【Example】
Hereinafter, a skirting board according to an embodiment of the present invention will be described with reference to the drawings.
(Example 1)
The skirting board of the first embodiment according to the present invention is a perspective view showing the skirting board of the first embodiment of FIG. 1 viewed from the back side, and a floor structure using the skirting board of the first embodiment of FIG. Description will be made with reference to the cross-sectional view shown. The skirting board 1 shown in FIG. 1 has a configuration in which a meandering communication passage 1a formed of a continuous groove having a substantially crank shape and communicating vertically is provided on the back surface of the skirting board 1. The meandering communication passage 1a separates the air flowing into the passage from the lower part of the skirting board 1 from right to left in the middle of the passage and merges again as indicated by an arrow in the figure, and flows out from the upper part of the skirting board 1. Thus, an air communication means for communicating the underfloor space and the above-floor space is formed. Further, the floor structure shown in FIG. 2 has a plurality of support legs 21 erected at predetermined positions on a floor base 20, a laterally extending joist 23 is placed on the support legs 21, and a wall 26 attached to a wall base 24. A gap 32 is provided between the floor 25 and the floor 25, the floor 25 is placed on the joist 23, and the baseboard 1 is attached and finished by concealing the gap 32 near the wall.
The baseboard 1 used in the floor structure allows the air in the underfloor space 30 to escape from the gap 32 to the overfloor space 31 via the meandering communication path 1a as the air communication means, and to compress and expand the air sealed under the floor. Has been prevented. It should be noted that air flows from the floor below the floor during compression and from the floor above the floor during expansion through the gap 32 and the meandering communication path 1a. That is, in order to prevent the drum phenomenon, air flows in and out. It is necessary to do. Strictly speaking, the air communication means for taking in and out of air is a space (passage) formed by the meandering communication passage 1a and the wall 26 closing the meandering communication passage 1a. The space is interpreted as air communication means in a broad sense, and the meandering communication passage 1a is interpreted as air communication means in a narrow sense.
In the skirting board 1 having the above configuration, the meandering communication passage 1a collides with the air diverted from the other passage when the air that has flowed from under the floor is bent in the middle and diverted to the left and right to merge again. And other airflow resistance. This ventilation resistance prevents the underfloor sound contained in the air from being transmitted directly to the floor, and has the effect of reducing indoor noise. That is, according to the configuration of the first embodiment, the meandering communication passage 1a of the skirting board 1 communicates the underfloor space 30 and the above-floor space 31 to prevent a so-called floor drum phenomenon and to release the underfloor sound that escapes with air. A skirting board that suppresses direct propagation to the vehicle and reduces indoor noise can be provided.
As the baseboard 1 of the first embodiment, for example, there is a baseboard made by pasting a decorative sheet as a covering material on a particle board as a baseboard body. If the baseboard body is a particle board which is a kind of compression-molded material, the meandering communication passage 1a formed of a continuous crank-shaped groove can be easily formed on the back surface of the particle board. It can be said that it is preferable from the point of view. However, it is also possible to manufacture the skirting board of this embodiment by carving the meandering communication passage 1a in a solid board.

At this time, a gap 32 is provided between the wall 26 attached to the wall base 24 and the floor 25. Then, the baseboard 2 is attached to the side of the wall so as to hide the gap 32.
The baseboard 4 used in this floor structure allows the air in the underfloor space 30 to escape from the gap 32 to the above-floor space 31 via the meandering communication passage 4a, thereby preventing the air from being compressed and expanded. In addition, in the floor structure of the "Kiwa no joseki method", the support leg 17 is composed of a nut 17a, a bolt 17b, and a rubber seat 17c. Then, the tip of the nut 17a is fitted on the floor 25. In addition, the rubber seat 17c has a function of alleviating an impact when the vehicle falls down on the floor. Incidentally, the skirting board 2 may have a configuration in which the front skirting board 3 and the rear skirting board 4 are fixed in advance with an adhesive or the like. May be fixed later.
In the skirting board 2 having the above structure, the meandering communication passage 4a divides the air flowing through the passage to the left and right in the middle of the passage as shown by the arrow in FIG. 3, and collides with the air diverted from the other passage. Works to reduce the flow energy of air. By this function, the direct propagation of the underfloor sound that escapes with the air onto the floor is suppressed, and an effect of reducing indoor noise is obtained. That is, according to the configuration of the second embodiment, the meandering communication passage 4a of the skirting board 2 communicates between the underfloor space and the overfloor space to prevent amplification of floor vibration, and directs the underfloor sound that escapes with air onto the floor. A skirting board that suppresses propagation and reduces indoor noise can be provided.

The upper portion of the meandering communication passage 1a corresponds to an air outlet from which air from under the floor flows out onto the floor.
By the way, in order to prevent the drumming of the floor, it is necessary that air be taken in and out, and the ventilation resistance means 6 is a member that allows air to pass from “below the floor to above the floor” and “from above the floor to below the floor”, that is, reversible ventilation. A member having properties is desired. Therefore, the ventilation resistance means 6 is a soft member having reversible air permeability, such as a nonwoven fabric, felt, glass wool, or a continuous foam of synthetic resin. Further, it is preferable that the ventilation resistance means 6 is fixed to the meandering communication path 1a with an adhesive or the like.

In the skirting board 5 of the third embodiment, if the ventilation resistance means 6 is provided at the upper part (or the uppermost part or the air outlet part) of the skirting board 1 to close the meandering communication path 1a, the indoor space can be improved. The effect of preventing dust from entering the inside of the baseboard can be obtained. However, the object of the present invention can be achieved by closing the meandering communication passage 1a regardless of the arrangement of the ventilation resistance means 6, so that the invention is not limited to the arrangement at the top. On the other hand, for example, a configuration in which the meandering communication passage is closed by a non-breathable fin member can be said to be unfavorable because the reversible breathability is impaired even though it serves as ventilation resistance means.
