Description

Anti-pulling universal rolling support
Technical field
The present invention relates to a kind of Anti-pulling universal rolling support, belong to building structure earthquake isolation control field.
Background technology
Economic developing rapidly makes people also growing for the demand of large space, and this is promoting the development of space structures undoubtedly, also space structures proposed to higher requirement simultaneously.Large-span space structure from heavy and light, flexible large, damping is little, natural frequency is lower, more responsive to earthquake loading ratio, in large span spatial structure, adopting shock isolating pedestal is comparatively feasible isolation measure.From the study and use situation of large-span structure bearing, in the majority with laminated rubber material and slip steel ball hinged-support.These form of structure have pluses and minuses separately, simply list these several structures mainly foot point not separately below:
(1) neoprene bearing vertically pulling-resistant ability is poor, lacks enough turning powers; Material has time variation, and durability is not enough, is difficult to adapt to the life requirement of large span architecture.
(2), although ball hinged support has certain turning power and horizontal slip ability, structure relative complex, does not have shock insulation ability, simultaneously cannot release temperature stress yet.
(3) in part ball hinged support, increase polytetrafluoroethylene (PTFE)-corrosion resistant plate slide surface, make bearing there is horizontal slip ability.But its horizontal bearing capacity is only the 10%-15% of steel bearing capacity.For meeting vertical bearing capacity, must strengthen the horizontal projected area of bearing, to reduce the stress of polytetrafluoro plate, thereby cause the area of bearing excessive, make horizontal sliding amount also be subject to restriction.
Summary of the invention
The object of the invention is to overcome now backed above-mentioned scarce limit, has proposed a kind of Anti-pulling universal rolling support.The tourelle of this bearing adopts ball, and under Horizontal Seismic Load, the motion by tourelle produces roll displacement, thereby reduces the earthquake input of structure.Because adopting high-strength alloy steel making, ball forms, there is stronger bearing capacity, and friction factor is only 10% left and right of the coefficient of sliding friction, therefore adopt rolling shock insulation device can overcome vertical bearing capacity deficiency or the excessive problem of bearing area of existing polytetrafluoroethylmaterial material.
In order to achieve the above object, the present invention has adopted following technical scheme:
An Anti-pulling universal rolling support, bearing top is covering plate structure, covering plate structure comprises top junction plate 1, upper base plate 2 and rolling plate 3 three parts.Top junction plate 1 is connected with upper base plate 2, and upper base plate 2 is partly connected with the column of rolling plate 3, and three parts are connected to form the whole covering plate structure that forms.Rolling plate 3 is supported on ball 4, and ball 4 is positioned in the seat groove 5 of bottom, and seat groove 5, for roller bearing 4 provides scroll space, makes ball 4 Free-rolling therein.The cavity form connecting between the column of upper base plate 2 and rolling plate 3, the upper board of resistance to plucking cover plate 6 can insert between this cavity when moving horizontally, and between resistance to plucking cover plate 6 lower panel and a groove 5, is fixedly connected with.Seat groove 5 is positioned at the cavity inside that resistance to plucking cover plate 6 bottoms form.
Described top junction plate 1 is connected by interior hexagonal cylindrical hook bolt 7 with upper base plate 2.
Between described upper base plate 2 and rolling plate 3, by interior hexagonal cylindrical hook bolt 8, be connected.
Described bearing general shape is cylindrical shape.
Described top junction plate 1 outward flange leaves bolt hole for being connected with superstructure bolt.
Described Anti-pulling universal rolling support, rolling plate 3 column roots are done chamfering, and chamfering is done in rolling plate 3 ends.
Described Anti-pulling universal rolling support, chamfering is done in resistance to plucking cover plate 6 upper board ends, and lower panel leaves bolt hole for being connected with substructure bolt.
Described Anti-pulling universal rolling support, chamfering is done in base part seat groove 5 middle parts, and while preventing roller bearing rolling, mutual interlock is damaged.
Described Anti-pulling universal rolling support, resistance to plucking cover plate 6 lower ends adopt and are welded and fixed with seat groove 5.
Anti-pulling universal rolling support of the present invention, bears top vertical load by ball 4.Superstructure is fixedly connected with top junction plate 1, and the vertical load of superstructure is delivered on ball 4 by covering plate structure, and reaches a groove 5 to bottom bracing structure by roller bearing 4.Under horizontal force action, top roof structure by bearing can and bottom bracing structure between occurred level displacement, discharge the horizontal stress that superstructure produces.Anti-pulling universal rolling support of the present invention is applied between roof structure and braced structures, and applicability is good.
Anti-pulling universal rolling support simple structure of the present invention, power transmission is clearly reasonable, and material is novel, uniform specification, each is high to stability, and applicability is good, is convenient to make and install, practical.And can effectively discharge the horizontal stress of top roof structure, improve the resistance to overturning of structure.
