Between the metal upper horizontal beam 5 and the metal lower horizontal beam 6 on the floor side called the lower runner, the metal square column 1 called a stud is erected at appropriate intervals in the longitudinal direction of the horizontal beam, A board material 18 for an upper wall is fixed to both the indoor and outdoor surfaces of the metal square column 1, and a horizontal rail 2 for steadying is attached to each square column 1 in a downward U-shaped posture. It is attached so as to penetrate through the wall, thereby ensuring the robustness of the wall.
[0010]
In this embodiment, the rectangular metal column 1 has a horizontal width dimension a that is, for example, 25 mm perpendicular to the horizontal bars 2, 5, 6, and a horizontal width along the longitudinal direction of the horizontal bars 2, 5, 6. The dimension b is 40 mm. Incidentally, the width dimension a of the rectangular column 11 used for the wall base material shown in FIG. 7 is 45 mm, and the width dimension b is 30 mm.
[0011]
As shown in FIG. 2, the rectangular cylindrical column body 1a of the metallic rectangular cylindrical column 1 bends a metal plate into a rectangular tube shape and bends its opposite edge into a J shape or a U shape. It is formed on the rectangular column 1 by a so-called screw joint structure in which these bent portions are entangled and joined to each other. As shown in FIG. 3, the rectangular cylinder main body 1a has a U-shaped cross section having a U-shaped cross section composed of a web portion 2a and flange portions 2b and 2b at both ends thereof. Openings 7 and 8 for allowing the horizontal rail 2 to be inserted in a laterally U-shaped posture are provided, and both the openings 7 and 8 are formed in substantially the same shape, and one of the openings 7 and 8 is provided. The side opening 7 is a horizontal beam insertion side opening, and the other side opening 8 is a horizontal beam drawer side opening. The horizontal rail 2 for steadying is made of a channel material, the width of the web portion 2a is 36 mm, the flange portion 2b is 11 mm, and the opening portions 7 and 8 of the rectangular column 1 have a vertical width c of 42 mm and a horizontal width. d is set to 15 mm.
[0012]
Of the two openings 7 and 8, the horizontal beam insertion side opening 7 has a pair of retaining pieces 11 and 12 on both left and right edges of the opening that prevent the steady horizontal beam 2 from coming out of the opening 7. As shown in FIG. 2 (A), it protrudes in a manner like a door, and both retaining pieces 11 and 12 are normally hollow in the rectangular column main body 1a as shown in FIG. 2 (B). As shown in FIG. 3, when the horizontal rail 2 for steadying is inserted, as shown in FIG. 3, the horizontal rail 2 is further opened from the half-opened state by elastic deformation. Both the inner and outer surfaces of the web portion 2a are sandwiched between the leading end portions of both retaining pieces 11, 12.
[0013]
In forming the retaining pieces 11, 12, a predetermined cut is made in the opening 7 formation position of the metal plate in the unfolded state before the metal plate is bent into a rectangular tube shape, and the retaining piece 11 is placed in the opening 7. , 12 are removed so that only unnecessary portions are removed, and then the unfolded metal plate is bent into a rectangular tube shape to form a metal rectangular column 1 which is shown in FIG. State. FIG. 2A shows a state in which the retaining pieces 11 and 12 in the opening 7 are forcibly bent toward the hollow portion 1o side of the rectangular column main body 1a and opened in a half-open state from the state of FIG. This is the state shown in (B). The horizontal beam insertion side opening 7 is formed by cutting out into a rectangular shape in a developed state before the metal plate is bent.
[0014]
At both side edges of the opening of the horizontal beam insertion side opening 7, that is, at the bent edges 9, 10, both the retaining pieces 11, 12 are more easily opened from the half-opened state by elastic deformation, and the elastic deformation assisting holes 13. , 14 are provided.
