Description

  The present invention relates to a unit building provided with an overhang portion above an entrance corner formed by two building units, and relates to a unit building that effectively uses the entrance corner as a space below the overhang portion. Is.

  A unit construction method is known in which unit buildings are constructed in a short period of time by transporting multiple box-shaped building units manufactured in advance at the factory to the construction site and assembling multiple adjacent building units at the building site. ing.

  In such a unit construction method, an upper-floor building unit may be placed overhanging a lower-floor building unit.

  For example, in Japanese Patent Publication No. 8-14151 (Patent No. 2110058), an upper building unit 42A having a long girder direction is placed on a lower building unit 41A having a short girder direction as shown in FIG. The overhang portion 46 is formed, and the overhang portion 46 is supported by a pair of overhang portions 45 that overhang from the end face of the lower floor building unit 41A.

  In FIG. 14, adjacent to the upper and lower building units 41A and 42A, a lower building unit 31B having the same digit length as the upper building unit 42A and an upper building unit 42B mounted thereon are added. An example is shown in which a unit building is constructed that has a corner 43 as a lower space disposed below the overhang 46.

  Next, when constructing a unit building, a building unit having an entrance space may be required, and an example of such a building unit is shown in FIG.

  In the figure, a first lower-floor building unit 48 having a entrance space 51 is placed on a foundation 47, and a second lower-floor building unit 49 is disposed adjacent to the first lower-floor building unit 49. On the first and second lower floor building units 48 and 49, first and second upper floor building units (not shown) are arranged, respectively.

  An entrance space 51 is formed in the first lower-floor building unit 48, and an entrance 52 is disposed on the back side of the entrance space 51. Thus, when providing the entrance space 51 and the entrance 52 in a building unit, the exclusive 1st lower-floor building unit 48 and the foundation 47 for it are required.

  However, in the conventional unit building shown in FIG. 14, when trying to construct a unit building having the corner portion 43, the overhanging portion 45 provided in the lower floor building unit 41 </ b> A has a corresponding upper floor building unit 42 </ b> A. Since only the overhang portions 46 are individually supported, when the lower-floor building unit 31B and the upper-floor building unit 42B are arranged adjacent to each other, there is nothing between the support structures of the adjacent overhang portions 46. There will be no cooperative relationship.

For this reason, when a load in the horizontal direction acts on the unit buildings 41A, 42A and 41B, 42B, the upper and lower building units 41A are displaced by the downward movement of the overhang portion 46 due to the load (self-weight) of the overhang portion 46. , 42A and the adjacent upper and lower lower floor building units 31B, 42B are liable to cause horizontal misalignment.

  Next, in the conventional unit building shown in FIG. 15, in order to provide the entrance space 51 and the entrance 52 in the unit building, a dedicated first lower floor building unit 48 and foundation 47 having the entrance space 51 and the entrance 52 respectively. There was a problem that required.

  For this reason, the number of parts for the first lower-floor building unit 48 is increased, which causes a problem that the production efficiency of the unit building 50 is reduced and the cost of the unit building is increased.

  Furthermore, it is desirable that the entrance space 51 can be arranged at an arbitrary position and orientation of the first lower floor building unit 48 and that the size of the entrance space 51 is also arbitrary. Therefore, it is difficult to arbitrarily cope with problems such as the position and size of the entrance space 51.

  Accordingly, a first object of the present invention is to provide a unit building that prevents horizontal displacement between adjacent building units by reliably holding the load due to the weight of the overhang portion of the upper floor building unit. It is in.

  Moreover, the 2nd objective of this invention is to provide the unit building which can utilize effectively the corner part comprised by the adjacent building unit.
