Description
本発明は、シート保持具、屋根構造、及び屋根構造の構築方法に関する。 This invention relates to a sheet holder, a roof structure, and a method for constructing a roof structure.
建造物の屋根構造において、屋根材の下方に断熱材又は遮熱材を設けることがある。特許文献１には、折板屋根材の下方に複数のボード状の断熱材を一様に敷設した屋根構造が開示されている。 In building roof structures, insulation or heat-shielding materials are sometimes provided beneath the roofing material. Patent Document 1 discloses a roof structure in which multiple board-shaped insulation materials are uniformly laid beneath a corrugated metal roofing material.
特許文献１に開示された屋根構造では、折板屋根材を支持するタイトフレームが梁の上に固定されている。タイトフレームは、梁の長手方向に直交する方向に突出したハネ部を備えている。隣り合う梁の上に固定された２つのタイトフレームを連結するジョイナーがハネ部に引っ掛けられて取り付けられており、ボード状の断熱材の端部がジョイナーに載置されている。 In the roof structure disclosed in Patent Document 1, a tight frame supporting the corrugated metal roofing material is fixed to the beam. The tight frame has a wing-shaped portion projecting in a direction perpendicular to the longitudinal direction of the beam. A joiner connecting two tight frames fixed to adjacent beams is attached by hooking it onto the wing-shaped portion, and the end of a board-shaped insulation material rests on the joiner.
近年、繊維系断熱材又は発泡プラスチック系断熱材から形成されたボードに代えて、放射熱に対して高反射率のシートを屋根材の下方に一様に設けることが提案されている。このようなシートは、繊維系断熱材又は発泡系断熱材から形成されたボードと比較して薄くて軽い。そのため、屋根構造の構築時において、ジョイナーにシートを載置するだけでは、風等によってシートが浮いたり飛んだりしてしまうおそれがある。 In recent years, it has been proposed to uniformly install a sheet with high reflectivity against radiant heat beneath the roofing material, as an alternative to boards made of fibrous or foamed plastic insulation. Such sheets are thinner and lighter than boards made of fibrous or foamed insulation. Therefore, when constructing a roof structure, simply placing the sheet on the joiners may cause it to float or be blown away by wind.
本発明は、屋根材の下方に設けられるシートを保持することを目的とする。 The present invention aims to hold a sheet installed beneath the roofing material.
本発明は、屋根材の下方において互いに横方向に隣り合うシートを保持するシート保持具に係り、隣り合うシートを下方から支持する下側部材と、隣り合うシートを間に挟んで下側部材に重ねられる上側部材と、を備え、下側部材は、隣り合うシートが載置される載置部と、隣り合うシートの間から上方に突出して載置部に設けられた突出部と、を有し、突出部は、載置部から上方に延びる第１延在部と、屋根材を支持する支持構造体に引っ掛け可能に第１延在部から曲げ返された第２延在部と、を有し、上側部材は、突出部を受入れ可能な形状に形成されており、上側部材が突出部を受入れた状態において、突出部の第２延在部は、上側部材を介して隣り合うシートを載置部に押付ける。 The present invention relates to a sheet holder for holding sheets adjacent to each other laterally below a roofing material, comprising a lower member that supports adjacent sheets from below, and an upper member that overlaps the lower member with the adjacent sheets in between, wherein the lower member has a mounting portion on which adjacent sheets are placed, and a projection that protrudes upward from between the adjacent sheets and is provided on the mounting portion, wherein the projection has a first extension portion that extends upward from the mounting portion, and a second extension portion that is bent back from the first extension portion so as to be hooked onto a support structure that supports the roofing material, and the upper member is formed in a shape that can receive the projection portion, and in a state in which the upper member has received the projection portion, the second extension portion of the projection portion presses the adjacent sheets to the mounting portion via the upper member.

本発明によれば、屋根材の下方に設けられるシートを保持することができる。 According to this invention, a sheet installed below the roofing material can be held in place.
以下、本発明の実施形態に係るシート保持具１００、屋根構造１、及び屋根構造１の構築方法について、図面を参照して説明する。屋根構造１は、例えば、工場、倉庫及び体育館等の建造物に適用される。 The sheet holder 100, roof structure 1, and method for constructing the roof structure 1 according to embodiments of the present invention will be described below with reference to the drawings. The roof structure 1 is applicable to buildings such as factories, warehouses, and gymnasiums.
図１は、屋根構造１の一部断面斜視図である。図１に示すように、屋根構造１は、建造物の梁間方向に延びる複数の梁２と、梁２に上方に突出するように設けられた複数のタイトフレーム３と、複数のタイトフレーム３に掛け渡された屋根材４と、を備えている。屋根材４は、建造物の最上部に位置し、建造物の内部空間の上部を覆う。図１では、屋根材４が折板である例が示されているが、屋根材４は、折板に限られない。 Figure 1 is a partial cross-sectional perspective view of the roof structure 1. As shown in Figure 1, the roof structure 1 comprises a plurality of beams 2 extending in the direction of the building's beams, a plurality of tight frames 3 provided to project upward from the beams 2, and roofing material 4 stretched across the plurality of tight frames 3. The roofing material 4 is located at the very top of the building and covers the upper part of the building's interior space. While Figure 1 shows an example where the roofing material 4 is a corrugated metal sheet, the roofing material 4 is not limited to corrugated metal sheets.
