Description
【０００１】[0001]
この考案は、鉄筋の接続に使用される鉄筋の継手及び継手部材に関するもので ある。 The present invention relates to a reinforcing bar joint and a joint member used for connecting reinforcing bars.
【０００２】[0002]
従来鉄筋の端部同士を接続する継手としては、接続すべき２本の鉄筋の端部に 夫々スリーブを固着し、両スリーブの先端側に形成されたメネジ孔に１本の接続 ボルトの端部を夫々螺合させる構造のものが提案され使用されている。 この継手を使用して鉄筋を接続する場合、初め接続ボルトを一方のスリーブに 螺合させ、次いで接続ボルトを回転させて他方のスリーブのメネジに螺合させた 後、予め接続ボルトに螺合させた２つのナットを両スリーブに圧接させることに よりボルトの螺合状態を維持する。 As a joint that connects the ends of conventional rebars, sleeves are fixed to the ends of the two rebars that should be connected, and one end of the connecting bolt is inserted into the female screw holes formed at the tip of both sleeves. A structure of screwing each of these has been proposed and used. When connecting reinforcing bars using this joint, first screw the connecting bolt into one sleeve, then rotate the connecting bolt into the female thread of the other sleeve, and then screw into the connecting bolt in advance. The two nuts are pressed against both sleeves to keep the bolts screwed together.
【０００３】[0003]
上記従来の継手においては、２本の鉄筋に固着されたスリーブを１本の接続ボ ルトで接続するものであるから、接続すべき鉄筋間に芯ずれが生じている場合に は両スリーブのメネジ間にも芯ずれが生じるので、接続ボルトの捩じ込みが困難 であり、接続不能となる場合もあった。 また、接続すべき鉄筋の端部間の距離は一定であって、接続ボルトの螺合によ って鉄筋間の距離を調節することはできない。 更に、鉄筋同士の接続のみを目的としたものであって、鉄筋とＨ鋼その他の鋼 材との接続に使用することはできない。 In the above-mentioned conventional joint, since the sleeves fixed to the two reinforcing bars are connected by one connecting bolt, when there is a misalignment between the reinforcing bars to be connected, the female threads of both sleeves are connected. Since misalignment also occurs between them, it is difficult to screw in the connecting bolt, and in some cases connection becomes impossible. Moreover, the distance between the ends of the reinforcing bars to be connected is constant, and the distance between the reinforcing bars cannot be adjusted by screwing the connecting bolts. Furthermore, it is intended only for connecting reinforcing bars to each other and cannot be used for connecting reinforcing bars to H steel or other steel materials.

この考案の継手部材は、基部が鉄筋端部に固着されるスリーブの先端側に接続 ボルト装着孔を形成し、該装着孔に先端側を偏平とした接続ボルトの基端部を装 着し、前記偏平部に固着用ピンを挿通するための透孔を形成したものである。 請求項２の鉄筋の継手部材は、前記装着孔をメネジ孔としたものである。 この考案の継手は、請求項２記載の鉄筋の継手部材を二つ組合せてなり、一方 の継手部材におけるスリーブのメネジと他方の継手部材におけるスリーブのメネ ジとは逆方向としたものである。 In the joint member of the present invention, a connecting bolt mounting hole is formed at the distal end side of a sleeve whose base is fixed to the end of the reinforcing bar, and the proximal end portion of the connecting bolt having a flat distal end is mounted in the mounting hole. A through hole for inserting the fixing pin is formed in the flat portion. In the reinforcing bar joint member according to the second aspect, the mounting hole is a female screw hole. The joint of the present invention is a combination of two reinforcing bar joint members according to the second aspect of the present invention, in which the female threads of the sleeve in one joint member and the sleeve menses in the other joint member are in opposite directions.

この考案において、鉄筋同士を接続する場合には接続すべき２本の鉄筋に前記 継手部材を夫々固着し、各スリーブに螺合されたボルト同士を透孔に挿通するボ ルト等で固着する。この場合、各スリーブには個別のボルトが螺合されているの で、例え芯ずれが生じてもボルトの回転が困難になることはなく、容易に鉄筋を 接続することができる。 鉄筋と鋼材とを接続する場合には、鉄筋に前記継手部材を固着し、スリーブに 螺合されたボルトの偏平部を鋼材に当接させて、透孔に挿通するボルト等でボル トと鋼材とを固着する。 請求項３の考案においては、継手を構成する継手部材のスリーブに形成された メネジが逆方向であるから、両スリーブに螺合されたボルトを同時に同方向に回 転させるとターンバックルとして作用して鉄筋端の距離を増減することができる 。すなわち、継手のボルトを回転させることにより鉄筋間の距離を調節すること ができる。 In this invention, when the reinforcing bars are connected to each other, the joint members are fixed to the two reinforcing bars to be connected, and the bolts screwed into the sleeves are fixed to each other by a bolt or the like inserted through the through hole. In this case, since the individual bolts are screwed into the sleeves, the rotation of the bolts does not become difficult even if the core is misaligned, and the reinforcing bars can be easily connected. When connecting the reinforcing bar and steel material, fix the joint member to the reinforcing bar and bring the flat part of the bolt screwed into the sleeve into contact with the steel material. Stick and. In the invention of claim 3, since the female threads formed on the sleeve of the joint member constituting the joint are in opposite directions, when the bolts screwed into both sleeves are simultaneously rotated in the same direction, they act as a turnbuckle. It is possible to increase or decrease the distance of the reinforcing bar ends. That is, the distance between the reinforcing bars can be adjusted by rotating the bolt of the joint.

