【０００４】
【発明が解決しようとする課題】
前述した従来の出窓の屋根であれば、雨滴が屋根板に衝突したことにより発生する振動音が硬質発泡ウレタンで緩衝され、その振動音が室内に伝わることを低減できるが、その振動音の緩衝が十分ではなく、振動音が室内に伝わることを十分に低減できない。
【０００５】
本発明は、前述の課題に鑑みなされたものであって、その目的は、雨滴が屋根板に衝突したことにより発生する振動音が室内に伝わることを十分に低減できるようにした建物用小屋根を提供することである。
【０００６】
【課題を解決するための手段】
第１の発明は、屋根板１と回り縁２と天板３と背板４で空洞部５を有する屋根本体６と、
この屋根本体６の空洞部５内に注入充填して設けた独立気泡のポリウレタンフォームと、
前記屋根板１の裏面に貼着した制振材シート８と、
前記空洞部５内に設けた吸音材９で形成したことを特徴とする建物用小屋根である。
【０００７】
第２の発明は、第１の発明において独立気泡のポリウレタンフォームは、独立気泡の硬質ポリウレタンフォーム７で、吸音材９は、ブロック形状に形成されたグラスウール又は吸音フェルトで、天板３の空洞部５側面に貼着してある建物用小屋根である。
【０００８】
【作 用】
第１の発明によれば、屋根板１に雨滴が衝突することによる振動の発生が制振材シート８で低減され、発生する振動音が低減される。
この発生した振動音は、ポリウレタンフォームと吸音材８で室内への伝達が低減される。
よって、雨滴の衝突による振動音が室内に伝達することが大幅に低減した建物用小屋根である。
また、独立気泡のポリウレタンフォームを屋根本体６の空洞部５内に注入充填したので、屋根板１と回り縁２と天板３と背板４の各連結部から雨水等が浸入した時に、その浸入した雨水がポリウレタンフォームの内部を伝わって室内側まで流れることがない。
【０００９】
第２の発明によれば、吸音材９がブロック形状に形成されたグラスウール又は吸音フェルトであるから、吸音効果が大きくなる。
また、吸音材９を天板３に貼着したことで、天板３に対して容易に固定する事ができると共に、硬質ポリウレタンフォームを注入充填する際に吸音材９の天板３上における取付け位置がずれる事がないし、その吸音材９の弾性復元力で屋根板１が上にふくらむことがない。
また、硬質ポリウレタンフォーム７を用いたことによって屋根板１と回り縁２、天板３と背板４の連結部の強度が向上する。
【００１０】
【発明の実施の形態】
図１と図２と図３に示すように、屋根板１と回り縁２と天板３と背板４で空洞部５を有する屋根本体６を形成し、その屋根本体６の空洞部５に独立気泡のポリウレタンフォーム、好ましくは独立気泡の硬質ポリウレタンフォーム７を注入充填すると共に、屋根板１の裏面に制振材シート８を貼着し、天板３の上面（空洞部５側面）に吸音材９を設けて建物用小屋根、例えば出窓の屋根を形成している。
【００１１】
前記屋根板１はアルミニウム板や鉄板などを板金加工したもので、平面形状が長方形の主屋根板１０と、この主屋根板１０の両端部と連続した一対の平面形状が略三角形の端部屋根板１１と、前記主屋根板１０、端部屋根板１１の室内側縁と連続した主取付縦片１２、端部取付縦片１３を有する。この屋根板１は平面形状が略台形形状である。
前記主屋根板１０、端部屋根板１１の室外側縁は室内側に向けて鉤形に折り曲げられて主取付鉤片１４、端部取付鉤片１５を形成している。
前記主屋根板１０の裏面と一対の端部屋根板１１の裏面に亘って前記制振材シート８が貼着してある。
この制振材シート８は、屋根板１の中央部分に貼着され、屋根板１の室内側部分、室外側部分、左右端部分には制振材シート８が存在しない。
これによって、回り縁２と屋根板１の連結部、屋根板１と背板４の連結部に、硬質ポリウレタンフォーム７が充填されるので、その各連結部の連結強度を硬質ポリウレタンフォーム７で向上できる。
つまり、硬質ポリウレタンフォーム７は接着性に優れているので、その硬質ポリウレタンフォーム７が回り縁２と屋根板１、屋根板１と背板４にそれぞれ亘って接着するから、強固に連結できる。
【００１２】
前記回り縁２はアルミニウム板や鉄板など金属製で、図３に示すように、縦板２０、上横板２１、下横板２２で断面略コ字形状で、その縦板２０の上縁寄り外面に屋根板取付片２３を有し、前記下横板２２に上向きの天板取付片２４を有する形材を用いている。この天板取付片２４は内向凹部２５を有する。
前記回り縁２は図１に示すように前述の形材の長手方向両端寄り部と端部を内側に向けて折り曲げて平面形状が屋根板１の室外側縁と同一の略台形形状としてある。
具体的には、縦板２０以外の部分をＶ字状に切断して縦板２０を折り曲げてＶ字状切断端面を接合してある。
このＶ字状切断端面の接合部分２６の水密性は硬質ポリウレタンフォーム７で保持される。つまり、硬質ポリウレタンフォーム７が独立気泡であるから、接合部分２６から浸入した雨水等が硬質ポリウレタンフォーム７の内部を通って室内側まで流れることがない。
【００１３】
