[Detailed explanation of the idea]

0001

[Industrial application field]

This invention proposes that when another panel, etc. is attached to the frame or panel of a sound insulating structure, This article relates to anti-vibration panel mounting hardware used when

0002

[Conventional technology]

Conventional sound insulation structure panels are made by connecting and fixing a pair of panel materials with connecting bolts or screws. Because they were integrated or connected and fixed via studs, the vibration of one side material was caused by these connections. It is easy to be transmitted to the other side material through tie bolts, screws, studs, etc., and it is not always sufficient. The sound insulation function could not be fulfilled.

0003 Therefore, we developed a base body with a male thread and a female thread on the inner circumferential surface that engages with the base body. An adjuster consisting of joints is fixed between face materials or panels, and the voids formed there are A structure in which glass wool is inserted into the gap is known (Utility Model Application Publication No. 1-11851). Publication No. 0).

0004 However, the adjuster that makes up this invention is a screw thread provided on the base and adjustment body. attempts to reduce the transmission of vibration by allowing vibration using the spacing between However, vibrations are propagated by contact between the base, which is an inelastic body, and the adjustment body. I couldn't avoid it.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings. first,

Shown in the plan view of Figure 2. As shown in FIG. A rectangular collar-shaped portion 6 extends outward from the lower outer edge of the column. and, Oval mounting holes are formed at the four corners of the brim portion 6.

[0009] Also,

As shown in FIG. 1, the top part 7 of the hat-shaped vibration transmitting body 2 is It is made to protrude from the upper opening surface of the main body 1. In other words, a hat-shaped vibration transmitter A predetermined space is provided between the plane of the top 7 of the hat-shaped body 1 and the upper opening surface of the hat-shaped body 1. By providing the hat-shaped main body 1, the hat-shaped vibration transmitting body 2 is attached. It is designed to avoid direct contact with surface materials or panels.

0010 The top 7 of the hat-shaped vibration transmitting body 2 is larger than the diameter of the opening 5 of the hat-shaped main body 1. The diameter of the opening 5 is also small, and the inner edge of the opening 5 and the outer edge of the hat-shaped vibration transmitting body 2 are made small. It is positioned so that there is no contact. In addition, the brim portion of the hat-shaped vibration transmitting body 2 is also The size is such that the outer edge of the hat does not come into contact with the inner circumferential surface of the hat-shaped main body 1.

[0011] First, a vibration-proof rubber elastic body 3 is 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, including the inside of the hat-shaped vibration transmitting body 2 until it reaches the plane of the brim of the hat-shaped main body 1. The vibration-proof rubber elastic body 3 is filled with. As a result, the vibration is transmitted from the hat-shaped vibration transmitting body 2. The acoustic vibration generated by the hat-shaped body 1 and the hat must be transmitted only through the vibration-proof rubber elastic body 3. Acoustic vibrations are reliably attenuated because the sound vibrations are transmitted to the frame, etc. to which the toe-shaped body is attached. It will be done.

[Fig. 3] A gypsum board is attached to a panel made of lightweight aerated concrete through the hardware of this invention. FIG. Screw the tapping screw 11 into the top 7. However, the screwing position is not necessarily limited to the center as long as it touches the top 7. do not have. This tapping screw is screwed into the vibration isolating rubber elastic body 3, so it will take some time. length is required. For example, when the hat-shaped vibration transmitting body 2 is made into a planar shape , the distance from that plane to the plane of the brim of the hat-shaped body 1 is considerably large. Therefore, the entire mounting hardware becomes quite thick. This invention is a vibration transmitter By making it hat-shaped, the top 7 reaches the plane of the brim of the hat-shaped main body 1. It is possible to easily secure the distance between be able to. In addition, 12 is a so-called post-installed anchor, which is installed on the collar 6. Adjust the position of the oval shaped mounting hole to fit this anchor and fix it with bolt 13. ing.

[0013] In addition,

As shown in FIG. 1, a vibration-proof rubber elastic body 3 is filled inside the hat-shaped body 1. Although acoustic vibrations are considerably attenuated even if

As shown in FIG. 4, the top 7 Also between the outside of the panel and the facing material or panel, etc. and between the brim portion 6 and the frame or panel, etc. If separate anti-vibration rubber elastic bodies 14 are bonded to each other, acoustic vibration can be further reduced. The decay effect will increase.

[0014] In this embodiment, the hat-shaped main body 1 and the hat-shaped vibration transmitting body 2 are hollow cylinders. Although the shape is centered on hardware, it is not necessarily limited to this, and the purpose of this invention is It may also have a shape such as a prism within a range that does not deviate from the above. Further, the brim portions of the hat-shaped main body 1 and the hat-shaped vibration transmitting body 2 are also limited to square shapes, etc. Any shape may be used without departing from the spirit of the present invention.

[0015] Furthermore, the elastic body constituting the present invention does not necessarily have uniform elasticity. The hardness is not limited to, but is non-uniform, for example, the hardness changes sequentially from one side to the other, so-called There are elastic bodies that have gradient properties such as the above, and elastic bodies that are formed by laminating multiple layers of the same material. The elastic body having the gradient property is impregnated with the vulcanizing agent so that the concentration is higher on the one side. It can be obtained by a method such as heating after heating.

[0016]

[Effect of the idea]

As detailed above, in this invention, one panel is in contact only with the hat-shaped vibration transmitter. However, the acoustic vibration propagated from the top of the hat-shaped vibration transmitter is transmitted through the elastic body. This is transmitted only to the hat-shaped body and the frame to which the hat-shaped body is attached. Acoustic vibrations are incomparable to cases where inelastic bodies such as panels or metal fittings come into contact with each other. The vibrations are attenuated, and extremely small vibrations are transmitted to the brim of the hat-shaped body and the framework. This makes it extremely easy to attach separate parts to the frame or panels of various sound insulation structures. Excellent effect of reducing vibration propagated when panels etc. are installed demonstrate.
