Description
本発明は屋根受け用材、その製造方法、剛接合部被覆方法、および剛接合部被覆構造に係り、特に、現場での鉄骨組立て後に現場溶接を不要とすることのできる、屋根受け用材等に関するものである。 The present invention relates to a roof receiving material, a method for manufacturing the same, a method for covering a rigid joint, and a structure for covering a rigid joint, and more particularly to a roof receiving material that can eliminate on-site welding after assembling a steel frame on site. Is.
図７は、建築における一般鉄骨構造を示す側面図である。また、図８は、図７の要部を示す側面図である。現場での鉄骨組立て後に、図示するような折板屋根７８０やＱＬルーフ（登録商標）、Ｉルーフ等の屋根を施工する場合、梁７７０とする鉄骨本体には、あらかじめ工場において屋根受け枕材（以下、単に「受け材」とも言う。）７３０が取付けられている。折板屋根７８０等の屋根を施工するためにはこの受け材７３０が必要であり、受け材７３０の上に屋根が取付けられる。 FIG. 7 is a side view showing a general steel structure in architecture. Further, FIG. 8 is a side view showing a main part of FIG. 7. When constructing a roof such as a folded plate roof 780, QL roof (registered trademark), or I roof as shown in the figure after assembling the steel frame at the site, the steel frame body to be the beam 770 is preliminarily covered with a roof support pillow material at the factory. Hereinafter, it is also simply referred to as a “receiving material”) 730 is attached. This receiving material 730 is required for constructing a roof such as a folded plate roof 780, and the roof is mounted on the receiving material 730.
図中の鉄骨ボルト継手（「鉄骨現場継手」とも言う。）７４０は、剛接合部ないしは剛構造とよばれる構造において一般的に使用されている継手である。
鉄骨ボルト継手７４０ではボルトの頭が鉄骨（梁７７０）上面に突出することになり、鉄骨（梁７７０）全体としての平面がとれないため、かかる鉄骨（梁７７０）に直接屋根を取付けることはできない。そこで受け材７３０が必要となる。
The steel bolt joint (also referred to as “steel field joint”) 740 in the figure is a joint generally used in a structure called a rigid joint or a rigid structure.
In the steel frame bolt joint 740, the head of the bolt protrudes to the upper surface of the steel frame (beam 770), and the flat surface of the steel frame (beam 770) as a whole cannot be taken, so that the roof cannot be directly attached to the steel frame (beam 770). .. Therefore, a receiving material 730 is required.
しかし、継手７４０におけるボルトの締付け作業は現場で行われるため、工場における鉄骨への受け材７３０の取付けでは、鉄骨ボルト継手部分にあたる箇所、すなわち鉄骨の両端部には受け材７３０を設けることはできず、その部分の受け材は切断されて空隙部が形成された状態である。つまり、鉄骨本体の剛接合部には受け材７３０が無いため、在来工法では、鉄骨ボルト継手７４０におけるボルト締付け後、平鋼７２０などを現場溶接し、かかる剛接合部上の空隙部を埋める処理がなされている。 However, since the bolt tightening work in the joint 740 is performed on-site, when the receiving material 730 is attached to the steel frame in the factory, the receiving material 730 can be provided at the portion corresponding to the steel frame bolt joint portion, that is, at both ends of the steel frame. However, the receiving material in that portion is cut to form a gap portion. That is, since there is no receiving material 730 at the rigid joint of the steel frame body, in the conventional construction method, after tightening the bolts at the steel bolt joint 740, flat steel 720 or the like is welded on-site to fill the gap on the rigid joint. It has been processed.
