Abstract
The utility model provides a recycled prestress anchor rod, and belongs to the technical field of buildings. The recycled prestress anchor rod solves the problem of the existing prestress anchor rod that an anchoring body and an anchoring section are of an integral structure, so the anchoring section cannot be recycled after the project is finished. The recycled prestress anchor rod comprises a tubular rod body, wherein both ends of the tubular rod body are penetrated through, the tubular body is of a two-section structure, namely a fixing section and a recycled recycling section, the fixing section is fixedly connected with a concrete base in an anchoring hole, the outer end of the recycling section is detachably connected with a steel channel at the outer side of the anchor hole, the fixing section and the recycling section are abutted through threads, and the outer side of the recycling section is sheathed with a sleeve tube so as to separate the recycling section from the concrete base. The recycled prestress anchor rod has the advantage that the recycling section can be detached and recycled after anchoring, and the loss of construction resources is greatly reduced.
Description
Technical field
The utility model belongs to technical field of buildings, relates to a kind of recoverable prestressed anchor pole.
Background technology
Prestressed anchor is the device of the prestress anchoraging for being slided in Rock And Soil slope, and prestress anchoraging is with anchoring process, to increase a kind of measure of retaining structure or stability of rock-soil body.Its method is that drilling passes likely slide plane that slide or that slided, one end of reinforcing bar (or cable wire) is fixed in the stable Rock And Soil at the bottom of hole, again reinforcing bar (or cable wire) is strained so that can be produced certain screen resilience (being prestressing force), then the other end of reinforcing bar (rope) is fixed on to Rock And Soil or retaining structure surface, utilizing the screen resilience of reinforcing bar to compress can slidable Rock And Soil or retaining structure, to increase the shear strength on slide plane, thereby reach the object that improves Rock And Soil or retaining structure stability.
Traditional prestressed anchor comprises anchor head, anchor bundle body and anchoring section.Anchor head is the member for stretch-draw and locking, comprises outer anchor head and backing plate etc.Anchor bundle body is the member that links inside and outside anchor head and bear stretching force.Anchoring section is mounted in anchor hole bottom, and its effect is to provide anchored force for stretch-draw anchor.After anchoring section is fixing, by the stretch-draw of jack pair anchor bundle body, thereby basement rock or building are applied to compressive pre-stress, reach the object of reinforcing or improving its stress condition.Existing prestressed anchor anchor bundle body and anchoring section mostly are integrative-structure, insert fixing in the anchor hole of Rock And Soil after, anchor bundle body just can not reclaim, so the mode of operation of this device has just formed the huge wasting of resources.
Summary of the invention
The purpose of this utility model is that anchor bundle body and the anchoring section for existing prestressed anchor is structure as a whole, thereby after using, anchor bundle body can not reclaim the problem that forms huge waste, has proposed the recoverable prestressed anchor pole of a kind of two-part.
The purpose of this utility model can realize by following technical proposal: a kind of recoverable prestressed anchor pole, it is characterized in that, it comprises the tubulose body of rod that runs through two, the body of rod is dual segment structure, be divided into canned paragraph and callable exhausting section, described canned paragraph and the concrete pedestal in anchor hole are connected, and the channel-section steel in exhausting section outer end and anchor hole outside removably connects, screw thread docking between described canned paragraph and exhausting section, described exhausting section outside cover has sleeve pipe so that exhausting section and concrete pedestal are separated.
In above-mentioned a kind of recoverable prestressed anchor pole, described sleeve pipe is pvc sleeve pipe.
In above-mentioned a kind of recoverable prestressed anchor pole, between described canned paragraph and exhausting section, by a sleeve, achieve a butt joint, canned paragraph and exhausting section are threaded in respectively the two ends of sleeve.
Compared with prior art, this device can reclaim exhausting section dismounting after anchoring, has reduced greatly the consumption of working sources.During dismounting, in outer end, rotate back to receipts section and can make exhausting section and canned paragraph realize partition, simple to operate, convenient.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
In figure, 1, rock-soil layer; 2, anchor hole; 3, concrete pedestal; 4, canned paragraph; 5, sleeve; 6, slip casting through hole; 7, exhausting section; 8, sleeve pipe; 9, inclined-plane, rock stratum; 10, nut; 11, channel-section steel.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
The utility model is for fixing slope slip rock-soil layer 1, as shown in Figure 1, this recoverable prestressed anchor pole comprises the body of rod, body of rod hollow, there is the slip casting through hole 6 that runs through two, the described body of rod is dual segment structure, is divided into canned paragraph 4 and callable exhausting section 7, and exhausting section 7 outside covers have pvc sleeve pipe 8 so that exhausting section 7 and concrete pedestal 3 are separated.
In the present embodiment, between canned paragraph 4 and exhausting section 7, by sleeve 5, dock, canned paragraph 4 and exhausting section 7 are threaded in respectively the two ends of sleeve 5.In addition, also directly screw thread docking between canned paragraph 4 and exhausting section 7.
During construction, on rock-soil layer 1 slope, inwardly offer an anchor hole 2, insertion anchor pole, Grouting Pipe extends anchor hole 2 bottoms through slip casting through hole 6, injects slurry, and slurry envelopes canned paragraph 4 and sleeve pipe 8, and the hard solid concrete pedestal 3 that later forms, makes it fix canned paragraph 4.Next, with the outside stretch-draw exhausting section 7 of jack in order to rock-soil layer 1 is applied to prestressing force, the inclined-plane, rock stratum 9 that then channel-section steel 11 linked closely, the outer end of exhausting section 7 is connected by nut 10 and channel-section steel 11, finally unclasps the locking that realizes anchor pole after jack.Because exhausting section 7 outside covers have pvc sleeve pipe 8, therefore unfixing with concrete pedestal 3, after construction is complete, exhausting section 7 and canned paragraph 4 dismountings can be used for next construction, which reduces construction cost greatly, has reduced the consumption of working sources.
Should be appreciated that, in claims of the present utility model, manual, all " comprising ... " is all interpreted as open implication, and namely its implication is equal to " at least containing ... ", and should not be construed as enclosed implication, its implication should not be construed " only comprising ... ".
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
