[0002] South Korea’s suicide rate is 25 per 100,000 people, averaging 44 per day, and ranks first among OECD (Organization for Economic Co-operation and Development) countries.

[0003] At the national level, measures have been taken to curb the occurrence of suicides, such as installing screen doors at subway stations and erecting fences on bridges. However, a significant number of people end their lives by climbing over fences installed on bridges, and countermeasures have been required.

[0004] Fences installed on bridges are significantly more expensive than those on general roads, and the use of heavy equipment is restricted to ensure bridge safety. Furthermore, since vehicle traffic is obstructed in some form during the construction period, there is a very high risk of causing traffic congestion.

[0005] Accordingly, the applicant proposes a suicide prevention fence equipped with anti-theft bolts that reduces costs and minimizes the occurrence of suicides by extending the existing fence instead of removing and reinstalling the existing fence installed on the bridge. Prior art literature

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0024] FIG. 1 illustrates the connection relationship of a suicide prevention fence (hereinafter referred to as "fence") equipped with an anti-theft bolt according to one embodiment of the present invention, and FIG. 2 illustrates a detailed connection diagram of a lower support of a fence already installed on a bridge and a fence according to the present embodiment.

[0025] Referring to FIG. 1 and FIG. 2, the fence (100) according to the embodiment has a shape that extends from a lower support (10) already installed on the bridge.

[0026] The extension support (110) has a plurality of perforations (101) formed in its body to support a side bar (not shown). The side bar is mounted between the extension supports (110) to control the movement of people and typically has a rod shape. The shape of the perforations (101) can be circular, triangular, square, or polygonal depending on the cross-sectional shape of the side bar. Since the shape of the perforations does not correspond to the main essence of the present invention, it will be omitted below.

[0027] At least one of the side bars mounted on the perforation (101) may be provided with an anti-grip outer layer (102). In FIG. 1, the anti-grip outer layer (102) is illustrated as being formed on a side bar mounted on the end of an extension support (110), but the anti-grip outer layer (102) may be formed on all side bars mounted between extension supports (110).

[0028] The anti-grip outer shell (102) can be formed from materials such as urethane, EVA, and synthetic resin, and can be attached to the surface facing the side bar to increase the diameter (or width) of the side bar. When the diameter of the side bar is increased, it can prevent a person from grabbing it with their hand and climbing over the fence (100).

[0029] If the anti-grip outer shell (102) is formed using urethane and EVA, it can be attached to the side bar to form the anti-grip outer shell. If the anti-grip outer shell (102) is made of rubber or synthetic resin, the anti-grip outer shell (102) can be molded onto the side bar to increase the diameter of the side bar.

[0030] The fence according to the embodiment is composed of an extension post (110) and a multi-stage grid (120) as unit units, and the unit units can be installed on the bridge by arranging a plurality of arrays on the bridge.

[0031] As illustrated in FIG. 2, the fence (100) is connected to the extension post (110) through a multi-stage grid (120). If the outer diameter (or width) of the extension post (110) is larger or smaller than that of the lower post (10), the extension post (110) and the lower post (10) cannot be connected as is. The multi-stage grid (120) fills the gap caused by the difference in diameter (or width, hereinafter omitted) between the extension post (110) and the lower post (10), thereby allowing the lower post (10) and the extension post (110) to be connected.

[0032] A multi-stage grid (120) is provided between the lower support (10) and the extension support (110), and grids having different widths (or diameters) are stacked to form a grid.

[0033] The multi-stage grid (120) can be configured so that each grid is extended or overlapped, and one or more grids can be inserted in an overlapping manner to fit the gap between the lower support (10) and the extension support (110). The overlapping structure of the multi-stage grid will be explained with reference to FIG. 3.

[0034] Figure 3 shows a plan view of a multi-level grid.

