Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal aluminum exterior panel suitable for an external heat insulation method and a method for constructing a horizontal aluminum exterior panel.

[0002]

2. Description of the Related Art Heretofore, construction of exterior materials of a building with external insulation has been performed by the following method. In heat insulation of buildings such as reinforced concrete construction, the outer heat insulation method is extremely rarely applied, and most of the heat insulation methods do not use heat insulation material or the inner heat insulation method uses foam heat insulation material inside the building. In addition, energy saving of heating and cooling energy, indoor surface dew condensation, and internal dew condensation are becoming problems, and an external heat insulation method is being adopted as a countermeasure. 1. In the external heat insulation method, a foam-based heat insulating material is used outside the concrete body, and a mortar finish is directly applied to the outside of the concrete body, and then a coating process or an exterior material such as a tile is attached. 2. When fiber-based heat insulator (glass wool, rock wool) is used as the heat insulation material of the external heat insulation method, the wall structure of concrete skeleton, heat insulation, exterior material support hardware, exterior material (metal-sided, ceramic-sided, etc.) Some have a ventilation layer that allows moisture-permeable water vapor from the room to escape, while others do not. In a method with a ventilation layer, the intake of outside air generally enters through the intake hole drained at the bottom of the building, and the air containing water vapor in the ventilation layer discharges the air through the exhaust hole at the top of the building. It is discharged from a discharge port such as a cell hood attached to the top wall.

[0003]

The above-mentioned prior art has the following problems. 1. In winter or the like, water vapor generated indoors moves through the concrete and the heat insulating material from the indoor side and moves outdoors. For example, when the temperature and humidity are 22 ° C. 50% indoor and -5 ° C. 50% outdoor, the indoor partial pressure of steam is 9.9 mmHg,
When the water vapor partial pressure on the outdoor side is 1.5 mmHg, a pressure difference is generated from the indoor side to the outdoor side with a water vapor partial pressure difference of 8.4 mmHg, and the water vapor moves. Even in the external insulation method, if the treatment of water vapor that permeates the concrete frame from the room is not sufficiently considered, dew forms inside the outer wall where the temperature is low, peeling of the exterior material due to frost damage in winter and retaining water in the insulation material enough Insulation performance cannot be maintained. For this reason, a method of providing a ventilation layer between the heat insulating material and the exterior material and discharging water vapor to the outside has been adopted.However, when a foamed heat insulating material is used as the heat insulating material, there is a problem in fire resistance, and the ventilation layer is formed. This is not provided and the above problem occurs. 2. Also, in a building that uses a fiber-based heat insulating material as a heat insulating material and has a ventilation layer, the method of introducing outside air from the drainage at the bottom of the building and discharging air containing water vapor from the top cap and cell hood is There is no problem if the height of the building is low.However, in the middle to high-rise buildings, the air moving in the ventilation layer will contain more water vapor as going to the top, and the water vapor emission conditions will go up to the top of the building. Not only does the air quality deteriorate, but when the temperature of the outside air is low, there is a risk of dew condensation on the inner surface of the exterior material or the surface of the heat insulating material. 3. In the case of commercial buildings, etc., windows on each floor are often installed side by side with the building, and in this case, the ventilation layer is divided for each floor, and the outside air entering from the bottom of the building reaches the top. Since the structure cannot be pulled out of the structure, the function of the ventilation layer cannot be fulfilled.

[0004] The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. 1. The exterior panel of the present invention is a long aluminum extruded panel to be stretched in the lateral direction. The lower part of the vertical section is a box-shaped part, and the lower surface has ventilation and water holes for the outside air, and the upper part of the box-shaped part has ventilation holes for the ventilation layer to the lower outside air. It is opened in a state shifted laterally from the ventilation / water hole. The lower part of the box-shaped part is formed with a ridge that can be fixed by being inserted into the upper part of the panel attached from below. The upper part is provided with a small wall for attaching to the exterior material attaching material from the building side with a tapping screw or the like. Further, a connection receiving groove into which the projecting ridge of the panel is attached is formed. 2. In a state where the exterior panel of the present invention is continuously assembled above the lower part of the building, outside air entering from the groove portion of the joint portion of the panel communicates with the ventilating portion opened below the box-shaped portion. It passes through the inside of the box-shaped part from the water hole, and below the upper back of the box-shaped part, the ventilation and water hole sends air to the ventilation layer on the back of the exterior panel from the ventilation hole that has been opened laterally shifted. . Also, when rainwater is blown by wind or the like, the rainwater once enters the box-shaped portion through the ventilation / water passage hole below the box-shaped portion, but the cross-sectional area of the box-shaped portion is larger than the entered ventilation / water passage hole. Therefore, the velocity of the air passing through the inside of the box-shaped part drops, and the water and the air are separated, thereby preventing the rainwater from being blown into the ventilation layer 8. In order to prevent rainwater from being blown, it is possible to change the cross-sectional shape of the baffle plate or the box-shaped portion into the box-shaped portion so as to provide resistance. 3. The ventilation / water holes and ventilation holes opened in the panel due to the direction of the wind blowing outside the building, the outside air temperature, etc., pass through the inside of the box from the ventilation holes opened above the box-shaped part of the panel from the ventilation layer, and It also functions as a passage for discharging air to the outside of the ventilation and water holes formed below the shape. 4. By using the exterior panel of the present invention, a building in which outside air entering the ventilation layer from the lower part of the building cannot be discharged from the top of the building while rising through the ventilation layer (a building provided with windows and the like continuously) ), And by using the exterior panel of the present invention in a building having a medium height, a high-rise building, and a long distance between the ventilation layers, the panel can be provided regardless of the air intake or exhaust port to the ventilation layer or the distance. The water vapor inside the wall body can be released to the outside by the ventilation / water passage hole and the ventilation hole opened in the wall.
