Description

  The present invention relates to a building structure provided between a foundation floor and a ceiling of a building and a construction method for building the building structure.

In recent years, the floor structure of a building may be a double floor.
There are two methods for building a building structure having a double floor: a wall advance method and a floor advance method.
In the wall advance construction method, after constructing the partition wall, a double floor is constructed for each floor of the indoor space.
In the floor prior construction method, a partition wall is constructed after constructing a double floor forming a floor of a plurality of indoor spaces.
The double floor is provided with a gap having a predetermined height between the support leg and the upper surface of the foundation floor.
The support leg has a rubber bush or the like at a location in contact with the foundation floor.
The rubber bush has a function capable of suppressing the vibration generated in the double floor from being transmitted to the base floor.
This form of acoustic propagation is called acoustic propagation by solid state propagation.
The rubber bush is compressed by the weight of furniture or the like placed on the double floor, and the support leg is slightly contracted according to the weight.
The prior wall construction method is a conventional construction method, in which floor construction has to be performed in a narrow indoor space, and it is difficult to change the installation position of the partition wall after construction once.
Thus, establishment of a floor advance construction method has been desired.

Toilet, unit bath, etc. are installed in the indoor space of the building.
In the floor advance method, the lower end of the partition wall is fixed to the upper surface of the double floor.
In the indoor space for storing the unit bath, the unit bath is installed directly on the foundation floor without providing a double floor due to the arrangement of water pipes and the like.
Therefore, a notch hole having a contour surrounding an indoor space for storing a storage device such as a unit bath is provided in the floor panel constituting the two-entry floor.
For this reason, the indoor space provided with the unit bath communicates with the underfloor space sandwiched between the double floor and the foundation floor of the adjacent indoor space.
In the indoor space for storing the toilet, a drainage piping system is provided in the gap between the double floor and the foundation floor.
Therefore, the gap between the double floor and the foundation floor in the indoor space for storing the toilet communicates with the gap between the double floor and the foundation floor in the adjacent indoor space.
This form of acoustic propagation is called acoustic propagation by air propagation.
For this reason, for example, when a bathtub is dropped in the unit bath, the wall of the unit bath emits noise, and the radiated sound waves wrap around the gap between the double floor and the foundation floor due to air propagation. A phenomenon of acoustic radiation in space occurs.
In addition, a phenomenon occurs in which sound generated from the drainage piping system when using the toilet wraps around the gap between the double floor and the foundation floor in the adjacent indoor space and propagates into the adjacent indoor space.
In order to prevent this phenomenon, it is conceivable to seal the gap between the floor panel and the foundation floor along the contour or partition wall surrounding the indoor space as viewed from above.
If the padding is packed in the gap between the floor panel and the foundation floor along the contour or partition wall that surrounds the indoor space, if the padding density is low, the sound waves generated in the storage space propagate to the indoor space without being blocked. On the other hand, if the density of the padding is high, the movement of the support legs is suppressed and the solid is propagated from the double floor to the foundation floor through the support legs.

  Since the building structure construction method according to the sixth to eighth embodiments of the present invention is the same as the procedure of the building structure examination method according to the first embodiment, the description thereof will be omitted.

Moreover, the building structure which concerns on embodiment of this invention, and the construction method of the building structure have the following effects by the structure.
A gap having a predetermined height S is provided between the floor panel 11 and the base floor L supported by the support legs 20, and the floor panel 11 and the ceiling 50 are partitioned by a partition wall 30. The projection 13 projecting toward the floor L and the sealing mat member 42 seal the space between the foundation floor 6 and the floor panel 11, and the side G of the projection 13 connects the sealing mat member 42 to the partition wall 30. Since the sound generated in the indoor space is suppressed from being propagated to the gap between the adjacent double floor 10 and the foundation floor 6, the sound generated by the support legs 20 on the double floor 10 is further suppressed. It does not interfere with the suppression of solid propagation to the foundation floor 6.
Further, a gap having a predetermined height S is provided between the floor panel 11 supported by the support legs 20 and the foundation floor surface L, and the partition between the floor panel 11 and the ceiling 50 is partitioned by the partition wall 30, and the foundation floor 6. The projection 7 projecting from the floor panel 11 to the floor panel 11 and the sealing mat member 42 laid on the lower surface of the floor panel 11 seal between the foundation floor 6 and the floor panel 11, and the projection 7 is the sealing mat. Since the member 42 is crushed along the partition wall 30, the sound generated in the indoor space H is restrained from propagating to the gap between the adjacent double floor 10 and the foundation floor 6, and the support legs 20 are separated from each other. It does not interfere with the suppression of the sound generated on the heavy floor 10 from solid propagation to the foundation floor 6.
In addition, a gap having a predetermined height S is provided between the floor panel 11 and the foundation floor L supported by the support legs 20, and the floor panel 11 and the ceiling 50 are partitioned by a partition wall 30 and arranged vertically. The sealing member 41 and the sealing mat member 42 are sealed between the foundation floor 6 and the floor panel 11 so that the sealing member 41 crushes the sealing mat member 42 along the partition wall 30. Therefore, the sound generated in the indoor space H is suppressed from propagating through the air to the gap, and the support leg 20 is not disturbed from suppressing the sound generated in the double floor 10 from being solid-propagated to the foundation floor 6.
Further, the sealing mat member 42 has a pair of free state regions W2 at positions sandwiching the crushing region W1 of the entire region W of the surface to be crushed, and at least one of the free state regions W2 has a width dimension at the end. Since the dimensions are such that the thickness in the state can be substantially maintained, the sound generated in the indoor space passes through the place where the sound is generated from one end portion sandwiching the crushing region of the sealing mat member 42 and the other. It is greatly attenuated in the process of air propagation to the end of the sound, and acoustic air propagation can be efficiently suppressed.
Further, the floor panel 11 constituting the double floor 10 is provided with a notch hole having a contour R surrounding the indoor space for housing the unit bath storage device, and the side G above the sealing member 41 is disposed on the floor panel 11. Therefore, the sound emitted from the storage device can be prevented from propagating from the indoor space H to the gap under the double floor.
Further, since the longitudinal elastic modulus of the portion where the sealing mat member 42 is crushed is made smaller than the longitudinal elastic modulus of the pedestal 24 of the first support leg 20a, the function of suppressing the acoustic solid propagation of the first support leg 20a is obstructed. do not do.

Further, when the bus unit is housed in one indoor space H, it is possible to suppress the sound generated from the bus unit from propagating from the indoor space H to the gap between the double floor 10 and the foundation floor 6 in the adjacent indoor space H. Further, since the base 24 of the support leg 20 can freely expand and contract, solid propagation from the double floor 10 to the foundation floor 6 or fixed propagation from the foundation floor 6 to the double floor 10 can be suppressed.
In addition, when a toilet unit is placed in one indoor space H, the sound generated from the water distribution pipe system of the toilet unit passes through the gap between the double floor 10 and the basic floor 6 of the indoor space, and the double floor of the adjacent indoor space H Propagation of air to the gap between 10 and the foundation floor 6 can be suppressed. Further, since the base 24 of the support leg 20 can freely expand and contract, solid propagation from the double floor 10 to the foundation floor 6 or fixed propagation from the foundation floor 6 to the double floor 10 can be suppressed.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
The joist 43 and the sealing member 41 are separate members, but may be integrated.
Moreover, although the sealing member 41 is fixed via the joist 43, the sealing member 41 may be directly fixed.
Further, one or both of the front surface and the back surface of the sealing member 41 may be covered with a sealing mat member.
