Abstract
The utility model discloses an improved concrete hollow rounded triangular pile which comprises a steel reinforced cage and concrete. The concrete is distributed on the inner side and the outer side of the steel reinforced cage, and the steel reinforced cage is composed of main reinforcement ribs and stirrups. The main reinforcement ribs are distributed in the shape of a rounded triangle, and the stirrups are continuously welded on the main reinforcement ribs in a spiral shape. The number of the main reinforcement ribs is six, and the main reinforcement ribs are respectively arranged on three vertices of the triangle and three middle points of three sides of the triangle, the three main reinforcement ribs on the three vertices of the triangle are prestressed steel reinforcement ribs, and the main reinforcement ribs on the three middle points of the three sides are noprestressed steel reinforcement ribs. The main reinforcement ribs are steel strands or steel bars, and central through holes penetrating through the whole concrete hollow rounded triangular pile along a vertical axial direction are arranged on the concrete hollow rounded triangular pile. Due to the adoption of the nonprestressed steel reinforcement ribs and the adoption of the prestressed steel reinforcement ribs, the improved concrete hollow rounded triangular pile combines the advantages of the prestressed components and the nonprestressed components together.
Description
Technical field
The utility model belongs to building field, relates to the improvement of foundation pile shape and structure in the building field, is a kind of modified concrete hollow fillet triangular pile specifically.
Background technology
The building materials of foundation pile engineering are more on market, if any pile tube, all kinds of square pile, castinplace pile, drilled pile etc.These pilings mainly are divided into non-prestressed member and prestressed member two large classes.Non-prestressed member mainly comprises traditional square pile, 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 are poor, long construction period, and pile quality does not meet designing requirement.The prestressed member piling comprises, pile tube, centrifugal prestress square pile etc.Their shortcoming is, often fragility is larger, and is shorter from the cracking to the time to rupture, and pile body ductility is relatively poor, causes the moment building collapsing when earthquake occurs, and makes that personnel do not have the sufficient time escape in the building.This problem is particularly outstanding in many shakes area such as Japan, Taiwan, China.Before, most of prefabricated pilings mostly are non-prestressed or prestressing force, and above-mentioned shortcoming is difficult to avoid.
Existing concrete prefabricated units cross section is various, and many on the market is square and circular cross-section, and when conduct carrying effect member, its maximum purpose is to improve the pile body bearing capacity that unit materials can provide, thereby economical with materials reduces cost.The very large characteristics of preformed pile are a side and soil interaction, utilize the frictional force between stake and the soil to improve pile body bearing capacity.
Relative and the section ratio surface area less of circular cross-section is not so take advantage at pile tube aspect the raising stake side-friction force; Square pile and soil body frictional force are larger, and the bearing capacity ratio pile tube is good, but solid square pile is heavy, feed consumption is many; Hollow square pile combines the advantage of pile tube and square pile preferably, and outer cross section is square, and interior cross section is circular, can improve a side-friction force comparatively speaking, but its cross section concrete thickness differs, and the frictional force of unit volume material also is not fully exerted.
In the recent period, special-shaped triangular pile also occurs, but arrangement of reinforcement owes slightly rationally, pile body globality, shearing resistance bending resistance resistance to tension and increase Material ductility when earthquake disaster occurs, increase the aspects such as escape time and have much room for improvement.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to be to provide a kind of modified concrete hollow fillet triangular pile, few, the material-saving of building loss, from the characteristics of heavy and light.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of modified concrete hollow fillet triangular pile, comprise reinforcing cage, concrete, concrete is distributed in the inside and outside both sides of reinforcing cage, and described reinforcing cage is made of main muscle, stirrup, main muscle is the fillet Triangle-Profile, and what stirrup was continuous in the shape of a spiral is welded on the main muscle.
Described main muscle is 6, lays respectively on the mid point on leg-of-mutton 3 fillets of fillet and three limits, and 3 main muscle that are positioned at the fillet place are prestressed reinforcement, and the main muscle that is positioned on the three limit mid points is nonprestressed reinforcement.
Described main muscle is steel strand or rod iron.
Described concrete hollow fillet triangular pile y direction is provided with the central through hole that runs through whole concrete hollow fillet triangular pile, interior all cross sections of described concrete hollow fillet triangular pile are circular, the periphery cross section of described concrete hollow fillet triangular pile also is the fillet triangle, and described concrete hollow fillet triangular pile is identical in the interior periphery cross section geometry of whole y direction.
By technique scheme, the application's beneficial effect is:
Both adopted nonprestressed reinforcement, adopted again prestressed reinforcement, in conjunction with the common advantage of prestressing force and non-prestressed member.
Because, a kind of modified concrete hollow of the utility model fillet triangular pile, week is circular in its cross section, periphery is the fillet triangle, effectively raise the specific area of material, can make unit materials have larger surface area, thereby the stake side-friction force of raising preformed pile is to improve bearing capacity of single pile.
Because, a kind of modified concrete hollow of the utility model fillet triangular pile, week is circular in its cross section, periphery is the fillet triangle, its corner is stress and eliminates circular arc, so the utility model can effectively eliminate stress concentrated, can effectively improve construction pile rate in the pile foundation construction process.
Because week is circular in a kind of modified concrete hollow of the utility model fillet triangular pile, its cross section, periphery is the fillet triangle, and its corner is stress and eliminates circular arc; Main muscle layout triangular in shape, on structure, the utility model master muscle is rationally distributed, stirrup is being welded in the shape of a spiral for reinforcing cage, and because having increased main muscle quantity, pile capacity is large, the bending resistance shear behavior is good, shock resistance is strong so that the utility model becomes with respect to like product before.
