Description

本発明は、複数本の鉄骨を連結具により連結して構成される梁と、その鉄骨連結箇所の上方に配置支持される保持部材と、その保持部材と前記梁の上方に配置支持されるタイトフレームを備え、そのタイトフレームの上面に載置される折板製の屋根を支持する屋根の支持構造に関する。 In the present invention, a beam configured by connecting a plurality of steel frames by a connecting tool, a holding member arranged and supported above the steel frame connecting portion, and a tight placed and supported above the holding member and the beam. It relates to a roof support structure comprising a frame and supporting a folded plate roof mounted on the upper surface of the tight frame.

このような屋根の支持構造では、複数本の鉄骨をボルト・ナットなどの連結具により連結して梁を構成するため、その鉄骨連結箇所においては、ボルトの頭またはナットなどが梁の上面から上方へ突出し、タイトフレームを梁の上面に直接載置して支持することが困難となる。そこで、従来では、鉄骨連結箇所を除く梁の上面に型鋼製の嵩上げ部材などを接続し、金属製の平板からなる保持部材を鉄骨連結箇所の両側に位置する嵩上げ部材の間に亘って配置接続して、タイトフレームを嵩上げ部材と保持部材の上面に載置して支持するのが一般的であった（例えば、特許文献１の図７参照）。 In such a roof support structure, a plurality of steel frames are connected by connecting tools such as bolts and nuts to form a beam. Therefore, at the steel frame connecting points, the head or nut of the bolt is above the upper surface of the beam. It is difficult to support the tight frame by placing it directly on the upper surface of the beam. Therefore, conventionally, a steel frame raising member or the like is connected to the upper surface of the beam excluding the steel frame connecting portion, and a holding member made of a metal flat plate is arranged between the raising members located on both sides of the steel frame connecting portion. It was common to connect and support the tight frame by placing it on the upper surface of the raising member and the holding member (see, for example, FIG. 7 of Patent Document 1).

しかし、嵩上げ部材間に亘って配置接続される保持部材は、通常、軽量ではあるが比較的強度的に弱い金属製の平板などが使用されるため、例えば、屋根に風圧が作用すると、保持部材が上下方向へ繰り返し湾曲移動し、いわゆるバタつきを生じ、折板製の屋根全体が風圧によってバタつきを生じることになる。
そこで、従来、平板からなる保持部材を強固な補強部材で補強するか、あるいは、平板製の保持部材に代えて、例えば、断面「コ」の字状の型鋼を背中合わせに接合して構成される強固な部材などを使用し、その強固な部材を鉄骨連結箇所の両側に位置する嵩上げ部材の間に亘って配置して対処していたのが実情である（例えば、特許文献１の図１～図６参照）。 However, as the holding member that is arranged and connected between the raising members, a metal flat plate that is lightweight but relatively weak in strength is usually used. Therefore, for example, when wind pressure acts on the roof, the holding member Will repeatedly bend and move in the vertical direction, causing so-called fluttering, and the entire folded-plate roof will flutter due to wind pressure.
Therefore, conventionally, the holding member made of a flat plate is reinforced with a strong reinforcing member, or instead of the holding member made of a flat plate, for example, a steel frame having a "U" cross section is joined back to back. The actual situation is that a strong member or the like is used and the strong member is arranged between the raised members located on both sides of the steel frame connecting portion to deal with the problem (for example, FIGS. 1 to 1 of Patent Document 1). See FIG. 6).

特開２００５－１４６７１０号公報Japanese Unexamined Patent Publication No. 2005-146710

しかしながら、平板により保持部材を構成する場合には、平板製の保持部材を強固な補強材で補強する必要があり、また、上記特許文献に記載のように、平板製の保持部材に代えて強固な部材を使用する場合には、保持部材そのものを強固な構造にする必要があるなど、いずれにせよ、比較的重くて大掛かりな構造となる欠点があった。 However, when the holding member is made of a flat plate, it is necessary to reinforce the holding member made of the flat plate with a strong reinforcing material, and as described in the above patent document, it is strong instead of the holding member made of the flat plate. In any case, there is a drawback that the holding member itself has a relatively heavy and large-scale structure, for example, when a simple member is used, the holding member itself needs to have a strong structure.

