Description

[Technical Field]

[0001] The present invention relates to a frame mounting fixture for mounting an opening frame to an opening formed in a wall. [Background technology]

[0002] Patent document 1 discloses a simple opening frame structure that can be attached to openings provided in various positions on a wall that has a fire-resistant surface material (a fire-resistant board made of gypsum board, etc.) attached to a wall frame (a wall body made of wall panels, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-336451 Summary of the Invention [Problem to be solved by the invention]

[0004] The structural frame (wooden structural material) that makes up a wall is more susceptible to dimensional changes due to humidity and temperature than fire-resistant facing materials such as gypsum board. Specifically, the structural frame is more susceptible to shrinkage due to factors such as a drop in humidity than the fire-resistant facing material. Therefore, if an opening frame (a frame material that makes up an opening frame) is installed across the structural frame and the fire-resistant facing material, when the structural frame shrinks, the part of the opening frame that is fixed to the structural frame is pulled by the structural frame, and the part of the opening frame that comes into contact with the fire-resistant facing material is pushed by the fire-resistant facing material in the direction opposite to the shrinkage of the structural frame, which can cause problems.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a frame material mounting fixture for attaching an opening frame material to an opening formed in a wall, which is capable of avoiding defects caused by shrinkage of the body that makes up the wall. [Means for solving the problem]

[0006] The invention described in claim 1 is, for example, as shown in FIGS. 1 to 4 and 6 to 8, A frame material mounting tool 7 for mounting an opening frame material 61 to an opening 1a formed in a wall 1, a joint 71 joined to the skeleton (wall panel 2, adjustment material 4a) that constitutes the wall 1; A support portion 72 that supports the opening frame material 61; a connecting portion 73 that connects the joint portion 71 and the support portion 72, The opening frame material 61 is provided across the skeleton and the fire-resistant surface material 3 attached to the skeleton, The support portion 72 is The opening frame material 61 is supported so that the surface of the opening frame material 61 facing the fire-resistant face material 3 is parallel to the surface of the fire-resistant face material 3 facing the opening frame material 61, The connecting portion 73 is characterized in that it can be moved in a direction away from the joint portion 71 while maintaining the parallel state by being deformed.

[0007] According to the invention described in claim 1, when the main body shrinks and a pushing force is applied from the fire-resistant surface material 3 to a portion of the opening frame material 61 supported by the support part 72, the support part 72 moves in a direction away from the joint part 71 while maintaining the state of the opening frame material 61 relative to the fire-resistant surface material 3 (the parallel state), thereby avoiding the occurrence of defects caused by the shrinkage of the main body.

[0008] The invention described in claim 2 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The connecting portion 73 is characterized in that it is elastically deformable. That is, the support portion 72 can move in a direction away from the joint portion 71 while maintaining the parallel state by the elastic deformation of the connecting portion 73 .

[0009] According to the invention described in claim 2, even if the frame repeatedly shrinks and returns to its original shape depending on the seasons, etc., the connecting parts 73 can follow this cycle and repeatedly deform and return to their original shape. Therefore, the support parts 72 can move in the direction away from the joint parts 71 or in the opposite direction depending on the increase or decrease in the pushing force from the fire-resistant facing material 3, while maintaining the state of the opening frame material 61 relative to the fire-resistant facing material 3 (the parallel state). Therefore, the state of the opening frame material 61 relative to the fire-resistant facing material 3 can be maintained for a long period of time, regardless of the seasons, etc.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The support portion 72 is provided in plurality, The connecting portion 73 is provided between the plurality of supporting portions 72.

[0011] According to the invention described in claim 3, the frame material mounting fixture 7 supports the opening frame material 61 with a plurality of support parts 72, and furthermore, the distance between the plurality of support parts 72 is at least the length of the connecting parts 73, so that the opening frame material 61 can be supported more firmly and stably than when there is only one support part 72 or when the plurality of support parts 72 are adjacent to each other.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The support portion 72 is characterized by having a protrusion 70c that fits into a recess 61d provided in the opening frame material 61.

[0013] According to the invention described in claim 4, when the opening frame material 61 is installed in the correct position, the convex portion 70c fits into the concave portion 61d, providing a clicking sensation, making it possible to easily check the installation status of the opening frame material 61, which is difficult to check visually.

[0014] The invention described in claim 5 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 4, The convex portion 70c is characterized by being a dome-shaped protrusion.

[0015] According to the invention described in claim 5, since the convex portion 70c is a protrusion without corners, even after the convex portion 70c is fitted into the concave portion 61d, the opening frame material 61 can be pulled out from the frame material mounting fixture 7 with a force greater than a certain level, making it easy to remove the opening frame material 61 even if it becomes necessary.

[0016] The invention described in claim 6 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The joint 71 is It is joined to the body by screws B, It is characterized by having a claw portion 70b that protrudes toward the body side.

[0017] According to the invention of claim 6, before performing the screw fastening work to fasten the frame material fastening fixture 7 to the frame body with the screw B, the claw portion 70b can be pressed into the frame body to temporarily fasten the frame material fastening fixture 7 to the frame body, improving the workability of the screw fastening work. Furthermore, the claw portion 70b also contributes to preventing the frame material fastening fixture 7 from rotating when the screw B is fastened.

[0018] The invention described in claim 7 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The support portion 72 is a first plate portion (parallel plate portion 72a) provided at a position closer to the body than the opening frame material 61; a second plate portion (fitting plate portion 72c) provided at a position farther from the body than the first plate portion 72a, The opening frame material 61 is supported by being sandwiched between the first plate portion 72a and the second plate portion 72c, The tip of the first plate portion 72a is a folded portion 72a1, The tip of the second plate portion 72c is characterized by being formed as a folded portion 72c1.

