Description

【Technical Field】 【0001】 The present invention relates to a sash. 【Background Art】 【0002】 A sash is attached to a building opening, and is known to have a panel in a frame body connecting vertical posts and upper, lower, and horizontal frames. 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0003】 There was a concern that such a sash might cause deformation of the vertical post due to thermal expansion and contraction after the sash was installed. Therefore, prevention of deformation of the vertical post caused by thermal expansion and contraction has been demanded. 【Means for Solving the Problems】 【0004】 In order to solve the above problems, the sash according to claim 1 includes a vertical post, a horizontal frame, and a vertical post reinforcing member. The vertical post and the horizontal frame They are connected support the panel, and an anchor attached to the outer periphery of the horizontal frame at a predetermined pitch and the building body are fixed via a welding material. The vertical post reinforcing member has a frame side member and a connecting member, and is provided at positions near the vertical post of the left and right horizontal frames of the vertical post respectively. The frame side member is fixed with screws from the inner peripheral side of the panel opening of the horizontal frame, and the connecting member is fixed via a welding material to the building body. The frame side member and the connecting member are connected so as to be relatively movable in the vertical direction. 【Effects of the Invention】 【0005】 With the above-described configuration, the present invention can prevent deformation of the vertical post caused by thermal expansion and contraction. 【Brief Description of the Drawings】 【0006】 [Figure 1] It is an overall front schematic view of the sash, as viewed from the indoor side. [Figure 2]The mounting structure for the mullion reinforcing member is shown, with (a) being an enlarged front view with a portion of the upper horizontal frame cut out, and (b) being a cross-sectional view of (a) from (b) to (b). [Figure 3] This figure shows the state in which deformation of the mullions due to thermal expansion and contraction is prevented. [Figure 4] This diagram illustrates the structure of the mullion reinforcing member; (a) is a perspective view, and (b) is an exploded perspective view. [Modes for carrying out the invention] 【0007】 Hereinafter, an embodiment of the sash 1 according to the present invention will be described with reference to the drawings. In the following explanation, the same symbols in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted where appropriate. 【0008】 [Window frame configuration] Figure 1 shows an overall schematic diagram of the sash 1, illustrating its installation in a structural opening 20 provided in the building structure 2. Figure 2 shows the mounting structure of the mullion reinforcing member 7, where (a) is an enlarged front view with a portion of the upper horizontal frame (horizontal frame) 40 cut out, and (b) is a cross-sectional view of (a) from (b) to (b). Sash 1 is a fixed window in which a panel (glass panel) 5 is fitted into a frame 4 which is composed of a mullion 3, an upper horizontal frame 40, a lower horizontal frame 41, and a vertical frame 42. The mullion 3 is positioned in the left-right center of the sash 1 with its longitudinal direction as the vertical direction. The ends of the left upper horizontal frame 40 and the lower horizontal frame 41 of the frame 4 are fixed to the left projection surface 30 of the mullion 3, and the ends of the right upper horizontal frame 40 and the lower horizontal frame 41 of the frame 4 are fixed to the right projection surface 31 of the mullion 3. The frame 4 comprises a mullion 3, an upper horizontal frame 40 and a lower horizontal frame 41, and vertical frames 42 on the left and right sides of the sash 1, with the ends of the upper horizontal frame 40 and the lower horizontal frame 41 fixed to the depth surface 421 of the vertical frame 42. Multiple anchors 6 are attached at regular intervals to the bottom of the groove 400 of the panel opening 40a of the upper horizontal frame 40, to the bottom of the groove (not shown) of the panel opening (not shown) of the lower horizontal frame 41, and to the bottom of the groove (not shown) of the panel opening (not shown) of the vertical frame 42. Furthermore, on both the left and right sides of the mullion 3, reinforcing members 7 are attached to the bottom 400 of the groove in the panel opening 40a of the upper horizontal frame 40. 【0009】 The anchor 6 and the mullion reinforcing member 7 are pre-attached to the sash 1 and welded to a welding material 21 that is welded to the inner circumferential surface 200 of the structural opening 20 in accordance with the positions of the anchor 6 and the mullion reinforcing member 7, thereby attaching the sash 1 to the structural opening 20. 【0010】 The mullion reinforcing member 7 is fixed to the bottom of the groove 400 in the panel opening 40a of the upper horizontal frame 40 by screws 7a, such that one of the left or right side portions 702 of the frame side member 70 (described later) abuts against the left and right projection surfaces 30, 31 of the mullion 3. The mullion reinforcing members 7 are located near both the left and right sides of the mullion 3. In the case of the left mullion reinforcing member 7, the right side portion 702 of the frame side member 70 abuts against the left depth surface 30 of the mullion 3, and in the case of the right mullion reinforcing member 7, the left side portion 702 of the frame side member 70 abuts against the right depth surface 31 of the mullion 3. Such mullion reinforcing members 7 are provided on the upper horizontal frames 40 fixed to the left and right sides of the mullion 3, and in the vicinity of the mullion 3, thereby increasing the joint strength of the sash 1 to the building structure 2 in the vicinity of the mullion 3, which is not directly attached to the building structure opening 20. 