Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Fig. 1 and Figure 11, a kind of preformed pile with concavo-convex chuck, comprise pile body 10, reinforcing cage 20 is provided with in pile body 10, the helical spiral reinforcement 22 that described reinforcing cage 20 comprises some longitudinal reinforcements 21 and is fixedly connected with longitudinal reinforcement 21, described pile body 10 comprises some interconnective heavy in section stakes 11 and small bore stake 12, described pile body 10 two ends are fixed with some tension nuts 30, the bottom of tension nut 30 reduces the chuck 31 being formed and can block pier nose 23, the two ends of longitudinal reinforcement 21 are provided with the pier nose 23 that external diameter is greater than longitudinal reinforcement 21, pier nose 23 is positioned at tension nut 30 and the chuck 31 of tension nut 30 can block pier nose 23, trumpet-shaped connector 32 is formed between the oral area of tension nut 30 and the end of pile body 10, connector can be inserted in connector 32, thus two pile bodies 10 are reinforced the connection.
In above-mentioned non-uniform pile, the tension of stake and flexural strength are completely by longitudinal reinforcement 21, and shearing resistance and skeleton forming are completely by spiral reinforcement 22, and the stretch-draw in manufacturing process realizes by the stretch-draw of tension nut 30 pairs of pier noses 23.
Above-mentioned heavy in section stake 11 or small bore stake 12 can be independently the stake of circular stake, oval stake, rectangular pile, triangular pile, polygonal pile, quincunx stake or other shapes simultaneously or separately.When the surface of heavy in section stake 11 or small bore stake 12 preferably can also adopt chamfered transition, thus make surface more smooth, not easily broken.As Figure 4-8, the cross sectional shape of pile body 10 is respectively hexagon, circle, square, rectangle and triangle.
At present, the production technology of the stake of using in building trade especially preformed pile is divided into centrifugal forming and vibration moulding two kinds.Circular stake and rectangular pile can adopt centrifugal forming, and the stake of other shapes can adopt vibration moulding.
Pile body 10 two ends are also provided with concavo-convex chuck mechanism 40, and when two adjacent pile bodies 10 are close to each other, described concavo-convex chuck mechanism 40 can allow two pile body 10 snap-fit engagement thus two pile bodies 10 are interconnected.
Specifically, concavo-convex chuck mechanism 40 comprises and is arranged on pile body 10 one end and to the concave station 41 of pile body 10 inner recess, also comprise and be arranged on pile body 10 other end and the boss 42 protruded to pile body 10 outside, described concave station 41 and the shape of boss 42, size matches, as Figure 4-Figure 6, boss 42 and concavo-convex 41 is preferably truncated cone, also can be triangle table as shown in Figure 8, rectangle platform as shown in Figure 7 or other shapes, when two pile bodies 10 are close to each other, boss 42 on one pile body 10 to be inserted in the concave station 41 on another pile body 10 thus to form snap-fit engagement.
Pile body 10 two ends are enclosed with angle protection cover 13; the setting of angle protection cover 13 is to prevent the end of pile body 10 broken; this angle protection cover 13 can adopt metal material to make; usually closed circular structure should be formed around the end of pile body 10; and pile body 10 angle protection cover 13 width had on concave station 41 one end is greater than the degree of depth of concave station 41, thus protect the bonding strength of concavo-convex chuck mechanism 40.
Tension nut 30 distributes uniformly around concave station 41 or boss 42 interval, that is tension nut 30 is located at the outside of concave station 41 or boss 42, do not affect the connection to concave station 41 and boss 42, and the shape that tension nut 30 distributes end shape that is usual and pile body 10 adapts, also namely when the end of pile body 10 is rounded, then tension nut 30 distributes ringwise, when the end of pile body 10 is rectangular, the then rectangular distribution of tension nut 30, when end as pile body 10 is hexagon, then tension nut 30 distribution in hexagon, by that analogy.Pull nut 30 when connecting to make two pile bodies 10 not collide, it is inner that tension nut 30 entirety is positioned at pile body 10.
Heavy in section stake 11 is connected by non-uniform pile 14 transition with the junction of small bore stake 12, and the two ends of non-uniform pile 14 are respectively heavy in section and small bore, and heavy in section end connects heavy in section stake 11, and small bore end connects small bore stake.
Preferred version, heavy in section stake 11 is connected by non-uniform pile 14 transition with slope 15 with the junction of small bore stake 12, the gradient on slope 15 can do corresponding adjustment according to during not the coexisting and make of soil property, slope 15 is linearly, be convenient to make and lower stake, certain slope 15 also can make negative camber or positive camber or spirality etc. into.
As shown in Figures 2 and 3, in order to reduce the cost of manufacture of pile body 10, hollow structure 50 is also provided with in pile body 10, this hollow structure 50 is by the closed at both ends of pile body 10 or the two ends being communicated with pile body 10, cross sectional shape can be circle as shown in Figure 9, hexagon as shown in Figure 10, alternatively rectangle, triangle, polygon etc., hollow structure 50 comprises the gas tank or hollow section filling out and be located at pile body 10 inside, gas tank also can adopt the elastomeric material of sealing to substitute, and the gas tank of tubulose is formed at the inner injecting compressed air of elastomeric material, hollow tube can adopt pvc pipe or PP pipe or steel pipe etc., no matter be gas tank or hollow tube, all can form fixing shape, thus make pile body 10 inside form hollow structure 50.
Certainly, hollow structure 50 can be arranged in heavy in section stake 11, also can be arranged in small bore stake 12, or is arranged in heavy in section stake 11 and small bore stake 12 simultaneously.Also can arrange multiple hollow structure 50 in pile body 10, multiple hollow structure 50 can be interconnected or independent separately.
Advantage of the present invention is, 1, concavo-convex chuck mechanism 40 is convenient to make two pile bodies 10 firmly connect fast when lower stake, and angle protection cover 13 strengthens the intensity of junction, further increases the application life of bonding strength and pile body 10; 2, heavy in section stake 11 and small bore stake 12 make pile body 10 surface presentation concaveconvex structure, thus improve anti-pulling capacity and the Compressive Bearing Capacity of pile body 10, prove through test, the anti-pulling capacity of the pile body 10 that pile body 10 specific surface of concaveconvex structure is smooth improves more than 70%, and Compressive Bearing Capacity improves more than 20% than smooth pile body 10; 3, the setting of hollow structure 50, reduces the cost of manufacture of pile body 10, is applicable to the field not high to resistance to compression requirement for bearing capacity.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
