The large-span structure aseismatic support comprises a box (1) which is fixed with a steel plate reserved on a large-span steel structure column top, a foundation (2), an upper cover (3) which is fixed with the end part of a large-span steel structure truss, and a ball core (5); the foundation (2) is arranged in a hollow cavity which is formed in the box (1); the upper cover (3) is arranged in the hollow cavity which is formed in the foundation (2); and the ball core (5) is arranged on the contact surface of the bottom of the upper cover (3) and the foundation (2). The large-span structure aseismatic support can effectively improve the aseismatic capacity and can obviously improve the using level of the large-span steel structure roof, has a reasonable design and low manufacturing cost, is convenient and practical, and is convenient to construct in a site. The utility model discloses a convenient and practicable large-span steel structure aseismatic support.
Description
Technical field
The utility model is a kind of large-span steel aseismatic bearing, and particularly a kind of large-span steel aseismatic bearing that is used for stadiums belongs to the renovation technique of large-span steel aseismatic bearing.
Background technology
Along with the quickening of Urbanization in China, building size is increasing, and the class of stadiums requires more and more higher.In the design process of stadiums roof structure, it is not strong that the steel work support displacement ability that quite general problem is exactly a large span is difficult to reach designing requirement, shock resistance.Traditional way is only to strengthen bolt hole improving the displacement capacity of steel work bearing, but that the displacement capacity of this steel work bearing is difficult to reach designing requirement, shock resistance is not strong, and the performance in the actual disaster of earthquake is disappointing.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of large-span steel aseismatic bearing that can effectively improve shock resistance is provided.The utility model is reasonable in design, and is convenient and practical, and the cost cost is not high, and site operation is convenient, can significantly improve the use class of large span steel structure roof.
The technical solution of the utility model is: large-span steel aseismatic bearing of the present utility model, include can with the fixing casing of the steel plate that the large-span steel capital is reserved, base, can with fixing loam cake, the ball core in large-span steel truss end, base places in the set hollow cavity of casing, loam cake places in the set hollow cavity of base, and is provided with the ball core between the contact surface of the bottom of loam cake and base.
Be provided with sphere tetrafluoro plate between the contact surface of the bottom of above-mentioned loam cake and ball core.
Be disposed with the first plane tetrafluoro plate, first corrosion resistant plate between the bottom of above-mentioned ball core and the contact surface of base.
Be disposed with the second plane tetrafluoro plate, second corrosion resistant plate between the bottom of above-mentioned base and the contact surface of casing.
Be connected by connector between above-mentioned base and the casing, be set with flexible member on the connector.
The top of above-mentioned base and casing is provided with dust cover.
The utility model is owing to adopt loam cake to contact with the ball core by sphere tetrafluoro plate, transmit vertical pressure, cambered surface by the ball core makes loam cake can produce the structure of certain corner simultaneously, and in addition, the first plane tetrafluoro plate and first corrosion resistant plate are coordinated the horizontal movement that corner produces simultaneously; The second plane tetrafluoro plate, second corrosion resistant plate provide the integral level displacement of certain distance then can for base, loam cake, ball core.The utility model is according to the requirement of design to support displacement, to the displacement of bearing different directions and corner retrains respectively or relatively large displacement permissible value, thereby make seat structure stressed rationally, can realize the displacement of design assumption and possess better shock resistance that the structure that can significantly improve stadiums is used class.The utility model is applicable to the steel work bearing of all kinds of large spans, has solved bearing distortion in the past, shock resistance deficiency, influences the problem of fabric structure safety.The utility model cost cost is not high, and site operation is convenient, has realized that really the bearing parameter of design is set.The utility model has solved the steel work seat structure displacement capacity of stadiums large spans and the problem of shock resistance, is that a kind of design is ingenious, function admirable, convenient and practical large-span steel aseismatic bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, large-span steel aseismatic bearing of the present utility model, include can with the fixing casing 1 of the steel plate that the large-span steel capital is reserved, base 2, can with fixing loam cake 3, the ball core 5 in large-span steel truss end, base 2 places in the set hollow cavity of casing 1, loam cake 3 places in the set hollow cavity of base 2, and is provided with ball core 5 between the contact surface of the bottom of loam cake 3 and base 2.
In addition, be provided with sphere tetrafluoro plate 4 between the contact surface of the bottom of above-mentioned loam cake 3 and ball core 5.
In addition, be disposed with the first plane tetrafluoro plate 6, first corrosion resistant plate 7 between the contact surface of the bottom of above-mentioned ball core 5 and base 2.Be disposed with the second plane tetrafluoro plate 8, second corrosion resistant plate 9 between the contact surface of the bottom of above-mentioned base 2 and casing 1.
In the present embodiment, be connected by connector between above-mentioned base 2 and the casing 1, be set with flexible member 10 on the connector.
In addition, for reaching dustproof preferably effect, the top of above-mentioned base 2 and casing 1 is provided with dust cover 11.
The span that the utility model embodiment is used for steel structure truss is 70 meters, 8 meters of truss spaces, and the bearing length and width is 650mm, high 300mm; Its structure stress and modification parameter are as follows: pressure is 2500kN; Pull out force is 500kN; Shearing is 350kN; Displacement is ± 30mm; Rigidity is 8kN/mm; Corner is 0.02rad; The implementation structure setting of calculating and have good anti seismic efficiency ideally of above parameter.
The steel plate welding that the utility model is transported to on-the-spot rear box 1 and capital reservation fixes, loam cake 3 can carry after welding with large-span steel truss end, its operating principle is as follows: loam cake 3 contacts with ball core 5 by sphere tetrafluoro plate 4, transmit vertical pressure, cambered surface by ball core 5 makes loam cake 3 can produce certain corner simultaneously, and the first plane tetrafluoro plate 6 and first corrosion resistant plate 7 are coordinated the horizontal movement that corner produces simultaneously; The second plane tetrafluoro plate 8, second corrosion resistant plate 9 provide the integral level displacement of certain distance then can for base 2, loam cake 3, ball core 5.
