Abstract
This utility model provides a kind of fin opening concrete hollow pile tube, including mold and lower mold, described mold and described lower mold outer wall are provided with pile tube outer wall fin, described mold and described lower mold inwall are provided with pile tube inwall fin, and described pile tube outer wall fin and pile tube inwall fin include in the middle part of annular protruding rib bottom, annular protruding rib and annular protruding rib top.This utility model fin open hollow pile tube is every a segment distance ring-like ribs the most arranged in a crossed manner at the outer wall of traditional circular cross-section hollow pile tube and inwall.Owing to being additionally arranged ring-like ribs, add the surface area that stake contacts with the soil body, be effectively increased pile body frictional force and the bearing capacity of whole stake.Pile tube inwall fin and outer wall fin uniform crossover are arranged.Novel fin open hollow pile tube continues to use traditional construction technique, uses pretensioned prestressing technique and centrifugal casting to be made in precast plant.
Description
Technical field
This utility model belongs to construction engineering technical field, relates to a kind of fin opening concrete hollow pile tube.
Background technology
Along with the development of building technology, pile foundation construction field makes rapid progress especially.Prestressed high-strength concrete pile because of
It is many excellent that it has that speed of application is fast, price is low, bearing capacity is high, steady quality, curing time are short, easy construction is nuisanceless etc.
Point so that it is be widely used in basement process, but for a lot of soft soil foundations, muck foundation.To with frictional force
Being designed as main traditional pile for prestressed pipe, its frictional force improves little.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of fin opening concrete hollow
Pile tube, is additionally arranged ring-like ribs, adds the surface area that stake contacts with the soil body, is effectively increased holding of pile body frictional force and whole stake
Load power, can effectively solve the problem in background technology.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model provides a kind of fin opening concrete hollow pile tube, including mold and lower mold, described upper mold
Tool and described lower mold outer wall are provided with pile tube outer wall fin, described mold and described lower mold inwall, and to be provided with pile tube inwall convex
Rib, described pile tube outer wall fin and pile tube inwall fin include in the middle part of annular protruding rib bottom, annular protruding rib and on annular protruding rib
Portion.
As a kind of optimal technical scheme of the present utility model, in described lower mold, it is placed with framework of steel reinforcement, described lower mold
Pour concrete, described mold and described lower mold in tool to be bolted.
Compared with prior art this utility model is reached to provide the benefit that: this utility model fin open hollow pile tube
It is every a segment distance ring-like ribs the most arranged in a crossed manner at the outer wall of traditional circular cross-section hollow pile tube and inwall.Due to
It is additionally arranged ring-like ribs, adds the surface area that stake contacts with the soil body, be effectively increased pile body frictional force and the bearing capacity of whole stake.
Pile tube inwall fin and outer wall fin uniform crossover are arranged.Novel fin open hollow pile tube continues to use traditional construction technique, in advance
Factory processed uses pretensioned prestressing technique and centrifugal casting to be made.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment: as Figure 1-3, this utility model provides a kind of fin opening concrete hollow pile tube, including upper mold
Tool 5 and lower mold 6, described mold 5 and described lower mold 6 outer wall are provided with pile tube outer wall fin 1, described mold 5 and described
Lower mold 6 inwall is provided with pile tube inwall fin 2, and described pile tube outer wall fin 1 and pile tube inwall fin 2 include under annular protruding rib
In the middle part of portion 7, annular protruding rib 8 and annular protruding rib top 9.
It is placed with framework of steel reinforcement 3 in described lower mold 6, in described lower mold 6, pours concrete 4, described mold 5 He
Described lower mold 6 is bolted.
Quality steel plate is selected to make mold 5 and lower mold 6.The subsidiary ring-like ribs of outer mold wall, the subsidiary ring of mould inner wall
Shape fin, wherein pile tube outer wall fin 1 and pile tube inwall fin 2 contain in the middle part of annular protruding rib bottom 7 and fin 8 and fin
Top 9, sprays releasing agent after dimension control is qualified.The framework of steel reinforcement made is positioned in lower mold 6, casting concrete 4,
At many casting concretes of trying one's best at stretch-draw end and ring-like ribs, mold 5 and lower mold 6 are carried out matched moulds, use spiral shell
Bolt fixing compact；Next stretch-draw, centrifugal forming；Form removal after steam press maintenance, novel fin opening concrete hollow pile tube is just made
Complete.
This utility model fin open hollow pile tube be the outer wall of traditional circular cross-section hollow pile tube and inwall every
One segment distance ring-like ribs the most arranged in a crossed manner.Owing to being additionally arranged ring-like ribs, add the surface area that stake contacts with the soil body,
It is effectively increased pile body frictional force and the bearing capacity of whole stake.Pile tube inwall fin 1 and outer wall fin 2 uniform crossover are arranged.Novel
Fin open hollow pile tube continues to use traditional construction technique, uses pretensioned prestressing technique and centrifugal casting to make in precast plant
Form.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature
Carry out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
