Description

Technical Field

[0001] The present invention relates to a trimming member disposed at an overlapping portion of roofing materials when painting the roofing materials.

Background Art

[0002] Edge trimming refers to the operation of cutting by hand the blocked portion to create a gap in order to prevent the overlapping portion of the roofing material from being blocked by the coating film after painting the roofing material. If there is no gap in the overlapping portion of the roofing material, rainwater and the like cannot be discharged from inside the roofing material, the base material and the like are damaged, and it is necessary to perform edge trimming work because it causes rain leakage. However, it has been time-consuming to cut the coating film by hand to create a gap.

[0003] Therefore, a method is known in which a trimming member is disposed in advance at the overlapping portion of the roofing materials before painting to prevent the overlapping portion of the roofing materials from being blocked by the coating film. For example, it is known to insert the "trimming member for roofing materials" which is the invention of Patent Document 1 into the overlapping portion before painting.

[0004] The invention of Patent Document 1 is used by being inserted into the overlapping portion of the roofing materials. If it is inserted before painting, it is possible to prevent the overlapping portion of the roofing materials from being blocked by the coating film. Further, since the trimming member for roofing materials of Patent Document 1 is deformed when stepped on, the roofing material has a structure in which it is difficult to be damaged even when a load is applied, such as when a person steps on the outer peripheral portion where the trimming portion of the roofing material is inserted.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the edge-cutting member of the roofing material in Patent Document 1 could not sufficiently secure the size of the drainage outlet for discharging rainwater or the like, and there was a problem that rainwater or the like accumulated around the edge-cutting member of the roofing material.

[0007] Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to ensure a gap that can more reliably discharge rainwater or the like, and to be easily deformed and difficult to break when a load is applied by a person stepping on it or the like. In addition, since there are various differences in the body weight of the person stepping on and the size of the shoes, it can be said that the thinner the thickness of the member to be inserted, the less likely the roofing material is to crack.

Means for Solving the Problems

[0008] To achieve the above object, the present invention comprises at least the following configuration or executes the following procedure. In the following description, reference numerals and the like shown in the drawings may be added to facilitate the understanding of the present invention, but each component of the present invention is not limited to those shown in the drawings and should be widely interpreted to the extent technically understandable by those skilled in the art.

[0009] The edge-cutting member according to one aspect of the present invention is an edge-cutting member disposed at an overlapping portion of an upper roofing material and a lower roofing material, and includes a main body portion inserted into the overlapping portion of the upper roofing material and the lower roofing material, and a stopper portion that catches on the lower end portion of the upper roofing material and serves as positioning during insertion. The main body portion includes a central plate, inclined plates provided so as to extend obliquely downward from both lateral ends of the central plate, support plates provided so as to extend from the lateral ends of the inclined plates, a fin member provided near the center of the central plate, and a support portion that contacts and supports the lower roofing material when pressure is applied to the edge-cutting member and it deforms. The stopper portion is provided at the rear end of the central plate. One end of the fin member is connected to the central plate, and the other end protrudes obliquely downward in a direction opposite to the insertion direction of the main body portion. The support portion is provided near the center between the central plate and the stopper portion and protrudes below the central plate. With such a configuration, it is possible to more reliably secure a gap for discharging rainwater and the like, and to provide an edge-cutting member that is easily deformed and difficult to break when a load is applied, such as when a person steps on it.

[0010] Also, preferably, one end of the fin member connected to the central plate is formed to be narrower in width than the other end of the fin member. With such a configuration, it is possible to increase the contact area between the fin member and the roofing material while suppressing the repulsive force of the fin member. In other words, it is possible to provide an edge-cutting member in which the gap at the overlapping portion of the roofing material is difficult to widen and difficult to come off.

[0011] Also, preferably, it is formed of a stainless steel material. With such a configuration, an organic solvent can be used during roof painting, and the strength can also be improved.

[0012] Also, preferably, when pressure is applied to the edge-cutting member and it deforms, and the support portion contacts the lower roofing material, the tip of the support plate contacts the back surface of the upper roofing material. With such a configuration, when pressure is applied and it deforms, it can also be supported by the support plate, so the durability of the edge cutting member can be improved.

