Description

TECHNICAL FIELD The present invention relates to a mounting structure for an external member, which can be easily and reliably mounted on a roof, and which can prevent displacement due to accumulated snow and flooding due to rainwater or the like.

As a structure for attaching external members such as snow stoppers and lightning rods to various roofs, for example, a structure proposed in Patent Document 1 has been proposed.
The snow stopper (snow stopper A) described in Patent Document 1 is provided with a plurality of fixing holes 4 for screwing in the foot portion 2 along the face plate portion of the roof plate 16, and the lower surface of the foot portion 2 A cover 10 is arranged so as to cover the upper surface of the foot portion 2, and a screw 14 is screwed from the cover 10 into the screw hole 6 provided in the foot portion 2. It is a fixed configuration. Note that the blade portion 1 is an L-shaped portion that dams up snow.
This structure has the advantage that it is not necessary to engage and install the snow guard A while roofing the roof material 16, and the installation work can be easily performed after roofing.

Utility Model Publication No. 2561892

However, in the snow guard A shown in Patent Document 1, the screw hole 6 is formed in the thick bead 5 for reinforcement, so even if the screw 14 is tightened, it does not penetrate the foot portion 2. However, the cover 10 did not have sufficient mounting strength.
Further, for this reason, the cover 10 cannot prevent the foot portion 2 from shifting or rotating when stress is applied to the blade portion 1 of the snow stop A due to accumulated snow or the like. If the cover 10 is displaced by the snow stop A, water intrusion due to snow, rainwater, or the like is likely to occur.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mounting structure for an external member that can be easily and reliably mounted on a roof, and that can prevent displacement due to accumulated snow and flooding due to rainwater and the like.

The present invention has been proposed in view of the above problems. A mounting structure for an external member using a cover material covering from both sides, wherein the support metal fitting includes an external member mounting portion provided at the upper end of the rising portion and a recess recessed toward the underwater side. and the cover material includes a water side insertion part that can be inserted into the recess, and a water side gap that can be inserted into the connecting portion between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage. The present invention relates to a mounting structure for an external member, characterized in that it includes an insertion portion.

Further, according to the present invention, in the mounting structure of the external member, the water side of the fixed surface portion of the support metal fitting is fixed to the face plate portion of the horizontal roof panel via a waterproof material . A mounting structure for external members is also proposed.

In the mounting structure of the external member of the present invention, it is possible to easily and reliably mount the external member to the face plate portion of the horizontal roof shingle. Therefore, it is possible to stably fix an external member such as a snow stopper or a lightning rod to the support fitting.
In addition, since the cover material in this mounting structure is sandwiched between the recess provided in the support bracket and the connecting portion (insertion space) of the horizontal roofing shingles on the upper level and the current level, Even if a stress acts in the floating direction on the external member, the floating of the support member due to the stress is prevented by the two inserts on the water side and the water side of the cover material, so a stable mounting state can be maintained. can be maintained. Alternatively, even if a stress acts from the side, the rotation of the supporting member due to the stress is prevented by the cover material, so that a stable mounting state can be maintained.

In addition, when the water side of the fixing face is fixed to the face plate of the horizontal roofing shingle via a waterproof material, it is also possible to fix it by adopting a simple means such as screwing as the fixing means. It is possible.

The mounting structure of the external member of the present invention consists of a support metal fitting that raises the side end of a fixing surface portion along the face plate portion of the horizontal roof shingle, and the water side of the fixing surface portion of the support metal fitting from above and from the side. The support fitting includes a mounting portion for an external member provided at the upper end of the raised portion, and a recess recessed toward the underwater side. and a water side insertion part that can be inserted into the recess, and a water side insertion part that can be inserted into the connecting portion between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage. Characterized by

Since the support fitting and the cover material are used as a single unit, they are referred to as a "mounting member" in the present invention.
In addition, the connection between the underwater side forming part and the water side forming part of the horizontal roofing shingles that are adjacent to each other in the flow direction is generally formed in a convex shape extending to the water side and a concave shape that opens on the water side. Since this connecting portion is a space that is open on the underwater side and is inserted from the underwater side, it is called an "insertion space" in the present invention.

The support metal fitting forming the mounting member in the present invention is formed by raising the side end of the fixing surface portion along the face plate portion of the horizontal roofing roof plate, and the mounting portion for the external member provided at the upper end of the raised portion. and a recess recessed toward the underwater side. The support fitting may be a molded body made of a metal plate as a raw material as in the illustrated embodiment described later, or may be a molded body of hard resin such as FRP, without being limited to metal.

