Description

Technical Field

[0001] The present invention relates to a handrail with a coping, which includes a support column for supporting a handrail body and a coping.

Background Art

[0002] In a veranda or balcony of a building, etc., a handrail with a coping may be installed at a handrail installation part (for example, the upper surface part of a waist wall). In the handrail with a coping, the coping covers the handrail installation part, and a support column is attached to a support column reinforcing member protruding from the coping. Conventionally, a handrail with a coping device for closing a gap between an insertion opening of the coping and a support part with a sealing material is known (see Patent Document 1) under the support part of the support column part.

[0003] In the conventional handrail with a coping device described in Patent Document 1, the support part is a support column reinforcing member that inserts through an insertion opening of the coping, and supports the support column part via a connecting member. Also, a portion between the coping and the support column part is waterproofed with a sealing material. However, in the conventional handrail with a coping device, the work for waterproofing with a sealing material including the application of the sealing material may require time and labor. For example, it is necessary to perform masking work with masking tape or the like so as not to stain portions other than the portion where the sealing material is applied, and it also takes time for the sealing material to dry. There is also a risk that the waterproof property of the coping depends on the skill of the operator by manually applying the sealing material.

Mode for Carrying Out the Invention

[0009] An embodiment of the handrail with coping of the present invention will be described with reference to the drawings. The handrail with coping of the present embodiment (hereinafter referred to as the handrail) is a handrail structure with a coping and is installed at the handrail installation part. The handrail installation part is a place (installation target part) where the handrail is installed in the handrail installation target (for example, a building, a structure). Hereinafter, taking the handrail installed on the veranda of a building as an example, the handrail of the present embodiment will be described.

[0010] FIG. 1 is a front view showing the handrail 1 of the present embodiment, showing the handrail 1 as seen from the outdoor side. FIG. 2 is a longitudinal sectional view showing the handrail 1 of the present embodiment cut along the X1-X1 line in FIG. 1, and FIG. 3 is a cross-sectional view showing the handrail 1 of the present embodiment cut along the X2-X2 line in FIG. 1. As shown in the figure, the handrail 1 is attached to the upper surface of the convex part which is the installation surface 2A of the handrail installation part 2, and is installed in a state where it stands on the handrail installation part 2. The handrail installation part 2 is a convex part (for example, a wall, a rising part) of the veranda of the building and extends in the left - right direction. In the handrail installation part 2, with the handrail 1 as a boundary, the locations (spaces) on one side and the other side of the handrail 1 are partitioned by the handrail 1. The handrail 1 protrudes upward in the handrail installation part 2 and stands between the indoor space and the outdoor space.

[0011] When the handrail 1 installed on the handrail installation part 2 is viewed from the front (see Fig. 1), the up - down direction is the vertical direction, and the left - right direction is the horizontal direction. In Fig. 1, the up - down direction is the vertical direction, and the left - right direction is the horizontal direction. The indoor - outdoor direction is the indoor - outdoor direction of the handrail 1 installed on the handrail installation part 2. Also, the indoor - outdoor direction is the front - back direction (depth direction) when the handrail 1 installed on the handrail installation part 2 is viewed from the front, and in Fig. 1, it is the horizontal direction orthogonal to the left - right direction. Thus, the directions related to the handrail 1 are specified in the state of being installed on the handrail installation part 2. Also, regarding the handrail 1, the indoor side and the outdoor side are the indoor side and the outdoor side in the indoor - outdoor direction in the state of being installed on the handrail installation part 2.

[0012] The handrail 1 includes a plurality of columnar supports 3 extending in the up - down direction, a lattice body 4 provided between adjacent supports 3, a handrail body 5 supported by the supports 3, a support reinforcing member 10 arranged inside each of the plurality of supports 3, a coping 20 covering the handrail installation part 2 from above, and a plurality of coping holders 6 for holding the coping 20. The plurality of supports 3 are arranged at intervals in the left - right direction in the handrail installation part 2 and each protrudes upward from the coping 20. The handrail body 5 is a handrail coping extending in the left - right direction, spanning across the plurality of supports 3 and attached to the supports 3. The support reinforcing member 10 (in Fig. 2, the support reinforcing member 10 inside the support 3 is shown by a dashed line) is attached to the handrail installation part 2, protrudes upward from the coping 20, and is inserted into the support 3.

