Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a top panel of a building unit used for waterproofing and scaffolding the building unit.

[0002]

BACKGROUND ART A building unit has four columns at four corners and a frame composed of an upper beam and a lower beam connecting the upper ends and lower ends of these columns with a floor material, a ceiling material, etc. attached in advance at a factory. Various kinds of outfitting are performed, and further, an outer wall and the like are attached to form a substantially box shape. Such building units are usually once placed in a stockyard of a factory and then brought to a construction site where they are combined to construct a unit building.

By the way, when the building unit is placed in a stockyard of a factory, or when the building unit is assembled at a construction site, it may start to rain. Conventionally,
As a waterproof measure when the building unit is placed in the stockyard of the factory, for example, a substantially triangular-pyramidal mounting tool is mounted as a dedicated upper panel on the building unit, and a waterproof sheet is put on the mounting panel. Also, when building units are combined at the construction site, plywood that serves as a support for the waterproof sheet is placed on the beam of the ceiling beam of the building unit with the brace of the ceiling beam submerged, and the waterproof sheet is removed from this plywood. The whole building unit is covered via the ceiling beam to protect the inside of the building unit, especially various outfitting, from rain. Also, the plywood used when combining building units is
It is also used as a scaffold.

[0004]

However, the conventional top panel used for waterproofing when placing a building unit in a stockyard is dedicated to each building unit and is not versatile, so various sizes are required. Sano's building unit cannot be flexibly dealt with. Further, for example, a substantially triangular pyramid-shaped top panel cannot be used as a scaffold.

In a conventional plywood used for waterproofing at a construction site, since the plywood is located at a position lower than the upper surface of the ceiling beam, the brace or plywood is used as the waterproof sheet unless the waterproof sheet is strongly pulled from the periphery of the ceiling beam. Adheres to the upper surface of
A dent having a ceiling beam as an edge is formed. Therefore, there is a problem that rain accumulates in the depression. Further, since rain collects in the depression, the waterproof sheet may be damaged, or the sheet may be damaged by a protruding nail or a sharp corner, and the accumulated rain may leak from the damaged part. Further, if the rain accumulates in the depression, it is difficult to remove the sheet after the rain has stopped. Further, conventionally, since the plywood is placed on the small beam of the ceiling beam, the brace has to be dipped to remove the plywood, and the brace is an obstacle, so the removal of the plywood is troublesome.

The object of the present invention is to cope with various building units, to cover a top surface with a waterproof sheet without collecting rainwater, to easily attach the building unit, and to use it as a scaffolding. The purpose is to provide a top panel for a building unit.

[0007]

Therefore, a first aspect of the present invention comprises a face member detachably mounted on the upper surface of a ceiling beam of a building unit, and a reinforcing member provided on the lower surface of the face member. The reinforcing member is placed on a beam provided on the ceiling beam, and has a notch for inserting a brace provided on the upper surface of the building unit. It is what

A second aspect of the present invention is that the face material of the top panel is
It is configured by arranging a plurality of facets, and the reinforcing member is provided for each of these facets to form a top panel of a building unit.

[0009]

In the first aspect of the invention as described above, the upper panel composed of the face member and the reinforcing member is provided on the upper surface of the building unit by mounting the reinforcing member on the beam of the ceiling beam. The brace is inserted and placed on the upper surface of the ceiling beam of the building unit. Since the top panel is provided on the top surface of the ceiling beam, even if the waterproof sheet is put on the ceiling panel, the sheet does not dent, and therefore rainwater does not collect. Further, since the top panel may be placed on the top surface of the ceiling beam, it can be easily attached, and the above-mentioned objects can be achieved by these.

According to the second aspect of the invention, the upper panel is formed by arranging a plurality of facets each provided with a reinforcing member, and such an upper panel is placed on the upper surface of the ceiling beam.
