Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an upper floor entrance structure of a unit house.

(Prior art) A unit house is a box-shaped house of a certain size that can be transported.
In addition, housing units with finished interiors and exteriors are produced in advance at a factory, and a plurality of housing units are transported to a construction site and assembled on site to form a housing.

The second type of unit housing is characterized by a short construction period and standardized housing with good dimensional accuracy, so it has been increasingly widely adopted in recent years.

However, since the housing units are pre-produced in a factory, there are limitations to the structure of this unit housing.

The upper floor entrance structure of unit housing is also one of the constraints.

That is, conventionally, the entrance was usually provided on the first floor, but recently, entrances are often provided on the second or higher floors, as typified by apartments.

When installing an entrance dirt floor on the first floor of this unit housing,
As described in Japanese Patent Publication No. 54-13687, the floor beams were cut to provide an entrance dirt floor at a position lower than the floor beams. To explain in detail with reference to FIG. 2, the frame of the housing unit consists of four floor beams 101 connected in a rectangular shape, ceiling beams 103 connected in four rectangular shapes, and these floor beams 101 connected in a rectangular shape. It consists of a beam 101 and four columns 102 connected to the corners of a ceiling beam 103. When an entrance is provided, a part of the floor beam 101 is cut and an entrance earthen floor is provided behind this.

Even if the floor beam is cut in this way, there is no need to worry about its strength because the foundation strength is directly below it.

However, in the case of upper floors, there is no foundation, so for strength reasons, it is not possible to cut the floor beams. An entrance dirt floor was built on top of the floor beams.

(Problem to be solved by the invention) However, as described above, if the entrance earthen floor of the upper floor is installed on the floor beam of the upper floor housing unit, the floor is also installed on this same floor beam, so the upper floor The height difference between the upper surface of the entrance dirt floor and the upper surface of the floor of the upper floor became smaller, making it easier for dust, etc. on the entrance dirt floor to move onto the floor, which was unpleasant.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve this problem in a unit house and provide an entrance structure in which the difference in height between the entrance earthen floor on the upper floor and the floor on the upper floor is increased.

(Means for Solving the Problems) The present invention has been made to solve the above problems and achieve the above objects. In a unit house with an entrance dirt floor, a support beam is bridged between the opposing ceiling beam of this lower floor housing unit, both ends of this support beam are fixed to the ceiling beam of the lower floor housing unit, and the support beam is An earthen entrance floor for the upper floor will be provided above.

In the present invention, in addition to the support beam, a stair hall support beam may be provided on the ceiling beam of the same lower floor housing unit, and a stair hole for the upper floor may be provided on this stair hole support beam.

(Function) In general, unit housing is assembled by placing the upper floor housing unit on top of the lower floor housing unit.

Therefore, naturally, the ceiling beam of the lower floor housing unit is at a lower position than the floor beam of the upper floor housing unit.

In the present invention, in addition to the normal beams, support beams are fixed to the ceiling beams of the lower floor housing unit, and the entrance earthen floor for the upper floor is provided on top of this, so the entrance earthen floor provided on the support beams is ,
It will be lower than the floor installed on the floor joists of the upper floor residential units.

In the present invention, a support beam is provided on the ceiling beam of a housing unit on the lower floor and an entrance hall is provided on the ceiling beam, and a staircase hall support beam is provided on the ceiling beam of the same lower floor housing unit and an entrance hall is provided on the ceiling beam. , when entering and exiting from the entrance dirt floor to the stairway hall,
There are no floor beams of the upper floor housing units between the stairway hall and the entrance earthen floor, so you can get there without having to step over tall obstacles such as floor beams.

(Example) FIG. 1 is a sectional view showing one embodiment of the upper floor entrance structure of the present invention.

In FIG. 1, 1 is a ceiling beam of a first floor residential unit.

2 is the floor beam of the second floor residential unit.

A support beam 31 is bridged, welded, and fixed to an opposing ceiling beam on the first floor (not shown).

Reference numeral 32 denotes a stair hall support beam, and this stair hall support beam 32 is provided on the ceiling beam 1 of the first floor housing unit.

33 is a small beam bridged between the stair hall support beams 32, and 34 is a spacer that fills the gap between the support beams 31 and the stair hall support beams 32.

Reference numeral 4 designates an entrance earthen floor, which is provided on a support beam 31, and consists of a plywood flooring material 41 and a floor finishing material 42 made of a vinyl chloride resin sheet. 43 is a steel door frame. 7
is a door, and this door 7 is attached to a door frame 43.

6 is the floor of the second floor, and this floor 6 is provided on the floor beam 2 of the second floor residential unit. Further, an entrance stile 61 is provided at the end of the floor 6 on the entrance side, and a board 62 is provided between this entrance stile 61 and the entrance earthen floor 4.

8 is a stair hole, which is provided on the stair hole support beam 32 and the small beam 33.

9 is a staircase.

Next, the construction method and function of this unit house will be explained.

First, a first floor housing unit and a second floor housing unit are manufactured in a factory.

When manufacturing a second floor housing unit, inside this second floor housing unit there will be an entrance door frame 43, a second floor floor 6, an entrance frame 61,
The plate material 62 is installed at the factory. The first floor housing unit has a support beam 31, an entrance dirt floor 4, a stair hall support beam 32,
Attach the small beam 33, spacer 34, stair hole 8, and stair 9. Once the first floor housing unit and second floor housing unit are manufactured in this way, they are transported to the construction site, and the second floor housing unit is placed on top of the first floor housing unit.
After assembling and finally installing the front door, the unit house is completed.

In this way, the completed unit house has 6 floors on the second floor.
Since it is located at a higher position than the entrance earthen floor 4, dust etc. of the entrance earthen floor does not move to the floor.
