有用である。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a member connecting device for temporary scaffolding and the like used in construction. INDUSTRIAL APPLICABILITY The present invention is useful as a connecting device for connecting a vertical pipe and a horizontal or diagonal horizontal stay.

に難点がある。(Prior art) Conventionally, as a device for connecting a vertical pipe and a horizontal stay, Japanese Patent Laid-Open No. 51-61139 and Japanese Patent Publication No. 54-3 have been proposed.
There is one described in Japanese Patent No. 6407. The former is connected by inserting a wedge attached to the tip of the horizontal stay into the socket of a socket member welded to the circumferential surface of the vertical tube. Since this method integrally connects the horizontal stay and the wedge, the number of parts can be reduced, but there are drawbacks to the effort involved in welding the socket member to the vertical pipe and the strength of the welded part.

には、それだけ多数の横ステーを使用し、また筋交いを
不可欠とする。In addition, the fixing force that prevents the rotational force of the horizontal stay in the horizontal plane centered on the school is weak, so from the perspective of the assembled scaffolding, these connecting parts, which are nodes, have the property of smooth joints. It can be said. Therefore, in order to make the scaffolding strong, a large number of horizontal stays and bracing are essential.

いう欠点がある。The latter involves welding a flange-like circular ring to the vertical pipe, fixing a side-shaped connecting part that straddles the circular ring on the horizontal stay, and inserting a wedge across the through hole provided in the circular ring and the connecting part. It was then connected. Although this is advantageous in that a plurality of horizontal stays can be connected to one circular ring, the fixing force that prevents the above-mentioned rotational force of the horizontal stays is still weak. In other words, the only parts that receive this rotational force are the contact parts between the stem and the through-hole, and the vertical pipe and the connecting part, and the span between these contact parts is short, and the vertical pipe is usually a circular pipe. Therefore, the abutting portion between this and the connecting portion does not act effectively against the above-mentioned rotational force. Therefore, since this connecting part still has a glide-like nature, it has the disadvantage that a large number of transverse stays and braces are required to strengthen the scaffolding.

In this device, the connecting portion is fitted over the ring, and a wedge is inserted across the through holes provided in the ring and the connecting portion to connect the ring. The side portion and the U-shaped deep portion of the connecting portion come into contact with each other to restrict rotation of the horizontal stay in a horizontal plane.
(実 施 例)
第1図において、■は仮設足場等の構成部材である垂直
方向の縦管であって、これら縦管1は、通常、金属製の
円管が用いられ、一定の間隔をおいて多数並設される。(Example of implementation) In Fig. 1, ■ indicates vertical pipes that are components of temporary scaffolding, etc. These vertical pipes 1 are usually circular metal pipes, and are spaced at regular intervals. A large number of them are arranged side by side.
各縦管1は、水平方向に架設した横ステー2によって連
結、支持されており、必要な強度、形状、寸法を有した
構造物に組立てられている。また横ステー2は、対角線
状に斜め方向に架設される場合もある。Each vertical pipe 1 is connected and supported by horizontal stays 2 installed horizontally, and assembled into a structure having required strength, shape, and dimensions. Further, the horizontal stays 2 may be installed diagonally in an oblique direction.

によって固着している。Now, the connection device between the vertical tube 1 and the horizontal stay 2 is constructed as follows. A suitable number of flange-like rings 3 are fixed to the vertical pipe 1 by welding or the like, while connecting portions 4 having substantially U-shaped sides are fixed to both ends of the horizontal steel 2 by welding or the like.

なるようにして溶接により固着されている。In FIGS. 2 and 3, the ring 3 has a regular octagonal outer circumferential shape, and a round hole 5 is provided in the center of the ring 3, and the vertical tube 1 passes through the round hole 5. A rectangular through hole 7 is provided between each side portion 6, 6, . The rings 3 are manufactured, for example, by press punching a metal plate, and are fixed by welding at a fixed position on the vertical tube 1 so that each ring 3 is at the same angular position.

件を満たす大きさ、位置とされている。On the other hand, the connecting portion 4 is manufactured by press molding or forging to have a substantially trapezoidal shape in plan view and a substantially U-shape in side view, and a pattern 11 to be described later is inserted into the middle of both side plate portions 8.8. A rectangular through hole 9.9 is provided. U-shaped deep part,
In other words, the center plate portion 10 connecting the side plate portions 8°8
The length from the inner surface 10a to the tip 8a of the side plate 8 is approximately the same as the length from each side 6 of the ring 3 to the surface of the vertical tube 1. This connecting part 4 is fitted over the ring 3, and in that state, the wedge 11 is inserted across the respective through holes 7, 9.9.
is inserted. As is clear from FIG. 3, the side of the through hole 9 of the side plate 8 that is closer to the tip 8a is in contact with the pattern 11, and the side of the through hole 7 of the ring 3 that is closer to the side 6 is in contact with the pattern 11. Each through hole 7, . 9. .. 9 has a size and position that satisfy this condition.

