Description

  The present invention relates to a floor structure without floor noise.

  Conventionally, various floor structures, such as large pulls, joists, floor boards, and foamed resin heat insulating materials, have been provided. However, a floor structure that completely eliminates floor noise has not yet been provided.

  In the background as described above, an object of the present invention is to provide a floor structure that can significantly suppress or eliminate the occurrence of floor noise.

  The above-mentioned problem is that a joist oriented in the direction in which the hoist extends is interposed between the floor board made of structural plywood and the hoist, and a dry adhesive tape is interposed between the floor board and the joist. The floor structure is characterized in that both are joined in a slip-preventing state and the other joists except the joists are omitted from the lower surface side of the structural plywood.

  In this floor structure, the joist is oriented in the direction in which the large pull extends and is interposed between the floor board and the large pull, so that there is no gap between the large pull and the joist, thereby One of the causes of ringing can be eliminated.

  In addition, a dry adhesive tape is interposed between the floor board and the joist, and both are joined in a slip-preventing state, so it is possible to prevent the occurrence of squealing due to rubbing between the floor board and the joist, and the dry adhesive tape. Since the bonding is performed with a tape, the floor board is not warped as in the case of using an adhesive that generates water.

  Furthermore, since the other joists except for the joists described above are omitted from the lower surface side of the floor board, the cause of the floor noise due to the rubbing between the floor board and the joists is eliminated, and the floor board and the joists are joined with the dry adhesive tape. The area can also be reduced, making it easy to manufacture and construct, while the use of structural plywood as the flooring material can result in insufficient floor strength due to omission of joists. Nor.

  In the floor structure described above, a foamed resin heat insulating material is provided on the lower surface side of the floor board, and when the heat insulating material and the floor board are in a non-joined state at their opposing surface portions, the floor board and the foamed resin heat insulating material are joined. Generation of floor noise due to rubbing in the state can be prevented, and the floor board is not warped as in the case of using an adhesive that generates water. In addition, it is preferable that a heat insulating material and a floor board are non-contact.

  Further, in the floor structure described above, when the joists are made of a single body that serves as both the joists of the adjacent floor boards and the joists of the other floor boards in the width direction, it is caused by rubbing of the side faces of the joists. The occurrence of floor noise can be eliminated.

  Further, in the above floor structure, even when the joist is provided through the floor boards so as to pass through a plurality of floor boards, it is possible to eliminate or suppress the occurrence of floor noise due to rubbing between end faces of the joists. .

  Since the present invention is as described above, the occurrence of flooring can be significantly suppressed or eliminated.

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

  In the floor structure of the embodiment shown in FIG. 1 and FIG. 2, 1 is a steel bundle, 2 is a steel draw, 3 is a tree root, 4 is a floor board, 5 is a foamed resin heat insulating material made of styrene foam, etc. The floor board 4 is made of a thick plywood having a thickness dimension of, for example, 28 mm or 32 mm, and a planar size of, for example, 910 × 1820 mm. Then, on the upper surface portion of the large pull 2, a through joist 3 having a length of 1820 mm, which is twice the short side dimension of the floor board 4, for example, is placed in the direction in which the large pull 2 extends. A cushioning material such as felt may be provided between the joist and the large pull.

  And, to the joist 3, a dry adhesive tape 6 having an adhesive layer on both sides is adhered over the entire length so as to extend over the upper surface part and both side parts, and the width direction of the joist 3 through the dry adhesive tape 6. On the other half, the end of the long side direction of the floor board 4 is installed, and the floor board 4 and the joist 3 are joined to each other in a slip-preventing state by the dry adhesive tape 6, and the floor board 4 and the large pull 2 are The joists 3 are joined with screws 8 via the dry adhesive tape 6, and the other joists except the joists 3 from the lower surface side of the floor board 4 are omitted.

  And the lower surface part of the other adjacent floor board is mounted on one half part of the width direction of the joist 3, and the joist 3 is also used as the joist of the adjacent floor board 4. Moreover, the joists 3 are set longer than the length dimension in the short side direction of the floor board 4 as described above, and a plurality of joists 3 in the length direction, two sheets in the present embodiment, are provided. The floor board 4 is installed, and the joist 3 is a joist.

