Abstract
The utility model discloses a concrete pile, belonging to the foundation of a concrete pile. The cross section of the concrete pile is a positive unequal-sided shape formed from three identical circle arc-shaped sections with 1/6 circumferences connected together in sequence or three identical circle arc-shaped segments with 1/6 circumferences and three identical short straight line segments being in sequence connected together at intervals. Corresponding center of a circle of each circle arc-shaped segment is positioned outside the concrete pile, the corresponding diameter of a circle is generally 250-500 mm, and the length of each straight line segment is generally 25-60 mm. Under the condition that the volume of concrete of the concrete pile is identical to the volume of the pile body of a pile with a square, or circular, or a triangular cross section, the bearing capacity of the concrete pile can be obtained; meanwhile, the operation is comparative convenient.
Description
The utility model belongs to concrete pile foundation.
Square and the circular cross-section stake for normally used concrete, the utilization rate of its pile shaft material intensity (ratio of the vertical load that the pile body of the pile capacity of native supporting force decision and the decision of pile shaft material intensity can bear) is often lower, thereby has caused the waste of pile shaft material.
In order to improve the utilization rate of pile shaft material intensity, existing people designs concrete triangular-section preformed pile and hollow section stake.But the pile shaft material rate of utilization of strength of triangular-section preformed pile is still not too high, and the system of hollow section stake is established then cumbersome.
The purpose of this utility model is a kind of concrete pile of design, under the pile body concrete square amount same case of this stake and common square and circular cross-section stake and triangular-section stake, can obtain higher capacity, the utilization rate of pile shaft material intensity is higher, thereby the cost of pile foundation engineering is minimized, and the system of simultaneously this stake is established also more convenient.
Design scheme of the present utility model is a concrete odd-shaped cross-section pile, the pile body cross section of this stake is the just different limit shape that the arc section by three 1/6 identical circumference is connected in sequence, or for fear of the stress concentration phenomenon, the pile body cross section is the just different limit shape that is connected in sequence by the arc section of three the 1/6 identical circumference short lines spacer segment identical with three.The center of circle of arc section correspondence is positioned at outside the cross section, and its corresponding circular diameter is generally 250～500mm.The length of straightway is generally 25～60mm.Pile body is joined main muscle and is positioned at three bights, and auxilliary muscle adopts the Y word shape or adopts the triangle closed stirrup.This stake can be a preformed pile, also can be in situ pile.When being in situ pile, pile body also can be unworthy of reinforcing bar.
The concrete pile that the utility model is designed, in the pile body cross-sectional area of and circular cross-section stake and triangular-section stake square and stake appearance with common concrete with under the situation of (also being that pile body concrete square amount is identical), because its cross-sectional circumference value is bigger, so can obtain higher frictional resistance, also can obtain higher capacity, the utilization rate of pile shaft material intensity is higher, thereby has reduced the cost of Foundation Design.Simultaneously, the second moment of area of this stake is bigger, and bending rigidity is higher.In addition, the system of this stake is established also more convenient.
Accompanying drawing has been described two embodiment of the present utility model.
The reinforced concrete pile elevation of the just different limit shape that Fig. 1 is made up of three identical arc sections for the cross section.
Fig. 2 is the I-I sectional drawing among Fig. 1.
The reinforced concrete pile elevation of the just different limit shape that Fig. 3 is made up of three identical arc sections and three identical straightways for the cross section.
Fig. 4 is the II-II sectional drawing among Fig. 3.
In the accompanying drawing, the arc section of sequence number 1 expression 1/6 circumference, its corresponding center of circle O is positioned at outside the cross section, sequence number 2 expression concrete, sequence number 3 and 4 is represented cage of reinforcement respectively, sequence number 5 expression short lines sections.
Claims (2)
1, concrete pile is characterized in that: the pile body cross section is the just different limit shape that the arc section by four identical quarter turns is connected in sequence, and the center of circle of arc section correspondence is positioned at outside the cross section.
2, according to the concrete pile of claim 1, it is characterized in that: connect by a short lines section between per two adjacent circular arc segments.
