Description

  The present invention relates to a base panel for wall finishing used by attaching between pillars of a wooden building.

For finishing a wall surface of a wooden building, a method of covering the surface of a base component attached along the wall surface with a surface finishing material such as mortar, siding, plaster, or earth coating is generally employed.
Conventionally, as a wall base plate used for earthen wall base, a thin narrow plate is opened with a large number of square square holes, and the narrow plates are stacked vertically and bonded together with adhesive and nail hammering. A manufactured Komaidai wall base plate for earth wall is known (see Patent Document 1).
This well-known technique is very strong and can be used to reinforce the bracing of the walls by combining the narrow plates vertically and diagonally, and also helps to reinforce the bracing of the walls, making the building structurally strong. It will be.

In addition, while communicating with each other at the intersection of the belt-shaped narrow plates constituting the front side base plate and the back side base plate, and having a large gap volume, the air located in the gap is moved in the vertical direction and the horizontal direction. There is known a wall finishing foundation structure that can be smoothly ventilated, and that water leaked through the gap can be quickly removed and easily removed (see Patent Document 2).
In this known technique, a front panel and a back panel are inclined in opposite directions so as to cross each other, and a wall finishing base panel is formed by joining the front base board and the back base board at the intersection. Attach to the structural frame such as pillars and studs provided along the outer wall of the building, and incline in the out-of-phase direction that intersects with each other at the lower end of the wall finishing foundation panel. A ventilation drainage for allowing ventilation to flow into the gap is provided, and the ventilation flown from the ventilation drainage is raised along the gap of the wall finishing base panel and discharged.

Also, there is known a wall finishing base panel that can easily and accurately perform the work of attaching the wall constituent material on the surface side after being mounted between the pillars and can obtain sufficient ventilation and strength. (See Patent Document 3).
This known technique is used by being installed between columns as a base material for finishing a wall of a building, and a plurality of front side strip-shaped narrow boards arranged in parallel at intervals, and arranged in parallel at intervals. A base panel for wall finishing formed by joining and integrating a plurality of backside belt-like narrow plates in a state of crossing each other, wherein the plurality of front-side beltlike narrow plates are installed in a horizontal direction or a vertical direction, and the plurality The back side strip-shaped narrow plate is a base panel for wall finishing attached between columns in a state of being inclined at an angle of 30 to 60 degrees with respect to the front side strip-shaped narrow plate.
