Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type building in which a plurality of building units having a rectangular parallelepiped frame in which the upper and lower ends of four pillars are connected by beams are combined.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings constructed by combining a plurality of box-shaped building units manufactured in a factory at a building site have been used. As a building unit forming a unit type building, a building unit having a rectangular parallelepiped frame in which upper and lower ends of four pillars are connected by a ceiling beam and a floor beam is generally used. The frame of the building unit includes ceiling materials indicated by ceiling beams, floor materials supported by floor beams, interior materials such as partition walls for partitioning a room, and exterior wall goods formed of lightweight cellular concrete or the like. Assembled at the factory. According to such a unit-type building, in a factory, the work of assembling the interior material and the outer wall material to the building unit is performed in an improved manner, and after that, the building is completed only by performing the joining work of the building unit. Therefore, the work on the construction site is greatly reduced, and the merit that the construction work can be completed in a short time can be obtained.

[0003]

In the conventional unit-type building, the building units constituting the unit-type building are:
The strength of columns and beams is set assuming up to three stories. When trying to construct a four-story building or more with such a building unit, the height of the unit-type building increases, the outer wall surface receiving horizontal loads such as wind pressure becomes wider, and the horizontal load applied to the unit-type building increases. In addition, even if each of the building units constituting the unit-type building is uniformly displaced, since the displacement from the original position is larger as the unit-type building is higher, the building units arranged on the first and second floors include: A higher rigidity than before is required, and the conventional building unit has a problem of insufficient rigidity. Here, it is conceivable to improve the rigidity of the building unit by increasing the cross-sectional dimensions and wall thicknesses of the columns and beams that make up the framework of the building unit. In building units, columns and beams with large cross-sectional dimensions and wall thickness dimensions are over-specified.For building units with four or more floors and building units with three or lower floors, columns and beams with different cross-sectional dimensions and wall thickness are different. Since a beam is used, the manufacturing efficiency of the building unit is hindered.

As shown in FIG. 10, the applicant has provided a stud 91 at the center of the side surface along the long side direction, and the stud 91 has sufficient rigidity to form a four-story structure. A building unit 92 is proposed to be secured (Japanese Patent Application No. 9-242854). However, in such a building unit 92, if the upper and lower ends of the studs 91 are not rigidly connected to the beams 93, sufficient rigidity cannot be ensured. Since it is necessary to manufacture in a process different from the above, the problem of the manufacturing efficiency cannot be solved. In addition, since the stud 91 is provided at the center of the side surface of the building unit 92, there is a problem that it is difficult to secure a wide opening such as a sweep window.

An object of the present invention is to provide a unit-type building which can secure rigidity even in a four-story structure without impairing the manufacturing efficiency of the building unit.

[0006]

The present invention will be described with reference to the accompanying drawings.
Building unit with rectangular frame 56 connected by 55
A unit building 1 in which a plurality of units 10 to 40 are combined, and a sub-frame 4 forming a truss structure along a column 51 arranged at a corner 5 of the unit building 1 in plan view.
Is provided with the reinforced building units 11, 21 and 22 provided with. In the present invention, since the columns forming the framework of the reinforced building unit are reinforced by the subframes forming the truss structure, the rigidity of the reinforced building unit is increased. If the reinforced building unit is arranged so that the reinforced columns are arranged at the corners of the unit-type building, the rigidity of the columns arranged on both side edges of the outer wall portion of the unit-type building is improved, and the wind pressure is increased. Sufficient proof stress against horizontal load such as Moreover, since the subframe of the truss structure can be attached to the frame of the building unit by pin bonding, if the subframe is attached to the frame after assembling the frame of the building unit into a rectangular parallelepiped, the conventional building unit assembly process Assembling is possible,
Does not hinder the manufacturing efficiency of building units. In addition, since the pillars are directly reinforced with subframes, the reinforced building unit does not require reinforcing members such as studs located in the center of the side, so a wide opening including the center can be easily formed. It can be secured.

[0007] In the above, it is preferable that the two sub-frames are arranged in an L-shape in plan view with the pillar arranged at the corner of the unit building interposed therebetween. In this way, the bending of the columns arranged at the corners of the unit building is suppressed in the two directions in which the subframes are arranged, and both of the two outer wall portions intersecting at the corners of the unit building, Sufficient strength against horizontal load such as wind pressure can be secured, and the rigidity of the unit building can be secured with the minimum number of subframes.

The reinforced building unit has a rectangular shape having a short side and a long side having different lengths, and is disposed at one end of the long side of the reinforced building unit at a corner of the unit-type building. It is preferable that the column to be provided is provided, and the subframe is also provided on the column side provided at the other end of the long side. In this way, when forming a large living room inside, by combining a plurality of building units having a rectangular planar shape, it becomes possible to form a living room in which no pillar is exposed inside, and a planar rectangular building unit When the columns are arranged vertically and horizontally, the number of subframes will increase in the long side direction where the number of pillars is smaller than the short side direction, so sufficient reinforcement against the horizontal load applied to the long side direction of the unit type building will be sufficient. As a result, not only the rigidity of the entire unit-type building is secured, but also the rigidity balance can be secured.

Further, it is preferable that the unit-type building has a four-story structure, and the reinforced building unit is provided on a first floor portion and a second floor portion. In this way, if reinforced building units are provided on the first and second floors of a unit building, and regular building units without subframes are provided on the third and higher floors, the weight of the third and higher floors will be reduced. In addition, horizontal displacement of building units on three or more floors is allowed, and horizontal load is concentrated on the root part of the column, etc., unlike securing rigidity throughout the vertical direction of the column. Instead, the overall distribution of the horizontal load is achieved. For this reason, the rigidity balance of the entire unit-type building is ensured while securing sufficient rigidity in the unit-type building, and the durability of the framework of the unit-type building is ensured even in the case of a four-story building.

[0010] Further, it is preferable that the unit-type building has a sloped roof, and the living room on the fourth floor is provided in the back of the cabin of the sloped roof. In this way, if the living room on the fourth floor is provided on the back of the roof hut, the height of the unit building will be lower than when the building is a four-story building with only a rectangular parallelepiped building unit and a sloped roof is formed on it ,
When building a four-story building in an area with height restrictions, it is possible to sufficiently prevent the height of a unit building from increasing.

1, 21 and 22 are provided, and normal building units 12, 23, 30, and 40 without the subframe 4 are provided on the third floor and above, so that the weight of the third floor and above can be reduced. The building units 30, 40 on the third floor and above are allowed to be displaced in the horizontal direction, so that the rigidity is secured for the entire column 51 connected from the first floor to the fourth floor. The horizontal load can be dispersed as a whole without the horizontal load being concentrated on the like. For this reason, the rigidity balance of the entire unit-type building 1 is ensured while securing sufficient rigidity in the unit-type building 1, and the unit-type building 1 has a four-story structure.
The durability of the frame can be ensured. Besides,
The second-floor part of the unit-type building 1 has a smaller number of subframes 4 than the first-floor part, and the stiffness of the frame gradually decreases upward from the first-floor part. The rigidity balance of the entire building 1 is secured, and the durability of the framework of the unit building 1 can be secured.

Furthermore, since the living room on the fourth floor is formed in the back of the sloping roof 3 provided in the unit-type building 1, the unit can be formed as compared with the case where the inclined roof is formed on the living room on the fourth floor. Since the height of the unit-type building is reduced, an increase in the height of the unit-type building 1 can be sufficiently suppressed when constructing a four-story building in an area where the height is restricted.
