Description

[Technical Field]

[0001] The present invention relates to a reinforcing bracket and a support pole mounting structure. [Background technology]

[0002] Conventionally, pedestrian and bicycle fences, vehicle guardrails, and other guardrails are known as guardrails built along roads. These guardrails are constructed by connecting guard pipes, such as fence beams, between multiple posts erected on the road. One method for efficiently attaching the fence beams to the posts is to use hollow post mounting brackets. This method allows the posts and the fence beam to be easily connected by inserting both ends of the fence beam into the hollow spaces of multiple post mounting brackets attached to each of the multiple posts.

[0003] Patent Document 1 discloses a support mounting fixture that is attached to a support and is a hollow body having an opening at the top. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-187370 Summary of the Invention [Problem to be solved by the invention]

[0005] The pole mounting bracket disclosed in Patent Document 1 temporarily positions the end of the fence beam in a hollow space inside the bracket so that the angle can be adjusted to match the road gradient, reducing the number of workers required for installation and improving work efficiency by reducing the number of installation steps. However, the conventional pole mounting bracket 8 disclosed in Patent Document 1 has an opening at the top. Therefore, when a vertically downward load is applied to the fence beam 9, as shown in Figure 8, for example, there is a risk that the bracket will bend relative to the fence beam 9 around the screw fastener B7 for fixing to the pole 7 and the screw fastener B9 for fixing to the fence beam 9. As a result, the bent shape and the end face of the fence beam 9 become visible, resulting in poor compatibility and appearance. Furthermore, safety concerns remain, such as gaps at the bends that could pinch pedestrians' hands when they touch them.

[0006] The present invention was devised in consideration of the above-mentioned problems, and its purpose is to provide a reinforcing bracket and a pillar mounting structure that improves the compatibility and safety of the pillar mounting structure. [Means for solving the problem]

[0007] The reinforcing bracket of the first invention is a reinforcing bracket that is attached to an upright post and has an opening at the top through which the end of a fence beam is inserted, and is fastened to a post mounting bracket, and is characterized in that it comprises an upper plate portion that covers at least a part of the opening, a pair of side plate portions that extend downward from the upper plate portion so as to face each other and spaced apart on either side of the end of the fence beam, and a pair of holes drilled in each of the pair of side plate portions and through which screw fasteners for fastening to the post mounting bracket are inserted, and the upper plate portion is located at least on the opposite side of the post from the fastening axis when viewed in the fastening direction of the screw fasteners.

[0008] The reinforcing metal fitting according to the second invention is the first invention, characterized in that the upper plate portion is further provided on the side of the support pillar relative to the fastening shaft when viewed in the fastening direction.

[0009] The reinforcing bracket of the third invention is characterized in that, in the second invention, the upper plate portion has a locking portion that always contacts the upper end of the pillar mounting bracket on the pillar side of the fastening axis when viewed in the fastening direction.

[0010] The reinforcing metal fitting of the fourth invention is characterized in that, in any of the first to third inventions, it further comprises an extension plate portion extending downward from the upper plate portion, in the insertion direction of the fence beam and on the side of the post rather than the fastening axis when viewed in the fastening direction.

[0011] The post mounting structure of the fifth invention comprises an upright post, a post mounting bracket attached to the post and having an opening at the top, a fence beam whose end is inserted inside the post mounting bracket, an upper plate that is fastened to the post mounting bracket via a screw fastener and covers at least part of the opening, a pair of side plates extending downward from the upper plate so as to face each other and spaced apart across the end of the fence beam, and a pair of holes drilled in each of the pair of side plates and through which the screw fasteners are inserted, and the upper plate is located at least on the opposite side of the post from the fastening axis when viewed in the fastening direction of the screw fasteners. [Effects of the Invention]

[0012] According to the first to fourth inventions, the reinforcing bracket covers the upper opening of the post mounting bracket and is equipped with at least an upper plate portion that is located on the opposite side of the post from the fastening axis when viewed in the fastening direction of the screw fastener. Therefore, when a vertically downward load is applied to the fence beam, the upper plate portion is engaged with the upper surface of the fence beam, preventing the post mounting bracket from moving in a direction that would cause it to bend relative to the fence beam around the screw fastener. This improves the compatibility and safety of the post mounting structure.

