Description

  The present invention relates to a wall structure and a repair method thereof.

  When a debris flow or the like occurs on a dam, retaining wall, or revetment, it is required to dampen it. For this reason, a wall structure may be constructed on an inclined land where occurrence of debris flow or the like is assumed. As such a wall structure, there is known a structure in which a plurality of steel frames formed by enclosing four sides with a planar body are arranged side by side, and filling materials such as stone are filled in these steel frames. It has been. In addition, these steel frames resist the impact force due to earth pressure or debris flow from the back by the weight of the steel frame itself and the filling material (self weight of the steel frame body).

  Moreover, as a steel frame used for such a wall structure, there is a conventional one having a front body and a rear body (see, for example, Patent Document 1). The front body in this steel frame is configured by arranging a plurality of rod-shaped front members side by side on a rectangular frame. Similarly, the rear surface body is configured by arranging a plurality of rod-shaped rear surface materials in parallel on a rectangular frame.

  The plurality of front materials in the front body are arranged at a predetermined interval, and the width between adjacent front materials is such that the filling material does not flow out from between the front materials. Has been. Similarly, with respect to the plurality of rear surface members in the rear surface body, the plurality of rear surface members are arranged side by side with a width that prevents the outflow of the filling material. Furthermore, the frame body of the front body and the frame body of the rear body are connected by a connecting material. A wall structure is constructed by arranging a plurality of steel frames filled with these filling materials.

  Since this type of wall structure is constructed in a place where debris flow or the like is expected, it is often exposed to a harsh natural environment and used for a long period of time. For this reason, the front material and the rear material may be deformed due to deformation of the terrain and aging, or the fixing portion with the frame body may be damaged, and the front material and the rear material may be detached from the frame body. When the front material and the rear material are detached from the frame, the outflow of the filling material filled in the steel frame is assumed. To prevent the filling material from flowing out, repair the wall structure by reattaching the front or rear material to the frame when the front or rear material is detached from the frame. It is required to do.

  However, when constructing the wall structure disclosed in Patent Document 1, for example, a steel frame manufactured in a factory or the like is brought into the construction site and installed at a specified position, and the filling material is sequentially added. While filling, install an adjacent steel frame. This work is repeated to construct a wall structure by arranging a plurality of steel frames side by side.

  For this reason, when performing the repair which attaches a front surface material or a rear surface material from the steel frame in the wall structure after construction, you have to work on the field where the wall structure was constructed. Since steel frames in wall structures are often manufactured at factories, etc., it is difficult to attach the front or rear material to the frame again after the front or rear material is removed from the frame. As a result, there was a problem that the repair work would take a lot of trouble.

  Accordingly, an object of the present invention is to provide a wall structure and a repair method thereof that can easily perform repair work when a front body or the like is detached from a frame.

  A wall structure according to the present invention for solving the above problems is a wall structure that includes a front body and a rear body, and is filled with a filling material between the front body and the rear body. An outer frame member in which at least one of the body and the rear body is arranged to face each other, a rod-shaped member that is spanned between the opposed outer frame members, and a fixing member that fixes the rod-shaped member to the outer frame member A flange is formed on a side of the outer frame member on which the rod-like member is disposed, and the fixing member has a clip nut fitted into the flange and a bolt fastened to the nut portion of the clip nut. It is configured.

  In the wall structure according to the present invention, a rod-like member is fixed to the outer frame member, and a front body or a rear body is provided. The wall structure is often exposed to a harsh natural environment after construction, and the rod-shaped member may come off from the front body and the rear body. When the rod-like member is detached from the front body or the like, it is required to repair it and newly attach the rod-like member to the outer frame member. For this reason, for example, it is conceivable that a nut is disposed inside the outer frame member, and a bolt is screwed from the outside of the outer frame member to fix the rod-shaped member to the outer frame member. However, since the inside of the outer frame member is filled with filling material, it is difficult for an operator to put a hand inside the outer frame member, and bolts are arranged inside the outer frame member. It was difficult to keep.

  In this regard, the wall structure according to the present invention includes a clip nut that is fitted into a flange formed on the outer frame member. Since the clip nut can be easily attached to the wall structure after construction, the nut can be arranged by fitting the clip portion of the clip nut into the flange. Therefore, it is not necessary for the worker to arrange with a nut, and the bolt can be arranged inside the outer frame member. Therefore, the operation of attaching the rod-shaped member to the outer frame member can be easily performed. Therefore, the trouble at the time of repair work when the rod-like member such as the front member is detached from the outer frame member can be reduced.

