Description

[0001] The deepened sheet plate having a structure for preventing steel plate deviation [

The present invention relates to a construction for inserting a steel plate between H-shaped files for prevention of slope failure and construction work in the construction of underground structures of various buildings. More particularly, The present invention relates to a structure for preventing slippage of a steel plate, which is simple in construction work and secures excellent water repellency of a structure, because it is supported by an engaging means and prevented from being released to the outside.

In general, to construct underground structures of various buildings, terraces are constructed to excavate the ground, and in order to prevent the collapse of the gravels, the installation of the retaining structures and the work of cutting off the inflow of groundwater leached from the ground .

Many methods have been known in the past for the installation of the retaining structure and the ordering work. Among them, an H-shaped file is inserted into the ground and a wood or iron steel plate is inserted between the H-shaped files to construct a retaining structure, The method of stabilizing the surrounding ground by filling the soil behind the retaining structure was mainly used.

However, the structure in which the wood is inserted between the H-shaped files has a problem that the rigidity and order functions are inferior and the wood is difficult to reuse after construction. Recently, a structure using a steel plate is mainly used.

Particularly, in the temporary retaining structure of Patent Application No. 10-10-882831, a steel plate is inserted into both sides of the H-shaped pile to be inserted in the ground, and a bending portion bent at both ends of the steel plate is inserted It can be used to reinforce the stiffness of the steel plate and to provide underground excavation work after installing the temporary earth retaining structure so as to stabilize the ground and effectively prevent the ground collapse and the inflow of soil or groundwater.

However, when the H-shaped file is inserted into the ground, the vertical strain of the H-shaped file is increased as the depth of the H-shaped file is increased. Therefore, both ends of the steel sheet spread out from the recess of the H- There is a problem that a gap is generated between the file and the steel sheet.

That is, there is a problem that water leakage occurs in the retaining structure due to a clearance gap between the H-shaped file and the steel plate, resulting in drastically deteriorating water repellency.

In addition, the above-mentioned temporary retention structure uses a complicated and heavy guide beam structure when inserting the H-shaped file, and the guide beam structure must be moved when the steel plate is inserted after inserting the H-shaped file, .

Of course, the Japanese Patent Registration No. 10-1232604 discloses a method of manufacturing a steel plate by forming an upper and lower assembly groove in a web position of an H-shaped pile to restrain the horizontal displacement of the steel plate due to earth pressure by inserting and assembling the bent portions at both ends of the steel plate, The present invention has been made to solve the above-described problems. However, the manufacturing work for forming the assembly groove for inserting the bent portions at both ends of the steel plate into the web of the H-shaped pile is inconvenient Even if a slight error occurs in the insertion position of the H-shaped file, it can not be assembled with each other, and even if the insertion position of the H-shaped file is correct, If there is an error, the steel plate can not be inserted all the way to the end. Life was often.

As shown in FIGS. 1 to 7, a temporary soil retaining structure having a steel plate departure-avoiding structure according to the present invention includes an H-shaped file 100 inserted into the ground and a plurality of bent portions 210 are inserted into recessed portions 110 on both sides of the H-shaped file 100.

The bent portion 210 of the steel plate 200 is engaged with the outer portion of the concave portion 110 of the H-shaped file 100 while forming the interval T at which the bent portion 210 of the steel plate 200 can flow inward and outward. And an engaging means 300 for supporting the disengagement prevention member.

The engaging means 300 is formed by protruding a locking projection 310 from the both side recessed portions 110 of the H-shaped file 100 to the inside of the one side flange 115.

At this time, the position of the locking protrusion 310 is formed at a position slightly inward of the flange end or the end of the recessed portion 110.

The locking protrusion 310 is fixed to the H-shaped file 100 by welding or bolting.

5, the latching protrusions 310 may be formed to extend in one direction along the longitudinal direction of the H-shaped file 100, or may be formed to be divided into a plurality of portions in a position spaced apart by a predetermined distance as shown in FIG. 6 .

