The column cap includes a cap body and a support, and the cap body covers the column upper end. And a skirt part suspended from the periphery of the cover part, and the support body is suspended from the inner surface of the cover part, and is fixed to the inner surface of the cover part and bent parts formed on both side ends thereof The bent portion is elastically deformable inward from the start end to the tip end, and covers the outer surface of the bent portion between the outer surface of the bent portion and the inner surface of the skirt portion from the start end. The upper end of the support column is inserted between the virtual surface extending in the inner surface direction of the part and the inner surface of the skirt part, and the start end of the bent part is positioned below the tip of the hem part. It is a feature.

  In the support cap according to the present invention, the support is formed of a vertical plate portion formed in a direction crossing the inner surface of the cover portion, and opposite directions along the inner circumferential direction of the cover portion from both ends of the vertical plate portion. It is characterized by having a horizontal cross section Z-shaped by a bent portion bent in the direction.

  The support cap according to the present invention is characterized in that a through hole is formed in the bent portion.

  Further, the protective fence according to the present invention is characterized in that a beam material is erected between the columns to which the column cap is mounted, and a support member that supports the beam material is mounted on the column side by a through bolt that penetrates the column. It is what.

  Further, the guard fence according to the present invention includes a support member for fixing the support cap to the support post through the through hole formed on the side of the support post to the bent portion through which the support cap is attached to the upper end of the support post.

Next, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
In the drawing, 1 is a support, 2 is a beam material installed between the support 1, 3 is a support member for supporting the beam 2 on the support 1, and 4 is a support cap attached to the upper part of the support. The protective fence P according to the embodiment includes a support column 1, a beam material 2, a support member 3, and a support column cap 4.

  The support column 1 is a steel pipe having a circular cross section, and a plurality of support columns 1 are provided on the ground at appropriate intervals. A beam member 2, which is a steel pipe having a circular cross section, is installed between the columns 1. The mounting bracket as the support member 3 includes a flat plate-like vertical plate portion 31 fixed to the column 1 and a holding portion 32 that holds the beam material 2. The vertical plate portion 31 is in contact with the support column 1 on the back side thereof, and a through bolt B1 penetrating the support column 1 in the lateral direction is inserted, and by tightening a nut screwed into the through bolt B1, The vertical plate portion 31 is fixed to the column side surface 11 of the column 1, whereby the support member 3 is attached to the column 1.

  The holding portion 32 of the support member 3 is formed by a beam by an upper plate portion 322 and a lower plate portion 323 that protrude in a horizontal direction from an upper end and a lower end of a vertical plate-shaped beam mounting portion 321 extending from the vertical plate portion 31. The material 2 is held, two support members 3 are opposed to each other in the front and back, the column side surface 11 and the end of the beam material 2 are sandwiched, and each is fixed by through bolts B1 and B2. .

  The support cap 4 includes a cap body 5 and a support body 6, and the cap body 5 is hung down slightly obliquely below a cover portion 51 formed in a dome shape covering the upper end of the support 1 and the periphery of the cover portion 51. The support body 6 is suspended from the inner surface of the cover portion 51 and is fixed to the inner surface 511 of the cover portion 51, and bent portions formed on both side ends thereof. The bent portion 62 is elastically deformable inward from the start end 621 to the tip end 622, and the outer surface 623 of the bent portion 62 extends from the start end 621 toward the inner surface 511 of the cover portion 51. The through-bolt for attaching the support 1 support member 3 to the through hole 611 in which the upper end of the support 1 is inserted between the virtual surface and the inner surface 521 of the skirt 52 and is drilled in the center of the vertical plate 61. B1 is inserted and prop cap 4 is It has been made so as not to escape from pillar 1 unnecessarily.

Further, the structure of the support cap 4 will be described in detail.
The support 6 is folded in opposite directions along the inner circumferential direction of the cover 51 from both side ends of the vertical plate 61 and the vertical plate 61 formed in a direction crossing the inner surface 511 of the cover. The bent section 62 has a horizontal cross section Z-shaped, and the start end 621 of the bent section 62 is positioned below the tip 522 of the skirt 52, that is, abuts against the inner surface of the column 1. The bent portion 62 is shaped such that a space between the start end 621 and the inner surface 511 of the cover portion 51 is cut out, and is an upper portion of the bent portion 62 with respect to the skirt portion 52 that contacts the outer surface of the support column 1. Are not overlapped in side view. And although the inner surface 511 of the cover part 51 and the upper end edge of the vertical plate part 61 are being fixed by spot welding, since the cover part 51 is formed in the dome shape, the vertical plate part 61 is flat form. If it exists, the upper end edge and the cover part 51 will be in point contact, and it cannot be said that the strength surface is sufficient only by spot welding the part. Therefore, in order to further improve the welding strength, both side ends of the upper portion 612 of the vertical plate portion 61 are bent at substantially right angles, and the corner portions 613 are spot-welded. If the corner portion 613 is spot-welded, the welding area can be increased, and the upper end of the upper bent portion 614 obtained by bending both ends of the upper portion 612 of the vertical plate portion 61 substantially at right angles comes into contact with the inner surface 511 of the cover portion 51. Therefore, when the support cap 4 is inserted into the support 1, the applied force is distributed by increasing the area received by the vertical plate 61 when a force is applied from above the cover 51 with a hammer or the like. can do. In the present embodiment, the bent portion 62 and the upper bent portion 614 are bent in the same direction, but may be bent in opposite directions.

