Description

本発明は複数の配管吊下支持具を具備する配管の吊下支持構造に関し、詳しくは天井スラブやトンネル天井等の取付面に、各種配管類を数ｍから数十ｍ以上に及ぶ長尺スパンで吊下支持する複数の配管吊下支持具を具備する配管の吊下支持構造に関する。
The present invention relates to a pipe suspension support structure including a plurality of pipe suspension supports, and in particular, a long span extending from several meters to several tens of meters on various mounting surfaces such as ceiling slabs and tunnel ceilings. It is related with the suspension support structure of piping which comprises a plurality of piping suspension supports which are suspended and supported by.

天井スラブやトンネル天井等の取付面に各種配管類を吊下支持するには、例えば、特許文献１〜３等に示すような、吊りボルトと配管バンドとから成る支持構成を一組とする同構成の吊下支持具、或いは、斜めに垂設した１本又は２本の吊下支持杆を更に付加した支持構成を一組とする同構成の吊下支持具を、数ｍないし数十ｍ間隔で複数個配設することにより行われている。   In order to suspend and support various pipes on a mounting surface such as a ceiling slab or a tunnel ceiling, for example, as shown in Patent Documents 1 to 3 and the like, a support structure including a suspension bolt and a piping band is used as a set. A suspension support having the same configuration, or a suspension support having the same configuration in which one or two suspension support rods provided obliquely are further added, is a few meters to a few tens of meters. This is done by arranging a plurality at intervals.

上記の吊下支持構成は、たとえ数百ｍないし数百ｍ以上に及ぶトンネル内配管等のように超長尺スパンにおける吊下支持であっても、前記したような同構成の配管支持具を多数個用いることにより行われている。   Even if the above suspension support structure is a suspension support in a very long span such as a pipe in a tunnel extending over several hundreds of meters to several hundreds of meters or more, the pipe support having the same structure as described above is used. This is done by using a large number.

同構成の配管支持具を長尺スパンにおいて複数個ないし多数個用いて吊下支持した場合、地震等の揺れが発生すると、配管軸方向の振動負荷と配管軸直交方向の振動負荷とが同時に生じることに加えて、捻れを含む軸線回り方向に傾動・揺動する負荷・モーメント・応力・歪等をも生じることになり、揺れを収束させることができないことが多いだけでなく、複数個ないし多数個の配管支持具に掛かる負荷・モーメント・応力・歪等が同調して増幅されてしまうこともあり、配管支持具に歪みや破損が生じ易く、耐震強度の点で問題が起き易いことが判った。   When multiple or many pipe supports with the same configuration are suspended and supported in a long span, vibrations in the direction of the pipe axis and vibrations in the direction perpendicular to the pipe axis are generated simultaneously when vibration such as an earthquake occurs. In addition, it may cause loads, moments, stresses, strains, etc. that tilt and oscillate in the direction around the axis including torsion. It can be seen that loads, moments, stresses, strains, etc. applied to individual pipe supports may be amplified in synchronism, and the pipe supports are likely to be distorted and damaged, and problems are likely to occur in terms of seismic strength.

請求項１に示す発明によれば、トンネル天井への長尺スパンにおける配管吊下支持であっても地震時の防震性及び耐震性の高い複数の配管吊下支持具を具備する配管の吊下支持構造を提供することができる。
According to the first aspect of the present invention, a pipe suspension comprising a plurality of pipe suspension supports having high earthquake resistance and earthquake resistance even in the case of pipe suspension support in a long span to a tunnel ceiling. A support structure can be provided.