[0013] Furthermore, the edge cutting member according to one aspect of the present invention is an edge cutting member disposed at an overlapping portion of an upper roof material and a lower roof material, and includes a main body portion inserted into the overlapping portion of the upper roof material and the lower roof material, and a stopper portion that catches on the lower end portion of the upper roof material and serves as positioning during insertion. The main body portion includes a central plate, inclined plates provided so as to extend obliquely downward from both lateral ends of the central plate, support plates provided so as to extend from the lateral ends of the inclined plates, and a fin member provided near the center of the central plate. The stopper portion is provided at the rear end of the central plate, and one end of the fin member is connected to the central plate, and the other end protrudes obliquely downward in a direction opposite to the insertion direction of the main body portion. When pressure is applied to the edge cutting member and it deforms, the tip of the support plate contacts and supports the back surface of the upper roof material. With such a configuration, it is possible to ensure a gap for more reliably discharging rainwater and the like, and to provide an edge cutting member that is easily deformed and difficult to break when a load is applied, such as when a person steps on it.

Effects of the Invention

[0014] As described above, according to the present invention, it is possible to ensure a gap for more reliably discharging rainwater and the like, and to provide an edge cutting member that is easily deformed and difficult to break when a load is applied, such as when a person steps on it.

Mode for carrying out the invention

[0016] Hereinafter, each embodiment of the present invention will be specifically described with reference to the drawings. The embodiments described below are merely specific examples for carrying out the present invention, and do not limitatively interpret the present invention.

[0017] FIG. 1 is a view showing an edge-cutting member 100 according to the first embodiment of the present invention, and is a view showing (a) a plan view, (b) a side view, and (c) a rear view. FIG. 2 is a view showing a situation where the edge-cutting member 100 according to the first embodiment of the present invention is disposed at an overlapping portion between an upper roof member 10 and a lower roof member 20. The edge-cutting member 100 is disposed at an overlapping portion between the upper roof member 10 and the lower roof member 20, and includes a main body portion 110 inserted into the overlapping portion between the upper roof member 10 and the lower roof member 20, and a stopper portion 120 that engages with a lower end portion of the upper roof member 10 and serves as a positioning means during insertion. Further, the main body portion 110 includes a central plate 130, inclined plates 140 provided so as to extend obliquely downward from both lateral ends of the central plate 130, support plates 150 provided so as to extend from lateral ends of the inclined plates 140, a fin member 160 provided near the center of the central plate 130, and a support portion 170 that contacts the lower roof member 20 when the edge-cutting member 100 is deformed under pressure. The stopper portion 120 is provided at the rear end of the central plate 130. One end of the fin member 160 is connected to the central plate 130, and the other end projects obliquely downward on the rear side of the central plate 130, that is, in the direction opposite to the insertion direction of the main body portion 110. The support portion 170 is provided near the center between the central plate 130 and the stopper portion 120 and projects downward from the central plate 130. The edge-cutting member 100 is formed of a stainless steel material and is manufactured by bending, cutting, or the like.

[0018] The upper roof member 10 and the lower roof member 20 use roof members of a slate roof.

[0019] The main body portion 110 of the edge-cutting member 100 includes a central plate 130, inclined plates 140, support plates 150, a fin member 160, and a support portion 170, and has a height of about 3.5 mm. Further, a drainage space S for discharging rainwater or the like is formed by the central plate 130, the inclined plates 140, and the support plates 150. By forming a convex shape when the edge-cutting member 100 is disposed, the drainage space S can be enlarged, so that a gap for more reliably discharging rainwater is ensured.

[0020] The central plate 130 is formed such that its tip portion becomes narrower, and when viewed in plan view, the tip portion has a trapezoidal shape. Further, the central plate 130 has a concave through-hole 131 near the center. Also, the thickness of the central plate 130 is constant and smooth without changing depending on the location. When a person steps on it and pressure is applied, the pressure is dispersed over the entire central plate 130, so that the pressure does not concentrate on a specific location, making it easier to prevent damage and further making it easier to deform. Further, inclined plates 140 are formed from both lateral ends of the central plate 130. Note that since the inclined plates 140 are formed by bending a metal plate, the central plate 130 and the inclined plates 140 are integrally formed.

