Summary of the Invention

Problems to be Solved by the Invention

[0011] However, in such a ventilation gable, since it is fixed above the wind - break board, the ventilation gable cannot be installed until the construction on the outer wall part side is completed, and there were cases where the ventilation gable could not be installed quickly. That is, the construction on the outer wall part side is carried out by an outer wall construction contractor, and the construction on the roof part side is carried out by a roof construction contractor. Even if the roof construction contractor has completed the construction of the roof materials, the ventilation gable cannot be installed until the construction of the wind - break board by the outer wall construction contractor is completed, and there were cases where the construction on the roof part side could not be completed efficiently.

[0012] In addition, when constructing the ventilation gable, it was necessary to separately prepare wood as purlins, and there was a problem that the number of members required for construction increased.

[0013] This invention was made to solve the above - mentioned problems, and an object thereof is to provide a spacer and a ventilation gable structure that improve construction efficiency.

[0023] With such a configuration, the positioning of the spacer becomes easy.

[0024] The invention according to claim 13 is the invention according to claim 5, wherein the inclined part is arranged to contact the lower surface of the inclined surface.

[0025] With such a configuration, the strength of the gable board member of the part supported by the inclined part and the support part is improved.

[0029] With such a configuration, the strength of the gable board member of the part supported by the inclined piece is improved.

[0030] As described above, in the invention according to claim 1, since the gable board can be inserted into the space between the vertical part and the gable base after the construction on the roof part side, the construction becomes efficient.

[0031] In addition to the effect of the invention according to claim 1, in the invention according to claim 2, when the ridge member is installed so as to abut on the upper surface of the inclined part, the strength of the ridge member at the part supported by the support part and the rising part is improved, so that the mounting state of the ridge member is stabilized.

Embodiments for Carrying Out the Invention

[0039] FIG. 1 is a perspective view of the spacer according to an embodiment of the present invention, and FIG. 2 is an enlarged side view of the spacer shown in FIG. 1.

[0040] Referring to FIGS. 1 and 2, the spacer 1 is formed by bending a flat plate made of a steel plate material such as a galvanized steel plate (registered trademark) having a long rectangular shape in a front view in the short side direction, and includes a hanging portion 2 extending vertically downward, an inclined portion 3 extending obliquely downward from the upper end of the hanging portion 2, a fixing portion 5 abutting on the upper surface of a roof portion (not shown) to be described later, and a support portion 4 connecting the inclined portion 3 and the fixing portion 5. Further, the spacer 1 includes a rising portion 6 connected to the lower end of the fixing portion 5 and extending upward until reaching the same virtual plane 9 as the inclined portion 3, and an inclined piece 7 connected to the upper end of the rising portion 6 and extending toward the inclined portion 3 side. Further, a water stop material 8 made of an elastic body or the like extending in the longitudinal direction is attached to the inner side surface of the hanging portion 2.

[0041] The angle θ formed between the hanging portion 2 and the inclined portion 3 1 is set to 65 degrees. The angle θ formed between the inclined portion 3 and the support portion 4 2 , the angle θ formed between the support portion 4 and the fixing portion 5 3 , the angle θ formed between the fixing portion 5 and the rising portion 6 4 , and the angle θ formed between the rising portion 6 and the inclined piece 7 5 are each set to 90 degrees. The heights of the support portion 4 and the rising portion 6 (the lengths in the direction orthogonal to the longitudinal direction of the spacer 1) are each set to 20 mm.

[0042] Next, the ventilation building according to the embodiment of the present invention will be described.

[0043] FIG. 3 is a perspective view of the ventilation building according to the embodiment of the present invention, and FIG. 4 is a schematic end view taken along line IV-IV of the ventilation building shown in FIG. 3.

[0044] Referring to FIGS. 3 and 4, the ventilation building 11 is mainly composed of a building plate member 20 and a ventilation member 30 attached to the lower surface of the building plate member 20.