２種類の斜め１点吊下支持構成（左サポート支持構成・右サポート支持構成）を有する配管吊下支持具を、配管軸方向において、間に１点吊下支持構成を有する配管吊下支持具を挟んだ状態で交互に吊下配設した構成とすることによって、１点吊下支持構成を挟んで隣接する２種類の斜め吊下支持構成を有する配管吊下支持具同士が平面視した際に配管軸方向において対称の斜め１点吊下支持構成となるので、配管軸方向の振動負荷と配管軸直交方向の振動負荷とが同時に生じることに加えて、捻れを含む軸線回り方向に傾動・揺動する負荷・モーメント・応力・歪等をも生じた場合であっても、様々な方向における揺れを対称構成の２種類の斜め１点吊下支持構成が互いに打ち消す作用効果を発揮し、揺れを収束させることができる。従って、長尺スパンにおける配管吊下支持であっても、複数個ないし多数個の配管支持具に掛かる負荷・モーメント・応力・歪等が同調して増幅されてしまうことを抑制することができ、配管支持具に歪みや破損が生じ難いという効果を有している。また、地震時に震源地の違いによって地震波の入射方向が変わっても、様々な振動方向にも対処することができるという、本発明に係る特定の２種類の斜め１点吊下支持構成による相乗効果を有している。   A pipe suspension support having a one-point suspension support structure between two types of slanted one-point suspension support structures (left support support structure and right support support structure) in the pipe axis direction. When the pipe suspension supports having two types of oblique suspension support structures adjacent to each other with the one-point suspension support structure are viewed in a plan view, the suspension structure is alternately suspended while sandwiching In addition to a symmetrical slanted one-point suspension structure in the pipe axis direction, in addition to the simultaneous occurrence of a vibration load in the pipe axis direction and a vibration load in the direction orthogonal to the pipe axis, tilting in the direction around the axis including torsion Even when oscillating loads, moments, stresses, strains, etc. occur, the two types of slanted one-point suspension support configurations with symmetrical configurations exert the effect of canceling each other out, and swinging in various directions Can be converged. Therefore, even if it is a pipe suspension support in a long span, it can be suppressed that the load, moment, stress, strain, etc. applied to a plurality or a plurality of pipe supports are synchronized and amplified. It has the effect that distortion and breakage hardly occur in the pipe support. In addition, even if the incident direction of the seismic wave changes due to the difference in the epicenter during an earthquake, it is possible to deal with various vibration directions, and the synergistic effect by the two specific slanted one-point suspension support configurations according to the present invention. have.

特に、左サポート支持構成を有する配管吊下支持具と、右サポート支持構成を有する配管吊下支持具との２種類のサポート支持構成と、通常の１点吊下支持構成の採用によって、様々な振動方向にも対処できる、というコスト面及び配管取付面の事情（配管取付面は、必ずしも支持杆を自由に取付け可能であるとは限らない。）を配慮した有意な効果を発揮する。   In particular, by adopting two types of support support configurations, a pipe suspension support having a left support support configuration and a pipe suspension support having a right support support configuration, and a normal one-point suspension support configuration A significant effect in consideration of the cost and the situation of the pipe mounting surface that can cope with the vibration direction (the pipe mounting surface is not necessarily capable of mounting the support rod freely).

また、吊りボルトと配管支持バンドとによる通常の１点吊下支持構成を有する既存の配管設備に、上記した２種類の斜め１点吊下支持構成を有する配管吊下支持具を付加することによって本発明と同様の斜め１点吊下支持構成を有する配管吊下支持具とすることもできる。この場合、既存の１点吊下支持構成を本発明の１点吊下支持構成と見做すことができる。また、既存の１点吊下支持構成の間に、本発明の全ての構成を付加することもできる。即ち、本発明において、間に配設される１点吊下支持構成を有する配管吊下支持具は、少なくとも１つあればよく、１つあったり、２つ以上あったり、混在していてもよい。   Moreover, by adding the above-described two types of pipe suspension supports having the slant one-point suspension support structure to the existing piping equipment having the normal one-point suspension support structure by the suspension bolt and the pipe support band. It can also be set as the piping suspension support tool which has the diagonal 1 point suspension support structure similar to this invention. In this case, the existing one-point suspension support configuration can be regarded as the one-point suspension support configuration of the present invention. Moreover, all the configurations of the present invention can be added between the existing one-point suspended support configurations. That is, in the present invention, at least one pipe suspension support having a one-point suspension support structure disposed between them is sufficient, even if there is one, two or more, or a mixture. Good.

以上の効果によって、配管支持具や吊りボルト等の配管支持構成のみならず、配管そのもの、配管の接続部分・継手部分の歪み・損傷・破損等を著しく抑制することができるので、一箇所の被災が全システムに影響を及ぼす水道管等に代表されるライフラインに特に有用である。   As a result of the above effects, not only the pipe support structure such as the pipe support and suspension bolts, but also the piping itself, pipe connections and joints, distortion, damage, breakage, etc. can be remarkably suppressed. Is particularly useful for lifelines such as water pipes that affect the entire system.

請求項２に示す発明によれば、一般的な組式の配管支持バンドをそのまま利用することもできるので容易に且つ低コストで提供することが可能である。   According to the second aspect of the present invention, since a general assembly type pipe support band can be used as it is, it can be provided easily and at low cost.

請求項３に示す発明によれば、一般的な提灯式の配管支持バンドをそのまま利用することもできるので容易に且つ低コストで提供することが可能である。   According to the third aspect of the present invention, since a general lantern-type pipe support band can be used as it is, it can be provided easily and at low cost.

Is appropriately set according to various conditions such as the hanging angle of the left front suspension support rod 6 and the right rear suspension support rod 9 which are screwed and locked to the left engagement portion 14 and the right engagement portion 15.

