Description

  The present invention relates to a base panel used for an outer wall of a building and an outer wall makeup method using the base panel. The present invention also relates to a PC curtain wall used for an outer wall of a building.

  As a method of attaching an outer wall decorative material such as tiles to the outer wall of a building and generally making an outer wall, a plywood or a calc board is used as a base, and a net is attached to the base as a reinforcing material. The base mortar was applied and cured, and then the adhesive mortar was applied thereon to adhere the outer wall decorative material. In addition, there is also known a method of performing an outer heat insulating work simultaneously with an outer wall decorative work by using a heat insulating material as a base material. For example, in Japanese Patent Application Laid-Open No. 2002-220886, a heat insulating material is pasted on the outer surface of a housing that forms the outer wall of a building, and then a mortar containing short fibers is applied to the surface of the heat insulating material with a trowel. Next, apply the mortar of the second layer with a trowel and brush it, and after the mortar has hardened, fix the net to the housing with anchor bolts, apply the base mortar on the mortar of the second layer, and cure After that, a tiled outer insulation method in which a mortar is applied and a tile is attached has been proposed.

  However, these conventional methods require many operations such as attaching a net on site, applying and curing a base mortar, and further applying an adhesive mortar thereon when attaching an outer wall decorative material such as a tile. There is a problem that a great deal of labor is required and the construction period is long.

  Japanese Patent Application Laid-Open No. 11-62168 has a structure in which a napped fabric is attached to the outer side which is the surface to which a finishing material of a base molding plate such as a calcium plate is attached as a base material to which a finishing material such as a tile is bonded. Proposed. In this base material, by applying mortar on the napped fabric and attaching a finishing material such as tiles, the napped yarn part of the napped fabric is applied in the mortar to serve as an anchor and bind the finished material. It has the advantage that the strength can be increased and therefore the work of pasting the finish can be simplified. However, with this base material, when the mortar is applied on the napped fabric, the napped yarn portion may be crushed, and the anchor effect may not be sufficiently exhibited.

Even in the construction method using a PC curtain wall, it is required to easily perform exterior wall decoration and heat insulation, and a PC curtain wall having an exterior wall decorative surface and an exterior heat insulation structure is proposed in Japanese Patent Laid-Open No. 2002-339469. Has been. The PC curtain wall proposed in this publication has a structure in which an exterior material is attached to the outer wall surface of the panel structure, and the exterior material adhered to the back surface of the exterior material between the exterior material and the panel structure. A scattering prevention net and a heat insulating plate are arranged, and the exterior material is held on the panel structure by a locking tool. However, this PC curtain wall is limited to a plate material that is considerably wide and thick (for example, a natural stone plate or an artificial stone plate having a plate thickness of 15 to 30 mm) because the exterior material is fixed to the panel structure by a locking tool. Therefore, there is a problem that it cannot be applied when a large number of tiles are pasted.

  An object of the present invention is to provide a base panel capable of shortening the work period by simplifying the outer wall decorative process such as attaching an outer wall decorative material such as a tile to the outer wall of a building.

  Moreover, this invention makes it a subject to provide the base panel which can form an outer heat insulation structure or an outer-layer heat insulation structure while being able to simplify the outer wall decoration process with respect to the outer wall of a building, and to shorten a construction period.

  Moreover, this invention makes it a subject to provide the outer wall makeup | decoration method which makes it possible to perform the outer wall makeup | decoration of a building in a short construction period.

  Further, the present invention provides a heat-insulating PC curtain wall provided with an outer wall decorative material such as tiles and a heat insulating material layer in advance so that the outer wall of the outer heat insulating structure subjected to the outer wall decoration can be formed by a simple process. Let it be an issue.

The mixing ratio of polymer to cement is preferably 20 to 60 parts by weight of polymer with respect to 100 parts by weight of cement. When the ratio of the polymer is reduced, the fluidity when impregnating the polymer cement liquid into the nonwoven fabric sheet becomes insufficient and impregnation becomes difficult, and the nonwoven fabric sheet after impregnating the polymer cement becomes too hard and winding is difficult. It becomes. On the other hand, the higher the polymer ratio, the higher the cost. For this reason, it is preferable to determine as described above. The amount of impregnation per unit area of the polymer cement on the nonwoven fabric sheet surface is preferably 500 to 1200 g / m ² . When the amount of impregnation decreases, the effect of impregnating the polymer cement decreases, while when the amount increases, the cost increases and the sheet after impregnating the polymer cement becomes too hard and winding becomes difficult. For this reason, it is preferable to determine as described above.

