Abstract

The utility model discloses a concrete tubular pile. The concrete tubular pile comprises a concrete tube (1), a pile shoe and a pile cap. The concrete tube (1) is square and formed by wrapping concrete around steel bars, and the center of the concrete tube (1) is an inner round hole (1-2). The pile shoe is composed of a pile shoe core (2-1), a pile shoe body (2-2) and a pile shoe point (2-3). The pile shoe is arranged at the bottom end of the concrete tube (1). The pile shoe core (2-1) is arranged inside the inner round hole (1-2). The pile cap is composed of a pile cap top (3-1) and a pile cap edge (3-2). The pile cap top (3-1) is arranged at the top end of the concrete tube (1), and the pile cap edge (3-2) is clamped outside the concrete tube (1). The concrete tubular pile is high in concrete strength and bearing capacity, large in rigidity, small in component deformation, light in weight, convenient to construct, small in dead weight and convenient to transport, the production condition is simple, and concrete can be saved by 30-50 percent.

Description

A kind of concrete tubular pile

Technical field

The utility model relates to a kind of building foundation pile, specifically a kind of concrete tubular pile.

Background technology

The pile foundation of at present China's building trade employing roughly is divided into preformed pile and castinplace pile; Preformed pile divides concrete pile and piling bar; Concrete pile is divided into again pipe stake and solid square pile; In the cast-in-situ concrete epoch of fat beams and columns, these stakes are very practical.Along with the development of China's Building technology, building is made batch production, component parts lightness trend more and more obvious, the requirement for bearing capacity of pile foundation also can be more and more lower.In order to adapt to the development of this form, adopt the Novel pile basis more and more necessary.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of concrete tubular pile, and supporting capacity is strong, and rigidity is large, and part distortion is little, and quality is light, the constructability transportation, and working condition is simple, can save concrete 30%-50%.

To achieve these goals, a kind of concrete tubular pile of the utility model comprises concrete pipe, shoe and pile cover, and concrete pipe is square, formed by concrete parcel reinforcing bar, the center is interior circular hole, and shoe is comprised of shoe core, shoe body and shoe point, and the concrete pipe bottom arranges shoe, the shoe core is positioned at circular hole, pile cover is comprised of pile cover top and pile cover limit, and the pile cover overhead is in the concrete pipe top, and the pile cover checkpost is outside concrete pipe.

The length of concrete pipe is 3-6 rice, and the diameter of interior circular hole is the 120-180 millimeter.

The height of shoe core is 100 millimeters, and diameter is less 10 millimeters than the diameter of interior circular hole, and the diameter of shoe body is the 300-400 millimeter, and the shell portion height is the 200-300 millimeter, 200 millimeters of the height of shoe point.

Pile cover is formed by the densified wood engraving, pile cover top thickness degree 40-50 millimeter, and pile cover limit thickness 40-50 millimeter, the gap between pile cover limit and the concrete pipe is the 10-20 millimeter.

The utility model concrete strength is high, and supporting capacity is strong, and rigidity is large, and part distortion is little, and quality is light, constructability, and it is little to conduct oneself with dignity, and is convenient to transportation; Manufacture easily, working condition is simple, can save concrete 30%-50%.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, concrete pipe, 1-2, interior circular hole, 2-1, shoe core, 2-2, shoe body, 2-3, shoe point, 3-1, pile cover top, 3-2, pile cover limit.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of concrete tubular pile comprises concrete pipe 1, shoe and pile cover, and concrete pipe 1 is square, formed by concrete parcel reinforcing bar, the center is interior circular hole 1-2, and shoe is comprised of shoe core 2-1, shoe body 2-2 and shoe point 2-3, and concrete pipe 1 bottom arranges shoe, shoe core 2-1 is positioned at circular hole 1-2, pile cover is comprised of pile cover top 3-1 and pile cover limit 3-2, and pile cover top 3-1 places concrete pipe 1 top, and pile cover limit 3-2 is stuck in outside the concrete pipe 1.

The length of concrete pipe 1 is 3-6 rice, and the diameter of interior circular hole 1-2 is the 120-180 millimeter.

The height of shoe core 2-1 is 100 millimeters, and diameter is less 10 millimeters than the diameter of interior circular hole 1-2, and the diameter of shoe body 2-2 is the 300-400 millimeter, and the shell portion height is the 200-300 millimeter, 200 millimeters of the height of shoe point 2-3.

Pile cover is formed by the densified wood engraving, pile cover top 3-1 thickness 40-50 millimeter, and pile cover limit 3-2 thickness 40-50 millimeter, the gap between pile cover limit 3-2 and the concrete pipe 1 is the 10-20 millimeter, timber is selected Tan Shu, Chinese scholartree, jujube tree or similar trees.

, with behind the pile tube unwrapping wire location shoe as for the stake position, is placed interior circular hole 1-2 outside the shoe core 2-1 according to designing requirement, pile cover as for concrete pipe 1 top, just can be carried out piling construction.If a joint pile length is inadequate, can pile extension, with the stake hole plug, get final product with continuing piling behind the sulphide mastic pile extension.
