Description
Technical field
The utility model is related to construction engineering technical fields more particularly to a kind of anti-float anchor rod to carry body device, more specifically
Ground is said, is to be related to a kind of anti-float anchor rod body of rod that is used for connect fixation, centering, the integrated synthesis device for strengthening bearing capacity.
Background technology
Traditional 2~4 reinforcing bar bodies of rod of the anti-float anchor rod body of rod generally have following several simply and easy treat modes when making,
First, simple concatenation, 2~4 reinforcing bars (specification is generally Φ 22, Φ 25, Φ 28, Φ 32) progress is simply closely spelled side by side
It connects, centering stent is set every 1.0m~2.0m, centering stent is uniformly distributed 3 using Φ 6 or Φ 8 or 10 reinforcing bars of Φ into circumferential
Or 4 stents take the mode of welding to be welded on the anchor pole main reinforcement body of rod, play reinforcing bar body of rod limitation being centered in anchor hole
The reinforcing bar body of rod is carried out built-up welding welding by intermediate effect, welding position together simultaneously, and this way is body of rod concentration and injecting cement paste
Contact surface is small, and bond stress is affected；Second is that some designing institutees are using the reinforcing bar of Φ 25 or so or the galvanized pipe of Φ 30 or so
Long 80~100 are set every 1.0m~2.0m, and the reinforcing bar body of rod is welded on into even circumferential distribution on galvanized pipe, plays connection
Fixed function.Than first way outline it is excellent, each reinforcing bar body of rod is slightly had into distance, it is wide with slip casting contact level, bond stress will
Slightly excellent, centering stent set-up mode is identical with first way.
Both forms are widely used in engineering, because it is only interpreted as the fixed dress of a connection by simple and mechanical
It puts, working mechanism is：The body of rod can be casted anchor work by the completion that is welded together, stent, which plays, positions the body of rod
Effect among anchor hole due to the engineering custom for not being taken seriously and following the beaten track, still largely uses in engineering so far.
This traditional handicraft has several weakness, first, field fabrication quality randomness is big, operating worker is often because only auxiliary
Help fixing device, carelessness construction in lifting desoldering occurs and come off that engineering safety accident is caused to happen occasionally；Secondly, welding capacity
Greatly, efficiency is low, cumbersome, takes time and effort；If thirdly, welding the unqualified damage to the reinforcing bar body of rod of worker's welding technique；It four：
Construction method is original, with after social progress construction quality improve, construction become more meticulous, rapid, procedure, modernization requirement not
It is adapted.
Utility model content
The purpose of this utility model is to propose a kind of both economical, quick construction, and quality assurance is easily operated, and can show
It writes and improves the anti-float anchor rod carrying body device for playing anchor pole efficiency, i.e., finished product prefabricated components device is, it can be achieved that directly fast at the scene
Speed installation, replaces traditional site welding to make centering stent, is welded and fixed the mode of anchor rod body.
Realize that the technical solution of above-mentioned purpose includes main points are constructed as below：
(1) material that using engineering plastics or metal material etc. has some strength carries out casting the anti-float anchor rod for raw material
Body device is carried, which, which must satisfy to be unlikely to damage when connection is fixed to be lifted, comes off, when anchor pole plays uplift effect
With the reinforcement body of rod and injecting cement paste bond stress, the effect of bearing capacity；
(2) the anti-float anchor rod reinforcing bar body of rod is carried body device by anti-float anchor rod when anchor pole assembling makes to carry out tightening lock
It is fixed, simple to operation, reliable in quality；
(3) it is equipped in the garter spring of anti-float anchor rod carrying body device and matches what is be engaged with the rib of the anti-float anchor rod reinforcing bar body of rod
Tongue and groove plays the effect for strengthening anti-float anchor rod reinforcing bar body of rod bond stress and bearing capacity after tightening；
(4) anti-float anchor rod carrying body device is equipped with centralising device, does not need to separately set centralising device again；
(5) anti-float anchor rod carrying body device arranges that the spacing can be 1.0m~2.0m at a certain distance.
The utility model uses above-mentioned technical proposal, and beneficial technique effect and advantage are：
This anti-float anchor rod is taken to carry body device, cumbersome connecting welding when traditional anchor pole makes can be substituted, it is right
The welding of middle stent, environment-friendly high-efficiency, Quality advance overcome the shortcomings of conventional construction method：
First, it is big to overcome field fabrication quality randomness, avoids and be susceptible to desoldering in lifting and lead to engineering safety
The generation of accident；
Second is that solving, welding capacity is big, and efficiency is low, cumbersome, the drawbacks of taking time and effort, high-efficiency environment friendly；
Third, improving anchor pole production quality, the unqualified damage to the reinforcing bar body of rod of worker's welding technique being welded with is avoided
Wound；
Fourth, improving rockbolt stress mechanism, which (relies on reinforcing bar to consolidate with cement mortar by common tension type anchor pole
The bonding of body bonds) becoming tension and compression composite anchor-rod, (transmission of power does not only rely on steel between anchor pole reinforcing bar and cement mortar induration
The bonding of muscle and cement mortar induration can also rely on the multiple anti-float anchor rods being distributed on reinforcing bar carrying body device to consolidate cement mortar
The pressure of knot body realizes that the stress distribution of cement mortar induration is improved, and avoids common tension type bolt cement slurry
The defects of induration tensile stress is easy to crack greatly can significantly improve anchor rod body elastoresistance and plastic deformation, so as to which more preferably protection is built
(structure) builds object；
Fifth, can with factory's mass production, accomplished anchor rod body making become more meticulous, be rapid, procedure, modernization.