本発明は、このような従来の問題点に着目したもので、その目的は、たとえ比較的軽量で強度的に弱い金属製の平板により保持部材を構成する場合であっても、特に強固な補強材を必要とすることなく、風圧による屋根のバタつきなどを抑制することの可能な屋根の支持構造を提供することにある。 The present invention focuses on such conventional problems, and an object thereof is particularly strong reinforcement even when the holding member is made of a metal flat plate which is relatively lightweight and weak in strength. It is an object of the present invention to provide a roof support structure capable of suppressing roof fluttering due to wind pressure without the need for materials.

本発明の第１特徴構成は、複数本の鉄骨を連結具により連結して構成される梁と、その鉄骨連結箇所の上方に配置支持される保持部材と、その保持部材と前記梁の上方に配置支持されるタイトフレームを備え、そのタイトフレームの上面に載置される折板製の屋根を支持する屋根の支持構造であって、前記保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成され、前記鉄骨連結箇所を除く前記梁の上面に載置支持される嵩上げ部材を備え、前記保持部材の両端部が、前記鉄骨連結箇所の両側に位置する前記嵩上げ部材に接続され、前記タイトフレームが、前記嵩上げ部材と保持部材の上面に載置支持される点にある。 The first characteristic configuration of the present invention is a beam configured by connecting a plurality of steel frames by a connecting tool, a holding member arranged and supported above the steel frame connecting portion, and above the holding member and the beam. A roof support structure comprising a tight frame to be placed and supported and supporting a folded plate roof mounted on the upper surface of the tight frame, wherein the holding member is upward from both ends thereof toward the center. The raising member is provided in a shape that bulges to, and is mounted and supported on the upper surface of the beam except for the steel frame connecting portion, and both ends of the holding member are located on both sides of the steel frame connecting portion. The tight frame is placed and supported on the upper surfaces of the raising member and the holding member .

本構成によれば、梁の鉄骨連結箇所の上方に配置支持される保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成されるので、つまり、保持部材を予め積極的にたわませておくので、屋根に風圧が作用した際、その風圧作用の初期段階から、保持部材には、風圧に対抗し得るだけの張力が生じることになる。
したがって、たとえ金属製の平板により保持部材を構成する場合であっても、強固な補強材などで補強する必要もなく、保持部材を上方へ膨出させるだけの簡単かつ軽量な構成で、予想される風圧に初期段階から十分に対抗して、例えば、風圧による保持部材や折板製の屋根のバタつきなどを抑制することができる。 According to this configuration, the holding member arranged and supported above the steel frame connecting portion of the beam is configured to bulge upward from both ends thereof toward the center, that is, the holding member is positively pressed in advance. Therefore, when the wind pressure acts on the roof, the holding member is tensioned enough to counter the wind pressure from the initial stage of the wind pressure action.
Therefore, even if the holding member is constructed of a metal flat plate, it is not necessary to reinforce it with a strong reinforcing material or the like, and it is expected that the holding member will have a simple and lightweight structure that only bulges upward. It is possible to sufficiently counteract the wind pressure from the initial stage, for example, to suppress the fluttering of the holding member and the roof made of folded plate due to the wind pressure.

本構成によれば、鉄骨連結箇所を除く梁の上面に載置支持される嵩上げ部材を備え、保持部材の両端部が、鉄骨連結箇所の両側に位置する嵩上げ部材に接続されるので、保持部材は、嵩上げされた分だけ上方に位置し、鉄骨を連結する連結具と干渉することなくその上方を跨ぐことが容易となる。
したがって、保持部材に関しては、主として上方へ膨出する形状のみを考慮して小型かつ軽量化することができ、タイトフレームは、その嵩上げ部材と保持部材の上面に載置支持される。 According to this configuration, a raising member is provided on the upper surface of the beam excluding the steel frame connecting portion, and both ends of the holding member are connected to the raising members located on both sides of the steel frame connecting portion. Is located above by the amount raised, and it becomes easy to straddle the upper part without interfering with the connecting tool connecting the steel frames.
Therefore, the holding member can be made smaller and lighter mainly in consideration of only the shape that bulges upward, and the tight frame is placed and supported on the raised member and the upper surface of the holding member.

