Description

  The present invention relates to a snow stop fitting attached to a roof.

  Generally, a snow stopper is provided on the roof of a residential building in the heavy snow region.

  Such snow stoppers are installed at the time of new construction of a residential building. When installing after construction, either remove the roof tiles and install the snow stoppers, or cut the new hardware and cut the gaps between the roof tiles. And fixed with an adhesive or the like. Therefore, construction work is troublesome, and there is a concern that sufficient construction strength cannot be obtained when it is cut and attached.

Therefore, conventionally, as a snow stop fitting that can be attached to the existing roof, the lower end portion of the tile is sandwiched and fixed between the back lower plate connected from the snow stop plate and the back upper plate. A snow stopper has been proposed (see Patent Document 1).
JP 2003-20762 A

  However, in the case of the conventional snow stop fitting, as shown in FIG. 5, the snow stop plate a that blocks snow is composed of a rear lower plate b and a rear upper plate c connected to the snow stop plate a. Is sandwiched and fixed by the lower end portion e of the roof tile d, the fixed state becomes unstable if it is too far from the lower end portion e of the upper roof tile d.

  For this reason, it is conceivable that the back plate b is shortened to make the snow stop plate a as close as possible to the clamping and fixing position, that is, as close as possible to the lower end portion e of the roof tile d. a will be located. The snow stop plate a can exhibit the snow stop effect by the height H, but when the snow stop plate a is located immediately after the step of the roof tile d, the snow stop plate a is substantially from the height of the snow stop plate a. Only the height h minus the level difference is effective, and a sufficient snow stop effect cannot be obtained.

  Further, the conventional snow stopper is sandwiched and fixed to the lower end portion e of the roof tile d between the rear lower plate b and the rear upper plate c. There is concern that it will break.

  Further, since the roof tile d mainly supports the load at the lower end portion e and the upper end portion f, when the support portion g of the snow stop plate a is located at the center portion of the roof tile d, it is concentrated on the center portion. As a result, the load of the snow stop fitting is applied, and there is a concern that the roof tile d is likely to break.

  The present invention has been made in view of such circumstances, and a snow stop fitting that can be easily fixed to the roof of an existing residential building and that can exhibit excellent durability and a snow stop effect. It is intended to provide.

In order to solve the above-mentioned problems, a snow guard of the present invention is a snow guard that is attached to an existing roof, and has a width that can be inserted through a gap formed when the lower end of an existing roof tile is lifted. It is formed in the shape of a plate, and at its distal end, a locking portion bent in a U-shape that can be locked to the upper end of the roof tile is formed, and at the base end, opposite to the locking portion A locking piece formed with a fixing portion bent in a direction orthogonal to the longitudinal direction on the side, a snow stop plate fixed to the fixing portion of the locking piece, and extended from the snow stop plate, It consists of a support piece formed with a locking part bent in a U-shape that can be locked to the lower end of the roof tile, and the locking piece locks the locking part to the upper end of the roof tile. In a state where the snow stop plate is fixed to the portion, the snow stop plate is formed on the roof tile on which the locking portion is locked. The total length of the piece and the support piece has been made with a length that can be sandwiched and fixed the roof tile which is engaged with the locking portion from above and below.

  Further, in the above snow stopper fitting, the locking piece is set to a length that allows the snow stopper plate to be positioned on the covering tile of the roof tile.

As described above, according to the present invention , the locking piece of the snow stop fitting has the locking portion locked to the upper end portion of the roof tile and the locking portion is fixed to the fixing portion. Since the length of the snow stop plate can be placed on the roof tile that has been locked, the locking portion and the fixed portion are horizontally placed from the gap that is created when the lower end of the existing roof tile is lifted. After inserting the locking piece, the locking portion and the fixed portion are made vertical, and the inserted locking piece is pulled back to lock the locking portion to the upper end of the roof tile. By fixing to the snow stop plate, the snow stop plate can be placed on the roof tile and can be easily fixed to the roof of the existing residential building. In addition, since the total length of the locking piece and the supporting piece is such that the roof tile holding the locking portion can be clamped and fixed from above and below, It is attached by holding and fixing the roof tile between the locking piece locked to the part and the support piece locked to the lower end of the roof tile, so that a stable fixed state is obtained and the metal fitting is not detached. .

