Description

本発明は、工場建築物やプラント構造物において、各階の天井付近に、比較的大口径の配管を吊持して支持することができる配管耐震用サポートに関するものであって、特に、配管耐震用サポートを構成する溝型鋼より成る吊材と横架材とを、ガセットプレートを用いることなく、また溶接することもなく、ボルトとナットを介して接合固定して、強度性を保持することにより、耐震性を付与すると共に、簡単、且つ容易に製作できる配管耐震用サポートに関するものである。 The present invention relates to a seismic support for piping capable of suspending and supporting a relatively large-diameter pipe in the vicinity of the ceiling of each floor in a factory building or plant structure. By maintaining the strength by joining and fixing the hanger and horizontal member made of channel steel constituting the support, without using a gusset plate or welding, via bolts and nuts, The present invention relates to a seismic support for piping that can be easily and easily manufactured while providing seismic resistance.

従来、工場建築物やプラント構造物において、各階の天井付近に、比較的大口径の配管を吊持して支持する配管耐震用サポートは、図５に示すように溝型鋼を凹字状に固定したガセットプレート接合タイプや、図６に示すようにＨ型鋼を凹字状に溶接固定した溶接接合タイプが汎用されている。 Conventionally, pipes with a relatively large diameter are supported near the ceiling of each floor in factory buildings and plant structures, and the seismic support for piping is fixed in a concave shape as shown in Fig. 5. The gusset plate joining type and the welding joining type in which H-shaped steel is welded and fixed in a concave shape as shown in FIG. 6 are widely used.

一方、配管耐震用サポートとして、ガセットプレート接合や、溶接接合を全く使用しないタイプにつき、過去の特許文献を遡及検索しても、１件の特許文献をも発見することができなかった。 On the other hand, as a seismic support for piping, it was not possible to find one patent document even if a past patent document was searched retrospectively for a type that does not use gusset plate bonding or welded bonding at all.

前記従来汎用されている図５のガセットプレート接合タイプのサポート３１は、溝型鋼により形成された２本の吊材３２の下端部にガセットプレート３３を取付けて、該各ガセットプレート３３に横架材３４の両端をボルト３５で接合するという構造であるため、配管３６を固定するＵバンド３７とガセットプレート３３が干渉しないように、配管３６と吊材３２との間隔を必要以上に確保しなければならないので、横架材３４の長さが長くなり、従って、その分コスト高となり、また、ガセットプレート３３は、サポート製作時や現場施工時に邪魔となり、該ガセットプレート３３の露出部分が作業員と接触する等、安全性に課題があった。更に、吊材３２と横架材３４とを直接固定するのではなく、ガセットプレート３３を介して固定しているので、耐震性の面で劣るという課題があった。 The conventional gusset plate joint type support 31 shown in FIG. 5 has a gusset plate 33 attached to the lower ends of two suspension members 32 formed of channel steel, and a horizontal member is attached to each gusset plate 33. Since both ends of 34 are joined by bolts 35, an interval between the pipe 36 and the suspension member 32 must be ensured more than necessary so that the U band 37 for fixing the pipe 36 and the gusset plate 33 do not interfere with each other. Therefore, the length of the horizontal member 34 is increased, and accordingly, the cost is increased accordingly. Further, the gusset plate 33 becomes an obstacle at the time of production of the support or construction at the site, and the exposed portion of the gusset plate 33 is in contact with the worker. There was a problem in safety such as contact. Furthermore, since the suspension member 32 and the horizontal member 34 are not directly fixed, but are fixed via the gusset plate 33, there is a problem in that they are inferior in terms of earthquake resistance.

また、前記従来汎用されている図６の溶接接合タイプのサポート４１は、吊材４２と横架材４３とがその接合部において、溶接４４されて一体に構成されているため、重量が嵩んでサポート製作時や現場への搬入および施工に手間がかかり、更に広い保管スペースが必要であり、また溶接４４の品質を確保するために、溶接の熟練工が必要となり、コスト削減の障害となるという課題があった。更に、吊材４２と横架材４３とを溶接４４により固定しているので、該溶接４４が充分でないと、耐震性の面で劣るという課題があった。なお、図中、４５は配管、４６はＵバンドである。 Further, the conventional welded joint type support 41 of FIG. 6 has a heavy weight because the suspension member 42 and the horizontal member 43 are integrally formed by welding 44 at the joint portion. The problem is that it takes time to produce and install the support and to the site, and requires a larger storage space. Also, in order to ensure the quality of the weld 44, a skilled worker in welding is required, which is an obstacle to cost reduction. was there. Furthermore, since the suspension member 42 and the horizontal member 43 are fixed by the welding 44, there is a problem that if the welding 44 is not sufficient, the earthquake resistance is inferior. In the figure, 45 is a pipe and 46 is a U-band.