[0019] According to the invention described in claim 7, the first plate portion 72a and the second plate portion 72c have folded portions, and therefore are stronger than when they do not have folded portions. Therefore, the support portion 72 can support the opening frame material 61 by sandwiching it between the high-strength plate portions, and therefore it is possible to support the opening frame material 61 firmly and stably.

[0020] The invention described in claim 8 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 7, The opening frame material 61 is bonded to the support portion 72 with an adhesive.

[0021] According to the invention described in claim 8, the opening frame material 61 is fixed to the support portion 72 by being clamped between the first plate portion (parallel plate portion 72a) and the second plate portion (fitting plate portion 72c) and by being bonded with an adhesive, so that the opening frame material 61 can be supported firmly and stably.

[0022] The invention described in claim 9 is, for example, as shown in Figs. 2 to 4 and Figs. 6 to 8, in the frame material mounting tool 7 described in claim 1, The support portion 72 is characterized in that it supports the opening frame material 61 so that the opening frame material 61 is in surface contact with the fitting frame material (such as the sash frame material 51) attached to the opening 1a.

[0023] According to the invention as set forth in claim 9, the opening frame material 61 is in surface contact with the fitting frame material 51, so that the airtightness of the opening 1a is high. Furthermore, when the state of the opening frame material 61 relative to the fire-resistant facing material 3 (the parallel state) is maintained, the surface contact state between the opening frame material 61 and the door / window frame material 51 is also maintained. Therefore, even if a pushing force is applied from the fire-resistant facing material 3 to a portion of the opening frame material 61 supported by the support portion 72, the surface contact state between the opening frame material 61 and the door / window frame material 51 is maintained, so that even if the frame shrinks depending on the season, etc., high airtightness can be maintained, which can contribute to the realization of a decarbonized society by promoting carbon neutrality and the achievement of the SDGs. [Effects of the Invention]

[0024] According to the present invention, it is possible to avoid the occurrence of problems caused by shrinkage of the frame. [Brief explanation of the drawings]

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions (front, back, left, right) in the following embodiments and illustrated examples are set solely for the convenience of explanation.

[0027] <Openings and various frame materials fixed to them> The wall 1 shown in Figures 1 and 2 is an exterior wall of a building such as a house or office. The wall 1 is provided along the perimeter of the building and faces a room or the like inside the building. The wall 1 may be an exterior wall on the first floor of the building, or an exterior wall on the second or higher floor. The wall 1 may also be an interior wall instead of an exterior wall. Furthermore, in this embodiment, the building is constructed using a panel construction method in which building components such as walls, floors, and roofs are panelized in advance at a factory and these panels (wall panels 2, floor panels, etc.) are assembled at the construction site, but this is not limited to this, and the building may also be constructed using conventional frame construction, wall construction, two-by-four construction, etc.

[0028] The wall 1 in this embodiment comprises a wall panel 2 that forms the main body of the wall 1, an exterior material (not shown) that covers the outdoor side (rear side) of the wall panel 2, and a fire-resistant facing material 3 that covers the indoor side (front side) of the wall panel 2. In other words, the fire-resistant facing material 3 is attached to the indoor side of the wall panel 2, making the wall 1 fire-resistant. In this embodiment, gypsum board is used as the fire-resistant facing material 3, but this is not limited to this and other types of fire-resistant facing materials may also be used. The wall panel 2 is made up of a rectangular frame of vertical and horizontal frame members 2a assembled together, with auxiliary beam members assembled vertically and horizontally inside the rectangular frame, and face members 2b attached to both sides of the frame, creating a hollow interior. Furthermore, the hollow interior is usually filled with insulating material such as glass wool or rock wool.

[0029] For example, a moisture-permeable waterproof sheet (not shown) is attached to the exterior side of the wall panel 2, and then furring strips (not shown) are attached on top of that, and then exterior material (not shown) is attached to the furring strips. The fire-resistant facing material 3 is an interior base material attached to the indoor side of the wall panel 2, and an interior material (not shown) such as wall paper is attached to the indoor side of the fire-resistant facing material 3.

[0030] As shown in Figure 1, an opening 1a is formed in a wall 1. This opening 1a is formed by a wall panel 2 for a small wall being provided between the upper ends of a plurality of wall panels 2 arranged at intervals on the left and right, and a wall panel 2 for a waist wall being provided between the lower ends of the plurality of wall panels 2. Additionally, adjustment members 4a made of square timbers are fixed to the side of the opening 1a in each of the multiple wall panels 2 arranged at intervals on the left and right, as a base for adjusting dimensions and attaching various components. In other words, the edge of the opening 1a is formed by the left and right adjustment members 4a facing the opening 1a, the lower end of the wall panel 2 for the small wall, and the upper end of the wall panel 2 for the waist wall.

[0031] A window sash 5 is provided in the opening 1a. This window sash 5 is a window sash for a sliding waist-high window. The window sash 5 comprises a rectangular sash frame 50 attached to the edge of the opening 1a, and a shoji screen (not shown) for closing the opening 1a. This shoji screen comprises a shoji frame formed by assembling vertical and horizontal frame members into a rectangular shape, and a rectangular pane of window glass fitted into the inner edge of the shoji frame. The sash frame 50 comprises upper and lower sash frame members 51 fixed to the lower end of the wall panel 2 for the small wall and the upper end of the wall panel 2 for the waist wall, respectively, and left and right sash frame members 51 fixed to the left and right adjustment members 4a facing the opening 1a, respectively.

