Description
Technical field
Concretely it is the cable testing bridge with function of seismic resistance the present invention relates to support meanss.
Background technology
Cable testing bridge is divided into the structures such as slot type, pellet type and ladder-type, grid type, by support, trailing arm and installation annex etc.
Composition.Crane span structure can independently set up in building, it is also possible to be attached on various buildings or structures and piping lane support, should embody
Simple structure, handsome in appearance, flexible configuration and it is easy to maintenance the features such as, whole parts are both needed to carry out zinc-plated treatment, installed in building
Build the outdoor crane span structure of beyond the region of objective existence.
At present, it is bolted by the way of more piece more than cable testing bridge, when cable testing bridge runs into seismology or wind
During situation of shaking, vibration can make bolt produce loosening, also can produce a certain degree of damage to cable testing bridge, reduce cable testing bridge
Service life.
Publication number 205877423U, a kind of Metro Cable crane span structure suspension and support of antidetonation, including lower bottom, upper bottom and spiral shell
Hole, the lower bottom is fixedly connected by damper with bearing, and tube seat is provided with above the bearing, and the lower bottom is consolidated with peg
Fixed connection, the peg is fixedly connected by screw rod with pole, and the pole is fixedly connected by base with structure outer, described
At least provided with a group expansion bolt on base.The patent can bring certain anti seismic efficiency, but set such as the patent working mode
In damper, so need it is a large amount of set, and install that very portion is convenient, economic benefit is also not good enough.
The content of the invention
The present invention in view of the shortcomings of the prior art, the invention provides the cable testing bridge with function of seismic resistance.
The present invention solves above-mentioned technical problem, and the technical scheme of use is, the cable testing bridge with function of seismic resistance, if including
The crane span structure unit of dry slot type and the antidetonation connector for connecting adjacent crane span structure unit；General cable testing bridge often saves crane span structure unit and leads to
Cross bolt connection, the present invention by setting antidetonation connector between adjacent crane span structure unit, to the work of cable testing bridge when making vibration
Concentrated on energy and discharged on antidetonation connector, it is ensured that the safety of cable testing bridge.
The front end of the crane span structure unit is provided with the flange extended along the crane span structure unit cell body direction, and rear end is provided with edge should
The groove of crane span structure unit cell body direction depression；The antidetonation connector includes that shape is similar from inside to outside and the interior U that is stacked
Shape plate, middle U-board and outer U-board, pass through viscoelastic material between the interior U-board and middle U-board, middle U-board and outer U-board
Bonding；The interior U-board and middle U-board, middle U-board all include adhesive portion with outer U-board and from the adhesive portion along interior U-board or
In middle U-board or outer U-board length direction forwards, backwards two ends extend extension, the extension of rear and front end with it is relative
Crane span structure unit is connected.
The adhesive portion of the middle U-board is Nian Jie with interior U-board and outer U-board and is clamped by the interior U-board and outer U-board,
Extending part of U-board is connected in groove and with crane span structure unit in this, and the extension of the interior U-board and outer U-board prolongs
Stretch direction opposite with the extension bearing of trend of middle U-board；The extension of the interior U-board and outer U-board will be relative another
Individual crane span structure unit flange is held between interior U-board and outer U-board, and the extension of interior U-board and outer U-board is relative with described
The flange connection of another crane span structure unit.
It is connected with the extension of antidetonation connector by setting the flange and groove, the energy of vibration is connected by antidetonation
The adhesive portion of fitting absorbs, release, twisting interior U-board, middle U-board and outer U-board, the viscoplasticity of adhesive portion when specifically vibrating
The all directions power that material is subject to, by the material properties of viscoelastic material itself, heat energy is converted into by mechanical energy, is so just given
Cable testing bridge brings preferable damping effect.
It is further to leave gap, the adhesive portion and flange between the extension and groove bottom land of the middle U-board
Between leave gap.
By setting gap, when cable testing bridge is received the active force along the crane span structure direction, antidetonation connector can be played
Certain damping effect, flange and groove will not interfere with the damping work of antidetonation connector.
It is further that flexible inserts is filled in the gap.
By filling elastic inserts in the gap, further damping effect can be played, particularly work as cable bridge
When frame receives the active force along the crane span structure direction, the service life for aiding in cushioning effect to extend antidetonation connector simultaneously is also functioned to.
Be further, the antidetonation connector also include upper lid, it is described it is upper lid be located at outer U-board upper end and with the outer U
Shape plate upper end is adapted to.
Covered by setting, make cable closure after cable testing bridge, it is necessary to when repairing, can be more quick and easy.
It is further that the upper lid lower surface is provided with rubber blanket.
By setting rubber blanket, the cushioning effect after being contacted with antidetonation connector is played.
It is further that the outer U-board both sides are provided with boss, and boss upper end is connect by spring with the top cap.
After the spring connects with top cap, make cable testing bridge in vibration, upper lid will not be because of the cable testing bridge that shaken
The shock of upper lid and crane span structure and antidetonation connector can also be mitigated simultaneously.
It is further that the interior U-board, middle U-board and outer U-board all include base plate and two side plates, described two
Side plate passes through latex or adhering with epoxy resin.
Three plate bodys of flexible splicing successively so are set to by by interior U-board, middle U-board and outer U-board, this can be made
Cable testing bridge can have more preferable wilfulness, reduce the deformation probability of cable testing bridge.
Beneficial effects of the present invention：Cable testing bridge with function of seismic resistance of the present invention is by the antidetonation described in setting
Connector, enables cable testing bridge to concentrate on release on antidetonation connector to the effect energy of cable testing bridge when vibration is received, and protects
The safety of cable testing bridge is demonstrate,proved, compared to other cable testing bridges, cable testing bridge of the invention possesses more preferable pliability, can make crane span structure
The loosening probability of connecting bolt between crane span structure unit relative can be twisted and reduced between unit.