前記硬質ポリウレタンフォーム７とはポリウレタンフォームの１種で、性質的には、変形せず一定荷重に対してフォームが破壊を起こし原形に回復しないもの、原料的には、３官能以上の多官能ポリオールを主原料とするものである。
なお、ポリウレタンフォームとしては軟質ポリウレタンフォーム、半硬質ポリウレタンフォームがあり、軟質ポリウレタンフォームは性質的には、外部荷重に対し自由に変形し、荷重を除去するともとの形にもどり、タワミ性をもったもので、原料的には、ＭＷ３０００以上の３官能ポリエーテルを主原料とするものである。半硬質ポリウレタンフォームは性質的には、軟質ポリウレタンフォームよりも固いもので、原料的には、ＭＷ３０００以上の３官能ポリエーテルを主原料とするものである。
なお、硬質ポリウレタンフォーム７の代りに独立気泡の軟質ポリウレタンフォーム、独立気泡の半硬質のポリウレタンフォームを用いても良い。
【００１４】
前記天板３は屋根板１と略同一の平面形状が略台形状で、その室外側端縁３１が図３に示すように回り縁２の内向凹部２５に嵌入して取付けられる。
天板３の室内側端縁３２は一直線状である。
前記屋根板１と回り縁２は図３に示すように、屋根板１の主取付鉤片１４、端部取付鉤片１５を回り縁２の屋根板取付片２３に係止して連結される。
前記吸音材９は天板３の上面に貼着されている。この吸音材９は天板３の中央部に位置し、天板３の室外側部分、室内側部分、左右端部分には吸音材９が存在しない。
これによって、回り縁２と天板３の連結部、天板３と背板４の連結部に硬質ポリウレタンフォーム７が充填されるので、その各連結部の連結強度を硬質ポリウレタンフォーム７で向上できる。
【００１５】
また、吸音材９が天板３の上面に貼着されているので、硬質ポリウレタンフォームの発泡時に弾性圧縮変形した吸音材９の弾性復元力が硬質ポリウレタンフォーム７、天板３で支持され、屋根板１に伝わらないから、屋根板１が吸音材９の弾性復元力で上にふくらむことがない。
【００１６】
前記吸音材９は制振材シート８に貼着しても良い。
【００１７】
前記背板４は天板３の室内側端縁３２に固着具、例えば図示しないコ字状の釘で固着される。この背板４は屋根板１の主取付縦片１２、端部取付縦片１３と回り縁２の室内側端面に接して空洞部５を有する屋根本体６を形成している。
前述のように屋根本体６を組み立てした後に、背板４の孔４０から硬質ポリウレタンフォームを注入充填して空洞部５を硬質ポリウレタンフォーム７で埋め、出窓の屋根を形成する。
【００１８】
前記制振材シート８は振動を低減するものである。
前記吸音材９は、グラスウール、吸音フェルト、スポンジなど用いられる。好ましくは、ブロック形状に形成されたグラスウール又は吸音フェルトである。例えば、所定の高さを幅と長さを有する直方体形状である。具体的には、屋根本体６の左右長さが１８７０ｍｍ、室外側高さ５０ｍｍ、室内側高さ１５０ｍｍ、室内外側寸法３４０ｍｍの場合に、長さが１５００ｍｍ、厚さが５０ｍｍ、幅が２５０ｍｍの直方体である。
【００１９】
【発明の効果】
請求項１に係る発明によれば、屋根板１に雨滴が衝突することによる振動の発生が制振材シート８で低減され、発生する振動音が低減される。
この発生した振動音は、ポリウレタンフォームと吸音材８で室内への伝達が低減される。
よって、雨滴の衝突による振動音が室内に伝達することが大幅に低減した建物用小屋根である。
また、独立気泡のポリウレタンフォームを屋根本体６の空洞部５内に注入充填したので、屋根板１と回り縁２と天板３と背板４の各連結部に雨水等が浸入した時に、その浸入した雨水がポリウレタンフォームの内部を伝わって室内側まで流れることがない。
【００２０】
請求項２に係る発明によれば、吸音材９がブロック形状に形成されたグラスウール又は吸音フェルトであるから、吸音効果が大きくなる。
また、吸音材９を天板３に貼着したことで、天板３に対して容易に固定する事ができると共に、硬質ポリウレタンフォームを注入充填する際に吸音材９の天板３上における取付け位置がずれる事がないし、その吸音材９の弾性復元力で屋根板１が上にふくらむことがない。
また、硬質ポリウレタンフォーム７を用いたことによって屋根板１と回り縁２、天板３と背板４の連結部の強度が向上する。

[Patent Document 1]
JP-A-9-32182
[Problems to be solved by the invention]
In the case of the above-mentioned conventional bay window roof, the vibration noise generated by the raindrop colliding with the roof plate is buffered by the hard urethane foam, and the transmission of the vibration noise into the room can be reduced. However, it is not possible to sufficiently reduce the transmission of the vibration sound into the room.
