Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a PHC pile having a shear reinforcement plate,

The present invention relates to a PHC file equipped with a shear reinforcement plate and a structure using the same. More specifically, the present invention relates to a PHC pile equipped with a shear reinforcement plate that can be effectively used for shear reinforcement and connection to a horizontal member when used as a foundation or a ground structure (such as a wall, a column, or a roof) .

Conventionally, a file basis for a structure used as a deep foundation can be roughly divided into a steel pipe file and a PHC file (a centrifugal force high-strength concrete file of a pretension type)

In these files, there is no significant difference in terms of end bearing capacity with respect to the same diameter, but in particular, resistance to bending or shearing is very different in files, It was decided whether or not to apply it.

That is, the PHC file has no problem in applying the PHC file because it has a comparative advantage in terms of workability as well as being economical in a structure having a large vertical force as compared with a steel pipe file. However,

In the case of a structure having a large influence of the horizontal force (shear force) and the bending moment such as earth pressure and seismic load, the PHC file has a low resistance to such a problem, and therefore, there is a problem in that it is inevitable to use a relatively expensive steel pipe file.

Therefore, a synthetic PHC file has been introduced in order to improve the structural performance of the file in a simple and economical manner, while allowing the structural performance of a conventional PHC file to be inherently used.

That is, as shown in FIG. 1A, the mold 20 for a PHC file is first disposed on a production stand (not shown), and the internal stiffener 10 is disposed inside the mold 20. The internal stiffener 10 is a steel bar 11 and a spiral reinforcing bar 12 used in a conventional PHC file.

Since the steel rods 11 are installed with a large number of mutually spaced apart from each other inside the mold 20 so as to introduce a tensile force (longitudinal direction), the steel rods 11 are bonded to the steel rods 11, And is a reinforcing bar which is installed while wrapping the steel bar 11 in a spiral shape.

At this time, the shear connector 13 is installed so as to extend and protrude toward the hollow portion S of the PHC file to be completed while enclosing the internal stiffener 10.

The shear connection member 13 is formed in the shape of a closed-loop type of closed-loop reinforcing bars, for example, in such a manner that the steel rods 11 and the spiral reinforcing bars 12 are crossed with each other so as to be installed laterally in a cross- . The shear connectors 13 are installed at a predetermined distance from the internal stiffener 10.

After the internal stiffener 10 and the shear connection member 13 are disposed in the mold 20, the concrete C is introduced into the mold 20, and the concrete C is transferred to the concrete pile 30 itself Respectively.

Next, as shown in FIG. 1B, the mold 20 is rotated so that the concrete C injected by the centrifugal force can be formed with a predetermined thickness from the inner side of the mold 20 so that the charged concrete C is hardened The concrete pile portion 30 can be naturally manufactured in the form of a hollow tube.

Next, as shown in FIG. 1C, after the concrete pile 30 is formed by curing the inserted concrete C, the mold 20 is demolded so that the PHC pile production can be completed in the factory.

As a result, it can be seen that the synthetic PHC file for improving the structural performance of the conventional PHC file follows the scheme of installing the front end connector 13 further.

However, in the case of the front end connector 13 used for reinforcing the conventional PHC file, although it is useful for the structural reinforcement of the PHC file, it is necessary to construct the ground structure as well as the foundation of the structure, PHC files with complex functions that can resist stresses have not yet been introduced.

Accordingly, the present invention can provide a PHC file that can flexibly and shearly reinforce a desired site with a high degree of freedom, and can also form a limited amount of in-filled concrete. Also, in a PHC file exposed to the ground, The present invention also provides a PHC pile equipped with a highly efficient shear reinforcement plate and a structure using the same.

In order to achieve the above object,

First, in the PHC file, a shear reinforcement plate is installed in advance so that a desired portion of the PHC file can be reinforced by shearing.

The shear reinforcement plate is formed integrally with the hollow concrete of the PHC pile using a partial shear reinforcement plate in the form of a ring so as to replace the conventional shear reinforcement. In a portion where structural reinforcement is required, So that shear reinforcement is advantageous.