[0013] The support post 3 is attached to the support post reinforcement member 10 by connecting screws 30 (connecting screws), which are connectors, at multiple points in the vertical direction (longitudinal direction of the support post 3) above the cap rail 20. The support post reinforcement member 10 is a support member that supports and reinforces the support post 3. The cap rail 20 is a plate-shaped covering material that is positioned above the handrail installation section 2 and extends horizontally along the handrail installation section 2. Multiple cap rail holders 6 are positioned at intervals in the horizontal direction and each is attached to the handrail installation section 2. The cap rail 20 is connected to and held in the handrail installation section 2 by the cap rail holders 6. The cap rail 20 is positioned above the handrail installation section 2, forming a space 7 between it and the handrail installation section 2. In this state, the cap rail holders 6 suppress downward bending of the cap rail 20.

[0014] The space 7 is a space (lower space) formed below the coping 20, and is partitioned between the coping 20 and the handrail installation area 2 by the coping 20. The support column reinforcement member 10 is attached to the handrail installation area 2 inside the space 7 below the coping 20 by a plurality of screws 31 (mounting screws), which are mounting fixtures. The support column reinforcement member 10 also protrudes upward from the coping 20 and is positioned inside the support column 3 outside the space 7 above the coping 20, and is connected to the support column 3 by screws 30. The support column 3 is attached to the support column reinforcement member 10 that protrudes from the coping 20 above the coping 20 by screws 30.

[0015] Figure 4 is a vertical cross-sectional view showing the lower portion of the handrail 1 in this embodiment, with the screws 31 omitted and showing an enlarged portion of Figure 2. Figure 5 is a vertical cross-sectional view showing a disassembled portion of the handrail 1 in this embodiment. As shown in the figure, the support column reinforcement member 10 has a plate-shaped base 11 (base plate) and a plate-shaped connecting column 12 fixed to the base 11. The base 11 of the support column reinforcement member 10 is placed on the handrail installation part 2 (installation surface 2A) below the cap rail 20 and positioned inside the space 7 between the handrail installation part 2 and the cap rail 20, and is attached to the handrail installation part 2 by screws 31. In this way, the support column reinforcement member 10 is fixed to the handrail installation part 2. The connecting column 12 of the support column reinforcement member 10 is a columnar connecting part that protrudes upward from the base 11.

[0016] The coping 20 has a plate-shaped covering portion 21 that covers the handrail installation portion 2 from above, and insertion portions 22 formed in the covering portion 21. The covering portion 21 of the coping 20 is the upper surface portion (upper plate) of the coping 20 positioned above the handrail installation portion 2, and faces the handrail installation portion 2 in the vertical direction. The insertion portions 22 are holes (insertion holes) that penetrate the covering portion 21 of the coping 20 in the vertical direction, and are formed at multiple locations on the covering portion 21 at sequential intervals in the left-right direction (longitudinal direction of the coping 20). The support column reinforcement member 10 is inserted through the insertion portions 22 of the coping 20 and protrudes from the coping 20 and the insertion portions 22, and the support column 3 is attached to the support column reinforcement member 10 that protrudes from the coping 20 and the insertion portions 22.

[0017] Specifically, the insertion portion 22 of the coping 20 is positioned above the base portion 11 of the support column reinforcement 10. The support column reinforcement 10 (in this case, the connecting column 12) is inserted vertically through the insertion portion 22 of the coping 20 from inside the space 7 toward the outside of the space 7 (above the coping 20 and the insertion portion 22), and protrudes upward from the coping 20 and the insertion portion 22 outside the space 7. The connecting column 12 of the support column reinforcement 10 is inserted into the support column 3 from below and positioned inside the support column 3. The support column 3 surrounds the connecting column 12 of the support column reinforcement 10 and is positioned around the connecting column 12, and is attached to the connecting column 12. In this state, the support column 3 is connected to the connecting column 12 of the support column reinforcement 10 and attached to the connecting column 12 and the support column reinforcement 10.