【0011】 In this embodiment, as shown in Figure 1, the distance between the welded materials 21 is 400 mm, the distance between the mullion 3 and the welded material 21 for the anchor 6 is 100 mm, and the distance between the mullion 3 and the welded material 21 for the mullion reinforcing member 7 is 50 mm. However, these values ​​will change depending on the size of the window frame, etc. 【0012】 In this embodiment, the welding material 21 is angle-shaped as shown in the figure and is welded to a metal profile that constitutes the frame 2. However, in the present invention, a welding material (rod-shaped material, plate-shaped material, etc.) embedded in a concrete frame may also be used (not shown). 【0013】 In this type of sash 1, the anchor 6 and mullion reinforcing member 7 are attached when the product is shipped from the factory. Then, when attaching the sash 1 to the structural opening 20, the sash 1 is placed in the structural opening 20 and its position is adjusted. The welding material 21 is then aligned with the positions of the anchor 6 and the mullion reinforcing member 7, and welded to the inner circumferential surface 200 of the structural opening 20 while facing each other and in contact in the left-right direction. After that, the anchor 6 and the mullion reinforcing member 7 are welded to the welding material 21, thereby permanently attaching the sash 1 to the structural opening 20. The mullion reinforcing member 7 has a frame-side member 70 fixed to the upper horizontal frame 40 and a connecting member 71 that is screwed to the frame-side member 70 by screws 7b. As shown in Figure 3, deformation of the mullion 3 can be prevented by allowing the expansion and contraction of the mullion 3 due to heat to be accommodated by the upward movement of the frame-side member 70 relative to the connecting member 71. The initial position of the screw 7b is set to a position where the frame-side member 70 can move freely in the vertical direction relative to the connecting member 71, taking into account the amount of extension and contraction of the mullion 3. Furthermore, although not shown in the diagram, the frame-side member 70 can also move freely in the downward direction relative to the connecting member 71. For example, if the construction period is during a cold season, the downward movement of the frame-side member 70 relative to the connecting member 71 can be allowed to accommodate the shrinkage of the mullion 3, thereby preventing deformation of the mullion 3. When the mullion 3 expands or contracts, the upper horizontal frame 40 elastically deforms to follow the expansion or contraction of the mullion 3 and moves in the vertical direction. 【0014】 The mounting position of the mullion reinforcing member 7 is not limited to a position that abuts against the depth surface 30 of the mullion 3; the mullion reinforcing member 7 may be located in the vicinity of the depth surface 30 of the mullion 3. Here, the position of the mullion reinforcing member 7 near the depth surface 30 of the mullion 3 means that it is a position where approximately the same effect can be obtained as if the mullion reinforcing member 7 were in contact with the depth surface 30 of the mullion 3. The welding position of the welding material for the mullion reinforcing member 7 is set to match the mounting position of the mullion reinforcing member 7. 【0015】 [Structure of the mullion reinforcing member] (Limitation: elongated hole) FIG. 4 is a diagram for explaining the structure of the gable reinforcement member 7, where (a) is a perspective view and (b) is an exploded perspective view. The gable reinforcement member 7 has a frame-side member 70 fixed to the upper horizontal frame 40 and a connecting member 71 screwed to the frame-side member 70 with screws 7b. 【0016】 The frame-side member 70 has a frame-side fastening portion 700 on the lower side and two fastening piece portions 701 on the left and right on the indoor side. Side surfaces 702 are erected on the left and right of the frame-side fastening portion 700, and the fastening piece portions 701 are provided on the indoor side of the side surfaces 702. The frame-side fastening portion 700 is provided with screw holes 7001 for screws 7a that are screwed into the groove bottom 400 of the panel bay 40a of the upper horizontal frame 40. Each of the fastening piece portions 701 is provided with a screw hole 7010. By passing the screw 7b through two long holes 7100 provided in the connecting member 71 and screwing it into the screw hole 7010 of the fastening piece portion 701, the connecting member 71 is fixed to the frame-side member 70. 【0017】 The connecting member 71 includes a connecting surface portion 710 provided with long holes 7100 on the indoor side and a welding surface portion 711 extending perpendicularly from the end of the connecting surface portion 710 on the side portion side (prospective side). The long holes 7100 are formed with the longitudinal direction being the vertical direction, and the connecting member 71 supported by the screw 7b passing through the long holes 7100 is allowed to move up and down by the length of the long holes 7100 with respect to the frame-side member 70. The connecting member 71 and the frame-side member 70 are allowed to move relative to each other in the vertical direction by the length of the long holes 7100. In a state where the frame-side member 70 is attached to the upper horizontal frame 40, the connecting member 71 is allowed to move in the vertical direction by the length of the long holes 7100 with respect to the frame-side member 70. The welding surface portion 711 fixes the gable reinforcement member 7 to the welding material 21 by welding in a state where the welding material 21 is abutted. 