左係止部１４・右係止部１５の形成構成としては、図１〜図４に示す本実施例では、バンド抱持部１１の開放両端部に連設されたバンド端部１３・１３をそのまま左係止部１４・右係止部１５として利用している。即ち、左サポート支持構成Ｌ・右サポート支持構成Ｒを有する配管吊下支持具１として、公知公用の一般的な構成の配管バンドをそのまま利用している。   In the present embodiment shown in FIGS. 1 to 4, the band end portions 13 and 13 connected to the open both end portions of the band holding portion 11 are formed as the left latching portion 14 and the right latching portion 15. They are used as they are as the left locking portion 14 and the right locking portion 15. That is, as the pipe suspension support 1 having the left support support structure L and the right support support structure R, a known and publicly-used general structure pipe band is used as it is.

１点吊下支持構成Ｎは、図５に示すように、吊りボルト３と、該吊りボルト３にタンバックルの如き吊下接続部材３１を介してバンド端部１３を接続して、バンド抱持部１１に抱持した配管Ｐを取付面２に吊下支持する公知公用の一般的な構成の配管吊下支持具１とを用いた構成を挙げることができる。   As shown in FIG. 5, the one-point suspension support structure N includes a suspension bolt 3 and a band end 13 connected to the suspension bolt 3 via a suspension connection member 31 such as a tumble buckle. The structure using the well-known public general structure piping suspension support 1 which suspends and supports the piping P hugged by the part 11 to the attachment surface 2 can be mentioned.

以上の構成を有する本発明の配管吊下支持具１は、その使用に際して図１及び図２に示すように、
先ず、図５に示す１点吊下支持構成Ｎを有する配管吊下支持具１を、取付面２に一端が固定される吊りボルト３にタンバックルの如き吊下接続部材３１を介してバンド端部１３をボルト・ナット１６により固定することで前記取付面２に吊下支持し、
次に、図３に示す左サポート支持構成Ｌを有する配管吊下支持具１を、取付面２に一端が固定され、斜め吊下げする公知公用の吊りボルトの如き左前方吊下支持杆６の他端を左係止部１４の透孔に挿通してナット６１によって螺合緊締することによって配管Ｐの左方向における斜め１点吊下支持し、
更に、図４に示す右サポート支持構成Ｒの配管支持具１を、取付面２に一端が固定され、斜め吊下げする公知公用の吊りボルトの如き右後方吊下支持杆９の他端を右係止部１５の透孔に挿通してナット９１によって螺合緊締することによって配管Ｐの右方向における斜め１点吊下支持し、
上記の左サポート支持構成Ｌを有する配管吊下支持具１と、右サポート支持構成Ｒを有する配管吊下支持具１とを、配管軸方向において、間に１点吊下支持構成Ｎを挟んだ状態で交互に繰り返して吊下配設した構成とする。かかる構成によって、１点吊下支持構成Ｎを挟んで隣接する２種類の斜め１点吊下支持構成Ｌ・Ｒを有する配管吊下支持具１・１同士が図２に示すように平面視した際に配管軸方向において対称の斜め１点吊下支持構成を有する構成となる。 As shown in FIGS. 1 and 2, the pipe suspension support 1 of the present invention having the above-described configuration is as shown in FIGS.
First, the pipe suspension support 1 having the one-point suspension support structure N shown in FIG. 5 is attached to the suspension bolt 31 whose one end is fixed to the mounting surface 2 via a suspension connection member 31 such as a tumble buckle. The part 13 is supported by being suspended from the mounting surface 2 by being fixed by bolts and nuts 16.
Next, the pipe suspension support 1 having the left support support structure L shown in FIG. 3 is fixed to the attachment surface 2 and is fixed to the left front support suspension 6 such as a publicly-known suspension bolt that is obliquely suspended. The other end is inserted into the through hole of the left locking portion 14 and screwed and tightened with a nut 61 to support the pipe P in a slanting one point in the left direction,
Further, the pipe support 1 of the right support support structure R shown in FIG. 4 is fixed to the mounting surface 2 at one end, and the other end of the right rear suspension support rod 9 such as a publicly known suspension bolt that is slanted is suspended to the right. By inserting through the through hole of the locking part 15 and screwing and tightening with the nut 91, the pipe P is supported at one point obliquely in the right direction,
The pipe suspension support tool 1 having the left support support structure L and the pipe suspension support tool 1 having the right support support structure R are sandwiched by one point suspension support structure N in the pipe axis direction. It is set as the structure arrange | positioned suspended by repeating alternately in a state. With this configuration, the pipe suspension supports 1 and 1 having two types of slanted one-point suspension support configurations L and R that are adjacent to each other across the one-point suspension support configuration N are viewed in plan as shown in FIG. In this case, the structure has a slanting one-point suspended support structure symmetrical in the pipe axis direction.