[0045] The gable plate member 20 is formed by bending a flat plate made of a steel plate material such as a galvanized steel plate having a longitudinally long rectangular shape in a short side direction, and includes an inclined surface 23 extending obliquely downward and a vertical surface 22 extending vertically downward from the apex 41 of the inclined surface 23. Further, a plurality of ventilation openings 42 parallel to the longitudinal direction are formed on the underwater side of the inclined surface 23, and a plurality of mounting holes 43 for inserting fixing nails and the like, which will be described later, are formed in the longitudinal direction. Further, a vertical portion 24 extending substantially vertically downward is connected to the underwater side end portion of the inclined surface 23, and a flange portion 25 extending outward substantially parallel to the inclined surface 23 is connected to the lower end portion of the vertical portion 24. Further, a folded-back portion 26 is formed at the lower end portion of the vertical surface 22 so as to fold back on the inner side surface.

[0046] The ventilation member 30 is formed by bending a flat plate made of a steel plate material such as a galvanized steel plate having a longitudinally long rectangular shape in a short side direction, and includes a contact portion 35 that contacts the lower surface of the inclined surface 23 of the gable plate member 20 in an installed state, a first flat plate portion 31 that is connected to the underwater side end portion of the contact portion 35 and extends substantially vertically downward, a second flat plate portion 32 that is connected to the upper water side end portion of the contact portion 35 and extends so as to block a ventilation path perpendicular to the contact portion 35, a third flat plate portion 33 that is connected to the lower end portion of the first flat plate portion 31 and extends in the underwater side direction in a parallel state with the inclined surface 23, a fourth flat plate portion 34 that is connected to the end portion of the second flat plate portion 32 opposite to the contact portion 35 and extends in the upper water side direction in a parallel state with the inclined surface 23, and a rising piece 36 that is connected to the upper water side end portion of the fourth flat plate portion 34 and extends toward the inclined surface 23 perpendicular to the fourth flat plate portion 34. Further, first ventilation openings 44 are formed at predetermined intervals in the longitudinal direction on the upper side of the first flat plate portion 31. Further, second ventilation openings 45 are formed at predetermined intervals in the longitudinal direction on the lower side of the second flat plate portion 32. Further, a seal member 46 made of an elastic body or the like extending in the longitudinal direction is attached to the lower surface of the fourth flat plate portion 34.

[0047] As described above, the ventilation gable 11 shown in FIG. 4 is an integrated structure of the gable plate member 20 and the ventilation member 30.

[0048] Next, the attachment of the ventilation gable structure using the spacer shown in FIG. 1 to the roof portion will be described.

[0049] FIG. 5 is a schematic end view showing the attachment state of the ventilation building structure using the spacer shown in FIG. 1 to the single-slope roof, FIG. 6 is a schematic end view showing the attachment state of the spacer shown in FIG. 1 to the single-slope roof, and FIG. 7 is a schematic end view showing the state after the ventilation building shown in FIG. 4 is attached.

[0050] Referring to FIG. 5, the single-slope roof 12 has an outer wall portion 71 extending vertically downward, and a roof portion 72 extending obliquely downward with a rectangular opening 73 formed longitudinally at the apex side portion thereof. The outer wall portion 71 is composed of a wind-breaking base 76 extending vertically downward, an outer wall material 78 installed below the wind-breaking base 76, and a wind-breaking plate 77 attached to the outside of the wind-breaking base 76. Note that since the wind-breaking plate 77 is installed after the ventilation building structure is attached, it does not exist at the stage before the ventilation building structure is attached. The roof portion 72 is composed of a sheathing board 75 installed on the purlin 79, and a roofing material 74 installed on the sheathing board 75 via a waterproof paper and an underlay not shown in the figure.

[0051] Referring to FIG. 6, the spacer 1 is lowered from above so as to cover the apex side portion of the opening of the single-slope roof on the single-slope roof 12 configured as described above. Then, the fixing portion 5 is brought into contact with the upper surface of the roof portion 72 so that the lower end portion of the fixing portion 5 is located on the apex side from the opening 73. In this state, screws 91 are driven from above the fixing portion 5 toward the roof portion 72 to fix the spacer 1 to the roof portion 72. In this way, when the lower end portion of the fixing portion 5 is installed along the apex side of the opening 73, the positioning of the spacer 1 becomes easy and the construction becomes efficient.

[0052] At this time, the hanging portion 2 is separated from the tip 81 on the wind-breaking base 76 side of the roof portion 72 and extends vertically downward in a parallel state separated from the wind-breaking base 76 by a predetermined distance. Then, the spacer 1 is fixed to the roof portion 72 in a state where the hanging portion 2 and the tip 81 of the roof portion 72 are separated from each other so that a space 82 having a width capable of installing the wind-breaking plate 77 is provided between the hanging portion 2 and the wind-breaking base 76.

