Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=�8]] By the way, the reinforcing member is directly fixed to the upper surface of the handrail main body, and the handrail main body is directly fixed to the U-shaped metal fittings attached to the wall frame at both longitudinal end faces. That is, since the U-shaped metal fittings and the reinforcing member are fixed to the handrail main body at different positions, the strength of the handrail is not sufficient. Therefore, when attaching a handrail to a columnless structure where there is no column between adjacent handrail panels, since there is no column for fixing the handrail, it is necessary to further improve the strength of the handrail.

[0005] The present invention has been made in view of the above circumstances, and its purpose is to provide a handrail mounting structure that allows for easy and secure fastening of the handrail, and ensures strength, even in a column-less structure where there are no support columns between adjacent handrail panels. [Means for solving the problem]

[0006] The invention described in claim 1 is as shown, for example, in Figures 1, 4 and 6, A mounting structure for a handrail 100, wherein the handrail 100 is attached along the upper end of a surface material (for example, a glass panel 401), The handrail 100 is provided with a base material 5 that is attached to the upper end of the surface material in a state that holds the upper end, A cover material 1 that covers the base material 5, The system comprises a core material 6 housed in a storage space S formed between the base material 5 and the cover material 1, and fixed to the base material 5. A fixing member 300 is provided on a wall surface perpendicular to the aforementioned surface material (for example, the first wall surface W1). The core material 6, the base material 5, and the fixing member 300 are overlapped, and the fastening member B2 penetrates the overlapping position, thereby integrally connecting the core material 6, the base material 5, and the fixing member 300.

[0007] According to the invention described in claim 1, the handrail 100 comprises a base material 5 provided on the upper end of a surface material (e.g., a glass panel 401) while holding the upper end, a cover material 1 covering the base material 5, and a core material 6 housed in a storage space S formed between the base material 5 and the cover material 1 and fixed to the base material 5. A fixing member 300 is provided on a wall surface perpendicular to the surface material (e.g., a first wall surface W1), and the core material 6, base material 5, and fixing member 300 overlap, with a fastening member B2 passing through the overlapping position, thereby integrally connecting the core material 6, base material 5, and fixing member 300. This provides greater strength compared to cases where the fixing member and the base material, and the base material and the core material are fixed individually. Therefore, the handrail 100 can be easily and firmly fixed and supported to the upper end of the surface material and the wall surface. Therefore, even when attaching the handrail 100 to a column-less structure that does not have support columns between the panel materials, sufficient strength can be ensured. Furthermore, by adopting a column-less structure, when viewed from the outside, the absence of columns between the panel materials creates a slim and clean impression, resulting in a high-quality mounting structure for the Handrail 100. Furthermore, by using transparent materials such as glass panels and adopting a column-free structure, it is possible to create a space with a sense of openness, and sunlight can be easily brought in through the materials.

[0008] The invention described in claim 2 is, for example, as shown in Figures 6 and 11, in the mounting structure of the handrail 100 described in claim 1, The lower surface of the core material 6 and the base material 5 overlap, and the fixing member 300 further overlaps below the base material 5, and the fixing member 300, the base material 5 and the core material 6 are connected by the fastening member B2.

[0009] According to the invention described in claim 2, the lower surface of the core material 6 and the base material 5 overlap, and the fixing member 300 further overlaps below the base material 5, so that the fixing member 300, the base material 5 and the core material 6 are connected by the fastening material B2. Therefore, since the fixing member 300 and the fastening material B1 are positioned on the lower surface side of the base material 5, the fixing member 300 and the fastening material B1 are not visible when viewed from the outside, resulting in a good appearance.

[0010] The invention described in claim 3 is, for example, as shown in Figures 6, 8 and 10, in the mounting structure of the handrail 100 described in claim 1, The core material 6 consists of a first member 61 and a second member 62. The first member 61 and the second member 62 are combined to form a cylindrical shape. The first member 61 and the second member 62 are fixed to the base material 5 on one of their overlapping sides.

