The engaging portion 6 and the space portion 7 are arranged in the indoor / outdoor direction, and the vertical frame 3 is fixed to the vertical member 2 on the indoor side of the engaging portion 6 and the space portion 7.

  The vertical member 2 is an extruded shape of an aluminum alloy extending in the vertical direction. As shown in FIGS. 1 and 3, the vertical frame 3 is attached to the inner peripheral side, and the outer peripheral side is the inner periphery of the column 1a or the vertical 1g. Screwed in contact with the side. As shown in FIG. 4, the longitudinal dimension of the vertical member 2 is substantially equal to the vertical width of the inter-column part Z1 and extends from the upper end of the upper horizontal frame 11 to the lower end of the lower horizontal frame 12. As shown in FIG. 5, the vertical member 2 includes a vertical member body 2 a that covers the inner peripheral side surface of the pillar 1 a or the vertical 1 g, and a latch that extends from the outdoor end of the vertical member body 2 a toward the outer peripheral side. It has a piece 2b. The vertical member main body 2a is formed with an engaging recess 2c recessed in the outer peripheral side along the longitudinal direction slightly outside the center in the indoor / outdoor direction. A screw hole 2d for attaching the vertical frame 3 is provided on the indoor side with a space from the engagement recess 2c. Also, screw holes 2e for fixing to the pillar 1a or the vertical 1g are provided at two locations on the outdoor side of the engagement recess 2c and on the indoor side of the screw hole 2d. The locking piece 2b is positioned when the opening construction material is fitted into the inner periphery of the interspace portion Z1 by the indoor side surface coming into contact with the outdoor side surface of the column 1a or the vertical 1g.

  The vertical frame 3 is an extruded shape of an aluminum alloy extending in the vertical direction. As shown in FIGS. 1 and 3, the vertical frame 3 holds the panel 4 on the inner peripheral side and is fixed to the vertical member 2 on the outer peripheral side. As shown in FIG. 4, the upper end of the vertical frame 3 is positioned downward from the upper end of the vertical member 2 by the size of the upper horizontal frame 11, and the lower end is the lower horizontal frame 12 from the lower end of the vertical member 2. Therefore, the longitudinal frame 3 is shorter than the longitudinal member 2 in the longitudinal direction. And the width | variety inside and outside of the vertical frame 3 is shorter than the width | variety between the screw holes 2e and 2e provided in the vertical material 2, and as shown in FIG. 5, the vertical frame main body 3a contact | abutted to the vertical material 2, and a vertical frame It has the panel holding piece 3b extended toward the inner peripheral side from the outdoor side edge part of the main body 3a. A tight material 8 is attached between the panel holding piece 3 b and the panel 4 on the indoor side. The vertical frame main body 3a is provided with an engaging convex portion 3c that protrudes toward the outer peripheral side at a position facing the engaging concave portion 2c of the vertical member 2 along the longitudinal direction. The engaging convex portion 3 c constitutes an engaging portion 6 together with the engaging concave portion 2 c of the vertical member 2, and the engaging portion 6 enables positioning of the vertical member 2 and the vertical frame 3. Further, the vertical frame body 3a is provided with a groove portion 3d which is recessed on the inner peripheral side adjacent to the indoor side of the engaging convex portion 3c. The groove 3d forms a space 7 together with the longitudinal member body 2a. When rainwater or the like enters between the vertical member 2 and the vertical frame 3 from the outside, it falls down through the space portion 7, and therefore it is possible to prevent the space portion 7 from entering the room. The space 7 may be filled with a water stop material. In addition, since it can stop also by the unevenness | corrugation of the engaging part 6, it can stop still more reliably because the engaging part 6 and the space part 7 are located in the indoor / outdoor direction. A pressing edge locking portion 3e is formed from the bottom of the groove portion 3d toward the inner peripheral side. The pressing edge locking portion 3e has a middle portion that is bent toward the indoor side to form a concave portion that opens to the indoor side together with the inner peripheral side of the groove portion 3d, and an end portion of a side wall 5b of the pressing edge 5 to be described later can be inserted. On the indoor side of the groove 3d, a screw hole 3f for fixing the vertical frame 3 to the vertical member 2 is provided at a position facing the screw hole 2d of the vertical member 2. Since the screw holes 2d and 3f are provided on the indoor side from the engaging portion 6 and the space portion 7, rainwater or the like does not enter from the screw holes 2d and 3f. Further, a push-edge locking portion 3g extending toward the inner peripheral side is formed at the indoor side end of the vertical frame main body 3a, and the push-lock locking portion 3g, together with the press-lock locking portion 3e formed in the groove 3d, The pressing edge 5 is locked.

