It will be efficiently diffused (efficiently due to the "relatively large surface area") and homogenized over the entire board (entire base material). Therefore, according to the present invention, vibration is strongly applied to a part of the base board (the portion on the inner side of the base board into which the screw is screwed in the prior art), and the screw (the base board) is applied. The screw screwed into the inner side of the wheel) is prevented from coming off due to the strong vibration, and the base material may be separated from the fixing member due to the vibration caused by the shaking or strong wind. , Will be effectively prevented.

Moreover, in the above-mentioned invention, the characteristic portion of the above-mentioned "a plurality of screws is applied from the seam between the respective base boards to the fixing member, and the base board is opposed to or in contact with the seam, respectively. The "step of screwing the seam and the fixing member into the seam and the fixing member so that the end portion or a part of the end face is scraped by the screw" is a conventional "step of screwing a plurality of screws from each base board to the fixing member". Just by continuously adding the same type of screwing work using the same or similar screws (extremely low-priced consumables) as in the process of fixing each base board to the fixing member by screwing into. What can be done, that is, it can be performed with good workability and low cost without requiring special metal fittings and having continuity with the work at the time of construction of the conventional base material. Therefore, according to the above invention, even if a tremor due to an earthquake or a strong wind due to a typhoon occurs, the base material is separated from the fixing member, which is continuous with the work at the time of the conventional base material construction. Therefore, it can be effectively prevented without sacrificing the workability and cost as compared with the conventional construction work of the base material.

Further, in the present invention, when fixing a plurality of base boards serving as a base material for a building wall (including a partition wall for partitioning a room), a ceiling or a floor to a fixing member, first, a plurality of screws are attached. Each base board is fixed to the fixing member by screwing it into the fixing member from each base board, and then a plurality of screws are attached to the fixing member from the seam between the base boards. The seam and the fixing member are screwed into the seam so that a part of the end portion or the end surface of each base board facing or in contact with the seam is scraped by a screw. Therefore, according to the present invention, the end portion (or the end surface thereof) facing or in contact with the seam of each base material board is "cut by the male screw portion of the screw in the process of screwing the screw." "The female screw-shaped part formed by the above" will be formed. As a result, the base boards adjacent to each other or facing each other via the seam are formed by the screw in the seam and the female screw-shaped portion (cut into a female screw shape) formed by being scraped by the male screw portion of the screw. Through the "part with a relatively large surface area"), the vibrations are connected to each other so as to be efficiently transmitted (more efficiently by the portion having the "relatively large surface area"). Become. Therefore, according to the base material constructed according to the present invention, even if shaking due to an earthquake or strong wind due to a typhoon occurs, the vibration due to the shaking or strong wind is screwed into the seam between the base boards. For the plurality of substrates, through the screw and the "female screw-shaped portion formed by being scraped by the male screw portion of the screw (the portion having a" relatively large surface area "scraped in the female screw shape)". It will be efficiently diffused (efficiently due to the "relatively large surface area") and uniformed over the entire board (entire base material). Therefore, according to the present invention, vibration is strongly applied to a part of the base board (the portion on the inner side of the base board into which the screw is screwed in the prior art), and the screw (the base board) is applied. The screw screwed into the inner side of the wheel) is prevented from coming off due to the strong vibration, and the base material may be separated from the fixing member due to the vibration caused by the shaking or strong wind. , Will be effectively prevented.

Moreover, in the above-mentioned invention, the above-mentioned "subsequently, a plurality of screws are inserted from the seam between the base boards to the fixing member, and for each base facing or in contact with the seam," which is a characteristic portion thereof. The "step of screwing the seam and the fixing member into the seam and the fixing member so that the end portion or a part of the end face of the board is scraped by the screw" is a conventionally performed "plurality of screws from each base board. Continuously add the same type of screw fixing work using the same or similar screws (extremely low cost consumables) as in the process of fixing each base board to the fixing member by screwing it into the fixing member. It can be done just by doing it, that is, it can be done with good workability and low cost without requiring special metal fittings and having continuity with the work at the time of construction of the conventional base material. Therefore, according to the above invention, even if a tremor due to an earthquake or a strong wind due to a typhoon occurs, the base material is separated from the fixing member, which is continuous with the work at the time of the conventional base material construction. Therefore, it can be effectively prevented without sacrificing the workability and cost as compared with the conventional construction work of the base material.

Further, in the present invention, the diameter of the portion having the largest cross section (the portion in the vicinity of the head in the male screw portion) perpendicular to the screwing direction of the male screw portion of the screw is 1 of the width dimension of the seam. .When configured to be 5 times or more, in the process of screwing the screw from the seam between the base boards into the fixing member, the base board facing or in contact with the seam, respectively.

Is.

