〔産業上の利用分野〕
本発明は主として住宅用の布基礎のコンクリート打設時
に設けられる各種配管用の孔の周囲を補強するために、
その配管用の孔を形成するためのスリーブの周囲に設け
られる配管用スリーブの円周補強材に関するものである
。[Detailed Description of the Invention] [Industrial Application Field] The present invention is mainly aimed at reinforcing the surroundings of holes for various piping provided during concrete pouring of cloth foundations for residential buildings.
This invention relates to a circumferential reinforcing material for a piping sleeve that is provided around the sleeve for forming a hole for the piping.
住宅用布基礎のコンクリートの打設時には、水道、ガス
、排水等のための貫通孔を一棟の布基礎に対し必ず数個
所穿孔する必要があり、それらの各孔径に対応した径の
紙筒からなる配管用スリーブを布基礎に直交して配設し
た後にコンクリートを打設している。When pouring concrete for residential fabric foundations, it is necessary to drill several through-holes for water, gas, drainage, etc. in each fabric foundation, and paper tubes with diameters corresponding to the diameters of each hole must be drilled. Concrete is poured after the piping sleeve is placed perpendicular to the foundation.
そこで、このスリーブで穿孔された部分は布基礎の中で
強度の弱い部分となり、スリーブ径が大きくなればなる
程、その強度上の問題が発生する。Therefore, the perforated portion of the sleeve becomes a weakly strong portion of the fabric foundation, and the larger the diameter of the sleeve, the more problems arise regarding its strength.
一般のビル建築等の梁においては、上記と同様に、空調
その他各種配管用スリーブを設けているが、この場合は
建築基準法規により、そのスリーブの周囲を鉄筋等で補
強することが義務づけられている。Similar to the above, sleeves for air conditioning and other types of piping are installed on beams used in general building construction, but in this case, building standards require that the area around the sleeve be reinforced with reinforcing bars, etc. There is.
しかしながら、住宅用の布基礎においては、スリーブ部
分の鉄筋による補強の公的な基準はなく、殆んどの現場
ではスリーブの外周の補強を行なっていないのが実情で
あるが、スリーブを設けた個所にひびが入ることが多く
、そのひび割れ部から雨水が浸透して鉄筋に錆を発生さ
せることになるので、たとえ住宅用としてもその布基礎
のスリーブ部分の補強が強く要望されている。However, in residential cloth foundations, there are no official standards for reinforcing the sleeve portion with reinforcing bars, and the reality is that the outer circumference of the sleeve is not reinforced at most construction sites, but in places where the sleeve is installed. Cracks often occur in the fabric foundation, and rainwater seeps through the cracks, causing rust on the reinforcing bars.Therefore, there is a strong demand for reinforcement of the sleeve portion of the fabric foundation, even if it is used for residential purposes.
一方、住宅用の基礎に設けるスリーブは、空中に浮ぶビ
ル等の梁と違って第５図に示すようにフーチング１のコ
ンクリ−１・の打設の後に、そのフーチング１からの立
上り部５に各種配管用のスリーブ３を設けることが多い
。On the other hand, unlike the beams of buildings, etc. that float in the air, sleeves installed on the foundations of houses, as shown in FIG. Sleeves 3 for various types of piping are often provided.
即ち、この場合、第５図のごとくフーチング１形成用の
型枠４内に鉄筋７を配設してコンクリートの打設を行な

とを別々に打設する２度打ち工法を行なっているのが殆
んどである。That is, in this case, as shown in Fig. 5, the reinforcing bars 7 are placed in the formwork 4 for forming the footing 1 and concrete is poured, and then piping paper is placed on top of the footing 1 after the concrete is poured. A sleeve 3 such as a cylinder is provided, and concrete is poured into the rising part 5, and the footing 1 and the rising part 5 are
Most of them use the double pouring method, in which they are poured separately.
そこで、このようなスリーブ３の周囲を補強する補強材
としては、スリーブ３の周囲に設ける際の位置合せが容
易で、かつ、その補強材が一度打ちにより完成したフー

置されることが必要である。Therefore, the reinforcing material for reinforcing the periphery of the sleeve 3 should be one that is easy to align when provided around the sleeve 3, and that can be placed in a stable state on top of the completed footing 1 by one shot. It is necessary for the device to be easily and economically mounted.
〔発明の目的〕
本発明は、前記従来の要請にこたえるためになされたも

提供することを目的としたものである。[Object of the Invention] The present invention has been made in order to meet the above-mentioned conventional demands, and can be easily installed in a stable state around the sleeve, and can also be reliably reinforced around the sleeve. The aim is to provide a possible and economical circumferential reinforcement for pipe sleeves.
上記の目的を達成するための本発明の配管スリーブの円