[0011] According to the invention described in claim 3, the core material 6 consists of a first member 61 and a second member 62, and the first member 61 and the second member 62 are combined to form a cylindrical shape, so the core material 6 has a simple structure and is easy to install. In addition, the overall weight of the handrail 100 can be made lighter. Furthermore, since the first member 61 and the second member 62 are fixed to the base material 5 on one of their overlapping sides, sufficient strength can be ensured.

[0012] The invention described in claim 4 is, for example, as shown in Figures 6, 8 and 10, in the mounting structure of the handrail 100 described in claim 1, The base material 5 includes a holding portion 7 that holds the upper end of the surface material, The holding portion 7 is characterized by being arranged adjacent to the storage space S.

[0013] According to the invention described in claim 4, the base material 5 is equipped with a holding portion 7 that holds the upper end of the surface material, so the surface material can be securely held by the holding portion 7. Furthermore, since the holding portion 7 is positioned adjacent to the storage space S, the strength of the holding portion 7 is also ensured by the core material 6 stored in the storage space S.

[0014] The invention described in claim 5 is, for example, as shown in Figures 1, 2, and 4, in the mounting structure of the handrail 100 described in claim 1, The aforementioned wall surface W comprises a first wall surface W1 and a second wall surface W2. The handrail 100 is positioned between the first wall surface W1 and the second wall surface W2. The ends of the handrail 100 in the longitudinal direction that are on the side of the first wall surface W1 are fixed to the first wall surface W1 via the fixing member 300. The fixing member 300 comprises a first fixing piece 301 fixed to the first wall surface W1 and a second fixing piece 302 fixed to the core material 6. The core material 6 and the base material 5 overlap, and the second fixing piece 302 further overlaps the base material 5, with the fastening material B2 penetrating and fixing the second fixing piece 302, the base material 5, and the core material 6.

[0015] According to the invention of claim 5, the wall surface W includes a first wall surface W1 and a second wall surface W2, a handrail 100 is disposed across between the first wall surface W1 and the second wall surface W2, and an end portion on the first wall surface W1 side among both end portions in the longitudinal direction of the handrail 100 is fixed to the first wall surface W1 via a fixing member 300. Further, the fixing member 300 includes a first fixing piece 301 fixed to the first wall surface W1 and a second fixing piece 302 fixed to the core material 6. The core material 6 and the base material 5 overlap each other, and the second fixing piece 302 further overlaps the base material 5, and an adhesive material B2 penetrates and fixes the second fixing piece 302, the base material 5, and the core material 6. Therefore, by attaching the fixing members 300 to the first wall surface W1 and the second wall surface W2 respectively and fixing them via the respective fixing members 300 at both end portions in the longitudinal direction of the handrail 100, the handrail 100 can be installed easily and firmly. Further, since the handrail 100 is disposed between the first wall surface W1 and the second wall surface W2 and the handrail 100 is fixed at both end portions in the longitudinal direction thereof, sufficient strength can be ensured even when the handrail 100 is attached to a structure without a column.

Effect of the Invention

[0016] According to the present invention, it is possible to provide a mounting structure for a handrail that can easily and firmly fix the handrail and ensure strength even in a columnless structure where there is no column between adjacent handrail panels.

[0018] Embodiments will be described below with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The scope of the present invention is not limited to the examples shown in the drawings, as the drawings are provided for illustrative purposes only.

[0019] [Handrail mounting structure] Figure 1 is a front view showing the handrail attached to the upper end of the handrail panel. Figure 2 is a cross-sectional view taken along the line ii-ii in Figure 1, and Figure 3 is a cross-sectional view taken along the line iii-iii in Figure 1. The handrail 100 is provided at the upper end of the handrail panel 400. The handrail panel 400 is preferably, for example, a balcony handrail panel, a handrail panel for an exterior corridor of a detached house or apartment building, a handrail panel facing an indoor atrium, or a handrail panel for a staircase. The following description will use the case of application to a balcony handrail panel as an example. In particular, the case of application to a column-less structure in which no support columns are placed between adjacent handrail panels will be described, but the present invention is not limited to this.