梁２は、建造物の桁行方向に間隔を空けて配置されており、不図示の柱に支持されている。隣り合う梁２の間には、不図示の桁が渡されている。図１では、梁２がＨ型鋼である例が示されているが、梁２は、H形鋼に限られず、例えば木桟であってもよい。 Beams 2 are spaced apart in the longitudinal direction of the building and supported by columns (not shown). A girder (not shown) spans between adjacent beams 2. Figure 1 shows an example where beams 2 are H-shaped steel; however, beams 2 are not limited to H-shaped steel and may, for example, be made of wooden battens.
タイトフレーム３は、各梁２の上に梁間方向に互いに間隔を空けて設けられている。タイトフレーム３は、溶接により梁２に固定されていてもよいし、ボルト締めにより梁２に固定されていてもよい。 The tight frames 3 are installed on each beam 2, spaced apart from each other in the direction between the beams. The tight frames 3 may be fixed to the beams 2 by welding or by bolting.
屋根構造１は、屋根材４の下方に配置された複数のシート５を更に備えている。シート５は、タイトフレーム３を梁２に固定した後であってタイトフレーム３に屋根材４を固定する前に、梁間方向に並べられると共に桁行方向に並べられ、隣り合う梁２の間の空間を覆う。 The roof structure 1 further comprises multiple sheets 5 positioned below the roofing material 4. The sheets 5 are arranged in both the inter-beam direction and the girder direction after the tight frames 3 are fixed to the beams 2 but before the roofing material 4 is fixed to the tight frames 3, covering the space between adjacent beams 2.
シート５は、複数のポリエチレンシートと複数のバブルポリエチレンシートとを交互に重ね更にアルミ箔で挟んだ素材である。アルミ箔は、放射熱を反射する遮熱効果を有し、バブルポリエチレンシートは、熱伝導を抑制する断熱効果を有する。つまり、シート５は、アルミ箔による遮熱効果と、バブルポリエチレンシートによる断熱効果と、を併せ持つ。このようなシート５としては、例えば、米国リフレクティックスインク社製の「リフレクティックス」（登録商標）を用いることができる。 Sheet 5 is a material made by alternately layering multiple polyethylene sheets and multiple bubble polyethylene sheets, and then sandwiching them with aluminum foil. The aluminum foil has a heat-shielding effect that reflects radiant heat, and the bubble polyethylene sheets have an insulating effect that suppresses heat conduction. In other words, Sheet 5 combines the heat-shielding effect of the aluminum foil with the insulating effect of the bubble polyethylene sheets. For example, "Reflectix" (registered trademark) manufactured by Reflectix Inc., USA, can be used as such a Sheet 5.
アルミ箔における放射熱に対する反射率は、繊維系断熱材及び発泡プラスチック系断熱材よりも高い。したがって、リフレクティックスのようにアルミ箔を有するシート５を屋根材４の下方に配置することにより、建造物の外部と内部との間での熱移動を軽減することができ、建造物内部の温度変動を軽減することができる。これにより、建造物における快適さを向上させることができる。 The reflectivity of aluminum foil against radiant heat is higher than that of fibrous insulation materials and foamed plastic insulation materials. Therefore, by placing a sheet 5 containing aluminum foil, such as Reflectix, beneath the roofing material 4, heat transfer between the exterior and interior of the building can be reduced, thereby mitigating temperature fluctuations within the building. This improves comfort within the building.
一方で、リフレクティックスのようなシート５の厚みは１０ｍｍ以下（より具体的には、８ｍｍ程度）であり、繊維系断熱材及び発泡プラスチック系断熱材からなるボードと比較して薄く軽量である。そのため、シート５を、例えば桁行方向に隣り合うタイトフレーム３に掛け渡した部材に載置するだけでは、風等によってシート５が浮いたり飛んだりしてしまうおそれがある。 On the other hand, the thickness of sheet 5, such as Reflectix, is 10 mm or less (more specifically, about 8 mm), making it thinner and lighter compared to boards made of fibrous insulation and foamed plastic insulation. Therefore, simply placing sheet 5 on a member stretched across adjacent tight frames 3 in the longitudinal direction may cause the sheet 5 to float or fly away due to wind or other factors.
本実施形態に係るシート保持具１００は、シート５を保持するために用いられる。以下、シート保持具１００について、図２から図６を参照して詳述する。 The sheet holder 100 according to this embodiment is used to hold the sheet 5. The sheet holder 100 will be described in detail below with reference to Figures 2 to 6.
図２（ａ）は、屋根構造１を梁間方向に見た側断面図である。図３は、図２（ａ）に示すＩＩＩ－ＩＩＩ線に沿う拡大断面図である。なお、図２（ａ）では、屋根材４の図示を省略している。 Figure 2(a) is a side cross-sectional view of the roof structure 1 in the direction of the beam span. Figure 3 is an enlarged cross-sectional view along the line III-III shown in Figure 2(a). Note that the roofing material 4 is not shown in Figure 2(a).
