Description

  The present invention relates to a mounting structure for a handrail strut member in which a handrail strut member for supporting a handrail used for stairs is attached to a support surface such as a floor surface or a tread board.

  Conventionally, a handrail support member for supporting a handrail of a staircase is supported on a floor surface or a tread board by the following structure. For example, as shown in Patent Document 1, a bolt is fixedly projected to the lower end of a stair railing column, and a nut is fixed to a position where the railing column of the floor or the tread plate is fixed, and the tread plate is installed and fixed. After the stairs are constructed, bolts are screwed onto the nuts to fix the handrail struts. When fixing the lower end of the handrail support to the floor by inserting the tread plate into the floor, a thin cylindrical column tread where the bolt is fixedly projected at the lower end is formed integrally with the lower end of the exposed portion In the case of an insertion part, this tread board insertion part may be a substantially columnar column support material fitted in a fitting hole formed in the axial direction from the lower surface of the handrail support column. In such a configuration, the handrail post is fixed to the floor or the tread board only with nuts, and the strength against the external force applied to the handrail post is very weak, and a through hole is provided in the tread board so that the handrail post is inserted through it. In the case where the handrail support is fixed to the floor, extra processing is required for the tread board, and the cost is high and the structure is easily complicated.

  As another structure, Patent Document 2 discloses a bottomed cylindrical base portion that is placed and fixed on a step plate in a handrail support member that is interposed between a step plate of a staircase and a handrail and supports the handrail from below. And a metal rod having a fixing screw at the lower end portion that is inserted and arranged in the inner hollow portion of the root portion and is screwed to the step plate through the bottom plate of the root portion, and an upper end portion of the metal rod. It is fixed by screwing the screw part of the lower end part, and is disposed so as to protrude from the upper end of the root part covering the screw part of the tip rod part where the upper end part is joined to the handrail and the metal rod and the tip rod part, A handrail support structure is disclosed in which an outer peripheral surface of a lower end portion is formed of an intermediate sleeve portion that is tightly bonded to an inner peripheral surface of a root portion.

  By adopting such a structure, it is possible to easily change the shape of each of the support columns arranged in series while achieving mass productivity, and it is possible to fix them easily without impairing the aesthetic appearance.

  However, in the structure of Patent Document 2, the root portion is fixed to the end surface of the tread using a support bolt, and the support bolt is attached to form a stair nosing opening where the stair nosing is located. Are attached to a support surface such as a floor surface or a tread board, the height dimension of the tread board at each stage is not necessarily a common dimension, and is often different. In Patent Document 2, different height dimensions are used for different height dimensions. It is necessary to prepare a handrail support column, which tends to be expensive.

  Patent Document 3 discloses a structure in which a handrail support member can be used as a common component even for such different lifting dimensions. In Patent Document 3, a structure is disclosed in which a column base is attached to a floor plate of a staircase or a floor of a lower floor, and a handrail column is erected by attaching a lower end of a rail column on the column base. Yes. A handrail bar placed along the slope of the stairs is attached to and supported by the upper end of the handrail support column. Each handrail post is placed along the nose portion at the front end of the tread plate that is one step higher than the attachment position of the lower end of the handrail post, and the handrail post is fixed to the nose portion of the tread plate so that the vertical position can be adjusted. According to this structure, even if the height between the upper and lower treads changes, the position at which the handrail support column is fixed to the step nose of the treads can be changed, so that various parts can be handled by common members using common parts.

  However, in Patent Document 3, the handrail column is fixed to the nose part of the tread plate so that the vertical position can be adjusted by providing a long hole or a plurality of holes for fixing to the nose part of the tread plate in the handrail column. Therefore, it is necessary to adjust the handrail support vertically enough to fix the fixing tool through which position or through which hole, and the fixing work is troublesome. Moreover, an adjustment hole is provided on the surface facing the fixing hole in the hollow handrail support column, and the fixing tool is inserted into the fixing hole through this adjustment hole to fix it further. Is cumbersome and difficult for beginners. Furthermore, since the area required for the fixing hole is increased, the rigidity of the handrail support column itself is likely to be weak, so that it can withstand the large force applied to the handrail support column when climbing the stairs by hand on the handrail. This is a very serious problem when considering the rigidity.

  In order to solve such a problem, the present invention can easily attach the handrail support member to the front end surface of the stairs, and is common even when the height dimensions of the upper and lower treads, that is, the kick-up dimensions are different. It is an object of the present invention to provide an attachment structure for a handrail strut member that uses a handrail strut member that can be used as a component and has a rigidity that can withstand a large force applied to the handrail.