[0032] The sash frame materials 51 on the top, bottom, left and right sides of the sash frame 50 have grooves that can accommodate the edges of a shoji screen (shoji frame), and the shoji screen can slide along the grooves of the top and bottom sash frame materials 51 in the sash frame 50. In the present application, of the upper sash frame material 51 fixed to the lower end of the wall panel 2 for the small wall, the lower sash frame material 51 fixed to the upper end of the wall panel 2 for the waist wall, and the left and right sash frame materials 51 fixed to the adjustment member 4a, only the upper sash frame material 51 is shown in the figure, and the others are not shown. Note that the lower sash frame material 51 may have a different shape, etc. from the upper sash frame material 51. Furthermore, the left and right sash frame materials 51 may have a different shape, etc. from the upper sash frame material 51.

[0033] In addition, the type of window sash 5 is a waist-high sliding window in this embodiment, but is not limited to this and can be changed as appropriate. That is, in addition to sliding windows, the window sashes can be changed to fixed windows, folding doors, double-hung windows, single-hung windows, double-sliding windows, single-sliding windows, vertical sliding windows, horizontal sliding windows, outward-tilting windows, inward-tilting windows, projection windows, casement windows, sash windows, pivot windows, awning windows, louvered windows, etc. Also, when classified by position or function, the window sashes can be changed to French windows, high windows, ground-level windows, bay windows, corner windows, etc. in addition to waist-high windows. Furthermore, the fixture provided on the outside (rear) side of the edge of the opening 1a in the thickness direction of the wall panel 2 is not limited to a window (window sash 5) but may be a door (door) etc. In other words, the fixture frame provided on the edge of the opening 1a is not limited to a sash frame 51 but may be a door frame etc.

[0034] In addition, an opening frame (decorative frame, fixture frame) 60 that decorates the indoor side of the edge of the opening 1a is fixed to the indoor side (front side) in the thickness direction of the wall panel 2. The opening frame 60 is a rectangular frame body comprising upper and lower opening frame members 61 fixed to the lower end of the wall panel 2 for the small wall and the upper end of the wall panel 2 for the waist wall, respectively, and left and right opening frame members 61 fixed to the left and right adjustment members 4a facing the opening 1a, respectively. As shown in Figure 3, the opening frame material 61 is a plate-like body formed to have the same cross section in the longitudinal direction, and as shown in Figure 2, it is installed across the main body (wall panel 2 and adjustment material 4a) and the fire-resistant surface material 3 attached to the indoor side of the main body.

[0035] The fire-resistant facing material 3 attached to the skeleton (wall panel 2 and adjustment material 4a) protrudes outward (toward the center of the opening 1a) from the skeleton. Therefore, the opening frame material 61 is shaped so that the portion of the opening frame material 61 facing the fire-resistant facing material 3 is thinner (has a smaller thickness) than the portion of the opening frame material 61 facing the skeleton. As a result, the apparent dimension of the opening frame 60 is the thickness dimension of the portion of the opening frame material 61 that faces the fire-resistant face material 3, so it is possible to make it appear as if a frame that is thinner than the actual opening frame 60 is installed. In other words, the opening frame 60 is configured so that the apparent dimension is a hakake (eight-sided hook, blade hook) shape.

[0036] The portion of the opening frame material 61 that faces the fire-resistant face material 3 is in contact with the fire-resistant face material 3, whereas the portion of the opening frame material 61 that faces the skeleton (wall panel 2 and adjustment material 4a) is separated from the skeleton. In other words, a gap G is provided between the portion of the opening frame material 61 that faces the skeleton and the skeleton. This gap G accommodates the fixing portions of the sash frame 50 (top, bottom, left, and right sash frame materials 51) that are fixed to the edges of the opening 1a. Furthermore, as shown in Figure 2, a frame material mounting fixture 7 is arranged in the gap G between the portion of the opening frame material 61 facing the main body and the main body, for mounting the opening frame material 61 to the edge of the opening 1a.

[0037] The opening frame material 61 may be made of wood, resin, or a wood-like molded product obtained by kneading and melting wood and resin and then extruding them. In this embodiment, a frame material made of MDF (medium density fiberboard, JISA5905) is used as the opening frame material 61. A finishing material such as a decorative sheet may be integrally attached to at least the portion of the surface of the opening frame material 61 that will be visible after installation. In the present application, of the upper opening frame member 61 fixed to the lower end of the wall panel 2 for the small wall, the lower opening frame member 61 fixed to the upper end of the wall panel 2 for the waist wall, and the left and right opening frame members 61 fixed to the adjustment member 4a, only the upper opening frame member 61 is shown in the illustration, and the others are omitted from the illustration. Note that the lower opening frame member 61 may have a different shape, etc. from the upper opening frame member 61. Also, the left and right opening frame members 61 may have a different shape, etc. from the upper opening frame member 61.

[0038] In addition, in this embodiment, the frame material fixture 7 is used when attaching the upper opening frame material 61 of the top, bottom, left, and right opening frame materials 61 to the edge of the opening 1a, and the frame material fixture 7 is not used when attaching the other opening frame materials 61 to the edge of the opening 1a, but this is not limited to this. That is, the frame material fixture 7 may be used as a mounting member for fixing the upper opening frame material 61 to the skeleton (the wall panel 2 for a small wall), or may be used as a mounting member for fixing the lower opening frame material 61 to the skeleton (the wall panel 2 for a waist wall), or may be used as a mounting member for fixing the left opening frame material 61 to the skeleton (the left adjustment member 4a), or may be used as a mounting member for fixing the right opening frame material 61 to the skeleton (the right adjustment member 4a).

