[Modes for carrying out the invention]

[0007] The method for manufacturing an opening building material according to an embodiment of the present invention will be described below 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] In the manufacturing method of this embodiment, the opening building material 1 as a sliding window shown in Figure 1 will be described, but the opening building material 1 is not limited to a sliding window; any structure having a frame is acceptable.

[0009] (Basic structure of building materials for openings) First, the basic structure of the opening material 1 attached to the structural opening a1 of the structural frame a will be explained. As shown in Figure 1, the opening material 1 comprises a frame 2 and two sliding doors 3 supported within the frame 2, and is attached by mounting fixtures 4a, 4b, and 4c interposed at predetermined positions in the space s between the outer circumference of the frame 2 and the inner circumference of the structural opening a1 of the structural frame a. The frame body 2 is formed by the left and right vertical frames 2a, the upper horizontal frame 2b, and the lower horizontal frame 2c so as to surround the four sides, and the shoji 3 is supported slidably on the inner peripheral side of the frame body 2. The fixture 4a is for the vertical frame 2a and the upper horizontal frame 2b, the fixture 4b is for the lower horizontal frame 2c, and the fixture 4c is for the lower horizontal frame 2c and has a height adjustment function. As shown in FIGS. 1 to 3, the space s is filled with the filling material 5, and a tape b is attached to the portion exposed from the space s to hide the exposed filling material. The filling material 5 is used to ensure heat insulation, sound absorption, sound insulation, etc. As the material, it can be easily compressed and expands from the compression to return to the original shape. Examples of such materials include foamed materials such as non-woven fabrics and sponges made of flexible fibers.

[0010] (Manufacturing method of opening building materials) Next, the manufacturing method of the aforementioned opening building material 1 will be described with reference to FIGS. 4 to 12. [Step 1: Refer to FIG. 4] Step 1 is a step of preparing a loaded member 7 in which the compressible and expandable filling material 5 made of the aforementioned material is hermetically packaged in a compressed state by a packaging material 6. The loaded member 7 is obtained by loading and enclosing the filling material 5 in a packaging material 6 having a shape defined in advance using polyethylene or the like, applying decompression to compress and miniaturize it, and transporting it to the construction site together with the opening building material 1. Various loaded members 7 having shapes defined according to the loading positions are prepared. Examples of the shape of the loaded member 7 include the following sizes. For the upper horizontal frame side and the vertical frame side at the loading position (a): width of about 70 mm × thickness (20 to 30 mm during decompression) × length of about 400 mm (hereinafter referred to as "extra-large size"). For the lower horizontal frame side at the loading position (i): width of about 70 mm × thickness (20 to 30 mm during decompression) × length of about 200 mm (hereinafter referred to as "large size"). For the end corner of the loading position (U): width approximately 70 mm × thickness (20 - 30 mm during decompression) × length approximately 100 mm (hereinafter referred to as "medium size"). For the fixture side of the loading position (E): width approximately 30 mm × thickness (10 - 20 mm during decompression) × length approximately 100 mm (hereinafter referred to as "small size"). As another example of the loading member 7 for the end corner, as shown in FIG. 4(c), the corner portion of the loading material 5 may be cut out at a right angle to correspond to the shape of the end corner of the loading position. Also, as another example of the loading member 7 for the end corner, it may be a loading member bent at 90 degrees (not shown). Also, as the loading member 7 for the end corner, examples include those in which the corner portion of the loading material 5 is cut out at 45 degrees (not shown) and those in which the loading material 5 is made triangular (not shown).

[0011] [Step 2: Refer to FIGS. 5, 6(a) - (c)] Step 2 is a step of fixing the opening building material 1 to the housing opening a1 by the fixtures 4a - 4c. In the present embodiment, the fixing of the opening building material 1 by the fixtures 4a - 4c in Step 2 is a main fixing, and after this main fixing, the loading operation of the loading member 7 in Step 3 described later is performed. The loading operation of the loading member 7 in Step 3 may be performed before the main fixing of the opening building material 1 by the fixtures 4a - 4c.

