Description

  TECHNICAL FIELD The present invention relates to a corrugated sheet holder for retaining corrugated sheets used for snow removal on a slope such as a roof while being bent in a substantially U shape, and a corrugated sheet retaining structure using the corrugated sheet retainer. It is.

  Traditionally, in Japanese snowy countries, corrugated sheets made of synthetic resin (corrugated sheet material) bent into a substantially U-shaped groove shape or saddle shape are installed on sloping surfaces such as roofs and sloping ground, and formed by the corrugated sheets. A snow removal method is adopted in which a lump of snow is thrown into the groove by a snowplow such as a scoop, and the lump of snow is slid down and removed.

  As a tool used for such a snow removal method, for example, a wide snow-removing rod (Patent Document 1) in which a corrugated plate is attached to a cross-shaped frame having a high edge for preventing falling on one side, or a neutral shaft. A plurality of support frames formed symmetrically with respect to the left and right sides are attached to three connecting rods, the support frame has a support portion that is substantially semicircular or substantially L-shaped, A snow remover for a roof that is provided between support parts and is disposed along the support part, and is secured by using the restoring force of the corrugated sheet with both sides of the corrugated sheet in contact with the tip part (Patent Document 2) ) Etc. are known.

  In addition to this, as shown in FIG. 13, a hook 102 that holds the edge in the width direction of the corrugated plate 6 at both rising edges of the U-shaped frame 101 formed of metal or synthetic resin. There is also known a snow removal tool 100 provided with.

  In the snow removal tool 100 shown in FIG. 13, the corrugated plate 6 is brought into contact with the frame body 101, both end edges of the corrugated sheet 6 are inserted from the lower side of the hook 102, and the end edges of the corrugated sheet 6 are gripped. As a result, the corrugated plate 6 is held in a U-shape.

Registered Utility Model Publication No. 3117791 JP 09-203175 A

  The snow removal tool 100 shown in FIG. 13 as described above is simple in structure and can easily hold the corrugated sheet 6 in a U-shape, for example, an edge in the width direction of the corrugated sheet 6 by mistake (for example, a snow mass). The edge of the corrugated plate 6 in the width direction is shifted downward by the pressure (load) to come off from the hook 102 or the corrugated plate 6 contacts the frame body 101. There is a problem that the corrugated sheet 6 cannot be reliably held in a U-shape due to floating from the contact surface.

  In order to cope with this problem, means for increasing the clamping force by using another member such as a bolt instead of the hook 102 can be considered. However, when such means is used, the work of attaching and removing the corrugated sheet 6 is complicated. This may cause loss of other members such as bolts.

  The present invention has been made in view of the above problems, and the problem to be solved is that the corrugated sheet can be reliably held in a substantially U shape by simple work, and the edge in the width direction of the corrugated sheet A corrugated plate holder and a corrugated plate holding structure using the corrugated plate holder that does not cause the edge of the corrugated plate to slip down and the corrugated plate to rise from the contact surface of the frame even when pressure or load is applied to the plate. There is to do.

In order to achieve the above object, a corrugated sheet holder according to the present invention is a corrugated sheet retainer that bends a corrugated sheet and retains the corrugated sheet in a substantially U shape, and extends substantially horizontally and on both sides thereof. A substantially U-shaped frame composed of a raised portion, and a sandwiching portion provided on an upper portion of the raised portion of the frame for sandwiching the edge in the width direction of the corrugated plate, the corrugated plate contact surface of the frame A projecting part is provided on the side, and the sandwiching part has a substantially L-shape consisting of a projecting piece projecting inward from the upper part of the rising part and a hanging piece hanging downward from the projecting piece The corrugated plate contact surface of the frame in the sandwiching portion or the corrugated plate contact surface of the hanging piece of the sandwiching portion is provided with a stopper for restricting the intrusion of the corrugated plate. is there.

In the corrugated plate holder of the present invention, it is preferable that the convex portions are provided on the rising portion and the horizontal portion of the frame, respectively, and the convex portions have substantially the same shape as the peak portions of the corrugated plate. preferable. Further, the suspended piece of the upper Campanulaceae lifting unit, it is more preferable that the corrugated presser ridge for pressing the corrugated sheet inside is provided.

