Abstract
The invention discloses a novel cast-steel spherical hinge support, which comprises a base fixedly connected with a column-shaped supporting body with the top being an evagination crown body which is embedded in a provided groove on the lower end surface of a rolling body, the shape of the inner surface of the provided groove corresponds to that of the evagination crown body, the inner side wall of the provided groove is connected with a baffle ring in a screw way, and the baffle ring is arranged outside the column at the lower part of the evagination crown body. The support can not only meet the rolling demands of the nodes, but also can bear horizontal force and the vertical pull force as well as pressure, thus being mainly used for large-span space structure bearing complicated forces and heavy shaped steel structure.
Description
Technical field
The present invention relates to a kind of steel work bearing, specifically, is a kind of cast steel ball hinged support that is applicable to labyrinth.
Background technology
Existing " Code for design of steel structures " (GB50017-2003) the middle steel work bearing of recommending to use mainly is divided into plate bearing, curved support, roller support, hinge support, spherical bearing etc. according to its form of structure, and these several bearings mainly are applicable to stressed fairly simple, not high to bearing deformation requirements steel work.For example, plate bearing and curved support only are applicable to the steel work that is subjected to pulling force or pressure that span is less, and the ball pivot pressure supporting seat can only rotate can not translation, and fixedly hinge support can only rotate and can not take place to move perpendicular to hinge any etc. around hinge axes.At present, the rotation of also not satisfying support node in the engineering simultaneously requires and resists the bearing that horizontal force and vertical pressure require, and can't satisfy the large-span space structure of some stressed complexity in the engineering practice and the demand of Heavy Type Steel Structure.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of novel cast steel ball hinged support node that is applicable to labyrinth, and it can solve existing steel structure node commonly used can not satisfy the shortcoming of rotating requirement and opposing horizontal force and vertical pressure requirement simultaneously.
In order to solve the problems of the technologies described above, the present invention is achieved by following technical scheme:
A kind of cast steel ball hinged support, comprise base, being connected with the top on the described base is the cylindrical support body of evagination hat body, described evagination hat body is flush-mounted in the preformed groove of rotor lower surface, the shape of described preformed groove inner surface is corresponding with described evagination hat body, be bolted with baffle ring on the inside wall of described preformed groove, described baffle ring is arranged at the cylinder outside of described evagination hat body bottom.
Described evagination hat body is a kind of among ball-crown body, cylinder, round platform, the circular cone.
The inner surface of described rotor preformed groove is made up of spherical crown surface and cylindrical side wall.
Connect for chamfering between described spherical crown surface and the cylindrical side wall.
The spherical diameter of described evagination hat body is less than the spherical diameter 100mm of rotor preformed groove inner surface.
Leave the gap of 10mm between the soffit of described evagination hat body and the upper surface of baffle ring.
The invention has the beneficial effects as follows:
When being under pressure, bearing transmits pressure by the contact surface between rotor and the cylindrical support body top evagination hat body, transmit pulling force by the contact surface between cylindrical support body top evagination hat body and the baffle ring when being subjected to pulling force, contact sphere and cylindrical lateral surface by the cylindrical support body when being subjected to horizontal force are transmitted horizontal force.Like this, bearing of the present invention can satisfy the rotation requirement of node, can bear horizontal force and vertical pulling force and pressure simultaneously again, and force way is no longer single, can be mainly used in the large-span space structure and the Heavy Type Steel Structure of stressed complexity.
Description of drawings
Accompanying drawing is the structural representation of the specific embodiment of the invention.
Among the figure: rotor 1 cylindrical support body 2 bases 3 baffle rings 4
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
From accompanying drawing as can be seen, cast steel ball hinged support of the present invention is made up of four parts, be respectively rotor 1, have cylindrical support body 2, base 3 and the baffle ring 4 of ball-crown body, described four parts are all by casting, and material property and processing and fabricating must satisfy the requirement of existing China Engineering Construction Standardization Association standard " cast steel node tecnical regulations ".
The bottom surface radius of described cylindrical support body 2 top ball-crown bodies makes ball-crown body with respect to the cylinder evagination greater than the bottom surface radius of its underpart cylinder.The cylinder bottom of described cylindrical support body 2 is fixed on the base 3 by being threaded.Described rotor 1 lower surface is provided with a preformed groove, and described preformed groove is by forming with corresponding sphere of described ball-crown body and cylindrical side wall, and cylindrical side wall is provided with screw thread; Chamfering connects between spherical crown surface and the cylindrical side wall, has avoided the existence of wedge angle, guarantees the flexibility of rotating.Described baffle ring 4 is arranged at the cylinder outside of described ball-crown body bottom and is bolted on the inside wall of rotor 1 preformed groove.
The ball-crown body of described cylindrical support body 2 is flush-mounted in the inner surface and the formed space of baffle ring 4 upper surfaces of rotor 1 preformed groove, thereby forms rotating hinge.
For making the support node rotating function better, leave the gap of 10mm between the soffit of described cylindrical support body 2 ball-crown bodies and the upper surface of baffle ring 4, the spherical diameter of described cylindrical support body 2 ball-crown bodies is less than the spherical diameter 100mm of rotor 1 preformed groove inner surface.
When being under pressure, bearing transmits pressure by the contact surface between rotor 1 and the cylindrical support body 2 top evagination hat bodies, contact surface when being subjected to pulling force between cylindrical support body 2 top evagination hat bodies and the baffle ring 4 transmits pulling force, transmits horizontal force by the contact sphere and the cylindrical lateral surface of cylindrical support body 2.
