Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to interior panels for tunnels, etc., and more specifically for automobile tunnels, parking lots, etc. This invention relates to interior panels that are attached to the walls of areas where automobiles drive.

0002

[Conventional technology]

Traditionally, inorganic boards with an inorganic paint applied to the surface have been used as interior boards for tunnels, etc. has been used. The reason why inorganic paint is applied to the surface of an inorganic board is that Unlike organic paints, machine paints do not emit toxic gases when burned, and they also reduce the emissions of automobiles. The paint film is less likely to deteriorate due to gas, and inorganic paints have a denser paint film than organic paints. This is because it is hard and does not easily cause scratches on the painted surface.

0003

[Problem that the idea aims to solve]

However, as mentioned above, the film of inorganic paints is dense and hard, so they do not absorb the sound of cars running. If the occupants feel uncomfortable due to the echoing sound from the inorganic plate, which has the property of being highly reflective, Also, the painted surface made of inorganic paint has poor toughness, so it can be splashed by cars. The problem is that cracks are likely to occur on the painted surface when the inorganic plate vibrates when it is hit by stones etc. There is a problem.

0004 In view of the above, the present invention is an interior board for tunnels etc. whose surface is coated with inorganic paint. Despite this, there is little reflection of the sound of cars running, and even if stones hit the painted surface, there will be no scratches on the painted surface. The purpose is to make it difficult for cracks to occur.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the present invention has an opening that penetrates the inorganic plate in the front and back directions. By providing a The sound is guided to the back side of the inorganic board and is absorbed by the porous board. It absorbs the vibration energy of the structural plate.

[0006] Specifically, the solution taken by this invention is to install it on the walls of tunnels etc. where cars drive. Inorganic board with inorganic paint applied to the surface, intended for interior boards of tunnels etc. and a porous plate integrally laminated on the back side of the inorganic plate, and the inorganic plate has An opening consisting of multiple through holes lined up in the vertical direction or slits extending in the vertical direction A plurality of porous plates are arranged in parallel, and the surface of the porous plate communicates with the opening and is continuous in the vertical direction. The structure is such that a concave groove is provided.

[0007]

[Effect]

With the above configuration, the sound of the car running is transmitted through the multiple through holes provided in the inorganic board. Or, after passing through the opening made of slits and reaching the back side of the inorganic plate, Since it absorbs more sound, the reflection of running sound on the surface of the inorganic board is reduced.

[0008] In addition, since the porous plate is integrally laminated on the back side of the inorganic plate, it is possible to The vibration energy of the inorganic plate that is generated when it is hit by something like this is absorbed by the porous plate. This makes it difficult for the inorganic board to vibrate and prevents the inorganic paint applied to the surface of the inorganic board from vibrating. Cracks are less likely to occur on painted surfaces.

[0009] Furthermore, the surface of the porous plate communicates with the opening of the inorganic plate and is continuous in the vertical direction. Since the grooves are provided, even if water or contaminants enter the openings of the mineral board, These water and pollutants do not remain in the opening but flow downward through the groove. .

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings.

[0011] FIG. 1 is an exploded perspective view of an interior panel A of a tunnel or the like according to an embodiment of the present invention. , In the same figure, 10 is an inorganic plate constituting the front side part of the interior panel A, and 12 is an A porous plate that is integrally laminated on the back side of the inorganic board 10 and constitutes the back side portion of the interior board A. An inorganic paint is applied to the surface of the inorganic plate 10.

0012 Examples of the inorganic board 10 include a calcium silicate board, a fiber-reinforced cement board, and a gypsum slurry board. A log board etc. can be used.

[0013] Inorganic paints include silicone, titanium, aluminum, etc. modified with alkyl groups. The main components are hydrogenated metal alkoxides, water glass, etc., and titanium oxide, etc. are added to the main components. A material to which a pigment is added can be used as appropriate.

[0014] As the porous board 12, glass wool fiberboard, rock wool fiberboard, aluminum foam board, foam glass, calcium carbonate filled vinyl chloride resin foam board, etc. , materials having fire prevention performance at least higher than semi-noncombustible materials can be used as appropriate.

[0015] As shown in FIG. 1, the inorganic plate 10 has a plurality of rows of through holes 14 arranged in the vertical direction. are provided at approximately equal intervals in the horizontal direction. The diameter of the through hole 14 is determined by the diameter of the inorganic plate. 15 mm or less from the viewpoint of maintaining the strength of the inorganic plate 10 and the light reflectivity of the surface of the inorganic plate 10. In particular, it is preferably 7 mm or less, and 3 mm or more from the point of view of passing vehicle sounds. It is preferable that there be.