[0020] As shown in Figures 1 to 3, a parapet or similar rising section 200 is erected around the outer perimeter of the building's balcony. A coping 210 is attached to the upper end of the rising section 200. The rising section 200 comprises a wall panel 201 and an exterior cladding 202. The exterior cladding 202 is attached to the front and back surfaces of the wall panel 201 via furring strips (not shown). The wall panel 201 is constructed by assembling frame members into a rectangular shape and attaching facing materials made of plywood or the like to both sides of the frame. Reinforcing frame members are provided vertically and horizontally within the frame.

[0021] The coping 210 is a long, metal piece. The coping 210 is attached to the upper ends of the wall panel 201 and the exterior cladding 202. The coping 210 comprises an upper surface 211, an inner piece 212, and an outer piece 213. The inner piece 212 is suspended downward from the building-side end of the upper surface 211. The outer piece 213 is suspended downward from the outdoor-side end of the upper surface 211. A handrail panel 400 is attached to the upper surface 211 of the coping 210 via a mounting member 230. Multiple handrail panels 400 are attached along the width direction X of the wall panel 201. The width direction X of the wall panel 201 is the direction horizontal to the surface of the wall panel 201 and perpendicular to the vertical direction (up and down direction) Y and the thickness direction (depth direction) Z of the wall panel 201.

[0022] The handrail panel 400 is erected above the upper surface 211 of the coping 210. Examples of handrail panels 400 include glass panels, resin panels, or wooden panels. The following description will use the case where two glass panels 401 are used as an example, but the present invention is not limited thereto. Two glass panels 401 are installed adjacent to each other along the width direction X. When viewed from above, the two glass panels 401 are arranged in approximately a straight line. No support columns are provided between these two glass panels 401. A handrail 100 is continuously attached to the upper ends of the two glass panels 401 along the upper ends.

[0023] The handrail 100 is fixed to a wall surface W that is perpendicular to the glass surface of the glass panel 401. A fixing member 300 is attached to the wall surface W, and the fixing member 300 and the handrail 100 are connected. The wall W comprises a first wall W1 and a second wall W2. A handrail 100 is positioned between the first wall W1 and the second wall W2. Fixing members 300 are attached to the first wall W1 and the second wall W2, respectively. The ends of the handrail 100 that face the first wall W1 are fixed to the first wall W1 via fixing members 300. Similarly, the ends of the handrail 100 that face the second wall W2 are also fixed to the second wall W2 via the same fixing members 300.

[0024] [Fixing components] Figure 4 is an enlarged view of the area P enclosed by the dashed line in Figure 1. Figure 5 is a bottom view of Figure 4. Figure 6 is a cross-sectional view taken along the line vi-vi in ​​Figure 5, and Figure 7 is a cross-sectional view taken along the line vii-vii in Figure 5. As shown in Figure 4, the fixing member 300 is substantially L-shaped in a front view and comprises a first fixing piece 301 and a second fixing piece 302. The fixing member 300 is preferably made of a strong metal such as steel. The first fixing piece 301 is fixed to the first wall surface W1. The second fixing piece 302 is fixed to the core material 6 via the base material 5 of the handrail 100, which will be described later. The first fixing piece 301 and the second fixing piece 302 are in the shape of a substantially rectangular plate. The first fixing piece 301 and the second fixing piece 302 are integrally formed so as to be substantially perpendicular to each other. That is, the first fixing piece 301 is formed at one end in the longitudinal direction of the second fixing piece 302 so as to be substantially perpendicular to the lower surface of the second fixing piece 302. The first fixing piece 301 is fixed to the first wall surface W1 by a fastening material B1. Examples of fastening material B1 include screws and bolts.

[0025] The first wall surface W1 can be, for example, the outer surface of a wall panel 501 that constitutes the building frame. An exterior cladding material 502 is attached to the outer surface of the wall panel 501. A cutout hole 501a is formed in the exterior cladding material 502 at the position where the first fixing piece 301 is attached. The fixing member 300 to which the first fixing piece 301 is attached to the outer surface of the wall panel 501 has a second fixing piece 302 protruding outward from the cutout hole 501a. The cutout hole 501a is filled with caulking material (not shown) so that the first fixing piece 301 is not visible from the outside.