[0053] Here, the relationship of the horizontal distances of each part will be described. The horizontal distance D from the vertical part 2 to the lower end of the fixed part 5 (the opening 73 in this example) 1 is the horizontal distance D from the vertical part 2 to the tip 81 2 and the horizontal distance D from the tip 81 to the lower end of the fixed part 5 (the opening 73 in this example) 3 and is the sum of them (D 2 +D 3 ). Also, referring to FIG. 7 together, the horizontal distance D 2 is set to be longer than the thickness T of the wind-breaking plate 77. Due to such a configuration, the wind-breaking plate 77 can be inserted later between the vertical part 2 and the wind-breaking base 76.

[0054] The inclined part 3 extends obliquely downward in a parallel state at a predetermined distance from the upper end of the vertical part 2 with respect to the roof part 72. The effects of such a configuration will be described later.

[0055] Next, the ventilation gable 11 is lowered from above in the direction of the arrow of the two-dot chain line shown in FIG. 6. Then, referring to FIG. 7, first on the outer wall part 71 side, the lower end of the vertical part 2 is inserted into the folded-back part 26. After that, on the roof part 72 side, the inclined surface 23 is placed on the inclined part 3 and the inclined piece 7. Then, the inclined part 3 is arranged to contact the lower surface of the inclined surface 23.

[0056] By configuring in this way, the strength of the gable plate member 20 of the part supported by the inclined part 3 and the support part 4 is improved. Therefore, the mounting state of the gable plate member 20 is stabilized.

[0057] Regarding the relationship between the spacer 1 and the ventilation member 30, when the distance in the direction perpendicular to the roof slope is taken as the thickness t of the ventilation member 30, the thickness t is set to about 18 mm. As described above, the heights of the support part 4 and the rising part 6 are 20 mm. Therefore, since the heights of the support part 4 and the rising part 6 and the thickness t of the ventilation member 30 support the gable plate member 20 in a substantially the same state considering the folded-back part at the end, the mounting state of the gable plate member 20 is more stable.

[0058] Also, as described above, the rising portion 6 extends upward until it reaches the same virtual plane 9 of the inclined portion 3. Therefore, when the gable plate member 20 is installed so as to abut on the upper surface of the inclined portion 3 in this way, the rising portion 6 abuts on the inclined surface 23. And the support portion 4 and the rising portion 6 support perpendicularly to the inclined surface 23 at a position separated by a predetermined distance. Since the gable plate member 20 is supported at two points in this way, the mounting state of the gable plate member 20 becomes stable.

[0059] Furthermore, on the outer wall portion 71 side, the vertical surface 22 abuts on the hanging portion 2, and on the roof portion 72 side, the inclined surface 23 abuts on the inclined portion 3.

[0060] In this way, since it is in contact with the gable plate member 20 continuously from the hanging portion 2 of the spacer 1 to the inclined portion 3, the thickness at the top of the outer wall portion 71 side and the roof portion 72 side increases compared with the conventional ventilation gable, and the strength of the contacting portion is improved. Therefore, even when the wind blows from the outside, the vertical surface 22 of the gable plate member 20 does not turn up, and the mounting state becomes more stable.

[0061] Also, the inclined piece 7 extends on the same virtual plane 9 of the inclined portion 3 toward the inclined portion 3 side, and the inclined surface 23 also abuts on the inclined piece 7. With this configuration, since the strength of the gable plate member 20 at the portion supported by the inclined piece 7 is improved, the mounting state of the gable plate member 20 becomes more stable.

[0062] When attaching the ventilation gable 11 to the single - flow roof 12, the fixing nails 92 are inserted and driven in with waterproof packing attached to the lower side of each of the mounting holes 43 of the inclined surface 23 shown in FIG. 3. Thereby, the attachment of the ventilation gable structure 10 to the single - flow roof 12 is completed.

[0063] In this way, since the ventilation gable structure 10 can be attached only by fixing to the roof portion 72 side, it is not necessary to prepare a purlin for fixing to the outer wall portion 71 side, and the number of members required for construction is reduced.