[0021] The inclined plates 140 are provided so as to extend obliquely downward from both lateral ends of the central plate 130, and the inner angle between the central plate 130 and the inclined plates 140 is formed at approximately 150°. Thereby, when pressure is applied, such as when the edge-cutting member 100 is stepped on, it is easily deformed so as to sink. Also, when the inner angle between the central plate 130 and the inclined plates 140 is formed at approximately 150°, a large drainage space S for discharging rainwater and the like can be formed. Note that as the angle, a range of 135° to 165° is preferable. Note that the inclined plates 140 can soften the repulsive strength and smooth the deformation by increasing the number of surfaces.

[0022] The support plate 150 is provided so as to extend slightly upward from the lateral end of the inclined plate 140, and the outer angle between the inclined plate 140 and the support plate 150 is formed at approximately 148°. Thereby, when the edge-cutting member 100 is deformed, such as when stepped on, the tip portion of the support plate 150 can contact and support the upper roofing material 10. Also, by the tip portion of the support plate 150 contacting and supporting the upper roofing material 10, the pressure applied to the edge-cutting member 100 is dispersed, and damage to the edge-cutting member 100 can be prevented. Note that as the angle, a range of 140° to 156° is preferable. Also, the width of the support plate 150 is approximately 2 mm. Also, due to the presence of the support plate 150, it can deform smoothly without being caught by the unevenness on the surface of the roofing material at the end.

[0023] The fin member 160 is provided near the center of the central plate 130 and is formed by utilizing the portion formed by the concave through-hole 131 of the central plate 130. One end of the fin member 160 is connected to the central plate 130, and the other end protrudes downward toward the rear end of the central plate 130. When the other end of the fin member 160 protrudes downward toward the rear end of the central plate 130, it becomes difficult to come off after the edge-cutting member 100 is inserted into the roofing material. Also, one end of the fin member 160 is narrower in width than the other end of the fin member 160. Thereby, while increasing the contact area between the fin member 160 and the lower roofing material 20, the repulsive force of the fin member 160 can be suppressed.

[0024] The support portion 170 is provided near the center between the central plate 130 and the stopper portion 120 and protrudes downward from the central plate 130. Thereby, even if the edge-cutting member 100 is deformed by being stepped on or the like, the support portion 170 contacts the lower roofing material 20, and it is possible to prevent the edge-cutting member 100 from being deformed more than a certain amount. As a result, breakage of the edge-cutting member 100 can be prevented.

[0025] The stopper portion 120 is provided connected to the rear end of the central plate 130, and the angle formed by the central plate 130 and the stopper portion 120 is about 120°. Note that as the angle, a range of 90° to 135° is preferable. Also, since the stopper portion 120 is formed by bending a metal plate, the central plate 130 and the stopper portion 120 are integrally formed. Also, the stopper portion 120 can suppress the reflection of the sun by giving an angle.

[0026] As shown in Fig. 2, the gap between the upper roof member 10 and the lower roof member 20 is approximately 2.5 mm, and the edge-cutting member 100 is disposed in this gap. Since the height from the central plate 130 to the support plate 150 of the edge-cutting member 100 is approximately 3.5 mm, the edge-cutting member 100 is inserted in a deformed state with a slightly sunken shape. Therefore, due to the repulsive force of the edge-cutting member 100, it is difficult to come off. Also, since the fin member 160 also protrudes downward, a repulsive force is generated when the edge-cutting member 100 is inserted. Therefore, if the repulsive force is strong, the upper roof member 10 will be lifted and the gap between the upper roof member 10 and the lower roof member 20 will become large. However, since the base portion of the fin member 160 is formed to be thin, the repulsive force is suppressed and the widening of the gap is prevented.