本発明の第２特徴構成は、複数本の鉄骨を連結具により連結して構成される梁と、その鉄骨連結箇所の上方に配置支持される保持部材と、その保持部材と前記梁の上方に配置支持されるタイトフレームを備え、そのタイトフレームの上面に載置される折板製の屋根を支持する屋根の支持構造であって、前記保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成され、前記保持部材の両端部が、前記梁の上面に載置接続され、前記タイトフレームが、前記梁と保持部材の上面に載置支持される点にある。 The second characteristic configuration of the present invention is a beam configured by connecting a plurality of steel frames by a connecting tool, a holding member arranged and supported above the steel frame connecting portion, and above the holding member and the beam. A roof support structure comprising a tight frame to be placed and supported and supporting a folded plate roof mounted on the upper surface of the tight frame, wherein the holding member is upward from both ends thereof toward the center. Both ends of the holding member are mounted and connected to the upper surface of the beam, and the tight frame is mounted and supported on the upper surface of the beam and the holding member.

本構成によれば、梁の鉄骨連結箇所の上方に配置支持される保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成されるので、つまり、保持部材を予め積極的にたわませておくので、屋根に風圧が作用した際、その風圧作用の初期段階から、保持部材には、風圧に対抗し得るだけの張力が生じることになる。
したがって、たとえ金属製の平板により保持部材を構成する場合であっても、強固な補強材などで補強する必要もなく、保持部材を上方へ膨出させるだけの簡単かつ軽量な構成で、予想される風圧に初期段階から十分に対抗して、例えば、風圧による保持部材や折板製の屋根のバタつきなどを抑制することができる。
更に、本構成によれば、保持部材の両端部が、梁の上面に載置接続され、タイトフレームが、梁と保持部材の上面に載置支持されるので、上方へ膨出する保持部材の形状を有効に利用して連結具との干渉を回避しながら、上述した嵩上げ部材を使用することなく、タイトフレームを梁と保持部材に直接支持させることができる。その結果、連結具との干渉を回避しながらタイトフレームを所望どおりに支持できるのに加えて、部品点数の削減による施工費の低廉化と更なる軽量化が可能となる。 According to this configuration, the holding member arranged and supported above the steel frame connecting portion of the beam is configured to bulge upward from both ends thereof toward the center, that is, the holding member is positively pressed in advance. Therefore, when the wind pressure acts on the roof, the holding member is tensioned enough to counter the wind pressure from the initial stage of the wind pressure action.
Therefore, even if the holding member is constructed of a metal flat plate, it is not necessary to reinforce it with a strong reinforcing material or the like, and it is expected that the holding member will have a simple and lightweight structure that only bulges upward. It is possible to sufficiently counteract the wind pressure from the initial stage, for example, to suppress the fluttering of the holding member and the roof made of folded plate due to the wind pressure.
Further, according to this configuration, both ends of the holding member are mounted and connected to the upper surface of the beam, and the tight frame is mounted and supported on the upper surface of the beam and the holding member, so that the holding member bulges upward. The tight frame can be directly supported by the beam and the holding member without using the above-mentioned raising member while effectively utilizing the shape and avoiding interference with the connecting tool. As a result, in addition to being able to support the tight frame as desired while avoiding interference with the connector, it is possible to reduce the construction cost and further reduce the weight by reducing the number of parts.

本発明の第３特徴構成は、複数本の鉄骨を連結具により連結して構成される梁と、その鉄骨連結箇所の上方に配置支持される保持部材と、その保持部材と前記梁の上方に配置支持されるタイトフレームを備え、そのタイトフレームの上面に載置される折板製の屋根を支持する屋根の支持構造であって、前記保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成され、前記タイトフレームにおいて、前記保持部材の上方に配置される保持部材対応部位が、他の部位と別体に構成される点にある。 The third characteristic configuration of the present invention is a beam configured by connecting a plurality of steel frames by a connecting tool, a holding member arranged and supported above the steel frame connecting portion, and above the holding member and the beam. A roof support structure comprising a tight frame to be placed and supported and supporting a folded plate roof mounted on the upper surface of the tight frame, wherein the holding member is upward from both ends thereof toward the center. In the tight frame, the holding member corresponding portion arranged above the holding member is configured to be separate from other portions.

