Description

  The present invention relates to an eaves rod suspension fitting, and more particularly, when the eaves rod support member is attached to the folding roof, the vertical position adjustment of the eaves rod support member is simple, and the eave cage is attached to the folding plate without difficulty. The present invention relates to an eaves-hanging metal fitting that prevents a suspension bolt from being bent and a folded roof from being damaged when an external force or vibration such as wind and snow is applied to the eaves.

  Buildings such as factories, warehouses, cattle barns, poultry farms, parking lots, roadside stations, vegetable sales offices, sports facilities, and simple houses have roofs bent metal plates and plastic plates, and the mountains and valleys are W-shaped. In many cases, it is covered with an origami roof that has a continuous cross-sectional shape. Origami roof is a typical metal roof with design, strength and economy that harmonizes with large and long roofs, and roofing materials can be directly applied to beams and main houses. It is also said that it can respond to shortening of the construction period and exhibits toughness in strong winds and heavy snowfalls.

  There are various eaves hanging brackets or support structures for attaching the eaves to the eaves of the engraved roof, but a typical one is that a nut is screwed onto the mountain of the engraved roof at the upper end of the suspension bolt. And fixed to the eaves supporting member at the lower part of the suspension bolt by screwing the nut.

  However, in such a conventional eaves supporting member, when a lateral external force such as strong wind is applied to the eaves attached to the folding roof, the suspension bolt is attached to the folding roof. Since bending stress with the upper end portion as a fulcrum is generated, there is a problem that the suspension bolt is easily bent. In addition, since stress is generated in the folded roof on the portion where the suspension bolt is fixed, the folded roof may be damaged.

  In order to improve this, Patent Document 1 describes a hanging bolt whose upper end is fixed to a mountain portion of a folded roof or an intermediate portion between a mountain portion and a valley portion, and an eaves can be supported attached to the lower end of the hanging bolt. The eaves rod supporting member formed in a simple shape, and an abutting plate attached to the middle portion of the suspension bolt and formed in a shape capable of abutting both ends on the lower surface of the valley portion of the folding roof An eaves support member has been proposed.

  Conventionally, the upper end of the suspension bolt is fixed to the peak portion of the folding roof by nut screwing and is only fixed to the eaves supporting member at the lower portion of the suspension bolt by screwing the nut. At a middle position between the position fixed to the peak portion of the folding roof by nut screwing and the position fixed to the eaves supporting member at the lower part of the suspension bolt by 90 ° with respect to the direction of the suspension bolt. At both angles, both ends of the contact plate are fixed to the lower surface of the valley portion of the folding roof. As a result, even if a lateral external force is applied to the eaves with the eaves attached to the folding roof, the hanging bolts are not bent while the external force is small, and the folding roof is not easily damaged.

  However, in the invention of Patent Document 1, the contact plate is provided with a main body portion having a length capable of contacting both ends with the lower surface of the valley portion of the folding roof, and the folding plate roof provided at both ends of the main body portion. It is formed with a pair of bent pieces that can be brought into contact with and locked at the corners of the troughs, but the body part may not be able to contact the troughs if it is shorter than the dimension between the troughs of the folding plate roof . In addition, even if the length of the main body is sufficiently longer than the dimension between the valleys of the engraved roof, even if the end of the main body can contact the valley, the angle of the main body cannot be adjusted with respect to the inclination of the roof. In addition, only a part of the area at both ends is in close contact with the bottom of the valley, and a sufficient tightening force may not be applied by the nut.

  In addition, this contact plate is made by screwing a contact plate nut to the suspension bolt and moving it to the middle portion of the suspension bolt, and then inserting the suspension bolt into the fixing hole of the roof. The nut is tightened and attached to the lower surface of the valley section of the folding roof, but the movement of the nut and fixing of the contact plate are performed on a ladder with high space and a narrow space, so it is still dangerous work. . In addition, the larger the basket size, the larger the number of parts and the size of the parts, and the more difficult the work required for transportation and attachment becomes.

  On the other hand, Patent Document 2 is provided at the lower end of the support material having a height adjusting means that can be expanded and contracted while the upper end portion is attached downward to the eaves edge and attached to the mountain portion of the folding roof, There has been proposed an eaves rod suspension fitting including an eaves rod support member having an inner cross-sectional shape capable of holding at least one ear portion of the eaves rod. The height adjusting means includes, for example, a long hole provided in the longitudinal direction (vertical direction) at either the lower end of the upper support member or the upper end of the lower support member that is superposed on the lower end, and the long hole. It is formed by a set screw screwed into the inside from the outside.

