Description

Technical Field

[0001] The present invention relates to the technical field of a screw fixing structure and a screw fixing method for an upper frame in a partition for partitioning an indoor space.

Background Art

[0002] Generally, in order to partition an indoor space, a partition may be installed between the floor surface and the ceiling surface. Among such partitions, there is one in which an inter-column space is formed on the ceiling side of a panel body for partitioning the indoor space. The inter-column space is configured as a four-sided frame surrounded by left and right vertical frames (vertical columns), an upper frame (upper horizontal frame) attached to the ceiling surface side, and a blind frame (blind, lower horizontal frame) provided in a spanning manner between the left and right vertical frames. And in such a case, there is known a structure in which the upper frame is simply attached by being locked to a ceiling rail provided on the ceiling surface (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the conventional structure, since the upper frame is supported by the lattice board incorporated in the inter-column space, it does not cause much problem. However, when the lattice board is not incorporated, there is no support for the upper frame. Therefore, it is assumed that the upper frame simply locked to the ceiling rail may inadvertently become disengaged from the ceiling rail and fall off in the event of, for example, an earthquake. Therefore, in order to cope with such a situation, an attempt is made to screw-fix the upper frame to the ceiling material (ceiling board) via screws (bolts, screws) to prevent inadvertent falling off. However, when the upper frame is configured to include front and rear locking piece portions formed with locking portions that lock to a ceiling rail attached to the ceiling surface, and a lower frame piece portion that connects the locking piece portions with a gap therebetween vertically with respect to the ceiling rail, as shown in Fig. 8(A), there is a risk that the lower frame piece portion 6b of the upper frame 6, which becomes the lower frame piece portion against which the screw head 7b abuts due to over-tightening (excessive screwing in) of the screw 7, may be deformed in a state of being recessed toward the ceiling surface H. For this reason, when screw-fixing the upper frame to the ceiling material side, it is necessary to perform careful work so as not to have such over-tightening. However, it is difficult to perform such careful work for all screws, and there are problems such as poor workability, and these are the problems to be solved by the present invention.

Means for Solving the Problems

[0005] The present invention was created for the purpose of solving these problems in view of the above circumstances. The invention according to claim 1 is an upper frame which is a ceiling-side component of a partition provided for partitioning an indoor space front and rear. The upper frame has front and rear frame pieces formed with locking portions that lock to a ceiling rail attached to the ceiling surface front and rear, and a lower frame piece that connects the front and rear frame pieces of the upper frame with a gap therebetween vertically with respect to the ceiling rail. When screw-fixing the upper frame to the ceiling side via a screw screwed in from the lower frame piece, a spacer for preventing deformation of the upper frame due to over-screwing of the screw is arranged in the gap, which is a screw-fixing structure for the upper frame in the partition. The invention according to claim 2 is characterized in that the spacer has a cylindrical shape through which the screw portion of the screw passes, the upper edge portion abuts against the lower surface of the ceiling rail, and the lower edge portion passes through a through-hole formed in the lower frame piece of the upper frame in a state of abutting against the upper surface of the screw head, which is a screw-fixing structure for the upper frame in the partition according to claim 1. The invention according to claim 3 is characterized in that the spacer has a cylindrical shape through which the screw portion of the screw passes, the upper edge portion passes through a through-hole formed in the ceiling rail and abuts against the ceiling surface, and the lower edge portion abuts against the upper surface of the lower frame piece of the upper frame, which is a screw-fixing structure for the upper frame in the partition according to claim 1. The invention according to claim 4 is the screw fixing structure of the upper frame in the partition according to claim 1, characterized in that the spacer has a cylindrical shape through which the threaded portion of the screw passes, the upper edge portion abuts against the lower surface of the ceiling rail, and the lower edge portion abuts against the upper surface of the lower piece portion of the upper frame. The invention according to claim 5 is the screw fixing structure of the upper frame in the partition according to claim 1, characterized in that the spacer has a cylindrical shape through which the threaded portion of the screw passes, the upper edge portion passes through the through hole formed in the ceiling rail and abuts against the ceiling surface, and the lower edge portion passes through the through hole formed in the lower piece portion of the upper frame in a state of abutting against the upper surface of the screw head. The invention according to claim 6 is the screw fixing structure of the upper frame in the partition according to claim 1, characterized in that the spacer has a cylindrical shape through which the threaded portion of the screw passes, and is set to a length from the lower surface of the ceiling rail to the lower surface of the lower piece portion of the upper frame. The threaded portion is set to be longer than the length from the lower surface of the ceiling rail to the lower surface of the lower piece portion of the upper frame and is screwed into the ceiling portion. The lower piece portion of the upper frame has a through hole with a diameter smaller than that of the screw head but through which the spacer passes. The invention according to claim 7 is that the upper frame forms an inter-column space together with the lower non-ruled frame. A concave groove for fitting and attaching the upper edge portion of the panel plate for the inter-column is formed in the middle portion in the front-rear direction of the lower piece portion of the upper frame, and a through hole for passing the spacer is formed in the groove bottom plate portion of the concave groove. It is the screw fixing structure of the upper frame in the partition according to claim 6, characterized by the above. The invention according to claim 8 is a method of screwing and fixing an upper frame, which is a ceiling-side component of a partition provided for partitioning an indoor space back and forth, to a ceiling rail attached to a ceiling surface. The upper frame is configured to include front and rear upper frame pieces each having a locking portion formed thereon for locking to the ceiling rail in the front and rear directions, and a lower upper frame piece for connecting the front and rear upper frame pieces with a gap therebetween in the vertical direction with respect to the ceiling rail. The method is a method of screwing and fixing the upper frame to the ceiling side using a cylindrical spacer through which a screw portion of a screw is inserted. When the upper frame is not yet incorporated into the ceiling rail, the method sequentially performs a step of drilling a through hole for penetrating the spacer in the lower upper frame piece of the upper frame, and a step of incorporating the upper frame with the through hole drilled therein into the ceiling rail. When the upper frame is already incorporated into the ceiling rail, the method performs a step of drilling a lower hole for inserting the screw portion through the through hole in the ceiling rail, and a step of screwing a screw with the screw portion inserted through the spacer until the upper edge of the spacer abuts against the lower surface of the ceiling rail and the upper surface of the screw head abuts against the lower edge of the spacer and screwing is no longer possible. This is a method of screwing and fixing the upper frame in a partition, characterized in that each of the above steps is sequentially performed.

