BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhang structure for a unit house, and can be used to overhang a housing unit on an upper floor of a unit house.

0002

BACKGROUND ART In general, housing units are produced with wall materials, ceiling materials, floor materials, etc. attached to the frame in advance at a factory. Then, such a plurality of housing units are combined at a construction site, and a unit housing is constructed by further combining roof units and the like.

[0003] In such unit housing, for reasons such as wanting to secure a large floor area for the upper floor housing units, unit housing units with a structure that protrudes outward from the lower floor housing units, that is, unit housing units with an overhang structure, are built. It may happen.

By the way, in a typical unit house, an upper floor housing unit is placed directly above a lower floor housing unit. This is due to the vertical load transmitted from the columns of the upper floor housing unit.
This is because the ceiling beams of normal lower floor units do not have the strength.

[0005] For these reasons, the overhang structure of the above-mentioned housing units has also been limited, as shown in FIGS. 6, 7, and 8.

That is, in FIG. 6, the upper floor housing unit 62 is made longer than the lower floor housing unit 61, and the two are combined to form a unit housing unit 60 with an overhang structure.
will be built. In addition, in FIG. 7, as described in FIG. 6, the upper floor housing unit 72 is made longer than the lower floor housing unit 71, and the overhang part of this upper floor housing unit 72 is supported by support columns 73. This is a unit housing 70. Furthermore, the unit house 80 in FIG.
, an upper floor housing unit 82 of the same size as this unit 81 is placed on a lower floor housing unit 81, and an overhang of a cantilever-supported Chianti beam structure 83 is connected to this upper floor housing unit 82. be.

[0007]

[Problems to be Solved by the Invention] However, the conventional overhang in FIG.
A special upper floor housing unit 62 that is longer than the length of the housing unit 62 must be made, which is troublesome because the process is different from that of a normal unit. Furthermore, if the overhang of the upper floor housing unit 62 is too long, the weight of the upper floor unit 62 becomes heavy, and as a result, a load is applied to the lower beam of the long side of the upper floor unit 62.
There is a risk that the lower beam may bend.

With the overhang in FIG. 7, there is no problem that the lower beam in FIG. 6 is bent, but
A support column 73 for supporting one end of the overhang with the support beam 73 is separately required, which requires extra cost. Further, since the support pillar 73 is provided near the lower floor housing unit 71, there is a problem that it becomes a hindrance to traffic.

In the overhang shown in FIG. 8, the overhang is cantilevered, so if the Chianti beam 83 is made longer, the weight of the overhang becomes heavier, and there is a risk that a large load will be applied to the Chianti beam 83 and the beam may be deformed. There is. To prevent this, special measures such as making the beams and columns thicker are required, which increases costs, so when installing an overhang using Chianti beam 83 in a regular housing unit, the length of the overhang is limited. It was something.

Furthermore, in the overhang shown in FIG. 8, the overhang using the Chianti beam 83 must be attached afterwards to the housing unit 82 that has been produced in advance at a factory, which requires extra steps such as the installation process and the finishing process after installation. This required several steps and was expensive.

Furthermore, as shown in FIGS. 6 to 8, conventional overhang structures overhang in the direction of the long side beams of the housing unit, but do not overhang in the direction of the short side beams. This is because the dimension in the short side beam direction is limited due to transportation restrictions. but,
There was a desire for a unit house with overhang not only in the direction of the long side beams but also in the direction of the short side beams.

[0012] An object of the present invention is to provide an overhang structure for a unit house, which has a simple structure and can easily and largely overhang the housing unit in either direction of the long side or the short side, or in both directions. There is something to do.

[0013]

[Means for Solving the Problems] The present invention provides an overhang structure for a unit house in which a lower floor housing unit is mounted with an upper floor housing unit that projects from the lower floor housing unit and these units are combined. A through-beam having a length longer than the lower-floor housing unit is provided between the first-floor housing unit and the upper-floor housing unit, and the upper-floor housing unit is attached onto the through-beam. It has a hang structure.

[0014]

[Operation] According to the present invention, a through beam is provided on the upper surface of the lower floor housing unit, and the upper floor housing unit is installed on the through beam. A through beam has a simple structure that is longer than at least one of the long and short sides of the lower floor housing unit, and since the upper floor housing unit is placed on such a through beam, it is easy to install. . Additionally, as mentioned above, the through-beam can be made longer on either the long or short sides of the lower floor unit, making it possible to overhang the housing unit in the short side direction as well, thereby achieving the above purpose. be done.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an overall front view and an overall side view of a unit house 1 using the overhang structure of the unit house of the present invention. As is clear from these figures, this embodiment assumes a case where the housing unit is overhanged in the short side direction.

According to these figures, a plurality of first floor housing units 3, which are lower floor housing units, are installed on the foundation 2,
A through beam 4 is provided on the upper surface of this first floor housing unit 3. A plurality of second floor housing units 5, which are upper floor housing units, are mounted on the upper surface of the through beam 4, and central and outer roof units 6, 7 are further mounted on the second floor housing units 5.
A unit house 1 is constructed by attaching a roof unit 8 consisting of a roof unit 8, an eaves unit 9, etc.

[0017] As the through beam 4, H-beam steel, channel steel,
A single material such as a square steel pipe is used, and is connected to each housing unit 1 by bolting or welding after being guided by a pillar pin or the like. There is at least one connection point near the end of each unit house. Therefore, in the case of bolting, a plurality of bolts are used for one housing unit.

As shown in FIGS. 1 and 3, the through-beam 4 is formed in such a length that the second-story residential unit 5 overhangs both sides of the first-floor residential unit 3 by one piece in its short side direction. ing. The bridge is constructed so as to be located directly above the pillars and beams of the first floor housing unit 3.