[0027] Fig. 3 is a view showing a metal plate 200 before processing of the edge-cutting member 100 according to the first embodiment of the present invention. The edge-cutting member 100 is formed by bending a single metal plate 200 shown in Fig. 3. Since it is formed by bending a single metal plate, it has the merit of being easily formed as compared with the case of creating by welding or the like. Also, when formed by bending a single metal plate, the durability and the like are also improved. The length of the metal plate 200 is approximately 40.5 mm and the width is approximately 32 mm.

[0028] FIG. 4 is a diagram showing how the edge-cutting member 100 according to the first embodiment of the present invention deforms. (a) shows the normal insertion state, and (b) shows the state where pressure is applied when the upper roofing material 10 is stepped on by a person and the like, and the edge-cutting member 100 is compressed. The gap in (a) is about 2.5 mm, while the gap in the state of (b) is about 1.3 mm. In the case where the edge-cutting member 100 is in a compressed state, the support portion 170 is in contact with the lower roofing material 20, and the tip of the support plate 150 is in contact with the upper roofing material 10. By supporting the edge-cutting member 100 so that it does not deform beyond a certain level, the effect of preventing damage to the edge-cutting member 100 is exhibited. Further, since the fin member 160 protrudes downward toward the rear end of the central plate 130, when compressed, it tries to move in the direction of being inserted deeper. Therefore, the edge-cutting member 100 has a configuration that makes it difficult to come off. Also, when a person steps on the vicinity of the inserted member with a thickness of about 3 mm inserted between the upper roofing material 10 and the lower roofing material 20, there is no place for the force to escape and it easily cracks. However, since the edge-cutting member 100 according to the present invention has a structure that is compressed to about 1.3 mm, using the edge-cutting member 100 according to the present invention does not lead to damage to the roofing material.

[0029] FIG. 5 is a diagram showing the situation where the edge-cutting member 100 according to the first embodiment of the present invention is inserted when the gap at the overlapping portion between the upper roofing material 10 and the lower roofing material 20 is large. Even when the gap is large, since the fin member 160 is in contact with the lower roofing material 20, the edge-cutting member 100 has a structure that does not come off. Therefore, even when the gap is large, the edge-cutting member 100 according to the present invention can be used. Note that if the repulsive force of the fin member 160 is strong, there is a concern that the gap will widen. However, since one end of the fin member 160 is formed thin, the repulsive force can be suppressed and the gap is less likely to widen. Also, since the other end of the fin member 160 is formed wider than one end of the fin member 160, the contact area between the fin member 160 and the lower roofing material 20 can be increased, resulting in a configuration that makes it difficult to come off.

[0030] Next, the edge cutting member 300 according to the second embodiment of the present invention will be described. FIG. 6 is a view showing the edge cutting member 300 according to the second embodiment of the present invention, and is a view showing (a) a plan view, (b) a side view, and (c) a rear view. FIG. 7 is a view showing a situation where the edge cutting member 300 according to the second embodiment of the present invention is disposed at an overlapping portion of the upper roof member 10 and the lower roof member 20. For FIGS. 6 and 7, detailed descriptions are omitted by attaching the same reference numerals. In the present embodiment, mainly, a configuration different from that of the first embodiment of the present invention will be described.

[0031] The edge cutting member 300 is disposed at an overlapping portion of the upper roof member 10 and the lower roof member 20, and includes a main body portion 110 inserted into the overlapping portion of the upper roof member 10 and the lower roof member 20, and a stopper portion 120 that catches on the lower end portion of the upper roof member 10 and serves as a positioning during insertion. Further, the main body portion 110 includes a central plate 130, inclined plates 140 provided so as to extend obliquely downward from both lateral ends of the central plate 130, a support plate 350 provided so as to extend from the lateral ends of the inclined plates 140, and a fin member 160 provided near the center of the central plate 130. The stopper portion 120 is provided at the rear end of the central plate 130. One end of the fin member 160 is connected to the central plate 130, and the other end protrudes obliquely downward in the rear side of the central plate 130, that is, in the direction opposite to the insertion direction of the main body portion 110. The edge cutting member 300 is formed of a stainless steel material and is manufactured by bending, cutting, or the like.