本構成によれば、梁の鉄骨連結箇所の上方に配置支持される保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成されるので、つまり、保持部材を予め積極的にたわませておくので、屋根に風圧が作用した際、その風圧作用の初期段階から、保持部材には、風圧に対抗し得るだけの張力が生じることになる。
したがって、たとえ金属製の平板により保持部材を構成する場合であっても、強固な補強材などで補強する必要もなく、保持部材を上方へ膨出させるだけの簡単かつ軽量な構成で、予想される風圧に初期段階から十分に対抗して、例えば、風圧による保持部材や折板製の屋根のバタつきなどを抑制することができる。
更に、本構成によれば、保持部材の上方に配置されるタイトフレームの保持部材対応部位が、他の部位と別体に構成されるので、例えば、保持部材対応部位以外の他の部位を市販のタイトフレームをそのまま使用して構成することができるとともに、保持部材対応部位のみを予め作製しておくことも、また、その保持部材対応部位と保持部材とを互いに接続した状態で予め作製しておくことも可能で、それにより施工の容易化と施工時間の短縮化を図ることができる。 According to this configuration, the holding member arranged and supported above the steel frame connecting portion of the beam is configured to bulge upward from both ends thereof toward the center, that is, the holding member is positively pressed in advance. Therefore, when the wind pressure acts on the roof, the holding member is tensioned enough to counter the wind pressure from the initial stage of the wind pressure action.
Therefore, even if the holding member is constructed of a metal flat plate, it is not necessary to reinforce it with a strong reinforcing material or the like, and it is expected that the holding member will have a simple and lightweight structure that only bulges upward. It is possible to sufficiently counteract the wind pressure from the initial stage, for example, to suppress the fluttering of the holding member and the roof made of folded plate due to the wind pressure.
Further, according to this configuration, the holding member-corresponding part of the tight frame arranged above the holding member is configured separately from the other parts. Therefore, for example, other parts other than the holding member-corresponding part are commercially available. The tight frame can be used as it is, and only the holding member corresponding part can be prepared in advance, or the holding member corresponding part and the holding member can be made in advance in a state of being connected to each other. It is also possible to keep it, which makes it possible to facilitate the construction and shorten the construction time.

本発明の第４特徴構成は、複数本の鉄骨を連結具により連結して構成される梁と、その鉄骨連結箇所の上方に配置支持される保持部材と、その保持部材と前記梁の上方に配置支持されるタイトフレームを備え、そのタイトフレームの上面に載置される折板製の屋根を支持する屋根の支持構造であって、前記保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成され、前記タイトフレームにおいて、前記保持部材の上方に配置される保持部材対応部位の上下方向高さが、他の部位の上下方向高さより低く設定されて、
前記タイトフレームの山部の上面が同じレベルに構成される点にある。 The fourth characteristic configuration of the present invention is a beam configured by connecting a plurality of steel frames by a connecting tool, a holding member arranged and supported above the steel frame connecting portion, and above the holding member and the beam. A roof support structure comprising a tight frame to be placed and supported and supporting a folded plate roof mounted on the upper surface of the tight frame, wherein the holding member is upward from both ends thereof toward the center. In the tight frame, the vertical height of the holding member corresponding portion arranged above the holding member is set to be lower than the vertical height of the other parts.
The upper surface of the mountain portion of the tight frame is configured at the same level.

