[0018] The attachment auxiliary material 2 preferably has a length dimension similar to the finding dimension of the inner periphery of the opening, and is preferably arranged so that no gap is generated between the outer periphery of the attachment auxiliary material 2 and the inner peripheral surface of the opening when the attachment auxiliary material 2 is arranged around the four sides of the opening. Note that the attachment auxiliary material 2 may be composed of a plurality of long members divided in the longitudinal direction.

[0019] The attachment auxiliary materials 21 and 22 fixed to the upper inner peripheral surface and the lower inner peripheral surface of the opening are arranged with the non-combustible material E sandwiched between them on the projected wall D1 of the steel material D and fixed by fixing means b1 such as drill screws. The attachment auxiliary materials 23 and 23 fixed to the left and right inner peripheral surfaces of the opening are arranged on the projected surface of the square upright A and fixed by fixing means b1 such as drill screws.

[0020] The frame members 1 (upper frame member 11, lower frame member 12, and vertical frame member 13) are made of a metal material such as an aluminum alloy, and have a frame body (upper frame body 111, lower frame body 121, and vertical frame body 113) and pressing edges 112, 122, 132, and are long members having the same cross-sectional shape on each side of the inner circumference of the opening.

[0021] The upper frame member 11, lower frame member 12, and left and right vertical frame members 13, 13 attached to the inner circumferential side of the attachment auxiliary member 2 and arranged around the opening have a glass holding groove on the inner circumference, and a setting block 125 is installed in the glass holding groove of the lower frame member 12, and a panel body 15 having fire resistance such as a fireproof glass is fitted therein, and a FIX window is provided on the indoor side of the curtain wall P.

[0022] Hereinafter, the attachment auxiliary member 2 and the frame member 1 forming the frame of the FIX window will be further described with reference to FIG. 3, taking the attachment auxiliary member 22 and the lower frame member 12 of the lower frame portion as an example. Since the attachment auxiliary member 21 and the upper frame member 11 of the upper frame portion and the attachment auxiliary member 23 and the vertical frame member 13 of the vertical frame portion have the same configuration, the description thereof will be omitted here.

[0023] The attachment auxiliary member 22 has a prospective wall 22a fixed to the inner circumference of the opening, an indoor finding wall 22b extending from the indoor side end of the prospective wall 22a to the inner circumference, and an outdoor finding wall 22b extending from the outdoor side end of the prospective wall 22a to the inner circumference, and two ribs 22c, 22c are formed along the longitudinal direction on the inner circumferential surface of the prospective wall 22a.

[0024] The attachment auxiliary member 22 is disposed on the inner circumferential surface of the non-combustible material E, and the prospective wall 22a is fixed to the inner circumferential surface (steel material D) of the opening by fixing means b1 such as a drill screw between the two ribs 22c, 22c at an appropriate position in the longitudinal direction. When the attachment auxiliary member 22 is formed of a plurality of members divided in the longitudinal direction, it is preferably arranged with a gap sufficient to absorb the elongation of the attachment auxiliary member 22 in case of fire between the adjacent members in the finding direction.

[0025] The lower frame member 12 has a lower frame body 121 disposed and fixed inside the inner circumference of the mounting auxiliary member 22, and a pressing edge 122 attached to the lower frame body 121.

[0026] The lower frame body 121 has a bottom wall portion 121a that constitutes a glass holding groove 12a for holding the panel body 15, an indoor finding wall 121b that extends in the inner circumferential direction from the outdoor side of the bottom wall portion 121a, a prospective wall 121c that extends in the outdoor direction from the inner circumferential end of the indoor finding wall 121b, and an outdoor finding wall 121d that extends in the outer circumferential direction from the outdoor side end of the prospective wall 121c. A first pressing edge engaging portion 121e that engages with the outdoor side end of the pressing edge 122 is provided on the upper surface of the bottom wall portion 121a, and a second pressing edge engaging portion 121f that engages with the lower surface of the pressing edge 122 is provided at the indoor side end of the bottom wall portion 121a.