[0026] As shown in Figure 6, the second fixing piece 302 is overlapped below the base material 5 of the handrail 100. The fastening material B2 is driven in from the lower surface of the second fixing piece 302 toward the overlapping base material 5 and core material 6. As a result, the fastening material B2 penetrates the overlapping position of the second fixing piece 302, the base material 5 and the core material 6, and the second fixing piece 302, the base material 5 and the core material 6 are integrally connected. Furthermore, it is preferable that a temporary glass fixing member 8 is provided on the lower surface of the base material 5 of the handrail 100. In this case, it is preferable that a second fixing piece 302 is placed on the lower surface of the temporary glass fixing member 8, and that the fastening material B2 is driven in from the lower surface of the second fixing piece 302 toward the temporary glass fixing member 8, the base material 5, and the core material 6.

[0027] [handrail] Figure 8 is a disassembled side cross-sectional view of the handrail. The handrail 100 comprises a base material 5, a core material 6, and a cover material 1. Preferably, the handrail 100 also comprises a holding part 7, a glass temporary fixing member 8, and a cover fall prevention member 9. The core material 6 is preferably made of a strong metal such as steel or stainless steel. The base material 5 and cover material 1 are preferably made of, for example, aluminum, resin, wood, or stainless steel. The core material 6, base material 5, and cover material 1 are preferably formed by extrusion molding.

[0028] <Base material> The base material 5 is positioned at the upper end of the glass panel 401, which is the handrail panel 400. The base material 5 is elongated along the width direction X of the handrail panel 400. The base material 5 includes a glass panel mounting section 51 and a fixing member mounting section 52. The glass panel mounting section 51 is located on the outdoor side, and the fixing member mounting section 52 is located on the building side. The glass panel mounting section 51 and the fixing member mounting section 52 are integrally formed.

[0029] The glass panel mounting portion 51 has an upward convex shape when viewed in a side cross-section. Inside the glass panel mounting portion 51, the temporary glass fixing member 8 and the retaining portion 7, which are fitted into the upper end of the glass panel 401, are fitted.

[0030] The fixing member mounting portion 52 is approximately L-shaped in a side cross-sectional view. That is, the fixing member mounting portion 52 comprises a horizontal extension piece 521 and an upward extension piece 522. The horizontal extension piece 521 extends horizontally towards the building from the building-side end of the glass panel mounting portion 51. The upward extension piece 522 extends approximately vertically upward from the building-side end of the horizontal extension piece 521. The horizontal extension piece 521 and the upward extension piece 522 are formed integrally. The second member 62 of the core material 6, described later, is positioned on the upper surface of the horizontal extension piece 521, and the second fixing piece 302 of the fixing member 300 is positioned on the lower surface of the horizontal extension piece 521 via the glass temporary fixing member 8, described later. These second fixing piece 302, glass temporary fixing member 8, horizontal extension piece 521, and second member 62 are fastened together with the fastening material B2 (see Figures 6 and 11).

[0031] The upward-extending piece 522 is superimposed on the outside of the first member 61 and the second member 62 of the core material 6, which will be described later, and fixed with the fastening material B3.

[0032] <Temporary glass fastening material> The temporary glass fixing member 8 is fitted onto the upper end of the glass panel 401 before the base material 5, temporarily fixing the glass panel 401 in place. The temporary glass fixing member 8 includes a glass panel mounting portion 81 and a fixing member mounting portion 82. The glass panel mounting portion 81 has an upward convex shape when viewed in a side cross-section. The upper end of the glass panel 401 is directly fitted into the inside of the glass panel mounting portion 81. The fixing member mounting portion 82 is located closer to the building than the glass panel mounting portion 81. The fixing member mounting portion 82 has a roughly L-shape in a side cross-sectional view. The fixing member mounting portion 52 of the base material 5 is positioned on the upper surface of the fixing member mounting portion 82, and the second fixing piece 302 of the fixing member 300 is positioned on the lower surface of the fixing member mounting portion 82 (see Figures 6 and 10). The lower end portion 82a of the fixing member mounting portion 82 is formed in a substantially L-shape when viewed in a side cross-section. The second fixing piece 302, which is positioned on the lower surface of the fixing member mounting portion 82, has its lower surface held by the lower end portion 82a of the fixing member mounting portion 82. Furthermore, the lower end portion 82a covers the building-side side 302a of the second fixing piece 302 (see Figure 10). As a result, when the handrail 100 is viewed from the building side, the second fixing piece 302 is not visible, which is aesthetically pleasing.