  Next, the corrugated plate holding structure of the present invention is a corrugated plate holding structure using any one of the above corrugated plate holders, and the corrugated plate holder is disposed on both end sides in the length direction of the corrugated plate, The corrugated plate is held such that the edge of the corrugated plate in the width direction is pinched by the holding portion of the holder and the peak portion of the corrugated plate is positioned on the convex portion provided on the frame.

The corrugated sheet holder according to the present invention is such that the corrugated sheet is brought into contact with a substantially U-shaped frame, and both end edges of the corrugated sheet are inserted from below the sandwiching section that sandwiches the edge in the width direction of the corrugated sheet. The corrugated plate can be held in a substantially U shape by a simple operation. At that time, the corrugated plate abutment surface of the frame is provided with a convex part, so that a snow mass is accidentally dropped on the edge in the width direction of the corrugated plate, and pressure or load is applied from above the corrugated plate. Even in such a case, since the convex part and the peak part of the corrugated sheet are fitted, the movement of the corrugated sheet in the width direction (left-right direction) is suppressed, and the problem that the corrugated sheet slips down or rises from the frame is solved. Thus, the corrugated plate can be held in a substantially U shape.
In addition, the peak part of a corrugated sheet said here means the corrugated sheet surface formed in the direction which rises away from the corrugated sheet contact surface side of a frame, and the trough part of a corrugated sheet means the above Conversely, it means a corrugated surface formed in a direction approaching the corrugated surface of the frame.

  Further, the corrugated plate holder in which the convex portions are provided on the rising portion and the horizontal portion of the frame respectively, the convex portion that suppresses the movement in the width direction (left and right direction) of the corrugated plate is provided on the rising portion and the horizontal portion of the frame. By providing them on both sides, it is possible to more reliably prevent the corrugated sheet from being displaced or lifted.

In particular, the corrugated plate holder in which the convex portion has substantially the same shape as the crest portion of the corrugated sheet has the strongest fitting force between the corrugated portion of the corrugated sheet and the convex portion, and the corrugated sheet does not slip down or rise. Will be equal.
The term “substantially the same shape as the crest of the corrugated plate” here refers to a shape that is similar to the crest of the corrugated plate and is slightly smaller than the crest of the corrugated plate.

Further, the sandwiching portion has a substantially L-shape including a projecting piece projecting inward from the upper part of the rising portion and a suspended piece hanging downward from the projecting piece, and a frame in the sandwiching unit. The corrugated sheet holder is provided with a stopper for restricting the corrugated sheet from entering the corrugated sheet contact surface or the corrugated sheet contact surface of the hanging piece of the sandwiching portion. Accordingly, the positional relationship between the convex portion that suppresses the movement of the corrugated plate and the peak portion of the corrugated sheet is made appropriate, and the convex portion and the peak portion of the corrugated sheet are reliably fitted.
That is, as is well known, the corrugated plate is formed by continuously forming a crest and a trough in the width direction, but one end in the width direction of the corrugated sheet is usually terminated at the top of the crest. And the other end terminates at the bottom of the trough. Therefore, the corrugated sheet has directionality in the width direction. If one end side that terminates at the top of the crest of the corrugated sheet is in contact with the upper end of one of the sandwiched parts, the corrugated sheet is corrugated. If the plate is bent while being in contact with the frame, the bottom end of the trough portion of the corrugated plate does not contact the top end of the other clamping portion, and the bottom end of the trough portion of the corrugated plate and the other end Between the upper ends of the sandwiching portions, a half pitch (the pitch here means the distance from the top of the mountain portion to the top of the adjacent mountain portion, and the half pitch is a valley adjacent to the top of the mountain portion. This means a distance to the bottom of the part.) In order to correct this gap, if the bottom end of the trough of the corrugated plate is also brought into contact with the top end of the other sandwiching portion, this time, a half pitch portion is formed between the peak of the corrugated plate and the convex portion of the frame. Since the shift occurs and the peak portion and the convex portion of the frame do not fit well, there is a possibility that the movement deterrence due to the convex portion is impaired. Therefore, the present invention provides a stopper for restricting the intrusion of the corrugated plate on the corrugated plate contact surface of the frame in the sandwiching portion or the corrugated plate contact surface of the hanging piece of the sandwiching portion. Or by restricting the bottom end of the valley part so that it cannot penetrate further into the clamping part, the positional relationship between the convex part and the peak part of the corrugated plate becomes appropriate, and the movement deterrence by the convex part is reduced. Securing and making workability very good.

