Description

  The present invention relates to a metal plate for eaves that prevents intrusion of water from the connecting portion between an outer wall of a structure and an eaves of a sloped roof that extends in an out-of-plane direction from a surface on the outdoor side of the outer wall.

  The connecting part between the outer wall of the building and the sloped roof that extends outward from the outdoor side surface of the outer wall tends to cause water leakage into the interior because rainwater tends to concentrate, especially in the connecting part between the outer wall and the eaves, In order to prevent water leakage, it is common to install a metal plate for eaves that has been processed by sheet metal. These metal fittings are often formed in a complicated shape in which a plurality of metal plates are overlapped due to the nature of the installation position, and a sealing process is applied to an overlapping portion between the metal plates. However, since the water leakage cannot be prevented if the sealing breaks due to aging, etc., a metal plate for eaves has been proposed with a simpler structure than before.

  The invention of Patent Document 1 describes an eaves-end rain metal plate that is formed by bending one sheet metal. This metal plate for rain girder guides the water that has flowed down to the connecting part between the outer wall and the sloped roof to the eaves by the guide groove installed on the eaves side and the front plate part that rises on the outdoor side from the guide groove be able to. In addition, it has a plate-like side plate part that is applied to the surface of the wall base material that is placed on the indoor side of the outer wall. In the unlikely event that rainwater overflows from the eaves, it enters from the joint of the exterior member that constitutes the wall Even if it does, it can flow down along the plate surface of the side plate portion, and rainwater can be guided to the eaves by the guide groove and the front plate portion.

Further, the wall base material 21 is a flat plate-like member that is disposed on the indoor side with respect to the outer wall 2 and is installed on a housing 5 such as a beam or a column that supports the outer wall 2. In the illustrated example, the frame 5 is a wood-based member, but the waterproof structure 4 at the eaves-end portion of the present application can be used even if the frame 5 is a steel frame. Further, the field board 33 is a flat member that is placed on the elongate eaves purlin 34 that supports the eaves of the sloped roof 3 and installed below the roof finishing material (not shown) of the sloped roof 3. . Note that a waterproof sheet (not shown) such as asphalt roofing is attached to the entire surface of the top plate 33 after the eaves-end plate 1 is installed.

  Then, the construction procedure of the waterproof structure 4 of the eaves tip contact part is demonstrated. As shown in FIG. 7, a wall base material 21 is installed in a space surrounded by beams and columns so as to coincide with the in-plane direction of the outer wall 2. The eaves purlin 34 extends in the out-of-plane direction of the wall base material 21, and is arranged with a slight space between the wall base material 21. The eaves purlin 34 is provided with a plurality of suspended timbers 36 that extend in a direction orthogonal to the eaves purlin 34 in plan view to form a roof gradient.

  First, as shown in FIG. 7, a flat eaves iron plate 35 extending in the eave direction is placed on the upper surface of the eaves main house 34. The eaves iron plate 35 is formed to have a width larger than that of the eaves main house 34, and one end in the width direction protrudes from the eaves main house 34 in the direction opposite to the sloped roof 3. A plate piece 35 a extending toward the wall base material 21 is formed at the edge of the protruding portion on the side of the wall base material 21 in the longitudinal direction. At this time, the eaves iron plate 35 is placed on the eaves main house 35 while leaving a space for the eaves edge metal fitting 1 to be installed later on the end of the eaves main house 34 on the wall base material 21 side.

  Subsequently, as shown in FIG. 8, the field board 33 is installed on the upper surfaces of the eaves main house 34, the eaves iron plate 35, and the hanging lumber 36. The base plate 33 has an L-shaped end portion on the wall base material 21 side in accordance with the shape of the eaves iron plate 35 protruding from the eaves main house 34. Then, the plate piece 35 a of the eaves tip iron plate 35 is bent so as to cover the small edge surface of the field plate 33, and the eaves end plate 1 is installed at the joint portion between the wall base material 21 and the field plate 33.

  As shown in FIG. 9, the eaves-end plate 1 is bonded and fixed to the end of the base plate 33 on the wall base material 21 side and the eaves end 31 portion of the base plate 33, and The portion protruding from the wall waterproofing member 12 is arranged so as to be inserted between the wall base material 21 and the eaves purlin 34. Then, the base plate 15a installed on the fixing member 15 is brought into contact with the wall base material 21, and nails, screws, or the like are driven into the portion where the base plate 15a is located from the outdoor side through the fixing member 15, 1 is fixed to the wall base material 21. At this time, the wall waterproofing member 12 is disposed along the surface of the wall base material 21, and the bottom plate 11 c of the box portion 11 a is disposed at a position lower than the installation height of the field support plate 33. .

  The eaves board metal fitting 1 installed in this way can drain water appropriately with the performance of the metal fitting itself even if water W enters the roof finishing material installed on the top of the field board 33. For example, when water W such as rainwater flowing down the connecting portion between the outer wall 2 and the sloped roof 3 enters from the roof finishing material to the waterproof sheet adhered to the upper surface of the field board 33, the water W follows the roof slope. It flows down to the lid 11b of the water receiving member 11. Most of these waters W are prevented from entering the indoors by the lid portion 11b, but when a small amount of water W enters through the joint between the lid portion 11b and the box portion 11a through the lid portion 11b, The water W flows down to the bottom plate 11c of the box portion 11a, and is drained from the gap S to the outside along the inclination of the bottom plate 11c.

  At this time, since the wall waterproofing member 12 is disposed on the indoor side along the surface of the wall base material 21, the water W drained from the gap S is blocked by the wall waterproofing member 12 and enters the indoor. Absent. Further, as described above, the wall waterproofing member 12 protrudes upward from the upper surface of the water receiving member 11 and extends downward from the lower surface of the water receiving member. Therefore, when the eaves-end metal fitting 1 is installed, the water W that has not been received by the box portion 11a of the water-receiving member 11 installed in the eaves 31 is prevented from entering the indoor side by the wall waterproofing member 12, Moreover, the water drained from the gap S flows down along the surface of the wall waterproofing member 12 and does not enter the indoor side from the wall waterproofing member 12.

  As described above, the waterproof structure 4 at the eaves-contacting portion does not depend on the accommodation of waterproof members such as a waterproof sheet or a draining material, and prevents water from entering the interior by the drainage performance of the eaves-end plate 1 itself. Can do. Moreover, even if the seal | sticker of each junction part of the eaves-end metal fitting 1 is cut | disconnected by aged deterioration, the water W can be drained by the clearance gap S formed between the box part 11a and the wall waterproofing member 12. FIG. Therefore, it is possible to prevent water from entering the room.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  The present invention can be suitably used in a connection portion between an outer wall of a structure and an eaves of a sloped roof extending in the out-of-plane direction of the outer wall.