図２（ａ）及び図３に示すように、タイトフレーム３は、桁行方向に突出するハネ部３ａを有している。シート保持具１００は、桁行方向に互いに隣り合うタイトフレーム３のハネ部３ａに引っ掛けて取り付けられる。以下において、「上方」及び「下方」は、シート保持具１００は、タイトフレーム３のハネ部３ａに取り付けた状態での鉛直上方及び鉛直下方である。 As shown in Figures 2(a) and 3, the tight frame 3 has a wing portion 3a that protrudes in the longitudinal direction. The sheet holder 100 is attached by hooking it onto the wing portions 3a of adjacent tight frames 3 in the longitudinal direction. In the following, "upper" and "lower" refer to the vertically upward and vertically downward directions when the sheet holder 100 is attached to the wing portions 3a of the tight frame 3.
シート保持具１００は、梁間方向に隣り合うシート５を下方から支持する下側部材１０と、隣り合うシート５を間に挟んで下側部材１０に重ねられる上側部材２０と、を備えている。図２（ｂ）は、下側部材１０から上側部材２０を分離した状態の屋根構造１を、図２（ａ）に対応して示す側断面図である。図２（ｂ）では、図２（ａ）と同様に、屋根材４の図示を省略している。 The sheet holder 100 comprises a lower member 10 that supports adjacent sheets 5 in the beam direction from below, and an upper member 20 that overlaps the lower member 10 with the adjacent sheets 5 sandwiched in between. Figure 2(b) is a side cross-sectional view of the roof structure 1 with the upper member 20 separated from the lower member 10, corresponding to Figure 2(a). In Figure 2(b), as in Figure 2(a), the roofing material 4 is not shown.
図３に示すように、下側部材１０は、隣り合うシート５が載置される載置部１１と、隣り合うシート５の間から上方に突出して載置部１１に設けられた突出部１２と、を有している。下側部材１０は、帯状の一枚の金属板に曲げ加工を施すことにより形成される。 As shown in Figure 3, the lower member 10 has a mounting portion 11 on which adjacent sheets 5 are placed, and a projection 12 that protrudes upward from between the adjacent sheets 5 and is provided on the mounting portion 11. The lower member 10 is formed by bending a single strip-shaped metal plate.
載置部１１は、隣り合うシート５のうちの一方のシート５が載置される第１載置部１１ａと、隣り合うシート５のうちの他方のシート５が載置される第２載置部１１ｂと、を含む。 The mounting section 11 includes a first mounting section 11a on which one of two adjacent sheets 5 is placed, and a second mounting section 11b on which the other of two adjacent sheets 5 is placed.
以下において、図３に示される２つのシート５のうち紙面左側のシート５を「左側シート５ａ」とも称し、紙面右側のシート５を「右側シート５ｂ」とも称する。また、第１載置部１１ａを「左側載置部１１ａ」とも称し、第２載置部１１ｂを「右側載置部１１ｂ」とも称する。 In the following, of the two sheets 5 shown in Figure 3, the sheet 5 on the left side of the page will also be referred to as "left sheet 5a," and the sheet 5 on the right side of the page will also be referred to as "right sheet 5b." Furthermore, the first mounting section 11a will also be referred to as "left mounting section 11a," and the second mounting section 11b will also be referred to as "right mounting section 11b."
左側載置部１１ａは、右側載置部１１ｂの下方に重ねられかつ右側載置部１１ｂから左側に延出するように、右側載置部１１ｂの右端で曲げ返されて形成される。 The left-side mounting portion 11a is formed by overlapping the right-side mounting portion 11b below it and extending to the left from the right-side mounting portion 11b, by bending the right end of the right-side mounting portion 11b.
突出部１２は、右側載置部１１ｂの左端で上方に曲げられ上方に延びる第１延在部１２ａと、第１延在部１２ａの上端で下方に曲げ返された第２延在部１２ｂと、を含む。第１延在部１２ａと第２延在部１２ｂとの間にタイトフレーム３のハネ部３ａを挿入することにより、突出部１２がタイトフレーム３に引っ掛けられる。つまり、第２延在部１２ｂは、タイトフレーム３のハネ部３ａに引っ掛け可能に第１延在部１２ａから曲げ返されている。 The protruding portion 12 includes a first extending portion 12a that is bent upward at the left end of the right-side mounting portion 11b and extends upward, and a second extending portion 12b that is bent downward at the upper end of the first extending portion 12a. By inserting the wing portion 3a of the tight frame 3 between the first extending portion 12a and the second extending portion 12b, the protruding portion 12 is hooked onto the tight frame 3. In other words, the second extending portion 12b is bent back from the first extending portion 12a so that it can be hooked onto the wing portion 3a of the tight frame 3.
