Description of the Related Art Conventionally, there have been scaffolding boards that can be expanded and contracted to suit the size of the space at a construction site, and are usually equipped with a fixing device that fixes the scaffolding boards at a desired length. As an example of this kind of fixing device, for example, a fixing pin is provided on one sliding member of a scaffolding board so as to be movable laterally, and a plurality of engagement holes are formed spaced apart in the longitudinal direction of the other sliding member. It was configured to be selectively and removably engaged with. However, it can only be fixed at a position where the engagement hole is formed, and it is necessary to align the fixing pin with the engagement hole, which is troublesome. Furthermore, a plurality of engagement holes had to be machined, and there was a large risk that the appearance would be damaged by the engagement holes. Furthermore, since one end of the fixing pin protrudes outward, there is a high risk of damage due to collision with other members during transportation or storage.

に簡単な構成であり、容易に制作できる。 The embodiment of the present invention is constructed as described above, and when it is used, both the sliding members 2 and 3 are slid relative to each other, and after the scaffolding board 1 is adjusted to extend or contract to a desired length, as shown in FIG. When the operating body 18 is pressed in the direction of arrow A, the pressing body 19 is projected in the direction of the adjacent rod members 5 due to the relative sliding between the cam groove 29 and the spring pin 30, as shown in FIG. , the friction braking member 26 is projected from the opening 32 of the rod 4 and is pressed against the side surface of the adjacent rod 5, and the frictional force between the friction braking member 26 and the side surface of the rod 5 causes both sliding members 2 ,3
relative sliding is prevented, and the length of the scaffolding board 1 is now fixed at the desired length. Next, to release the fixed state, pull out the operating body 18 in the direction of arrow B in FIG. 6, and the cam groove 29 and spring pin 3
Due to the relative sliding with respect to 0, as shown in Fig. 5,
Return to the initial release state. As described above, the fixation can be freely released by operating the operating body 18 in the axial direction, and since the pressing body 19 is pressed against the side surface of the rod material 5, the work of aligning the engagement holes as in the conventional method is not required. is not necessary, and the expansion and contraction can be adjusted steplessly.
The desired length can be easily obtained, and it is easy to operate and use. Further, there is no need for hole machining, thereby reducing manufacturing costs.Furthermore, there is no engagement hole, etc., and the appearance can be improved. Further, since the fixing device 14 is configured not to protrude from the side, collision with other members can be prevented, damage such as breakage can be prevented, and durability can be improved. Moreover, they have the advantage of being able to be used side by side. Furthermore, since the extension stopper 12 ensures an overlapping margin, safety can be improved, and the shortening stopper 13 also prevents the risk of hands or the like being caught, resulting in safety. Furthermore, it has a simple configuration and can be easily produced.
