Description

[Detailed Description of the Invention] The present invention relates to the structure of a folding temporary ladder that is suspended along the structure of a high-rise building or the like.

The present invention will be explained with reference to an embodiment shown in the figure below. Reference numerals 11 and 12 are mounting brackets fixed to the upper and lower parts of a structure such as a high-rise building, respectively, with a required width in the horizontal direction. Metal fittings 11, 12
Ends of a plurality of flexible band members 21 and 22, such as chains or wires, are connected between them.
Next, the four corners of the landing members 31, 32 are spaced apart from each other in the vertical direction with respect to the flexible band members 21, 22 so that the landings 71, 72 provided there are staggered on both sides. are linked.

That is, the landing members 31 and 32 have landings 71 and 72 formed at one end thereof, and approximately U-shaped auxiliary frame members 51 and 52 are integrally formed at the other end,
The width is approximately the width between the flexible band members 21 and 22.

The outer corners of the landings 71 and 72 and the outer corners of the auxiliary frame members 51 and 52 are connected to the flexible band member 2.
It will be linked between 2 and 21. Furthermore, a ladder member 4 is attached to the inner edge of each of the landings 71 and 72.
1 and 42 are rotatably linked.

Furthermore, necessary handrail members 61 and 62 are attached between the flexible band members 21 and 22 and between the ladder members 41 and 42, etc., as necessary.

With the above configuration, the landings 71 and 72 are rotatably connected to each other by the ladder members 41 and 42, so that the connecting parts can be used as hinges to fold each other, and for example, they can be assembled integrally in a factory. By folding it into a compact size, it can be easily stored and transported to a work site, etc., and can be easily suspended or temporarily installed in a required structure.

Further, the flexible band members 21 and 22 connected between the upper and lower mounting brackets 11 and 12 may be continuous band members, but instead of this, each landing member 31,
Required connecting members 7 having connecting holes provided at the upper and lower ends are attached to the four corners of 32, respectively, and a connecting band member 8 of a required length is used to connect these members, so that they are connected to each other in the vertical direction. Good too. This not only improves workability but also makes assembly easier, and the levelness of each landing can be easily ensured.

Further, the ladder members 41 and 42 connected to the landings 71 and 72 may be rotatably connected to each other, but instead of this, one of the left and right ladder members 41 and 42, the one on the ladder member 41 side, may be removed. By making the other side of the ladder member 42 freely rotatable or by making one end of the ladder members 41 and 42 removable, it can be made parallel to the back side of each landing member 31 and 32 or the landings 71 and 72. The ladder member 41 or 42 can be accommodated. In this way, the volume when folded can be reduced, and storage and transportation can be easily performed.
