Description

The present invention relates to a handrail waist wall.

A handrail waist wall to which a handrail made of a louver or the like is attached may be applied to the waist wall of the balcony. According to the handrail waist wall, it is possible to block the line of sight from the outside to the inside of the balcony while taking light and wind into the inside of the balcony by the handrail made of a louver or the like above it.

Here, there has been proposed a handrail waist wall that makes it possible to view the greened surface from both the inside and outside of the building without pressing the substantial usable area of the balcony. Specifically, a plurality of handrail stanchions are erected along the width direction of the balcony, and the handrail stanchions made of steel are used in balconies in which wall materials are attached to the outdoor side and indoor side of the balconies. The carrying arm is rigidly joined to the structural material of the balcony, and the carry-out arm extends from the handrail strut to the outside of the outdoor wall surface of the handrail wall. Then, a spar is joined to the tip of the carry-out arm, the upper part of the spar is raised up above the handrail wall, the bracket is joined to the upper part, and the planting beam is laid over the bracket. A planting container is placed on the top (for example, refer to Patent Document 1).

JP, 2017-127196, A

The handrail waist wall described in Patent Document 1 has a cantilever structure in which a carry-out arm projects outward from the waist wall, and the louver is supported by the carry-out arm, and thus requires a strong louver support structure.

By the way, it is general that various pattern modules having a predetermined height and width are continuous vertically and horizontally on the waist wall. As for the height of the handrail on the balcony, there are regulations on the height of the handrail on the balcony according to the Building Standards Act and the installation standards for the handrail under the Product Assurance Act (the Act on Promotion of Housing Quality Assurance). Specifically, the Building Standards Act stipulates that the height from the top of the balcony deck be 1100 mm or higher. According to the Product Assurance Act, if the foothold is 650 mm or higher, the handrail height should be higher. If the height of the foothold is less than 650 mm, the height from the waist wall is further increased to 800 mm or more.

Therefore, when the height of the handrail waist wall is set based on such various standards, the above-mentioned handle modules are allocated from the lower end of the waist wall to the top tree of the waist wall (lower end of the louver). In that case, the pattern module cannot be allocated in the vicinity of the topmost tree, and a gap smaller than the height of the pattern module may occur. In this way, the gap formed between the continuous pattern module and the headstock on the waist wall may be a factor that impairs the appearance and design of the balcony and the building.

The present invention has been made in view of the above problems, and does not require a high-strength support structure in a region where a louver is supported on a waist wall, and a handrail waist that can impart excellent appearance design to a balcony and a building. Intended to provide a wall.

In order to achieve the above object, one aspect of the handrail waist wall according to the present invention is:
A louver composed of a plurality of horizontal rails or vertical rails that doubles as handrails is attached directly above the umbrella tree on the waist wall of the balcony.
Kasagi planing material is arranged between the waist wall and the Kasagi,
It is characterized in that the above-mentioned cutout material of the head board has a plurality of fins.

According to this aspect, since the louver is attached to the waist wall of the balcony directly above the umbrella tree, the louver support structure has high strength unlike the cantilever structure in which the louver is carried out from the waist wall to the outdoor side. Is unnecessary. Also, when the handle module cannot be allocated near the head wall of the waist wall and a gap is created between the top handle pattern module and the head tree, the head tree undercutting material is placed in this gap to prevent There is no problem that the exterior design of the balcony and the building is impaired. Further, according to the handrail waist wall of the present aspect, since the headboard undercut has a plurality of fins, it is possible to give a texture to the lower region of the headstock, and enhance the appearance design around the headstock. You can

Furthermore, a continuous handle module on the surface of the waist wall below the Kasaki siding plank, a plurality of horizontal bars or vertical bars of the louver above the Kasagi, and a plurality of fins of the Kasagi siding plan in a row. By being continuous, it is possible to bring out the appearance and design with a change in the pattern, while having the continuous integrity. The waist wall may be a ceramic siding board or a metal siding board, as well as a tile outer wall. In any form, pattern modules having a predetermined height and width are continuous vertically and horizontally.

Another aspect of the handrail waist wall according to the present invention is characterized in that the fins extend along the longitudinal direction of the horizontal rail or the vertical rail of the louver.

According to this aspect, since the longitudinal direction of each of the horizontal rails in the case where the louver is a horizontal lattice or the vertical rails in the case of a vertical lattice and the fins of the Kasaki siding plank are matched, It is possible to create continuous unity over the louver.