本発明は、前記課題を解決すべくなされたもので、吊材と横架材に溝型鋼を使用し、各溝型鋼の平板状面同土を当接して面接触させて、直接ボルトとナットで連結固定し、ガセットプレートを不要として、Ｕバンドとの干渉をなくすことにより、横架材として必要最短長さ（配管を支持する長さ）のものを使用することができ、また、前記面接触部において、吊材と横架材とをボルトとナットにより連結固定することにより、耐震性を保持することができ、更に溶接作業も不要で、吊材と横架材の現場での連結固定が可能であるので、吊材と横架材の現場への搬入が容易で、且つ製作も迅速、且つ簡単にでき、コスト削減を図ることができる配管耐震用サポートを提供しようとするものである。 The present invention has been made to solve the above-mentioned problems, and uses a grooved steel for the suspension member and the horizontal member, and contacts the flat plate surface of each grooved steel to bring them into surface contact with each other. By connecting and fixing with, eliminating the need for a gusset plate and eliminating interference with the U-band, it is possible to use the horizontal member with the necessary minimum length (the length to support the piping). At the contact part, the suspension material and the horizontal member are connected and fixed with bolts and nuts, so that the earthquake resistance can be maintained, and further, welding work is not required. Therefore, it is intended to provide a seismic support for piping that can easily carry suspended materials and horizontal members to the site, can be manufactured quickly and easily, and can reduce costs. .

本発明は、間隔を有して配設された２本の溝型鋼より成る吊材１の平板状の背面板２の下端に、溝型鋼より成る横架材３の平板状の背面板４を当接して面接触させ、その接触部を複数本のボルト５とナット６とを介して一体に接合固定する一方、１本、または複数本の配管８の上方より被着するＵバンド９の両端部を挿入固定する貫通孔１０を穿設したＬ字状の取付金具１１を、前記Ｕバンド９の各両端部下面に位置する、前記横架材３の平板状の背面板４の上端部にボルト１２とナット１３とを介して接合固定するという手段を採用することにより、上記課題を解決した。 In the present invention, a flat back plate 4 of a horizontal member 3 made of channel steel is provided at the lower end of a flat back plate 2 of a suspension material 1 made of two channel steels arranged at intervals. The contact portions are brought into surface contact and the contact portions are integrally joined and fixed via a plurality of bolts 5 and nuts 6, while both ends of the U band 9 attached from above one or a plurality of pipes 8. L-shaped mounting brackets 11 having through-holes 10 for inserting and fixing the portions are located at the upper end portions of the flat back plate 4 of the horizontal member 3 located on the lower surfaces of both end portions of the U band 9. The above-mentioned problem has been solved by adopting a means of fixing by means of bolts 12 and nuts 13.

本発明配管耐震用サポートは、溝型鋼より成る吊材１と横架材３の平板状の各背面板２・４を当接して面接触させ、その接触部を複数本のボルト５とナット６とを介して一体に連結固定するという接合方法であるため、前記吊材１と横架材３とが強固に接合固定されるので、耐震性が付与され、更に、従来のように、ガセットプレートが不要となり、またＵバンド９との干渉がないので、横架材３はガセットプレート接合タイプのものより短かい鋼材を使用することができると共に、溶接作業が不要であるため、製作が容易で、且つコストの低減を図ることができるという優れた効果を奏する。 In the seismic support for piping according to the present invention, the suspension member 1 made of channel steel and the flat back plates 2 and 4 of the horizontal member 3 are brought into contact with each other and brought into surface contact with each other. Since the suspension member 1 and the horizontal member 3 are firmly joined and fixed together, it is provided with seismic resistance, and moreover, as in the conventional case, the gusset plate Since there is no interference with the U-band 9, the horizontal member 3 can be made of a steel material shorter than that of the gusset plate joint type and can be manufactured easily because no welding work is required. And the outstanding effect that cost reduction can be aimed at is produced.

更に、本発明配管耐震用サポートは、配管８の自重を支持すると共に、地震時において、前記配管８が水平方向に発生する慣性力（地震力）も、同時に支持することができるのて、前記地震力に抵抗することができ、耐震性を保持することができる。 Furthermore, the seismic support for piping according to the present invention supports the own weight of the piping 8 and can simultaneously support the inertial force (seismic force) generated in the horizontal direction by the piping 8 during an earthquake. It can resist seismic force and maintain seismic resistance.

本発明の実施例を図面に基づいて詳細に説明するに、図１は本発明配管耐震用サポートの正面図である。本発明配管耐震用サポートは、間隔を有して配設された２本の溝型鋼より成る吊材１の平板状の背面板２（図２参照）の下端に、溝型鋼より成る横架材３の平板状の背面板４を当接して面接触させ、且つ該接触部を複数本のボルト５とナット６とを介して一体に接合固定して形成されている。前記のように、吊材１の平板状の背面板２と横架材３の平板状の背面板４を当接して面接触させて、複数本のボルト５とナット６とを介して一体に接合固定することにより、曲げ、せん断、軸力の合力を伝達する剛接合を形成しているため、前記吊材１と横架材３はラーメン構造となり、耐震性が充分保持される。なお、図中、７は、前記ボルト５を嵌挿するボルト孔である。 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of the seismic support for piping according to the present invention. The seismic support for piping according to the present invention is a horizontal member made of grooved steel at the lower end of a flat plate 2 (see FIG. 2) of a suspension member 1 made of two grooved steels arranged at intervals. 3 flat plate 4 is contacted and brought into surface contact, and the contact portion is integrally joined and fixed via a plurality of bolts 5 and nuts 6. As described above, the flat plate 2 of the suspension member 1 and the flat plate 4 of the horizontal member 3 are brought into contact with each other and brought into surface contact with each other through a plurality of bolts 5 and nuts 6. By fixing the joint, a rigid joint that transmits the resultant force of bending, shearing, and axial force is formed. Therefore, the suspension member 1 and the horizontal member 3 have a ramen structure, and the earthquake resistance is sufficiently maintained. In the figure, 7 is a bolt hole into which the bolt 5 is inserted.

