Description

  The present invention relates to an eaves arabesque that can reliably guide rainwater to a rain gutter and in which an eave edge of a base material such as a field plate or a slate plate does not get wet and deteriorate, and an eaves structure using the eaves.

As the eaves end structure of the metal roof plate, a structure in which a substantially T-shaped arabesque is nailed to the eaves edge of a field plate or a slate plate is widely used.
For example, Patent Document 1 proposes an eaves arabesque in which a vertical piece hangs substantially vertically from a horizontal piece laid on a field board.
Moreover, the eaves arabesque described in Patent Document 2 has been proposed to have a structure in which vertical pieces of eaves arabesque are arranged along a draining board.
Furthermore, Patent Document 3 also describes an eaves tip fixing member having a vertical piece that is substantially vertical.

Japanese Utility Model Publication No. 4-76847 (FIG. 1) Japanese Patent No. 2715063 (FIGS. 1 and 3) Japanese Utility Model Publication No. 53-120422 (FIG. 1)

  The conventional eaves arabesque has been proposed as a structure that is unlikely to cause water leakage due to intrusion of rainwater, but has not yet achieved sufficient effects. For example, in eaves arabesque described in Patent Document 1, rainwater is blown onto the back surface of the field board by blowing up from the eaves side. Moreover, in patent document 2, since the lower side of the eaves arabesque is made to follow a draining board, direct spraying of rainwater can be prevented, but rainwater also infiltrates from a gap with the draining board also by a capillary phenomenon. Furthermore, in Patent Document 3, as in Patent Document 1, rainwater is sprayed on the back surface of the field board by blowing up from the eaves side, but the rainwater is collected in the corners of the substantially U-shaped space. If rainwater accumulates in this way, rainwater and the eaves edge lower part of a field board will contact, and the eaves edge of a field board will become a wet state, and will deteriorate remarkably. Especially in small and medium-sized buildings (houses, apartment buildings, etc.), structural plywood is often used as field material, and in that case, the eaves of the field material is likely to be corroded (deteriorated) by blowing into rainwater. . And if a field board corrodes, the fixed strength of fixing tools, such as a screw which fixes the eaves arabesque, will fall, and the intensity of the eaves as a building will fall as a result.

  Therefore, the present invention can eliminate the above-mentioned problems, can reliably guide rainwater to the gutter, and the eaves edge of the base material such as a field board or a slate board may get wet and deteriorate. The purpose is to propose an eaves arabesque with no eaves and an eaves structure using it.

  The present invention has been proposed in view of the above, and there is an eaves arabesque used for an eave side end portion of a roof structure in which an exterior material is laid on the surface of a base material, a flat portion, and a back surface of the flat portion A drooping portion that hangs down from the side and has a lower end formed in a protruding shape toward the eaves side, a return portion that forms a space from the lower end of the drooping portion and forms the space portion, and is directed upward on the ridge side, and the flat portion. The eaves side arabesque is provided with an eaves side flat part extending from the upper end of the hanging part to the eaves side.

  Further, the present invention is an eaves structure using eaves arabesque at the eave side end of the roof structure in which an exterior material is laid on the surface of the base material, and the eaves arabesque is arranged in the surface direction of the base material. The ridge side, forming a space portion with the flat portion that hangs down from the back surface side of the flat portion, the lower portion formed in a protruding shape on the eave side, and the protruding portion from the lower end of the hanging portion An eaves-side flat part extending from the flat part toward the eaves side from the upper end of the hanging part from the flat part, and the eaves end of the base material is in contact with and attached to the hanging part, Also proposed is an eaves tip structure using eaves arabesque, wherein the eaves side end of the exterior material is engaged with the eaves end of the side flat part, and the exterior material is laid on the flat part. .

