Japanese Patent Laid-Open No. 11-100905

  However, since the conventional body edge and body edge receiving member are formed in a substantially rectangular hat shape in which the top plate portion, the side plate portion and the fixed plate portion are bent at right angles, the body edge is fixed to the body edge receiver. There is a problem that the top plate portion, the side plate portion, and the fixed plate portion are easily bent from each other when the load is applied from the outer wall or the like.

  By the way, such screwing is generally performed using an impact wrench. However, it is difficult to screw a screw at right angles to the fixed plate with an impact wrench. Depending on how the operator applies force, the screw may be screwed into the fixed plate at an angle, or the fixed plate may be lifted. The trouble of doing occurs. Therefore, it is conceivable to restrict the screwing direction of the screw by bringing the attachment of the impact wrench into contact with or close to the side plate portion of the trunk edge. However, when the conventional body edge is used, the side plate portion and the attachment are in surface contact with each other, so that the interference of the side plate portion with respect to the rotation of the attachment becomes large, and it is difficult to properly screw the screw into the fixed plate portion.

  Therefore, an object of the present invention is to provide a trunk edge, a trunk edge receiving member, and a base member that can suppress deformation.

  A trunk edge according to the present invention is a trunk edge attached to a trunk edge receiving member, and a top plate part, a pair of side plate parts bent at an acute angle on the same surface side at both end edges of the top plate part, and each And a pair of fixed plate portions that are bent outward at an acute angle at the edge of the side plate portion, are substantially parallel to the top plate portion, and are fixed to the trunk edge receiving member.

  According to the trunk edge according to the present invention, the pair of side plate portions is inclined back so as to enter the inside toward the top plate portion side, whereby the pair of side plate portions are pulled back inward with respect to the force of expanding the pair of side plate portions. A strong restoring force is applied. For this reason, when a trunk edge is fixed to a trunk edge receiving member, or when a weight is received from an outer wall attached to the trunk edge, it is possible to prevent the trunk edge from being greatly deformed.

  In this case, it is preferable that the fixing plate portion is fixed to the trunk edge receiving member by screwing. Thus, by fixing the fixing plate portion and the trunk edge receiving member with screws, the trunk edge can be reliably fixed to the trunk edge receiving member. Moreover, since the pair of side plate portions are formed so as to enter the inner side toward the top plate portion side, the tool and the side plate portion only contact with each other even if the tool for screwing the screw is brought into contact with the side plate portion. do not do. As a result, since the interference of the side plate portion with respect to the rotation of the tool can be minimized, the screw can be screwed in while the tool is close to or in contact with the side plate portion, and the side plate portion can function appropriately as a tool guide. it can.

  Furthermore, a guide groove for positioning the screw is formed in the fixed plate portion, and the guide groove fixes the screw when the screw tip is fitted and the screw is arranged at right angles to the fixed plate portion. It is preferable that the tool to be screwed into the plate portion is formed at a position in contact with or close to the side plate portion. When the guide groove is formed in the fixed plate portion in this way, the screw can be disposed at a right angle with respect to the fixed plate portion by fitting the tip of the screw into the guide groove and bringing the tool into contact with or close to the side plate portion. Thereby, since the guide function of the side plate portion is effectively exhibited, it is possible to further reduce work mistakes such as screwing in a state where the screw is inclined with respect to the fixed plate portion.

  A trunk edge receiving member according to the present invention is a trunk edge receiving member to which a trunk edge is attached by being attached to a building frame, and a bottom plate part in which a bolt hole into which a bolt fixed to the building frame is screwed is formed, and a bottom plate A pair of side plate portions bent at an acute angle on the same surface side at both end edges of the portion, and a pair of side plate portions bent at an acute angle outward at the edge of each side plate portion so as to be substantially parallel to the bottom plate portion and to be fixed to the body edge And a fixed plate portion.

  According to the trunk edge receiving member according to the present invention, the pair of side plate portions is inward with respect to the force of spreading the pair of side plate portions by inclining the pair of side plate portions toward the bottom plate portion side so as to enter the inside. A strong restoring force is applied. Therefore, when the trunk edge is fixed to the trunk edge receiving member or when a load is applied from the trunk edge, it is possible to prevent the trunk edge receiving member from being greatly deformed even if a load is applied to the trunk edge receiving member. .

