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, the construction of the scaffolding and its dismantling itself are difficult because they occupy the roads near the building and obstruct the passage of the building, and the construction of the scaffolding requires a great deal of labor and a large number of parts. It took a lot of time and money to do so, which ended up prolonging the renovation work period and increasing the cost.Furthermore, the construction method for this building did not allow for much space for the scaffolding. , there were problems such as the danger involved in the renovation work.

This invention was made with the intention of solving the above-mentioned problem, and involves suspending a work/fall prevention gondola that is approximately the same width as the wall of the building to be renovated, so that it can rise and fall freely, and In order to do this, the curing sheet is supported telescopically, and a narrow work gondola is suspended above the gondola so that it can be raised and lowered, and new exterior panels are attached to the wall to be renovated using these gondolas. , it eliminates the need for conventional scaffolding, does not cause any disturbance to the vicinity of the site, can be easily constructed on site, shortens the construction period and reduces construction costs, and allows renovation work to be carried out safely. The present invention attempts to provide a method for renovating the walls of buildings, which is characterized by the following.

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. Also, the roof 2 of building 1
A gondola 6 for work and fall prevention, which has approximately the same width as the wall surface 1a, is suspended so as to be able to rise and fall via a rope 5 wound around a lifting means (not shown) such as a winch installed in the A curing sheet 7 is connected and stored in a storage chamber 6a formed on the outer surface of the gondola 6, and as the gondola 6 descends, one end of the curing sheet is fixed to a bracket 8 protruding from the rooftop 2. 7 is being gradually installed. Further, between the curing sheet 7 and the wall surface 1a at a position above the gondola 6, a working gondola 9, which is narrower than the gondola 6, is suspended so as to be able to rise and fall via a rope 5' wound around a lifting means (not shown). has been done. In this case, the curing sheet 7 is formed in a blind or net shape, and the work/fall prevention gondola 6 is suspended by a rope 5 suspended via the bracket 8 so as to be able to rise and fall freely. Worker A is mainly on board to carry out renovation work, and the work gondola 9 is suspended from a rope 5 via a bracket 10 that is shorter than the bracket 8.
', and the gondola 6
It is formed to a size that can be stored inside the container, and is mainly used for transporting materials. However, the gondola 6.9
is not necessarily used in this manner (rather than
Of course, the gondola 6 may also be used for material transportation, and the worker A may board the gondola 9 to carry out renovation work. Note that the curing sheet 7 may have one end fixed to the gondola 6 and the other end folded and stored on the roof.

Next, to explain the procedure of the renovation work of this invention, as shown in FIG. 3, first, the building frame 1 of the building 1 is
Drill holes 11 through the existing tile outer wall 1C towards b.
11..., drive the anchor 12 into each large group, and then fix the mounting bracket 14 to the protruding part of the anchor 12 with the bolt 13. At the same time, a fixing device 1 such as a screw or a rivet is attached to the bracket 15.
The mounting end 4a of the exterior board 4 is clamped and fixed between the batten 17 and the bracket 15, which are joined together by 6, 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.
There is a risk that a reaction will occur on the gondola 6 or 9 via the
Alternatively, if a fixing device such as a suction cup or a locking hook is attached to the window and the gondola 6.9 is connected to the fixing device, the safety level of the work will be further increased.

As explained above, according to the renovation work method of the present invention, the work and fall prevention gondola 6 having approximately the same width as the wall surface 1a of the building to be renovated is suspended so as to be able to rise and fall freely, and the outer surface of the gondola 6 The curing sheet 7, which is foldably connected and stored on the side, can be stretched only above the gondola 6 as it moves up and down, and between the curing sheet 7 and the wall surface 1a at the position above the gondola 6. , gondola 6
A narrower working gondola 9 is suspended so that it can be raised and lowered, and a new exterior panel 4 can be attached to the wall surface 1a to be renovated using these gondolas 6 and 9. The cleaning work can be done easily and with a small number of materials, and since the curing sheet 7 is not stretched on the floor below the renovation work site, the sunlight in the room on the lower floor will not be obstructed, and the Renovation work can be carried out safely without causing any hindrance to business operations. In addition, by effectively utilizing both gondolas 6.9, it is possible to carry out material transportation and renovation of the full width of the wall at the same time, which has excellent effects such as shortening the construction period and reducing construction costs. is obtained, and its utility value is remarkable.
