The uprising member 20 is an H-shaped steel composed of two flanges 20a and one web 20b, and has a plurality of bolt holes 20c opened at equal intervals along the longitudinal direction.

The uprising member 20 is arranged on the uprising bracket 30 so that the surface of the flange 20a is a vertical plane, in other words, the flange 20a is on the front side and the back side, and extends in the horizontal direction.
In the joint portion 50 for joining the ends of the uprising members 20 by abutting each other, the splicing plates (joint plates) 40 are fixed so as to straddle the front flanges 20a of the uprising members 20, and the joint portions 50 are attached. It is reinforced by the contact plate 40.

The splicing plate 40 is provided with a plurality of bolt holes 40a corresponding to the arrangement of the bolt holes 20c opened in the upholstery material 20, and the bolt holes 20c of the upholstery material 20 of the splicing plate 40 are formed. The position where the bolt holes 40a overlap is a fixed position, and the splicing plate 40 is fixed to a position that straddles both flanges 20a to be abutted by the bolts inserted into the bolt holes 20c and 40a.

The backing material 60 is interposed in the gap between the flange 20a on the back surface side (the mountain retaining wall 10 side) of the uprising material 20 and the mountain retaining wall 10, and earth pressure is applied via the backing material 60 to the uprising material 20. It is configured to be transmitted to.
Further, the uprising member 20 is assembled with a cut beam, a hammered beam, etc., which are not shown.

Next, the step of fixing the splicing plate 40 to the joint part 50 in the step of butting and joining the ends of the uprising material 20 will be described in detail.
3 and 4 show one embodiment of a slide jig 70 used in the step of fixing the splicing plate 40 to the joint portion 50.

The slide jig 70 is a jig for mounting the splicing plate 40 on the flange 20 a of the uprising member 20 so as to be slidable in the longitudinal direction of the uprising member 20. Attached to at least one of the.
The slide jig 70 includes an upper L-shaped metal fitting 71 attached to the upper edge 20d of the flange 20a of the upholstery material 20 so as to form an upper guide groove 80 that extends in the longitudinal direction of the upholstery material 20 and is opened downward. The lower L-shaped metal fitting 72 is attached to the lower edge 20e of the flange 20a of the upholstery material 20 so as to form a lower guide groove 81 extending in the longitudinal direction of the upholstery material 20 and opened upward.

The L-shaped metal fittings 71, 72 have upper and lower edges 20d of the flange 20a such that one end in the longitudinal direction thereof is located 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 40b of the splicing plate 40 is engaged with the lower guide groove 81 formed by the lower L-shaped metal fitting 72, and the upper edge 40c of the splicing plate 40 is formed by the upper L-shaped metal fitting 71. By inserting the splicing plate 40 into the space where the L-shaped metal fittings 71 and 72 face each other so as to engage with the upper guide groove 80, the splicing plate 40 is attached to the flange 20 a of the uprising material 20.

According to the slide jig 70, the lower edge 40b of the splicing plate 40 is supported by abutting the bottom portion of the lower guide groove 81, while the lower edge 40b of the splicing plate 40 is aligned with the lower guide groove 81. Movement of the upper edge 40c of the splicing plate 40 inserted into the upper guide groove 80 is restricted so that the movement of the upper edge 40c of the splicing plate 40 is restricted. It
As a result, the splicing plate 40 is slidably attached to the uprising member 20 in the extending direction of the guide grooves 80, 81, that is, in the longitudinal direction of the uprising member 20 while maintaining the parallel state with the flange 20a.

It should be noted that the flange 20a of both belly risers 20 at the joint section 50 is set at the slide start point at the standby position (temporary fixing position) of the splice plate 40 where the splice plate 40 does not project from the end portion 20f in the joining direction of the riser 20. The length of the slide jig 70 (L-shaped metal fittings 71, 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 straddling the ridge is the slide end point. S/arrangement is set.

Next, the joining process of the uprising material 20 including the fixing process of the splicing 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 uprising member 20-1 to which the slide jig 70 is previously attached, out of the pair of uprising members 20 to be joined (see FIG. A): First step).