[0064] Finally, a wind board 77 is inserted between the hanging part 2 and the wind break base 76. At this time, since the wind board 77 compresses and deforms the water stop material 8, the gap between the hanging part 2 and the wind board 77 can be hermetically closed to form a highly reliable water stop structure. Then, the installation of the wind board 77 is completed by filling a sealing material between the inner surface on the lower side of the wind board 77 and the outer surface on the upper side of the outer wall member 78.

[0065] Here, the construction on the roof side is carried out by a roofing contractor, and the construction on the outer wall side is carried out by an outer wall contractor. And when the roofing contractor constructs the building part, a ventilation building is attached so as to cover from the upper part of the wind board to the roof top. As described above, the spacer 1 is fixed to the roof part 72 in a state where the hanging part 2 and the tip 81 of the roof part 72 are separated from each other so that a space 82 with a width capable of installing the wind board 77 is provided between the hanging part 2 and the wind break base 76. Also, since the building board member 20 is continuously in contact from the hanging part 2 to the inclined part 3 of the spacer 1, the ventilation building structure 10 can be stably attached only by fixing it to the roof part 72 side without fixing the ventilation building structure 10 with nails or the like from the outer wall part 71 side. Therefore, the roofing contractor does not need to fix it on the outer wall part 71 side as in the conventional case. Also, since a space 82 with a width capable of installing the wind board 77 is provided between the hanging part 2 and the wind break base 76, the outer wall contractor can later insert the wind board 77 into the space 82 after constructing the ventilation building 11. That is, the roofing contractor can complete the construction of the ventilation building 11 without waiting for the completion of the construction of the wind board 77 by the outer wall contractor. Therefore, the construction on the roof part 72 side becomes efficient.

[0066] Also, from the apex 41 to the central position of the inclined surface 23, since the inclined surface 23 is continuously supported by the inclined part 3, the support part 4, and the rising part 6, there is no need to prepare a crossbar for supporting the ventilation building 11 between the roof part 72 and the ventilation building 11, and the number of members required for the construction is reduced.

[0067] In the ventilated state, as indicated by the double arrow 83 in FIG. 5, the air rising from the opening 73 of the roof portion 72 passes through the first ventilation port 44 and the second ventilation port 45 of the ventilation member 30. Then, it is discharged outward from the ventilation port 42 of the gable plate member 20. This prevents the air warmed in the attic space from staying and prevents the occurrence of condensation and decay.

[0068] In addition, in the above-described embodiment, the structure of the single-slope roof is specified. However, any other structure can be similarly applied as long as it has a gable base extending vertically downward and a gable board attached outside the gable base, and a roof portion extending obliquely downward.

[0069] Also, in the above-described embodiment, an opening was formed in the apex side portion of the roof portion, but the opening may not be provided.

[0070] Furthermore, in the above-described embodiment, the spacer is installed together with the ventilation building, but it may be installed together with a building component that does not have a ventilation structure. In that case, the structure shown in FIG. 8 is obtained. That is, the spacer 1 is installed in a portion between the roof part 72 and a building component 52 installed above the roof part 72 in the building part of the single-slope roof 12 having a wind-breaking base 76 extending vertically downward and a roof part 72 extending obliquely downward. FIG. 8 is a schematic end view showing the attachment state of the building component structure using the spacer shown in FIG. 1 to the single-slope roof. Referring to FIG. 8, the building component structure 51 is installed in the building part of the single-slope roof 12 having a wind-breaking base 76 extending vertically downward and a roof part 72 extending obliquely downward. The building component structure 51 includes a building component 52 having an inclined surface 23 extending obliquely downward in a parallel state at a predetermined distance from the roof part 72 and a vertical surface 22 extending vertically downward from the apex of the inclined surface 23, and a spacer 1 attached between the roof part 72 and the building component 52. The spacer 1 is separated from the tip 81 on the wind-breaking base 76 side of the roof part 72, and has a vertical part 2 extending vertically downward in a parallel state at a predetermined distance from the wind-breaking base 76, an inclined part 3 extending obliquely downward in a parallel state at a predetermined distance from the roof part 72 from the upper end of the vertical part 2, a fixing part 5 abutting on the upper surface of the roof part 72, and a support part 4 connecting the inclined part 3 and the fixing part 5. Further, the spacer 1 is provided with a space 82 having a width in which a wind-breaking plate 77 can be installed between the vertical part 2 and the wind-breaking base 76, and is fixed to the roof part 72 in a state where the vertical part 2 and the tip 81 of the roof part 72 are separated. By configuring in this way, after the construction on the roof part 72 side, the wind-breaking plate 77 can be inserted into the space 82 between the vertical part 2 and the wind-breaking base 76, so that the construction becomes efficient. Furthermore, the spacer 1 includes a rising part 6 connected to the lower end of the fixing part 5 and extending upward until it reaches the same virtual plane 9 as the inclined part 3. Thereby, the strength of the building component 52 supported by the support part 4 and the rising part 6 is improved. Furthermore, the spacer 1 includes an inclined piece 7 connected to the upper end of the rising part 6 and extending on the same virtual plane 9 as the inclined part 3 toward the inclined part 3 side. Thereby, since the strength of the building component 52 of the portion supported by the inclined piece 7 is improved, the attachment state of the building component 52 becomes stable.Furthermore, the ridge structure 52 here includes not only those without a ventilation opening on the inclined surface 23 as shown in Fig. 8, but also those with a ventilation opening 42 on the inclined surface 23 as shown in Fig. 5. Also, the ridge structure 51 here includes not only those without a ventilation path from the inside to the outside as shown in Fig. 8, but also those with a ventilation path as indicated by the double-headed arrow 83 in Fig. 5.

