Description

The present invention relates to a roof structure and a method of installing a cover.

BACKGROUND ART Techniques for building structures such as wooden frameworks, wooden frameworks, reinforced concrete structures, RC structures, etc., are known as buildings used for houses and the like. Also, for such a building, a roof structure formed by a roof having a flat roof surface is known as a roof shape. As such a roof structure, for example, a technique is known in which a plurality of plate-like roof materials are tied to sheathing boards with tie nails (see, for example, Patent Document 1).

The above-described roofing material deteriorates in appearance due to deterioration over time. For example, there is known a technique for improving the appearance of a roof by covering the roof material with a decorative cover that improves the appearance. Such a cover has a top plate, side plates, and bottom plate for covering the top surface, end surfaces, and bottom surface of the roof material. One method of attaching the cover to the roofing material is to apply an adhesive to the surface of the roofing material before the cover is installed. The surface of the roofing material to which the cover is to be attached is often contaminated, and it is necessary to wash the surface of the roofing material as a pretreatment. For this reason, the work of attaching the cover to a large number of roofing materials is complicated, so a technique for easily and firmly joining the roofing materials is desired.

The roof structure 1 includes sheathing boards 110, underlaying materials 120, a plurality of roofing materials 130, a plurality of binding nails 140, a plurality of covers 150, joints 160, eaves edge drains 170, and verge drains 180. , an end cover 200, a ridge cover 220 and a coping. 1 to 3, the underlaying material 120 is omitted.

In addition, the roof structure 1 may have other members such as heat shield sheets and ventilation members between the sheathing board 110 and the roof material 130 .

The sheathing board 110 is fastened to the rafters with nails or the like. The sheathing board 110 is made of structural plywood, for example. The sheathing board 110 may be an MDF (Medium Density Fiberboard), a particle board, an OSB (Oriented Strand Board), or a single plate material such as cedar bark.

The underlaying material 120 is a so-called roofing sheet having waterproof properties. For example, the underlayment 120 is formed by impregnating and/or coating a substrate with asphalt. The underlaying material 120 is fastened to the sheathing board 110, for example. As a specific example, the underlaying material 120 is provided on the front board of the sheathing board 110 .

The plurality of roof materials 130 are arranged in a first direction (longitudinal direction), which is the inclination direction (longitudinal direction) of the sheathing board 110 from the ridge 11 toward the eaves 12, and a second direction (horizontal direction), which is a width direction (horizontal direction) perpendicular to or crossing the first direction. , and are arranged in multiple columns, respectively. For example, joints 160 are arranged between roofing materials 130 that are adjacent in the second direction. In addition, depending on the part, it may not be inclined.

A plurality of roofing materials 130 are partly laminated in the direction of inclination (first direction) from the ridge 11 toward the eaves 12, and are tied by binding nails 140 on the sheathing board 110 to which the underlaying material 120 is fastened. be.

The roof material 130 is formed in a plate shape. The roof material 130 has, for example, a plurality of pilot holes 131 on the central side in the direction of inclination of the sheathing board 110 in a direction orthogonal to the direction of inclination. The pilot hole 131 is formed to have a smaller outer diameter than the head portion 141 of the binding nail 140 and a larger diameter than the nail portion 142 of the binding nail 140 . That is, the pilot hole 131 is an opening through which the nail portion 142 of the binding nail 140 is inserted.

The tie nail 140 is used in the roof structure 1, for example, to tie the roofing material 130 to the sheathing board 110, as shown in FIG.

The binding nail 140 is driven into the sheathing board 110, for example, in the thickness direction of the sheathing board 110, in other words, in a direction orthogonal to the plane direction of the main surface of the sheathing board 110. The driving direction of the binding nail 140 is not limited to the thickness direction of the sheathing board 110 .

The tie nail 140 includes, for example, a head portion 141 and a nail portion 142 .

Head 141 is formed in a disc shape.

The nail portion 142 is integrally formed on one main surface of the head portion 141 . The nail portion 142 is formed in a cylindrical shape. Further, the nail portion 142 has, for example, a plurality of ring-shaped protrusions 142a formed at equal intervals in the axial direction (longitudinal direction) of the nail portion 142 .

The plurality of projections 142a improve the binding force for binding the roofing material 130 to the sheathing board 110 when the binding nails 140 are driven into the sheathing board 110. - 特許庁In other words, the plurality of protrusions 142a improve the tensile strength, which is the holding force in the direction in which the binding nail 140 is removed from the sheathing board 110 when it is nailed to the sheathing board 110 . The plurality of projections 142a are provided at least in a portion arranged inside the roofing board 110, for example, so that the binding force between the roofing board 110 and the roofing material 130 can be improved. The number and shape of the projections 142a can be appropriately set as long as the binding force can be improved.

