Description

[Detailed Description of the Invention] This invention relates to a building wall renovation method for attaching new exterior panels to the wall of an existing relatively old building. It is characterized by simplifying the construction, shortening the construction period, and reducing construction costs.

Conventionally, in this type of renovation work, it has been necessary to first erect scaffolding along the wall surface to be renovated.

For this reason, it may occupy the roads near the building, obstructing traffic, and it requires a lot of labor and many parts to assemble the scaffolding, so it is difficult to assemble the scaffolding and dismantle it. This takes a lot of time and money, and ends up prolonging the renovation work period and increasing the cost. Furthermore, this type of construction method does not allow for much space for the scaffolding, which poses the problem of whether the renovation work is dangerous.

This invention was made with the intention of solving the above problem.A curing sheet is stretched from the roof of the building to be renovated to the outside of the renovated wall surface, and between this curing sheet and the wall surface, A first working gondola, which has approximately the same width as the wall to be renovated, and a second working gondola, which is narrower than the first working gondola, are each suspended so as to be able to rise and fall freely, and these gondolas are used to add new material to the wall to be renovated. By attaching the exterior panels, conventional scaffolding is not required, and there is no hindrance to the vicinity of the site.Furthermore, on-site construction can be simplified, shortening the construction period and reducing construction costs. The purpose of the present invention is to provide a method for renovating a wall of a building, which is characterized in that the renovating work can be carried out safely.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an outline of the renovation method of the present invention;
FIG. 2 is a vertical cross-sectional view of the building. In the figure, 1 is a building to be renovated.
It is used as a material storage area to store materials such as new exterior panels 4 that will be lifted by. Further, a curing sheet 5 is stretched over the wall surface 1a to be renovated from the roof 2, and between this curing sheet 5 and the wall surface 18, a first work gondola 6a and a first work gondola 6a having a width approximately the same as the width of the wall surface 1a are installed. A second working gondola 6b, which is narrower than the working gondola 6a, is suspended such that it can be raised and lowered. In this case, the curing sheet 5 has a box-shaped structure attached to the lower end of a blind or net-like sheet body 5a that is suspended via a curing sheet bracket 7 that projects outward from the end wall 2a of the rooftop 2. It is made up of fixed hanging scaffolds 8 connected together, and the outer part of the wall surface 1a to be renovated is covered in a stretched manner by the weight of the fixed hanging scaffolds 8. Further, the first and second working gondolas 6a and 6b are each connected to one end of a rope 10 suspended via a gondola bracket 9 protruding outward from the end wall 2a of the store E2. At the same time, the working gondola 6a
.

It is raised and lowered to a predetermined position and held at a stopped position by a lifting means (not shown) such as a winch having a drum or the like attached to the 6bK. And in this case,
Worker A can board the first work gondola 6a and perform renovation work, and the second work gondola 6b is formed to a size that can be stored inside the first work gondola 6a. It is used for transporting materials. However, the first work gondola 6g is not necessarily operated by worker A.
In addition to accommodating equipment, it can also be used for transporting materials, and it is also possible for Worker A to board the second work truck f'ibK and carry out renovation work.

Next, to explain the procedure of the renovation work of this invention, as shown in Fig. 3, the building frame 1 of the building 1 is
Existing tile exterior wall facing bK] Drill a hole through C 11.
After doing 11..., put anchor 12 into each horde and get 1
Next, after fixing the mounting bracket 14 to the protrusion of the anchor 12 with the bolt 13, a new exterior plate 4 is brought into contact with the outer surface of the bracket 15 connected to the mounting bracket 14, and
Bracket) 15 has a screw, and a fixing device such as a rivet 16
The mounting end 4a of the exterior plate 4 is clamped and fixed between the batten 17 and the bracket 15, which are connected together, and the renovation work is completed by sequentially applying the same steps to the upper and lower surfaces of the building 1.

Note that sometimes worker A is required to make holes in the wall 1a using a drill, etc.
A reaction occurs on the working gondola 6a or 6b through 1
Since there is a risk that the work gondolas 6a and 6b may swing, a fixing device such as a suction cup or a locking hook is attached to the existing wall 1a or window, and this fixing device and the work gondola 6a,
6b, the safety level of the work will be further increased. Further, the exterior plate 4 is not limited to the embodiment shown in the drawings, but may also be a mullion, a no-mesh exterior, or a nine-type exterior.

As explained above, according to the renovation work method of the present invention, there is no need to erect scaffolding outside the wall surface 1a of the building l to be renovated, and scaffolding is not required to be installed from the rooftop 2 of the building l to the renovated wall surface 1a. Between the curing sheet 5 and the wall surface 1a, the wall surface 1a
A first working gondola 6a, which has approximately the same width as the horizontal width of Since new exterior panels 4 can be attached to the building, the preparatory stage for renovation work and the cleanup work after renovation work can be done easily and with a small number of materials, and the renovation work can be carried out safely without disturbing the vicinity of the building. Moreover, since the first working gondola 6a is approximately the same width as the wall surface, the entire wall surface can be renovated at the same time, and the first and second working gondolas 6a and 6b can be used effectively. By using it, material transportation and renovation work can be carried out continuously, resulting in excellent effects such as shortening the construction period and reducing construction costs, and the value of its use is remarkable. 0
