Abstract
The invention discloses a prestressed pipe pile combined structure which comprises a pile body and a pile connector. The pile body is in a hollow cylinder shape. Internal threads are arranged on the inner side walls at the two ends of the pile body. The pile connector comprises a cylindrical part arranged in the middle portion and pointed cones arranged at the two ends, wherein external threads matched with the internal threads on the inner side wall of the pile body are arranged on the periphery of the cylindrical part, and the pile connector is screwed to one end of the pile body through the cylindrical part. In the use process, all pipe piles can be spliced through corresponding pile connectors conveniently, after the lower end of the pipe pile located at the lowest portion is connected with the corresponding pile connector, the pointed cone at one end of the pile connector will be exposed, and the pipe pile can more conveniently sink into the underground stratum through the corresponding pointed cone. Therefore, the prestressed pipe pile combined structure can be combined and spliced flexibly, construction is convenient, and complexity and cost of design and construction are effectively reduced.
Description
Technical field
The invention belongs to technical field of buildings, be specifically related to a kind of pile for prestressed pipe combining structure.
Background technology
Pile for prestressed pipe is widely used in the Foundation Design of modern architecture.Especially for the building built on unstable soil layer or Soft Soil Layer and infrastructure projects, pile for prestressed pipe is by being passed to the load of building on the stable rock stratum of underground, thus support of buildings, guarantee its safety.
The length of current pile tube, generally between 5m to 15m, generally needs many root canal piles to splice and uses during construction.Lowermost pile tube is in order to sink to underground better, and the lower end of this pile tube generally can be arranged to pointed cone structure thus more convenient pile tube press-in sub-surface, and its top is then connected with another pile tube by splicing device.The two ends of other pile tube are all then carry out compact siro spinning technology by splicing device and another pile tube.Lowermost tube pile structure can not be general for the tube pile structure spliced with other, and splicing device and the pointed cone structure for being pressed into sub-surface need to design respectively.Therefore, it is complicated to there is design in current pile tube, troublesome defect of constructing.
Summary of the invention
For above technical problem, the invention provides a kind of pile for prestressed pipe combining structure, its structure is simple, can splice and combine neatly, easy construction.
The technical scheme that the present invention adopts for its technical problem of solution is:
A kind of pile for prestressed pipe combining structure, comprise pile body and splicing device, described pile body is hollow cylindrical, the inside wall at described pile body two ends is provided with internal thread, described splicing device comprises the cylindrical portion being located at middle part and the taper being located at two ends, the periphery of cylindrical portion is provided with the external screw thread mated with internal thread on pile body inside wall, and splicing device is screwed by cylinder and is installed on pile body one end.
As preferred embodiment, the periphery of described taper is provided with guiding screw thread.
As preferred embodiment, the density of described guiding screw thread increases from the bottom of taper gradually to end.
As preferred embodiment, the medium position place of the cylindrical portion of described splicing device is provided with protruding parting bead.
The invention has the beneficial effects as follows: when the present invention uses, each pile tube can splice conveniently by splicing device, and after the pile tube lower end being positioned at bottom connects splicing device, the taper of splicing device one end can expose, and under the effect of taper, pile tube can sink to sub-surface more easily.Therefore, the present invention can carry out combined and spliced neatly, easy construction, effectively reduces design, the complexity of constructing and cost.

Fig. 2 is the structural representation of splicing device of the present invention;
Fig. 3 of the present inventionly combinationally uses schematic diagram.
Accompanying drawing illustrates: 1-pile body, 2-splicing device, 3-parting bead, 4-guides screw thread, 5-internal thread, 6-nut, 7-external screw thread.
Detailed description of the invention
See figures.1.and.2, a kind of pile for prestressed pipe combining structure of the present invention comprises pile body 1 and splicing device 2.Pile body 1 is hollow cylindrical, and the inside wall at pile body 1 two ends is provided with internal thread 5.Consider that pile body 1 is made for concrete material, therefore in order to arrange internal thread 5 more easily, the two ends of pile body 1 can be fixed with the nut 6 of form fit, and this nut 6 adopts cast iron materials to make, and internal thread 5 is located on nut 6.
The general cast iron materials that also adopts of splicing device 2 of the present invention is made.The middle part of splicing device 2 is cylindrical portion, and the periphery of cylindrical portion is provided with the external screw thread 7 mated with internal thread 5 on pile body 1 inside wall, and splicing device 2 can be screwed on the end of pile body 1 by the external screw thread 7 in cylindrical portion, thus is fixed.When splicing device 2 be applied to connect between two pile bodies 1 time, the two ends up and down of cylindrical portion screw on two pile body 1 ends respectively.For ease of controlling, the medium position of cylindrical portion is preferably provided with protruding parting bead 3, during assembling, splicing device 2 screws in can lock to the position touching parting bead 3.
The present invention is respectively equipped with taper at the two ends of the cylindrical portion of splicing device 2.After the pile tube lower end being positioned at bottom connects splicing device 2, the taper of splicing device 2 one end can expose, and under the effect of taper, pile tube can sink to sub-surface more easily.And under general service condition, taper can be inserted in the hollow cavity of pile body 1, can not have an impact to the screwing operations of pile body 1 and splicing device 2.
Better in order to make the soil layer of taper penetrate guide effect, the periphery of taper can be provided with further and guide screw thread 4, more preferably, guides the density of screw thread 4 to increase gradually from the bottom of taper to end.This guides screw thread 4 can order about taper and is inserted into better in soil layer, constructs convenient.
The structure that combinationally uses of the present invention is with reference to Fig. 3.Pile body 1 of the present invention and splicing device 2 can form whole piece pile tube neatly and use.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