  Here, a mounting plate having a through hole through which a bolt passes is attached to the outer frame member side end of the rod-shaped member, and the flange and the mounting plate are connected by the bolt head and the nut portion of the clip nut. It can be set as the aspect by which the outer frame member and the rod-shaped member are being fixed by pinching and pinching.

  Thus, the thickness of the portion to be tightened with the bolt and nut when fixing the rod-shaped member by attaching the mounting plate in which the through-hole through which the bolt passes is attached to the outer frame member side end of the rod-shaped member. Can be thinned. Therefore, the rod-shaped member can be firmly fixed to the outer frame member.

  Moreover, the through-hole formed in the attachment plate can be set as the aspect which is a long hole along the extension direction of a rod-shaped member.

  As described above, since the through hole formed in the mounting plate is a long hole along the extending direction of the rod-like member, it is possible to allow a shift when the bolt is passed through the through hole, and accordingly, the outer frame member. It is possible to reduce the time and effort required for attaching the rod-shaped member to the. Furthermore, since the elongated hole is along the extending direction of the rod-shaped member, a slight movement in the longitudinal direction can be allowed after the rod-shaped member is attached. Therefore, it is possible to make it difficult for the rod-shaped member to be detached from the outer frame member.

  On the other hand, the manufacturing method of the wall structure according to the present invention that has solved the above-described problems includes a front surface and a rear surface, and the front surface of the wall structure that is filled with filling material between the front surface and the rear surface. An outer frame member in which at least one of the body and the rear body is arranged to face each other, a rod-shaped member that is spanned between the opposed outer frame members, and a fixing member that fixes the rod-shaped member to the outer frame member A method for repairing a wall structure comprising a clip nut fitted into a flange formed on a rod-like member side of an outer frame member, and tightening a bolt on a nut portion of the clip nut, whereby the outer frame member and the rod-like member are It is fixed.

  Thus, according to the present invention, it is possible to provide a wall structure and a repair method thereof that can easily perform repair work when the front body and the like are detached from the frame.

  The rear surface body 2 includes the same frame material 21 and beam material 22 as the front surface body 1. Further, a joint 23 is provided at a portion where the frame material 21 and the beam material 22 overlap each other, and ends of the frame material 21 and the beam material 22 are joined by the joint 23. Further, a rear surface member 24 is disposed between the two beam members 22 that are provided side by side. The arrangement mode of the frame material 21, the beam material 22, the joint 23, and the rear surface material 24 is the same as the arrangement mode of the frame material 11, the beam material 12, the joint 13, and the front surface material 14 of the front body 1.

  The upper surface body 3 includes a plurality of upper surface materials 31 that are respectively spanned between the upper beam members 12U and 22U that are respectively arranged on the upper side of the front surface body 1 and the rear surface body 2.

It is delivered and arranged.

  Moreover, as shown in FIG. 4, the filling material C is provided inside the steel frame W. As shown in FIG. The filling material C is composed of, for example, locally generated earth and sand, pebbles (gravels less than 15 cm), and the like. As the assembling of the dam X proceeds, the filling material C is introduced into the steel frame W and finally filled into the steel frame W. The separation distance between adjacent front members 14 or repair front members 50 in the front body 1 and the separation distance between adjacent rear members 24 in the rear body 2 are such widths that the filling material C does not flow out. .

  As shown in FIG. 2, a plurality of steel frames W formed by being surrounded by the front body 1, the rear body 2, the top body 3, and the bottom body 4 are provided as a dam X. Since the face material of the dam X needs to be able to withstand the pressure (earth pressure) of the filling material C, the face member disposed below is more separated from the front member 14 than the face member disposed above. The width is narrowed to support the load applied from above.

  Such a dam X is constructed in an environment exposed to harsh nature, such as an inclined land where the occurrence of debris flow is assumed, and is used over a long period of time. For this reason, the front member 14 may be detached from the beam member 12 because the front member 14 is deformed due to deformation of the terrain or aging, or the fixing portions with the beam members 12 and 22 are damaged. This problem can also occur between the rear face member 24 and the beam member 22 in the rear face body 2. Even when the front member 14 and the rear member 24 are detached, the filling material C is temporarily in a stable state due to the engagement of gravel, and therefore the filling material C does not flow out immediately. .

