Description

[Technical field]

[0001] The present invention relates to a window connecting structure in which a vertical frame of a window is attached to a mounting material by an anchor. [Background technology]

[0002] In horizontally connected windows (horizontal connected windows), the window sections are installed side by side in the left-right direction, and the left and right window sections adjacent in the left-right direction are connected by a window section connecting structure. In the left and right window sections, the vertical frames of each window section are attached to the mounting material by anchors, and the vertical frames and window sections are held by the mounting material. A conventionally known window section connecting structure of this type has an iron anchor provided between the vertical frame and mullion of the window section (see Patent Document 1).

[0003] In the conventional window connection structure described in Patent Document 1, the upright has an interior upright member, which is a mounting member provided on the interior side, and an exterior upright member provided on the exterior side. The vertical frame and the upright are fixed by an anchor, and the vertical frame is attached to the interior upright member of the upright. However, when fixing the anchor to the interior upright member, one side of the angle bar is welded to the second locking part of the anchor, and the other side of the angle bar is welded to the interior upright member. Thus, in the conventional window connection structure, when attaching the vertical frames of the left and right window sections to the interior upright members, it is necessary to fix the anchor to the interior upright member by welding at two points via the angle bar for each of the left and right window sections. Therefore, it is troublesome to attach the vertical frame to the interior upright member, and there is a concern that this will affect the workability of the window connection structure.

[0028] FIG. 4 is a diagram showing the anchor 70 of the first embodiment, and shows one anchor 70 viewed from three directions. FIG. 4A shows the anchor 70 viewed from the indoor side. FIG. 4B shows the anchor 70 viewed from the direction of the arrow X1 in FIG. 4A, and shows the anchor 70 viewed from above, similar to FIG. 3. FIG. 4C shows the anchor 70 viewed from the direction of the arrow X2 in FIG. 4A, and shows the anchor 70 viewed from one side in the left-right direction S. FIG. 5 is a diagram showing the arrangement of two anchors 70 when the vertical frames 7 of the left and right window parts 2 of the first embodiment are attached to the mounting material 20 by the anchors 70, respectively, and one of the two anchors 70 is shown by a chain line. FIG. 5A shows the anchor 70 viewed from the indoor side, similar to FIG. 4A. FIG. 5B shows the anchor 70 viewed from the direction of the arrow X3 in FIG. 5A, and shows the anchor 70 viewed from above, similar to FIG. 3 and FIG. 4B.

[0029] As shown in the figure, the anchor 70 has a plate-shaped fixing portion 71, a restricting portion 72 that restricts rotation of the anchor 70, and a clamping portion 73 that protrudes from the fixing portion 71 toward the vertical frame 7. The fixing portion 71 is fixed to the mounting material 20 by a fixing device 8F, and the anchor 70 is attached to the mounting material 20 by fixing the fixing portion 71 to the mounting material 20. The fixing device 8F is detachably attached to the mounting material 20, and detachably fixes the fixing portion 71 and the anchor 70 to the mounting material 20.

[0030] In each of the anchors 70, the fixing portion 71 is located on the indoor side of the indoor surface portion 23 of the mounting material 20 and is arranged along the left-right direction S. The fixing device 8F is attached to the indoor surface portion 23 of the mounting material 20 from the indoor side of the fixing portion 71 by inserting it through an insertion hole 71A formed in the fixing portion 71. The insertion hole 71A is an elongated hole extending in the up-down direction R, and the dimension (length) of the insertion hole 71A in the up-down direction R is larger than the dimension (width) of the insertion hole 71A in the left-right direction S. The fixing portion 71 and the anchor 70 are fixed to the indoor surface portion 23 of the mounting material 20 by the fixing device 8F and are held on the indoor surface portion 23 of the mounting material 20.

When the fixing portion 71 of the anchor 70 is fixed to the indoor surface portion 23 of the mounting material 20 by the fixing device 8F, the abutment of the restricting portion 72 against the fixing portion 71 restricts the rotation of the fixing portion 71 and the anchor 70.