  As a result, the load due to snow, wind pressure, etc. can be distributed to prevent bending at the middle part of the eaves, and the eaves can be attached to the overall structure without causing damage to the eaves. It is easy to manufacture, maintain, and inspect, and can provide eaves-hanging brackets that are low in production and construction costs.

  However, in Patent Document 2, the height adjusting means is formed by a set screw that is screwed into the elongated hole from the outside. After loosening the set screw, the set screw is slid in the elongated hole and moved upward. After adjusting the length of the lower support member so that it can expand and contract with respect to the support member, the eave ridge is attached to the eaves of the roof, and this length adjustment is difficult, so it is difficult to attach and the structure is not necessarily simple It was.

  Under such circumstances, there is a need for an eaves-hanging metal fitting that is easy to adjust in height and tilt and that has sufficient mounting strength when the eaves are attached to the eaves of the roof.

JP-A-8-158557 JP 2004-300716 A

  In view of the problems of the prior art, the object of the present invention is to easily adjust the vertical position of the eaves ridge support member when attaching the eave ridge support member to the folded roof. It is an object of the present invention to provide an eaves-hanging metal fitting that prevents the suspension bolt from being bent and the folded roof from being damaged when an external force or vibration such as wind and snow is applied to the eaves.

  As a result of intensive research to solve the above problems, the inventor has drawn the inner peripheral surface of the suspension bolt hole into a substantially spherical shape by the suspension bolt whose upper end is fixed to the mountain portion of the folding plate roof. Insert the presser plate that became a recess, the tip convex part is approximately spherical, fit with the recess, and fix the presser plate with a presser plate fixing nut with a screw that engages with the suspension bolt inside the center The eaves hanging bracket was configured as follows. Using this eaves hanging metal fitting, after receiving the tip convex part formed in the substantially spherical shape of the holding plate fixing nut into the hanging bolt hole of the holding plate that has been pulled out into a substantially spherical shape to form a recess, the holding plate When the plate fixing nut is tightened, the upper surface of the presser plate is in close contact with the lower surface of the valley of the folding roof, so that it does not take an unreasonable posture even in high places and narrow places on the ladder. Since it can be screwed and fixed relatively easily, the mounting operation can be performed safely and in a short time, and the eave ridge can be attached to the folded plate roof with sufficient strength.

That is, according to the present invention, there is an eave ridge support member that supports the eave ridge, and a suspension bolt that suspends the eave ridge support member, and the eave ridge on the folded plate roof in which peaks and valleys are alternately continuous. In the eaves hanging bracket for attaching the eaves rod, the suspension bolt penetrates into the central portion, and is attached above the eaves rod support member so that both ends abut against the valley portion, and the inner circumference of the suspension bolt hole A pressing plate fixed in which a surface is drawn out into a substantially spherical shape to form a recess, and a tip convex portion is approximately spherical, is fitted with the recess and has a screw that is screwed into the suspension bolt in the center. An eaves-hanging metal fitting characterized by having a nut is provided.
According to the second invention of the present invention, the opening diameter of the suspension bolt hole is larger than the outer diameters of the upper end nut and the mountain seat attached to the upper end of the suspension bolt, and the tip convex portion of the presser plate fixing nut An eaves-hanging metal fitting characterized in that it is smaller than the maximum outer diameter is provided. Further, according to the third invention of the present invention, the holding plate fixing nut is of a split type or an insertion type. An eaves hanging bracket is provided.

In the eaves-hanging metal fitting of the present invention, the inner surface of the holding plate having a suspension bolt hole in the center is pulled out into a substantially spherical shape to form a recess, and a holding plate fixing nut (hereinafter also referred to as a wing nut). Because it is slidable in a ball joint-like manner with the spherical surface of the tip convex part, the angle of the holding plate can be adjusted easily according to the inclination of the roof. Therefore, it can be easily rotated, screwed and fixed by grasping with the finger of the hand, and it is not necessary to use a spanner, and the installation work can be performed safely, easily and in a short time.
And, the opening diameter of the suspension bolt hole is larger than the outer diameter of the upper end nut and the pedestal attached to the upper end of the suspension bolt, and smaller than the maximum outer diameter of the tip convex portion of the pressing plate fixing nut, The pressing plate can be attached to and detached from the suspension bolt with an upper end nut or a pedestal attached, which facilitates packing and carrying. Further, by making the holding plate fixing nut into a split type or an insertion type, it is possible to retrofit the suspension bolt.
Moreover, even if the length of the pressing plate is shorter than the distance between the adjacent valley portions of the folding roof, it can be easily handled by stacking the length adjusting plate on the pressing plate.

