Description

[Detailed description of the invention] This invention relates to a method for renovating the exterior walls of an existing building.

In general, buildings, condominiums, and other buildings made of steel or reinforced concrete have a long service life, but over a long period of time, their outer walls become old and look shabby.
The building will have to be renovated due to the deterioration of its appearance. For example, when it comes to painted exterior walls, the painted surface becomes stained, discolored, or faded, and when exposed to oxygen, the paint peels off and must be repainted, and tiled exterior walls In such cases, the tiles may peel off and fall, which is dangerous, so the tiles must be replaced. However, repainting and retiling involved the entire exterior wall surface, which required a great deal of effort.

This invention was made by focusing on the above points, and it is possible to attach the base material to the outer wall of an existing building while leaving it as it is, or to remove the outer wall of the existing building and expose the existing base material. A square mullion is installed on the outer surface of the existing building at predetermined intervals in a continuous manner in the vertical direction, and a rectangular frame is formed by combining this mullion with horizontal transfer [7. By retaining window materials, wall materials, etc. to form a new external wall,
To provide a method for renovating the outer wall of an existing building by which the outer wall can be easily renovated and the outer wall looks good after the renovation.

Hereinafter, the method for renovating the exterior wall of an existing building according to this invention will be described in the first section.
This will be explained with reference to the examples shown in FIGS. First, the bases 3 and 4 are attached to the outer wall 2 of the existing building 1. In this case, the tiles 5 are attached to the outer wall 2 of the existing building 1, and the base materials 6 and 4 are attached to the outer wall 2 while the tiles 5 are attached. However, this is not limited to this example. For example, if an existing building is connected to the main body of the building through [7, base H, 1. When a curtain wall or other external wall is installed in one place, the curtain wall or other external wall may be removed to expose the existing base. Also - base material 6.4 k:1
It is not limited to the one shown in the figure, but various shapes and structures can be adopted.

Next, continuous 1'' (vibe-shaped mullions 6) are provided in the longitudinal direction at predetermined intervals on the outer surface of the existing building 1 through the two bases 3. The pipe-shaped outer part (11 parts (A7) and the inner part 8 made of steel plate and bent into a pipe shape can be freely connected with connecting pieces 9 and 10 that protrude from both the inner and outer parts of the former part 7.8. In addition, since the inner member 8 can be bent to any size in advance at the factory, it can be bent according to the location conditions of the existing building 1, such as when the space from the outer surface of the existing building 1 to the site boundary is narrow. It is possible to easily set the expected dimensions according to the expected dimensions.In addition, this inner member 8 is not necessarily required, for example, if an existing building has an external wall formed of a curtain wall using shaped steel material, the inner member 8 is not necessarily required. Alternatively, the outside member 7 may be attached directly to this shaped steel material.In this case, the shaped steel material remains as it is, so the outer wall can be formed at approximately the same position as the previous curtain wall. becomes.

Next, the horizontal branch 11 is combined with the mullion 6 and the rectangular frame 12 is assembled.
form. Like the mullion 6, this side branch 11 consists of an outer member 13 made of aluminum extrusion and an inner member 14 made of steel plate. A through member 15 is interposed which penetrates between the inner member 8 and the inner member 8 . In addition, the inner member 14 is attached to the base material 4, but like the inner member 8 of the mullion 6, this inner member 14 can also be omitted if there is a shaped steel material used for the curtain wall of an existing building. Good, Nao,
The outer member 13 has a flat plate shape, and the inner member 14 has a U-shaped cross section.

Then, a sealing material 16. is applied between the outer part 7.13 and the inner member 8. By holding the edge 20 of the wall material 19 through the adhesive 17, spacer 18, etc., and performing the above series of steps on each floor, a new outer wall can be easily formed. Although only the wall material 19 was used in the illustrated example,
If there is a window opening, glass may be provided there as a window material.

Furthermore, in the illustrated example, a horizontal drainage channel 21 is formed in the upper part of the passage member 15 in the horizontal branch 11, and the mullion 6
A vertical drainage channel 22 communicating with the drainage channel 21 is formed inside the outer member 7 of the frame 7 to ensure that rainwater is drained even if poor construction or deterioration of the seal oil 16 occurs at any position on the rectangular frame 12. 1. To enable discharge to the outside on each floor. ing. In addition, 23 is a communication hole for both drainage channels 21 and 22, 24 is a drainage hole, and 25
is the packing material for prevention.

As explained above, according to the present invention, the structure is as follows: (1) attaching a base material to the exterior wall of an existing building; or (1) removing the exterior wall of an existing building; [1] Vibe-shaped mullions are provided vertically and continuously at predetermined intervals on the outer surface of the existing building through the above base material, and horizontal branches are combined with the mullions to form a rectangular frame]- Window material inside this rectangular frame.

Since we decided to form a new exterior wall by retaining the wall materials, etc., we can eliminate the traditional effort of repainting the entire exterior wall surface of an old existing building or replacing the entire tile. It is possible to reliably form a new external wall, which is advantageous in terms of construction period and cost, and it also has the effect of improving the external appearance and also improving the design.

Claims (1)

[Claims] The base material can be attached to the outer wall of the existing building while leaving it as it is, or the outer wall of the existing building is removed to expose the existing base material, and the base material is attached to the outer surface of the existing building at predetermined intervals in the vertical direction through the base material. A vibrator-shaped mullion is provided in succession, and a rectangular frame is formed by combining this mullion with horizontal movement. Inside this rectangular frame r (window materials, wall materials, etc. are held to form a new outer wall. A method for renovating the exterior walls of existing buildings.