[0033] <Holding part> The retaining portion 7 has an upwardly convex shape in a side cross-sectional view. The retaining portion 7 is fitted directly to the upper end of the glass panel 401 at a different position from the glass temporary fixing member 8. Furthermore, the retaining portion 7 is fitted inside the glass panel mounting portion 51 of the base material 5. On the inner surfaces of the holding portion 7, multiple protrusions 71 are formed that project toward the outdoor side and the building side of the upper end of the glass panel 401. These protrusions 71 hold the glass panel 401 by sandwiching its upper end from both sides.

[0034] <Core material> The core material 6 is housed in a storage space S formed between the base material 5 and the cover material 1. The core material 6 is elongated along the width direction X of the handrail panel 400. The core material 6 is fixed to the base material 5. The core material 6 comprises a first member 61 and a second member 62. The first member 61 has a roughly C-shape in a side cross-sectional view. The first member 61 is provided with a covering portion 611 that covers the upper part of the glass panel mounting portion 51 of the base material 5. At the building-side end of the covering portion 611, an L-shaped extension portion 612 is formed in a side cross-sectional view, which extends downward and then horizontally toward the outdoors.

[0035] The second member 62 is provided inside the covering portion 611 of the first member 61 and has a covering portion 621 that covers the upper part of the glass panel mounting portion 51 of the base material 5. A groove-shaped portion 622 is formed at the building-side end of the covering portion 621. The groove-shaped portion 622 extends downward from the building-side end of the covering portion 621, then extends horizontally toward the building, and further covers the extended portion 612 of the first member 61 from the outside.

[0036] The first member 61 and the second member 62 are assembled to form a cylindrical shape. Specifically, the extension 612 of the first member 61 is inserted into the groove-shaped portion 622 of the second member 62, and the wall surface 622a forming the groove-shaped portion 622 and the extension 612 are superimposed. Then, the extended portion 612 of the superimposed first member 61 and the wall surface 622a that forms the groove-shaped portion 622 of the second member 62 are further superimposed on the upward extended piece 522 of the base material 5 and fixed by the fastening material B3 (see Figure 10). Furthermore, the covering portion 611 of the first member 61 covers the covering portion 621 of the second member 62 from above, and the two covering portions 611 and 621 are overlapped and fixed from the upper surface of the covering portion 611 of the first member 61 by fastener B4 (see Figure 10). Examples of fasteners B3 and B4 include screws and bolts.

[0037] <Cover material> The cover material 1 is long along the width direction X of the handrail panel 400. The cover material 1 is installed so as to cover the upper end of the glass panel 401, which is the handrail panel 400.

[0038] <Cover fall prevention material> The cover fall prevention material 9 is attached to the underside of the base material 5 after the cover material 1 has been installed to hold the cover material 1 in place and prevent it from falling off. As shown in Figure 5, the cover fall prevention material 9 is attached to the underside of the base material 5 where the temporary glass fixing member 8 is not provided. The cover fall prevention material 9 is fixed by driving the fastening material B5 towards the underside of the base material 5 (see Figure 13).

[0039] [How to install a handrail] Next, we will explain how to install the handrail 100. Figures 9 to 13 are side cross-sectional views showing the installation method of the handrail.

[0040] (1) As shown in Figures 1 and 4, the first fixing piece 301 of the fixing member 300 is fixed to the wall panel 501, which is the first wall surface W1, with fastener B1. Similarly, the first fixing piece 301 of the fixing member 300 is fixed to the wall panel 501, which is the second wall surface W2, with fastener B1. Furthermore, the exterior material 502 is attached to the wall panel 501 after the first fixing piece 301 of the fixing member 300 is fixed to it. At this time, it is preferable to pre-form a cutout hole 501a in the exterior material 502 corresponding to the position where the first fixing piece 301 is attached, so that the second fixing piece 302 of the fixing member 300 protrudes outward from the cutout hole 501a. For aesthetic reasons, it is preferable to fill the cutout hole 501a with a sealant (not shown) or the like so that it is not visible from the outside.