As described above, in the present embodiment, a plurality of base boards (for example, gypsum board) used as a base material for a building wall (including a partition wall for partitioning a room), a ceiling or a floor are provided on the furring strip 3. When fixing to a fixing member such as, first, by screwing a plurality of screws 4 from each gypsum board 1 into the furring strip (fixing member) 3, each gypsum board 1 is screwed into the furring strip (fixing member) 3. After that, a plurality of screws 4 are connected from the seam 2 between the gypsum boards 1 to the furring strip (fixing member) 3, and the end 1a of each gypsum board 1 facing or in contact with the seam 2, respectively. A part of the end face is screwed into the seam 2 and the furring strip (fixing member) 3 so as to be scraped into a female screw shape by the male screw portion 4b (see FIG. 5B) of the screw 4. There is. Therefore, according to the present embodiment, the end portion 1a (or the end surface thereof) facing or in contact with the seam 2 of each gypsum board (base material board) 1 is surely "a male screw portion of the screw 4". The female screw-shaped portion 1b ”(see FIGS. 1 and 2) formed by being scraped by 4b is formed. As a result, the gypsum boards 1 adjacent to each other or facing each other via the seam 2 are formed by the screw 4 in the seam 2 and the female screw-shaped portion formed by being scraped by the male screw portion 4b of the screw 4. Vibrations are efficiently transmitted to each other (efficiently by understanding the portion having the "relatively large surface area") through the "part having a" relatively large surface area "cut into a female screw shape)". So that they are connected to each other. Therefore, according to the base material constructed according to the present embodiment, even if a tremor due to an earthquake or a strong wind due to a typhoon occurs, the vibration due to the tremor or the strong wind is applied to the seam 2 between the gypsum boards 1. Through the screwed screw 4 and "a female screw-shaped portion formed by being scraped by the male screw portion 4b of the screw 4 (a portion having a" relatively large surface area "cut into a female screw shape)". It is efficiently diffused (efficiently due to the "relatively large surface area") and uniformed over the entire gypsum board 1 (the entire base material). Therefore, according to the present embodiment, vibration is strongly applied to a part of the gypsum board 1 (the inner part of the gypsum board 1 into which the gypsum board 1 is screwed in the prior art), and the gypsum 4 (the gypsum board 1). It is possible to prevent the gypsum screwed into the inner part from coming off due to the strong vibration, and as a result, the base material may separate from the fixing member due to the vibration caused by the shaking or strong wind. It will be effectively prevented.

Moreover, in the present embodiment, the characteristic portion of the gypsum board is "a plurality of screws, from the seam 2 between the gypsum boards 1 to the furring strip 3 and facing or in contact with the seam 2, respectively. The step of screwing into the seam 2 and the furring strip 3 so that a part of the end portion 1a (or the end surface thereof) of 1 is scraped by the screw 4 (see the region shown by B in FIG. 6) has been conventionally performed. The "a plurality of screws 4 are screwed from each gypsum board 1 (inner portion of each gypsum board 1) in the direction of the furring strip 3 to fix each gypsum board 1 to the furring strip 3. The same type of gypsum fixing work using the same or similar gypsum 4 (extremely low-priced consumables) as in the step of making gypsum (see the area shown by A in FIG. 6) can be performed simply by continuously adding, that is, a conventional base. It can be done with good workability and low cost without the need for special metal fittings and with continuity with the work at the time of material construction. Therefore, according to the present embodiment, even if a tremor due to an earthquake or a strong wind due to a typhoon occurs, the base material is separated from the fixing member, which is continuous with the work at the time of the conventional base material construction. Therefore, it can be effectively prevented without sacrificing workability and cost as compared with the conventional construction work of the base material.

Further, in the present embodiment, the diameter of the largest portion of the cross section perpendicular to the screwing direction (the portion in the vicinity of the head portion 4a in the male screw portion 4b) of the male screw portion 4b of the screw 4 is the seam. When the width dimension of 2 is 1.5 times or more (more preferably 2 times or more or less, 3 times or more or less, 4 times or more or less, or 5 times or more or less), the screw In the process of screwing 4 from the seam 2 between the gypsum boards 1 into the fixing member 3, the end 1a or a part of the end face of each gypsum board 1 facing or in contact with the seam 2 is a part of the screw. Since the male screw portion 4b of 4 ensures that the screw is cut into a female screw shape, the end portion 1a (or the end surface thereof) facing or in contact with the seam 2 of each base material board 1 is marked with "the male of the screw 4". It has become possible to reliably form a female screw-shaped portion (a portion having a "relatively large surface area" scraped into a female screw shape) formed by being scraped by the screw portion 4b, and as a result, due to an earthquake. A female screw-shaped portion (scraped into a female screw shape) formed by scraping the vibration caused by shaking or a strong wind caused by a typhoon by the screw 4 in the seam 2 and the male screw portion 4b of the screw 4 more reliably. Through the "part having a" relatively large surface area ")", it becomes possible to diffuse and homogenize the whole of the plurality of gypsum boards 1 (the whole of the base material).