[0039] <Frame material mounting fixture> 2 and 4, the frame material fixture 7 is a mounting member comprising a joint 71 that is joined to the frame (in this embodiment, the wall panel 2 for the small wall) that constitutes the wall 1, a pair of support parts 72, 72 that support the opening frame material 61 (in this embodiment, the upper opening frame material 61), and a connecting part 73 that connects the joint part 71 to the pair of support parts 72, 72. The frame material fixture 7 of this embodiment is a mounting bracket formed by bending a metal plate made of spring steel. A plurality of frame material fixtures 7 are provided for each opening frame material 61. That is, in this embodiment, a plurality of frame material fixtures 7 spaced apart in the left-right direction are fixed to the lower end of the small wall panel 2. The upper opening frame material 61 is then fixed to the lower end of the small wall panel 2 via the plurality of frame material fixtures 7.

[0040] The joint 71 is a flat portion that abuts against the side of the opening 1a of the main body (the surface facing the opening frame material 61), and has a screw hole 70a through which a screw B is passed to fix the frame material mounting fixture 7 to the main body. The joint 71 also has a claw 70b that protrudes upward (toward the frame body). The claw 70b is provided to temporarily fasten the frame material fixture 7 to the frame body. The claw 70b has a sharp tip so that it can be pushed into the frame body with a finger or the like. In other words, when the joint 71 abuts against the frame body, the claw 70b is stuck into the frame.

[0041] 2 and 3, a recessed groove 61a is formed on the rear surface (outdoor side) of the opening frame material 61 along the length direction (left-right direction) of the opening frame material 61. The rear end portion (outdoor end portion) of the opening frame material 61 that faces the building frame is divided by the recessed groove 61a into an inner portion 61b located closer to the building frame than the recessed groove 61a, and an outer portion 61c located closer to the center of the opening 1a than the recessed groove 61a. As shown in Figures 2 and 4, the support portion 72 consists of a parallel plate portion 72a parallel to the joint portion 71, a vertical plate portion 72b perpendicular to the joint portion 71, and a fitting plate portion 72c that fits into the recessed groove 61a of the opening frame material 61.

[0042] The parallel plate portion 72a is formed integrally with the vertical plate portion 72b and protrudes forward from the upper end of the vertical plate portion 72b. The corner formed by the parallel plate portion 72a and the vertical plate portion 72b is set at a right angle, and has a rounded corner shape. The tip portion (front end portion) of the parallel plate portion 72a is folded back at a right angle toward the upper side (toward the body) to form a folded portion 72a1. The fitting plate portion 72c is formed integrally with the vertical plate portion 72b and protrudes forward from the lower end of the vertical plate portion 72b. The corner formed by the fitting plate portion 72c and the vertical plate portion 72b is set to an acute angle, forming a rounded shape. The tip portion (front end portion) of the fitting plate portion 72c is folded back downward (toward the center of the opening 1a) to form a folded portion 72c1.

[0043] 2, the support portion 72 supports the opening frame material 61 by sandwiching the inner portion 61b of the opening frame material 61 from above and below between the parallel plate portion 72a and the fitting plate portion 72c. In other words, when the opening frame material 61 is supported by the support portion 72, the inner portion 61b of the opening frame material 61 is fitted into the concave portion of the support portion 72 (the concave portion formed by the parallel plate portion 72a, the vertical plate portion 72b, and the fitting plate portion 72c).

[0044] As shown in Figure 4, the connecting portion 73 consists of a parallel plate portion 73a parallel to the joint portion 71, a vertical plate portion 73b perpendicular to the joint portion 71, a fitting plate portion 73c that fits into the recessed groove 61a of the opening frame material 61, and a protruding plate portion 73d perpendicular to the joint portion 71. The parallel plate portion 73a is integral with the vertical plate portion 73b and protrudes forward from the upper end of the vertical plate portion 73b. The corner formed by the parallel plate portion 73a and the vertical plate portion 73b is set at a right angle, and has a rounded corner shape. The fitting plate portion 73c is formed integrally with the vertical plate portion 73b and protrudes forward from the lower end of the vertical plate portion 73b. The corner formed by the fitting plate portion 73c and the vertical plate portion 73b is set to an acute angle, forming a rounded shape. The tip portion (front end portion) of the fitting plate portion 73c is folded back downward (toward the center of the opening 1a). The protruding plate portion 73d is integral with the parallel plate portion 73a and protrudes upward from the front end of the parallel plate portion 73a. The corner formed by the protruding plate portion 73d and the parallel plate portion 73a is set at a right angle, and has a rounded corner shape. A joint portion 71 is integrally formed at the upper end of the protruding plate portion 73d.

[0045] The parallel plate portion 72a of the support portion 72 and the parallel plate portion 73a of the connecting portion 73 are flush with each other. The dimension of the parallel plate portion 73a of the connecting portion 73 in the front-to-rear direction is shorter than the dimension of the parallel plate portion 72a of the support portion 72, and the difference between the dimensions is set so that the front end surface of the joint portion 71 and the front end surface (folded portion 72a1) of the support portion 72 are flush with each other. The upper surface of the joint portion 71 and the upper end surface of the folded portion 72a1 are also flush with each other.

[0046] Furthermore, the vertical plate portion 72b of the support portion 72 is flush with the vertical plate portion 73b of the connecting portion 73. The vertical dimension of the vertical plate portion 72b of the support portion 72 and the vertical dimension of the vertical plate portion 73b of the connecting portion 73 are set to be the same. Furthermore, the mating plate portion 72c of the support portion 72 is flush with the mating plate portion 73c of the connecting portion 73. The front-to-rear dimension of the mating plate portion 72c of the support portion 72 and the front-to-rear dimension of the mating plate portion 73c of the connecting portion 73 are set to be the same.