However, in this embodiment, the through beam 4 is provided over three rows of first floor housing units 3 and five rows of second floor housing units 5, so it is very long. Because of this, it is difficult to transport and handle, so it is divided into parts. In this case, as shown in FIG. 3, the longitudinal direction of the through-beam 4 may be divided into two, for example, by a dividing portion D. Further, after the division, the through-beams 4 may be pin-joined to each other on site, or may be rigidly joined.

Next, the procedure for assembling the unit house of this embodiment will be explained. Multiple one-story residential units 3, foundation 2
Place them one after another on the setting plate installed above, and then securely fix them with anchor bolts.

Next, guide pins such as pillar pins are attached to the plurality of first floor housing units 3, and the through beams 4 are placed at predetermined positions. This first floor housing unit 3 and through beam 4
and are fixed by upper and lower joint bolts or welding.

Guide pins 10 such as column head pins are attached to predetermined positions on the upper surface of the through-beam 4, and these pins 10
A plurality of second-story residential units 5 are sequentially placed on the upper surface of the through-beam 4 by being guided by the guide. Thereafter, the through-beam 4 and the second-story housing unit 5 are fixed using upper and lower joint bolts, welding, or the like.

Next, guide pins such as column head pins are attached to the upper surface of the second-story residential unit 5, and the roof unit 8 is attached by being guided by these pins.Then, the eaves unit 9, etc. are sequentially attached, and the unit house with an overhang structure is completed. 1 will be built.

According to this embodiment as described above, the following effects can be obtained. That is, first floor and second floor residential units 3 and 5.
In both cases, a regular housing unit can be used as is, so there is no need to make the overhanging unit extra long.

Furthermore, since the second-story residential unit 5 is mounted and fixed on the through-beam 4, there is no need for the support pillars 73 to support the overhang, which eliminates the cost and eliminates the need for the support pillars 73 to support the overhang. It will never happen.

Furthermore, the through beam 4 is fixed to the upper surface of the first floor housing unit 3 and is configured to be able to sufficiently withstand the load of the second floor housing unit 5, and the load of the second floor housing unit 5 is distributed to the through beam 4. Therefore, the second floor residential unit 5
It is now possible to carry about the size of a single car, allowing for a long overhang.

Furthermore, in order to overhang the second floor housing unit 5, it is only necessary to place and fix the second floor unit 5 on the through beam 4 provided on the first floor housing unit 3, making installation easy. It is.

Furthermore, the through-beam 4 can be formed as a frame structure, extending also in the long side direction of the first-floor residential unit 3. In this way, it becomes possible to overhang the housing unit in both the long and short sides, including the overhang in the short side direction, which has not been done in the past.

It should be noted that the present invention is not limited to the above-described embodiments, but includes the following modifications.

That is, in the above embodiment, the through beam 4 was provided only between the first floor housing unit 3 and the second floor housing unit 5, but it may be provided as shown in FIG. 4. According to the figure, the through beam 4 is provided between the first floor housing unit 3 and the second floor housing unit 5, and is also provided on the upper surface of the second floor housing unit. According to this embodiment, in addition to the effects of the previous embodiment, it is possible to add the effect that the rigidity of the unit house 1 as a whole becomes even higher.

Furthermore, in the above embodiment, the first floor residential unit 3
Although the structure is such that the second-story residential unit 5 is placed directly above the through-beam 4, the structure is not limited thereto. For example, Figure 5
It may be done as shown in . That is, according to the figure, the second floor housing unit 5 is placed on the first floor housing unit 3 via the through beam 4, but the pillar 5A of the second floor housing unit 5 is positioned on the ceiling beam 3A of the first floor housing unit 3. It is listed as follows. According to this embodiment, the amount of overhang is smaller than in each of the embodiments described above, and in addition to the above-mentioned effects, it is possible to add the effect that it can be used when it is desired to adjust the amount of overhang.

Further, in the above embodiment, the first floor housing unit 3 and the through beam 4, and the through beam 4 and the second floor housing unit 5 are each fixed separately by upper and lower joint bolts or welding, but the present invention is not limited to this. After placing the through beam 4 on the first floor unit 3 and placing the second floor unit 5 on the through beam 4, the through beam 4 is passed from the lower beam of the second floor housing unit 5 to the ceiling beam of the first floor housing unit 3. The three parts may be integrally connected by upper and lower joint bolts that communicate with each other. According to this embodiment, in addition to the effects of the above-mentioned embodiments, it is possible to add the effect that the effort required to attach the through beam 4 and the second-story housing unit 5 is reduced.

Furthermore, in each of the embodiments described above, the through beam 4 is divided into two parts in the longitudinal direction of the through beam 4, but when there is only one or two first floor housing units 3, the through beam 4 may be short. It goes without saying that there is no need to divide the package if it is already completed and there is no problem in transporting it.

Further, in the above embodiment, the through-beam 4 is a long single-piece through-beam extending to the overhanging side, but these through-beams 4 may be connected to form an integrated framework structure. . In short, if the through beam 4 is formed on the top surface of the first floor housing unit 3 and is longer than at least one of the long side and short side direction of the first floor unit 3, and the second floor housing unit 5 is placed on top of it, good.

Further, although the above embodiment has been described as a two-story unit house, it can also be used for a three-story unit house. In this case, only the third floor may be overhanged, or both the second and third floors may be overhanged.

[0036] In addition, the specific structure and shape for carrying out the present invention may be other structures as long as the object of the present invention can be achieved.

[0037]

[Effects of the Invention] As explained above, according to the overhang structure of the unit house of the present invention, the structure is simple, and
There is an effect that a large overhang structure can be easily provided in either direction of the long side or short side of the housing unit, or in both directions.