[0035] Referring to FIG. 3, the multi-stage grid (120) has a stacked shape of grids (121 to 124). The width of the grid (124) is the largest, and the width decreases monotonically as it goes toward the grid (121). Each grid (121 124) has a gap (d1 to d4) with an adjacent grid. If the length of the gap between the lower support (10) and the extension support (110) corresponds to d1 + d2, the grid (123) and the grid (124) can be fitted and joined between the lower support (10) and the extension support (110) to firmly fix the lower support (10) and the extension support (110). On the other hand, if the gap between the lower support (10) and the extension support (110) is d1 + d2 + d3 in length, the remaining grids (122, 123, 124), excluding the grid (121), can be fitted into the gap between the lower support (10) and the extension support (110) to fill and secure the gap between the lower support (10) and the extension support (110). In this way, the multi-stage grid (120) is configured to selectively adjust the number of grids (121 to 124) to fit into the gap that occurs when the lower support (10) and the extension support (110) are connected.

[0036] The height of each grid (121 to 124) can have the same value. In FIG. 3, grid (124) has a height of h1, grid (123) can be extended from grid (124) to h2, grid (122) can be extended from grid (123) to h3, and grid (121) can be extended to h4. Since each grid (121 to 124) is extended from an adjacent grid, it can move by virtually the same height. For example, the difference between height h4 and height h3 is equal to the difference between height h3 and height h2.

[0037] As described above, the multi-stage grid (120) can have other grids (122 to 124) continuously extended or overlapped around the grid (121).

[0038] Each grid (121 to 124) may have a second perforation hole (121a to 124a) and a first perforation hole (121b to 124b). The second perforation hole (121a to 124a) and the first perforation hole (121b to 124b) may be formed at the same height and position so that when each grid (121 to 124) overlaps, the shape of the perforation becomes the shape of a through hole. In the plan view of FIG. 3, the first perforation hole (125) may have the shape of a single perforation hole when the individual perforation holes (121b to 124b) formed in each grid (121 to 124) are selectively or all overlapped.

[0039] As described above, the multi-stage grid (120) fills the gap between the lower support (10) and the extension support (110), and when a single grid (any one of 121 to 124) fills the gap or when multiple grids (at least two of 121 to 124) overlap, a first perforation hole (125) and a second perforation hole (126) are formed.

[0040] Hereinafter, a method for fixing the multi-stage grid (120) will be described with reference to FIGS. 4 and FIGS. 5.

[0041] First, FIGS. 4 and FIGS. 5 illustrate the structural diagram of the first fixing bolt.

[0042] Referring to FIG. 4, the first fixing bolt (130) is inserted into the multi-stage grid (120) through the first drilling hole (125) and is configured to include a screw cover (131), a bolt body (132), a rotary weight (133), a pin hole (134), a fastening pin (133c), and a fixing nut (136), and a protruding groove (137) may be formed at the end of the screw cover (131).

[0043] The screw cover (131) has a shape determined along the outer circumference of the bolt body (132) and accommodates the bolt body (132).

[0044] When the fixing nut (136) receives an external force in the direction of P1, the bolt body (132) moves in the direction of P1 within the screw cover (131). Thus, the screw cover (131) takes the form of wrapping the bolt body (132), allowing the bolt body (132) to move in the direction of P1 while maintaining its shape.

[0045] The screw cover (131) has a protruding groove (137) formed in the direction of the rotary weight (133) so that the rotary weight (133) can move in the direction of P1 while expanding the protruding groove (137), and is open in the direction of the fixing nut so that the bolt body (132) can be inserted into the screw cover (131).

[0046] The bolt body (132) has screw threads formed on its outer circumference and a concave groove (138) formed in the direction of the rotary weight (133), and a pinhole (134) may be formed in the concave groove (138). Additionally, a fixing nut (136) is provided at the opposite end of the bolt body (132) so that when force is applied in the direction of P1, the bolt body (132) can move inside the screw cover (131) along the direction of P1.

[0047] At this time, the rotary weight (133) comes out through the protruding groove (137) provided at the end of the screw cover (131), and its shape is as shown in FIG. 5.

