  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. 7, in the case of a double floor without a discard 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 the end of the double floor capable of stabilizing the construction quality, improving the workability, and improving the sound insulation performance. The purpose is to provide a structure.

The present invention has been made in order to solve the above problems, and the gist of the present invention is to provide an end portion of a double floor which has a floor base material and a finishing material and is installed on a base via support legs. The structure is for fixing a vertical member installed on a base, and is fixed between the floor base material and the vertical member by an angle material having an L-shaped cross section , and the upper surface of the floor base material and the angle material It relates to an end structure of a double floor in which a cushioning material is interposed therebetween .

  And preferably, a plurality of angle members are attached to the end portions of the double floor at intervals, and more preferably, the end structure of the double floor has an angle member attachment pitch of 200 mm or more. It is concerned.

  In addition, it is preferable to interpose a cushioning material between the floor base material and the angle material. In this case, the total thickness of the cushioning material and the angle material laminated on the upper surface of the floor base material is equal to the floor base material and the finish. The thickness is preferably equal to or less than the thickness of the discard plate interposed between the two. Furthermore, it is preferable that a support leg having a rubber foot with a hardness of 60 ° (JIS A) or more is added at a position within 100 mm from the end of the floor base material to which the angle member is attached.

  The floor base material may be provided with a notch for attaching the angle material, or the floor base material and the vertical member may be arranged apart from each other, and the angle material may be attached to the gap between the floor base material and the vertical member.

  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 installed on the base. Since the floor base material and the vertical member are fixed by an angle material having an L-shaped cross section, the double floor mainly used in an apartment house, an office, a game room, etc. In addition, the construction quality can be stabilized, the workability can be improved, and the sound insulation performance can be improved.

  And especially when multiple angle materials are attached to the edge of the double floor with a gap, or when a cushioning material is interposed between the floor base material and the angle material, the floor impact sound The blocking performance is further improved.

  The double floor in this invention has a floor base material and a finishing material, and is installed on a base | substrate via a support leg. And the edge part of this double floor is fixed to the vertical member installed in the base | substrate. In the double floor of the present invention, regarding such an end structure, an angle material having an L-shaped cross section is used, and the floor material and the vertical member are fixed with screws or the like by the angle material.

  In this way, the double floor end structure of the present invention is fixed using an angle material having an L-shaped cross section without using a neda like the conventional structure. In some cases, there is no deformation (distortion) like Neda, positioning is easy, there is little variation in quality due to carpentry skills, and no problems such as flooring occur after construction.

  As the material of the angle material, it is optimal to use a steel material in terms of strength, but it may be a hard resin material or the like. The thickness is preferably 0.5 mm or more in the case of a steel material, and it is preferable to provide screws or nail holes for fixing the floor base material and the vertical member on the two surfaces of the flat portion.

  The length of the angle material can be the same as the total length of the end of the double floor, but there is concern that the floor impact sound insulation performance will be adversely affected if the floor base material and the vertical member are completely fixed. The Therefore, it is preferable that a plurality of angle members are attached to the ends of the double floor with a space between them to make a partial point installation. In this case, the mounting pitch of the angle members is preferably 200 mm or more.

  In addition, the angle material can be directly fixed to the floor base material, but it is preferable to interpose a cushioning material between the angle material and the floor base material. This is because a vibration insulating effect can be obtained by the buffer material. The position of the cushioning material is laminated on the upper surface of the floor base material or arranged on the side surface or lower surface of the floor base material in accordance with the direction of the angle material.

  Wood material, resin material, rubber material, etc. can be used as the material of the buffer material, but when the buffer material is laminated on the upper surface of the floor base material, it should be hard considering the load acting on it. Is preferred. Specifically, when the standard weight of the adult is added to the end of the double floor where the cushioning material is interposed, the amount of subsidence at the end of the double floor becomes 1 mm or less. Thus, the selection is made in consideration of the bending rigidity of the floor base material and the finishing material, the position of the support leg, the hardness of the rubber foot, and the like.

  In addition, a discard plate is usually interposed between the floor base material and the finishing material. However, when an angle material is attached by stacking cushioning material on the top surface of the floor base material, a discard plate is placed in this part. Therefore, the finishing material is laminated on the angle material. Therefore, in such a case, it is preferable that the total thickness of the cushioning material and the angle material is equal to or less than the thickness of the discard plate. In addition, 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. Also, make sure that the angle material is not exposed on the floor surface.

  Furthermore, in order to suppress the sinking of the floor base material itself, it is preferable to add support legs for preventing sinking in the vicinity of the angle member. Specifically, apart from the normal support leg, a support leg for preventing sinking is added at a position within 100 mm from the end of the floor base material to which the angle material is attached, and the hardness of the rubber leg of this support leg Is harder than normal rubber feet (JIS A 60 ° or more), it can exert the function to suppress the sinking of the floor base material, can reduce the load load on the angle material, the floor edge The sinking of the floor when a person gets on can be suppressed to 1 mm or less.

  In some cases, a discarded plate is not interposed between the floor base material and the finishing material. In this case, the mounting location of the angle member becomes a problem. Therefore, in such a case, the floor base material is provided with a notch for attaching the angle material, or the floor base material and the vertical member are separated from each other, and the angle between the floor base material and the vertical member is set. What is necessary is just to attach a material.