第２延在部１２ｂは、詳細には、上下方向における異なる２か所で１０°～５０°程度で曲げられている。第２延在部１２ｂの上端１２ｃと、上側の曲げ部１２ｄと、の間の部分は、下方に向かうにつれて第１延在部１２ａから離れるように第１延在部１２ａに対して傾斜している。上側の曲げ部１２ｄと下側の曲げ部１２ｅとの間の部分は、下方に向かうにつれて第１延在部１２ａに近づくように第１延在部１２ａに対して傾斜している。下側の曲げ部１２ｅと下端１２ｆとの間の部分は、下方に向かうにつれて第１延在部１２ａから離れるように第１延在部１２ａに対して傾斜している。 The second extension portion 12b is bent at two different points in the vertical direction at an angle of approximately 10° to 50°. The portion between the upper end 12c of the second extension portion 12b and the upper bent portion 12d is inclined with respect to the first extension portion 12a, moving away from it as it extends downwards. The portion between the upper bent portion 12d and the lower bent portion 12e is inclined with respect to the first extension portion 12a, moving closer to it as it extends downwards. The portion between the lower bent portion 12e and the lower end 12f is inclined with respect to the first extension portion 12a, moving away from it as it extends downwards.
下側の曲げ部１２ｅと下端１２ｆとの間の部分が上記のように傾斜しているため、タイトフレーム３のハネ部３ａを下方から第１延在部１２ａと第２延在部１２ｂとの間に容易に挿入することができる。また、上端１２ｃと上側の曲げ部１２ｄとの間の部分が上記のように傾斜しているため、ハネ部３ａに突出部１２が引っ掛けられた状態では、梁間方向への突出部１２の動きをハネ部３ａにより規制することができる。 Because the portion between the lower bent portion 12e and the lower end 12f is inclined as described above, the wing portion 3a of the tight frame 3 can be easily inserted from below between the first extended portion 12a and the second extended portion 12b. Furthermore, because the portion between the upper end 12c and the upper bent portion 12d is inclined as described above, when the protruding portion 12 is hooked onto the wing portion 3a, the movement of the protruding portion 12 in the beam direction can be restricted by the wing portion 3a.
上側部材２０は、下側部材１０の突出部１２を受入れ可能な形状に形成されている。具体的には、上側部材２０は、突出部１２を下方から受入れる断面略逆Ｖ字状の受入部２１と、受入部２１の一方の下端から外側に出る第１庇部２２ａと、受入部２１の他方の下端から外側に出る第２庇部２２ｂと、を有している。上側部材２０は、下側部材１０と同様に、帯状の一枚の金属板に曲げ加工を施すことにより形成される。 The upper member 20 is formed in a shape capable of receiving the protrusion 12 of the lower member 10. Specifically, the upper member 20 has a receiving portion 21 with a substantially inverted V-shaped cross-section that receives the protrusion 12 from below, a first overhang portion 22a extending outward from one lower end of the receiving portion 21, and a second overhang portion 22b extending outward from the other lower end of the receiving portion 21. The upper member 20, like the lower member 10, is formed by bending a single strip of metal sheet.
以下において、下側部材１０と同様に、図３に示される受入部２１の２つの下端のうち紙面左側の下端を「左下端」とし、紙面右側の下端を「右下端」とする。また、第１庇部２２ａを「左側庇部２２ａ」とも称し、第２庇部２２ｂを「右側庇部２２ｂ」とも称する。 In the following, similar to the lower member 10, the lower end on the left side of the paper of the receiving portion 21 shown in Figure 3 will be referred to as the "left lower end," and the lower end on the right side of the paper will be referred to as the "right lower end." Furthermore, the first visor portion 22a will also be referred to as the "left visor portion 22a," and the second visor portion 22b will also be referred to as the "right visor portion 22b."
受入部２１は、間に突出部１２の第２延在部１２ｂを受入れ可能に配置された第１側壁部２１ａ及び第２側壁部２１ｂを有している。上側部材２０は、第１側壁部２１ａが突出部１２の第１延在部１２ａに対して第２延在部１２ｂとは反対側に位置するように下側部材１０に重ねられる。第１側壁部２１ａは、受入部２１の頂部２１ｅと左側庇部２２ａとの間に渡って略直線状に延びている。 The receiving portion 21 has a first side wall portion 21a and a second side wall portion 21b, which are positioned to receive the second extended portion 12b of the protruding portion 12. The upper member 20 is superimposed on the lower member 10 such that the first side wall portion 21a is located on the opposite side of the second extended portion 12b from the first extended portion 12a of the protruding portion 12. The first side wall portion 21a extends in a substantially straight line between the top portion 21e of the receiving portion 21 and the left-side overhang portion 22a.
また、受入部２１は、第２側壁部２１ｂから第１側壁部２１ａに向かって突出し括れを形成する括れ部２１ｃと、括れ部２１ｃと右側庇部２２ｂとの間に渡って設けられる第３側壁部２１ｄと、を有している。上側部材２０が下側部材１０に重ねられた状態では、括れ部２１ｃは、突出部１２の第２延在部１２ｂの下方に位置する。つまり、第２延在部１２ｂは、第１側壁部２１ａと第２側壁部２１ｂとの間にのみ配置され、第１側壁部２１ａと第３側壁部２１ｄとの間には配置されない。 Furthermore, the receiving portion 21 has a constricted portion 21c that protrudes from the second side wall portion 21b toward the first side wall portion 21a, forming a constriction, and a third side wall portion 21d that extends between the constricted portion 21c and the right-side overhang portion 22b. When the upper member 20 is superimposed on the lower member 10, the constricted portion 21c is located below the second extended portion 12b of the protruding portion 12. In other words, the second extended portion 12b is positioned only between the first side wall portion 21a and the second side wall portion 21b, and not between the first side wall portion 21a and the third side wall portion 21d.