The cover 150 covers one or a plurality of roof materials 130 among the plurality of roof materials 130 arranged in parallel in the width direction at the same height position. For example, the cover 150 is a decorative cover that covers the roof material 130 to improve the appearance when the appearance of the roof material 130 deteriorates due to aging deterioration or the like. In this embodiment, the cover 150 does not cover the roofing material 130 positioned at the eaves edge 12, and the end cover 200 covers the roofing material 130 positioned at the eaves edge 12 as shown in FIG.

The cover 150 includes a top plate 151 , side plates 152 and a bottom plate 153 . The cover 150 has a top plate 151, side plates 152, and a bottom plate 153 integrally formed by bending a steel plate, for example. Further, the cover 150 has a plurality of rectangular drainage holes 154 formed on the ridge between the side plate 152 and the bottom plate 153 or on the bottom plate 153 side of the side plate 152 . The cover 150 has water resistance and weather resistance, and is painted or the like in order to obtain a beautiful appearance. The cover 150 is adhered to the roofing material(s) 130 by an adhesive, for example. Note that the covers 150 adjacent to each other in the vertical direction may be adhered to each other with an adhesive.

The top plate 151 covers at least the area exposed to the outside of the upper surface of the roofing material 130 . The width dimension of the top plate 151 is set larger than the width dimension of one roof material 130 . Also, the depth dimension of the top plate 151 is set to be the same as or slightly smaller than the depth dimension of one roof material 130 . Specifically, the depth dimension of the top plate 151 is the depth of the top plate 151 when the cover 150 is arranged on the lower roof material 130 among the roof materials 130 stacked in the tilt direction from the ridge 11 toward the eaves 12 . The length can be appropriately set as long as the end portion of the ridge side is covered with the upper roof material 130 . Here, the depth means the direction of the roof structure 1 on the under water (edge of the eaves 12) side and above the water (ridge 11) side.

The side plate 152 continues integrally with the top plate 151 and the bottom plate 153 . The side plate 152 covers the side surface of the roof material 130 on the side of the eaves 12 . The width dimension of the side plate 152 is set to the same dimension as the width dimension of the top plate 151, for example. The side plate 152 is arranged on the eaves 12 side of the top plate 151 . The side plate 152 is inclined at an acute angle, for example, 45°, with respect to a surface along the planar direction of the top plate 151 and a direction orthogonal to the top plate 151 so that the bottom plate 153 side is closer to the eaves 12 side than the top plate 151 side. .

In other words, the side plate 152 is inclined at an obtuse angle, for example, 135°, with respect to the lower surface of the top plate 151 (main surface inside the cover 150). Here, the surface along the surface direction of the top plate 151 is a virtual plane F extending along the surface direction of the top plate 151 from the end of the top plate 151 on the side plate 152 side, as shown in FIG. is.

The bottom plate 153 is set parallel or substantially parallel to the top plate 151 . Therefore, the inclination angle of the side plate 152 with respect to the bottom plate 153 is set to an acute angle, for example, 45°. The bottom plate 153 covers at least the lower surface of the roof material 130 on the eaves 12 side. In addition, the space between the top plate 151 and the bottom plate 153 is set so that the roof material 130 can be arranged. The width dimension of the bottom plate 153 is set to the same dimension as the width dimension of the top plate 151 . The depth dimension of the bottom plate 153 is set shorter than the depth dimension of the top plate 151 . More specifically, the depth dimension of the bottom plate 153 is set to a dimension that is closer to the eaves than the ridge-side end of the top plate 151 of the cover 150 attached to the roof material 130 below. The bottom plate 153 may have a folded portion formed by folding back the plate material at the edge portion 153a on the side opposite to the side plate 152 to form a double structure.

The drain holes 154 are provided at a plurality of locations in the width direction of the cover 150 . The drain hole 154 is a drain hole for draining water that has entered the cover 150 .

A plurality of covers 150 are arranged adjacent to each other while partially overlapping each other in the vertical direction. By way of example, each cover 150 is sized and shaped to be larger than the width of a plurality of laterally aligned roofing materials. In the example shown in FIGS. 1 and 2, one cover 150 is attached to, for example, three roof materials 130 arranged in the width direction. The cover 150 includes a roofing material 130 to which the top plate 151 is attached, and a bottom plate 153 of the cover 150 attached to the roofing material 130 adjacent to the ridge side of the roofing material 130 and partially stacked. It is inserted between and assembled and fixed by the adhesive layer 155 .