7, when the locking protrusions 310 are formed at a plurality of positions spaced apart from each other by a predetermined distance, the locking protrusions 310 may be formed to have inclined faces 311 inclined toward the inside of the recesses 110 from the upper portion to the lower portion .

Although not shown in the drawings, the latching protrusions 310 may be configured to integrally bend the ends of the side flanges 115 in the both side recessed portions 110 of the H-shaped file 100, to be.

The bending portion 210 of the steel plate 200 is bent at a length of the recessed portion 110 of the H-shaped pile 100 so that the width of the bent portion 210 does not substantially flow in the width direction, The steel plate 200 and the H-shaped file 100 are more closely adhered to each other to ensure airtightness.

Hereinafter, the operation and operation of the present invention will be described.

First, the construction process will be described. The H-shaped piles 100 are inserted into the ground at a predetermined interval and the steel sheets 200 are inserted between the H-shaped piles 100.

That is, the bent portions 210 at both ends of the steel plate 200 are inserted into the recessed portions 110 of the H-shaped file 100.

At this time, the engaging means 300 is provided inside the one side flange 115 at both side recessed portions 110 of the H-shaped file 100 so that the bent portion 210 of the steel plate 200 is hooked So that it is possible to prevent the formation of a spacing distance between the H-shaped pile 100 and the steel plate 200 as in the prior art, thereby preventing leakage of the retaining structure and securing excellent water repellency.

In particular, the engaging means 300 of the H-shaped file 100 is provided in the concave portion 110 slightly inward of the end or end of the one side flange, so that the interval between the engaging portions 210 of the steel plate 200 So that the work of inserting and installing the steel plate 200 between the H-shaped files 100 is easily provided.

That is, when the H-type file 100 is inserted into the ground, vertical errors are generated as the depth of excavation deepens, so that even when the upper and lower portions of the H-type file 100 are eccentrically installed, The bent portion 210 of the steel sheet 200 can flow to the inside and outside of the gap T at which the steel sheet 200 can flow.

Even when the perpendicularity error of the H-shaped file 100 is slightly out of the interval T at which the bent portion 210 of the steel sheet 200 can flow inward and outward, The bent portion 210 of the steel sheet is caught by the engaging means 300 at the concave portion 110 of the H-shaped file 100 to pull the H-shaped file 100 by the applied external force, So that the gap between the H-shaped pile 100 and the steel plate 200 is prevented from being formed.

The hooking means 300 of the H-shaped file 100 may be formed by welding or bolt-fastening the hooking protrusion 310 to the inside of the one side flange 115 from the both side recessed portions 110 of the H- The hooking protrusions 310 extend in one direction along the longitudinal direction of the H-shaped pile 100 or are divided into a plurality of positions spaced apart from each other by a predetermined distance.

That is, the hooking protrusions 310 of the H-shaped file 100 support the bent portions 210 at both ends of the steel sheet 200 to be caught and prevented from being separated. When the hooking protrusions 310 are extended to one, Of course, the stiffness is further increased, and when it is divided and formed into a plurality of pieces, the manufacturing work of joining the locking protrusions is advantageous.

7, the locking protrusions 310 may be divided into a plurality of slits 311 inclined toward the inside of the recess 110 from the upper portion to the lower portion as shown in FIG. 7, Both ends of the steel plate 200 are guided to the inside of the recess along the inclined surface 311 rather than being caught by the latching protrusion 310 so that the steel plate 200 is inserted smoothly. It is possible to more effectively correct the vertical error of the H-shaped file.

The structure in which the locking protrusions 310 are additionally attached to the H-shaped file 100 as described above also has the advantage of reinforcing the stiffness of the entire H-shaped file 100 more than the conventional one.

In addition, the hooking protrusion 310 of the H-shaped file 100 may be formed by integrally bending the end of the side flange 115 in the both side recessed portions 110 of the H- It is possible to obtain the same operational effects as those described above.