突出部１２の第２延在部１２ｂは、左側シート５ａ及び右側シート５ｂを間に挟んで上側部材２０を下側部材１０に重ねた状態において括れ部２１ｃを下方に付勢するように形成されている。そのため、上側部材２０の左側庇部２２ａが左側シート５ａに押付けられ、上側部材２０の右側庇部２２ｂが右側シート５ｂに押付けられる。その結果、左側シート５ａが下側部材１０の左側載置部１１ａに押付けられ、右側シート５ｂが下側部材１０の右側載置部１１ｂに押付けられる。 The second extended portion 12b of the protruding portion 12 is formed to bias the constricted portion 21c downward when the upper member 20 is superimposed on the lower member 10 with the left sheet 5a and the right sheet 5b sandwiched between them. Therefore, the left overhang portion 22a of the upper member 20 is pressed against the left sheet 5a, and the right overhang portion 22b of the upper member 20 is pressed against the right sheet 5b. As a result, the left sheet 5a is pressed against the left mounting portion 11a of the lower member 10, and the right sheet 5b is pressed against the right mounting portion 11b of the lower member 10.
このように、上側部材２０の受入部２１が下側部材１０の突出部１２を受入れた状態において、突出部１２は、上側部材２０を介して左側シート５ａ及び右側シート５ｂを下側部材１０の左側載置部１１ａ及び右側載置部１１ｂにそれぞれ押付ける。そのため、左側シート５ａ及び右側シート５ｂは、下側部材１０と上側部材２０とによって挟持される。したがって、左側シート５ａ及び右側シート５ｂを容易に保持することができ、風等によって左側シート５ａ及び右側シート５ｂが浮いたり飛んだりすることを防ぐことができる。 In this manner, with the receiving portion 21 of the upper member 20 receiving the protruding portion 12 of the lower member 10, the protruding portion 12 presses the left sheet 5a and the right sheet 5b against the left mounting portion 11a and the right mounting portion 11b of the lower member 10, respectively, via the upper member 20. Therefore, the left sheet 5a and the right sheet 5b are held between the lower member 10 and the upper member 20. Consequently, the left sheet 5a and the right sheet 5b can be easily held, preventing them from floating or flying away due to wind or other factors.
突出部１２は、タイトフレーム３のハネ部３ａに引っ掛け可能に第１延在部１２ａから曲げ返された第２延在部１２ｂを有しており、第２延在部１２ｂが、上側部材２０を介して左側シート５ａ及び右側シート５ｂを下側部材１０の載置部１１に押付ける。そのため、第２延在部１２ｂは、ハネ部３ａへ引っ掛けられる機能と、下側部材１０の載置部１１へ左側シート５ａ及び右側シート５ｂを押し付ける機能と、を有することになる。したがって、下側部材１０の形状を簡素化しつつ左側シート５ａ及び右側シート５ｂを容易に保持することができる。 The protruding portion 12 has a second extending portion 12b that is bent back from the first extending portion 12a so as to be hookable onto the wing portion 3a of the tight frame 3. The second extending portion 12b presses the left sheet 5a and the right sheet 5b against the mounting portion 11 of the lower member 10 via the upper member 20. Therefore, the second extending portion 12b has the function of hooking onto the wing portion 3a and the function of pressing the left sheet 5a and the right sheet 5b against the mounting portion 11 of the lower member 10. Thus, the shape of the lower member 10 can be simplified while easily holding the left sheet 5a and the right sheet 5b.
第３側壁部２１ｄは、下方に向かうにつれて第１側壁部２１ａから離れるように第１側壁部２１ａに対して傾斜している。そのため、下側部材１０の突出部１２を下方から受入部２１に容易に挿入することができる。 The third side wall portion 21d is inclined with respect to the first side wall portion 21a so that it moves away from the first side wall portion 21a as it extends downward. Therefore, the protruding portion 12 of the lower member 10 can be easily inserted into the receiving portion 21 from below.