[0032] The clamping portion 73 of the anchor 70 clamps the holding portion 7D (see FIG. 3) of the vertical frame 7 and is fixed to the holding portion 7D. The holding portion 7D is inserted into the clamping portion 73 from the indoor side and is clamped by the clamping portion 73. As a result, the holding portion 7D fits into the clamping portion 73, and the clamping portion 73 is engaged with the holding portion 7D. Furthermore, the holding portion 7D and the vertical frame 7 are held by the clamping portion 73 and attached to the indoor surface portion 23 of the mounting material 20 via the anchor 70.

[0033] The clamping portion 73 of the anchor 70 has a first piece 74 located on one side of the holding portion 7D and a second piece 75 located on the other side (opposite side of the first piece 74) of the holding portion 7D, and the first piece 74 and the second piece 75 clamp the holding portion 7D. The first piece 74 and the second piece 75 are located on opposite sides of the holding portion 7D, with the holding portion 7D sandwiched between them. The first piece 74, the second piece 75, and the clamping portion 73 protrude from the fixing portion 71 to one side in the indoor / outdoor direction T, and the first piece 74 and the second piece 75 are arranged along the indoor / outdoor direction T.

[0034] The holding portion 7D of the vertical frame 7 is sandwiched between the first and second pieces 74 and 75 in a state where it is inserted from the tip side of each of the first and second pieces 74 and 75 toward the base end side thereof (the portion sandwiched between the first and second pieces 74 and 75), and is held by the first and second pieces 74 and 75. The tip of each of the first and second pieces 74 and 75 is the front end (point) in the protruding direction of each of the first and second pieces 74 and 75. The base end of each of the first and second pieces 74 and 75 is the rear end in the protruding direction of each of the first and second pieces 74 and 75, and is located on the opposite side of the tip in the protruding direction of the first and second pieces 74 and 75, and is connected to the fixing portion 71.

[0035] The first arm 74 is located on one side of the second arm 75 and the holding portion 7D in the left-right direction S, and the second arm 75 is located on the other side of the first arm 74 and the holding portion 7D in the left-right direction S. The first arm 74, the second arm 75, and the clamping portion 73 protrude from the fixing portion 71 toward the indoor side, and the area between the first arm 74 and the second arm 75 is open toward the indoor side. The first arm 74 and the second arm 75 are provided at positions offset from each other in the longitudinal direction of the vertical frame 7, and are disposed at different positions from each other in the longitudinal direction of the vertical frame 7. The first arm 74 and the second arm 75 each abut against the holding portion 7D of the vertical frame 7, and clamp the holding portion 7D from both sides in the left-right direction S.

[0036] At least one (one or more) of the first piece 74 and the second piece 75 is provided on the clamping portion 73, and at least two (two or more) of the other of the first piece 74 and the second piece 75 are provided on the clamping portion 73. At least one (either one or both) of the first piece 74 and the second piece 75 has a protrusion 76 that abuts against the holding portion 7D of the vertical frame 7, and abuts against the holding portion 7D only by the protrusion 76, thereby clamping the holding portion 7D by the protrusion 76. The protrusion 76 is formed on a portion of at least one of the first piece 74 and the second piece 75 that faces the holding portion 7D, and protrudes toward the holding portion 7D.

[0037] Here, in the left-right direction S, the first piece 74 is located on the outer side (the mounting material 20 side) of the window portion 2 with respect to the second piece 75 and the holding portion 7D, and the second piece 75 is located on the inner side (the opening 4A side of the frame body 4) of the window portion 2 with respect to the first piece 74 and the holding portion 7D. In addition, one first piece 74 is provided in the sandwiching portion 73, and two second pieces 75 are provided in the sandwiching portion 73. The two second pieces 75 are provided on both sides (upper and lower sides) of the first piece 74 in the up-down direction R. Of the first piece 74 and the second piece 75, the first piece 74 does not have a protrusion 76, and only the second piece 75 has a protrusion 76. The protrusion 76 is provided only in the second piece 75, is formed in each of the second pieces 75, and protrudes toward the outer side of the window portion 2 in the left-right direction S. The restricting portion 72 is formed contiguous with the second arm 75 and protrudes from the second arm 75 .

