A new window is installed on the new outer wall so that it looks like a bay window,
Japanese Patent Application Laid-Open No. 4-42513 discloses that the space used in the room is substantially expanded.
It is expected that this use space will be used for placing flower pots and small ornaments, or for installing curtain rails, and it is premised that the space between the old and new outer walls is made as small as possible.

Further, even if the outer wall is renovated at high cost by the above-mentioned construction method, there is no particular contribution to the function of the building itself, and the heat insulating effect of the outer wall is slightly improved,
It was only enough to form a bay window. The new use of the new outer wall is not considered.

In addition, the names such as intelligent buildings have come to be used, and in recent buildings, various equipment such as electric equipment, water supply / drainage hygiene equipment, communication equipment, and gas equipment have come to be used in various ways. There is. In an old building, when installing or adding these equipments, it is not possible to secure a space such as a duct for piping and wiring, and there is a building that cannot cope with intelligentization.

FIG. 3 is an explanatory view of an embodiment of a mounting structure, FIG. 3 is a layout view of piping, and FIG. 4 is a side sectional view of a building. In the figure, 1 is a new panel, 2 is an old outer wall, 3 is a window,
4 is a horizontal base material, 5 is a vertical base material, 6 is an anchor bolt, 7
Is a base fixing bracket, 8 is a connecting member, 9 is a panel fixing bracket, 10 is wiring, 11 is a floor line, 12,
12a, 12b and 12c are equipment, 13 is a building frame,
14 is the floor surface, 15 is the old head tree, and 16 is the new head tree.

As shown in FIG. 1, this building is a four-story building. The left side of the figure shows a state in which the new panel 1 is attached as a new outer wall, and the right side shows a state in which the new panel 1 is removed. The window 3 is provided on the old outer wall, and the window member of the old building is used as it is, or the window member of the old building is removed and a new window member is attached,
The window member is attached to the frame of the old building. However, the window member is not limited to this,
Further, a window member may be attached to the new outer wall side to form a double window, or the old window member may be removed and a new window may be provided only on the new outer wall side. A blind shutter may be attached to the new outer wall side or the old outer wall side.
To install the new panel, the horizontal base material 4 is fixed on the old outer wall 2, the connecting member (not shown) is attached to the horizontal base material 4, the vertical base material 5 is attached via the connecting member, and the new vertical base material 5 is attached. Install panel 1. In this embodiment, the horizontal base material 4 is provided so as to extend in the horizontal direction, but a part may be cut off. Also,
A vertical base material 5 is arranged in the vertical direction between the windows in the horizontal direction.

An embodiment of a mounting structure for a base material will be described with reference to FIG. 2A is a top view and FIG. 2B is a side view. The old outer wall 2 is hatched only in a part near the surface in order to make the drawing easy to see. An anchor bolt 6 is driven from the old outer wall 2 to the body to fix the base fixing bracket 7. The horizontal base material 4 is fixed to the base fixing bracket 7 by welding or bolting, and the connecting member 8 is fixed to the base fixing bracket 7 similarly by welding or bolting. Next, the vertical base material 5 is fixed to the connecting member 8 by welding, bolting or the like, and the base material is attached to the old outer wall 2. The new panel 1 is attached to the vertical base material 5 via the panel fixing bracket 9.

Although the base fixing bracket 7, the horizontal base material 4, the connecting member 8 and the vertical base material 5 constitute the mounting member, the structure of the mounting member may be arbitrary. Of course, the vertical base material 5 may be fixed to the base fixing bracket 7, and the horizontal base material 4 may be attached via the connecting member. As will be described later, when the space between the old outer wall 2 and the new outer wall 1 is increased to be used as a ventilation space or an installation space for piping, wiring, equipment, etc., the length of the connecting member 8 is lengthened. Therefore, an appropriate effective space can be secured.

In this embodiment, the space between the new panel 1 and the old outer wall 2 is selected as the length of the support member 8 so that ventilation is possible, and a ventilation space is secured. Further, a ventilation hole is provided below the new outer wall, and a ventilation hole is also provided above. Although the vent will be described later, a shieldable vent is used. The lower vent is a fixed or movable louver in the area A near the surface of the new outer wall in the area A, and the window 3 on the first floor in the area B. In the area C, a window frame provided with an air vent in the upper frame portion of the window 3 of the window 3 provided on the second floor is illustrated. As will be described later, the upper vent can be provided with a space between the old head and the new head and used as the vent.

The relationship between the building and solar radiation is that the temperature is high and the solar radiation is strong in summer. Since the temperature of the wall surface irradiated with sunlight has a large temperature rise, the heat taken in from the wall surface enters the room and the cooling effect is diminished. Therefore, it is advantageous from the viewpoint of energy saving to ventilate the space between the old outer wall and the new outer wall to prevent the heat taken in from the wall surface from entering the room. If the ground near the building is in an environment where the temperature rise is small and is lower than the temperature due to shrubs or grass, it is preferable to use the ventilation port as shown in the area A.
In an environment where the ground near the building is paved and radiant heat from it is large, the temperature is lower at a height higher than the ground. In such an environment, depending on the situation, air may be taken in from the first floor portion shown in the area B or the second floor portion shown in the area C,
The taken-in air flows upward as shown by the arrows, and escapes. Due to this air flow, the heat absorbed by the outer wall surface can be discharged upward, the temperature rise in the room can be suppressed, and significant energy saving can be realized.

In winter, the vents are blocked to prevent air flow. Significant energy savings can be realized because the outer wall cooling can be suppressed and the air layer can be used as an adiabatic space without absorbing the sunlight on the new outer wall surface and releasing the warmed air. Sound insulation characteristics are also improved.

When the air conditioner is not used in spring or autumn and there is a large change in air temperature, air conditioning may be desired. If each room or the like is provided with an individual air conditioner / heater, the operation control can be appropriately performed. However, even if there are individual air conditioners, power may not be supplied to the wires of the air conditioners except during the air conditioning period.
In such a case, even if the air conditioner is used,
Often there is no need for powerful air conditioning. At this time, without using the air conditioner and heater, control the vent,
Energy can be saved in the intermediate period between cooling and heating by ventilating the heat in the room or by shutting off the heat in the room.

Piping and wiring may be housed in this space. As shown in FIG. 3, the piping and wiring are arranged between the left and right sides and the upper and lower sides of the window 3. In FIG. 3, piping 10 for air conditioning is used.
However, the present invention is not limited to this. Gas pipes,

As the communication line, a connection line between each room in the building and the outside such as a telephone line, a coaxial cable, an optical wiring, and a control line can be arranged.

The pipes and wiring are connected to facility equipment arranged in a necessary room. FIG. 3 schematically illustrates the case where the piping is pulled in toward the ceiling side or the floor side.
The part shown by the dotted line is not connected to the piping shown in the upper part, but shows that different piping is performed. Therefore, the piping and wiring may be connected to the facility equipment alone or may be branched from the main line and connected. These pipes and wirings are usually connected to main equipments arranged in a control room, a machine room, etc., using equipments in each room as terminal equipments. Such a main facility device may be installed on an appropriate floor or may be installed on the rooftop.

In the above description, the space for ventilation between the old outer wall and the new panel is used to arrange the piping, wiring, equipment and the like, but ventilation is not performed. It is not always necessary, and piping, wiring, facility equipment or the like may be arranged without providing a vent hole described later.