  Furthermore, the corrugated plate holder in which the corrugated plate ridge that presses the corrugated plate to the inside is provided on the hanging piece of the sandwiching unit, the corrugated plate crests are in contact with the corrugated plate ridge. The crests of the plate are deformed inward, and by using the restoring force to return to the original shape at that time, both end edges of the corrugated plate can be clamped more firmly.

  Next, the corrugated sheet holding structure of the present invention using the corrugated sheet holder having the above-described configuration can be obtained by disposing the corrugated sheet holder having the above-described configuration on both ends in the longitudinal direction of the corrugated sheet. The corrugated plate can be reliably held in a substantially U shape. In addition, the holding structure having such an excellent function and effect makes the corrugated plate come into contact with the substantially U-shaped frame so that the corrugated plate is held from the lower side of the sandwiching portion that sandwiches the edge in the width direction of the corrugated plate. This can be realized by a simple operation of inserting both end edges. In addition, by making this holding structure continuous, it is possible to easily cope with a long inclined surface, which is extremely preferable.

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

  The corrugated sheet holder 10 of the present invention shown in FIG. 1 is a holder that holds the corrugated sheet 6 in a substantially U shape as shown in FIG. The corrugated plate 6 was developed so that it can be used for the snow removal work of the snow piled on the roof of the house.

  The corrugated plate holder 10 is preferably made of synthetic resin, rubber, metal or the like, and has a substantially U-shaped frame 1 and a substantially L-shape as shown in FIG. The clamping part 2 is provided.

  As shown in FIG. 1A, the frame 1 is composed of a substantially horizontal horizontal portion 1A and rising portions 1B and 1B extending upward in a circular arc shape from both sides (both ends) of the horizontal portion 1A. By arranging the corrugated sheet 6 along the corrugated plate contact surface (the inner surface side of the frame 1) of the frame 1, as shown in FIG. Shaped grooves are formed. Further, as shown in FIG. 1B, two screw holes 1a and 1a are formed in the horizontal portion 1A of the frame 1. As shown by the phantom line in FIG. 2, the screw hole 1a is formed by placing a rafter 7 below the corrugated plate holder 10 and punching a nail 8 or a screw through the screw hole 1a. When the corrugated plate holder 10 is installed on snow, the corrugated plate holder 10 is used when the stability of the corrugated plate holder 10 is not so good.

  Further, as shown in FIG. 1A, sandwiching portions 2 and 2 that sandwich the edge in the width direction of the corrugated plate 6 are provided at the upper ends of the rising portions 1 </ b> B and 1 </ b> B of the frame 1. As shown in FIGS. 4 and 5, the clamping portion 2 includes a protruding piece 2 a protruding from the upper end of the rising portion 1 B toward the inside of the corrugated plate holder 10, and downward from the protruding piece 2 a. The lower end of the hanging piece 2b on the insertion side of the corrugated plate 6 is formed in a divergent shape by rounding or chamfering, and the opening is widened. Since it is formed flexibly, the end edge of the corrugated plate 6 can be easily inserted into the clamping part 2.