[0013] In particular, according to the second invention, the upper plate portion is provided further toward the post than the fastening axis when viewed in the fastening direction. Therefore, when a vertically downward load is applied to the fence beam, the upper plate portion is more securely engaged with the upper surface of the fence beam, further preventing the post mounting bracket from moving in a bending direction relative to the fence beam around the screw fastener. This further improves the compatibility and safety of the post mounting structure. Furthermore, when the upper plate portion covers the upper surface of the end of the fence beam, the fence beam is less likely to be exposed. This further improves the compatibility of the post mounting structure.

[0014] In particular, according to the third aspect of the invention, the upper plate has a locking portion that always contacts the upper end of the post mounting bracket on the side closer to the post than the fastening axis when viewed in the fastening direction. This allows the upper plate to be more securely locked to the upper end of the post mounting bracket via the locking portion, in addition to the upper surface of the fence beam, further preventing the post mounting bracket from moving in a bending direction relative to the fence beam around the screw fastener. This further improves the compatibility and safety of the post mounting structure.

[0015] In particular, according to the fourth aspect of the present invention, an extension plate is provided that extends downward from the upper plate, in the direction of insertion of the fence beam and closer to the post than the fastening axis when viewed in the fastening direction. Therefore, by covering the end side of the fence beam with the extension plate, the fence beam is less likely to be exposed. This further improves the compatibility of the post mounting structure.

[0016] According to the fifth aspect of the present invention, the post mounting structure includes an upper plate that covers the upper opening of the post mounting bracket and is located on the opposite side of the post from the fastening axis of the screw fastener when viewed in the fastening direction. Therefore, when a vertical load is applied to the fence beam, the upper plate is locked onto the top surface of the fence beam, preventing the post mounting bracket from bending relative to the fence beam around the screw fastener. This improves the compatibility and safety of the post mounting structure. [Brief explanation of the drawings]

[0018] An example of a reinforcing bracket 1 and a pole mounting structure 100 according to an embodiment of the present invention will be described in detail below with reference to the drawings. In each figure, a first horizontal direction X is defined, one direction perpendicular to the first horizontal direction X is defined as a second horizontal direction Y, and a direction perpendicular to both the first horizontal direction X and the second horizontal direction Y is defined as a vertical direction Z. The configurations in each figure are shown schematically for the purpose of explanation, and for example, the size of each component and the size comparison between components may differ from those shown in the figures.

[0019] (Reinforcing bracket 1) An example of the reinforcing metal fitting 1 in this embodiment will be described with reference to the drawings.

[0020] The reinforcing bracket 1 is attached to an erected support (conventional support 7) and fastened to a support mounting bracket (conventional support mounting bracket 8) through which the end of a fence beam (conventional fence beam 9) is inserted and which has an opening at the top.

[0021] As shown in Figures 1(a) and 1(b), for example, the reinforcing bracket 1 comprises an upper plate 2, a pair of side plate sections 3 extending downward from the upper plate section 2 so as to face each other and be spaced apart, and a pair of holes 4 drilled in each of the pair of side plate sections 3 and through which screw fasteners (conventional screw fasteners B9) for fastening to the column mounting bracket 8 are inserted. The reinforcing bracket 1 has, for example, an internal space Q enclosed by the upper plate section 2 and the pair of side plate sections 3. The reinforcing bracket 1 may further comprise, for example, an extension plate section 5 extending downward from the upper plate section 2. For example, at least a portion of the AA side of the reinforcing bracket 1 is closed by the extension plate section 5, and the BB side has an opening.

