Description

Soil retaining plate}

The present invention relates to an earth plate, and more particularly, to a earth plate that can be folded and easily installed and removed between H-beam type thumb piles.

Soil boards are used for earth retaining works that are temporarily implemented to prevent the collapse of the surrounding earth and sand at construction and civil engineering sites.

Referring to FIG. 1, a method of carrying out earth retaining work using such an earth plate is described, a plurality of H-beam type thumb piles driven into the ground at regular intervals and inserted from above between the thumb piles It consists of earth plates that are supported while being inserted into the flange formed on the side of the thumb pile, and are stacked in the vertical direction.

However, both sides of the earth plate are inserted into the flange of the thumb pile and installed while being sequentially stacked from the top, and the stacked earth plates are removed by separating them upward one by one, but in this case, both sides of the earth plate are inside the flange of the thumb pile If it is stuck in, it is very difficult to install or remove, and there is a problem in that a lot of time and manpower are required to solve it.

That is, when the earth plate is installed, when the earth plate is supported by the flange and is caught in the web, which is the inner end of the flange, while the earth plate is descending, the work is stopped while the worker removes the jammed state, and similarly to remove the earth plate Even in this case, there was a problem in that the work time was increased by jamming.

Therefore, in order to solve this problem, in Patent Registration No. 10-1844245 (length-adjustable earth plate that is easy to install), slot holes of a certain length are formed in the center at a certain distance from both ends on one side of the height side of the outer body of the earth plate. In addition, on one side of the height side of the inner body of the earth plate, a plurality of perforations of a certain diameter are formed at regular intervals in the center at a certain distance from both ends, and the movement of the inner body of the earth plate is performed by inserting a moving jig into the perforations visible through the slot hole to exert external force. It is configured to have a structure in which the length of the entire earth plate is varied by applying and moving left and right while sliding inside the earth plate outer body.

However, according to Patent Registration No. 10-1844245 (length-adjustable earth plate that is easy to install), the workability is very poor because the length of each earth plate to be stacked and installed between thumb piles must be individually adjusted. .

in other words. At earth retaining construction sites, hundreds to thousands of earth plates are used depending on the size, but it takes a lot of time for workers to adjust the length of earth plates one by one, which increases work time as well as length adjustment by manpower. this will not be good.

The lower part of the first protrusion 140 is inserted into and fixed to the groove between the first front plate 110 and the first rear plate 130, and the upper part of the first front plate 110 and the first rear plate ( 130), and has a shape that protrudes upward more than the upper end portion, and the first protrusion of another soil plate stacked on the lower side is inserted into the lower insertion groove 101 on the lower side.

A tow hook 141 may be formed at a position corresponding to the portion where the hinge holes 111 and 131 are formed in the first protrusion 140, and as already mentioned above, the tow hook 141 is the first plate ( 100) and the second plate 200 is preferably formed at a position corresponding to the center of gravity, and the first protrusion 140 as well as the first front plate 110, the first rear plate 130, and the second front plate 210, the second rear plate 230, the second protrusion 240, etc. may be formed at any position corresponding to the center of gravity.

The second plate 200 is formed to have a shape facing left and right with the first plate 100, and the second front plate 210 has a shape with rounded corners, and the first front plate ( 110) has a rounded shape at one end in the direction of looking, and the second rear plate 230 also has a rounded shape at each corner and one end facing the first rear plate 130 has a rounded shape. It has a true shape, so that the rounded portion of the first plate 100 and the rounded portion of the second plate 200 come into contact with each other.

At this time, the rounded portion is rounded in the direction in which the first plate 100 and the second plate 200 rotate downward.

In addition, like the first connection part 120, the second connection part 220 is located between the second front plate 210 and the second rear plate 230 and is fixed by welding or the like, and is connected to the second front plate 210. Since the upper and lower parts of the second rear plate 230 are spaced apart from the outer part and fixed to the inside, grooves are naturally formed in the upper and lower parts between the second front plate 210 and the second rear plate 230. In the groove formed on the upper side, a second protrusion 240 made of a rectangular pipe is naturally inserted in the longitudinal direction and fixed by welding or the like.

Therefore, the lower part of the second protrusion 240 is inserted into and fixed to the groove between the second front plate 210 and the second rear plate 230, and the upper part is inserted between the second front plate 210 and the second rear surface. It has a shape that protrudes more upward than the upper end of the plate 230, and the second protrusion of another earth plate stacked on the lower side is inserted into the lower insertion groove 201 at the lower side.

Also, like the first plate 100, through-holes 213 and 233 are formed in the second front plate 210 and the second back plate 230 of the second plate 200, and the through-holes 213 and 233 are also reinforced. And it may have a structure in which the drainage part 250 connects and reinforces the second plate 200 and at the same time enables drainage.

The second front plate 210 and the second rear plate 230 have a first extension plate 211 and a second extension plate for hinge coupling between the first front plate 110 and the first rear plate 130 231 is further provided, which is difficult to hinge when one end of the first plate 100 and one end of the second plate 200 come into contact with each other, so that the first extension plate 211 and the second extension This is to match the hinge holes 111 formed on the first front plate 110 and the hinge holes 131 formed on the first rear plate 130 by forming hinge holes 212 and 232 on the plate 231, respectively.

