FIG. 1 and FIG. 2 show an example of an attachment structure for the belly raising material 20 on the retaining wall 10.

The mountain retaining wall 10 is a main pile horizontal sheet pile wall, a soil cement solidified continuous wall, or the like, and a plurality of belly raising brackets 30 for mounting the belly raising material 20 are attached to the leveling attachment level of the mountain retaining wall 10. ing.
The flank member 20 is an H-shaped steel made up of two flanges 20a and one web 20b, and a plurality of bolt holes 20c are opened at equal intervals along the longitudinal direction.

The abdomen 20 is disposed on the abdomen bracket 30 and extends in the horizontal direction so that the surface of the flange 20a is a vertical surface, in other words, the flange 20a is on the front side and the back side.
In the joint portion 50 that joins the end portions of the belly prosthesis 20 to each other, an attachment plate (joint plate) 40 is fixed so as to straddle the flange 20a on the front side of the two antiprosthetic members 20, and the joint unit 50 is attached. Reinforced by the contact plate 40.

  The attachment plate 40 is provided with a plurality of bolt holes 40a corresponding to the arrangement of the bolt holes 20c that are opened in the belly raising material 20, and the bolts 20c of the belly raising material 20 are provided with the bolts 20c. The position where the bolt hole 40a overlaps is set as a fixed position, and the attachment plate 40 is fixed at a position straddling both flanges 20a to be abutted by the bolts inserted through both the bolt holes 20c and 40a.

A backing material 60 is interposed in the gap between the flange 20 a on the back side (mounting wall 10 side) of the belly raising material 20 and the mountain retaining wall 10, and earth pressure passes through the backing material 60 and the belly raising material 20. It is configured to be transmitted to.
Furthermore, a cut beam, a fire beam, etc., not shown in the figure, are assembled to the belly material 20.

Next, the step of fixing the attachment plate 40 to the joint portion 50 in the step of abutting and joining the end portions of the abdominal material 20 will be described in detail.
3 and 4 show one mode of the slide jig 70 used in the process of fixing the splicing plate 40 to the joint portion 50.

The slide jig 70 is a jig for attaching the attachment plate 40 to the flange 20a of the belly material 20 so as to be slidable in the longitudinal direction of the belly material 20, and among the pair of belly materials 20 to be joined. It is attached to at least one of these.
The slide jig 70 includes an upper L-shaped metal fitting 71 attached to the upper edge 20d of the flange 20a of the erection material 20 so as to form an upper guide groove 80 that extends in the longitudinal direction of the erection material 20 and is opened downward. It comprises a lower L-shaped metal fitting 72 attached to the lower edge 20e of the flange 20a of the abdominal material 20 so as to form a lower guide groove 81 that extends in the longitudinal direction of the abdominal material 20 and opens upward.

The L-shaped metal parts 71 and 72 have upper and lower edges 20d of the flange 20a so that one end in the longitudinal direction is positioned near the joining direction end 20f of the flange 20a and the other end extends in a direction away from the joining direction end 20f. , 20e by electric welding or the like.
The lower edge 40 b of the attachment plate 40 engages with the lower guide groove 81 formed by the lower L-shaped metal fitting 72, and the upper edge 40 c of the attachment plate 40 is formed by the upper L-shaped metal fitting 71. The attachment plate 40 is mounted on the flange 20a of the prosthetic member 20 by inserting the attachment plate 40 into a space where the L-shaped fittings 71 and 72 are opposed so as to engage with the upper guide groove 80.

According to the slide jig 70, the contact plate 40 is supported by the lower edge 40 b of the contact plate 40 being in contact with the bottom of the lower guide groove 81, while the lower edge 40 b of the contact plate 40 is supported by the lower guide groove 81. The movement of the insertion plate 40 in the direction of separating from and coming into contact with the surface of the flange 20a is restricted, and the movement of the upper edge 40c of the attachment plate 40 in the direction of coming into and out of contact with the surface of the flange 20a is restricted. The
As a result, the attachment plate 40 is mounted on the abdominal material 20 so as to be slidable in the extending direction of the guide grooves 80, 81, that is, in the longitudinal direction of the abdominal material 20 while maintaining a state substantially parallel to the flange 20 a.