  In order to solve such a problem, the present inventor maintains strong rigidity without applying extra processing for attaching the handrail support member to the end surface of the tread plate, and positions the handrail support member in the upper stage. It came to invent the attachment structure of the handrail support | pillar member which can be easily attached to the end surface of a tread, without performing the troublesome operation | work of adjusting the vertical position with respect to a tread. Specifically, the following means are provided.

  That is, the present invention is an attachment structure of a handrail strut member using a long bar-shaped handrail strut member in which a lower end portion is fixed to a support surface such as a step board or a floor board of a staircase and a handrail member is attached to the upper end portion. A support body for supporting and fixing the lower end of the handrail strut member is fixed to the support surface, while the handrail strut member having one side abutting against the end surface of the tread plate located on the upper stage is The handrail strut member is attached to the end surface of the tread by an attachment member attached to the end surface of the tread with a side surface facing one side of the handrail strut member pressed against the end surface of the tread.

  According to the invention having such a configuration, the handrail support member whose lower end portion is fixed to the support surface is not directly fixed to the end surface of the tread board by providing a fixing hole or the like to the end surface of the tread board. The handrail strut member is attached to the end surface of the tread plate only by being attached to the end surface of the tread plate in a state where the side surface facing one side surface of the handrail strut member is pressed to the end surface side of the tread plate by the mounting member. It is not necessary to adjust the vertical position with respect to the end surface of the tread board when attaching the member, making the installation work very easy, and it is not necessary to perform processing for attachment to the end surface of the tread board on the handrail support member. In addition to reducing the rigidity of the handrail strut member accompanying this, the cost can be reduced. In addition, depending on the staircase design, the kick-up dimension from the support surface to the upper staircase is not always the same and is generally different, but according to the present invention, it is attached to the end face of the tread regardless of the kick-up dimension. The handrail support member can be used as a common general-purpose member.

  Further, the present invention is the mounting structure of the handrail strut member, wherein the mounting member has a form in which the surface in contact with the handrail strut member follows another side surface other than one side surface of the handrail strut member, Mounting holes are provided at both end portions for attaching to the end face of the tread using a mounting jig, and the other side of the handrail support member is covered with the handrail support member sandwiching the handrail support member. It is attached to the end face.

  According to the present invention, the mounting member has a form following the other side surface other than the one side surface of the handrail support member, and covers the other side surfaces other than the one side surface of the handrail support member. Since the mounting hole is attached to the end surface of the tread using a mounting jig, only the mounting jig is attached to the end surface of the tread to restrict the horizontal movement of the handrail post member and press the handrail post member against the end surface of the tread. And a stable mounting structure can be obtained easily.

  Further, in the present invention, a panel mounting hole for mounting a plate-like panel is provided on one end surface of the handrail support member, and the panel extends over the handrail support member positioned in the upper stage. The panel mounting hole is mounted via a spacer having a thickness dimension larger than the thickness dimension of the mounting member.

  According to the invention having this configuration, the panel attached over the handrail support member positioned in the upper stage is attached to each panel attachment hole via the spacer having a thickness dimension larger than the thickness dimension of the attachment member. Therefore, for example, even when the outer edge shape of the panel is formed in an inclined shape that matches the inclination of the staircase and the panel is attached to the handrail strut member so as to overlap the attachment member, the panel contacts with the thickness of the spacer. Can be avoided, and a good mounting structure can be obtained.

  In addition, since the panel is attached to the handrail support member via the spacer, for example, when a person goes up the stairs using the handrail, even when an external force is applied to the handrail support member, the spacer intervenes. Since the panel and the handrail support member are not in direct contact with each other, it is possible to reduce these squeak noises.

  In the present invention, the panel mounting holes are formed at the edge of the panel, and the spacer has a U-shaped configuration with concave portions sandwiching the front and back surfaces of the panel, and the front and back surfaces of the panel. A through-hole for inserting an attachment means such as a screw for attaching to the handrail support member is formed in a region overlapping the panel attachment hole in the spacer. When an external force is applied to the handrail and the handrail support member bends, additional stress tends to concentrate on the panel mounting holes of the panel attached to the handrail support member with screws, etc. By adopting the configuration, the spacer relaxes the applied stress, so that it is easy to reduce the occurrence of cracks and scratches in the panel mounting holes.

