Description

The present invention provides a mounting structure for an external member that can easily and reliably attach an external member such as a snow stopper or a lightning rod to a roof, and that can prevent, for example, slipping due to accumulated snow and flooding due to rainwater. related to its construction method.

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 Registration 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.

Therefore, the present invention provides a mounting structure for external members that can easily and reliably attach external members such as snow stoppers and lightning rods to the roof, and that can prevent, for example, movement due to accumulated snow and inundation due to rainwater and the like. , and its construction method.

The present invention has been proposed in view of the above, and provides a mounting structure using an external member having a vertical piece perpendicular to the slope of the roof surface and a horizontal piece along the face plate of the horizontal roof shingle. A method of construction in which a cover material is used to cover the water side and side of the lateral piece of the external member, and the cover material is a water plug that can be inserted into a hole provided in the external member. A bottom insertion part 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, wherein the face plate part of the horizontal roofing shingle a first step of fixing the horizontal piece portion of the external member; a third step of rotating the cover member so that the underwater side insertion portion faces the hole provided in the external member; and a third step of rotating the cover member to face the hole. a fourth step of finely adjusting the cover material in a sliding manner in the direction of flow of the roof slope in a state in which the underwater side insertion part is inserted and the horizontal piece part is covered;
The present invention relates to a construction method for a mounting structure for an external member, characterized by comprising :

Further, according to the present invention, in the construction method described above, the lateral piece of the external member is fixed to the face plate of the horizontal roof shingle via a waterproof material. We also propose a method .

In the construction method for the mounting structure of the external member of the present invention, any of the first to fourth steps does not depend on a skilled worker or a worker with strong physical strength, and therefore can be easily and simply carried out. , which is a method with excellent workability. In addition, the external member can be easily and surely attached to the face plate portion of the horizontal roofing roof plate, and the cover material can reliably prevent the infiltration of rainwater and the like. The installation member can be stably fixed. Furthermore, since the cover material in this mounting structure is sandwiched between the hole provided in the external member and the connecting portion (insertion space) of the horizontal roofing shingles of this stage and the upper stage. Even if a stress acts on the vertical piece in a lifting direction, the lifting of the external member due to the stress is prevented by the two inserts on the water side and the water side of the cover material. status can be maintained. Alternatively, even if a stress acts from the side, the rotation of the external member due to the stress is prevented by the cover material, so that a stable mounting state can be maintained.

In addition, when the horizontal piece of the external member is fixed to the face plate of the horizontal roofing shingle through a waterproof material, it is easy to adopt a simple means such as screwing as the fixing means. can also be fixed to

A method for constructing a mounting structure for an external member according to the present invention is a mounting structure using an external member having a vertical piece perpendicular to the slope of the roof surface and a horizontal piece along the face plate of the horizontal roof shingle. in which a cover material is used to cover the water side and side of the lateral piece of the external member, and the cover material can be inserted into a hole provided in the external member. A water side insertion part and a water side insertion part that can be inserted into the connection part between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage , and the face plate part of the horizontal roofing shingle a first step of fixing the lateral piece of the external member; and inserting the water side inserting portion of the cover material into the connecting portion between the horizontal roofing shingle of the current stage and the horizontal roofing shingle of the upper stage. a second step; a third step of rotating the cover material to face the underwater side insertion portion in the hole provided in the external member; rotating the cover material to face the hole; and a fourth step of finely adjusting the cover material in a sliding manner in the flow direction of the roof slope in a state in which the underwater side insertion part is inserted and the horizontal piece part is covered.

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 external member in the present invention has a vertical piece perpendicular to the slope of the roof surface and a horizontal piece along the face plate of the horizontal roof shingle. or a metal lightning rod or the like.
Further, the external member is provided with a hole into which the underwater side insertion portion of the cover material can be inserted. Although this hole is formed as an elongated hole at the intersecting corner of the vertical piece and the horizontal piece in the illustrated embodiment described later, the shape and the like are not particularly limited.

Since the horizontal piece portion is generally formed along the face plate portion of the flat plate-shaped horizontal roofing shingle, it is often formed in a flat shape, but it is not particularly limited.
This horizontal piece is a portion that is covered with the cover material from above and from the sides, and is present on the water side of the snow stopper. You may make it provide.
In addition, it is desirable that the horizontal piece portion is closely fitted to the face plate portion of the horizontal roofing shingle by interposing a waterproof material on the back surface thereof. 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.