Advantages of the Invention

[0006] By adopting the invention according to claim 1, when screwing and fixing the upper frame to the ceiling side to prevent accidental detachment of the upper frame, a spacer can be disposed in the gap between the ceiling rail and the lower upper frame piece of the upper frame to prevent excessive screwing of the screw. As a result, the screwing and fixing operation of the upper frame can be performed simply and reliably, improving workability. By adopting the invention according to claim 2 or 8, when screwing a screw to support the upper frame on the ceiling side, when the upper edge of the spacer disposed in the gap between the ceiling rail and the lower upper frame piece abuts against the lower surface of the ceiling rail and the upper surface of the screw head abuts against the lower edge of the spacer penetrating the through hole formed in the lower upper frame piece, further screwing of the screw becomes impossible, restricting excessive screwing of the screw, and enabling simple and reliable screwing and fixing of the upper frame in a state where deformation of the upper frame is prevented. According to the invention of claim 3, when screwing in a screw to support the upper frame on the ceiling side, at the stage where the upper edge portion of the spacer disposed in the gap between the ceiling rail and the lower piece portion of the upper frame penetrates through the through hole formed in the ceiling rail and abuts against the ceiling surface, and the lower edge portion of the spacer abuts against the upper surface of the lower piece portion of the upper frame, further screwing in of the screw becomes impossible, thus restricting over-screwing of the screw, and enabling easy and reliable screw fixation of the upper frame in a state where deformation of the upper frame is prevented. According to the invention of claim 4, when screwing in a screw to support the upper frame on the ceiling side, at the stage where the upper edge portion of the spacer disposed in the gap between the ceiling rail and the lower piece portion of the upper frame abuts against the lower surface of the ceiling rail, and the lower edge portion of the spacer abuts against the upper surface of the lower piece portion of the upper frame, further screwing in of the screw becomes impossible, thus restricting over-screwing of the screw, and enabling easy and reliable screw fixation of the upper frame in a state where deformation of the upper frame is prevented. According to the invention of claim 5, when screwing in a screw to support the upper frame on the ceiling side, at the stage where the upper edge portion of the spacer disposed in the gap between the ceiling rail and the lower piece portion of the upper frame penetrates through the through hole formed in the ceiling rail and abuts against the ceiling surface, and the upper surface of the screw head abuts against the lower edge portion of the spacer, further screwing in of the screw becomes impossible, thus restricting over-screwing of the screw, and enabling easy and reliable screw fixation of the upper frame in a state where deformation of the upper frame is prevented. By adopting the invention of claim 6, when screwing a screw to support the upper frame on the ceiling side, the length of the spacer disposed in the gap between the ceiling rail and the lower part of the upper frame from the lower surface of the ceiling rail to the lower surface of the lower part of the upper frame, the screw part is set to be longer than the length from the lower surface of the ceiling rail to the lower surface of the lower part of the upper frame and is screwed into the ceiling part. As a result, the lower part of the upper frame has a through hole that is smaller in diameter than the screw head but through which the spacer passes. When screwing a screw to support the upper frame on the ceiling side, the upper edge of the spacer disposed in the gap between the ceiling rail and the lower part of the upper frame abuts against the lower surface of the ceiling rail, and when the upper surface of the screw head abuts against the lower edge of the spacer passing through the through hole formed in the lower part of the upper frame, further screwing of the screw becomes impossible, thereby restricting over-screwing