In the eaves arabesque of the present invention, the lower end of the hanging part hanging down from the back side of the flat part laying the base material such as field board or slate board protrudes toward the eaves side, so that rainwater sprayed on the eaves Can lead to.
Furthermore, since the space part formed by the lower end of the drooping part and the return part has a shape protruding toward the eaves side, even if rainwater collects in this space part, the rainwater and the lower part of the eaves end of the base material contact each other. And the base material is not deteriorated. And the fixed strength of eaves arabesque can be stably maintained by preventing deterioration (corrosion) of a base material.

  The eaves structure of the present invention uses the eaves arabesque as described above, and does not cause deterioration due to the wetness of the base material as described above. There will be no.

  In particular, when the upper end of the return portion is supported by contacting the back surface of the base material, it can be easily and stably attached even when the base material is mounted.

An eaves arabesque 1 which is an embodiment of the present invention shown in FIG. 1 includes a flat portion 11, a hanging portion 14 that hangs down from the back surface side of the flat portion 11, and whose lower end (141) is formed in a protruding shape on the eave side. A return portion 16 that extends upward from the lower end of the drooping portion 14 toward the ridge side while forming a space portion 17 with the protruding portion 141, and extends from the flat portion 11 to the eaves side from the upper end of the drooping portion 14. It is the structure provided with the eaves side flat part 12 to do.
And the characteristic structure is that the lower end 141 (curved portion protruding in a curved shape) of the drooping portion 14 is formed in a protruding shape on the eave side (the left side in the drawing), and the protruding portion 141 is spaced from the lower end. It is the structure which provided the return part 16 which goes to a ridge side upper direction, forming a part. In the illustrated embodiment, the protruding portion 141 in which the lower end of the drooping portion 14 is formed in a protruding shape on the eaves side is a curved warped portion. However, an inclined piece protruding to the eaves side may be used. The shape may be a bent piece that is bent once or twice or more, and is not particularly limited.

The eaves arabesque 1 of the present invention shown in FIG. 1 has a configuration in which the lower end 141 of the hanging part 14 is formed in a protruding shape toward the eaves side, so that the rainwater sprayed can be smoothly guided to the rain gutter.
On the other hand, since the conventional eaves arabesque (for example, in Patent Documents 1 and 3) has a configuration in which the vertical pieces hang from the back side of the flat portion in a substantially vertical shape, when the rainwater falls into the gutter, Rainwater was sometimes sprayed on the back of the base material by blowing up from the side.
In addition, 121 in the figure is a drainage groove formed on the surface side of the eaves side flat portion 12 and is formed for the purpose of draining rainwater that has entered by capillary action in the drainage groove 121. Reference numeral 13 in the figure denotes an engagement piece obtained by bending the eave end of the eaves side flat part 12 downward, and engages an eaves side molding part 32 of the exterior material 3 to be described later.

  The eaves arabesque 1 of the present invention is not particularly limited in its material, but preferably uses an extruded aluminum material, a coated steel plate, a plated steel plate, a stainless steel plate, a painted stainless steel plate, etc. excellent in corrosion resistance and durability. In addition, since the shape is simple, the cost required for producing the member can be kept low.

  FIG. 2 (a) is an embodiment showing an eaves structure using the eaves arabesque 1, and has a roof structure in which an exterior material 3 which is a vertical roofing board is laid on the surface of a field board 5 made of plywood or the like. This is an eaves structure using eaves arabesque 1 at the edge of the eaves.

In this eaves-end structure, the base material 6 is laid in a state where the back surface is supported by the housing 7. The upper end of the return portion 16 is disposed so as to be in contact with and supported by the back surface of the base material 6. The base material 6 is not particularly limited to a material such as a plywood board, a wooden board, or a hard heat insulating board, and a known material can be used as the base material 6 disposed on the back surface of the roof material.
As apparent from FIG. 2, even if rainwater accumulates in the space 17 formed by the protruding portion 141 and the return portion 16, the corner of the eaves protrudes to the eaves side, and the rainwater and the base material 6 Since there is no contact with the lower end of the eaves, no deterioration occurs.
On the other hand, in the conventional eaves arabesque (for example, in Patent Document 3), since the space portion is formed in a substantially U shape, when rainwater accumulates at the corner, the rainwater comes into contact with the lower end of the eaves of the base material. As a result, the edge of the eaves of the base material may become wet and deteriorate significantly.