In the pair of covers 150 arranged in the vertical direction, the edge 153a of the bottom plate 153 of the eaves-side cover 150 is positioned in the middle of the surface of the top plate 151 of the ridge-side cover 150 . Further, the edge 151a of the top plate 151 of the cover 150 on the ridge side is arranged at a position shifted by a predetermined distance toward the ridge from the edge portion 153a of the bottom plate 153 of the cover 150 on the eaves side. The edge 151a of the top plate 151 of the ridge-side cover 150 and the edge 153a of the bottom plate 153 of the eave-side cover 150 are arranged side by side within the range of the bonding region, which is the region where the bonding layer 155 spreads, for example. be.

The adhesive layer 155 is formed by curing an adhesive. For example, the adhesive layer 155 spreads along gaps between the cover 150 and the roofing material 130 when the adhesive is supplied between the covers 150 that partially overlap each other. It is formed in the area according to the For example, the adhesive layer 155 is arranged in such an amount and position that it does not protrude downward from the side edge 153 of the upper cover 150 . As an example, it spreads over a region of several cm in each of the width direction and the inclination direction. For example, adhesive layer 155 extends in a circular or oval shape.

The adhesive layer 155 is arranged on the edge portion 153 a of the bottom plate 153 closest to the ridge. Specifically, the adhesive layer 155 is arranged between the edge portion 153a of the bottom plate 153 and the surface portion near the edge 151a of the top plate 151 of the other cover 150 inserted behind the bottom plate 153, The top plate 151 and the bottom plate 153 are joined together. The adhesive layer 155 is arranged around the edge portion 153a of the bottom plate 153 from the front side to the back side. Further, the adhesive layer 155 is arranged from the edge 151 a of the top plate 151 to the back side of the top plate 151 and adheres to the surface of the roof material 130 . Therefore, the adhesive layer 155 is composed of the pair of covers 150 arranged in the vertical direction, the roof material 130 facing the front surface and the back surface of the bottom plate 153 of the cover 150 on the ridge side, and the cover 150 on the eaves side. The front surface of the top plate 151, the edge 151a, the back surface, and the roofing material 130 arranged to face the back surface are joined.

Joints 160 are provided between covers 150 adjacent in the width direction. The joint 160 is arranged above the roofing material 130 and below the cover 150 . The joint 160 is formed, for example, along the surface of the cover 150 and includes a top plate and side plates. The top plate faces the end of the top plate 151 of the cover 150 adjacent in the width direction. The side plates face the ends of the side plates 152 of the adjacent covers 150 .

The dimension of the side plate in the direction orthogonal to the width direction is set smaller than the same dimension of the side plate 152 of the cover 150 . Preferably, the side plate is sized so as not to overlap the drain hole 154 of the cover 150 in the direction of inclination from the ridge 11 toward the eaves 12 .

The joint 160 is set, for example, so that the angle of the side plate with respect to the top plate is different from the angle of the side plate 152 with respect to the top plate 151 of the cover 150 . In this embodiment, when the angle of the side plate 152 with respect to the top plate 151 of the cover 150 is 135° (the angle of the side plate 152 with respect to the virtual plane F along the surface direction of the top plate 151 is 45°), for example, The angle of the side plate with respect to the top plate is set at 90°.

The eaves edge drain 170 is provided, for example, along the width direction (second direction) of the eaves edge 12 . The eaves edge drain 170 has, for example, a base 171 arranged between the sheathing board 110 and the underlaying material 120 at the eaves edge 12, and a drain board 172 hanging downward from the end of the base 171 on the eaves edge 12 side. The drain board 172 has a return part on the side of the sheathing board 110 at the lower end.

A bristle drainer 180 is positioned, for example, on each bristle 13 . The karaba drainer 180 is tied to the sheathing board 110 via, for example, a coping. The brisket drainer 180 has a brisket plate depending downwardly from the brisket 13 .

As shown in FIG. 4, the end cover 200 covers the roofing material 130 located at the eaves 12 . For example, as shown in FIG. 4 , since two roofing materials 130 are stacked at the eaves edge 12 , the end cover 200 covers the two roofing materials 130 . Moreover, the end cover 200 covers one set or a plurality of sets of the stacked roofing materials 130 among the multiple stacked roofing materials 130 arranged in the width direction at the eaves edge 12 .