The vertical piece is perpendicular to the slope of the roof surface and is present on the underwater side of the horizontal piece. It may be formed by rising to
As shown in the illustrated embodiment using a snow stopper as an external member to be described later, this vertical piece has a dam plate that increases the damming effect of the snow flow. The dam may be fixed to increase the damming action.
In addition, since this vertical piece receives the pressure of the snow flowing along the slope of the roof surface, it is made of materials that do not cause deformation due to the pressure of the snow, for example, the metal plate molding material as described above, or the like. It is desirable to use FRP or the like, but it is also desirable that the shape and configuration is molded so as to have a plurality of ribs, for example.

The cover material in the present invention covers the water side of the horizontal piece of the external member from above and from the side in a covering manner, and is an underwater side insert that can be inserted into the hole provided in the external member. and a water side insertion part that can be inserted into the joint between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage. It should be noted that this "covering the water side and side of the horizontal piece" means that the horizontal piece is covered from the upper surface (surface) side, from the water side, and further from the side side. It means to prevent flooding.

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 hole provided in the external member, and is formed in accordance with the hole shape. The length may be appropriately set according to the hole depth.
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.

The mounting structure of the external members using these external members and the cover material is that the cover material connects the hole provided in the external member and the connecting part (insertion space) between the roof shingles on the current stage and the upper stage. Therefore, even if a stress in the lifting direction acts on the vertical piece, the lifting of the external member due to the stress is limited to the two sides of the cover material, the underwater side and the water side. Since it is prevented by the two insertion parts, a stable mounting state can be maintained. Alternatively, even if a stress acts from the side, the rotation of the external member due to the stress is prevented by the cover material, so that a stable mounting state can be maintained.

Further, the present invention is a method for constructing the mounting structure for the external member, comprising: a first step of fixing the lateral piece portion of the external member to the face plate portion of the horizontal roof shingle; a second step of inserting the water side insertion portion of the covering material into the connecting portion between the roofing shingle and the horizontal roofing shingle on the upper level side; a third step of exposing the lower insertion portion; rotating the cover material to insert the underwater side insertion portion into the hole and covering the horizontal piece portion; and a fourth step of finely adjusting in a sliding manner.

In the first step, the external member is fixed to the face plate portion of the horizontal roofing shingle, and the fixing means is not limited. Adhesion using, etc., may also be used. In particular, when the water side of the back surface of the horizontal piece portion is closely fitted to the face plate portion via a waterproof material, the waterproof property is improved, and it is also possible to fix it by using a screw or the like.

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

In the third step, the cover member is rotated to face the underwater side insertion portion in the hole provided in the external member. The inner end (upper water end) is the upper water insertion portion as described above, and the outermost end of rotation is the lower water insertion portion (lower water end).

In the fourth step, the cover material is rotated to insert the underwater side insertion part into the hole and cover the horizontal piece part, and finely adjust the cover material in a sliding manner in the flow direction of the roof slope. However, it is necessary to provide play spaces at both the tip of the above-water insertion part and the tip of the below-water insertion part.

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

In addition, the horizontal roofing shingles to which the external members are attached in the present invention are not particularly limited. There are no particular 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.
Further, the supporting members for attaching the horizontal roofing shingles to the base and the holding members such as hangers are not limited at all.

The substrate 4 on which the heat insulating material 5 is laid is a board-like wood wool cement board or the like laid on the frame 7 arranged along the slope (roof slope). A sheet material 4b is laid.

The procedure for constructing the snow guard structure of the first embodiment will be described below with reference to FIGS. 3(a) to 3(d).
First, as a first step, as shown in FIG. A fixing bolt 1d is driven into the hole 121 and fixed. At this time, since the waterproof material 1c is attached to the back side of the horizontal piece 12, it is fixed to the face plate part 61 in close contact via the waterproof material 1c. This waterproof material (water stop material) 1c prevents it. In FIG. 3(a), the cover material 2 is attached to the connecting portions 62 and 63 between the horizontal roofing shingles 6 of this stage and the horizontal roofing shingles 6 of the upper stage so that the water side insertion portion 23 is downward. It shows a state in which it is tilted so that

Next, as a second step, as shown in FIG. 3(b), the water side insertion part 23 of the cover material 2 is connected to the horizontal roofing shingle 6 of this stage and the horizontal roofing shingle 6 of the upper stage. It is inserted into the parts 62 and 63 from the underwater side. The tip (lower end) of the water side insertion portion 23 becomes the fulcrum of rotation in the next third step.

Subsequently, as a third step, as shown in FIG. The insertion part 22 is made to face. The innermost end of this rotation (above the water end) is the above-water insertion portion 23 as described above, and the outermost end of this rotation is the below water insertion portion 22 (underwater end).
