Description

Base panel, exterior wall decoration method and prefabricated curtain wall

technical field

The present invention relates to a base panel for building exterior walls and an exterior wall decoration method using the base panel. The present invention also relates to a precast concrete (hereinafter referred to as PC) curtain wall for the outer wall of a building.

Background technique

Generally, the method of installing exterior wall decoration materials such as ceramic tiles on the exterior wall of a building is to use a composite board or a calcium silicate board as a base for construction, and to paste a net on the base material as a reinforcing material. After the base mortar is applied thereon and allowed to harden, the adhesive mortar is applied thereon and the outer wall finishing material is bonded. However, a method is also known in which a heat insulating material is used as a base material, thereby performing exterior heat insulation work simultaneously with exterior wall decoration work. For example, Japanese Patent Application Laid-Open No. 2002-220886 proposes an external thermal insulation construction method for pasting ceramic tiles. After the thermal insulating material is pasted on the outer surface of the main body constituting the outer wall of the building, mortar mixed with short fibers is applied to the thermal insulating material. On the surface, the net is superimposed on it, and then the second layer of mortar is applied and fluffed. After the mortar is cured, the net is fixed to the main body with anchor bolts, and the base mortar is applied on the second layer of mortar. After curing, apply mortar and tiles.

However, when installing exterior wall decoration materials such as ceramic tiles with these conventional methods, it is necessary to perform many operations such as posting the net on site, coating the base mortar and curing it, and then coating the adhesive mortar on it. Problems that require a lot of labor, and problems that require a long construction period.

In JP-A-11-62168, a structure is proposed in which a long-pile cloth is installed on the outside of the pasting surface side of the base forming plate such as a calcium silicate plate as the finishing material, and it is used as an adhesive. Base material for finishing materials such as tiles. Using this base material, after applying mortar to the long-pile fabric, and then pasting finishing materials such as tiles, the long-pile yarn part of the long-pile fabric can be applied to the mortar to produce the effect of ground anchors, which can improve The bonding strength of the finishing material, therefore, has the advantage of making the posting operation of the finishing material simple and convenient. However, when the mortar is applied to the long-pile fabric on this base material, the long-pile yarn portion will be pressed and looped, and there is a problem that the ground anchor effect cannot be fully exhibited.

In No. 2002-339469, a PC curtain wall is proposed, which is based on the requirement that the exterior wall decoration or external heat insulation can be easily carried out in the construction method of the PC curtain wall. PC curtain wall with thermal insulation structure. The PC curtain wall proposed in this gazette is such a structure, that is, it is that the exterior decoration material is installed on the outer wall surface of the panel structure; It is a structure in which the mesh and the heat insulating board are bonded to prevent the scattering of the exterior decoration material, and the above exterior decoration material is held on the panel structure by the locking member. However, in terms of fixing the exterior decoration material on the panel structure with the locking parts, the PC curtain wall is limited to the boards whose exterior decoration materials are quite wide and thick (such as natural stone slabs or artificial slabs with a thickness of 15-30mm). Slate, etc.), there is a problem that it is not suitable for posting multiple tiles.
