Description
Technical field
The utility model relates to a kind of concrete square pile.
Background technology
Pile foundation is made up of jointly foundation pile and the cushion cap being connected to stake top.If pile body is all embedded in soil, cushion cap bottom surface contacts with the soil body, be then called embedded footing on piles, low capped pile foundation; If basset and be positioned at more than ground at the bottom of cushion cap in pile body top, be then called elevated footing on piles.Building pile foundation is generally embedded footing on piles, low capped pile foundation plinth.In highrise building, pile foundation is widely used.
Pile foundation belongs to underground concealed engineering, especially castinplace pile, very easily there is the mass defect of necking down, the folder variforms such as mud, broken pile or sediment be blocked up, affect pile construction integrity and bearing capacity of single pile, therefore supervision of works be must carry out, script holder's record and quality examination seen, to ensure the quality of products, lessen the hidden dangers.For post Single Pile or large-section in-situ concrete pile engineering.
The shearing resistance of existing concrete pile pile body, tensile property and load-carrying properties are general, have buried certain hidden danger to the basis of building high building,
Utility model content
The technical problems to be solved in the utility model is to provide a kind of concrete square pile with outstanding shearing resistance, tensile property and load-carrying properties.
For solving the problem, the utility model adopts following technical scheme:
A kind of concrete square pile, comprise concrete, end plate and bent-up bar, the polishing of described concrete external surface, aluminium alloys box section is provided with in described concrete, the square tube-surface of described aluminium alloys scribbles anticorrosive paint, triangle metal sheet is welded with below described end plate, described bent-up bar one end is welded on triangle metal sheet, the described bent-up bar other end is welded with pile top, described bent-up bar is welded with the first principal rod and the second principal rod, described first principal rod runs through aluminium alloys box section, described first principal rod end is welded with stirrup, described stirrup is provided with one or more, described stirrup and the first principal rod form triangular shape, dowel is welded with between described stirrup, described second principal rod and bent-up bar form right angle trapezoidal.
As preferably, described concrete external surface is coated with anticracking grout, and adhesion strength is high, and weatherability is high, and water-proofing anticracking is effective.
As preferably, the square thickness of pipe wall of described aluminium alloys is 0.8cm.
As preferably, described anticorrosive paint is anti-corrosion polyurethane coating, and antiseptic property is good, weatherability is strong.
As preferably, described first principal rod is provided with one or more.
As preferably, described bent-up bar electroplating surfaces with tin, not only can play good antiseptic effect, but also contributes to welding.
As preferably, described first principal rod and aluminium alloys box section bond, and good integrity gets a promotion, Stability Analysis of Structures.
As preferably, described dowel is longitudinal dowel.
The beneficial effects of the utility model are: by being welded with the first principal rod and the second principal rod on bent-up bar, stirrup and the first principal rod form triangular shape; Second principal rod and bent-up bar form right angle trapezoidal, multiple stress point can be formed, significantly improve the overall bearing capacity of structure, and concrete is identical with aluminium alloys box section Impact direction, and form composite bodies, increase bending resistance and the shear resistance of structure, improve intensity, crack resistance.
