Description

DETAILED DESCRIPTION OF THE INVENTION The present application relates to a construction device for a peripheral wall of a building, which is used for repairing, painting, tiling, etc. the peripheral wall of a building.

The applicant first arranged an upper elevating body and a lower elevating body vertically at a required interval on a truss attached to the roof of a building via cables, and installed a structure between the upper and lower elevating bodies. A protective net is stretched, and a working gondola is placed between the net and the wall of the building, suspended from the bulge via cables, and a hoist is used to raise and lower both the upper and lower elevating bodies. Construction of the surrounding wall surface of a building characterized by moving the netting surface along the wall surface of the building, and according to this movement, the wall surface covered with the netting is sequentially worked on by moving the work gondola up and down. proposed a method (Special Public Interest Publication 1983-
Publication No. 40312).

According to this construction method, work efficiency is significantly improved compared to the conventional method of constructing pipe scaffolding, and it is economical because it requires less protective netting on the work surface. It has the advantages of being safe by reducing the effects of wind pressure, and eliminating the need to cover the entire surrounding wall of the building until all construction work is completed.

However, according to the construction method described above, there is a problem in carrying out construction work by moving the protective net and the work gondola along the lateral direction of the surrounding wall surface of the building.

In other words, when moving the protective net and the work gondola in the lateral direction of the surrounding wall of the building, the vertical elevator and the work gondola are first lowered to the ground, and in this state, each joist and cable are moved horizontally on the roof. It is necessary to use a method in which the elevating body and the work gondola are suspended again by cables and raised from the ground by a hoisting machine, and such work is extremely complicated and labor-intensive. This has the disadvantage of significantly reducing efficiency and requiring even more complicated construction methods in cases where the ground above which the work gondola is lowered cannot be used.

Therefore, the present application further improves the above-mentioned disadvantages, and the embodiment thereof will be described in detail with reference to the drawings below. For example, the length corresponds to the width dimension of a unit work surface in the direction, and in this example, it has a length that is approximately the entire length of three work gondolas, which will be described later.

1 and a third projecting beam 12 that projects forward to suspend and support a working gondola, which will be described later. Reference numerals 13 and 14 indicate upper and lower elevating bodies for tensioning the protective net 15, and the upper elevating body 13 is located at the front and rear sides of both sides of a frame member 17, which is made of a long tube with mounting arms 16 facing inward at both ends. Winding machine 18 at each position
a, 18b, the hoisting machines 18a, 1
Cables 19a and 19b wound around 8b are supported at the front and rear positions of the first projecting beam 10, respectively.

The lower elevating body 14 is equipped with hoisting machines 21a and 21b at the front and back positions on the left and right sides of the long floor plate 20, respectively, and supports 22 are provided in the longitudinal direction at the front edge of the floor plate 20 at a required interval. The cables 23a, 23 are arranged vertically and are wound around the hoisting machines 21a, 21b.
b is supported at a predetermined position on the truck 1 via the second projecting beam 11. Each of the elevating bodies 13 and 14 are arranged so as to be able to rise and fall at the upper and lower positions of the wall surface of the building.
A protective net 15 is stretched between them. That is, the upper edge of the protective net 15 is attached in a U-shape in plan along the frame member 17 of the upper elevating body 13 by a binding line 24 or the like, and the side edge of the protective net 15 is attached to the cable 23a in the front side. and the auxiliary cables 25 with bind wires 26 or the like, and after their lower ends are appropriately fixed to the pillars 22, they are placed on the floor plate 20 of the lower elevating body 14. Further, the rear edge of the floorboard 20 is temporarily fixed to the wall surface of the building A via a stopper 28 as appropriate. Reference numeral 29 is a known working gondola which is equipped with a hoisting machine 30 in addition to a floor plate, a handrail, and a protective wall.In this embodiment, three working gondolas 29 are connected, and each working gondola 29 located on the left and right side has a hoisting machine. 30 is shown, and the cable 31 wound around the hoist 30 is supported at an appropriate position on the truck 1 via the tip of the third projecting beam 12.

In addition, the above-mentioned winding machines 18a, 18b, 21a,
21b and 30, for example, Tokuko Sho 57-3599