Therefore, one side portion of the first extension plate 211 is fixed to the outer portion of the front surface of the second front plate 210 by welding or the like, so that it extends to the front portion of the first front plate 110, and hinges at the extended portion. A hinge hole 212 is formed at a position corresponding to the ball 111.

In addition, one side portion of the second extension plate 231 is also fixed to the outer portion of the rear surface of the second rear plate 230 by welding or the like, so that it extends to the rear portion of the first rear plate 130, and hinges at the extended portion A hinge hole 232 is formed at a position corresponding to the ball 131.

Therefore, the rounded one-side end of the second front plate 210 is brought into contact with each other on the rounded one-side end of the first front plate 110, and the second rear surface is also placed on the rounded one-side end of the first rear plate 130. When the rounded one-side ends of the plate 230 come into contact with each other, the hinge holes 111, 212, 131, and 232 are naturally matched, and the pin-shaped hinge portion 300 is inserted into the matched hinge holes 111, 212, 131, and 232 to provide a nut 310 When fastened by ), the first plate 100 and the second plate 200 are rotatably coupled around the hinge part 300 .

5 is a road for explaining the state of installing and removing the earth plate between the H-beams when earth retaining work is performed by the earth plate of the present invention, and the link 510 at the bottom of the wire 500 connected to the crane is installed, and when the connecting ring 510 is fastened to the tow ring 141 and then the earth plate is towed upward, the first plate 100 and the second plate 200 centered on the hinge part 300 are lowered rotates and folds.

At this time, the rounded portions formed at the ends of one side of the first plate 100 and the second plate 200 rotate downward while contacting each other, but the hinge portion 300 is eccentric from the rounded portions in contact with each other Because of this, the first plate 100 and the second plate 200 are folded while maintaining a constant angle without being completely folded.

While maintaining the angle, the folded earth plate is lowered between the H-beams 400 and 410 until it comes into contact with the upper side of the earth plate stacked on the lower side. At this time, the first plate 100 and the second plate 200 By widening the folded angle, the outer portion of the H-beams 400 and 410 can be lowered while being inserted into the flanges 401 and 411 or lowered without being inserted into the flanges 401 and 411.

At this time, since the outer portions of the first plate 100 and the second plate 200 do not come into contact with the webs 402 and 412, they do not get caught and smoothly descend.

While lowering the soil plate, when the outer rounded corners of the lower insertion grooves 101 and 201 formed on the lower side coincide with the first protrusion and the second protrusion of the lower earth plate, and then continue to descend, While the first plate 100 and the second plate 200 are unfolded with the first protrusion and the second protrusion inserted, both sides thereof are inserted into the flanges 401 and 411, respectively, and the first plate 100 and the second plate ( 200) is completely horizontally unfolded, the installation between the H-beams 400 and 410 is completed.

That is, the first protrusion and the second protrusion of the lower earth plate are inserted into the lower insertion grooves 101 and 201 to guide the first plate 100 and the second plate 200 toward the flanges 401 and 411. It serves as a guide.

At this time, since the edges of the first plate 100 and the second plate 200 have a rounded shape, the webs 402 and 412 are naturally unfolded inside the flanges 401 and 411 without damage such as scratches, and the first plate ( 100) and both ends of the second plate 200 are installed close to or in contact with the webs 402 and 412, and the first and second projections of the lower earth plate are inserted in the longitudinal direction of the lower insertion grooves 101 and 201, thereby inserting each earth plate While maintaining this vertical state, the bearing capacity against earth pressure can be greatly increased.

In addition, the lower end of the first connection portion 120 is formed only to a position where interference with the connection ring 141 does not occur, so that the connection ring of the lower soil plate is formed between the first front plate 110 and the second front plate 130. It is located at the gap, so that the first plate 100 and the second plate 200 can be stacked on the upper side of the lower earth plate in a completely horizontally unfolded state.

In the case of removing the soil plate, when the wire 500 is connected to the link 141 and then pulled upward, the first plate 100 and the second plate 200 are moved downward by the hinge part 300 As it is folded, it is pulled upward along the flanges 401 and 410, and at this time, both ends of the first plate 100 and the second plate 200 are separated from the webs 402 and 412, so they are pulled away without being caught.

Of course, if the folded length of the first plate 100 and the second plate 200 is shorter than the distance between the H-beams 400 and 410, the H-beams 400 and 410 are immediately separated from each other forward or backward to pull upwards. It can be removed by doing so, and the workability is greatly improved.

6 is another embodiment of the present invention, in which the front plates 110 and 210 and the rear plates 130 and 230 of the first plate 100 and the second plate 200 are made of one metal plate, respectively, and these front plates 110 and 210 ) Bends the back plates 130 and 230 long in the longitudinal direction, that is, in the transverse direction, or bends them in the longitudinal direction to form the ribs 114 and 214 and 134 and 234, and then the rear parts of the front plates 110 and 210 and the front parts of the rear plates 130 and 230 are brought into contact with each other and joined to each other by welding or bolts.

At this time, the lower portions of the front plates 110 and 210 are bent forward and the lower portions of the rear plates 130 and 230 are bent backward to naturally form the lower insertion grooves 101 and 201 so that the protrusions of the earth plates located at the lower side can be inserted. let it be
