Description

Technical Field

[0001] The invention disclosed in the present application relates to the installation technology of a fence installed so as to surround the sites of various facilities, road areas, etc. More specifically, it relates to a connection structure for attaching a climbing prevention panel for intrusion prevention to the upper part of such a fence.

Background Art

[0002] In order to prevent intrusion into the sites of various facilities, road areas, and other specific areas related to public and private properties, a fence is installed so as to surround the area. Many of such fences are configured by attaching shielding panels such as lattice-shaped, net-shaped, or plate-shaped between columns erected at appropriate intervals. Patent Documents 1 to 6, etc. disclose the structure of a fence that connects a shielding panel formed by arranging metal wire rods in a vertical and horizontal lattice pattern to columns.

[0003] Also, Patent Documents 7 and 8 disclose a structure in which an inclined "climbing prevention" is attached to the upper part of the fence to make it more difficult for intruders such as burglars to enter. The applicant of the present application has also commercialized a fence that can connect a lattice-shaped climbing prevention panel to the upper part and disclosed it in Non-Patent Document 1.

[0004] Figs. 1 to 4 show the basic structure of the fence disclosed in Non-Patent Document 1 and the connection structure of the climbing prevention panel. This fence 1 is composed of a plurality of columns 2 buried in a foundation 11 and erected at a predetermined interval, a plurality of main body panels 3 attached to the finding surface of the columns 2 from the lower part to the middle part or near the upper part of the columns 2, and a plurality of climbing prevention panels 4 attached to the upper part of the columns 2.

[0005] The support column 2 is a member made of, for example, a metal square pipe or the like, and has an upright portion 23 that stands vertically from the foundation 11 and a tilted portion 24 that extends obliquely and refracts from the upper part of the upright portion 23. The illustrated support column 2 is formed such that the upright portion 23 and the tilted portion 24 are integrally continuous, but there is also a form in which the upright portion 23 and the tilted portion 24 are formed separately and joined together. The height of the upright portion 23 is appropriately selected according to the circumstances of the installation location and the like. Also, regarding the tilted portion 24, either a form that tilts inward (inwardly inclined form) or a form that tilts outward (outwardly inclined form) within the area surrounded by this fence body 1 can be selected according to the circumstances of the installation location and the like (see FIGS. 2 and 3). The inclination of the tilted portion 24 is set at approximately 30 degrees with respect to the vertical line. At an appropriate position in the middle of the support column 2, a substantially J-shaped hook member 25 that penetrates the support column 2 in the inner and outer directions of the surrounded area is attached.

[0006] The main body panel 3 is a planar member that is formed by joining metal vertical members 31 and horizontal members 32 in a grid pattern and is substantially rectangular when viewed from the front. This main body panel 3 is attached to the attachment surface of the upright portion 23 of the support column 2 (usually the attachment surface on the outer side of the surrounded area) by hanging the horizontal member 32 on the hook member 25 attached to the upright portion 23 of the support column 2. In this specification, in the plane direction of the attachment surface, the side where the main body panel 3 is attached (the side away from the support column 2) is referred to as "outer side / outward", and the opposite side is referred to as "inner side / inward" to describe the relative positional relationship of parts and members and the direction of movement. This main body panel 3 is assembled such that the inner horizontal member 32 abuts against the support column 2 and the outer vertical member 31 is away from the support column 2.

[0007] Adjacent main body panels 3 in the horizontal direction are connected via a connecting fitting 5 configured to sandwich the vertical members 31 at the ends of each other and the horizontal member 32 that intersects the vertical member 31 from both the inner and outer sides. When the height of the upright portion 23 is large, a plurality of main body panels 3 are also connected in the vertical direction.

