Abstract
The utility model provides a pre-tensioned inequilateral prestressed concrete centrifugal square pile, and is characterized in that the square pile is a hollow structure, and an external outline of a cross-section of the square pile is an inequilateral hexagon. The inequilateral hexagon comprises four symmetrical long sides and two symmetrical short sides. The hollow part of the square pile is round. Concrete provided with multiple reinforcing steel bars is filled between the hollow part and the external outline of the square pile. The utility model has the following effects that: according to the pre-tensioned inequilateral prestressed concrete centrifugal square pile, the external outline comprises four symmetrical long sides and two symmetrical short sides, so that the appearance is artistic, and the pre-tensioned inequilateral prestressed concrete centrifugal square pile has the following advantages that: the construction damage rate is greatly reduced, and the bearing capacity of the single pile is remarkably improved, so that the construction period is shortened; a production process and production of a mould are relatively simple; a contact surface of a pile material and a soil layer is increased, and the friction is increased; a reinforcement manner is flexible, raw materials are saved, and the production cost is reduced.
Description
Technical field
The utility model relates to foundation construction technology in the civil works, especially a kind of pre-tensioning system inequilateral novel prefabricated concrete side's stake.
Background technology
Piling as the foundation pile engineering is more on market, if any pile tube, all kinds of side stake, castinplace pile, drilled pile etc.These pilings mainly divide non-prestressed member and prestressed member two big classes.The prestressed member piling comprises, pile tube, centrifugal prestress square pile etc.Their shortcoming is that the fragility of performance stake is bigger, and shorter from the time to rupture that ftractures, pile body ductility is relatively poor.Non-prestressed member stake comprises, traditional side's stake, tube-sinking cast-in-situ pile etc.It is relatively low to show as bearing capacity of single pile, and bending resistance (drawing) shear behavior is poor, long construction period, and pile quality does not meet designing requirement; Piling well damage in transportation and the use causes the pile concrete durability bad.The preformed pile smooth in appearance, the frictional force of piling and soil layer is little.Also there be a kind of end that the prestressed centrifugally concrete square pile of end plate is arranged, from heavy and light, material-saving, lifting, convenient transportation, bearing capacity of pile is big.But its main muscle layout is reasonable inadequately, and is poor as main muscle, pile body anti-bending strength with prestressed reinforcement or plain bars.End plate four limits do not have the welding groove, have influenced the pile connectivity robustness.The pile body cross section is a quadrangle, and pile body very easily damages for four jiaos in the building operations, causes whole stake to be scrapped, and not only causes waste, but also can influence construction speed.
Summary of the invention
To structural deficiency in the prior art, the purpose of the utility model provides a kind of pre-tensioning system inequilateral novel prefabricated concrete side's stake, reduces the construction breakage rate, improves bearing capacity of single pile, has shortened construction period; Production technology and Mold Making are simple relatively; Increase the contact surface of piling and soil layer, increased frictional force; Reinforcement manner is flexible, has reduced cost of production.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts provides a kind of pre-tensioning system inequilateral shape prestress concrete offcenter squared pile, and wherein: this side's stake is a hollow-core construction, and the outline of said side's stake cross section is the inequilateral hexagon.
Said inequilateral hexagon comprises four long limits and two symmetrical minor faces of symmetry.
The hollow parts of said side's stake is rounded.
Be filled with the concrete that many reinforcing bars are set between the hollow and outline of said side's stake.
The effect of the utility model is a pre-tensioning system inequilateral shape prestress concrete offcenter squared pile; Its outline has four long limits and two minor faces of symmetry, and appearance and modeling is attractive in appearance, and has following advantage concurrently: the construction breakage rate reduces greatly; Bearing capacity of single pile is significantly improved, and makes construction period shorten; Production technology and Mold Making are simple relatively; Increase the contact surface of piling and soil layer, increased frictional force; Reinforcement manner is flexible, saves raw material, has reduced cost of production.

The specific embodiment
In conjunction with accompanying drawing and embodiment the pre-tensioning system inequilateral shape prestress concrete offcenter squared pile of the utility model is explained.
The pre-tensioning system inequilateral shape prestress concrete offcenter squared pile of the utility model, this side's stake is a hollow-core construction, the outline of said side's stake cross section is the inequilateral hexagon.
Said inequilateral hexagon comprises four long limits and two symmetrical minor faces of symmetry, and the hollow parts of said side's stake is rounded.Be filled with the concrete that many reinforcing bars are set between the hollow and outline of said side's stake.
Like Fig. 1, shown in Figure 2, the pre-tensioning system inequilateral shape prestress concrete offcenter squared pile 1 of the utility model is a hollow-core construction, and its hollow parts 2 is rounded, and the outline 3 of cross section is the inequilateral hexagon.This inequilateral hexagon comprises four long limits and two symmetrical minor faces of symmetry.
In addition, the pre-tensioning system inequilateral shape prestress concrete offcenter squared pile 1 of the utility model in use, hollow 2 and outline 3 between be filled with the concrete 5 that many reinforcing bars 4 are set, wherein the quantity of reinforcing bar 4 and diameter are laid with stake type different needs allotment.
The pre-tensioning system inequilateral shape prestress concrete offcenter squared pile of the utility model; Outline has four long limits and two minor faces of symmetry, and appearance and modeling is attractive in appearance, and has following advantage concurrently: the construction breakage rate reduces greatly; Bearing capacity of single pile is significantly improved, and makes construction period shorten; Production technology and Mold Making are simple relatively; Increase the contact surface of piling and soil layer, increased frictional force; Reinforcement manner is flexible, saves raw material, has reduced cost of production.