さて、鉄骨構造物に関しては従来、技術的な提案も多くなされている。たとえば後掲特許文献１には、円形支柱の周面に梁を接合させる場合に、周面に適合させるための部材加工が不要で、構造が簡素な鉄骨構造物の屋根受け部における柱梁接合構造として、立設された円形支柱の上端近傍の周面には対面する一対の縦鋼板が長手方向に沿って各々接合され、これら縦鋼板の各上縁部はフランジ蓋鋼板の張出部に接合されるとともに縦鋼板間には少なくともリブ鋼板が連結接合されてソケットボックスを形成し、屋根支持梁の開口端部がソケットボックスの縦鋼板間に挿嵌され、開口端部近傍の側壁に形成された各取付孔と各縦鋼板に設けられた各止着孔とが合致して各孔に止着部材が止着されることで、屋根支持梁が嵌り合い円形支柱間に掛架可能にする、という構成が開示されている。 By the way, many technical proposals have been made in the past regarding steel structures. For example, in Patent Document 1 described later, when a beam is joined to the peripheral surface of a circular column, it is not necessary to process a member to fit the peripheral surface, and the beam-column joining in a roof receiving portion of a steel structure having a simple structure. As a structure, a pair of vertical steel plates facing each other are joined to the peripheral surface near the upper end of the erected circular beam along the longitudinal direction, and each upper edge of these vertical steel plates is formed on an overhanging portion of the flange lid steel plate. At the same time as being joined, at least rib steel plates are connected and joined between the vertical steel plates to form a socket box, and the open end of the roof support beam is inserted between the vertical steel plates of the socket box and formed on the side wall near the open end. The roof support beams fit together and can be hung between the circular columns by matching the mounting holes provided with the mounting holes with the fastening holes provided on the vertical steel plates and fastening the fastening members to the holes. The configuration of doing is disclosed.
図７、８に示したように従来の工法では、鉄骨−鉄骨間の接続部分（剛接合部）には、受け材（屋根受け枕材）７３０が無い部分、つまり空隙部が形成されてしまう。そこで、上述の通り平鋼７２０などを用いて空隙部を埋め、これにより鉄骨の上面全体を平らにして、屋根を取付けられるようにしている。しかし、このような現場での溶接作業では火災事故が発生するという問題があり、対策が必要である。 As shown in FIGS. 7 and 8, in the conventional construction method, a portion without a receiving material (roof receiving pillow material) 730, that is, a gap portion is formed in the connecting portion (rigid joint portion) between the steel frames. .. Therefore, as described above, the gap is filled with flat steel 720 or the like, thereby flattening the entire upper surface of the steel frame so that the roof can be attached. However, there is a problem that a fire accident occurs in such on-site welding work, and countermeasures are required.
そこで本発明が解決しようとする課題は、かかる従来技術の問題点をなくし、建築現場での鉄骨組立て後に上述のような剛接合部における処理が必要な場合であっても、現場での溶接作業を不要とすることのできる技術を提供することである。 Therefore, the problem to be solved by the present invention is to eliminate the problems of the prior art, and even when the above-mentioned treatment at the rigid joint is required after assembling the steel frame at the construction site, the welding work at the site is performed. Is to provide a technology that can eliminate the need for.
本願発明者は上記課題について検討した結果、Ｌ型アングルと止めネジを用いた受け材代替物を試作した。これは、止めネジの機能によって二点支持梁構造を形成し本試作物を鉄骨鉄板に固定できるとともに、上面は受け材と面一の平面をなすことができるものだった。本受け材代替物によれば、現場溶接を要することなく、剛接合部に対してこれを被覆しての屋根受け機能を設けられることを見出し、これに基づいて本発明を完成するに至った。すなわち、上記課題を解決するための手段として本願で特許請求される発明、もしくは少なくとも開示される発明は、以下の通りである。 As a result of studying the above-mentioned problems, the inventor of the present application has made a prototype of a receiving material substitute using an L-shaped angle and a set screw. This was because a two-point support beam structure could be formed by the function of the set screw, and this prototype could be fixed to the steel-framed iron plate, and the upper surface could be flush with the receiving material. According to the present receiving material substitute, it has been found that a roof receiving function can be provided by covering a rigid joint portion without requiring on-site welding, and the present invention has been completed based on this. ..

