Description

  The present invention relates to a baseboard structure for a sound insulation floor.

  Sound insulation floors such as floating floors or double floors are designed to absorb shocks by moving the floor up and down, so that the floor can be freely displaced up and down even on the floor near the wall. Insulated. For this reason, there is a problem in what configuration the baseboard installed on the boundary between the floor and the wall should be installed. That is, if the skirting board is fixed to both the floor and the wall, the vertical displacement of the floor is hindered by the wall, and sufficient sound insulation performance cannot be obtained, and if the skirting board is fixed to the wall and free from the floor, This creates a large gap between the skirting board and the floor surface.

  By the way, regardless of the sound insulation performance, in order to hide the gap caused by the sinking of the floor when heavy objects such as furniture are placed near the wall, the skirting board is fixed to the wall side, and the floor side timber is fixed to the wall side. A so-called two-stage skirting board is provided which is divided into two floor-side timbers to be fixed.

  However, the present inventor has conducted experiments and considerations on the sound insulation performance when using the two-stage skirting board for sinking as described above. It was confirmed that the sound insulation performance is not very effective.

  In other words, the two-stage skirting board intended to generate a gap due to the sinking of the floor certainly acts to insulate the floor and the wall. May be in contact. Therefore, in such a contact state, the floor side timber can slide on the wall side timber against the sinking of the floor due to the installation of heavy objects, but it follows the instantaneous movement as in the case of sound insulation. It was difficult to slide and slip.

  In addition, for construction reasons, the floor-side timber is generally installed so as to contact the wall surface. Therefore, the floor side timber works to try to hide the gap by sliding the wall against the sinking of the floor due to the installation of heavy objects, but it is difficult to follow the instantaneous movement as in the case of sound insulation, It was sometimes difficult to slip.

  The present invention has been made based on the above investigation, research, and factual elucidation, and provides a baseboard structure that does not impair the sound insulation performance of the floor and does not cause a gap. This is the issue.

The above problem is the floor side width wood fixed to the floor surface side,
Wall side width wood fixed to the wall surface side,
These both width timbers are provided with intermediate width timbers that are movable in the vertical direction with respect to the floor side timbers and engaged and held so as to be movable in the vertical direction with respect to the wall side timbers. ,
A holding material having a cushioning property for holding the intermediate-width timber at an intermediate height position so that the intermediate-width timber can be moved in both the vertical direction with respect to the floor-side width timber and can be moved in both the vertical direction with respect to the wall-side width timber. This is solved by a baseboard structure for a sound-insulating floor characterized in that is provided.

  In this skirting structure, in addition to the floor-side timber and the wall-side timber, an intermediate-width timber is provided, so that the floor-side timber, the intermediate-width timber, and the wall-side width The wood and the intermediate width wood can each be made slippery, and the baseboard can be prevented from impairing the sound insulation performance of the floor.

  Even if the floor-side timber and the intermediate-width timber are in contact with each other and it is difficult to slip, the wall-side timber and the intermediate-width timber do not interfere with the sound insulation performance of the floor due to relative displacement up and down, Further, even when the wall-side timber and the intermediate-width timber are in contact with each other and are not easily slipped, the floor-side timber and the intermediate-width timber are not displaced relative to each other up and down, thereby preventing the sound insulation performance of the floor from being disturbed. Thus, the baseboard structure of the present invention impairs the sound insulation performance of the floor even when the floor side width wood and the intermediate width wood or the wall side width wood and the intermediate width wood base are difficult to slip. Can be reliably prevented.

  Of course, it may be possible that the floor-side timber and the intermediate-width timber are not slippery, and the wall-side timber and the intermediate-width timber are less slippery, but that is a problem of probability, and that is a conventional two-stage skirting board. Compared to the above, it is possible to reliably prevent the baseboard from impairing the sound insulation performance of the floor.

  Moreover, the reason why the baseboard is divided is to prevent the gap from being generated in the first place, and it is possible to prevent the gap from being generated by the division structure of the floor side wood, the wall side wood and the intermediate width wood. it can.

  In the skirting board structure described above, a rubber-like elastic material may be interposed between the floor-side timber and the wall surface. In this case, a rubber-like elastic material is interposed between the floor-side timber and the wall surface even when the floor-side timber is in contact with or pressed against the wall surface. Therefore, the deformation of the rubber-like elastic material allows the floor-side timber to be displaced in the vertical direction with respect to the wall surface, thereby preventing the skirting board from impairing the sound insulation performance of the floor.