[0015]
Further, as shown in FIG. 2 (A), the retaining pieces 11 and 12 are arranged in the opposite direction in such a manner that they are concavo-convexly fitted from both side edges 9 and 10 of the opening in the lateral beam insertion side opening 7. The maximum protruding length (the length from the opening edge 9 to the tip of the retaining piece 11) of one retaining piece 11 that protrudes and abuts against the inner surface of the web portion 2a of the steadying crosspiece 2 is the other retaining piece. 12 is longer than the protruding length of 12 (the length from the opening edge 10 to the tip of the retaining piece 12). Here, “the two retaining pieces 11 and 12 project in the opposite direction in a form in which the concave and convex pieces are engaged with each other” means that one retaining piece 11 forms a concave portion and the other retaining piece 12 has a convex portion. This means that the retaining pieces 12 that are convex portions are fitted into the retaining pieces 11 that are concave portions, and both the retaining pieces 11 and 12 protrude in the opposing direction. And, as shown in the figure, the retaining piece 11 that is a concave portion has projecting piece portions 11a and 11a having a maximum projecting length on both upper and lower sides in a form that sandwiches the retaining piece 12 therebetween.
[0016]
Accordingly, when the horizontal rail 2 for steadying is inserted into the lateral beam insertion side opening 7, the tip of the projecting pieces 11a and 11a of the retaining piece 11 having a long protruding length is the web of the horizontal rail 2 for steadying. The tip portion of the retaining piece 12 having a short protruding length is elastically contacted to the inner surface side of the portion 2a, and is elastically contacted to the outer surface side of the web portion 2a, and both the inner and outer surfaces of the web portion 2a are sandwiched by these tip portions. .
[0017]
1 embodiment of this invention consists of the above structures, and in order to use this, as shown in FIG. 1, first, the upper crosspiece 5 which is an upper runner is attached to the ceiling surface side by driving in a screw, A lower horizontal beam 6 which is a lower runner is similarly mounted on the floor side by driving in screws, and the metal square cylindrical column 1 according to the present invention called a stud is placed between the upper and lower horizontal beams 5 and 6 at appropriate intervals. After standing upright and accurately regulating the distance between each other, they are also attached to each other by driving in screws. At this time, the retaining pieces 11, 12 provided in the horizontal beam insertion side opening 7 of each rectangular column 1 are forced to the hollow portion 1 o side of the rectangular column main body 1 a, as indicated by phantom lines in FIG. 5. It is bent in a half-open manner and the tip portions of both retaining pieces 11 and 12 cross each other.
[0018]
After that, as shown in FIG. 3, the horizontal rail 2 for steadying is inserted into the rectangular column main body 1a from the horizontal beam insertion side opening 7 of the rectangular column 1 in a laterally U-shaped posture so as to be half-opened. The retaining pieces 11, 12 that are open and intersect with each other are pushed open and pulled out from the side rail drawer side opening 8 through the hollow portion 1 o, and thus the side beam insertion side of the adjacent rectangular column 1 The horizontal rail 2 for steadying is made to penetrate through the plurality of rectangular cylindrical columns 1 so as to be sequentially inserted into and pulled out from the opening 7 and the horizontal beam drawer side opening 8.
[0019]
As described above, when the horizontal rail 2 for steadying is inserted into the rectangular column main body 1a from the horizontal beam insertion side opening 7 of each rectangular column 1, it is opened in a half-open state and the end portion intersects. The pieces 11 and 12 are further opened from the half-opened state by elastic deformation, and both the inner and outer surfaces of the web portion 2a of the steadying horizontal rail 2 are connected to the tips of the stopper pieces 11 and 12 as shown by the solid lines in FIGS. Since the horizontal rail 2 for steadying is fixed to the rectangular column 1 by this, the horizontal rail 2 for steadying is simply inserted into the rectangular column main body 1a from the lateral beam insertion side opening 7 It is possible to reliably and sufficiently exert the function of preventing the steady rail 2 from coming off by a simple operation.