The width W1 of the sandwiching portion 2, that is, the distance from the corrugated plate contact surface of the rising portion 1B to the hanging piece 2b is the height H1 of the corrugated plate 6 shown in FIG. 3 (from the bottom of the trough portion 6b of the corrugated plate 6). It is set to about 6 to 12 mm which is the same as or slightly smaller than the height of the peak 6a. In addition to this, the corrugated plate holder 10 of the present invention is provided with a corrugated plate pressing ridge 5 for pressing the corrugated plate inwardly on the hanging piece 2b of the pinching portion 2 in order to further increase the pinching force of the corrugated plate 6. It has been. As shown in FIGS. 4 and 5, the corrugated sheet pressing ridge 5 is formed in a vertical direction projecting outward from the inner surface (surface on the rising portion 1 </ b> B side) of the hanging piece 2 b of the sandwiching portion 2 in the outward direction (rising portion 1 </ b> B direction). And is formed substantially in the middle of the hanging piece 2b in the width direction. The projecting dimension T of this corrugated sheet pressing ridge 5 (the dimension projecting from the hanging piece 2b to the rising part 1B side) is set to about 0.5 to 6 mm, and the width W1 of the sandwiching part 2 is as described above. Since the height H1 of the corrugated plate 6 is set to about 6 to 12 mm and the edge of the corrugated plate 6 is inserted into the sandwiching portion 2, the peak portion 6a of the corrugated plate 6 is corrugated. It abuts on the plate presser protrusion 5 and deforms inward. At that time, since a restoring force is applied to the corrugated plate 6 to return to the original shape, both end edges of the corrugated plate 6 can be firmly held.
In addition, although the corrugated sheet pressing ridge 5 of the present embodiment is formed in a part of the clamping part 2 in the width direction, it may be formed over the entire width of the clamping part 2.

  As described above, since the corrugated sheet pressing protrusion 5 is provided on the hanging piece 2b of the sandwiching portion 2, the corrugating force of the corrugated sheet 6 is very high. There is no worry of slipping down and coming off from the clamping part 2, but even if a large snow block is accidentally dropped on the edge in the width direction of the corrugated plate 6, such a defect is surely ensured. In order to solve the problem, the corrugated sheet holder 10 of the present invention has a convex portion 3 that suppresses movement of the corrugated sheet 6 in the width direction (left-right direction) on the corrugated sheet contact surface side (inner surface side of the frame 1). Is provided.

  As shown in FIG. 6, the convex portion 3 has a shape in which, in the length direction of the frame 1, a curved shape is formed while forming a radius from a vertex that is raised in a curved shape while forming a radius. The plate 6 has substantially the same shape as the peak 6a. The shape substantially the same as the peak portion 6a of the corrugated plate 6 here is a concept that includes a shape that is similar and slightly smaller than the shape of the peak portion 6a of the corrugated plate 6, As shown in FIGS. 1A and 1B, a total of four convex portions 3 are provided over the entire width direction of the frame 1 at both ends of the rising portions 1 </ b> B and 1 </ b> B and the horizontal portion 1 </ b> A of the frame 1. It has been. When the convex portion 3 having such a shape is provided on the corrugated plate contact surface of the frame 1, when the corrugated plate 6 is held by the corrugated plate holder 10, the back surface of the peak portion 6 a of the corrugated plate 6 and the convex portion 3 are entirely exposed. Even if a large amount of pressure or load is applied from above the corrugated plate 6 by accidentally dropping the snow mass on the edge of the corrugated plate 6 in the width direction, There is no problem that the corrugated plate 6 slips down or floats up from the frame 1.

  The projection 3 is preferably provided over the entire width of the frame 1 as in the present embodiment, since the back surface of the crest 6a of the corrugated plate 6 and the projection 3 are in contact with each other, but the entire width of the frame 1 is not necessarily limited. For example, as shown in FIG. 12, two small protrusions 3 and 3 are provided on both sides in the width direction of the frame 1, and although not shown, the width direction of the frame 1 is not shown. Even if it is partially provided such as by providing one small convex portion 3 at the central portion, substantially the same effect is obtained.

