"The Japanese-style room" means a space with tatami mats)
The sill is located at a boundary B between R1 and a floor bedding portion (in the present specification, a "floor portion" refers to a space other than the Japanese-style room portion such as a Western-style room, a corridor, a kitchen, a toilet, a lavatory, etc.). 3 is fixed, and a thin tatami mat 4 is arranged on the floor base A of the Japanese-style room part R1, a floor finishing material 5 is arranged on the floor mat A of the floor covering part R2, and the sill 3, the thin tatami mat 4, The floor finishing material 5 has substantially the same height.

[0010] The floor base A is, as shown in Figs.
It is arranged on various frame structures C, such as concrete panels such as ALC, floor panels with a surface material attached on a framework formed by joining steel or wooden frames in a rectangular shape, and panels with a surface material attached on a plurality of joists. Is done.

The concrete panel such as ALC, the surface material of the floor panel, and the surface material on the joist may be used as the floor base A. In this case, the frame C is made of a concrete panel such as ALC or a floor panel. And the joists and the like.

The floor substrate A has an upper surface A1 extending at the same height, and is fixed on the frame C by using a fixing tool such as an adhesive and / or a screw. In the example, the base plate 2 is formed by a series of three base plates 2, 2, 2 which are vertically overlapped (a concrete panel such as ALC may be used as the base plate 2, and in this case, the floor base A may form the frame C). is there).

The series of base plates 2 may be in the form of an integral plate, or may be formed from a plurality of base plate pieces arranged at the same height with their edges abutting.

The sill 3 is attached to the floor base A. Further, the sill 3 is provided with a rail portion 6 on which the sliding door D slides on the upper surface.

Further, as shown in FIGS. 2, 3, and 5, the sill 3 is provided with the rail portions 6, 6 formed of two grooves 11, 11.
The sill body 12 having a recess formed on the upper surface thereof, and the sill body 1
And the rail member 13 which covers the groove bottom surfaces 11A, 11A of the two rail portions 6, 6 and receives the sliding door D.

[0016] The threshold body 12 is, for example, long material produced by extrusion of the synthetic resin, the substrate 19 to form a flat the groove bottom surface 11A, 11A, the groove bottom face 1
Between 1A and 11A and on both sides thereof, a hollow portion 25 having the same upper surface and extending in the longitudinal direction is formed, and raised portions 26, 26, 26 having a substantially rectangular cross section are provided integrally.

The rails 6, 6 are provided with grooves 11, 11
A series of locking recesses 14, 14 extending continuously in the longitudinal direction are provided at the lower portions on both side surfaces of the lock member.

As shown in FIGS. 3, 4, and 7, the sill main body 12 is formed by driving a fixing tool 15 such as a finishing nail, which passes through the groove bottom surface 11A of the rail section 6 from above, into the floor base A. It is located on the boundary B between the Japanese-style room portion R1 and the floor covering portion R2 and between the vertical frames 41 facing the wall opening 40, and is fixed to the upper surface A1 of the floor base A. In addition,
At the time of the fixing, an adhesive may be used in combination.

Therefore, it is not necessary to strike the fixing tool 15 obliquely, and it is possible to perform the work easily and to use the floor bases A and / or
Alternatively, even when the frame C is a base material made of a material such as ALC which is unlikely to hit the fixing tool 15 at an angle, the sill main body 12 can be easily attached without damaging the base material.

The rail member 13 is made of, for example, polyethylene or another suitable synthetic resin, and has a base 27 having a flat and long cross section.
On the upper surface of the base body 27, a plurality of ridges 29 extending in the length direction are formed in order to improve the sliding of the sliding door D.

The both sides of the base member 27 of the rail member 13 form a tapered portion 30 by smoothly curving the lower surface, and as shown in FIG.
The one side edge of the base 27 formed by the tip of the base member is locked to one of the locking recesses 14 of the sill main body 12, and the base 27 is rotated about the locked portion as shown by an arrow in FIG. By locking the other side edge to the other locking recess 14, the rail member 13 can be easily attached to the sill main body 12 with one touch (fitting type) by covering the groove bottom surface 11 </ b> A of the rail portion 6. As a result, a groove for sliding the lower surface of the sliding door D is formed.

The rail member 13 is provided on the sill main body 1.
The rail member 13 can be easily removed because the rail member 13 is attached by the above-mentioned locking without being adhered to the base member 2, thereby facilitating maintenance.

Further, since the head 15A of the fixing member 15 is covered with the base member 27 of the rail member 13, the head 15A of the fixing member 15 is not exposed on the surface, thereby providing a beautiful finish. Can be done.