  In the present invention, the diameter of the panel mounting hole is larger than the diameter of the through hole of the spacer. The installation state such as the position and inclination of each tread on the staircase tends to vary, and the installation state of the handrail strut member tends to vary accordingly.Therefore, when the panel is attached to the handrail strut member, the position deviation tends to occur. The mounting hole is formed by making the diameter of the mounting hole larger to absorb the displacement of the handrail support member relative to the panel while the diameter of the spacer that can be freely moved relative to the panel is made smaller. It is possible to improve the mounting state of the.

  Further, the present invention is characterized in that the relationship between the kicking dimension X from the support surface to the tread plate positioned on the upper stage and the tread dimension Y on the support surface is used for a staircase represented by X / Y ≦ 23/15. And

  In the invention having such a configuration, the panel can be attached to the handrail support member without contacting the attachment member by the spacer. Therefore, in order to prevent the possibility of an accident such as a fall as much as possible, it is constructed as a safety standard. As used in the staircase shown in the standard law, “the relationship between the kicking dimension X from the support surface to the upper tread plate and the tread dimension Y on the support surface is X / Y ≦ 23/15”. Is also possible. Further, in the invention having such a configuration, as defined in BL (Better Living), “the kicking dimension from the support surface to the tread plate located on the upper stage is used as a reference that does not make it difficult to go up because the stairs are too low. It is also possible to use the relationship between X and the tread surface dimension Y on the support surface for the staircase represented by “X / Y ≧ 150/195”. In other words, the present invention can be applied to stairs with various inclination angles provided along the above-mentioned respective standards.

  According to the present invention, there is no need to adjust the vertical position with respect to the end surface of the tread board when attaching the handrail support member, the attachment work is greatly facilitated, and the processing for attaching the handrail support member to the end surface of the tread board is facilitated. In addition to not reducing the rigidity of the handrail strut member associated with the processing, it can contribute to low cost, and regardless of the height dimension of the upper and lower treads, that is, the kicking dimension, The handrail support member attached to the end surface of the tread board can be used as a common general-purpose member.

  Next, although one embodiment of the attachment structure of the handrail strut member in the present invention will be described, the present invention is not limited to this.

  FIG. 1 is an explanatory diagram for explaining a mounting structure of a handrail strut member in the present embodiment, and is a schematic side view showing a state in which a handrail is attached to a handrail strut member fixed on a tread board. As shown in FIG. 1, in the handrail support member mounting structure of this embodiment, a round bar-shaped handrail member 1 having a circular cross section, a plurality of handrail support members 2 that support the handrail member 1, and a handrail support member 2. And a flat panel 4 attached to each side surface of two adjacent handrail support members 2 are used. Further, the handrail support member 2 is pressed and supported by the mounting member 6 on the front end surface of the step board 3 positioned in the upper stage. In the present embodiment, the handrail column member 2 has a height dimension of about 100 cm, and is erected with an interval dimension of about 67.4 cm for each of the three steps of the treads 3. Further, the height dimension from the tread board to the upper tread board, that is, the kick-up dimension is about 18 cm, and the tread surface dimension of the tread board is about 23.5 cm. The distance between the handrail member 1 and the panel 4 is about 11.6 cm.

  FIG. 2 is a schematic perspective view showing details of the handrail support member mounting structure in the present embodiment. As shown in FIG. 2, the handrail support member 2 has a lower end portion fixed to the support surface of the step board 3 of the staircase and has a long bar shape in which the handrail member 1 is attached to the upper end portion. Moreover, the handrail support | pillar member 2 is fixed to the tread 3 as a support surface by the L-shaped support | pillar support body (not shown here) for supporting and fixing the lower end part. Further, the handrail support member 2 is in a state where a narrow side surface is in contact with the front end face of the step board 3 that is one step higher than the support surface to which the lower end portion is fixed. 2 is attached to the end surface of the tread plate 3 by an attachment member 6 attached to the end surface of the tread plate 3 in a state where the opposite side surface opposite to the one side surface is pressed to the end surface side of the tread plate 3. The attachment member 6 has a form in which the surface in contact with the handrail support column member 2 follows the other side surface of the handrail support member 2 other than the one side surface. It is attached to the end surface of the tread 3 so as to cover the handrail support member 2. As a result, the handrail support member 2 is mounted in a state where the surface other than the surface in contact with the end surface of the tread 3 is surrounded by the mounting member 6 and pressed against the end surface of the tread 3, so that its horizontal movement is reduced. Straightened and stable mounting structure. Further, a support cover K is provided at the lower end edge of the handrail support member 2 so as to cover the outer peripheral edge portion. Further, a panel 4 is attached to one end surface of the handrail support member 2 via a spacer 8.