  Furthermore, when a lateral external force is applied to the eaves fence, the suspension bolt is only subjected to bending stress with its middle part (the part to which the holding plate is attached) as a fulcrum. Stress is generated by being distributed between the peak part where the bolt is fixed and the bottom surface of the valley part where the pressing plate is in contact, and compared with the case where bending stress with the upper end part as a fulcrum is generated as in the prior art. Suspension bolts are extremely difficult to bend and the folding roof is not damaged.

It is.

Hereinafter, the eaves-hanging metal fitting of the present invention will be described in detail with reference to the drawings. The eaves-hanging metal fitting of the present invention has an eaves-holding support member that supports the eaves-holding member, and a suspension bolt that suspends the eaves-holding support member. An eaves hanging bracket for attaching the eaves, wherein the suspension bolt penetrates through the center portion, and is attached above the eaves eaves support member so that both ends abut against the valley portion, A pressing plate whose inner peripheral surface is drawn out into a substantially spherical shape to form a recess, and a pressing member in which a tip convex portion has a substantially spherical shape, is fitted with the recess, and has a screw that is screwed into the suspension bolt in the center. A plate fixing nut is provided.
The eaves-hanging metal fitting according to the present invention uses an eaves-hanging metal fitting (hereinafter also referred to as a first eaves-housing metal fitting) that uses a holding plate in which the periphery of the suspension bolt hole is raised depending on the shape of the hanging bolt hole of the holding plate. And an eaves-hanging bracket (hereinafter, also referred to as a second eaves-hanging bracket) using a flat holding plate having a flat periphery of the suspension bolt hole.

  The folding plate roof to which the present invention is applied uses a metal plate or a plastic plate in which a mountain part and a valley part have a W-shaped continuous cross section, and is cheaper than a tile roof, a slate roof or the like. Because of its light weight and easy installation work, it is widely adopted as buildings for factories, warehouses, cattle barns, poultry farms, parking lots, road stations, vegetable stores, sports facilities, and simple houses. And, on this folding roof, the trap that catches the rainwater coming down the valley is attached to the lower part of the eaves and parallel to the eaves. When exposed, it slips back and forth and easily breaks.

  As shown in FIG. 1, the eaves-hanging metal fitting of the present invention has a suspension bolt 1 whose upper end is fixed to the peak portion of the folding plate roof, and both ends abutting against the valley portion of the folding plate roof that is inserted into the suspension bolt. A pressing plate 10 to be pressed, a pressing plate fixing nut 4 (wing nut) in which a convex portion at the front end is fitted into a concave portion (inner peripheral surface of the suspension bolt hole) of the pressing plate 10 and screwed, and an eaves rod support member 11 It is the structure containing. The holding plate 10 receives the convex portion of the tip of the wing nut 4 in the concave portion, and tightens the wing nut 4 so that the curved upper surface is parallel to the bottom surface of the folding roof and both ends are folded. It is in close contact with the bottom surface of the valley of the plate roof and press-contacted.

  In the present invention, the suspension bolt 1 is a member that joins the mountain portion of the folded roof and the central portion of the eaves supporting member 11 formed in a shape capable of supporting the eaves. The material of the suspension bolt 1 is preferably a strong steel material, particularly a stainless steel material resistant to rust. The diameter of the suspension bolt 1 depends on the size and material of the eaves but is about 1 to 5 cm.

  The suspension bolt 1 having a dimension longer than the vertical distance from the upper surface of the ridge 7 to the lower surface of the valley 8 is used. Further, an upper end upper nut 20, a mountain seat (and felt, flat seat) 21, an upper end lower nut 201, a holding plate 10, a wing nut 4, and a lower end nut 2 are attached to the suspension bolt 1.

  Of the nuts constituting the eaves hanging bracket, ordinary metal nuts are used for the upper end upper nut 20, upper end lower nut 201, and lower end nut 2, and plastic nuts resistant to rust may be used. The wing nut 4 is preferably a metal nut whose upper part is covered with a plastic resin or a fusible metal. A stabilizer, a colorant, etc. can be mix | blended with resin. Examples of the material plastic include polyethylene, polypropylene, polystyrene, polyamide, polycarbonate, polyester, and engineering plastic. Examples of the fusible metal include tin, zinc, lead, and alloys thereof.