[0071] Furthermore, in the above embodiment, the support part is connected perpendicularly to the inclined part and the fixed part, but it does not have to be perpendicular. For example, it may be inclined upward or downward.

[0072] Furthermore, in the above embodiment, the rising part is connected perpendicularly to the fixed part, but it does not have to be perpendicular. For example, it may be inclined upward or downward.

[0073] Furthermore, in the above embodiment, the angle formed by the vertical part and the inclined part was a specific angle, but other angles may also be acceptable. It can be appropriately set within the range of acute angles according to the slope of the roof to be installed.

[0074] Furthermore, in the above embodiment, the entire surface of the fixed part is in contact with the upper surface of the roof part, but other shapes may be acceptable as long as it can be fixed to the roof part. For example, a part of the fixed part may be in contact with the roof part.

[0075] Furthermore, in the above embodiment, the support part is arranged parallel to the rising part, but it does not have to be arranged parallel.

[0076] Furthermore, in the above embodiment, the spacer includes a rising part and an inclined piece, but the rising part and the inclined piece may be absent.

[0077] Furthermore, in the above embodiment, the rising part is formed to extend upward until it reaches the same virtual plane as the inclined part, but it does not have to reach the virtual plane.

[0078] Furthermore, in the above-described embodiment, the inclined piece is formed to extend on the same virtual plane of the inclined portion toward the inclined portion side, but it may extend toward the side opposite to the inclined portion. Also, it does not necessarily have to extend on the same virtual plane of the inclined portion.

[0079] Furthermore, in the above-described embodiment, a water stop material is attached to the inner side surface of the vertical portion, but the water stop material may be omitted.

[0080] Furthermore, in the above-described embodiment, the vertical portion is formed to extend vertically downward in a parallel state at a predetermined distance from the wind-breaking base, but if a space with a width where a wind-breaking plate can be installed can be provided between the vertical portion and the wind-breaking base, it does not necessarily have to extend vertically downward in a parallel state.

[0081] Furthermore, in the above-described embodiment, the ventilation building includes a ventilation member, but the ventilation member may be omitted.

[0082] Furthermore, in the above-described embodiment, the spacer is made of a steel plate, but it may be made of other materials.

[0083] Furthermore, in the above-described embodiment, a folded-back portion is formed in the ventilation building, but the folded-back portion may be omitted.

[0084] Furthermore, in the above-described embodiment, the spacer is formed by bending a single flat plate, but it may be formed by connecting a plurality of members.

[0085] Furthermore, in the above-described embodiment, the ventilation member has a so-called baffle structure with a specific shape, but it may have other shapes as long as it has a ventilation path. It is preferable to have a waterproof function of preventing rainwater from entering from the outside to the inside by making the ventilation path meander or serpentine, or by subdividing it into a large number of small-diameter ventilation paths.

[0086] Furthermore, in the above-described embodiment, a plurality of ventilation openings were formed longitudinally on the underwater side of the inclined surface. However, they may be formed at other positions such as other positions on the inclined surface or the vertical portion, and the number thereof is not limited either.