  In addition, by using a snow stop fitting with a locking piece that is set to a length that allows the snow stop plate to be positioned on the tile cover white, the load applied to the roof tile from the snow stop plate is the strongest covering. The load can be applied to the white portion, and excellent durability can be obtained. Further, the snow stop plate can be placed at a position sufficiently away from the step of the upper roof tile, and an excellent snow stop effect can be exhibited without being affected by the step.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an outline of the overall configuration of the snow stopper 1, and FIGS. 2 to 4 show a construction state of the snow stopper 1.

  That is, the snow stopper 1 includes a locking piece 2, a snow stopping plate 3, and a support piece 4, and can be attached to an existing roof 5.

  The roof tile 50 is fixed with a nail 53 or the like with its upper end engaged with a crosspiece 52 of the field board 51. And the roof 5 is formed by providing the roof tile 50 in order from the lower side to the upper side so that this fixed part may be covered with the lower end part of the other roof tile 50. In the present embodiment, the roof tile 50 is formed to have a size of about 350 mm in the flow direction and about 306 mm in the width direction, and the upper end portion of the roof tile 50 and the roof tile 50 covered by this upper end portion. The coating white 50a with the lower end is about 70 mm. Since the roof tile 50 is finished with its upper end fixed and the lower end free, the lower end of the roof tile 50 is lifted to the extent that a gap of about 20 mm or more can be formed. It is made to be able to.

The locking piece 2 is formed in a band plate shape having a width that can be inserted from the gap, that is, 20 mm or less, preferably 10 to 20 mm. A locking portion 21 bent in a U-shape that can be locked to the upper end portion of the roof tile 50 is formed at the distal end portion of the locking piece 2. A fixing portion 22 that is bent in a direction orthogonal to the longitudinal direction on the side opposite to the locking portion 21 is formed at the base end portion of the locking piece 2. Screw holes 20 are provided in the base end portion and the tip end portion of the fixing portion 22, respectively.

The snow stopper plate 3 has a lower end bent in a direction orthogonal to the snow stopper plate 3 to form a support portion 31 that supports the snow stopper plate 3. A recessed portion 32 is formed in the central portion of the support portion 31 so as to be recessed to ensure strength. The upper end portion of the snow stop plate 3 is bent to the opposite side to the support portion 31 for safety.

The support piece 4 is formed in the same band plate shape as that of the locking piece 2, and a locking portion 41 bent in a U-shape that can be locked to the lower end portion of the roof tile 50 is formed at the tip thereof. Is formed. A fixing portion 42 that is bent in a direction orthogonal to the longitudinal direction on the side opposite to the locking portion 41 is formed on the base end portion of the support piece 4. In the support piece 4, the fixing portion 42 is integrated with the center portion of the snow stop plate 3 by welding or caulking, and the support piece 4 extends from the position of the recessed portion 32 at the lower center of the snow stop plate 3 toward the support portion 31. It is made to extend along. The central base end portion of the snow stop plate 3 corresponding to the base end portion and the tip end portion of the fixing portion 42 of the support piece 4 in a state where the support pieces 4 are integrated so as to extend from the snow stop plate 3 in this way. And screw holes 30 are provided at the positions of the central upper end.

  The snow stopper 1 constructed as described above is in a state in which the screw hole 20 provided in the fixing portion 22 of the locking piece 2 and the screw hole 30 of the snow stopper plate 3 are matched with each other and fixed with screws 6. Thus, the length of the locking piece 2 and the support piece 4 is such that the roof tile 5 can be sandwiched and fixed between the locking portion 21 of the locking piece 2 and the locking portion 41 of the support piece 4 from above and below. Is set.

  Next, the construction procedure of the snow stopper 1 constructed as described above will be described.

  First, as shown in FIG. 2, in the existing roof 5, the lower end portion of the roof tile 50 provided at a position immediately above the roof tile 50 to which the snow stopper 1 is to be attached is lifted. Then, the locking piece 2 of the snow stopper 1 in which the locking portion 21 and the fixing portion 22 are horizontally laid is inserted from the lifted gap.

  As shown in FIG. 3, after the locking portion 21 of the locking piece 2 has been inserted to a position where it surely exceeds the upper end of the roof tile 50, the locking piece 2 is rotated so that the locking portion 21 is lowered. The fixed portion 22 is raised in the vertical direction.