更に、前記横架材３には、１本、または複数本の配管８（図３においては、２本の配管８が図示されている）の上方より被着して、該横架材３上に該配管８を挟持して載置するため、Ｕバンド９の両端部を挿入固定する貫通孔１０を穿設したＬ字状の取付金具１１が、前記Ｕバンド９の各両端部下面に位置する、前記横架材３の平板状の背面板４の上端部にボルト１２とナット１３とを介してそれぞれ接合固定されている。 Further, the horizontal member 3 is attached from the upper side of one or a plurality of pipes 8 (two pipes 8 are shown in FIG. 3). In order to sandwich and place the pipe 8, L-shaped mounting brackets 11 having through holes 10 for inserting and fixing the both ends of the U band 9 are positioned on the lower surfaces of the both ends of the U band 9. The upper end of the flat plate 4 of the horizontal member 3 is joined and fixed via bolts 12 and nuts 13 respectively.

これにより、配管８はＵバンド９を上方より被着すると共に、該Ｕバンド９の両端部を貫通孔１０に挿入固定することにより、前記配管８は横架材３に動揺することなく配置される。 As a result, the pipe 8 attaches the U band 9 from above, and the pipe 8 is arranged without being shaken by the horizontal member 3 by inserting and fixing both end portions of the U band 9 into the through holes 10. The

また、前記横架材３はガセットプレートを用いることなく吊材２に接合固定されているため、従来のガセットプレートタイプのものと異なり最低必要長さの横架材３で足りる。 Further, since the horizontal member 3 is bonded and fixed to the suspension member 2 without using a gusset plate, the horizontal member 3 having the minimum required length is sufficient unlike the conventional gusset plate type.

前記構成より成る本発明配管耐震用サポートの各吊材１の上端部は、建物大梁１４に固定されるが、その固定手段は、特に限定する必要はないが、好ましくは、図４に示すような構成とすることが推奨される。すなわち、各吊材１の平板状の背面板２に、建物大梁１４に当接する、該吊材１より巾広の取付片１５をボルト１６とナット１７とで連結固定すると共に、該取付片１５と前記建物大梁１４間に、前記ボルト１６の頭部１６ａの厚さ分の間隔を保持するライナープレート１８を介在せしめて、前記取付片１５をアンカーボルト１９により建物大梁１４に一体に連結固定する。 Although the upper end part of each suspension material 1 of the present invention seismic support having the above-described structure is fixed to the building girder 14, the fixing means is not particularly limited, but preferably as shown in FIG. Recommended configuration. That is, an attachment piece 15 that is in contact with the building beam 14 and is wider than the suspension material 1 is connected and fixed to the flat back plate 2 of each suspension material 1 with the bolt 16 and the nut 17, and the attachment piece 15. A liner plate 18 that maintains a gap corresponding to the thickness of the head portion 16a of the bolt 16 is interposed between the building beam 14 and the building beam 14 so that the mounting piece 15 is integrally connected and fixed to the building beam 14 by an anchor bolt 19. .

前記のように、本発明配管耐震用サポートは、溝型鋼より成る吊材１と横架材３の平板状の背面板４を当接して面接触させ、その接触部を複数本のボルト５とナット６とを介して一体に連結固定するという接合方法であるため、吊材１と横架材３とが強固に接合固定されて、耐震性が保持され、更に、従来のように、ガセットプレートが不要となり、またＵバンド９との干渉がないので、横架材３はガセットプレート接合タイプのものより短かい鋼材を使用することができると共に、溶接作業が不要であるため、製作が容易で、且つコストの低減を図ることができる。 As described above, the piping seismic support according to the present invention makes contact between the suspension member 1 made of channel steel and the flat back plate 4 of the horizontal member 3 to bring them into surface contact, and the contact portion is connected to the plurality of bolts 5. Since it is a joining method in which the nuts 6 are integrally connected and fixed, the suspension member 1 and the horizontal member 3 are firmly joined and fixed to maintain the earthquake resistance. Further, as in the conventional case, the gusset plate Since there is no interference with the U-band 9, the horizontal member 3 can be made of a steel material shorter than that of the gusset plate joint type and can be manufactured easily because no welding work is required. In addition, the cost can be reduced.
