Description

Soundproof Wall Auxiliary Entrance for Noise Reduction and Efficient Access Lines {SOUND PROOF WALL}

The present invention relates to a soundproof wall auxiliary entrance, and more particularly, to a soundproof wall for blocking noise of a vehicle by an apartment close to a road, through an auxiliary entrance of a soundproof wall made in consideration of the minimum number of residents in addition to the main entrance of the apartment. Not only to effectively block the propagated noise, but also to the noise barrier and the entrance to the noise barrier for effective noise removal to improve the problem of the applicant 's patent application No. 10-2008-0074023' Noise blocking structure of the sound barrier wall opening '.

In general, the soundproof wall is installed in the apartment house close to the road to effectively block the noise of the vehicle. As described above, the soundproof wall is installed as a fence between the edges of the apartment houses adjacent to the road, that is, between the sidewalks of the road and the apartment houses. A sub entrance is used as a sub entrance.

1 is a view showing the auxiliary entrance to the soundproof wall, at a certain height in order to block the noise generated from the noise source of the road 10, such as a vehicle at the boundary between the apartment house 20 and the sidewalk 30 in the adjacent distance. A soundproof wall 40 is provided, and an auxiliary entrance 41 for use as an auxiliary entrance is optionally formed at any position of the soundproof wall 40.

The auxiliary entrance 41 may be a simple space formed in a size that allows a person's entrance and exit, and by installing a closing door (not shown) there, closing the auxiliary entrance 41 after entering and exiting the auxiliary entrance. Blocks noise that can penetrate from (41).

However, the auxiliary entrance of the soundproof wall to consider the convenience of the residents is to provide a minimum movement to the residents, but there is a problem that the noise of the road is transmitted to the apartment house as it is through the auxiliary entrance.

Of course, even if a door is installed at the subsidiary entrance, a countermeasure was urgently needed because it could be left open by unresponsive actions of children with insufficient attention or adult who could inadvertently pass.

As part of such measures, the applicant has proposed an improvement plan under the name of 10-2008-0074023 'Noise blocking structure of the sound insulation wall opening.'

2 and 3, the method is to block the noise transmitted from the noise source of the road 10 between the road 10 and the adjacent apartment house 20 to minimize the movement of the residents at the same time In the soundproof wall structure in which the opening part 41 is formed,

The outer side of the soundproof wall 40 is installed so as to surround the opening 41 in a space where a person can enter from the one side edge of the opening 41 so as to face the transmission direction of the noise source, and orthogonal to the opening 41 An outer barrier wall 43 having an outer entrance 42;

The inner side of the soundproof wall 40 has a space that a person can enter from the other edge of the opening 41 in the direction opposite to the outer blocking wall 43, is installed in the form surrounding the opening 41, the outside An inner blocking wall 45 having an inner opening 44 in a direction opposite to the outer opening 42 of the blocking wall 43;

Reflecting plate 46 is installed on the inner surface of each of the blocking walls (43, 45) at a predetermined inclination so that the noise transmitted through the outer entrance (42) is reflected back to the exit;

First and second barrier ribs 47a which are installed at the end of the outer barrier wall 43 and the edge of the opening 41 adjacent thereto without interruption of entry and exit to block noise transmitted to the outer entrance 42 side ( 47b), including;

The bottom of the space surrounded by the outer barrier wall 43 and the inner barrier wall 45 is constructed higher than the sidewalk 30, and each entrance 42, 44 is formed with stairs (48, 49) There is a focal point.

However, this conventional auxiliary entrance noise blocking structure has been formed so that the outer barrier wall 43 on the basis of the sound barrier 40 is protruded to the side of the side of the side of the side of the side of the side of the sidewalk rather than the apartment complex site acted as an obstacle. In addition, there is a possibility that a fertilization distance may occur due to complaints such as illegal occupation.

In addition, the conventional auxiliary entrance noise blocking structure may have a high noise blocking effect from the outside, but the copper wire between the inner entrance and the outer entrance by the outer blocking wall and the inner blocking wall is too long, and the inner exit is configured to be deflected into one, so that user convenience The problem was raised.

In addition, since the conventional auxiliary entrance noise blocking structure is limited to re-reflecting the incoming noise by configuring a plurality of reflecting plates, there is a problem in that some noise is not introduced because it is not uniform and does not block all of the disordered noise paths.

Therefore, the present invention is a basic for effectively blocking the noise propagated through the auxiliary entrance of the soundproof wall made in consideration of the minimum number of residents in addition to the main entrance of the apartment in the soundproof wall for blocking the noise of the vehicle to the apartment house close to the road. The purpose of the present invention is to provide a soundproofing structure of a soundproofing wall auxiliary entrance, which of course, does not occupy the structure for the soundproof structure, and also greatly improves the user's convenience by minimizing entry and exit lines of the auxiliary entrance.

The present invention for solving the above problems,

In the soundproof wall structure in which the auxiliary entrance is formed to block the noise transmitted from the noise source of the road between the road and the adjacent apartment house, and to minimize the traffic of the residents,

Forming a narrowing portion having a gradually narrower shape inwardly to minimize the noise transmitted through the auxiliary entrance while simultaneously reflecting the noise from the noise source on both edges of the soundproof barrier auxiliary entrance;

Install a curved central bulkhead enclosing the narrowing part at any proximal point in the apartment house member facing the auxiliary entrance, but noise is not introduced through the auxiliary entrance in connection with the narrowing part at the curved end of the central bulkhead; At the same time protruding the edge to be made the intermediate opening passage between the soundproof walls;

An extension passage wall is formed on both sides of the central partition wall and an inner wall of the soundproof wall, and an inner entrance is formed at the same time;

A sound absorbing panel is attached to the inner wall of the soundproof wall where the extension passage wall starts from the narrowed portion and the side wall of the central bulkhead facing the auxiliary entrance to absorb noise from the auxiliary entrance;

A floor extending from the core hole to the inner entrance of the extension passage wall is higher than the height of the sidewalk, and a staircase is formed at each entrance;

The upper structure of the central bulkhead and the extension passage wall has a feature configured by closing in a closed structure to block the outside air.