  The base member according to the present invention includes any one of the above-described trunk edges and the above-described trunk edge receiving member.

  According to the base member according to the present invention, the trunk edge receiving member and the side plate portions of the trunk edge are inclined so as to enter the inner side toward the bottom plate part side and the top plate part side, respectively. Can be suppressed. Also, since the space between the bottom plate portion of the trunk edge receiving member where the bolt hole is formed and the top plate portion of the trunk edge can be sufficiently secured by the side edge portion of the trunk edge receiving member and the trunk edge, the bolt from the bolt hole By adjusting the screwing amount, the level adjustment width of the base member can be increased.

  In this case, it is preferable that the trunk edge receiving member and the trunk edge are fixed in an intersecting manner with the bolt hole as an intersection. When the trunk edge receiving member and the trunk edge are arranged in this manner, the bolt is screwed between the pair of side plate portions by causing the tip of the bolt screwed into the bolt hole to reach the trunk edge. Interpolated. As a result, even if the trunk edge and the trunk edge receiving member are deformed due to a load or the like, the trunk edge and the trunk edge receiving member are greatly deformed in order to receive the trunk edge and the trunk edge receiving member where the bolt is deformed. It is possible to prevent the outer wall from proceeding to breakage.

  According to the present invention, deformation can be suppressed.

The bottom plate portion 12 and the fixed plate portions 14a and 14b are substantially parallel (including parallel). Further, the separation distance between the side plate portion 13a and the side plate portion 13b is narrowed from the bottom plate portion 12 toward the fixed plate portions 14a and 14b, and the separation distance between the fixed plate portion 14a and the fixed plate portion 14b is the bottom plate portion. The dimension is narrower than 12. Further, the thickness of the trunk edge receiving member 6 is the same as that of the trunk edge 7 or thicker than the trunk edge 7 from the viewpoint of securing the holding strength of the trunk edge 7.

  The bolt hole 11 is tapped to match the thread of the bolt 5 so that the bolt 5 can be screwed in. And as for the baseplate part 12, the circumference | surroundings of the bolt hole 11 are thicker than others, and the length of the bolt hole 11 is extended. Thereby, since the joining area of the volt | bolt 5 and the volt | bolt hole 11 increases, when the volt | bolt 5 is screwed in the volt | bolt hole 11, the retention strength of the trunk edge receiving member 6 with respect to the volt | bolt 5 can be improved.

  The bolt hole 11 can be formed, for example, by pulling the bottom plate portion 12 downward by punching. At that time, by leaving a part without completely shearing the part extracted from the bottom plate part 12, the part extracted from the bottom plate part 12 hangs below the bottom plate part 12. It is possible to simultaneously increase the length of the bolt hole 11 by making the periphery of the bolt hole 11 thick.

  Note that there may be only one bolt hole 11 or a plurality of bolt holes 11. From the viewpoint of stability of the trunk edge receiving member 6, when there is one bolt hole 11, the bolt hole 11 is formed at the center of the bottom plate portion 12, and when there are a plurality of bolt holes 11, the bolt hole 11 is formed at the bottom plate portion 12. It is preferable to form them at regular intervals.

  The side plate portions 13a and 13b are arranged on the bottom plate portion 12 side (fixed plate portions 14a and 14b) with respect to a surface perpendicular to the bottom plate portion 12 (fixed plate portions 14a and 14b) (a surface parallel to the height direction of the trunk edge receiving member 6). 14b side) as long as it is inclined to fall down, and the inclination angle is not limited.

  As shown in FIGS. 5 and 6, the trunk edge 7 has a substantially trapezoidal hat shape with a cross section opened to the lower side, and is formed by bending one metal plate at four locations, for example. . That is, the trunk edge 7 includes a long and narrow rectangular top plate portion 15 to which the outer wall is attached, and a pair of long and narrow rectangular side plate portions 16a formed by bending at an acute angle downward at both ends in the width direction of the top plate portion 15. 16b and a pair of elongated rectangular shapes that are bent at an acute angle outward (on the opposite side to the direction in which the side plate portions 16a and 16b are bent with respect to the top plate portion 15) at the front end edges in the width direction of the side plate portions 16a and 16b. Fixed plate portions 17a and 17b. In this embodiment, the long side direction (left and right direction in FIG. 6A) of the top plate part 15, the side plate parts 16a and 16b, and the fixed plate parts 17a and 17b is the length direction, and the short side direction is the width. The direction.

