Description

Description: TECHNICAL FIELD The present invention relates to a unit housing configured by combining a plurality of housing units formed in a rectangular parallelepiped shape in a factory in advance. Specifically, it relates to a unit house in which the upper unit is larger than the lower unit, that is, an overhung unit house.

[Background technology]

In recent years, in a building such as a house, a plurality of housing units manufactured in advance in a rectangular parallelepiped shape in a factory are transported to a construction site, and then these are combined to form a living room.

In this type of unit housing, when an overhung unit housing is constructed by placing an upper floor unit having a lower surface shape larger than the upper surface shape of the lower floor unit on the upper surface of the lower floor unit, the upper housing of the lower floor unit is simply In the structure in which the floor unit is mounted, the amount of downward bending of the overhang portion of the upper floor unit is large.

As a method of reducing this, the sectional shape of the floor beam of the upper floor unit may be increased. However, this leaves the problem that standard units cannot be used. Therefore, conventionally, the following method has been adopted.

As shown in FIG. 3, the first method is to provide a pillar 6 directly below the two pillars 5 of the overhang portion 4 of the upper floor unit 3 mounted on the upper surface of the lower floor unit 1, and use the pillar 6 to support the pillar 6. This structure supports the load of the overhang portion 4 of the upper floor unit 3.

In the second method, as shown in FIG. 4, the four pillars of the upper floor unit 3 are made to correspond to the four pillars 2 of the lower floor unit 1, respectively, and the overhang portion 4 of the upper floor unit 3 is changed into a chianti beam. The structure is composed of 7 and columns 8.

[Problems to be Solved by the Invention]

However, the conventional method described above has the following problems.

First, in the first method, since the pillar 6 is located in front of the lower floor unit 1, there is a problem that not only the appearance is impaired, but also the use of the overhanging portion 4 below is restricted.

In the second method, when a plurality of upper floor units 3 are connected to form a room, for example, as shown in FIG.
When a room is composed of the three upper floor units 3A to 3C, there is a problem that the adjacent pillars 5 (the shaded pillars 5 in FIG. 5) of the upper floor units 3A to 3C interfere with each other.

Here, an object of the present invention is to provide a unit house that solves all such conventional problems.

[Means for solving the problem]

Therefore, in the present invention, a lower floor unit formed in a rectangular parallelepiped shape including four columns and beams connecting the upper ends and the lower ends of the four columns, and the lower floor unit mounted on the upper surface of the lower floor unit. A total of four pillars, two of which are arranged in positions corresponding to the two pillars of the lower floor unit and the other two of which are overhanging with respect to the upper surface of the lower floor unit. An upper floor unit formed in the shape of a rectangular parallelepiped including beams connecting the upper ends and the lower ends of the two pillars, and the four pillars of the upper floor unit and the two lower floor units that do not correspond to each other. An overhanging member is provided which projects from the upper end of the pillar in the overhang direction of the upper floor unit and receives the lower ends of two pillars arranged at positions where the upper floor unit overhangs. .

Here, the projecting member may be supported by a cane that is obliquely projected from the pillar of the lower floor unit. in this case,
The pillar-side connecting end and the protruding member-side connecting end of the cane may be fixed by welding or the like, or may be connected by pin joining.

[Operation] Since the lower floor unit is provided with an overhanging member for receiving the two pillars arranged at a position where the upper floor unit overhangs, the overhanging member of the upper floor unit is also affected by the overhanging member. Since the load of the hang portion can be shared and supported, the amount of downward bending of the overhang portion can be reduced. By the way, compared with the case where the upper floor unit is simply placed on the lower floor unit, the bending amount can be reduced to about half.

This means that the floor beams of the upper floor units do not have to be particularly large, so standard units can be used. Needless to say, since the pillar as in the past is unnecessary, the use below the overhang portion is not restricted,
Further, even when a plurality of upper floor units are connected to form a room, the pillars of adjacent units do not interfere.

In particular, the overhanging member that receives the lower ends of the two pillars arranged in the overhanging position of the upper floor unit is from the upper ends of the two pillars of the lower floor unit that do not correspond to the four pillars of the upper floor unit. Since it is projected in the overhang direction of the upper floor unit, the load of the overhang portion received at the tip can be released to the foundation via the column, and the load on the beam of the lower floor unit can be reduced. That is, compared with the case where the projecting member is fixed to the beam of the lower floor unit, the load applied to the beam of the lower floor unit can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, 11 is a lower floor unit and 21 is an upper floor unit mounted on the upper surface of the lower floor unit 11.