Further, although the number of convex portions 3 provided on the frame 1 is the same as the number of peak portions 6a of the corrugated plate 6, there is an advantage that the fitting force is strongest. The work of holding the corrugated plate 6 on the plate holder 10 becomes complicated, and there is a negative aspect that the manufacturing cost increases. Most of the factors that cause the corrugated plate 6 to be detached from the sandwiching portion 2 are cases where the corrugated plate 6 is displaced due to a pressure or load applied in the vertical direction. It is effective to suppress the vertical movement of the plate 6. Therefore, it is more effective that the convex portion 3 that suppresses the movement of the corrugated plate 6 in the width direction (left-right direction) is provided on the rising portion 1B rather than the horizontal portion 1A. For example, as shown in FIG. Even if only one convex portion 3 is provided on the rising portion 1B, it is possible to prevent the corrugated plate 6 from slipping down. As shown in FIG. 11, if two convex portions 3 are provided on one rising portion 1B, the wave The problem that the plate 6 is detached from the clamping part 2 can be solved almost certainly. Thus, when providing the convex part 3 in the rising part 1B, it is preferable to provide it as much as possible, that is, as close to the edge of the corrugated plate 6 in the width direction, but it protrudes to a position where it interferes with the sandwiching part 2. When the portion 3 is present, it is difficult to insert the edge of the corrugated plate 6 into the sandwiching portion 2, and therefore it is preferable to provide the convex portion 3 with an appropriate interval from the sandwiching portion 2.
In addition, if the convex part 3 is provided in the corrugated sheet contact surface of the frame 1 located in the sandwiching part 2 or the inner surface of the hanging piece 2 b of the sandwiching part 2, the edge of the corrugated sheet 6 is inserted into the sandwiching part 2. However, providing the convex portion 3 at such a position also has an advantage that the movement of the corrugated plate 6 can be surely suppressed.

  On the other hand, the convex portion 3 provided in the horizontal portion 1A suppresses the horizontal movement of the corrugated plate 6, but during snow removal work, pressure and load from the horizontal direction are applied to the corrugated plate 6. It is not often loaded, and it does not make much sense to provide the convex portion 3 in the center of the horizontal portion 1A. Therefore, when the convex portion 3 is provided on the horizontal portion 1A, it is provided on the outermost side of the horizontal portion 1A, that is, in the vicinity of the boundary between the rising portion 1B and the pressure from above applied to the edge of the corrugated plate 6 or The corrugated plate holder 10 of the present embodiment is preferable because it can efficiently receive the load. As described above, the corrugated plate holder 10 of the present embodiment is combined with the rising portions 1B and 1B of the frame 1 as described above. A total of four convex portions 3 are provided at both ends of the horizontal portion 1A.

  Needless to say, the height H2 and the width W2 of the convex portion 3 are changed depending on the size of the corrugated plate 6 to be held. However, many of the corrugated plates 6 that are usually marketed have a height H1 (valley portion 6b). The height from the bottom of the ridge 6a to the top of the ridge 6a is about 6 to 12mm, and the pitch P (distance from the ridge 6a to the top of the adjacent ridge 6a) is about 30 to 34mm, Accordingly, the height H2 of the convex portion 3 is often formed to be about 5 to 11 mm and the width W2 is about 18 to 30 mm.

Next, as shown in FIG. 3, the corrugated plate 6 held by the corrugated plate holder 10 is formed by continuously forming ridges 6a and valleys 6b in the width direction. A corrugated sheet 6 made of a polycarbonate resin, which is excellent in impact resistance, weather resistance, and cold resistance, is preferably used. This corrugated plate 6 has various sizes, but considering the use, workability, and transportability, the length is about 1800 to 1850 mm, the width is about 640 to 1100 mm, and the height H1 (the valley portion 6b). A corrugated plate 6 having a height from the bottom of the ridge 6a to the top of the peak 6a of about 6 to 12 mm and a pitch P (distance from the top of the ridge 6a to the bottom of the valley 6b) of about 30 to 34 mm is preferable. Used.
Here, the peak portion 6a of the corrugated plate 6 means a corrugated surface formed in a direction that rises away from the corrugated plate contact surface side of the frame 1, and the trough portion 6b of the corrugated plate 6 Means a corrugated plate surface formed in a direction approaching the corrugated plate abutting surface of the frame 1 contrary to the above-described peak portion 6a.