[0005]
The present invention has been made in view of the above-described problems, and has as its object to provide a small roof for a building that can sufficiently reduce the transmission of vibration noise generated by raindrops colliding with a roof panel into a room. It is to provide.
[0006]
[Means for Solving the Problems]
The first invention is a roof body 6 having a hollow portion 5 with a roof panel 1, a peripheral edge 2, a top panel 3, and a back panel 4,
A closed-cell polyurethane foam injected and filled into the hollow portion 5 of the roof body 6;
A damping material sheet 8 adhered to the back surface of the roof plate 1;
A small roof for a building characterized by being formed of a sound absorbing material 9 provided in the hollow portion 5.
[0007]
In the second invention, the closed-cell polyurethane foam in the first invention is a closed-cell hard polyurethane foam 7, the sound-absorbing material 9 is glass wool or a sound-absorbing felt formed in a block shape, and the hollow portion of the top plate 3 is provided. It is a small roof for a building stuck on five sides.
[0008]
[Operation]
According to the first aspect of the present invention, the vibration caused by the raindrop colliding with the roof plate 1 is reduced by the damping material sheet 8, and the generated vibration noise is reduced.
The transmission of the generated vibration sound to the room is reduced by the polyurethane foam and the sound absorbing material 8.
Therefore, it is a small roof for a building in which the transmission of the vibration noise due to the collision of raindrops into the room is greatly reduced.
Further, since the closed-cell polyurethane foam is injected and filled into the hollow portion 5 of the roof main body 6, when rainwater or the like intrudes from the respective connection portions of the roof plate 1, the peripheral edge 2, the top plate 3, and the back plate 4, the infiltration is prevented. The rainwater does not flow down the interior of the polyurethane foam to the inside of the room.
