Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-

The present invention relates to a stranded wale which is capable of eccentricity control, a temporary retention structure using the same, and a construction method thereof. More specifically, the present invention relates to a folded wale which can control the eccentricity of a tensional material, and a method of constructing the same using the tile wedge.

1A shows a construction cross-sectional view of a conventional belt strip.

That is, for example, in the construction of the building, the tile of the ground 2 is proceeded. First, the H file 10 is constructed along the boundary line of the building.

The H file 10 is also referred to as a thumb pile, but it can be seen that a plurality of H files 10 are installed at regular intervals as shown in FIG. 1B.

It can be seen that a wale 30 is installed on the front of the H file 10 so as to connect the H files 10 horizontally to each other. That is, the wale 30 is additionally installed downward in the H file 10 constructed while being excavated to a certain depth.

A strut 40 is provided between the wale 30 and the wale 30 so as to extend across the inner space so that the wale 30 generated by the ground 30 and the H- (10) is not conducted.

Typically, the earth retaining structure includes a strand (not shown), a wale 30, and a strut 40 installed between the H file 10 and the H file 10.

Such a retaining structure is the most economical to manufacture and install members made of steel such as the H file 10, the wale 30 and the strut 40.

At this time, the wale band 30 is also usually manufactured by using an H-shaped steel material. Such H-shaped steel material is very expensive. Therefore, if an H-shaped steel having a cross-sectional size that can sufficiently secure the role of the wale 30 can be used, it is possible to construct a more economical retaining structure.

In addition, since the retaining structure is constructed while excavating the ground, construction workability and workability are very important for constructing an economical retaining structure. In order to achieve such construction, it is necessary to simplify the site work and reduce the work type that can be generated on site.

One of the prior arts disclosed for this purpose is a method of installing a wrist strap 30 by introducing a prestress.

That is, according to FIG. 1B and FIG. 1C, it can be seen that a welt 50 is installed in the H file 10.

That is, first, the wale 50 is first installed in the H file 10, the double layered material 53 is installed first so as to overlap the wale 50, and between the brackets 51 separately provided on the front surface of the double layered material 53 After the tension member 52 is installed, both ends of the tension member 52 are fixed to the bracket 51 after being strained.

Thus, since the prestress caused by the tensioning and fixing of the tension member 52 is introduced into the double-layer spring material 53, the welt 50 can more effectively resist the bending moment due to the earth pressure.

As shown in FIG. 1d, a modified example of the double-layered string according to FIG. 1c has also been disclosed. Such a double-layered wedge 63 is formed by forming a stepped portion at both ends of the wedge- And the bracket 61 and the tension member 62 are installed at the middle portion of the double-layered string.

However, as the thickness of the conventional double-layered cord increases, the prestress introduced by the tensile material does not coincide with the neutral axis of the double-layered cord, and the efficiency of introduction of the prestress is low.

FIG. 1E shows the construction of the stranded wire 63 according to FIG. 1D. That is, it can be seen that the end faces of the connecting end portions A of the laminated wedge field 63 are in contact with each other using the butt plates in the form of a vertical plate.

Such a connection end connection method may be advantageous in that it is simple in construction. However, since the connection is made using only a bolt and a nut, there is a problem that connection performance may be problematic.

It is also seen that both ends of the strut 40 are positioned so as to be in contact with the connection end A and are installed using inclined struts 41. When this method is used, The excessive stress caused by the resin 40 is concentrated, which increases the possibility of structural defects.

In addition, FIG. 1F shows a strut 70 in the form of a square tube. This strut is advantageous in that it is advantageous in warping and the like and has a large self weight. However, when the hinge fixture 72 and the hinge fixture 71) is used as the citation means (70).

However, such a citation means 70 is a separate accessory material, and there is a problem that installation work is cumbersome and therefore inefficient.

Accordingly, it is an object of the present invention to provide a stranded wale for introducing a prestress by a tensile member (steel bar, PC steel, etc.), to improve the connecting performance at the connection end of the stranded zone and to prevent the prestress caused by the tension member from coinciding with the neutral axis It is possible to adjust the eccentricity and to use it in the form of a square tube. It is also easy to lift and to distribute the stress when installed in the stranded wale, so that it can prevent buckling due to the extended length. The present invention aims to solve the problem of provision of a folded wedge which can be easily adjusted in eccentricity, a false earthquake using the same, and a construction method thereof.

According to an aspect of the present invention,

First, the connection end portions of the double-layer strips capable of eccentric adjustment are not connected to each other at their end faces, but the connection end portions are connected to each other at the step connection portions, the expansion flanges are formed at the end portions of the strut, So that stress dispersion is possible.

Secondly, in providing the eccentricity controllable eccentricity, the eccentric adjustment means is provided to allow the fixation position of the eccentric member to be adjusted from the neutral axis of the eccentricity.

The eccentric adjustment means forms an elliptical hole in the fixing plate, and when the fixing position of the tension member inserted in the elliptic hole is determined, the fixing member is tensioned in the elliptical hole in which the tension member is deflected by the position adjusting plate having the tension member hole.

Third, the struts installed between the eccentrically adjustable stranded wales are formed in the shape of a square tube, and the lifting hooks can be easily installed by the two spaced lifting holes. As the length of the strut increases, The buckling length of the strut can be reduced by using the end tilting bracket.

According to the present invention, the existing wedge and strut for the existing retaining walls are made of H-shaped steel and the spacing of the struts supporting the wedge is within 2 ~ 3m, the space for the heavy equipment is small and the working efficiency of the equipment is low, It takes too much time, the construction period is long and the construction cost is increased.

However, when a quadrangular tube strut having a stiffness equal to the stiffness of a strong axis and a weak axis is applied to a wrist band for a pre-stressed earthquake using a prestress capable of adjusting the eccentric length according to the present invention, it is possible to reduce the air shortening and the construction cost to about 30% Can be expected.

According to the present invention, it is possible to expand the narrow work space of the existing construction method to a large scale, thereby enabling effective operation of the heavy construction equipment, shortening the construction time and reducing the construction cost, and realizing economical, safe and quick construction of the earthworks.