The fixing surface portion is generally formed along the face plate portion of the horizontal roofing shingle, which is flat in shape, and therefore is often formed in a flat shape, but is not particularly limited.
The raised portion provided on the fixed surface portion is not provided all the way from the underwater end to the upper water end, but refers to the portion (underwater side) covered with the cover material except for the water side. For example, as in the illustrated embodiment described later, a raised portion may be provided from approximately the center to the water bottom end.
Further, the rising portion provided on the underwater side of the fixed surface portion is a vertical piece extending substantially vertically from both right and left ends of the fixed surface portion in the illustrated embodiment described later, and the upper end of one of the vertical pieces extends horizontally. The horizontal portion is used as the mounting portion for the external member. By the way, the other vertical piece serves as a reinforcing portion. In addition, recesses that are recessed toward the underwater side are provided at the lower ends of the upper water ends of the left and right vertical pieces. The concave portion can be inserted from the water side, and although the shape is not particularly limited, it has a depth that allows the underwater side insertion portion of the cover material to remain inserted.

The portion of the fixing surface portion where no rising portion is provided (horizontal piece portion extending to the water side) is the water side that is covered with the cover material from above and from the sides, and fasteners such as screws are driven into it. A plurality of holes may be provided for the purpose.
It is desirable that the water side (horizontal piece portion) of the fixed surface portion closely follows the face plate portion of the horizontal shingle by interposing a waterproof material on the back surface. As the waterproof material, various water-stopping materials can be used, and an elastic water-stopping material (for example, a silicone rubber-based water-stopping material, etc.) may be used in consideration of water-stopping of screw holes. In addition, this waterproof material may be provided not only on the water side but also on the water side. .

The cover material forming the mounting member in the present invention covers the water side of the fixing surface portion of the support fitting from above and from the side in a covering manner, and includes a water side insertion portion that can be inserted into the recess, It has a water side insertion part that can be inserted into the joint between the horizontal roofing shingles of the current stage and the horizontal roofing shingles of the upper stage. It should be noted that this "covering the water side of the fixed surface from above and from the sides" means that the horizontal piece portion of the fixed surface is covered from the upper surface (surface) side, from the water side, and further from the side side. means that it prevents rainwater from entering.

The underwater side insertion portion is provided on the underwater side of the covering portion and is a portion that is inserted from the water side into a concave portion provided in the support fitting. Alternatively, the length may be appropriately set according to the depth of the recess.
The water side insertion portion is provided on the water side of the covering portion, and is a portion that is inserted from the water side into the connection portion (insertion space) between the present stage and the horizontal roofing shingles on the upper stage side.

In the mounting structure using these mounting members (supporting metal fittings and cover materials), the cover material is formed between the concave portion provided in the supporting metal fittings and the connecting portion (insertion space) between the current stage and the horizontal roof shingles on the upper level side. Since the support member is sandwiched between them, even if a stress acts in the floating direction on the external member, the floating of the support member due to the stress will not occur between the two inserts on the water side and the water side of the cover material. Since it is prevented by the part, a stable mounting state can be maintained. Alternatively, even if a stress acts from the side, the rotation of the supporting member due to the stress is prevented by the cover material, so that a stable mounting state can be maintained.

The method for constructing the mounting structure includes a first step of fixing the fixing surface portion of the support bracket to the face plate portion of the horizontal roofing shingle; a second step of tilting the cover material from the underwater side to the connecting portion of the water side so that the water side insertion part faces; The method includes a third step of finely adjusting the cover member in a sliding manner in the direction of flow, and a fourth step of attaching an external member to the attachment portion of the support fitting.

The first step is to fix the support bracket to the face plate of the horizontal roofing shingle, and the fixing means is not limited. may be used for adhesion. In particular, when the water-repellent side of the fixing surface portion is closely attached to the face plate portion via a waterproof material, the waterproof property is improved, and it is possible to fix the fixing surface portion by using screws or the like.

In the second step, the water side insertion part of the cover material is inclined from the water side to the connection part (insertion space) between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage. The tip (upper end) of this upper water insertion portion becomes the fulcrum of rotation in the next third step.

In the third step, the cover material is rotated to fit along the fixing surface of the support fitting, and the cover material is slid finely in the direction of flow of the slope of the roof. It is necessary to form a play space at each of the tip of the underwater side insertion part and the tip of the underwater side insertion part.

The fourth step includes attaching an external member to the attachment portion of the support fitting. Since the attachment portion for attaching the external member is provided at the upper end of the rising portion as described above, the external member such as a snow stopper or a lightning rod can be easily attached. Further, the external member may be attached so as to straddle the attachment portions adjacent to each other on the left and right.

As described above, in the construction method of the mounting structure, any of the first to fourth steps described above can be performed easily and simply without relying on a skilled worker or a worker with strong physical strength. This method is excellent in workability.

The horizontal roofing shingles to which the mounting members of the present invention are attached are not particularly limited, and the face plate portion, the underwater side molding portion provided at the water bottom end, and the water side molding portion provided at the water top end are particularly There are no restrictions on the shape or the like. The same applies to materials. Typically, known metal materials such as surface decorative steel plates, laminated steel plates, plated steel plates, stainless steel plates, aluminum alloy plates, titanium alloy plates, copper plates, etc. with a thickness of about 0.4 to 1.6 mm are used. A material molded into a predetermined shape by roll molding, extrusion molding, or other means can be used as appropriate.
Moreover, the support members and holding members for attaching the horizontal roofing shingles to the base are not limited at all.