[0048] The rotary weight (133) is composed of a weight (133a) and a weight support (133b), and a fastening hole (135) may be formed in the weight support (133b). Additionally, the rotary weight (133) may be fixed in a concave groove (138) by a fastening pin (133c).

[0049] The rotating weight (133) has a load of the weight (133a) that is 2 to 5 to 10 times heavier than the weight support (133b), and the weight support (133b) does not correspond to the center of gravity of the rotating weight (133).

[0050] That is, since the center of gravity of the rotary weight (133) is uneven, it corresponds to a structure that bends along the direction of gravity when not supported by the screw cover (131). Therefore, when an external force is applied in the P direction by the fixing nut (136), the rotary weight (133) is disengaged from the protruding groove (137) provided at the end of the screw cover (131), and the weight (133a) bends into an "L" shape at the weight support (133b). This will be explained with reference to FIG. 6.

[0051] Figure 6 illustrates the shape of a rotating weight bent along the direction of gravity.

[0052] Referring to FIG. 6, it can be seen that the rotary weight (133) is bent into an L-shape along the direction of gravity after being removed from the protruding groove (137). When the rotary weight (133), with its center of gravity concentrated on the weight (133a), is removed from the protruding groove (137) provided at the end of the screw cover (131), it rotates in the direction of gravity around the fastening pin (133c) to take the shape shown in FIG. 6. Accordingly, the end of the first fixing bolt (130) does not detach from the multi-stage grid (120) even if the fixing nut (136) is pulled from the outside by the weight (133) bent into an L-shape, and it becomes difficult to remove or dismantle the fence (100) according to the embodiment. Although various devices installed on bridges are vulnerable to theft or damage, the fence (100) according to the embodiment has the advantage of being resistant to theft or damage because it is difficult to dismantle itself.

[0053] 1. First embodiment

[0054] FIGS. 7 to 10 illustrate structural diagrams of a fastening structure according to a first embodiment.

[0055] First, referring to FIG. 7, an example is shown in which a second fixing bolt (140) is inserted through a second perforation hole (126) formed in a multi-stage grid (120), and then a first fixing bolt (130) described in FIG. 4 to 6 is inserted crosswise through a first perforation hole (125) to be fixed.

[0056] Referring to FIG. 7, the second fixing bolt (140) may be provided with a head portion (141) having screw threads formed on its outer circumference and a screw head provided at its end, and a bolt body (142) having screw threads formed on its outer and inner circumferences, with an insertion hole (143) formed in one area to be fastened in an intersecting manner with the first fixing bolt (130), and having a bolt structure formed by screw coupling with the outer circumference of the head portion (141) on its inner circumference, and having its end fastened with a fixing nut. After the second fixing bolt (140) is inserted into the multi-stage grid (120), the first fixing bolt (130) is inserted crosswise toward the insertion hole (143) as shown in FIG. 8, and when the fixing nut (136) provided on the side of the first fixing bolt (130) receives an external force and the weight (133a) is removed from the screw cover (131), the weight is bent into an "L" shape as shown in FIG. 9, and the side shape becomes the shape shown in FIG. 6.

[0057] Afterwards, the second fixing bolt (140) is screwed together by a nut (145) to form the shape shown in FIG. 10.

[0058] Due to the cross-fastening method of the first fixing bolt (130) and the second fixing bolt (140), the movement of the second fixing bolt (140) is restricted by the first fixing bolt (130). Even if the nut (145) is removed in the fastening state shown in FIG. 10, the second fixing bolt (140) remains connected to the first fixing bolt (130), so the second fixing bolt (140) does not detach from the multi-stage grid (120). That is, in the fence (100) according to the embodiment, only the nut (145) can be stolen or damaged, while the first fixing bolt (130) and the second fixing bolt (140) for fixing the multi-stage grid (120), the extension support (110), and the multi-stage grid (120) cannot be dismantled.

[0059] 2. Second embodiment

[0060] FIG. 11 illustrates a structural diagram of a second fixing bolt according to a second embodiment.