Here, the attachment position of the attachment plate 40 with respect to the slide jig 70 is a position at which the attachment plate 40 does not project from the end portion 20f of the first uprising member 20-1 in the joining direction, and the attachment position (the retracted position) is set. The attachment plate 40 is temporarily fixed to the flange 20a with bolts (not shown) so as to hold it.
Next, the first upholstery material 20-1 to which the attachment plate 40 is attached and the second upholstery material 20-2 to be joined to the first upholstery material 20-1 are hung by a crane or the like, and It is arranged on the uprising bracket 30 so that the end portions 20f in the joining direction are abutted against each other (FIG. 5(B): second step).

Next, the bolts that have temporarily fixed the splicing plate 40 to the flange 20a are removed, and the splicing plate 40 is manually slid from the temporary fixing position (retracting position) toward the second uprising member 20-2 side. It is moved to a fixed position across the flange 20a of the first upholstery material 20-1 and the flange 20a of the second upholstery material 20-2 (FIG. 5C: third step).
At this time, since the splicing plate 40 is held by the slide jig 70 and the sliding movement is guided, the operator does not need to lift the splicing plate 40, and the worker slides the splicing plate 40. All you have to do is apply force.

Before the work of sliding the attachment plate 40, the work of connecting the end plate of the first upholstery material 20-1 and the end plate of the second upholstery material 20-2 with bolts can be performed.
When the attachment plate 40 is slid to a fixed position across the flange 20a of the first upholstery member 20-1 and the flange 20a of the second upholstery member 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 upholstery material 20-1 and the second upholstery material 20-2 is reinforced by the splicing plate 40.

According to the joining method of the upholstery material 20, in the work of fixing the splice plate 40 to the joint portion 50 of the upholstery material 20, it is not necessary to suspend the splice plate 40 at a fixed position with a crane, and Before sliding the splicing plate 40 to the fixed position, the splicing plate 40 can be held (temporarily fixed) in a state in which it does not project from the end portion 20f in the joining direction of one of the plastering members 20. The attachment plate 40 does not interfere with the work of abutting the parts. Therefore, the work of joining the uprising members 20 can be easily performed with a simple material.

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

Further, as shown in FIG. 7, since the length of the uprising member 20 in the longitudinal direction is shorter than that of the slide jig 70 shown in FIG. The slide jigs 70a, which are difficult to perform, are provided at a plurality of locations in the longitudinal direction of the upholstery material 20, and the attachment plate 40 is simultaneously engaged with the multiple slide jigs 70a. The attachment plate 40 can be slidably attached to the flange 20a.

The slide jig 70a shown in FIG. 7 has a shorter length in the longitudinal direction of the uprising member 20 than the slide jig 70 shown in FIG. 4 or the like, but the slide jig 70a shown in FIG. Similar to 70, the lower guide groove 81 formed by the lower L-shaped metal fitting 72 and the upper guide groove 80 formed by the upper L-shaped metal fitting 71 are provided.
Further, as shown in FIG. 8, the slide jig 70 is attached to the flange 20a of the first uprising member 20-1, and the attachment plate 40 is attached to the slide jig 70, while the second uprising member of the joining partner is attached. The slide jig 70b is also attached to the material 20-2, and the attachment plate 40 slides at the fixed position across the flange 20a of the first uprising material 20-1 and the flange 20a of the second uprising material 20-2. 70 and the slide jig 70b may be supported.

Here, if the slide jig 70 and the slide jig 70b are respectively configured to support the attachment plate 40 independently, the attachment plate 40 is attached to the flange 20a of the first uprising member 20-1. It is possible to arbitrarily select a work pattern in which the attachment plate 40 is attached to the flange 20a of the second uprising member 20-2 and then slid to the fixed position.

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

9 and 10 show one mode of a slide jig 70c that forms only the lower guide groove 81 (a slide jig 70c that is 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 attached to the lower edge of the flange 20a. The lower L-shaped metal fitting 72 has a rising height from the bottom surface of the vertical portion 72b. The height is set to a height that can prevent the splicing plate 40 from falling 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 splicing plate 40 is inserted in the lower guide groove 81 and supported, and the front edge of the upper edge 40c of the splicing plate 40 is in front. There is a possibility that the inclining to the side becomes large, and the insertion state cannot be maintained, and the splicing plate 40 falls off 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 inclination of the attachment plate 40 is 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 portion 72b is high and the slide jig 70c interferes with bolt fastening for fixing the splicing plate 40 to the joint portion 50, a notch or a notch for avoiding the bolt is formed in the vertical portion 72b. A bolt insertion hole can be formed so that bolt tightening can be performed.

