[Background technology]
2. Description of the Related Art In recent years, unit buildings constructed by combining a plurality of building units manufactured in advance at a factory at a construction site are frequently used as buildings for use in houses and the like. In general, a building unit is transported to a construction site and then combined with other building units adjacent to each other in the front-rear, left-right, and up-down directions to form a unit building.
[0003]
However, there may be employed a structure in which building units that are adjacent to each other in a plan view are installed at intervals, and the building units are connected by a joint beam (conventional example: JP-A-8-21024).

[Problems to be solved by the invention]
In the above-described conventional example, since the floor panel is mounted on the joint beam, it is necessary to manufacture the beam and the floor structure separately and attach them on the site, which requires cost and labor. In addition, in the conventional example, if the beam back of the joint beam is not kept below the beam back of the ceiling beam of the building unit, the ceiling height will be lowered, so the beam back of the joint beam cannot be increased. there were.
[0005]
Furthermore, since the upper end of the joint beam and the upper end of the lower floor unit are almost at the same height and the position of the joint beam cannot be raised, there is a problem that the ceiling height of the first floor cannot be increased. In order to use the living room comfortably, it is desirable to have a more effective function in consideration of the ceiling design in addition to increasing the ceiling height. For example, in the case of a raised ceiling that is considered to be aesthetically pleasing, the length of the folded part is taken into account, and a new function that can make the room space comfortable in the folded part is improved. Leads to. In addition, it is desirable to provide a housing structure that can smoothly cope with the barrier-free problem of houses that have been urgently responding in recent years and the problem of elderly care at home. For example, by taking into consideration the floor structure on the first floor, it is necessary to provide an environment in which even persons with disabilities using wheelchairs can live without feeling inconvenience.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic sectional view of a unit building according to the present invention.
In this embodiment, an example in which the present invention is applied to a two-story unit type building is shown.
[0019]
In FIG. 1, a unit type building 10 is a two-story building. A building body 3 is fixed on a foundation 1, and a sloped roof 2 is placed on the top of the building body 3. The building main body 3 is formed with a building unit 20 stacked in two upper and lower stages on both sides at a predetermined interval L1, and is formed in a substantially rectangular plane as a whole.
[0020]
The building unit 20 has a substantially rectangular parallelepiped frame (framework) 23 in which the upper and lower ends of the columns 21 are joined by beams 22 as a basic structure. The column 21 and the beam 22 are each made of a square steel pipe or a steel material having a C-shaped cross section, and are joined and integrally assembled by welding in a factory. Adjacent or stacked building units are coupled to each other by bolting or the like via a shear plate (connection plate) not shown.
[0021]
In the interval L1 portion of the unit type building 10 , a construction structure 30 which is a planar structure is arranged so that the upper surface of the floor plate 24 of the second floor of the building unit 20 forms the same surface. Further, the floor structure 50 is disposed at the first floor position of the interval L1 portion of the unit type building 10, and the ceiling structure 70 is disposed at the ceiling position of the second floor.
[0022]
The unit type building 10 is configured such that a floor is formed on the upper surface of the planar structure 30 and a ceiling is formed on the lower surface so that the upper and lower floors of the interval L1 portion are used as living rooms. The planar structure 30 includes a plurality of, for example, four connecting beams 31A and 31B, a plurality of joists 32 respectively installed on the facing surfaces on the indoor side of the connecting beams 31A and 31B, and these joists. And a floor plate 34 stretched on the upper surface of 32. Each connection beam 31A, 31B is arranged with a space in the depth direction of the building, and has joint plates 311 at both ends, and is fixed to the frame 23 of the building unit 20 via the joint plates 311. The
[0023]
A plurality of joists 32 are arranged approximately at equal intervals, substantially parallel to each of the connection beams 31A and 31B in a substantially perpendicular direction. The joist member 32 is formed of a steel material having a C-shaped cross section, and both ends thereof are attached to the connecting beams 31A and 31B by bolting or the like. The floor board 34 is fixed on the joist member 32 by a method such as screwing to form a floor surface continuous with the floor board 24 on the second floor of the building unit 20.