[0022] The reinforcing bracket 1 is fastened to a pole mounting bracket 8 attached to a pole 7 erected on the AA side of Fig. 1(b) (see Fig. 3(a)). At this time, the reinforcing bracket 1 covers at least a portion of the opening that the pole mounting bracket 8 has above it, via the upper plate portion 2. The end of the fence beam 9 of the reinforcing bracket 1 is inserted into the internal space Q, for example, from the opening on the BB side of Fig. 1(b). The pair of side plate portions 3 of the reinforcing bracket 1 face each other and are spaced apart, sandwiching the end of the fence beam 9 inserted into the internal space Q.

[0023] The reinforcing bracket 1 is provided, for example, with its upper plate 2 on the opposite side of the fastening axis from the post 7 (the BB side in FIG. 1(b)) when viewed from the fastening direction of the screw fastener B9 (see FIG. 3(b)). The fastening direction of the screw fastener B9 is the second horizontal direction Y in FIGS. 1(a) and 1(b). The fastening axis of the screw fastener B9 refers to the direction in which the axial force (tightening force) generated when the screw fastener B9 is fastened acts. When the screw fastener B9 is inserted through a pair of boreholes 4, the fastening axis always intersects with the pair of boreholes 4. In this case, when a load is applied to the fence beam 9 in the vertical downward direction (the downward direction in the vertical direction Z), the upper plate 2 is engaged with the top surface of the fence beam 9, preventing the post mounting bracket 8 from bending relative to the fence beam 9 around the screw fastener B9. This improves the compatibility and safety of the post mounting structure 100.

[0024] The reinforcing metal fitting 1 is made of, for example, steel material. The reinforcing metal fitting 1 may be formed by deforming a single steel plate so that each component is continuous, or each component may be made of different materials and joined together by welding.

[0025] <Upper plate 2> The upper plate portion 2 covers at least a portion of the opening formed in the upper portion of the column mounting bracket 8. The upper plate portion 2 is provided, for example, at least on the opposite side of the fastening axis from the column 7 when viewed in the fastening direction of the screw fastener B9.

[0026] As shown in FIG. 1, for example, the upper plate 2 may be provided further toward the post 7 than the fastening axis when viewed in the fastening direction (the AA side in FIG. 1(b)). In this case, when a vertically downward load is applied to the fence beam 9, the upper plate 2 is more securely locked onto the upper surface of the fence beam 9, further preventing the post mounting bracket 8 from moving in a bending direction relative to the fence beam 9 around the screw fastener B9. This improves the compatibility and safety of the post mounting structure 100. Furthermore, if the upper plate 2 covers the upper surface of the end of the fence beam 9, the fence beam 9 is less likely to be exposed. This further improves the compatibility of the post mounting structure 100.

[0027] The upper plate portion 2 has a central plate portion 21, outer edge plate portions 22, and locking portions 23, as shown in, for example, FIGS. 1(a) and 1(b).

[0028] The upper plate portion 2 is made of, for example, a steel material. The upper plate portion 2 may be formed by deforming a single steel plate so that each component is continuous, or each component may be made of different materials and joined together by welding.

[0029] <Central plate part 21> The central plate portion 21 refers to the central region of the upper plate portion 2. The central plate portion 21 has a curved surface that bulges out on the side opposite to the internal space Q with respect to the outer edge plate portion 22, as shown in, for example, Figures 2(a) and 2(b).

[0030] The central plate 21 comes into contact with the rail beam 9 inserted into the internal space Q, for example, at its curved inner peripheral surface on the internal space Q side. In this case, compared to when the central plate 21 is flat, the contact area with the curved surface of the rail beam 9 is larger, making it difficult for vertically downward loads to be transmitted locally to the rail beam 9. This improves the durability of the post mounting structure 100.

[0031] The central plate 21 contacts the fence beam 9 inserted into the internal space Q, for example, at its inner peripheral surface that bulges out relative to the outer edge plate 22. In this case, compared to when the central plate 21 does not bulge out relative to the outer edge plate 22, the fence beam 9 is less likely to shift from the bulging inner peripheral surface toward the outer edge plate 22, making it easier to stably transmit vertically downward loads on the fence beam 9 to the bulging part of the central plate 21. This improves the manageability of the post mounting structure 100, for example, by determining when to replace the bulging part of the upper plate 2 based on the degree of damage or deterioration to the bulging part.

