Description

  The present invention relates to an exterior plate fixture for fixing an exterior plate such as a corrugated plate, and more particularly to an exterior plate fixture capable of attaching another member such as a roof structure on the exterior plate.

  For fixing the corrugated plate, a fixture as disclosed in Patent Document 1 below is used. This fixture consists of a drill screw and a washer. The drill screw has a drill portion, a pair of reamers, a screw portion, and an annular stopper in this order from the tip, and has a hexagon head at the upper end. The washer has a washer body shaped like a corrugated plate, and a seal packing is accommodated under the washer body.

  In this fixture, the drill screw is pressed onto the corrugated plate and rotated while holding the washer and seal packing on the drill screw, and after passing through the corrugated plate, is screwed into the structural material below the corrugated plate. At this time, the annular stopper comes into contact with the structural material, and the washer and the seal packing hold the corrugated plate.

  However, since the distance between the annular stopper and the hexagonal head is constant, the appropriate length depends on the difference in the corrugated plate size, the presence or absence of a backing material, the presence or absence of a ceiling plate under the corrugated plate, etc. A drill screw must be prepared. If there are variations in the thickness and height of the corrugated sheet, it cannot be dealt with.

  As a metal fitting for fixing the roof plate and attaching the structure on the roof, there is a metal fitting disclosed in Patent Document 2 below. This metal fitting has a screw rod-like attachment portion for attaching a rooftop structure above a support shaft portion having a bolt head-like rotational force input portion, and a fixing portion having a drill screw portion below the support shaft portion. It has. The fixing of the roof plate and the attachment of the structure on the roof can be performed easily and firmly. However, also in this metal fitting, the distance between the contact portion at the lower end of the support shaft portion corresponding to the annular stopper and the rotational force input portion corresponding to the hexagonal head is constant.

  In view of this, the main object of the present invention is to make it possible to flexibly cope with a difference or variation in the dimensions of an exterior plate or the like so that it can be firmly fixed.

  The means for this is provided with an outer plate, a drill screw portion that cuts into the base material supporting the outer plate in order from the top, and a fixing screw portion that is screwed into the base material at the tip portion, and a separate member is attached to the upper end portion. The mounting plate fixing device includes an abutting portion that protrudes outward from the fixing screw portion and contacts the base material from above at a position adjacent to the upper side of the fixing screw portion. A screw portion into which a nut that presses down the exterior plate from above is screwed is provided above, the mounting portion is provided on the screw portion, and a rotation input portion having a smaller diameter than the mounting portion is provided on the mounting portion. And the screw part is formed longer than the height of the nut, the attachment part is formed in a rod shape having the same diameter as the screw part, and a series of external screws are formed on the screw part and the attachment part. It is a board fixture

  In this configuration, when the rotary input part above the attachment part is rotated and the drill screw part is sequentially cut into the exterior plate and the base material, and the fixing screw part is screwed into the base material, the exterior plate fixture penetrates the exterior plate. It will be in a state of being stabbed into the base material. At this time, the abutting portion on the fixing screw portion abuts on the upper surface of the base material to improve stability. A nut for pressing the exterior plate from above is screwed into a portion of the threaded portion of the exterior plate fixture in this state protruding above the exterior plate. Since the threaded portion is longer than the height of the nut, a difference or variation in height below the surface of the exterior plate is allowed. Thereafter, another member is attached to the attachment portion of the exterior plate fixture on the fixed exterior plate as necessary. Since the attachment portion has a rod shape with the same diameter as the screw portion, and the rotation input portion has a smaller diameter than the attachment portion, insertion of another member into the attachment portion is allowed.

  According to the present invention, it is possible to firmly fix an exterior plate or another member flexibly corresponding to a difference or variation in dimensions.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of an exterior plate fixing tool 11. The exterior plate fixing tool 11 includes a base plate made of C-type steel or the like as a corrugated sheet 12 as an example of an exterior plate as shown in FIGS. In addition to being fixed on the material 13, a separate member 14 attached on the corrugated sheet 12, for example, a structure on the roof such as a solar panel, is attached to a portion protruding above the corrugated sheet 12. In addition to such a roof structure, it can also be used to form an outer wall. In order to fix the corrugated sheet 12, as shown in FIG. 4, a nut 15, a washer 16, and a packing 17 that press the corrugated sheet 12 from the top are attached to the exterior plate fixture 11.

  The exterior plate fixture 11 includes a corrugated plate 12 and a drill screw portion 21 that cuts into the base material 13 that supports the corrugated plate 12 in order from the top, and a fixing screw portion 22 that is screwed into the base material 13 at the top end portion. Is provided with a mounting portion 23 for mounting the above-described separate member 14.