[0008] In the vicinity of the upper end of the vertical member 31 in the main body panel 3, there are provided an inclined portion 311 bent outward (in the direction away from the support column 2) and a horizontal portion 312 folded back from the upper end of the inclined portion 311 toward the support column 2 side. And the uppermost horizontal member 32A is joined at the position connecting the horizontal portions 312 of the adjacent vertical members 31, and the second-stage horizontal member 32B from the top is joined at the position connecting the inclined portions 311 of the adjacent vertical members 31. The uppermost horizontal member 32A is arranged in the same vertical plane as the horizontal members 32 below the third stage from the top of the main body panel 3, and the second-stage horizontal member 32B is arranged at a position farther outward than the horizontal members 32 below the third stage. By the combination of the inclined portion 311 and the horizontal portion 312 bent and formed at the upper end of these vertical members 31 and the uppermost horizontal member 32A and the second-stage horizontal member 32B connecting them in the horizontal direction, the flexural rigidity in the vicinity of the upper edge of the main body panel 3 is strengthened. Further, a coupling form similar to this is provided in the vicinity of the lower edge of the main body panel 3 with the up and down directions reversed.

[0009] The stealth panel 4 is also a substantially rectangular surface material formed by joining metal vertical members 41 and horizontal members 42 in a grid pattern, similar to the main body panel 3. This stealth panel 4 is also assembled such that the inner horizontal member 42 abuts against the support column 2 and the outer vertical member 41 is away from the support column 2, and the horizontal member 42 is hooked on the hook member 25 attached to the tilting portion 24, and is attached to the finding surface (the finding surface on the same side as the main body panel 3) of the tilting portion 24. The adjacent stealth panels 4 in the horizontal direction are connected via a connecting fitting, similar to the main body panel 3.

[0010] Then, the upper edge of the main body panel 3 and the lower edge of the return panel 4 are connected using the connecting fitting 6 shown in FIG. 4. This connecting fitting 6 is configured to sandwich the uppermost horizontal member 32A and the second-stage horizontal member 32B of the main body panel 3 and the lowermost horizontal member 42C of the return panel 4 by a pair of inner and outer clamping pieces 61, 62 bent in a "く" shape in side view. On the front surfaces of the inner clamping piece 61 and the outer clamping piece 62 facing away from each other, stiffening ribs 63, 64 for restraining their respective bending angles are formed in two rows on the left and right by embossing from the opposing surface sides.

[0011] The lower ends of the inner clamping piece 61 and the outer clamping piece 62 are integrally continuous via a folded-back portion 65 that is substantially U-shaped in side view. The folded-back portion 65 is provided with a narrow width at both ends in the width direction of both clamping pieces 61, 62 to facilitate elastic deformation in the bending direction. The inner diameter of the folded-back portion 65 is formed to be slightly larger than the outer diameter of the second-stage horizontal member 32B from the top of the main body panel 3.

[0012] The bent portions of the inner clamping piece 61 and the outer clamping piece 62 bulge in a substantially arc shape in side view toward the back side of each other, and an intermediate holding portion 66 is formed between them. The uppermost horizontal member 32A of the main body panel 3 is held by this intermediate holding portion 66. The upper parts of the inner clamping piece 61 and the outer clamping piece 62 also bulge in a substantially arc shape in side view toward the back side of each other, and an upper-end holding portion 67 is formed between them. The lowermost horizontal member 42C of the return panel 4 is held by this upper-end holding portion 67.

[0013] A fastening tool insertion hole (not shown) is formed between the intermediate holding portion 66 and the upper-end holding portion 67 of the inner clamping piece 61, while a female screw hole 69 is formed by burring and tapping at the location facing the fastening tool insertion hole of the outer clamping piece 62. The connecting fitting 6 formed in this way is mounted by expanding the opposing interval on the upper end sides of both clamping pieces 61 and 62 and sandwiching the second horizontal member 32B from the top, the topmost horizontal member 32A, and the lowermost horizontal member 42C of the return panel 4 of the main body panel 3 from below. Then, with the three horizontal members 32A, 32B, and 42C held by the vicinity of the folded-back portion 65, the intermediate holding portion 66, and the upper end holding portion 67 respectively, a fastening tool 7 such as a hexagon bolt is inserted into the fastening tool insertion hole from the inside of the connecting fitting 6 and fastened to the female screw hole 69. In this way, the two horizontal members 32A and 32B on the main body panel 3 side and the horizontal member 42C on the return panel 4 side are clamped via the connecting fitting 6 in a "く" shape in side view, so that the main body panel 3 and the return panel 4 are firmly connected so as not to bend or shake in the inner and outer directions, and the gap between the two panels is beautifully shielded.

