Abstract
The invention belongs to the technical field of buildings and relates to an uplift pile. The uplift pile comprises a pile body which is formed by connecting a plurality of pile main bodies with the sectional areas gradually increased from top to bottom, and a step part is formed on the joint of every two adjacent pile main bodies. According to the uplift pile, on the basis of the principle that the pulling property of the pile bodies is sequentially enhanced from the soil layer superficial position to the deep position, the pile bodies which are gradually increased are arranged to form the step parts, the pulling resistance can be good in each soil layer, and the pulling property is substantially improved.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Embodiment 1
As shown in Figure 1, a kind of uplift pile, comprises pile body 1, described pile body 1 by some sections from top to bottom sectional area become large pile body 2 successively and be formed by connecting, the junction of every two adjacent pile bodies 2 forms stage portion 3.
Preferably, the cross section of pile body 2 is square, H-shaped, triangle, circle, hexagon or octagon.The sectional area being positioned at the pile body 2 at pile body 1 top is 1:4-10 with the ratio of the sectional area of the pile body 2 be positioned at bottom pile body 1.Plane residing for the surface of stage portion 3 is vertical with the axial line of pile body 1.The height of each pile body 2 is identical.
Preferably, the two ends of pile body 1 are fixed with some attaching nuts 4, be provided with some dowels 5 in described pile body 1, the two ends of dowel 5 are fixedly connected with the attaching nut 4 at pile body 1 two ends respectively, and dowel 5 can be rod iron, steel strand, reinforcing bar, carbon fiber rod etc.As shown in Figure 3, form chuck 6 bottom attaching nut 4 after reducing, rear formation boss 7 is expanded at the two ends of described dowel 5, and described boss 7 is with chuck 6 snap-fit engagement thus dowel 5 is fixedly connected with attaching nut 4.
Those skilled in the art are to be understood that, pile body 1 represents a complete stake, he can be an independent pile, also can be that many piles are axially connected to form the pile body 1 with certain length, as for the method for attachment of pile body, be then the common practise of those skilled in the art, have the stake of end plate end plate can be adopted to weld thus axially connect, the stake of end-plate-free can adopt connector shaft to connection.
As shown in Figure 2, pile body 1 can many be formed by connecting, thus reach the length of needs, the material connecting pile body 1 can be connector, the patent that the concrete structure of connector and operating principle are applied for before seeing the applicant.If application number is 201510314380.0; 200810060180.7; 200810060181.1 patent.Because connector is prior art, therefore repeat no more herein.
The from top to bottom that is all load of all loads on stake top all to be born responsibility load by stake, the power of resistance to plucking bearing peg is from stake periphery frictional force, so the bearing capacity size of stake is again the frictional force quality coming from a periphery soil, the better bearing capacity of frictional force of stake periphery is larger, stage portion 3 between the pile body 2 of the application forms bearing support power, can obtain carrying frictional force between different soil layers, thus avoid the defect that causes frictional force to reduce because soil layer is bad, improve the load-carrying properties of pile body 1.The stage portion 3 of this uplift pile is formed vertically successively, thus makes stage portion 3 be arranged in different soil depths and soil property, and soil property at different levels can play resistance to compression support effect to pile body 1, substantially increases extraction-resistant behavior.
