Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1 and Figure 11, a kind of prefabricated pile of band bumps chuck, including pile body 10, pile body 10 is interior to be equipped with steel reinforcement cage
20, the steel reinforcement cage 20 includes several longitudinal reinforcements 21 and the helical spiral reinforcement being fixedly connected with longitudinal reinforcement 21
22, the pile body 10 includes that several big section stakes 11 interconnected and small bore stake 12,10 both ends of pile body are fixed
There are several tension nuts 30, the bottom of tension nut 30 reduces to form the chuck 31 that can block pier nose 23, and the two of longitudinal reinforcement 21
End is equipped with the pier nose 23 that outer diameter is greater than longitudinal reinforcement 21, and pier nose 23 is located in tension nut 30 and 31 energy of chuck of tension nut 30
Pier nose 23 is blocked, horn-like connector 32 is formed between the oral area of tension nut 30 and the end of pile body 10, in connector 32
In connector can be inserted, thus make two pile bodies 10 reinforce connection.
In above-mentioned non-uniform pile, the tension and bending strength of stake lean on longitudinal reinforcement 21 completely, and shearing resistance and skeleton forming are complete
Spiral reinforcement 22 is leaned on entirely, and the tensioning in production process realizes the tensioning of pier nose 23 by tension nut 30.
Above-mentioned big section stake 11 or small bore stake 12 can be simultaneously or independent for round stake, oval stake, square
Shape stake, triangular pile, polygonal pile, quincunx stake or the stake of other shapes.When the surface of big section stake 11 or small bore stake 12
Chamfered transition can also be preferably used, thus keep surface more smooth, it is non-breakable.As shown in Figure 4-8, the section shape of pile body 10
Shape is respectively hexagon, circle, square, rectangle and triangle.
Currently, the production technology of the stake used in building trade especially prefabricated pile is divided into centrifugal forming and vibration moulding two
Kind.Round stake and rectangular pile can use centrifugal forming, and the stake of other shapes can use vibration moulding.
10 both ends of pile body are additionally provided with concave-convex chuck mechanism 40, and when two adjacent pile bodies 10 are close to each other, described is recessed
Convex clip platform mechanism 40 can allow two pile bodies 10 to be engaged by clamping to be connected with each other two pile bodies 10.
Specifically, concave-convex chuck mechanism 40 includes 10 one end of pile body being arranged in and to the concave station of 10 inner recess of pile body
41, it further include that 10 other end of pile body is set and to the boss 42 protruded outside pile body 10, the concave station 41 and boss 42
Shape, size match, and as Figure 4-Figure 6, boss 42 and the preferably truncated cone of bumps 41 are also possible to as shown in Figure 8
Triangle table, rectangle platform as shown in Figure 7 or other shapes, the boss when two pile bodies 10 are close to each other, on a pile body 10
To form clamping engagement in 42 concave stations 41 that can be inserted on another pile body 10.
10 both ends of pile body are enclosed with angle protection cover 13, and the setting of angle protection cover 13 is that the end of pile body 10 in order to prevent is broken, should
Angle protection cover 13 can be made of metal material, and closed circular structure, and pile body 10 should be usually formed around the end of pile body 10
It is greater than the depth of concave station 41 with 13 width of angle protection cover on 41 one end of concave station, to protect the connection of concave-convex chuck mechanism 40 strong
Degree.
Tension nut 30 is around concave station 41 or the evenly spaced distribution of boss 42, that is to say, that tension nut 30 is located at concave station
41 or boss 42 outside, do not influence the connection to concave station 41 and boss 42, and the shape that tension nut 30 is distributed usually with stake
The end shape of body 10 is adapted, namely when the end of pile body 10 is rounded, then tension nut 30 is distributed in a ring, works as pile body
When 10 end is in rectangle, then tension nut 30 is in distributed rectangular, when as hexagonal such as the end of pile body 10, then tension nut 30
Hexagonal distribution, and so on.It does not collide to make two pile bodies 10 pull nut 30 when connecting, tension nut 30 is whole
Body is located inside pile body 10.
Big section stake 11 is connected with the junction of small bore stake 12 by 14 transition of non-uniform pile, the both ends of non-uniform pile 14
Respectively big section and small bore, big section end connect big section stake 11, and small bore end connects small bore stake.
The junction of preferred embodiment, big section stake 11 and small bore stake 12 passes through 14 transition of non-uniform pile with slope 15
The gradient of connection, slope 15 can do corresponding adjustment in production according to the different of soil property, and slope 15 is linearly, is convenient for
Production and lower stake, certain slope 15 can also be changed to negative camber or positive camber or spiral shape etc..
As shown in Figures 2 and 3, in order to reduce the cost of manufacture of pile body 10, it is additionally provided with hollow structure 50 in pile body 10, in this
Hollow structure 50 can be circle as shown in Figure 9 by the closed at both ends of pile body 10 or the both ends of connection pile body 10, cross sectional shape
Shape, hexagon as shown in Figure 10, it may also be said to which rectangle, triangle, polygon etc., hollow structure 50 include filling out to be located at pile body
Gas tank or hollow pipe inside 10, gas tank can also be using the elastic material substitution of sealing, and pressure is injected inside elastic material
Contracting air forms the gas tank of tubulose, and hollow tube can be using pvc pipe or PP pipe or steel pipe etc., either gas tank or hollow
Pipe, can form fixed shape, to make to form hollow structure 50 inside pile body 10.
Certainly, hollow structure 50 can be set in big section stake 11, also can be set in small bore stake 12, either
Setting simultaneously is in big section stake 11 and small bore stake 12.Multiple hollow structures 50, Duo Gezhong can also be set in pile body 10
Hollow structure 50 can be interconnected or respective independence.
It is an advantage of the invention that 1, concave-convex chuck mechanism 40 is convenient for connecting two pile bodies 10 quickly firmly
It connects, angle protection cover 13 strengthens the intensity of junction, further improves the service life of bonding strength and pile body 10；2, big section
Stake 11 and small bore stake 12 make 10 surface of pile body that concaveconvex structure be presented, to improve the anti-pulling capacity of pile body 10 and resistance to compression is held
Power is carried, tests prove that, 70% or more the anti-pulling capacity raising of the smooth pile body 10 of 10 specific surface of pile body of concaveconvex structure, and
Compressive Bearing Capacity improves 20% or more than smooth pile body 10；3, the setting of hollow structure 50 reduces being fabricated to for pile body 10
This, suitable for the field not high to resistance to compression requirement for bearing capacity.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
