Description

  The present invention relates to a floor structure and a construction method thereof.

As a floor structure in each dwelling unit of a conventional apartment house, a so-called double floor is constructed. In the case of partitioning in the double floor structure 21 in this single dwelling unit, as shown in FIG. 11, after the partition wall 22 is made first, the floor base material 23 is continuously spread to construct a double floor. It was. However, the floor structure 21 cannot freely change the partition wall 22 according to the family structure and the like. Therefore, a method of creating the partition wall 22 after constructing the floor first, instead of preceding the wall as described above, can be considered. Moreover, as another floor structure, there exists invention of Unexamined-Japanese-Patent No. 2004-44093, for example.
JP 2004-44093 A

  However, if the floor structure 21 is constructed in advance of the floor, it is necessary to reinforce the floor base material 23 where the partition wall 22 is made, and therefore the partition wall 22 cannot be freely changed without any restrictions. It was. Further, since the floor structure 21 has a large space 24 formed below the floor base material 23, there is a problem that sounds of adjacent rooms 25 partitioned by the partition wall 22 can be heard through the space 24. It was.

  The present invention has been made in view of these problems, and the purpose of the present invention is to freely change the partition wall as needed even if the floor is constructed first, and between adjacent rooms separated by the partition wall. It is to provide a floor structure in which no sound can be heard and a construction method thereof.

In the floor structure for solving the above problems, a number of non-land surface adjusting materials are installed on the upper surface of the concrete slab, and a number of floor base materials made of thermoplastic foam resin are in close contact with the non-land surface adjusting material. paved, have become dense solid in uneven surface adjustment member between the floor base member and the concrete slab is deformed to flat, partition wall is provided in any portion of the upper surface Harikon they finish the floor base member In addition, an uneven surface adjusting material is installed on the upper surface of the concrete slab via an additional striking layer, and a lower portion of the uneven surface adjusting material is buried in the striking layer.

  By installing a floor base material that is closely packed through a number of unevenness adjusting materials, vibration energy of heavy floor impact sound can be effectively absorbed. In addition, since the lower part of the floor base material is made solid by the flatness-imparting material deformed flat, it is possible to completely block the noise of adjacent rooms separated by the partition walls. In addition, since the lower part of the floor base material has become solid with a flattened unevenness-adjusting material, the partition wall can be received with an evenly distributed load, and the partition wall can be freely adjusted according to the family structure etc. Can be changed to In addition, because the slab thickness is increased by the additional striking layer provided under the non-land surface adjusting material, the vibration energy of the heavy floor impact sound and the light floor impact sound can be absorbed effectively, and the so-called drum phenomenon is called resonance. The phenomenon can also be prevented. In addition, since the lower part of the unevenness adjusting material is buried in the striking layer, integration with the concrete slab is facilitated, and unevenness adjustment can be easily performed. In addition, the floor leading allows the adoption of a free plan for partitioning. In addition, the level adjustment can be easily and accurately performed by installing the floor base material via the additional striking layer having fluidity and the unevenness adjusting material.

Embodiments of the floor structure of the present invention will be described below with reference to the drawings. In the embodiments, the same components are described with the same reference numerals, and only different components are described with different reference numerals.

  FIG. 1 shows a floor structure 1 according to a first embodiment. This floor structure 1 is in each dwelling unit (one dwelling unit) 2 of an apartment house, and a floor base material 5 is closely laid on an uneven surface adjusting material 4 installed on the upper surface of a concrete slab 3, A partition wall 7 is built on a finishing material 6 stretched on the upper surface of the floor base material 5.

  The floor base material 5 is a thermoplastic foamed resin composite, and includes a lower member 8 made of a foamed resin such as a polystyrene-based resin, a polyolefin-based resin, and a urethane resin, and a hard thermoplastic foam installed on the upper surface of the lower member 8. It is composed of a resin pier 9, and a finishing material 6 is nailed to the pier 9 by nailing or the like.

  Further, the unevenness adjusting material 4 is a mortar, and a plurality of dumplings provided at appropriate intervals are flattened by the floor base material 5 so as to be dense with the concrete slab 3. Therefore, since the floor base material 5 receives the partition wall 7 with an equal distribution weight, the partition wall 7 can be built in an arbitrary place, and even after the partition wall 7 is built, as needed. It can be changed freely without any restrictions.

  Moreover, FIG. 2 is the floor structure 10 of 2nd Embodiment. This floor structure 10 is provided with a scraping material 11 such as a particle board on the lower side of the finishing material 6, and the other structure is the same as that of the floor structure 1 of the first embodiment. Thus, when the disposing material 11 is provided on the lower side of the finishing material 6, the base material that supports the partition wall 7 can be strengthened, and the floor base material 5 is used as a scaffold for other interior work before the finishing material 6 is applied. Therefore, work efficiency can be improved.

  FIG. 3 shows a floor structure 12 according to the third embodiment. This floor structure 12 is formed by integrally forming the scraping material 11 on the floor base material 5 and has the same configuration as the floor structure 1 of the first embodiment except for this. This is formed by integrally forming a scraping material 11 such as a particle board in place of the crosspiece 9 on the upper surface of the lower member 8 which is a thermoplastic foamed resin composite. When the scraping material 11 is integrally formed with the floor base material 5 in this manner, the floor base material 5 can be used as a scaffold for other interior construction work before the finishing material 6 is stretched.

