Abstract

The utility model provides a novel concrete pile that contains mixed reinforcement, concrete pile, the cross-section of stake is along the vertical mixed reinforcement that sets up, and mixed reinforcement includes HRB600 reinforcing bar or below 1230 level prestressing force screw steel bar along the cross-section evenly distributed of stake, distributes 1420 level rod steel between two adjacent HRB600 reinforcing bars or between two adjacent below 1230 level prestressing force screw steel bars. In the concrete pile, the steel bar is not tensioned through tensioning the HRB600 steel bar with good ductility or the prestressed twisted steel bar below 1230 grade, so that the ductility is increased on the whole, the strength of the steel bar can be better exerted in the later stage, and the bending resistance bearing capacity is increased.

Description

Novel concrete pile containing mixed reinforcing bars

Technical Field

The utility model belongs to the technical field of the tubular pile is strutted, especially, relate to a novel concrete pile who contains mixed arrangement of reinforcement.

Background

Because the steel bar has very high strength, the existing prestressed concrete pipe pile is usually realized by adopting a steel bar stretching mode during reinforcement, and although the requirement on strength is met, the steel bar is often not enough in ductility.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel concrete pile who contains mixed arrangement of reinforcement.

Based on the above-mentioned purpose, the utility model discloses take following technical scheme:

the utility model provides a novel concrete pile that contains mixed reinforcement, concrete pile, the vertical mixed reinforcement that sets up in the cross-section of stake, mixed reinforcement includes HRB600 reinforcing bar or below 1230 level prestressing force screw steel bar along the cross-section evenly distributed of tubular pile, distributes 1420 level rod steel between two adjacent HRB600 reinforcing bars or between two adjacent below 1230 level prestressing force screw steel bar.

The stake is the tubular pile, and mixes the arrangement of reinforcement and be circular distribution along the cross-section of tubular pile.

The pile is a hollow square pile, and the mixed reinforcement bars are distributed in a square shape along the cross section of the square pile.

The nominal diameter of the reinforcing bar is 10 mm-14 mm, the side length of the hollow square pile is 400 mm-800 mm,

the minimum wall thickness is 95 mm-110 mm.

The nominal diameter of the reinforcing bar is 10 mm-14 mm, the outer diameter of the concrete pipe pile is 400 mm-1200 mm, the inner diameter is 210 mm-900 mm, and the wall thickness is 95 mm-150 mm.

Compared with the prior art, the utility model has the advantages of it is following:

in the concrete pile, the HRB600 steel bars or prestressed twisted steel bars with good tensile ductility are tensioned, the steel bars are not tensioned, the ductility is increased on the whole, the strength of the steel bars can be better exerted in the later period, and the bending resistance bearing capacity is increased; compared with the single steel bar, the steel bar has the advantages that the bending resistance bearing capacity is increased, and the ductility can be improved by about 50 percent.

Drawings

FIG. 1 is a schematic structural view of example 1;

FIG. 2 is a schematic structural view of example 2.

Detailed Description

Example 1

As shown in fig. 1, the novel concrete pile containing mixed reinforcement comprises a concrete pipe pile 1, wherein the mixed reinforcement is arranged on the side wall of the pipe pile 1 along the moving direction of the pipe pile, the mixed reinforcement comprises HRB600 steel bars 3 uniformly distributed on the side wall of the pipe pile 1, and 1420-level steel bars 2 are distributed between two adjacent HRB600 steel bars 3. The nominal diameter of the reinforcing bar is 10 mm-14 mm, the outer diameter of the concrete pipe pile is 400 mm-1200 mm, the inner diameter is 210 mm-900 mm, and the wall thickness is 95 mm-150 mm.

In the use, stretch-draw good HRB600 reinforcing bar of ductility or prestressing force twisted steel, not stretch-draw the steel bar, because HRB600 reinforcing bar or prestressing force twisted steel have good ductility, this novel concrete pipe pile when increasing ductility on the whole, the intensity of later stage still can better performance steel bar, and the bending resistance bearing capacity increases.

Example 2

The difference from the embodiment 1 is that the concrete pile is a concrete hollow square pile, the side length is 400 mm-800 mm, the minimum wall thickness is 95 mm-110 mm, and the specific structure is shown in fig. 2. The rest is the same as in example 1.
