In this construction method, as shown in FIGS. 3A and 3B, a sash frame without a vertical frame having only the upper frame 1 and the lower frame 3 is attached to the opening R. Even if there is no sash frame, the position of the upper frame 1 and the lower frame 3 in the height direction and the entry / exit direction is taken, and the roller 20 at the upper end of the upper suspension doors 4a, 4b, 4c runs on the guide rail 2 of the upper frame 1 On the other hand, sliding of the pivot 21 at the lower end of the upper suspension doors 4a, 4b, 4c is guided in the rail groove 15 of the lower frame 3, and the upper suspension doors 4a, 4b, 4c are in a state perpendicular to the upper and lower frames 1, 3 It is necessary to install with. In this construction method, a lower frame hanging jig 5 comprising an upper frame locking tool 6, a bar 7 and a lower frame mounting tool 8 is used. First, the upper frame 1 is attached to the opening R, and the upper frame 1 After the lower frame 3 is suspended in a horizontal state by four lower frame lifting jigs 5 from the four corner positions in plan view of the vertical guide rail 2, the concrete 28 is applied to the legs 22 of the lower frame 3 and hardened. The lower frame hanging jig 5 is removed from the upper frame 1 and the lower frame 3 to complete the construction.

  As shown in FIG. 1, the lower frame hanging jig 5 has a size between the upper and lower frames 1, 3 by attaching an upper frame locking tool 6 and a lower frame mounting tool 8 on one side and the other side in the longitudinal direction of the bar 7. The length is formed to be approximately the same. The rod member 7 uses a mold member having a square cylindrical cross-sectional shape. The rod member 7 has one end side peripheral wall in the longitudinal direction of the rod member 7 and the other end portion peripheral wall on the mounting screw hole 24. The laterally long holes 25 are arranged at intervals in the vertical direction, and the mounting screw holes 24 are for passing the mounting screws 13a in the horizontal direction and screwing the lower frame mounting tool 8 to the bar 7. When the lower frame hanging jig 5 is locked to the upper frame 1 and the lower frame 3 is suspended, the horizontally long hole 25 is formed to be long in the horizontal direction. The upper claw locking device 6 can be detachably attached by locking the locking claws 10a, 10a of the upper frame locking device 6 described later. The mounting screw hole 24 and the laterally long hole 25 are arranged so as to have a symmetrical positional relationship with one end and the other end in the longitudinal direction of the bar 7. Can also be used on the upper and lower sides. Note that the laterally long hole 25 only needs to be able to engage the locking claws 10a and 10b, and thus does not necessarily have to penetrate as in the present embodiment.

  The upper frame locking tool 6 has a hook-shaped locking portion 9 having a downward concave portion P that can be hooked from the upper side with respect to the vertical guide rail 2 protruding upward from the upper frame 1. The lower part 10 of the upper frame locking tool 6 has a downward U-shape that can sandwich an end-side peripheral wall on one side in the longitudinal direction of the bar 7 from the outside. Locking claws 10 a, 10 a that can be locked in the horizontally long holes 25, 25 of the bar 7 protrude from the hanging piece of the lower part 10 of the upper frame locking tool 10 facing the peripheral wall.

