Description

  The present invention relates to a sound insulation floor construction method.

  A plurality of joist-like vibration isolating members are prepared by holding an impact absorbing material in an elongated joist-like holding material so as to be arranged at a predetermined interval in the length direction. Install the anti-vibration member on the basement floor with the shock-absorbing material facing down, and place the floor plate over the upper surface of the joist-like anti-vibration retaining material after placing it in parallel. A construction method for forming a sound insulation floor in such a manner is conventionally known.

According to this method, after installing the shock absorbers on the basement floor surface one by one so as to be in a predetermined distributed arrangement state in the horizontal two-dimensional direction, the floor board is installed thereon. Construction can be facilitated compared to construction.

  However, in the construction method as described above, since the holding member of each vibration isolating member has an elongated joist shape, each shock absorbing material cannot be stably installed on the basement floor surface. There is a problem that the absorbent material easily falls with the holding material.

  In addition, the shock absorbing material must be installed on the basement floor so as to be in a predetermined dispersed arrangement state in the horizontal two-dimensional direction, and for this reason, each joist-like vibration isolating member, as described above, Although it must be installed so as to be in a parallel state at predetermined intervals, there is also a problem that the work requires labor.

  In view of the above problems, the present invention can efficiently install the shock absorbing material on the basement floor surface, and can stably install each shock absorbing material, It is another object of the present invention to provide a method for constructing a sound insulating floor that can easily install each shock absorbing material at a predetermined position in a two-dimensional direction along the surface of the base floor.

  The above-described problem is solved by using a panel-shaped vibration-proof member in which a shock-absorbing material is arranged and held on one surface portion of a holding plate so as to be in a predetermined dispersed state in a two-dimensional direction along the surface. The vibration member is installed on the basement floor surface with the shock absorbing material facing down, and then the floor plate is installed on the holding plate of the panel-shaped vibration isolation member. (First invention).

  In this method, it is possible to efficiently install the shock absorbing material on the base floor by using the panel-shaped vibration isolating member.

  Moreover, in the panel-shaped vibration-proof member, the shock-absorbing material is arranged and held on one surface portion of the holding plate so as to be in a predetermined dispersed state in a two-dimensional direction along the surface. By installing the member on the floor of the base, it can be installed stably, and even if it hits, it will not fall with the holding plate.

  In the first invention, a plurality of the panel-shaped vibration-proof members are provided, and the panel-shaped vibration-proof members may be installed on the base floor surface with the holding plates in contact with each other (second invention). ).

  In this case, when the holding plates are positioned to each other, each shock absorbing material can be easily installed at a predetermined position in the two-dimensional direction along the surface on the base floor surface.

  Since the construction method of the sound insulation floor according to the present invention is as described above, it is possible to efficiently install the shock absorbing material on the basement floor surface, and to install each shock absorbing material stably. In addition, each shock absorber can be easily installed at a predetermined position in the two-dimensional direction along the surface on the base floor surface.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  The sound insulation floor of the embodiment shown in FIGS. 1 to 5 is a case where a sound insulation floor is formed on a base floor 2 formed on a steel floor beam 1 on the floor of a building. As shown in FIG. 1, the ALC dropped between the floor beams 1... Is placed so that the lower surface is located below the upper surface of the floor beam 1 and the upper surface is located above the upper surface of the floor beam 1. It consists of what was comprised using the board 3, and construction of a sound-insulating floor is performed using the several panel-shaped vibration isolator 4 ....

  As shown in FIGS. 2 (A-1) and (A-2), each panel-shaped vibration-proof member 4 has a length dimension A and B of 1 to 2 when one module is 900 to 1000 mm. A holding plate 5 composed of a square or rectangular square plate of the module is provided, and shock absorbers 6 are provided on one surface of the holding plate 5 in a direction in which one side extends and a direction in which the other side extends. A plurality of units are held in a distributed arrangement state at intervals of a and b of ½ module or less.

  In addition, there is no restriction | limiting in the form of each impact-absorbing material 6, You may consist of a vibration isolating rubber, a metal spring, or what combined them. Further, as shown in FIGS. 2 (B-1), (B-2) and FIG. 3, the panel-like vibration isolator 4 disposed on the outer wall side or under the partition has a hard rubber 7 for preventing sinking. It is attached.

  The construction uses a plurality of the above-mentioned panel-shaped vibration-proof members 4, and each panel-shaped vibration-proof member 4 is placed on the base floor 2 with the shock absorbers 6 facing down as shown in FIGS. 1 and 3. Then, the holding plates 5 are placed so as to be in contact with each other, and then, as shown in FIG. 4, a floor plate 8 made of plywood or the like is placed on the holding plates 5 of the panel-like vibration-proof members 4. This is done by installing it.

  In the sound insulation floor formed in this way, as shown in FIG. 5, the baseboard 10 installed at the boundary between the floor board 8 and the interior board 9 allows air between the base floor surface 2 and the holding board 5 to flow. It is made of vent skirting so that it can be pulled out indoors.

  According to the construction method described above, the use of the panel-shaped vibration-proof members 4... Enables not only the installation of the shock absorbers 6 to the base floor 2 efficiently but also the panel-shaped vibration-proof members. In the member 4, the shock absorbers 6... Are held on one surface portion of the holding plate 5 in a distributed state in a two-dimensional direction along the surface. 2 can be installed stably, and even if it hits, it does not fall with the holding plate 5.

  Moreover, the installation of the panel-shaped vibration isolating members 4 on the base floor 2 is performed in a state where the holding plates 5 are in contact with each other, so that the holding plates 5 are positioned with each other. Thus, each of the shock absorbers 6 can be easily installed on the base floor 2 at predetermined positions in the horizontal two-dimensional direction.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the sound insulation floor is formed on the base floor 2 formed using the ALC plate 3 on the floor beam 1 on the floor of the building has been described. It is also possible to form on the surface.

The construction method of embodiment is shown, and it is a cross-sectional front view which shows the process of installing a panel-shaped vibration-proof member on a basement floor surface. Fig. (A-1) is a front view of a panel-shaped vibration-proof member, Fig. (B-2) is a bottom view of the same, and Fig. (B-1) is a front view of another panel-type vibration-proof member. ) Is a bottom view of the same. It is a top view which shows the installation state of a panel-shaped vibration-proof member. It is a cross-sectional front view which shows the installation state of a panel-shaped vibration-proof member, and the process of installing a floor board on the holding plate of a panel-shaped vibration-proof member.
