[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building unit, and more particularly to a building unit having a frame structure used as a unit building.
[0002]
[Prior art]
As a building unit for a unit building produced at the factory, a framework structure is made up of pillars arranged at the four corners and floor beams spanned between the lower parts of adjacent pillars and both ends rigidly joined to each pillar, Building units with a ceiling panel on top are known.
[0003]
In the conventional building unit, the position of the upper surface of the ceiling panel is lower than the upper surface of the pillar, and when the protective sheet is hung directly on the building unit at the time of shipment, a recess is formed, and rainwater accumulates in the recess. Therefore, a temporary roof beam (field edge) is handed over the ceiling panel of the building unit, a temporary roof plywood is installed on the ceiling panel, and the product is shipped with a protective sheet hung so that rainwater does not collect on the protective sheet. ing.
[0004]
In addition, the conventional building unit has a type in which the four corners of the ceiling panel are fixed to the upper part (pillar) of the column. The ceiling of the ceiling panel is fixed with a hole attached to each of the ceiling panel and the column head. This is done by aligning the holes of the mounting bracket and driving rivets (see Japanese Patent Laid-Open No. 10-2018).
Furthermore, the conventional building unit does not have a structure capable of adjusting the ceiling height, and a gypsum board is directly attached to the unit connecting portion without adjusting the height of the ceiling surface.
[0005]
[Problems to be solved by the invention]
By the way, in the conventional building unit, the temporary roof beam is passed on the ceiling panel and the temporary roof plywood is installed on the ceiling panel so that rainwater does not collect on the protective sheet at the time of shipment as described above. On the other hand, since the temporary roof beams and the temporary roof plywood have already been removed as collected items at the time of installation, in the state where only the protective sheet is hung, such as when the construction is suspended, the protective sheet is depressed and rainwater is accumulated. For this reason, at the time of work after rainy weather, there is an inconvenience that rainwater collected in the depression of the protective sheet must be drained using a hose or the like.
[0006]
Moreover, because the stigma fixing of the ceiling panel in the conventional building unit is performed by driving the rivets together with the holes of the mounting bracket with holes attached to each of the ceiling panel and the stigma as described above, There is a problem that the work of aligning the holes of the mounting bracket is difficult, and the support of the ceiling panel is not stable until the rivet is driven, and the workability is poor.
[0007]
Furthermore, in the conventional building unit, it is not a structure that can adjust the ceiling height, and the gypsum board is pasted as it is to the unit connecting part, so there is a possibility that a step will occur on the ceiling surface, In addition, since the steel-made ceiling beam and the floor beam on the upper floor are in contact with each other, there is an inconvenience that a metal contact sound such as rattling occurs when walking on the upper floor.
[0008]
The present invention was made to solve the above-described problems, does not require a temporary roof beam or temporary roof plywood, does not collect rainwater in the recess of the protective sheet during installation, and fixes the top of the ceiling panel It is an object of the present invention to provide a building unit that is excellent in workability and can finely adjust the ceiling height with good workability, and a unit building that connects the building units.
