This mounting tool body is provided with a positioning portion, and when the base plate is arranged on the support material, the positioning portion engages with the base plate on the eaves side of the support material. Positioning of the ground plate is performed.

  For this reason, when positioning the base plate, the so-called “eave-end connection” step of connecting the eave-end side ends of a plurality of support members arranged in parallel to each other can be eliminated.

  In addition, the eaves connection as described above is performed at the building construction site, but when the support material is manufactured in advance in a factory or the like, it is possible to attach the mounting tool according to the present invention in the factory. It is. For this reason, in the building construction site of a building, the mounting process of a mounting tool is eliminated, and the above-described eaves connecting process is also eliminated. Thereby, the work man-hour in a construction site can be reduced significantly.

  Further, in the mounting tool according to the present invention, the positioning portion engages with the base plate on the eaves side of the support material. Therefore, for example, even when the field plate is installed by sliding the field plate on the support material, the positioning portion does not become an obstacle to the field plate at least until the field plate reaches the eaves side of the support material. Thereby, it is not necessary to provide a structure that can particularly accommodate the positioning part, or to provide a lock mechanism or the like for locking the positioning part. For this reason, a structure can be simplified simply and handling is also easy.

  A mounting tool according to a second aspect of the present invention is characterized in that, in the first aspect of the present invention, the positioning portion is formed integrally with the mounting tool main body.

However, the nasal concealment base plate 70 may be abutted without being fixed to the bottom wall 62. .

<Operation and Effect of First Embodiment>
Next, the operation and effect of the first embodiment will be described.

  On the roof 12 of the steel house 10, when installing the field board 68, the field board 68 is placed on the upper end side of the rafters 44, 46, 52 by a crane or the like. In this state, the base plate 68 is slid toward the eaves side of the rafters 44, 46, 52 with the inclination of the rafters 44, 46, 52. Here, the base plate 68 installed closest to the eaves side of the rafters 44, 46, 52 abuts against the positioning portion 66 by sliding the rafters 44, 46, 52. As a result, the base plate 68 on the most eaves side is prevented from sliding down any more and the base plate 68 is positioned.

  Furthermore, the field board 68 installed above the field board 68 in contact with the positioning portion 66 is also placed on the upper end side of the rafters 44, 46, 52 by a crane or the like, and is slid by the inclination of the rafters 44, 46, 52. Is done. Thereby, the edge part of the eaves side of the field board 68 arrange | positioned on the rafters 44, 46, 52 contact | abuts to the edge part on the opposite side to the eaves edge of the already positioned field board 68, and is positioned.

  In this way, the field board 68 is disposed at a predetermined position of the rafters 44, 46, 52, and is further fixed to the rafters 44, 46, 52 by a fixing member (not shown) such as a nail or a screw. 68 is installed.

  As described above, in the present embodiment, the field plate 68 is positioned by the positioning portion 66 of the mounting tool 54 coming into contact with the end portion of the field plate 68 arranged on the most eave side, so that the field plate 68 is positioned. It is possible to eliminate the so-called “eave-end connection” process for positioning the frame. In addition, as described above, when the rafters 44, 46, 52 are manufactured in a factory or the like, the mounting tool 54 having the positioning portion 66 for positioning the field board 68 is pre-arranged in the factory or the like. It is attached to. For this reason, there is no mounting process of the mounting tool 54 at the construction site of the steel house 10. Thereby, the work man-hour in a construction site can be reduced significantly.

  Furthermore, since the field board 68 is positioned by the positioning part 66 of the mounting tool 54 coming into contact with the edge part of the eave edge side of the field board 68 arranged on the most eave side, the field board 68 is positioned on the rafters 44, 46, 52. Until the base plate 68 is positioned when sliding down, the positioning portion 66 does not interfere with the base plate 68 and can smoothly slide on the rafters 44, 46, 52, and the workability is good.

