DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a metallic prismatic column main body 1 is formed by drawing out a metallic material such as a galvanized steel plate, or by bending a metallic plate into a rectangular tube shape and opposing edges thereof. Is bent into a J-shape or a U-shape, and these bent ends are entangled with each other to be connected to each other so as to be formed on the metal square tubular main body 1 by a so-called hazel structure or the like. Openings 6 and 7 having a concentric and substantially the same shape are notched and formed on two opposing surfaces of the metal prismatic column main body 1, and one of the openings 6 is used as an opening on the side of a horizontal bar. , The other opening 7
Is an opening at the side of the horizontal rail.

The lower portions of both openings 6 and 7 are provided with horizontal rail fitting grooves 4.
5, the fitting grooves 4 and 5 are formed concentrically,
Therefore, the bottom surfaces 4a and 5a of the two fitting grooves 4 and 5 are formed in a horizontal plane concentric with each other, and the two fitting grooves 4 and 5 substantially match the width of the anti-sway horizontal bar 2 fitted into the grooves. The width of the surplus open portion 15 above the fitting groove 5 of the horizontal rail drawer side opening 7 is formed to be wider than the groove width of the fitting groove 5. Boundary edges 16, 16 between the opening 15 and the fitting groove 5 are inclined.

The anti-sway horizontal rail 2 is made of a metal material such as a substantially U-shaped galvanized steel plate having a channel shape as shown in the figure.

The upper edge of the fitting groove 4, that is, one side edge of the insertion opening 17 for inserting the horizontal rail 2, is located in the horizontal rail insertion side opening 6 of the two openings 6, 7. A retaining piece 9 is protruded from 8 in a manner like a one-sided door. As shown in FIG. 1, particularly FIG. 2, the retaining piece 9 has one side edge 8 of the opening as a bent open portion.
Is always open to the hollow portion 3 side of the metal prismatic cylinder 1 in a half-open state, for example, by being bent at about 45 ° in plan view, and furthermore, due to the elasticity inherent to the metal material of the metal prismatic cylinder main body 1, As shown by the dashed line in the drawing, the half-open state can be further opened by elastic deformation.

Further, the retaining piece 9 is moved from its half-open state to one side edge of the opening of the side-bar insertion side opening 6, more precisely, to the bent opening 8 which is one side edge of the insertion opening 17. Further, there is provided a through hole 10 for assisting elastic deformation so as to assist opening by elastic deformation.

The retaining piece 9 has an opening-side edge that extends from the upper insertion opening 17 to the lower fitting groove 4.
Is formed on the inclined edge 11 so that the opposing interval becomes narrower. Therefore, the retaining piece 9 has a wider width at the lower edge 9a facing the fitting groove 4 and the upper edge 9b at the opposite side.
Are formed to be narrow.

Further, elastic projections 12a and 12b for pressing the left and right side surfaces 2a and 2a of the horizontal rail 2 are provided on both side edges of the fitting groove 4 of the horizontal rail insertion side opening 6, and both of them are projected. Cuts 13a, 13b into which the left and right side pieces 2b, 2b of the horizontal bar 2 enter are formed on the upper edge side of the elastic projections 12a, 12b, and the horizontal bar 2 faces the cuts 13a, 13b.
Locking edge 14 at which the upper end surfaces 2c, 2c on both the left and right sides are locked
a, 14b are formed.

As shown in FIG. 1, and particularly FIGS. 3 (a), 3 (c) and 3 (d), of the elastic projections 12a and 12b, the elastic projection 12a on the side where the retaining piece 9 is projected is formed. The protrusion amount is slightly larger than the other elastic protrusion 12b,
Similarly, of the two cuts 13a and 13b, the cut 13a on the side where the retaining piece 9 protrudes is the other cut 1a.
3b, the depth of cut is slightly larger than that of 3b. Similarly, of the locking edges 14a, 14b, the locking edge 14a on the side where the retaining piece 9 protrudes is the other locking edge 14b. The locking area is formed slightly larger than that. As a result, the horizontal bar 2 is fitted into the fitting groove 4 and is easily locked as described later.

One embodiment of the present invention has the above structure. To use this, as shown in FIG. 4, first, an upper runner, that is, a metal upper cross bar 18 is attached to the ceiling slab side. A lower runner, that is, a lower metal cross bar 19 is also mounted on the floor side by driving a screw into the floor, and a metal square column according to the present invention called a stud between both cross bars 18 and 19. 1 are erected at appropriate intervals so that the openings 6 and 7 are oriented in the longitudinal direction of the horizontal rail, and after precisely regulating the interval between them, they are attached to each other by driving in screws.