  It should be noted that the flange 20a of the two anti-protrusion members 20 at the joint portion 50 is defined as a slide start point where the standby position (temporary fixing position) of the attachment plate 40 where the attachment plate 40 does not protrude from the end portion 20f of the anti-protrusion member 20 in the joining direction. The length of the slide jig 70 (L-shaped brackets 71 and 72) is set so that the attachment plate 40 can be slid between the slide start point and the slide end point when the fixed position over the slide is the slide end point. The size / arrangement is set.

Next, the joining process of the belly material 20 including the fixing process of the attachment plate 40 will be described with reference to FIGS.
First, the attachment plate 40 is slidably attached to the slide jig 70 of the first abdominal material 20-1 to which the slide jig 70 is previously attached, of the pair of abdominal materials 20 to be joined (FIG. 5 ( A): First step).

Here, the attachment position of the attachment plate 40 with respect to the slide jig 70 is a position where the attachment plate 40 does not protrude from the joining direction end portion 20f of the first belly member 20-1, and the attachment position (retreat position) is the position. The attachment plate 40 is temporarily fixed to the flange 20a with bolts (not shown) so as to be held.
Next, the first belly material 20-1 to which the attachment plate 40 is attached and the second belly material 20-2 to be joined to the first belly material 20-1 are suspended by a crane or the like. It arrange | positions on the abdominal bracket 30 so that 20f of joining direction edge parts may be faced | matched (FIG.5 (B): 2nd process).

Next, the bolt that temporarily fixed the attachment plate 40 to the flange 20a is removed, and the attachment plate 40 is manually slid from the temporary attachment position (retreat position) toward the second erection material 20-2 side, It moves to the fixed position straddling the flange 20a of the 1st erection material 20-1 and the flange 20a of the 2nd erection material 20-2 (FIG.5 (C): 3rd process).
At this time, since the attachment plate 40 is held by the slide jig 70 and guided to slide, the operator does not need to lift the attachment plate 40, and the operator slides the attachment plate 40. You only need to apply power.

In addition, prior to the operation of sliding the attachment plate 40, the operation of connecting the end plate of the first erection material 20-1 and the end plate of the second erection material 20-2 with a bolt can be performed.
When the attachment plate 40 is slid to a fixed position straddling the flange 20a of the first flank 20-1 and the flange 20a of the second flank 20-2, the attachment plate 40 is bolted to the fixed position. (FIG. 5 (D): fourth step), and the joint portion 50 between the first flank member 20-1 and the second flank member 20-2 is reinforced by the attachment plate 40.

  According to the joining method of the belly raising material 20, it is not necessary to suspend the fitting plate 40 at a fixed position with a crane or the like in the operation of fixing the fitting plate 40 to the joint portion 50 of the belly raising material 20, and Since the adjoining plate 40 can be held (temporarily fixed) so as not to protrude from the joining direction end 20f of the one provoking material 20 before the adjoining plate 40 is slid to the fixed position, The contact plate 40 does not get in the way in the operation of matching the parts. Therefore, it becomes possible to easily perform the joining work of the provoking material 20 with a simple material.

  It should be noted that the lower guide groove 81 is provided so that the sliding resistance when the attachment plate 40 is slid while being held and guided by the slide jig 70 can be reduced and the attachment plate 40 can be slid with a smaller force. As shown in FIG. 6, a plurality of rollers 82 that can rotate around a horizontal axis orthogonal to the surface of the flange 20a are provided at the bottom, and a lubricant such as grease is applied, and a material such as a fluororesin that has low friction is formed. A plate-like or tape-like material can be attached.