Summary of the Invention

Problems to be Solved by the Invention

[0016] The above-mentioned fence body 1 disclosed in Non-Patent Document 1 is configured with the intention that the connecting fitting 6 shown in FIG. 4 can be commonly used in the inner infiltration form shown in FIG. 2 and the outer infiltration form shown in FIG. 3. However, in reality, as shown in FIG. 5, due to variations such as the delicate dimensional relationship between the attachment positions of the support column 2 and the infiltration panel 4, and the positional accuracy of the hook member 25 attached to the bent portion of the support column 2 (the machining accuracy of the insertion hole formed in the support column 2), in the inner infiltration form and the outer infiltration form, the position of the horizontal wire 42C on the infiltration panel 4 side with respect to the two horizontal wires 32A and 32B on the main body panel 3 side may deviate by about several millimeters in the inner and outer direction (X direction) and the height direction (Y direction). In that case, when the connecting fitting 6 shown in FIG. 4 clamps the two horizontal wires 32A and 32B on the main body panel 3 side and the horizontal wire 42C on the infiltration panel 4 side, in either the inner infiltration form or the outer infiltration form, the shape of the connecting fitting 6 and the positional relationship with each of the horizontal wires 32A, 32B, and 42C will become inconsistent. The deviation in the inner and outer direction is generally absorbed by the out-of-plane deflection deformation of the infiltration panel 4, but the deviation in the height direction causes unreasonable bending deformation in any of the horizontal wires 32A, 32B, and 42C, or the gap between the main body panel 3 and the infiltration panel 4 cannot be evenly maintained.

[0017] The invention disclosed in the present application was conceived to improve such inconveniences. Even when the position of the horizontal wire 42C on the side of the return panel 4 is displaced in the height direction between the internal return form and the external return form, a connecting fitting is provided that can easily sandwich the two horizontal wires 32A and 32B on the side of the main body panel 3 and the single horizontal wire 42C on the side of the return panel 4, thereby improving the construction accuracy of the return panel 4 in the fence body 1.

Means for Solving the Problems

[0018] To achieve the above object, the return panel connection structure of the fence body according to the invention disclosed in the present application is such that, for a support column having an upright portion and a tilting portion extending upward therefrom, a main body panel is attached to the mounting surface of the upright portion, and a return panel is attached to the mounting surface of the tilting portion. A connection structure of the return panel in which two horizontal wires arranged at the upper edge of the main body panel and a single horizontal wire arranged at the lower edge of the return panel are clamped from both the inside and outside through the following connecting fitting. The connecting fitting has a pair of inner and outer clamping pieces whose intermediate portions are bent at a predetermined angle and whose bending angles are restricted, and a folding portion that connects the lower end portions of the two clamping pieces and is elastically deformable in a direction to expand and contract the opposing interval between the two clamping pieces. Intermediate holding portions that bulge toward the back sides of each other are formed at the bending locations of the outer clamping piece and the inner clamping piece. At the upper portions of the outer clamping piece and the inner clamping piece, upper end holding portions having positioning means at two locations each inside the opposing surfaces of the tips of each other are formed. In a state where the two horizontal wires on the side of the main body panel are held by the vicinity of the folding portion and the intermediate holding portion, and the single horizontal wire on the side of the return panel is held by the upper end holding portion, the pair of inner and outer clamping pieces are configured to be fastened through a fastener. The positioning means of the upper end holding portion is provided so as to be able to regulate both the position of the horizontal wire when the return panel is installed in the internal return form and the position of the horizontal wire when the return panel is installed in the external return form, adopting the basic configuration as described above.

[0019] According to this basic configuration, even when the position of the horizontal wire on the return panel side is displaced in the height direction between the inner hiding form and the outer hiding form, the two horizontal wires on the main body panel side and the one horizontal wire on the return panel side can be easily clamped by a pair of inner and outer clamping pieces.