  Moreover, since the positioning portion 66 does not interfere with the base plate 68 until the base plate 68 is positioned in this way, the positioning portion 66 can be accommodated, or a lock for locking the positioning portion 66 can be used. It is not necessary to provide a mechanism or the like, and a very simple structure in which the mechanism is bent from the extending portion 64 can be achieved.

  Furthermore, the positioning of the field board 68 can be easily performed only by abutting the field board 68 against the positioning portion 66 without performing operations such as position adjustment of the field board 68. Moreover, since the positioning portion 66 is bent in the thickness direction of the extending portion 64, the direction of one surface in the thickness direction is along the longitudinal direction of the rafters 44, 46, 52, and on the rafters 44, 46, 52. The end portion on the eaves side of the base plate 68 that slides down is substantially parallel to one surface in the thickness direction of the positioning portion 66. For this reason, in a state in which the base plate 68 is abutted against the positioning unit 66, the gap between the positioning unit 66 and the base plate 68 is very small, or there is a gap between the positioning unit 66 and the base plate 68. Does not occur.

  On the other hand, the vertical wall 58 has a parallelogram shape, and the side of the vertical wall 58 facing the longitudinal direction of the rafters 44, 46, 52 is along the vertical direction. For this reason, the thickness direction of the bottom wall 62 is along the horizontal direction, and one surface in the thickness direction of the nose masking base plate 70 can be reliably brought into contact with the bottom wall 62. In this way, the bottom wall 62 can be concealed by the contact of the nasal cover base plate 70 with the bottom wall 62, so that the exposure of the wearing tool 54 to the outside can be reduced. Thereby, the appearance (appearance quality) of the roof 12 and eventually the steel house 10 can be improved.

  Further, as described above, the eaves side end portions of the rafters 44, 46, 52 are covered and hidden by the nose cover base plate 70, but the nose cover base plate 70 is covered by the fixing members 72 such as screws and nails. It fixes to the edge part of the eaves side of 44,46,52.

  Here, in the state where the nasal concealment base plate 70 is arranged, it is blocked by the nasal concealment base plate 70 and the end portions of the rafters 44, 46, 52 on the eaves side cannot be directly visually recognized. However, since the positioning portion 66 that is in contact with the base plate 68 is bent upward from the tip of the extension portion 64, it is exposed to the outside and can be visually recognized from the outside.

  Since the extension part 64 in which the positioning part 66 is formed has a structure extending from the lateral wall 60 of the mounting tool main body 56 fitted to the eaves end of the rafters 44, 46, 50 to the eaves side, the positioning part 66 and rafters 44, 46, 50 correspond to each other, and as shown in FIG. 3, the fixing member 72 is driven against the nose cover base plate 70 from below the positioning portion 66, and the nose cover base plate 70 and the mounting tool When the fixing member 72 passes through the bottom wall 62 of the main body 56, the fixing member 72 is hit against the ends of the rafters 44, 46, 50 on the eaves side.

  As described above, the fixing member 72 for fixing the nasal concealment base plate 70 can be attached to the rafters 44, 46, and 50 by visually recognizing the positioning portion 66 without directly viewing the positions of the rafters 44, 46, and 50. Can be struck. For this reason, the work efficiency at the time of fixing the nose mask base plate 70 can be improved.

  Further, when the mounting tool 54 is mounted on the rafters 44, 46, 52, the mounting tool 54 can be fitted into the rafters 44, 46, 52 simply by being guided by the web 30 or the flange 32 of the rafters 44, 46, 52. The attachment tool 54 can be attached to the rafters 44, 46, 52 simply by fixing the attachment tool body 56 to the rafters 44, 46, 52 with screws or the like. For this reason, the workability for mounting the mounting tool 54 on the rafters 44, 46, 52 is good and the handling is easy.

  Further, a positioning portion 66 for positioning the base plate 68 is integrated with the mounting tool main body 56 via the extending portion 64. For this reason, the error between the rafters 44, 46, 52 and the positioning unit 66 when the mounting tool body 56 is mounted on the rafters 44, 46, 52 can be reduced, and as a result, the base plate 68 positioned by the positioning unit 66. The positional accuracy is also increased.
