Abstract
The utility model discloses a hollow corner cut stake of part prestressing force, including the concrete pile body, set up the steel reinforcement cage in the concrete pile body to and be located the end plate and the skirt skin at concrete pile body both ends, the pile body is provided with the pile body hole, the octagon of cross section for having four minor faces on four the long limits of concrete pile body, the rectangle of cross section for having the arc angle of steel reinforcement cage sets up a prestressing tendons and non - prestressing tendons in every arc angle, prestressing tendons and non - prestressing tendons contact each other. The utility model has the advantages of manufacturing method is simple, the preparation is efficient, and the cloth muscle is even in non - circle stake, and physical properties is good.
Description
Technical field
The utility model belongs to concrete prefabricated product field, the hollow corner cut stake of especially a kind of partial prestressing.
Background technology
Existing PHC pile tube intensity is higher, but is presstressed reinforcing steel due to the main muscle of inside, and fragility is large, and easily damage, and the tensile capacity of non-prestressing tendon and shear resistance capacity do not improve, pile body easily produces crack.Technician devises two kinds of partial prestressing cloth muscle schemes for this reason.The first is that presstressed reinforcing steel and non-prestressing tendon are arranged at interval on the same axis, and the second is that presstressed reinforcing steel and non-prestressing tendon are separately positioned on different reinforcing cages.
But existing arrangement of reinforcement scheme also exists problem, the manufacturing process more complicated of first scheme, operating efficiency is very low, the first scheme be only applicable to circle stake, in not rounded stake its to there is cloth muscle uneven, cause the problem of physical property difference.
Utility model content
Utility model object: provide a kind of partial prestressing hollow corner cut stake, to solve the problems referred to above that prior art exists.
Technical scheme: the hollow corner cut stake of a kind of partial prestressing, comprises concrete pile body, the reinforcing cage be arranged in concrete pile body, and is positioned at end plate and the skirt skin at concrete pile body two ends, and described pile body is provided with pile body hole; The cross section of described concrete pile body is the octagon with four minor faces in four long limits, the cross section of described reinforcing cage is the rectangle with arc angle, each arc angle is arranged a presstressed reinforcing steel and non-prestressing tendon, described presstressed reinforcing steel and non-prestressing tendon contact with each other.
In a further embodiment, described reinforcing cage comprises the presstressed reinforcing steel and non-prestressing tendon that longitudinally run through pile body, be positioned at pile body two ends, anchor rib that length is less than pile body length 1/2, be wound in the stirrup of presstressed reinforcing steel and non-prestressing tendon periphery, and be positioned at the erection hoop reinforcement inside presstressed reinforcing steel and non-prestressing tendon.Every bar limit of described reinforcing cage is provided with one group of presstressed reinforcing steel and non-prestressing tendon, and two groups of anchor ribs, anchor rib is symmetrically distributed in presstressed reinforcing steel and non-prestressing tendon both sides.Every bar limit of described reinforcing cage is provided with a presstressed reinforcing steel and two anchor ribs, anchor rib is symmetrically distributed in presstressed reinforcing steel both sides.Every bar limit of described reinforcing cage is provided with two non-prestressing tendons, and the presstressed reinforcing steel contacted with each other and anchor rib.The length of described minor face is 1/1 to three/6th of long limit.
Beneficial effect: the utility model has the advantage that preparation method is simple, preparation efficiency is high, and in not rounded stake, cloth muscle is even, good physical performance.

Detailed description of the invention
As shown in Figure 1 to Figure 3, the hollow corner cut stake of partial prestressing of the present utility model mainly comprises concrete pile body 1, the reinforcing cage be arranged in concrete pile body, and is positioned at end plate and the skirt skin at concrete pile body two ends, and described pile body is provided with pile body hole 7; The cross section of described concrete pile body is the octagon with four minor faces in four long limits, described reinforcing cage comprises the presstressed reinforcing steel 41 and non-prestressing tendon 42 that longitudinally run through pile body, be positioned at pile body two ends, anchor rib 3 that length is less than pile body length 1/2, be wound in the stirrup 5 of presstressed reinforcing steel and non-prestressing tendon periphery, and be positioned at the erection hoop reinforcement 6 inside presstressed reinforcing steel and non-prestressing tendon; The cross section of described reinforcing cage is the rectangle with arc angle, and each arc angle is arranged one group of presstressed reinforcing steel and non-prestressing tendon, described presstressed reinforcing steel and non-prestressing tendon contact with each other.
As shown in Figure 1, every bar limit of described reinforcing cage is provided with one group of presstressed reinforcing steel and non-prestressing tendon, and two groups of anchor ribs, anchor rib is symmetrically distributed in presstressed reinforcing steel and non-prestressing tendon both sides.
As shown in Figure 2, every bar limit of described reinforcing cage is provided with a presstressed reinforcing steel and two anchor ribs, anchor rib is symmetrically distributed in presstressed reinforcing steel both sides.
As shown in Figure 3, every bar limit of described reinforcing cage is provided with two non-prestressing tendons, and the presstressed reinforcing steel contacted with each other and anchor rib.The length of described minor face 2 is 1/1 to three/6th of long limit.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple equivalents to the technical solution of the utility model, these equivalents all belong to protection domain of the present utility model.
It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