When the present invention is applied as described above, the soundproof structure transmitted through the auxiliary entrance is configured to be located in the multi-family housing complex, and the problems and fertilizers that may be generated by the conventional soundproof bulkhead occupied at the delivery site. Not only was it completely removed, but the soundproof structure consisted of two inner entrances symmetrically around the auxiliary entrance, allowing tenants to enter and exit from multiple locations to select the closest exit from their location. Has the advantage that the distance is much shorter than the conventional.

In addition, the soundproof partition wall of the present invention can achieve a more quiet apartment living environment because the noise introduced by the additional installation of the sound absorbing panel can completely eliminate the noise through the process of reflection, absorption and extinction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 of the accompanying drawings is a cutaway perspective view showing the soundproof structure of the soundproof wall auxiliary entrance according to the present invention, Figure 5 is a plan cross-sectional view of FIG.

The present invention blocks the noise transmitted from the noise source of the road 10 between the road 10 and the adjacent multi-unit house 20, and at the same time, the soundproofing of the auxiliary entrance 410 additionally installed to minimize the movement of the residents In addition to effective noise blocking in the structure, there is a constitutive key point to ensure the convenience of the tenant to enter and to ensure the safety of pedestrians passing through the sidewalk.

In detail, an embodiment of the present invention, as shown in Figures 4 and 5, through the auxiliary entrance 410 and at the same time re-reflecting the noise from the noise source on both edges of the soundproof wall 400, the auxiliary entrance (410) In order to minimize the transmitted noise to form a narrowing portion 412 of the width gradually narrowed inward direction.

In addition, the central partition wall 420 is formed in a curved shape as if the enclosing portion 412 is wrapped at any proximal point in the multi-family member facing the auxiliary entrance 410.

The edge 421 at the curved end of the central bulkhead 420 is connected to the narrowing part 412 to prevent noise from flowing through the auxiliary entrance 410 and to create an intermediate opening passage 440 between the soundproof walls 400. ) To protrude.

In addition, the L-shaped passages are formed on both sides of the central partition wall 420 and the inner wall of the soundproof wall 400, and at the same time, the extension passage walls 450a and 450b are formed to be provided with two inner entrances 460.

And the inner wall of the soundproof wall 400 in which the sound passage of the noise flowing through the auxiliary entrance 410 is removed at a proper position, that is, through the narrowing part 412, so that the sound wave of the noise flowing through the auxiliary entrance 410 is removed. The sound absorbing panel 470 is attached to the sidewall of the central partition 420 facing the auxiliary entrance 410 so as to absorb the noise coming from the auxiliary entrance 410.

The floor extending from the core hole 430 to the inner entrance 460 of the extension passage walls 450a and 450b is formed higher than the height of the sidewalk, and each of the entrances 410 and 460 has stairs 480a and 480b. It is desirable to form the reason for not only to prevent various foreign substances (garbage) that are broken in India into the apartment complex, but also to prevent rainwater on the sidewalks from entering the complex during the rainy season.

On the other hand, although not shown in detail in the upper structure of the central bulkhead 420 and the extension passage wall (450a, 450b) is preferably closed to the closed structure closed to the outside for the complete block of noise.

In the present invention configured as described above, the narrowing portions 412 formed at both edges of the auxiliary entrance 410 are symmetrically formed at a predetermined inclination angle such that a person does not interfere with the entrance and exit, and the narrowing portion 412 is the auxiliary entrance 410. Its purpose is to minimize the amount of sound wave transmission by narrowing the width and primarily reflecting noise from roads and sidewalks.

On the other hand, the sound wave that is not reflected by the narrowing portion 412 hits the sound absorbing panel 470 of the concave center partition wall 420 while absorbing a portion of the sound wave intensity decreases. The sound wave whose intensity is reduced may be introduced into the inner space of the extension passage walls 450a and 450b through the intermediate opening passage 440 through the disordered path, but again, the sound absorption is installed on the inner wall of the soundproof wall 400 of the inner space. As the intensity of the panel 470 is lowered and absorbed again, the sound wave is completely blocked from being transmitted through the inner entrance 460.

The edge 421 is the sound wave inflow angle in order to block the sound wave flowing through the auxiliary entrance 410 in conjunction with the narrowing portion 412 is transmitted directly to the central opening passage 440 without passing through the central partition 420. Because it is formed in a narrower state, even if the disordered path of the sound wave is placed on the influence of the sound absorbing panel 470 installed in the central partition 420 and the soundproof wall (400).

Further, in the present invention, since the inner entrances are formed to be symmetrically formed with respect to the center partition wall 420, the convenience of the occupants entering and exiting is further increased.

In addition, the soundproof structure of the present invention is not only to be located in the multi-family complex site, but also formed in a symmetrical form, to ensure the safety of the pedestrians passing through the sidewalk and to secure the minimum access to the residents.

In addition, in the soundproof structure of the present invention, the bottom of the space surrounded by the central partition 420 and the extension passage walls 450a and 450b is constructed higher than the sidewalk 30, and each entrance 410 and 460 has a staircase By forming 480a) and 480b, not only the waste at the bottom of the sidewalk can be prevented from entering the site, but also rainwater that has blown up the sidewalk during the rainy season can only be penetrated into the site.