Further, in the slide jig 70c forming only the lower guide groove 81, when the slide jig 70c is attached to only one of the uprising members 20 to be joined, when the attachment plate 40 is slid toward the fixed position. In addition, there is no member that supports the lower edge 40b of the splicing plate 40 located on the side of the other uprising material 20, and the slide jig 70c engages with the upper edge 40c of the splicing plate 40 to regulate the movement. Since it is not provided, the splicing plate 40 located on the side of the other uprising member 20 may fall along with the sliding operation and fall off from the lower guide groove 81.

Therefore, when the slide jig 70c is used, the slide jig 70c is attached to both the flange 20a of the first upholstery material 20-1 and the flange 20a of the second upholstery material 20-2.
Further, in the example shown in FIG. 10, a plurality of slide jigs 70c are dispersed in a plurality of locations in the longitudinal direction of the uprising material 20, and a plurality of slide jigs 70c are always provided to support the attachment plate 40. is there. However, the slide jig 70c having a length sufficient to support the splicing plate 40 in the longitudinal direction of the upholstery material 20 is installed between the flange 20a of the first upholstery material 20-1 and the second upholstery material 20-2. One can be provided on both 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 splicing plate 40 can be inserted into the lower guide groove 81 of the slide jig 70c in a suspended state. Therefore, the work of attaching the attachment plate 40 to the uprising material 20 is easy.
In any of the slide jigs 70a, 70b, 70c described above, the uprising member 20 is joined (fixing the splicing plate 40) according to the process shown in FIG.
Even in the slide jig 70c forming only the lower guide groove 81, a slide resistance reducing means such as a roller for reducing the slide resistance can be provided at the bottom of the lower guide groove 81.

By the way, the slide jigs 70, 70a, 70b, 70c described above are all attached to the flange 20a of the uprising member 20, but the slide jig is attached to the attachment plate 40 side, and the attachment plate 40 is attached by the slide jig. Can be slidably attached to the flange 20a of the uprising member 20.
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 metal fitting 76, which has an upper guide groove 90 extending in the longitudinal direction of the uprising member 20 and opened downward, and which is attached to the upper edge 40c of the splicing plate 40, and an uprising member. A lower guide groove 91 extending in the longitudinal direction of the material 20 and opened upward is formed, and is configured by a U-shaped lower guide metal fitting 77 attached to the lower edge 40b of the splicing plate 40.
Then, the upper guide groove 90 of the upper guide metal fitting 76 and the lower guide groove 91 of the lower guide metal fitting 77 are arranged to face each other in the vertical direction on the flange 20a side of the splicing plate 40. The slide jigs 75, which are paired with the guide fittings 77, are attached to the splicing plate 40 while being dispersed at a plurality of positions in the sliding direction.

Here, by attaching the upper guide metal fitting 76 and the lower guide metal fitting 77 to the splicing plate 40 with tap screws 79 or the like, the splicing plate 40 can be detached after being fixed to the joint portion 50 of the uprising material 20 (detachment/removal). Possible). However, the upper guide metal fitting 76 and the lower guide metal fitting 77 may 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 fits into the upper guide groove 90 formed in the upper guide fitting 76. The flange 20a is inserted into a space where the lower guide groove 91 and the upper guide groove 90 face each other so as to engage with each other, and the splice plate 40 is attached to one flange 20a of the pair of uprising members 20 to be joined. To be slidable.

That is, when the attachment plate 40 is attached to the flange 20a of the uprising member 20 by the slide jig 75, the upper edge 20d of the flange 20a abuts the bottom surface of the upper guide groove 90, and the attachment plate 40 is attached 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 attachment plate 40 is slidably mounted on the flange 20a of the uprising member 20 in the extending direction of the guide grooves 90, 91, that is, the longitudinal direction of the uprising member 20 while keeping the parallel state with the flange 20a. It

Even when the attachment plate 40 is attached to the flange 20a of the uprising member 20 by the slide jig 75 attached to the attachment plate 40, the attachment plate 40 is fixed to the joint part 50 according to the process shown in FIG. ..
That is, when the attachment plate 40 is attached to the flange 20a of the uprising member 20 by the slide jig 75 attached to the attachment plate 40 (first step), the attachment plate 40 is temporarily fixed to a position that does not protrude from the joining direction end 20f, The uprising material 20 to which the splicing plate 40 is temporarily fixed and another uprising material 20 to be joined to the uprising material 20 are placed on the uprising bracket 30 and abutted against each other (second step).

With the two upholstery members 20 butted against each other, the temporary fixing of the splicing plate 40 is removed, and the splicing plate 40 is integrated with the slide jig 75 so that the splicing plate 40 faces the joint portion 50 (on the side of the other upholstery member 20). The sliding member is slid (third step), moved to a fixed position across the flanges 20a of both uprising members 20, and the splicing plate 40 is fixed to the fixed position with a bolt or the like (fourth step).
When the slide jig 75 (the upper guide metal fitting 76 and the lower guide metal fitting 77) is detachably attached to the splicing plate 40, the splicing plate 40 is fixed to the joint portion 50 of the uprising material 20 and then the splicing plate. The step of removing the slide jig 75 from the 40 (fifth step) can be performed. In this case, the slide jig 75 removed from the attachment plate 40 can be attached to another attachment plate 40 and slidably attached to 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.
Further, when the slide jig 75 (guide fittings 76, 77) is caught on the end plate of the uprising member 20 to prevent the sliding movement of the splicing plate 40, a cut for allowing the slide jig 75 to pass through the end plate. A notch or the like can be provided to allow the splicing plate 40 to slide.

The slide jig 75 shown in FIGS. 11 and 12 is composed of an upper guide metal fitting 76 and a lower guide metal fitting 77, but as shown in FIG. 13 and FIG. Instead, a plurality of slide jigs 78 configured only by the upper guide metal fittings 76 can be attached to the attachment plate 40.
In the slide jig 78 composed only of the upper guide metal fitting 76, the upper edge 20d of the flange 20a is inserted into the upper guide groove 90 formed in the upper guide metal fitting 76 so that the attachment plate 40 is placed on the flange 20a. Since the splicing plate 40 can be attached to the flange 20a by suspending it from the edge 20d, the flange 20a of the uprising member 20 is larger than that of the slide jig 75 including the upper guide metal fitting 76 and the lower guide metal fitting 77. The attachment plate 40 can be easily attached to the attachment plate 40.

However, in the slide jig 78 configured only by the upper guide metal fitting 76, the movement of the lower edge 40b of the abutting plate 40 away from the surface of the flange 20a is not restricted, so the upper guide metal fitting 76 and the lower guide metal fitting 77 are not restricted. The slide jig 75 configured by means of is more stable in the sliding operation of the attachment plate 40.
In addition, 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, but only one attachment plate 40 is slidably attached to the flange 20a. Only one slide jig 75, 78 having a thickness can be attached to the attachment plate 40.
In the slide jig 75 shown in FIGS. 11 and 12, the upper guide metal fitting 76 and the lower guide metal fitting 77 are separate components, but the upper guide metal fitting 76 and the lower guide metal fitting 77 are integrally formed. Thus, the slide jig 75 can be configured.

Although the content of the present invention has been specifically described with reference to the preferred embodiments, it is obvious that those skilled in the art can adopt various modifications based on the basic technical idea and teaching of the present invention. is there.
The slide jigs 70a, 70b, 70c, 75, 78 described above are applied to the attachment plate 40 for reinforcing the joint portion 50 of the uprising material 20, but the slide jigs 70a, 70b, 70c, 75, The H-section steel to which 78 is applied is not limited to the uprising member 20, and can be widely applied to a splicing plate that reinforces the joint section of the H-section steel that extends in the horizontal direction such that the flange surface becomes the vertical plane. Is.

Further, for example, a slide jig that forms the lower guide groove is attached to the flange 20a of the uprising member 20 (H-shaped steel), while a slide jig that forms the upper guide groove is attached to the splicing plate 40 and the flange 20a.
