Description

  The present invention relates to an edge-cutting member for edge-cutting a coating film portion of an overlapping portion of a roof material after repainting for the purpose of repairing the roof material.

  Conventionally, roof materials arranged and arranged at equal intervals on a field board are repainted for the purpose of repair because roof materials and their surface portions deteriorate after a long period of time.

  However, when the roofing material is repainted, the overlapping part of the roofing material in the horizontal direction is sealed with the coating film, and rainwater and the like that has entered from the vertical joining part of the roofing material is drained to the lower part in the horizontal direction. Not staying. If the accumulated rainwater is left for a long period of time, the ground plate will be corroded and damaged, leading to leakage of the ceiling.

  For this reason, there is a technique in which after repainting the roofing material, a plate-like member is inserted into the overlapping portion of the roofing material for the purpose of cutting the edge, and then used for a long time.

However, when this edge-cutting member is used for a long period of time and the deterioration is significant, the space of the overlapping portion of the roofing material is increased, and there is a concern that the edge-cutting member is detached.
Furthermore, the conventional edge-cutting member has not taken a method of actively draining rainwater or the like staying around the edge-cutting member.
In addition, there is a concern that the roof material may be damaged when a load is applied such as a person stepping on the outer peripheral portion where the edge cutting member of the overlapping portion of the roof material in which the edge cutting member is inserted is inserted.
Japanese Patent Application No. 2003-388561

  In view of the above-mentioned conventional drawbacks, the present invention uses a roofing material for a long period of time and becomes significantly deteriorated. Even if the space of the overlapping portion of the roofing material increases, the edge cutting member does not come off. Edge drainage that does not cause damage to the roof material even if a load is applied to the outer periphery of the edge cut member inserted into the overlapping part of the roofing material. An object is to provide a member.

The above and other objects and novel features of the present invention will become more fully apparent when read in light of the following description and the accompanying drawings.
However, the drawings are only for explanation and do not limit the technical scope of the invention.

  In order to achieve the above object, the present invention is an edge cutting member that is used while being repainted for roof repairing and is driven into the overlapping portion of the roofing material, and is a plate inserted into the overlapping portion of the roofing material. The roof material edge-cutting member is composed of a body-shaped main body, a separation preventing piece provided on the main body so that the main body does not separate from the overlapping portion of the roof material, and a stopper that performs a predetermined positioning on the front portion of the main body. is doing.

As is clear from the above description, the present invention has the following effects.
(1) A plate-like main body inserted into the overlapping portion of the roof material, which is an edge cutting member used after being repainted for repairing the roof and being driven into the overlapping portion of the roof material, and the main body Since it does not detach from the overlapping portion of the roofing material, it includes a detachment prevention piece provided on the main body and a stopper for performing a predetermined positioning on the front portion of the main body.
For this reason, even if this edge cutting member is driven into the overlapping part of the roof, it is surely set at a predetermined position by the stopper provided at the end of the main body.
In addition, the detachment prevention piece made of an elastic body provided at the bottom of the main body keeps the edge cutting member at the original site even if the space between the roofing materials increases over a predetermined amount due to secular change of the roofing material, and always drains rainwater and the like. To prevent corrosion and breakage of field boards.

(2) In claim 2, the same effect as in the above item (1) is achieved, but the separation preventing piece made of an elastic body provided on the main body is provided with unevenness, and further, separation prevention is provided. Since the projecting convex portion is also provided, the gap between the overlapping portions of the roof increases, and the edge cutting member does not separate from the overlapping portion of the roof even if vibration is applied due to feng shui, earthquake, or the like.
Further, the edge cutting member is adapted to be discharged from a drainage groove provided at a lower portion of the stopper when rainwater or the like flows into a space provided at the center of the main body. For this reason, the drainage of a large amount of rainwater, etc., of course, rainwater etc. does not stay in the overlapping part of the roof, so that it is possible to exclude rainwater etc. from entering the base plate due to capillary phenomenon and causing corrosion and damage.

(3) In claim 3, since the central portion of the main body is thick and the outer peripheral portion of the main body is thin, a person or the like is attached to the outer peripheral portion of the edge cutting member inserted into the overlapping portion of the roofing material. Even if a load is applied locally, such as stepping on the roof, damage to the roofing material can be prevented.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the first embodiment of the present invention shown in FIGS. 1 to 8, reference numeral 1 denotes a roof material edge cutting member, 2 a main body thereof, and 3 a roof material edge cutting member 1 inserted into the roof material overlapping portion 10. It is a stopper to determine the proper position when doing.