  By doing so, when the support cap 6 is crowned on the upper end of the support 1 and the support 6 is inserted into the support 1 and the support cap 4 is inserted further deeply, the bent portion 62 of the support 6 is formed. Even if the elastic force acts, the bent portion 62 is fixed to the inner surface 511 of the cover portion 51 via the vertical plate portion 61, that is, by cutting the inner surface 511 of the cover portion 51 and the bent portion 62. The displacement of the bent portion 62 prevents the elastic force from directly acting on the inner surface 511 of the cover portion 51 and the upper end of the vertical plate portion 61, that is, the spot welding fixing portion between the cap body 5 and the support body 6, for example, wood Even if the covering portion 51 is hit with a striking tool such as a scissors and the support cap 4 is inserted, that is, the outer surface 623 of the bent portion 62 extends from the starting end 621 toward the inner surface 511 of the covering portion 51 and the skirt portion 52. Insert the upper end of the column 1 between the inner surface 521 However, it is possible to effectively develop the spring elastic force of the bent portion 62 while making it difficult for the spot weld fixing portion between the cap body 5 and the support 6 to come off, so that the column cap 4 can be It can be held firmly.

  The bent portion 62 is formed with a through hole 624. As shown in FIG. 3, the through-hole 624 can be suitably used when the support cap 4 is attached to the guard fence P that does not have a structure for attaching the support cap 4 to the support 1 using the through bolt B <b> 1. That is, in the protective fence P shown in FIG. 3, the panel holding member 7 is welded and fixed to the opposite side surfaces of the adjacent struts 1, and is welded and fixed to the side surface of the vertical lattice 81 arranged at the extreme end of the vertical lattice panel 8. The panel mounting member 82 is placed on the upper end of the panel holding member 7, and is a protective fence P fixed by penetrating the panel holding member 7 and the panel mounting member 82 through the through bolt B3 in the vertical direction. When the column cap 4 is attached to the column 1, a through hole is formed in the column side surface 11 where the through hole 624 formed in the bent portion 62 is located, and a fixing member 9 such as a tapping screw is screwed into the column 1. The support cap 4 can be fixed to the frame. In this way, as long as the through-hole is provided in the support side 11, the support cap 4 can be easily attached with the fixing member 9 such as a tapping screw even if the support 1 is of a type having no through-hole in the support side 11. Attachment and protection fence P can be formed, and even if the protection fence P is of a different form such as a type using the beam member 2 and a type using the vertical lattice panel 8, the support cap 4 can be shared.

  Further, the tip 622 of the bent portion 62 is chamfered to form a curved surface portion 625. By doing so, when the support cap 4 is inserted into the support 1, the curved surface portion 625 is inserted while sliding on the inner surface of the support 1, so that the support cap 4 can be easily attached to the support 1.

  A suspension hole 626 is formed in the upper portion of the through hole 624 of the bent portion 62. The suspension hole 626 is used to suspend the support cap 4 by inserting a suspension tool tip such as a hook into the suspension hole 626 when the support cap 4 is plated or painted, for example. In addition, by forming the suspension hole 626 at a position on the upper side of the support cap 4 shifted from the center of gravity of the support cap 4, when the support cap 4 is suspended, the inner surface 511 of the dome-shaped cover portion may face upward. Therefore, no plating solution or paint is accumulated on the inner surface 511 of the cover portion.

  It should be noted that the start end 621 of the bent portion of the column cap 4 of the above-described form is positioned below the tip end 522 of the skirt portion, and the bent portion 62 is viewed from the side with respect to the skirt portion 52 that contacts the outer surface of the column 1. However, the start end 621 of the bent portion 62 is positioned above the tip 522 of the skirt portion 52, and the upper portion of the bent portion 62 overlaps the skirt portion 52 in a side view. You may do it.

  In this way, if the start end 621 of the bent portion 62 is started from a position where it overlaps the skirt portion 52, the column 1 can be compared with a case where the start end 621 of the bent portion 62 starts from a position not overlapping the skirt portion 52. When the upper end of the column is inserted, it is strongly restricted by the skirt portion 52 and the bent portion 62, and a strong force is required by the insertion of the column 1; The rattling of the cap 4 can be suppressed extremely effectively.

  The column 1 is preferably made of metal in consideration of supporting the beam member 2, and generally, a long body made of a pipe or a shape member made of aluminum, stainless steel, steel, or the like is cut into an appropriate length. Those obtained by plating or painting can be preferably used.

  Considering the necessary strength as the protective fence P, the beam member 2 is preferably made of metal like the support column 1 and generally has a long body made of pipes or shapes such as aluminum, stainless steel and steel. What was cut | disconnected appropriately | suitably to length, what plated and painted them, etc. can be used suitably. If the cross-sectional shape of the beam member 2 is circular, the beam attachment portion 321, the upper plate portion 322, and the lower plate portion 323 of the holding portion 32 of the support member 3 are formed in a semicircular shape. If the cross-sectional shape is a square, the beam mounting portion 321, the upper plate portion 322, and the lower plate portion 323 are formed in a half square shape, and the beam mounting portion 321 and the upper plate are aligned with the outer shape of the beam material 2. The part 322 and the lower plate part 323 may be formed.