  Further, a foamed resin heat insulating material 5 is installed on the lower surface side of the floor board 4 in a height region between the joists 3 and 3, and the foamed resin heat insulating material 5 is suspended from the floor board 4 by a vinyl tape 7 or the like. The foamed resin heat insulating material 5 and the floor board 4 are bonded to each other by the adhesive that generates water or the nails and screws are directly passing through the heat insulating material 5 at their opposing surface portions. It is in a non-joined state that has not been done. In addition, the side part of the foamed resin heat insulating material 5 may be adhered to the dry adhesive tape 6 that is adhered to the side part of the joist 3.

  For example, as shown in FIGS. 3 (A) and 3 (B), for example, as shown in FIGS. 3 (A) and 3 (B), the foamed resin heat insulating material 5 is set on the floor board 4 installed on the work table. As shown, the vinyl tape 7 is wound to fix the foamed resin heat insulating material 5 to the floor plate 4 in a positioned state, and this is transported to the site.

  In addition, the foamed resin heat insulating material 5 may be fastened to the floor plate 4 by a shrink packing method or the like, and the point is that the foamed resin heat insulating material 5 only needs to be combined in a non-bonded state at the facing surface portions. Further, the vinyl tape 7 and the shrink packaging are for preventing the foamed resin heat insulating material 5 from falling below the floor, and other methods are employed that can prevent the foamed resin heat insulating material 5 from falling. If this is the case, this step in a factory or the like may be omitted.

  Then, at the site, as shown in FIGS. 4D and 4E, the joist 3 is installed on the steel pulling 2, and the dry adhesive tape 6 is applied to the joist 3, and then FIG. As shown in (f), the floor board 4 with the foamed resin heat insulating material 5 is placed on the joist 3 with the foamed resin heat insulating material 5 facing down, and the floor board 4 and the joist 3 are bonded with the dry adhesive tape 6. Finally, as shown in FIG. 5 (e), the floor plate 4 and the large pull 2 are joined with screws 8 at a pitch of 300 mm, for example.

  According to this floor structure, the joist 3 is directed between the floor plate 4 and the joist 2 so that the joist 3 is directed in the direction in which the jojo 2 extends. In this way, it is possible to prevent the occurrence of floor noise due to the gap between them.

  Further, since the dry adhesive tape 6 is interposed between the floor board 4 and the joist 3 and both the parts 4 and 3 are joined in a slip-preventing state, the occurrence of floor noise due to rubbing between the floor board 4 and the joist 3 is also possible. In addition, since the bonding is performed by the dry pressure-sensitive adhesive tape 6, the floor plate 4 is not warped as in the case of using an adhesive that generates water.

  Further, since the other joists except the joist 3 are omitted from the lower surface side of the floor board 4, the cause of the floor noise due to the rubbing between the floor board 4 and the joists is eliminated, and the floor board 4 and the joists are dry-type. The bonding area by the adhesive tape can also be reduced, making manufacture and construction easy. On the other hand, since a thick structural plywood is used as the floor board 4, the floor strength can be reduced by omitting the joists. There will be no shortage.

  Moreover, since the foamed resin heat insulating material 5 on the lower surface side of the floor plate 4 is in a non-bonded state with respect to the floor plate 4 as described above, the floor plate 4 and the foamed resin heat insulating material 5 are screwed. Generation of floor noise due to rubbing in the state of being joined with nails or the like can be prevented, and the floor board is not warped as in the case of using an adhesive that generates water.

  Furthermore, since the joists 3 are made of a single body that serves as both the joists of the adjacent floor board 4 and the joists of the other floor board 4 in the width direction, There is no occurrence, and the joist 3 is provided through the plurality of floor boards 4, 4, so that the occurrence of floor noise due to rubbing of the end face portions of the joists is eliminated or suppressed.

  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, there are no restrictions on materials, forms, dimensions, etc., such as joists, large draws, dry adhesive tapes, foamed resin heat insulating materials, etc., various ones may be used instead of the ones in this embodiment.
