Abstract

(57) [Summary] [Purpose] To increase the effective width of stairs by mounting them so that adjacent handrails are as close as possible. The ends of the handrails are closed by supporting columns so that adjacent handrails do not have to be continuous at the corners. [Structure] Lower stairs 2a provided from the floor on the lower floor to the landing 3 and upper stairs 2b provided from the landing 3 to the floor on the upper floor
Is arranged so as to be folded back in a U shape when seen from a plane. The handrail 4 is arranged along the edge on the side where the lower staircase 2a and the upper staircase 2b are adjacent to each other. Support pillars 9 are erected on the floor of the upper floor, the landing 3, and the beams at the end of the floor of the lower floor. The ends of the handrails 4 are connected to and supported by the support columns 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure used to support a handrail attached along a stair by a support column.

[0002]

[Prior art]

 Conventionally, when a staircase 2 is provided in a staircase 1 of a building, as shown in FIGS. 5 and 6, a lower staircase 2a provided from a floor on a lower floor to a landing 3 and a floor 3 from a landing 3 to an upper floor are provided. The staircase 2b and the staircase 2b are formed so as to be folded back in a U shape when seen from a plane. Then, the handrail 4 is arranged along the edges of the lower staircase 2a and the upper staircase 2b adjacent to each other. The handrail 4 is formed by mounting a large number of vertical grids 7 between the upper rail 5 and the lower rail 6, and mounting a handrail bar 8 along the upper rail 5 above the upper rail 5. The support pillar 9 for supporting the handrail 4 is erected by attaching the lower end to the sasara girder 10 as shown in FIG. 7, and the handrail 4 standing along the sasara girder 10 is erected on the sasara girder 10. It is attached to the supporting column 9.

[0003]

[Problems to be solved by the device]

 In such a conventional example, since the supporting pillar 9 is erected on the sasara girder 10 and the middle of the handrail 4 is attached to the supporting pillar 9, a certain gap S or more is provided between the adjacent handrails 4. Without it, the handrails 4 cannot be attached, and the gap S 1 must be provided between the adjacent handrails 4, so that there is a problem that the effective width of the stairs 2 becomes narrow. In addition, at the landing 3 and the corner of the middle floor, there is a problem that the ends of the adjacent handrails 4 must be continuous so as to have a U-shape when viewed from above.

The present invention has been made in view of the above problems, and an object of the present invention is to allow adjacent handrails to be attached so as to be as close as possible and to increase the effective width of stairs. Moreover, it is an object of the present invention to provide a support structure for handrails on stairs, which does not require that end portions of the handrails be closed by support pillars so that adjacent handrails need not be continuous at the corners.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the supporting structure of the handrail of the present invention has a lower staircase 2a provided from the floor of the lower floor to the landing 3 and an upper staircase 2b provided from the landing 3 to the floor of the upper floor from a plane. It is arranged so as to be folded back in a U shape when seen, and the handrail 4 is arranged along the edge on the side where the lower staircase 2a and the upper staircase 2b are adjacent to each other, and the handrail 4 is arranged on the upper floor, the landing 3 and the lower floor. A support pillar 9 was erected on the beam 11 at the end of the floor, and the end of each handrail 4 was connected to and supported by the support pillar 9.

[0006]

[Action]

 According to the above configuration, the support pillar 9 is erected on the beam 11 at the end of the floor of the upper floor, the landing 3 and the floor of the lower floor, and the end of the handrail 4 is connected to the support pillar 9, The handrail 4 can be supported even when a pair of supporting columns 9 are erected in close proximity to the support column 11, and the adjacent handrails 4 can be brought close together without a gap to widen the effective width of the stairs 2. Further, since the adjacent handrails 4 are brought close to each other and the end portions of the handrails 4 are connected to the support pillars 9, the handrails 4 do not have to be continuous at the corners, and the structure can be simplified.

[0007]

【Example】

 In the case of the present embodiment, the building has three floors, and the staircase 1 also has three floors as shown in FIGS. A staircase 2 is provided between the first floor 13 and the second floor 14 and between the second floor 14 and the third floor 15, and a landing 3 is provided in the middle of the staircase 2. In the case of this embodiment, this landing 3 has a balcony shape and is exposed to the outside. The staircase 2 is composed of a lower staircase 2a from the floor on the lower floor to the landing 3 and an upper staircase 2b from the landing 3 to the floor on the upper floor, and the staircase 2a and the staircase 2b are U-shaped when viewed from the plane. It is arranged so that it folds back into a shape. Further, the sasara girders 10 on the edges on the adjacent sides of the stairs 2a and 2b are made close to each other with almost no gap when seen from a plane, and the handrail 4 is arranged on the sasara girder 10.

The handrail 4 is formed by mounting a large number of vertical grids 7 between the upper rail 5 and the lower rail 6, and mounting a handrail bar 8 along the upper rail 5 above the upper rail 5. There is. The support pillars 9 that support the handrails 4 are erected on the floors on the upper floors, the floors on the lower floors, and the beams 11 at the ends of the landing 3. As shown in FIG. 3, a bottom plate 16a of the mounting hardware 16 is placed on the upper surface of the beam 11, and bolts and nuts are fastened to the mounting holes 17 and 18 for mounting. A pair of connecting portions 16b is erected on the mounting hardware 6 so as to project upward, and the lower ends of the hollow pipe-shaped support columns 9 are fitted to the mounting hardware 6, and the mounting holes 19 and 20 are bolted. The lower end of the support pillar 9 is fixed by fastening a nut, and the support pillar 9 is erected. When the support pillar 9 is erected on the beam 11 in this way, the support pillar 9 can be easily made into a bolt / nut without welding, and the bolt / nut can be mounted with good appearance while suppressing the appearance as much as possible. it can. As shown in FIG. 4, the end of the handrail 4 is connected to the support pillar 9 in the state where the support pillar 9 is erected in this way. By this construction, the adjacent handrails 4 can be brought close to each other, and the ends of the handrails 4 can be neatly finished by the support columns 9.

[0009]

[Effect of device]

 In the present invention, as described above, the supporting pillars are erected on the beams at the ends of the upper floor, the landing and the floor of the lower floor, and the ends of the handrails are connected to the supporting pillars. The handrails can be supported even when they are set up close to each other, the adjacent handrails can be placed close to each other without a gap, and the effective width of the stairs can be widened. Since the rails are connected to the support pillars and closed, it is possible to simplify the structure without the need to make adjacent handrails continuous at the corners.
