この考案は、鋼製足場板の端部連結金具に関す
る。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an end connecting fitting for a steel scaffolding board.
（従来の技術および問題点）
通常、鋼製足場板は、軽量化のため断面略溝形
に形成され、その長手方向両端部には連結金具が
取付けられている。(Prior Art and Problems) Usually, a steel scaffolding board is formed into a generally groove-shaped cross section to reduce weight, and connecting fittings are attached to both longitudinal ends of the steel scaffolding board.
ところで、従来この種の連結金具は、鋼製足場
板の端部に溶接によつて取付けられ、取外しが全

なだけでなく、互換性がないため、補強金具等、
他の端部金具との付け替えができず、また連結金
具のみが変形、損傷等した場合は、鋼製足場板ご
と交換しなければならず不経済であつた。 By the way, conventionally, this type of connecting metal fittings were attached to the ends of steel scaffolding plates by welding, and could not be removed at all. For this reason, not only is installation relatively troublesome, but there is no compatibility, so reinforcing metal fittings, etc.
It is not possible to replace the end fittings with other end fittings, and if only the connecting fittings are deformed or damaged, the entire steel scaffolding board must be replaced, which is uneconomical.
このほか、他の連結手段としては、端部どうし

り、能率的でないうえ、たわみ量が多く強度的に
不充分であつた。 In addition, another method for connecting is to install clamping members with a groove-shaped cross section on both sides of two steel scaffolding boards with their ends butted against each other, and tighten both clamping members with bolts. However, it takes time and effort to insert the bolt into the clamping member, making the work complicated and inefficient, and the amount of deflection is large, resulting in insufficient strength.
また足場板の設置場所が高所であり、足場板設
置の際その都度取付ける必要があり、安全上の問
題と現場での作業能率の低下の問題が生じてい
た。 In addition, the scaffolding boards are installed at a high place and must be attached each time the scaffolding boards are installed, resulting in safety issues and reduced work efficiency on site.
この考案は、以上の問題点に鑑み案出されたも

付け代えが手軽にでき、製作も簡単かつ廉価に行
うことがき、地上において取付け作業ができ、か
つ現場においては簡単にジヨイントできる取扱い
容易でジヨイント部の剛性が高い鋼製足場板の端
部連結金具を提供することにある。 This idea was devised in view of the above-mentioned problems, and its purpose is to make it easy to replace with other end fittings such as reinforcing fittings, to be easily and inexpensively manufactured, and to be able to be used on the ground. To provide an end connecting fitting for a steel scaffolding board that can be easily handled and has high rigidity at the joint part, which can be easily installed and jointed at the site.

製足場板単位での使用も可能である。(Effects of the invention) The end connecting fittings are installed by fitting them into the ends of the steel scaffolding boards and bolting them, so there is no risk of them coming off. In addition, the mounting part is formed into a box shape, and the end face on the connecting part side and the side plate are bolted to the steel scaffolding board in two directions, and the structure is such that the bolts in both directions also receive reaction force, so local deformation is less likely to occur. This increases the rigidity of the joint. Furthermore, since the connecting fittings and the steel scaffolding board can be easily attached and detached, when the connecting fittings are not needed, it can be removed and used as a unit of the steel scaffolding board.