[0047] The connecting portion 73 is provided between a pair of support portions 72, 72 arranged side by side, i.e., between the left support portion 72 and the right support portion 72. The fitting plate portion 73c of the connecting portion 73 is provided integrally with the fitting plate portion 72c of the left support portion 72 and the fitting plate portion 72c of the right support portion 72. In contrast, the vertical plate portion 73b of the connecting portion 73 is provided separately (with a gap) from the vertical plate portion 72b of the left support portion 72 and the vertical plate portion 72b of the right support portion 72. Similarly, the parallel plate portion 73a of the connecting portion 73 is provided separately (with a gap) from the parallel plate portion 72a of the left support portion 72 and the parallel plate portion 72a of the right support portion 72. That is, a part of the support portion 72 (the parallel plate portion 72a (including the folded portion 72a1) and the vertical plate portion 72b) is provided separately from the connecting portion 73. As a result, even if the parallel plate portion 73a or the vertical plate portion 73b of the connecting portion 73 is deformed, the shape of the supporting portion 72 is maintained.

[0048] 2 and 3, a recess (groove) 61d is formed along the length direction (left-right direction) of the opening frame material 61 on the upper surface (side surface of the body) of the portion of the opening frame material 61 that faces the body. This recess 61d is provided above the groove 61a. And, as shown in FIGS. 2 and 4, the frame material fixture 7 has a protrusion 70c that fits into the recess 61d of the opening frame material 61. The protrusions 70c are dome-shaped projections that protrude toward the opposite side from the frame body (toward the center of the opening 1a). The frame material fixture 7 has multiple (four in this embodiment) protrusions 70c spaced apart in the left-right direction. Specifically, the protrusions 70c are provided on the parallel plate portions 72a of the support portion 72 and the parallel plate portions 73a of the connecting portion 73.

[0049] 2, when the upper opening frame member 61 is attached in the correct position, the upper surface (side surface of the skeleton) of the opening frame member 61 is parallel to the lower end surface of the fire-resistant face material 3 and the lower end surface of the skeleton. In other words, when the upper opening frame member 61 is attached in the correct position, the upper surface of the portion of the opening frame member 61 that faces the fire-resistant face material 3 is in surface contact with the lower end surface of the fire-resistant face material 3, and the upper surface of the portion of the opening frame member 61 that faces the skeleton is in surface contact with the lower surface of the parallel plate portion 72a of the support portion 72 (and the parallel plate portion 73a of the connecting portion 73). Furthermore, in the portion of the opening frame material 61 facing the main body, the rear surface of the outer portion 61c located below the recessed groove 61a is located rearward (toward the outdoors) of the rear surface of the inner portion 61b located above the recessed groove 61a. That is, the dimension in the front-to-rear direction of the outer portion 61c is longer than the dimension in the front-to-rear direction of the inner portion 61b, and the difference is greater than the thickness dimension of the vertical plate portions 72b, 73b.

[0050] When the frame material mounting fixture 7 is fixed in the correct position, the protruding plate portion 73d of the connecting portion 73 abuts against the sash fin (the portion fixed to the edge of the opening 1a) of the sash frame material 51, and the vertical plate portion 72b of the support portion 72 (and the vertical plate portion 73b of the connecting portion 73) abuts against the sash frame material 51. Furthermore, the recess 61d of the opening frame material 61 and the protrusion 70c of the frame material fixture 7 that fits therein are positioned so that the rear surface of the outer portion 61c makes surface contact with the sash frame material 51. That is, when the opening frame material 61 is attached in the correct position, the rear surface of the outer portion 61c is in surface contact with the sash frame material 51. Therefore, when the opening frame material 61 is attached in the correct position, the rear surface of the outer portion 61c is flush with the rear surfaces of the vertical plate portions 72b of the support portions 72 (and the vertical plate portions 73b of the connecting portions 73). Furthermore, when the opening frame material 61 is attached in the correct position, the opening frame material 61 is sandwiched from the front and back between the sash frame material 51 and the fire-resistant surface material 3.

[0051] The building's framework (wooden structural materials such as wall panels 2 and adjustment materials 4a) is more susceptible to dimensional changes due to the effects of humidity and temperature than fire-resistant facing materials 3 such as gypsum board. Specifically, the framework is more susceptible to shrinkage due to factors such as a drop in humidity than the fire-resistant facing materials 3. Therefore, even if the framework shrinks due to factors such as a drop in humidity, the fire-resistant facing materials 3 attached to the framework do not shrink (their shrinkage rate is smaller than that of the framework), and therefore, when the framework shrinks, the protruding dimensions of the fire-resistant facing materials 3 relative to the framework change (the protruding dimensions become longer than the designed dimensions).

[0052] Because the frame is fixed to the skeleton, the portion of the frame that is fixed to the skeleton is pulled by the shrinkage of the skeleton. On the other hand, even if the skeleton shrinks, the fire-resistant facing material 3 does not shrink (its shrinkage rate is smaller than that of the skeleton). Therefore, the portion of the frame that contacts the fire-resistant facing material 3 is pushed by the fire-resistant facing material 3 in the direction opposite to the shrinkage direction of the skeleton. Therefore, if the skeleton shrinks and the protrusion dimension of the fire-resistant facing material 3 from the skeleton becomes longer than the design dimension, a pushing force is applied from the fire-resistant facing material 3 to a portion of the frame (the portion of the frame that faces the fire-resistant facing material 3). For example, as shown in Figure 5, the frame may become tilted relative to the fire-resistant facing material 3 or may become warped, causing the surface of the frame that faces the fire-resistant facing material 3 to become non-parallel to (not in surface contact with) the surface of the fire-resistant facing material 3 that faces the frame.