  Further, as shown in FIG. 7, since the length of the prosthetic material 20 in the longitudinal direction is shorter than the slide jig 70 shown in FIG. 4 and the like, the attachment plate 40 can be stably slid when used alone. The slide jig 70a that is difficult to be moved is provided at a plurality of locations in the longitudinal direction of the abdominal material 20, and the attachment plate 40 is simultaneously engaged with the plurality of slide jigs 70a. The attachment plate 40 can be slidably mounted on the flange 20a.

7 is shorter than the slide jig 70 shown in FIG. 4 or the like, but the slide jig 70a shown in FIG. 4 or the like is shorter. Similarly to 70, a lower guide groove 81 formed by the lower L-shaped metal fitting 72 and an upper guide groove 80 formed by the upper L-shaped metal fitting 71 are provided.
Further, as shown in FIG. 8, a slide jig 70 is attached to the flange 20a of the first flank 20-1, and the attachment plate 40 is attached to the slide jig 70, while the second flank of the mating partner is attached. The slide jig 70b is also attached to the material 20-2, and the attachment plate 40 is attached to the slide jig 40 at a fixed position straddling the flange 20a of the first flank 20-1 and the flange 20a of the second flank 20-2. 70 and the slide jig 70b.

  Here, if the slide jig 70 and the slide jig 70b are each configured to be able to support the attachment plate 40 independently, the attachment plate 40 is attached to the flange 20a of the first belly member 20-1. The work pattern that slides to the fixed position and the work pattern that slides to the fixed position with the attachment plate 40 attached to the flange 20a of the second abdomen 20-2 can be arbitrarily selected.

  Further, the slide jig 70 forms the upper guide groove 80 and the lower guide groove 81, but the slide jig 70c (only the lower L-shaped metal fitting 72 is formed by the slide jig 70c) that forms only the lower guide groove 81. The tool 70c) is attached to the flange 20a of the abdominal material 20, and the attachment plate 40 can be slidably attached to the flange 20a of the abdominal material 20 by this slide jig 70c.

FIGS. 9 and 10 show one mode of a slide jig 70 c that forms only the lower guide groove 81 (a slide jig 70 c formed only by the lower L-shaped metal fitting 72).
In the slide jig 70c, the lower guide groove 81 is formed by a lower L-shaped metal fitting 72 that can be attached to the lower edge of the flange 20a, and the rising height of the lower L-shaped metal fitting 72 from the bottom surface of the vertical portion 72b. However, the height is set so that the fall of the attachment plate 40 can be suppressed within a predetermined range.

That is, when the rising height from the bottom surface of the vertical portion 72b is low, the lower edge 40b of the attachment plate 40 is inserted into and supported by the lower guide groove 81, and the front edge on the upper edge 40c side of the attachment plate 40 is supported. There is a possibility that the tilting to the side becomes large, the insertion state cannot be maintained, and the contact plate 40 may drop from the lower guide groove 81.
Therefore, when the lower edge 40b of the attachment plate 40 is inserted into the lower guide groove 81 of the slide jig 70c to support the attachment plate 40, the attachment plate 40 is not tilted within a predetermined range (within an allowable range). The height of the vertical portion 72b (and the groove width of the lower guide groove 81) is adapted so that In addition, when the vertical part 72b is high and the slide jig 70c obstructs the bolting for fixing the attachment plate 40 to the joint part 50, the vertical part 72b has a notch for avoiding the bolt. Bolt insertion holes can be formed so that bolting can be performed.

  Further, in the slide jig 70c that forms only the lower guide groove 81, when the slide jig 70c is attached to only one of the flank members 20 to be joined, the attachment plate 40 is slid toward the fixed position. In addition, there is no member that supports the lower edge 40b of the attachment plate 40 located on the other side of the abdomen 20, and the slide jig 70c engages with the upper edge 40c of the attachment plate 40 to restrict movement. Therefore, the attachment plate 40 located on the other side of the abdomen 20 may fall with the sliding operation and fall off the lower guide groove 81 in some cases.

