Description
Technical field
The utility model relates to a kind of building structural member, especially a kind of ball hinged support.
Background technique
Ball hinged support is the solid hemisphere protruded with one, is entrenched in a recessed hemisphere, all may be used in any direction
To be freely rotated, displacement of the lines will not be all generated without generating moment of flexure, and in tri- directions X, Y, Z.In order to bear geological process
With other external forces, prevent convex surface ball from deviating from out of concave surface ball, surrounding should be fixed with anchor bolt.Ball hinged support is in multispan or has outstanding
It is widely applied in the large span grid structure of arm.
Summary of the invention
The purpose of this utility model is to provide a kind of ball hinged supports, can flexibly be freely rotated, and resist with outstanding
The performance of vertical tension and horizontal force resistant guarantees that up-down structure does not depart from when earthquake, and has good damping property.This is practical
It is novel the technical solution adopted is that:
A kind of ball hinged support, including convex surface ball plate, concave surface ball plate, fixing bolt, fixture nut, base-plate, support top
Plate, antifriction material；
The base-plate is mounted on bottom structure, and the support top plate is connected to below superstructure；
The convex surface ball plate is arranged above base-plate, and the concave surface ball plate is arranged below support top plate；Convex surface ball
The upward convex spherical of plate is corresponding with the downward concave spherical surface of concave surface ball plate；By fixing bolt and fixture nut by base-plate,
Convex surface ball plate, concave surface ball plate and support top plate connect from bottom to top；
Antifriction material is set between convex surface ball plate and the corresponding working face of concave surface ball plate.
Further, fixture nut is located above support top plate, and spring shim is arranged between fixture nut and support top plate.
Further, antifriction material uses teflon plate or lubricating oil.
Further, bottom structure uses steel column or concrete column.
Further, superstructure uses grid structure.
Utility model has the advantages that
1) ball hinged support does not occur the necking of power, the counter-force for acting on upper and lower structure compares by spherical surface power transmission
Uniformly.
2) with the performance of anti-vertical tension, guarantee that up-down structure does not disconnect when vertical seismic action, and there is good damping
Performance.
3) with the performance of horizontal force resistant, guarantee that up-down structure does not depart from when horizontal earthquake.
4) radial, circumferential displacement request is adapted to, the corner requirement of any direction is suitable for.
5) ball hinged support does not have to rubber pressure-bearing, the influence there is no ageing of rubber to ball hinged support, long service life.
Detailed description of the invention
Fig. 1 is the structure composition schematic diagram of the utility model.
Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
The utility model proposes a kind of ball hinged support, as shown in Figure 1, including convex surface ball plate 1, concave surface ball plate 2, fixed spiral shell
Bolt 31, fixture nut 32, spring shim 4, base-plate 5, support top plate 6, antifriction material 7；
The base-plate 5 is mounted on bottom structure 8, and the support top plate 6 is connected to 9 lower section of superstructure；Bottom
Structure 8 is steel column, concrete column etc.；Superstructure 9 is grid structure, to meet stadiums, hangar, exhibition center roof etc.
The requirement of longspan structure；
The convex surface ball plate 1 is arranged above base-plate 5, and the concave surface ball plate 2 is arranged below support top plate 6；It is convex
Ball plate 1 upward convex spherical in face is corresponding with the downward concave spherical surface of concave surface ball plate 2；It will by fixing bolt 31 and fixture nut 32
Base-plate 5, convex surface ball plate 1, concave surface ball plate 2 and support top plate 6 connect from bottom to top；Convex surface ball plate 1 and concave surface ball plate 2 are distinguished
Using cast steel material machine finishing, accomplish that face surface is round and smooth, to reduce frictional force when rotation；
For the frictional force being further reduced when ball hinged support rotation, ball plate 1 and the corresponding work of concave surface ball plate 2 on convex surface
Make that antifriction material 7 is arranged between face, such as pastes teflon plate or coating lubricating oil；
Fixture nut 32 is located at 6 top of support top plate, and in continuous rotation process spiral shell occurs for ball hinged support in order to prevent
Bolt loosens the extreme cases such as de- limit, and spring shim 4 is arranged between fixture nut 32 and support top plate 6.
The utility model proposes ball hinged support rotation flexibly, bearing capacity is strong, have good anti-seismic performance, in earthquake
Up-down structure not readily disengages from.
It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits
System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