本発明の屋根受け用材、その製造方法、剛接合部被覆方法、および剛接合部被覆構造は上述のように構成されるため、これらによれば、建築現場での鉄骨組立て後に、剛接合部に対して屋根受け機能を付与する処理が必要な場合であっても、従来のような現場での平鋼等の溶接作業を要することなく、かかる処理を行うことができる。つまり、本発明によって剛接合部の現場溶接を無くせることにより、溶接を原因とする火災事故の発生を防止することができる。本発明は殊に、建築現場の鉄骨構造において屋根受け枕材を取付けることのできない鉄骨ボルト継手箇所に対して、好適に適用することができる。 Since the roof receiving material of the present invention, its manufacturing method, the rigid joint coating method, and the rigid joint coating structure are configured as described above, according to these, after assembling the steel frame at the construction site, the rigid joint is formed. On the other hand, even when a process for imparting a roof receiving function is required, such a process can be performed without requiring the conventional on-site welding work of flat steel or the like. That is, by eliminating on-site welding of rigid joints according to the present invention, it is possible to prevent the occurrence of fire accidents caused by welding. The present invention can be suitably applied particularly to a steel bolt joint portion where a roof support pillow material cannot be attached in a steel structure at a construction site.
従来は、工場の段階で継手部分を除いた箇所に受け材が取付けられた状態の鉄骨を、現場において組立て、継手のボルトを締付けて接合した後、屋根受け機能のための平鋼等が現場溶接される、という手順であった。一方、本願発明の屋根受け用材等によれば、現場での継手のボルト締め付け接合後は、本屋根受け用材を剛接合部の上に載置して、後は止めネジを締付けるだけでよい。したがって、火災発生防止になるのみならず、作業労力・時間も相当に軽減することができ、工程の円滑・迅速な進行にも資することができる。 Conventionally, steel frames with receiving materials attached at the factory stage are assembled at the site, and after the joint bolts are tightened and joined, flat steel for the roof receiving function is installed at the site. The procedure was to be welded. On the other hand, according to the roof receiving material or the like of the present invention, after bolting and joining the joint at the site, it is sufficient to place the main roof receiving material on the rigid joint and then tighten the set screw. Therefore, not only can fires be prevented, but also work labor and time can be significantly reduced, which can contribute to the smooth and rapid progress of the process.
以下、図面により本発明を詳細に説明する。
図１は、本発明の屋根受け用材の構成例を示す斜視図である。また、図２は図１に示した本発明構成例の点対称逆方向からの斜視図、図３は図１等に示した本発明構成例に係る止めネジ部の構成例を示した説明図である。なお、図３中、（ａ）は止めネジ収容体５内に押し込まれる止めネジ６の平面図、（ｂ）は止めネジ６の側面図、（ｃ）は止めネジ収容体５の断面図、（ｄ）は止めネジ収容体５の平面図を示している。
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a configuration example of the roof receiving material of the present invention. Further, FIG. 2 is a perspective view of the configuration example of the present invention shown in FIG. 1 from the opposite direction of point symmetry, and FIG. 3 is an explanatory view showing a configuration example of a set screw portion according to the configuration example of the present invention shown in FIG. Is. In FIG. 3, (a) is a plan view of the set screw 6 pushed into the set screw accommodating body 5, (b) is a side view of the set screw 6, and (c) is a cross-sectional view of the set screw accommodating body 5. (D) shows a plan view of the set screw accommodating body 5.
これらに図示するように本屋根受け用材１０は、鉄骨構造において屋根受け枕材を取付けることのできない箇所である剛接合部に設置するための屋根受け用材であって、Ｌ型アングル状をなしていて屋根受け用の受け部３および後記止めネジ部２の固定用の支持部４からなる本体部材１が２本と、両本体部材１、１の間に設けられる一または複数の止めネジ部２とからなり、止めネジ部２を挟んで両本体部材１、１の支持部４、４同士が対向して略Ｔ字形の断面形状を形成しており、止めネジ部２は止めネジ収容体５とその内部に仕込まれた止めネジ６とからなることを、主たる構成とする。なお、止めネジ部２は本体１の上下端、すなわち受け部３の上面、および支持部４の端面のいずれもから突出しない構成とする。 As shown in these figures, the main roof receiving material 10 is a roof receiving material for being installed at a rigid joint portion where a roof receiving pillow material cannot be attached in a steel frame structure, and has an L-shaped angle shape. There are two main body members 1 composed of a receiving portion 3 for receiving the roof and a supporting portion 4 for fixing the set screw portion 2 described later, and one or more set screw portions 2 provided between the two main body members 1 and 1. The support portions 4 and 4 of both main body members 1 and 1 face each other to form a substantially T-shaped cross-sectional shape with the set screw portion 2 interposed therebetween, and the set screw portion 2 is the set screw accommodating body 5. The main configuration is composed of a set screw 6 and a set screw 6 installed inside the set screw 6. The set screw portion 2 is configured so as not to protrude from the upper and lower ends of the main body 1, that is, the upper surface of the receiving portion 3 and the end surface of the support portion 4.
