Description

The present invention relates to an upper floor entrance structure of a unit house.

(Conventional technology) A unit house is a box-shaped, housed unit of a fixed size that can be transported and has finished inside and outside, which is manufactured in a factory in advance, and is transported to a plurality of construction sites. It is assembled with a house.

In recent years, this unit house has been gradually and widely adopted because it is a standardized house having a short construction period and high dimensional accuracy.

However, this unit house has some restrictions in its structure because the house unit is pre-produced in a factory.

The upper floor entrance structure of the unit house is also one of the restrictions.

That is, conventionally, the entrance is usually provided on the first floor, but recently, as represented by an apartment, the entrance is often provided on the second floor or higher.

In the case where a unit floor is provided on the first floor in this unit house, as described in Japanese Patent Publication No. 54-13687, the floor beam is cut, and the entrance wall is provided at a position lower than the floor beam.
Explaining in detail with reference to FIG. 2, the skeleton of the housing unit includes four floor beams 101 connected in a rectangular shape, four ceiling beams 103 also connected in a rectangular shape, and these floor beams 103. It consists of a beam 101 and four pillars 102 connected to the corners of the ceiling beam 103. When the entrance is provided, a part of the floor beam 101 is cut off, and a space between the entrances is provided in the back.

Even if the floor beams are cut in this way, there is no need to worry about the strength because there is a foundation immediately below.

However, in the case of the upper floor, since there is no foundation, the floor beams cannot be cut due to the strength, and as described in Japanese Utility Model Publication No. The entrance soil was set up on the floor beams.

(Problems to be Solved by the Invention) However, as described above, if the floor between the entrances on the upper floor is provided on the floor beams of the upper-floor housing unit, the floor is also provided on the same floor beams. The height difference between the upper surface of the entrance soil and the upper surface of the upper floor was small, and dust between the entrance soil easily moved on the floor, which was unpleasant.

Therefore, the present invention has solved such a problem in a unit house, and has increased the difference in height between the entrance floor of the upper floor and the floor of the upper floor without cutting the floor beams of the upper floor housing unit as in the conventional case. The purpose is to provide an entrance structure.

(Means for Solving the Problems) The present invention has been made to solve the above problems and achieve the above object, and has pillars provided at four corners and a ceiling provided between the pillars. By a beam and a floor beam, in a unit house in which a plurality of house units constituting a framed structure are vertically stacked, the lower-floor house unit includes:
It has a housing unit which includes a staircase going up to the upper floor and a staircase hall connected to the upper part of the staircase going up to the upper floor and supported by a supporting beam bridged to the opposing ceiling beam. Bridge the support beam to the opposite floor beam of the upper floor housing unit placed directly above the built-in lower floor housing unit, so that the upper surface of this support beam is lower than the upper surface of the floor beam of the upper floor housing unit, Both ends of this support beam are fixed to the floor beam of the upper-floor housing unit, and an entrance space is provided on the support beam. Is what they do.

(Operation) In the present invention, a support beam is provided in addition to a normal floor beam so that the upper surface of the support beam is lower than the upper surface of the floor beam of the upper-floor housing unit. The space between the entrance lands is lower than the floor provided on the floor beam located higher than the support beam.