[0032] <Outer edge plate portion 22> The outer edge plate portion 22 refers to the outer edge region of the upper plate portion 2. The outer edge plate portion 22 has, for example, a flat plate shape.

[0033] The outer edge plate portion 22 extends continuously from, for example, an end portion of the central plate portion 21 in the second horizontal direction Y. The outer edge plate portion 22 has, for example, a pair of side plate portions 3 (side plate portion 31, side plate portion 32) extending continuously downward at the end portion.

[0034] <Latching portion 23> The locking portion 23 is a portion of the upper plate portion 2 that is locked to the support mounting bracket 8.

[0035] As shown in Figure 1(a), for example, the locking portion 23 is formed closer to the post 7 than the fastening axis when viewed in the fastening direction of the screw fastener B9, and is always in contact with the upper end of the post mounting bracket 8 (see Figures 3(b) and 4). In this case, the upper plate portion 2 is more securely locked to the upper end of the post mounting bracket 8 in addition to the upper surface of the fence beam 9 via the locking portion 23, further preventing the post mounting bracket 8 from moving in a bending direction relative to the fence beam 9 around the screw fastener B9 as an axis. This further improves the compatibility and safety of the post mounting structure 100.

[0036] <Pair of side plate portions 3> The pair of side plate portions 3 extend downward from the upper plate portion 2 so as to face each other and be spaced apart, as shown in Figures 2(a) and 2(b), for example. The pair of side plate portions 3 face each other and are spaced apart, sandwiching the end of the fence beam 9 inserted into the internal space Q therebetween.

[0037] The pair of side plate portions 3 includes, for example, a side plate portion 31 and a side plate portion 32. The pair of side plate portions 3 each have a pair of holes 4 formed therein.

[0038] <Pair of Perforations 4> The pair of holes 4 are drilled, for example, in each of the pair of side plate portions 3. Screw fasteners B9 for fastening the reinforcing bracket 1 to the pole mounting bracket 8 are inserted through the pair of holes 4.

[0039] The pair of bore holes 4 includes, for example, bore hole 41 and bore hole 42. The pair of bore holes 4 includes, for example, bore hole 41 drilled in side plate portion 31 and bore hole 42 drilled in side plate portion 32. The pair of bore holes 4 includes, for example, bore hole 41 and bore hole 42 facing each other and spaced apart on the fastening axis of one screw fastener B9.

[0040] <Extension plate part 5> The extension plate portion 5 extends downward from the upper plate portion 2. As shown in Fig. 1(a), for example, the extension plate portion 5 is formed on the support column 7 side relative to the fastening shaft when viewed in the fastening direction.

[0041] As shown in Figure 1(b), for example, the extension plate 5 is in the insertion direction of the fence beam 9 inserted into the internal space Q from the BB side, and extends downward from the upper plate 2 on the side of the post 7 closer to the fastening axis when viewed in the fastening direction. In this case, by covering the end side of the fence beam 9 with the extension plate 5, the fence beam 9 is less likely to be exposed. This further improves the compatibility of the post mounting structure 100. Here, the insertion direction of the fence beam 9 is the first horizontal direction X in Figures 1(a) and 1(b).

[0042] The extension plate portion 5 is continuous with the pair of side plate portions 3 (side plate portion 31, side plate portion 32) and the locking portion 23, as shown in, for example, FIGS. 2(a) and 2(b).

[0043] (Support mounting structure 100) Next, a pole mounting structure 100 using the reinforcing metal fitting 1 will be described with reference to the drawings.