For example, the end cover 200 is a decorative cover that covers the roof material 130 to improve its appearance when the appearance of the roof material 130 deteriorates due to aging deterioration or the like. As shown in FIG. 4 , the end cover 200 includes a top plate 201 , side plates 202 and a bottom plate 203 . The end cover 200 is formed integrally with the top plate 151, the side plates 202, and the bottom plate 203 by bending a steel plate, for example. Also, the end cover 200 may have one or a plurality of rectangular drainage holes formed on the ridge between the side plate 202 and the bottom plate 203 or on the side plate 202 on the side of the bottom plate 203 . The end cover 200 has water resistance and weather resistance, and is painted or the like in order to obtain a beautiful appearance. The end cover 200 is adhered to the roofing material(s) 130 by an adhesive, for example. Note that the cover 150 and the end cover 200 that are vertically adjacent to each other may be bonded with an adhesive.

The ridge wrap 220 is provided on the ridge 11 . The ridge cover 220 covers, for example, the ridge 11 and the ends of the roofing materials 130 arranged on the ridge 11 on the ridge 11 side. For example, the ridge cover 220 is tied to the sheathing board 110 via the coping.

Next, a method for attaching the cover 150 to the roof material 130 will be described. The mounting method of the cover 150 according to the present embodiment includes an assembly step of covering the roof material 130 with the cover 150 and a joining step of supplying an adhesive to join.

As an assembly process, the cover 150 is laid out on the roof material 130 . For example, in this embodiment, an example in which one cover 150 is attached to three roof materials 130 arranged in the width direction is shown. In the assembling process, the covers 150 are sequentially mounted from the row on the ridge side to the row on the eaves side in order by a fixed width or by one row extending in the width direction.

Specifically, the cover 150 is moved toward the ridge while inserting the lower edge of the eaves side of the roof material 130 to be mounted into the opening formed between the top plate 151 and the bottom plate 153 of the cover 150 . , the top plate 151 is placed on the roof material 130 . From the second row onwards, the edge of the top plate 151 of the cover 150 is positioned between the surface of the roofing material 130 to be mounted and the bottom plate 153 of the cover 150 previously attached to the roofing material 130 adjacent to the ridge side. It is installed while inserting it into the gap formed between them. As described above, the covers 150 arranged in the vertical direction are arranged so as to partially overlap each other.

Then, after the covers 150 are attached to a certain number of roofing materials 130, an adhesive is supplied and joined as a joining step. In the bonding process, an adhesive is supplied using, for example, an injection device 156 shown in FIG. The injection device 156 has a holding portion 156a forming a space capable of accommodating the adhesive, and a tubular nozzle 156b communicating with the holding portion 156a. The nozzle 156b is configured in a tapered shape so that the tip side becomes thinner in one direction. That is, the nozzle 156b has a thickness that gradually increases from the distal end to the proximal end, so that the cover 150 can be inserted while widening the gap between the covers 150 by the nozzle 156b. Further, in the injection device 156, when the nozzle 156b is inserted into the gap between the bottom plate 153 and the top plate 151 of the pair of covers 150 that are partially overlapped and arranged in the vertical direction, the tip of the nozzle 156b becomes the adhesive portion. A position regulating portion may be provided at a positioned position near the edge portion 153a of the bottom plate 153 .

As a bonding step, the tip of the nozzle 156b of the injection device 156 is inserted into the gap between the bottom plate 153 and the top plate 151 of a pair of covers 150 that are partially overlapped in the vertical direction, and positioned at a predetermined position. , the adhesive is discharged from the nozzle 156b. After that, when the injection device 156 is pulled out, the gap between the covers 150 narrows, so that the adhesive filled in a predetermined amount spreads and hardens to form an adhesive layer 155 . For example, the injection amount of the adhesive is set to the amount that reaches the back side of the top plate 151 and the front side of the bottom plate 153 from the edge portion 153a and the edge portion 151a when the adhesive spreads.