  However, if the state in which the front member 14 and the rear member 24 are detached from the beam members 12 and 22 for a long period of time as described above, the filling member C is affected by rainwater and the stable state is lost. There is concern that it will gradually flow out of W and affect the stability due to the weight of the steel frame. In order to eliminate such a concern, when the front member 14 is detached from the flanges 12A to 12D such as the beam member 12, the repair front member 50 is attached to the removed member 14 to repair the steel frame W. Plan. By performing such repair, the function of the steel frame W can be maintained over a long period of time.

  Here, for example, when repairing the steel frame W, it may be possible to attach a new front material 14 or the like instead of the damaged front material 14 or the like in the construction of the steel frame W. However, since the repair of the steel frame W is performed at the site where the steel frame W is constructed, in order to attach the front material 14 to the beam material 12 in the same manner as when the steel frame W is constructed, the beam material is used. For example, it is necessary to perform welding at the site where the steel frame W is constructed, such as welding bolts 12 and 22, and much preparation is required for the welding.

  It is also conceivable to fix the front member 14 to the beam members 12 and 12 using bolts and nuts. However, in that case, it is necessary to perform the mounting operation while supporting the nut from the outside of the steel frame W. For this reason, an operator's hand etc. must be inserted in the back side of flange 12A-12D, and a nut must be supported, and the effort becomes very large.

  In this respect, in the present embodiment, the repair front material 50 is used instead of the front material 14 in repairing the steel frame W. In the repair front material 50, the nut portion 62 of the clip nut 60 is used as a nut into which the bolt 54 is screwed. For this reason, when the bolt 54 is screwed into the nut portion 62, it is not necessary for the operator to support the nut portion 62, so that the repair front member 50 can be easily attached, and the labor required for the repair work of the steel frame W can be reduced. Can be reduced.

  Then, the repair method of the steel frame W which concerns on this embodiment is demonstrated with reference to FIG. FIG. 5 is an explanatory diagram for explaining the repair procedure of the steel frame, and FIG. 6 is an explanatory diagram for explaining the procedure following FIG. When the steel frame W is installed for a long period of time, as shown in FIG. 5A, the front member 14 attached to the beam member 12 in the front body 1 is damaged or the front member 14 is detached. Sometimes. Similarly, the rear surface member 24 in the rear surface body 2 may be damaged or detached from the beam material 22. These restorations will be described by taking the restoration of the front member 14 as an example.

  When the repair of the steel frame W is started, the repair front material 50 shown in FIG. 3 is attached to the repair site in the beam material 12. Therefore, as shown in FIG. 5A, when a part of the front material 14 damaged by the beam material 12 remains fixed to the beam material 12, the front surface damaged from the beam material 12 is obtained. Remove the material 14. Then, as shown in FIG. 5B, the front member 14 is not attached to the flanges 12C and 12D of the beam members 12M and 12L. Further, when the front member 14 is present around the beam member 12, the front member 14 is removed. Further, when the bolt that has fixed the front member 14 remains on the flanges 12C and 12D, the bolt is also removed.

  Next, the repair front material 50 shown in FIG. 3 is attached to the place where the front material 14 was attached. Therefore, first, as shown in FIGS. 6A and 7A, the clip nut 60 is attached to the flange 12C of the beam material 12M. At this time, the clip nut 60 is positioned at a position where the through hole 63 formed in the clip nut 60 is aligned with the through holes 12C1 and 12D1 formed in the flanges 12C and 12D. Moreover, the nut part 62 in the clip nut 60 is arrange | positioned inside flange 12C, 12D. At this time, the clip nut 60 can be attached to the beam members 12M and 12L simply by fitting the clip portion 61 of the clip nut 60 into the flanges 12C and 12D of the beam members 12M and 12L.

  When the clip nut 60 is thus attached, the attachment plates 52 and 52 of the repair front material 50 are aligned with the clip portion 61 of the clip nut 60, as shown in FIGS. 6B and 7B. At this time, the mounting plate 52 is arranged so that the bolt through holes 53 formed in the mounting plates 52 and 52 and the through holes 63 formed in the clip portion 61 of the clip nut 60 are substantially concentric.

  After the mounting plates 52 and 52 are arranged, the thread portion of the bolt 54 is inserted from the outside of the flange 12C of the intermediate beam member 12M toward the bolt through hole 53. Since the screw portion of the bolt inserted from the bolt through hole 53 contacts the nut portion 62 of the clip nut 60, the bolt 54 is rotated as it is and the bolt 54 is screwed into the nut portion 62.

