Description

[Detailed description of the invention] This invention can be used in construction, for example, when fixing wall panels to pillars (including studs), ceiling panels to slabs, and floor panels to joists or joists. The present invention relates to a vibration isolating material for construction, which is used by being sandwiched between a construction board and a building structure in order to improve sound insulation when the construction board is fixedly connected to the construction structure.

Conventional vibration-proofing materials of this type have various shapes, such as textured surfaces or grooves, to improve their vibration-proofing performance. This is a one-piece piece with a thickness of about 10 to 20 mm, and it is sandwiched between the plate P and the structure A, as shown in Figure 1 A [for walls] and B [for ceilings]. By using a nail B etc. and passing it through the vibration isolating material 01, the plate P is attached to the structure A.
It was fixed to. As a result, the wood screws and nails formed acoustic bridges, resulting in a significant drop in sound insulation performance.

Therefore, instead of using wood screws or nails, which are the factors that cause acoustic bridges to form, a method of fixing the bridge using adhesive could be considered, but it is necessary to hold the position until the adhesive completely hardens. jigs are required, which is disadvantageous in terms of construction.

In addition, as a vibration damping agent that does not form an acoustic bridge and can be fixed without using an adhesive, a steel member 01b and a structure equipped with a fixture for the plate material P, as shown in FIG. A steel member 01b equipped with a fixture for A and a vibration isolating rubber 01
There has also been a special vibration isolator 01 that has been bonded via the steel member 01b, but in this case, the size of the vibration isolator increases by the thickness of the steel member 01b, which has the disadvantage of unduly narrowing the indoor space. However, it also had the disadvantage that it was time-consuming to install, as it required the use of hanging metal fittings and the need to drill holes for bolts to pass through.

In view of these circumstances, an object of the present invention is to provide a vibration isolating material for construction that can be made thinner and easier to construct, while also eliminating acoustic bridges and improving sound insulation performance.

The architectural vibration isolator according to the present invention configured to achieve the above object is used as described in detail at the beginning, and is made of an elastic material and has a mounting surface that is fixed to a building board. It is composed of a vibration isolating member and a vibration isolating member made of an elastic material and having a mounting surface that is fixed to the architectural structure, and one of the two vibration isolating members has a recess that widens in depth. , and the other vibration isolating member is capable of being fitted into the deep-spreading recess, and is capable of being moved in a direction perpendicular to the board surface of the construction board by contacting with the inner surface of the recess. A convex portion having a surface regulated by is formed, and both of the vibration isolating members are configured to be able to be fitted and connected to each other.

In other words, we do not use any steel or long bolts that are found in the special anti-vibration materials mentioned above. Since the vibration isolating material itself having the required thickness can be divided into two in the thickness direction, the whole can be made relatively thin and can be used without unduly narrowing the indoor space.

Furthermore, both vibration isolating members can be attached to the plate material and the structure separately, and then both vibration isolating members can be connected by fitting the concave portion and the convex portion. There are no factors that cause acoustic bridges, and the board can be easily fixed and connected to the structure with improved sound insulation performance, which is particularly advantageous when fixing the board to a wall or ceiling. .

The embodiments of the present invention will be described below in detail based on the drawings. They are usually 5 to 10 cm square, with a wall thickness of 1 to 1.5 cm, and
The vibration isolating material 1 made of natural rubber or synthetic rubber having a shore hardness of 50 to 80 is divided into two equal parts in the thickness direction, and the divided vibration isolating members 1A and 1B are
has flat or nearly flat mounting surfaces 1a and 1b, and is provided with hammers, etc., at fixed intervals vertically and horizontally on the opposing surfaces of the divided vibration isolating members 1A and 1B, respectively, as shown in FIG. A concave portion 2A and a convex portion 2B are integrally formed, and the concave portion 2A has a larger diameter toward the back, and the convex portion 2B has a larger diameter toward the tip. has been done.

Then, as shown in FIG. 4A, the mounting surfaces 1a and 1
The divided vibration isolating member 1A is brought into close contact with the entire surface of b.
and 1B in advance using nails or wood screws B, B, and then hammering in the concave portion 2A and convex portion 2B of both divided vibration isolating members 1A and 1B using a hammer or the like, as shown in FIG. The plate material P is fixedly connected to the structure A as shown in FIG. Also, as shown in Figure 5 A and B, if the structure A is a ceiling slab, construction can be carried out in the same manner as above, but especially in this case, the dead weight of the plate P is loaded on the vibration isolating material 1. , the recess 2A
It is desirable to determine the shape, fitting area, etc. of the convex portion 2B and the shape of the convex portion 2B based on the bonding strength determined in advance through experiments. In particular, as shown in FIG. It is preferable for safety to do so.

Incidentally, the concave portion 2A and the convex portion 2B in the present invention are as follows:
Although it is sufficient to form only one on each of the divided vibration isolating members 1A and 1B, a plurality of them is preferable from the viewpoint of bonding strength.