[0053] The dashed-dotted line in Fig. 5 indicates the fire-resistant facing material 3 when the skeleton (wall panel 2) has shrunk, and the two-dot chain line in Fig. 5 indicates the opening frame material (upper opening frame material) when the skeleton (wall panel 2) has shrunk. When the skeleton shrinks, the protruding dimension of the fire-resistant facing material 3 from the skeleton becomes longer than the designed dimension, as shown by the dashed-dotted line in Fig. 5, and the opening frame material tilts or bends, as shown by the two-dot chain line in Fig. 5. When the opening frame material tilts or bends, defects such as deformation of the opening frame material or the formation of a gap between the fire-resistant facing material 3 and the opening frame material occur. Furthermore, if the main body shrinks and the protruding dimension of the fire-resistant surface material 3 relative to the main body becomes longer than the design dimension (a pushing force is applied from the fire-resistant surface material 3 to a part of the opening frame material), problems such as the opening frame material cracking or the end of the fire-resistant surface material 3 being crushed before the opening frame material tilts or bends may occur.

[0054] In particular, the opening frame material attached to the wall panel 2 (or lintel, etc.) for the small wall, that is, the upper opening frame material, is prone to the above-mentioned problems. Therefore, in this embodiment, the upper opening frame material 61 is fixed to the wall panel 2 for the small wall (or a lintel or the like) via a frame material fixture 7.

[0055] The frame material fixture 7 of this embodiment is made of an elastically deformable material (such as spring steel). In addition, in the frame material fixture 7, the parallel plate portion 72a and the vertical plate portion 72b of the support portion 72 are provided with a gap between them and the parallel plate portion 73a and the vertical plate portion 73b of the connecting portion 73. Therefore, when a pushing force is applied to the support portion 72 from above, the connecting portion 73 deforms, and the support portion 72 moves in a direction away from the joint portion 71 (a direction away from the frame). At this time, the connecting portion 73 deforms but the support portion 72 does not deform, and the shape of the support portion 72 is maintained.

[0056] When the main body shrinks and a pushing force is applied from the fire-resistant facing material 3 to a part of the opening frame material 61, a pushing force (a force in a direction away from the joint part 71) is also applied to the support part 72 from the fire-resistant facing material 3 via the opening frame material 61. Therefore, as shown in Figure 6(b) for example, when the main body shrinks, in the frame material fixture 7, only the connecting part 73 deforms, and the support part 72 moves in a direction away from the joint part 71 while maintaining the state of the opening frame material 61 relative to the fire-resistant facing material 3 (the surface of the opening frame material 61 facing the fire-resistant facing material 3 being parallel to (in surface contact with) the surface of the fire-resistant facing material 3 facing the opening frame material 61).

[0057] 7(b), for example, the angle of the corner formed by the parallel plate portion 73a and the vertical plate portion 73b and the angle of the corner formed by the parallel plate portion 73a and the protruding plate portion 73d of the connecting portion 73 deforms so that it becomes an obtuse angle from a right angle. In other words, when the body shrinks, the connecting portion 73 deforms so that the parallel plate portion 73a becomes inclined from a parallel state with respect to the joint portion 71, and the vertical plate portion 73b becomes inclined from a perpendicular state with respect to the joint portion 71.

[0058] Even if the parallel plate portion 73a and the vertical plate portion 73b of the connecting portion 73 are deformed, the support portion 72 is not deformed, and the state of the parallel plate portion 72a (parallel to the joint portion 71) and the state of the vertical plate portion 72b (perpendicular to the joint portion 71) are maintained. Therefore, even if the main body shrinks and the connecting portion 73 is deformed, the opening frame material 61 supported by the support portion 72 will not tilt or bend, and will move in a direction away from the main body while the surface of the opening frame material 61 facing the fire-resistant face material 3 remains parallel to the surface of the fire-resistant face material 3 facing the opening frame material 61 (in face-to-face contact). Therefore, by using the frame material mounting fixture 7 to attach the opening frame material 61 to the edge of the opening 1a, it is possible to avoid the occurrence of the above-mentioned defects caused by shrinkage of the main body (deformation of the opening frame material 61, the occurrence of gaps between the fire-resistant surface material 3 and the opening frame material 61, cracking of the opening frame material 61, crushing of the edge of the fire-resistant surface material 3, etc.).

[0059] Furthermore, when the degree of shrinkage of the building frame decreases due to an increase in humidity, etc., the protruding dimension of the fire-resistant facing material 3 from the building frame approaches the design dimension, and the pushing force from the fire-resistant facing material 3 decreases. Because the deformation of the connecting portion 73 is elastic, when the protruding dimension of the fire-resistant facing material 3 from the building frame returns to the design dimension, the parallel plate portion 73a of the connecting portion 73 returns to its original state (parallel to the joint portion 71), and the vertical plate portion 73b of the connecting portion 73 returns to its original state (perpendicular to the joint portion 71), as shown in Figures 6(a) and 7(a), for example. In other words, in the frame material mounting fixture 7 of this embodiment, the support portion 72 can move (up and down) away from the joint portion 71 or in the opposite direction, while maintaining the state of the opening frame material 61 relative to the fire-resistant surface material 3 (parallel state, surface contact state), in accordance with changes in the protruding dimensions of the fire-resistant surface material 3 relative to the main body (according to increases or decreases in the pushing force from the fire-resistant surface material 3).