で得られることになる。In order to achieve the above object, the circumferential reinforcing material of the piping sleeve of the present invention is designed to surround a sleeve made of a paper tube or the like for piping, which is provided during concrete pouring of cloth foundations for residential buildings. It is constructed by providing an arch-shaped iron wire that is attached to the foundation reinforcing steel,
By providing this arch-shaped circumferential reinforcing material to surround the periphery of the sleeve, placing the non-circular lower part on the footing that has been poured with concrete, and attaching it to the reinforcing bar at the rising part with wire etc. , the attachment can be easily and stably carried out, and reliable reinforcement around the sleeve can be obtained at low cost.
以下図面を参照して本発明の円周補強材の実施例を説明

用いる場合の立面図である。Embodiments of the circumferential reinforcing material of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the circumferential reinforcing material of the present invention attached to the circumference of a sleeve, and The figure is a side sectional view of Fig. 1, and Fig. 3 is an elevational view showing the circumferential reinforcement of Fig. 1.
FIG. 4 is an elevational view of the case where the circumferential reinforcing material shown in FIG. 3 is used in two layers in an upside-down direction.

により取付けられている。First, as shown in FIG. 1, the circumferential reinforcing material 6 of the present invention is used when concrete is poured into a rising portion 5 perpendicular to a footing 1 that has already been concreted when concrete is being poured for a cloth foundation for a house. For this reason, sleeve 3 such as a paper tube etc.
When the sleeve 3 is disposed perpendicularly to the rising portion 5, it is provided so as to surround the sleeve 3, and is made of a welded iron wire structure formed in a semicircular arch shape as shown in Fig. 3. It is attached to the reinforcing bar 7 of the rising portion 5 with a thin wire 8 or the like.
このような円周補強材６をスリーブ３を包囲するように
取付けた後、第２図に示すごとく、この立上り部５の両
側に型枠９を配設し、コンクリート１０を打設すること
により、スリーブ３の外周に対する強度が増すことにな
り、スリーブ３全周についてのひび割れや、クラックの
発生が防止される。After installing such circumferential reinforcing material 6 so as to surround the sleeve 3, as shown in FIG. The strength of the outer periphery of the sleeve 3 is increased, and the occurrence of cracks around the entire periphery of the sleeve 3 is prevented.
この場合、本発明の円周補強材６はアーチ形に形成され
ているので、その半円形の直線部分を下にして、打設ず
みのフーチング１の上に安定した状態で載置できること
になり、その位置決め及び取付けが容易になる。In this case, since the circumferential reinforcing material 6 of the present invention is formed in an arch shape, it can be stably placed on the cast footing 1 with its semicircular straight portion facing down. , its positioning and installation become easier.
また、この円周補強材６は鉄筋７よりも細い鉄線である
が、アーチ状に形成することによりスリーブ３の外周に
対する補強強度は充分にあり、また細い鉄線で形成する
ことにより、鉄筋７を取付けてもカブリは充分とれるの
で、カブリ不足による鉄筋７及び円周補強材６の錆の発
生等の問題はなくなる。Further, although this circumferential reinforcing material 6 is a thinner iron wire than the reinforcing bar 7, by forming it in an arch shape, the reinforcing strength for the outer circumference of the sleeve 3 is sufficient. Since fog is sufficiently removed even after installation, problems such as rusting of the reinforcing bars 7 and the circumferential reinforcing material 6 due to insufficient fog are eliminated.
なお、配管用のスリーブ３がフーチング１のすぐ上でな
く、立上り部５の中間に設けられる場合には、第４図の
ごとく本発明の円周補強材６を２枚上下逆方向に重ねて
針金８等により取付けて円形とし、スリーブ３の全周を
包囲するように鉄筋７に取付ければ、完全なスリーブ３
の全周補強ができる。In addition, when the piping sleeve 3 is provided not directly above the footing 1 but in the middle of the rising portion 5, two circumferential reinforcing members 6 of the present invention are stacked upside down as shown in Fig. 4. A complete sleeve 3 can be obtained by attaching it with a wire 8 or the like to make it circular and attaching it to the reinforcing bar 7 so as to surround the entire circumference of the sleeve 3.
Can be reinforced all around.
以上に説明したように、本発明の円周補強材は、鉄線を

を確実に、かつ経済的に防止できる。As explained above, the circumferential reinforcing material of the present invention is made of iron wire formed into an arch shape, and can be produced at low cost through mass production, and can be easily attached to the periphery of the sleeve in a stable state. This has the effect of being able to reliably and economically prevent the occurrence of cracks and cranks in the outer peripheral portion of the piping sleeve.