[0009]
According to the second invention, since the sound absorbing material 9 is glass wool or sound absorbing felt formed in a block shape, the sound absorbing effect is increased.
In addition, since the sound absorbing material 9 is attached to the top plate 3, the sound absorbing material 9 can be easily fixed to the top plate 3, and the sound absorbing material 9 can be mounted on the top plate 3 when the hard polyurethane foam is injected and filled. The position does not shift, and the shingle 1 does not bulge upward due to the elastic restoring force of the sound absorbing material 9.
In addition, the use of the rigid polyurethane foam 7 improves the strength of the connecting portion between the roof panel 1 and the peripheral edge 2 and the connection between the top panel 3 and the back panel 4.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
As shown in FIGS. 1, 2 and 3, a roof main body 6 having a hollow portion 5 is formed by a roof panel 1, a peripheral edge 2, a top panel 3 and a back panel 4, and is independent of the hollow section 5 of the roof main body 6. A foamed polyurethane foam, preferably a closed-celled rigid polyurethane foam 7 is injected and filled, and a damping material sheet 8 is adhered to the back surface of the roof plate 1, and a sound absorbing material is attached to the upper surface of the top plate 3 (side surface of the hollow portion 5). 9 to form a small roof for a building, for example, a bay window roof.
[0011]
The roof shingle 1 is formed by sheet metal processing of an aluminum plate, an iron plate, or the like, and has a rectangular main roof shingle 10, and a pair of substantially rectangular triangular end roofs continuous with both ends of the main shingle 10. It has a plate 11, a main roof panel 10, and a main mounting vertical piece 12 and an end mounting vertical piece 13 which are continuous with the indoor side edge of the end roof panel 11. The roof plate 1 has a substantially trapezoidal planar shape.
The outside edge of the main roof plate 10 and the end roof plate 11 is bent into a hook shape toward the indoor side to form a main mounting hook 14 and an end mounting hook 15.
The damping material sheet 8 is stuck over the back surface of the main roof plate 10 and the back surface of the pair of end roof plates 11.
The damping material sheet 8 is adhered to the center portion of the roof plate 1, and the damping material sheet 8 does not exist on the indoor side portion, the outdoor side portion, and the left and right end portions of the roof plate 1.
As a result, the rigid polyurethane foam 7 is filled into the connecting portion between the peripheral edge 2 and the roof panel 1 and the connecting portion between the roof panel 1 and the back panel 4, so that the rigid polyurethane foam 7 can improve the connection strength of each connecting portion. .
That is, since the rigid polyurethane foam 7 is excellent in adhesiveness, the rigid polyurethane foam 7 adheres to the peripheral edge 2 and the roof shingle 1, and the roof shingle 1 and the back panel 4, respectively, so that the rigid polyurethane foam 7 can be strongly connected.
[0012]
The peripheral edge 2 is made of a metal such as an aluminum plate or an iron plate. As shown in FIG. 3, the vertical plate 20, the upper horizontal plate 21, and the lower horizontal plate 22 have a substantially U-shaped cross section. And a lower horizontal plate 22 having a top plate mounting piece 24 facing upward. The top plate mounting piece 24 has an inward concave portion 25.
As shown in FIG. 1, the peripheral edge 2 has a substantially trapezoidal shape having the same planar shape as the outdoor edge of the roof slab 1 by bending the above-described shaped member near both ends in the longitudinal direction and the end portion inward.
Specifically, a portion other than the vertical plate 20 is cut into a V shape, the vertical plate 20 is bent, and the V-shaped cut end faces are joined.
The watertightness of the joint portion 26 of the V-shaped cut end surface is maintained by the rigid polyurethane foam 7. That is, since the rigid polyurethane foam 7 is a closed cell, rainwater or the like that has entered from the joint portion 26 does not flow through the inside of the rigid polyurethane foam 7 to the indoor side.
[0013]
The rigid polyurethane foam 7 is a kind of polyurethane foam which is not deformed and does not recover to its original shape under a constant load without any deformation. Is the main raw material.