図示する構成例では設けられている止めネジ部は２個であるが、本発明はこれに限定されず、１個のみでも、また３個以上であってもよい。もっとも、取付けの確実性・取付け後の安定性の点からは２個以上とすることが望ましく、またコストや作業労力の点からは数は少ない方が望ましい。止めネジ部２を２個とすることで十分な取付け効果が得られ、かつコストや作業労力の点でも不利益はない。したがってこれらの観点から、止めネジ部２を２個とすることは推奨される。 In the illustrated configuration example, the number of set screw portions provided is two, but the present invention is not limited to this, and the present invention may be only one or three or more. However, from the viewpoint of mounting reliability and stability after mounting, it is desirable to have two or more, and from the viewpoint of cost and work labor, it is desirable that the number is small. By using two set screw portions 2, a sufficient mounting effect can be obtained, and there is no disadvantage in terms of cost and work labor. Therefore, from these viewpoints, it is recommended to use two set screw portions 2.
各図に示した構成例では設けられている止めネジ６の種類は、六角穴付き止めネジ（ホーローセット）である。しかし、これ以外の種類の止めネジであってもよい。たとえば、すりわり付き止めネジ、四角止めネジなど、要するに通常のネジのような頭部がなくねじ込み対象内部へと無制限にねじ込む（押し込む）ことができて、後述するように固定対象である剛接合部（鉄骨鉄板）に当接し、二点支持梁構造を構成し得る止めネジであればよい。また、止めネジの先端部形状も特に限定されず、平先，とがり先，棒先，くぼみ先，丸先など、止めネジによる剛接合部への固定作用に支障のない限り、如何なるものでもよい。 The type of set screw 6 provided in the configuration example shown in each figure is a hexagon socket set screw (enamel set). However, other types of set screws may be used. For example, there is no head like a normal screw such as a set screw with a slip, a square set screw, etc., and it can be screwed (pushed) into the inside of the screwing target without limit, and it is a rigid joint that is a fixing target as described later. Any set screw may be used as long as it abuts on the portion (steel steel plate) and can form a two-point support beam structure. Further, the shape of the tip of the set screw is not particularly limited, and any shape such as a flat tip, a pointed tip, a rod tip, a dented tip, and a round tip may be used as long as the fixing action of the set screw to the rigid joint is not hindered. ..
図４、４−２は、図１等に示した本発明屋根受け用材構成例の作用を示す断面図であり、それぞれ、固定前状況、固定状況を示す。これらに示すように本発明屋根受け用材１０は、止めネジ部２を構成する止めネジ６をねじ込む（押し込む）ことによって、剛接合部である鉄骨鉄板５０への取付けがなされる。すなわち、止めネジ部２において止めネジ収容体６の中に収容されている止めネジ６を、上方からインパクトドライバやレンチ等を用いてねじ込む（押し込む）と、止めネジ６は本屋根受け用材１０の支持部４の端面を超えて下方へと突出していき、鉄骨鉄板５０上面に当接、押圧する。一方、止めネジ６以外の屋根受け用材１０全体は、相対的に上方へと持ち上がっていく状態が形成される。これらの作用によって本屋根受け用材１０は剛接合部に固定されるのだが、さらに図５により説明を加える。 4 and 4-2 are cross-sectional views showing the operation of the roof receiving material configuration example of the present invention shown in FIG. 1 and the like, and show the pre-fixing state and the fixing state, respectively. As shown in these, the roof receiving material 10 of the present invention is attached to the steel frame iron plate 50 which is a rigid joint portion by screwing (pushing) the set screw 6 constituting the set screw portion 2. That is, when the set screw 6 housed in the set screw accommodating body 6 in the set screw portion 2 is screwed (pushed in) from above using an impact driver, a wrench, or the like, the set screw 6 is the main roof receiving material 10. It protrudes downward beyond the end face of the support portion 4 and abuts and presses against the upper surface of the steel frame iron plate 50. On the other hand, the entire roof receiving material 10 other than the set screw 6 is formed in a state of being relatively lifted upward. The roof receiving material 10 is fixed to the rigid joint by these actions, which will be further described with reference to FIG.