  Next, the pressing plate 10 that is a feature of the present invention will be described. As shown in FIG. 2, the holding plate 10 is inserted into an intermediate portion of the suspension bolt 1 (above the eaves supporting member), and its both ends are in contact with the lower surface of the valley portion of the folding roof. It is a reinforcing plate. A hole through which the suspension bolt 1 passes is formed in the center of the press plate 10.

  The length of the pressing plate 10 is at least necessary to cover the ends of both valley portions of the adjacent folded plate roof, but may be longer than that. If the plate is long, a sufficient contact area with the valley portion of the folding roof can be secured, so that external force (wind and snow force) can be dispersed and the eaves supporting member can be prevented from falling and the eaves from shaking. The length of the pressing plate 10 is, for example, about 20 to 80 cm, and particularly preferably about 30 to 50 cm.

  Although the width | variety of the pressing board 10 is related with the contact state with the trough part of a folding plate roof, it is 5-20 cm, for example, Preferably you may be about 8-15 cm. If it is in this range, the contact area with the valley can be secured, so external force (wind and snow force) can be dispersed and absorbed, and it is almost the same as the width of the rain gutter, so it is not too heavy and installation on the roof does not become inconvenient. Because.

  The material of the pressing plate 10 is plastic or metal. As the plastic, resins such as vinyl chloride, polyethylene, polypropylene, polystyrene, polyamide, polycarbonate, polyester, and engineering plastic are used. You may mix | blend fillers, such as a stabilizer and a coloring agent, glass fiber, glass powder, and wollastonite, with resin. Examples of the metal include iron, aluminum, titanium, and stainless steel. Further, wood or bamboo material may be used if it has sufficient strength and durability. Moreover, since the function of the pressing plate 10 is mainly to prevent the suspension bolt 1 from swinging, waste materials and by-product materials may be effectively used as long as this purpose is not impaired. The pressing plate 10 may be a single layer as shown in the figure or may be a laminated structure.

The pressing plate 10 has a relatively thin thickness of 1 to 3 cm, preferably 1 to 2 cm, and warps upward from the center to the left and right ends. If it is the thickness of this range, the front-end | tip part of the wing nut 4 can be received in a suspension bolt hole, maintaining intensity | strength.
The degree of warping of the pressing plate 10 is preferably an arc of R100 to R500 cm, particularly an arc of R250 to R350 cm. If the presser plate 10 is warped in this way, it will become horizontal when a load is applied to the left and right ends of the presser plate 10 to generate a repulsive force, and the bottom surface of the valley of the folded plate roof and the presser plate are pressed against each other. Even if the rocking force of the left, right, front, back, and top and bottom from the eaves propagates to the retainer plate, the retainer plate and the valley of the folding plate roof are not separated, and the effect of preventing or dispersing the eaves is produced. A flat plate can also be used, but by making it curved in this way, there is also an advantage that the degree of load application is easy to understand because it gradually becomes horizontal when a load is applied to the left and right ends from below.

  Moreover, it is preferable to stick the adhesive tape 101 to the part which contact | abuts the lower surface 8 of the trough part of a folding plate roof at the both ends of the press board 10. FIG. If the bottom surface 8 of the valley portion of the folded plate roof and the holding plate 10 are bonded, the holding plate and the valley portion of the folded plate roof are separated even if the left / right, front / rear, up / down swinging force from the eaves is propagated to the holding plate 10. This is because it can be prevented. For this reason, the adhesive tape 101 is preferably a double-sided adhesive tape.

Although the shape of the pressing plate 10 in the present invention is not particularly limited, the first eaves-hanging metal fitting is provided with the protruding portion 3 that is raised around the suspension bolt hole.
In FIG. 2, the projecting portion 3 is shown as a heel-down, and accepts the tip convex portion of the wing nut 4 inserted into the concave portion of the pressing plate 10 to form a joint. The inner peripheral surface of the suspension bolt hole of the projecting portion 3 is mortar-shaped, and its upper hole diameter is 1.5 to 2.5 times the suspension bolt diameter so that the holding plate 10 can be tilted, and the lower hole diameter is The diameter is preferably 1.1 to 1.4 times the suspension bolt diameter.