[0012] Here, the fixture 4a is made of metal and includes a housing - side fixing member 40a provided on the inner - peripheral side of the housing opening a1 and a frame - side fixing member 41a. The housing - side fixing member 40a is convex and is fixed to the housing opening a1 with the convex side facing downward by a concrete anchor 42a. The frame - side fixing member 41a is concave and is attached to the upper horizontal frame 2b by an uneven engagement with the opening side facing upward. The frame-side fixing member 41a is engaged with the frame-side fixing member 40a in a way that allows it to slide freely in the vertical direction, and is capable of absorbing the vertical movement of the opening building material 1 caused by the height adjustment of the mounting fixture 4c, which has a height adjustment function. The same mounting bracket 4a is also used on the vertical frame side, but in this case, the convex direction of the structural frame side fixing member 40a is in the left-right direction, and the opening side of the frame side fixing member 41a is in the left-right direction (not shown). In other words, it is possible to adjust the left-right direction of the opening building material 1 when it is placed in the structural opening a1.

[0013] The mounting fixture 4b is made of metal and comprises a structural-side fixing member 40b provided on the inner circumference side of the structural opening a1 and a frame-side fixing member 41b. The structural frame-side fixing member 40b is convex in shape and is fixed to the convex structural frame opening a1 with concrete anchors 42b, with the convex side facing upward. The frame-side fixing member 41b has a concave shape and is attached to the lower horizontal frame 2c by a concave-convex engagement, with the opening side facing downwards. The frame-side fixing member 41b is engaged with the structural-side fixing member 40b in a way that allows it to slide freely in the vertical direction, and is designed to accommodate the vertical movement of the opening building material 1 that occurs when the height of the mounting fixture 4c, which has a height adjustment function, is adjusted.

[0014] The mounting bracket 4c is made of metal and comprises a height adjuster 40c and a frame-side fixing member 41c connected to the height adjuster 40c. The height adjustment device 40c consists of a bolt and a nut. A bolt 401 is screwed from below into a nut 400 that is non-rotatably mounted on the frame-side fixing member 41c, so that the head of the bolt 401 rests on the structural opening a1. Since this height adjustment device 40c adjusts the height by rotating the bolt 401, it is easy to use, yet allows for highly accurate positioning of the height of the opening building material 1.

[0015] (Step 3: See Figures 1, 8-12) Step 3 is the step of positioning the loading member 7 at a predetermined location in the space s between the outer circumference of the frame 2 and the inner circumference of the structural opening a1 of the structural body a. In this embodiment, the loading member 7 is loaded into the structural opening a1, the frame 2, and the mounting fixtures 4a to 4c according to the shape of each loading position (a) to (d). The loading and holding methods for the loading member 7 include loading and holding it at each loading position (a) to (d) using release paper (double-sided tape) or the like (not shown) on the structural opening a1, frame 2, and mounting fixtures 4a to 4c, or loading and holding it by tying it to the vertical frame 2a, upper horizontal frame 2b, and lower horizontal frame 2c of the frame 2 with string or the like, and selecting the appropriate method according to the form of each loading position (a) to (d). The method for loading and holding the loading member 7 is not limited to the method described above, as long as it can hold the loading member 7 at each loading position (a) to (d) and does not hinder the expansion of the loading material 5. If the fastening by mounting brackets 4a and 4b is not permanent, permanent fastening of mounting brackets 4a and 4b is performed after loading the loading member 7.

[0016] As shown in Figures 7 and 8(a), an extra-large loading member 7 is placed in the loading position (a) with the widest range on the vertical frame 2a side and the upper horizontal frame 2b side. Furthermore, as shown in Figures 7 and 10(a), a large mounting member 7 is provided at the loading position (a) on the lower horizontal frame 2c side. In other words, when installing at loading positions (a) and (b), the installation work is easy because the extra-large or large loading members 7, which are specified to fit these positions, are simply placed on the left and right sides of the mounting fixtures 4a, 4b, and 4c. As shown in Figure 7, at the loading position (c) of the end corner, one medium-sized loading member 7 is placed vertically and horizontally at the end corner. In other words, the loading member 7 to be installed at mounting position (c) can be easily installed by simply placing one medium-sized loading member 7, which is specified to correspond to this position, vertically and horizontally at the end corners. Furthermore, by making the loading member 7, which is installed at the mounting position (c), correspond to the end corners, such as the one shown in Figure 4(c) above, a loading material 5 with a 45-degree cutout at the corner, a loading material 5 bent at 90 degrees, a loading material 5 with a 45-degree cutout at the corner, or a loading material 5 made into a triangular shape, the installation can be completed with a single loading member 7, making the installation work easy and quick. As shown in Figures 7, 8(a), 9(a), 11(a), and 12(a), a small-sized loading member 7 is placed at the loading position (E) of the mounting fixtures 4a, 4b, and 4c. When loading the loading members 7 into each loading position (a) to (d), ensure that they are evenly distributed so that no gaps are created after the loading material 5 expands.