  The lower frame fixture 8 has a vertical attaching / detaching portion 11 having a plate shape that can be inserted into the lower cylindrical hole of the bar member 7, and a plate shape bent horizontally from the lower edge portion of the attaching / detaching portion 11. It has the contact part 12 with the frame 3, and forms the whole in a substantially L shape. The attachment / detachment portion 11 has adjustment screw holes 23 a and 23 b at two positions spaced apart in the vertical direction, and the upper adjustment screw hole 23 a attaches the contact portion 12 to the bottom U of the rail groove 15. The lower adjustment screw hole 23 b is used when the lock seat 14 is attached to the bottom U of the rail groove 15 of the lower frame 3, and is a component attached to the lower frame 3. In accordance with the shape of the lower frame 3, either the upper or lower adjustment screw holes 23 a, 23 b and the mounting screw hole 24 of the bar 7 are matched to each other, and the mounting screw 13 a is screwed. The fixture 8 and the bar 7 are detachably attached. The abutting portion 12 faces the bottom portion U of the rail groove 15 of the lower frame 3 in the vertical direction and abuts in a planar shape, and the upper suspension doors 4a and 4b of the rail groove 15 when the abutting portion 12 abuts the bottom portion U. 4c has a notch 26 at one end in the traveling direction, and the lower frame fixture 8 is screwed to the lower frame 3 with the lock seat fixing screw 13b or the fixing screw 13c at the notch 26. ing. The notch 26 has a notch width slightly wider than the diameter of the screw part of the lock seat fixing screw 13b and the fixing screw 13c, so that the abutting part 12 is slid along the bottom U to be notched. Since the screw portion of the fixing screw 13c can be sandwiched by the portion 26, the contact portion 12 can be easily attached to the lower frame 3. Since the lower frame hanging jig 5 of the present invention can attach and detach the upper frame locking tool 6 and the lower frame mounting tool 8 to the bar 7, the bar 7 of the lower frame hanging jig 5 is matched to the height of the site. Only the upper frame locking tool 6 and the lower frame mounting tool 8 can be used in common by replacing only these.

The procedure of the work in the construction method of the sash frame of this invention is demonstrated below based on Fig.2 (a) (b) (c) (d) (e).
Here, a three-storied sash frame is taken as an example.
First, as a first step, a procedure for attaching the upper frame 1 to the opening R will be described. As shown in FIGS. 2A and 4B, an inking line is drawn on the upper portion J of the opening R. Drill a pilot hole for screwing, adjust the spacer 29 so that it is horizontal with the spacer 29 between the upper frame 1 and the upper part J of the opening R. At this time, the upper frame fixing metal fitting 16 is attached, and the upper frame 1 is inserted into the bolt 18 hanging downward from the upper frame fixing metal fitting 16 from below and tightened with a nut 19 to The attachment of the frame 1 is completed.

  Next, as a second process, a procedure for attaching the lower frame hanging jig 5 to the lower frame 3 will be described. As shown in FIGS. 1 and 2B, four lower frame hanging jigs are suspended at the four corners of the lower frame 3 in plan view. Although the jig 5 is attached (see FIG. 1), the upper suspension doors 4a, 4b, 4c are locked at the positions of the door tips and the bottom of the doors when the upper suspension doors 4a, 4b, 4c are placed in the lower frame 3. A lock seat 14 may be provided, and when the lock seat 14 is attached as shown in FIG. 1, an adjustment screw hole 23 b on the lower side of the lower frame attachment 8 is provided in the attachment screw hole 24 of the bar 7. The locking screw 13a is matched and fixed with the mounting screw 13a so that the abutting portion 12 of the lower frame mounting tool 8 is brought into contact with the upper end portion of the lock seat 14, and the lock seat 14 is fixed to the lock seat 14 by the lock seat fixing screw 13b. Together, it is screwed to the bottom U of the rail groove 15. On the other hand, when the lower frame hanging jig 5 is attached to a place where the lock seat 14 is not provided, the adjustment screw hole 23a on the upper side of the lower frame attachment 8 is aligned with the attachment screw hole 24 of the bar 7 and is screwed with the attachment screw 13a. The abutting portion 12 of the lower frame fixture 8 is abutted against the bottom U of the rail groove 15 of the lower frame 3 and is fixed with a fixing screw 13c.

  Next, as a third step, a procedure for attaching the lower frame hanging jig 5 to which the lower frame 3 is attached to the upper frame 1 will be described. As shown in FIG. 2 (c), there are four lower parts (only two are shown in the figure). The frame hanging jig 5 is lifted to lift the lower frame 3 from the gap G, and the locking portion 9 of the upper frame locking tool 6 is positioned above the guide rail 2, and then the lower frame 3 is lowered to lock the locking portion 9. The upper frame 1 is vertically locked to the guide rail 2 standing upright by the downward recessed portion P of the locking portion 9, and the lower frame 3 is suspended from the upper frame 1 by the lower frame lifting jig 5. The state is lowered. At this time, the positional relationship between the position of the guide rail 2 and the height of the rail groove 15 is on the same straight line Q in the height direction (see FIG. 3B), and the lower frame 3 is moved from the upper frame 1 to the lower frame. When suspended by the suspension jig 5, the upper suspension doors 4a, 4b, and 4c can be stored vertically without requiring adjustment of the attachment positions of the upper frame 1 and the lower frame 3.