[0016] In this way, a plurality of through holes 14 are provided in the inorganic plate 10, and the inorganic plate 10 is provided with a plurality of through holes 14. Since the porous plate 12 is laminated on the back side, the sound of the car is transmitted through the through holes 14. After reaching the porous plate 12, the sound is absorbed inside the porous plate 12.

[0017] Moreover, since the porous plate 12 is integrally laminated on the back surface of the inorganic plate 10, the inorganic The vibration energy of the inorganic plate 10 generated when a stone or the like hits the quality plate 10 is due to the porous Since the plates 12 absorb stones, stones etc. thrown away by cars are absorbed by the inorganic plate 1. Even if it hits zero, the inorganic plate 10 hardly vibrates. For this reason, it is coated on the surface of the inorganic board 10. The treated inorganic paint is less likely to crack.

[0018] As shown in FIG. 1, the surface of the porous plate 12 has vertical rows of through holes 14 and Concave grooves 16 communicating with through holes 14 correspond to rows in the horizontal direction and are arranged vertically and horizontally. It is located in the opposite direction. The width of the groove 16 is slightly larger than the diameter of the through hole 14. It is preferable that the

[0019] In this way, grooves 16 communicating with the through holes 14 are provided on the surface of the porous plate 12. Because of this, water and contaminants that have entered the inside of the through hole 14 are It flows horizontally and vertically through the concave grooves 16 without stagnation in the interior. It falls below plate A.

[0020] FIG. 2 is an exploded perspective view of an interior panel A of a tunnel, etc. according to a modified example. In this case, instead of the through hole 14, a slit 18 extending in the vertical direction is provided approximately equally in the left and right direction. In addition to being provided at intervals, the surface of the porous plate 12 corresponds to the slits 18. A concave groove 16 extending vertically and communicating with the slit 18 is provided. . As with the through hole 14, the width of the slit 18 is set to maintain the strength of the inorganic plate 10. From the viewpoint of light reflectivity of the surface of the inorganic plate 10, 15 mm or less, particularly 7 mm or less is preferable. 3 mm or more is preferable from the viewpoint of passing vehicle sound.

[0021] The operation and effect of the slit 18 provided as described above is the same as that of the through hole 1 of the above embodiment. It is almost the same as 4.

[0022] Figure 3 shows construction when fixing interior panel A according to the above embodiment to wall surface B of a tunnel etc. FIG. 3 is a cross-sectional side view showing the method.

[0023] First, as shown in the figure, the porous plate 12 is connected to the upper edge of the back surface of the inorganic plate 10. A decorative board A that is not laminated on the portion 10a and the lower edge portion 10b is prepared in advance. In addition, In the figure, 19 is a layer of inorganic paint applied to the surface of the inorganic plate 10.

[0024] Next, the upper edge 10a and the lower edge of the inorganic plate 10 on the tunnel wall surface B 10b and a bracket 22 having an L-shaped cross section. and anchor bolts 24.

[0025] Thereafter, the upper edge 10a and the lower edge 10b of the inorganic plate 10 are shown on the furring 20. Fix with screw bolts, etc. As described above, the inorganic plate 10 is made porous. The reason why the plate 12 is attached to the rim 20 without intervening is that the porous plate 12 is elastic. Therefore, when the porous plate 12 is interposed between the inorganic plate 10 and the rim 20, , the surface of decorative board A is not flush and the strength of the attachment part of decorative board A is not sufficient. This is because there are cases.

[0026] In addition, in the above construction method, the decorative board A is attached to the upper edge 10a and the lower part of the inorganic board 10. Although it was fixed to the tunnel wall B only at the end edge 10b, the length of the decorative board A in the vertical direction is large, the porous plate 1 is placed in the center of the back surface of the inorganic plate 10 in the vertical direction. 2 is not laminated, and a tunnel is provided through the trunk rim 20 in this region as well. It is preferable to fix it to the wall surface B of.

[Effect of the idea]

As explained above, according to the interior board for tunnels, etc. according to the present invention, it is possible to The sound passes through the opening provided in the inorganic board and reaches the back side of the inorganic board, becoming a porous board. Because it absorbs more sound, the reflection of running sound on the surface of the inorganic board is reduced, making it easier for passengers to It is possible to reduce the discomfort caused by echoed sounds from the interior panels.

[0028] In addition, a porous plate with vibration absorption properties is integrally laminated on the back side of the inorganic plate. Therefore, the inorganic board becomes difficult to vibrate even if it is hit by stones, etc., so Cracks are less likely to form.

[0029] Furthermore, the surface of the porous plate communicates with the opening of the inorganic plate and is continuous in the vertical direction. Since grooves are provided, water and contaminants that have entered the openings of the inorganic board will be removed from the openings. Because water and contaminants fall downward through the grooves without remaining in the inorganic To prevent stains on the interior board surface caused by water flowing down the surface of the quality board. can be done.
