For example, the angle formed by the main base 210 and the first extension part 211 may be an acute angle. The main base 210 may have a through hole 210a having a thread formed therein as necessary. In this case, the bolt 260 may be inserted into the through hole 210a of the main base 210 to fix the earth plate support clamp 200 to the H file as described later.

As shown in FIG. 2, surface contact with the H pile can be performed.

The support plate 200 for the earth plate may be formed by bending a metal plate such as a galvanized metal plate or iron. That is, the main base 210, the first extension part 211, and the first additional extension part 213 may be integrated.

Of course, the earth plate support clamp 200 according to this embodiment is not limited to being formed by bending the metal plate. For example, the earth plate support clamp 200 according to the present embodiment may be formed by a method such as injection molding using a polymer resin including plastic, and the like, and various modifications may be made in materials and manufacturing methods. For example, a fiber-reinforced plastic (FRP) having excellent material rigidity can be used.

Also in the shape, the space between the first extension part 211 and the first additional extension part 213 may be filled. In this case, there is a gap between the portion filling the space between the first extension portion 211 and the first additional extension portion 213 and the surface of the first additional extension portion 213 in the direction (+ y direction) of the main base 210. Space can be formed. The empty space may have the same or similar shape as the main base 210, and the width (y-axis direction) of the empty space may be the predetermined distance d shown in FIG. 2.

3 is a plan view schematically showing an H-pile-supporting clamp assembly constructed by using the support clamp 100 for the earth plate of FIG. 1 and the support clamp 200 for the earth plate of FIG. 2. The H pile-supporting clamp assembly includes an H pile 300, support clamps 100 and support clamps 200.

The H pile 300 extends from the center of the first flange 310 to the center of the second flange 320 and the first flange 310 and the second flange 320 parallel to each other. And a web 330 that connects the second flange 320 to each other. The H pile 300 may be formed of a metal plate such as galvanized metal plate or iron.

The earth plate supporting clamps 100 as described above with reference to FIG. 1 are fastened to the first flange 310. To this end, the bolt 160 may be inserted into the through hole formed in the main base 110 and having a thread formed therein. The earth plate supporting clamps 200 as described above with reference to FIG. 2 are fastened to the second flange 320. To this end, the bolt 260 may be inserted into a through hole formed in the main base 210 and having a thread formed therein.

The plate-shaped main base 110 of each of the earth plate support clamps 100 is disposed in surface contact with a surface in a direction opposite to the direction of the second flange 320 of the first flange 310 (-y direction). Accordingly, the first extension 111 connected to one end of the first flange 310 of the main base 110 in the (-y direction) extends in the direction of the second flange 320 (+ y direction). The first additional extension 113 connected to the other end of the first extension part 111 (+ y direction) forms an acute angle with the first extension part 111 and extends in the direction of the first flange 310. Accordingly, the other end of the first additional extension 113 contacts the surface of the first flange 310 in the direction of the second flange 320 (+ y direction).

The plate-shaped main base 210 of each of the earth plate support clamps 200 is disposed in surface contact with a surface in a direction opposite to the direction of the first flange 310 of the second flange 320 (+ y direction). Accordingly, the first extension part 211 connected to one end of the second flange 320 of the main base 210 in the (+ y direction) forms an acute angle with the main base 210 in the direction of the first flange 310. Extends. In addition, the first additional extension part 213 connected to the other end of the first extension part 211 in the direction of the first flange 310 of the first extension part 211 may move in the direction of the second flange 320 (+ y direction). Is extended. Accordingly, the other end of the first additional extension part 213 (+ y direction) contacts the surface of the second flange 320 in the direction of the first flange 310 (-y direction).

In the case of the H pile-supporting clamp assembly, the earth plate 410 and 420 may be interposed between the earth plate support clamp 100 and the earth plate support clamp 200. That is, the first additional extension 113 of the earth plate support clamp 100 fastened to the first flange 310 of the H pile 300 and the earth plate support clamp 200 fastened to the second flange 320. The first extension part 211 of) may be substantially parallel, and thus, between the first additional extension part 113 of the earth clamp plate support clamp 100 and the first extension part 211 of the earth clamp plate support clamp 200. The earth plate 410, 420 may be interposed. In particular, as shown in FIG. 3, the earth plate 410 positioned in the + x direction about the web 330 of the H pile 300 is located in the extended direction and the -x direction. This extended direction can be made perpendicular to each other.