[0020] Furthermore, in the return panel connection structure of the fence body according to the invention disclosed in the present application, when the pair of inner and outer clamping pieces are fastened via a fastener, the horizontal wire held within the folded portion abuts against one of the pair of inner and outer clamping pieces, and the horizontal wire held within the intermediate holding portion abuts against the other of the pair of inner and outer clamping pieces, adopting an additional configuration as such.

[0021] Furthermore, in the return panel connection structure of the fence body according to the invention disclosed in the present application, in the inner hiding form and the outer hiding form, the clamping pieces on the side that abut against the horizontal wires held by the folded portion and the intermediate holding portion respectively are opposite inside and outside, adopting an additional configuration as such.

Effect of the Invention

[0022] According to the invention disclosed in the present application, by using a connecting fitting with an improved cross-sectional shape, in both the inner hiding form and the outer hiding form, the two horizontal wires on the main body panel side and the one horizontal wire on the return panel side can be easily clamped. As a result, the connection strength between the main body panel and the return panel is increased, and the gap between the main body panel and the return panel is beautifully maintained.

Embodiments for Carrying out the Invention

[0024] Hereinafter, embodiments of the invention disclosed in the present application will be described with reference to the drawings. In the following, the same components as those of the conventional fence body 1 shown in FIGS. 1 to 5 are denoted by common reference numerals, and detailed descriptions thereof are omitted. FIG. 6 shows the configuration of the connecting fitting 60 adopted by the invention disclosed in the present application, and FIGS. 7 and 8 show the connection structure between the main body panel 3 and the return panel 4 using the connecting fitting 60.

[0025] The connecting fitting 60 is applied to the same fence body 1 as shown in FIGS. 1 to 3 and FIG. 5, and is formed of, for example, a stainless steel material or the like. Similar to the conventional connecting fitting 6 shown in FIG. 4, this connecting fitting 60 is also formed by a pair of inner and outer clamping pieces 61 and 62 whose middle parts are bent in a "く" shape in side view at a predetermined angle, and sandwich the uppermost horizontal wire 32A and the second-stage horizontal wire 32B of the main body panel 3, and the lowermost horizontal wire 42C of the eaves panel 4. On the front surfaces of the inner clamping piece 61 and the outer clamping piece 62 that face away from each other, reinforcing ribs 63 and 64 for restraining so that their respective bending angles do not change are formed in two rows on the left and right by punching from the opposite surface side of each other.

[0026] The lower ends of the inner clamping piece 61 and the outer clamping piece 62 are integrally continuous via a folding part 65 that is substantially U-shaped in side view. Since the folding part 65 is provided with a narrow width at both ends in the width direction of both clamping pieces 61 and 62, both clamping pieces 61 and 62 are held in a state where they are easily elastically deformed in the direction of expanding and contracting the opposing interval between them. The inner diameter of the folding part 65 is formed to be slightly larger than the outer diameter of the second-stage horizontal wire 32B from the top of the main body panel 3.

[0027] The bent portions of the inner clamping piece 61 and the outer clamping piece 62 bulge in a substantially arc shape in side view toward the back side of each other, and an intermediate holding part 660 is formed between them. The uppermost horizontal wire 32A of the main body panel 3 is held in this intermediate holding part 660. However, this intermediate holding part 660 is formed so that its substantial inner diameter is slightly larger than that of the intermediate holding part 66 of the conventional connecting fitting 6 shown in FIG. 4.

[0028] The upper ends of the inner clamping piece 61 and the outer clamping piece 62 face each other with their tips curved in an arc shape in a side view so as to approach each other. Inside their opposing surfaces, ridge 671 with a substantially semi-circular cross-section extending in the lateral direction is formed at two locations each in the vertical direction. These ridges 671 at two locations each inside and outside are arranged such that the vertical interval is about two to three times the diameter of the lowermost horizontal member 42C of the deflection panel 4. And the space surrounded by these ridges 671 at two locations each inside and outside becomes the upper end holding portion 670, and the lowermost horizontal member 42C of the deflection panel 4 is held inside the upper end holding portion 670. That is, these four ridges 671 in total constitute positioning means for regulating the highest position and the lowest position in the height direction of the horizontal member 42C held by the upper end holding portion 670 in both the inner deflection form and the outer deflection form.