[0027] The lower frame body 121 has the lower end of the outdoor finding wall 121d bent inward, and an auxiliary member mounting portion 12b having a substantially U-shaped cross-section that opens downward (in the outer circumferential direction) on the outdoor side of the bottom wall portion 121a is formed by the indoor finding wall 121b, the prospective wall 121c, and the outdoor finding wall 121d.

[0028] The lower frame body 121 is provided with an airtight material mounting portion 121g that protrudes inward in the upper (inner circumferential side) portion of the indoor finding wall 121b. Note that the lower frame body 121 may have marks or the like indicating positions for fixing fixing means b3 such as drill screws to the indoor finding wall 121b of the auxiliary member mounting portion 12b at appropriate positions in the longitudinal direction.

[0029] The dimension between the outdoor side surface of the indoor finding wall 121b and the lower end (the indoor side end bent inward) of the outdoor finding wall 121d of the lower frame body 121 is larger than the dimension between the outer side surfaces of the indoor and outdoor finding walls 22b, 22b of the mounting auxiliary member 22, and the indoor and outdoor finding walls 22b, 22b of the mounting auxiliary member 22 can be covered from the inner circumferential side and slidably fitted in the inner and outer circumferential directions.

[0030] By disposing a spacer 124 with an appropriate thickness dimension between the bottom wall portion 121a of the lower frame body 121 disposed on the inner circumference of the attachment auxiliary material 22 and the inner peripheral surface of the opening, the height position (search direction position) of the lower frame body 121 can be set, and the load when the panel body 15 is fitted can be borne.

[0031] The pressing edge 122 includes a glass holding wall 122a that forms the indoor side wall of the glass holding groove 12a, an engaging wall 122b that extends outward from a position below (outer peripheral side) the center in the height (inner and outer circumferences) direction on the outdoor side surface of the glass holding wall 122a, an inclined wall 122c that extends outward from the outdoor side of the engaging wall 122b and inclines downward (outer peripheral side), and an engaging portion 122d that extends outward from the outdoor side end of the inclined wall 122c.

[0032] The pressing edge 122 is attached to the lower frame body 121 by engaging the engaging portion 122d with the first pressing edge engaging portion 121e of the lower frame body 121 from the indoor side and locking the corner portion 122e between the inclined wall 122c and the lower frame body 121 with the second pressing edge engaging portion 121f of the lower frame body 121 at the lower surface (outer peripheral surface) of the engaging wall 122b. Further, the engaging portion 122d engaged with the first pressing edge engaging portion 121e and the bottom wall portion 121a of the lower frame body 121 may be fastened and fixed to the spacer 124 by fixing means b4 such as screws from the inner peripheral side. Note that the engaging wall 122b of the pressing edge 122 may be provided with a corner portion 122e formed at a right angle to the continuous portion with the inclined wall 122c by bending the outdoor side end downward (outer peripheral side) and then extending the inclined wall 122c.

[0033] The pressing edge 122 attached to the lower frame body 121 covers the indoor side of the bottom wall portion 121a of the lower frame body 121 in a state where the lower end (outer peripheral end) of the glass holding wall 122a is separated from the inner peripheral surface of the opening.

[0034] A setting block 125 is disposed in the glass holding groove 12a of the lower frame material 12 fixed to the lower inner peripheral surface of the opening, and the panel body 15 is held. The configurations of the attachment auxiliary material 2 and the frame material 1 that form the frame of the FIX window have been described above.

[0035] (Installation Procedure of FIX Window) The installation of the FIX window can be carried out according to the following procedure examples. Step 1: Installation of the mounting auxiliary materials for the lower frame and the upper frame Step 2: Installation of the mounting auxiliary materials for the vertical frames Step 3: Installation of the lower frame body of the lower frame material Step 4: Installation of the vertical frame body of one side vertical frame material Step 5: Installation of the upper frame body of the upper frame material and the vertical frame body of the other side vertical frame material Step 6: Installation of the glass panel and the pressing edge The following will explain each step.