The upper end of the sliding door D whose lower end is slidably supported by the rail section 6 of the threshold 3 is provided above the threshold 3 in this example, as shown in FIG. It is slidably supported by the upper rail portion 31 of the lower gate 9 at the lower end of the hanging wall 7.

The Kamoi 9 faces the wall opening 40,
In the present example, it is bridged between the vertical frames 41, 41.

On the upper surface A1 of the floor base A of the Japanese-style room portion R1, one or more thin tatami mats 4 including a thin tatami mat 4 substantially abutting on one side surface of the sill 3 are laid.
On the upper surface A1 of the floor base A of the floor covering portion R2, the floor finishing material 5 is laid so as to substantially contact the other side surface of the sill 3.

The thin tatami mat 4 has a tatami mat member 23 attached to the periphery of the tatami mat body 22. As the floor finishing material 5,
In addition to a flooring block, a flooring board, and a carpet, a cushion material 5A that prevents transmission of sound and vibration to lower floors, that is, is excellent in sound insulation performance and vibration suppression performance, can be suitably used.

The sill main body 12, the thin tatami mat 4, and the floor finishing material 5 of the sill 3 have substantially the same height. Here, “substantially the same height” refers to a step of 5 mm or less that does not cause any problem in terms of safety.

The thickness T3 of the sill main body 12 of the sill 3, the thickness T4 of the thin tatami mat 4, and the thickness T5 of the floor finishing material 5 are as follows.
Each of them is in the range of 2 mm or more and 10 mm or less, and by making them substantially the same thickness, the above “substantially the same height” can be obtained. For example, the thickness T3 is about 6 mm, the thickness T4 is about 6 mm, T5 can be about 3.5 mm.

If the thicknesses T3, T4, T5 are smaller than 2 mm, it becomes difficult to manufacture the sill 3, the thin tatami mat 4, and the floor finishing material 5 and the durability tends to decrease. It is difficult to secure sound insulation performance and vibration suppression performance when the material 5A is used. Therefore, each thickness T3, T4, T
5 is preferably 2 mm or more, more preferably 2.5 mm or more, and still more preferably 3 mm or more.

If the thicknesses T3, T4 and T5 are larger than 10 mm, the threshold 3, the thin tatami mat 4 and the floor finishing material 5 must be made unnecessarily thick. It is necessary to use a special thick-walled structure, which tends to lead to an increase in cost and a decrease in workability. In addition, the sill 3 becomes excessively thick, and oblique hitting of the fixing tool 15 may not be avoided. Therefore, each thickness T3, T4, T5 is 10 mm or less, more preferably 8 mm or less, and further preferably 6.5.
mm or less.

As described above, even if the sill 3 is relatively thin in conformity with the thickness T4 of the thin tatami mat 4, since the sill 3 is provided with the rails 6, the ditch 9 at the lower end of the hanging wall 7 , The sliding door D can be slid.

Further, in order to form a floor base A in which the upper surface A1 extends at the same height by a series of base plates 2, a sill 3, a thin tatami mat 4, and a floor finishing material 5 having substantially the same thickness are prepared. The sill 3, the thin tatami mat 4, and the floor finishing material 5 can be made substantially the same height, the floor step between the Japanese-style room part R1 and the floor covering part R2 can be eliminated, and the floor base of the floor covering part R2 for eliminating the floor step. For example, it is possible to eliminate a floor step without changing the configuration of the floor base and the frame structure, such as increasing the height of the floor, and with a simple configuration, without requiring any special labor for construction.

In the present invention, the sill 3 is placed at the boundary between the Japanese-style room and the Japanese-style room and the floor base A, at the boundary between the floor-laying part and the floor-laying part and the floor base A, or at the outdoor end such as the edge. Along the way, it may be fixed to the floor base A.

[0035]

According to the sill mounting structure of the first aspect of the present invention, it is not necessary to slantly hit a fixing device for fixing the sill main body to the floor substrate, and it is possible to easily perform the installation, and the floor substrate slants the fixing device. Even if the material is difficult such as ALC, the threshold main body can be easily attached. Further, since the head of the fixing tool is covered with the rail member, the head of the fixing tool is not exposed on the surface, and a beautiful finish can be obtained.

According to the second aspect of the present invention, the rail members can be easily attached to the sill main body with one touch by locking the both side edges of the rail member with the locking concave portions of the sill main body. Further, since the rail member can be attached to the sill main body without being adhered, the rail member can be easily removed and maintenance can be facilitated.

Further, according to the third aspect of the present invention, the sill main body of the sill can be more securely attached by the fixing tool without slanting the fixing tool without being slanted.