[0060] <Frame material installation method> Next, with reference to FIGS. 2 and 8, an example of a procedure for attaching the opening frame material 61 to the edge of the opening 1a using the frame material attachment tool 7 will be shown. First, the sash frame material 51 is fixed to the building frame (wall panel 2, adjustment material 4a) with screws or the like.

[0061] 8(a), the claw portion 70b of the frame material fixture 7 is pressed into the frame body with a finger or the like to temporarily fix the frame material fixture 7 to the frame body. At this time, the frame material fixture 7 is temporarily fixed in a state where the connecting portion 73 (protruding plate portion 73d) abuts against the sash fin (the portion fixed to the edge of the opening 1a) of the sash frame material 51. Next, as shown in FIG. 8(a), the frame material fixture 7 is fixed to the frame body with screws B. Next, adhesive is applied to the portion of the support portion 72 of the frame material fixture 7 that will come into contact with the opening frame material 61. At this time, adhesive is not applied to the connecting portion 73.

[0062] Next, as shown in Figure 8(b), the inner portion 61b of the opening frame material 61 is fitted into the recessed portion of the frame material fixture 7 (the recessed portion formed by the parallel plate portions 72a, 73a, the vertical plate portions 72b, 73b, and the mating plate portions 72c, 73c), thereby attaching the opening frame material 61 to the frame material fixture 7. At this time, the inner portion 61b of the opening frame material 61 is inserted into the recessed portion of the frame material fixture 7 until the protruding portion 70c of the frame material fixture 7 fits into the recessed portion 61d of the opening frame material 61 (until a click is felt). As a result, the opening frame material 61 is fixed to the edge of the opening 1a, with the outer portion 61c in surface contact with the sash frame material 51.

[0063] Since the convex portion 70c is a dome-shaped protrusion without corners, even after the opening frame material 61 is attached to the frame material mounting fixture 7 (after the convex portion 70c fits into the recessed portion 61d), the opening frame material 61 can be pulled out of the frame material mounting fixture 7 with a force greater than a certain level as long as the adhesive has not yet hardened. Thereafter, the fire-resistant facing material 3 is attached to the indoor side of the building frame, as shown in Fig. 2. At this time, the surface of the fire-resistant facing material 3 facing the opening frame material 61 and the surface of the opening frame material 61 facing the fire-resistant facing material 3 are in surface contact with each other.

[0064] <Effects> According to this embodiment, the following excellent effects are achieved. The frame material mounting fixture 7 of this embodiment is a frame material mounting fixture for mounting an opening frame material 61 to an opening 1a formed in a wall 1, and is provided with a joint 71 that is joined to the main body (wooden structural materials such as wall panels 2, adjustment materials 4a, and lintels) that constitutes the wall 1, a support part 72 that supports the opening frame material 61, and a connecting part 73 that connects the joint 71 and the support part 72, and the opening frame material 61 is arranged to straddle the main body and the fire-resistant surface material 3 attached to the main body. The support portion 72 supports the opening frame material 61 so that the surface of the opening frame material 61 facing the fire-resistant surface material 3 is parallel to the surface of the fire-resistant surface material 3 facing the opening frame material 61 (the surface of the opening frame material 61 facing the fire-resistant surface material 3 is in face-to-face contact with the surface of the fire-resistant surface material 3 facing the opening frame material 61), and by deforming the connecting portion 73, it can move in a direction away from the joint portion 71 while maintaining the parallel state (the face-to-face contact state).

[0065] Therefore, when the main body shrinks and a pushing force is applied from the fire-resistant face material 3 to a part of the opening frame material 61 supported by the support part 72, the support part 72 moves in a direction away from the joint 71 while maintaining the state of the opening frame material 61 relative to the fire-resistant face material 3 (the parallel state, the face-to-face contact state), thereby avoiding the occurrence of defects caused by the shrinkage of the main body (deformation of the opening frame material 61, the occurrence of a gap between the fire-resistant face material 3 and the opening frame material 61, cracking of the opening frame material 61, crushing of the end of the fire-resistant face material 3, etc.).

[0066] Furthermore, in the frame material fixture 7 of this embodiment, the connecting portion 73 is elastically deformable. That is, even if the building frame repeatedly shrinks and returns to its original state (returning to the state before shrinkage, returning to the state at the time of construction) depending on the season, etc., the connecting parts 73 can follow this repetition and repeatedly deform and return to their original state (returning to the state before deformation, returning to the state at the time of construction). Therefore, the support parts 72 can move up and down while maintaining the state of the opening frame member 61 relative to the fire-resistant facing material 3 (the parallel state, the face-to-face contact state) and following changes in the protruding dimension of the fire-resistant facing material 3 relative to the building frame (according to increases and decreases in the pushing force from the fire-resistant facing material 3), so the state of the opening frame member 61 relative to the fire-resistant facing material 3 can be maintained for a long period of time regardless of the season, etc. In this embodiment, the entire frame material fixture 7 is made of an elastically deformable material, but this is not limiting, and it is sufficient that at least the connecting portion 73 is elastically deformable.

[0067] Moreover, the frame material fixture 7 of this embodiment is provided with a plurality of (two) support portions 72, and connecting portions 73 are provided between the plurality of support portions 72. Therefore, the frame material mounting fixture 7 supports the opening frame material 61 using multiple support parts 72, and further, the distance between the multiple support parts 72 is at least the length of the connecting parts 73, so that the opening frame material 61 can be supported more firmly and stably than when there is only one support part 72 or when multiple support parts 72 are adjacent to each other. The connecting portion 73 does not have to be provided between multiple support portions 72. Furthermore, the number of support portions 72 provided on the frame material fixture 7 is not limited to two, but may be three or more. Furthermore, the number of support portions 72 is not limited to multiple, but may be one.

