Abstract

PURPOSE:To make it possible to bear a landing without erecting holders from a floor by constructing H-shaped landing bearing structural materials of studs erected to beams on both sides of a staircase and supporting beams constructed between the studs. CONSTITUTION:Studs 3... are respectively erected to up and down beams 2... located at both sides of a staircase 1, and supporting beams 4 and 4 are constructed between vertical intermediate sections of each of the studs 3... H-shaped landing bearing structural materials 5 and 5 are constituted of the supporting beams 4 and 4 and studs 3... on both sides of them. After that, a plurality of H-shaped landing bearing structural materials 5 and 5 are arranged in parallel, and a staircase landing 6 is formed on the supporting beams 4 and 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a support structure for a stair landing.

[Prior art 1] Conventionally, the landing area 6 of a U-shaped staircase is constructed by assembling a pedestal 12 on a floor 11 as shown in FIG. Ta.

[Problems to be Solved by the Invention] However, in a so-called floor-standing type device in which a pedestal 12 is assembled on a floor 11 as shown in FIG. 4, and a platform 6 is formed on the pedestal 12, It was not possible to create a so-called stacked staircase in which a staircase landing 6 connecting the second and third floors was placed on top of the landing 6 of the stairs connecting the first and second floors. Conventionally, to create this stacked staircase, intermediate beams are placed on both sides of the staircase at a height corresponding to the level of the landing area 6 of the stairs, and a support beam is constructed between the intermediate beams. A platform was formed on top of the support beam, but this required a pillar to support the intermediate beam, which required the following components: the pillar, the intermediate beam, and the support beam.

The present invention was invented in view of the problems of the conventional example described above, and it is possible to easily construct a stacked staircase.Moreover, when constructing a stacked staircase, intermediate beams are provided on both sides of the stairwell. There is no need to provide support structure for stair landings.

[Means for Solving the Problems] The support structure for a staircase platform of the present invention has studs 3 erected on upper and lower beams 2 located on both sides of a staircase chamber 1, and
A support beam 4 is constructed between the vertically intermediate portions of the support beam 4, and the double-opening pillar 3 and the support beam 4 form a platform support structure 5 in the shape of a ``■''.
It is characterized in that a plurality of the above-mentioned H-shaped platform support structures 5 are arranged side by side to form a staircase platform 6 on the support beam 4, and such a structure is By employing this method, the problems of the conventional example described in 1. are solved and the object of the present invention is achieved.

[Function] Therefore, studs 3 are erected on the upper and lower beams 2 located on both sides of the staircase chamber 1, and a support beam 4 is erected between the middle portions of the studs 3 in the vertical direction. An H-shaped platform support structure 5 is formed with the beam 4, and a plurality of the H-shaped platform support structures 5 are arranged side by side to form a staircase platform 6 on top of the support beam 4.
By forming the platform 6, it becomes possible to support the platform 6 without installing a frame from the floor as in the conventional floor-standing type, and moreover, the platform 6 can be supported without installing intermediate beams on both sides of the staircase 1. 3.

[Examples] The present invention will be described in detail below based on examples shown in the accompanying drawings.

Beams 2 are provided at positions corresponding to each floor on both sides of the staircase 1. A stud 3 is erected on each of the upper and lower beams 2 located on both sides of the stairway 1, and a support beam 4 is erected in the middle part of the stud 3 in the vertical direction. 1
A Vt structure 5 for supporting the landing area is formed in the shape of a letter. Then, a plurality of these I-shaped platform support structures 5 (
In the embodiments shown in FIGS. 1, 2, and 3, two of them are arranged in parallel at an arbitrary interval. A joint beam 7 is installed between adjacent support beams 4, and a cantilever beam 8 is installed perpendicularly to the support beam 4 in a portion located on the rear side of the platform 6. It is. Then, a landing area 6 is formed on this using the receiving beam 4, a joint beam 7, and a cantilever beam 8, and the landing area 6 is made of, for example, a panel. Support beam 4 located at the front of the entertainment space
The lower end of the climbing floor #5i9 is attached to one half of the supporting beam 4, and the upper end of the descending staircase 10 is attached and supported to the other half of the support beam 4. The stair landing 6 is supported as described above, but a stair landing 6 connecting the second and third floors is further placed on top of the stair landing 6 connecting the first and second floors. In the case of a so-called stacked staircase, studs 3 are erected on the upper and lower beams 2 located on both sides of the stairwell 1 on the upper floor in the same manner as above, as shown in Fig. A support beam 4 is erected between the intermediate portions of the support beams 4 to form an H-shaped platform support structure 5 with the double-opening columns 3 and the support beams 4, and - the H-shaped platform support structure 5 A staircase platform 6 is formed on the support beam 4 by arranging a plurality of them in parallel.

[Effect of the invention 1 In the present invention, as described above, studs are erected on the upper and lower beams located on both sides of the stairway, and a support beam is erected between the middle portions of the studs in the vertical direction. An H-shaped platform support structure is formed by the open pillars and support beams, and a plurality of the above I-■-shaped platform support structures are installed in parallel to form a staircase platform on top of the support beams. Because of this structure, the landing area can be supported without having to erect a frame from the floor like in the conventional floor-standing type, and the landing area can also be supported without installing intermediate beams on both sides of the staircase. It is.
