【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、単管足場等においてその構成部材である各
管体の上下縦方向および左右横方向への連結用に使用さ
れる摩擦形管体用継手金具に関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a friction type tube used for connecting vertical and horizontal and horizontal directions of the respective tube bodies which are the constituent members of a single tube scaffold or the like. The present invention relates to a body joint fitting.
従来この種の継手金具としては、連結すべき両管体の連
結端部内に挿入される一対の連結支持体と、この両連結
支持体を略中央部において束ねている基部と、この基部
を貫通して一方の連結支持体に螺合している固定ボルト
とからなるものが一般に知られている。Conventionally, as this type of joint fitting, a pair of connecting supports inserted into the connecting ends of both pipes to be connected, a base portion that bundles both connecting support bodies at a substantially central portion, and a penetrating base portion. It is generally known that the fixing bolt is screwed to one of the connecting supports.
なおこの継手金具による連結作業は、固定ボルトを螺入

とで発生する固定ボルトと一方の連結支持体との螺合作
用によって、管体内となっている両連結支持体の間隔を
拡げて管体内面へ押圧させる。The connecting work using this joint fitting is performed by screwing a fixing bolt and bringing the screwed end into contact with the other connecting support body by a screwing action between the fixing bolt and one connecting support body. The space between the two connecting supports in the pipe body is expanded and pressed against the inner surface of the pipe body.
そしてこのことで発生する連結支持体と管体内面との摩
擦力によって連結支持体と管体とを固定し、連結支持体
を介しての両管体の連結を行うものである。Then, the frictional force between the connecting support body and the inner surface of the tube generated by this causes the connecting support body and the tube body to be fixed, and the two tube bodies are connected via the connecting support body.
しかしこの従来の継手金具の両連結支持体は、略中央部
の基部および固定ボルトで支持されているだけなので、
両連結支持体の両端部が略中央部を支点として揺動しガ
タつくことがある。However, since both connection supports of this conventional joint fitting are only supported by the base part and the fixing bolt in the substantially central part,
Both ends of both connection support bodies may swing and rattle around a substantially central portion as a fulcrum.
そのため両連結支持体の管体内への挿入作業が困難とな
って面倒なものになることがある。また両管体の連結状
態が十分とならずに連結が強固に行われなくなるという
問題点があった。Therefore, the work of inserting the two connecting supports into the pipe body may become difficult and troublesome. In addition, there is a problem that the two tubes are not sufficiently connected to each other so that the two tubes cannot be firmly connected.
この考案は前述した事情に鑑みて創案されたもので、そ
の目的は管体の連結時においてガタつくことなく、管体
内への挿入を容易に行えると共に両管体を強固に連結す
ることのできる継手金具を提供することにある。The present invention was created in view of the above-mentioned circumstances, and the purpose thereof is to be able to easily insert the pipes into the pipe body without rattling at the time of connecting the pipe bodies and to firmly connect both pipe bodies. It is to provide a fitting.
この考案によれば両管体の連結端部内に挿入される一対
の連結支持体間の一端側および他端側部に、両連結支持
体へ当面する固定板を設けることとする。According to the present invention, the fixing plates facing the two connection supports are provided at one end side and the other end side between the pair of connection supports inserted into the connection ends of both pipes.
そして固定ボルトを螺入して管体内面に当接させるべく
両連結支持体の間隔を拡げても、両固定板による両連結
支持体への当面状態を維持できるように構成して、両固
定板で両連結支持体の揺動によるガタつきを防止できる
ようにしたものである。Then, even if the fixing bolt is screwed in and the space between the two connecting supports is expanded so that they come into contact with the inner surface of the pipe, the two fixing plates are configured to maintain the immediate state of the connecting plates. The plate prevents rattling due to the swinging of both connection supports.