In addition, the shear reinforcement plate is formed integrally with the hollow concrete of the PHC pile using a front shear reinforcement plate in the form of a horizontal plate so that it can be replaced with a conventional shear reinforcement. In a portion where structural reinforcement is required, So that shear reinforcement is advantageous.

Since the front shear reinforcement plate is in the form of a horizontal plate, the upper portion of the installation portion can serve to fill the concretion concrete.

Second, the PHC file formed with the above-mentioned shear reinforcement plate can be used as a foundation file of a structure but also extended to the ground so that it can be used as a structural wall, a column, or a porthole (ground structure) A connecting bracket and a fixing member are provided so as to effectively resist local stress acting on the region.

Third, the PHC file with the shear reinforcement plate can be used as a non-fastening structure by using it for underground longitudinal structure construction. At this time, it is possible to introduce the prestress using the shear reinforcement plate.

The shear reinforcement plate according to the present invention can effectively reinforce a desired portion of the PCH file, can separate the inner filled concrete, and can effectively reinforce the connection portion with the horizontal member in the construction of the ground structure. Effective PHC file can be used.

That is, the shear reinforcement plate 130 of the present invention basically has a function of replacing the role of the conventional spiral reinforcing bars in the PHC file.

That is, the conventional spiral reinforcing bar has a role of wrapping and fastening the steel rods. Since the steel reinforcing bars are also penetrated through the shear reinforcing plate 130, the steel rods can be constrained. In the case of the conventional spiral reinforcing bars, The shear reinforcement plate 130 is in the form of a horizontal plate, which can effectively resist the horizontal force, and can be installed on a mold during PHC file production, which is very efficient.

The shear reinforcement plate 130 includes a partial shear reinforcement plate 131 formed in a shape of a ring occupying a part of the hollow portion S to be embedded in the concrete pile portion 110,

And a front shear reinforcement plate 132 in the form of a horizontal plate for closing the hollow portion S by embedding an outer frame portion in the concrete pile portion 110.

That is, the partial shear reinforcement plate 131 is formed in a ring shape so that the inner diameter and the hollow portion S have the same diameter, and the outer diameter is formed to be slightly smaller than the diameter of the concrete pile 110, When the plate 131 is installed, the hollow portion S is not blocked.

The partial shear reinforcement plate 131 is provided with a steel rod hole h1 for allowing the steel rod 121 to pass therethrough. In particular, the axial reinforcement 123 (a kind of internal reinforcement) And the reinforcing holes h2 are formed spaced apart from each other.

The partial shear reinforcement plate 131 is embedded in the concrete pile 110 before the PHC pile is manufactured, and a plurality of partial shear reinforcement plates 131 are installed at desired locations to partially reinforce the PHC pile.

Here, the axial reinforcing steel (123, an internal reinforcing member) is intended to more effectively resist the bending moment acting on the PHC pile as an axial reinforcing bar, and such axial reinforcing steel reinforcing bars 123 are disposed .

Next, the front shear reinforcement plate 132 is formed in the form of a horizontal plate so as to close the concrete pile 110 and the hollow portion S by the underfill concrete C.

In addition, the front shear reinforcement plate 132 is formed with a steel bar hole h1 so that the steel bar 121 can pass therethrough. In particular, the axial reinforcement bar 123 (a kind of internal reinforcement) And the reinforcing steel holes h2 are formed spaced apart from each other.

The front shear reinforcement plate 132 is also embedded in the concrete pile 110 before the PHC pile is manufactured so that a plurality of the front shear reinforcement plates 132 can be partially installed at desired locations to partially reinforce the PHC pile.

Accordingly, the front shear reinforcement plate 132 is filled with the hollow portion of the PHC pile so that the filled concrete C is filled above the portion where the front shear reinforcement plate 132 is installed, thereby filling the hollow portion of the PHC pile with concrete . This is especially useful in areas where horizontal shear forces are large in the PHC file.

The partial and total shear reinforcement plates 131 and 132 may be combined or individually provided at desired portions and the spiral reinforcing bars 122 are not provided at the portions where the shear reinforcement plates 131 and 132 are installed .
