When carrying out excavation work, a retaining wall alone cannot resist the earth pressure of the background soil, so a large number of support materials (Strut, Earth Anchor, Raker, etc.) must be used to reinforce it.

However, the above-mentioned earth anchor method involves planting an earth anchor by digging into the adjacent site more than 10m, but when the use of the adjacent site is restricted, the strut or raker method has no choice but to be applied every 2.5m of excavation height, which is greatly disadvantageous in terms of economic feasibility and construction conditions. there is a problem.

In addition, the conventional method using braces and anchor holes tightly installs braces at intervals of 2 to 3 m in the vertical direction of the excavation, which narrows the work space and causes inconvenience in the use of heavy equipment. In addition, when anchors are used, it is difficult to use heavy equipment in urban excavations. There are problems causing significant difficulties in construction due to invasion of private land, damage to existing structures, and inflow of nearby groundwater.

[Thumb stake using guide bracket and hanging bracket]

Figure 1 is a perspective view showing a thumb pile using a guide bracket and a hanging bracket according to the present invention, Figure 2 is a front view showing a thumb pile using a guide bracket and a hanging bracket according to the present invention, and Figure 3 is a view showing the thumb pile using a guide bracket and a hanging bracket according to the present invention. It is a plan view showing a thumb pile using a guide bracket and a hanging bracket according to the present invention, Figure 4 is a cross-sectional view showing a thumb pile using a guide bracket and a hanging bracket according to the present invention, and Figure 5 is a guide bracket according to the present invention. This is an exploded perspective view showing a thumb pile using a and hanging bracket.

As shown in these drawings, the thumb pile (P) using a guide bracket and a hanging bracket according to the present invention includes a pile (100) having a predetermined shape; A guide bracket 200 coupled to the middle portion of one side of the pile 100; A hanging bracket 300 coupled to one lower end of the pile 100; It is composed of a tension member 400, one end of which is fixed to the hanging bracket 300, and the other end of which is tensioned by passing through the guide bracket 200.

That is, the thumb pile (P) using a guide bracket and a hanging bracket according to the present invention is a structure formed by organically combining a pile (100), a guide bracket (200), a hanging bracket (300), and a tension member (400). .

Here, the pile 100 is composed of any one of section steel, H-beam steel, I-beam, U-beam, A-beam, steel pipe, hollow pipe, round steel pipe, square pipe, and section steel.

In particular, the section steel is a general term for long steel pre-formed into a certain cross-sectional shape such as H-type or L-type. It is mainly used in civil engineering, architectural columns or beams, foundation piles and mechanical products, etc. There are various section steels depending on the shape of the cross section. , it is used according to epidemiological rationality and purpose of use.

In addition, the H-beam steel is a section steel with an H-shaped cross section that is widely used in the framing of large structures such as buildings and ships or in civil engineering work, and is made by hot rolling.

Here, the part corresponding to the horizontal bar in the center of the H-beam is called the web, and the parts corresponding to the vertical bars on both sides are called the upper and lower flanges. The upper and lower flanges of 300 mm or less are called junior size, and those of 300 mm or more are called senior size. .

In addition, there is an I-beam with a cross section similar to the H-beam. In the H-beam, the thickness of the upper and lower flanges is constant all the way to the end, the ends of the upper and lower flanges are not rounded, and in the I-beam, the width is smaller than the height. The difference in H-beam steel is that the width is the same as the height.

The wider one is called wide flange H-beam steel, and its overall cross-section is square, making it easy to use as a building pillar.

The specifications are specified in KS D 3503, and the shape and dimensions are specified in KS D 3051.

Meanwhile, a steel pipe is a construction material made of an alloy of iron and carbon, meaning that the cross section is a circular pipe or a hollow rectangular pipe. It should be noted that square pipes and pipes of various shapes can be used as needed.

In particular, it should be noted that no special technical requirements are required when using a circular pipe as a variety of pipes such as square pipes and closed bend pipes.

In addition, as shown in FIGS. 6 to 9, the guide bracket 200 includes upper and lower horizontal plates 210 and 220 arranged up and down at a certain distance, and the upper horizontal plate 210 and the lower water. A vertical plate 230 disposed between the flat plates 220; a semicircular fixing pulley 240 fixed to the vertical plate 230; It consists of a stopping plate 250 that is fixedly installed at a certain distance from the vertical plate 230.

It is caught on the fixing pulley 240 and the angle is changed by the semicircular fixing pulley 250 to extend horizontally toward the middle part of the pile 100.

And, as shown in FIGS. 10 to 13, the hanging bracket 300 includes a vertical plate 310 formed in a rectangular shape with a certain thickness and width; a horizontal plate 320 formed by bending at a right angle from an end of the vertical plate 310; A hanging plate 330 formed by bending at a right angle from an end of the horizontal plate 320; an inclined plate 340 disposed inclined between the vertical plate 310 and the horizontal plate 320 and having a triangular shape; The horizontal plate 320 is composed of a plurality of fixing holes 350 formed to have a certain diameter.

Here, the reason why the shapes of the vertical plate 310, the horizontal plate 320, and the inclined plate 340 are different is because of the tension of the tension member 400 installed in the fixing hole 350 of the hanging bracket 200. This is to prevent deformation and reduce the amount of steel.

That is, the hanging bracket 300 is a member in which a vertical plate 310, a horizontal plate 320, an inclined plate 340, and a fixing hole 350 are organically combined.

Here, the horizontal plate 320 is formed to be thicker than the vertical plate 310 and the inclined plate 340.

The reason why the horizontal plate 320 is formed thicker in this way is to form different thicknesses to efficiently tension the tension member 400 installed in the fixing hole 350 of the hanging bracket 300, and the vertical plate 310 ) and the inclined plate 340 are formed to have the same thickness.

Meanwhile, when the inclined plate 340 is attached to the vertical plate 310, a plurality of large inclined plates 340 are installed on the inside of the vertical plate 310, and a small inclined plate 340 is installed on the outside of the large inclined plate 340. It is installed.

The reason for changing the size of the swash plate 340 in this way is to increase the size of the swash plate 340 in the area that receives a lot of force when the tension member 400 is tensioned, and to reduce the size of the swash plate 340 in the area that receives less force. This is to prevent unnecessary waste of steel.

Meanwhile, the hanging bracket 300 is installed at the end of the thumb peg 100 while being maintained at a certain distance vertically downward from the guide bracket 200.

Here, it is structurally advantageous to install the hanging bracket 200b vertically at the lowermost end of the thumb peg 100, which is opposite to the guide bracket 300.

In addition, it should be noted that if the overall length between the guide bracket 200 and the hanging bracket 300 becomes too long, an intermediate spacer may be installed at a predetermined position of the thumb peg 100.

Meanwhile, it should be noted that the tension member 400 may be composed of a high-strength structural steel bar or steel wire.

In addition, the tension member 400 is fixed to the guide bracket 200 installed in the middle of the pile 100 and the hanging bracket 200 installed in the lower end of the pile 100.

The thumb pile (P) using the guide bracket and hanging bracket according to the present invention configured as described above is installed with the guide bracket (200) in the middle of the rear side of the pile (100), and the lower end of the pile (100). A hanging bracket 300 is installed, a tension member 400 is installed and fixed from the hanging bracket 300 toward the guide bracket 200, and the tension member 400 is tensioned with a predetermined force, Even without installing a separate support material on the excavation side, there is no risk of the pile 100 falling or collapsing into the excavation space, and excavation work can be done safely and easily at low cost even in a narrow space in the city center.
