A kind of presstressed reinforcing steel sealing off and covering anchorage device, including being embedded in prefabricated components and with the steel strand wires on magnetic work anchor and work anchor for connection, it is characterized by: the main body of the sealing off and covering anchorage device is round tube, the same end of the round tube is equipped with strong magnet ring and sealing rubber ring, the outside of round tube is arranged in the strong magnet ring, the inside of round tube is arranged in the sealing rubber ring, the other end of the round tube is equipped with air hole, the air hole is equipped with extension, is equipped with sealing cover with air hole the same end in the round tube.Novel sealing off and covering anchorage device is not necessarily to remaining auxiliary material, can be used alone, and can play the role of saving the time, improve work efficiency.And its sealing performance is high, and controllability is strong, and operates simple.Meanwhile because its locking member can be dismantled, novel sealing off and covering anchorage device can realize duplicate recycle.
Description
Technical field
The utility model relates to a kind of presstressed reinforcing steel sealing off and covering anchorage devices, and in particular to the prestressing force before being related to inherent stress mud-jacking technique
The protection of muscle sealing off and covering anchorage.
Background technique
By taking precast prestressed small box girder as an example, traditional anchor sealing is completed in prestressed stretch-draw operation and cuts off outer body steel to twist
Working instrument anchor is lived using PE pipe sleeve after line, then is filled by artificial mixing cement slurry and carries out sealing off and covering anchorage operation.Reach to cement sealing off and covering anchorage
Pumping of prostressed duct is carried out after some strength again, seriously constrains live mud jacking efficiency.Before beam body blocks operation, still need to cut
Cement sealing off and covering anchorage position, is blocked with reinforced concretes such as beam bodies.So traditional handicraft has the disadvantages that the later period of sealing off and covering anchorage needs
It cuts, it is serious to cause waste, and need to just can be carried out inherent stress mud-jacking construction operation after cement slurry sealing off and covering anchorage body reaches some strength,
Required time is longer, and the use of cement sealing off and covering anchorage is disposable operation, the work that the newer sealing off and covering anchorage device of traditional handicraft process uses
Sequence is complicated, and sealing off and covering anchorage leakiness, suitable spillage, whitewashing, and sealing off and covering anchorage sealing is difficult to control.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides that a kind of sealing performance is high, controllability is strong and operation letter
Easy presstressed reinforcing steel sealing off and covering anchorage device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of presstressed reinforcing steel sealing off and covering anchorage device, including be embedded in prefabricated components and on magnetic work anchor and work anchor
Steel strand wires for connection, it is characterised in that: the main body of the sealing off and covering anchorage device is round tube, and the same end of the round tube is equipped with strong magnetic
The outside of round tube is arranged in ring and sealing rubber ring, the strong magnet ring, and the inside of round tube, the round tube is arranged in the sealing rubber ring
The other end be equipped with air hole, the air hole is equipped with extension, in the sealing off and covering anchorage device main body and on air hole the same end
Equipped with sealing cover.
In the utility model, the constituent material of the round tube is ferritic stainless steel.
In the utility model, the development length of the extension is 5mm ~ 100mm.
In the utility model, the sealing cover is equipped with lift-pull handle, and the lift-pull handle is arc-shaped.
In the utility model, the strong magnet ring is neodymium iron boron.
In the utility model, the round tube is provided on one end of strong magnet ring and is additionally provided with the bolt for preventing strong magnet ring from falling off
Hole.
The beneficial effects of the utility model are: novel sealing off and covering anchorage device is not necessarily to remaining auxiliary material, it can be used alone, section can be played
It makes an appointment, improve the effect of work efficiency.And its sealing performance is high, and controllability is strong, and operates simple.Meanwhile because its lock
Tight component can be dismantled, so novel sealing off and covering anchorage device can realize duplicate recycle.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；
Fig. 2 is the scheme of installation of the present embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to Fig.1, Fig. 2, a kind of presstressed reinforcing steel sealing off and covering anchorage device, including the work anchor 2 being embedded in prefabricated components 1 and work
Steel strand wires 3 on anchor 2 for connection, the main body of the sealing off and covering anchorage device are the round tube 4 that ferritic stainless steel is constituted.Round tube 4 it is same
End is equipped with strong magnet ring 5 and sealing rubber ring 6, and the outside of round tube 4 is arranged in strong magnet ring 5, and sealing rubber ring 6 is arranged in round tube 4
Portion does not fall to achieve the best use effect and prevent sealing off and covering anchorage device from can consolidate in work anchor 2, and strong magnet ring 5 is that have
The neodymium iron boron of the title of magnetic king.And at least three are additionally provided on one end that round tube 4 is provided with strong magnet ring 5 prevents strong magnet ring 5 de-
The bolt hole fallen.The other end of round tube 4 is equipped with air hole 7, and air hole 7 is equipped with extension, and extension prolongs
Elongation is 5mm ~ 100mm.Meanwhile in round tube 4 with the position of 7 the same end of air hole is outside upper is additionally provided with for sealing round tube 4
Sealing cover 8, the lift-pull handle 9 of arc-shaped is equipped on sealing cover 8, removes sealing off and covering anchorage device after convenient to use.
When the utility model is used, it first gets out the work anchor 2 being embedded in prefabricated components 1 and is used on work anchor 2
The steel strand wires 3 of connection, after first high-strength magnet ring 5 is inserted on round tube 4 by unencapsulated one end and by bolt hole to be screwed into bolt steady
Gu the round tube 4 of mounted each components is passed through high-strength magnet ring then by the installation of sealing rubber ring 6 to the unsealing end of round tube 4
5 are anchored on the tool of work anchor 2.Grouting material is by flowing to sealing off and covering anchorage outside presstressed reinforcing steel and work clip sheet gap during inherent stress mud-jacking
In device, to grouting material from sealing off and covering anchorage device air hole 7 outflow show that pipeline pneumatic mortar has been expired, after take out high-strength magnet ring 5, further take out steel
Body and sealing rubber ring 6 are cleaned.
Above description is merely a prefered embodiment of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
