2. Description of the Related Art Temporary bleachers are provided with seats, passageways and stairs by appropriately maintaining natural slopes, or by combining building frames and side frames of different heights on a flat ground, and increasing in height from the front to the rear. A basic framework to be provided was provided, and members such as detachable seats, stairs, and handrail frames were sequentially assembled on the basic framework.

In a method of assembling a temporary seat, a frame portion such as a base pipe and a connecting pipe is carried to a slope or a step surface having a poor scaffold, and is assembled sequentially on the slope or step surface.
The conventional connecting pipe generally has a length that connects four to six base pipes in the horizontal direction.

[0004] In addition, in the case of temporary bleachers, in general, the seats are not individually chairs, but are often provided with long chaises.
In many cases, mounting was fixed by bolts and nuts.

As a temporary seat, Japanese Utility Model Registration No. 2108347 states that "there is a step at an intermediate position in the front-rear direction,
The side is a temporary seat where the side frames having a horizontal horizontal bar higher than the front part are located on the left and right, and the chaises are detachably mounted on the left and right side frames. The front leg of each leg is longer than the rear leg, and the lower end of the front leg is a lower opening groove-shaped engaging portion detachable from the horizontal horizontal rod of the side frame. A temporary seat, characterized in that a lower end of the leg is a column-shaped joint portion which is detachably fitted into a column opening at an upper end of a vertical rod of a side frame. Is disclosed.

The box-shaped fitting 9 is slid and inserted from the floor plate 6 and the end of the mounting portion 81, and the inner slope of the mounting portion 81 is held by the upper slope of the opening of the box-shaped fitting 9. Then, the lower surface of the floor plate 6 is held by the lower vertical portion of the opening, the fixed wedge fitting 92 is inserted from the upper hole 90, and the head is hit, so that the outer surface of the mounting portion 81 and the floor plate 6 are pressed by the straight back portion. Then, the fixed wedge fitting 92 is fixed to the box-shaped fitting 9.

After the fixing wedge fitting 92 is fixed to the box-shaped fitting 9, it is prevented from falling out from the lower hole 91 by processing to project the tip-off preventing portion 92 a at the tip. Further, the step 92b for preventing the fixed wedge fitting 92 from coming off is prevented from coming off from the upper hole 90.

[0045]

According to the present invention, the movable jack, which is a supporting portion for supporting the base pipe, can be used even when the construction surface is an irregular surface having many irregularities such as a sloped or stepped shape for assembling a temporary seat. By moving and adjusting the height, a large temporary seat can be easily assembled in a very short time in a corresponding manner.

In addition, after assembling the basic unit of the framework at a work site where it is easy to work on a flat surface, it can be moved to a construction surface such as a slope and connected or assembled independently, so that the emergency work efficiency is improved. Also, the dismantling work is easy and possible in a short time.

Further, it is possible to easily cope with both a planar slope and a fan-shaped corner slope.

Further, the seat plate and the floor plate can be attached with one touch without using any accessory parts such as bolts and nuts. Therefore, assembly and disassembly work is easy.

Further, the step portion of the stair portion can be attached to the floor plate without using accessory parts such as bolts and nuts.

Further, since there is no gap between the floor boards or between the seat board and the floor board, and the fall prevention plate is provided in the vertical portion under the seat, the object can be dropped under the temporary viewing seat. There is no.