[0038] One of the first piece 74 and the second piece 75 has a positioning portion 77 for positioning the holding portion 7D, and the other of the first piece 74 and the second piece 75 has a pressing portion 78 for pressing the holding portion 7D. When the clamping portion 73 of the anchor 70 is viewed in the longitudinal direction of the vertical frame 7 (see Figs. 4B and 5B), the first piece 74 and the second piece 75 are formed so as to gradually separate from the base end side located on the side of the respective fixing portions 71 toward the tip end side. The first piece 74 and the second piece 75 are separated from each other in the left-right direction S, and the separation is greater on the tip end side than on the base end side. Accordingly, one of the first piece 74 and the second piece 75 is inclined with respect to the other of the first piece 74 and the second piece 75.

[0039] Here, the first piece 74 has a positioning portion 77, and the second piece 75 has a pressing portion 78. The positioning portion 77 is a flat portion (positioning surface portion) formed in a flat shape, and is provided in a portion of the first piece 74 facing the holding portion 7D, and is arranged along the indoor-outdoor direction T. The positioning portion 77 is also arranged toward the inner side of the window part 2 in the left-right direction S, and abuts against the holding portion 7D of the vertical frame 7 to position the holding portion 7D. The positioning portion 77 positions the position of the holding portion 7D in the left-right direction S, and the holding portion 7D and the vertical frame 7 are positioned at a predetermined position in the left-right direction S by the positioning portion 77. The pressing portion 78 is a protrusion 76 of the second piece 75 that abuts against the holding portion 7D, and presses the holding portion 7D abutting against the positioning portion 77, pressing the holding portion 7D against the positioning portion 77.

[0040] When the clamping portion 73 of the anchor 70 is viewed in the longitudinal direction of the vertical frame 7, the distance between the first arm 74 and the second arm 75 gradually increases from the base end side toward the tip end side, and is wider at the tip end side than at the base end side. Here, the base end side of the first arm 74 and the second arm 75 is the outdoor side, and the tip end side of the first arm 74 and the second arm 75 is the indoor side. The second arm 75 is inclined with respect to the first arm 74, the positioning portion 77, and the indoor / outdoor direction T. The second arm 75 is inclined with respect to the first arm 74 and the positioning portion 77 in a direction away from the first arm 74 and the positioning portion 77 from the base end side (outdoor side) toward the tip end side (indoor side), and is gradually away from the first arm 74 and the positioning portion 77 from the base end side toward the tip end side.

[0041] 6 to 10 are diagrams showing a construction procedure (first construction procedure) of the window section connecting structure 3 of the first embodiment. As shown in the figure, before constructing the window connection structure 3, the mounting material 20 is installed in advance in the opening 12 of the building 10, and the retaining material 30 is attached to the mounting material 20 (see FIG. 6). In addition, the retaining parts 7D of the vertical frames 7 of the left and right window parts 2 are sandwiched between the clamping parts 73 of separate anchors 70, and the clamping parts 73 of the anchors 70 are fixed to the retaining parts 7D, respectively. In this state, the left and right window parts 2 are inserted into the opening 12 of the building 10, and the vertical frames 7 of the left and right window parts 2 are arranged on both sides of the left and right direction S of the mounting material 20 (see FIG. 7). At that time, the vertical frames 7 of the left and right window parts 2 are respectively arranged on the indoor side of the outdoor-side retaining wall 32 of the retaining material 30, and each of the fixing parts 71 of the anchor 70 is arranged on the indoor side of the indoor surface part 23 of the mounting material 20. Next, each of the fixing parts 71 of the anchor 70 is fixed to the indoor surface part 23 of the mounting material 20 by the fixing device 8F (see FIG. 8).

[0042] Next, the connection member 40 is placed on the mounting material 20 and the vertical frames 7 of the left and right window sections 2 on the indoor side, and the middle part 41 of the connection member 40 is fixed to the indoor surface part 23 of the mounting material 20 by the fasteners 8B. Also, the vertical frames 7 (indoor side facing parts 7C) of the left and right window sections 2 are fixed to the indoor side retaining wall 42 of the connection member 40 by the fasteners 8C, respectively (see FIG. 9). As a result, the retaining part 7D of the vertical frame 7 is sandwiched and held between the clamping part 73 of the anchor 70 and the indoor side retaining wall 42 of the connection member 40 in the indoor / outdoor direction T. Next, the fireproof covering 50 is placed on the indoor side of the connection member 40, and the fireproof covering 50 is fixed to the mounting material 20 by the fasteners 8D (see FIG. 10). In this state, the connection member 40 and the fireproof covering 50 are covered from the indoor side by the cover 60, and the cover 60 is fixed to the connection member 40 by the left and right fasteners 8E (see FIG. 3). In this manner, the construction of the window section connecting structure 3 is completed.