Therefore, when the slide jig 70c is used, the slide jig 70c is attached to both the flange 20a of the first erection material 20-1 and the flange 20a of the second erection material 20-2.
Further, in the example shown in FIG. 10, a plurality of slide jigs 70 c are provided by being distributed at a plurality of locations in the longitudinal direction of the ablation material 20, and the attachment plate 40 is always supported by the plurality of slide jigs 70 c. is there. However, the slide jig 70c having a length sufficient to support the attachment plate 40 in the longitudinal direction of the abdominal prosthetic material 20 is provided between the flange 20a of the first abdominal erection material 20-1 and the second abdominal erection material 20-2. One piece can be provided on both sides of the flange 20a.

In the configuration in which the slide jig 70c that forms only the lower guide groove 81 is attached to the flange 20a as described above, the slide plate 70c can be inserted into the lower guide groove 81 while the attachment plate 40 is suspended. Therefore, the work of attaching the attachment plate 40 to the belly material 20 is easy.
Even when any of the above-described slide jigs 70a, 70b, and 70c is used, the abdomen 20 is joined (fixed to the attachment plate 40) in accordance with the process shown in FIG.
Even in the slide jig 70 c that forms only the lower guide groove 81, slide resistance reducing means such as a roller that reduces the slide resistance can be provided at the bottom of the lower guide groove 81.

The above-mentioned slide jigs 70, 70a, 70b, and 70c are all attached to the flange 20a of the prosthetic member 20, but a slide jig is attached to the attachment plate 40, and the attachment plate 40 is attached by the slide jig. Can be slidably mounted on the flange 20a of the abdomen 20.
FIGS. 11 and 12 are views showing one mode of the slide jig 75 attached to the attachment plate 40.

The slide jig 75 includes a U-shaped upper guide fitting 76 that is formed in an upper guide groove 90 that extends in the longitudinal direction of the provoking material 20 and is opened downward and is attached to the upper edge 40c of the attachment plate 40; A lower guide groove 91 that extends in the longitudinal direction of the material 20 and is opened upward is formed, and is configured by a U-shaped lower guide fitting 77 that is attached to the lower edge 40 b of the attachment plate 40.
Then, the upper guide groove 90 of the upper guide fitting 76 and the lower guide groove 91 of the lower guide fitting 77 are opposed to each other in the vertical direction on the flange 20a side of the attachment plate 40, and A slide jig 75 configured with a pair of guide fittings 77 is attached to the attachment plate 40 in a distributed manner at a plurality of locations in the slide direction.

Here, by attaching the upper guide fitting 76 and the lower guide fitting 77 to the attachment plate 40 with a tap screw 79 or the like, the attachment plate 40 can be removed after being fixed to the joint portion 50 of the belly material 20 (detachable) Possible). However, the upper guide fitting 76 and the lower guide fitting 77 can be attached to the attachment plate 40 by electric welding or the like.
The lower edge 20e of the flange 20a engages with the lower guide groove 91 formed in the lower guide fitting 77, and the upper edge 20d of the flange 20a is engaged with the upper guide groove 90 formed in the upper guide fitting 76. The flange plate 20a is inserted into a space where the lower guide groove 91 and the upper guide groove 90 face each other so as to be engaged with each other, and the attachment plate 40 is attached to one flange 20a of the pair of raised members 20 to be joined. Is slidably attached.

