Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a projecting stairway landing provided on a temporary scaffold.

[0002]

[Prior art]

 When assembling a temporary scaffolding on a construction site, as shown in FIG. 5, stairs 21 for raising and lowering are always provided as climbing piers. Conventionally, when a one-span scaffolding staircase 21 is provided, temporary scaffolding 22 for landing is further assembled on each of the left and right sides of the one-span scaffolding stairway 21 for one span, and the scaffolding for a total of three spans is performed. It is common.

[0003]

[Problems to be solved by the present invention]

 In the conventional staircase 21 for scaffolding configured with 3 spans as shown in FIG. 5, not only is the temporary scaffold 22 with 2 spans for landing taken up too much space, but the number of scaffolding members is large, and the assembly work is troublesome. It costs a lot. Therefore, the object of the present invention is to easily install and install the scaffolding on the floor where the landing is to be installed, and the scaffolding can be easily and safely assembled and used with a small number of parts as a projecting type to the stairs for scaffolding with one span. Is to provide a landing.

[0004]

[Means for Solving the Problems]

 As means for solving the above-mentioned problems, the landing of the stairs for scaffolding according to the present invention is fixed to the outside of the vertical member 1a of the scaffolding building frame 1 with the fixing tools 2 and 9 as shown in the embodiments in the drawings. The pair of left and right substantially rectangular side frames 3, a plurality of horizontal handrails 6 connected substantially horizontally between the outer vertical members 4a of the pair of side frames 3, and the pair of side frames 3 It is characterized in that it is composed of a cloth plate 7 laid between the lower horizontal members 5a, and the cloth plate 7 is arranged at the upper end or the lower end of the temporary stairs of the scaffold.

According to the present invention, at least one of the pair of left and right side frames is formed on the entrance / exit frame 8 by extending the outer vertical member 4a and the inner vertical member 4b, and the fixture is provided on the side frame 3. It is composed of a clamp 2 for fastening and fixing the inner vertical member 4b to the vertical member 1a of the scaffolding building frame 1, and a hook-shaped support 9 which is hooked on the horizontal member 1b of the scaffolding building frame 1 from above. It is also characterized by

[0006]

[Action]

 The pair of left and right side frames 3 are fixed to the scaffolding building frame 1 at an upper portion thereof with a clamp 2 and at a lower portion thereof with a supporting member 9. As described above, the horizontal handrail 6 is connected between the outer vertical members 4a of the pair of left and right side frames 3 and 3 fixed to the scaffolding building frame 1, and similarly between the lower horizontal members 5a of the side frames 3. The cloth board 7 is erected to complete the landing, and the integrity and rigidity of the framework can be obtained.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which landings A and A'are installed above and below a scaffolding 21 for one span. The upper landing A has a pair of left and right side frames 3 and 3 which are attached and fixed to the outside of the vertical member 1a of the scaffolding building frame 1 by a clamp or the like 2 and an outer vertical member 4a of the pair of side frames 3 and 3. It is composed of a plurality of horizontal handrails 6 connected substantially horizontally between them and a cloth plate 7 laid between the lower horizontal members 5a of the pair of left and right side frames 3. In the lower landing A'shown in the lower left of Fig. 1, one of the pair of side frames has a vertically long rectangular shaped tall entrance with the outer vertical member 4a and the inner vertical member 4b lengthened upward. It is configured as a frame 8. People also enter and exit the lateral scaffolding through the entrance / exit frame 8.

As shown in FIG. 2, the side frame 3 is formed in a vertically long substantially rectangular shape by an outer vertical member 4a and an inner vertical member 4b, a lower horizontal member 5a and an upper horizontal member 5b, and is formed in the middle. A reinforcing material 5c is provided. The hook 7a of the cloth plate 7 is erected on the lower horizontal member 5a to form the floor surface of the landing. The outer vertical member 4a is provided with a pin-shaped handrail mounting portion 4c inwardly, and the horizontal handrail 6 is configured to be easily attached and detached by inserting the holes at both ends thereof into the pin-shaped handrail mounting portion 4c. ing. The upper part of the inward vertical member 4b is clamped and fixed to the outside of the vertical member 1a of the scaffolding building frame 1 by a fixture such as a clamp 2. In the lower part of the same inward vertical member 4b, the hook-shaped support tool 9 shown in FIG. 3 is fixed to the lateral member 1b of the scaffolding frame 1 from above and fixed to the outside of the scaffolding frame 1. There is. As shown in FIG. 3, the hook-shaped support tool 9 includes a box body 9a in which a joint portion between the inner vertical member 4b of the side frame 3 and the lower horizontal member 5a can be bolted, and a scaffold for scaffolding. It is composed of two hook-shaped hooks 9b which are hooked from above only to the cross members 1b of the scaffolding building frame 1 while avoiding the vertical members 1a of the building frame 1, and the side frame 3 is provided with the support member 9 described above. It can be easily attached and fixed simply by hooking it on the cross member 1b. In short, the worker can easily attach and fix the side frame 3 to the outside of the scaffolding building frame 1 with the attachment position of the side frame 3 as the working level by the clamp 2 and the support tool 9 described above.

FIG. 1 shows an embodiment used for a one-span scaffolding staircase 21, but as another embodiment, as shown in FIG. 4, an end portion (left end) of a multi-span scaffolding staircase is shown. The landing A, which was set up in a projecting form, will also be held. In this case as well, not only can the number of members be greatly reduced, but it can be assembled safely and easily.

[0010]

[Effects of the present invention]

 According to the landing of the scaffolding stairs according to the present invention, the landing A or A'can be installed so as to project to the outside of the one-span scaffolding staircase without installing a temporary scaffolding for the landing. Moreover, the installation work can be performed only on the floor where the landing is to be installed, and due to the small number of parts such as the side frame 3, the side rails 6 and the cloth plate 7, the scaffold stairs 21 can be easily and safely mounted. It can be assembled and used. Further, by using the entrance / exit frame 8 for the side frame, it is possible to install the entrance / exit to and from the passageway of the temporary scaffold.