  By making the suspension bolt hole inside the protruding portion 3 into a mortar shape, the pressing plate 10 can be appropriately inclined and easily adjusted to the inclination angle of the roof, and the pressing plate is not damaged by the suspension bolt. In FIG. 2A, the pressing plate 10 is inclined 5 ° so as to match the inclination angle of the roof, and in FIG. 2B, the pressing plate 10 is inclined 11 ° because the inclination angle of the roof is large.

  As described above, the pressing plate 10 and the protruding portion 3 may be integrally formed of the same material, but a part having the same shape as the protruding portion may be separately created and embedded in the pressing plate.

  Moreover, although the position of the suspension bolt hole is positioned at the center of the pressing plate 10 in the left-right direction, it is not always necessary to be positioned at the center of the pressing plate 10 in the front-rear direction. By slightly shifting the position of the suspension bolt hole in the front-rear direction, it is possible to prevent the rainwater that has been transmitted from the tip of the folding roof from the suspension bolt 1 from flowing onto the holding plate 10.

In the present invention, the presser plate fixing nut (wing nut) 4 has its tip convex part fitted into the concave part (suspension bolt hole) of the presser plate 10, and the presser plate 10 is pushed up by tightening the presser plate fixing nut 4. Is a member for contacting the lower surface 8 of the valley portion of the folding roof.
In the first eaves-hanging metal fitting, as shown in FIG. 2, the holding plate fixing nut 4 has plastic placed on a metal nut 5 that is screwed to the suspension bolt, the upper end is hemispherical, the body is cylindrical, and the lower portion is It is shaped to have a butterfly wing shape. The reason why the lower part has a butterfly wing shape is that it can be gripped by hand and can be easily rotated, and the screwing operation can be performed safely and in a short time even at a high place of the eaves.

  The upper part of the wing nut 4 has a hemispherical tip, and has a predetermined length. Therefore, when the wing nut 4 comes into contact with the inner peripheral surface of the protrusion 3 of the pressing plate 10, it is pressed like a ball joint. Can connect boards. The upper inner surface of the protruding portion 3 has a mortar shape, but the inclination angle of the pressing plate 10 can be changed depending on its diameter. The inclination angle corresponds to the inclination of the roof and is usually in the range of 5 to 15 °. If the roof is slanted, for example, as shown in FIG. 2A, the holding plate 10 is inclined 5 ° with respect to the bottom surface of the wing nut 4, and if the roof is large, the holding plate 10 is 11 as shown in (B). ° Inclined. The shape of the tip is preferably substantially spherical (hemispheric), but is not limited as long as the inclination angle can be within this range.

The lower part (body) of the wing nut 4 is cylindrical, and the cylindrical part is a part connecting the hemisphere at the tip and the lower butterfly wing part. This portion is not limited to a cylindrical shape, and may be, for example, a polygonal column such as a quadrangular column, a pentagonal column, or a hexagonal column. It is a necessary condition that the diameter of the cylindrical portion is smaller than the inner diameter of the projecting portion 3 of the pressing plate 10 and larger than the diameter of the suspension bolt 1. If the diameter of the suspension bolt 1 is about 1 to 2 cm, About 5 to 3 cm is preferable.
In the present invention, the holding plate fixing nut may be a donut shape as described above, but may be a split type or an insertion type. As shown in FIG. 6, each of the split-type holding plate fixing nut and the insertion-type holding plate fixing nut has a structure in which a suspension bolt is sandwiched from the left and right by forming a female screw 43, and the split-type nut (A) is The right-hand member 4a and the left-hand member 4b that are symmetrical to each other, and the plug-in nut (B), are obtained by connecting the right-hand member 4a and the left-hand member 4b with a hinge 42 at the end. Any of the parts can be formed entirely of plastic or a fusible metal.

  In the present invention, the eaves rod support member (bracket) is attached to the lower end of the suspension bolt 1 and formed in a shape capable of supporting the eaves rod as shown in FIG. Further, the lower nuts 22 and 23 are used to connect the eaves supporting member 11 at the lower end of the suspension bolt 1 and connect the eaves. As long as the eaves rod support member 11 has a function of joining the eaves rod 12 and the lower end of the suspension bolt 1, any shape may be used. FIG. 3B shows a state where the eaves rod support member 11 is coupled to the lower nuts 22 and 23 at the lower end of the suspension bolt 1 and the eaves rod 12 is connected.

