Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a hollow double wall and a jig used therein.

In recent years, in collective buildings such as hotels, apartment complexes, hospitals, and schools, the sound insulation properties of internal partition walls have become important from the standpoint of protecting privacy and improving livability. There is. Because of this, the voices of people talking in the next room, the piano, etc.
It became necessary to use partition walls to block noise from stereos, televisions, toilets, etc., and the Ministry of Construction is providing guidance by establishing standards for sound insulation. (Table 1) Table 1 Effective sound insulation 14j specified by the Ministry of Construction - In other words, for the partition walls of the above buildings, the sound insulation standards must be 14j or higher.
What is needed is something that will do the trick. On the other hand, as buildings become taller, there is a growing demand for lighter buildings themselves, and it is necessary to reduce the weight of partition walls as well as fire resistance.

In general, N-acoustic materials are materials that do not transmit much energy, but since the transmission loss of heavy water depends on the product of the weight per area of the material and the frequency, it is difficult to say whether heavy materials are good or not. rules). Therefore, reducing the weight of wall materials and improving sound insulation performance are contradictory.

Regarding sound insulation properties, there is a phenomenon called the coincidence effect, in which the wall resonates at a certain noise frequency, and at that frequency it exhibits a much smaller sound insulation property than the value predicted by the mass law. There is a phenomenon, and in order to prevent this coincidence effect, it is effective to construct a so-called hollow double wall by configuring multiple sound insulating boards of wide thickness and different materials with space or sound absorbing material in between. . In addition, this hollow double wall has advantages such as not only sound insulation but also ease of wiring work, so it is quite commonly used in buildings.

The basic construction methods for constructing this hollow double wall include using studs, using gypsum adhesive, and creating two independent walls and using them as one wall. There is.

However, when using studs, the studs are integrally fixed to the wall structure and surface material, so
There is a disadvantage that sound propagates through the studs, making it impossible to obtain the original sound insulation performance.Also, the method of using gypsum adhesive requires applying gypsum adhesive on both sides of the wall structure in the form of balls. Because the rolled object is placed and fixed with adhesive by pressing the finishing plate against it, a sound bridge (sound bridge) may occur due to the adhesive, and the plaster-based adhesive is an adhesive that uses water, so it may not adhere to the finished material surface. They had many drawbacks, such as the tendency for mold to grow, the inability to fit insulation materials, air intake materials, etc. into the hollow parts, the difficulty in replacing wall finishing materials, and the inability to create large air spaces. Furthermore, the method of making two independent walls and using them as one wall has the disadvantage that the overall wall thickness increases since two good walls are made on the negative side, resulting in a large loss in terms of effective use of space. was.

The present invention has been made as a result of intensive research to eliminate the above-mentioned drawbacks.

Hereinafter, the present invention will be explained based on the drawings. The hollow double wall construction jig of the present invention is composed of a female screw plate (A), a male screw plate 1-(B), and a female screw plate h.
As shown in Fig. 1, (A) has a cylindrical receiver (2) protruding from the center of one side of the fixed plate (1), and a female thread (3) on the inner peripheral surface of the cylindrical receiver (2). ) is engraved and this fixed plate (1
) has a plurality of locking claws (4) with sharp tips (31) installed on the other side of the wooden protrusion. This female screw plate (Δ) is made of metal, and the size of the fixing plate (1) is 2CIIl. ×2CIl
1~10cIIl x 10cm', and a cylindrical receiver (2
) has a length of about 2 to 1Q cm and an inner diameter of 0.5 to 2.0 cm.
It is approximately mφ. j: The length of the locking claw (4) is 1.
5-2,0 CI 11th place, with 4 punched and foldable ones in the four corners. The -I screw plate (A) is provided with a locking claw (4), which makes it easy to attach the jig to the wall (q).
The female screw plate (Δ) can be locked to the wall structure by simply driving the locking claw (4) with a hammer, etc., without requiring any other parts such as wood screws, bolts, or adhesives.・Can be fixed. Next, as shown in Fig. 2, the male screw plays 1 to (b) have a rod-shaped body (6) protruding from the center of one side of the take-out plate (5), and the outer peripheral surface of the rod-shaped body (6). In addition to the male screws (7) being engraved, a vibration isolating material (8) is provided on the other surface of the mounting plate (5) via an adhesive. This male screw plate (
The material B) is not limited to metal, but may also be made of nylon, ABS, acetal resin, or other high-synthesis and high-strength plastic deck. In addition, the size of the plate surface, that is, the plate (5), is approximately the same as the fixing plate (1) of the female screw plate (A). Urethane foam, etc. is used, and it is formed to be approximately the same size as the take-out plate (5), and then adhesive and
It is fixed to the mounting plate (5) using adhesive tape or the like. The jig for constructing a hollow motorcycle wall of the present invention is constituted by the female screw plates 1 to (A) and the male screw plate (B) as described above.
The rod-shaped body (6) of the screw plate (B) is screwed onto the cylindrical receiver (2) of A) to be used as one body.

