Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drainage member used in an exterior wall ventilation construction method.

[Background technology]

As shown in Figures 1 and 2, the conventional draining member forms a first horizontal piece A which bends outward in the middle of a vertical plate, and bends this first horizontal piece A downward. A draining member has been widely used, which includes a hanging plate (C) and a draining plate (C) formed by bending the hanging plate outward. At this time, a ventilation hole D was provided in the first horizontal piece A. However, such a drainage member has a drawback in that during a rainstorm, rainwater enters through the ventilation holes in the first horizontal piece A, and the rainwater may rot the inner wall surface. In addition, since the outer wall material E cannot be placed on the drainage member, it takes time and effort to align the upper and lower positions.

[Purpose of invention]

The present invention was developed in view of the above-mentioned background technology, and its purpose is to provide a baffle plate to cover the drainage member so as not to block the ventilation hole, and also to form an external wall board mounting part to prevent rain. To provide a draining member that improves performance and facilitates vertical positioning during construction of exterior panels.

[Disclosure of invention]

3 and 4 show draining members according to different embodiments of the present invention, which will be described below.

In A, a vertical plate is used as a mounting piece 1, and a horizontal piece 2 is provided protruding from the inside of this mounting piece, and the inner end of this horizontal piece 2 is bent downward to form a hanging piece 3. In a draining member consisting of a water cutting piece 4 whose lower end is formed by protruding outward from the lower end of the mounting piece 1, a ventilation hole 5 is formed in the horizontal piece 2, and the ventilation hole 5 in the horizontal piece 2 is formed. This draining member is formed by providing a baffle plate 6 below the horizontal piece 2 so as not to block it, and forming an outer wall board mounting part 7 extending horizontally outward from the lower end of the mounting piece 1.

B is also a draining member formed in the same manner as described above and having baffle plates 6 disposed in an inverted V-shape.

FIG. 5 and FIG. 6 are diagrams showing the state in which the above-mentioned drainage members A and B are installed, and will be described below.

A foundation 9 is placed on a foundation 8 made of concrete etc.
After fixing, a plurality of vertical furrings 11 are arranged and fixed to the pillar 10, and the draining member A or the draining member B is nailed below the vertical furrings 11. Thereafter, the outer wall boards 12 made of cement, calcium silicate, etc. are placed on the outer wall board mounting portions 7 of the drainage members A and B, and nailed to the vertical rims 11.

Therefore, air infiltrates as shown by the arrow and forms the vertical rim 1.
1 and the outer wall board 12 through the ventilation hole 5, and flows out from the direction of the eaves. Rainwater during a rainstorm or the like is stopped by a baffle plate 6 before it enters the ventilation holes 5 of the drainage members A and B.

[Effect of idea]

A baffle plate is provided on the draining member to prevent the ventilation hole from being blocked, and an external wall board mounting area is provided to facilitate ventilation between the outside and the wall. It is possible to prevent the infiltration of water and improve the ability to shut off rain. In addition, vertical positioning during construction of the exterior wall board can be facilitated by the exterior wall mounting portion.
Further, since the draining plate which is inclined downwardly on the outside projects from the mounting piece, rainwater flows smoothly downward, and it is possible to prevent rainwater from entering the ventilation hole.
