DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit building constructed by combining a plurality of box-like building units.

[0002]

2. Description of the Related Art In recent years, in order to increase the rate of industrialization and shorten the construction period at a construction site, a unit construction method in which a plurality of building units are manufactured in a factory in advance and these are combined at the construction site to construct a building has been used. ing. Building units
In general, a frame having a substantially rectangular parallelepiped shape having four pillars erected at four corners and beams connecting between upper ends and lower ends of these pillars is provided. Square steel having a square cross section is commonly used for the pillars constituting the skeleton (see Japanese Patent Application Laid-Open No. 10-8569). Such a pillar with a square cross section increases the size of one side of the square, that is,
Increasing the cross-sectional area allows it to withstand greater forces. Since the strength required for pillars of a building varies depending on its position in the building, unit-type buildings commonly use pillars sized according to the maximum force applied to the pillars.

[0003]

In this method, since all the columns are sized to withstand the maximum force, all the columns have a large cross-sectional area, that is, a large one. For this reason, when the building units are arranged side by side, pillars will be assembled at the portions where the corners of the building units are adjacent, and particularly, at the portion where the corners of the four building units are gathered, four pillars will be , The space occupied by the pillars in the building becomes large, and there is a problem that the internal space of the building cannot be used effectively. In addition, there is a strong demand for a lighter building unit in order to increase the height of the building and reduce transportation costs.However, since the pillars are relatively heavy due to the above-mentioned dimensions, the weight of the building unit must be sufficiently reduced. I couldn't.

[0004] It is an object of the present invention to provide a unit-type building capable of effectively utilizing the internal space of the building and achieving weight reduction.

[0005]

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described with reference to the drawings.
Is a unit-type building 1 configured by combining a plurality of columns and beams, wherein the building units are columns and beams 22, 23, 2
4, 25, comprising a first pillar 21 having a square cross section and a second pillar 41 having a rectangular cross section. It is characterized in that both the pillar and the second pillar are used.

[0006] In the present invention, since the pillars are composed of the first pillar having a square cross section and the second pillar having a rectangular cross section having relatively lower strength than the first pillar, each pillar in the building has The first and second pillars can be selectively used depending on the required strength. In other words, the first pillar is used for pillars where high strength is required in the building, and the pillars where rectangular cross-section pillars can maintain structural balance are better than the first pillars. If the second pillar having a small cross-sectional area is used, the space occupied by the pillar in the building can be reduced, and the internal space of the building can be used effectively. Further, since the second pillar having a smaller sectional area than the first pillar is used, the weight of the building unit can be reduced.

Further, the long side of the rectangular cross section of the second column is
It is desirable that the first column has the same length as one side of a square cross section. With this configuration, the second pillar can be smaller in cross-sectional area than the first pillar, that is, can be made thinner. Since the dimensions of the second pillar can be partially unified, design can be simplified.

In the above, it is preferable that at least the column to which the outer wall members 26 and 27 are attached is the first column. That is, the column to which the outer wall material is attached needs strength to support the outer wall material, and a horizontal force due to wind is applied. Therefore, sufficient strength can be secured by using the first column having a square cross section.

[0009] Further, the frame constituting the building unit is
When it is configured to have pillars erected at the four corners and beams connecting the upper and lower ends of these pillars, the pillars are arranged at the corners where a plurality of building unit corners gather. It is preferable that the pillar provided is a second pillar. In other words, in the portion where the columns are assembled, high strength is obtained by connecting the columns, so that the required strength can be secured by using the second column, and even if the columns are assembled, they can be stored in a relatively small space. be able to.

In the above, it is preferable that the frame is formed in a substantially rectangular parallelepiped shape, and that the long side of the rectangular cross section of the second column is parallel to the long side direction of the frame in plan view. That is, the horizontal force applied to the column is greater in the longitudinal direction of the skeleton than in the short side direction. In addition, the strength of the second column having a rectangular cross section with respect to the force in the horizontal direction is greater than the strength with respect to the force along the short side of the second column. For this reason, by arranging the second column so that the long side of the rectangular cross section is parallel to the long side direction of the skeleton, the strength corresponding to the magnitude and direction of the force applied to the column can be secured, While reducing the space and weight of pillars,
Appropriate strength is obtained.

Each of the building units 2 to 6 has a frame 20, 30, 40, 50 having a substantially rectangular parallelepiped shape (the frame of the upper floor building unit 6 is not shown). These skeletons 20-
Reference numeral 50 denotes four pillars 2 as shown in FIGS.
1, 41, the long side upper beam 22 and the short side upper beam 23 connecting the upper ends of these four columns 21, 41, and the length connecting the lower ends of the four first columns 21, 41. The lower side beam 24 and the shorter side beam 25 are included (only the frames 20, 40 are shown in FIGS. 3 and 4). Of these, pillar 2
Numerals 1 and 41 are made of a steel pipe or the like, and upper beams 22 and 23 and lower beams 24 and 25 are made of a channel steel having a U-shaped cross section. Such frames 20 to 50 include outer wall materials 26 and 2.
7 (see FIG. 2), an unillustrated inner wall material, floor material, ceiling material and the like are assembled.

As shown in FIG. 2, the frame 30 of the lower-floor building unit 3 provided with the recess 9 for the entrance is
Skeleton 20 including column 21 and beams 22 to 25 described above
The stud 31 is assembled to the stud 31.
It is provided upright at a portion corresponding to the concave portion 9. This skeleton 3
At 0, the outer wall members 26 and 27 are assembled along the stud 31 to form the concave portion 9, and the entrance door 32 is attached to the deep portion of the concave portion 9.