図５は、本発明屋根受け用材の使用方法および作用を示す断面図である。図示するように本屋根受け用材１０は、剛接合部である鉄骨継手４０の上方に――この箇所は、現場ボルト締め付け作業の便のために、梁（鉄骨）７０に既設の屋根受け枕材（受け材）３０がカットされている箇所である――各端部が両側の受け材３０、３０が設けられた梁８鉄骨）７０、７０の下になるように載置され、インパクトドライバＤ等のねじ込み（押し込み）手段を用いて止めネジ部２の止めネジ６がねじ込み（押し込み）作用を受け、それによって止めネジ６は本屋根受け用材１０の支持部４下端面を突出して鉄骨鉄板５０上面に当接し、押圧されていき、止めネジ６と鉄骨鉄板５０との間で摩擦抵抗が生じる。 FIG. 5 is a cross-sectional view showing a method and operation of the roof receiving material of the present invention. As shown in the figure, the main roof receiving material 10 is above the steel joint 40, which is a rigid joint-this part is the existing roof receiving pillow material on the beam (steel frame) 70 for the convenience of on-site bolt tightening work. (Receiving material) 30 is the cut part-each end is placed so as to be under the beam 8 steel frame provided with the receiving materials 30 and 30 on both sides) 70, 70, and the impact driver D The set screw 6 of the set screw portion 2 is screwed (pushed) by using a screwing (pushing) means such as, and the set screw 6 projects the lower end surface of the support portion 4 of the main roof receiving material 10 and the steel frame steel plate 50. It comes into contact with the upper surface and is pressed, and frictional resistance is generated between the set screw 6 and the steel frame steel plate 50.
一方、その反動で止めネジ６を除く本屋根受け用材１０全体は上昇していく。そうすると、屋根受け用材１０の各端部は受け材３０の内側天井面に当接し、押圧していき、受け部３と受け材３０の内側天井面との間で摩擦抵抗が生じる。このようにして本屋根受け用材１０における止めネジ６のねじ込み（押し込み）は、止めネジ６と鉄骨鉄板５０との間の摩擦抵抗、および受け部３と受け材３０の内側天井面との間の摩擦抵抗、２箇所の摩擦抵抗を生じ、二点支持梁構造が形成される。これにより、本屋根受け用材１０は剛接合部に対して確実に固定される。 On the other hand, due to the reaction, the entire roof receiving material 10 excluding the set screw 6 rises. Then, each end portion of the roof receiving member 10 abuts on the inner ceiling surface of the receiving member 30 and presses the roof receiving member 10, and frictional resistance is generated between the receiving portion 3 and the inner ceiling surface of the receiving member 30. In this way, the screwing (pushing) of the set screw 6 in the roof receiving material 10 is performed by the frictional resistance between the set screw 6 and the steel frame steel plate 50 and between the receiving portion 3 and the inner ceiling surface of the receiving material 30. Friction resistance is generated at two points, and a two-point support beam structure is formed. As a result, the roof receiving material 10 is securely fixed to the rigid joint.
図５では止めネジ部２が２箇所設けられている屋根受け用材１０の構成例であり、これに即して説明を重ねる。止めネジ収容体５の中に収容されている止めネジ６をインパクトドライバＤ等で回転させ下方に押し込むことによって、下方にある鉄骨鉄板５０に当接した止めネジ６先端には鉄骨鉄板５０に生じる反発力によって、２箇所の作用箇所Ｂ、Ｂにおいて摩擦抵抗が発生する。 FIG. 5 is a configuration example of the roof receiving material 10 in which the set screw portions 2 are provided at two locations, and the description will be repeated according to this. By rotating the set screw 6 housed in the set screw accommodating body 5 with an impact driver D or the like and pushing it downward, the tip of the set screw 6 in contact with the steel frame iron plate 50 below is generated on the steel frame iron plate 50. Due to the repulsive force, frictional resistance is generated at the two action points B and B.
