Abstract
The utility model discloses a stress application self-drilling pile, in particular to the building stress application self-drilling pile used in project engineering such as constructional engineering and expressway subgrade engineering, and aims to provide the stress application self-drilling pile which has high carrying capacity, is not required to be driven during the mounting process, and causes no noise or vibration. The stress application self-drilling pile comprises a pile body, wherein the pile body comprises two parts namely a cone and a cylinder, wherein the connecting part of the cone and the cylinder is the maximum diameter part of the cone; spiral strips are extended from the head part of the cone to the end part of the cylinder, and the distances from the tail ends of the spiral strips to the end part of the cylinder are no less than 50 cm. The stress application self-drilling pile has the characteristics of simple structure, convenience for use, reasonable design and the like.
Description
Technical field
The utility model relates to a kind of afterburning self tapping stake, is especially a kind ofly applied to the afterburning self tapping stake of building used in construction work, the projects such as express highway roadbed.
Background technology
At present in construction work, the projects such as express highway roadbed, generally be flat stake, need to afterburning self tapping stake be driven into underground reinforcing by pile driver, but use flat stake, in the process of piling, can produce larger sound and vibrations, make to have influence on the daily life of periphery resident family.
Also having now a kind of stake is to fill with stake, but this mode cost is high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of supporting capacity is strong, in installation process without piling and noiseless and shockproof afterburning self tapping stake.
In order to achieve the above object, the afterburning self tapping stake that the utility model is designed, it comprises pile body body, pile body body consists of centrum and cylinder two parts; The maximum gauge place that centrum and cylinder connection place are centrum, the head of centrum is extended with spiral bar to cylindrical end, and the end of spiral bar to cylindrical end distance is no less than 50cm place.
On described cylindrical head and perpendicular to the length direction of pile body body, be provided with groove, groove is preferably positioned at the center of cylinder head.
On the head of described centrum and perpendicular to the length direction of pile body body, be provided with groove, groove is preferably positioned at the center of centrum head.
According to the end of above-described spiral bar to cylindrical end, apart from the best, be 80cm.
Due to the centrum head of the pile body body having in depth under, so have water constantly to overflow, self tapping stake as afterburning in river course, the length direction of shaft body is provided with through hole, is convenient to water flowing and ventilation.
According to the above, the afterburning self tapping stake of the utility model gained, by increase spiral bar on pile body body, during use, afterburning self tapping stake is spun on underground by stake machine in the mode screwing, thereby can not produce piling sound and vibrations, the concrete strength of pile body body is C45, and supporting capacity improves 30% than other preformed piles.Therefore, it has the features such as simple in structure, easy to use and reasonable in design.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representations.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Embodiment 1:
As shown in Figure 1, the afterburning self tapping stake that the present embodiment is described, it comprises pile body body, pile body body consists of centrum 2 and cylinder 1 two parts; The maximum gauge place that centrum 2 and cylinder 1 junction are centrum, the external surface that the head of centrum 2 extends to the end of cylinder 1 is provided with spiral bar 3, and the end of spiral bar 3 to cylindrical end distance is 50cm place; The concrete strength of this pile body body is C45, and supporting capacity improves 30% than other preformed piles.
Embodiment 2:
As shown in Figure 2, the afterburning self tapping stake that the present embodiment is described, it comprises pile body body, pile body body consists of centrum 2 and cylinder 1 two parts; Centrum 2 is the maximum gauge place of centrum 2 with cylinder 1 junction, the head of centrum 2 is extended with spiral bar 3 to the end of cylinder 1, and the end of spiral bar 3 to the end distance of cylinder 1 is 50cm place, on the head of described cylinder 1 and perpendicular to the length direction of pile body body, be provided with groove 4, groove 4 is positioned at the center of cylinder 1 head; Due to centrum 2 heads of the pile body body having in depth under, so there is water constantly to overflow, the length direction of shaft body is provided with through hole 5, is convenient to water flowing and ventilation.