本構成によれば、梁の鉄骨連結箇所の上方に配置支持される保持部材が、その両端部から中央部へ向けて上方へ膨出する形状に構成されるので、つまり、保持部材を予め積極的にたわませておくので、屋根に風圧が作用した際、その風圧作用の初期段階から、保持部材には、風圧に対抗し得るだけの張力が生じることになる。
したがって、たとえ金属製の平板により保持部材を構成する場合であっても、強固な補強材などで補強する必要もなく、保持部材を上方へ膨出させるだけの簡単かつ軽量な構成で、予想される風圧に初期段階から十分に対抗して、例えば、風圧による保持部材や折板製の屋根のバタつきなどを抑制することができる。
更に、本構成によれば、タイトフレームの保持部材対応部位の上下方向高さが、他の部位の上下方向高さより低く設定されて、タイトフレームの山部の上面が同じレベルに構成されるので、保持部材が上方へ膨出する形状であるにも拘わらず、タイトフレームの山部の上面を同じレベルにして外観的に美麗な状態で折板製の屋根を支持することができる。
本発明の第５特徴構成は、前記保持部材が、その両端部から中央部へ向けて上方へ傾斜する一対の傾斜部位と、その一対の傾斜部位の間を繋ぐ中央平坦部位を備え、その中央平坦部位の上面に前記タイトフレームの谷部が載置される点にある。
本構成によれば、保持部材が、一対の傾斜部位とその間を繋ぐ中央平坦部位を備えているので、保持部材に対して所望どおりの張力作用を期待できるのに加え、その保持部材の中央平坦部位の上面にタイトフレームの谷部が載置されるので、たとえタイトフレームの谷部が中央平坦部位に対して多少ずれたとしても、中央部位が平坦であるがため、そのずれを吸収することが可能で、その結果、保持部材によりタイトフレームを合理的な形態で確実かつ強固に支持することができる。 According to this configuration, the holding member arranged and supported above the steel frame connecting portion of the beam is configured to bulge upward from both ends thereof toward the center, that is, the holding member is positively pressed in advance. Therefore, when the wind pressure acts on the roof, the holding member is tensioned enough to counter the wind pressure from the initial stage of the wind pressure action.
Therefore, even if the holding member is constructed of a metal flat plate, it is not necessary to reinforce it with a strong reinforcing material or the like, and it is expected that the holding member will have a simple and lightweight structure that only bulges upward. It is possible to sufficiently counteract the wind pressure from the initial stage, for example, to suppress the fluttering of the holding member and the roof made of folded plate due to the wind pressure.
Further, according to this configuration, the vertical height of the portion corresponding to the holding member of the tight frame is set lower than the vertical height of the other portions, and the upper surface of the mountain portion of the tight frame is configured at the same level. Despite the shape of the holding member that bulges upward, the roof made of folded plate can be supported in a state where the upper surface of the mountain portion of the tight frame is set to the same level and the appearance is beautiful.
The fifth characteristic configuration of the present invention comprises a pair of inclined portions in which the holding member inclines upward from both ends thereof toward the central portion, and a central flat portion connecting between the pair of inclined portions, the center thereof. The valley portion of the tight frame is placed on the upper surface of the flat portion.
According to this configuration, since the holding member includes a pair of inclined portions and a central flat portion connecting between them, a desired tension action can be expected on the holding member, and the central flat portion of the holding member is expected. Since the valley of the tight frame is placed on the upper surface of the part, even if the valley of the tight frame deviates slightly from the central flat part, the central part is flat, so that the deviation should be absorbed. As a result, the tight frame can be reliably and firmly supported in a reasonable form by the holding member.

(First Embodiment)
As shown in FIG. 1, the roof support structure of the present invention supports the roof 1 made of a folded plate, and as shown in FIG. 2, a beam 2 composed of a plurality of steel frames 2a and 2b and a beam. A raising member 3 mounted and supported on the upper surface of the raising member 2, a holding member 4 connected to the raising member 3, a tight frame 5 mounted and supported on the upper surface of the raising member 3 and the holding member 4 to support the roof 1, and the like. It is equipped with.
In the beam 2, for example, a plurality of steel frames 2a and 2b made of H-shaped steel abut each other at their ends, and at the abutment portion, a seam plate 8 is attached over the upper and lower flanges and the web, respectively, as a connecting tool. It is configured by connecting with a plurality of bolts and nuts 9.

嵩上げ部材３は、例えば、Ｃ型鋼で構成されてボルト・ナット９による鉄骨２ａ、２ｂの連結箇所（以下「鉄骨連結箇所」と称す）を除く梁２の上面に載置され、梁２に溶接されて支持される。
保持部材４は、例えば、金属製の平板で構成されて鉄骨連結箇所の両側に位置する嵩上げ部材３に溶接されて支持され、保持部材４の形状は、図１および図２に示すように、正面視において、その両端部から中央部へ向けて上方へ膨出する形状に構成される。すなわち、保持部材４は、その両端部から中央部へ向けて斜め上方へ延出する一対の傾斜部位４ａと、一対の傾斜部位４ａの上端部間を繋ぐ中央平坦部位４ｂを備え、更に、一対の傾斜部位４ａの下端部には、嵩上げ部材３への接続部位４ｃがそれぞれ延設され、各接続部位４ｃが、嵩上げ部材３の上面に溶接されて支持される。 The raising member 3 is placed on the upper surface of the beam 2 excluding the connecting points of the steel frames 2a and 2b by bolts and nuts 9 (hereinafter referred to as “steel frame connecting points”), which are made of C-shaped steel, and are welded to the beam 2.

