Description
Technical field
This utility model relates to the pile foundation of building, specifically a kind of easy construction, simple to operate, can be the most pre-
Stake connector processed.
Background technology
It is known that the basis of building typically all uses concrete-pile, to this end, JGJ94-2008 " building pile foundation technology
Specification " in, specially technology requirement being proposed concrete-pile, the square pile currently used is usually prestressed-concrete pile, such as patent
Number being 2012100044922, patent name is " prestressed concrete solid pile and manufacture method ", and it contains steel reinforcement cage, mixed
Solidifying soil and steel reinforcement cage, steel reinforcement cage is combination type overall structure, uses slip welding method to be welded by precast square pile steel reinforcement cage during use
Connecing and form, pile body two ends are provided with the metal end plate being connected with steel reinforcement cage, and the stirrup of steel reinforcement cage is welded on main muscle in the shape of a spiral, steel
The main muscle of muscle cage uses high pre-stress rod iron, is first located at diameter on the metal foil that rod iron two ends are corresponding little during the stretch-draw of rod iron
In the hole, location of rod iron, it is provided with diameter in the side in hole, location more than location bore dia and passing that location pore radius coincides
Hole, when assembling steel reinforcement cage, first by rod iron two ends jumping-up (diameter is more than location bore dia), then by rod iron from through hole through metal
Steel plate moves to position in hole, to realize the connection of rod iron and metal foil, then selects diameter to be not more than 6mm reinforcing bar and uses slip
Welding method welding tie hoop, to form cage and to reserve stretch-draw silk eye at cage two ends metal end plate, by the two of puller system
Pull end is connected with the tensioning equipment on the metal foil of cage two ends respectively, uses puller system that the prestressing force of rod iron is pulled to 0.7 σ-0.9
σ, the intensity of this steel must is fulfilled for every square millimeter and also pours into a mould concrete more than 1420 newton, making antirust treatment, when mixed
When solidifying soil intensity reaches 60-70%, unclamping tensioning equipment mould unloading, the degree of depth according to stake during use, through the metal end of stake end
Plate is welded to form pile body, the deficiency of this high pre-stress square pile: one is that design is unreasonable, owing to the pre-add of high pre-stress reinforcing bar should
Power the biggest and invisible increase pile body additional stress, thus cause bearing capacity of pile to reduce；Two is that domestic prestressed steel bar is maximum straight
Footpath is 12.5mm, although intensity is high, but little with regular screw threads steel phase diameter group, big by corrosion loss rate under equal conditions；Three are
The performance of prestressed steel bar is high intensity, underrelaxation, and elongation is little, the foundation pile poor seismic behavior made of it；Four be pile body by
The prefabricated pile metal foil through end is weldingly connected, and Joining Technology must be Site Welding, then carries out anti-corrosion treatment, has and executes
The deficiencies such as work environment is poor, inefficiency, connection weak effect.If it addition, above-mentioned technique uses regular screw threads steel to make square pile,
Then there is regular screw threads steel to there are differences at diameter and profile with prestressed steel bar, because selecting HRB400 screw-thread steel diameter thick, choosing
By traditional heading, end plate tensioning process difficulty.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, it is provided that a kind of raw easy construction, simple to operate,
Work efficiency is high, the prefabricated pile connector of good connecting effect.
This utility model solves its technical problem and be the technical scheme is that
A kind of prefabricated pile connector, it is characterised in that be provided with the stepped cylinder that upper end diameter is big, bottom diameter is little
Body, inner nut, snap ring, back-up ring and spring, stepped cylinder upper end is provided with outside matching with prefabricated pile internal thread of sleeve
Screw thread, stepped cylinder lower end is provided with the draw-in groove matched with snap ring inwall, and inner nut is the union body of a band convex edge, upper end,
Its outer wall is provided with the external screw thread matched with prefabricated pile internal thread of sleeve, inwall and stepped cylinder bottom matched in clearance,
The draw-in groove of the corresponding stepped cylinder lower end of inner nut lower end inner wall is provided with the interior chamfering matched with snap ring outer wall, stepped circle
Cylinder is connected with inner nut with interior chamfering through draw-in groove, snap ring,
Snap ring described in the utility model is made up of 4-6 sheet arc frustum fixture block, the inner face of arc fixture block and outer face
In part-conical face,
The convex edge, upper end of inner nut described in the utility model is diametrically identical with sleeve diameter cylindric, on inner nut
End face is plane, and upper surface is provided with in-line open slot, to facilitate the connection of inner nut and sleeve.
Spring described in the utility model is spiral spring, and its elastic force primarily serves spiral shell in stepped cylinder inserts
Time female, make card block reset, lock cylinder, to realize connecting locking.
This utility model improves the stability of prefabricated pile, corrosion resistance and anti-seismic performance, it is to avoid prefabricated pile is combined into
Pile body must the deficiency of site operation, have simple to operate, work efficiency is high, improve the overall stability of pile body, antidetonation
Performance, decay resistance and service life, there is good economic benefit and social benefit.
