Description

The present invention relates to a mounting structure for external members such as snow stoppers and lightning rods, which can be easily and reliably mounted on a roof, and which can prevent, for example, movement due to accumulated snow and flooding due to rainwater.

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. The purpose is to propose

The present invention has been proposed in view of the above, and is a mounting structure using an external member provided with a vertical piece perpendicular to the slope of the roof surface and a horizontal piece along the face plate portion of the horizontal roof shingle. A cover material having a covering portion that covers the water side and side of the horizontal piece portion of the external member is used, and the cover material is provided between the vertical piece portion and the horizontal piece portion of the external member. The underwater side insertion part that can be inserted into the hole provided in the boundary and the 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 are described above. The present invention relates to a mounting structure for an external member, characterized by being formed on the edge of a covering portion.

The present invention also proposes a mounting structure characterized in that, in the mounting structure, the lateral piece of the external member is fixed to the face plate of the laterally roofing shingle via a waterproof material.

The mounting structure of the external member of the present invention allows the external member to be easily and reliably mounted to the face plate portion of the horizontal roof shingle. Since the covering material having the covering portion that covers the sides in a covered manner can reliably prevent this, external members such as snow stoppers and lightning rods can be stably fixed.
In addition, the cover material in this mounting structure is a hole provided at the boundary between the vertical piece and the horizontal piece of the external member, and the connecting portion (insertion space) between this stage and the horizontal roof shingles on the upper stage side. Since the external members are sandwiched between them, even if a stress acts on the vertical pieces in a lifting direction, the lifting of the external member due to the stress is prevented by the water formed on the edge of the covering portion of the cover material. Since this is prevented by the two insertion parts on the lower side and the upper side of the water (underwater side insertion part and upper water side insertion part), 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.

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

The mounting structure of the external member of the present invention is a 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 portion of the horizontal roof shingle, A cover material having a covering portion that covers the water side and side of the horizontal piece portion of the external member is used, and the cover material is provided between the vertical piece portion and the horizontal piece portion of the external member. The underwater side insertion part that can be inserted into the hole provided in the boundary and the 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 are described above. It is characterized in that it is formed at the edge of the covering portion.

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. This hole is formed as an elongated hole at the crossing corner (boundary) between the vertical piece and the horizontal piece, but 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 according to the present invention includes a covering portion that covers the water side of the horizontal piece portion of the external member from above and from the sides, and is capable of being inserted into the hole provided in the external member. A lower inserting portion and a water upper inserting portion which can be inserted into the connecting portion between the horizontal roofing shingle of this stage and the horizontal roofing shingle of the upper stage are formed at the edge of the covering portion. 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 member using these external members and the cover material is such that the cover material has a hole provided at the boundary between the vertical piece portion and the horizontal piece portion of the external member, and the horizontal Since it is sandwiched between the connection part (insertion space) of the roof shingle, even if a stress acts on the vertical piece in a lifting direction, the external member will not rise due to the stress. Since this is prevented by the two insertion portions on the water side and the water side of the cover material, 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.

In addition, the method for constructing the mounting structure of the external member includes a first step of fixing the horizontal piece portion of the external member to the face plate portion of the horizontal roofing shingle; a second step of inserting the water side insertion portion of the cover material into the connection portion with the horizontal roofing shingle; and rotating the cover material to insert the water side insertion portion into the hole provided in the external member. a third step of placing the cover material in front; and rotating the cover material 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 direction of flow of the roof slope. and a fourth step.

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.

Note that the covering portion 21 is a substantially bag-like portion that covers the horizontal piece portion 12 from the upper surface (surface) side, from the water side, and from the lateral side, and can prevent rainwater and the like from entering. . In addition, the underwater side insertion portion 22 is formed in a claw shape with a width slightly smaller than that of the oblong hole 10, and the water side insertion portion 23 is formed as shown in FIG. 1(c). It is formed to have a width substantially equal to the width of the cover material 2 .

Next, each member constituting the horizontal roof structure to which the snow guard structure shown in FIG. 1 is applied will be briefly described below.
As shown in FIG. 4(c), the horizontal roof shingles 6 are composed of a face plate portion 61 bent in a dogleg shape on the underwater side, and an underwater plate portion 61 with the underwater end bent to the back side and extending to the water side. A side forming portion 62, a water side forming portion 63 formed by bending the water end of the face plate portion 61 toward the surface side and extending to the water side, and a U-shaped fitting portion 64 formed on the water side. The horizontal roof panels 6, 6 adjacent to each other in the flow direction are connected by engaging the underwater side molding portion 62 and the water side molding portion 63. As shown in FIG. A backing material 6b is attached to the back side of the face plate portion 61 and the water side forming portion 63. As shown in FIG.

The heat insulating material 5 laid on the back side of the horizontal roofing shingle 6 is a non-permeable expanded polystyrene having a projecting portion 52 whose surface layer portion extends to the underwater side at the underwater end. The heat insulating material 5 is formed so that the body portion 51 gradually becomes thinner from the underwater side to the underwater side, and a lower overlapping portion 53 that is assembled with the projecting portion 52 in an overlapping manner is formed at the upper water end. The lower water end (protruding portion 52) and the upper water end (lower overlapping portion 53) are connected to each other in a phase-locking manner.
In FIG. 4B, since the horizontal roofing shingles 6 are omitted, the surface side of the main body 51 of the heat insulating material 5 can be seen, but a large number of island-like portions 511a and 511b and joint protrusions 513 are provided. The formation interval (gap) between them is used as the drain groove 512 . The island-shaped portions 511a and 511b are each formed in the shape of a head of a thick arrow when viewed from above, but two types of island-shaped portion 511a with a wide width and island-shaped portion 511b with a slightly narrow width are provided. ing.
Further, the lower overlapping portion 53 on the water side of the main body portion 51 of the heat insulating material 5 is formed continuously in the left-right direction, but the projecting portion (upper overlapping portion) 52 extending to the underwater side does not project. formed into pieces.

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).

Then, as a fourth step, as shown in FIG. Then, the cover member 2 is slid finely.

The constructed snow guard structure of the first embodiment has the following effects.
The snow guard 1 can be easily and surely attached to the face plate part 61 of the horizontal roof board 6, and the cover material 2 can surely prevent the infiltration of rainwater or the like, so that the snow guard 1 is stabilized. can be fixed to
Also, the cover material 2 in this snow stopper structure is sandwiched between the hole 10 provided in the snow stopper metal fitting 1 and the connecting portion (insertion space 65) of the roof board 6 on the side of this stage and the upper stage. Therefore, even if a stress in the lifting direction acts on the vertical piece 11, the lifting of the snow guard 1 due to the stress is caused by the two insertion portions on the underwater side and the water side of the cover material 2. Since it is prevented by 22 and 23, a stable mounting state can be maintained. Alternatively, even if stress acts from the side, the snow stopper 1 is prevented from rotating by the stress by the cover material 2, so that a stable mounting state can be maintained.

In this first embodiment, the horizontal piece 12 of the snow guard 1 is fixed to the face plate 61 of the horizontal roof panel 6 via the waterproof material 1c. It is also possible to fix easily by adopting a simple means such as.

Furthermore, although the wide dam 3 is fixed to the vertical piece 11 of the snow stopper 1, a dam that straddles the vertical pieces 11 of a plurality of snow stoppers 1, for example, may be used. In this case, a laterally elongated weir can be attached to enhance snow protection.