[0018] The handrail 1 comprises an annular drainage component 40 positioned on the upper side (outside the space 7) of the coping 20 (here, the covering portion 21), and an annular coping support body 50 positioned on the lower side (inside the space 7) of the coping 20. The drainage component 40 and the coping support body 50 each have insertion portions 41, 51 through which the connecting column 12 of the support reinforcing member 10 is inserted. The insertion portion 41 of the drainage component 40 is a hole (insertion hole) that penetrates the drainage component 40 in the vertical direction, and the insertion portion 51 of the coping support body 50 is a hole (insertion hole) that penetrates the coping support body 50 in the vertical direction. The drainage component 40 is positioned on the upper side of the coping 20, resting on the coping 20, and above the insertion portion 22 of the coping 20. The coping support 50 is placed on the lower side of the coping 20, on the support reinforcement 10 (in this case, the base 11), and positioned below the insertion portion 22 of the coping 20.

[0019] Below the coping 20 (inside the space 7), the connecting column 12 of the support reinforcement member 10 is inserted vertically through the insertion portion 51 of the coping support body 50, and the coping support body 50 is positioned around the connecting column 12, surrounding the connecting column 12 of the support reinforcement member 10. The coping support body 50 is positioned between the base 11 of the support reinforcement member 10 and the coping 20, and is sandwiched between the base 11 of the support reinforcement member 10 and the coping 20 to support the coping 20. The coping 20 is supported from below by the coping support body 50. In addition, at the locations of the support reinforcement member 10 and the support column 3, the coping support body 50 ensures the distance between the base 11 of the support reinforcement member 10 and the coping 20, and the space 7 below the coping 20.

[0020] Above the coping 20 (outside the space 7), the connecting column 12 of the support reinforcement member 10 protrudes from the coping 20 and passes through the insertion portion 41 of the drainage component 40 in the vertical direction. The drainage component 40 is arranged around the connecting column 12 of the support reinforcement member 10 that protrudes from the coping 20. The connecting column 12 of the support reinforcement member 10 passes through the insertion portion 51 of the coping support body 50, the insertion portion 22 of the coping 20, and the insertion portion 41 of the drainage component 40 in order from bottom to top, and protrudes upward from the drainage component 40 and the insertion portion 41. The support column 3 is placed on the drainage component 40 and attached to the connecting column 12 of the support reinforcement member 10 that protrudes from the drainage component 40 and the insertion portion 41.

[0021] The drainage component 40 is positioned between the support column 3 and the coping 20 (here, between the lower end of the support column 3 and the covering portion 21 of the coping 20), and is sandwiched between the support column 3 and the coping 20, supporting the support column 3. When water enters the inside of the support column 3, the drainage component 40 receives the water at the bottom inside the support column 3 and drains the water toward the outside of the support column 3. Inside the support column 3, the water enters between the connecting column 12 of the support column reinforcement member 10 inside the support column 3 and the support column 3, and falls down to the drainage component 40. Subsequently, the water is drained by the drainage component 40 toward the outside of the support column 3, towards the indoor side of the drainage component 40.

[0022] Figure 6 is a plan view showing the drainage component 40 placed on the coping 20 of this embodiment, viewed from above. In Figure 6, the cross-section of the support column 3 is shown by a dashed line, and the cross-section of the connecting column 12 of the support column reinforcement member 10 is shown by a dotted line. Figure 7 is a perspective view showing the drainage component 40 of this embodiment, showing the drainage component 40 viewed from diagonally above on the indoor side. As shown in the figure, the drainage component 40 has, in addition to the insertion portion 41, an upper portion 42 located on the upper side (support column 3 side), a lower portion 43 located on the lower side (coping 20 side), and a drainage portion 44 formed on the lower portion 43.

