Description
Technical field
The utility model relates to the foundation construction technology of a kind of building and structure, is used for the production and the site operation of pre-stress hollow pile tube, particularly a kind of no steel end plate pile tube.
Background technology
Pile for prestressed pipe has occupied the whole market of worker China Democratic National Construction Association pile foundation at present basically, and use has a large capacity and a wide range, and pile tube is generally formed by two sections butt joints; All there is steel plate at the pile cutoff two ends when manufacturing; General 18 ~ 22mm is thick, and the effect of steel plate has four: 1, the anchoring presstressed reinforcing steel, and main muscle passes through passage in the stretch-draw hole; Insert in another aperture, the anchor head that utilizes main muscle end to enlarge is stuck in the aperture.2, steel plate links together two pile sections through welding.3, the end plate back side is connected with the pile crown reinforcing rib through welding.4, coxopodite stake bottom plate and the welding of piling bar point (concrete stake point directly inserts no rigid connection the in the stake hole).
Pile tube uses the steel end plate to have following drawback:
1, consume great deal of steel, φ 500 is an example with the stake footpath, and every site operation adds up to 171 kg with welding rod 6.73 kg with steel plate 164 kg, and the civilian construction that one five unit is six layers are measured about 260 with stake, then consume 30.42 tons of steel.
2, weldquality has hidden danger; Weld interval is long, and field Welding can't be supervised, and the slag inclusion space is uncontrollable; Detecting the stake that goes wrong when checking and accepting all is in welded joints; It was injection in 8 minutes that weld seam is accomplished the anticorrosion cooling of mopping, anticorrosion cutting little ice, and can weld seam reach 50 years quality guarantee period, and who can hardly be explained.It is efficient at last to accomplish 14 piles in 11 hours, calculates in view of the above, and 50 minutes every pile times spent, welding, cooling just accounted for 30-40 minute, were restricting piling efficient.
3, the end plate processing cost is high, car, bore, mill, tapping all needs specialized operation, general pile tube factory impotentia is processed, the manufacturer that has practises fraud, and cylinder iron replaces the Q235 steel, has had a strong impact on welding quality.
When 4, small strain detects the integrality of stake, because steel plate material is compared Material Strength with intensity with concrete and differed greatly, according to regulation, be not suitable for doing the condition of small strain, small strain detects and has cloudy ideas.
5, stretch-draw hole and main muscle anchor hole all have the passage of a width greater than main muscle diameter, and this can cut down main sinew anchor head is stressed, and two Kong Jiayi grooves cause steel plate that weak link is arranged simultaneously, when welding, are easy to generate distortion.
Summary of the invention
The technical problem that the utility model will solve is the deficiency to prior art, the no steel end plate pile tube that proposed a kind ofly to realize rapid abutting joint, practice thrift steel, quality is high, efficient is high.
The technical problem that the utility model will solve realizes through following technical scheme; A kind of no steel end plate pile tube comprises coxopodite stake and last joint stake at least, is characterized in: the coxopodite stake with on the two ends of joint stake be equipped with concrete pile crown plate; Concrete pile crown plate comprises peripheral board; In peripheral board, be provided with the pile crown entity of steel concrete cast, in the pile crown entity, be embedded with and the main one to one muscle anchor tube of main muscle, between every two adjacent main muscle anchor tubes, be equipped with the stretch-draw butt tube; The inner of stretch-draw butt tube is provided with plug, and the outer end of stretch-draw butt tube is provided with stretch-draw butt joint silk hole.
The concrete pile crown plate of last joint stake lower end is the butt joint upper plate; The concrete pile crown plate of coxopodite stake upper end is the butt joint lower plate; In the stretch-draw butt joint silk hole of the stretch-draw butt tube in the butt joint upper plate anchor post is housed; The hypomere of anchor post is an anchoring section, and anchoring section has dilatation joint, is provided with the taper anchoring bracer that cooperates with the anchoring section dilatation joint in the butt tube in the butt joint lower plate.
The technical problem that the utility model will solve can also realize that further the outer end of main muscle anchor tube is provided with the stretch-draw holder of main muscle end cap through following technical scheme, stretch-draw holder symmetry be provided with left and right sides two halves.
The technical problem that the utility model will solve can also further realized, is fixedly connected with reinforcing rib on the plug of the inner of stretch-draw butt tube through following technical scheme.
The technical problem that the utility model will solve can also realize that further the upper end of taper anchoring bracer is set to coniform that the lower end of the anchoring section dilatation joint of anchor post is provided with the lead-in groove that cooperates with the awl point of anchoring bracer through following technical scheme.
The utility model compared with prior art; Be a kind of novel pile tube production, site operation joint mode; Cancel original pile cutoff steel end plate, replace with prefabricated concrete pile crown plate, the concrete pile crown plate of last joint stake lower end is the butt joint upper plate; The concrete pile crown plate of coxopodite stake upper end cooperates with the anchoring bracer through anchor post for the butt joint lower plate.During coxopodite stake and last joint stake butt joint, anchor post inserts in the butt tube of butt joint lower plate, and the weight pressure anchor of joint pile body, pile cover and hammer utilizations in, anchoring bracer are dovetail shaped along the dilatation joint of anchor post with anchoring section and strut the anchor connection between the realization double sectioned column.Reach rapid abutting joint, high saving, high environmental protection, high efficiency, high-quality purpose.
Every butt joint one pile is saved 0.116 ton of steel, and the construction unit of six layers of Unit five is about 260 with the stake amount, just can save 30.42 tons of steel.Aspect construction, two joint stake docking times are zero basically in addition, and the duration then can shift to an earlier date about 4/5; The every pile of operating expenses can be saved more than 126 yuan, brings very big advantage to market competition, is a desirable construction means; Be superior to adopting steel end plate welding procedure qualitatively in butt joint, sunshine case work is calculated simple and clear; It is ineffective thoroughly to have broken away from supervision, the problem that weldquality can't guarantee.The utility model manufacturing procedure is simple, and cost of manufacture is low, equipment investment is few, can concentrate, and also can disperse to produce, and is convenient to promote the use of.
