The reinforcing member 5 constitutes one of the attachment means for attaching the upper frame 1 to the structure on the frame side. As shown in FIG. 4, the left end of the first facing surface 10 of the upper frame 1 and the end surface 53 of the reinforcing member 5 are located on the same vertical plane.

The frame-side structure according to the present embodiment includes an opening frame material (sometimes referred to as a reinforcing frame material) 3 to which the door frame is fixed, and a base frame material to which the opening frame material 3 is fixed. It is composed of and. The base frame material horizontally connects left and right studs 4 extending in the vertical direction, runners 4' that horizontally connects predetermined parts on the upper side of the left and right studs 4 in the height direction, and horizontally connects the lower end parts of the left and right studs 4. and a runner (not shown). Typically, the opening frame member 3, stud 4, and runner are made of metal (for example, steel).

The stud 4 is a long member that has a U-shape in cross section and extends in the height direction from a first facing side 40, a second facing side 41, and an expected side 42, with the expected side 42 facing the opening side. It is provided in a vertical position. The runner 4' is an elongated member that has substantially the same cross-sectional shape as the stud 4 and extends in the horizontal direction, and is provided with its prospective side positioned on the opening side (lower side).

The opening frame member 3 is an elongated member having a U-shape in cross section including a first found side 30, a second found side 31, and an expected side 32. The opening frame material 3 is fixed to the stud 4 in a vertical position with the expected side 32 located on the opening side, and fixed to the runner 4' in a horizontal position with the expected side 32 located on the opening side (lower side). be done. More specifically, the tips of the first facing side 30 and the second facing side 31 of the opening frame material 3 are bent inward to form bent pieces 300 and 310, and the opening frame material 3 is The bent pieces 300 and 310 are fixed in contact with the expected side 42 of the stud 4 and the expected side of the runner 4'. Welding is exemplified as a means for fixing the opening frame member 3. At the stage of attaching the opening frame material 3, there are no combustible materials on site that would cause problems with hot work, so no problems will occur due to the use of welding. Note that the opening frame member 3 may be fixed to the stud 4 and runner 4' using screws.

As described above, in this embodiment, the structure on the building frame side is composed of the opening frame material 3, the studs 4, and the runners 4', and the door frame (three-sided structure consisting of the upper frame 1 and the left and right vertical frames 2). The frame) is fixed after being positioned by adjusting the position relative to the structure on the frame side (opening frame member 3). This position adjustment includes position adjustment of the door frame relative to the opening frame member 3 in the facing direction. The position adjustment of the door frame in the facing direction is mainly the position adjustment in the X direction and the Z direction in FIGS. 2, 9, and 10.

Adjustment of the position of the door frame in the facing direction will be described with reference to FIGS. 9 and 10. 9 and 10 are diagrams exclusively for explaining the position adjustment of the door frame in the finding direction, and the door frame (upper frame 1', left and right vertical frames 2') and opening shown in FIGS. It should be noted that the fixing structure with the frame material 3 is different from the fixing structure of the door frame according to this embodiment. The dimensions of the vertical rectangular space surrounded by the opening frame material 3, which is the structure on the frame side, are slightly larger than the external dimensions of the door frame (upper frame 1', left and right vertical frames 2'), and The prospective surface on the back side (the first outer prospective side 23, the second outer prospective side 24) and the prospective side 32 of the opening frame member 3 are spaced apart from each other and face each other through a gap. By adjusting the dimensions of this gap (dimensions in the X direction, Z direction), the position of the door frame relative to the opening frame member 3 in the facing direction is adjusted. Note that the approximate position of the door frame relative to the opening frame member 3 in the expected direction (Y direction) may be adjusted.

As a specific adjustment method, a method using a so-called wedge K can be exemplified. Insert a wedge K with a right-angled triangular cross-sectional view into the gap from the first and second sides in the perspective direction, and combine the two wedges K so that their sloped surfaces overlap (wedge set), depending on the degree of overlap of the sloped surfaces. The thickness of the wedge set is variable, and the gap between the door frame and the opening frame material is determined by the thickness of the wedge set. The illustrated wedge K is an example, and the shape of the wedge is not limited to a right triangle in cross section, and the number of wedges inserted into the gap is not limited either, and may be one or three or more.

In the example shown in FIG. 9, wedge sets are provided at both the left and right ends of the upper frame 1', at the upper and lower parts of the left and right vertical frames 2', and at the lower ends of the left and right vertical frames 2', so that the expected direction of the door frame is While adjusting the position of the door frame, temporarily fix the position of the door frame (position in the X direction and position in the Z direction). After the temporarily fixed door frame is fixed to the opening frame material 3 using a plurality of wedge sets, the wedges K are removed.

In this embodiment as well, gaps (wedge insertion portions K') into which wedges are inserted are formed at both left and right end portions of the upper frame 1 and at upper and lower portions of the left and right vertical frames 2 (Fig. 1 , see FIG. 3), the position of the door frame in the facing direction can be adjusted using a wedge. In this embodiment, when inserting the wedge, the position of the door frame in the expected direction (Y direction) is also adjusted. Here, adjusting the position of the door frame in the expected direction includes adjusting the inclination of the door frame in the front-rear direction.