  In other words, in a state where the attachment plate 40 is attached to the flange 20a of the provoking material 20 by the slide jig 75, the upper edge 20d of the flange 20a contacts the bottom surface of the upper guide groove 90, and the attachment plate 40 is connected to the flange 20a. It is supported by the flange 20a so as to be suspended from the upper edge 20d. Further, the upper edge 20d of the flange 20a is inserted into the upper guide groove 90, and the lower edge 20e of the flange 20a is inserted into the lower guide groove 91. The movement of the plate 40 is restricted. As a result, the splicing plate 40 is mounted on the flange 20a of the belly member 20 so as to be slidable in the extending direction of the guide grooves 90, 91, that is, in the longitudinal direction of the belly member 20, while maintaining a state substantially parallel to the flange 20a. The

Even when the attachment plate 40 is attached to the flange 20a of the belly member 20 by the slide jig 75 attached to the attachment plate 40, the attachment plate 40 is fixed to the joint portion 50 according to the process shown in FIG. .
That is, when the attachment plate 40 is mounted on the flange 20a of the prosthetic material 20 by the slide jig 75 attached to the attachment plate 40 (first step), it is temporarily fixed at a position that does not protrude from the joining direction end portion 20f. An abdominal material 20 to which the attachment plate 40 is temporarily fixed and another abdominal material 20 to be joined to the abdominal material 20 are arranged and abutted on the abdominal bracket 30 (second step).

In the state where the two abdominal prostheses 20 are abutted, the temporary attachment of the attachment plate 40 is removed, and the attachment plate 40 is integrated with the slide jig 75 and directed toward the joint portion 50 (the other erection material 20 side). It is made to slide (3rd process), it is moved to the fixing position which straddles the flange 20a of both the prosthetic materials 20, and the attachment board 40 is fixed to a fixing position with a volt | bolt etc. (4th process).
When the slide jig 75 (the upper guide metal piece 76 and the lower guide metal piece 77) is detachably attached to the attachment plate 40, the attachment plate 40 is fixed to the joint portion 50 of the belly material 20 and then the attachment plate. The process (5th process) which removes the slide jig | tool 75 from 40 can be implemented. In this case, the slide jig 75 removed from the attachment plate 40 can be attached to another attachment plate 40 and slidably mounted on the flange 20a, whereby the reuse of the slide jig 75 can be realized.

In the slide jig 75 attached to the attachment plate 40, a slide resistance reducing material such as a roller can be provided on the bottom surface of the upper guide groove 90.
In addition, when the slide jig 75 (guide fittings 76 and 77) is caught on the end plate of the belly material 20 and prevents the sliding operation of the attachment plate 40, a cutting for passing the slide jig 75 through the end plate is performed. A notch or the like can be provided to allow the attachment plate 40 to slide.

11 and 12 includes an upper guide fitting 76 and a lower guide fitting 77. As shown in FIGS. 13 and 14, the slide jig 75 includes a lower guide fitting 77. Instead, a plurality of slide jigs 78 composed only of the upper guide fittings 76 can be attached to the attachment plate 40.
In the slide jig 78 composed only of the upper guide fitting 76, the upper edge 20d of the flange 20a is inserted into the upper guide groove 90 formed in the upper guide fitting 76, and the attachment plate 40 is placed on the flange 20a. Since the attachment plate 40 can be mounted on the flange 20a by being suspended from the edge 20d, the flange 20a of the abdominal material 20 can be compared to the slide jig 75 composed of the upper guide fitting 76 and the lower guide fitting 77. The attachment plate 40 can be easily attached to the head.

However, in the slide jig 78 composed only of the upper guide fitting 76, the movement in the direction in which the lower edge 40b of the attachment plate 40 is separated from the surface of the flange 20a is not restricted, so the upper guide fitting 76 and the lower guide fitting 77 are not restricted. The slide jig 75 configured as described above has higher stability of the sliding operation of the attachment plate 40.
In the configuration shown in FIGS. 11 to 14, a plurality of slide jigs 75 and 78 are dispersed and attached to the attachment plate 40. However, the length of the single attachment plate 40 can be slidably attached to the flange 20a. Only one slide jig 75, 78 having a thickness can be attached to the attachment plate 40.
Further, in the slide jig 75 shown in FIGS. 11 and 12, the upper guide fitting 76 and the lower guide fitting 77 are separate parts, but the upper guide fitting 76 and the lower guide fitting 77 are integrally formed. The slide jig 75 can be configured.
