Description
Technical field
The present invention relates to the field of components of science of bridge building support more particularly to a kind of ball-type tension bridle irons and polygonal
Spend the method for distractive load.
Background technique
Support is the important component for being connected top girder construction and lower part pillarwork in science of bridge building, and basic function is
The upper load of structure is transmitted in substructure by support, while guaranteeing the need of stress required by structure and displacement
It wants.Therefore, under normal circumstances, it is desirable that have vertical bearing capacity, horizontal bearing or placement property in susceptor design.In most of feelings
Under condition, support, which has above functions, can meet the needs of engineering design.But in certain occasions, the individual fulcrums of structure can go out
Existing pulling force, and will lead to foundation settlement due to geology or construction etc., the requirement of anti-pulling can be proposed to support at this time.
Currently, the support of most of engineer application can only bear horizontal force and pressure, the pulling force of vertical direction cannot be produced
Raw effect.In recent years, it is the tension functional requirement for coping with bridge superstructure, produces some mode tensile supporting seats successively.These are anti-
Drawing support is succeeded application in the projects such as some sciences of bridge building, especially steel box girder bridge, cable-stayed bridge and suspension bridge, is obtained
Good effect.But meanwhile part tensile type support structure design and calculating in terms of existing defects, such as support up-down structure
When generating tension function, two contact surfaces are line contact or point contact, extreme case larger particularly with vertical pulling capacity
Under (such as earthquake) support corner exceed design angle when, it is easy to stress concentration phenomenon can be generated；On the other hand, a part of tension
Although support solves the problems in stress collection, but structure design is complex, and components cooperation is more, and support volume is huge
Greatly, weight is higher, and it is big to promote and apply difficulty in engineering actual items.
Summary of the invention
The purpose of invention: in order to provide a kind of effect preferably a kind of ball-type tension bridle iron and multi-angle distractive load
Method, specific purposes see specific implementation part multiple substantial technological effects.
In order to reach purpose as above, the present invention is adopted the following technical scheme that:
A kind of ball-type tension bridle iron, which is characterized in that support include can be fixedly connected with beam body upper bracket plate 1, can

The center of spherical of hat 3 lower face of liner plate is overlapped with the cambered surface center of arc pressuring plate 4.
The further technical solution of the present invention is that the arc pressuring plate 4 passes through bolt and the upper bracket
The flange lower face of plate 1 is fixed.
The further technical solution of the present invention is, is provided on the plane upper face of the spherical crown liner plate 3 and guide rail bar
The groove matched；1 inner plate surface of upper bracket plate is also provided with the groove matched with guide rail bar；The guide rail bar 2
One end is matched with the groove of 1 inner plate surface of upper bracket plate, and the other end is matched with the plane upper face groove of spherical crown liner plate 3；It should
Guide rail bar is protrusion.
The further technical solution of the present invention is, in the plane of the 1 plane inner plate surface of upper bracket plate and spherical crown liner plate 3
Directly cooperate between the ball impression shape upper face of plate face, the ball-type lower face of spherical crown liner plate 3 and lower support plate 5 or by having
The slide plate or stainless steel plate of respective shapes cooperate.
The further technical solution of the present invention is that 1 top of upper bracket plate is connected by fixed above upper bolt-nut
Then the entire entirety of beam body.
The further technical solution of the present invention is that 5 lower section of lower support plate is mounted on down by lower anchor bolt 14
In sleeve, described lower sleeve a part is located in pier, and a part is located in pinner, also includes to be connected to pier and pinner
Spiral bar 18.
A kind of method of the multi-angle distractive load of ball-type tension bridle iron, which is characterized in that described in any one as above
Production, comprise the following steps,
When generating pulling force up and down, intermediate guide-rail structure is that protrusion has certain positioning action, avoids big displacement
The offset of amount, the circle of arc plate structure, that is, upper bracket plate 1 one at both ends enclose arc-shaped upper face comprising that can surround 5 top one of lower support plate
Arc pressuring plate 4 and upper section 52 one circle arc-shaped upper face cooperation, belong to one week stress disperse, make structure stress stabilization can
It leans on, avoids the generation of stress concentration phenomenon.
The further technical solution of the present invention is, is that arc cooperates above the lower support plate 5 of spherical crown liner plate 3 and lower section,
In addition to upper and lower load, when there is horizontal load stress, the structure of arc makes it have certain cushion space, will not