of the screw and enabling simple and reliable screw fixation of the upper frame in a state where deformation of the upper frame is prevented. By adopting the invention of claim 7, the upper frame forms an inter-column space together with the lower frameless frame. A concave groove for an inter-column panel plate is formed in the middle part in the front-rear direction of the lower part of the upper frame, and a through hole for passing the spacer is formed in the groove bottom part of the concave groove. As a result, it becomes possible to simply and reliably perform screw fixation to the ceiling side in a state where deformation of the upper frame is prevented by using the concave groove for attaching the inter-column panel plate.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, 1 is an intermediate partition that partitions the indoor space back and forth. The intermediate partition 1 includes a plurality of vertical columns (vertical frames) 2 that are erected in a state of being adjacent to each other on the left and right between the ceiling surface H and the floor surface F, a panel body for the partition (which may be a door in some cases) 3 incorporated between the adjacent left and right vertical columns 2, a seamless frame (seamless, intermediate horizontal frame) 4 assembled to the middle part in the vertical direction of the left and right vertical columns 2 in a state where the upper edge part of the panel body 2 for the partition is incorporated, a ceiling rail 5 attached to a ceiling material (for example, a ceiling board) 9 whose lower surface is the ceiling surface H via screws (screws) 5a, and an upper frame 6 attached in a state of being locked to the ceiling rail 5. And an inter-column space R surrounded in a rectangular frame shape by the left and right vertical columns 2, the upper frame 6, and the seamless frame 4 is formed in the upper part of the partition 1. And in the present embodiment, no partition plate (partition panel body) is incorporated in the inter-column space R. Since the further details of the partition 1 configured in this way are the same as those of the conventional one except for the structure of the upper frame 6 part described later, they will be omitted.

[0009] The ceiling rail 5 has a substantially U-shaped cross-section and is composed of a rail upper piece part 5b fixed to the ceiling material 9 via screws 5a in a state of abutting against the ceiling surface H, and rail front and rear piece parts 5c provided in a state of hanging down from the front and rear edge parts of the rail upper piece part 5b. More specifically, the upper part 5b of the rail is attached to the ceiling surface H by the screw 5a in a state where the upper middle part 5d formed at the intermediate part in the front-rear direction (the central part in the front-rear direction in this embodiment, but it may be an intermediate part biased in the front or rear direction) abuts against the ceiling surface H. Upper front and rear parts 5e are formed on both the front and rear sides of the upper middle part 5d, and the upper front and rear parts 5e are provided in a state of being separated from the ceiling surface H with a slight gap. Incidentally, it goes without saying that the entire upper part 5b of the rail including the upper front and rear parts 5e may be in contact with the ceiling surface H as the ceiling rail 5.

[0010] Also, the front and rear parts 5c of the rail are formed in a vertical plate shape extending vertically from the front and rear edge parts in the front-rear direction of the upper front and rear parts 5e, and include a front and rear upper side part 5f extending upward from the upper front and rear parts 5e and having an upper edge in contact with the ceiling surface H, and a front and rear lower side part 5g hanging down long from the upper front and rear parts 5e. By being configured in this way, the ceiling rail 5 has a substantially U-shaped form as described above. Furthermore, on the front and rear lower side parts 5g, a front and rear bent part 5h bent inward in the front-rear direction from the lower edge and a rail side locking part 5i protruding inward in the front-rear direction from the intermediate part in the vertical direction (the upper intermediate part in this embodiment) are formed.

