険でもあつた。[Technical background of the invention and its problems] Conventionally, for example, when constructing a general house,
Interior work for stairwells and various types of atriums is carried out by temporarily erecting appropriate scaffolding because the work support surfaces are stepped or low. In particular, installation in these locations is troublesome due to the narrow space, such as installing scaffolding boards on stepladders, or installing scaffolding boards on stair handrail walls and window frames. Even if installed, the work surface was extremely narrow, and in such a narrow work area, workability was poor and the danger was great. Furthermore, when a large work surface is required in a staircase, atrium, etc., it is extremely dangerous to simply place assembled scaffolds adjacent to each other unless they are securely connected.

At the tip of the handle shaft, there is an engagement protrusion that is not larger than the internal width of the engagement recess, has a width greater than the gap between the engagement edges, and has a vertical width smaller than the gap between the engagement edges. This consists in that a pull-restricting protrusion is attached to the rear surface of the upper wall of the straddle piece, with which the handle gripping operation part comes into close contact when the engaging protrusion is engaged with the engaging recess. .
[考案の実施例]
以下、図面を参照してこの考案の実施例を説明

るものである。 That is, the structure is such that the support members 41 of the standard frames 40 adjacent to each other in the left and right direction are arranged adjacently, and a spanning piece 91 having a substantially groove-shaped cross section is formed to straddle each other, and the support members 41 A handle 93, which can be rotated from the outside, is inserted into a pair of left and right rotation holes 92 drilled in the upper wall of the straddling piece 91 at positions corresponding to the engagement recesses 2 in the figure. death,
At the tip of the shaft portion of the handle 93, an engagement member is provided which has a width not larger than the internal width of the engagement recess 2, a width greater than the gap between the engagement edges 3, and a vertical width smaller than the gap between the engagement edges 3. A mating protrusion 94 is provided in a protruding manner, and the upper wall of the covering piece 91 straddles the pull regulating protrusion 95 with which the grip operation portion of the handle 93 comes into close contact when the engaging protrusion 94 is engaged into the engaging recess 2. It is attached to the back.

成してある。 The engaging protrusion 94 is cut into an arc shape so that the corner in the rotation direction smoothly slides into contact with the inner surface of the side part of the engaging recess 2, and also prevents engagement from the outside of the connecting fitting 90. In order to visually confirm the presence or absence of the engaged state and to ensure safety, these are arranged orthogonally to each other so that the engagement protrusion 94 engages with the engagement recess 2 when the grip operation section of the handle 93 is positioned in the vertical direction. It is located. Furthermore, the end of the pull regulating protrusion 95 resists the pull resistance when the gripping operation portion of the handle 93 itself is placed on the pull regulating protrusion 95 and the engagement protrusion 94 engages with the engagement recess 2. It is formed into a sloping surface that gradually becomes higher from the end toward the center so that it can be climbed on.

合縁3内縁に係合させればよいものである。 When this is used, the adjacent struts 41 are mutually connected.
With the handle 93 facing sideways, straddle it with the straddle piece 91 to insert the engagement protrusion 94 into the engagement recess 2, and then rotate the handle 93 90 degrees downward. What is necessary is to engage the engagement protrusion 94 with the inner edge of the engagement edge 3 within the engagement surface 1.
また、80は、ジヤツキベース10上に組上げ

相互を確実に連結することができるものである。[Effects of the invention] Therefore, as described above, this invention forms a straddling piece 91 having a generally groove-shaped cross section that straddles the struts 41 of the assembled scaffold when they are arranged adjacent to each other. A pair of left and right rotation holes 92 are drilled in the upper wall of the straddling piece 91 at positions corresponding to the engagement recesses 2 having the engagement edges 3 in the openings of the support members 41.
A handle 93 that can be rotated from the outside is inserted into each of the handles, and a handle 93 that is not larger than the inner width of the engagement recess 2 and has a gap between the engagement edges 3 is inserted at the tip of the shaft portion of the handle 93. An engaging protrusion 9 having a larger width and a vertical width smaller than the gap between the engaging edges 3
4 protrudes, so the struts 41 of the assembled scaffolds are straddled by the straddling pieces 91 when they are placed adjacent to each other, and the engaging protrusions 94 inserted into the engaging recesses 2 are rotated by the handle 93. By engaging with the engaging edge 3 through a dynamic operation, the strut members 41 are placed adjacent to each other.
They can be reliably connected to each other.

こともないのである。 At this time, a pull regulating protrusion 95 with which the gripping operation part of the handle 93 comes into close contact when the engaging protrusion 94 is engaged into the engaging recess 2 is attached to the back surface of the upper wall of the straddling piece 91. Coupled with the fact that the mating protrusion 94 engages with the mating edge 3, the strut material, 4 can be removed simply by operating the handle 93.
1 to the side of the straddling piece 91, it is securely fixed and will not be separated by external force or other forces.