[0020]
In particular, in the metal square cylindrical column 1 of the present invention, the anti-sway cross rail 2 having a U-shaped cross section is formed on the two opposite surfaces across the hollow portion 1o of the rectangular column main body 1a. The openings 7 and 8 to be inserted in a shape are formed, and a pair of retaining pieces 11 and 12 on both sides of the openings 7 and 8 are projected in a manner like a sound door. The both retaining pieces 11 and 12 are normally opened in a half-opened shape toward the hollow portion 1o of the rectangular column main body 1a, and the above described when the anti-sway cross rail 2 is inserted. Since it is further opened by elastic deformation from the half-opened state, both the inner and outer surfaces of the web portion 2a of the steadying crosspiece 2 are sandwiched between the tip portions of the retaining pieces 11, 12, so that a thin metal square tube The pillar 1 can be used, and as shown in this embodiment, the one orthogonal to the cross rails 2, 5, 6 Even in the case of a thin rectangular column having a width dimension a of 25 mm, for example, the steadying crosspiece 2 having a web portion 2a having a width of 36 mm larger than the width dimension a of the rectangular cylinder column 1 is easily inserted. Can be made.
[0021]
Further, both the retaining pieces 11, 12 protrude in the opposite direction from the opening side edges 9, 10 in the horizontal beam insertion side opening 7 so as to be engaged with each other, and the web portion 2 a of the steadying horizontal beam 2. Since the protruding length of one retaining piece 11 abutting against the inner surface is longer than the projecting length of the other retaining piece 12, the lateral width d of the lateral beam insertion side opening 7 can be made as narrow as possible. It is possible to minimize the backlash of the side rail 2 for steadying in the portion 7 and to securely clamp and fix both the inner and outer surfaces of the web portion 2a at the tip portions of the retaining pieces 11 and 12, as described above. Since the horizontal width d of the horizontal beam insertion side opening 7 can be reduced as much as possible, the horizontal beam insertion side opening 7 can be easily formed even with a thin metal square cylindrical column 1.
[0022]
FIG. 6 shows another embodiment of both retaining pieces 11, 12 formed in the lateral beam insertion side opening 7 of the square prism column 1 made of metal. That is, the both retaining pieces 11 and 12 in the above-described embodiment are the retaining pieces 12 having a short protruding length, but in the embodiment shown in FIG. 6, the retaining pieces 12 having a short protruding length are formed. Is slightly different in that it is divided into upper and lower parts, and the rest is almost the same as the previous embodiment.
[0023]
【The invention's effect】
According to the first aspect of the present invention, the width of the web portion of the anti-sway horizontal beam is the same as that of the metal rectangular column even if the horizontal square dimension perpendicular to the horizontal beam is small and thin. It is possible to easily insert a steady rail that is larger than the width dimension.
[0024]
In addition, by inserting the horizontal rail for steadying into the square tube main body from the opening on the side of the metal square tube column into the side of the square tube column, the retaining piece opened in a half-open state is further opened from the half-open state by elastic deformation. Then, both the inner and outer sides of the web part of the anti-sway horizontal bar are sandwiched between the leading ends of the anti-slip pieces, so that the anti-sway horizontal bar is fixed to the rectangular column. The horizontal beam for steadying can be attached by simply inserting the horizontal beam into the rectangular column main body from the opening on the side where the horizontal beam is inserted, improving work efficiency and preventing the horizontal beam for steadying from coming off. Can be fully exhibited.
Furthermore, according to the present invention, the lateral width of the lateral beam insertion side opening can be made as narrow as possible, the backlash of the horizontal rail within the opening can be reduced as much as possible, and the web portion can be Both the inner and outer surfaces can be securely clamped and fixed, and the opening on the side rail insertion side can be easily formed even with a thin metal square cylindrical column .
[0025]
According to the second aspect of the invention, the steadying horizontal beam is inserted into the rectangular column main body from the horizontal beam insertion side opening of the metal rectangular tube column, and is protruded from the left and right edges of the opening. When the two retaining pieces are further released from the half-opened state by elastic deformation, the retaining pieces can be pushed open by lightly inserting the steadying horizontal beam. Insertion work becomes easy and work efficiency can be further improved.
