The subassembly 14 shown in FIG. 5 is composed of a vertical rail 26, a small rail 28, and an upper and lower frame 30, and is formed in a rectangular shape. The pair of vertical rails 26 are connected to both ends of the pair of upper and lower frames 30 and both ends of the small rail 28 to form the subassembly 14. The sub-assembly 14 is in a state before becoming the main body portion 12, and is in a state in which the upper and lower rails 24 are not assembled.

FIG. 5 shows a state in which the small rail 28 and the upper and lower frames 30 are screwed laterally to the connecting plate portion 26b of the vertical rail 26. A semi-cylindrical screw portion 28a is formed inside the small crosspiece 28. The small rail 28 is inserted into a pair of facing plate portions 26a, the screwed portion 28a of the small rail 28 is aligned with the first mounting hole 26e, and the small rail 28 is screwed with the screw 36 to make the small rail 28 into the vertical rail 26. It is screwed. The plurality of small rails 28 are provided between the pair of upper and lower frames 30, and are screwed to the pair of vertical rails 26 in the lateral direction.

The ends of the upper and lower frames 30 are placed on the first contact portion 26c, and by contacting the second contact portion 26d, the screw portion 30b and the second mounting hole 26f are aligned and screwed with the screw 36. By doing so, the upper and lower frames 30 are screwed to the vertical rails 26. The first contact portion 26c abuts vertically on the ends of the upper and lower frames 30, and the second abutment portion 26d abuts laterally on the ends of the upper and lower frames 30. As a result, the ends of the upper and lower frames 30 can be formed with a simple structure, and even if the upper and lower frames 30 are cut and shortened, they can be assembled to the vertical rail 26. That is, the length of the upper and lower frames 30 can be easily adjusted, and the upper and lower frames 30 can be cut and adjusted at the assembly site of the fence 10.

By providing the small rail 28 and the upper and lower frames 30 in the horizontal direction with respect to the vertical rail 26, the small rail 28 and the upper and lower frames 30 can be assembled in any order, facilitating the assembly work. it can.

By directly screwing the vertical rail 26 to the upper and lower frames 30, it is possible to suppress rattling between the vertical rail 26 and the upper and lower frames 30. Since the vertical rail 26 is directly fixed to the small rail 28, it is integrated with the small rail 28, and it is very effective to suppress the rattling of the vertical rail 26 when the small rail 28 is shaken by the wind or the like. Is the target.

Of the ridge portion 26g and the receiving portion 26h of the pair of vertical rails 26, the ridge portion 26g of one vertical rail 26 is inserted into the receiving portion 26h of the other vertical rail 26, and the ridge portion of the other vertical rail 26 is inserted. A pair of vertical rails 26 are connected by inserting 26 g into the receiving portion 26h of one vertical rail 26. Thereby, when connecting the two subassemblies 14, it is possible to eliminate the need to provide another center rail at the connecting portion. Further, since a plurality of subassemblies 14 can be connected, it is easy to set the lateral length of the main body portion 12. In addition, vertical bars 26 having the same shape can be connected to each other.

The two sub-assemblies 14 are integrated into the main body portion 12 by sliding-fitting the upper and lower frames 30 to the upper and lower rails 24. The slide of the upper and lower frames 30 is guided by the slide guide 40 of the upper and lower rails 24.

FIG. 6 is a cross-sectional view of the line segment BB of the fence 10 shown in FIG. The upper rail 24a and the lower rail 24b are formed in a substantially U-shaped cross section. A pair of slide guides 40 are formed on the inner surfaces of the upper rail 24a and the lower rail 24b, respectively. The pair of slide guides 40 face each other and accept the overhanging portion 30c which is the side edge of the upper and lower frames 30 to slidably grip the upper and lower frames 30. The upper and lower rails 24 are slidably connected to the upper and lower frames 30 and cover the upper and lower frames 30. The overhanging portion 30c functions as a slide portion that slides and connects to the slide guide 40.

The upper and lower rails 24 and the upper and lower frames 30 are connected by sliding the pair of slide guides 40 and the side edges of the upper and lower frames 30, and the main body portion 12 is assembled. The main body 12 may be provided with caps that cover both ends of the upper and lower rails 24, and may be provided with a cover member that covers the outer surface of the vertical rails 26. The slides of the upper and lower rails 24 and the upper and lower frames 30 may be restricted by caps covering both ends of the upper and lower rails 24. A cover member that covers the outer surface of the vertical rail 26 prevents the screws 36 from being exposed.

The upper and lower rails 24 cover the joint portion of the upper and lower frames 30 and the vertical rails 26. The joint portion between the upper and lower frames 30 and the vertical rail 26 is an end portion of the upper and lower frame 30 and a first contact portion 26c and a second contact portion 26d of the vertical rail 26. As a result, it is possible to prevent the joint portion of the upper and lower frames 30 and the vertical crosspiece 26 from being exposed.

The main body 12 is connected to the support column 20 by the bracket 22. The upper bracket 22a is caught on the lower surface of the upper rail 24a and regulates the movement of the upper rail 24a in the downward direction and the movement of the upper rail 24a in the direction away from the support column 20. The lower bracket 22b abuts on the lower surface of the lower rail 24b to regulate the movement of the lower rail 24b in the downward direction. The lower bracket 22b is screwed to the support column 20. In this way, the main body 12 is supported by the support column 20 and the fence 10 is assembled. The operator can easily install the fence 10 by assembling the main body 12 in advance, carrying it to the work site, and connecting it to the support column 20.

FIG. 7 is a diagram for explaining the assembly of the main body portion 12, and is an exploded view of the main body portion 12.
(1) First Step The small rail 28 and the upper and lower frames 30 are screwed to the vertical rail 26 to form the subassembly 14. In the first step, both the small rail 28 and the upper and lower frames 30 can be screwed in the lateral direction, so that the screwing order can be freely set.
(2) Second Step The upper and lower frames 30 of the subassembly 14 are slidably fitted to the upper and lower rails 24 to form the main body 12. When the subassembly 14 is slid, the vertical crosspieces 26 of the adjacent subassemblies 14 are connected by the ridge portion 26g and the receiving portion 26h.
In this way, the main body 12 is assembled and assembled to the support column 20 to form the fence 10.

It should be noted that the examples are merely examples, and it is understood by those skilled in the art that various modifications are possible for the combination of each component, and that such modifications are also within the scope of the present disclosure.
