この考案はコンクリート梁を貫通する貫通孔の
補強装置に関する。[Detailed description of the invention] This invention relates to a reinforcement device for a through hole penetrating a concrete beam.
従来、梁にスリーブを埋設して構成した貫通孔
の部分を補強するために、様々な手段がとられて

する方法があつた。 Conventionally, various measures have been taken to reinforce the through-hole portion formed by embedding a sleeve in the beam. For example, a method of arranging a circular reinforcing bar 1 formed by connecting a plurality of concentric annular reinforcing members as shown in FIG. 1a, or a spiral reinforcing bar 2 shown in FIG. Four parallelogram reinforcing bars 3 as shown in figure a are arranged diagonally across the outer periphery of a through hole 6 of a reinforced concrete beam reinforced with upper and lower main bars 4, 4 and stirrup bars 5 as shown in b. Alternatively, there is a method in which the rectangular reinforcing bars 7 shown in FIG.
しかし、これらの方法では、いずれも貫通孔の
直径は梁丈の１／３以下に制限を受け、直径１／３以上
とする場合には別の補強方法をとる必要がある。
また、上記の方法で補強する場合、貫通孔まわり
の補強筋が多量になり、コンクリートの充填性が
低下したり、鉄筋の加工や配筋作業に多大の手間
を要する欠点があつた。 However, in all of these methods, the diameter of the through hole is limited to 1/3 or less of the beam length, and if the diameter is 1/3 or more, another reinforcement method must be used.
In addition, when reinforcing with the above method, there are disadvantages in that a large amount of reinforcing bars are required around the through hole, which reduces the filling properties of concrete and requires a great deal of effort in processing and arranging the reinforcing bars.
この考案は上記事情に鑑みなされたものであ
る。その目的は、高いせん断破壊力に耐え、梁丈
の１／３以上の直径の貫通孔を設けることができ、
補強筋の加工、配筋が容易である梁貫通孔の補強
装置を提案するにある。 This idea was made in view of the above circumstances. The purpose is to propose a reinforcement device for beam through holes that can withstand high shear breaking force, can provide through holes with a diameter of 1/3 or more of the beam length, and is easy to process and arrange reinforcing bars. be.
以下図示する実施例により説明する。 This will be explained below with reference to the embodiments shown in the drawings.

鉄板１０が取付けてある。 Fig. 4 shows a sleeve 8 made of a steel pipe used in this reinforcing device, and a reinforcing material 9 with an *-shaped cross section made by combining steel plates along the axial direction is welded to the inside, and the *-shaped reinforcement on the outer surface of the sleeve is welded. Six iron plates 10 with holes for attaching shear reinforcing bars are attached at positions corresponding to the fixed ends of the material 9.

使用した。なお、スリーブ８および補強材９の素
材として耐候性スチールを用いた。 As shown in FIGS. 5 and 6, this sleeve 8 is embedded in a reinforced concrete beam to form a through hole 6. That is, the shear reinforcing bars 12 are secured between the holes 11 of the perforated iron plate 10 and the upper and lower main bars 4, and reinforced concrete 13 is cast, thereby constructing a beam with through holes 6. Glass fiber reinforced synthetic resin (GFRP) ducts 14 at both open ends of this sleeve 8 were connected, and the through holes were used as through holes for hot air and cold air ducts. Note that weather-resistant steel was used as the material for the sleeve 8 and the reinforcing material 9.
第７、８図も前記実施例と同様にして＊形補強
材９を溶着補強した鋼管のスリーブ８を梁に埋設

径の枝管１５、２本、小径の枝管１５、４本を挿
通し、スリーブ８の両端に連結した水管１６を連
通し、貫通孔を水および冷温水管として用いた。 In FIGS. 7 and 8, a through hole 6 is formed by embedding a steel pipe sleeve 8 in which a *-shaped reinforcing member 9 is welded and reinforced in the same manner as in the previous embodiment. In this through hole 6, two large diameter branch pipes 15 and four small diameter branch pipes 15 are inserted into six spaces partitioned by reinforcing material 9, and water pipes connected to both ends of the sleeve 8 are inserted. 16 were communicated, and the through holes were used as water and cold/hot water pipes.
スリーブ内部に固着する補強材は＊形のものに
限らない。貫通孔部分が負担するせん断力の大き
さによつて×形だけであつてもよい。 The reinforcing material fixed inside the sleeve is not limited to the * shape. Depending on the magnitude of the shearing force borne by the through-hole portion, it may be only an x-shape.

Since it is constructed by embedding a reinforced sleeve with fixed or x-shaped reinforcing material, the through hole itself can ensure an extremely large shear strength, and a through hole with a diameter of 1/3 or more of the beam length can be formed. In addition, piping around the through hole in which the sleeve is embedded becomes simpler, improving workability and concrete filling performance. The through hole can be used as a flow path for conditioned air, or can be used as a flow path for cold and hot water by inserting another pipe.
