Description
Technical field
The present invention relates to a kind of foundation pile docking structure, especially can the automatic rapid spiral thread form docking structure of foundation pile of rapid abutting joint automatically。
Background technology
Pile foundation is by the power transmission rod member with certain rigidity and bending resistance of incoming for superstructure load ground, is a kind of ancient and common deep foundation form.Pile foundation is compared with other base forms, there is bearing capacity height, deform little and uniform, materials and economize, mechanization of building operation degree high, almost going for all kinds of geological conditions and various types of engineering construction, therefore its application in all types of industries with civil building engineering is widely.At present, difference due to the reason of some geology and bearing capacity size, generally require several foundation stake docking and form pile foundation, and foundation pile docking method mostly at the two ends of foundation pile respectively equipped with steel plate, again two block plates are welded when two foundation stakes to be docked, thus complete docking, but this foundation pile docking calculation complex operation, time-consuming bothersome and cost is high。
Summary of the invention
For the problem overcoming existing foundation pile docking calculation complex operation, time-consuming bothersome and cost is high, the invention provides a kind of automatic rapid spiral thread form docking structure of foundation pile, this foundation pile automatic rapid spiral thread form docking structure simple in construction, cost is low, save time and save trouble and solid and reliable, it may be achieved the automatic rapid spiral thread form docking of foundation pile.
The technical solution adopted for the present invention to solve the technical problems is: this foundation pile automatic rapid spiral thread form docking structure includes top foundation pile waiting, frustum tooth, the external screw thread frustum of a cone, female thread frustum of a cone groove, cone wall tooth and bottom foundation pile waiting；The end of foundation pile lower end waiting on top, axially it is provided with the external screw thread frustum of a cone with raised thread stretching out prolongation, the frustum tooth at the interval that distribution has and thread rotary orientation on the external screw thread frustum of a cone is consistent evenly around of external screw thread frustum of a cone upper end and frustum alveolus, the end of foundation pile upper end waiting in bottom, axially it is provided with and mates the female thread frustum of a cone groove coincideing with the external screw thread frustum of a cone, the distribution evenly around of female thread frustum of a cone groove upper end has the cone wall alveolus docked with frustum tooth thread form, and cone wall alveolus staggers with cone wall tooth spacer；After bottom foundation pile waiting squeezes into ground, when leaving the female thread frustum of a cone groove of exposed end on the ground, namely can carry out screw thread with top foundation pile waiting and spiral thread form is mutually butted, when docking, the outside of threaded circular frustum and frustum tooth and the inside of female thread frustum of a cone groove and cone wall alveolus are coated with quick-drying high-strength cement slurry outside, are so namely capable of the quickly firm docking between foundation pile.
The described external screw thread frustum of a cone is selected 2～30 protruding trapezoidal threads, in female thread frustum of a cone groove, has the thread groove of corresponding bar number；When beyond the selection of this thread pitch, threaded circular frustum inserts in female thread frustum of a cone groove, it is possible to the gravity automatic rotary against pile body self drops down onto female thread frustum of a cone bottom portion of groove and is as the criterion.
Concrete on the inside of the described external screw thread frustum of a cone and the wall of female thread frustum of a cone groove presets straight-through steel bar piece and peripheral members, to increase the external screw thread frustum of a cone and the intensity of female thread frustum of a cone groove, after making docking mutually, foundation pile ensures to become a bulk strength.
During the docking of described upper and lower foundation pile waiting, frustum tooth and cone wall alveolus rotate the docking that coincide, frustum alveolus and cone wall tooth and rotate the docking that coincide, thus the thread form docking formed between foundation pile, it is possible to very firmly upper and lower foundation pile waiting is butted into for an entirety.
The invention has the beneficial effects as follows: this foundation pile automatic rapid spiral thread form docking structure simple in construction, cost is low, save time and save trouble and solid and reliable, it may be achieved the automatic rapid spiral thread form docking of foundation pile.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is that grafting principle circular arc of the present invention cuts open structural representation.
1. top foundation pile waiting in figure, 2. frustum tooth, 3. the external screw thread frustum of a cone, 4. female thread frustum of a cone groove, 5. cone wall tooth, 6. bottom foundation pile waiting.
Detailed description of the invention
In the drawings, this foundation pile automatic rapid spiral thread form docking structure includes top foundation pile waiting 1, frustum tooth 2, the external screw thread frustum of a cone 3, female thread frustum of a cone groove 4, cone wall tooth 5 and bottom foundation pile 6 waiting；The end of foundation pile 1 lower end waiting on top, axially it is provided with the external screw thread frustum of a cone 3 with raised thread stretching out prolongation, the frustum tooth 2 at the interval that distribution has and thread rotary orientation on the external screw thread frustum of a cone 3 is consistent evenly around of the external screw thread frustum of a cone 3 upper end and frustum alveolus, the end of foundation pile 6 upper end waiting in bottom, axially it is provided with and mates the female thread frustum of a cone groove 4 coincideing with the external screw thread frustum of a cone 3, the distribution evenly around of female thread frustum of a cone groove 4 upper end has the cone wall alveolus docked with frustum tooth 2 thread form, cone wall alveolus and cone wall tooth 5 interval to stagger；After bottom foundation pile 6 waiting squeezes into ground, when leaving the female thread frustum of a cone groove 4 of exposed end on the ground, namely can carry out screw thread with top foundation pile 1 waiting and spiral thread form is mutually butted, when docking, the outside of threaded circular frustum 3 and frustum tooth 2 and the inside of female thread frustum of a cone groove 4 and cone wall alveolus are coated with quick-drying high-strength cement slurry outside, are so namely capable of the quickly firm docking between foundation pile.
The described external screw thread frustum of a cone 3 is selected 2～30 protruding trapezoidal threads, in female thread frustum of a cone groove 4, has the thread groove of corresponding bar number；When beyond the selection of this thread pitch, threaded circular frustum 3 inserts in female thread frustum of a cone groove 4, it is possible to the gravity automatic rotary against pile body self drops down onto and is as the criterion bottom female thread frustum of a cone groove 4.
Concrete on the inside of the described external screw thread frustum of a cone 3 and the wall of female thread frustum of a cone groove 4 presets straight-through steel bar piece and peripheral members, to increase the external screw thread frustum of a cone 3 and the intensity of female thread frustum of a cone groove 4, after making docking mutually, foundation pile ensures to become a bulk strength.
During the docking of described upper and lower foundation pile waiting, frustum tooth 2 and cone wall alveolus rotate the docking that coincide, frustum alveolus and cone wall tooth 5 and rotate the docking that coincide, thus the thread form docking formed between foundation pile, it is possible to very firmly upper and lower foundation pile waiting is butted into for an entirety。