[0061] Referring to FIG. 11, the second fixing bolt (240) according to the second embodiment may be configured to include a head portion (241), a bolt body (242), an insertion hole (243), and an anti-detachment cap (244).

[0062] The head portion (241) has screw threads formed on its outer circumference and a screw head (241a) provided at its end. The bolt body (242) has an anti-detachment cap (244) provided at its end and screw threads formed on its inner circumference, and an insertion hole (243) is formed in one area to insert the first fixing bolt (130), and is screw-coupled to the outer circumference of the head portion (241) on its inner circumference to form a bolt structure.

[0063] The second fixing bolt (240) has a detachment prevention cap (244) fixed to the end of the bolt body (242). In the first embodiment described above, the nut (145) was detachable, but the second embodiment is characterized by preventing the nut (145) from being detachable. The rest is fastened and fixed to the multi-stage grid (120) in the same way as in the first embodiment, so redundant descriptions are omitted.

[0064] 3. Third Embodiment

[0065] Referring to FIG. 12, the second fixing bolt (340) according to the third embodiment is composed of a first bolt body (341) and a second bolt body (342) in which the end portion is cut along the longitudinal direction and extends with a step difference from the outer periphery. The first bolt body (341) and the second bolt body (342) are cut so that their end portions interlock to form cut portions (341a, 342a), and when the end portions interlock, an insertion hole (343) may be formed in the center. To this end, the first bolt body (341) and the second bolt body (342) may have the same insertion hole (343) formed in the same position so that when they are fastened together, the insertion hole (343) may be formed in common.

[0066] Additionally, a screw head (341b) is formed on one end of the first bolt body (341), and a screw head (342b) is formed on one end of the second bolt body (342), so that after the second fixing bolt (340) is cross-fastened with the first fixing bolt (130), no part can be detached or lost from the multi-stage grid (120).

[0067] After the first bolt body (341) and the second bolt body (342) are engaged inside the multi-stage grid (120), the first fixing bolt (130) is vertically intersected, resulting in the form shown in FIG. 13. Since the first fixing bolt (130) vertically intersects the first bolt body (341) and the second bolt body (342), and the screw head (341b) of the first bolt body (341) and the screw head (342b) of the second bolt body exposed outside the multi-stage grid (120) are formed integrally with the first bolt body (341) and the second bolt body (342), respectively, there are no parts that will be lost due to external force unless the multi-stage grid (120) is destroyed.

[0068] In the structure according to the third embodiment, the fastening structure is not lost at all except when demolished using heavy equipment.

[0069] 4. Fourth Embodiment

[0070] Referring to FIG. 14, the second fixing bolt (440) according to the fourth embodiment is composed of a first bolt body (441) and a second bolt body (442), and, as in the third embodiment, the first bolt body (441) and the second bolt body (442) have a longitudinal region cut along the longitudinal direction, and the cut regions interlock to form a single bolt structure.

[0071] The second fixing bolt (440) according to the fourth embodiment has a fastening structure similar to that of the third embodiment, but has the difference that one side of the second fixing bolt (440) is fixed by a nut (445). Accordingly, the end of the first bolt body (441) is exposed to the outside of the multi-stage grid (120) without a screw head and with screw threads formed thereon, and is differentiated from the third embodiment in that the exposed end is fixed by a nut (145). This difference is intended to allow the second fixing bolt (440) to be easily inserted and fixed within the multi-stage grid (120). In the third embodiment, the first bolt body (341) and the second bolt body (342) are inserted into the multi-stage grid (120) from different directions, whereas in the fourth embodiment, only the second bolt body (441) of the second fixing bolt (440) is inserted into the multi-stage grid (120) and then fixed with a nut (145). This improves workability when the first fixing bolt (130) and the second fixing bolt (440) are fastened vertically in an intersecting manner within the multi-stage grid (120), thereby enabling the fence (100) to be erected in a shorter time compared to the third embodiment.
