Description

[Detailed Description of the Invention] The present invention relates to a field board, and its purpose is to provide a field board having ventilation and moisture permeability.

Conventionally, plywood such as 8 to 12 mm concrete panels has been used as the field board, but because the field board itself has no air permeability or moisture permeability, it is difficult to connect the field board and the roof base material during cold seasons such as winter. There was a possibility of condensation occurring between the two.

The present invention is provided to solve the above-mentioned problems, and will be explained below with reference to examples.

As shown in FIG. 1, the board 1 has a large number of holes 2 formed on its front and back surfaces to communicate the hollow inside with the outside as shown in FIG.

Inside the board 1, a partition plate 3 is arranged horizontally so as to be parallel to the front and back surfaces of the board 1.
The upper and lower spaces are communicated at both ends.

Partition plates 5 are installed at predetermined intervals between the partition plate 3 and the board 1 to support and fix the partition plate 3 and to form a plurality of small partitions 4 in the horizontal direction between the partition plate 3 and the board 1. The partition plate 5, the board 1, and the partition plate 3 are fixed by, for example, an adhesive or nailed.

A hole 2 is opened in the small partition 4 to connect the outside and the small partition 4.
are communicating.

In addition, horizontal ventilation holes 6 are formed in the partition plates 5 at positions above the lower end of the partition plates 5, respectively, to communicate the small partitions 4 in the horizontal direction.

Further, inside both sides of the board 1, a small partition 4' is provided, which is partitioned by a partition plate 5 on one side and a side wall of the board 1 on the other side.
The upper and lower small partitions 4', 4' communicate with each other through holes made through the partition plate 3.

As shown in FIG. 2, the small partitions 4', 4' are not provided with holes 2 on the front and back surfaces of the board 1.

Therefore, air and moisture entering through the holes 7 on the surface of the board 1 pass through the small compartment 4 and the side ventilation hole 6 in order, and then pass through the board 1.
is discharged from the hole 2 on the back side.

Furthermore, even if dew condensation occurs and water droplets 8 enter the small partition 4 through the holes 2, they are blocked by the partition plate 5 and prevented from coming out through the holes 2 on the back surface of the board 1.

The arrows in FIGS. 2 and 3 indicate the flow of air and moisture.

In this invention, a partition board is installed horizontally inside a board that is hollow and has many holes communicating with the inside on the front and back sides, and the internal space of the board is divided into upper and lower parts. A plurality of partition plates are erected at predetermined intervals between them to create a large number of small partitions separated by adjacent partition plates, partition plates, and boards,
In addition to providing horizontal ventilation holes that pass through the small partitions adjacent to the partition plates of these small partitions, at least the opening edge of the lower end of the horizontal ventilation hole of the partition plate disposed on the upper surface side of the partition plate is Since it is set to be located above, even if dew condenses on the upper side (surface side), the water droplets can be dammed up between the partition plates on both sides of the small compartment below the lower opening edge of the side ventilation hole. In addition, it is constructed as described above, and is partitioned by the partition plate on one side and the side wall of the board on the other side. Since the small compartments on both sides of the board without holes are communicated through the partition plate, it is possible to provide ventilation and moisture permeability between the front and back sides of the board, making it easy to use. This has the effect of preventing dew condensation from forming between the board and the roof base material.