以上の構成、即ち、１点吊下支持構成Ｎを間に挟んだ状態で２種類の斜め１点吊下支持構成Ｌ・Ｒを有する配管吊下支持具１・１を配管軸方向において交互に用いて配管Ｐを吊下支持することによって、この２種類（Ｌ・Ｒ）の配管吊下支持具１が、隣接するもの同士で平面視した際に配管軸方向において対称の斜め１点吊下支持構成となるので、配管軸方向の振動負荷と配管軸直交方向の振動負荷とが同時に生じることに加えて、捻れを含む軸線回り方向に傾動・揺動する振動負荷をも生じた場合であっても、様々な方向における揺れを対称構成の２種類のサポート支持構成Ｌ・Ｒが互いに打ち消す作用効果を発揮し、揺れを収束させることができる。従って、長尺スパンや超長尺スパンにおける配管吊下支持であっても、複数個ないし多数個の配管支持具１・１・１・・・に掛かる負荷が同調して増幅されてしまうことを抑制することができ、配管支持具１に歪みや破損が生じ難いという、本発明に係る特定の２種類の斜め１点吊下支持構成による相乗効果を有している。   In the above-described configuration, that is, with the one-point suspension support configuration N sandwiched therebetween, the pipe suspension supports 1 and 1 having two kinds of oblique one-point suspension support configurations L and R are alternately arranged in the pipe axis direction. By using the pipe P to suspend and support, the two types (LR) of the pipe suspending support 1 are slanted at one point symmetrical in the pipe axis direction when viewed adjacent to each other in plan view. Because of the support configuration, in addition to the vibration load in the direction of the pipe axis and the vibration load in the direction perpendicular to the pipe axis being generated at the same time, a vibration load that tilts and swings in the direction around the axis including torsion is also generated. However, the two types of support support structures L and R having a symmetrical configuration can cancel each other in the various directions, and the vibration can be converged. Therefore, even in the case of pipe suspension support in a long span or an ultra-long span, the load applied to a plurality or a large number of pipe supports 1. It has a synergistic effect by the two specific slanted one-point suspension support configurations according to the present invention that can be suppressed and that the pipe support 1 is less likely to be distorted or damaged.

また、吊りボルト３と配管支持バンド１とによる通常の１点吊下支持構成Ｎ・Ｎ・Ｎ・・・を有する既存の配管設備に、上記した２種類のサポート支持構成Ｌ・Ｒを付加することによって本発明と同様のサポート支持構成を有する配管吊下支持具とすることもできる。   In addition, the above-described two types of support support configurations L and R are added to existing piping equipment having a normal one-point suspension support configuration N, N, N... By the suspension bolt 3 and the pipe support band 1. Accordingly, a pipe suspension support having the same support support structure as that of the present invention can be obtained.

また、図１〜図４に示す上記実施例では、バンド抱持部１１の開放両端部に連設されたバンド端部を左係止部１４・右係止部１５とした構成であるが、本発明はかかる構成に限定されず、バンド抱持部１１と同素材であって別体構成である板材をバンド抱持部１１の形成位置に溶接・融着・接着・ネジ留めの如き固着手段により止着した構成とすることもできるし、或いはバンド抱持部の一部を切起すことにより形成した構成とすることもできる。   Moreover, in the said Example shown in FIGS. 1-4, although it is the structure which made the band edge part connected with the open both ends of the band holding part 11 into the left latching | locking part 14 and the right latching part 15, The present invention is not limited to such a configuration, and a fixing means such as welding, fusing, adhering, and screwing a plate material, which is the same material as the band holding portion 11 and is a separate structure, to the position where the band holding portion 11 is formed. It can also be set as the structure fastened by, or can also be set as the structure formed by raising a part of band holding part.

更に、図１〜図５に示す上記実施例では、配管吊下支持具１の本体が半円状の２本のバンド抱持部１１を下方の蝶番式の接続部１２で接続した構成であるが、この種の配管バンドとして公知公用の構成及び素材を有する種々仕様のものを特別の制限なく用いることができ。例えば、組式構成の接続部を有する配管バンドであってもよいし、１本の環状の帯状板材から形成された提灯式の配管バンドであってもよい。   Furthermore, in the said Example shown in FIGS. 1-5, the main body of the piping suspension support 1 is the structure which connected the two semicircle-shaped band holding parts 11 with the lower hinge-type connection part 12. FIG. However, it is possible to use various types of piping bands having various publicly known configurations and materials without any particular limitation. For example, it may be a piping band having a connection portion of a combined configuration, or may be a lantern type piping band formed from one annular strip-shaped plate material.