  Next, the assembly method regarding the attachment structure of the handrail support | pillar member 2 is demonstrated. FIG. 3 is an exploded view of the mounting structure of the handrail support member 2 shown in FIG. First, the handrail support member 2 is lowered in the vertical direction in a state where one side surface having a narrow width is in contact with the end surface of the step plate 3 of the staircase, and is brought into contact with the step plate 3 as a support surface located at the lower stage. At this time, the position of the support column support 5 is moved so that the handrail support member 2 includes a protruding portion extending upward in the support column support 5. As will be described later, the handrail strut member 2 is in the form of a hollow square pipe, and is erected in a state in which the protruding portion of the strut support 5 is included in the hollow portion. The column support 5 on the floor surface is fixed by being screwed to the floor surface with screws 5b while maintaining one side of the handrail column member 2 in contact with the tread plate 3. The handrail support member 2 has screws 7 inserted through two screw holes 2 a provided at the lower end thereof, and screw holes 5 a formed at predetermined heights in the protruding portion of the support column support 5. By attaching the screw 7, the column support 5 is attached. And the handrail support | pillar member 2 of the state attached to the support | pillar support body 5 and contact | abutted to the end surface of the tread board 3 is attached so that it may press with respect to the end surface of the tread board 3 with the attachment member 6. FIG. The mounting member 6 includes a mounting body 6a provided with mounting holes 6d at both ends thereof for mounting to the end face of the tread plate 3 using screws 6c as mounting jigs, and screws 6c at both ends. And an attachment cover body 6b that covers from the outside. Although not shown, the mounting cover body 6b is fitted so that recesses provided at both ends of the mounting cover body 6b are fitted into return portions formed so as to float to the front side by a predetermined dimension at both ends of the mounting body 6a. To be integrated. Both end portions of the mounting body 6a where the mounting holes 6d are formed are flat so as to come into surface contact with the end surface of the tread board 3. By adopting such a configuration, it is possible to reduce vibrations and squeaks that are generated when a person goes up the stairs or when a hand is applied to the handrail and a force is applied to the handrail support member 2.

  As described above, both ends of the mounting member 6 have a form following the other side surface than the one side surface of the handrail column member 2 so as to cover the other side surface other than the one side surface of the handrail column member 2. Since the attachment hole 6d is attached to the end surface of the tread 3 using screws 6c as an attachment jig, the horizontal movement of the handrail support member 2 is restricted and the handrail support member is only attached to the end surface of the tread plate 3. A stable mounting structure can be easily obtained by pressing 2 against the end face of the tread plate 3. In FIG. 3, the support cover K shown in FIG. 2 is omitted.

  In the handrail support member 2, two screw holes 2a having a predetermined dimension are formed from the lower end, and the panel 4 is attached across adjacent handrail support members (not shown). The strength is improved. Moreover, since the handrail support | pillar member 2 is pierced with the screw hole 2a only in one end surface, the handrail support | pillar support member 2 is turned right and left by the time of attaching the panel 4 to the left side of the handrail support member 2 and the right side. In this case, it can be used as a common member, which can contribute to a reduction in manufacturing cost.

  As described above, the panel 4 is attached to one end surface of the handrail support member 2 via the spacer 8. FIG. 4 is a view showing the spacer 8 of the present embodiment, FIG. 4 (a) is a side view, and FIG. 4 (b) is a front view. As shown in these drawings, the spacer 8 has a U-shaped form in a side view in which a concave portion 8 a that sandwiches both the front and back surfaces of the panel 4 is formed. The thickness dimension of the one side portion 8b across the concave portion 8a is 3 mm, and the thickness dimension is larger than the thickness dimension of the mounting member 6. For this reason, even when the outer edge shape of the panel 4 is formed in an inclined shape corresponding to the inclination of the stairs and the panel 4 is attached to the handrail support member 2 so as to overlap the attachment member 6, the thickness of the spacer 8 is increased. Therefore, it is possible to avoid contact, and it is possible to obtain a good mounting structure. Further, since the panel 4 is attached to the handrail support member 2 via the spacer 8, for example, when a person climbs the stairs using a handrail, an external force is applied to the handrail support member 2 to bend. Since the panel 4 and the handrail support member 2 are not in direct contact with each other due to the spacer 8, the squeak noise and the like can be reduced.