上側部材２０を下側部材１０に重ねる際には、上側部材２０を下側部材１０の上方から降下させ、突出部１２の上端１２ｃを受入部２１の第１側壁部２１ａと第３側壁部２１ｄとの間に挿入する。この状態から上側部材２０を降下させると、突出部１２の第２延在部１２ｂが受入部２１の第３側壁部２１ｄに接触し、第３側壁部２１ｄ、括れ部２１ｃ及び第２側壁部２１ｂが外側（図３における右側）へ押し広げられる。更に上側部材２０を降下させ括れ部２１ｃが第２延在部１２ｂを越えると、受入部２１が元の形状に戻り、括れ部２１ｃが第２延在部１２ｂの下方に移動する。その結果、第２延在部１２ｂにより、括れ部２１ｃが下方に付勢される。 When overlapping the upper member 20 with the lower member 10, the upper member 20 is lowered from above the lower member 10, and the upper end 12c of the protruding portion 12 is inserted between the first side wall portion 21a and the third side wall portion 21d of the receiving portion 21. When the upper member 20 is lowered from this position, the second extension portion 12b of the protruding portion 12 contacts the third side wall portion 21d of the receiving portion 21, and the third side wall portion 21d, the constricted portion 21c, and the second side wall portion 21b are pushed outward (to the right in Figure 3). Further lowering the upper member 20 causes the constricted portion 21c to exceed the second extension portion 12b, causing the receiving portion 21 to return to its original shape, and the constricted portion 21c to move below the second extension portion 12b. As a result, the constricted portion 21c is biased downward by the second extension portion 12b.
上側部材２０の括れ部２１ｃは、上側部材２０を下側部材１０に重ねた状態において、タイトフレーム３のハネ部３ａの下方において突出部１２の第１延在部１２ａと第２延在部１２ｂとの間を塞ぐ。そのため、ハネ部３ａは、上側部材２０を下側部材１０に重ねた状態では、第１延在部１２ａと第２延在部１２ｂとの間から抜け出なくなる。したがって、左側シート５ａ及び右側シート５ｂが風等を受けても、下側部材１０がハネ部３ａから外れることを防ぐことができる。 The constricted portion 21c of the upper member 20 closes the space between the first extended portion 12a and the second extended portion 12b of the protruding portion 12 below the wing portion 3a of the tight frame 3 when the upper member 20 is superimposed on the lower member 10. Therefore, when the upper member 20 is superimposed on the lower member 10, the wing portion 3a cannot slip out from between the first extended portion 12a and the second extended portion 12b. Consequently, even if the left sheet 5a and the right sheet 5b are subjected to wind or other forces, the lower member 10 can be prevented from detaching from the wing portion 3a.
なお、上側部材２０の括れ部２１ｃは、上側部材２０を下側部材１０に重ねた状態において、突出部１２の第１延在部１２ａに接触している必要はない。例えば、タイトフレーム３のハネ部３ａが抜け出ない程度の隙間が第１延在部１２ａと括れ部２１ｃとの間に形成されていてもよい。 Furthermore, the constricted portion 21c of the upper member 20 does not need to be in contact with the first extended portion 12a of the protruding portion 12 when the upper member 20 is superimposed on the lower member 10. For example, a gap sufficient to prevent the wing portion 3a of the tight frame 3 from slipping out may be formed between the first extended portion 12a and the constricted portion 21c.
次に、屋根構造１の構築方法について、図４～図６を参照して説明する。図４（ａ）及び（ｂ）は、構築方法を説明するための図である。本実施形態に係る構築方法では、図４に示す複数のシートユニット５０が用いられる。図５は、図４（ａ）に示すＶ部の拡大図であり、図６は、図４（ａ）に示すＶＩ部の拡大図である。 Next, the construction method of the roof structure 1 will be explained with reference to Figures 4 to 6. Figures 4(a) and 4(b) are diagrams illustrating the construction method. In the construction method according to this embodiment, a plurality of sheet units 50 shown in Figure 4 are used. Figure 5 is an enlarged view of section V shown in Figure 4(a), and Figure 6 is an enlarged view of section VI shown in Figure 4(a).
図４に示すように、シートユニット５０は、シート５と、一のシート保持具１００における下側部材１０と、別のシート保持具１００における上側部材２０と、を備える。図５に示すように、下側部材１０は、シート５の左端近傍に配置されており、下側部材１０の右側載置部１１ｂにシート５の左端近傍が載置されている。シート５と下側部材１０とは例えば両面テープを用いて互いに固定又は接着されていてもよい。 As shown in Figure 4, the sheet unit 50 comprises a sheet 5, a lower member 10 of one sheet holder 100, and an upper member 20 of another sheet holder 100. As shown in Figure 5, the lower member 10 is positioned near the left edge of the sheet 5, and the area near the left edge of the sheet 5 is placed on the right-side mounting portion 11b of the lower member 10. The sheet 5 and the lower member 10 may be fixed or bonded to each other, for example, using double-sided tape.
図６に示すように、上側部材２０は、シート５の右端近傍に配置されており、上側部材２０の左側庇部２２ａに固定されている。シート５と左側庇部２２ａとの固定には、例えば、両面テープを用いることができる。 As shown in Figure 6, the upper member 20 is positioned near the right edge of the sheet 5 and is fixed to the left visor portion 22a of the upper member 20. For example, double-sided tape can be used to fix the sheet 5 to the left visor portion 22a.