The second eaves-hanging metal fitting of the present invention uses a flat pressing plate having no protrusion around the suspension bolt hole. After the pressing plate is inserted into the hanging bolt, the tip of the pressing plate fixing nut (Middle abdomen).
In the second eaves-hanging metal fitting, the opening diameter of the suspension bolt hole of the retainer plate is larger than the outer diameters of the upper end nut and the mountain seat attached to the upper end of the suspension bolt, and the maximum protrusion of the distal end convex portion of the retainer plate fixing nut Desirably smaller than the outer diameter. The opening diameter of the suspension bolt hole is preferably 1 to 5 mm larger than the outer diameter of the upper end nut (mountain seat). As a result, the holding plate can be freely attached to and detached from the suspension bolt, and packing and carrying become easy.

  In the second eaves-hanging metal fitting, it is preferable that the holding plate fixing nut is a split type or an insertion type. 5B and 5C, the side surface of the body portion of the pressing plate fixing nut 4 is formed into a substantially spherical surface, and the top portion 41 is formed into a polygonal column shape such as a quadrangular column, a pentagonal column, or a hexagonal column. The reason why the side surface of the body portion is formed into a substantially spherical surface is to bring the presser plate 10 into contact with the inner peripheral surface of the presser plate 10 like a ball joint and to connect the presser plate 10 along the bottom slope of the folding plate roof. Moreover, the top 41 is formed in a polygonal column shape such as a hexagonal column because the suspension bolt hole of the pressing plate 10 does not damage the suspension bolt hole even if it directly contacts the suspension bolt. If the top 41 is a hexagonal column, it can be tightened with a spanner. However, since the lower part of the presser plate fixing nut 4 has a butterfly wing shape, it can be grasped by hand and easily rotated, so that the screwing operation can be performed safely and in a short time even at the high place of the eaves.

As shown in FIGS. 6A and 6B, in the second eaves-hanging metal fitting, the holding plate fixing nut 4 is a split type or a plug-in type constituted by a right side member 4a and a left side member 4b. . When the right side member 4a and the left side member 4b of the nut 4 are combined with the suspension bolt and the pressing plate 10 is placed from the upper part thereof, the middle part of the split-type nut (4A) is sandwiched between the pressing plates. The left side member 4b is not separated. On the other hand, in the case of the plug-in nut (4B), since the right member 4a and the left member 4b are joined by the hinge 42 at one end, the uniting to the suspension bolt is easier.
With such a structure, the holding plate fixing nut can be freely attached to and detached from the suspension bolt, and packing and carrying are facilitated. Moreover, since the nut 4 can be retrofitted at a position close to the holding plate inserted into the long suspension bolt, the time required for tightening can be shortened. However, the presser plate fixing nut 4 in the second eaves hanger is not limited to this, and the donut-shaped wing nut described in the first eaves hanger can also be used.

The holding plate in the second eaves-hanging bracket is usually made of plastic, and the holding plate fixing nut can also be made of plastic. It can be packed separately from other metal parts such as a support member (bracket).
Moreover, when attaching a pressing plate to a folding roof, it can be easily assembled as an eaves-hanging metal fitting of the present invention on the site without removing a metal nut or a mountain seat from a suspension bolt. That is, if the holding plate fixing nut is a split-type nut, as shown in FIG. 6 (A), first, the holding plate 10 is inserted into the suspension bolt 1 and then the right side of the split-type nut (4A) below it. The member 4a and the left member 4b are integrated close to each other from the left-right direction. If the holding plate fixing nut is an insertion type nut, as shown in FIG. 6 (B), first, the holding plate 10 is inserted into the suspension bolt 1, and then the right side of the insertion type nut (4B) below it. The ends of the member 4a and the left member 4b are opened, and the suspension bolt 1 is sandwiched and integrated. Then, turn the butterfly wing part of the nut (4A, 4B) by hand, or turn the polygonal column part 41 at the top with a spanner to push up the holding plate toward the folding roof, Press contact to the bottom.
In addition, since a split-type nut or a plug-in nut is used, it can be safely and quickly attached to a folding roof even for large eaves, but once installed, the position of the holding plate on the suspension bolt is corrected. Needless to say, the work can be facilitated even in the case of replacement or replacement.

  Next, although the eaves hook suspension metal fitting of this invention and the method of attaching an eave fence to a folding roof using it are demonstrated more concretely, this invention is not limited to this Example.