  The drill screw portion 21 has a known configuration, and a fixing screw portion 22 is continuously formed on the drill screw portion 21. At a position adjacent to the upper side of the fixing screw portion 22, a contact portion 24 that protrudes outward from the fixing screw portion 22 and comes into contact with the base material 13 from above and a punching blade 25 that cuts into the corrugated plate 12 are provided. A screw portion 26 into which the above-described nut 15 is screwed is provided above, the above-described mounting portion 23 is provided on the screw portion 26, and rotation for rotating the exterior plate fixture 11 on the mounting portion 23. An input unit 27 is provided.

  The fixing screw portion 22 is appropriately formed so as to be firmly fixed to the base material 13, and the screw portion 26 is formed longer than the height of the nut 15. The length of the screw portion 26 can be set as appropriate, but it is preferable to set the length longer so as to absorb the difference in size and variation of the corrugated sheet 12.

  The attachment portion 23 has a rod shape having the same diameter as that of the screw portion 26, and a series of male screws are formed on the screw portion 26 and the attachment portion 23. For this reason, there is no clear division between the attachment portion 23 and the screw portion 26 in appearance, and the division is fluid. Actually, the portion above the nut 15 when the corrugated plate 12 is fixed by screwing the nut 15 becomes the attachment portion 23. The length of the attachment portion 23 is appropriately set according to the separate member 14 to be attached.

  A constricted portion 28 that is constricted in a circular arc shape when viewed from the front is formed between the attachment portion 23 and the rotation input portion 27. The rotation input unit 27 is formed in an appropriate shape for coupling with a rotation jig (not shown) and has a smaller diameter than the attachment unit 23. The rotation input unit 27 in the illustrated example has a hexagonal column shape.

  The contact portion 24 and the punching blade 25 are formed at the lower end of the large diameter portion 29 having a larger diameter than the fixing screw portion 22. Although the exterior plate fixture 11 having the large diameter portion 29 can be formed by shaving, in this example, the large diameter portion 29 is formed by winding a metal plate. That is, the exterior plate fixture 11 is formed of a bar-shaped member 11a and a plate member 11b made of a metal plate as shown in FIG.

  The rod-shaped member 11a includes a drill screw portion 21, a fixing screw portion 22, a screw portion 26, a mounting portion 23, and a rotation input portion 27 in order from the bottom. The plate member 11b is wound between the fixing screw portion 22 and the screw portion 26 of the rod-like member 11a.

The portion of the bar-shaped member 11a around which the plate member 11b is wound, that is, the plate member winding portion 30, also functions to set the distance to the screw portion 26 and is fixed.
Depending on the size, the length is set to an appropriate length so that the corrugated sheet 12 can be pressed by the nut 15 screwed into the threaded portion 26.

  A receiving portion 31 that receives the upper end of the plate member 11 b is formed integrally with the upper end portion of the plate member winding portion 30. The receiving portion 31 is provided on the lower surface of the annular portion 32 that protrudes like a bowl. The annular portion 32 is formed by providing small diameter portions 33 and 34 having a smaller diameter on the upper and lower sides.

  The portion below the small diameter portion 34 below the annular portion 32 of the plate member winding portion 30 has irregularities 30a for improving the fixability of the wound plate member 11b. In the example of illustration, the unevenness | corrugation 30a is formed with the external thread of the fixing screw part 22, and a series of external threads. In addition to the male screw, for example, a large number of quadrangular pyramids or conical protrusions may be used.

  The plate member 11b is substantially rectangular, and has a vertical length corresponding to a desired distance from the lower end contact portion 24 to the screw portion 26 as described above, and a predetermined horizontal length wound around the rod-like member 11a only once. Is set. The thickness of the plate member 11b is a thickness corresponding to the diameter of the large-diameter portion 29 that protrudes from the fixing screw portion 22 to the outer periphery.

  A plurality of convex portions 35 and concave portions 36 are formed at the lower end of the plate member 11b. The tip of the convex portion 35 is the abutting portion 24 described above, and the convex portion 35 and the concave portion 36 constitute the aforementioned perforating blade 25. For this reason, the tip of the convex portion 35 is slightly inclined.

  Both sides of the plate member 11b, that is, portions that come into contact with each other when wound, have a fitting convex portion 37 and a fitting concave portion 38 that are fitted to each other. These are horizontal T-shaped and fulfill the function of maintaining the winding state.

  When the plate member 11 b is wound around the plate member winding portion 30, the entire upper end portion of the plate member 11 b hits the receiving portion 31 along the small diameter portion 34 below the annular portion 32 and forms a straight upper end edge 39. For this reason, it has the reduced diameter part 29a which becomes a little thin in the upper part of the outer peripheral surface of the board member 11b.

  The attached packing 17 is formed in a thick disk shape as shown in FIG. 4, has elasticity, and has a through hole 17a in the center. The diameter of the through hole 17a is a size corresponding to the fitting portion described above.

  When the roof structure is configured using the exterior plate fixture 11 having the above configuration, the following is performed.

