Description
Technical field
The invention belongs to seismic technology engineering field, particularly a kind of universal elasticity for being used in level in longspan structure
Bearing.
Background technology
Existing bidirectional spring hinged-support is developed on the basis of bidirectional sliding support, is widely used in big across knot
Structure, it is possible to achieve following functions：First, the turning power with all directions；2nd, the vertical load that can be produced superstructure is passed
It is delivered to lower support structure；3rd, by designing the level of a direction that suitable spring rate can produce superstructure
Load bearing part is delivered to lower support structure；4th, it can allow for structure and limited slip carried out in this horizontal direction.
The construction of bidirectional spring hinged-support as illustrated in the accompanying drawings from 1 to 3, mainly by upper bracket plate 1, the first stainless steel plate 2, first
Polytetrafluoroethylene (PTFE) plane slide plate 3, middle spherical plate 4, polytetrafluoroethylene (PTFE) spherical slide plate 5, intermediate host 6, the second polytetrafluoroethylene (PTFE)
Plane slide plate 7, the second stainless steel plate 8, lower support plate 9, casing 10, flat spring 11, dust cover 12, the stainless steel of bolt 13 and the 3rd
Plate 14 is constituted.The support style realizes third and fourth above-mentioned function by flat spring, i.e., resist superstructure using flat spring
The horizontal loading perpendicular to flat spring direction produced, while being designed by the rigidity to flat spring, allows bearing suitable
Flat spring direction limited slip.Because flat spring can only provide unidirectional spring rate, such bidirectional spring bearing uses plate
Spring is constructed, and can only be moved in the two directions, complicated or in the case of there is installation deviation if in stress, this branch
Seat can produce the problem of bearing blocks, loses limited spring rate and limited sliding function in sliding process.
The content of the invention
It is an object of the invention to provide a kind of universal horizontal elastic support, existing spring fastening is solved issuable
Spring blocks, loses limited spring rate and the limited technical problem of sliding function.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of universal horizontal elastic support, including be connected with superstructure upper bracket plate, be connected down with substructure
The horizontal resiliency device being provided between support plate and upper bracket plate and lower support plate, the downside surface of the upper bracket plate is provided with
One group by rule arrange indent contact cave, the horizontal resiliency device be one group contacted with indent cave correspondingly it is vertical
Cantilever rod iron, the cantilever rod iron is by stretching into the bending resistance elastic cone being connected with the downside of the head in indent contact cave and the center on head
Body portion is constituted, and the surrounding on the head contact side wall ring in cave with indent to contacting, and the height on head is less than indent contact cave
Highly, the cave bottom that the top and indent for making head contact cave ensures to leave anticollision space, the top in the bending resistance elastic cone body portion
External diameter be less than the external diameter on head, and also stretch within indent contact cave, the side wall guarantee that contacts with indent cave leaves anticollision
Space, the bottom in bending resistance elastic cone body portion is fixedly connected with lower support plate.
The indent contact cave is distributed in the downside surface of upper bracket plate.
The company's of being provided with groove between the downside surface of the upper bracket plate, two neighboring indent contact cave, the fluting of the even groove
Depth is less than the depth that head is stretched within indent contact cave.
The indent contact cave is in inverted U, is divided into top spherical crown surface and the sidepiece face of cylinder, the greatest circle of top spherical crown surface is straight
Footpath is equal with the cross circular section diameter on the sidepiece face of cylinder.
The head is spheroid, and the diameter on head is equal with the cross circular section diameter on the sidepiece face of cylinder, the bending resistance elasticity
It is up-small and down-big round platform to bore body portion, and the external diameter of upper surface is less than the diameter on head.
Compared with prior art the invention has the characteristics that and beneficial effect：
Seat structure of the present invention is made up of two pieces of support plates and middle horizontal resiliency device, compared with spring fastening
Compare, the vertical load that superstructure is produced can be delivered to the construction of lower support structure by eliminating, i.e., middle spherical plate,
Polytetrafluoroethylene (PTFE) spherical slide plate, stainless steel plate, polytetrafluoroethylene (PTFE) plane slide plate, intermediate host and flat spring, use level bullet
The cantilever rod iron of property device replaces flat spring, and cantilever rod iron lower end is connected to lower support plate, and head and the indent of cantilever rod iron connect
Cave contact is touched, the horizontal loading for any direction that superstructure is produced can contact cave by indent and be delivered to cantilever rod iron, and
Substructure is delivered to by cantilever rod iron.
The present invention realizes different spring rates by designing the diameter and height of cantilever rod iron, that is, adjusts the anti-of cantilever rod
Curved rigidity realizes different spring rates, because cantilever rod iron any level bending rigidity is equal, therefore can realize that bearing edge is appointed
Meaning direction finite stiffness, contacts cave contact with cantilever rod iron, it is any that superstructure is produced by the indent in upper bracket plate
Part of horizontal power can be delivered to substructure by the horizontal loading in direction by cantilever rod iron, realize upper bracket plate any direction
Limited slip function, finally realize the function of universal horizontal elastic support.
Simple structure of the present invention, power transmission clearly, completely eliminate the problem of existing bidirectional spring bearing may be blocked, can be wide
General to be connected applied to architectural bidirectional spring bearing, be particularly suitable for use in roof structure and lower support structure in longspan structure
Be articulated and connected.