Example 1
In order to produce the eaves-hanging metal fitting of the present invention, a stainless steel bolt having a diameter of 1.5 cm having sufficient strength and corrosion resistance was prepared for the hanging bolt. This was selected to have a length of 30 cm, which is longer than the vertical distance from the upper surface of the mountain portion of the folding roof to the lower surface of the valley portion.
Further, as shown in FIGS. 2 and 4, the presser plate was formed of polypropylene so that the length of the plate was 34 cm, the width was 6 cm, the thickness was 1 cm, and the warp of the plate was an arc of R300 cm. The presser plate 10 was integrally formed with a protrusion 3 having a mortar-shaped hole having a height of 2 cm and a suspension bolt hole having an upper inner diameter of 2.5 cm and a lower inner diameter of 2 cm. And the 5 cm x 5 cm double-sided adhesive tape 101 was affixed on the part which contact | abuts the lower surface of the trough part of a folding plate roof at the edge part of the press plate.
The holding plate fixing nut 4 has a hemispherical tip, a lower part of which is a cylinder with an outer diameter of 2.3 cm and a length of 1 cm, and a metal nut 5 with an outer diameter of 2.5 cm is embedded in polypropylene at the lowermost part thereof. The lower outer periphery was formed into a butterfly wing shape.

  Using the eaves hanging hardware comprised of these members, it was attached to the folded roof as follows. First, as shown in FIG. 4, in order to attach the upper end of the suspension bolt 1 to the peak portion 7 of the folding plate roof, a hole (not shown) is made in the peak portion 7 of the folding plate roof, and then the upper end of the suspension bolt 1. Is passed through the hole of the ridge 7 of the folding roof from below, the nut 20 and the pedestal 21 (outer diameter 2 cm) are attached, and the upper end lower nut 201 is screwed together so that the pair of nuts 20 and pedestal 21 And 201 sandwiched the mountain part 7 of the folding roof.

Next, the holding plate 10 was inserted into the suspension bolt 1 with the protruding portion 3 facing upward, the wing nut 4 was screwed, and the holding plate 10 was moved to the vicinity of the middle portion of the hanging bolt 1. The holding plate 10 and the wing nut 4 may be inserted into the suspension bolt 1 in advance before the upper end of the suspension bolt 1 is passed through the hole of the mountain portion 7 of the folding plate roof from below. Then, while turning the wing nut 4 by hand, the upper surface of the pressing plate 10 is brought close to the roof valley 8 to adjust the height, and the double-sided adhesive tape 101 at both ends of the pressing plate 10 is peeled off to remove the roof valley 8. It was made to contact the lower surface. As the wing nut 4 was tightened, the holding plate 10 whose end was warped upward became horizontal and was crimped to the trough 8 of the roof.
Finally, the ear 121 of the eaves 12 is locked to the pair of locking pieces 122 of the eaves support member 11 to support the eaves 12.

  Similarly, the eaves ridge was attached to the folding plate roof at a position 80 cm away from the attachment position of the reinforcement using another set of eaves hangers having the pressing plate 10. And in the eaves rod, a 3kg weight of timber was put on the snow, and pulled from the front of the eave cage horizontally with a force of 20kg for 1 minute. This means that a stress of 10 kg was applied per reinforcement, but the position of the eaves was hardly changed after the test.

(Example 2)
As shown in FIG. 5, the pressing plate was a flat polypropylene plate, and the suspension bolt hole had an upper inner diameter of 2.3 cm and a lower portion having a hemispherical shape with an inner diameter of 2.5 cm. The presser plate fixing nut 4 is a split type with a hexagonal column (nut shape) with an outer diameter of 2.0 cm at the tip, a hemispherical shape with an intermediate portion of 2.8 cm in diameter, and a lowermost outer periphery in a butterfly shape. Molded into nuts. Other than that was carried out similarly to Example 1, and produced the eaves-hanging metal fitting of this invention.
That is, the pressing plate 10 is 34 cm long, 6 cm wide and 1 cm thick, and is shaped so that the warping of the plate is an arc of R300 cm, and the bottom surface of the valley of the folded plate roof at the end of the pressing plate 10 A 5 cm × 5 cm double-sided pressure-sensitive adhesive tape 101 was attached to the part that abuts on.

