Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stair structure in a unit building,
In detail, the main frame is formed by spanning the upper and lower ends of the pillars installed at the four corners, respectively, between adjacent pillars, or at least basic structures such as walls and floors are attached to this main frame. The present invention relates to a stair structure in a unit building that is equipped with a structure sufficient to form a living space.

For this reason, modular buildings require mass-produced units of the same type to be manufactured in a form that allows for many variations in combinations, so that the various types of floor plans desired by the owner can be accommodated. In order to meet these demands, a multi-story structure is inevitably required, and it becomes necessary to construct stairs that span both upper and lower story units.

Therefore, it has become common knowledge that stairs in conventional buildings are installed from the floor of the lower floor to the floor of the upper floor. They also set the riser dimensions.

However, since the above-mentioned unit building is constructed in such a way that the lower and upper floors are manufactured separately and then assembled, if the above-mentioned conventional approach is followed as is, the assembly structure of the stairs will be difficult. It had the disadvantage of complicating things.

In other words, as mentioned above, there is a lower beam member on the upper floor, and the floor surface of the upper floor is set on the top surface of this lower beam member, so when the upper floor is assembled on the lower floor, A dead space equal to the total dimension of the beam member and the upper beam member on the lower floor is created, and therefore a staircase section must be provided on the upper floor to absorb this dead space, making the structure unavoidably complicated. Also, the manufacturing process becomes complicated.

Therefore, the present invention was devised to solve these drawbacks, and specifically, the present invention has been devised to solve these drawbacks. A unit type building in which a unit frame is formed by installing materials, and these unit frames are stacked up and down, and a staircase is provided between an upper floor unit frame and a lower floor unit frame, the landing part at the top of the staircase. is provided in the same plane as the upper surface of the upper beam of the lower floor unit frame, and approximately the distance from the mating surface of the upper beam of the lower floor unit frame and the lower beam of the upper floor unit frame to the upper surface of the lower beam of the upper floor unit frame. The unit riser dimension of the stairs is set to have a length equal to y.

Therefore, since the stairs can be attached to the lower floor all at once when the lower floor is manufactured, in other words, because the stairs can be constructed independently of the upper floor unit frame, the stairs can also be installed on the upper floor, as in the conventional structure mentioned at the beginning. There is no need to provide a separate unit, which simplifies the overall structure, especially the structure of the upper floor unit frame, and also facilitates manufacturing and processing, which has the advantage of being rational in terms of manufacturing cost and construction period.

Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, 1 is a lower floor unit frame, 2 is an upper floor unit frame stacked above it, and a circular staircase 3 is provided between both unit frames.

Each of the unit bodies 1 and 2 has pillar materials 1A at the four corners, respectively.
2A..., and at the upper and lower ends of each of these pillar members..., 2A..., each beam member 1a extends between the adjacent ones.
..., 2a... are provided.

An upper end landing portion 4a is formed at the top of the stairs 3, and this landing portion 4a is formed on approximately the same plane as the upper surface of the upper beam 1a of the lower floor unit frame 1, and is The unit of the staircase 3 has a length h' that is approximately equal to the distance from the mating surface A of the upper beam 1a of the unit frame 1 and the lower beam 2a of the upper floor unit frame 2 to the upper surface of the lower beam 2a of the upper floor unit frame 2. The riser dimension h is set.

In addition, 2R in the figure indicates the room of the upper floor unit frame 2, and 4b is the floor surface of the upper floor unit frame 2 that continues from the upper landing portion 4a, which is the floor slab S2 of the room 2R.
It is the same surface as the top surface.

4 is a landing that collectively refers to this upper end landing portion 4a and this floor surface 4b.

Further, S1 is the floor slab of the lower floor unit frame 1, and 5
is the landing in the lower floor unit frame 1 of the stairs 3, and 6 is the atrium.

G is used for installing various piping and wiring for each frame after each frame is assembled in a space called a grid.

In some cases, it may also be used as a storage room or an alcove that communicates with the internal space of each unit frame.

In addition, the planar shape of the upper landing portion 4a and the floor surface 4b of the upper floor unit frame 2 is a matter to be set appropriately, as shown in FIG. It's not something you can do.

When assembling the rotating staircase 3, the upper end of the rotating staircase 3, as shown by the upward arrow in FIG.
In addition, the upper end landing portion 4a is raised to a position where the upper surface of the upper end landing portion 4a is approximately at the same level as the upper surface of the upper beam 1a of the lower floor unit frame 1, and fixed at that position, and furthermore, as shown by the downward arrow in the figure. The upper floor unit frame 2 is lowered to a position where it can be stacked on top of the lower floor unit frame 1, and assembled as shown in FIG.
