BACKGROUND OF THE INVENTION
The present invention relates to an intermediate stage structure that is arranged in a hollow portion from the first floor to the upper floor of a building.
[0002]
[Prior art]
A conventional intermediate stage (hereinafter referred to as “skip floor”) structure in a middle- and low-rise house is generally designed as a part of a structural frame of a building, and an example of the structure will be described with reference to FIG. FIG. 3 is a schematic diagram showing an example of the structure of the skip floor.
[0003]
In FIG. 3, the skip floor S includes a column 52 shorter than the normal first and second floor columns 51 of the building, and supports the beam 53 of the skip floor S in the middle and the normal first and second floor columns 51. The column 55 is supported by a column 54 having the same length, and a column 55 longer than the ordinary first- and second-floor columns 51 is arranged above the beam 53 of the skip floor S. An ordinary second-floor beam 56 is supported by 51 and constitutes a part of the structural frame of the building.
[0004]
In addition, braces 57 and 58 for securing the seismic performance of the structural frame of the building are attached between the pillars 52 and 55, respectively, between the skip floor S and the normal 1st and 2nd floor floors of the building. Stairs (not shown) are attached respectively.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional example, the beam 53 of the skip floor S and the columns 52 and 54 that support the beam 53, the column 55 that supports the ordinary beam 56 of the second floor, and the skip floor S and the ordinary first and second floors. The structural calculation is complicated because the staircase provided between the floor and the floor is designed as a part of the structural frame of the building. The shape of the structural members used is limited and the number of parts increases to ensure strength. There is a problem that construction takes time and the construction period becomes long.
[0006]
In addition, since columns 51, 52, and 55 having different lengths and columns 54 that support beams 53 in the middle are required, the types of columns to be used are increased, and accordingly, braces 57 and 58 having different lengths are required. Therefore, the types of braces used are also increased. Moreover, since the outer wall material according to the length of the pillars 52 and 55, the interior base material, or the window frame is required, these types are also increased. Further, if several kinds of floor raising levels of the skip floor S are set, there is a problem that the types of the above-described members are further increased and manufacturing and management costs are increased.
[0007]
Recently, in order to enrich the living environment, there is a growing need for a well-lit and well-ventilated living space, and it is desired to secure a large living space with a high ceiling and large windows.
[0008]
The present invention solves the above-mentioned problems, and its object is to provide an intermediate space arranged in the atrium from the first floor to the upper floor of the building in order to secure a large living space with a high ceiling and large windows. Focusing on the stage structure, providing the stage part independently from the building structural frame increases the degree of freedom in the shape of the structural members that are easy to use, and reduces the number of parts and types of parts. It is intended to provide an intermediate stage structure that is easy to construct.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, an intermediate stage structure according to the present invention is an intermediate stage structure that is arranged in an atrium from the first floor to the upper floor of a building, and is provided on the floor of the first floor independently of the structural frame of the building.