In another aspect of the handrail waist wall according to the present invention, the waist wall has a plurality of handle modules of a predetermined height in at least a vertical direction,
The height of the headboard cutout material is less than the predetermined height.

According to this aspect, even when the handle module cannot be allocated in the vicinity of the umbrella tree on the waist wall and a gap is created between the handle module on the uppermost stage and the umbrella tree, the height of the handle module is less than the predetermined height in the gap. By arranging the headboard undercutting material, the gap can be eliminated by the headboard undercutting material, and excellent appearance and design can be imparted to the balcony and the building. Note that "having a plurality of pattern modules in at least the vertical direction" means having a plurality of pattern modules in the vertical direction and having a plurality of pattern modules in the vertical direction and the horizontal direction. Is included.

Another aspect of the handrail waist wall according to the present invention is, in the case where the louver has the cross rail,
The cross rail has a substantially rectangular cross-sectional shape, and both the top end surface and the bottom surface thereof have a downward slope toward the balcony side.

According to this aspect, since the top end surface and the bottom surface of the horizontal rail of the louver both have a downward slope (water gradient) toward the balcony side, rainwater can be guided to the balcony side from the top end surface and the bottom surface of the horizontal rail. Therefore, it is possible to suppress the retention and raindrop of rainwater on the top and bottom surfaces.

In addition, another aspect of the handrail waist wall according to the present invention is characterized in that a drainer having a triangular cross-sectional shape that is depressed upward is formed on the bottom surface.

According to this aspect, since the drainer having a conical shape that is recessed upward on the bottom surface of the cross rail and having a triangular cross-section is formed, it is possible to cut off the rainwater flow at an intermediate position on the bottom surface of the cross rail. it can. Furthermore, when the crossbar of the louver is seen from below, the drainer forms a shadow and contrasts with other parts of the bottom surface, giving the crossbar a three-dimensional effect. It is possible to form balconies and buildings with excellent appearance and design.

As can be understood from the above description, according to the handrail waist wall of the present invention, a high-strength support structure is not required in a region where the louver is supported on the waist wall, and an excellent appearance designability for a balcony and a building is obtained. Can be given.

It is the perspective view which looked at an example of a handrail waist wall concerning an embodiment from the lower part. It is a II-II arrow line view in FIG. 1, Comprising: It is a longitudinal cross-sectional view of an example of a handrail waist wall which concerns on embodiment. It is the longitudinal cross-sectional view which expanded the cross rail of a louver.

Hereinafter, the handrail waist wall according to the embodiment will be described with reference to the accompanying drawings. In the present specification and the drawings, substantially the same components may be denoted by the same reference numerals to omit redundant description.

[Handrail waist wall according to the embodiment]
An example of a handrail waist wall according to the embodiment will be described with reference to FIGS. 1 to 3. Here, FIG. 1 is a perspective view of an example of a handrail waist wall according to the embodiment as viewed from below. Further, FIG. 2 is a view taken along the line II-II in FIG. 1, and is a vertical cross-sectional view of an example of the handrail waist wall according to the embodiment. Further, FIG. 3 is an enlarged vertical cross-sectional view of the cross rail of the louver.

The building having the handrail waist wall 100 shown in FIG. 1 is, for example, a two-story or three-story house such as a steel frame, wooden structure, or reinforced concrete structure, and the handrail waist wall 100 is a balcony provided on the second or third floor. Applied to.

The handrail waist wall 100 has a horizontal lattice louver 50 in which a plurality of horizontal rails 51 also serving as handrails are integrated by a plurality of exterior support columns 52, which is attached directly above the umbrella tree 20 of the waist wall 10 of the balcony. It is formed by arranging a heading material 30 for the heading between the heading and the heading 20.

As shown in FIG. 2, the waist wall 10 includes a waist wall frame 17 formed by assembling a vertical frame member 17a and a horizontal frame member 17b in a frame shape, a side surface of the waist wall frame 17 on the balcony side, and an outdoor side. It is formed by the exterior material 10 ′ attached to the side surface and the headstock 20 attached to the top end of the waist wall frame 17.

In a building, a balcony floor beam (not shown) is made of a shaped steel material such as H-shaped steel, a waist wall frame 17 that constitutes the waist wall 10 is formed of a shaped steel material such as flat steel, and an exterior material 10' is a ceramic material. It is various siding materials such as a system siding material and a metal siding material, and a face material such as a tile outer wall to which a tile is attached. The exterior material of the outer wall of the building to which the waist wall 10 of the balcony is attached is also formed of a siding material or the like made of the same material as the waist wall 10.