本実施形態に係る構築方法では、複数のシートユニット５０を順に梁間方向に並べて配置することにより、屋根構造１を構築する。以下では、配置済みのシートユニット５０の隣に新たにシートユニット５０を配置する手順について説明する。図４（ａ）において、紙面右側に示されるシートユニット５０を、下側部材１０がタイトフレーム３のハネ部３ａ（図２等参照）に引っ掛けられた配置済みのシートユニット５０とし、「右側シートユニット５１」とも称する。紙面左側に示されるシートユニット５０を、新たに配置されるシートユニット５０とし、「左側シートユニット５２」とも称する。 In the construction method according to this embodiment, the roof structure 1 is constructed by arranging multiple sheet units 50 sequentially in the direction of the beams. The following describes the procedure for arranging a new sheet unit 50 next to an already arranged sheet unit 50. In Figure 4(a), the sheet unit 50 shown on the right side of the page is an already arranged sheet unit 50 whose lower member 10 is hooked onto the wing portion 3a of the tight frame 3 (see Figure 2, etc.), and is also referred to as the "right sheet unit 51". The sheet unit 50 shown on the left side of the page is a newly arranged sheet unit 50, and is also referred to as the "left sheet unit 52".
まず、図４（ａ）に示すように、右側シートユニット５１における下側部材１０の上方に左側シートユニット５２における上側部材２０が来るように左側シートユニット５２を移動させる。次に、左側シートユニット５２を降下させる。これにより、右側シートユニット５１における下側部材１０の突出部１２が左側シートユニット５２における上側部材２０の受入部２１に挿入され、左側シートユニット５２における上側部材２０が右側シートユニット５１における下側部材１０に重ねられる。また、左側シートユニット５２における下側部材１０の突出部１２がタイトフレーム３のハネ部３ａに引っ掛けられる。 First, as shown in Figure 4(a), the left seat unit 52 is moved so that the upper member 20 of the left seat unit 52 is above the lower member 10 of the right seat unit 51. Next, the left seat unit 52 is lowered. As a result, the protruding portion 12 of the lower member 10 of the right seat unit 51 is inserted into the receiving portion 21 of the upper member 20 of the left seat unit 52, and the upper member 20 of the left seat unit 52 is superimposed on the lower member 10 of the right seat unit 51. Also, the protruding portion 12 of the lower member 10 of the left seat unit 52 is hooked onto the wing portion 3a of the tight frame 3.
図４（ｂ）に示すように、左側シートユニット５２における上側部材２０の括れ部２１ｃが右側シートユニット５１における下側部材１０の第２延在部１２ｂを越えるまで左側シートユニット５２を降下させると、左側シートユニット５２におけるシート５は、右側シートユニット５１における下側部材１０の載置部１１に載置される。また、右側シートユニット５１における下側部材１０の突出部１２は、右側シートユニット５１におけるシート５と左側シートユニット５２におけるシート５との間から上方に突出する。右側シートユニット５１における下側部材１０の突出部１２は、左側シートユニット５２における上側部材２０を介して、右側シートユニット５１におけるシート５と左側シートユニット５２におけるシート５を右側シートユニット５１における下側部材１０の載置部１１に押付ける。その結果、右側シートユニット５１におけるシート５と左側シートユニット５２におけるシート５とが、右側シートユニット５１における下側部材１０と左側シートユニット５２における上側部材２０とにより挟持される。 As shown in Figure 4(b), when the left seat unit 52 is lowered until the constricted portion 21c of the upper member 20 of the left seat unit 52 exceeds the second extended portion 12b of the lower member 10 of the right seat unit 51, the seat 5 of the left seat unit 52 is placed on the mounting portion 11 of the lower member 10 of the right seat unit 51. Also, the protruding portion 12 of the lower member 10 of the right seat unit 51 protrudes upward from between the seat 5 of the right seat unit 51 and the seat 5 of the left seat unit 52. The protruding portion 12 of the lower member 10 of the right seat unit 51 presses the seat 5 of the right seat unit 51 and the seat 5 of the left seat unit 52 against the mounting portion 11 of the lower member 10 of the right seat unit 51 via the upper member 20 of the left seat unit 52. As a result, the seat 5 in the right-side seat unit 51 and the seat 5 in the left-side seat unit 52 are sandwiched between the lower member 10 of the right-side seat unit 51 and the upper member 20 of the left-side seat unit 52.
左側シートユニット５２におけるシート５は、更に別のシートユニット５３における上側部材２０を左側シートユニット５２における下側部材１０に重ねることにより、左側シートユニット５２における下側部材１０の載置部１１に押付けられる。 The seat 5 in the left seat unit 52 is pressed against the mounting portion 11 of the lower member 10 of the left seat unit 52 by overlapping the upper member 20 of another seat unit 53 with the lower member 10 of the left seat unit 52.
このように、本実施形態によれば、隣り合うシート５が順に下側部材１０と上側部材２０とにより挟持される。したがって、シート５と下側部材１０との固定力（接着力）、及びシート５と上側部材２０との固定力（接着力）が弱くても、風等によってシート５が浮いたり飛んだりすることを防ぐことができる。 Thus, according to this embodiment, adjacent sheets 5 are sequentially sandwiched between the lower member 10 and the upper member 20. Therefore, even if the fixing force (adhesive force) between the sheet 5 and the lower member 10, and the fixing force (adhesive force) between the sheet 5 and the upper member 20 are weak, it is possible to prevent the sheets 5 from floating or flying away due to wind or other factors.