Thereafter, as shown by the solid line in FIG. 3C, the anti-sway horizontal rail 2 is oriented vertically, that is, the web 2 e of the channel material of the horizontal rail 2 is oriented in the direction of the retaining piece 9. 1 and 2 so that the retaining piece 9 is turned sideways so as to fit into the opening 2d, and as shown by an arrow P in FIG. 7, the horizontal rail insertion side opening 6 is inserted into the metal prismatic column main body 1 through the hollow part 3, and the horizontal rail drawer side opening 7
, And are sequentially inserted into and pulled out from the adjacent lateral beam insertion side opening 6 and the lateral beam extraction side opening 7 of the metal prismatic column main body 1. At the time of insertion and withdrawal of the steady rest horizontal bar 2 into both openings 6 and 7, the insertion opening 17 and the surplus opening 15 are appropriately formed wider than the fitting grooves 4 and 5. Horizontal beam 2 for steady rest
Can be easily inserted into the openings 6 and 7 and pulled out.

The feature of the present invention is as follows.
At the time of insertion of the sway-preventing horizontal bar 2 into the horizontal-bar insertion-side opening 6, the horizontal bar 2 collides with and presses against the retaining piece 9 protruding from one side edge 8 of the insertion opening 17. However, as shown in FIG. 1, especially FIG.
It is a one-sided opening, and one side edge 8 of the opening is bent open to the hollow portion 3 side of the metal prismatic column 1 at all times, and the metal prismatic cylinder main body is opened. Because of the elasticity inherent to the metal material 1, the half-opened state can be further opened by elastic deformation, so that the retaining piece 9 is further bent from the half-opened state by the pressing action of the anti-sway horizontal bar 2. Due to the elastic deformation of the opening portion 8, the retaining piece 9 is opened as shown by the dashed line in the figure. Therefore, when the steady-holding horizontal bar 2 is inserted into the horizontal-bar insertion-side opening 6, it comes out one by one. Since it is not necessary to bend the stopper piece 9 at the bending opening part 8 and open it, the on-site construction can be simply performed.

Thus, the horizontal rails 2 for anti-sway are placed sideways in the fitting grooves 4, 5 of the openings 6, 7 of all the metal prismatic column main bodies 1, which are erected at a constant interval in the longitudinal direction of the horizontal rails (ie, in the horizontal direction). As shown in FIG. 1 or FIG. 3 (d), the opening 2d of the channel material is fitted upward or downward). In this case, since the guide hole is guided from the wide insertion opening 12 to the inclined edge 11 and fitted into the narrow fitting grooves 4 and 5,
The anti-sway horizontal rail 2 can be easily fitted into the fitting grooves 4 and 5, and the fitting grooves 4 and 5 are formed to have substantially the same width as the anti-sway horizontal rail 2. The horizontal rail 2 is restricted by the fitting grooves 4 and 5 and does not rattle in the indoor and outdoor directions.
Further, since the bottoms 4a and 5a of the fitting grooves 4 and 5 are formed in concentric horizontal planes, the horizontal rails 2 for steadying can be reliably arranged in a horizontal state.

Also, a feature of the present invention is that the anti-sway horizontal rail 2 is pushed away by the elastic deformation of the retaining piece 9 of the horizontal rail insertion side opening 6 so that the horizontal rail is fixed at a constant distance in the longitudinal direction. After being inserted into all the metal prismatic column main bodies 1 erected in the vertical direction, the anti-sway horizontal rail 2 is turned sideways (that is, the opening 2d of the channel material is directed upward as shown in FIG. 1). By fitting the anti-sway horizontal bar 2 into the fitting grooves 4 and 5 of the openings 6 and 7, the one-sided retaining piece 9 is resiliently restored by the bent open portion 8 as shown in FIG.
Alternatively, as shown by the solid line in FIG. 3, the anti-sway horizontal rail 2 automatically returns to the upper surface 2 a (FIG. 1) of the anti-sway horizontal rail 2. There is no escape from 4 and 5 upwards.

Therefore, the horizontal rails 2 for preventing the steady movement are provided with the fitting grooves 4 and 5.
It is not necessary to bend the stopper piece 9 to its original state at the bent open portion 8 after it is fitted to the opening, so that the on-site construction can be further simplified from this aspect. .