  First, as shown in FIG. 6, the corrugated sheet 12 is placed on the base material 13, and the drill screw part 21 at the tip is pressed to the position where the corrugated sheet 12 is fixed, and the rotating input part 27 is rotated. The outer plate fixing tool 11 is rotated by fitting a jig. Then, as shown in FIG. 7, in the exterior plate fixture 11, the drill screw portion 21 and the drilling blade 25 cut into the corrugated plate 12 and penetrate the corrugated plate 12. When the corrugated plate 12 is drilled, the upper end portion of the large-diameter portion 29 of the exterior plate fixture 11 has a reduced diameter portion 29a and a small-diameter portion 33 above it, so that cutting waste is smoothly removed. The

  The drill screw portion 21 is subsequently cut into the base material 13, and the fixing screw portion 22 is screwed into the base material 13. As shown in FIG. 8, the fixing screw portion 22 is screwed to the base material 13 until the contact portion 24 contacts the base material 13, and when the screwing is completed, the exterior plate fixture 11 is connected to the fixing screw portion 22. The contact portion 24 is firmly and stably fixed by the cooperation.

  Thereafter, the packing 17 and the washer 16 are inserted into the screw portion 16, and then the nut 15 is screwed into the screw portion 26. Although the rotation input part 27 is formed in the upper end of the exterior board fixing tool 11, since the rotation input part 27 is smaller diameter than the attachment part 23 of the same diameter as the screw part 26, attachment of packing 17 etc. can be performed easily. .

  By tightening the nut 15, the packing 17 is compressed via the washer 16, the hole 12 a in the corrugated sheet 12 is closed, and the corrugated sheet 12 is pressed. As a result, a roof is formed as shown in FIG.

  Next, another member 14 is attached as shown in FIG. The attachment of the separate member 14 is performed on a portion above the nut 15 including the attachment portion 23 in the exterior plate fixture 11 of the portion that needs to be attached. That is, the through hole 14a formed in the separate member 14 is inserted into a portion above the nut 15 and the nut 40 is screwed. In this way, a roof to which the structure on the roof is attached is formed.

  As described above, the exterior plate fixture 11 is firmly fixed with good stability by the cooperation of the fixing screw portion 22 and the abutting portion 24. Therefore, the corrugated plate 12 is firmly fixed. Further, the fixing work is simple because the outer plate fixing tool 11 is pressed and rotated. In addition, the water can be stopped well by one packing 17 and the elasticity of the packing 17 contributes to the firm fixing without the deviation of the corrugated sheet 12 in addition to the water stopping.

  Since the screw portion 26 into which the nut 15 is screwed is longer than the height of the nut 15, the corrugated plate 12 can be fixed at an appropriate position. That is, the distance between the contact portion 24 and the nut 15 can be fixed even if the distance is not constant. For this reason, even if there is a difference or variation in the height of the corrugated sheet 12, and even when the overlapping portion of the corrugated sheet 12 is fixed, the desired strong fixing can be reliably performed.

  As shown in FIG. 11, even when the corrugated sheet 12 has the backing material 12b on the back surface, the exterior plate fixture 11 of the same size absorbs the difference in height due to the backing material 12b, and the desired fixed state is obtained. can get.

  When the height of the fixing position of the corrugated sheet 12 is extremely higher than the presence or absence of the backing material 12b, for example, when the ceiling board 18 is disposed on the base material 13 as shown in FIG. The exterior plate fixture 11 having a long threaded portion 26 is used. The length of the large-diameter portion 29 or the plate member winding portion 30 may be increased instead of the exterior plate fixture 11 having a long screw portion 26, but as described above, the length of the screw portion 26 is increased. Easy to manufacture.

  Although the rotation input part 27 for rotation is provided in the upper end of the exterior board fixing tool 11, since it is formed in the diameter smaller than the attachment part 23, attachment of the separate member 14 is easy and the magnitude | size of the through-hole 14a is provided. Since it can be made small, it can be firmly fixed.

  Since the exterior plate fixture 11 is formed by a combination of the rod-shaped member 11a and the plate member 11b, it can be easily processed and manufactured at low cost. In addition, the receiving portion 31 is formed on the rod-like member 11a, and the receiving portion 31 receives the upper end edge 39 of the plate member 11b to prevent upward displacement, so that the strength is high.

In correspondence between the configuration of the present invention and the configuration of the above-described embodiment,
Although the exterior board of this invention corresponds to the above-mentioned corrugated board,
The present invention is not limited to the above-described configuration, and other configurations can be adopted.

  For example, the exterior plate may be another plate material such as a folded plate, or a siding for a wall. As the separate member, a necessary member is appropriately selected according to the use of the exterior plate.

  The receiving part for receiving the plate member for forming the large diameter part may be formed by extending to the outer periphery without providing the upper and lower small diameter parts, or the upper small diameter part may be omitted.
