Abstract

The utility model discloses a prestressed high strength concrete (PHC) pipe core-insert compound pile which comprises a plurality of hollow PHC pipe piles which are arranged in a foundation side by side. Profile steel is inserted in each PHC pipe pile, and concrete wrapping the profile steel is arranged inside each PHC pipe pile. According to the PHC pipe core-insert compound pile, the profile steel is inserted in each PHC pipe pile, the concrete is arranged in the hollow position of each hollow PHC pipe pile to fix the profile steel and enhance the strength of the PHC pipe piles, therefore, the PHC pipe piles have better loading capacity, and the PHC pipe core-insert compound pile is suitable for being used in the field of pile body structures in buildings.

Description

A kind of PHC pipe lock pin combination pile
Technical field
The utility model relates to a kind of building structure, particularly relates to a kind of building pile body structure.
Background technology
In the prior art, prestressed high-strength concrete pile (being called for short the PHC stake) generally is to adopt pretensioned prestressing and centrifugal molding process in professional factory, the uniform section member of a kind of hollow cylinder of making through steam press maintenance, after being transported to the job site, the method by hammering or static pressure sinks to underground basis or supporting and protection structure as building.It has advantages such as vertical bearing capacity of single pile height, speed of application are fast, reliable in quality.Be widely used for industry and various fields such as civilian construction, railroad bridge, port and pier.
But this type bending resistance shear behavior is poor, and the horizontal movement of the soil body easily causes the pile tube fracture, has limited this type to a certain extent and has been applied in the foundation pit supporting project.At present, for improving the anti-horizontal loading ability of prestressed concrete pipe pile, measures such as concrete core are filled in main employing in the engineering, and effect is unsatisfactory.
The utility model content
For addressing the above problem, the utility model provides a kind of PHC pipe lock pin combination pile with better load-carrying ability.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of PHC manages lock pin combination pile, comprises the PHC pile tube of some hollows of arranging side by side in ground, all is inserted with shaped steel in each PHC pile tube, is equipped with in each PHC pile tube to be wrapped in the outer concrete of shaped steel.
Be further used as the improvement of technical solutions of the utility model, the top of PHC pile tube is provided with the stake apical cap beam that connects each PHC pile tube.
Be further used as the improvement of technical solutions of the utility model, linking to each other with each apical cap beam is equipped with an anchor pole that inserts in the ground.
Be further used as the improvement of technical solutions of the utility model, each anchor pole is parallel to each other.
Be further used as the improvement of technical solutions of the utility model, each shaped steel is i iron, and each shaped steel all is parallel to the axis of PHC pile tube and assigns.
The beneficial effects of the utility model: this PHC pipe lock pin combination pile has all plugged shaped steel at the center of each PHC pile tube, and add the intensity that concrete fixes shaped steel and strengthens the PHC pile tube at the hollow position of the PHC of hollow pile tube, can make the PHC pile tube have better load-carrying ability.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model embodiment pile body structural representation;
Fig. 2 is the utility model embodiment pile body structure vertical view.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of PHC pipe lock pin combination pile, comprises the PHC pile tube 1 of some hollows of arranging side by side in ground, all is inserted with shaped steel 2 in each PHC pile tube 1, is equipped with the concrete that is wrapped in outside the shaped steel 2 in each PHC pile tube 1.
This PHC pipe lock pin combination pile has all plugged shaped steel 2 at the center of each PHC pile tube 1, and adds the intensity that concrete fixes shaped steel 2 and strengthens PHC pile tube 1 at the hollow position of the PHC of hollow pile tube 1, can make PHC pile tube 1 have better load-carrying ability.
As the utility model preferred embodiment, the top of PHC pile tube 1 is provided with the stake apical cap beam 3 that connects each PHC pile tube 1.
A plurality of PHC pile tubes side by side can be coupled together by the stake apical cap beam 3 that is arranged on PHC pile tube 1 top, to strengthen its whole supporting capacity.
As the utility model preferred embodiment, link to each other with each apical cap beam 3 and be equipped with an anchor pole 4 that inserts in the ground.
As the utility model preferred embodiment, each anchor pole 4 is parallel to each other.
Each anchor pole 4 that is parallel to each other can make each PHC pile tube 1 have better parallelism, and the supporting capacity of a row PHC pile tube 1 that is arranged in parallel is more excellent.
As the utility model preferred embodiment, each shaped steel 2 is i iron, and each shaped steel 2 all is parallel to the axis of PHC pile tube 1 and assigns.
This PHC pipe lock pin combination pile when constructing, adopt earlier plant equipment with 1 hammering of PHC pile tube or static pressure to projected depth, then shaped steel 2 is inserted PHC pile tubes 1, PHC pile tube 1 in, pour into self-compacting concrete or high-strength concrete.Build an apical cap beam 3 then, adjacent PHC pile tube 1 is linked to each other.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