Each of these units 11 and 21 has four pillars 12A to 12D, 22A to 22D arranged at the four corners and four ceiling beams 13A to which the upper ends of the pillars 12A to 12D and 22A to 22D are connected. 13D, 23A ~ 23D
And the lower ends of the columns 12A to 12D and 22A to 22D are connected to each other 4
The floor beams 14A to 14D and 24A to 24D have a rectangular parallelepiped shape. Small beams 15, 16, 25, 26 are provided at regular intervals between the ceiling beams 13A, 13B, 23A, 23B facing each other and between the floor beams 14A, 14B, 24A, 24B. In addition, braces 17 and 18 are stretched in an X shape at diagonal positions on the upper surface.

Here, in the upper floor unit 21, among the four pillars 22A to 22D, the two pillars 22C and 22D are the pillars 12C and 12D of the lower floor unit 11.
And the remaining two columns 22A and 22B are arranged at positions overhanging with respect to the upper surface of the lower floor unit 11. That is, the lower surface shape of the upper floor unit 21 is formed in a rectangular shape which is longer in the longitudinal direction than the upper surface shape of the lower floor unit 11.

Further, the pillars 12A, 12 are provided on the upper side surface of the lower floor unit 11 (upper side surface on the side where the upper floor unit 21 overhangs).
Chianti beams 18A, 18B as projecting members that project from the upper end of B in the longitudinal direction of the ceiling beams 13A, 13B and receive the two columns 22A, 22B arranged at the positions overhanging the upper floor unit 21. Is provided. A beam is inserted between the tip ends of the cantilever beams 18A and 18B, and a brace 19 is laid in an X shape in a rectangular portion surrounded by the beams. Further, both ends of the canes 20A and 20B are obliquely inserted by welding between the cantilever beams 18A and 18B and the columns 12A and 12B.

Therefore, according to this embodiment, the two pillars 22A, which are arranged at the position where the upper floor unit 21 overhangs, on the upper side surface of the lower floor unit 11 (the upper side surface where the upper floor unit 21 overhangs), Since the Chianti beams 18A and 18B that receive the 22B are provided, the load of the overhang portion of the upper floor unit 21 can be dispersed and received by the tip portions of the Chianti beams 18A and 18B and the upper end surfaces of the columns 12A and 12B. it can.

Therefore, the amount of downward bending of the overhang portion of the upper floor unit 21 can be reduced. By the way, the lower floor unit
The amount of bending can be reduced to about half as compared with the case where the upper floor unit 21 is simply placed on top of 11. This means that the floor beams 24A and 24B of the upper floor unit 21 do not need to have a particularly large cross-sectional shape, and thus a standard unit can be used.

Further, since the canes 20A and 20B are obliquely inserted between the tips of the cantilever beams 18A and 18B and the columns 12A and 12B, the canes 20A and 2B are
The pillars 12A and 12B can also receive the load applied to the tip ends of the cantilever beams 18A and 18B via 0B. Therefore, the cross-sectional shapes of the cantilever beams 18A and 18B themselves do not need to be so large, and the connecting portions with the columns 12A and 12B do not have to be fixed so strongly.

In addition, since a pillar as in the conventional case is not required, the use of the lower part of the overhang portion is not restricted, and even when a plurality of upper floor units are connected to form one room, Adjacent pillars do not get in the way. Therefore, the degree of freedom in design is not limited.

In the above embodiment, the lower surface shape of the upper floor unit 21 is formed in a rectangular shape that is longer in the longitudinal direction than the upper surface shape of the lower floor unit 11. However, as shown in FIG. The lower surface shape of 21 may be a rectangular shape that is longer in the width direction than the upper surface shape of the lower floor unit 11.

Further, in the above-mentioned embodiment, the both ends of the canes 20A and 20B are provided with the pillar 12
Although it is welded to the A, 12B and the catty beams 18A, 18B, pin joining may be used.

Further, although depending on the length of the overhang portion of the upper floor unit 21, if the cantilever beams 18A and 18B can be firmly coupled to the columns 12A and 12B, the canes 20A and 20B need not be specially provided.

〔The invention's effect〕

As described above, according to the present invention, it is possible to reduce the number of distorted beams in the overhang portion of the upper floor unit without increasing the size of the floor beam of the upper floor unit and without requiring columns or the like. Furthermore, the pillars do not interfere even when a plurality of upper floor units are connected to form a room or the like.