[0036] Step 1: Installation of the mounting auxiliary materials for the lower frame and the upper frame Attach the lower mounting auxiliary material 22 to the lower inner peripheral surface of the opening with drill screws b1, and attach the upper mounting auxiliary material 21 to the upper inner peripheral surface of the opening with drill screws b1. When the mounting auxiliary materials 21 and 22 are composed of a plurality of members divided in the longitudinal (left - right) direction, align the outer peripheral side ends of the members with the left - right inner peripheral surfaces of the opening and attach them so that a gap is formed between the members.

[0037] Step 2: Installation of the mounting auxiliary materials for the vertical frames Attach the left and right mounting auxiliary materials 23, 23 to the left - right inner peripheral surfaces of the opening with drill screws b1. When the mounting auxiliary material 23 is composed of a plurality of members divided in the longitudinal (up - down) direction, align the outer peripheral side end of the lower member of the mounting auxiliary material 23 with the upper surface of the mounting auxiliary material 22 of the lower frame, and align the outer peripheral side end of the upper member of the mounting auxiliary material 23 with the upper surface of the mounting auxiliary material 21 of the upper frame, and attach them so that a gap is formed between the members of the mounting auxiliary material 23.

[0038] Step 3: Installation of the lower frame body of the lower frame material Place the lower frame body 121 of the lower frame material 12 on the lower inner peripheral surface of the opening so that the mounting auxiliary material 22 is inserted into the auxiliary material mounting portion 12b, and fix the indoor - side finding wall 121b of the lower frame body 121 and the indoor - side finding wall 22b of the mounting auxiliary material 22 with drill screws b3. When fixing the lower frame body 121 with the drill screw b3, a spacer 124 may be arranged below the bottom wall portion 121a of the lower frame body 121 to position the height position of the lower frame body 121.

[0039] Procedure 4: Attachment of the vertical frame body of the vertical frame member on one side Arrange the vertical frame body 131 of the vertical frame member 13 on one side on the vertical inner peripheral surface of the opening so that the attachment auxiliary member 23 is inserted into the auxiliary member attachment portion 13b, and fix the indoor side finding wall 131b of the vertical frame body 131 and the indoor side finding wall 23b of the attachment auxiliary member 23 with the drill screw b3. When attaching the vertical frame body 131, arrange the lower end surface of the vertical frame body 131 in alignment with the lower frame corner piece arranged at the end of the lower frame member 12.

[0040] Procedure 5: Attachment of the upper frame body of the upper frame member and the vertical frame body of the vertical frame member on the other side While inserting the attachment auxiliary member 21 into the auxiliary member attachment portion 11b of the upper frame body 111 of the upper frame member 11, move the upper frame body 111 so that one end on one side enters between the upper end of the vertical frame body 131 on one side and the upper inner peripheral surface of the opening, and finally temporarily arrange it along the upper inner peripheral surface. Next, while inserting the attachment auxiliary member 23 into the auxiliary member attachment portion 13b of the vertical frame body 131 on the other side, move the vertical frame body 131 on the other side toward the vertical inner peripheral surface so that it enters between the upper frame body 111 and the lower frame body 121, and finally temporarily install it along the vertical inner peripheral surface.

[0041] With the upper frame body 111 and the vertical frame body 131 on the other side temporarily installed, install the upper and lower ends of the left and right vertical frame bodies 131 in alignment with the upper frame corner pieces arranged at both ends of the upper frame body 111 and the lower frame corner pieces arranged at both ends of the lower frame body 121 so that there are no gaps between the upper and lower ends of the left and right vertical frame bodies 131 and the upper frame body 111 and the lower frame body 121.

[0042] When it becomes a four-sided frame, fix the finding wall 111b on the indoor side of the upper frame body 111 and the finding wall 21b on the indoor side of the attachment auxiliary material 21 with a drill screw b3, and fix the finding wall 131b on the indoor side of the other vertical frame body 131 and the finding wall 23b on the indoor side of the attachment auxiliary material 23 with a drill screw b3. In addition, an airtight material such as a bead material should be attached in advance to the airtight material attachment part 121g of the lower frame body 121 (and the upper frame body 111 and the vertical frame body 131).