[0023] The support column 3 rests on the upper surface 42 of the drainage component 40, and the upper surface 42 receives water that enters the interior of the support column 3. The lower surface 43 of the drainage component 40 rests on the coping 20. The inner circumference 45 of the insertion portion 41 is the inner circumference of the drainage component 40, and the insertion portion 41 penetrates the drainage component 40 from the upper surface 42 to the lower surface 43. With the connecting column 12 of the support column reinforcement member 10 inserted through the insertion portion 41, the inner circumference 45 of the insertion portion 41 is positioned with a gap between it and the connecting column 12 of the support column reinforcement member 10, and the insertion portion 41, by its inner circumference 45, forms a gap 46 between it and the connecting column 12 of the support column reinforcement member 10. The gap 46 is a drainage gap through which water flows, and drains water that enters the interior of the support column 3 downwards.

[0024] The gap 46 is formed along the outer surface of the connecting column 12 of the support column reinforcement member 10, surrounding the connecting column 12 and located around it. The gap 46 is located in the lower part of the interior of the support column 3 and is open upward and downward. The drainage section 44 of the drainage component 40 is a drainage channel formed in a concave shape on the lower surface 43 and is located below the upper surface 42. The drainage section 44 is located on the indoor side of the insertion section 41 and the gap 46 of the drainage component 40, and is formed from the insertion section 41 to the indoor end face of the drainage component 40. The drainage section 44 is open toward the insertion section 41 and the gap 46, connecting to the insertion section 41 and the gap 46, and is also open toward the outside (indoor side) of the drainage component 40.

[0025] Water that enters the interior of the support column 3 flows into the gap 46, passes through the gap 46, and is drained towards the lower coping 20 and the drainage section 44 of the drainage component 40. The water that has passed through the gap 46 reaches the drainage section 44, and the drainage section 44 drains the water from the drainage component 40 to the outside (indoor side) of the drainage component 40. In this way, the water is drained from the interior of the support column 3 to the exterior of the support column 3. Also, on the indoor side of the drainage component 40, the water flows towards the indoor side over the covering 21 of the coping 20.

[0026] The coping support body 50 (see Figures 4 and 5) has an annular elastic material 60 that contacts the coping 20 and the connecting column 12 of the support reinforcement member 10, and an annular spacer 70 that supports the elastic material 60. The elastic material 60 and the spacer 70 are bonded to each other by double-sided tape provided between them. Insertion portions 51 of the coping support body 50 are formed on both the elastic material 60 and the spacer 70. The spacer 70 is located on the base 11 side and the handrail installation portion 2 side (lower side) of the support reinforcement member 10 in the coping support body 50, and is placed on the base 11 of the support reinforcement member 10 from above. The spacer 70 is also positioned between the base 11 of the support reinforcement member 10 and the elastic material 60. The elastic material 60 is located on the coping 20 side (upper side) in the coping support body 50, and is positioned between the coping 20 (covering portion 21) and the spacer 70 while resting on the spacer 70.

[0027] Figure 8 is a plan view showing the coping support 50 of this embodiment as seen from above. Figure 9 is a perspective view showing the coping support 50 of this embodiment, and Figure 10 is a perspective view showing the coping support 50 of this embodiment in an exploded view. Figure 11 is a longitudinal cross-sectional view showing the coping support 50 of this embodiment cut along the line X3-X3 in Figure 8. As shown in the figure, the elastic material 60 and spacer 70 of the coping support 50 are separate parts, and the elastic material 60 is placed on top of the spacer 70 from above. The elastic material 60 is the elastically deformable part (soft part) of the coping support 50, which is softer than the spacer 70, and has lower rigidity against deformation than the spacer 70. The spacer 70 is the base part (hard part) of the coping support 50, which is harder than the elastic material 60, and has higher rigidity against deformation than the elastic material 60.

