Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fold-line-shaped pile foundation structure, utilizes broken line structure to offset part foundation level imposed load effect, thereby reduces basic body engineering quantity.
To achieve these goals, the technical solution of the utility model is: a kind of fold-line-shaped pile foundation structure, comprise inclination epimere for connecting superstructure and for buried vertical hypomere, the upper surface of described vertical hypomere is connected with the lower surface of inclination epimere, line between the center, upper surface of the center, upper surface of described inclination epimere and vertically hypomere is broken line, the projection extended line of described broken line on vertical hypomere upper surface and the intersection point of the two junction are break, more than described break is positioned at the anchored end bottom of inclination epimere and superstructure connector and is positioned at vertical hypomere calculating buried depth ground.
Further, described inclination epimere and superstructure adopt stone bolt to be connected, and the slope value of described broken line is not more than horizontal force that superstructure transmission gets off and the ratio of vertical force.
Further, the slope value of described broken line is got horizontal force that superstructure transmission gets off and the ratio of vertical force.
Further, described superstructure is directly extended and is connected with inclination epimere, and the slope value of described broken line is consistent with the slope value of the main material of superstructure.
Further, the horizontal force opposite direction that the incline direction of described broken line and superstructure transmission are got off.
Further, described fold-line-shaped pile foundation is broken at the lengthways main steel bar of 120 degree in planar range of incline direction that epimere disconnects main muscle and hypomere disconnects main muscle, and the main muscle of described disconnection all has the anchorage length at another section.
Further, the radial section of described fold-line-shaped pile foundation is circular.
The utlity model has rational in infrastructure, force path is clear, reduce the advantage such as base specification, is specially adapted to the larger pile foundation of foundation level active force effect.Compared with existing pile foundation structure form, the utility model utilizes broken line structure to offset part foundation level imposed load effect, therefore can adopt the pile foundation pattern of comparison paxilla footpath or smaller buried depth, also make pile foundation structure stress reduce, can reduce the sectional area of basic stress reinforcing bar, thereby reduce basic body engineering quantity.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Detailed description of the invention
As shown in Fig. 1 ~ 4, a kind of fold-line-shaped pile foundation structure, comprise inclination epimere 2 for connecting superstructure and for buried vertical hypomere 1, the upper surface of described vertical hypomere 1 is connected with the lower surface of inclination epimere 2, the upper surface center O of described inclination epimere 2
2(being also superstructure connector center) and vertically the upper surface center O of hypomere 1
1between line be broken line Z, the projection extended line of described broken line Z on vertical hypomere 1 upper surface is break O with the intersection point of the two junction, and described break O is positioned at the anchored end bottom of inclination epimere 2 and superstructure connector and is positioned at more than vertical hypomere 1 calculates buried depth ground.
In the present embodiment, in the time that inclination epimere 2 and superstructure adopt stone bolt to be connected, the slope value of described broken line Z is not more than horizontal force H that superstructure transmission gets off and the ratio of vertical force, and the slope value of described broken line Z can preferentially be got horizontal force H that superstructure transmission gets off and the ratio of vertical force.In the time that the direct extension of superstructure is connected with inclination epimere 2, the slope value of described broken line Z is consistent with the slope value of the main material of superstructure.The horizontal force H opposite direction that the incline direction D of described broken line Z and superstructure transmission are got off.
In the present embodiment, described fold-line-shaped pile foundation is broken at the lengthways main steel bar of 120 degree in planar range of incline direction D that epimere disconnects main muscle 4 and hypomere disconnects main muscle 3, and the main muscle of described disconnection all has the anchorage length at another section.The radial section of described fold-line-shaped pile foundation is circular, but is not limited to this, can also be square etc.
When construction: first determine the position of basis and superstructure connector anchored end bottom, in conjunction with the calculating proud exposure of on-the-spot pile foundation, thus the break O position of definite fold-line-shaped pile foundation; Determine again the slope of the above part of break O (epimere 2 tilts) according to basis and the slope of superstructure connector or the ratio of horizontal force H and vertical force, i.e. the slope of broken line Z; The following part of break O (being vertical hypomere 1) adopts conventional pile foundation construction mode to construct, and the above part employing of break O group mould is cast.Wherein, when the following part of break O is when casting concrete under water, break O partly should adopt secondary to cast pattern above, otherwise can once cast; When adopting secondary to cast pattern, the inner corner trim place reinforcing bar of the above part of break O should be below break O part reserved joint bar.
The utility model utilizes the fold-line-shaped structure of pile foundation to offset the horizontal force that superstructure transmission is got off, thereby meet the horizontal bearing capacity of pile foundation, avoid adopting the long way of increase stake footpath stake, also reduce the use amount of reinforcement foundation, be specially adapted to certain calculating proud exposure, foundation level active force larger pile foundation again.Be arranged on the pile foundation on slope, or on level land, calculate the pile foundation that exposure aspect ratio is larger, all gene basis calculating exposure aspect ratio is larger, and the effect of horizontal applied force is just larger.Under this condition, can adopt fold-line-shaped pile foundation.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
