本発明の仮設建築物用パイプクランプは構造が簡単で廉価であると共に、パイプ素子の外周面に突起物がないためシート張設等に何等の支障も生じないとともに、パイプクランプをパイプに任意の角度で固定できるようになるという大きな効果がある。また、本発明の仮設建築物用パイプクランプ及び仮設建築物用パイプ連結装置によれば複数の配置方向の異なるパイプを簡単に連結できるようになる。   The pipe clamp for a temporary building according to the present invention has a simple structure and is inexpensive, and since there is no protrusion on the outer peripheral surface of the pipe element, it does not cause any trouble in the sheet stretching and the pipe clamp can be attached to any pipe. There is a great effect that it can be fixed at an angle. Moreover, according to the pipe clamp for temporary buildings and the pipe connection device for temporary buildings of the present invention, a plurality of pipes having different arrangement directions can be easily connected.

以下図面によって本発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

本発明の仮設建築物用パイプクランプ２０は、図１及び図２に示すようにパイプ１ａの内周面に当接される当接面２１を上面に有する下側挟持部分２２と、この下側挟持部分２２の上記当接面２１から所望距離だけ離間して上記当接面２１に対向配置せしめた上側挟持部分２３と、上記下側及び上側挟持部分２２，２３を一体に保持する保持連結部分２４と、上記上側挟持部分２３に形成した垂直ねじ孔２５と、この垂直ねじ孔２５に螺合され、その下面が上記パイプ１ａの外周面に対接される締付ボルト２６とより成る。   As shown in FIGS. 1 and 2, the pipe clamp 20 for a temporary building according to the present invention includes a lower clamping portion 22 having an abutting surface 21 abutting against the inner peripheral surface of the pipe 1a on the upper surface, and the lower side. An upper holding portion 23 that is spaced from the contact surface 21 of the holding portion 22 by a desired distance and is disposed opposite to the contact surface 21, and a holding connection portion that integrally holds the lower and upper holding portions 22, 23. 24, a vertical screw hole 25 formed in the upper clamping portion 23, and a tightening bolt 26 screwed into the vertical screw hole 25 and having its lower surface in contact with the outer peripheral surface of the pipe 1a.

本発明の仮設建築物用パイプクランプ２０は上記のような構成であるから図２に示すように上記下側挟持部分２２と上側挟持部分２３間に形成される隙間間にパイプ１ａを挿入し、締付ボルト２６を締め付け、この締付ボルト２６の下端と上記下側挟持部分２２の上側当接面２１間にパイプ１ａの外周面と内周面間を挟持すれば、仮設建築物用パイプクランプ２０をパイプ１ａに対し任意の角度で固定できるようになる。   Since the pipe clamp 20 for a temporary building according to the present invention is configured as described above, the pipe 1a is inserted between the gaps formed between the lower clamping portion 22 and the upper clamping portion 23 as shown in FIG. If the clamping bolt 26 is tightened and the gap between the outer peripheral surface and the inner peripheral surface of the pipe 1a is clamped between the lower end of the clamping bolt 26 and the upper contact surface 21 of the lower clamping portion 22, a pipe clamp for a temporary building 20 can be fixed to the pipe 1a at an arbitrary angle.

本発明の仮設建築物用パイプクランプ２０を図３及び図４に示すように夫々異なるパイプ１ａ，１ａに固定せしめ、各パイプクランプ２０，２０の保持連結部分２４，２４を互いにボルト、ナット等の連結手段２５によって連結せしめれば、パイプ１ａと１ａを任意の配向角度で連結できるようになる。   As shown in FIGS. 3 and 4, the temporary building pipe clamp 20 of the present invention is fixed to different pipes 1a and 1a, and the holding connection portions 24 and 24 of the pipe clamps 20 and 20 are mutually connected with bolts, nuts and the like. If they are connected by the connecting means 25, the pipes 1a and 1a can be connected at an arbitrary orientation angle.

本発明の仮設建築物用パイプ連結装置は、図５に示すように上記図１及び図２に示すパイプクランプ２０と同一構成で、第１のパイプ１ａに固定される第１のパイプクランプ３０と、第２のパイプ１ｂに固定される第２のパイプクランプ４０と、上記第１、第２のパイプクランプ３０と４０を互いに接続する連結手段５０とにより構成する。   As shown in FIG. 5, the pipe connecting device for a temporary building according to the present invention has the same configuration as the pipe clamp 20 shown in FIGS. 1 and 2, and a first pipe clamp 30 fixed to the first pipe 1a. The second pipe clamp 40 fixed to the second pipe 1b and the connecting means 50 for connecting the first and second pipe clamps 30 and 40 to each other.

上記第２のパイプクランプ４０は図６に示すように一方及び他方のクランプ素子７、１４と、これらを一体に結合するためのボルト１０等を有する締付つなぎ手段１５とにより構成する。   As shown in FIG. 6, the second pipe clamp 40 is composed of one and the other clamping elements 7 and 14 and fastening means 15 having a bolt 10 or the like for connecting them together.