  At this time, since the nut portion 62 is fixed to the clip portion 61, it is suppressed that the nut portion 62 is rotated together with the bolt 54 when the bolt 54 is rotated. For this reason, even if an operator or the like does not support the nut portion 62 from the outside of the steel frame W, the bolt 54 can be screwed into the nut portion 62. Thus, by screwing the bolt 54 into the nut portion 62, the mounting plate 52 of the repair front material 50, the clip portion 61 of the clip nut 60, and the flange 12A are sandwiched between the head portion of the bolt 54 and the nut portion 62. The upper part of the repair front material 50 is fixed to the middle beam material 12M.

  After the upper part of the repair front member 50 is fixed to the middle beam member 12M, the lower part of the repair front member 50 is fixed to the lower beam member 12L. The procedure for fixing the lower portion of the repair front material 50 to the lower beam material 12L is substantially the same as the procedure for fixing the upper portion of the repair front material 50 to the middle beam material 12M. Thus, the repair work by attaching the repair front material 50 is completed.

  Thus, in the repair method of the steel frame W according to the present embodiment, when repairing the steel frame W in which the front material 14 is damaged, the repair front material 50 is used instead of the damaged front material 14. Yes. Further, even when the rear face member 24 is damaged, the steel frame W is repaired using the repaired rear face member similar to the repair front member 50. When performing repair using the repair front material 50, clip nuts 60 are attached in advance to the beam materials 12M and 12L. When the repair front member 50 is attached to the beam members 12M and 12L using the bolt 54 by using the clip nut 60 attached in advance, a nut positioned on the back side of the flange 12C of the beam members 12M and 12L is used as an operator. No longer need to support. Therefore, the attachment work of the repair front material 50 can be performed only from the outside of the steel frame W, and the labor of construction can be reduced.

  Moreover, the nut part 62 in the clip nut 60 is arrange | positioned at the back side of the flange 12C in beam material 12M, 12L. Further, since the repair front material 50 is provided with the mounting plate 52, the head portion of the bolt 54 and the nut portion 62 sandwich the clip portion 61 of the clip nut 60, the flanges 12C of the beam members 12M and 12L, and the mounting plate 52. The repair front material 50 is fixed to the beam material 12. Therefore, since the thickness of the part fastened by the bolt 54 and the nut part 62 can be reduced, the repair front material 50 can be firmly fixed to the beam material 12.

  Further, the bolt through hole 53 formed in the attachment plate 52 of the repair front material 50 is a long hole along the extending direction of the rod-like portion 51. For this reason, since the shift | offset | difference at the time of making the volt | bolt 54 penetrate to the volt | bolt through-hole 53 can be accept | permitted, the effort concerning attachment of the repair front material 50 with respect to the beam material 12 can be reduced. Furthermore, since the longitudinal direction of the through-hole 63 is along the extending direction of the rod-shaped portion 51, a slight movement in the longitudinal direction is allowed after the rod-shaped portion 51 is attached to the beam members 12M and 12L. Can do. Therefore, it is possible to make it difficult for the repair front material 50 to be detached from the beam material 12.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the above embodiment, the repair front material 50 is fixed via the clip nut 60 on both the upper and lower sides of the repair front material 50. On the other hand, it can also be set as the aspect which fixes the repair front material 50 via the clip nut 60 about one side of the repair front material 50. FIG. In this case, the end opposite to the side fixed through the clip nut 60 may be fixed by a fitting member in which a slit that can be fitted into the flange 12C of the beam member 12 is formed instead of the mounting plate 52, for example. it can. By using such a fitting member, it is not necessary to use a clip nut, which can contribute to a reduction in the number of parts. In addition, since work such as bolting is not necessary, it is possible to reduce the labor of mounting work.

  Moreover, in the said embodiment, it replaces with the front material 14 and the rear surface material 24, but it is made to use a repair front material (surface material after repair), but the same repair material is used also about the upper surface material 31 of the upper surface body 3, etc. Can do. Furthermore, in the said embodiment, although the through-hole 12C1 which penetrates a volt | bolt is beforehand formed in the flange 12C in the beam material 12, it uses a clip nut for the flange in the beam material in which this through-hole is not formed, and repairs front surface. It can also be set as the aspect which attaches material etc. In this case, it is possible to form a surplus portion that does not overlap the flange in the clip portion of the clip nut, and to form a through hole through which the bolt penetrates in the surplus portion. Or it can also be set as the aspect which attaches a clip nut after forming a through-hole in a flange in the field.