[0028] The elastic material 60 of the coping support 50 is an elastically deformable waterproofing material (elastic waterproofing material) and is made of sponge (for example, silicone sponge, which is a sponge-like silicone rubber). The spacer 70 of the coping support 50 is a resin component (hard resin component) and is a receiving portion that receives the elastic material 60 on the lower side of the elastic material 60. The insertion portion 51 of the coping support 50 consists of an insertion portion 61 formed in the elastic material 60 and an insertion portion 71 formed in the spacer 70. The connecting column 12 of the support column reinforcement 10 is inserted through the insertion portion 71 of the spacer 70 and the insertion portion 61 of the elastic material 60, respectively.

[0029] The spacer 70 has an annular outer circumference 72, an annular inner circumference 73 that surrounds the connecting column 12 of the support reinforcement member 10, and an annular receiving surface 74 that receives the elastic material 60. The inner circumference 73 of the spacer 70 is located on the inner circumference of the insertion portion 71 of the spacer 70 and is positioned around the connecting column 12 of the support reinforcement member 10, either with a gap between it and the connecting column 12 or in contact with the connecting column 12 of the support reinforcement member 10.

[0030] The receiving surface 74 of the spacer 70 faces the coping 20 in the vertical direction, with the elastic material 60 in between. Furthermore, the receiving surface 74 of the spacer 70 is the upper surface (inclined surface) of the spacer 70 which is inclined with respect to the horizontal plane, and has a gradient that gradually slopes downward from the outer circumference 72 toward the inner circumference 73 (connecting column 12 of the support reinforcing material 10) away from the coping 20 with respect to the horizontal plane.

[0031] The elastic material 60 has an annular outer circumference 62, an annular inner circumference 63 that surrounds the connecting column 12 of the support reinforcement material 10, an annular mounting surface 64 that rests on the receiving surface 74 of the spacer 70, and an annular pressing surface 65 that is pressed by the coping 20. The inner circumference 63 of the elastic material 60 is located on the inner circumference of the insertion portion 61 of the elastic material 60, and is in contact with the connecting column 12 of the support reinforcement material 10, and is positioned around the connecting column 12. The mounting surface 64 of the elastic material 60 is the lower surface of the elastic material 60 and faces the receiving surface 74 of the spacer 70. The pressing surface 65 of the elastic material 60 is the upper surface of the elastic material 60 and is in contact with the lower surface of the coping 20 (covering portion 21).

[0032] The elastic material 60 (mounting surface 64) is placed on the receiving surface 74 of the spacer 70 from above. In this state, the elastic material 60 deforms in accordance with the slope (inclination) of the receiving surface 74 of the spacer 70 and is positioned along the receiving surface 74 (see Figure 11). As a result, the mounting surface 64 and pressing surface 65 of the elastic material 60, like the receiving surface 74 of the spacer 70, gradually incline with respect to the horizontal plane from the outer circumference 62 to the inner circumference 63 in a direction away from the coping 20. In addition, the receiving surface 74 of the spacer 70, and the mounting surface 64 and pressing surface 65 of the elastic material 60, incline diagonally downward toward their respective inner circumferences 73, 63. The inner circumference 63 of the elastic material 60 deforms toward the inside side of the insertion portion 61 of the elastic material 60 (the connecting column 12 side of the support reinforcement member 10) and protrudes toward the inside side of the insertion portion 61 of the elastic material 60.

[0033] Figures 12 and 13 are longitudinal cross-sectional views showing the column reinforcement member 10, the coping 20, and the coping support body 50 of this embodiment. The shapes of the column reinforcement member 10, the coping 20, and the coping support body 50 are simplified, and they are schematically shown. Figure 12 shows the state before the coping 20 is supported by the coping support body 50, and Figure 13 shows the state after the coping 20 is supported by the coping support body 50.

[0034] As shown in the figure, the connecting column 12 of the support reinforcement member 10 is inserted through the insertion portion 51 of the coping support body 50 (insertion portion 71 of the spacer 70, insertion portion 61 of the elastic material 60), and the spacer 70 of the coping support body 50 is placed on the base portion 11 of the support reinforcement member 10 (see Figure 12). The receiving surface 74 of the spacer 70 is formed such that the distance from the coping 20 gradually widens toward the inner circumference 73 of the spacer 70, and the spacer 70 gradually moves away from the coping 20 toward the inner circumference 73. The elastic material 60 deforms along the receiving surface 74 of the spacer 70, and the inner circumference 63 of the elastic material 60 is pressed against the connecting column 12 of the support reinforcement member 10 and adheres tightly to it.