上記一方のクランプ素子７は図７に示すように挟持すべき仮設建築物用のパイプ１ｂの外周の略半周、例えば略１５０°に亘り、上記パイプ１ｂの外周面に合致する内周面２を有するよう弧状に湾曲せしめた、外周面３に突出物を有しない所定の幅の一方の板状湾曲クランプ部分４と、この一方の湾曲クランプ部分４に一体に連なる一方の板状クランプ部分５と、この一方の板状クランプ部分５に設けたねじ孔６と、上記一方の板状クランプ部分５の遊端のパイプ狭持面側に設けた凸部とにより構成する。 As shown in FIG. 7, the one clamping element 7 has an inner circumferential surface 2 that coincides with the outer circumferential surface of the pipe 1b over a substantially half circumference, for example, about 150 °, of the outer circumference of the pipe 1b for a temporary building to be clamped. One plate-like curved clamp portion 4 having a predetermined width and having no protrusion on the outer peripheral surface 3, and one plate-like clamp portion 5 integrally connected to the one curved clamp portion 4. The screw hole 6 provided in the one plate-shaped clamp portion 5 and the convex portion provided on the pipe holding surface side of the free end of the one plate-shaped clamp portion 5 are configured.

上記他方のクランプ素子１４は、図８に示すように上記一方の弧状湾曲クランプ部分４と略同一形状の他方の弧状湾曲クランプ部分８と、この他方の湾曲クランプ部分８に一体に連なる、上記一方の板状クランプ部分５より十分に長い他方の板状クランプ部分９と、上記一方の板状クランプ部分５のねじ孔６に対向する位置で、上記他方の板状クランプ部分９に設けたボルト孔１１及び上記他方の板状クランプ部分９の遊端部分に設けた、ブラケットクランプ等に取付ける取付部となる孔１２並びに、上記一方の板状クランプ部分５の遊端部分に対向する位置で上記他方の板状クランプ部分９に突設せしめた支点部１３とにより構成する。   As shown in FIG. 8, the other clamp element 14 includes the other arcuate curved clamp part 8 having substantially the same shape as the one arcuate curved clamp part 4, and the other curved clamp part 8 integrally connected to the other one. A bolt hole provided in the other plate-like clamp part 9 at a position facing the other plate-like clamp part 9 sufficiently longer than the other plate-like clamp part 5 and the screw hole 6 of the one plate-like clamp part 5. 11 and the free end portion of the other plate-shaped clamp portion 9, the hole 12 serving as a mounting portion to be attached to a bracket clamp or the like, and the other end at a position facing the free end portion of the one plate-shaped clamp portion 5. And a fulcrum portion 13 projecting from the plate-shaped clamp portion 9.

上記第２のパイプクランプ４０は、上記のような構成であるからその使用に際しては、図９に示すように一方及び他方のクランプ素子７と１４の湾曲クランプ部４と８によりパイプ１ｂを挟持し、ボルト１０をねじ孔６にボルト孔１１を介して螺合してパイプ１ｂにパイプクランプ４０を固定せしめ、このパイプクランプ４０を固定構造物等に取付用の孔１２を介して固定する。これによればパイプクランプ４０をパイプ１ｂに対し任意の角度で固定できるようになる。   Since the second pipe clamp 40 is configured as described above, when used, the pipe 1b is sandwiched between the curved clamp portions 4 and 8 of one and the other clamp elements 7 and 14 as shown in FIG. The bolt 10 is screwed into the screw hole 6 through the bolt hole 11 to fix the pipe clamp 40 to the pipe 1b, and the pipe clamp 40 is fixed to the fixed structure or the like through the mounting hole 12. According to this, the pipe clamp 40 can be fixed to the pipe 1b at an arbitrary angle.

パイプ１ｂを釈放する場合にはボルト１０をねじ孔６から緩め、支点部１３を支点として他方のクランプ素子１４を一方のクランプ素子７に相対的に傾動せしめれば、上記一方及び他方の湾曲クランプ部分４と８間に図９に示すように大きな隙間１８が形成され、パイプクランプ４０からパイプ１ｂを容易に離脱できるようになる。   When releasing the pipe 1b, the bolt 10 is loosened from the screw hole 6, and the other clamp element 14 is tilted relative to the one clamp element 7 with the fulcrum portion 13 as a fulcrum. A large gap 18 is formed between the portions 4 and 8 as shown in FIG. 9 so that the pipe 1b can be easily detached from the pipe clamp 40.

なお、図５は第１、第２のパイプクランプ３０と４０を夫々２個用い４本のパイプを互いに交叉連結せしめた例を示す。   FIG. 5 shows an example in which two pipe clamps 30 and 40 are used, and four pipes are cross-connected to each other.