[0017] At the loading positions (E) of the mounting fixtures 4a, 4b, and 4c, by arranging one small loading member 7 each on the indoor and outdoor sides, the loading material 5 can be inserted into the space s narrowed by the mounting fixtures 4a, 4b, and 4c when it expands. In other words, as shown in the figure, one loading member 7 is loaded each below the frame-side fixing member 41c on the outdoor side and the indoor side, with the bolt 401 of the height adjustment member 40c of the mounting fixture 4c as the boundary (step 3). In this loading configuration, as shown in Figure 14(b), the two loading materials 5 expand to fill the space s, and the loading materials 5 come into contact with each other and join together, enveloping the bolt 401 (step 4 described later). Then, as shown in Figure 14(c), the exposed filling material 5 is covered with tape b (step 5). The same effects as those of the previously described embodiment can be obtained in the loading process of the loading member 7 in this manner.

[0018] (Step 4: See Figures 7-12) Step 4 is the process of releasing the seal on the loading member 7, expanding the loading material 5, and sealing the space s between the frame 2 and the structural opening a1 with the expanded loading material 5. To release the seal on the loading member 7, after confirming that the loading member 7 is installed and uniformly positioned at all loading positions (a) to (d), the seal on the loading member 7 is released by breaking the packaging material 6 of the loading member 7 from the inside using a needle, cutter, or heat. When the seal on the loading member 7 is released, the loading material 5 expands from its compressed state, as shown in Figures 1, 8(b), 9(b), 10(b), 11(b), and 12(b), and the expanded loading material 5 seals the spaces s at each loading position (a) to (d). At this time, the joints of each loading material 5 are smoothed out with a rod-shaped object so that they are aligned with the interior surface of the frame 2.

[0019] (Step 5: See Figures 8-12) Step 5 is a finishing step in which, after the spaces s at each loading position (a) to (d) are sealed with the loading material 5, the entire circumference of the portion of the loading material 5 that is exposed on the interior side is covered with tape (release paper, etc.) b. After the completion of step 5, the series of steps for manufacturing the opening building material 1 is finished.

[0020] Then, through steps 1 to 5, the loading of the filling material 5 is completed, and thereafter, using tape b as a base, including the wall material, Cut off Heating material is blown in and the interior finishing process is carried out (not shown).

[0021] According to this manufacturing method, step 2 allows the opening building material 1 to be placed in the opening of the building structure without welding. Step 3 loads the loading members 7 into each loading position (A) to (D), and Step 4 releases the seal on the loading members 7, thereby automatically loading the loading material 5. Furthermore, since welding is not required, each step of the process can be carried out with the shoji screen 3 fitted into the frame 2. In other words, the manufacturing method of this embodiment is an extremely simple and rapid method compared to manufacturing methods that require welding or filling gaps s with mortar or the like. Therefore, the work efficiency of attaching the opening material 1 to the structural opening a1 can be improved. Furthermore, during dismantling, recycling and separate disposal are easy, making it environmentally friendly.

[0022] [Another example of the arrangement configuration of the loading member 1] As another example of the arrangement configuration of the loading member 7, as shown in Figure 13(a), one of the loading members 7 is placed on the exterior side of the structural opening a1, and the other is placed on the exterior of the upper horizontal frame 2b on the interior side, thereby loading one loading member 7 on the exterior side and one on the interior side (step 3). In this arrangement configuration, as shown in Figure 13(b), the two loading materials 5 expand to fill the space s, and the loading materials 5 come into contact with each other and join together (step 4). Then, as shown in Figure 13(c), the exposed filling material 5 is covered with tape b (step 5). The same effects as the embodiment described above can be obtained by another example 1 of the arrangement configuration of the loading member 7.

[0023] [Another example of the loading configuration of the loading component 2] Figure 14 shows another variation of the loading configuration of the loading member. In this modified configuration, as shown in Figure 14(a), the loading member 7 is arranged on the outer circumference of the lower horizontal frame 2c. In this arrangement, as shown in Figure 14(b), the loading material 5 expands and fills the space s. Then, as shown in Figure 14(c), the exposed filling material 5 is covered with tape b (step 5). The same effects as the embodiment described above can be obtained by another example 2 of the arrangement configuration of the loading member 7.

[0024] 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.

[0025] 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]