In order to construct the foundation, basement or concrete body of the building, the construction site will work to excavate the ground. And in order to prevent the excavation back to collapse by earth pressure, the earthquake tent is installed on the excavation back. An H pile-supporting clamp assembly such as that shown in FIG. 3 may, together with the earth plates 410, 420, constitute such a clogging provision.

In the case of a conventional earthenware temporary installation, it is common to couple the earth plate to the H pile. That is, the earth plate is inserted between the H piles spaced apart from each other. However, in the case of such a conventional earthenware temporary installation, there was a problem that the earthenware temporary installation at the corner of the site of the excavation target is not easy, or the cost is excessively expensive and not economical. For example, the corner portion of the gulting target region may have a shape substantially perpendicular when viewed in a direction perpendicular to the target region. In this case, for example, a gap between the earth plate and the earth plate may exist at a portion where the earth plate extending in the x-axis direction and the earth plate extending in the y-axis direction may exist, thereby preventing the soil block from being properly formed. Alternatively, even if the first H file and the second H file are positioned such that the web of the first H file and the web of the second H file are perpendicular to each other at the corners, a gap exists between the first H file and the second H file, so that the soil block is properly formed. You may not lose.

However, in the case of the H pile-supporting clamp assembly as shown in FIG. 3, the earth plate fastened to the H pile 300 even if the corner portion of the gulting target region has a substantially vertical shape when viewed in a direction perpendicular to the target region. Due to the presence of the support clamps 100, 200, the earth plate 410 and the earth plate 420 may be connected to the H-pile support clamp assembly while being approximately vertical. Therefore, it is possible to implement an earthquake temporary facility that can effectively prevent the outflow of soil.

For reference, as shown in FIG. 3, the other end of the earth plate 420 having one end inserted into the H pile-supporting clamp assembly is the first flange 310 'and the second flange (H) of the conventional H pile 300'. 320 ') is inserted between the blocks, forming a temporary tent. In FIG. 3, the earth plate 420 is shown to be adjacent to the surface of the second flange 320 ′ of the H pile 300 ′ in the direction of the first flange 310 ′. This is because the situation is located in the vicinity of the surface in the direction opposite to the direction of the second flange 320 'of the first flange 310' of 300 '. Then, after the installation of the temporary blocking facility, the space between the earth plate 420 and the first flange 310 'of the H-pile 300', that is, the space between the earth plate 420 and the excavation back surface, may be soil or soil cement. backfilled with cement), such that the earth plate 420 is in close contact with the second flange 320 'of the H pile 300'.

Thus, in the case of the H pile-supporting clamp assembly as shown in FIG. 3, the earth plate 410 and the earth plate 420, even if the corner portion of the gulting target region has a substantially vertical shape when viewed in a direction perpendicular to the target region. It can be connected to the H pile-supporting clamp assembly while making it approximately vertical. Therefore, it is possible to implement an earthquake temporary facility that can effectively prevent the outflow of soil. In addition, the H pile-supporting clamp assembly is a combination of the H pile 300 and the earth plate support clamps 100 and 200, and thereafter, by removing the bolts 160 and 260 and simply dismantling them, the H pile 300 is removed. Can be reused. Of course, the support clamps 100 and 200 for the earth plate separated from the H-file 300 are also reusable.

The lengths (in the z-axis) of the support clamps 100 and 200 for the earth plate shown in FIGS. 1 and 2 may be much shorter than the lengths (in the z-axis direction) of the H pile 300. However, unlike this, as shown in FIGS. 4 and 5, the lengths (in the z-axis direction) of the support clamps 100 and 200 for the earth plate may correspond to the lengths (in the z-axis direction) of the H pile 300. It may be long. In this case, the support clamps 100 and 200 for the earth plate may slide in the longitudinal direction (z-axis direction) of the H pile 300 and may be coupled to the H pile 300, or may have a web at the edge of the first flange 310. Sliding at the side of the H pile 300 in the 330 direction (x-axis direction, see FIGS. 3 and 4) and may be coupled to the H pile 300.