  As described above, the corrugated plate 6 is formed by continuously forming the crest 6a and the trough 6b in a corrugated shape, but the corrugated plate 6 that is usually marketed is shown in FIG. If one end (here, the left end) ends at the top of the peak portion 6a, the other end (here, the right end) ends at the bottom of the valley portion 6b. Thus, since the corrugated sheet 6 is asymmetrical in the width direction and has directionality, it is assumed that one end side that terminates at the bottom of the trough part 6 b of the corrugated sheet 6 is contacted with the upper end of one sandwiching part 2. When the corrugated plate 6 is bent in contact with the corrugated plate contact surface of the frame 1 in the contacted state, the end of the top of the peak portion 6a on the other end side is the other end as shown in FIG. A gap S corresponding to ½ pitch P is generated between the end of the top of the peak portion 6 a and the upper end of the sandwiching portion 2 without contacting the upper end of the sandwiching portion 2. In the state where the gap S is generated, the retainability of the corrugated sheet 6 may be impaired, and the corrugated sheet 6 may be lifted from the frame 1, and the top of the peak portion 6a on the other end side is filled to fill the gap S. Is brought into contact with the upper end of the other sandwiching portion 2, this time, a deviation of ½ pitch P occurs between the peak portion 6 a of the corrugated plate 6 and the convex portion 3 of the frame 1. The part 3 and the peak part 6a do not fit well, and there is a possibility that the movement deterrence by the convex part 3 is impaired. In order to solve such a problem, the corrugated plate holder 10 of the present invention is provided with a stopper 4 described below.

  That is, the stopper 4 that makes the positional relationship between the convex portion 3 and the peak portion 6a appropriate and ensures the movement deterring property of the corrugated plate 6 by the convex portion 3 is as shown in FIGS. It is provided on the left and right rising portions 1B and 1B, respectively. As shown in FIG. 7, the stopper 4 is a protrusion provided to restrict the edge (terminal) of the corrugated plate 6 from entering the inner part of the sandwiching portion 2 any more. As shown in FIG. 2, the upper end of the corrugated plate contact surface (inner surface) on the hanging piece 2b side in the holding part 2 is provided so as to be symmetrical. As described above, the corrugated plate 6 is asymmetrical, and when bent while being in contact with the corrugated plate contact surface of the frame 1, between the one end of the corrugated plate 6 and the upper end of the sandwiching portion 2, Since the gap S corresponding to ½ pitch P is generated, the stopper 4 corrects the gap S. Therefore, as shown in FIG. 4, the stopper 4 moves downward by the dimension of the gap S (that is, ½ pitch P). It is provided to protrude.

If the stopper 4 is provided in either the right or left sandwiching portion 2, the positional relationship between the convex portion 3 and the peak portion 6a can be made appropriate, but the corrugated plate 6 is If the left end terminates at the top of the peak 6a, the right end terminates at the bottom of the valley 6b. Even if the corrugated plate 6 is turned upside down, the left end terminates at the top of the peak 6a. The right end is terminated at the bottom of the valley 6b. If the left end of the corrugated plate 6 is terminated at the top of the peak portion 6a as in the present embodiment, if the stopper 4 is provided only on the left sandwiching portion 2, the gap S is corrected and the convex portion 3 and the peak portion 6a have an appropriate positional relationship, but some of the commercially available corrugated plates 6 have the left end terminated at the bottom of the valley portion 6b. In this way, in the case of the corrugated plate 6 whose left end is terminated at the bottom of the trough 6b, even if the stopper 4 is provided only on the hanging piece 2b side of the left sandwiching portion 2, the edge of the corrugated plate 6 contacts the stopper 4 Therefore, the meaning of providing the stopper 4 is lost. Accordingly, the stopper 4 of the present embodiment is provided symmetrically on the side of the hanging piece 2b of the holding part 2 on both the left and right sides, whereby the left end of the corrugated plate 6 terminates at the top of the peak part 6a. Even in the case where it terminates at the bottom of the valley 6b, the positional relationship between the convex 3 and the peak 6a becomes appropriate, and the convex 3 and the peak 6a are securely fitted, The movement of the corrugated plate 6 is suppressed.
The stopper 4 can be provided on the hanging piece 2b side of the clamping part 2 as in the present embodiment, or can be provided on the corrugated surface at the upper end of the rising part 1B in the clamping part 2. Needless to say, if the stopper 4 extending from the corrugated contact surface at the upper end of the rising portion 1B in the holding portion 2 to the hanging piece 2b is provided, the stopper 4 is provided on either the left or right holding portion 2. Has the same effect as above.