As shown in FIG. 1, a plurality of convex portions 11, 12, 13 and concave portions 14, 15 between the convex portions 11, 12, 13 are formed on the surface of the exterior material 10 ′ that constitutes the waist wall 10. The uniform pattern module 16 formed by the above is continuous vertically and horizontally. In the handle module 16 of the illustrated example, the relatively low (width narrow in the height direction) convex portions 11 and 12 and the relatively high (width wide in the height direction) convex portion 13 are relatively high ( It is formed by interposing a recess 14 having a wide width and a recess 15 having a relatively low width (narrow width). There are various pattern modules to be applied other than the illustrated example.

As shown in FIG. 2, the height of the handle module 16 is t1, and in FIGS. 1 and 2, the handle module 16 of a predetermined integral multiple is allocated from a position below the balcony floor beam (not shown) to the vicinity of the headstock 20. Has been done.

A head joint 18 made of a shaped steel material such as flat steel is arranged at the top end of the waist wall frame 17, and a head tree receiver 21 is arranged on the head joint 18. The head joint 18 and the headrest 21 are fixed to the top end of the waist wall frame 17 with a common screw or the like.

Further, the leg surface of the steel handrail support 23 is fixed to the head joint 18 with a tightening bolt 22 such as a hexagon bolt through a water blocking packing 22a. The steel headboard 20 has a through hole (not shown) at a position corresponding to the handrail support pillar 23, and is attached to the headstock receiver 21 in a posture in which the handrail support pillar 23 penetrates the through hole. A water stop material made of EPDM rubber (ethylene propylene rubber), polyethylene rubber, or the like is attached to the leg surface of the handrail support column 23 so that rainwater does not enter the waist wall frame 17 through the gap between the head joint 18 and the handstop 18. Preferably.

The horizontal lattice louver 50 is provided with a plurality of horizontal bars 51 made of aluminum and having a substantially rectangular cross section (seven in the illustrated example), and each horizontal bar 51 is similarly attached to a plurality of aluminum exterior support columns 52 to be integrated. It is said that. A handrail furring strip 56 is horizontally installed on the upper ends of the plurality of exterior support columns 52, and a handrail 57 is fitted into the handrail furring strip 56 from above to form the louver 50 also serving as the handrail. As shown in FIG. 2, by fixing the exterior support column 52 to the handrail support column 23 with the tightening bolts 53, the louver 50 is attached to the waist wall 10 of the balcony immediately above the headstock 20. The louver may be in the form of a vertical grid having a plurality of vertical bars.

In this way, since the louver 50 is attached directly above the headstock 20 of the waist wall 10 of the balcony, for example, as in the case of a cantilever structure in which the louver is attached to a position protruding from the waist wall to the outdoor side, A high-strength support structure is not required at the site where the louver is supported on the wall. As described above, in the handrail waist wall 100, the exterior support column 52 of the louver 50 mounted on the top end of the waist wall 10 is bolted to the handrail support column 23 that stands upright at the top end of the waist wall 10. A simple joint structure is applied.

As shown in FIG. 2, on the bottom surface of the waist wall 10 on the balcony side, a base plate 41 is placed on a floor panel (not shown), and a waterproof sheet (not shown) is placed on the base plate 41. The balcony deck 40 is formed by arranging the floor finishing material 42 on the waterproof sheet.

The waist wall 10 is vertically arranged on both sides of the waist wall frame 17 on the outdoor side and the balcony side so that the corresponding handle modules 16 are at the same height level. In FIG. 2, although three handle modules 16 are shown in the height direction on the outdoor side of the waist wall frame 17, for example, from a face material having about five to eight handle modules 16 in the height direction. The outer packaging material 10 ′ is applied. Further, the height t1 of one handle module 16 can be set to, for example, about 200 mm to 400 mm.

On the other hand, in the handrail waist wall 100, the height t5 from the balcony deck 40 to the handrail 57 at the top of the handrail waist wall 100 is set by various standards. According to the height regulation of the handrail on the balcony according to the Building Standard Act, the height t5 is regulated to 1100 mm or more. According to the product accuracy method, when the height t3 to the top of the headstock 20 which is a foothold is 650 mm or more, the height t5 is defined as 1100 mm or more, and when the height t3 is 300 mm or more and less than 650 mm, the louver 50 is used. Height t4 (height from the heading 20 serving as a foothold to the handrail 57) is specified to be 800 mm or more. Furthermore, when the height t3 is less than 300 mm, the height t5 is defined to be 1100 mm or more as in the Building Standards Act.