  The angle formed by the top plate portion 15 and the side plate portions 16a and 16b and the angle formed by the side plate portions 16a and 16b and the fixed plate portions 17a and 17b are substantially the same (including the same) angle. The top plate portion 15 and the fixed plate portions 17a and 17b are substantially parallel (including parallel). Further, the separation distance between the side plate portion 16a and the side plate portion 16b becomes narrower from the top plate portion 15 toward the fixed plate portions 17a and 17b, and the separation distance between the fixed plate portion 17a and the fixed plate portion 17b is The dimensions are narrower than the width of the plate portion 15.

  The side plate portions 16a and 16b are arranged on the top plate portion 15 side (fixed plate portions 17a and 17b) with respect to a surface perpendicular to the top plate portion 15 (fixed plate portions 17a and 17b) (a surface parallel to the height direction of the trunk edge 7). 17b side), and the inclination angle is not limited. However, from the viewpoint of workability and shape retention strength of the body edge 7, the inclination angle is preferably 3 to 30 °, and more preferably 7 to 20 °. In the figure, the inclination angle is 15 °.

  The fixing plate portions 17 a and 17 b are portions that are fixed to the fixing plate portions 14 a and 14 b of the trunk edge receiving member 6 with screws 8. For this reason, it is preferable that the fixing plate portions 17a and 17b have a necessary and sufficient width for screwing the screws 8 from the viewpoint of workability.

  Guide grooves 18 for positioning the screws 8 are formed in the fixed plate portions 17a and 17b. The guide groove 18 is a V-groove extending linearly in the length direction, and the screw 8 can be positioned by fitting the tip of the screw 8.

  By the way, an impact wrench (not shown) of a rotary tool is used to screw the screws 8 into the fixed plate portions 17a and 17b and fix the fixed plate portions 17a and 17b to the fixed plate portions 14a and 14b. Specifically, first, the adapter 20 (see FIG. 7) of the impact wrench is fitted into the head of the screw 8, the tip of the screw 8 is applied to the fixing plate portions 17a and 17b, and the screw 8 is fixed to the fixing plate portions 17a and 17b. Hold at a right angle to. The adapter 20 is also a part of the rotary tool. In this state, the impact wrench is driven and rotated while giving impact (blow) to the screw 8. As a result, the screws 8 are screwed into the fixing plate portions 17a and 17b and the fixing plate portions 14a and 14b, and the fixing plate portions 17a and 17b and the fixing plate portions 14a and 14b are fixed.

  Therefore, as shown in FIG. 7, the guide groove 18 is an adapter in which the head of the screw 8 is fitted when the tip of the screw 8 is fitted and the screw 8 is disposed at right angles to the fixing plate portions 17a and 17b. 20 is formed in the position which contact | abuts or adjoins to side plate part 16a, 16b. At this time, since the side plate portions 16a and 16b have a shoulder portion 19 that is a connecting portion with the top plate portion 15 protruding toward the fixed plate portions 17a and 17b (outside), the adapter 20 contacts the side plate portions 16a and 16b. Even if they come into contact, the adapter 20 and the side plate portions 16a and 16b come into contact with each other only at points in the shoulder portion 19.

  The guide groove 18 formed at such a position has a guide function for screwing the screw 8 at a right angle with respect to the fixing plate portions 17a and 17b when the adapter 20 contacts or approaches the shoulder portion 19. From the viewpoint of effectively exhibiting the guide function of the guide groove 18 as described above, the guide groove 18 is inserted into the screw 8 when the tip of the screw 8 is fitted and the screw 8 is disposed at right angles to the fixing plate portions 17a and 17b. It is preferable that the distance between the adapter 20 of the impact wrench fitted with the head of 8 and the side plate portions 16a and 16b is in a range of 0 to 2 mm, and this distance is in a range of 0 to 1 mm. More preferably, it is formed. Note that the distance between the adapter 20 and the side plate portions 16a and 16b being 0 mm means that the adapter 20 is in contact with the side plate portions 16a and 16b.

  8A and 8B are diagrams showing a connection state of the trunk edge using the joint member. FIG. 8A is a top view showing a state in which two trunk edges are connected by the joint member, and FIG. It is the perspective view which showed the state which inserted the edge. FIG. 9 is a plan view of the joint member, where (a) is a top view, (b) is a front view, and (c) is a side view.