  Further, the other side 8c of the spacer 8 is a through hole into which an attaching means 4b such as a countersunk screw for attaching to the handrail support member 2 is inserted into an area overlapping the panel attachment hole 4a (see FIG. 3) in the panel 4. 8d is formed. For this reason, when an external force is applied to the handrail and the handrail support member 2 bends, additional stress tends to concentrate on the panel mounting holes 4a of the panel attached to the handrail support member 2 with countersunk screws or the like. Although it becomes easy to enter, since the spacer 8 relieves the applied stress by using the above-described configuration, it is easy to reduce the occurrence of cracks and scratches in the panel mounting holes 4a. In addition, counterbore portions for the attachment means 4b are formed in four portions on the peripheral portion of the through hole 8d.

  In addition, the diameter dimension of the through hole 8d of the spacer 8 is formed smaller than the diameter dimension of the panel mounting hole 4a. The installation state such as the position and inclination of each tread on the staircase is likely to vary, and the installation state of the handrail support member 2 is also likely to vary accordingly. Therefore, the panel 4 is likely to be displaced when attached to the handrail support member 2. However, the diameter dimension of the spacer 8 capable of freely moving the position relative to the panel 4 while absorbing the positional deviation of the handrail support member 2 with respect to the panel 4 by forming the diameter dimension of the panel mounting hole 4a larger. By making it small, it becomes possible to make the attachment state of the attachment means 4b favorable.

  According to the structure for attaching the handrail support member 2 to the tread plate 3 as described above, the handrail support member 2 fixed to the tread plate 3 whose lower end portion is located on the lower stage as a support surface is provided with, for example, a fixing hole. Are attached and fixed directly to the end surface of the tread plate 3 positioned on the upper stage by a fixing tool such as a screw, and the side surface facing one side surface of the handrail column member 2 is positioned on the upper stage by the mounting member 6. Since the handrail support member 2 is attached to the end face of the tread board 3 only by being attached to the end face of the tread board 3 while being pressed to the end face side of the tread board 3, the vertical position relative to the end face of the tread board 3 when the handrail support member 2 is attached. There is no need to perform adjustment and the like, and the mounting operation is very easy, and the handrail column member 2 does not need to be processed to be attached to the end surface of the footboard 3, so the handrail column member accompanying the processing is not necessary. In addition, it may contribute to cost reduction, and depending on the staircase design, the height dimension from the lower stepping plate 3 as the supporting surface to the upper stepping plate 3, that is, the kicking up Although the dimensions are not always the same and are generally different in many cases, according to this mounting structure, the handrail strut member 2 attached to the end surface of the tread plate 3 positioned in the upper stage is used as a common general-purpose member regardless of the kick-up dimensions. It can be used.

  Next, each component used in the above-described structure will be described. FIG. 5 is a schematic perspective view showing the column support 5 used in this embodiment. The column support 5 is made of a substantially L-shaped SPCC (polished steel plate) material having a surface contacting portion with the tread plate 3 as a supporting surface and a portion protruding upward. Two screw holes 5a are provided in the hole 5b and the protruding portion. In addition, the thickness dimension of the support | pillar support body 5 is 3.2 mm.

  FIG. 6 is a schematic perspective view showing the handrail support member 2 used in the present embodiment. The handrail strut member 2 is made of a steel pipe, has a width dimension of 50 mm, a length dimension of 30 mm, and a height dimension of 900 mm, and forms a hollow square pipe with a thickness dimension of 2.3 mm. A screw hole 2a for attaching to the column support 5 is drilled at a position 40 mm in height from the lower edge on both sides, and a position of 245 mm in height and 765 mm from the lower edge is formed on the wide side surface. Two screw holes 2a for attaching the panel 4 to the position are formed at a pitch of 27 mm in the lateral direction. Such a shape can be used as a common member even when the height dimensions of the treads of the staircase, that is, the kick-up dimensions are different, and the manufacturing cost of the handrail strut member 2 can be greatly reduced. .