In the handrail waist wall 100, if the height t3 is set to 650 mm and the height t5 is set to 1100 mm, the height level of the headstock 20 is automatically determined (in this example, the height of the balcony deck 40 is 650 mm). That). On the other hand, in the exterior material 10′ that constitutes the waist wall 10, the handle modules 16 having a plurality of heights t1 are vertically arranged from the lower end thereof. Therefore, a height t2 (t2<t1) at which the height t1 required for allocating the last handle module 16 cannot be secured is often left below the headstock 20, and in such a case, the remaining height is left. The range of the height t2 is a gap where the handle module 16 does not exist.

The handrail waist wall 100 eliminates the generation of a gap by disposing the headboard undercutting material 30 in the range of the height t2. The headboard undercutting material 30 has a plurality of (five in the illustrated example) fins 31 along the longitudinal direction of the horizontal rails 51 of the louver 50, and has a separate water return fin 32 at the uppermost stage. Like the louver 50, the Kasaki underlaying material 30 is made of aluminum and may have the same color as the louver 50, or may have an intermediate color between the louver 50 and the exterior material 10′.

In the handrail waist wall 100, even when the handle module 16 cannot be allocated in the vicinity of the shed 20 of the waist wall 10 and a gap is created between the uppermost handle module 16 and the shed 20, the shed bottom cutout material in this gap. By disposing 30, the appearance design of the balcony and the building is not impaired by the gap. Further, since the headboard undercutting material 30 has the plurality of fins 31, it is possible to give a texture to the lower region of the headboard 20 and enhance the appearance design around the headboard 20.

Furthermore, the continuous handle module 16 on the surface of the waist wall 10 below the headboard cutout member 30, the plurality of horizontal rails 51 of the louver 50 above the headstock 20 and the plurality of headboard bottom cutout members 30 have. Since the fins 31 are continuously connected, it is possible to provide the appearance and design with a change in the pattern while having the continuous integration. In particular, in the handrail waist wall 100, the longitudinal direction of each of the horizontal rails 51 of the louver 50 and the fins 31 of the headboard undercut 30 is the same, and the projections 11 and 12 of the handle module 16 are the same. The continuous direction becomes even more conspicuous by matching the longitudinal directions of the two with these.

As shown in FIGS. 2 and 3, the cross rail 51 of the louver 50 has a substantially rectangular cross section, and both the top end surface 51a and the bottom surface 51b thereof have a downward slope toward the balcony. The vertical side surfaces 51c and 51d on the outdoor side and the balcony side are connected to the top surface 51a and the bottom surface 51b.

Since both the top surface 51a and the bottom surface 51b of the horizontal rail 51 have a downward slope (water gradient) toward the balcony, rainwater can be guided from the top surface 51a and the bottom surface 51b of the horizontal rail 51 to the balcony side. The retention of rainwater on the top surface 51a and the bottom surface 51b and raindrops in the Y1 direction and the Y3 direction can be suppressed.

Further, as shown in FIG. 3, on the bottom surface 51b of the horizontal crosspiece 51, there is formed a drainer 51e having a bottom-like recessed shape and a triangular cross-sectional shape.

Since the drain 51e that is depressed upward is formed on the bottom surface 51b of the horizontal rail 51, the rainwater flowing from the vertical side surface 51c at the midpoint of the bottom surface 51b of the horizontal rail 51 can be cut in the Y2 direction. Further, when the louver 50 is viewed from the diagonally lower X direction shown in FIGS. 1 and 3, the drainer 51e having a triangular cross-section on the bottom surface 51b of the horizontal rail 51 forms a shadow and forms another shadow on the bottom surface 51b. A contrast can be added between the parts. By this action, the horizontal crosspiece 51 can be given a three-dimensional effect, and a balcony and a building having a more excellent appearance and design can be formed.

In addition, it is possible to quickly cut off the flow of rainwater that has flowed from the outer end surface of the horizontal rail 51 to the bottom surface 51b, and a drainer 51e formed on the bottom surface 51b of the horizontal rail 51 from below can be installed from below or diagonally below the building. In order to make it visible, it is preferable that a drainer 51e is formed on the bottom surface 51b of the horizontal rail 51 as close to the outdoor side as possible.

It should be noted that other embodiments in which other constituent elements are combined with the above-described configurations and the like may be combined, and the present invention is not limited to the configurations shown here. This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