一方、止めネジ６に対して回転（ねじ込み）による押し込みがなされることで、止めネジ６が鉄骨鉄板５０上面に当接した後は止めネジ６を除く屋根受け用材１０全体が押し上げられる作用が働く。これによって屋根受け用材１０（止めネジ６を除く）は上昇し、その両端がそれぞれ、受け材３０、３０の内側天井面で押さえつけられるため、２箇所の作用箇所Ａ、Ａにおいて反発力による摩擦抵抗が発生する。 On the other hand, since the set screw 6 is pushed by rotation (screw), after the set screw 6 comes into contact with the upper surface of the steel frame iron plate 50, the entire roof receiving material 10 excluding the set screw 6 is pushed up. .. As a result, the roof receiving material 10 (excluding the set screw 6) rises, and both ends thereof are pressed by the inner ceiling surfaces of the receiving materials 30 and 30, respectively. Therefore, frictional resistance due to repulsive force at the two action points A and A. Occurs.
このようにして二点支持梁構造が構成され、結局本例屋根受け用材１０では、Ａ２点、Ｂ２点、計４点の摩擦抵抗が発生することによって、剛接合部への固定がなされる。以上の説明した作用により、本発明屋根受け用材１０は、鉄骨構造において屋根受け枕材を取付けることのできない箇所である剛接合部に、現場溶接を要せず、ただ止めネジ６のねじ込み（押し込み）を行うことによってのみ設置される。 In this way, the two-point support beam structure is configured, and in the end, the roof receiving material 10 of this example is fixed to the rigid joint portion by generating frictional resistances at two points, A2 and B2, for a total of four points. Due to the action described above, the roof receiving material 10 of the present invention does not require on-site welding at the rigid joint where the roof receiving pillow material cannot be attached in the steel structure, and the set screw 6 is simply screwed (pushed in). ) Is installed only by doing.
なお、本屋根受け用材１０の本体１の形状・寸法等の仕様は、これを構成する受け部３が平面状であり、支持部４、４が止めネジ部２を両側から支持して固定できるものである限り、特に限定されず、自由に設計し得る。 Regarding the specifications such as the shape and dimensions of the main body 1 of the roof receiving material 10, the receiving portion 3 constituting the main body 1 is flat, and the supporting portions 4 and 4 can support and fix the set screw portion 2 from both sides. As long as it is a thing, it is not particularly limited and can be freely designed.
本発明屋根受け用材１０の本体部材１は、Ｌ型アングルにより形成するものとすることができる。すなわちＬ型アングルを、本屋根受け用材１０の取付が必要な空隙部よりも長い寸法に切断すれば、本体部材１を作製することができる。もちろん、鉄板など板材を折り曲げて作製してもよい。いずれの方法で本体部材１を作製するとしても、これにより最終的に形成される屋根受け用材１０は、止めネジ部２を挟んで前記両本体部材１、１の支持部４、４同士が対向して略Ｔ字形の断面形状をなす形態となる。 The main body member 1 of the roof receiving material 10 of the present invention can be formed by an L-shaped angle. That is, the main body member 1 can be manufactured by cutting the L-shaped angle to a size longer than the gap portion where the roof receiving material 10 needs to be attached. Of course, it may be produced by bending a plate material such as an iron plate. Regardless of which method is used to produce the main body member 1, the roof receiving material 10 finally formed by this method has the support portions 4, 4 of the two main body members 1, 1 facing each other with the set screw portion 2 interposed therebetween. Therefore, it has a substantially T-shaped cross-sectional shape.