  In addition, when a rubber-like elastic material is interposed between the intermediate-width timber and the wall surface, even if the intermediate-width timber is in contact with or pressed against the wall surface, the intermediate-width timber Since a rubber-like elastic material is interposed between the wall and the wall surface, deformation of the rubber-like elastic material allows the intermediate-width timber to be displaced vertically with respect to the wall surface, and It is possible to prevent the sound insulation performance from being impaired.

Furthermore, the above-mentioned problem is a floor side width timber fixed to the floor surface side,
Wall side width wood fixed to the wall surface side,
This is also solved by a baseboard structure for a sound-insulating floor, characterized in that a rubber-like elastic material is interposed between the floor-side width wood and the wall surface.

  In this structure, it is possible to prevent a gap from being generated by dividing the floor-side width wood and the wall-side width wood, and the floor-side width wood is applied in a contact state or a pressed state with respect to the wall surface. Even when the rubber-like elastic material is interposed between the floor-side width wood and the wall surface, the deformation of the rubber-like elastic material causes the floor-side width wood to move vertically with respect to the wall surface. It is possible to prevent the baseboard from deteriorating the sound insulation performance of the floor.

In addition, the above-mentioned problem is that floor side width wood fixed to the floor surface side,
Wall side width wood fixed to the wall surface side,
These both width timbers are provided with intermediate width timbers that are movable in the vertical direction with respect to the floor side timbers and engaged and held so as to be movable in the vertical direction with respect to the wall side timbers. It is also solved by a baseboard structure for a sound insulation floor characterized by

  That is, even with such a structure, during the sound insulation operation of the floor, due to the action of the intermediate width wood, even if the floor side width wood and the intermediate width wood are difficult to slip, the wall side width wood and the intermediate width wood slide, Further, even if the wall-side timber and the intermediate-width timber are not easily slid, it is possible to prevent the skirting board from impairing the sound insulation performance of the floor by sliding the floor-side timber and the intermediate-width timber.

  Since the baseboard structure of the present invention is as described above, it does not impair the sound insulation performance of the floor and does not cause a gap.

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

  In the baseboard structure of the first embodiment shown in FIGS. 1 to 3, 1 is a sound insulation floor such as a double floor, 2 is a wall, 3 is a baseboard, and the floor 1 and the wall 2 are shown in FIG. Thus, the wall 2 is insulated so as not to disturb the sound insulation performance of the floor 1. The baseboard 3 provided at the boundary between the floor 1 and the wall 2 includes a floor-side width wood 4 that is fixed to the floor 1 and rises along the wall surface 2a, and a wall-side width that is fixed to the wall 2 side. A wood 5 and an intermediate-width wood 6 are provided, and these are made of, for example, metal, resin, wood or the like.

  The intermediate width timber 6 can move in the vertical direction with respect to the floor side width timber to the floor side width timber 4 and the wall side width timber 5 and can move in the vertical direction with respect to the wall side width timber 5. It is engaged and held so as to be. In addition, the intermediate width timber 6 is provided with a holding material 7 such as a tube material having a cushioning property between the floor side width timber 4 and the intermediate width timber 6, so that the intermediate width timber 6 is vertically extended with respect to the floor side width timber 4. It is movable and is held at an intermediate height position so that it can move in both the vertical direction with respect to the wall-side width wood 5. The holding material 7 may be interposed between the intermediate-width timber 6 and the wall-side width timber 5 so as to joint them. And in the installation state of these width | variety timbers 4, 5, and 6, it is comprised so that a clearance gap may not arise.

  In the above-mentioned skirting board structure, in addition to the floor-side timber 4 and the wall-side timber 5, an intermediate-width timber 6 is provided. The width timber 6 and the wall side width timber 5 and the intermediate width timber 6 can each be made slippery, and the skirting board 3 can be prevented from impairing the sound insulation performance of the floor 1.

  That is, when the floor 1 tries to be displaced downward as shown in FIG. 2 (a) due to sound insulation, the floor side width wood 4 descends following the movement, and further follows the middle. The width wood 6 is also lowered by its own weight, and the downward displacement operation of the floor 1 is allowed, and the sound insulation performance of the floor 1 is not hindered by the width board 3.

  In that case, even if the floor-side timber 4 and the intermediate-width timber 6 are in contact with each other and are not slippery, as shown in FIG. Is lowered integrally, so that the downward displacement operation of the floor 1 for sound insulation is not hindered by the baseboard 3.

