Abstract
A universal spherical joint supporter with an anti-loosening position-limiting structure comprises a main spherical joint structural part consisting of a main top base with a concave spherical surfaceand a main bottom base with a convex spherical surface; the main bottom base consists of a base body, at least three reinforced plates and a steel ball; the steel ball is a convex ball component arra nged in the bottom base; the reinforced plates are distributed in the bottom base radially and vertically by taking the vertical middle axis line of the steel ball as a central line; each reinforced plate is provided with a vertical edge closely to the middle axial line of the steel ball; a spherical concave position used for bearing the steel ball is arranged on an upper plate of the reinforced plate closely to the middle axis line by taking the spherical center of the steel ball as a center, and a convex claw is arranged in a space between every two adjacent reinforced plates on the main bottom base correspondingly to the lower circumference of the main top base, thus forming the position-limiting structure of the spherical joint. The position-limiting structure can play roles of preventing loosening, restricting the rotation of the top base around the axis line and bearing the pulling force and has excellent bearing performance; and when the position-limiting structure bears the pulling force, the spherical joint part can rotate slightly and simultaneously.
Description
Technical field
The present invention relates to a kind of bearing for building, particularly a kind of universal spherical joint supporter with anti-loosening position-limiting structure, it is applicable in the architectural structure system with big cantilever construction, is used for being connected of rack and stub.
Background technology
In building structure, rack with a plurality of bearing supports that big cantilever or longspan structure and band overhang, because of its bearing temperature load, wind carries or the distortion needs of seismic load, need the bearing support of rack can on both direction, do the trace rotation and not produce linear displacement and bending moment, the general connected node form that adopts the ball pivot pressure supporting seat, ball pivot pressure supporting seat commonly used as shown in Figure 1, it is by base, footstock, spherical hinge structure, be used for being connected with rack or cantilever mast respectively on bolt and the bearing and form with the stub connection structure connecting, wherein, spherical hinge structure is: the solid hemisphere 30 of convex that is arranged on the base matches with mortar formula half recessed ball 31 on being arranged on footstock, for preventing spherical hinge structure to be got loose because of the influence of earthquake or other horizontal force, be 31 disengagings from mortar formula half recessed ball of the solid hemisphere 30 of convex, with crab-bolt 32 base and footstock are connected and fixed around the bearing, but also set up compression spring 33 on the top of crab-bolt 32, so that bearing still can freely rotate and not influenced by the pulling force of crab-bolt by the cooperation of spherical hinge structure.
But also there is following shortcoming in the structure of existing ball pivot pressure supporting seat:
1, the tension of this bearing, shear resistance are not strong, and under the effect of stronger pulling force, shearing, spherical hinge structure is easy to get loose, and promptly the solid hemisphere of convex is easy to break away from from mortar formula half recessed ball, so its load-carrying properties are not high, poor reliability;
2, bearing can not slide, can't release temperature stress, so building unit is subject to damage, thus shorten the application life of bearing;
3, bearing only has single spherical hinge structure, thereby the design factor of being considered in whole building system relatively disperses, and causes the integral design not strong, therefore is unfavorable for the globality design and the construction of building structure.
4, the support node that has has concave surface, is easy to generate problems such as dust stratification, ponding, so that influences the rotating property of bearing, shortens the application life of bearing.
Summary of the invention
First purpose of the present invention is to provide a kind of and improves bearing capacity, strengthen the node reliability and can prolong the universal spherical joint supporter of the band anti-loosening position-limiting structure in bearing application life.
Second purpose of the present invention is to provide a kind of universal pair of hinged-support that has slidably with the band anti-loosening position-limiting structure of release temperature stress on the basis of first purpose.
First purpose of the present invention is to realize by following technical measures: a kind of universal spherical joint supporter with anti-loosening position-limiting structure, the cue ball hinge structural member that comprises main footstock and have the main base formation of protruding sphere with concave spherical surface, and be used on the bearing being connected with rack or cantilever mast respectively and with the stub connection structure connecting, it is characterized in that described main base is by base body, at least three stiffeners and steel ball are formed, wherein, described steel ball is the protruding ball member that is arranged in base body, stiffener is that center line radially uprightly is distributed in the base body with the vertical centering control axis of steel ball, each stiffener all has a vertical edges near described steel ball axis, simultaneously, to be the center of circle have the circle that is used for the support steel ball on the upper board of stiffener near described axis part lack recess with the steel ball centre of sphere, and the circle of several stiffeners lacks the recess acting in conjunction, and fixedly support is therein with steel ball; Space between every adjacent two stiffeners one dog is set in the lower periphery of described main footstock on corresponding to main base, so that described dog stretched into space between the stiffener when main footstock was cooperated with main base, steel ball is wrapped in several dogs encloses in the space of drawing together, form the position limiting structure of ball pivot.
Position limiting structure of the present invention can play and prevent to get loose, limit footstock around the rotational and the effect of bearing uplift resistance, have good load-carrying properties, its ball pivot part when playing the resistance to plucking effect can be rotated by trace, contact with steel point for steel between steel ball and the concave ball shape footstock, whole micro-rotating process is actually rolling, restraint forces is less when therefore rotating, because stiffener is strengthened be connected with the steel ball stressed weakness at position of rod iron, the resistance to compression bearing capacity of bearing also strengthens thereupon; In addition, whole node of the present invention does not have concave surface, has avoided dust stratification, ponding problem, thus bearing in use its rotating property can not be affected, prolonged the application life of bearing; Support node profile of the present invention is small and exquisite attractive in appearance, has good architectural effect, can not destroy building integral design aesthetic feeling.