図１及び図２において、接続すべき鉄筋１、１の端部にスリーブ２の基端部が 嵌装固着してあり、前記スリーブ２の先端側にはメネジ孔３が形成してある。前 記メネジ孔３には先端部を偏平とした羽子板状の接続ボルト４の基端部が螺合し てあり、接続ボルト４の偏平部４ａには固定ボルト挿通用の透孔５が設けてある 。 この実施例の継手部材Ａ１、Ａ２は夫々前記スリーブ２と接続ボルト４とで構 成されている。そして、継手部材Ａ１、Ａ２とを組合せて鉄筋の継手Ｂを構成す る。ここで、継手部材Ａ１のスリーブ２に形成されたメネジ孔３のメネジと継手 部材Ａ２のスリーブ２に形成されたメネジ孔３のメネジとは逆方向としてある。 In FIGS. 1 and 2, a base end portion of a sleeve 2 is fitted and fixed to the end portions of the reinforcing bars 1 and 1 to be connected, and a female screw hole 3 is formed at the tip end side of the sleeve 2. The female screw hole 3 is screwed with the base end portion of a connecting plate 4 having a flat end and a flat plate, and the flat portion 4a of the connecting bolt 4 is provided with a through hole 5 for inserting a fixing bolt. is there . The joint members A1 and A2 of this embodiment are each composed of the sleeve 2 and the connection bolt 4. Then, the joint members A1 and A2 are combined to form the joint B of the reinforcing bar. Here, the female thread of the female screw hole 3 formed in the sleeve 2 of the joint member A1 and the female screw of the female screw hole 3 formed in the sleeve 2 of the joint member A2 are in opposite directions.
【０００７】 以上のように構成された継手部材Ａ１、Ａ２を使用して鉄筋１、１を接続する 場合、初めに各スリーブ２に接続ボルト４の基端部を螺合させ、次いで両継手部 材の接続ボルト４、４を同時に同方向へ回転させる。接続ボルト４、４が螺合さ れているメネジ孔３のメネジは逆方向であるから、２本の接続ボルトを同方向へ 回転させることにより接続ボルト４、４の間隔は離接するので、両接続ボルト４ 、４の偏平部４ａに形成された透孔５の位置が一致した時に回転を止め、透孔５ に固定ボルト６を挿通し、ナット７で固定する。 以上の作業により鉄筋１、１は接続される。その後、結合された２本の接続ボ ルト４、４を回転させると、メネジ孔３のメネジが逆方向であるからターンバッ クルとして機能し、鉄筋１、１の接続間隔を調整することができる。When connecting the reinforcing bars 1 and 1 using the joint members A1 and A2 configured as described above, first, the base end portion of the connection bolt 4 is screwed into each sleeve 2, and then both joint portions are connected. The connecting bolts 4, 4 of the material are simultaneously rotated in the same direction. Since the female threads of the female screw holes 3 into which the connecting bolts 4 and 4 are screwed are in the opposite directions, the distance between the connecting bolts 4 and 4 is separated by rotating the two connecting bolts in the same direction. When the positions of the through holes 5 formed in the flat portions 4a of the connecting bolts 4 and 4 coincide with each other, the rotation is stopped, and the fixing bolt 6 is inserted into the through holes 5 and fixed with the nut 7. Through the above work, the reinforcing bars 1 and 1 are connected. After that, when the two connected connection bolts 4 and 4 are rotated, since the female threads of the female thread holes 3 are in opposite directions, they function as a turn bag, and the connection intervals of the reinforcing bars 1 and 1 can be adjusted.