[0029] Furthermore, between the ridges 671 at two locations each inside and outside, linear protrusions 672 smaller than the ridges 671 are formed to extend in the lateral direction, five in each case in the illustrated form. These linear protrusions 672 function as anti-slip means for preventing the horizontal member 42C held inside the upper end holding portion 670 from shifting in the vertical direction.

[0030] A fastener insertion hole 680 is formed between the intermediate holding portion 660 and the upper end holding portion 670 in the inner clamping piece 61. This fastener insertion hole 680 is formed as a long hole extending in the vertical direction. On the other hand, a female screw hole 69 is formed by burring and tapping at the location facing the fastener insertion hole 680 in the outer clamping piece 62.

[0031] The connecting fitting 60 formed in this way is mounted by pushing and expanding the opposing interval at the upper end side of both clamping pieces 61, 62 so as to sandwich the second horizontal member 32B from the top, the uppermost horizontal member 32A, and the lowermost horizontal member 42C of the deflection panel 4 from below. And with the three horizontal members 32A, 32B, 42C held by the vicinity of the folded-back portion 65, the intermediate holding portion 660, and the upper end holding portion 670 respectively, a fastener 7 such as a hexagon bolt is inserted into the fastener insertion hole 680 of the inner clamping piece 61 from the inside, and the fastener 7 is fastened to the female screw hole 69 of the outer clamping piece 62.

[0032] Figure 7 shows the holding state of the horizontal wire members in the inward deflection form using the aforementioned connecting fitting 60. In the inward deflection form, the position of the horizontal wire member 42C on the deflection panel 4 side is relatively biased upward and inward with respect to the two horizontal wire members 32A and 32B on the main body panel 3 side. Therefore, when the connecting fitting 60 with the bending angle of the middle part restricted is attached to those three horizontal wire members 32A, 32B, and 42C and the fastener 7 is fastened, as shown by the white triangle symbol (△) in the figure, the uppermost horizontal wire member 32A of the main body panel 3 abuts against the outer clamping piece 62 at the middle holding part 660, and the second-stage horizontal wire member 32B of the main body panel 3 abuts against the inner clamping piece 61 near the folding part 65. In this state, the lowermost horizontal wire member 42C of the deflection panel 4 is clamped by the inner clamping piece 61 and the outer clamping piece 62 near the highest position within the upper-end holding part 670.

[0033] Figure 8 shows the holding state of the horizontal wire members in the outward deflection form using the aforementioned connecting fitting 60. In the outward deflection form, the position of the horizontal wire member 42C on the deflection panel 4 side is relatively biased downward and outward with respect to the two horizontal wire members 32A and 32B on the main body panel 3 side. Therefore, when the connecting fitting 60 with the bending angle of the middle part restricted is attached to those three horizontal wire members 32A, 32B, and 42C and the fastener 7 is fastened, as shown by the white triangle symbol (△) in the figure, the uppermost horizontal wire member 32A of the main body panel 3 abuts against the inner clamping piece 61 at the middle holding part 660, and the second-stage horizontal wire member 32B of the main body panel 3 abuts against the outer clamping piece 62 near the folding part 65. In this state, the lowermost horizontal wire member 42C of the deflection panel 4 is clamped by the inner clamping piece 61 and the outer clamping piece 62 near the lowest position within the upper-end holding part 670.

[0034] In this way, by improving the cross-sectional shape of the connecting fitting 60 and adding positioning means for expanding the holding range of the horizontal wire 42C on the side of the deflection panel 4 in the upper end holding portion 670 in particular in the height direction, even when the position of the horizontal wire 42C shifts in the height direction between the inner deflection form and the outer deflection form, it becomes possible to clamp the two horizontal wires 32A and 32B on the main body panel 3 side and the single horizontal wire 42C on the deflection panel 4 side without difficulty.