Continued on next page Next, a method for actually constructing a hollow double wall using the hollow double wall Wi construction jig of the present invention will be explained with reference to the drawings. First, as shown in Fig. 3, a wall unit (C) such as a foamed gypsum board is built between the upper beam (F) and the floor frame (G), and the wall frame (C) has a C on the top. Fix the shaped steel (10) and the L-shaped steel (11) at the bottom, respectively, and use the marking method etc. to determine the position where the 14 screw plate (A>) will be locked on the side of the rear wall frame (C). Drive the locking claw (4) of the female screw plate 1-(Δ) into that position with a hammer, etc. and fix the female screw plate (A) with lυ. is 300
A range of ~6QQmm is appropriate. Next, screw the rod-shaped body (6) of the Ijt screw plate (B) into the cylindrical receiver (2) of the female screw plate 1 to (A) to connect the female screw plate 1 to (A) and the male screw plate (B). stick together. At this time, one of the important steps is to make the height from the surface of the wall body (C) to the surface of the vibration isolator (8) bonded to the male screw plate (B) constant. If the heights are uneven, the adhesion of the wall surface finishing material will not be uniform, causing partial lifting or warping, and in extreme cases, peeling. Therefore, it is necessary to accurately equalize the height using a ruler or the like. In addition, the height from the surface of the wall skeleton (C) to the surface of the vibration isolator (8), that is, the wall skeleton (C)
The distance between the wall finishing material (D) and the wall finishing material (D) should be set arbitrarily based on the sound insulation design, but a range of approximately 20 to 50 mm is appropriate. Adhesive (9) is applied to the surface of the damping material (8) whose height is set uniformly as described above, and the wall surface finish (Δ(1)) is adhesively fixed.

As the adhesive (9) in this case, commonly used adhesives such as rubber, epoxy, and polyurethane adhesives can be used, but rather than poxy adhesives, rubbery elastic adhesives such as polyurethane or rubber adhesives The right glue is more suitable. In addition, adhesives called elastic sealants such as butyl rubber, silicone, or thiokol are also suitable adhesives for implementing the present invention. Any method of applying the adhesive may be used, such as brushing, Ll-color coating, or extrusion coating using a caulking gun. Apply the adhesive in this way and install the wall finish 1, 1 (D) whose dimensions have been determined in advance.In this case, with the patch plate in contact with the finish material, Lighter 1]
It is even better to provide a phase to promote adhesion of the adhesive. Wall light l-
Finishing materials such as decorative gypsum board, decorative plywood, and slate board can be used as the material (one material), and wall base materials for decoration by pasting wallpaper or the like may also be used.

Furthermore, as shown in Fig. 5, after the wall finishing I, 1(D) is installed, finishing material (D) is applied to the upper and lower ends.
) L-1um (14) so as to straddle the joint (13)
Fix it with. The difference in level between the finishing material (D) and the base can be easily corrected by slight displacement of the vibration isolating material and adhesive. Additionally, as shown in Figure 4 (1), it is also possible to fill the space between the jigs with soundproofing material (E) or heat insulating material such as glass wool or rock wool before installing the wall finishing material (D). It is. (Continued on next page) Note that the hollow double wall construction jig of the present invention is
It is also possible to use a suction cup structure instead of the claw, but
This method is not necessarily effective when a non-woven fabric is stretched over the wall surface or when the surface is 111-sided, such as a foamed concrete board. Further, instead of the adhesive (9) applied on the vibration isolating material (8), it is optional to use a male screw plate using a vibration isolating agent having a pressure-sensitive adhesive layer in advance.

Although the hollow double wall constructed in this way has a thinner wall thickness than that of the conventional structure, it has significantly superior transmission loss (dB) at each frequency level ( Table 2) In the case of conventional construction methods, the wall frame and finishing material were made of rigid materials or rigid structures to form a double wall, resulting in noise leakage (i.e. sound bridge). This is because the sound insulation effect could not be expected much even if the wall thickness was made as thick as 110 to 131 mm.In the case of the construction method using the jig of the present invention, such
Since the occurrence of undulating creases can be eliminated by the combined use of a vibration damping agent and a rubber elastic adhesive, the wall thickness is 971, but the performance is not inferior to, or even exceeds, that of the comparative example.

As described above, according to the present invention, (1) the male screw plate is attached to the wall member by driving it into position with a hammer;

■Screw the male screw plate onto the female screw plate and adjust it to the desired height by rotating the screw. ■Apply adhesive on the vibration isolating material of the male screw plate. ■Install wall finishing materials. Not only is it possible to construct a hollow double wall with a simple process procedure, but it also provides the same or better sound insulation effect than conventional methods and saves space without increasing the thickness of the wall. It is possible. Furthermore, an existing single wall can be easily converted into a hollow double wall. Moreover, the jig for constructing a hollow double wall of the present invention is composed of a female screw plate 1 and a Mi wood screw plate, which have an extremely simple structure, so it is easy to manufacture and can be supplied at a low cost. obtain.

Therefore, the present invention can achieve the objectives of item 113.
