Description

  The present invention relates to a technique relating to an external heat insulation method for an outer wall and a roof of a wooden or lightweight steel-framed building or the like and an effective use of solar energy.

  It is a well-known fact that the outer insulation method is much more efficient than the inner insulation method when considering the heat storage properties of walls and huts in the insulation method of the outer walls and roof of buildings. . However, generally used thermal insulation materials have drawbacks such as weather resistance, aesthetics, and structural strength. Cannot be supported, and can only be obscured with other materials or used as an internal filler.

  Conventional external heat insulation methods can be classified into approximately four types. The first is to provide a base set for external finishing on the outside of a wooden frame or the like, and to fill a gap therebetween with a heat insulating material. Secondly, a plate-shaped heat insulating material is disposed outside a wooden frame or the like, and the heat insulating material is sandwiched between the plate-shaped heat insulating materials to form a foundation. Third, a heat insulating panel in which a finishing material and a heat insulating material are combined is fixed to a wooden frame or the like. The fourth is a method of directly performing an external finish on the outside of the heat insulating material by a method such as spraying or bonding.

However, in the first method, it is difficult to provide an effective heat-insulating layer between the external finish and the wooden frame, etc., and a heat bridge is generated to impair the heat-insulating effect and the workability is poor. In the second method, the heat bridge is suppressed, but since the base material is assembled by sandwiching the heat insulating material, a variety of external finishes, particularly nails and screws, which are fixing members for supporting a heavy finish material, are used. There is a problem with the strength of the steel and the workability is poor. The third method is that an insulating material is sandwiched between a wooden frame or the like and a finishing material, such as an industrialized house, and an integrated panel is manufactured in advance at a factory, or a product obtained by bonding the insulating material and the finishing material to a wooden structure at the site. There is a method of fixing to a frame or the like, but there is a drawback that the finishing material is limited. The fourth method requires a certain structural strength of the heat insulating material, and can only cope with a limited external finishing material.

The structural support (A) has the following configuration. The size and spacing of the structural support (A) shall be determined in consideration of the weight of the external finishing material, etc., and the through holes (3) for using nails and screws for fixing and the heads of the nails and screws will be used. It has a recess (4) for sinking, the length of which is the same as the thickness of the heat-insulating layer (C) and can directly reach the wooden frame (D). Securely fixed inside by integral molding or bonding.

  A plate-like external finish that enables use as a heat-collecting layer in summer to reduce energy loss due to temperature rise on the external finish surface due to solar radiation, and in winter to serve as a heat-collecting layer for passive solar systems using solar energy during daytime The base (B) has the following configuration. On the outer side of the thin plate (1), a rib-like projection (2) also serving as a force bone for fixing an external finishing material with a nail or a screw is provided, and a wooden frame or the like is provided at the position of the rib-like projection (2) ( D) An integrated ribbed version with a structural support (A) arranged so that it can be directly fixed to D). The rib-shaped projections are provided in parallel with the short side of the plate in accordance with the spacing of the base such as a wooden frame or the spacing of the nails or screws of the external finishing material, so that the convection of warm air between the external finishing material is achieved. To create a space (E).

  The length of the rib-shaped projections (2) is shorter than the working width of the outer heat-insulating outer wall and the roof base panel in the short side direction, so that the rib-shaped projections are not continuous when they are arranged. Alternatively, even if there is a ventilation fan or other equipment opening, the structure is such that convection air easily flows into the left and right spaces (E) under windows and openings, so that convection of warm air is not hindered.

  The narrow rib-less base panel used around the opening such as a sash has the following structure. A structural support portion (A ') for fixing to a wooden frame or the like is firmly fixed inside the thin plate (1) by integral molding or adhesion, and a heat insulating layer (C) is adhered or molded inside the thin plate (1) according to the material. Installed by internal firing. The structural support portion (A ') has a through hole (3) for using fixing nails or screws, and a fixing outer frame (G) such as a fitting is attached to the outside of the thin plate (1). To be fixed.

  In order to prevent dew condensation on the surface of the panel due to the temperature difference between the inside and outside, the insulation performance is not impaired, and the outer insulation outer wall and the roof base panel are waterproofed and embalmed on the front and back and all the edges, and the vertical and A notch is provided in the horizontal joint to prevent rainwater that has penetrated the external finishing material from being guided downward in the space (E) outside the panel, discharged at the lowest part, and penetrated inside. And

  By using the base panel of the present invention, the outer heat insulation method of the outer wall and the roof of the wooden and lightweight steel-framed buildings and the like is made simpler and more effective, and a space is provided between the heat insulating layer and the outer finishing material. As a result, it has a function as a heat collecting and exhausting layer of the passive solar system, and enables effective use of solar energy according to seasonal changes.

  The plate-like external finish base (B) and the heat insulation layer (C) are integrated and manufactured according to the standard dimensions according to the reference module, and are directly applied to the wooden frame of the outer wall and roof of wooden and lightweight steel structures. It can be installed, simplify installation work and provide high-performance external insulation.

  FIG. 6 shows an example of installation of an outer heat insulating outer wall base panel of a general outer wall portion having no opening of a wooden building.

  The outer wall base panel for external heat insulation of the present invention is attached to the outside of a wooden frame or the like, and only the structural support portion (A) penetrates the heat insulating layer, thereby minimizing the heat bridge. Further, by changing the pitch of the structural support (A), a heavy external finish can be used.

  Further, by providing a rib-shaped projection (2) also serving as a strong bone for fixing the external finishing material with nails or screws on the outer side of the external finishing base (B), warm air can be generated between the external finishing material and the external finishing material (B).