本屋根受け用材１０において、その止めネジ収容体５は、止めネジ６を収容し、かつそれがねじ込まれる（押し込まれる）時に止めネジ５の外表面との間で反発力による摩擦を生じ、それにより、止めネジ収容体５―止めネジ６間の相対位置が直線的に変化し、図４−２や図５を用いて説明した作用を可能ならしめ、ねじ込み（押し込み）が終了した静止状態においては両者間の位置関係が確実に固定されるものであり、そして本体部材１との間で一体化できるものである限り、如何なる具体的な構造であってもよい。たとえば、市販のナットや別途製作するナットを止めネジ収容体５として好適に用いることができるが、本発明はそれに限定されない。 In the roof receiving material 10, the set screw accommodating body 5 accommodates the set screw 6, and when it is screwed (pushed in), friction due to a repulsive force is generated between the set screw accommodating body 5 and the outer surface of the set screw 5. As a result, the relative position between the set screw housing 5 and the set screw 6 changes linearly, enabling the operation described with reference to FIGS. 4-2 and 5, and in a stationary state in which the screwing (pushing) is completed. Can have any specific structure as long as the positional relationship between the two is surely fixed and can be integrated with the main body member 1. For example, a commercially available nut or a nut manufactured separately can be suitably used as the set screw accommodating body 5, but the present invention is not limited thereto.
また、鉄骨構造において屋根受け枕材を取付けることのできない箇所（特定箇所）に設置するための屋根受け用材を製造する方法も本発明の範囲内であるが、これについて説明する。
屋根受け枕材を製造する材料としては、以下のものを用意する。
１）Ｌ型アングル状をなしていて屋根受け用の受け部ならびに止めネジ部固定用の支持部からなる本体部材 二本
なお本体部材としては、Ｌ型アングルを切断したものの利用が便利である。
２）止めネジ収容体とその内部に収容された止めネジとから構成される止めネジ部 所望の個数
Further, a method of manufacturing a roof support material for installing a roof support pillow material in a place (specific place) where the roof support pillow material cannot be attached in a steel frame structure is also within the scope of the present invention, but this will be described.
The following materials are prepared for manufacturing the roof support pillow material.
1) Two main body members that are L-shaped and consist of a receiving part for receiving the roof and a support part for fixing the set screw. It is convenient to use a cut L-shaped angle as the main body member.
2) A desired number of set screw portions composed of a set screw housing and a set screw housed inside the set screw housing.
これらの材料により、本体の略Ｔ字形の断面形状を形成するよう、
一方の該本体部材の支持部―該止めネジ部―他方の該本体部材の支持部
の間を接合し、一体とする。本発明は建築における鉄骨構造の分野に属するものであり、したがって具体的な接合手段としては溶接を用い、これにより各材料を一体に接合することが推奨される。以上の手順により、屋根受け用材を製造することができる。
With these materials, a substantially T-shaped cross-sectional shape of the main body is formed.
The support portion of one main body member, the set screw portion, and the support portion of the other main body member are joined and integrated. The present invention belongs to the field of steel structures in architecture, and therefore it is recommended to use welding as a specific joining means, thereby joining each material integrally. By the above procedure, the roof receiving material can be manufactured.
また、以上説明したいずれかの屋根受け用材を、鉄骨構造において屋根受け枕材を取付けることのできない箇所である剛接合部に取付けることにより行う剛接合部被覆方法も本発明の範囲内である。前出図１、４−２、５等を参照しつつ説明すれば、本発明剛接合部被覆方法は、長手方向寸法が被覆すべき長さよりも長い屋根受け用材１０を、両側の屋根受け枕材（受け材）３０の下方に各端部が位置するように剛接合部上に置き、剛接合部に向かって屋根受け用材１０の止めネジ部２中の止めネジ６を押し込む、という手順で行うことができる。 Further, a rigid joint covering method performed by attaching any of the roof receiving materials described above to a rigid joint where the roof supporting pillow material cannot be attached in the steel frame structure is also within the scope of the present invention. Explaining with reference to FIGS. 1, 4-2, 5 and the like above, the rigid joint covering method of the present invention uses a roof receiving material 10 whose longitudinal dimension is longer than the length to be covered, and roof receiving pillows on both sides. Place it on the rigid joint so that each end is located below the material (receiving material) 30, and push the set screw 6 in the set screw portion 2 of the roof receiving material 10 toward the rigid joint. It can be carried out.