As the polyurethane foam, there are a flexible polyurethane foam and a semi-rigid polyurethane foam, and the flexible polyurethane foam is deformed freely in response to an external load, and returns to its original shape when the load is removed. As a raw material, a trifunctional polyether having a MW of 3000 or more is used as a main raw material. The semi-rigid polyurethane foam is harder in nature than the flexible polyurethane foam, and is mainly made of a trifunctional polyether having a MW of 3,000 or more as a main raw material.
Instead of the rigid polyurethane foam 7, closed-cell soft polyurethane foam or closed-cell semi-rigid polyurethane foam may be used.
[0014]
The top plate 3 has a substantially trapezoidal shape in substantially the same plane shape as the roof plate 1, and its outdoor-side edge 31 is fitted and attached to the inward concave portion 25 of the peripheral edge 2 as shown in FIG. 3.
The indoor side edge 32 of the top plate 3 is linear.
As shown in FIG. 3, the roof plate 1 and the peripheral edge 2 are connected by locking the main mounting hooks 14 and the end mounting hooks 15 of the roof panel 1 to the roof panel mounting pieces 23 of the peripheral edge 2.
The sound absorbing material 9 is stuck on the upper surface of the top plate 3. The sound absorbing material 9 is located at the center of the top plate 3, and the sound absorbing material 9 does not exist in the outdoor portion, the indoor side portion, and the left and right end portions of the top plate 3.
As a result, the rigid polyurethane foam 7 is filled into the connecting portion between the peripheral edge 2 and the top plate 3 and the connecting portion between the top plate 3 and the back plate 4, so that the rigid polyurethane foam 7 can improve the connection strength of each connecting portion.
[0015]
Further, since the sound absorbing material 9 is stuck on the upper surface of the top plate 3, the elastic restoring force of the sound absorbing material 9 elastically deformed by compression when the rigid polyurethane foam is foamed is supported by the rigid polyurethane foam 7 and the top plate 3, and the roof Since the sound is not transmitted to the plate 1, the roof plate 1 does not bulge upward due to the elastic restoring force of the sound absorbing material 9.
[0016]
The sound absorbing material 9 may be attached to the damping material sheet 8.
[0017]
The back plate 4 is fixed to the indoor side edge 32 of the top plate 3 with a fixing tool, for example, a U-shaped nail (not shown). The back plate 4 forms a roof main body 6 having a cavity 5 in contact with the main mounting vertical piece 12, the end mounting vertical piece 13 of the roof panel 1, and the indoor side end surface of the peripheral edge 2.
After assembling the roof main body 6 as described above, the hollow portion 5 is filled with the rigid polyurethane foam 7 by injecting and filling the rigid polyurethane foam from the hole 40 of the back plate 4 to form a bay window roof.
[0018]
The vibration damping material sheet 8 reduces vibration.
The sound absorbing material 9 is made of glass wool, sound absorbing felt, sponge, or the like. Preferably, it is a glass wool or a sound absorbing felt formed in a block shape. For example, it has a rectangular parallelepiped shape having a predetermined height, a width and a length. Specifically, when the left-right length of the roof main body 6 is 1870 mm, the outdoor-side height is 50 mm, the indoor-side height is 150 mm, and the indoor-outside dimension is 340 mm, the rectangular body has a length of 1500 mm, a thickness of 50 mm, and a width of 250 mm. It is.
[0019]

The transmission of the generated vibration sound to the room is reduced by the polyurethane foam and the sound absorbing material 8.
Therefore, it is a small roof for a building in which the transmission of the vibration noise due to the collision of raindrops into the room is greatly reduced.
In addition, since the closed-cell polyurethane foam is injected and filled into the hollow portion 5 of the roof main body 6, when rainwater or the like intrudes into the respective connecting portions of the roof plate 1, the peripheral edge 2, the top plate 3, and the back plate 4, the infiltration is prevented. The rainwater does not flow down the interior of the polyurethane foam to the inside of the room.
[0020]
According to the second aspect of the invention, since the sound absorbing material 9 is glass wool or sound absorbing felt formed in a block shape, the sound absorbing effect is increased.