  Next, the corrugated sheet holding structure of the present invention using the corrugated sheet holder 10 having the above-described configuration will be described.

  In the corrugated plate holding structure of the present invention, as shown in FIG. 9, the corrugated plate holders 10 are arranged at both ends in the length direction of the corrugated plate 6 and at substantially the center in the length direction of the corrugated plate 6. Then, the edge of the corrugated plate 6 is inserted into the sandwiching portions 2 and 2 of the corrugated plate holder 10 so as to sandwich the end of the corrugated plate 6, and the convex portion provided on the frame 1. 3 and the corrugated portion 6a of the corrugated plate 6 are fitted together to hold the corrugated plate 6 in a substantially U shape.

  In the present embodiment, as described above, the corrugated sheet 6 is held by using the three corrugated sheet holders 10. However, if at least both sides of the corrugated sheet 6 are held by the corrugated sheet holder 10, the corrugated sheet 6 is retained. If the corrugated plate 6 can be held in a substantially U-shape, and the corrugated plate 6 is very long, the number of corrugated plate holders 10 may be increased as appropriate.

  As described above, the corrugated sheet holder 10 that retains the corrugated sheet 6 is installed on an inclined surface such as a roof or sloping ground with snow, and a scoop or the like is formed in a groove formed in a substantially U shape by the corrugated sheet 6. The snow removal work is done by throwing a lump of snow with a snow removal tool and sliding the lump to the bottom. When the corrugated plate holder 10 is installed on an inclined surface on the snow, and the stability of the corrugated plate holder 10 is not good, a rafter 7 is placed below the corrugated plate holder 10 as shown in FIG. By arranging and driving a nail 8 or a screw through the screw hole 1a, stability can be ensured.

  When the snow removal work is on the roof, the corrugated plate 6 can be used for most cases. However, when the work place is a long sloping ground, a plurality of corrugated sheets 6 are used. A plurality of holders 10 may be used. As shown by the arrow in FIG. 9, the corrugated plate 6 and the corrugated plate 6 are connected to each other in the lengthwise direction of the corrugated plate 6 positioned on the lower side. This can be done easily by overlapping the edge from above. By performing this according to the length of the slope, it is possible to cope with a long slope.

  On the other hand, when it is necessary to remove the corrugated sheet 6 from the corrugated sheet holder 10 with the arrival of spring, and to remove the corrugated sheet 6 from the corrugated sheet holder 10, the corrugated sheet 6 is first pushed upward from the back surface side, If the end of the corrugated plate 6 is pulled out from the holding part 2 and then the corrugated plate 6 is pulled out, the corrugated plate 6 can be easily removed from the corrugated plate holder 10, and the corrugated plate 6 can be removed. Can be used for

  As is clear from the above description, the corrugated sheet holder 10 of the present invention and the corrugated sheet holding structure using the corrugated sheet holder 10 are configured such that the corrugated sheet 6 is brought into contact with the substantially U-shaped frame 1. The corrugated sheet 6 can be reliably held in a substantially U shape by a simple operation of inserting the edge of the corrugated sheet 6 from below the clamping part 2. At that time, since the stopper 4 is provided on the hanging piece 2b side of the sandwiching part 2, the convex part 3 and the peak part 6a of the corrugated sheet 6 are securely fitted, and even if the pressure is applied to the edge in the width direction of the corrugated sheet 6 Even when a load is applied, the edge of the corrugated sheet 6 does not slip down or the corrugated sheet 6 is lifted from the contact surface of the frame 1, and the corrugated sheet 6 remains substantially U-shaped for a long time. Can be held. Moreover, by continuously constructing the corrugated plate holding structure using the corrugated plate holder 10 that exhibits such excellent effects, it is possible to easily cope with a long inclined surface for performing snow removal work. Is very preferable.