The adhesive layer 155 is arranged on the edge portion 153 a of the bottom plate 153 . It is arranged in the first region P1 between the back surface side of the bottom plate 153 of one cover 150 and the front surface side of the top plate 151 of the other cover 150, and joins the multiple covers 150 together. In addition, the adhesive layer 155 is arranged from the edge portion 153a of the bottom plate 153 to the second region P2 between the back surface of the roofing material 130 arranged opposite to the front side of the bottom plate 153, and connects the roofing material 130 and the bottom plate 153. Join. Furthermore, the adhesive layer extends to one side of the edge portion 153a of the bottom plate 153, and extends to the third region P3 between the front surface of the top plate 151 and the back surface of the roofing material 130 arranged to face the front side of the top plate 151. By being arranged, the top plate 151 and the back surface of the roof material 130 on the upper side are joined. Further, the adhesive layer 155 is arranged in a region between the top plate 151 and the bottom plate 153 beyond the edge 151a of the top plate 151 of the other cover 150 which is overlaid on the back side of the bottom plate 153. The plate 151 and the roof material 130 on the back side of the top plate 151 are joined. The adhesive layer 155 is arranged around the edge portion 153 a of the bottom plate 153 from the front side to the back side. Further, the adhesive layer 155 is arranged from the edge 151a of the top plate 151 to the back side of the top plate 151 and adheres to the surface of the roof material 130 as well.

Therefore, the adhesive layer 155 allows the roof material 130 facing the front surface and the back surface of the bottom plate 153 of the ridge-side cover 150, the surface of the top plate 151 of the eaves-side cover 150, and the edge. 151a, the back surface, and the roofing material 130 arranged to face the back surface are joined.

By repeating the assembling process and the bonding process as many times as necessary, the attachment of the cover 150 to the roof is completed.

According to the cover 150 and the roof structure 1 configured in this way, when the roof material 130 deteriorates or deteriorates in appearance due to aging or the like, the roof material 130 is covered with the cover 150 to improve the appearance. be able to.

Further, according to the roof structure 1 according to the above-described embodiment, the plurality of covers can be easily and firmly joined by arranging the adhesive layer in the gaps between the plurality of covers that are partially overlapped. . In addition, it is easier to maintain the bonding strength of the adhesive than in the case where the adhesive is applied to the surface of the roofing material, which generally tends to adhere to dirt and the like. In addition, compared to the case of applying to the surface of the roofing material 130 where dirt is likely to adhere, pretreatment such as high-pressure washing of the surface to be coated can be omitted, and the number of steps can be reduced. Compared to the case where the entire surface of the roof material is adhered, it can be fixed firmly by partially adhering it at a small number of places. Therefore, dismantling work is facilitated by joining at one or several points near the edge.

Furthermore, by arranging the adhesive in the vicinity of the edge of the bottom plate 153 of the cover, the adhesive is applied between the bottom plate 153 on the front side and the back surface of the roof material 130 arranged on the front side of the side plate, and on the cover 150 on the back side. By turning between the back surface of the top plate 151 and the roofing material 130, the joining with the roofing material 130 is also performed at the same time, so that more effective joining can be realized.

In addition, this invention is not limited to embodiment mentioned above. For example, in the above example, after assembling the plurality of covers 150 to the roofing material 130, an adhesive layer is placed between the bottom plate 153 of each cover 150 and the top plate 151 of the cover 150 arranged next to the cover 150. Although an example of fixing by injection has been shown, as another embodiment, in addition to the gaps between the covers 150, the roof material 130 and each cover 150 are further joined by an adhesive layer 159 as shown in FIG. good too. For example, before putting the cover 150 on the surface of the roofing material 130 and assembling it, an adhesive material is applied in advance to the surface of the roofing material 130 or the back surface of the top plate of the cover 150, so that each roofing material 130 and the roofing material 130 are attached. Each cover 150 is joined. Furthermore, after assembly, an adhesive may be filled between overlapping portions of the covers 150 adjacent in the longitudinal direction to join them.

In the above example, the top plate 151 and the bottom plate 153 extend parallel to each other, and the side plates 152 are arranged such that the angle between the top plate 151 and the side plates 152 is an obtuse angle and the angle between the side plates 152 and the bottom plate 153 is an acute angle. Although an example of tilting has been shown, it is not limited to this. For example, as another embodiment, like a cover 150A shown in FIG. 10, the top plate 151 and the bottom plate 153 may extend parallel to each other, and the side plates 152 may extend perpendicularly to the top plate 151 and the bottom plate 153. . Even in this case, the covers 150 can be easily and firmly joined by disposing the adhesive layer 155 in the first region P1 and the regions P2 to P3 between the covers 150A that are arranged to overlap each other.

In the example described above, the adhesive layer 155 is formed between the bottom plate 153 and the front side in addition to the first region P1 between the back side of the bottom plate 153 of one cover 150 and the front side of the top plate 151 of the other cover 150. In the second region P2 between the back surface of the roofing material 130, the third region P3 between the top plate 151 and the back surface of the roofing material 130 facing the front side, and the region between the top plate 151 and the bottom plate 153 Although many examples have been shown, the present invention is not limited to these.