Also, as a feature of the embodiment of the present invention, the anti-sway horizontal rail 2 is oriented sideways (that is, as shown in FIG. 1 or FIG.
d is directed upward or downward), and when the anti-sway horizontal rail 2 is fitted into the fitting grooves 4, 5 of both openings 6, 7, the horizontal rail insertion side opening 6 is fitted. On the groove 4 side, as shown in FIG. 3 (c) or (d), the web 2e or the side piece 2a of the horizontal rail 2 collides with the retaining piece 9 and the retaining The piece 9 is elastically deformed,
Further, as the opening 2d displaces the horizontal rail 2 upward or downward, the side piece side surface 2a on one side of the horizontal rail 2 presses the elastic projection 12a on the retaining piece 9 side, and the elastic projection 12a As shown by the dashed line in the drawing, the elastic member is elastically deformed, and at the same time, the side piece 2b on one side of the cross rail 2 enters the cut 13a on the retaining piece 9 side, and from that state to FIG. 1 or FIG. As shown in FIG. 3D, when the opening 2b of the horizontal rail 2 is completely displaced downward, as shown in FIG. 3D, the horizontal rail 2 is displaced completely downward. The side piece 2b on the other side enters the cut 13a or 13b in a thorough manner, the side face 2a of the side piece presses against the elastic projection 12a or 12b, and the side piece 2b, 2b The upper end surface 2c, 2c or the web 2e is the locking edge 1 a, it is engaged in 14b.

By the above-described operation, the horizontal rail 2 has its web 2e or both side upper end surfaces 2c, 2c abutting against the bottom surface 4a of the fitting groove 4, and both side single side surfaces 2a, 2a of the horizontal rail 2
Are resiliently pressed by the elastic projections 12a, 12b, and the upper ends 2c, 2c or the webs 2e on both sides of the horizontal rail 2 are locked to the locking edges 14a, 14b, so that the horizontal rail 2 is fitted into the fitting groove 4. It will be firmly supported. Of course retaining piece 9
Since the locking edge 14a on the side is continuous with the lower edge 9a of the retaining piece 9, it is natural that the lower edge 9a also serves as the locking edge 14a in many cases.

At this time, as described above, the elastic projection 12a on the side where the retaining piece 9 is projected is connected to the other elastic projection 12b.
The protrusion 13a is slightly larger than the other cut 13a.
The engagement edge 14a on the side where the retaining piece 9 protrudes is formed slightly larger in engagement area than the other engagement edge 14b. Accordingly, when the horizontal rail 2 is fitted into the fitting groove 4, the elastic projection 12a having a large protrusion amount has a large elastic deformation amount, and the horizontal rail 2 is inserted into the cut 13a having a large cut amount. Intrusion is facilitated, and locking to the locking end surface 14a having a large locking area is facilitated.

After the above operation is completed, as shown in FIG. 4, the board material 20 for the upper wall is fixed to the inside and outside surfaces of the metal square column 1 by screwing.

[0030]

According to the first aspect of the present invention, when the horizontal rail for steadying is inserted into the opening of the metal prismatic column main body standing upright in the longitudinal direction of the horizontal rail, the horizontal rail for steadying is inserted. Since there is no need to open the opening by bending each of the retaining pieces for restricting the removal of the door, the on-site construction can be performed simply.

Further, after the anti-sway horizontal rail is inserted into the opening of the metal prismatic column main body, the retaining pieces for controlling the removal of the anti-sway horizontal rail are bent one by one to the original state. Since there is no need to close the opening, on-site construction can be further simplified from this aspect.

According to the second aspect of the present invention, the anti-sway horizontal rail is provided at the opening of the opening of the metallic prismatic column main body with a retaining piece for restricting removal of the anti-sway horizontal rail. At the time of pushing and inserting by elastic deformation, the retaining piece can be pushed away by light insertion work of the anti-sway horizontal bar, so the work of inserting the anti-sway horizontal bar into the metal square column body further from this surface Can be easily performed, and work efficiency can be improved.

According to the third aspect of the present invention, after the anti-sway crosspiece is inserted into the opening of the metal prismatic column main body,
The anti-sway horizontal rail is fitted into the fitting groove, which is a narrow portion of the opening, to restrict the removal thereof. According to the present invention, the anti-sway horizontal rail is connected to the opening. The work of fitting into the fitting groove after inserting it into the fitting groove can be performed smoothly, and by fitting into the fitting groove, the removal edge is restricted by the wide edge of the retaining piece. As a result, it is possible to reliably prevent the horizontal rail for rest from coming off from the fitting groove.

According to the fourth aspect of the present invention, the bottom surface of the horizontal rail is abutted against the bottom surface of the fitting groove, the side surfaces of both sides of the horizontal rail are resiliently pressed by the elastic projections, and both sides of the horizontal rail are provided. The horizontal rail is firmly supported by the fitting groove by locking the upper end surface of the one part to the locking edge.

According to the fifth aspect of the present invention, the amount of protrusion of the elastic projection on the side where the retaining piece projects is slightly larger than that of the other elastic projection. The notch on the side to be provided has a slightly larger amount of cut than the other notch, and similarly, the locking edge on the side where the retaining piece protrudes is larger than the other locking edge. When the horizontal rail is fitted into the fitting groove by being formed slightly larger, the elastic projection having a large projection amount has a large amount of elastic deformation, and the horizontal rail has a large depth of cut. , And it is easy to be locked to the locking end surface having a large locking area.