しようとしてもそれを阻止する強い固定力が作用するの
で、この連結部分は剛節的な性質を有しているというこ
とができる。Since the ring 3 and the connecting portion 4 are attracted to each other by the pattern 11, the tip portion 8a and the surface and inner surface 1 of the vertical tube 1
0a and the side portion 6 are in contact with each other or in a state close to contact. That is, if the dimensional accuracy of the ring 3 and the connecting part 4 is high, they will come into contact at the same time, and if the dimensional accuracy is low, they will come into contact after some distortion occurs in each part, or they will come into contact with a very small gap. Therefore, the rotation of the horizontal stay 2 in the vertical plane is restricted by the contact between the vertical tube 1 and the tip 8a, and the rotation in the horizontal plane is restricted by the contact between the side part 6 and the inner surface 10a. regulated by. Therefore, even if the horizontal stay 2 tries to rotate in any direction, a strong fixing force is applied to prevent it from rotating, so this connecting portion can be said to have rigid joint properties.
上述の実施例において、辺部6と内側面10aとは必ず
しも均一に当接する必要はなく、内側面10aの両端に
近い位置の少なくとも三箇所で当接すればよい。したが
って、内側面10aをコ字状内方の中央部が凹状となる
弯曲形に形成してもよく、また内側面10aの両端にコ
字状内方へ突出する突起を形成することとしてもよい。In the above-described embodiment, the side portion 6 and the inner surface 10a do not necessarily need to abut uniformly, but may abut at at least three locations close to both ends of the inner surface 10a. Therefore, the inner surface 10a may be formed into a curved shape in which the center part of the inner side of the U-shape is concave, or protrusions that project inward in the U-shape may be formed at both ends of the inner surface 10a. .
また、通常用いる足場においては、横ステー2の垂直面
内での回転力は生じない場合が多いので、貫通孔9から
先端部8aまでの長さを短くして先端部8aが縦管1に
当接しないようにしてもさしつかえないことも多い。In addition, in normally used scaffolding, rotational force is not generated in the vertical plane of the horizontal stay 2 in many cases, so the length from the through hole 9 to the tip 8a is shortened so that the tip 8a is attached to the vertical tube 1. In many cases, it is okay to avoid contact.
したがって、そのようにすると、リング3及び接続部4
の寸法精度が低い場合でも、辺部6と内側面10aとが
充分に強く当接し、横ステー2の水平面内での回転を強
く規制できるとともに、がたつきをなくすことが可能で
ある。Therefore, by doing so, the ring 3 and the connecting part 4
Even when the dimensional accuracy of the side portion 6 and the inner surface 10a are sufficiently strong, it is possible to strongly restrict the rotation of the horizontal stay 2 in the horizontal plane and eliminate rattling.
以上の説明では、リング3に一個の横ステー2を連結し
た場合について述べたが、他の辺部6・・・9と貫通孔
7・・・を利用して複数の横ステーを連結することはも
ちろん可能である。この場合に、連結された各種ステー
は水平面内で互いに一定の角度を保持した状態となるの
で、連結して組立てられた構造物は強固なものとなる。In the above explanation, the case where one horizontal stay 2 is connected to the ring 3 has been described, but it is also possible to connect a plurality of horizontal stays using the other sides 6...9 and the through holes 7... Of course it is possible. In this case, the connected stays are held at a constant angle to each other in the horizontal plane, so that the connected and assembled structure becomes strong.
上述の実施例においては、リング3を正八角形状とした
が、他の形状でも可能である。例えば第4図に示すごと

二個の横ステーを連結可能としたもの、さらには三角形
状、六角形状または円形の一部を直線状に切欠いた形状
のものとしてもよい。In the embodiments described above, the ring 3 has a regular octagonal shape, but other shapes are also possible. For example, as shown in Fig. 4, a rectangular shape with a rounded shape that allows four horizontal stays to be connected, as shown in Fig. 5, a rectangular shape that allows two horizontal stays to be connected; Furthermore, it may have a triangular shape, a hexagonal shape, or a shape in which a part of a circle is cut out in a straight line.
また、上述の実施例では、先端部8aが縦管1と当接す

い。この場合には、先端部8aは補強筒12と当接する
から補強筒12の肉厚を適切に選んでおけば充分な強度
を得ることができる。Further, in the above embodiment, the tip portion 8a contacts the vertical tube 1, but if the vertical tube 1 is thin, the abutting portion of the vertical tube may cave in and be deformed. Therefore, in such a case, as shown in FIG.
and the vertical pipe 1 may be fixed together by welding or the like. In this case, since the tip portion 8a comes into contact with the reinforcing tube 12, sufficient strength can be obtained by appropriately selecting the wall thickness of the reinforcing tube 12.

。In the above description, a case has been described in which the horizontal stay 2 is installed horizontally, but it is of course also possible to install it diagonally. In that case, the connecting portion 4 may be attached so that its tip 8a is perpendicular to the longitudinal direction of the horizontal stay 2, and the connecting portion 4 may be connected with a pin in order to variably adjust the oblique angle of the horizontal stay 2. . In this case, the connecting portion is connected to the side portion 6 and the through hole 7 located at a position perpendicular to t with respect to the installation direction of the horizontal stay.

It has a strong fixing force and rigidity, and can be made into a strong scaffold even with a small number of horizontal stays. Therefore, the number of horizontal stays can be reduced and the types of horizontal stays can be reduced accordingly by omitting braces, so that the labor and cost for assembling the scaffold can be significantly reduced.