[0043] Procedure 6: Installation of glass panel and attachment of edge trim Attach the edge trim 122 to the lower frame body 121 fixed to the inner circumference of the opening and fix it with fixing means b4 such as screws. Then, install the panel body 15 inside the frame through the setting block 125.

[0044] After installing the panel body 15, attach the edge trims 112 and 132 to the upper frame body 111 and the left and right vertical frame bodies 131, and fit the retrofitted bead between the panel body 15 and the edge trims 112, 122, and 132 to complete the construction. The construction procedure of the FIX window has been described above.

[0045] (Effect of the opening device of this embodiment) As described above, the opening device of this embodiment arranges the attachment auxiliary material on the inner circumference of the opening, and fits and arranges the frame body so as to be slidable in the inner and outer circumferential directions so as to cover the attachment auxiliary material. Thus, the position of the frame body can be adjusted according to the dimensional error of the opening, etc., and the workability can be improved.

[0046] The opening device of this embodiment forms the attachment auxiliary material with the finding wall and the finding walls on the indoor side and the outdoor side, and fits and attaches the finding wall of the attachment auxiliary material to the auxiliary material attachment part of the frame body. Therefore, the fixing part of the attachment auxiliary material that supports the frame material to the opening can be protected, and the fireproof performance can be improved. In addition, by covering the indoor finding wall of the attachment auxiliary material from the indoor side with the edge trim, the attachment auxiliary material can be further protected, and the fireproof performance can be further improved.

[0047] Since the opening device of the present embodiment can arrange the mounting auxiliary material and the glass holding groove in the looking-in direction, the finding of the frame material can be reduced, and by mounting the indoor-side finding wall of the pressing edge mounted on the indoor side of the frame body with a gap with respect to the inner peripheral surface of the opening, a sense of depth can be given to the frame material, and the design property can be improved.

[0048] In the opening device of the present embodiment, the frame body and the pressing edge are engaged in the indoor-outdoor direction by the first pressing edge engaging portion provided on the bottom wall portion of the frame body and the engaging portion provided at the outdoor-side end of the pressing edge, and the second engaging portion provided at the indoor-side end of the frame body and the corner portion formed on the lower surface of the pressing edge are engaged in the inner-outer peripheral direction. Therefore, it can be firmly attached in both the finding direction and the looking-in direction.

[0049] Further, since the engaging portion of the pressing edge is provided via the inclined portion from the engaging wall, the engaging portion of the pressing edge can be easily inserted into the concave portion between the first pressing edge engaging portion and the second pressing edge engaging portion provided on the frame body, and the engagement from the indoor side with respect to the first pressing edge engaging portion is easy.

[0050] -Other Embodiments- The fixing of the mounting auxiliary material 22 and the lower frame body 121 is not limited to drill screws. For example, screw holes may be formed in the finding wall 22b of the mounting auxiliary material 22 and the indoor-side finding wall 121b of the lower frame body 121, and they may be fixed by fixing means such as screws through the screw holes. In that case, the screw holes formed in the mounting auxiliary material 22 or the lower frame body 121 may be formed as long holes so that the lower frame body 121 can be fixed to the mounting auxiliary material 22 in a vertically position-adjustable manner.

[0051] The opening to which the opening device is attached is not limited to the opening formed on the indoor side of the curtain wall. The opening device may be, for example, an inner window constructed in the opening on the indoor side of an existing FIX window arranged on the outdoor side. In addition, the sealing material for sealing between each frame member of the opening device and the panel body 15 is not limited to a dry airtight material such as a bead material, and may be a wet seal by filling the sealing material after arranging a backup material.

[0052] Furthermore, the materials of the upper frame member, lower frame member, and vertical frame member of the opening device are not particularly limited, and may be metal materials such as stainless steel or aluminum, or other flame-retardant materials.

[0053] The above embodiments do not limit the invention described in the claims, and it goes without saying that they are treated as examples.
