Description
Technical field
The present invention relates to a kind of anchor, especially a kind of "-" type end applied to assembled external prestressing is anchored
Device belongs to technical field of structural engineering.
Background technique
It is manufacture of steel structure simplicity, construction is simple, cheap, the life of people is more and more come into its unique advantage
It is living, almost they big figure can be seen in each corner.On the other hand with society development and economic level raising,
Demand of the people to steel mechanism is also increasing, there is an urgent need to the girder steel of more large span, bigger workshop, however part steel construction
Structural elements Lack of support caused by the presence of increasing because of the dead load or deformation of member is larger is unsatisfactory for asking using functional requirement etc.
Topic.
Tradition, which is reinforced, reinforces steel construction with the method for enhancing bonding strength using increasing original structure member section, needs to stop first
Only internal normal activity, and a large amount of support scaffolding manufacture workbenches are set up, construction quality can not also accomplish effectively to protect
Barrier, and such method also has a certain amount of welding and installment work, causes centainly to damage to original structure.In addition, answering in advance in vitro
The application technical requirements of power are higher brought to construction it is constant.
Summary of the invention
For the above-mentioned deficiency for solving the prior art, the invention proposes an a kind of words applied to assembled external prestressing
Type end anchor, the assembled device are used for the tip node connection during strengthening of steel bridge, can effectively solve to connect because of welding steel
Influence of the fitting to raw steel component, and can constructing in normal activity, construction method is simple, and can be with
The effectively reduction strengthening construction period.
In order to solve the above technical problems, the technical solution used in the present invention is:
A kind of "-" type end anchor applied to assembled external prestressing, the "-" type end anchor mainly wrap
Include rubbing device module, "-" type construction part module and anchoring assembly module；
The rubbing device module includes upper triangle rubbing device and lower triangle rubbing device, upper triangle friction
Device and lower triangle rubbing device are respectively arranged on the downside of steel I-beam top flange and on the upside of steel I-beam lower flange, and are risen
To the effect frictionally secured；
The "-" type construction part module includes "-" type component, upper strut and lower supporting rod, and "-" type construction part module passes through
Upper strut and upper triangle rubbing device are connected and fixed on steel I-beam top flange, and are filled by lower supporting rod and the friction of lower triangle
It sets and is connected and fixed on steel I-beam lower flange；It is provided on the upper triangle rubbing device and lower triangle rubbing device
Pre-manufactured hole, the upper strut and lower supporting rod pass through the pre-manufactured hole；Fixed link, fixed link are equipped on the "-" type component
Abutted respectively with upper triangle rubbing device and lower triangle rubbing device, play prevent triangle rubbing device and under
The inclined effect of triangle rubbing device；
The anchoring assembly module includes anchor and tightening latch, and anchor is fixed on "-" type structure by tightening latch
Part lower position；Steel strand wires pass through anchor, and are anchored by anchorage.
Further, the anchor is connect by two or more tightening latches with "-" type member lower, can be according to existing
The position that field situation selection adapts to is connect with anchor by tightening latch.
Further, the upper triangle rubbing device and lower triangle rubbing device are a pair, are respectively symmetrically set
It is placed in steel I-beam web two sides, cross section is respectively T-type and inverted T shaped, and on the downside of top flange and steel I-beam
Blasting treatment is done at the upper contact of lower flange with increasing friction force.
Further, the upper triangle rubbing device and lower triangle rubbing device is relatively oblique is arranged in a staggered manner.
Further, the tightening latch and fixed link are bolted with "-" type component.
A kind of installation method of above-mentioned "-" type end anchor applied to assembled external prestressing:
Firstly, two good upper triangle rubbing devices of pre-production are placed in symmetrical position on the downside of steel I-beam top flange
It sets, it is ensured that upper triangle rubbing device abuts steel I-beam web, and lower triangle rubbing device is placed in steel I-beam lower flange
Upside is relative to the upper slightly backward position of triangle rubbing device；
Secondly, installing "-" type component and being fixed by upper strut and lower supporting rod, anchor is finally installed；
Again, fixed link is installed, "-" type component and upper triangle rubbing device and lower triangle rubbing device are adjusted
Distance, it is ensured that the two is parallel；
Finally, and be fixed by anchorage, and apply certain prestressing force in use, steel strand wires pass through anchor,
It realizes self-locking.
Under static(al) state, "-" type component, lower triangle rubbing device and upper triangle rubbing device form a thick stick
Bar, lower triangle rubbing device are fulcrum.On vertical direction, the component of the gravity G of "-" type end anchor in vertical direction
Point of the power downward to "-" type component and lower triangle rubbing device to "-" type component upwards with upper triangle rubbing device
Power keeps balancing in Y direction；In horizontal direction, the gravity G component in the horizontal direction and girder steel of "-" type end anchor
Upper triangle rubbing device and lower triangle rubbing device frictional force are kept balancing in X-direction.Whole device is against self weight
It realizes and self-locking reaches balance.
Under pre-stressed state, the component and I-shaped of the gravity G of prestressing force F and "-" type end anchor in vertical direction
Girder steel keeps balance in the component of Y direction to upper triangle rubbing device and lower triangle rubbing device frictional force；Level side
Upwards, the gravity G component in the horizontal direction and steel I-beam of prestressing force F and "-" type end anchor are to upper triangle friction
Device and lower triangle rubbing device frictional force keep balancing in the component of X-direction, and whole device realization is self-locking to reach balance.
Upper triangle rubbing device, lower triangular form rubbing device, "-" type type component in the anchor of "-" type end and
Anchor is completed according to design in factory process, and site machinery assembly is completed.It needs to be faced before not applying prestressing force
When anchor.
Upper triangle rubbing device is to uniform by upper triangle rubbing device to the pressure on the downside of steel I-beam top flange
Be applied under steel I-beam top flange and survey, effectively prevent stress concentration.
Lower triangle rubbing device is to uniform by lower triangle rubbing device to the pressure on the upside of steel I-beam lower flange
Be applied on steel I-beam lower flange and survey, effectively prevent stress concentration.
The device can effectively solve the influence because of welding steel fastener to raw steel component, can be in normal activity
It constructs, construction method is simple, can effectively reduce the strengthening construction period.
Compared with the existing technology, the present invention has the following technical effect that
This kind of "-" type end anchor is safely and effectively, to examine from actual experiment.The device is by steel I-beam
The concentrated stress that tip node connects in reinforcing process passes through upper triangle rubbing device, the lower ingenious uniform conversion of triangle rubbing device
Lower flange on to girder steel effectively prevents the concentration of stress, and whole process has evaded traditional welding to original using mechanical assembly
Structured damage.The tip node anchor whole design is brief, clear and cheap by power path, can use extensively
The connection of tip node in strengthening of steel bridge.