[0044] As shown in Figures 3(a) and 3(b), for example, the pole mounting structure 100 comprises a pole 7 erected in the vertical direction Z, a pole mounting bracket 8 attached to the pole 7 and having an opening at the top, a fence beam 9 whose end is inserted into the pole mounting bracket 8, and a reinforcing bracket 1 fastened to the pole mounting bracket 8 via a screw fastener B9. Figure 3(b) is a partially enlarged view of the upper part of the reinforcing bracket 1 in Figure 3(a). As shown in Figure 3(b), for example, when viewed in the fastening direction of the screw fastener B9, the side opposite the pole 7 from the fastening axis is defined as a separation region R1, and the side of the fastening axis toward the pole 7 is defined as a proximity region R2.

[0045] In the post mounting structure 100, for example, at least the upper plate 2 is provided in the separation region R1. In this case, when a load is applied vertically downward (downward in the vertical direction Z) to the fence beam 9, the upper plate 2 is locked onto the upper surface of the fence beam 9, preventing the post mounting bracket 8 from moving in a direction that would cause it to bend relative to the fence beam 9 around the screw fastener B9. This improves the compatibility and safety of the post mounting structure 100.

[0046] The post mounting structure 100 may further include an upper plate 2 in the adjacent region R2, for example. In this case, when a vertically downward load is applied to the fence beam 9, the upper plate 2 is more securely locked onto the upper surface of the fence beam 9, further preventing the post mounting bracket 8 from moving in a bending direction relative to the fence beam 9 around the screw fastener B9. This improves the compatibility and safety of the post mounting structure 100. Furthermore, if the upper plate 2 covers the upper surface of the end of the fence beam 9, the fence beam 9 is less likely to be exposed. This further improves the compatibility of the post mounting structure 100.

[0047] The positional relationship between the reinforcing bracket 1 and the pole mounting bracket 8 that constitute the pole mounting structure 100 is as shown in Figure 4. Figure 4 is a cross-sectional view showing the CC cross section of Figure 3(a), which shows the pole mounting structure 100 as viewed from the side.

[0048] In the pole mounting structure 100, for example, in the CC cross section, the upper plate portion 2 can come into contact with the upper end 8u of the pole mounting bracket 8. In the pole mounting structure 100, the pair of side plate portions 3 may be arranged on the outer peripheral surfaces of the pair of side plates 8s of the pole mounting bracket 8, or on the inner peripheral surfaces of the pair of side plates 8s, as shown in FIG.

[0049] In the post mounting structure 100, for example, at the CC cross section, the locking portion 23 of the reinforcing bracket 1 and the upper end 8u of the post mounting bracket 8 are always in contact. In this case, the upper plate portion 2 is more securely locked to the upper end 8u of the post mounting bracket 8 via the locking portion 23, in addition to the upper surface of the fence beam 9, further preventing the post mounting bracket 8 from moving in a bending direction relative to the fence beam 9 around the screw fastener B9. This further improves the compatibility and safety of the post mounting structure 100.

[0050] In the pole mounting structure 100, for example, in the CC cross section, the end side of the fence beam 9 is covered with the extension plate portion 5. In this case, the fence beam 9 is difficult to see from the outside. This further improves the compatibility of the pole mounting structure 100.

[0051] The post mounting structure 100 may fasten the reinforcing bracket 1, post mounting bracket 8, and fence beam 9 together using a single screw fastener B9 inserted through a pair of holes 4 (holes 41 and 42) in the reinforcing bracket 1, holes 81 and 82 respectively drilled in a pair of side plates 8s of the post mounting bracket 8, and holes 91 and 92 respectively drilled in the side surface (cylindrical surface) of the fence beam 9. In this case, the number of fastening parts is reduced compared to when the reinforcing bracket 1 is fastened only to the post mounting bracket 8. This improves the ease of installation of the post mounting structure 100.

[0052] The pole mounting structure 100 may be configured, for example, as shown in FIG. 5, by a rail beam 9 having a cylindrical shape, or by a rail beam 9 having a bottom 9d including a groove (vertical lattice) that opens downward.

[0053] <Strut 7> The support poles 7 are erected in the vertical direction Z. For the support poles 7, for example, known steel support poles that constitute pedestrian and bicycle fences are used.

