Abstract

<P>PROBLEM TO BE SOLVED: To provide a partitioning and flooring structure which has a sound insulating performance equal to or more than before and is constructed easily. <P>SOLUTION: An integral underfloor space A is configured between adjacent living rooms 20, 22 by eliminating the installation of partition wall members 16 up to the lower side of floor substrate members 26, 28. Therefore, the amplification of resonance is prevented from increasing in a frequency band of 63 Hz which, in many cases, is determined as the frequency of sound level of impact on a heavy floor. Also, the floor substrate members 26, 28 are separated by the adjacent living rooms 20, 22 to prevent the noise from propagating between the adjacent rooms via the floor substrate members 26, 28 by installing the floor substrate members 26, 28 of a dry double floor on both sides of the substrate member 14 of a partition wall. In addition, the noise is reduced from propagating through the integral underfloor space A between the adjacent living rooms 20, 22 by inserting a sound absorber 36 from the lower side of the substrate member 14 of the partition wall to a range with a predetermined height. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a partition and floor construction method for an apartment house, etc., and a partition and a floor structure.

  In the apartment rooms in recent years, partition walls and floor structures that use a soundproof material such as gypsum board for the partition structure in combination with the dry double floor and have improved sound insulation are widely adopted. By the way, in the conventional dry double floor construction method, as described below, a construction method for constructing a partition prior to the construction of the double floor (referred to as “wall preceding construction method” in this description), There is a construction method (referred to as “floor advance construction method” in this description) that constructs a double floor prior to construction.

  Now, the partition and floor structure by a wall preceding construction method are the structures in which the partition wall 10 which partitions between living rooms is directly installed with respect to the floor slab 12, as shown to Fig.5 (a). Specifically, the partition wall 10 includes a partition wall base material 14 made of steel, wood, etc. and assembled in a frame shape between a floor slab 12 and a ceiling slab (not shown). On both sides of the base material 14, a partition wall material 16 and an underfloor partition wall material 18 made of gypsum board or the like are fixed. A plurality of support legs 24 are erected on the floor slab 12 at a predetermined interval, and by the support legs 24, the floor base material 26 of an independent dry double floor is provided in each of the adjacent living rooms 20 and 22. 28 is supported. The support legs 24 are usually made by fixing rubber legs to the lower part of a steel support, and the floor base materials 26 and 28 are made of particle board, plywood or the like. Then, on the floor base material 28, flooring, carpet, felt carpet, or the like is laid as the floor finishing material 30, and a skirting board 32 is fixed to the butt portion of the partition wall material 18 for the under floor with the floor finishing material 30. Has been.

  On the other hand, the partition and floor structure by the floor prior construction method is different from the wall prior construction method, as shown in FIG. 5 (b), the partition wall 10 for partitioning the living rooms is placed on the floor base material 28, and the floor base Between the material 26 and the floor slab 12, a support leg 34 corresponding to a heavy load for receiving the load of the partition wall 10 is installed (for example, Patent Document 1).

In addition, FIG. 6 illustrates and explains the wall preceding construction method. First, a concrete frame is placed (S100), piping and wiring in the dwelling unit are performed (S110), and the partition wall base material 14 is attached to the floor slab 12. It is installed on the top (S120). Subsequently, the partition wall material 18 for the under floor is attached to the partition wall base material 14 to a position usually higher than the floor base material 28 to be constructed later (S130), and the support legs 24 are installed on the floor slab 12, and the floor base The materials 26 and 28 are attached (S140). Thereafter, the partition wall material 16 is attached so as to be in close contact with the upper end of the floor partition wall material 18 (S150), and then the floor finishing material 30 is spread on the floor base material 28 (S160). Finally, a baseboard is attached to the partition wall material 18 for the under floor (S170), and the cloth is pasted so as to cover the partition wall material 16 and the partition wall material 18 for the floor (S180). Complete.

By the way, the partition and floor structure (Fig. 5 (a)) by the wall advance construction method is divided into the underfloor space A by the partition wall 10 and closed for each of the living rooms 20 and 22. In some cases, the pressure wave generated by the vibration of 30 is resonantly amplified in the underfloor space A, and the heavy floor impact sound level increases (the heavy floor impact sound blocking performance decreases). Here, the resonance amplification effect of the pressure wave (air spring) in the underfloor space A is caused by the underfloor space dimension, and is the underfloor space dimension in which resonance amplification occurs in the 63 Hz band, which is often the determination frequency of the heavy floor impact sound level. In the case of a certain under-floor space height H = 20 to 90 mm, the case of 50 to 120 mm corresponds to the floor finish height of a general dry double floor. Therefore, resonance amplification in the 63 Hz band occurs in partitions and floor structures using dry double floors in many apartment buildings. Especially, when partition and floor structures by the wall advance construction method are used for small living rooms, heavy floor impact There is a problem that the increase in sound level becomes remarkable.

