Description
Technical field
The present invention relates to the large corner swivel of a kind of strut termination welded plate type point apparatus, belong to design and the construction field of building Cable Structure in the civil engineering.
Background technology
Cable Structure is as the major structural types of prestressed steel structure, and at home and abroad building structure field is used widely.At present, building Cable Structure commonly used mainly contains tension string beam structure, suspended-dome structure, oblique pull network, cable dome structure, Cable Truss Structure, rope web frame etc. in engineering.In these structures, all can there be the hinged strut in end of pressurized.In some engineerings, for satisfying the requirement of operational phase, the strut termination require for can two in addition multiple-directional rotating.And in the construction stage, install for ease of members such as drag-lines, strut often also requires to be multiple-directional rotating significantly.Therefore, in these engineerings, need the ball pivot of strut termination for can significantly rotating.
Current, the joint form that the strut termination is commonly used is for having unidirectional hinged otic placode node and ball pivot cast steel node etc.Unidirectional hinged otic placode node is to use otic placode as connector, and the otic placode of strut and the member that links to each other is carried out pin joint with bearing pin.Unidirectional hinged otic placode node mainly can satisfy the large rotation angle on the bearing pin rotation direction, simple structure, and making and easy for installation, but on other direction, can only rely on the less gap between the otic placode to realize minor rotation.In some engineerings, because the strut termination needs multidirectional large corner to rotate, cause easily otic placode stuck, strut is difficult to freely swing, and strut is subject to extra moment of flexure, affects structural performance.
The ball pivot cast steel node is to produce cast steel base and cast steel bulb by casting technique, the inboard sphere of base and bulb outside sphere match, then cast steel bulb and cast steel base are welded with strut and adjacent members respectively, during installation the cast steel bulb is embedded in the cast steel base, again the anticreep cover plate is connected with bolt with the cast steel base, prevents that the cast steel bulb is deviate from the cast steel base under the fortuitous event.The ball pivot cast steel node can satisfy operational phase and the construction stage is two-way to strut even the rotation requirement of multidirectional large corner, but because the wood property of steel-casting and common iron is different, both welding require high to the solderability of steel-casting, the die cost of making in addition steel-casting is higher, so ball pivot cast steel node expense is high.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the invention provides the large corner swivel of a kind of strut termination welded plate type point apparatus, satisfy the two-way even any rotation requirement to large corner to strut of operational phase and construction stage, structural form is simple simultaneously, and expense is low.
For achieving the above object, the technical solution used in the present invention is:
The large corner swivel of strut termination welded plate type point apparatus comprises four-bladed vane base, upper head plate, anticreep cover plate, spheroid, lower four-bladed vane base and bottom plate; Described upper four-bladed vane base is fixedly connected with upper head plate, upper head plate detachably is fixedly connected with the anticreep cover plate, it is common that form and can avoid in the ball chamber that spheroid comes off that the part of described spheroid is embedded in four-bladed vane base, upper head plate and anticreep cover plate, the part that is exposed at outside the ball chamber is fixedly connected with lower four-bladed vane base, and lower four-bladed vane base is fixedly connected with bottom plate.
Said apparatus, when mounted, at first with sphere installation in the ball chamber that four-bladed vane base and upper head plate form, again anticreep cover plate and upper head plate are fixed, spheroid is limited in the ball chamber, lower four-bladed vane base and the bottom plate fixed with spheroid are positioned at outside the ball chamber.In this device, the function of its realization is identical with existing ball pivot cast steel node, satisfies the two-way even any rotation requirement to large corner to strut of operational phase and construction stage; Simultaneously four-bladed vane base, upper head plate, anticreep cover plate, lower four-bladed vane base and bottom plate all can adopt general steel plate to make, and the cost of production of parts is low, need not the specialized designs casting mould, and the installation between the different parts, convenient fixing.
More excellent scheme, the Plate Welding form that described upper four-bladed vane base adopts quadrature to place, the inboard that contacts with spheroid is the concave arc line, described circular arc line and spheroid lateral surface coupling.Spheroid contacts as main take line with upper four-bladed vane base during rotation, and rotation friction is little.
More excellent scheme, the trapezoidal Plate Welding form that described lower four-bladed vane base adopts quadrature to place, prevented that ball pivot from rotating at present four-bladed vane base and the collision of anticreep cover plate, the inboard that lower four-bladed vane base is fixedly connected with spheroid is the concave arc line, and the diameter of described concave arc line is consistent with sphere diameter.
More excellent scheme, the ring steel plate of perforate centered by the described upper head plate, the inboard that contacts with spheroid is interior concaved circular cambered surface, described concaved circular cambered surface and spheroid lateral surface coupling.
More excellent scheme, described anticreep cover plate pieces together the structure of center drilling by two curved plates, and the inboard that contacts with spheroid is interior concaved circular cambered surface, described concaved circular cambered surface and spheroid lateral surface coupling.The anticreep cover plate adopts the design of two-piece type amalgamation structure, can make things convenient for the installation of whole device.
More excellent scheme all is provided with bolt hole on described upper head plate and the anticreep cover plate, and is bolted, and bolt arrangement can be for convenience detach and be installed, and connects reliable.
More excellent scheme, described spheroid are medicine ball or welding hollowing ball; Can reduce the materials'use amount when using hollow ball, reduce the weight of whole device, but must design as required hollow ball, satisfy requirement of strength.
More excellent scheme, described bottom plate are plane steel plate, the convenient connection simple in structure.
Benefit of the present invention is: the large corner swivel of strut termination welded plate type point apparatus has been realized the two-way even any rotation to large corner of strut, while part simple structure, make easily processing, expense is low, and precision is high, and spheroid contacts as main take line with upper four-bladed vane base during rotation, rotation friction is little, only need during on-the-spot the installation spheroid is embedded upper cross-shaped base, then with bolt the anticreep cover plate is connected with upper head plate and gets final product, simple and convenient.