[0032] The support plate 350 is provided so as to extend upward from the side end of the inclined plate 140, and the inclined plate 140 and the support plate 350 are formed at an angle of about 90°. Thus, when the edge-cutting member 100 is stepped on and deformed, the tip of the support plate 350 can contact and support the upper roofing material 10. Further, by the tip of the support plate 350 contacting and supporting the upper roofing material 10, the pressure applied to the edge-cutting member 300 is dispersed, and breakage of the edge-cutting member 300 can be prevented. Note that as the angle, a range of 90° to 140° is preferable. Also, the width of the support plate 350 is formed short at about 1.3 mm. Further, due to the presence of the support plate 350, it can deform smoothly without the end being caught by the unevenness on the surface of the roofing material.

[0033] Next, a state where the edge-cutting member 300 according to the second embodiment of the present invention is inserted between the upper roofing material 10 and the lower roofing material 20 will be described. FIG. 7(a) shows a situation where it is inserted when the gap between the overlapping portions of the upper roofing material 10 and the lower roofing material 20 is large, FIG. 7(b) shows a state where the edge-cutting member 300 is inserted into a normal gap, and FIG. 7(c) shows a state where pressure is applied as the upper roofing material 10 is stepped on by a person and the edge-cutting member 300 is compressed.

[0034] In FIG. 7(a), even if the gap between the roofing materials is large, since the fin member 160 is in contact with the lower roofing material 20, the edge-cutting member 300 has a structure that does not come off. Therefore, even when the gap is large, the edge-cutting member 300 according to the present invention can be used. Note that when the repulsive force of the fin member 160 is strong, there is a concern that the gap may widen. However, since one end of the fin member 160 is formed thin, the repulsive force can be suppressed and the gap is less likely to widen. Also, since the other end of the fin member 160 is formed wider than one end of the fin member 160, the contact area between the fin member 160 and the lower roofing material 20 can be increased, resulting in a configuration that is difficult to come off.

[0035] In Fig. 7(b), the gap between the upper roofing material 10 and the lower roofing material 20 is approximately 2.5 mm, and the edge-cutting member 300 is disposed in this gap. Since the height from the central plate 130 to the support plate 150 of the edge-cutting member 300 is approximately 3.5 mm, the edge-cutting member 300 is inserted in a deformed state with a slight sinking. Therefore, due to the repulsive force of the edge-cutting member 300, it is difficult to come off. Also, since the fin member 160 also protrudes downward, a repulsive force is generated when the edge-cutting member 300 is inserted. Therefore, if the repulsive force is strong, the upper roofing material 10 will be lifted and the gap between the upper roofing material 10 and the lower roofing material 20 will become large. However, since the base portion of the fin member 160 is formed to be thin, the repulsive force is suppressed and the widening of the gap is prevented.

[0036] In Fig. 7(c), the gap between the upper roofing material 10 and the lower roofing material 20 is approximately 1.3 mm. When the edge-cutting member 300 is in a compressed state, the tip of the support plate 350 contacts the upper roofing material 10 and supports the edge-cutting member 300. By doing so, by supporting the edge-cutting member 300 so that it does not deform beyond a certain level, the effect of preventing damage to the edge-cutting member 300 is exhibited. Also, since the fin member 160 protrudes downward toward the rear end of the central plate 130, when compressed, it tries to move in the direction of being inserted deeper. Therefore, the edge-cutting member 300 is configured to be difficult to come off. Also, if a person steps on the vicinity of the inserted member with a thickness of about 3 mm inserted between the upper roofing material 10 and the lower roofing material 20, there is no place for the force to escape and it will easily break. However, since the edge-cutting member 300 according to the present invention has a structure that is compressed to about 1.3 mm, even if the edge-cutting member 300 according to the present invention is used, it will not lead to damage to the roofing material.

Industrial Applicability

[0037] The edge-cutting member 100 and the edge-cutting member 300 according to the present invention are useful because they can be used during the painting of the roofing material, eliminating the need for edge-cutting by hand and thus reducing the labor.