[0035] Next, the connecting column 12 of the support reinforcement member 10 is inserted into the insertion portion 22 of the coping 20, and the coping 20 is placed on the pressing surface 65 of the elastic material 60 (see Figure 13). The elastic material 60 is pressed by the coping 20 toward the spacer 70 below and undergoes elastic deformation. The elastic material 60, while elastically deformed and sandwiched between the coping 20 and the spacer 70, is in close contact with the coping 20 and the support reinforcement member 10 (in this case, the connecting column 12). Specifically, the coping 20 presses against the pressing surface 65 of the elastic material 60, causing the pressing surface 65 and the elastic material 60 to undergo elastic deformation. The elastic material 60 also undergoes elastic deformation while sandwiched between the coping 20 (the lower surface of the covering portion 21) and the receiving surface 74 of the spacer 70.

[0036] In its elastically deformed state, the elastic material 60 (mounting surface 64) is pressed against the receiving surface 74 of the spacer 70 and adheres tightly. The elastic material 60 (pressing surface 65) is pressed against the surface of the coping 20 on the side of the space 7 (handrail installation area 2 side) (the lower surface of the covering part 21) and adheres tightly. The elastic material 60 (inner circumference 63) is pressed against the connecting column 12 (outer circumference) of the support column reinforcement 10 and adheres tightly. By adhering tightly to the coping 20, the elastic material 60 seals the area between the coping 20 and the elastic material 60, and by adhering tightly to the connecting column 12 of the support column reinforcement 10, it seals the area between the connecting column 12 of the support column reinforcement 10 and the elastic material 60. As a result, the elastic material 60 seals the area between the coping 20 and the connecting column 12 of the support column reinforcement 10 (the insertion part 22 of the coping 20).

[0037] The elastic material 60, while elastically deformed between the coping 20 and the spacer 70, elastically deforms toward the interior of the insertion portion 22 of the coping 20. As a result, the elastic material 60 is pushed into the interior of the insertion portion 22 located around the connecting column 12 of the support reinforcement member 10, and is positioned within the insertion portion 22 of the coping 20. The insertion portion 22 of the coping 20 where the elastic material 60 is positioned is the insertion portion 22 between the connecting column 12 of the support reinforcement member 10 and the inner circumference of the insertion portion 22. Within the insertion portion 22 of the coping 20, the elastic material 60 surrounds the connecting column 12 of the support reinforcement member 10 and is positioned around the connecting column 12. In addition, the elastic material 60 adheres tightly to the connecting column 12 (outer circumference) of the support reinforcement member 10 and the coping 20 (inner circumference of the insertion portion 22), filling the insertion portion 22. In this way, the elastically deformed elastic material 60 seals the insertion portion 22 around the connecting column 12 of the support reinforcement member 10, thereby preventing water from entering.

[0038] In the handrail 1 described above, the elastic material 60 makes it easy to stop water from entering the area between the coping 20 and the support reinforcement 10, thereby ensuring the watertightness of the coping 20. Furthermore, it reduces the time and effort required for watertight sealing the area between the coping 20 and the support reinforcement 10, improving work efficiency. The elastic material 60 ensures that the watertightness of the coping 20 is maintained stably, and it also prevents water from entering the space 7 below the coping 20 through the insertion part 22 of the coping 20.

[0039] The receiving surface 74 of the spacer 70 presses the elastic material 60 against the connecting column 12 of the support reinforcement member 10, preventing gaps from forming between the elastic material 60 and the connecting column 12 of the support reinforcement member 10. This ensures that the elastic material 60 is securely in contact with the connecting column 12 of the support reinforcement member 10, improving the watertightness between the connecting column 12 of the support reinforcement member 10 and the elastic material 60. The elastic material 60 also seals the insertion portion 22 of the coping 20 around the connecting column 12 of the support reinforcement member 10, preventing water from entering the space 7 below the coping 20 from the insertion portion 22, further improving the watertightness of the coping 20.