It is formed by closing with a bottom plate 15. FIG. 6 shows the floor structure 1 in which the floor base material 5 is formed with a planar lattice-shaped hollow portion 16. When the gap 13 or the hollow portions 14 and 16 are formed in this way, the vibration energy of the light floor impact sound of the floor can be absorbed, so that the sound insulation of the floor can be improved.

  The bottom plate 15 is made of an elastic closed-cell thermoplastic foamed resin. Examples of the thermoplastic foamed resin include high-density polyethylene, linear low-density polyethylene, polypropylene, propylene / ethylene copolymer, and styrene / polyethylene copolymer. A foamed product having a density of 8 to 40 g / l is used.

  The configuration in which the gap portion 13 or the hollow portions 14 and 16 are provided can also be applied to the floor base material 5 in the floor structures 10 and 12 of the second and third embodiments. FIG. 7 illustrates the third embodiment.

When the scraping material 11 is integrally formed with the floor base material 5 in this way, the floor base material 5 can be used as a scaffold for other interior construction work before the finishing material 6 is stretched. Since the vibration energy of the light floor impact sound of the floor can be absorbed, the sound insulation of the floor can be enhanced.

  FIG. 8 shows a floor structure 17 according to the fourth embodiment. This floor structure 17 is obtained by forming a striking layer 18 having an appropriate thickness on the upper surface of the concrete slab 3 with a mortar or the like, and installing the unevenness adjusting material 4 thereon. It is the same structure as the floor structure 1 of 1 embodiment. A lower portion of the flat unevenness adjusting material 4 is buried and integrated with the additional striking layer 18, and level adjustment and unevenness adjustment are performed by this embedding. Further, by forming the slab thickness integrally with the additional striking layer 18 and the unevenness adjusting material 4, the influence of the heavy floor impact sound and the lightweight floor impact sound can be reduced.

  In addition, the structure which forms the additional striking layer 18 of thickness suitably on the upper surface of this concrete slab 3 is the floor structure 10, 12, 17 of said 2nd-4th embodiment, and FIGS. 4-7. The present invention can also be applied to the floor structure 1.

  Next, a method for constructing the floor structure will be described. FIG. 9 shows a floor structure construction method according to the first embodiment.

Next, when the floor base material 5 is pushed downward with the upper surface of the joist 19 set as a reference line when installed in the inner periphery of the room, the unevenness adjusting material 4 is flattened flatly to close the space between the concrete slab 3. As a matter of fact, the lower part of the unevenness adjusting material 4 is buried in the striking layer 3 to be integrated. The floor base material 5 of the 1st row is installed by such a method.

  Next, after installing the first-floor floor base material 5, as shown in (2) of the same figure, the unevenness adjusting material 4 is installed in the location which installs the second-row floor base material. And while installing the floor base material 5 by the same method as the above, the floor base material 5 is closely spread over the whole surface of the concrete slab 3 by repeating this process sequentially. Next, as shown in FIG. 1, a finishing material 6 is pasted on the floor base material 5, and a partition wall 7 is built in an arbitrary portion of the finishing material 6 to construct the floor structure 1.

  In addition, although the floor base material 5 was installed 1 row at a time, it is not restricted to this, It can install in multiple rows, such as 2 rows or 3 rows. Further, the floor base material 5 can be installed one by one instead of in units of rows.

  FIG. 10 shows a floor structure construction method according to the second embodiment. First, as shown in (1) of FIG. 7, an adhesive such as a primer is applied to the upper surface of the concrete slab 3, and then a mortar with an appropriate thickness is applied thereon to form the striking layer 18. For example, the additional striking layer 18 is formed only at a location where the floor base material 5 in the first row is installed.

  Next, before the additional striking layer 18 is dried, a large number of mortar dumpling-like unevenness adjusting materials 4 are installed thereon, and the floor base material 5 is installed thereon. Then, when the floor base material 5 is pushed downward with the upper surface of the joist 19 as the reference line when installed in the inner periphery of the room, the unevenness adjusting material 4 is crushed flatly and densely between the concrete slab 3. At the same time, the lower part of the unevenness adjusting material 4 is buried in the striking layer 18 to be integrated.

  Next, after the first row of the floor base material 5 is installed, mortar is applied to the place where the second row of the floor base material is installed to form the second row of striking layers 18. Next, the floor base material 5 is installed by the same method as described above, and the floor base material 5 is closely spread over the entire surface of the concrete slab 3 by sequentially repeating this process. Next, as shown in FIG. 8, a finishing material 6 is stuck on the floor base material 5, and a partition wall 7 is built in an arbitrary portion of the finishing material 6 to construct a floor structure 17.

  In addition, although the floor base material 5 was installed one row at a time, the present invention is not limited to this, and a plurality of rows such as two rows or three rows can be installed and the striking layer 18 can be formed in a range of the plurality of rows. it can. Further, the floor base material 5 can be installed one by one instead of in units of rows, and the additional striking layer 18 can be formed at a place where the floor base material 5 is installed one by one.

  By sequentially repeating this process, the floor base material 5 can be easily spread, and the unevenness and the level can be easily adjusted, so that the floor structure 17 can be easily constructed.