[0011] On the other hand, the upper frame 6 has a substantially C-shaped form with an open upper side, and includes an upper frame lower part 6b in which a concave groove 6a with an open lower side is formed at the intermediate part in the front-rear direction (the central part in the front-rear direction in this embodiment, but it may be an intermediate part biased in the front or rear direction), upper frame front and rear parts 6c provided upward from both the front and rear edge parts of the upper frame lower part 6b, and an upper frame upper part 6d bent inward in the front-rear direction from the upper edge of the upper frame front and rear parts 6c and having a gap between the tip edges set larger than the front and rear gap of the concave groove 6a. By being configured in this way, the upper frame front and rear parts 6c are connected to each other at the lower edge parts by the upper frame lower part 6b.

[0012] More specifically, lower side front and rear portions 6e are formed on both front and rear sides of the concave groove 6a in the lower piece portion 6b of the upper frame, and upper frame side locking portions 6f are protrudingly formed on the outer surface in the front-rear direction of the front and rear piece portions 6c of the upper frame. And the front and rear piece portions 6c of the upper frame are set to be insertable from below into the front and rear piece portions 5c of the rail in a state of being in sliding contact or close proximity to the front edge of the front and rear piece bending portions 5h formed in the front and rear piece portions 5c of the rail. In the state where the front and rear piece portions 6c of the upper frame are inserted and incorporated into the front and rear piece portions 5c of the rail, the upper piece portion 6d of the upper frame abuts against the front and rear portions 5e of the upper piece, the lower side front and rear portions 6e are flush with the front and rear piece bending portions 5h, and a gap S is provided between the upper piece portion 5b of the rail and the lower piece portion 6b of the upper frame and they are spaced apart vertically. In this incorporated state, the upper frame side locking portion 6f will be positioned above and lock by forcibly fitting over the rail side locking portion 5i, whereby the upper frame 6 is locked to the ceiling rail 5, and a configuration is provided for restricting the downward movement of the upper frame 6 in its natural state (normal state).

[0013] When screw-fixing the upper frame 6 incorporated in the ceiling rail 5 to the ceiling material 9 side via screws (bolts) 7, a cylindrical spacer 8 through which the screw portion 7b of the screw 7 penetrates is arranged in the gap S between the upper piece portion 5b of the rail and the lower piece portion 6b of the upper frame. First, in the case of this embodiment, the spacer 8 penetrates from below through a through hole 6h drilled in the groove bottom piece portion 6g of the concave groove 6a constituting the lower piece portion 6b of the upper frame. In the state of such penetration, the screw portion 7b of the screw 7 inserted through the spacer 8 and protruding from the upper edge portion 8a is screwed into the ceiling board 9 through a lower hole 5j provided in the upper middle portion 5d constituting the upper piece portion 5b of the rail. In this case, when the screw 7 is screwed in until the upper edge portion 8a of the spacer 8 abuts against the upper middle portion 5d and the upper surface (the upper surface of the screw head 7a when the screw 7 is screwed in upward from below (the surface on the screw portion 7b side)) 7c of the screw head 7a abuts against the lower edge portion 8b of the spacer 8, further screwing in becomes impossible, and in this state, the screw-fixing operation of the upper frame 6 to the ceiling material 9 side is completed.

[0014] Then, with the spacer 8 intervening in the gap S in this way, the upper frame 6 is screwed and fixed to the ceiling material 9 via the screw 8. As a result, the upper edge portion 8a of the spacer 8 abuts against the lower surface of the upper rail portion 5b of the ceiling rail 5, specifically, the lower surface of the middle upper portion 5d that abuts against the ceiling surface H, and the lower edge portion 8b abuts against the upper surface 7c of the screw head portion 7a of the screw 7. In this state, the lower edge portion 8b of the spacer 8 that passes through the through hole 6h provided in the groove bottom plate portion 6g constituting the lower piece portion 6b of the upper frame is flush with the upper surface 7c of the screw head portion 7a and abuts against the lower surface of the groove bottom plate portion 6g, forming a support structure for the upper frame 6 that can prevent deformation due to excessive screwing of the upper frame 6.

