Traditionally, the mainstream insulation method for building exterior walls has been the internal insulation method, in which a heat insulator is attached to the inside of the exterior wall. There are many problems such as cracks and damage caused by thermal stress and frost damage, reduced insulation effectiveness due to heat-cold bridges, and internal condensation, so in recent years an external insulation method has been developed and used in which the insulation is attached to the outside of the external wall. I'm getting old.

いる。 This type of external insulation method uses 6 as an exterior material.
Currently, a construction method that uses glass fiber reinforced cement plates, metal plates, etc. with a thickness of ~13 mm and an organic heat insulating material such as expanded polystyrene as a heat insulating material is generally used.

However, although this type of external insulation method has been recognized to have advantages such as no internal condensation and the ability to renovate the insulation while the building is in use, various conventional external insulation methods such as the above method None of the construction methods necessarily satisfy general performance, and there is a need for a review in particular from the aspect of fire prevention performance.

In order to achieve such an object, in the present invention, an exterior panel is formed by combining a water-repellent calcium silicate board exterior material and a phenol foam insulation material, and this exterior panel is attached to the exterior wall surface of a structural frame of a building exterior wall. It is fixed in place through mortar that is applied in advance to form a frame at the boundary between adjacent exterior panels, and a sealed space layer is formed between each panel and the exterior wall surface of the structural frame for each exterior panel. I made it.

A calcium silicate plate is subjected to water-repellent treatment using, for example, a predetermined primer, and a phenol foam heat insulating material is bonded thereto to form an exterior panel. and,
If the structural frame of the building exterior is a steel frame structure, the above-mentioned exterior panel is screwed to the outer wall surface, and if the structural frame is reinforced concrete, mortar is locally applied to the outer wall surface and the exterior panel is attached. It is then fixed to the structural frame using the specified metal anchor bolts. At this time, the metal anchor bolts used are small in diameter and make point contact, so the possibility of hot-cold bridges is extremely small and a high degree of heat insulation and fire resistance can be obtained. The closed space formed by the mortar prevents internal condensation.

FIG.
In the figure, the exterior panel 1 is formed as a whole in a square shape of, for example, 900 mm square, and is formed of a heat insulating material 2 made of a phenol foam board and an exterior material 3 made of a calcium silicate board. When manufacturing this exterior panel 1, for example, the exterior material 3 with a thickness of about 25 mm is treated with a water repellent treatment using, for example, a predetermined primer to prevent water absorption, and this exterior material 3 and, for example,
Attach the heat insulating material 2 with a thickness of about 25 mm using adhesive 4.

It is applied to each exterior panel 1 to form a sealed air layer, and is applied to the boundary between adjacent exterior panels 1 so as to form a frame shape. Then, before this mortar 6 hardens, the exterior panel 1 is laid and pasted, and a drill is inserted through the bolt hole 1a previously drilled in the exterior panel 1 to drill a bolt hole 5a in the structural frame 5. A metal anchor bolt 7 is driven into the bolt hole 1a to firmly fix the exterior panel 1 and the structural frame 5, and the counterbore hole 1b into which the head of the metal anchor bolt 7 is inserted is coated with a predetermined primer to make it water repellent. After the treatment, a heat-resistant coating treatment is performed, and putty 8 is filled on top of the heat-resistant coating treatment to give a smooth finish.

Afterwards, apply sealant 11.

くてハンドリングも良好である。 In the external insulation method carried out as described above, the calcium silicate board used as the exterior material 3 has extremely excellent heat resistance and heat insulation properties, so there is no need to worry about fire prevention, and it also serves as a heat insulator. fulfill Moreover, since the phenol foam used as the heat insulating material 2 is covered with the exterior material 3, it can fully exhibit its heat insulating performance. Furthermore, the exterior panel 1 itself is extremely lightweight and easy to install, and since the exterior plate 3 has been treated to be water repellent, its strength is improved, there are few defects, and handling is also good.

できる。 In addition, since a sealed air layer surrounded by mortar 6 is formed for each exterior panel 1, there is no risk of internal condensation, and therefore condensed water can enter the interior from the back of the panel and freeze or melt. It is possible to prevent peeling, damage, etc. between panel layers without repeating the process.

However, by using a method of fixing this exterior panel to the exterior surface of the structural frame of the building's exterior wall, the phenol foam insulation material, which has excellent heat insulation properties, is covered with the calcium silicate plate exterior material, which has excellent fire resistance. The insulation and fire resistance of the entire exterior panel are greatly improved. Furthermore, since the exterior panel is lightweight, it is easy to install, reducing the cost of materials such as mounting bolts, and shortening the construction period. Furthermore, by applying water-repellent treatment to the exterior material, its strength and durability are improved, and since a sealed space is formed with mortar, there is no risk of condensation, and there is no possibility of peeling or damage between panel layers. can be prevented,
Durability can be further improved.
