Insertion and withdrawal device}

The present invention relates to a device for entering or drawing an H beam or a steel sheet in civil construction, and more specifically, using a hydraulic cylinder to minimize the vibration and noise while the H beam or the steel sheet is incorporated into the ground or ground. The present invention relates to an indentation and drawing device for drawing an H beam or a steel sheet.

In general, in the construction work, a burrow construction having a depth below the ground is carried out to build underground structures such as a basement of a building or a subway, and a protective wall is installed to prevent the soil wall from collapsing due to earth pressure during the construction. In addition, the leveling work should be carried out to prevent the groundwater from the ground flowing into the construction area.

In this way, the excavation work having a depth to the lower side of the ground by the construction method generally used for the soil barrier and the degree.

The method as described above arranges the H beam at a predetermined interval to prevent the inflow of soil or groundwater into the ground by earth pressure. After inserting the earthen plate made of wood between the H beam and the H beam to install the earthquake structure to fill the soil behind the earthquake structure formed space to stabilize the ground.

The above method has a problem in that the barrier function is prevented from inflow of groundwater due to the formation of a protective wall using a plurality of earthen boards made of wood, and the rigidity is insufficient. In addition, it is difficult to recycle the earthen board made of wood after construction, there was a problem that environmental pollution occurs by embedding in the ground.

The lifting body 130 has a moving groove 140 is formed in the longitudinal direction on the center side and is moved up and down in the height direction by the lifting cylinder 120. The moving groove 140 serves as a passage through which the H beam 10 or the steel sheet 20 moves up and down. The elevating body 130 is fixed to the left and right symmetry so that the clamp cylinder 150 toward the moving groove 140. The clamp cylinder 150 is a clamp 151 is coupled to the rod end. The clamp 151 clamps the H beam 10 or the steel sheet 20 to fix the lifting body 130.

Referring to FIG. 5, the moving groove 140 may include a H beam groove 141 through which the H beam 10 may move and a steel plate 20 extending from one surface of the H beam groove 141. It may be made of a groove 142. The H beam groove 141 is a passage through which the H beam 10 moves up and down and may be formed to have a size that allows the width and width of the H beam 10 to pass therethrough. The steel plate groove 142 may extend from one surface of the H beam groove 141 to a size through which the width of the steel sheet 20 passes through a passage through which the steel sheet 20 moves up and down.

2 and 5, the lifting body 130 may have a steel plate guide 143 formed above the end of the steel plate groove 142. The steel plate guide 143 may be formed with a "V" groove. Since it is not easy to accurately position the steel plate 20 in the narrow steel plate groove 142, the steel plate guide 143 having the “V” groove is formed on the upper side of the end of the steel plate groove 142. When the one end of the steel sheet 20 is in close contact with the "V" groove, and then clamping the steel sheet 20 with the clamp 151, the steel sheet 20 can pass through the steel sheet groove 142 Can be positioned to Steel plate guide 143 of the "V" shape as described above also serves to reinforce the end of the steel plate groove 142 so as to prevent the end of the steel plate groove 142 from being damaged by hitting the steel plate 20.

The indentation and drawing device 100 having the above structure flows so that the elevating body 130 is horizontal even when the base 110 supported on the ground on which the H beam 10 or the steel sheet 20 is inclined is inclined. It is possible to absorb the flow due to the strong lifting pressure of the elevating cylinder 120 when drawing the H beam 10 or the steel sheet 20 in the ground.

2, 3, and 4, the clamp 151 may be formed in a concave-convex shape in which the clamping portion of the H beam 10 or the steel sheet 20 is clamped. The smaller the area acting, the greater the pressure. If the portion of the clamp 151 that is in contact with the H beam 10 or the steel sheet 20 is flat, the H beam 10 or the steel sheet 20 may easily slide on the clamp 151. Therefore, it is preferable to form a portion of the clamp 151 in contact with the H beam 10 or the steel sheet 20 in an uneven shape.

In addition, the lifting cylinder 120 and the clamp cylinder 150 may be operated by different hydraulic lines, respectively. When the H beam 10 or the steel sheet 20 is inserted into the ground, the lifting cylinder 120 clamps and lowers the H beam 10 or the steel sheet 20 at the raised position. After that, the clamping 151 releases the clamping force on the H beam 10 or the steel sheet 20 and repeats the operation of rising again.