[0043] FIG. 11 is a diagram showing a part of another construction procedure (second construction procedure) of the window section connecting structure 3 of the first embodiment. As shown in the figure, before the clamping portion 73 of the anchor 70 is fixed to the holding portion 7D of the vertical frame 7, the fixing portion 71 of the anchor 70 is fixed to the indoor surface portion 23 of the mounting material 20 by the fixing device 8F. Next, the left and right window sections 2 are inserted into the opening 12 of the building 10, and the vertical frames 7 of the left and right window sections 2 are arranged on both sides of the mounting material 20 in the left-right direction S. At that time, the vertical frames 7 of the left and right window sections 2 are respectively arranged on the indoor side of the outdoor side holding wall 32 of the holding material 30, and the holding portion 7D of the vertical frames 7 of the left and right window sections 2 are clamped by the clamping portion 73 of the anchor 70. As a result, the holding portion 7D of the vertical frame 7 is fixed to the clamping portion 73 of the anchor 70. Next, the window section connecting structure 3 is constructed in the same construction procedure as the construction procedure shown in Figures 8 to 10, and the construction of the window section connecting structure 3 is completed.

[0044] In the window connecting structure 3 of the first embodiment described above, the vertical frames 7 of the left and right windows 2 can be easily attached to the mounting material 20 using the anchors 70, improving the ease of construction of the window connecting structure 3. Also, depending on the construction aspect of the window connecting structure 3, the construction procedure for the window connecting structure 3 can be selected from two construction procedures (first construction procedure, second construction procedure), making it easy to construct the window connecting structure 3.

[0045] The first piece 74 and the second piece 75 of the clamping portion 73 of the anchor 70 allow the clamping portion 73 of the anchor 70 to be easily fixed to the holding portion 7D of the vertical frame 7. By gradually separating the first piece 74 and the second piece 75 from their respective base ends toward their tip ends, the holding portion 7D of the vertical frame 7 can be easily inserted into a location between the first piece 74 and the second piece 75, making it easier to push the holding portion 7D of the vertical frame 7 into the clamping portion 73. Therefore, the holding portion 7D of the vertical frame 7 can be easily positioned at a position where it is clamped by the first piece 74 and the second piece 75, and the clamping portion 73 of the anchor 70 can be easily fixed to the holding portion 7D of the vertical frame 7.

[0046] The protrusion 76 provided on the second arm 75 allows the holding portion 7D of the vertical frame 7 to be securely fitted between the first arm 74 and the second arm 75, so that the holding portion 7D of the vertical frame 7 can be stably held by the clamping portion 73 of the anchor 70. In addition, the protrusion 76 prevents the holding portion 7D of the vertical frame 7 from getting caught on the edges of the first arm 74 and the second arm 75, so that the holding portion 7D of the vertical frame 7 can be easily held by the first arm 74 and the second arm 75.

[0047] The positioning portion 77 provided on the first piece 74 positions the holding portion 7D of the vertical frame 7, making it possible to accurately position the vertical frame 7 and the window portion 2. Furthermore, because the pressing portion 78 of the second piece 75 is a protrusion 76, the holding portion 7D of the vertical frame 7 can be stably held in the clamping portion 73 of the anchor 70 with the holding portion 7D in contact with the positioning portion 77.

[0048] At least two first pieces 74 and at least one second piece 75 may be provided on the clamping portion 73 of the anchor 70. Also, two or more of each of the first pieces 74 and the second pieces 75 may be provided. The positioning portion 77 may be provided on the second piece 75, and the pressing portion 78 may be provided on the first piece 74. Therefore, the protrusion 76 may be provided on the first piece 74. On the other hand, when the positioning portion 77 is not necessary, the protrusion 76 may be provided on both the first piece 74 and the second piece 75.

[0049] Next, other embodiments of the window connection structure 3 will be described.