[0041] The following describes how to install the handrail 100 on the first wall surface W1, but the same procedure can be used to install the handrail 100 on the second wall surface W2.

[0042] (2) As shown in Figure 9, the glass panel mounting portion 81 of the glass temporary fixing member 8 is fitted to the end of the glass panel 401 on the first wall surface W1 side at the upper end. This temporarily fixes the glass panel 401. (3) Insert a post-installation bead (not shown) into the glass panel 401.

[0043] (4) As shown in Figure 10, the retaining part 7 is fitted onto the upper end of the glass panel 401. That is, the retaining part 7 is fitted onto the upper end of the glass panel 401 where the temporary glass fixing member 8 is not attached. As a result, the protrusion 71 of the retaining part 7 clamps the outdoor side surface and the building side surface at the upper end of the glass panel 401. As a result, the glass panel 401 is held in place.

[0044] (5) As shown in Figure 10, a base material with a core material attached is prepared in advance by attaching the core material 6 to the base material 5. Specifically, the first member 61 and the second member 62 are assembled into a cylindrical shape and fixed with fastener B4 to form a core material 6. Then, the core material 6 is placed on the base material 5. The wall surface 622a forming the extended portion 612 of the overlapping first member 61 and the groove-shaped portion 622 of the second member 62, and the upwardly extending piece 522 of the base material 5 are fixed with fastener B3. This creates a base material with a core material. Subsequently, the glass panel mounting portion 51 of the core material-equipped base material is fitted into the holding portion 7. As a result, the upper end of the glass panel 401 is covered and held by the glass temporary fixing member 8, the holding portion 7, the base material 5, the first member 61, and the second member 62.

[0045] (6) As shown in Figure 11, the fastening material B2 is driven in from the lower surface of the second fixing piece 302 of the fixing member 300 toward the second member 62 of the core material 6. As a result, the fastening material B2 penetrates from the lower surface of the second fixing piece 302 through the fixing member mounting portion 82 of the glass temporary fixing member 8, the fixing member mounting portion 52 of the base material 5, and the groove-shaped portion 622 of the second member 62 of the core material 6, thereby fixing the fixing member 300, the glass temporary fixing member 8, the base material 5, and the core material 6.

[0046] (7) As shown in Figure 12, end caps 10 are attached to the longitudinal ends of the cover material 1. It is preferable to form the cover material 1 in advance to a longer length and cut it to the required length on site before use. The cover material 1 with the end caps 10 attached is fitted onto the base material with the core material from above. Note that in Figure 13, the end caps 10 are omitted from the illustration due to drawing limitations.

[0047] (8) As shown in Figure 13, the lower end of the cover material 1 is fitted into the recess 91 of the cover fall prevention material 9 on the lower surface of the base material 5, and the cover fall prevention material 9 is attached with fastening material B5.

[0048] This embodiment provides the following excellent effects. The handrail 100 comprises a base material 5 provided on the upper end of the glass panel 401, holding the upper end; a cover material 1 covering the base material 5; and a core material 6 housed in a storage space S formed between the base material 5 and the cover material 1 and fixed to the base material 5. A fixing member 300 is provided on the first wall surface W1 perpendicular to the glass panel 401, and the core material 6, base material 5, and fixing member 300 overlap. A fastening member B2 penetrates the overlapping position, thereby integrally connecting the core material 6, base material 5, and fixing member 300. This provides greater strength compared to cases where the fixing member and base material, and the base material and core material are fixed individually. Therefore, the handrail 100 can be easily and firmly fixed and supported to the upper end of the panel and the wall surface. Consequently, sufficient strength can be ensured even when the handrail 100 is attached to a column-less structure. Furthermore, by adopting a column-less structure, when viewed from the outside, the absence of columns between the glass panels 401 creates a slim and clean impression, resulting in a high-quality mounting structure for the handrail 100. Furthermore, by using glass panels 401 and a column-free structure, it is possible to create a spacious feel, and sunlight can be easily brought in through the glass panels 401.