[0015] And as a method for performing the operation of screwing and fixing the upper frame 6 to the ceiling material 9 in this way, the following method is executed. In that case, when the upper frame 6 is before being incorporated into the ceiling rail 5, · A step of drilling a through hole 6h for passing the spacer 8 through the groove bottom plate portion 6g of the upper frame 6 before incorporation. · A step of incorporating the upper frame 6 with the through hole 6h drilled into the ceiling rail 5. are sequentially executed. On the other hand, when the upper frame 6 is already incorporated into the ceiling rail 5, · A step of drilling a through hole 6h for passing the spacer 8 through the groove bottom plate portion 6g of the upper frame 6 incorporated into the ceiling rail 5. is executed. And after the upper frame 6 with the through hole 6h formed is incorporated into the ceiling rail 5, · A step of drilling a lower hole 5j for inserting the screw portion 7b through the upper middle portion 5d of the ceiling rail 5 using a drilling tool such as a drill from the through hole 6h of the upper frame 6 incorporated into the ceiling rail 5. · A step of screwing the screw 7 inserted into the spacer 8 in a state of being inserted through the through hole 6h toward the ceiling side until the upper edge portion 8a of the spacer 8 abuts against the lower surface of the upper middle portion 5d and the lower edge portion 8b abuts against the upper surface 7c of the screw head portion 7a and no further screwing is possible. They are sequentially executed, and in this way, it is configured to be able to screw-fix the upper frame 6 to the ceiling material 9 in a state where deformation is prevented as described above. And in this case, the process of drilling the lower hole 5j is carried out using a drilling tool such as a drill from the through hole 6h in a state where the upper frame 6 having the through hole 6h drilled in the ceiling rail 5 is assembled. Therefore, there is no fear that the through hole 6h and the lower hole 5j are misaligned as in the case of drilling the lower hole 5j in the ceiling rail 5 before attaching the upper frame 6, and the drilling operation can be performed in a well-aligned state.

[0016] In the present embodiment configured as described above, when screwing the screw 7 to screw-fix the upper frame 6 to the ceiling material 9, the spacer 8 disposed in the gap S between the upper rail part 5b of the ceiling rail 5 and the lower part 6b of the upper frame prevents the lower part 6b of the upper frame from being deformed and biased toward the ceiling rail 5, and screw-fixing can be performed easily and surely.

[0017] That is, in this case, with the spacer 8 penetrating the through hole 6h formed in the bottom part 6g of the groove of the concave groove 6a formed in the lower part 6b of the upper frame, the screw part 7b of the screw 7 inserted into the spacer 8 is inserted into the lower hole 5j provided in the ceiling rail 7, and further screwed into the ceiling material 9. When the screwing operation of the screw 7 becomes impossible, the upper edge part 8a of the spacer 8 abuts against the lower surface of the middle part 5d of the upper part, which is the upper rail part 5b of the ceiling rail, and the upper surface 7c of the screw head 7a abuts against the lower edge part 8b of the spacer 8 penetrating the through hole 6h. And in this state, the upper surface 7c of the screw head 7a abuts against the lower surface of the bottom part 6g of the groove, and the screw-fixing state of the upper frame 6 to the ceiling side is achieved. Further screwing of the screw 7 is impossible, and over-screwing of the screw 7 is restricted, and screw-fixing of the upper frame 6 can be performed easily and surely in a state where deformation of the upper frame 6 is prevented.

[0018] And when performing the screw fixing operation of the upper frame 6 as described above, as a procedure, when the upper frame 6 is before being incorporated into the ceiling rail 5, after drilling a through hole 6h in the upper frame 6, the upper frame 6 will be incorporated into the ceiling rail 5. Also, when the upper frame 6 is already incorporated into the ceiling rail 5, a through hole 6h is drilled in the incorporated upper frame 6. Then, a lower hole 5j is drilled in the ceiling rail 5 from the through hole 6h of the incorporated upper frame 6 using a drilling tool such as a drill. The screw 7 inserted into the spacer 8 in a state of being inserted through the through hole 6h is screwed into the ceiling material 9 through the lower hole 5j until it cannot be screwed any further. As described above, the upper edge portion 8a of the spacer 8 abuts against the lower surface of the upper middle portion 5d which is the upper rail upper piece portion 5b of the ceiling rail, and the upper surface 7c of the screw head 7a abuts against the lower edge portion 8b of the spacer 8 passing through the through hole 6h, resulting in a screw-fixed state of the upper frame 6. This eliminates the need for adjustment during the troublesome screwing operation of the screw 7, enabling a simple and reliable screw fixing operation.