In front view, it is configured to bulge upward from both ends toward the center. That is, the holding member 4 includes a pair of inclined portions 4a extending diagonally upward from both ends thereof toward the central portion, and a pair of central flat portions 4b connecting the upper ends of the pair of inclined portions 4a. At the lower end of the inclined portion 4a, connection portions 4c to the raising member 3 are extended, and each connecting portion 4c is welded to and supported on the upper surface of the raising member 3.

折板製の屋根１を支持するタイトフレーム５は、保持部材４の上方に配置される保持部材対応部位７と、保持部材対応部位７以外の他の部位６、言い換えると、嵩上げ部材３の上方に配置される通常の部位（以下「通常の部位」と称す）６からなり、両部位６、７は、図３に示すように、その谷部６ａ、７ａで分離されて互いに別体に構成される。
タイトフレーム５の通常の部位６に関しては、例えば、市販のタイトフレームをそのまま使用することも可能で、その通常の部位６の谷部６ａが、図３に示すように、嵩上げ部材３の上面に載置され、嵩上げ部材３に溶接されて支持される。
タイトフレーム５の保持部材対応部位７は、市販のタイトフレームを加工して作製され、あるいは、金属製の平板により専用に作製される。保持部材対応部位７の両端に位置する谷部７ａは、図３に示すように、保持部材４の接続部位４ｃの上面に載置され、接続部位４ｃに溶接されて支持され、中央の谷部７ａは、保持部材４の中央平坦部位４ｂの上面に載置され、中央平坦部位４ｂに溶接されて支持される。 The tight frame 5 that supports the folded plate roof 1 has a holding member corresponding portion 7 arranged above the holding member 4, and a portion 6 other than the holding member corresponding portion 7, in other words, above the raising member 3. It is composed of normal parts (hereinafter referred to as "normal parts") 6 arranged in, and both parts 6 and 7 are separated from each other by the valley parts 6a and 7a as shown in FIG. Will be done.
Regarding the normal portion 6 of the tight frame 5, for example, a commercially available tight frame can be used as it is, and the valley portion 6a of the normal portion 6 is formed on the upper surface of the raising member 3 as shown in FIG. It is placed and welded to the raising member 3 to be supported.
The portion 7 corresponding to the holding member of the tight frame 5 is manufactured by processing a commercially available tight frame, or is specially manufactured by a metal flat plate. As shown in FIG. 3, the valley portions 7a located at both ends of the holding member corresponding portion 7 are placed on the upper surface of the connecting portion 4c of the holding member 4, welded to and supported by the connecting portion 4c, and the central valley portion. 7a is placed on the upper surface of the central flat portion 4b of the holding member 4, and is welded to and supported by the central flat portion 4b.

タイトフレーム５の通常の部位６に関しては、各谷部６ａが全て嵩上げ部材３の上面に載置支持されるので、タイトフレーム５の山部の上面は同じレベルに維持される。
それに対し、タイトフレーム５の保持部材対応部位７に関しては、両端に位置する谷部７ａが保持部材４の接続部位４ｃの上面に載置支持され、中央に位置する谷部７ａが保持部材４の中央平坦部位４ｂの上面に載置支持されるので、予めその分を見越した状態で、保持部材対応部位７の上下方向高さが、通常の部位６の上下方向高さより低く設定され、タイトフレーム５の山部の上面が、保持部材対応部位７から通常の部位６に亘って全て同じレベルになるように構成される。
そのため、保持部材４とタイトフレーム５の保持部材対応部位７に関しては、予め作製しておくのが好ましく、両者を互いに接続した状態で作製しておくのが更に好ましい。 With respect to the normal portion 6 of the tight frame 5, since all the valley portions 6a are placed and supported on the upper surface of the raising member 3, the upper surface of the mountain portion of the tight frame 5 is maintained at the same level.
On the other hand, with respect to the holding member corresponding portion 7 of the tight frame 5, the valley portions 7a located at both ends are placed and supported on the upper surface of the connecting portion 4c of the holding member 4, and the valley portion 7a located at the center is the holding member 4. Since it is placed and supported on the upper surface of the central flat portion 4b, the vertical height of the holding member corresponding portion 7 is set lower than the vertical height of the normal portion 6 in anticipation of that amount in advance, and the tight frame. The upper surface of the mountain portion of 5 is configured to be at the same level from the holding member corresponding portion 7 to the normal portion 6.
Therefore, it is preferable to prepare the holding member 4 and the holding member corresponding portion 7 of the tight frame 5 in advance, and it is more preferable to manufacture them in a state where they are connected to each other.

