Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an L-shaped building unit having columns and beams, and a unit-type building using the L-shaped building unit.

[0002]

2. Description of the Related Art As shown in FIG.
Is a plurality of lower-floor building units 1 previously produced in a factory.
1. Upper floor building unit 12 and top floor building unit 1
It is built by combining 3 mag on site.
As shown in FIG. 6, these building units 11 to 13 have four pillars 15 erected at four corners and these pillars 15.
A frame 18 having four upper beams 16 and lower beams 17 for connecting between upper ends and between lower ends of the frame is provided, and a ceiling surface material, a floor surface material, an inner wall, an outer wall, and the like are attached to such a skeleton 18. Are formed in a substantially box shape. Note that a plurality of ceiling beams 19 are bridged between the upper beams 16 and a plurality of joists 20 are bridged between the lower beams 17. Pillar 15
The upper beam 16 and the lower beam 17 are connected to the upper beam 16 and the lower beam 17 by, for example, welding to form a rigid joint, and a strength frame 25 is formed by these members 15 to 17.

[0003] By the way, a diagonal line limit that defines a height limit of a building in a city planning area is defined, and it is said that the height of a building cannot exceed a certain diagonal line due to the diagonal line restriction. . The oblique line restriction includes road oblique lines, adjacent oblique lines, north oblique lines, and the like. But,
Since a general unit-type building combines box-shaped building units vertically and horizontally, it tends to have a rectangular parallelepiped shape as a whole. In this case, as shown in FIG. May conflict with each other.

[0004] In order to avoid such a diagonal line restriction P, for example, there is a unit type building 30 having a shape shown by diagonal lines in FIG. That is, in FIG. 5, three upper-floor building units 12 are provided on the upper surface of the five lower-floor building units 11 arranged side by side, and one upper-floor building unit 13 is provided on the upper surface of these upper-floor building units 12. Is provided. The upper-floor building unit 12 is retracted left and right by one building unit with respect to the lower-floor building unit 11.
Is the building unit 1 on the left and right with respect to the upper building unit 12.
It is arranged to retreat by each individual. That is, the overall shape is a pyramid-shaped shape.

[0005]

However, in the pyramid-shaped unit-type building 30, although the oblique line restriction P can be avoided, each step, that is, the lower floor 11 'and the upper floor 1
2 ′ and the number of load-bearing frames 25 on the top floor 13 ′ are different. Here, when counting the number of load-bearing frames 25 in FIG. 5, 10 are provided on the lower floor 11 ′, 6 are provided on the upper floor 12 ′, and two are provided on the top floor 13 ′. The difference in the number of load-bearing frames 25 on the floor is large. Therefore, there is a large difference in the magnitude (proof strength) of the force that can withstand the external force in the horizontal direction, and as a result, there is a problem that the balance of the whole building is deteriorated.

SUMMARY OF THE INVENTION An object of the present invention is to provide an L-shaped building unit and an L-shaped building unit capable of avoiding oblique line restriction, reducing the difference in proof stress between floors, and improving the balance of the whole building. The object of the present invention is to provide a unit-type building using a computer.

[0007]

An L-shaped building unit 1 according to a first invention of the present invention will be described with reference to the drawings.
As shown in FIG. 2, a wall frame 2 formed by connecting upper ends of a pair of pillars 15 with an upper beam 16 and connecting lower ends thereof with a lower beam 17, and a floor frame orthogonal to the wall frame 2. The floor frame 3 includes a first lower beam 17 ′ arranged in parallel with the lower beam 17, and a second lower beam 17 ′ connecting both ends of the first lower beam 17 ′ and lower ends of the columns 15.
It is characterized by being formed including the lower beam 17A.

In the above, the size of the L-shaped building unit is not limited, and the wall frame and the floor frame may each be a vertically long or horizontally long rectangle, or may be a square. In addition, the height of the column of the wall frame and the length of the second lower beam of the floor frame are not limited, and when both are equal, when the length of the column is longer, and when the length of the column is shorter, etc. Applicable to both.

In the present invention, since the L-shaped building unit is constituted by the wall frame and the floor frame, a normal box-shaped unit constituting a unit-type building is formed by using the wall frame as a bearing frame. It can be installed on the upper floor adjacent to the building unit, so that the number of load-bearing frames can be increased even when many box-shaped units cannot be juxtaposed. Can be reduced. Therefore, the difference in proof stress between floors can be reduced, and the balance of the whole building can be improved. Also, since there is no projection inside the L-shaped building unit facing the wall frame and floor frame, by arranging this L-shaped building unit on the diagonal line restriction side such as the north diagonal line, the strength of each floor is reduced. A unit-type building that can avoid oblique line restriction while reducing the difference can be provided. ,

A feature is that the length dimension of A is substantially the same as the short side dimension of the building unit. According to the present invention, when an L-shaped building unit is combined with a normal building unit, the first lower beam may be aligned with the long side of the building unit and the second lower beam may be aligned with the short side of the building unit. It is easy and easy to install, contributing to shortening the construction period of a unit building.

As shown in FIGS. 2 and 3, a unit-type building according to a fifth aspect of the present invention is a unit-type building 30 'using the L-shaped building unit 1 according to any one of the first to fourth aspects of the present invention. The L-shaped building unit 1 is configured to be retreated by at least one building unit 12 on the upper surface of a plurality of lower-floor building units 12 arranged side by side.

In the above, either the long side or the short side of the building unit may be retracted, both sides of the building may be retracted, or only one side may be retracted.
In the present invention as described above, even if the building unit is retracted, the L-shaped building unit is placed on that portion, and the wall frame of the L-shaped building unit is the load-bearing frame. The number can be increased, and the difference from the number of load-bearing frames of the building units on the lower floor can be reduced. Therefore, the difference in proof stress between floors can be reduced, and the balance of the whole building can be improved. Also, since the inside of the L-shaped building unit is open and has no protrusions, the L-shaped building unit is arranged on the diagonal line restriction side such as the northern diagonal line, for example, to reduce the difference in proof stress on each floor and restrict diagonal lines. Can be a unit-type building that can also avoid the problem.

As shown in FIG. 2, the unit type building according to the sixth aspect of the present invention is a lower building balcony 5 having a balcony floor member 6 having the L-shaped building unit 1 according to the fifth aspect mounted on a floor frame thereof. It is characterized by having. According to the present invention, since the L-shaped building unit is a vault balconi, it is possible to avoid a diagonal line restriction, improve the balance of the whole building, obtain a wide balconi, and change It can be a unit-type building with a sharp outline.
