  However, in the end structure using the border neda, the border neda may be deformed or frayed due to the shrinkage of the mud material, which is the border neda material. There was a case where a problem occurred between the joints with Neda. That is, there are concerns about problems such as sinking of the double floor, ringing due to rubbing between the double floor and the vertical member, and generation of a gap between the double floor and the vertical member.

  In addition, since Neda installs raw materials at the construction site, there are cases where the installation accuracy is poor and the degree of integration with vertical members may vary widely. There is also. In addition, the use of neda may adversely affect the floor impact sound insulation performance.

  And such a problem exists also in the double floor without a discard board. That is, as shown in FIG. 11, in the case of a double floor without a discarding board, the receiving material 8 is attached on the support leg 4 and the floor base material 1 is arranged on the receiving material 8. At the part, the space between the floor base material 1 and the border tie 30 is fixed with a nail or the like. Therefore, as long as the Neda is used, the above problem occurs.

  Therefore, the present invention relates to a double floor mainly used in an apartment house, an office, a game room, etc., and it is possible to stabilize the construction quality, improve the workability, and further improve the sound insulation performance. The object is to provide an end structure.

  The gist of the present invention consists of a double floor end having a floor base material (1) and a finishing material (3) and installed on a base (10) via support legs (4), and a base (10). It is a structure for fixing the vertical member (20) that rises further, and the first fixing tool (5) with the tip piece facing downward is fixed to the edge of the floor base material (1) by fixing the first fixing tool (5). The member (20) is fixed with a second fixing tool (6) facing the first fixing tool (5) and having the tip piece facing upward with a gap, and the tip piece of the first fixing tool (5). And the end piece of the second fixture (6), preferably with an end structure of a double floor in which a vibration isolating material (9) is interposed therebetween.

  And usually, it is a double floor in which a discard plate (2) is interposed between the floor base material (1) and the finishing material (3), and this is for attaching the first fixture (5). It is preferable to provide a notch.

  In addition, when using a vibration isolator (9), it is the most preferable structure to interpose on both surfaces of the front-end | tip piece of a 1st fixing tool (5).

  The end structure of the double floor of the present invention has a floor base material and a finishing material, and fixes the end of the double floor installed on the base via support legs and the vertical member rising from the base. When the tip piece and the locking piece of the first fixing tool with the tip piece facing downward and the second fixing tool provided with the locking piece are fitted together, it is preferably fitted via a vibration isolating material. Because it has a combined end structure, it is possible to stabilize the construction quality, improve the workability, and further improve the sound insulation performance, mainly for double floors used mainly in apartment buildings, offices, and game rooms. .

  The present invention improves the sound insulation performance by insulating the vibration of the floor generated during residence by the vibration-proof structure of the floor and the vertical member. Furthermore, it prevents the gap due to the contraction of the floor, prevents the sinking of the end of the floor, and the function of preventing the ringing of the floor. Specifically, the double floor of the present invention includes a floor base material and a finishing material. And installed on a base via support legs. The end of the double floor relates to an end structure that is fixed to a vertical member that rises up from the base. The first fixing member and the second fixing member are connected between the floor base material and the vertical member, respectively. Fix with etc.

  In particular, it is a structure in which the downward-facing tip piece of the first fixture and the locking piece of the second fixture are preferably fitted via a vibration isolator. Thus, the end structure of the double floor of the present invention is a structure that does not use neda like the conventional structure, and therefore, there is no deformation (inconsistency) like neda when it is wood raw material. Positioning is easy, there is little variation in quality due to carpentry skills, and no problems such as flooring occur after construction.

  The first and second fixtures may be made of metal or resin, and are not particularly limited. Depending on the case, it may be made of rubber or resin having a vibration-proof property. Furthermore, the whole fixture may be an integral type, but may be partially made of a different material, for example, the attachment portion is made of metal or hard resin, and the tip piece May be a relatively elastic resin material having anti-vibration properties.

  The lengths of the first and second fixtures can be the same as the total length of the ends of the double floor, but if the floor base material and the vertical member are fixed completely, the floor impact sound blocking performance is adversely affected. There is a concern that Therefore, it is preferable that these are attached to the ends of the double floor at intervals to make a partial installation. Of course, partial installation is preferable in terms of workability and anti-vibration effect.

  A rubber elastic body, a soft resin material, or a resin foam material is preferably used as the vibration isolator used by being sandwiched between the first and second fixtures. Of course, these composites may be used, for example, a rubber elastic body in which a fiber layer is embedded. In terms of material, it is desired to have a property that is hard in the horizontal direction and soft in the vertical direction when used between the tip piece and the locking piece. These are usually preliminarily bonded to the tip piece or the locking piece of the first or second fixture, but may be non-adhesive and fitted.

  A discard plate is usually interposed between the floor base material and the finishing material. However, if the first fixture is attached to the upper surface of the floor base material, the discard plate cannot be disposed at this portion. Therefore, in this case, the thickness of the attachment portion of the first fixture located on the upper surface portion of the floor base material is set to be equal to or less than the thickness of the discarded plate interposed between the floor base material and the finishing material. It is preferable.

  The end structure of the double floor of the present invention can be applied to a floor method without a discard board, and in that case, the finishing material is directly fixed to the floor base material. The first fixture should not be exposed on the floor surface. In this case, it is desirable to provide a notch in the floor base material with respect to the attachment portion of the first fixture.

  The first fixing tool is fixed to the edge of the floor base material, but this fixing part may be cut out of the edge of the floor base material and fixed to the notched part. It is not limited.