（第２実施形態）
第２実施形態を説明するにあたっては、重複説明を避けるため、第１実施形態で説明した構成については同じ符号を付し、それによって詳しい説明を省略して、主に第１実施形態と異なる構成について説明する。
第２実施形態による屋根の支持構造が第１実施形態と異なる点は、図４に示すように、第１実施形態における嵩上げ部材３がなく、金属製の平板からなる保持部材４が、鉄骨連結箇所の上方を跨ぐように配置されて、保持部材４の両端に延設の接続部位４ｃが、梁２の上面に直接載置され、梁２に溶接されて支持される点である。 (Second Embodiment)
In explaining the second embodiment, in order to avoid duplicate explanations, the configurations described in the first embodiment are designated by the same reference numerals, and detailed description thereof is omitted thereby, and the configurations are mainly different from those of the first embodiment. Will be explained.
As shown in FIG. 4, the roof support structure according to the second embodiment is different from the first embodiment in that the holding member 4 made of a metal flat plate is connected to the steel frame without the raising member 3 in the first embodiment. A connection portion 4c that is arranged so as to straddle the upper part of the portion and extends to both ends of the holding member 4 is directly placed on the upper surface of the beam 2 and is welded to and supported by the beam 2.

第２実施形態の保持部材４は、嵩上げ部材３がない分だけ下方に位置して鉄骨連結箇所に近づくことになり、したがって、ボルト・ナット９との干渉を避けるため、第１実施形態のものと比べて多少大きくなる。すなわち、上下方向高さが高くなり、かつ、長さ（図４において紙面に沿う横方向長さ）が長くなる。
ところで、図４を参照して、タイトフレーム５の保持部材対応部位７における中央の谷部７ａは、必ずしも鉄骨２ａ、２ｂの突合せ箇所の真上にくるとは限らず、左右にずれる可能性がある。図４では谷部７ａが突合せ箇所より左にずれた状態を示しているが、このような場合、保持部材４が大きい分だけ左右のずれを吸収し易いという利点がある。
その他、第２実施形態では、タイトフレーム５における通常の部位６と保持部材対応部位７が、別体ではなくて一連に連続した状態に構成され、タイトフレーム５の山部の上面が全体として同じレベルになるように、保持部材対応部位７の高さが通常の部位６より低く構成される。 The holding member 4 of the second embodiment is located below by the amount that the raising member 3 is not present and approaches the steel frame connecting portion. Therefore, in order to avoid interference with the bolts and nuts 9, the holding member 4 of the first embodiment is used. It will be slightly larger than that. That is, the height in the vertical direction becomes high, and the length (the horizontal length along the paper surface in FIG. 4) becomes long.
By the way, referring to FIG. 4, the central valley portion 7a in the holding member corresponding portion 7 of the tight frame 5 does not always come directly above the abutting portion of the steel frames 2a and 2b, and may be displaced to the left or right. be. FIG. 4 shows a state in which the valley portion 7a is displaced to the left from the butted portion. In such a case, there is an advantage that the holding member 4 is larger and can easily absorb the left-right deviation.
In addition, in the second embodiment, the normal portion 6 and the holding member corresponding portion 7 in the tight frame 5 are not separate but are configured in a series of continuous states, and the upper surface of the mountain portion of the tight frame 5 is the same as a whole. The height of the holding member corresponding portion 7 is configured to be lower than that of the normal portion 6 so as to reach the level.