  As shown in FIGS. 8 and 9, the joint member 9 inserts the fixing plate portions 17a and 17b of the two trunk edges 7 so as to sandwich the fixing plate portions 17a and 17b. 7, the two body edges 7 are connected in the longitudinal direction by screwing the fixing plate portions 17a and 17b. The joint member 9 has a thin C-shaped section with an opening on the upper side, and is configured by bending one rectangular metal plate at four locations. That is, the joint member 9 includes a rectangular support plate portion 21, a pair of elongated rectangular side plate portions 22a and 22b that are bent upward at both edges in the width direction of the support plate portion 21, and each side plate portion 22a, A pair of elongated locking plate portions 23a and 23b that are bent and formed on the inner edge (the same side as the direction in which the side plate portions 22a and 22b are bent with respect to the support plate portion 21) at the leading edge in the width direction of 22b; Is provided. In the present embodiment, the long side direction (vertical direction in FIG. 9A) of the side plate portions 22a and 22b and the locking plate portions 23a and 23b is the length direction, and the short side direction is the width direction.

  The support plate portion 21 is a portion that supports the fixed plate portions 17a and 17b of the trunk edge 7 from below. For this reason, the width of the support plate portion 21 is equal to the width of the trunk edge 7 (the length from the outer edge end in the width direction of the fixed plate portion 17a to the outer edge end in the width direction of the fixed plate portion 17b) or from the width of the trunk edge 7. The dimensions are slightly wider.

  The side plate portions 22a and 22b connect the support plate portion 21 and the locking plate portions 23a and 23b to be substantially parallel (including parallel), and between the support plate portion 21 and the locking plate portions 23a and 23b. 7 is a portion for securing a space (space) for sandwiching the seven fixing plate portions 17a and 17b. For this reason, the width of the side plate portions 22 a and 22 b (the rising height with respect to the support plate portion 21) is the same as the thickness of the body edge 7 or slightly wider than the thickness of the body edge 7. The side plate portions 22a and 22b can be connected to the support plate portion 21 and the locking plate portions 23a and 23b if the support plate portion 21 and the locking plate portions 23a and 23b can be connected substantially in parallel (including parallel). On the other hand, it may be bent at any angle. The side plate portions 22a and 22b may have any shape as long as a predetermined space can be secured between the support plate portion 21 and the locking plate portions 23a and 23b. For example, the side plate portions 22a and 22b can be easily bent. In consideration of this, the support plate portion 21 may be curved to the locking plate portions 23a and 23b. In this case, the bending of the side plate portions 22a and 22b with respect to the support plate portion 21 and the bending of the locking plate portions 23a and 23b with respect to the side plate portions 22a and 22b can be performed at once.

  The locking plate portions 23a and 23b are portions where the fixing plate portions 17a and 17b are pressed from above and the screws 10 are screwed. For this reason, the width of the locking plate portions 23a and 23b is narrower than the width of each of the fixed plate portions 17a and 17b, and from the viewpoint of workability, has a necessary and sufficient size for screwing the screw 10. It is preferable.

  Screw holes 24 for positioning the screws 10 screwed into the fixing plate portions 17a and 17b are formed in the locking plate portions 23a and 23b. In FIG. 9, two screw holes 24 are formed in each of the locking plate portions 23a and 23b, but only one may be formed, or three or more may be formed. Since the screw hole 24 is formed for the purpose of positioning the screw 10, it is not particularly necessary if the positioning of the screw 10 is unnecessary.

  Next, the construction method of the base member 1 will be described.

  First, the trunk edge receiving member 6 is attached to each bolt 5 fixed to the housing 2. This process is performed by fitting the bolt hole 11 of the trunk edge receiving member 6 to the bolt 5 and rotating the trunk edge receiving member 6 with respect to the bolt 5. Then, by adjusting the amount of rotation of the trunk edge receiving member 6 with respect to the bolt 5, each of the trunk edge receiving members 6 is arranged so that the fixing plate portions 14a, 14b of all the trunk edge receiving members 6 are arranged on the same plane. Adjust the level. In that case, the front-end | tip of the volt | bolt 5 is protruded from the fixing plate parts 14a and 14b of the trunk edge receiving member 6. FIG. However, the protruding length of the bolt 5 with respect to the fixing plate portions 14a and 14b is from the height o of the trunk edge 7 so that the bolt 5 does not get in the way when the trunk edge 7 is attached to the trunk edge receiving member 6. The length is made shorter than the length obtained by subtracting the thickness j.

