【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 is a rectangular frame whose plane is rectangular, and the widths of the rods 2 on both sides and the widths of the front and rear rods 3 are about 750 mm and about 1200 mm, respectively. On both lower surfaces of the front and rear rods 3 of the frame body 1, mounting brackets 4 having a U shape are provided facing downward. Inside the frame 1, a pair of left and right scaffolding plates 5 and 6 are provided so as to be openable and closable. The scaffold plates 5 and 6 have an area that divides the inside of the frame 1 into two substantially left and right parts, and the center part thereof is foldably connected via a hinge 5A. Rollers 7 are axially attached to both sides of the roller 6, and the rollers 7 are slidably provided in grooves 8 formed in the longitudinal direction of the inner surface of the front and rear rods 3. Incidentally, 9 is a handle provided on the upper surfaces of the scaffold plates 5, 6.

Reference numerals 11 and 12 denote plate-shaped fixtures provided on the front and rear sides of the frame 1. The one fixing tool 11 is fixed to the tip of the first support tube 13, and the other fixing tool 12 is fixed to the tip of the second support tube 14 having a cross section slightly smaller than that of the first support tube 13. There is. The base end of the second support pipe 14 is inserted into the base end of the first support pipe 13. Further, inside the first support tube 13 and the second support tube 13, there is provided a case 15 in which a coil spring 14 is housed in the longitudinal direction. A pressing shaft 16 is connected to an end portion of the coil spring 14, and the pressing shaft 16 penetrates through holes 17 provided on both sides of the case 15 and presses against the fixture 12. At the same time, the case 15 presses the fixture 11. The fixtures 11 and 12 are provided with axial projections 18 in the axial direction. The first support tube 13 and the second support tube 13A are inserted into the mounting fitting 4 and integrally arranged on one side of the frame body 1. The mounting bracket 4 is formed wider than the first support tube 13 and the second support tube 13A, and the first support tube 13 and the second support tube 13A are moved laterally to a certain extent. It can be adjusted. Further, a tightening handle 19 is screwed to the base end side of the first support tube 13. Similarly, fixing tools 20 and 21 are integrally provided on the other side of the frame 1. Reference numeral 22 is a nail hole formed in the fixtures 11, 12, 20, 21 and 23 is a groove formed in the upper surface of the first support tube 13. As for the first support pipe 13 and the second support pipe 13A, there are those based on meters and those based on scales in the steps of the architectural design of the stairs 31. For this reason, in order to be able to correspond to any of these designs, in order to correspond to the lengths of the first support tube 13 and the second support tube 13A of 1 m to 2 m and 3 to 4 lengths, The expansion and contraction of the first support tube 13 and the second support tube 13A may be about 18 cm.

Next, the operation of the above configuration will be described. First, the first support tubes 13 are set so that the fixtures 11, 12, 20, and 21 are arranged at the four corners of the frame body 1. Then, the fixtures 11 and 12 are fixed to the pair of columns 32 or beams 33 arranged near the upper part of the stairs 31 by the elastic force of the coil spring 14. At this time, if the second support tube 13A is contracted in advance so as to be inserted into the first support tube 13 and installed at a predetermined place, and then the first support tube 13 and the second support tube 13A are released. The protrusions 18 are inserted into the holes (not shown) formed in the columns 32 and the beams 33 by the elastic force of the coil springs 14 and the fixtures 11, 12, 20, 21 are crimped by the elastic force of the coil springs 14. After that, when the tightening handle 19 is rotated and screwed in, the tip of the tightening handle 19 is crimped to the second support tube 13, and as a result, the first support tube 13 and the second support tube 13A are fixed. Further, a nail (not shown) is fixed to the pillar 32 and the beam 33 through the nail hole 22. Similarly, the fixtures 20 and 21 are also fixed.

After installing the building scaffolding device in this way, when working around the stairs 31, the scaffolding plates 5 and 6 are used for the work. When going up and down using the stairs 31, slide the roller 7 in the groove 8 and bend the scaffold plates 5 and 6 through the hinge 5A as shown in FIG. After that, it can go up and down through the frame 1.

As described above, in the above-described embodiment, the fixtures 11, 12, 20, and 21 are provided at the four corners of the frame body 1, so that the columns 32 and the beams 33 near the stairs 31 are used to make desired locations. Can be fixed to. Further, since the fixing tools 11, 12, 20, 21 are biased by the coil spring 14, they can be easily attached.

Further, the frame 1 is provided with a pair of left and right scaffolding plates 5 and 6 which can be bent via a hinge 5 A so as to be openable and closable via rollers 7, so that the stairs 31 can be used to go up and down. be able to.

FIGS. 4 to 6 show a second embodiment. The same parts as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In the second embodiment, L-shaped grooves 41 are respectively formed on the outer surfaces of the front and rear rods 3 of the frame body 1, and the upper end L-shaped portions 43 of the hooks 42 serving as fittings are locked in the grooves 41. Has become. A lower end L-shaped portion 44 is also formed at the lower end of the hook 42, and the lower end L-shaped portion 44 holds the first support pipe 13 and the second support pipe 13A. The upper end L-shaped portion 43 and the lower end L-shaped portion 44 are arranged so that their directions are orthogonal to each other. Further, upper and lower two-stage grooves 45, 46 are formed on the inner surface of the front and rear rod 3, and a pair of left and right scaffolding plates 5, 6 are provided in the grooves 45, 46 so as to be slidable respectively. Incidentally, 47 is a tightening screw.

Therefore, the first support tubes 13 are set so that the fixtures 11, 12, 20, 20 and 21 are arranged at the four corners of the frame body 1. At this time, since the hook 42 holding the first support tube 13 and the second support tube 13A can move the upper end L-shaped portion 43 along the groove 41, the fixing tools 11, 12, 20, 21 positions can be freely set and fixed. Then, when going up and down using the stairs, one of the scaffold plates 5 and 6 can be opened along the grooves 45 and 46 to pass through the inside of the frame 1.

As described above, in the above embodiment, the hooks 42 are connected to the grooves 41 formed in the frame body 1, so that the positions of the fixtures 11, 12, 20, 21 can be freely set.

7 to 10 show a third embodiment. The same parts as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 7 shows a case of a staircase 31 having a landing 51. In such a case, firstly, the first support pipe 13 and the second support pipe 13A are arranged on the stairway 31 at intervals, A scaffolding device 52 for construction is arranged so that a pair of left and right scaffolding plates 5 and 6 are arranged at a desired place, and scaffolding plates 53 such as plywood are placed at other places. The scaffolding plate 53 has a crosspiece 54 fitted in the groove 23 of the first support tube 13, and a nail 55 is driven into the crosspiece 54 to be fixed.

By thus combining the scaffolding device 52 for construction and the scaffolding plate 53, the entire opening of the stairs 31 can be used as a floor scaffolding for work.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and, for example, the fixing members are arranged not only at the four corners of the frame but also in the center of the front and rear rods and fixed by a total of six fixing members. Various modifications are possible, such as may.