[0049] The lower surface of the core material 6 and the base material 5 overlap, and the fixing member 300 further overlaps below the base material 5, so that the fixing member 300, the base material 5 and the core material 6 are integrally connected by the fastening material B2. Therefore, since the fixing member 300 and the fastening material B1 are positioned on the lower side of the base material 5, they are not visible when viewed from the outside, resulting in a good appearance.

[0050] The core material 6 consists of a first member 61 and a second member 62, and the first member 61 and the second member 62 are combined to form a cylindrical shape, resulting in a simple structure for the core material 6, which makes installation easy. In addition, the overall weight of the handrail 100 can be made lighter. Furthermore, since the first member 61 and the second member 62 are fixed to the base material 5 on one of their overlapping sides, sufficient strength can be ensured.

[0051] Since the base material 5 is equipped with a holding portion 7 that holds the upper end of the glass panel 401, the glass panel 401 can be securely held by the holding portion 7. Furthermore, since the holding portion 7 is positioned adjacent to the storage space S, the strength of the holding portion 7 is also ensured by the core material 6 stored in the storage space S.

[0052] The wall W comprises a first wall W1 and a second wall W2, and a handrail 100 is positioned between the first wall W1 and the second wall W2. The ends of the handrail 100 on the side of the first wall W1 are fixed to the first wall W1 via fixing members 300. The fixing member 300 comprises a first fixing piece 301 fixed to the first wall W1 and a second fixing piece 302 fixed to the core material 6. The core material 6 and the base material 5 overlap, and the second fixing piece 302 further overlaps the base material 5, with a fastening material B2 penetrating and fixing the second fixing piece 302, the base material 5, and the core material 6. Therefore, by attaching the fixing members 300 to the first wall W1 and the second wall W2 respectively, and fixing the handrail 100 at both ends in the longitudinal direction via the respective fixing members 300, the handrail 100 can be easily and securely installed. Furthermore, since the handrail 100 is positioned between the first wall surface W1 and the second wall surface W2, and the handrail 100 is fixed at both ends in the longitudinal direction, sufficient strength can be ensured even when the handrail 100 is attached to a column-less structure.

[0053] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the SDGs (Sustainable Development Goals). In the construction industry, efforts are also being made to use wood in buildings to reduce carbon dioxide emissions. Buildings that utilize the above-mentioned handrails can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs by using wood-based materials.

[0054] [Differentiation] The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0055] Figure 14 is a side cross-sectional view showing a modified example of a handrail mounting structure. In this modified example, the first member 61A and the second member 62A of the core material 6A both have a roughly grooved shape when viewed from the side. The first member 61A and the second member 62A are assembled vertically with their grooved bottom surfaces facing each other. The core material 6A assembled in this way has a cylindrical shape. The first member 61A and the second member 62A are fixed together by fasteners B4 on their overlapping outdoor sides. The overlapping building-side sides of the first member 61A and the second member 62A are superimposed on the upward-extending piece 522 of the base material 5 located on the outside of the second member 62A and fixed together by fasteners B3. Except for the core material 6A, the structure is the same as in Figure 6, and the same reference numerals are used for the same components.

[0056] In the embodiment described above, the second member 62 of the core material 6, the fixing member mounting portion 52 of the base material 5, and the second fixing piece 302 of the fixing member 300 were stacked in that order, but the stacking order is not limited to this. For example, the second member 62 of the core material 6, the second fixing piece 302 of the fixing member 300, and the fixing member mounting portion 52 of the base material 5 may be stacked in that order and fixed with the fastening material B2. This allows the second fixing piece 302 to be covered by the base material 5, improving the appearance from the outside.

[0057] In the embodiment described above, there are two glass panels 401, but this is not limited to one. Furthermore, it may be applied to a structure in which supports are provided between adjacent glass panels 401, rather than a support-less structure.

[0058] Furthermore, the shape of the fixing member 300 is not limited to the above embodiment and can be changed as appropriate. Furthermore, instead of directly attaching the first fixing piece 301 of the fixing member 300 to the wall panel 501, a base bracket (not shown) may be attached in advance, and the first fixing piece 301 may be attached to this bracket.