The nonwoven fabric sheet can be impregnated with polymer cement on one side, and can be joined to the opposite side so as to be integrated with a ceramic board layer or a heat insulating material layer, and has an alkali resistance. However, in particular, a material having a large number of voids on both surfaces or a large number of three-dimensionally arranged fibers on both surfaces (between fibers) so that a good anchoring effect can be exerted on the material bonded to both surfaces. Those having fibers arranged in such a form that many voids are formed are preferred. As a suitable example of a nonwoven fabric sheet, it is made by needling an alkali resistant fiber (which may be either a short fiber or a long fiber) to a base material sheet made of an alkali resistant material, and per area thereof. Of 80 to 200 g / m ² can be mentioned. The base sheet used here is arbitrary as long as it has a strength capable of supporting the fibers to be needled, and a nonwoven fabric, a spunbond, a woven fabric, paper, a sheet, a film, and the like can be used.

For this reason, the heat insulating material layer is composed of a foam heat insulating material of phenol foam, styrene foam, or urethane foam. It is preferable. This heat insulating material layer may be formed by pre-molding it into a plate shape by bonding it to a nonwoven fabric sheet or ceramic board layer using an adhesive, or foam insulation on the nonwoven sheet or ceramic board layer. You may form by pouring the raw material liquid for material manufacture and direct foaming. The thickness of the heat insulating material layer may be appropriately determined according to required heat insulating properties, and is usually selected to be about 15 to 60 mm.

  The ceramic board layer used in the base panel of the present invention is provided with rigidity, strength, flatness, etc. suitable for holding an outer wall decorative material such as tiles. A calcium silicate board, a calcium silicate board, a slag gypsum board, a magnesium carbonate board, a magnesium cement board, etc. can be mentioned, As a more suitable example, magnesium oxide and silica sand are the main ingredients, and a glass fiber nonwoven fabric or glass fiber is used on both sides. A structure in which a net is embedded can be mentioned. This structure has the advantages of high strength and rigidity, and excellent dimensional stability and heat resistance. The ceramic board layer may be formed by pre-molding it into a non-woven sheet using an adhesive, and by laying and curing the ceramic board production raw material on the non-woven sheet. May be formed. The thickness of the ceramic board layer may be appropriately determined according to required strength, rigidity, etc., and is usually selected to be about 3 to 20 mm.

A laminated body 1A having a structure in which the system board layers 4 are integrally laminated is manufactured. Thereafter, the laminated body 1A is set in a mold frame with the ceramic board layer 4 side facing upward, and the foam heat insulating material manufacturing raw material is poured and foam-cured thereon to be molded into a desired shape. Thus, the base panel 10 shown in FIG. 3D can be manufactured.

  Since this base panel 10 is provided with the foam heat insulating material layer 11, it can be used for both the outer heat insulating method and the outer heat insulating method. Hereinafter, the usage method of the base panel in each construction method will be described. FIG. 4 shows an example in which the base panel 10 is used for the outer heat insulation method. First, the base panel 10 is attached to the housing 5 forming the outer wall of a building such as a building, using the anchor 6a such as a plastic anchor and the fastener bolt 6b with the nonwoven fabric sheet 3 side facing outward.

Thus, the outer heat insulating process and the outer wall decorative process are completed. As described above, the use of the base panel 10 eliminates the need for the heat insulating material attaching process, the netting work, and the base mortar application, which are conventionally required, and can shorten the process. Further, in the obtained wall surface, the adhesive mortar 7 is applied to the surface of the nonwoven fabric sheet impregnated with the polymer cement and the outer wall decorative material 8 is pasted. Therefore, due to the excellent adhesion between the polymer cement and the adhesive mortar, and Due to the anchor effect of the three-dimensionally existing fibers 3b (see FIG. 3) on the surface of the nonwoven fabric sheet 3, the adhesive mortar 7 is very firmly adhered to the nonwoven fabric sheet 3, and the outer wall decorative material 8 is used over a long period of time. And the adhesive mortar 7 does not peel off.

  2, 4, and 5, all of them apply adhesive mortar to the surface of the base panels 1 and 10 and attach the outer wall decorative material 8. However, the present invention can be changed as appropriate. For example, a finish mortar may be applied to the surfaces of the base panels 1 and 10 to make the outer wall makeup, or the outer wall makeup by spray coating may be performed. Even in these cases, since finishing mortar application or spray coating is performed on the polymer cement-impregnated non-woven fabric sheet, the adhesion stability of the decorative surface is excellent, and the surface does not peel or fall off over a long period of time.

  Moreover, in the base panel 10 shown in FIG.3 (d), the ceramics board layer 4 is arrange | positioned between the nonwoven fabric sheet 3 and the foam heat insulating material layer 11. FIG.