[0040] The spacer 70, which is harder than the elastic material 60, can stably support the elastic material 60 and the coping 20. Furthermore, the elastic material 60 can be reliably elastically deformed between the coping 20 and the spacer 70, ensuring that the elastic material 60 is securely in contact with the coping 20 and the connecting column 12 of the support reinforcement 10. The drainage component 40 smoothly drains water that has entered the inside of the support column 3 to the outside, preventing water from accumulating inside the support column 3. Water can be guided and drained to the outside of the support column 3 through the insertion portion 41 and drainage portion 44 of the drainage component 40.

[0041] The elastic material 60 and spacer 70 of the coping support 50 may be a single integrated part or separate parts. Furthermore, the elastic material 60 may be placed on the spacer 70 without adhesive bonding. The elastic material 60 may be made of an elastically deformable material other than sponge. The spacer 70 may be placed at locations other than the base 11 of the support reinforcement 10 (for example, the handrail installation section 2 located around the base 11), depending on the shape or size of the base 11. The spacer 70 may be a hard component made of a material harder than the elastic material 60. Therefore, the spacer 70 is not limited to being made of resin and may be made of a material other than resin.

[0042] As described above, the handrail with a coping is, A handrail with a capping board that is installed at the handrail installation site, A coping that forms a space between itself and the handrail installation portion and has an insertion portion, A support reinforcing member is attached to the handrail installation section in the aforementioned space, and is inserted through the insertion section and protrudes from the cap rail, A support column attached to the support column reinforcing member that protrudes from the aforementioned coping, A handrail body supported by the aforementioned support column, The aforementioned space surrounds the support column reinforcement member, and includes a coping support body that receives the coping, Equipped with, The aforementioned handrail with a capping support comprises a spacer and an elastic material that, when sandwiched between the capping and the spacer and elastically deformed, adheres tightly to the capping and the support column reinforcement. Therefore, the elastic material can be used to easily seal the gap between the handrail cap and the support reinforcement, ensuring the watertightness of the handrail cap.

[0043] The spacer has an inner circumference surrounding the support reinforcing member, and a receiving surface for receiving the elastic material, which is formed such that the distance between it and the cap rail gradually widens toward the inner circumference. The elastic material is sandwiched between the coping and the receiving surface and undergoes elastic deformation. Therefore, the receiving surface of the spacer presses the elastic material against the support column reinforcement, preventing gaps from forming between the elastic material and the support column reinforcement. This ensures that the elastic material adheres securely to the support column reinforcement, improving watertightness between the support column reinforcement and the elastic material.

[0044] The elastic material is placed within the insertion portion and closes the insertion portion around the support reinforcing member. Therefore, the elastic material prevents water from seeping into the gaps through the insertion points of the coping, thereby improving the watertightness of the coping.

[0045] The spacer is harder than the elastic material. Therefore, the spacer allows the elastic material and the coping to be stably supported. Furthermore, the spacer ensures that the elastic material is reliably elastically deformed between the coping and the spacer, allowing the elastic material to be securely in contact with the coping and the support column reinforcement.

[0046] The aforementioned support column reinforcing member protrudes from the cap rail and is positioned inside the support column. The handrail with a capping is equipped with a drainage component that surrounds the support column reinforcing material protruding from the capping, is positioned between the support column and the capping, and drains water that has entered the inside of the support column toward the outside of the support column. Therefore, the drainage component allows water that has entered the inside of the support column to be smoothly drained to the outside, preventing water from accumulating inside the column.

[0047] The drainage component has an insertion portion that forms a gap between itself and the support column reinforcing material when the support column reinforcing material is inserted through it, allowing water that has entered the inside of the support column to drain downward, and a drainage portion that drains the water that has passed through the gap from the drainage component. Therefore, water can be guided to the outside of the support column through the insertion and drainage sections of the drainage components and drained away. [Explanation of symbols]