よって両連結支持体3,3の間隔が拡がり、両連結支持体
3,3が両管体2,2の内面に押圧する。（第６図参照） そして両連結支持体3,3との摩擦力によって両管体２、
２が固定され、両連結支持体3,3を介しての、即ち継手
金具１による両管体２、２の連結作業が完了する。With the joint fitting 1 having such a structure, both pipes 2, 2
In order to connect them, first, as shown in FIG. 4, insert the both connection supports 3,3 into the connection ends of the pipes 2,2 with the space between the connection supports 3,3 narrowed. To do. (See FIG. 5) Next, the fixing bolt 4 is screwed. Fixing bolt 4 at this time
Since the pressing member 7 attached to the tip of the pressing member faces the pressure receiving inclined surfaces 5b of both fixing plates 5 and 5, screwing is prevented, so that the fixing bolt 4 and one connecting member 3 are screwed together. Depending on the application, the space between both connection supports 3, 3 is expanded, and both connection supports
3,3 press against the inner surfaces of both pipes 2,2. (Refer to FIG. 6) Then, due to the frictional force between both the connecting supports 3,3, the two pipes 2,
2 is fixed, and the connecting work of both pipes 2 and 2 through both connecting supports 3 and 3, that is, by the fitting 1 is completed.
なおこの連結作業時において、第５図で示したように管
体２内に両連結支持体3,3を挿入する時には、両固定板
5,5の支持傾斜面5a,5aが両連結支持体3,3の突部3a,3aの
傾斜面に当面しているので、両連結支持体3,3端部のグ
ラつきがなくスムーズに行える。In addition, at the time of this connecting work, when both connecting support bodies 3, 3 are inserted into the pipe body 2 as shown in FIG.
Since the supporting inclined surfaces 5a, 5a of 5, 5 are in contact with the inclined surfaces of the protrusions 3a, 3a of both the connecting supports 3, 3, there is no glaring at the ends of both the connecting supports 3, 3 and there is smoothness. You can do it.
また第６図で示したように両連結支持体3,3の間隔が拡
がっても、固定ボルト４が螺入することで押圧部材７が
固定板５、５の受圧傾斜面5bを押圧して固定板5,5を連

支持傾斜面5a,5aと両連結支持体3,3の突部3a,3aの傾斜
面との当面状態が維持される。なおこの時にバネ部材８
は伸長状態となっている。Further, as shown in FIG. 6, even if the distance between the two connecting supports 3 is widened, the fixing bolt 4 is screwed into the pressing member 7 to press the pressure receiving inclined surface 5b of the fixing plates 5 and 5. Since the fixed plates 5 and 5 are moved toward the end of the connecting support body 3, the supporting inclined surfaces 5a and 5a of the fixing plates 5 and 5 and the inclined surfaces of the protrusions 3a and 3a of both connecting support bodies 3 and 3 are separated. The current state is maintained. At this time, the spring member 8
Is in a stretched state.
ここで両支持傾斜面5a,5aが先細り状に、また両突部3a,
3aの傾斜面がすぼみ状に形成されているので、当面状態
が強固に維持される。Here, both support slopes 5a, 5a are tapered, and both projections 3a, 5a
Since the inclined surface of 3a is formed in a concave shape, the current state is firmly maintained.
そのため両連結支持体3,3の両端部がグラつくことがな
く、管体2,2の内面への押圧力を両連結支持体3,3の全長
にわたって与えることができて、両管体2,2を強固に連
結できる。Therefore, both ends of both the connecting supports 3 and 3 do not grind, and the pressing force to the inner surface of the pipes 2 and 2 can be given over the entire length of the two connecting supports 3 and 3, and , 2 can be firmly connected.
さらにこの両連結支持体3,3による両管体2,2内面への押
圧時には、係止片3cの鋸歯状部が管体2,2内面に押圧係
止するので、摩擦力が増大して両管体2,2をより強固に
連結させることができる。Furthermore, when the inner surfaces of the two pipes 2, 2 are pressed by the two connecting supports 3, 3, the serrated portion of the locking piece 3c presses and locks the inner faces of the pipes 2, 2, thus increasing the frictional force. Both pipe bodies 2, 2 can be connected more firmly.

への当面状態が解除される。On the contrary, when releasing the connected state of the two pipes 2, 2, the fixing bolt 4 is screwed out. At this time, the pressing state of the fixing plates 5 and 5 against the pressure receiving inclined surface 5b by the pressing member 7 is released, and at the same time, both fixing plates 5 and 5 are contracted by the spring member 8 so that the bolts 4
By moving to the side, the state in which the supporting inclined surface 5a is in contact with the inclined surface of the protrusion 3a is released.
そしてこのことにより、両連結支持体3,3の全長にわた

連結は解決される。The effects of the present invention are as follows. A pipe for connecting two U-shaped connecting supports by mechanically expanding the connecting supports by screwing a fixing bolt into the connecting support and a fixing plate to form a wedge-shaped mechanism. The connection support is crimped to the inner surface of the body to achieve the connection of the tubes. At this time, the pressure-bonding surface is a part of the cylindrical surface, has a predetermined length in the longitudinal direction, and makes a large surface contact. In addition, the end of the U-shaped connection support body is formed in a sawtooth shape in the longitudinal direction, and the sawtooth portion also digs into the inner surface of the tube body to be joined, and a strong frictional force is obtained to obtain a stable tube body. A bond is obtained. On the contrary, when the fixing bolt is screwed out, the fixing plate is attracted by the wedge mechanism and the spring member, and the connection support body is easily contracted, so that the connection of the pipe bodies is solved.
