Abstract
The utility model discloses a pre-casting reinforced concrete abnormity section stake, belongs to the building field. The pre-casting reinforced concrete abnormity section stake comprises concretes, a plurality of main bars and a plurality of hoop bars. Section shape of the pre-casting reinforced concrete abnormity section stake is the shape of a crisscross or H-shaped or gear-shaped. Compared with the square stake and pipe stake with the equal section area, the abnormity section stake changes the section geometry mechanics feature, increases the rigidity of the section and side area of the stake to improve the side friction and horizontal loading strength.
Description
Technical field
The utility model relates to a kind of prefabricated reinforced concrete odd-shaped cross-section pile, belongs to building field.
Background technology
The prefabricated reinforced concrete silent piling that present building field is used has square-section (side's stake) and circular hollow cross section (pile tube) by cross sectional shape, also is that application is more at present.But side's stake and pile tube also have weak point, and the shortcoming of side's stake is: because sectional area is not too big, all lateral areas of stake are relatively little, and pile side friction is also relatively little, thereby construction unit is more with stake quantity; The shortcoming of pile tube is: rigidity of section is little, and piling process pile body might ftracture, broken pile, and its pile side friction is also relatively little.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of under the situation of equal sectional area, the prefabricated reinforced concrete odd-shaped cross-section pile that rigidity of section is big, all lateral areas of stake have bigger increase, pile side friction to improve a lot.
The technical solution of the utility model is as follows:
A kind of prefabricated reinforced concrete odd-shaped cross-section pile, this odd-shaped cross-section pile comprise concrete, main muscle, stirrup, and the cross sectional shape of described prefabricated reinforced concrete odd-shaped cross-section pile is " ten " font, or " worker " font, or gear shape.
Above-mentioned prefabricated reinforced concrete odd-shaped cross-section pile, concrete can be ordinary concrete or high-strength concrete.Concrete can add various additives, as reinforcing agent, early strength admixture, water reducing agent, and the flyash of anti-crack fiber goods, instead of part cement.
Above-mentioned prefabricated reinforced concrete odd-shaped cross-section pile, the material of main muscle, stirrup can be plain bars or prestressed reinforcement.The form of reinforcement of main muscle can be single layout, also can arrange more and put.Main muscle and stirrup are good by the colligation of iron wire (not shown), form reinforcing cage.
Advantage of the present utility model and good effect:
Compare with the side's stake and the pile tube of equal sectional area, odd-shaped cross-section pile has changed the geometric mechanics feature in cross section, and rigidity of section is increased, and all lateral areas of stake also have bigger increase simultaneously, thereby pile side friction and horizontal bearing capacity are all improved a lot, can reduce the quantity of construction unit with stake.Compare with side's stake of equal lateral area, equal pile side friction, odd-shaped cross-section pile can reduce concrete materials, plays to alleviate deadweight the purpose of economical with materials.
Therefore, the utility model not only has bigger horizontal bearing capacity, bigger pile side friction at the preformed pile basic field of building silent piling, and also has bigger economic benefit and social benefit.

The specific embodiment
As shown in Figure 1, main muscle 2 is single layout, and main muscle 2 and stirrup 3 are good by the colligation of iron wire (not shown), forms reinforcing cage, and main muscle 2, stirrup 3 can be plain bars or prestressed reinforcement.Behind the concreting 1, promptly form prefabricated reinforced concrete odd-shaped cross-section pile.Concrete 1 can be ordinary concrete or high-strength concrete.Concrete 1 also can add various additives, as reinforcing agent, early strength admixture, water reducing agent, and the flyash of anti-crack fiber goods, instead of part cement.Cross section 4 is " ten " font.
Shown in Figure 3, cross section 4 is " worker " font, and main muscle 2 and stirrup 3 are by the colligation of iron wire (not shown), concreting 1.
Shown in Figure 4, cross section 4 is a gear shape, and main muscle 2 and stirrup 3 are by the colligation of iron wire (not shown), concreting 1.
Claims (3)
1. a prefabricated reinforced concrete odd-shaped cross-section pile comprises concrete, main muscle, stirrup, it is characterized in that, the cross sectional shape of described prefabricated reinforced concrete odd-shaped cross-section pile is " ten " font, or " worker " font, or gear shape.
2. prefabricated reinforced concrete odd-shaped cross-section pile as claimed in claim 1 is characterized in that, described concrete is ordinary concrete or high-strength concrete.