  In addition, if the wall side width wood 5 and the intermediate width wood 6 are in contact with each other and are not slippery, the floor side width wood 4 and the intermediate width wood 6 Is relatively displaced in the separating direction, and the lowering displacement operation of the floor 1 for sound insulation is not hindered by the baseboard 3.

  On the other hand, when the floor 1 tries to displace upward as shown in FIG. 3 (a) due to sound insulation, the floor-side width wood 4 descends and further follows the movement. The intermediate width timber 6 is also raised, and the upward displacement operation of the floor 1 is allowed, and the sound insulation performance of the floor 1 is not hindered by the skirting board 3.

  In this case, even if the floor-side timber 4 and the intermediate-width timber 6 are in contact with each other and are not slippery, the intermediate-width timber 6 is replaced with the floor-side timber 4 as shown in FIG. Since it rises following, the base plate 3 is not hindered by the skirting board 3 from moving up and down for sound insulation.

  In addition, if the wall-side timber 5 and the intermediate-width timber 6 are in contact with each other and are not slippery, as shown in FIG. However, the base plate 3 is not displaced by the skirting board 3 due to relative displacement in the approaching direction while crushing the holding member 7, and the downward displacement operation of the floor 1 for sound insulation.

In the baseboard structure of the second embodiment shown in FIG. 4 (a), the first rubber-like elastic material 8 is interposed between the floor-side width wood 4 and the wall surface 2a, and the intermediate-width wood 6 and the wall surface. The 2nd rubber-like elastic material 9 is interposed also between 2a. These rubber-like elastic materials 8 and 9 may or may not be bonded to the wall surface 2a. Further, the rubber-like elastic material 8, 9 reasons construction choice, as shown in FIG. 5, although it is common being bonded to the floor side width timber 4 and the intermediate width timber 6, floor side The width wood 4 may not be bonded. Others are the same as the skirting board structure of 1st Embodiment.

  With this structure, not only the same operational effects as the baseboard structure of the first embodiment but also the following operational effects are exhibited. That is, even when the floor-side width wood 4 is constructed in contact with or pressed against the wall surface 2a, the first rubber-like elastic material 8 is between the floor-side width wood 4 and the wall surface 2a. Since the rubber-like elastic material 8 is deformed, the floor-side width wood 4 can be displaced in the vertical direction with respect to the wall surface 2a, thereby impairing the sound insulation performance of the floor 1. Can be prevented.

  Even when the intermediate width wood 6 is in contact with or pressed against the wall surface 2a, the second rubber-like elastic material 9 interposed between the intermediate width wood 6 and the wall surface 2a is provided. By deforming, the intermediate width wood 6 can be displaced in the vertical direction with respect to the wall surface, thereby preventing the sound insulation performance of the floor 1 from being impaired.

  The skirting board structure of the third embodiment shown in FIG. 4 (b) is a so-called two-stage skirting board constituted by a floor side timber 4 and a wall side timber 5 in which an intermediate width timber is omitted, A rubber-like elastic material 10 is interposed between the floor-side width wood 4 and the wall surface 2a.

  In this structure, not only can the gap be eliminated, but even when the floor-side timber 4 is in contact with or pressed against the wall 2a, the floor-side timber 4 and the wall 2a When the rubber-like elastic material 10 interposed between the two is deformed, the floor-side width wood 4 can be displaced in the vertical direction with respect to the wall surface 2a, thereby impairing the sound insulation performance of the floor 1. Can be prevented.

  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 structure of the first embodiment described above, the holding material 7 may be omitted. In that case, the intermediate-width timber 6 will be supported by the floor-side width timber 4 by its own weight, but even so, during the sound insulation operation of the floor 1, Even if the width timber 4 and the intermediate width timber 6 are difficult to slip, the wall side width timber 5 and the intermediate width timber 6 are slipped, and even if the wall side width timber 5 and the intermediate width timber 6 are not slippery, the floor side width It is possible to prevent the baseboard 3 from impairing the sound insulation performance of the floor 1 by sliding the wood 4 and the intermediate width wood 6.

  Moreover, in said 2nd Embodiment, the rubber-like elastic materials 8 and 9 are interposed by both between the floor side width | variety timber 4 and the wall surface 2a, and between the intermediate width | variety timber 6 and the wall surface 2a. Although a case has been shown, a rubber-like elastic material may be interposed between any one of them. Moreover, there is no restriction | limiting in the specific form of wall side width | variety timber, floor side width | variety timber, and intermediate | middle width | variety timber. There is no limit.