  As shown in FIG. 4, the locking piece 2 is pulled back toward the lower end portion of the roof tile 50 in this state. Then, the locking portion 21 of the locking piece 2 is locked to the upper end portion of the roof tile 50, whereby the locking piece 2 is locked and fixed to the roof tile 50.

  And the latching | locking part 41 of the support piece 4 extended from the snow stop board 3 is made to latch to the lower end part of the roof tile 50, the screw hole 20 of the fixing | fixed part 22 of the latch piece 2, and the snow stop board 3 These fixing screw holes 30 are fixed with screws 6. As a result, in the snow stop fitting 1, the locking piece 2 and the support piece 4 sandwich and fix the roof tile 50, and the snow stop plate 3 is placed on the roof tile 50.

  In this state of completion of the construction, the locking piece 2 is only pulled back and locked after being inserted through the gap, so that at least the distance between the cover white 50a of the roof tile 50 and the locking portion 21 is pulled back. What is necessary is just to use the latching piece 2 which has the total length of these. Thereby, the snow stop plate 3 of the snow stop fitting 1 can be provided at any position from 100 mm to 350 mm from the upper end of the roof tile 50. Which position is provided can be determined by appropriately selecting the lengths of the locking piece 2 and the support piece 4.

  However, when the retaining piece 2 is shortened and the snow stop plate 3 is provided at a position close to the upper end portion of the roof tile 50, the snow stop plate 3 is close to the lower end portion of the upper roof tile 50. Thus, the snow stop effect by the snow stop plate 3 cannot be sufficiently exerted.

  Further, since the roof tile 50 supports the load at the upper end portion and the lower end portion, when the length of the locking piece 2 is set so that the snow stop plate 3 is located at the approximate center of the roof tile 50, The roof tile 50 is not preferable because the load from the snow stop plate 3 is most applied and is liable to break.

  Therefore, it is preferable to use the locking piece 2 whose length is set so that the snow stop plate 3 is located at a position on the lower end side further than the center of the roof tile 50. More preferably, the snow stop plate 3 is positioned within a range of about 70 mm in width, which is the covering white 50 a on the lower end side of the roof tile 50, that is, within a range of 280 mm to 350 mm from the upper end side of the roof tile 50. It is preferable to use one in which the length of the locking piece 2 is set.

  In any case, the length of the locking piece 2 is the total length of the locking piece 2 and the supporting piece 4 in accordance with the length of the locking piece 2. The length is determined so that the roof tile 50 can be sandwiched and fixed.

  According to the snow stopper 1, the locking piece 2 is inserted and locked through the gap between the existing roof tiles 50, and the locking piece 2 and the snow stop plate 3 are simply fixed with screws 6. Easy to install. Further, in this construction state, the snow retaining plate 3 retains the retaining portion 41 of the support piece 4 extending from the snow retaining plate 3 to the lower end portion of the roof tile 5 and sandwiches the roof tile 50 from above and below. Since it is fixed, a stable fixed state can be obtained.

  Further, by adjusting the length of the locking piece 2, the construction can be performed at a position close to the lower end of the roof tile 50 that is sufficiently separated from the upper roof tile 50. The stop plate 3 can be sufficiently used to obtain an excellent snow stop effect. Moreover, the snow stopper applied to the roof tile 50 is constructed by using the locking piece 2 whose length is adjusted so that the snow stopper plate 3 is positioned at the position of the covering white 50a near the lower end of the roof tile 50. Since the load of the metal fitting 1 can be borne on the portion of the strong covering white 50a, excellent durability can be obtained.

  In the present embodiment, the support piece 4 is formed integrally with the snow stop plate 3 and extends from the snow stop plate 3. However, the support piece 4 and the snow stop plate 3 are configured separately. It may be integrated when constructed on site.

  Moreover, in this Embodiment, the size of the roof tile 50 which comprises the roof 5 is not specifically limited, This Embodiment only showed the example.

  Further, in the present embodiment, the screw hole 20 of the fixing portion 22 of the locking piece 2 and the fixing screw hole 30 of the snow stop plate 3 are fixed by the screw 5, but the locking piece 2 is fixed. The bolt hole (not shown) of the portion 22 and the fixing bolt hole (not shown) of the snow stop plate 3 may be fixed with bolt nuts (not shown). In this case, the nut may be fixed to the bolt hole or the fixing bolt hole by welding in advance.

  It can be used as a snow stopper that can be attached to existing residential buildings.
