Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the improvement of multi-level parking facilities.

(Prior Art) Hitherto, multi-story parking facilities have been used in which vehicles are housed by circulating the chassis within a steel frame structure surrounded by an outer wall. However, if there are houses (particularly wooden houses) adjacent to this multilevel parking facility, noise disturbances may occur.

(Problem that the invention attempts to solve) In order to prevent noise disturbance when there is a house adjacent to this multi-level parking facility, increasing the transmission loss of the exterior wall panels of the parking facility will result in expensive exterior wall construction and the weight of the exterior wall. Increasingly, the strength of steel structures had to be improved.

Another method is to build a soundproof wall between neighboring houses, but if the soundproof wall is made of reinforced concrete, the construction cost will be high. Furthermore, when constructing a soundproof wall using a block wall, the height could not be increased for earthquake resistance reasons, and increasing the height required a large-scale foundation similar to that required for installing a high independent wall.

The present invention was developed in view of these points, and its purpose is to use the outer wall of the parking facility as it is,
Another object of the present invention is to enable soundproof walls to be installed at low cost without requiring a large-scale foundation.

(Means for solving the problem) In order to achieve this purpose, this invention provides a multi-level parking facility with a steel frame structure, where soundproofing is required around the parking facility, such as houses adjacent to the multi-level parking facility. The soundproof walls, which are partially placed on opposing surfaces, are attached to the steel structure via elastic bodies such as vibration-proof rubber. The soundproof wall may be attached to the steel structure on the outside of the outer wall by a mounting member that passes through the outer wall.

(Function) We placed a soundproof wall partially on the surface facing the area that requires soundproofing around the parking facility, such as a house adjacent to the parking facility, and attached it to the steel structure, so the entire exterior wall Alternatively, the weight can be reduced compared to a single wall in which a material with high transmission loss is used on only one side of the outer wall, and a standard outer wall can be used. Further, a foundation for the soundproof wall is not required, and the soundproofing effect is improved by constructing a double wall. Furthermore, since the soundproof wall is attached to the steel structure via an elastic material such as anti-vibration rubber, it insulates the transmission of mechanical vibrations from the steel structure to the soundproof wall as the chassis circulates, thereby preventing secondary noise. does not emit.

(Example) Hereinafter, an example shown in the drawings will be described. In Figures 1 to 3, 1 is the boundary line with the road, 2
is a multi-story parking facility in which loaded vehicles are stored by circulating the vehicle platform within a steel frame structure 2b surrounded by an outer wall 2a. 2c is its entrance/exit. Reference numeral 3 indicates a fence provided at the boundary of the site, and reference numeral 4 indicates an adjacent house adjacent to the multi-story parking facility 2, which constitutes the area around the parking facility 2 that requires soundproofing.

Reference numeral 5 denotes a soundproof wall partially disposed on the surface of the outer wall 2a facing the adjacent house 4, that is, a place where soundproofing is required, and attached to the steel frame structure 2b.This soundproof wall 5 has a vertical member 5a and a horizontal member. 5b and soundproof board 5c
are attached with screws 5d.

Reference numeral 6 denotes a mounting portion of the soundproof wall 5, and the soundproof wall 5 is attached to the steel structure 2b via a bracket 6a that protrudes through the outer wall 2a and an elastic body 6b such as vibration-proof rubber attached to the tip of the bracket 6a. It is attached.

Therefore, the soundproof wall 5 is placed only in a portion facing the adjacent house 4 and other areas where soundproofing is required around the parking facility 2, and this soundproof wall 5 is connected to the steel frame structure 2b.
Since the multi-level parking facility is installed in the parking lot, the sound generated from inside the multi-story parking facility is absorbed by the soundproof wall 5, and the sound reaching the adjacent house 4 (the area around the parking facility 2 that requires soundproofing) is significantly reduced. Further, since the soundproof wall 5 is attached to the steel structure 2b via an elastic body 6b such as vibration-proof rubber, machine vibrations transmitted from the steel structure 2b to the soundproof wall 5 are insulated by the elastic body 6b. Soundproof wall 5
Does not generate secondary noise.

The soundproof wall 5 is partially installed outside the outer wall of the adjacent house 4 where soundproofing is required, making it a double wall, so the entire outer wall (even just one side) is made of a single layer with high transmission loss. Compared to a structure made of walls, the weight can be reduced and standard external walls can be used.

Furthermore, since the soundproof wall 5 is attached to the steel frame structure 2b, a foundation for the soundproof wall 5 is not required.

(Effects of the invention) As described above, according to the invention, a soundproof wall is placed partially in the area facing the area where soundproofing is required around the parking equipment, such as a house adjacent to the parking equipment, and this wall is built into a steel frame structure. Since it is attached to the outside air, it is possible to reduce the weight of outside air, use standard external walls, and prevent noise. Moreover, since the soundproof wall is attached to the steel structure through an elastic material such as vibration-proof rubber, it insulates the machine vibrations transmitted from the steel structure to the soundproof wall, and prevents secondary noise from being generated from the soundproof wall. . Furthermore, since the soundproof wall is attached to a steel frame structure, no foundation is required for the soundproof wall.