【０００８】 図３及び図４は上記実施例の継手Ｂの使用例である。 断面コ字状のコンクリート枠８を二つ対向させて立設した後、内腔にコンクリ ート９を打設してコンクリート柱を構成する工法において、コンクリート枠８は 上下に複数重ねる必要がある。その場合、コンクリート枠８に配設された鉄筋１ を接続する必要が生じるが、鉄筋の接続に際してはコンクリート枠８を垂直に保 持するために上下の鉄筋１、１の間隔を調整しなければならない。特にコンクリ ート枠８の両側に配設された複数の鉄筋１（図３では６本）の接続間隔を同時に 調整しなければならない。 このような場合、先に従来技術で示した継手では間隔調整ができず、また複数 の鉄筋を芯ずれなく突き合せることは事実上不可能であるから、従来の継手を使 用することができない。 この考案の継手Ｂを使用することにより、ターンバックル機能が得られるので 間隔調整が容易であり、かつ両継手部材Ａ１、Ａ２には個別の接続ボルトが螺合 されているので芯ずれが生じても接続ボルトの回転に影響はなく、固定ボルトに よる接続固定が可能である。3 and 4 are examples of use of the joint B of the above embodiment. In the construction method in which two concrete frames 8 having a U-shaped cross section are erected so as to face each other, and then concrete 9 is formed in the inner cavity, it is necessary to stack a plurality of concrete frames 8 vertically. . In that case, it becomes necessary to connect the reinforcing bars 1 arranged in the concrete frame 8, but when connecting the reinforcing bars, the spacing between the upper and lower reinforcing bars 1, 1 must be adjusted in order to hold the concrete frame 8 vertically. I won't. In particular, it is necessary to simultaneously adjust the connection intervals of the plurality of reinforcing bars 1 (six in FIG. 3) arranged on both sides of the concrete frame 8. In such a case, it is not possible to use the conventional joint because it is not possible to adjust the gap with the joint shown in the prior art and it is virtually impossible to butt together multiple reinforcing bars without misalignment. . By using the joint B of the present invention, a turnbuckle function can be obtained, so that the distance can be easily adjusted, and since individual connecting bolts are screwed to both joint members A1 and A2, misalignment occurs. Also, the rotation of the connecting bolt is not affected, and the connecting bolt can be connected and fixed.
【０００９】 上記実施例の継手部材Ａ１と、モルタル注入方式のスリーブを有する継手部材 とを組合せることも可能である。すなわち、一方の継手部材のスリーブにおいて 、接続ボルト４を挿入する孔にメネジを設けず、スリーブの側壁にモルタル注入 用の透孔を設け、両継手部材の接続ボルト４同士を固定ボルトで接続固定した後 、モルタルを注入して接続ボルト４をスリーブ２に固着する構成とするものであ る。It is also possible to combine the joint member A1 of the above embodiment and a joint member having a mortar injection type sleeve. That is, in the sleeve of one joint member, a female screw is not provided in the hole for inserting the connection bolt 4, a through hole for mortar injection is provided in the side wall of the sleeve, and the connection bolts 4 of both joint members are connected and fixed with a fixing bolt. After that, mortar is injected and the connection bolt 4 is fixed to the sleeve 2.
【００１０】 図５はこの考案の継手部材Ａ１を用いてコンクリート柱１０に配設された鉄筋 １とＨ鋼１１とを接続した使用例を示すものである。 すなわち、コンクリート柱１０に配設された鉄筋１の端部に継手部材Ａ１を予 め固着すると共に、継手部材Ａ１のスリーブ２はコンクリート柱１０に埋設して おき、スリーブ２に取付けられた接続ボルト４とＨ鋼１１とを固定ボルト１２で 接続固定してある。 図５とは逆に、柱をＨ鋼として梁をコンクリート製とした場合にも、コンクリ ート梁に配設された鉄筋とＨ鋼とをこの考案の継手部材で接続することができる 。FIG. 5 shows an example of use in which the reinforcing bar 1 arranged in the concrete column 10 and the H steel 11 are connected by using the joint member A1 of the present invention. That is, the joint member A1 is pre-fixed to the end of the reinforcing bar 1 arranged in the concrete column 10, the sleeve 2 of the joint member A1 is embedded in the concrete column 10, and the connection bolt attached to the sleeve 2 is attached. 4 and the H steel 11 are connected and fixed with a fixing bolt 12. Contrary to FIG. 5, even when the column is made of H steel and the beam is made of concrete, the reinforcing bar arranged on the concrete beam and the H steel can be connected by the joint member of the present invention.

この考案によれば、鉄筋同士を接続する場合には接続すべき２本の鉄筋に固着 される継手部材の各スリーブには個別の接続ボルトが螺合されているので、例え 芯ずれが生じてもボルトの回転が困難になることはなく、容易に鉄筋を接続する ことができる。 継手部材の接続ボルトは先端側が偏平でボルト等を挿通する透孔が形成されて いるので、接続ボルトの偏平部を鋼材に当接させて、透孔に挿通するボルト等で ボルトと鋼材とを固着することができる。 請求項３の考案においては、継手を構成する継手部材のスリーブに形成された メネジが逆方向であるから、両スリーブに螺合されたボルトを同時に同方向に回 転させるとターンバックルとして作用して鉄筋端の距離を増減することができる 。すなわち、継手のボルトを回転させることにより鉄筋間の距離を調節すること ができる。 According to this invention, when connecting the reinforcing bars to each other, since the individual connecting bolts are screwed into the respective sleeves of the joint member fixed to the two reinforcing bars to be connected, for example, misalignment occurs. Also, the rotation of the bolt does not become difficult and the rebar can be easily connected. Since the connecting bolt of the joint member is flat on the tip side and has a through hole for inserting the bolt, etc., the flat part of the connecting bolt is brought into contact with the steel material, and the bolt and the steel material are inserted with the bolt, etc. Can be fixed. In the invention of claim 3, since the female threads formed on the sleeves of the joint members constituting the joint are in opposite directions, when the bolts screwed into both sleeves are simultaneously rotated in the same direction, they act as a turnbuckle. It is possible to increase or decrease the distance between the reinforcing bar ends. That is, the distance between the reinforcing bars can be adjusted by rotating the bolt of the joint.