[0019] Incidentally, the concave groove 6a formed in the upper frame 6 of the present embodiment is configured such that an intermediate panel plate 10 for the railing composed of a thin plate material such as a glass plate can be incorporated as shown in FIG. 8(B). And even in the case where the intermediate panel plate 10 for the railing is incorporated in this way, when it is desired to perform attachment reinforcement by screw-fixing the upper frame 6, screw fixing to the ceiling side can be performed using the screw 7 and the spacer 8 in the same manner as in the above-described embodiment. Furthermore, the upper frame 6 of the present embodiment is incorporated into the ceiling rail 5 so that the lower part 6b of the upper frame abuts against the upper part 5b of the rail, with the top and bottom reversed compared to the previous case, as shown in Fig. 8(C). In this case, the upper part 6d of the upper frame will be positioned on the lower side. In this situation, a thick partition plate 11 such as a panel body can be incorporated into the gap between the leading edge portions of the upper part 6d of the upper frame, which is wider than the concave groove 6a. The upper frame 6 of the present embodiment is designed to be usable in both such configurations. Incidentally, if it is desired to reinforce the attachment of the upper frame 6 in this state, a screw 7d can be screwed in from the bottom part 6g of the groove. In this case, due to the fact that the bottom part 6g of the groove is close to the ceiling surface H and the concave groove 6a is narrow, excessive screwing in of the screw 7d is avoided, and it is not necessary to provide a spacer except in particularly required cases.

[0020] Note that the present invention is not limited to the above-described embodiment. As for the arrangement structure of the spacer 8 disposed in the gap S between the upper part 5b of the rail of the ceiling rail 5 and the lower part 6b of the upper frame, there is one as shown in Fig. 7. As shown in Fig. 7(A), when the upper frame 6 is fixed with screws by screwing the screws 7 until they cannot be screwed in any further, the upper edge portion 8a of the spacer 8 passes through the through-hole 5k formed in the ceiling rail 5 and abuts against the ceiling surface H, and the lower edge portion 8b abuts against the upper surface of the lower part 6b of the upper frame. Also, as shown in Fig. 7(B), when the upper frame 6 is fixed with screws by screwing the screws 7 until they cannot be screwed in any further, the upper edge portion 8a of the spacer 8 abuts against the lower surface of the upper part 5b of the rail, and the lower edge portion 8b abuts against the upper surface of the lower part 6b of the upper frame. Furthermore, as shown in Fig. 7(C), when the upper frame 6 is fixed with screws by screwing the screws 7 until they cannot be screwed in any further, the upper edge portion 8a of the spacer 8 passes through the through-hole 5k formed in the ceiling rail 5 and abuts against the ceiling surface H, and the lower edge portion 8b passes through the through-hole 6h formed in the lower part 6b of the upper frame in a state where it abuts against the upper surface 7c of the screw head 7a.

In a partition configured to include an upper frame front and rear piece part formed with a locking part for locking in the front and rear directions to a ceiling rail attached to the ceiling surface, which is a ceiling side component of the partition provided for partitioning the indoor space front and rear, and an upper frame lower piece part for connecting the upper frame front and rear piece parts with a gap in the vertical direction between the upper frame front and rear piece parts and the ceiling rail, a screw fixing method for fixing the upper frame to the ceiling side using a cylindrical spacer through which the screw part of the screw is inserted, the method comprising: When the upper frame is before being incorporated into the ceiling rail, - A step of drilling a through hole for penetrating the spacer in the lower part of the upper frame of the upper frame; - A step of incorporating the upper frame with the through hole drilled into the ceiling rail; are sequentially executed. When the upper frame is incorporated into the ceiling rail, - A step of drilling a through hole for penetrating the spacer in the lower part of the upper frame of the upper frame; is executed. Further thereafter, - A step of drilling a lower hole for inserting the screw part through the through hole in the ceiling rail; - A step of screwing in a screw with the screw part inserted into the spacer inserted through the through hole until the upper edge of the spacer abuts against the lower surface of the ceiling rail and the upper surface of the screw head abuts against the lower edge of the spacer and cannot be screwed in any further; The screw fixing method of the upper frame in the partition is characterized in that each of the steps is sequentially executed.