Moreover, in order to enhance the sound insulation effect, it is necessary to construct the partition wall material 18 for the under floor also in the lower part of the door frame (the space between the floor slab 12 and the door frame). The construction of the partition wall material 18 for the floor under the place is naturally a difficult task. Further, in order to install piping such as gas and hot water and electric wiring in the space between the floor slab 12 and the floor base material 26, holes for piping and wiring are processed on the partition wall material 18 for the floor under construction. In addition, in order to enhance the sound insulation effect, it is necessary to close the gap between the hole, the piping, and the wiring with a sealing material.

On the other hand, the partition and floor structure according to the floor prior method (FIG. 5 (b)), the underfloor space A is without being divided by the partition wall 10, and constitutes an integral space under the floor of an adjacent room 20 and 22. Therefore, the pressure wave spreads across the floor in the underfloor space A, and the heavy floor impact sound blocking performance is less likely to decrease due to the resonance amplification of the pressure wave in the underfloor space A. However, since the floor base materials 26 and 28 of the adjacent living rooms 20 and 22 are shared, there is a problem that solid sound generated when the door is closed or walking is easily transmitted between the adjacent living rooms 20 and 22. is there. Further, since the partition wall 10 does not reach the floor slab 12, there is a possibility that the sound insulation performance between the adjacent living rooms 20 and 22 may be lowered, and it is necessary to take measures for sound insulation therefor.

  The present invention has been made in view of the above problems, and the object of the present invention is to have a sound insulation performance equivalent to or higher than that of the partition and floor structure by the conventional wall preceding construction method or floor preceding construction method, and the construction is performed. An object of the present invention is to provide an easy partition and floor construction method and a partition and floor structure.

As shown in FIG. 1, the partition and floor structure according to the embodiment of the present invention has a floor base of a dry double floor on both sides of the base material 14 of the partition wall assembled in a frame shape on the floor slab 12. The materials 26 and 28 are respectively constructed. Therefore, the sound absorbing material 36 is inserted to a predetermined height in the space surrounded by the base material 14 of the partition wall. As the sound absorbing material 36, a flexible sound absorbing material such as glass wool or rock wool is usually stacked up to a position higher than the floor finishing material 30, but the stacked height is adjusted according to the required sound insulation performance. For example, 32 kg / m ³ of glass wool is applied with a thickness of 50 mm and a stacked height of 200 mm. And the partition wall material 16 is attached to the upper part rather than the floor base materials 26 and 28 of the both sides of the base material 14 of a partition wall. For example, the partition wall material 16 is generally a single gypsum board with a thickness of 12.5 mm, but a gypsum board with a thickness of 9.5 mm or 15 mm is also used as necessary. Further, a plurality of sheets may be overlapped on one side, and a plywood board or a so-called calcium board may be used instead of the gypsum board. In addition, about the support leg 24, the floor base materials 26 and 28, and the floor finishing material 30, it is also possible to use the systemized product suitably.

And after the construction of the partition wall material 16, the floor finishing material 30, the baseboard 32, and the cloth are constructed. In the illustrated example, a fin-like closing material 32 a having a thickness of about 2 to 3 mm protrudes from the lower part of the base board 32, and the gap between the base board 32 and the floor finishing material 30 is closed by this closing material 32 a.

After installing (S120), it replaces with the process (S130) of attaching the partition wall material 18 for under floors to the partition wall base material 14 to a position higher than the floor base material 28 to be constructed later, the lower part of the partition wall base material 14 The sound absorbing material 36 is inserted into the gap (S300).
In addition, the door part is also attached to the gap at the lower part of the door reinforcement frame in place of the step (S210) of attaching the door frame / pallet (see FIG. 2) and then attaching the gypsum board to the lower part of the door reinforcement frame (S210). The sound absorbing material 36 is inserted (S310).

Can be prevented. Also, by installing floor double base materials 26, 28 on both sides of the base material 14 of the partition wall, the floor base materials 26, 28 are separated in the adjacent living rooms 20, 22, and the floor base material 26, This is to prevent the propagation of noise between adjacent rooms via 28. Further, by inserting the sound absorbing material 36 from below the base material 14 of the partition wall to a predetermined height range, it is possible to reduce the propagation of noise between the adjacent living rooms 20 and 22 through the integrated underfloor space A. it can.

And after the construction of the partition wall material, the finishing of the partition and the floor is completed by performing at least one construction of the floor finishing material 30, the baseboard 32, and the cloth (not shown).
For the installation portion of the door 46, a door frame (door reinforcement frame) 40, a door frame 42, and a door frame (pallet) 44 are assembled on the floor slab 12 via a plurality of door reinforcement bundles 38. By inserting the sound absorbing material 36 into the space surrounded by the floor slab 12, the door reinforcing bundle 38, and the door frame 40 , the construction of the partition wall material 16 up to the lower side of the floor base materials 26 and 28 is omitted. . Thereby, an integrated underfloor space is formed between the adjacent living rooms 20 and 22 with respect to the door installation portion. Therefore, the overall construction work of the partition wall material 16 is facilitated, and an increase in resonance amplification in the 63 Hz band, which often becomes the determining frequency of the heavy floor impact sound level, is prevented. Further, by inserting the sound absorbing material 36 below the door reinforcing frame 40, it is possible to reduce the propagation of noise through the underfloor space A between the adjacent rooms 20 and 22.