  FIG. 7 is a schematic perspective view showing the attachment member 6 used in this embodiment. As described above, the attachment member 6 has the attachment body 6a made of SPCC material and the attachment cover body 6b made of PP (polypropylene). FIG. 6 shows the attachment cover body 6b fitted to the attachment body 6a. The flat surface portions at both ends have a vertical width of 20 mm and a horizontal width of 22.4 mm, and the concave portions covering the handrail support member 2 have a width of 30.2 mm and a depth of 49.5 mm. The handrail support member 2 having a vertical width dimension of 30 mm and a horizontal width dimension of 50 mm is attached to the end surface of the tread plate 3 by the recessed portion. Note that attachment holes are formed in both end portions of the attachment body 6a, and the pitch dimension of these attachment holes is 48 mm.

  FIG. 8 is a side view showing the panel 4 used in this embodiment. The panel 4 has a translucent flat plate shape made of PC (polycarbonate) having a thickness of 5 mm, and is formed in an oblique shape with an angle of a width dimension of 670 mm and a height dimension of about 560 mm, and the height width dimension is 520 mm. It is formed in an inclined shape to the extent.

  FIG. 9 is a schematic side view showing a support bracket 9 that supports the handrail used in the present embodiment in an oblique direction and is attached to the upper end of the handrail support member 2, and FIG. 10 shows the support bracket 9 of the present embodiment. It is a schematic end view. The column bracket 9 has two fitting insertion portions 10 that are fitted into the hollow portion of the handrail column member 2 from the upper end, and projecting portions 11 that project upward to a height of 30 mm at both ends of a distance dimension of 6.3 mm. The column bracket 9 </ b> A includes a column bracket 9 </ b> B that includes the insertion portion 12 having a width of 6 mm and is inserted between the protruding portions 11 and includes the curved surface portion 13 that supports the handrail member 1. The support bracket 9B can be freely attached to the support bracket 9A at a support angle. A through hole 15 into which a screw 14 is inserted is formed at the upper end portion of the handrail support member 2, and the screw 14 is screwed into a screw hole 16 formed in the fitting insertion portion 10 of the support bracket 9A. Thus, the support bracket 9A is attached to the handrail support member 2. Further, a screw 18 is inserted into a through hole 17 provided in one of the protrusions 11 of the support bracket A and screwed into a screw hole 19 formed in the insertion part 12 of the support bracket B. The support bracket B with respect to the support bracket A is supported and fixed by being screwed into a screw hole 20 provided on the other side of the portion 11.

  The mounting structure of the handrail strut member shown in this embodiment can be used for stairs with any inclination angle, and is specified in the Building Standards Act as a safety standard in order to prevent as much as possible the possibility of accidents such as falling. The relationship between the lifting dimension X from the supporting surface to the tread plate 3 positioned on the upper stage and the treading dimension Y on the supporting surface can be used for the staircase represented by X / Y ≦ 23/15. As defined in BL (Better Living), the relationship between the kicking dimension X from the support surface to the tread plate located on the upper stage and the tread surface dimension Y on the support surface as a reference that the staircase is too low to be difficult to climb, It is also possible to use it for the staircase shown by X / Y ≧ 150/195.

  Moreover, the attachment structure of the handrail support | pillar member shown to this embodiment is applicable also to a spiral staircase etc. besides a linear staircase.

  Furthermore, the structure which attaches a panel to the handrail support | pillar member as mentioned above is applicable also when attaching a handrail to a flat part other than the staircase shown in the said embodiment.

Next, the case where the handrail support | pillar member used in this invention is used for the flat support surface different from stairs, such as a corridor, is demonstrated, for example.
FIG. 11 is a schematic front view for explaining the mounting structure when the handrail support member used in the present invention is used on a flat support surface. The mounting structure of the handrail support member 30 uses a support base 31 that is provided on a flat support surface such as a corridor and supports the handrail support member 30 in a standing state. As shown in FIG. 12, the column base 31 includes a plate-like base portion 32 having a rectangular shape in plan view that is in contact with the support surface, and a tubular portion 33 having a rectangular shape in a horizontal sectional view extending upward from the plate-like base portion 32. Prepare. The plate-like base portion 32 is provided with fixing holes 32a for fixing to the support surface by fixing means such as screws. The fixing holes 32 a are provided at six locations on the edge of the plate-like base portion 32 and at one location in the approximate center. Note that, at each end edge of the plate-like base portion 32, a substantially V-shaped cutout portion 35 is formed for positioning when attached to the support surface. The handrail support member 30 is attached to the support base 31 having such a configuration via the base cover 36. The base cover 36 has a lid-like form with an open lower end attached to cover the tubular portion 33 in the support base 31 from above, and reduces the gap between the tubular portion 33 and the handrail support member 30.