  Next, in order to make the trunk edge 7 have a desired length, a plurality of trunk edges 7 are connected using the joint member 9. In this step, first, the fixing plate portions 17a and 17b of the body edge 7 to be connected are inserted between the support plate portion 21 and the locking plate portions 23a and 23b in the joint member 9 from both sides.

In this step, first, the fixing plate portions 17 a and 17 b of the trunk edge 7 are overlapped with the fixing plate portions 14 a and 14 b of the trunk edge receiving member 6. At that time, the bolt 5 protruding from the trunk edge receiving member 6 is inserted between the side plate portion 13a and the side plate portion 13b of the trunk edge receiving member 6, and between the side plate portion 16a and the side plate portion 16b of the trunk edge 7. The barrel receiving member 6 and the barrel edge are intersected with the axis (the position of the bolt hole 11) of the bolt 5 protruding from the barrel receiving member 6 as an intersection so that the bolt 5 protruding from the barrel receiving member 6 is inserted therebetween. 7 and overlap each other at a substantially right angle. Then, the fixed plate portions 14a and 14b and the fixed plate portions 17a and 17b are screwed using an impact wrench. Thereby, the trunk edge receiving member 6 and the trunk edge 7 are fixed in an intersecting manner with the bolt hole 11 as an intersection. At that time, the impact wrench is driven while the tip of the screw 8 is fitted in the guide groove 18 formed in the fixing plate portions 17a and 17b, and the adapter 20 in which the head of the screw 8 is fitted is brought into contact with or close to the shoulder portion 19. By doing so, the screw 8 is screwed into the fixing plate portions 17a and 17b.

  Thus, the bolt 5 is inserted between the pair of side plate portions 13 a and 13 b in the trunk edge receiving member 6, and the bolt 5 is inserted between the pair of side plate portions 16 a and 16 b in the trunk edge 7. The base member 1 to which the body edge receiving member 6 and the body edge 7 are screwed (screwed) is attached to the bolt 5.

  Here, as a comparative example, a conventional hat having a substantially rectangular hat shape in which the connecting portions of the top plate portion, the side plate portion, and the fixed plate portion are bent at right angles is used, and the drum edge is screwed to the drum edge receiving member. A state to be performed will be described.

  FIG. 10 is a view showing a state in which a screw is screwed into the body edge of the comparative example. As shown in FIG. 10A, the operator usually tries to screw the screw into the fixed plate portion while holding the screw perpendicular to the fixed plate portion. However, as shown in FIG. 10 (b), depending on how the operator applies the force, the screw may be screwed diagonally or the fixed plate portion may be lifted. In addition, the body edge having a substantially rectangular hat shape in cross section is restored to pull back the side plate parts inward with respect to the force of spreading the side plate parts 16a and 16b outward as compared to the body edge having a substantially trapezoidal cross section in the present embodiment. Since the force is small, as shown in FIG. 10 (c), the trunk edge may be fixed to the trunk edge receiver in a deformed state in which the side plate portion spreads.

  On the other hand, in this embodiment, as shown in FIG. 7, since the shoulder portion 19 serves as a guide for the adapter 20, the screw 8 is fixed in a state where the screw 8 is held perpendicular to the fixing plate portions 17a and 17b. It can be screwed into the plate portions 17a and 17b. In addition, as shown in FIG. 11, the trunk edge 7 has a substantially trapezoidal cross section, so that a strong restoring force that pulls the side plate portions 16a and 16b inwardly acts on the force that spreads the side plate portions 16a and 16b outward. To do. For this reason, even if the screw 8 is screwed diagonally, the deformation of the trunk edge 7 can be suppressed, and even if a strong external force acts on the trunk edge 7, the deformation of the trunk edge 7 can be suppressed.

  As described above, according to the present embodiment, the side plate portions 16a and 16b of the trunk edge 7 are inclined so as to enter the inner side toward the top plate portion 15 side, so that the side plate portions 16a and 16b can be expanded. A strong restoring force that pulls the side plate portions 16a and 16b inward acts. For this reason, when the trunk edge 7 is fixed to the trunk edge receiving member 6 or when a weight is applied from an outer wall attached to the trunk edge 7, it is possible to prevent the trunk edge 7 from being greatly deformed.