Each of the columns 21, 41 of such lower-floor building units 2 to 5 is either a first column 21 having a square cross section or a second column 41 having a rectangular cross section. That is, the pillars 21 and 41 of the lower-floor building units 2 to 5
Among them, the one to which the outer wall materials 26 and 27 are attached is the first pillar 21 having a square cross section, and the pillars arranged at each corner at the site where the corners of the four building units 4 and 5 gather. , Four are second pillars 41 having a rectangular cross section. Even if four pillars 21 are assembled, if at least one of the pillars 21 is attached with the outer wall material 27, all four pillars 21 are regarded as the first pillars 21. That is,
The building units 2 bundled together with the first pillar 21 to which the outer wall material 27 constituting the recess 9 of the building unit 3 is attached
The fourth column is a first column 21. The pillars 21 and the pillars 41 adjacent to each other between the building units 2 to 5 are connected to each other via a joining plate (not shown) arranged so as to cover the end faces.

In the frame 20 of the lower-floor building unit 2 constituting the lower-floor part 12A, as shown in FIG.
1 are all first columns 21 having a square cross section. Further, the frame 30 of the lower-floor building unit 3 having the concave portion 9 is one in which a stud 31 having a square cross section is erected between the upper side beam 22 and the lower side beam 24 of the frame 20 (FIG. 2). reference).

The frame 40 of the lower-floor building unit 4 is shown in FIG.
As shown in FIG. 5, one of the four pillars is a second pillar 41, and the remaining three pillars are a first pillar 21. The long side of the rectangular cross section of the second column 41 has the same length as one side of the square cross section of the first column 21. Thereby, the short side of the rectangular cross section of the second column 41 is shorter than one side of the cross section of the first column 21, and the cross sectional area of the second column 41 is smaller than the cross sectional area of the first column 21. Has become. Further, the strength of the second column 41 against the force in the horizontal direction is greater than the strength along the short side direction with respect to the force along the long side direction. It is arranged so that the side is parallel to the long side direction of the skeleton 40 in plan view. That is, the horizontal force applied to the column 41 is larger in the direction of the upper beam 22 and the lower beam 24 than in the direction of the upper beam 23 and the lower beam 25. Because it is larger than the force applied, the second pillar 41
The strength corresponding to the magnitude and direction of the force applied to the shaft can be secured.

As shown in FIG. 2, the lower-floor building unit 5 has two of the four pillars as second pillars 41 and the remaining two pillars as first pillars 21. , The second pillar 41
Are approximately the same as the frame 40 shown in FIG.

According to this embodiment, the following effects can be obtained. That is, the pillars of the lower floor portion 12 </ b> A are configured by the first pillars 21 having a square cross section and the second pillars 41 having a rectangular cross section having relatively lower strength than the first pillars 21. Since the first and second columns 21 and 31 are selectively used according to the strength required for the columns, the building 1
The space occupied by the pillars 21 and 41 can be reduced. That is, the first pillar 21 is used as a pillar of a portion where high strength is required in the building 1, and a second pillar having a smaller cross-sectional area than the first pillar 21 is used for a pillar not requiring high strength. Since 41 is used, the internal space of the building 1 can be used effectively. Also, as the pillars of the frameworks 40 and 50, the first pillar 21
In addition, since the second pillar 41 having a smaller cross-sectional area is used, the weight of the building units 4 and 5 can be reduced.

Further, since the long side of the rectangular cross section of the second column 41 is the same length as one side of the square cross section of the first column 21, the second column 41 is made larger than the first column 21. Since the cross-sectional area can be reduced, the space and the weight of the columns can be reliably reduced, and the dimensions of the first and second columns 21 and 41 can be partially unified, thereby facilitating the design.

The pillars to which the outer wall members 26 and 27 are attached need strength to support the outer wall members 26 and 27 and a horizontal force due to wind is applied. In the present embodiment, the outer wall members 26 and 27 are used. Since the pillar to which is attached is the first pillar 21 having a square cross section, sufficient strength can be secured.

In addition, since four pillars arranged at each corner are connected at a portion where the corners of the building units 4 and 5 are gathered, a high strength can be ensured. Although not required, in the present embodiment, all of these four columns are the second columns 41, so that sufficient strength can be ensured and the four columns 41 can be stored in a relatively small space. .

Furthermore, since the long side of the rectangular cross section of the second column 41 is parallel to the long side direction of the frames 40 and 50 in plan view, appropriate strength is achieved while saving space and weight of the column. Is obtained.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations capable of achieving the object of the present invention, and also includes the following modifications.
That is, in the above embodiment, one side of the square cross section of the first column 21 and the long side of the rectangular cross section of the second column 41 have the same length, but these may be different. However, in order to save the space of the columns, it is preferable to set the dimensions so that the cross-sectional area of the second column is smaller than the cross-sectional area of the first column.

In the above embodiment, one or two second columns 41 are used for the frame of the building units 4 and 5, but the type of the columns is appropriately selected according to the strength required for the columns in the building. For example, if high strength is not required for all pillars, all four pillars may be used as second pillars, and if only one pillar requires high strength, One of the four pillars may be the first pillar, and the remaining three pillars may be the second pillar.

In the above-described embodiment, the lower floor portion of the building is described. However, the first and second columns may be selectively used in the upper floor portion in the same manner. Furthermore, the arrangement of the building units is not particularly limited, and may be appropriately arranged in implementation, and the pillar to be used may be selected according to the arrangement.