  Next, as shown in FIG. 2 (d), after positioning the mortar 27 around the legs 22 of the lower frame 3 as the fourth step, the concrete 28 is applied to the entire lower part of the lower frame 3 and left for a while. When the concrete 28 is hardened, as shown in FIG. 2E, the lock seat fixing screw 13b and the fixing screw 13c are removed from the lower frame 3 and the lower frame hanging jig 5 and locked to the guide rail 2 as a fifth step. The upper frame locking tool 6 to be lifted and the lower frame hanging jig 5 are removed from the upper frame 1 and the lower frame 3, whereby the attachment of the upper frame 1 and the lower frame 3 to the opening R is completed. Since the lock seat fixing screw 13b is used to fix the lock seat 14 to the lower frame 3, the lock seat 14 is kept fixed to the lower frame 3 when the lower frame lifting jig 5 is removed. It is also possible to make the state once loosened and then tighten again after removing the lower frame hanging jig 5 from the lower frame 3.

Here, the number of lower frame hanging jigs 5 used in the construction procedure may be two or three. In the present embodiment, the lower frame 3 is suspended from the four corners of the upper frame 1 in plan view, but the lower frame hanging jig 5 is attached to the upper frame 1 at intervals in the longitudinal direction of the same guide rail 2, for example. Even if the lower frame 3 is suspended from the two guide rails 2 and 2 in parallel (positions orthogonal to the guide rail 2 and diagonal positions), the lower frame 3 is stably provided. Can be hung. About the number of the guide rails 2 of the upper frame 1, in this embodiment, although the thing of three is shown as a three-storied upper suspension door, for example, one, two, or four may be sufficient,
Similarly, the number of rail grooves 15 in the lower frame 3 corresponds to the number of upper suspension doors to be accommodated, and may be one, two, or four, for example.

  By providing a plurality of through holes in the vertical direction of the upper frame locking tool 6 or the vertical direction of the lower frame mounting tool 8, while also providing a plurality of through holes in the vertical direction at the upper end and the lower end of the bar 7, The length of the lower frame hanging jig 5 can be finely adjusted by screwing the bar 7 and the through holes of the upper frame locking tool 6 and the lower frame mounting tool 8 together.

  As long as the upper frame locking device 6 can detachably lock the guide rail 2, for example, the locking portion 9 is formed in an inverted L shape and is hooked on the guide rail 2 by a bent portion, or the locking portion 9 is engaged. The stop portion 9 may be formed in a T-shape, and a horizontal portion projecting on both sides may be spanned between the two guide rails 2 of the upper frame 1. In addition to the one that is locked to the guide rail 2, the upper frame locking tool 6 may be one that is screwed to the guide rail 2. Further, the upper frame locking tool 6 and the bar 7 may be attached with screws, and the lower frame mounting tool 8 may be attached to the locking claws 10a and 10b of the upper frame locking tool 6 of this embodiment. It may be locked to the bar 7 with a corresponding claw-shaped portion, and from this, it is not limited to this embodiment as long as it can be attached and detached.

  In this embodiment, the bar 7 and the lower frame fixture 8 are screwed with the mounting screws 13a at the construction site. For example, as shown in FIGS. A lock provided with a frame locking tool 6 and a lower frame mounting tool 8 is prepared, and the head is slightly lifted to the bottom U of the lock seat 14 and the rail groove 15 of the lower frame 3 so as not to be tightened. The seat fixing screw 13b and the fixing screw 13c are attached (see FIG. 4A), and the notch 26 of the lower frame fixture 8 is slid to the lock seat fixing screw 13b and the head of the fixing screw 13c. It is possible to proceed with the main construction by the procedure of attaching (see FIG. 4B). Moreover, the leg part 22 of the lower frame 3 should just be what can fix the lower frame 3 easily when the concrete 28 is hit, for example, it protruded from the lower part of the lower frame 3 toward the downward | lower direction. It may be simple.
