も問題があつた。Prior Art Conventionally, the length of the thick timber used in concrete formwork was determined, and it was not possible to change the length according to the usage conditions. For this reason, it was necessary to prepare end pieces of various sizes according to the usage conditions, which was a time-consuming process. In view of these circumstances, various types of connecting devices have been implemented that use two end pieces and have adjustable lengths, but none of them have problems in terms of workability or reliability of connection. It was hot.

固定用レバーである。Embodiments Hereinafter, this invention will be explained based on embodiments shown in the drawings. FIG. 1 shows the first embodiment of this invention,
2 to 4 show a second embodiment. In the figure, numeral 1 is a thick piece, 2 is a holding part, 3 is a locking part, and 4 is a fixing lever.

この考案の連結装置は、みぞ形鋼からなる端太
材１を２本立設し、互いのウエブ面を当接して角
筒状の包持部２で両端太材をホールドし固定用レ
バー４により接合するものである。 The connecting device of this invention consists of two thick end pieces 1 made of groove-shaped steel that are erected, their web surfaces abutting each other, and a rectangular tube-shaped holding part 2 holding the thick end pieces 2, and a fixing lever 4 being used. It is meant to be joined.

包持部２は角断面の中空鋼又は帯状の鋼板を角
筒状に加工したものから形成され、断面方形状で
ある。第２実施例においては固定用レバー４の回

バー４を挾持するように構成した。 The holding part 2 is formed from hollow steel having a square cross section or a strip-shaped steel plate processed into a square tube shape, and has a square cross section. In the second embodiment, in order to expand the rotation range of the fixing lever 4, the holding part has a C-shaped cross section and a mounting piece 5 is provided, and the fixing lever 4 is sandwiched between the mounting pieces 5. did.

は２本の端太材を連結する際、固定用レバーの先
端部が端太材のウエブ面を押圧し易くするためで
あるが、先端部の応力集中を防ぐこと及び取手の
安全性を増すこと等も兼ねている。 A fixing lever 4 is rotatably attached to the holding part 2 via a locking part 3. In the embodiment, a pin is used as the engaging portion. The fixing lever 4 has a tip and a handle, and the tip is located inside the holding part, and the length from the holding part to the web surface of the cut piece is slightly larger than the flange width of the cut piece. long. The tip portion and the attachment portion are L-shaped, and the ends and corner portions are rounded. The reason for forming the R is to make it easier for the tip of the fixing lever to press the web surface of the end piece when connecting two end pieces, but it also prevents stress concentration at the end and the handle. It also serves to increase safety.

また、連結する２本の端太材には、ウエブ面が
互いに噛合うように長手方向に沿つて波形の凹凸
を設けておけば、接合はより確実なものとなる。 Further, if the two end members to be connected are provided with wave-shaped irregularities along the longitudinal direction so that the web surfaces mesh with each other, the joining becomes more reliable.

考案の効果この考案は以上の構成よりなり、この考案によ
