Description

[Detailed description of the invention]

[0001] The present invention provides an acoustic vibration used when another panel or the like is attached to a frame or a panel in a sound insulating structure.
The present invention relates to a damping panel mounting hardware.

[0002]

2. Description of the Related Art In a conventional sound insulation structure panel or the like, a pair of face materials are connected and fixed by connecting bolts or screws, or they are connected and fixed via studs. It easily transmitted to the other face material via screws, studs, etc., and could not necessarily achieve a sufficient sound insulation function.

[0003] Therefore, an adjuster comprising a base having a male screw portion and an adjuster having a female screw screwed into the base member on the inner peripheral surface is engaged between face materials or panels, and glass wool is inserted into a gap formed there. A known structure is known (Japanese Utility Model Laid-Open No. 1-118510).

[0004] However, the adjuster of the present invention is designed to make it difficult to transmit the vibration by permitting the vibration by using the interval between the thread provided on the base and the adjusting body. However, it was not possible to prevent vibrations from being propagated due to the contact between the base and the adjustment body.

[0005]

An invention To solve the above problems, the present inventor has conducted extensive studies for the purpose of obtaining a new panel mounting hardware that can be used for attenuation of the acoustic vibrations of at panel on various sound insulation structure, the present invention Reached.

[0006]

In order to achieve the above object, the present invention provides a hat-shaped body (1) having a top (4) provided with an opening (5) smaller than the outer edge thereof, and the opening (5). 5) a hat-shaped vibration transmitting body (2) whose top (7) protrudes to the outside, the vibration transmitting body (2), the hat-shaped main body (1), and a flat surface (8) of the hat-shaped main body of the hat-shaped main body. And an elastic body (3) filled between the two.

[0007]

In the present invention, one panel is in contact only with the hat-shaped vibration transmitting body, and the acoustic vibration propagated from the top of the hat-shaped vibration transmitting body is transmitted through the elastic body to the hat-shaped main body and the hat-shaped main body. Since the vibration is transmitted to the attached frame, the acoustic vibration is attenuated to a level that is incomparable with the case where inelastic bodies such as panels or metal fittings are in contact with each other, and only minimal vibration is transmitted.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First,

As shown in the plan view of FIG. 2, the hat-shaped main body 1 is provided with an opening 5 in an upper circular flat surface of a cylindrical hollow hardware, and a rectangular brim-shaped portion 6 extends outward from a lower outer edge of the column. ing. Elliptical mounting holes are formed at the four corners of the collar 6.

Also,

FIG. 1 shows a top portion 7 of a hat-shaped vibration transmission body 2.
Are projected from the upper opening surface of the hat-shaped main body 1. That is, the hat-shaped main body 1 attaches the hat-shaped vibration transmitting body 2 by providing a space at a predetermined interval between the plane of the top portion 7 of the hat-shaped vibration transmitting body 2 and the upper opening surface of the hat-shaped main body 1. It does not come into direct contact with face materials or panels.

[0010] This top 7 of the hat-shaped vibration transmitting member 2 is smaller Sana diameter than the diameter of the opening portion 5 of the hat-shaped body 1, yet the outer edges of the inner and hat vibration transmitting member 2 of the opening 5 The position is such that it does not touch. The brim-shaped portion of the hat-shaped vibration transmission body 2 is also sized so that its outer edge does not contact the inner peripheral surface of the hat-shaped main body 1.

A rubber vibration insulator 3 is first filled between the hat-shaped main body 1 and the hat-shaped vibration transmitting body 2 so that the entire hat-shaped vibration transmitting body 2 does not come into direct contact with the hat-shaped main body 1. The vibration-proof rubber elastic body 3 is filled up to the flange-shaped flat surface of the hat-shaped main body 1 including the inside of the vibration transmitting body 2. Accordingly, the acoustic vibration transmitted from the hat-shaped vibration transmission body 2 is transmitted to the hat-shaped main body 1 and the frame to which the hat-shaped main body is attached only through the vibration-proof rubber elastic body 3. Is surely attenuated.

[0012]

FIG. 3 is a cross-sectional view showing a state in which a gypsum board is attached to a panel made of lightweight cellular concrete via a hardware of the present invention. A tapping screw 11 is screwed into the top 7,
The screwing position is not necessarily limited to the center as long as it is on the top 7. The tack pink screw 11 needs to have a certain length because it is screwed into the rubber vibration insulator 3. For example, when the hat-shaped vibration transmitting body 2 is formed in a flat shape, a considerable distance from the flat surface to the flat surface 8 of the hat-shaped main body 1 must be taken, and the whole mounting hardware is considerably large. Of thickness. In the present invention, since the vibration transmitting body is formed in a hat shape, a distance from the top 7 to the flat surface 8 of the hat-shaped main body 1 can be easily secured, and the thickness of the entire mounting hardware can be reduced. While increasing the sound vibration damping effect
You . Reference numeral 12 denotes a so-called post-installed anchor, which adjusts the position of an elliptical mounting hole provided in the brim-shaped portion 6 so as to match the anchor, and fixes it with bolts 13.

In addition,

As shown in FIG. 1, even if only the inside of the hat-shaped main body 1 is filled with the vibration-proof rubber elastic body 3, the acoustic vibration is considerably attenuated.

As shown in FIG. 4, different vibration-proof rubber elastic bodies 14 are bonded between the outside of the top 7 and the face material or panel and between the brim-shaped portion 6 and the frame or panel or the like. By doing so, the effect of damping the acoustic vibration is further enhanced.

In this embodiment, the hat-shaped main body 1 and the hat-shaped vibration transmitting body 2 have a shape centered on a cylindrical hollow metal member, but are not necessarily limited to this, and do not depart from the spirit of the present invention. , Prisms and the like. Further, the brim portions of the hat-shaped main body 1 and the hat-shaped vibration transmission body 2 are not limited to a square shape, and may have any shape without departing from the spirit of the present invention.

Further, the elastic body constituting the present invention is not necessarily limited to an elastic body having a uniform elasticity, but is non-uniform, for example, the hardness is sequentially changed from one side to the other side.
There is an elastic body having a so-called gradient property or an elastic body formed by laminating the same material in multiple layers. The elastic body having the inclined property can be obtained by a method in which a vulcanizing agent is penetrated so as to have a higher concentration toward the one side and then heated.

[0016]

[Effect of the invention] As described in detail above, the hardware of the invention is:
