In this example, as shown in FIG. 6, a pair of left and right flanges 25 protrude on both side surfaces on the long side of the support column 1 so as to face each other, and the tips of the left and right flanges 25 are further bent inward. A lip piece 12 is formed, and a portion surrounded by the flange 25 and the lip piece 12 is a lip groove 7. The outer corner 12a of the lip piece 12 is rounded so as to prevent the clothes from being caught. In this example, a post cover 11 having a U-shaped cross section, which will be described later, is attached to a portion of the lip groove 7 where the cross rail 2 is not provided.

  As shown in FIG. 10, the column base 17 has a column insertion shaft 19 integrally projecting upward from a base portion 18 fixed to the floor 16, and the lower end 1 d of the column 1 is connected to the column insertion shaft 19. It is fitted and fixed. As shown in FIG. 6, the support insertion shaft 19 has a substantially rectangular shape slightly smaller than the support 1.

  The support pedestal 17 is made of, for example, die-casting or the like, and a base portion 19 a of a square cylindrical support insertion shaft 19 is bent outwardly and is integrally formed with the base portion 18. The base portion 18 is fixed to the floor surface 16 by pedestal mounting bolts 26. In this example, the outer surface of the corner portion 21 formed by the base portion 19a of the support column insertion shaft 19 and the base portion 18 is an outer round surface R having a large vertical cross-sectional shape, and the base portion 18 and the support column. The base portion 19 a of the insertion shaft 19 is integrally formed so as to be continuous via the outer rounded surface R. Thereby, the strength improvement of the corner part 21 is achieved.

  From the outer rounded surface R, a positioning protrusion 20 for projecting and positioning the lower end portion 1d of the support column 1 is projected. As shown in FIG. 5A, the positioning protrusion 20 of the present example has a plurality (six in this example) of ribs 20a that project radially outward from the outer rounded surface R around the column insertion shaft 19. , 20b. The upper ends of the ribs 20a and 20b are the same or higher than the upper end of the outer round surface R. The ribs 20a and 20b in this example are composed of two short ribs 20a provided on the short side of the column insertion shaft 19 and one long rib 20b provided on the long side. As shown in FIG. 6, the width dimension d1 of the short rib 20a is set to a length that allows the lower end 1d of the column 1 to be placed, and the width d2 of the long rib 20b is the lower end 1d of the column 1 and the column cover 11. The lower end portion of the base cover 22 and the lower end of the inner edge portion 22a of the base cover 22 can be placed on each other. That is, the two short ribs 20a are provided at two locations on the long side of the lower end portion 1d of the support column 1, two locations on the lower end portion of the support column cover 11 described later, and two locations on the lower end of the inner edge portion 22a of the base cover 22. Each of the long ribs 20b supports the central portion on the short side of the lower end 1d of the support column 1.

  Further, as shown in FIG. 10, the column insertion shaft 19 is provided with a screw hole 28 above the upper end of the positioning projection 20, and the lower end 1 d of the column 1 is placed on the positioning projection 20. The screw hole 28 and the screw hole 29 provided in the column 1 are aligned, and the column 1 and the column insertion shaft 19 can be fixed with screws.

  Next, the base cover 22 will be described. The base portion 18 of the support base 17 is concealed by a base cover 22 having a square outline in plan view. The base cover 22 covers the base portion 18 from above. In this example, as shown in FIGS. 8 and 9, the base cover 22 is formed in a half-crack shape that can be abutted from both sides of the column 1. The half-cracked base cover 22 has the same shape, the inner edge 22 a is abutted against the outer surface of the lower end 1 d of the column 1 and the outer peripheral surface of the lower end of the column cover 11, and the outer edge 22 b is against the floor 16. It is supposed to be placed.

  Here, as shown in FIG. 9A, the inner edge portion 22 a of the base cover 22 includes a U-shaped edge 31 that abuts across the both end surfaces of the column 1 from the outer surface of the column cover 11, and a U-shaped edge. The convex edge 32 (FIG. 8, FIG. 9 (a), (b), (c)) continuing to the one end side of 31 and the concave edge 33 (FIG. 8, FIG. 9) continuing to the other end side of the U-shaped edge 31 (A)). Then, the U-shaped edges 31 are abutted from the outer surface of the column cover 11 along both end surfaces of the column 1 with the pair of half-cracked base covers 22 turned in opposite directions and fitted from both sides of the column 1. In addition, the convex edge 32 and the concave edge 33 that are abutted with each other are fitted up and down (in the state of FIG. 4A). Further, the inner edge portion 22a of the base cover 22 is bent downward in an L-shaped longitudinal section, and a lower end of a part of the inner edge portion 22a is placed on the upper surface of the base portion 18 and other inner edge portions 22a A cutout portion 34 (FIG. 8) is formed in a portion facing the positioning projection 20, and the lower end of the cutout portion 34 is placed on the positioning projection 20 as shown in FIG. Yes.

  Furthermore, as shown in FIGS. 9B to 9H, a plurality of (three in this example) positioning pins 35 project downward from the lower surfaces of the pair of half-cracked base covers 22, On the other hand, a pin insertion hole 36 is formed on the upper surface of the base portion 18 as shown in FIG. 5A, and the positioning pin 35 is fitted in the state where the base cover 22 is fitted from both sides of the column 1 as described above. Each of the base covers 22 is thus positioned and fixed with respect to the base portion 18. Long holes 27 (FIG. 5) through which the base mounting bolts 26 are inserted are formed at the four corners of the base portion 18. Further, in this example, as shown in FIG. 10, since the head portion 26 a of the base mounting bolt 26 protrudes from the upper surface of the base portion 18, the base cover 22 is lifted upward from the upper surface of the base portion 18. Thus, the base cover 22 and the head portion 26a of the base mounting bolt 26 are prevented from interfering with each other. Further, the length of the positioning pin 35 is set so that the tip of the positioning pin 35 is inserted into the pin insertion hole 36 in a state where the base cover 22 is lifted upward from the upper surface of the base portion 18 in this way. ing.

  Next, the horizontal rail mounting structure will be described. As shown in FIG. 1 or FIG. 12, the end portion of the horizontal beam 2 made of a square bar is inserted into a part of the lip groove 7 provided on the side surface 1 b of the column 1. A tapping hole 4b is formed in the end surface 2a of the horizontal beam 2, and the tapping hole 4b is tapped from a screw insertion hole 3d provided on one end 3a side of the horizontal beam connecting plate 3 protruding in the direction N perpendicular to the axis of the horizontal beam 2. By screwing the screws 4 a, the one end 3 a side of the horizontal beam connecting plate 3 is fixed to the end surface 2 a of the horizontal beam 2. The crosspiece connecting plate 3 is made of a rigid plate and is sized to be inserted inside the lip groove 7 of the column 1. The vertical width of the horizontal beam connecting plate 3 is formed to be larger than the outer diameter of the end surface 2a of the horizontal beam 2, and is located on the other end 3b side of the horizontal beam connecting plate 3 and away from the end surface 2a of the horizontal beam 2. A screw hole 3c is formed at the position. On the other hand, the support column 1 is formed with a through hole 1a that penetrates in the direction M perpendicular to the support column 1 and opens on both side surfaces 1b of the support column 1 respectively.

  In this example, the tapping screw 4a is screwed into the tapping hole 4b to fix the horizontal beam connecting plate 3 to the end surface 2a of the horizontal beam 2, and the head 4c of the tapping screw 4a is connected to the horizontal beam connecting plate 3. It is supposed to protrude behind. On the other hand, a small hole 1c is formed in the side surface 1b of the support column 1 at a position spaced a predetermined distance S ′ from the lateral hole 1a. As shown in FIG. 11, the predetermined distance S ′ is substantially the same distance as the distance S between the screw insertion hole 3 d and the screw hole 3 c of the crosspiece connecting plate 3. Thereby, when the horizontal beam connecting plate 3 is applied to the side surface 1b of the column 1, the head 4c of the tapping screw 4a is fitted into the small hole 1c, so that the screw hole 3c of the horizontal beam connecting plate 3 is inserted into the column 1. The through hole 1a can be positioned. Thereafter, the through screw 5 is passed through the horizontal through hole 1a of the column 1 from the screw hole 3c of one horizontal beam connecting plate 3 and protrudes from the screw hole 3c of the other horizontal beam connecting plate 3 to be fastened. The crosspiece 2 can be connected to the column 1.

  A countersunk screw may be used as the tapping screw 4a so that the head 4c of the tapping screw 4a does not protrude behind the horizontal beam connecting plate 3. In this case, the side surface 1b of the column 1 is positioned for positioning. It is not necessary to provide the small hole 1c, and the hole processing can be omitted.

  Furthermore, in this example, a rotation prevention piece 10 (FIGS. 10 to 12) that abuts against a side surface 2b orthogonal to the end surface 2a of the horizontal beam 2 protrudes from one end portion 3a of the horizontal beam connecting plate 3. The rotation of the horizontal beam connecting plate 3 with respect to the horizontal beam 2 is prevented. In addition, there are two types of the cross rail connecting plate 3, that is, a type in which the rotation preventing piece 10 is provided and a type 3 ′ (FIG. 12) in which the anti-rotation piece 10 is not provided.

  Next, the column cover 11 that covers the lip groove 7 will be described. As described above, the end portion of the cross rail 2 is bridged over a part of the lip groove 7 of the column 1, and the remaining part of the lip groove 7 is covered with the column cover 11. The column cover 11 conceals the horizontal beam connecting plate 3 for connecting the horizontal beam 2 to the column 1, the through screw 5 and the nut 6 to improve the appearance. As shown in FIG. 6, the column cover 11 of this example is formed in a substantially U shape in plan view, and closes the opening between the lip pieces 12 and 12 and is arranged flush with the front surface of the lip piece 12. A front panel portion 13 and a pair of left and right engaging portions 14 bent rearwardly from both left and right ends of the front panel portion 13 are provided. The pair of left and right engaging portions 14 respectively contact a bottom surface of the lip groove 7 (side surface 1b of the support column 1) and a first contact portion 14a for stopping the front and back (left and right direction in FIG. 6) movement of the support column cover 11; A second abutting portion 14b is provided for stopping the movement of the column cover 11 in the front-rear and right-and-left directions (vertical direction in FIG. 6) when it hits the rear corner of the lip piece 12.

  By the way, when the horizontal beam 2 is inserted into a part of the lip groove 7 and connected, in order to move and position the horizontal beam 2, it is necessary to secure a predetermined gap with the lip piece 12. Therefore, a predetermined gap (an end surface line L2 of the horizontal beam 2 in FIG. 1C) is generated on the end surface of the horizontal beam 2. On the other hand, when the end surface of the front panel portion 13 of the column cover 11 is brought into contact with the lip piece 12 without a gap, the end surface line L2 of the horizontal rail 2 is interrupted at the front panel portion 13 and It feels strange and doesn't look good. Therefore, in this example, the support cover 11 is stopped by the first contact part 14a and the second contact part 14b provided in the engaging part 14 so that the front / rear and left / right movements of the support cover 11 with respect to the lip groove 7 are stopped. Therefore, the end surface of the front panel portion 13 of the column cover 11 can be arranged away from the lip piece 12, and therefore, the end surface line L1 (see FIG. c), FIG. 13 (b)) can be formed, and this end face line L1 is inserted into a part of the lip groove 7 and connected to the end face line L2 (FIG. 1 (c), FIG. a)) can be formed substantially in a straight line, and the appearance is improved. Further, the lower end portion of the support cover 11 is positioned in the vertical direction by being placed on the positioning protrusion 20 of the support base 17 as shown in FIG. As shown in FIG. 6, the support cover 11 has a flat front panel 13 as a whole, and a shielding plate 24, which will be described later, in the center of the front panel 13 as shown in FIG. There is a type provided with a groove into which the end of the groove is inserted.

  Next, two methods for constructing a loft fence will be described as examples. In the first method, the support base 17 is fixed to the floor 16, the support 1 is externally fitted to the support insertion shaft 19 of the support base 17 and fixed with screws, and then the horizontal rail 2 is installed, the support cover 11 and The headboard 23 is attached, and the loft fence shown in FIG. 2 or FIG. 3 is constructed. First, a plurality of support pedestals 17 are fixed to the floor surface 16 at a predetermined interval, and the lower ends 1d of the plurality of support posts 1 are fitted into the support insertion shafts 19 of the support support pedestals 17, respectively. At this time, the lower end 1d of the column 1 is placed and positioned on the positioning projection 20 protruding outward from the column insertion shaft 19, and the column 1 and the column insertion shaft 19 are fixed with screws. Thereafter, a cross rail 2 is installed between the columns 1. At this time, when the horizontal beam 2 is arranged on both sides of the column 1 as shown in FIG. 1, two horizontal beam connection plates 3 are respectively attached to the end surfaces 2a of the two horizontal beams 2 as shown in FIG. Secure with screws. When the horizontal beam 2 is arranged only on one side of the column 1 as shown in FIG. 12, the end surface 2a of the horizontal beam 2 is screwed to only one of the two horizontal beam connection plates 3. Then, with one horizontal beam connecting plate 3 applied to one side 1b of the column 1 and the other horizontal beam connecting plate 3 applied to the other side 1b of the column 1, the through screw 5 is connected to one horizontal beam. From the screw hole 3 c of the plate for plate 3, it passes through the through hole 1 a of the support column 1, passes through the screw hole 3 c of the other horizontal beam connecting plate 3, and is fastened by the nut 6. Thereby, as shown in FIG. 1, the horizontal beam 2 can be connected to both sides of the column 1 or the horizontal beam 2 can be connected to only one side of the column 1 as shown in FIG. Thereafter, the headboard 23 is spanned between the tops 1 e of the support columns 1, and the headboard 23 is fixed with the tapping screw 8 as shown in FIG. 14. At this time, tapping holes 9 are provided at the four corners of the top portion 1 e of the support column 1 so that the bottom plate portion 23 a of the headboard 23 can be fixed by the tapping screw 8.