[0068] In the frame material fixture 7 of this embodiment, the support portion 72 is provided with a protrusion 70c that fits into a recess 61d provided in the opening frame material 61. Therefore, when the opening frame member 61 is attached in the correct position, the convex portion 70c fits into the concave portion 61d, providing a clicking sensation. This makes it easy to check the attachment status of the opening frame member 61 (whether the opening frame member 61 is attached in the correct position), which is difficult to check visually, thereby improving the workability of the frame attachment work of attaching the opening frame member 61 to the opening 1a. Furthermore, the protrusions 70c have the function of eliminating gaps with the sash frame material 51 by adjusting the position of the protrusions 70c relative to the recesses 61d. In other words, the protrusions 70c have the function of moving the opening frame material 61 toward the sash frame material 51, so that simply by fitting the protrusions 70c into the recesses 61d, the opening frame material 61 can be attached in the correct position (a position where the outer portion 61c of the opening frame material 61 is in surface contact with the sash frame material 51), improving the workability of the frame material attachment work. Furthermore, the position of the recess 61d can be adjusted for each production lot, allowing for improvements as needed. That is, the position of the recess 61d can be finely adjusted for each production lot using a cutting tool set on a woodworking machine, etc., so that, for example, the degree to which the recess 61d is brought closer to the sash frame material 51 can be improved as needed to meet customer needs.

[0069] Furthermore, in the frame material fixture 7 of this embodiment, the convex portion 70c provided on the support portion 72 is a dome-shaped protrusion without corners. Therefore, since the convex portion 70c is a protrusion without corners, even after the convex portion 70c fits into the concave portion 61d, the opening frame material 61 can be pulled out of the frame material mounting fixture 7 with a force greater than a certain level as long as the adhesive has not hardened. This makes it easy to remove the opening frame material 61 even if it is necessary to do so due to a construction error or other reason.

[0070] Furthermore, in the frame material fixture 7 of this embodiment, the joint portion 71 is joined to the frame body by a screw B and is provided with a claw portion 70b that protrudes toward the frame body side. Therefore, before performing the screwing work of fixing the frame material fixture 7 to the skeleton with the screws B, the frame material fixture 7 can be temporarily fixed to the skeleton by pressing the claw portions 70b into the skeleton with a finger or the like, thereby improving the workability of the screwing work. As in this embodiment, the screwing work of fixing the frame material fixture 7 to the surface to which the upper opening frame material 61 is fixed (the lower end surface of the wall panel 2 for the small wall) is difficult to perform because it requires working while facing upward, so temporary fixing with the claw portions 70b is particularly effective. Furthermore, the claw portion 70b also contributes to preventing rotation of the frame material fixture 7 when tightening the screw B. In other words, since the screw tightening work is performed with the claw portion 70b inserted into the frame body, the claw portion 70b can prevent the frame material fixture 7 from rotating together with the screw B when tightening the screw, improving the workability of the screw tightening work.

[0071] In addition, in the frame material mounting fixture 7 of this embodiment, the support portion 72 comprises a first plate portion (parallel plate portion 72a) that is provided at a position closer to the main body than the opening frame material 61, and a second plate portion (fitting plate portion 72c) that is provided at a position farther from the main body than the first plate portion 72a, and supports the opening frame material 61 by sandwiching it between the first plate portion 72a and the second plate portion 72c, with the tip of the first plate portion 72a being a folded portion 72a1 and the tip of the second plate portion 72c being a folded portion 72c1. That is, since the first plate portion 72a and the second plate portion 72c have folded portions, they are stronger than those without folded portions. Therefore, the support portion 72 can sandwich and support the opening frame material 61 with the high-strength plate portions, so it is possible to support the opening frame material 61 firmly and stably.

[0072] In the frame material fixture 7 of this embodiment, the opening frame material 61 is adhered to the support portion 72 with an adhesive. Therefore, the opening frame material 61 is fixed to the support portion 72 by being clamped between the first plate portion (parallel plate portion 72a) and the second plate portion (fitting plate portion 72c) and by being bonded with an adhesive, so that the opening frame material 61 can be supported firmly and stably.

[0073] In addition, in this embodiment, the support portion 72 supports the opening frame material 61 so that the opening frame material 61 is in surface contact with the fitting frame material (such as the sash frame material 51) attached to the opening 1a. Therefore, the opening frame material 61 is in surface contact with the fitting frame material 51, and therefore the airtightness of the opening 1a is high. Furthermore, when the state of the opening frame material 61 relative to the fire-resistant facing material 3 (the parallel state, the face-to-face contact state) is maintained, the face-to-face contact state between the opening frame material 61 and the door / window frame material 51 is also maintained. Therefore, even if a pushing force is applied from the fire-resistant facing material 3 to a portion of the opening frame material 61 supported by the support portion 72, the face-to-face contact state between the opening frame material 61 and the door / window frame material 51 is maintained, so that high airtightness can be maintained even if the frame shrinks depending on the season, etc. (for example, it shrinks by about 1 to 3 mm in about six months). In recent years, there has been a demand for a decarbonized society through the promotion of carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the Sustainable Development Goals (SDGs). In response, the construction industry is also working to build buildings using wood, which reduces carbon dioxide emissions. By attaching the opening frame 61 to the opening using the frame fixture 7, airtightness is improved, which reduces power consumption within the building. Therefore, the frame fixture 7 can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs. [Explanation of symbols]