  On the eaves arabesque 1 attached to the eaves edge of the base material 6, a waterproof sheet (represented by a one-dot chain line in the drawing) such as asphalt roofing, roofing felt or rubber sheet is laid and flattened by a fixture 18 from above. The part 11 is fastened and fixed to the housing 7.

  Furthermore, the exterior material 3 is laid on the flat portion 11 while the eave end (engagement portion 13) of the eave side flat portion 12 of the eaves arabesque 1 is engaged, thereby constructing a roof structure.

The roof structure in this embodiment is an exterior structure using a vertical roofing board (exterior material 3) with the left and right side edges raised as shown in FIG. 2 (b). This exterior structure includes an exterior material 3, a holding member 4, and a cap material 5, and will be briefly described below.
The exterior material 3 is provided with a concave groove that is recessed downward at the base ends of the left and right side edges, and further, is provided with a raised portion that protrudes upward on the outer side, and the left and right leg pieces of the cap material 5 are provided on the raised portion. The lower end is in contact with the contact surface, and may be a continuous material in the flow direction, or a fixed-size exterior material connected using a well-known connecting structure. Surface-coated steel sheet, laminated steel sheet, plating Formed from known metal materials such as steel plate, stainless steel plate, aluminum alloy plate, titanium alloy plate, copper plate, brass plate, lead plate, etc., carbon fiber laminated plate, hard resin plate, etc. Roll forming when the material is metal plate Alternatively, it is molded (molded) by press molding or a combination of both.
The holding member 4 that holds the exterior material 3 on the ground includes a fixing portion to the ground, a retaining portion that holds the left and right side edges of the exterior materials 3 and 3, and an engaged portion that engages the cap material 5. Have The holding member 4 may be a short piece material or a long piece. The exterior member 3 is exposed to the retaining member 4 fixed to the base, and then a part of the retaining member 2 is deformed to provide an exterior. The left and right edges of the material 3 are held.
The cap member 5 covering the left and right side edges of the left and right exterior members 3, 3 has an inverted V-shaped cover part and an inward substantially square-shaped engagement with the engaged part of the holding member 4. And a leg piece that expands left and right when the cap material 5 is laid. The cap material 3 may be a threading material that is continuous in the flow direction as in the case of the exterior material 3, or may be one in which a fixed-length exterior material is connected using a known connection structure, and is similar to the exterior material 3. What is necessary is just to form with a raw material.

On the upper part (near the upper end) of the housing 7, an eave jar composed of two members, a decorative candy material 8 and an outer frame material 9, is fixed so as to face the eaves arabesque 1.
Therefore, the rainwater sprayed on the drooping portion 14 of the eaves arabesque 1 is guided and drained from the lower end (protruding portion) 141 protruding to the eaves side into the eaves bowl.

Since the eaves structure having the above-described structure uses the eaves arabesque 1 described above, it is possible to smoothly guide rainwater sprayed to the hanging part 14 to the rain gutter.
On the other hand, in the conventional eaves arabesque, in the laying state, the hanging part formed vertically is arranged to incline toward the ridge side, that is, the base material side, and the rainwater sprayed is Since it is easy to go around from the lower end to the base material side, rainwater may be sprayed on the back surface of the base material without being guided to the gutter. And, when the base material is corroded (deteriorated) by rainwater, the fixing strength of a fixing tool (such as a screw) that fixes the eaves arabesque decreases, and as a result, the strength of the eaves as a building may decrease. .
In addition, since the eaves end structure of the present invention has a shape in which the space portion 17 protrudes toward the eave end side, even if rainwater accumulates in this space portion 17, the rainwater does not contact the eaves end lower portion of the base material 6, The fixing strength of the eaves arabesque can be stably maintained without causing corrosion (deterioration) due to wetting of the base material 6.