On the other hand, the H piles 300 are driven to the ground prior to the excavation of the ground, and after the soil is excavated, the H piles 300 are exposed, and the earth plate support is supported on the H pile 300 located at the corner of the excavation region. The clamps 100 and 200 are fastened, and the earth plates 410 and 420 are inserted between the H piles 300, and the earth plates 410 and 420 and the excavation back surface are made of soil or soil cement. Can be filled with earthquake tents. Alternatively, the H pile-supporting clamp assembly is first made, and then, a perforation hole is formed at the corner of the excavation target region, the H pile-supporting clamp assembly is inserted into the perforation hole, and the perforation holes are formed at the edge of the other excavation target region. After forming and inserting the H piles into the corresponding drilling holes, the drilling holes may be refilled with earth and sand. And by carrying out the excavation work to expose the H pile and the H pile-support clamp assembly, the earth plate 410, 420 is inserted between the H pile 300, and then the earth plate (410, 420) and excavation back It is possible to install the earthenware temporary facility by refilling the soil with earth and soil cement.

Meanwhile, in FIG. 3, two earth plate support clamps 100 spaced apart from each other are coupled to the first flange 310 of the H pile 300, but the present invention is not limited thereto. That is, as shown in FIG. 6, the earth clamp support clamp 100 is not limited to the main base 110, the first extension 111, and the first additional extension 113, and the second extension. A part 121 and a second additional extension part 123 may be further provided.

One end of the second extension part 121 (in the -y direction) is connected to the other end (in the + x direction) of the plate-shaped main base 110, and the plane in which the main base 110 is located (zx plane) It extends in the direction which intersects (+ y direction). For example, as shown in FIG. 6, the angle formed by the main base 110 and the second extension 121 may be 90 degrees.

One end of the second additional extension part 123 (in the + x direction and the + y direction) is connected to the other end (in the + y direction) of the second extension part 121. The second additional extension part 123 extends in the direction of the main base 110 and the first extension part 111. Specifically, the second additional extension part 123 extends in a direction (-x direction and -y direction) that intersects the plane (yz plane) where the second extension part 121 is located. For example, the angle formed by the second extension 121 and the second additional extension 123 may be an acute angle. At this time, the other end (in the -x direction and the -y direction) of the second additional extension part 123 is spaced apart from the main base 110 by a predetermined distance d. In addition, in order to enable surface contact with the H pile, the second additional extension part 123 may be bent near the other end (in the -x direction and the -y direction). Through this, the distal end surface of the other end of the second additional extension portion 123 may be substantially parallel to the surface of the second additional extension portion 123 direction (+ y direction) of the main base 110.

The earth plate support clamp 100 may be formed by bending a metal plate such as a galvanized metal plate or iron. That is, the main base 110, the first extension part 111, the first additional extension part 113, the second extension part 121, and the second additional extension part 123 may be integrated.

Of course, the earth plate support clamp 100 as shown in Figure 6 is not limited to being formed by bending the metal plate. For example, the support clamp 100 for the earth plate as shown in FIG. 6 may be formed by a method such as injection molding using a polymer resin including plastic, and the like, and various modifications may be made in materials and manufacturing methods. For example, a fiber-reinforced plastic (FRP) having excellent material rigidity can be used.

Also in the shape, the space between the first extension 111 and the first additional extension 113 and the space between the second extension 121 and the second additional extension 123 may be filled. In this case, a gap is formed between a portion filling the space between the first extension part 111 and the first additional extension part 113 and the plane of the first additional extension part 113 direction (+ y direction) of the main base 110. Space can be formed. Of course, an empty space is formed between the portion filling the space between the second extension part 121 and the second additional extension part 123 and the direction of the second additional extension part 123 of the main base 110 (+ y direction). Can be formed. Such an empty space may have a shape similar to the main base 110, and the width (y-axis direction) of the empty space may be a predetermined distance d shown in FIG. Of course, when forming by injection molding or the like may also be formed in the shape as shown in FIG. The same is true in the following embodiments and modifications thereof.