  Similarly, the side plate portions 13a and 13b of the trunk edge receiving member 6 are inclined so as to enter the inside toward the bottom plate portion 12 side, so that the side plate portions 13a and 13b are inward against the force of spreading the side plate portions 13a and 13b. A strong restoring force is applied to pull back. For this reason, when the trunk edge 7 is fixed to the trunk edge receiving member 6 or when a weight is applied from the trunk edge 7, it is possible to suppress the trunk edge receiving member 6 from being greatly deformed.

  Then, by fixing the fixing plate portions 14 a and 14 b of the trunk edge receiving member 6 and the fixing plate portions 17 a and 17 b of the trunk edge 7 with screws, the trunk edge 7 is securely fixed to the trunk edge receiving member 6. can do. In addition, since the body edge 7 is formed so that the side plate portions 16a and 16b enter inside toward the top plate portion 15 side, the shoulder portion 19 even if the adapter 20 is brought into contact with the side plate portions 16a and 16b. It touches only at a point. As a result, since the interference of the side plate portions 16a and 16b with the rotation of the adapter 20 can be minimized, the screw 8 can be screwed in while the adapter 20 is brought close to or in contact with the side plate portions 16a and 16b. 16b can function appropriately as a guide for the adapter 20.

  Further, the guide groove 18 is formed in the fixed plate portions 17a and 17b, the tip of the screw 8 is fitted into the guide groove 18, and the adapter 20 is brought into contact with or close to the side plate portions 16a and 16b, whereby the screw 8 is fixed to the fixed plate portion 17a. , 17b. Thereby, since the guide function of the side plate portions 16a and 16b is effectively exhibited, it is possible to further reduce work mistakes such as screwing the screws 8 in an inclined state with respect to the fixed plate portions 17a and 17b.

  The body edge receiving member 6 and the body edge 7 constituting the base member 1 enter the inner side with the side plate portions 13a and 13b and the side plate portions 16a and 16b toward the bottom plate portion 12 side and the top plate portion 15 side. Therefore, the base member 1 as a whole can be prevented from being greatly deformed. Also, the top plate portion of the trunk edge 7 from the bottom plate portion 12 of the trunk edge receiving member 6 in which the bolt hole 11 is formed by the side plate portions 13a and 13b of the trunk edge receiving member 6 and the side plate portions 16a and 16b of the trunk edge 7. Since the space up to 15 can be sufficiently secured, the level adjustment width of the base member to be adjusted by the screwing amount of the bolt 5 into the bolt hole 11 can be increased.

  In addition, by causing the tip of the bolt 5 screwed into the bolt hole 11 to reach the trunk edge 7, the bolt 5 is inserted between the pair of side plate portions 13 a and 13 b in the trunk edge receiving member 6 and the trunk edge 7. The bolt 5 is inserted between the pair of side plate portions 16a and 16b. As a result, even if the trunk edge 7 and the trunk edge receiving member 6 are deformed due to a load or the like, the barrel edge 7 and the trunk edge receiving member 6 are received in order to receive the trunk edge 7 and the trunk edge receiving member 6 in which the bolt 5 is deformed. It is possible to prevent the member 6 from being greatly deformed, and to prevent the outer wall from proceeding to breakage.

  And by forming the trunk edge receiving member 6 and the trunk edge 7 in such a simple shape, the number of parts can be reduced and the forming process of the trunk edge receiving member 6 and the trunk edge 7 is facilitated. For this reason, it is possible to increase the wall thickness, to select a metal material having excellent weather resistance, and further to prevent contact corrosion by making the material of the trunk edge receiving member 6 and the trunk edge 7 the same metal. Can be prevented.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the fixing plate portions 14a and 14b of the trunk edge receiving member 6 and the fixing plate portions 17a and 17b of the trunk edge 7 are fixed using the screws 8. However, for example, fixing like a rivet is performed. You may carry out using a member.

  In the above embodiment, the guide groove 18 has been described as extending linearly in the longitudinal direction. However, the guide groove 18 may extend intermittently.

  Moreover, in the said embodiment, although both the trunk edge receiving member 6 and the trunk edge 7 shall be formed in cross-sectional trapezoid hat shape, it is good also as what forms only either one in cross-sectional trapezoid hat shape.
