Abstract
The utility model relates to a strong support type pre-stressed concrete square pile. The square pile comprises a concrete pile body with a square cross section, wherein a first supporting steel bar is arranged at the four top corners in the concrete pile body respectively; a supporting steel pipe is embedded with the center of the concrete pile body; a first annular supporting group, a second annular supporting group and a third annular supporting group are arranged in the interior area of the supporting steel pipe from the inside out in sequence; each of the first annular supporting group, the second annular supporting group and the third annular supporting group is provided with four circular arc-shaped steel plates taking the central axis of the supporting steel pipe as a center and distributed rotationally; a second supporting steel bar is arranged in the center of the supporting steel pipe. The strong support type pre-stressed concrete square pile is simple in structure and reasonable in design, as a multilayer radiation type reinforcing design is adopted, the structure of the concrete pile is more solid and reliable, and the square pile is suitable for various kinds of civil engineering construction.
Description
Technical field
The utility model relates to a kind of strong support type prestressed concrete square pile.
Background technology
In known technical field, prestressed concrete, there is too early the phenomenon in crack in order to make up concrete, before member uses (loading), give in advance precompression of concrete, in concrete tensile region, by the method for artificial reinforcing, reinforcing bar is carried out to stretch-draw, utilize the retraction force of reinforcing bar, concrete in tension district is stressed in advance.The precharge pressure that this storage is got off, in the time that member bears by external load generation pulling force, first offsets the precompression in concrete in tension zone, then increase with load, just make concrete in tension, this has just limited concrete elongation, delay or do not make crack occur, this is just called prestressed concrete.In existing civil engineering construction, often need concrete square pile to carry out building of various structures.
Utility model content
The technical problems to be solved in the utility model is: a kind of strong support type prestressed concrete square pile is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of strong support type prestressed concrete square pile, comprise that cross section is foursquare concrete pile body, four drift angle places in described concrete pile body are provided with the first bearing bar respectively, center at described concrete pile body is inlaid with supporting steel pipe, interior zone at described supporting steel pipe is provided with the first annular brace group from outside to inside successively, the second annular brace group and the 3rd annular brace group, and described the first annular brace group, in the second annular brace group and the 3rd annular brace group, all there are four blocks of circular arc steel plates that rotation distributes centered by the central axis of supporting steel pipe, be provided with the second bearing bar at the center of described supporting steel pipe.
Further, as a kind of concrete embodiment, the wall thickness of supporting steel pipe described in the utility model is 4～12mm.
Further, as a kind of concrete embodiment, the diameter of the first bearing bar described in the utility model is 10～40mm, the diameter 5～30mm of described the second bearing bar.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, adopt the reinforcing design of multi-layer radial type, make the structure of concrete square pile more solid and reliable, are applicable in various civil engineering constructions.
