BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating outer wall panel and a heat insulating outer wall structure.
[0002]
[Prior art and problems]
2. Description of the Related Art An inner heat insulation type outer wall panel in which a panel frame is attached to the back surface portion of an outer wall material and a fiber-based heat insulating material such as glass wool is packed inside the panel frame is well known.
[0003]
However, this outer wall panel has disadvantages such as that internal condensation tends to occur, the room temperature tends to fluctuate due to a heat bridge, and the joints between the panels must be wet-coked.
[0004]
In such a background, the present invention is less likely to cause internal dew condensation, can reduce heat bridges to suppress room temperature fluctuation, can be sealed between panels with a dry joint material, and has many advantages. It is an object to provide a heat insulating outer wall panel and a heat insulating outer wall structure.
[0005]
[Means for Solving the Problems]
Said subject is solved by the heat insulation outer wall panel characterized by the plate-shaped outer heat insulating material being piled up on the outdoor side of a panel frame, and the outer wall material being provided in the outer side.
[0006]
This heat insulating outer wall panel is configured as a so-called outer heat insulating outer wall panel in which a plate-like outer heat insulating material is stacked on the outdoor side of the panel frame, and therefore, internal condensation is unlikely to occur. In addition, it is possible to insulate between the outer wall panels with an outer heat insulating material, thereby preventing a heat bridge and suppressing a change in room temperature to be small. In addition, the depth of the joint between the adjacent outer wall panels is greatly secured by the outer heat insulating material, and the outer wall panels can be sealed with the dry joint material, so that the workability of the waterproof construction of the joint can be improved. It becomes.
[0007]
Not only that, the outer wall panel is provided with the outer heat insulating material so as to overlap the panel frame of the outer wall panel. Therefore, the outer heat insulating material can be reinforced with the panel frame. The material can be eliminated, and the outer wall structure can be simplified. In other words, when the outer wall panel and the outer heat insulating panel are configured as separate panels, the outer heat insulating material requires a special frame material to reinforce this, but the panel structure in which the outer heat insulating material is pre-installed in the outer wall panel By doing so, a frame material dedicated to the outer heat insulating material can be eliminated, and the outer wall structure can be made a simple structure.
[0008]
As an external heat insulating material, for example, a foamed resin such as polypropylene foam, polystyrene foam, and foamed polyurethane, or an organic material such as phenol or isocyanurate, a halogen blended with these, or a fireproof performance is improved. An inorganic foam material having excellent performance is used. In addition, by using a water-resistant material such as polypropylene foam as the outer heat insulating material, it is possible to prevent rainwater and the like from entering the panel with the outer heat insulating material itself.
[0009]
When the inner heat insulating material is provided inside the panel frame, the inner heat insulating material and the outer heat insulating material can not only improve the heat insulating performance but also wet the inner heat insulating material with internal condensation. Can be prevented. Moreover, by using the inner heat insulating material, the thickness dimension of the outer heat insulating material can be reduced, and the protrusion of the outer heat insulating material to the outside of the building can be suppressed to be small. In addition, the start-up of indoor air conditioning can be accelerated. As the inner heat insulating material, a fiber heat insulating material such as glass wool or rock wool may be used, or a foamed resin such as urethane foam may be used.
[0010]
In the case where a recess for forming a ventilation layer is formed in the outer surface portion of the outer heat insulating material, it is possible to form a gas permeable layer between the outer heat insulating material and the outer wall material. Not only that, the inner surface side of the outer heat insulating material is supported and reinforced by the panel frame, so there is no need to provide a reinforcing frame on the outer surface side of the outer heat insulating material. Therefore, an outer wall panel having a ventilation layer between the outer heat insulating material and the outer wall material can be realized with a simple structure. Moreover, the outer wall panel can be easily manufactured by manufacturing the outer wall panel using the outer heat insulating material in which the recess is formed in advance.
[0011]
When the outer wall material is attached to the outer heat insulating material, it is not necessary to screw a mounting bracket such as a screw deeply into the panel frame, and the outer wall material can be easily attached. In this case, as the outer heat insulating material, a material having rigidity that can serve as a base for the outer wall material may be used.
[0012]
If the outer heat insulating material is made of foamed resin and a heat-resistant spacer is embedded inside, and the outer wall material is connected to the panel frame through this spacer, the outer heat insulating material will burn out due to a fire, etc. However, it is possible to prevent the outer wall material from falling off.
[0013]
The above-mentioned heat insulation outer wall panels are attached to both sides of the pillars of the building frame so that the pillars are sandwiched from both sides by the panel frame, and the outer heat insulating materials of each outer wall panel protrude to the front side of the pillars and face each other with a predetermined interval, In the case of the heat insulating outer wall structure in which the dry joint material is fitted between the facing surfaces, the joint can be sealed with the dry joint material in this way, and the joint can be efficiently constructed.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0015]
In the heat insulating outer wall panel 1 of the embodiment shown in FIGS. 1 and 2, 2 is a panel frame, 3 is an outer heat insulating material, 4 is an outer wall surface material as an outer wall material, and 5 is an inner heat insulating material.
[0016]
The panel frame 2 is formed by assembling upper, lower, left and right steel channel shapes in a square ring shape with the opening side facing inward, and an inner heat insulating material 5 is provided inside the panel frame 2. The inner heat insulating material 5 is made of, for example, glass wool.
