Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As Figure 1-3, a kind of prestressed concrete henry anisetree fruit square pile, comprise square pile body 10, described square pile body 10 comprises the heavy in section square pile 101 be arranged alternately and small bore square pile 102, the two ends of square pile body 10 can be heavy in section square pile 101 simultaneously or be small bore square pile 102 simultaneously, also can one end be small bore square pile 102, the other end be heavy in section square pile 101.
Square pile body 10 forms anistree square pile after excising 4 angles, and 4 angle sizes that square pile body 10 excises are identical and cross section is right-angled triangle.The two ends of square pile body 10 are provided with several can allow two interconnective connectors 11 of square pile body 10, connector 11 can be one or more, as connector 11 only has one, then be located on the center line of square pile body 10, if multiple, then can evenly be arranged on square pile body 10, described connector 11 comprises the protrusion plug-assembly 20 of square pile body 10 one end and the slot component 30 of recessed square pile body 10 one end, plug-assembly 20 and slot component 30 lay respectively at the two ends of square pile body 10, and when the plug-assembly 20 of a square pile body 10 is inserted in the slot component 30 of another square pile body 10, plug-assembly 20 and slot component 30 are tightly connected, obviously, plug-assembly 20 on same square pile body 10 and the position of slot component 30 are mutually one to one.Connected by draft angle 103 between heavy in section square pile 101 and small bore square pile 102.
The utility model relatively and the round stake of prior art and the junction plate of being located at round stake two ends have following advantages:
1, junction is not easily corroded, and can extend the connection lifetime between stake and stake thus the application life of prolongation stake.Existing stake is provided with the steel plate connected usually at two ends, two adjacent stakes connect stake by fixing formation of Plate Welding, after being pressed into underground when piling, due to the especially villaumite that contains salt in soil, corrosion can be formed to the steel plate be exposed in soil, cause the junction between stake and stake to be ruptured, thus connection stake is disconnected.
2, vertically pulling-resistant bearing capacity is strong.It is concavo-convex that heavy in section square pile 101 and small bore square pile 102 make square pile body 10 be formed, and improves the frictional force between square pile body 10 and soil, thus significantly improve the vertically pulling-resistant bearing capacity of square pile body 10.
3, stock utilization is high.Having of the square pile made with identical material has higher vertical bearing capacity than the stake of round stake or other shapes, and vertical bearing capacity is directly proportional to the area of stake, and the height that the area of stake equals stake takes advantage of the girth of stake.For example, for square pile and the circle stake of same height, suppose that the length of side of square pile is 4 meters, then girth is 16 meters, and circle stake will reach identical girth, then radius is necessary for 2.55 meters (pi gets 3.14), and at this moment the sectional area of square pile is 16 square metres, and the sectional area of circle stake is 20.4 square metres.Obviously, justify stake and just can reach the vertical bearing capacity identical with square pile than the more concrete material of square pile.
As shown in Figure 4, plug-assembly 20 comprises the plug base 21 be fixed in square pile body 10 and the plug 22 extending square pile body 10 outside, described slot component 30 comprises the slot 31 be fixed in square pile body 10 and the joint ring 32 be fixedly connected with the oral area of slot 31, joint ring 32 can adopt the materials such as rubber, polytetrafluoroethylene (PTFE), epoxy resin to make, when plug 22 is inserted in slot 31, plug 22 and joint ring 32 are tightly connected.The bottom of plug base 21 and slot 31 is connected with the pin 12 extending to square pile body 10 inside, and pin 12 is for improving the bonding strength of plug base 21 and slot 31 and square pile body 10.In addition, the sealing means between two square pile bodies 10 can adopt and arrange rubber pad or O type circle etc. at square pile body 10 two ends and realize sealing, but effect does not have the good of joint ring 32.
Preferred version, plug 22 and plug base 21 are demountable structure, one end that plug 22 is adjacent with plug base 21 is provided with the female screwed hole 23 of tool, plug base 21 is provided with has externally threaded stud 24, described stud 24 cooperatively interacts with screwed hole 23, when stud 24 is spirally connected with screwed hole 23, described plug 22 is spirally connected with plug base 21.This design is convenient to dismantle plug 22, prevents plug 22 from transportation, running into impact damage.
Plug 22 comprises connection-peg 221 and Plug Division 222, connection-peg 221 and screwed hole 23 are positioned at the two ends of Plug Division 222, described Plug Division 222 is in large lower young rounding taper type suitable for reading, the inner chamber of described joint ring 32 is the rounding taper type under large end opening suitable for reading, Plug Division 222 cooperatively interacts with the inner chamber of joint ring 32, formed and seal closely, described connection-peg 221 is in the little cydariform broad in the middle in two.
Be positioned at below joint ring 32 and be provided with a snap ring 40 in slot 31, when Plug Division 222 is inserted in slot 31, described snap ring 40 is fastened on Plug Division 222, improves the bonding strength between plug 22 and slot 31.
Also be provided with an elastic component 50 in slot 31, elastic component 50 can be the spring of cylindrical spring or other shapes, also can be have flexible pad, and described elastic component 50 one end is resisted against bottom slot 31, the other end be resisted against on snap ring 40.Described snap ring 40 is put together by some block-shaped, that size is identical cards 41, and when some pieces of cards 41 split is snap ring 40, chuck 42 is formed at the top of snap ring 40 inwall, the pulling-preventing mechanism be made up of some saw-tooth rings 43 is formed at the bottom of snap ring 40 inwall, the matching form of the shape of described chuck 42 and the junction of connection-peg 221 and Plug Division 222 is fitted, saw-tooth ring 43 reality forms hangnail, this pulling-preventing mechanism is used for preventing connection-peg 221 from departing from from snap ring 40, and described joint ring 32 is spirally connected with slot 31.More preferably, card 41 has 4, identical and fan-shaped in 90 ° of the shape size of every sheet.
In sum, it is high that the utility model has stock utilization, do not need welding just can make to be connected between stake with stake, and easy to connect, junction resistance to corrosion is strong, is connected firmly, the advantages such as long service life.
Above-described embodiment is used for explaining and the utility model is described, instead of limits this aspect, and in the protection domain of spirit of the present utility model and claim, any amendment make this aspect and change, all fall into protection domain of the present utility model.