Using the eaves hanging hardware comprised of these members, it was attached to the folded roof as follows. First, as in Example 1, the upper end of the suspension bolt 1 was attached to the mountain portion 7 of the folded plate roof as shown in FIG.
Next, as shown in FIG. 6A, the right-side member 4a and the left-side member 4b of the split-type nut (4A) are sandwiched from the left and right directions with the suspension bolt 1 below the presser plate 10 and integrated. Thereafter, the holding plate 10 was placed on the split-type nut (4A), and the middle part of the split-type nut (4A) was sandwiched between the suspension bolt holes. Subsequently, while turning the butterfly-shaped portion of the split-type nut (4A) by hand, the upper surface of the pressing plate 10 is brought close to the valley 8 of the roof to adjust the height, and the double-sided adhesive tape 101 at both ends of the pressing plate 10 is adjusted. Was peeled off and brought into contact with the lower surface of the valley 8 of the roof. As the wing nut 4 was tightened, the holding plate whose end was warped upward became horizontal and was crimped to the trough 8 of the roof.
Finally, the ear 121 of the eaves 12 is locked to the pair of locking pieces 122 of the eaves support member 11 to support the eaves 12. As in Example 1, the eaves can be safely and stably attached to the folding roof.

(Example 3)
As the holding plate fixing nut 4, instead of the split-type nut of the second embodiment, a plug-type nut in which the right member 4a and the left member 4b are joined by a hinge at one end is used in the same manner as in the first embodiment. An eaves-hanging metal fitting of the invention was produced. This plug-in nut has a hexagonal column (nut shape) with an outer diameter of 2.0 cm at the tip, a hemisphere with a diameter of 2.8 cm in the middle, and a lowermost outer periphery in a butterfly shape.
Next, as shown in FIG. 6 (B), the right side member 4a and the left side member 4b of the plug-in nut (4B) are widely opened to the left and right to the suspension bolt 1 below the holding plate 10 and integrated. . Thereafter, the pressing plate 10 was placed on the insertion nut (4B), and the middle part of the insertion type nut (4B) was sandwiched between the suspension bolt holes. Subsequently, while turning the butterfly portion of the plug-in nut (4B) by hand, the height of the pressing plate 10 is adjusted by bringing the upper surface of the pressing plate 10 close to the trough 8 of the roof, and the double-sided adhesive tape 101 at both ends of the pressing plate 10 is adjusted. Was peeled off and brought into contact with the lower surface of the valley 8 of the roof. As the wing nut 4 was tightened, the holding plate whose end was warped upward became horizontal and was crimped to the trough 8 of the roof.
Finally, the ear 121 of the eaves 12 is locked to the pair of locking pieces 122 of the eaves support member 11 to support the eaves 12. As in Example 1, the eaves can be safely and stably attached to the folding roof, and the operation is easier than in Example 2.

(Comparative Example 1)
Compared to the first embodiment, two sets of conventional hanging metal fittings made only of suspension bolts and metal nuts are used instead of the eaves hanging metal fittings having the holding plate and the butterfly nut, and the eaves eaves are spaced at 80 cm intervals on the folding roof. An eaves was attached via a support member. And in the eaves rods, 3 kg of square timber weighted from snow was placed and pulled horizontally from the front of the eaves rods with a load of 20 kg for 1 minute. This means that 10 kg of stress was applied per reinforcing tool, but after the test, the position of the front ear part of the eaves was moved 3 cm toward the front and 5 cm upward.

According to this comparison experiment, in the prior art (Comparative Example 1), bending stress with the upper end portion as a fulcrum is generated in the suspension bolt 1, so that the bending position and the mounting position are shifted. If the eaves rod 12 is attached to the folding roof using Example 1), when a lateral external force is applied to the eaves rod 12, the suspension bolt 1 has an intermediate portion (a portion where the pressing plate 10 is attached). ) Is only generated as a fulcrum, and the folding roof has a stress distributed and distributed between the peak portion 7 to which the suspension bolt 1 is fixed and the lower surface of the valley portion 8 to which the pressing plate 10 abuts. Since it occurs, it can be seen that it is not very flexible and the folded roof is much less likely to be damaged.
Moreover, if the eaves-hanging metal fittings (Examples 2 and 3) of the present invention are used, the holding plate can be freely attached to and detached from the hanging bolt, so that the parts can be easily packed and transported. Since the split-type nut or the plug-in nut that can be easily attached to the bolt is used, it can be seen that a large eaves can be safely and quickly attached to the folded roof.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change or the like without departing from the gist of the present invention. included.
