In some cases, there is no deformation (out-of-order) as in the case of waste, the positioning is easy, the variation in quality due to the skills of carpenters is small, and no problems such as floor noises occur after construction.

  As the material of the angle material, it is optimal to use a steel material in terms of strength, but a hard resin material or the like may be used. Further, 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 two surfaces of the flat portion.

  The length of the angle material can be the same as the entire length of the end of the double floor, but there is a concern that fixing the floor base material and the vertical member entirely will adversely affect the floor impact sound insulation performance. You. Therefore, it is preferable that a plurality of angle members be attached to the end of the double floor with a space therebetween, and a partial point installation is provided. In this case, the mounting pitch of the angle members is preferably 200 mm or more.

  Further, 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 cushioning material. In addition, the position of the buffer material is laminated on the upper surface of the floor base material, or disposed on the side surface or lower surface of the floor base material according to the direction of the angle material.

  As a material of the cushioning material, a wood material, a resin material, a rubber material, etc. can be used, but when the cushioning material is laminated on the upper surface of the floor base material, it should be hard considering that a load acts. Is preferred. Specifically, the hardness of the cushioning material is such that when the standard weight of an adult is added to the edge of the double floor where the cushioning material is interposed, the sinking amount of the edge of the double floor is 1 mm or less. As described above, the selection is made in consideration of the bending rigidity of the floor covering material and the finishing material, the position of the support leg, the hardness of the rubber foot, and the like.

  In addition, a discarding plate is usually interposed between the floor covering material and the finishing material, but when the cushioning material is laminated on the upper surface of the floor covering material and the angle material is attached, the discarding plate is arranged in this portion. Since it disappears, 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 be equal to or less than the thickness of the discarded plate. In addition, the end structure of the double floor of the present invention can also be applied to a floor construction method without a discarded plate, in which case the finishing material is directly fixed to the floor base material, but in this case, Also, make sure that the angles are not exposed on the floor surface.

  Further, it is preferable to add a support leg for preventing sinking near the angle member in order to suppress sinking of the floor base material itself. Specifically, apart from the normal support legs, 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 member is attached, and the hardness of the rubber foot of the support leg is added. Is made harder than normal rubber feet (JIS A 60 ° or more), it can exhibit the function of suppressing sinking of the flooring material, reduce the load load on the angle material, and achieve the edge of the floor. The sink of the floor when a person gets on the vehicle can be suppressed to 1 mm or less.

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