  In the second method for constructing the loft fence, first, a frame body composed of the support column 1 and the cross rail 2 is assembled in advance. First, a plurality of columns 1 are placed on the floor 16 so as to be aligned, and the horizontal beam connecting plate 3 fixed to the horizontal beam 2 is fixed to the column 1 in a state where the horizontal beam 2 is arranged between the columns 1. The column 1 and the horizontal beam 2 are connected in the same manner as described above. As shown in FIG. 1, the horizontal beam 2 is connected to both sides of the column 1, or as shown in FIG. 12, only one side of the column 1 is connected. The crosspiece 2 is connected to Thereafter, the assembled frame is raised, and the lower ends 1d of the plurality of columns 1 constituting the frame are externally fitted to the column insertion shafts 19 of the column bases 17 fixed to the floor 16 and fixed with screws. The column cover 11 and the headboard 23 may be attached at the same time as the assembly of the frame or after the frame is fixed to the column base 17.

  In either of the first and second construction methods, the shielding plate 24 (FIG. 1B) may be fitted into the lower half of the loft fence for the purpose of blindfolding, soundproofing, or the like. The shield plate 24 is attached by forming a groove on the inner peripheral surface of the frame composed of the left and right support columns 1 and the upper and lower horizontal rails 2 and making the outer peripheral edge of the shield plate 24 a groove. Fit it in.

  According to the above configuration, when the horizontal beam 2 is installed between the columns 1, the horizontal beam connection plates 3 are respectively attached to the lip grooves 7 on both sides of the column 1, and the horizontal beam connection plate 3 and the column 1 are connected with the through screws 5. The horizontal rails 2 can be attached to both sides of the support column 1 at a time, and it takes less time and effort to assemble. The work can be done quickly, and labor saving and cost reduction can be achieved. In addition, by making the horizontal crosspiece connecting plates 3 on both sides the same shape, the horizontal crosspieces 2 can be arranged on a horizontal straight line with the column 1 interposed therebetween, and the height of the horizontal crosspieces 2 is aligned with a small number of parts and at low cost. And the appearance of the loft fence can be improved.

  In this example, the positioning and fixing means 4 includes a screw insertion hole 3d provided on the one end 3a side of the horizontal beam connecting plate 3, and a tapping formed in the end surface 2a of the horizontal beam 2 and inserted from the screw insertion hole 3d. Since the tapping hole 4b is engaged with the screw 4a, the positioning of the horizontal beam connecting plate 3 with respect to the horizontal beam 2 can be performed easily and at low cost.

  Further, the head 4c of the tapping screw 4a is placed behind the horizontal beam connecting plate 3 in a state where the horizontal beam connecting plate 3 is positioned and fixed to the end surface 2a of the horizontal beam 2 by screwing the tapping screw 4a into the tapping hole 4b. A small hole 1c into which the head 4c of the tapping screw 4a can be inserted is formed at a position in the vicinity of the portion of the column 1 to which the horizontal rail 2 is attached, and the side surface 1b of the column 1 is fixed before the fixing with the through screw 5 Since the head 4c of the tapping screw 4a is fitted into the small hole 1c when the horizontal beam connecting plate 3 is applied, the horizontal beam connecting plate 3 can be positioned at a proper position on the side surface 1b of the column 1. Therefore, it is not necessary to align the screw hole 3c of the horizontal beam connecting plate 3 and the horizontal through hole 1a of the support column 1 by sliding the horizontal beam 2, and the screw fixing operation of the horizontal beam 2 by the through screw 5 is accelerated. There is a point.

  Further, since the anti-rotation piece 10 that abuts against the side surface 2b orthogonal to the end surface 2a of the horizontal beam 2 is integrally projected from one end 3a of the horizontal beam connecting plate 3, the horizontal beam 2 Since the rotation of the horizontal beam connecting plate 3 with respect to the tapping screw 4a and the tapping hole 4b (FIG. 10 (a)) is facilitated, the horizontal beam connecting plate 3 and the horizontal beam using the tapping screw 4a are easily positioned. There is also an advantage that the connecting work with 2 is quick and the workability is improved.

  In addition, although the case where the support | pillar 1 and the support | pillar insertion axis | shaft 19 were screw-fixed was illustrated in the said embodiment, of course, not only screw fixation but fixation by a rivet etc. may be sufficient.

  The fence of the present invention is not limited to a loft fence in a house, but can be used as a landing for a house or a fence for the second floor. In addition, it can be widely used for outside fences installed outdoors.