In FIG. 6(D), the second plate-like part 61 of the end-connecting member 6A and the second plate-like part 61 of the end-connecting member 6B are arranged so as to overlap from above the upper surface 53 of the reinforcing member 5 of the vertical frame 2. They are in contact with each other, forming a region that overlaps vertically in plan view, and the insertion hole 610 formed in the second plate-shaped portion 61 is located in the overlap region. Similarly, the second plate portion 61 of the end connecting member 6A and the second plate portion 61 of the end connecting member 6B are in contact with the end surface 53 of the reinforcing member 5 of the upper frame 1 so as to overlap from the outside. , an overlapping region is formed, and the insertion hole 610 formed in the second plate-shaped portion 61 is located in the overlapping region. The position of the door frame can be adjusted in the sight direction (X direction) and the sight direction (Y direction) with respect to the opening frame member 3 within the range where this overlap region is formed. Using wedges as appropriate, adjust the position of the door frame in the sight direction and the sight direction. As described above, the second plate-shaped portion 61 and the upper surface 53 of the reinforcing member 5 may be close to each other (separated from each other) in the overlap region.

The position of the door frame relative to the opening frame material 3 is adjusted in the sight direction (X direction) and the sight direction (Y direction), and the door frame is positioned above the end connecting members 6A and 6B fixed to the opening frame material 3. Once the position of the part is determined, the second plate-like part 61 of the end connecting member 6A and the second side part of the upper end surface 53 of the reinforcing member 5 are fixed with screws S3, and the second plate-like part of the end connecting member 6B is fixed. The portion 61 and the first side portion of the upper end surface 53 of the reinforcing member 5 are fixed with screws S4 to temporarily fix the upper portion of the door frame (see FIG. 7).

Next, the intermediate portion of the opening frame member 3 and the intermediate portion of the reinforcing member 5 are fixed via the elongated connecting members 7A and 7B. Specifically, one end side portion in the width direction of the connecting member 7A is brought into contact with the intermediate portion of the second facing side 31 of the opening frame member 3 and fixed with the screw S5, and the other end side portion in the width direction of the connecting member 7A The gap between the end portion and the middle portion of the second facing piece 51 of the reinforcing member 5 is adjusted by the spacer 8, and the gap between the other end side portion of the connecting member 7A in the width direction and the second facing piece 51 of the reinforcing member 5 is adjusted. The intermediate portion is fixed using a screw S6 with a spacer 8 in between. One end of the connecting member 7B in the width direction is brought into contact with the middle part of the first facing side 30 of the opening frame member 3 and fixed with a screw S7, and reinforced with the other end of the connecting member 7B in the width direction. The gap between the intermediate part of the first facing piece 50 of the member 5 is adjusted with the spacer 8, and the other end side part in the width direction of the connecting member 7B and the intermediate part of the first facing piece 50 of the reinforcing member 5 are It is fixed using screws S8 with the spacer 8 sandwiched therebetween. After the door frame is fixed to the opening frame material 3, the finishing wall panel W is attached, and the structure for fixing the door frame to the opening frame material 3 is not exposed to the outside (see Fig. 8). ). Note that the timing of providing the spacer 8 is not limited, and for example, after the connecting members 7A and 7B are fixed to the second facing side 31 and the first facing side 30 of the opening frame member 3 with screws S5 and S7, It may also be inserted between the opening frame member 3 and the reinforcing member 5 (for example, when the connecting members 7A and 7B are short pieces). Alternatively, the spacer 8 may be provided in advance on the second facing piece 51, the first facing piece 50 of the reinforcing member 5, or the connecting members 7A, 7B.

Although the door frame fixing process has been explained with a focus on the fixing process of the vertical frame 2 to the opening frame material 3, the fixing structure of the upper frame 1 to the opening frame material 3 also has the same structure, and is fixed in the same process. can be done.

Specifically, in order to fix the upper frame 1, the first plate-like portions 60 of the end connecting member 6A are attached to both ends in the length direction of the first found side 30 of the opening frame member 3 extending in the opening width direction. A step of fixing the proximal part of the end connecting member 6B with the screw S1, fixing the proximal part of the end connecting member 6B to both lengthwise ends of the second facing side 31 of the opening frame member 3 extending in the opening width direction. A step of fixing the reinforcing member 5 of the upper frame 1 with S2, a step of fixing the end surfaces 53 at both lengthwise ends of the reinforcing member 5 of the upper frame 1 with the second plate-shaped portion 61 of the end connecting member 6A with screws S3, and a step of fixing the reinforcing member 5 of the upper frame 1 with A step of fixing the end surfaces 53 at both lengthwise ends and the second plate-like portion 61 of the end connecting member 6B with screws S4, and fixing the intermediate portion of the second facing side 31 of the opening frame member 3 and the second plate-like portion of the reinforcing member 5. A step of fixing the intermediate portion of the indexing piece 51 with screws S5 and S6 via the connecting member 7A, and fixing the intermediate portion of the first indexing side 30 of the opening frame member 3 and the first indexing piece 50 of the reinforcing member 5. Although it may include a step of fixing the intermediate portion with screws S7 and S8 via the connecting member 7B, these steps can be performed at any timing that does not interfere with the position adjustment of the door frame relative to the opening frame member 3. Please note. For example, the end connecting members 6A, 6B may be attached to the upper frame 1 first, and then the end connecting members 6A, 6B may be attached to the vertical frame 2. Further, the end connecting members 6A, 6B may be attached only to the vertical frame 2, or the end connecting members 6A, 6B may be attached only to the upper frame 1.