  The panel 4 is fitted from the indoor side to the inner periphery of a frame constituted by the upper and lower horizontal frames 11 and 12 and the left and right vertical members 2 and the vertical frame 3, the panel holding piece 3 b on the outdoor side and the ledge on the indoor side. By being supported by 5, the left and right edge portions are sandwiched between the vertical frame 3 and the pressing edge 5.

  The pressing edge 5 is a resin member extending along the longitudinal direction of the vertical frame 3, and has a U-shape in plan view by a finding surface 5 a and side walls 5 b and 5 d extending from both ends of the finding surface 5 a, and has an opening. It is attached to the vertical frame 3 toward the outdoor side. The side wall 5b on the outer peripheral side is recessed at the corner with the finding surface 5a to form a locked portion 5c, and the end is locked to the push-edge locking portion 3e on the outdoor side. The part 5c is attached to the vertical frame 3 while being locked to the indoor edge pressing part 3g. The inner peripheral side wall 5 d is shorter in the indoor / outdoor direction than the outer peripheral side wall 5 b, and the tight material 9 is inserted between the end portion and the panel 4.

Next, the construction procedure of the main part of the opening part building material of this invention is demonstrated.
When it is necessary to match the lengths of the vertical member 2 and the vertical frame 3 to the height of the inter-space portion Z1, first, the vertical member 2 and the vertical frame 3 are trimmed. The vertical member 2 is trimmed to the height of the interspace portion Z1, and the vertical frame 3 is trimmed shorter than the vertical member 2 in consideration of the widths of the upper and lower horizontal frames 11 and 12 attached to the vertical member 2. And it positions so that the engagement convex part 3c of the vertical frame 3 may be fitted in the engagement concave part 2c of the vertical member 2, and the vertical frame fixing screw 10 is inserted into the screw holes 3f and 2d from the inner peripheral side. A vertical frame 3 is attached to 2. Next, the upper and lower horizontal frames 11, 12 and the left and right vertical members 2 and 3 are fixed in a frame. The panel 4 is put in the frame, and the pressing edge 5 is fitted into the vertical frame 3 from the indoor side, and then the tight material 9 is inserted between the panel 4 and the pressing edge 5 so that the panel 4 is fixed in the frame, and the opening portion Building materials are completed. When this opening building material is fitted into the space part Z1 from the outside, the vertical member 2 and the vertical frame 3 are positioned with respect to the pillar 1a and the vertical 1g by the locking piece 2b of the vertical member 2, and the screw of the vertical member 2 By fixing to the pillar 1a and the vertical 1g in the hole 2e, the opening building material is attached to the balustrade part Z1.

According to the opening construction material configured in this way, since the vertical member 2 and the vertical frame 3 are separate bodies, it is only necessary to cut and attach each member even when cutting is necessary, so that the workability is improved. Excellent. Since the engaging part 6 for positioning and the space part 7 for water stop are provided between the vertical member 2 and the vertical frame 3, it is more excellent in workability and has a good water stop.
Further, since the vertical frame 3 is fixed to the vertical member 2 on the indoor side of the engaging portion 6 and the space portion 7, there is no possibility that rainwater or the like enters from the screw holes 2d and 3f. Since the engaging part 6 is comprised by the engaging recessed part 2c of the vertical member 2, and the engaging convex part 3c of the vertical frame 3, it also has the effect of water stop. And since the engaging part 6 and the space part 7 are located in the indoor / outdoor direction, water can be reliably stopped indoors and outdoors.

  The present invention is not limited to the above-described embodiment, and can be changed without departing from the gist of the present invention. The present invention is not limited to the interspace provided in the simple structure, and can be widely applied to openings of buildings and structures. It is.