  A separation preventing piece 4 and a separation preventing convex portion 5 are provided so that the edge cutting member 1 does not separate from the overlapping portion 10 of the roof material.

  The material applied to the edge cutting member 1 is preferably a resin material that is easy to process.

  The roofing material 9 is ready for repainting when about 7 to 8 years have passed. After repainting, the edge cutting member 1 is inserted so that rainwater or the like does not stay in the overlapping portion 10 of the roofing material. However, when the paint is repainted for a longer period of time, a gap is generated in the overlapping portion 10 of the roof material due to deterioration of the roof material, and the value tends to increase. When 10 years have passed since the use of the roofing material, the gap between the overlapping parts of the roofing material (C in FIG. 10) may be 7 to 8 mm in an area of high temperature, high humidity and bad environment. For this reason, since the conventional edge cutting member inserted in the overlapping part 10 of the roofing material can only respond to the gap of about 4 mm, there is a concern of detachment.

In order to prevent detachment, the edge cutting member 1 of the present invention is provided with a detachment preventing piece 4 on the main body.
The separation preventing piece 4 is a plate-like member having elasticity below the main body 2, and one or a plurality of concave and convex shapes are formed at a portion in contact with the roof material 9.
The edge cutting member 1 is set so that the separation preventing piece 4 has elasticity and can sufficiently follow the gap of the overlapping portion 10 of the roof even if the gap of the overlapping portion 10 of the roof increases more than expected. Therefore, it will not leave.
Although the separation preventing piece 4 of the present invention is provided below the main body 2, it can also be provided above.

As shown in FIG. 4, a plurality of detachment prevention convex portions are provided at the lower portion of the main body 2 of the edge cutting member 1.
The cross-sectional shape is shown in FIG. The cross-sectional shape may be triangular, but the wedge shape enhances the separation preventing effect.

Further, the edge cutting member 1 is provided with a drain groove 7 at the bottom of the stopper 3 as shown in FIG. The drainage groove 7 immediately drains when rainwater or the like gathers in the vicinity of the edge cutting member 1 and stays in the drainage storage space 6 shown in FIG.
Thus, since this edge cutting member 1 does not retain rainwater or the like, it is possible to prevent the base plate 13 from being corroded or damaged by a capillary phenomenon.

  FIG. 9 shows a portion where the edge cutting member 1 is mounted on the roof.

  FIG. 10 shows a state where the edge cutting member 1 is mounted on the overlapping portion 10 of the roof.

  In order to insert the edge cutting member 1 into the overlapping portion 10 of the roof material, a small amount of the tip of the edge cutting member 1 is inserted into the overlapping portion 10 of the roof material, and then a load is applied to the end surface of the stopper 3 manually or with a jig. Can be easily inserted by applying.

Different forms for carrying out the invention

  Next, different modes for carrying out the present invention shown in FIGS. 11 to 15 will be described. In the description of these different modes for carrying out the present invention, the same components as those in the first mode for carrying out the first embodiment of the present invention are designated by the same reference numerals and redundant description is omitted. To do.

In the second embodiment of the present invention shown in FIGS. 11 to 15, the difference from the first embodiment is that the central part of the main body is thick, and the inclined shape becomes closer to the tip part and the side part. Is taking.
In this way, when the main body 2 of the main edge cutting member 1 is inserted into the overlapping portion 10 of the roof by making the thickness of the main body inclined, as shown in FIG. Since it is thin, cracks and breakage of the roofing material 9 can be eliminated even if an excessive load is applied locally, such as when a person steps on it.

  When the central portion, the front end portion, and the side surface portion of the main body 2 of the conventional edge cutting member 1 have the same thickness, a person steps on the edge cutting member 1 inserted into the overlapping portion 10 of the roofing material with a foot or the like. When the excessive load is applied, the roofing material 9 is cracked and broken as shown in FIG. 14, and the base plate 13 is corroded and broken due to intrusion of rainwater or the like.

    The present invention is utilized by the industry that manufactures roofing materials and the traders who repaint roofing materials.
