BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the examples shown in the drawings. FIG. 1 is an example of a sliding window using a lower frame mounting structure of a window sash for a two-by-four house according to the present invention, showing its longitudinal section, and FIG. 2 is its transverse section. Is. The sliding window shown in Fig. 1 is a sash frame for windows of a two-by-four house in which an upper frame, a lower frame, and left and right vertical frames are combined in a square shape, and two shoji screens are installed in a sliding shape. It is attached in a semi-external state to the opening of the outer peripheral portion of the building constituted by. And the lower frame 1 of the window sash of this two-by-four house is
A main frame integrally formed by extrusion, and an attachment 13 for the end portion of the floor finishing material 12, which is used by locking the main frame,
It is composed of 17 and. The main frame has a screen door rail 3, an outdoor door rail 4, and an indoor door rail 5, which are integrally formed on the upper surface 2 with a high step in the indoor direction. A partition plate 6 having the same height as the shoji rail 5 is provided. The screen door rail 3 and the outdoor sliding door rail 4 are provided in a hollow frame portion, and the attachment piece 8 is attached from the indoor end of the lower surface of the frame portion.
Are extended, and are attached to the outside lateral surface of the side joist 7 with nails 9. In addition, the indoor shoji rail 5
The frame portion having the partition plate 6 and the partition plate 6 is mounted on the upper surface 10 of the side joist 7 having no end portion of the underfloor 11 and the mounting piece 14 provided at the lower portion is screwed with the screw 18 to be mounted. The upper surfaces of the indoor-side shoji rail 5 and the partition plate 6 are configured to be substantially equal to or slightly lower than the upper surfaces of the floor finishing material 12 such as a flooring placed on the underfloor 11. Note that the structural plywood of the underfloor 11 has a standard of 910.
Since it is 18 mm in width and 18 mm in width, when the floor joists are laid on the floor joists, a slight gap is generated on the end joists and the side joists in terms of dimensions, and the floor joists spacers 15 are normally used for closing. Therefore, it is advisable to use this gap and leave a gap without using the floor plywood spacer 15, and use this gap as a mounting space for the frame portion having the indoor shoji rail 5 and the partition plate 6. In the case of a floor plywood spacer 15 that does not require a space and has no gap, the end portion of the floor subbing material 11 is cut to a predetermined length to form a mounting space on the side joist 7 or the upper surface of the end joist.

Next, the attachment 1 for the end of the floor finishing material 12, 16 which is used by being locked to the partition plate 6 on the indoor side of the main frame.
3 and 4 are enlarged views of the lower frame mounting structure of the present invention, and FIG. 3 shows a floor finish material 12 on which a flooring is used on the floor subbing material 11. Therefore, this attachment 13 has the same opening width as that of two right-angled surfaces that press the corners of the end portion 19 of the floor finishing material 12 and a bifurcated locking piece 20 that fits on the tip portion of the partition plate 6. It is a frame body having a length and is configured to be attached to the end portion 19 of the floor finishing material 12 with a screw so as to eliminate a step as shown in FIG. Even if there is a difference in height between the upper surface of the floor finishing material 12 and the upper surface of the partition plate 6, it can be locked by adjusting the depth of the two forks of the locking piece 20.
FIG. 4 shows a carpet that is bent as the floor finishing material 16 on the underfloor 11 and the attachment 17 has a recessed end 21 due to the flexibility of the carpet so that the partition plate 6 protrudes to form a step. This attachment 17 has an opening width L-shaped so as to hold a space formed by being surrounded by the end portion 21 of the carpet, the side joists 7 and the subfloor material 11. As shown in FIG. 4, the frames are of the same length, and are configured to be screwed to the side joist 7 with screws from the upper surface so that no step is formed. It should be noted that one end of the attachment 17 is locked to a locking portion 22 provided at the base of the partition plate 6, and the other end is formed with a leg portion 23 so as to be placed on the upper surface 10 of the side joist 7. If a hook is formed at one end of the engaging portion 22 of the partition plate 6 and the attachment 17 engaged with the engaging portion, the attachment 17 can be provided without being screwed. Further, in order to use the underfloor 11 having different thicknesses, an extension portion that can be bent and removed is provided at the lower end of each of the one end where the attachment 17 is locked and the other end that becomes the leg 23, It is also possible to adjust the height by appropriately bending and removing depending on the thickness of the underfloor material 11.