[0035] FIG. 9 shows a deformed form of the connecting fitting, and FIGS. 10 and 11 show the connecting structure between the main body panel 3 and the deflection panel 4 using the connecting fitting. The connecting fitting 600 shown in FIG. 9 is a modification of the cross-sectional shape of the portion above the intermediate holding portion 660 (near the portion that sandwiches the lowermost horizontal wire 42C of the deflection panel 4) in the connecting fitting 60 shown in FIG. 6. Since the portion below the intermediate holding portion 660 (the portion that sandwiches the uppermost horizontal wire 32A and the second horizontal wire 32B of the main body panel 3) is substantially the same as the above-described connecting fitting 60, the same parts are denoted by the same reference numerals and the description thereof is omitted.

[0036] In the connecting fitting 600 of FIG. 9, the portions (near the portion where the fastener 7 is inserted) between the intermediate holding portion 660 and the upper end holding portion 670 in the inner clamping piece 61 and the outer clamping piece 62 are refracted so as to be constricted toward the opposing surface sides of each other, and the upper end holding portion 670 is formed so as to have a substantially oval combined cross-section. In this upper end holding portion 670, the curved edges 673 at the upper ends in the inner clamping piece 61 and the outer clamping piece 62 and the bent corner portions 674 on the fastener 7 side in the inner clamping piece 61 and the outer clamping piece 62 constitute positioning means for regulating the highest position and the lowest position of the horizontal wire 42C, respectively. And also in this upper end holding portion 670, the vertical interval between the curved edge 673 at the upper end and the bent corner portion 674 on the fastener 7 side is set to be about two to three times the diameter of the lowermost horizontal wire 42C of the deflection panel 4.

[0037] The connecting fitting 600 formed in this way is also the same as the aforementioned connecting fitting 60 with respect to the holding state of the horizontal member. That is, in the inner deflection form of FIG. 10, the uppermost horizontal member 32A of the main body panel 3 abuts against the outer clamping piece 62 at the intermediate holding portion 660, and the second-stage horizontal member 32B of the main body panel 3 abuts against the inner clamping piece 61 near the folding-back portion 65. In this state, the lowermost horizontal member 42C of the return panel 4 is clamped between the inner clamping piece 61 and the outer clamping piece 62 near the highest position (upper curved edge 673) within the upper holding portion 670. Also, in the outer deflection form of FIG. 11, the uppermost horizontal member 32A of the main body panel 3 abuts against the inner clamping piece 61 at the intermediate holding portion 660, and the second-stage horizontal member 32B of the main body panel 3 abuts against the outer clamping piece 62 near the folding-back portion 65. In this state, the lowermost horizontal member 42C of the return panel 4 is clamped between the inner clamping piece 61 and the outer clamping piece 62 near the lowest position (bending corner portion 674) within the upper holding portion 670.

[0038] Further, according to this connecting fitting 600, the periphery of the fastening tool insertion hole 680 into which the fastening tool 7 is inserted and the periphery of the female screw hole 69 come into and out of contact with each other in a state of being close to parallel to each other. Therefore, the fastening tool 7 is fastened smoothly and surely, and when the fastening tool 7 is tightened further with the horizontal member 42C sandwiched by the upper holding portion 670, it is also possible to suppress the expansion of the opposing interval on the upper end side of the upper holding portion 670.

[0039] As described above, if the connecting fittings 60 and 600 according to the invention disclosed in the present application are adopted, in both the inner deflection form and the outer deflection form, the two horizontal members 32A and 32B on the main body panel 3 side and the one horizontal member 42C on the return panel 4 side can be clamped without difficulty. As a result, the connection strength between the main body panel 3 and the return panel 4 increases, and the gap between the main body panel 3 and the return panel 4 is beautifully maintained. Thus, with one type of connecting fittings 60 and 600, it is possible to significantly improve the construction accuracy of the return panel 4 in both the inner deflection form and the outer deflection form.

The names of the components used in the claims and the specification are for convenience in facilitating the specific understanding of the invention, and such names do not unduly limit the concept and properties of the components.