[0054] The support pole 7 is fastened to the support pole mounting bracket 8 via, for example, a screw fastener B7. The screw fastener B7 is, for example, a known combination of a bolt and a nut.

[0055] <Support mounting bracket 8> The pole mounting bracket 8 is attached to the pole 7 and has an opening at the top. A known bracket such as that disclosed in JP 2015-187370 A (Patent Bracket for Mounting Fence Beams) can be used as the pole mounting bracket 8. The pole mounting bracket 8 is made of, for example, steel.

[0056] 4, the pole mounting bracket 8 has a generally U-shaped cross section and includes a bottom plate 8d and a pair of side plates 8s. The pole mounting bracket 8 contacts a part of the reinforcing bracket 1, for example, at upper ends 8u which are the ends of the pair of side plates 8s. The pair of side plates 8s of the pole mounting bracket 8 may be spaced apart from or in contact with the pair of side plate portions 3 (side plate portions 31, 32) of the reinforcing bracket 1.

[0057] The pole mounting bracket 8 has, for example, a drilled hole 81 and a drilled hole 82 drilled in each of a pair of side plates 8s. Screw fasteners B9 for fastening the pole mounting bracket 8 and the reinforcing bracket 1 are inserted into the drilled holes 81 and 82. The drilled holes 81 and 82 are opposed to and spaced apart from each other on the fastening axis of one screw fastener B9, for example.

[0058] The column mounting bracket 8 is fastened to the reinforcing bracket 1 via, for example, a screw fastener B9. The screw fastener B9 has, for example, a bolt B91 and a nut B92. The screw fastener B9 is, for example, a known combination of a bolt and a nut.

[0059] <Fence Beam 9> The ends of the fence beam 9 are inserted into the support mounting bracket 8. The fence beam 9 is made of, for example, a known steel beam pipe that constitutes a pedestrian and bicycle fence.

[0060] The fence beam 9 has holes 91 and 92 drilled, for example, on its side. Screw fasteners B9 are inserted through holes 91 and 92 to fasten the fence beam 9 to the post mounting bracket 8. Holes 91 and 92 are spaced apart and opposite each other, for example, on the fastening axis of one screw fastener B9.

[0061] The fence beam 9 is fastened to the support bracket 8 via, for example, a screw fastener B9. The fence beam 9 may also be fastened to the reinforcing bracket 1 via, for example, a screw fastener B9.

[0062] The fence beam 9 may be cylindrical, for example, as shown in FIG. 4, or may be shaped to have a bottom 9d including a groove (grating) that opens downward, as shown in FIG.

[0063] (Method for constructing the support mounting structure 100) Next, an example of a method for constructing the pole mounting structure 100 in this embodiment will be described with reference to the drawings.

[0064] First, as shown in Figures 6(a) to 6(c), for example, a pole mounting bracket 8 is attached to a pole 7 that has been set up in advance along the vertical direction Z via a screw fastener B7. Note that Figure 6(b) is a schematic plan view of Figure 6(a), and Figure 6(c) is a schematic cross-sectional view showing the DD cross section of Figure 6(a). At this time, the pole mounting bracket 8 is set up to protrude in the first horizontal direction X from the pole 7, for example.

[0065] After that, the end of the fence beam 9 is inserted into the internal space Q' of the support post mounting bracket 8. At this time, the fence beam 9 is in a temporary state, placed in contact with the bottom plate 8d of the support post mounting bracket 8. In the example of Figure 6(a), the fence beam 9 is temporarily attached to the support post mounting bracket 8 so that it is parallel to the first horizontal direction X.

[0066] In addition, because the post mounting bracket 8 has an opening at the top, the fence beam 9 can swing freely up and down (in a plane perpendicular to the second horizontal direction Y) around its end as an axis when it is temporarily installed. This allows the fence beam 9 to be temporarily placed on the post mounting bracket 8 at an angle with respect to the first horizontal direction X, for example, to match the gradient of the road on which the post 7 is to be installed.