なおまた、鉄骨構造において屋根受け枕材を取付けることのできない箇所である剛接合部が被覆されている構造であって、以上説明したいずれかの屋根受け用材が当該剛接合部に取付けられてなる剛接合部被覆構造も、本発明の範囲内である。 Further, the structure is such that the rigid joint portion where the roof receiving pillow material cannot be attached is covered in the steel frame structure, and any of the roof receiving materials described above is attached to the rigid joint portion. The rigid joint covering structure is also within the scope of the present invention.
図６は、本発明屋根受け用材の実施例を示す説明図である。図中に示す寸法、止めネジ部２２の数ならびに止めネジ２６の種類などの具体的仕様は一例であり、本発明はこれらに限定されない。なお、図中（ｅ）は実施例屋根受け用材２１０の底面図（支持部２４方向から見た図）、（ｆ）は止めネジ部箇所における側断面図である。 FIG. 6 is an explanatory view showing an embodiment of the roof receiving material of the present invention. Specific specifications such as the dimensions shown in the figure, the number of set screw portions 22, and the type of set screw 26 are examples, and the present invention is not limited thereto. In the figure, (e) is a bottom view (viewed from the support portion 24 direction) of the roof receiving material 210 of the embodiment, and (f) is a side sectional view of the set screw portion.
本体部材２１は、Ｌ型アングルを所定の長さに切断して２本作製した。止めネジ部２２には、止めネジ２６としてＭ８ホーローセット、止めネジ収容体２５としてＭ８×３０ナットを用い、止めネジ２６を止めネジ収容体２５に内蔵して止めネジ部２２とした。本体部材２１―止めネジ部２２―本体部材２１を溶接し、屋根受け用材２１０の構成を完成したが、その後、最後に現場の仕様に合わせた塗装を施した。 Two main body members 21 were manufactured by cutting an L-shaped angle to a predetermined length. An M8 enamel set was used as the set screw 26 and an M8 × 30 nut was used as the set screw accommodating body 25 for the set screw portion 22, and the set screw 26 was incorporated in the set screw accommodating body 25 to form the set screw portion 22. The main body member 21-set screw portion 22-main body member 21 were welded to complete the structure of the roof receiving material 210, but after that, the coating was finally applied according to the specifications of the site.
本屋根受け用材２１０を、鉄骨ボルト継手部分の鉄骨鉄板に対して固定できるか否か試験した。止めネジ２６（ホーローセット）をインパクトドライバ等を用いて押し込んだところ、ごく短時間で、簡単に本屋根受け用材２１０を剛接合部に確実に固定することができた。二点支持梁構造の原理による本発明屋根受け用材の有用性を確認することができた。 It was tested whether or not the roof receiving material 210 could be fixed to the steel frame steel plate of the steel frame bolt joint portion. When the set screw 26 (enamel set) was pushed in using an impact driver or the like, the roof receiving material 210 could be easily and securely fixed to the rigid joint in a very short time. We were able to confirm the usefulness of the roof receiving material of the present invention based on the principle of the two-point support beam structure.
本発明の屋根受け用材、その製造方法、剛接合部被覆方法、および剛接合部被覆構造によれば、建築現場での鉄骨組立て後、剛接合部に対する屋根受け機能付与処理が必要な場合でも、現場溶接を要することなく行うことができる。これにより、火災事故の発生を防止できるのみならず、作業労力・時間も相当に軽減でき、工程の円滑・迅速な進行にも資する。したがって、建築分野および関連する全分野において、産業上利用性が高い発明である。 According to the roof receiving material of the present invention, its manufacturing method, the rigid joint coating method, and the rigid joint coating structure, even when it is necessary to impart the roof receiving function to the rigid joint after assembling the steel frame at the construction site. It can be done without the need for on-site welding. As a result, not only the occurrence of a fire accident can be prevented, but also the work labor and time can be considerably reduced, which contributes to the smooth and rapid progress of the process. Therefore, it is an invention with high industrial applicability in the field of construction and all related fields.