[0017]
And the plate-shaped outer heat insulating material 3 is piled up and attached to the outdoor side of this panel frame 2. FIG. The outer heat insulating material 3 is made of, for example, a foamed resin molded product, such as polypropylene foam, which is excellent in all of heat insulating properties, rigidity, water stop / waterproof properties. Thus, by setting it as the structure which attaches the outer heat insulating material 3 so that it may overlap with the panel frame 2 of the outer wall panel 1, the outer heat insulating material 3 can be reinforced with this panel frame 2, and it is exclusive from the outer heat insulating material 3. Thus, the outer wall structure can be simplified as shown in FIG.
[0018]
As shown in FIG. 1 (a), the outer heat insulating material 3 is provided such that its left and right side portions protrude laterally from the panel frame 2, and this protruding portion is shown in FIG. 3 and FIG. As shown, it projects over the front side of the pillar 6 of the building frame.
[0019]
Further, on the side surface of the outer heat insulating material 3, for example, as shown in the drawing surface, irregularities such as recesses 7 and 7 extending in the vertical direction are formed. The unevenness is for engaging the dry joint material and is formed directly on the side surface portion of the outer heat insulating material 3.
[0020]
Further, a plurality of vertically extending recesses 8 are arranged in the lateral direction on the outer surface portion of the outer heat insulating material 3, and the outer wall surface material 4 is attached so as to be along the outer surface portion of the outer heat insulating material 3. In the state, a ventilation layer 9 is formed between the outer heat insulating material 3 and the outer wall surface material 4. The recess 8 for forming the ventilation portion is formed directly in the outer heat insulating material 3, and may be formed by, for example, simultaneous molding when the outer heat insulating material 3 is formed.
[0021]
An outer wall surface material 4 is provided on the outer surface side of the outer heat insulating material 3. The outer wall surface material 4 is attached as follows. In other words, a cylindrical or ring-shaped heat-resistant spacer 10 made of metal or resin is embedded in the outer heat insulating material 3, and a mounting bracket 11 such as a screw is passed through the spacer 10. The outer wall surface material 4 and the panel frame 2 can be maintained in the proper mounting state by the mounting bracket 11 via the spacer 10 without the outer heat insulating material 3. Has been made. Thereby, even if the outer heat insulating material 3 should be burned down by a fire, it can prevent that the outer wall surface material 4 falls off from a building.
[0022]
As shown in FIGS. 3 and 4, the outer wall panel 1 is attached to both sides of the pillar 6 of the building frame so that the pillar 6 is sandwiched from both sides by the panel frames 2 and 2. As a result, as shown in FIG. 4B, the outer heat insulating materials 3 and 3 of the respective outer wall panels 1 and 1 project to the front side of the column 6 and face each other with a predetermined joint width interval. Heat bridge is suppressed by the outer heat insulating materials 3 and 3 projecting to the front side of the column 6. Then, a dry joint material 12 is fitted between the opposing surfaces, and the space between the outer wall panels 1 and 1 is sealed. As the dry joint material 12, it is preferable to use an elastic rubber material that follows the joint width variation. Thus, by setting it as the outer wall panel 1 incorporating the outer heat insulating material 3, the depth dimension of the joint 13 can be enlarged to some extent, and the dry joint material 12 can be used for sealing the joint 13. Thus, the joint construction can be performed efficiently. In particular, the dry joint material 12 can be firmly held in the joint 13 by the engaging action of the concave and convex portions formed on the side surface of the outer heat insulating material 3 and the like. Since the concave and convex portions due to the concave stripes 7 and the like may be formed on the side surface of the foamed resin outer heat insulating material 3, it can be easily formed.
[0023]
The outer wall panel 1 of the embodiment shown in FIG. 5 and FIG. 6 is composed of a tiled outer wall panel, and a tile is attached to a siding with an adhesive or a screw as an outer wall material 4, and a plurality of these outer wall materials 4. The outer surface of the material 3 is attached to the outer heat insulating material 3 by siding fixing hardware 15. In this case, the outer heat insulating material 3 is firmly held by the outer heat insulating material 3 by using a foamed resin having high rigidity as a base such as polypropylene foam and excellent in water-stopping property. In addition, the outer heat insulating material 3 can prevent intrusion of rainwater or the like. A recess 16 for attaching the siding fixture 15 may be formed on the outer surface of the outer heat insulating material 3. By attaching the siding fixed hardware 15 so as to protrude into the recess 16, the outer wall material 4 and the outer heat insulating material 3 can be brought into a close state. Although not shown, the outer wall material 4 is formed by vertically extending the recesses 9 for forming the ventilation layer somewhat deeper than the recesses 16 for the siding fixing hardware 15 on the outer surface of the outer heat insulating material 3. It is possible to smoothly flow rainwater and the like that has entered the back side of the water.
[0024]
Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, the plate-like outer heat insulating material may be a single piece, or may be configured by combining a plurality of heat insulating materials in the vertical direction and / or the horizontal direction. In the embodiment shown in FIGS. 5 and 6, the siding fixed hardware 15 may be attached to the panel frame 2 by screws or the like via the outer heat insulating material 3.
[0025]