なお、シートユニット５０の配置時には、作業員がシート５、下側部材１０及び上側部材２０を持つことになるため、風等によってシート５が飛ぶことはない。 Furthermore, when the sheet unit 50 is positioned, the worker will be holding the sheet 5, the lower member 10, and the upper member 20, so the sheet 5 will not be blown away by wind or other factors.
以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 Although embodiments of the present invention have been described above, these embodiments represent only a portion of the applications of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.
図７は、変形例に係る屋根構造１の構築方法を説明するための図である。上記実施形態では図４に示すように、シールユニット５０を組み立てて順に並べて配置することにより、屋根構造１を構築している。変形例は、シールユニット５０を組み立てることなく屋根構造１を構築する。 Figure 7 illustrates a modified example of how to construct the roof structure 1. In the above embodiment, as shown in Figure 4, the roof structure 1 is constructed by assembling and arranging the seal units 50 in sequence. The modified example constructs the roof structure 1 without assembling the seal units 50.
図７（ａ）に示すように、タイトフレーム３のハネ部３ａに引っ掛けられた下側部材１０に、２枚のシート５を載置する。このとき、下側部材１０の突出部１２を、隣り合うシート５の間から突出させる。次に、下側部材１０の上方から上側部材２０を降下させる。これにより、下側部材１０の突出部１２が上側部材２０の受入部２１に挿入され、上側部材２０が下側部材１０に重ねられる。 As shown in Figure 7(a), two sheets 5 are placed on the lower member 10, which is hooked onto the wing portion 3a of the tight frame 3. At this time, the protruding portion 12 of the lower member 10 is made to protrude from between the adjacent sheets 5. Next, the upper member 20 is lowered from above the lower member 10. This causes the protruding portion 12 of the lower member 10 to be inserted into the receiving portion 21 of the upper member 20, and the upper member 20 is placed on top of the lower member 10.
図７（ｂ）に示すように、上側部材２０の括れ部２１ｃが下側部材１０の第２延在部１２ｂを越えるまで上側部材２０を降下させると、下側部材１０の突出部１２は、上側部材２０を介して、隣り合うシート５を下側部材１０の載置部１１に押付ける。その結果、隣り合うシート５が下側部材１０と上側部材２０とにより挟持される。 As shown in Figure 7(b), when the upper member 20 is lowered until the constricted portion 21c of the upper member 20 exceeds the second extended portion 12b of the lower member 10, the protruding portion 12 of the lower member 10 presses the adjacent sheets 5 against the mounting portion 11 of the lower member 10 via the upper member 20. As a result, the adjacent sheets 5 are sandwiched between the lower member 10 and the upper member 20.
このように、変形例であっても、上側部材２０を下側部材１０に重ねるだけで、隣り合うシート５が下側部材１０と上側部材２０とにより挟持される。したがって、隣り合うシート５を容易に保持することができ、風等によってシート５が浮いたり飛んだりすることを防ぐことができる。 Thus, even in this modified configuration, simply overlapping the upper member 20 with the lower member 10 allows adjacent sheets 5 to be sandwiched between the lower member 10 and the upper member 20. Therefore, adjacent sheets 5 can be easily held in place, preventing them from floating or flying away due to wind or other factors.
上記実施形態及び変形例では、梁間方向に互いに隣り合うシート５を保持するシート保持具１００について説明したが、シート保持具１００は、桁行方向に互いに隣り合うシート５を保持してもよい。つまり、本発明は、屋根材４の下方において互いに横方向に隣り合うシート５の保持に適用可能である。 In the above embodiments and modifications, a sheet holder 100 was described for holding sheets 5 adjacent to each other in the beam direction. However, the sheet holder 100 may also hold sheets 5 adjacent to each other in the girder direction. In other words, the present invention is applicable to holding sheets 5 adjacent to each other in the lateral direction below the roofing material 4.
また、上記実施形態及び変形例では、シート５がリフレクティックスのような遮熱シートである場合について説明したが、シート５は遮熱シートに限られず、例えば断熱シートであってもよい。 Furthermore, while the above embodiments and modifications described a case where sheet 5 is a heat-shielding sheet such as Reflectix, sheet 5 is not limited to a heat-shielding sheet; for example, it may be an insulating sheet.
上記実施形態及び変形例では、タイトフレーム３のハネ部３ａに下側部材１０の突出部１２に引っ掛ける場合について説明したが、突出部１２は、例えば梁２に引っ掛けられてもよい。つまり、第２延在部１２ｂは、屋根材４を支持する支持構造体に引っ掛け可能に第１延在部１２ａから曲げ返されていればよい。 In the above embodiments and modifications, the case in which the protruding portion 12 of the lower member 10 is hooked onto the wing portion 3a of the tight frame 3 was described. However, the protruding portion 12 may be hooked onto, for example, the beam 2. In other words, the second extending portion 12b only needs to be bent back from the first extending portion 12a so that it can be hooked onto the support structure that supports the roofing material 4.
