Abstract

PURPOSE:To effectively utilize spaces by a method in which the first step and the second step are set from the floor of n-staircase to the floors of n-one(1) staircases in such a way as to mutually cross them from sides. CONSTITUTION:Two landings 2 are provided on both ends of a stair room 1, stairs 7 and 9 are provided between the standings 2 and the subordinate intermediate landing 8 in such a way as to mutually cross them from sides. Two steps 11 and 13 are provided between the landing 8 and the first floor in such a way as to mutually cross them from side view. Given steps can be set in small areas.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a staircase structure for a concrete structure such as a shopping center, and in particular, the present invention relates to a staircase structure for a concrete structure such as a shopping center. Regarding things that can be used.

[Prior Art] In the case of large concrete structures such as shopping centers, two or more stairs may be required to be installed on one floor. In that case, for example, the fourth
Staircase structures as shown in the figure will be installed at two locations.

First, there is an entrance/exit 103 for entering/exiting the stairway 101 . A staircase 105 is installed in the staircase room 101, and the staircase 105 communicates with an intermediate landing 107. A staircase 109 is installed from the intermediate landing 107 to further connect to the lower floor.

In order to install this kind of stairs, for example, a=3.0
m, b = 5.0 m, and requires an installation area of about 15 resistance.

Staircase structures with such a configuration are installed at three or more locations.

[Problem to be solved by the invention]

According to the above-mentioned conventional configuration, in order to install a predetermined staircase structure, a large area is required (less than 15
rrrx2) If the original purpose was, for example, a shopping center, there was a problem in that the sales floor area would be narrowed.

The present invention has been made based on the above points, and its purpose is to provide a stair structure that allows for the installation of predetermined stairs in a small area, thereby making it possible to utilize space effectively. It is about providing.

[Means to solve the problem]

In order to achieve the above object, the staircase structure according to the present invention has n
In a staircase structure that connects a staircase on the (n-1) floor to a staircase on the (n-1) floor, the first staircase and the This is characterized by the fact that the two staircases are installed so that they intersect with each other when viewed from the side.

[Function] The first staircase and the second staircase are installed so as to intersect with each other when viewed from the side, from the floor of the staircase on the nth floor to the floor of the staircase on the (n-1) floor.

Therefore, the two staircase structure can be realized with a small installation area, and the space can be used effectively.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Figure 1 is a cross-sectional view of a concrete structure to which the staircase structure according to the present embodiment is applied, and Figure 2 is a cross-sectional view of the concrete structure to which the staircase structure according to the present embodiment is applied.
The sectional view taken along the line ■-■ in the figure, and FIG. 3 is a perspective view.

The concrete structure shown in the figure is a four-story building, and we will focus on the staircase structure that connects the second floor to the first floor. As shown in Figure 2, two landings 2.2 are installed at both left and right ends of the staircase l on the second floor.
Each of these two landings 2.2 is provided with an entrance/exit 3.5.

Further, between each of the landings 2.2 and the intermediate landing 8 below, a staircase 7 and a staircase 9 are installed so as to intersect with each other when viewed from the side. Furthermore, two staircases 11 and 13 are installed between the intermediate landing 8 and the first floor so as to intersect with each other when viewed from the side. The situation is shown in Figure 3. Reference numeral 15 in FIG. 3 is a hallway.

Also, the distance (h) between the bottom surface of the second floor and the floor surface of intermediate landing 8 and the distance (h) between the bottom surface of intermediate landing 8 and the first floor floor (
h) is, for example, 2.1 m, so the distance between the bottom of the second floor and the first floor is (ho) (2,
IX2) m plus the thickness (a) of the intermediate landing 8.

In this way, there are two doorways 3.5 in one staircase room 1.
By installing two sets of stairs 7.9.11.13 each, two sets of stairs can be installed in a small area.

This also applies between the third and second floors and between the fourth and third floors, and the same parts in FIG. 1 are denoted by the same reference numerals and their explanation will be omitted.

As described above, according to this embodiment, two sets of stair structures can be installed in a small area (for example, the area of one conventional staircase), so that the space can be used effectively. Therefore, in the case of the original purpose of the structure, for example, a shopping center, the sales area can be expanded.

Note that the present invention is not limited to the above embodiment.

First, the position of the entrance/exit 3.5 is not limited to the location shown in the figure, and two or more entrances/exits may be installed.

Further, in the above embodiment, the intermediate landing 7 is provided, but this may not be provided and a staircase may be provided directly up to the first floor.

Furthermore, it is also conceivable to install a landing in the center of the stairwell 1 and install stairs from this landing toward both sides.

[Effects of the Invention] As detailed above, according to the staircase structure according to the present invention, n
The first and second stairs are installed so that they intersect with each other when viewed from the side, from the floor of the stairway on the (n-1)th floor to the floor of the stairway on the (n-1)th floor. structure can be realized, and space can be used effectively.
