 is in closing contact state all the time with the corrosion resistant plate 10 be arranged on upper bracket plate, ensure that normal suitable bridge is to displacement.
---in order to extend the application life of high elastic rubber plate, the periphery of high elastic rubber plate 2 and piston boit 3 contact surface being provided with sealing ring 4, rubber tile can being sealed like this, extend the application life of rubber tile;
---in order to ensure the permanent realization of the various functions of bearing, between end basin 1 and upper bracket plate 11, being provided with the sealing and dustproof ring 6 of Wrinkled, improve the application life of bearing.
In addition, form the structure of the elastic parts of above-mentioned hyperboloid high resiliency wind resistance pot bearing, both can be that the high elastic rubber plate relative by two curved surfaces is as described in Figure 1 formed, and the cylinder that this high elastic rubber plate also can improve its elastic performance be further formed; Certainly the patty high elastic rubber plate 19 of this elastic parts can also to be upper side 18 be as shown in Figure 3 curved surface, buffer gap 16 can be produced to rocking of producing of bridge because the upper side 18 of this patty high elastic rubber plate and the bottom surface of pelvic cavity also form, therefore also can reach the purpose of this utility model, the downside 20 of this high elastic rubber plate 19 is the plane or curved-surface structure of mating with the cylindrical shape forming above-mentioned piston boit.The structure of certain this elastic parts of formation is not limited to said structure.
The bearing of this structure not only can girder as shown in Figure 2 and end basin is fixed, upper bracket plate and king-tower (or bridge pier) is fixing uses, equally also can turn around---and girder and upper bracket plate are fixed, end basin and king-tower (or bridge pier) are fixed and used.