【0018】 When this type of mullion reinforcing member 7 is attached to the upper horizontal frame 40, the screw 7b faces the interior side, allowing the screw 7b to be tightened from the interior side. Furthermore, welding work can be performed from the inside. 【0019】 [Window frame installation procedure] Next, we will explain the installation procedure for window frame 1. The sash 1, which has the anchors 6 and mullion reinforcing members 7 attached in advance, is placed in the structural opening 20 of the building structure 2 and its position is adjusted. Next, the welding material 21 is welded to the inner circumferential surface 200 of the structural opening 20. At this time, the welding material 21 is aligned with the positions of the anchor 6 and the vertical reinforcing member 7, and welded to the inner circumferential surface 200 of the structural opening 20 while facing each other and in contact in the left-right direction. Finally, by welding the anchor 6 and the mullion reinforcing member 7 to the welding material 21, the sash 1 can be fixed in place in the structural opening 20. 【0020】 The mullion reinforcing members 7 are installed in such a position that, with the sash 1 properly positioned in the structural opening 20, the right side portion 702 of the frame side member 70 of the left mullion reinforcing member 7 abuts against the left projection surface 30 of the mullion 3, and the left side portion 702 of the frame side member 70 of the right mullion reinforcing member 7 abuts against the left projection surface 30 of the mullion 3. Furthermore, the connecting member 71 of the mullion reinforcing member 7 is pre-fastened to the frame side member 70 with screws 7b at the appropriate position to accommodate the thermal expansion and contraction of the mullion 3. When welding the welding material 21 for the mullion reinforcing member 7 to the inner circumferential surface 200 of the structural opening 20, the connecting member 71 of the mullion reinforcing member 7 is fastened to the frame side member 70 by tightening the screw 7b from the interior side at a predetermined position. In this state, the left welding material 21 is brought into contact with the welded surface 711 of the connecting member 71 on the left mullion reinforcing member 7 so as to face each other in the left-right direction, and the right welding material 21 is brought into contact with the welded surface 711 of the connecting member 71 on the right mullion reinforcing member 7 so as to face each other in the left-right direction, and then welded to the inner circumferential surface 200 of the structural opening 20. Then, by welding the connecting member 71 to the welding material 21, the sash 1 can be attached to the structural opening 20 of the structural frame 2 (see Figure 2). 【0021】 As described above, the sash 1 of this embodiment can absorb the thermal expansion and contraction of the mullion 3 by the sliding of the connecting member 71 relative to the frame side member 70 of the mullion reinforcing member 7, thereby preventing deformation of the mullion caused by thermal expansion and contraction. Furthermore, since the fixing work of the frame-side member 70 and the connecting member 71 of the mullion reinforcing member 7 can be performed from the indoor side, this fixing work can be easily carried out. Furthermore, since the sliding of the connecting member 71 relative to the frame-side member 70 is supported by screws 7b that pass through two elongated holes 7100 and are screwed into the frame-side member 71, the sliding of the connecting member 71 can be performed accurately. Furthermore, the mullion reinforcing members 7 are provided on the upper horizontal frames 40 fixed to the left and right sides of the mullion 3, and in the vicinity of the mullion 3, thereby increasing the joint strength of the sash 1 to the building structure 2 in the vicinity of the mullion 3 where the mullion 3 is not directly attached to the building structure opening 20. Furthermore, since the mullion reinforcing member 7 is fixed to the bottom of the groove 400 of the panel opening 40a of the upper horizontal frame 40 by screws 7a from the inner circumference side of the panel opening 40a, the installation of the mullion reinforcing member 7 can be easily performed. Furthermore, since the mullion reinforcing member 7 is fixed to the bottom of the groove 400 of the panel opening 40a of the upper horizontal frame 40 from the inner circumference side of the panel opening 40a, even if the size of the frame body 4, the depth of the upper horizontal frame 40, and even the size of the mullion 3 are changed, it is possible to secure the sliding space of the connecting member 71 relative to the frame side member 70 in the space s, and the same mullion reinforcing member 7 can be used. 【0022】 While embodiments of the present invention have been described in detail with reference to the drawings and various modifiable forms have been explained, the specific configuration is not limited to these embodiments, and design changes and the like that do not depart from the spirit of the present invention are also included. 【0023】 Furthermore, the aforementioned embodiments and various forms can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose, structure, etc. [Explanation of symbols] 【0024】 1: Sash 2:Structure 21: Welding materials 3: Mullion 40: Upper horizontal frame (frame) 40a: Panel opening 5: Panel 7: Mullion reinforcing member 70: Frame side member 71: Connecting member