[0067] Next, as shown in Figures 7(a) and 7(b), for example, the reinforcing bracket 1 is fitted to the post mounting bracket 8 so that it covers the top of the post mounting bracket 8 and the fence beam 9 and so that the locking portion 23 contacts the upper end 8u of the post mounting bracket 8. Note that Figure 7(b) is a schematic cross-sectional view showing the E-E cross section of Figure 7(a). At this time, the reinforcing bracket 1 is positioned so that one screw fastener B9 (bolt B91) can be inserted through drilled holes 41 and 42 pre-drilled in the reinforcing bracket 1, drilled holes 81 and 82 pre-drilled in the post mounting bracket 8, and drilled holes 91 and 92 pre-drilled in the fence beam 9.

[0068] Thereafter, the bolt B91 is inserted through the bore 41, bore 42, bore 81, bore 82, bore 91, and bore 92, and then engaged with the nut B92 to be fastened.

[0069] Through the above steps, the pole mounting structure 100 is constructed.

[0070] According to this embodiment, the reinforcing bracket 1 covers the opening above the post mounting bracket 8 and is equipped with at least an upper plate portion 2 that is provided on the opposite side of the fastening axis from the post 7 (separate region R1) when viewed in the fastening direction of the screw fastener B9. As a result, when a vertically downward load is applied to the fence beam 9, the upper plate portion 2 is engaged with the top surface of the fence beam 9, preventing the post mounting bracket 8 from moving in a direction that would cause it to bend relative to the fence beam 9, with the screw fastener B9 as the axis. This improves the compatibility and safety of the post mounting structure 100.

[0071] Furthermore, according to this embodiment, the upper plate portion 2 is located further toward the post 7 than the fastening axis (proximal region R2) when viewed in the fastening direction. Therefore, when a vertically downward load is applied to the fence beam 9, the upper plate portion 2 is more securely locked onto the upper surface of the fence beam 9, making it easier to prevent the post mounting bracket 8 from moving in a bending direction relative to the fence beam 9 around the screw fastener B9. This further improves the compatibility and safety of the post mounting structure 100. Furthermore, when the upper plate portion 2 covers the upper surface of the end of the fence beam 9, the fence beam 9 is less likely to be exposed. This further improves the compatibility of the post mounting structure 100.

[0072] Furthermore, according to this embodiment, the upper plate 2 is always in contact with the upper end 8u of the post mounting bracket 8 on the side of the post 7 closer to the fastening axis (proximal region R2) when viewed in the fastening direction. This allows the upper plate 2 to be more securely fastened to the upper end 8u of the post mounting bracket 8 via the locking portion 23, in addition to the top surface of the fence beam 9, further preventing the post mounting bracket 8 from moving in a direction bending relative to the fence beam 9 around the screw fastener B9 as an axis. Furthermore, vertically downward loads applied to the fence beam 9 are distributed by being transmitted via the screw fastener B9 and the locking portion 23. This further improves the compatibility and safety of the post mounting structure 100.

[0073] Furthermore, according to this embodiment, an extension plate 5 is further provided that extends downward from the upper plate 2, on the insertion direction of the fence beam 9 and on the side of the post 7 relative to the fastening axis when viewed in the fastening direction (proximal region R2). Therefore, by covering the end side of the fence beam 9 with the extension plate 5, the fence beam 9 is less likely to be exposed. This further improves the compatibility of the post mounting structure 100.

[0074] Furthermore, according to this embodiment, the post mounting structure 100 is equipped with at least an upper plate 2 that covers the opening above the post mounting bracket 8 and is provided on the opposite side of the fastening axis from the post 7 (separate region R1) when viewed in the fastening direction of the screw fastener B9. As a result, when a vertically downward load is applied to the fence beam 9, the upper plate 2 is locked onto the top surface of the fence beam 9, preventing the post mounting bracket 8 from moving in a direction that would cause it to bend relative to the fence beam 9 around the screw fastener B9. This improves the compatibility and safety of the post mounting structure 100.
