[0002]
[Background]
Conventionally, a unit type building constructed by connecting a plurality of box-shaped building units manufactured in a factory at a construction site has been used.
As a building unit forming this unit type building, one having a box-shaped frame in which upper and lower ends of pillars at four corners are connected by a ceiling beam and a floor beam is generally used. The frame has a ceiling surface material supported by the ceiling beam, an interior material such as a floor surface material supported by the floor beam and a partition wall partitioning the room, and an exterior material such as an outer wall formed of lightweight cellular concrete. It is assembled with.
According to such a unit-type building, after the building unit is manufactured by performing the attaching work of the interior material and the exterior material to the box-shaped frame in the factory, the building unit is simply transported to the site and the connecting work is performed. Since the building is completed, the work on the construction site is greatly reduced and the construction can be completed in a short period of time.
[0003]
On the other hand, in a unit type building (hereinafter referred to as a laminated unit type building) formed by stacking building units up and down, a large space without a pillar such as a large living room may be formed inside the lower building unit. is there. In this case, for example, one of the four pillars provided on the frame of a normal building unit is omitted to form a large space building unit, and the corner of the large space building unit is omitted. A large space is formed by bringing together the four.
[0004]
At this time, since one pillar is omitted, the rigidity of the large space building unit is reduced. Therefore, a normal two span is provided between the pillars arranged on both sides of the corner where the pillar is omitted. A reinforcing beam having a length of minutes is provided to compensate for the rigidity (see Japanese Patent Application Laid-Open No. 8-277580).
[0005]
[Problems to be solved by the invention]
According to the invention disclosed in Japanese Patent Application Laid-Open No. 8-277580, a corner where a column is omitted by connecting a reinforcing beam to the lower building unit or both the lower building unit and the upper building unit. Although the corners are reinforced, there is a possibility that the middle part of the reinforcing beam is bent because the load of the upper building unit acts on the ceiling beam of the lower building unit.
In general, in a laminated unit type building, when the lower building unit is formed of a large space building unit, even if the reinforcing beam is provided, the middle part of the reinforcing beam is lowered by the load of the building unit supported by the reinforcing beam. Bend. In particular, since the central portion of the reinforcing beam is located at the corner where the pillar of the large space building unit is omitted, the bending is maximized. As a result, the ceiling of the building unit for large spaces hangs down and the floor of the upper floor dents, which may require additional correction.
[0006]
An object of the present invention is to provide a unit type building that includes a reinforcing beam that forms a large space inside and suppresses the hanging of the center of the ceiling surface of the large space and the occurrence of a dent on the upper floor surface of the large space.

It is tightened with.
[0028]
The unit connection portion 742 of the end connection portion 74 is coupled to the first floor building unit 20B and the second floor building unit 30A, similarly to the unit connection portion 732 of the center connection portion 73.
Specifically, the positioning pin 45A of the stigma joining member 45 of the first-floor building unit 20B is inserted into the positioning hole 74A of the end connection part 74, and becomes the positioning hole of the pedestal joining member 46 of the second-floor building unit 30A.

It is tightened with 81B.
[0029]
Next, a procedure for assembling a large large space where no protrusions such as pillars 41 are present will be described.
First, the large space building unit 20B is manufactured at the factory in the same manner as the building units 20A and 30A and the reinforcing beams 70, and then transported to the building site. In order to prevent deformation of the large space frame 50 of the building unit 20B during transportation, provisional pillars (not shown) are provided in the corner portions 20D. The temporary column is detachably connected to the column base joining member 46 and the stigma joining member 45. Then, as shown in FIG. 9, the corner portions 20D of the four large space building units 20B are brought together and arranged adjacent to each other.
[0030]
After that, the reinforcing beam 70 is arranged between the columns 41 arranged in the corner portion 20C, and the positioning pin 45A of the stigma connection member 45 of the large space building unit 20B is inserted into the positioning hole 74A of the end connection portion 74. The position of the reinforcing beam 70 is determined. At this time, the unit connection portion 732 of the central connection portion 73 is located at a position higher by YX than the unit connection portion 742 of the end connection portion 74 with respect to the beam main body 71. Located slightly above 45.
[0031]
Then, the second floor building unit 30A is stacked on the large space building unit 20B. Then, the central connection portion 73 is pushed downward by the load of the second floor building unit 30A, that is, the central portion of the reinforcing beam 70 is bent, and the height positions of the unit connection portions 732 and 742 with respect to the second floor building unit 30A are changed. It becomes constant. When the central portion of the reinforcing beam 70 is elastically deformed and bent, an internal stress is generated in the reinforcing beam 70 with respect to the second-floor building unit 30A, and an upward force is applied to the central connection portion 73 with respect to the second-floor building unit 30A. A downward force is obtained at the end connection portion 74. Then, the load of the large space building unit 20B and the internal stress generated in the reinforcing beam 70 are substantially balanced at a position where the center connecting portion 73 is pushed down to a position where it substantially contacts the stigma joining member 45 of the corner portion 20D. In this state, the second floor building unit 30 </ b> A, the large space building unit 20 </ b> B, and the reinforcing beam 70 are connected and integrated by the fasteners 81. Thereafter, when the temporary pillar is removed, a large large space in which no protrusions such as the pillar 41 exist between the ceiling and the floor is formed.
[0032]
Therefore, according to this embodiment, there are the following effects.
(1) When the reinforcing beam 70 is coupled to the building units 20 </ b> B and 30 </ b> A via the end connection portion 74 and the central connection portion 73, the reinforcing beam is connected to the 2 through the end connection portion 74 and the central connection portion 73. Although the load of the floor building unit 30A is received, the column 41 in the central portion is omitted, and in this state, the floor beam 43 of the second floor building unit 30A and the ceiling beam 42 of the first floor building unit 20B are bent. According to the present invention, since the downward force with respect to the second floor building unit 30A is set at the end connection portion 74 and the upward force is set at the center connection portion 73, this upward force is set at the second floor building unit. The second floor building unit 30A is supported in balance with the load of 30A. Therefore, it is possible to form a large space inside, and to suppress the drooping of the center of the ceiling surface of the large space and the depression of the upper floor surface.
[0033]
(2) The height difference YX between the unit connection portion 732 of the center connection portion 73 and the unit connection portion 742 of the end connection portion 74 is equal to the deflection size of the center of the reinforcing beam generated by the second-floor building unit 30A. Since these unit connection portions 732 and 742 are connected to the building unit, the central connection portion 73 is pushed downward, that is, the central portion of the reinforcing beam 70 is bent downward to connect each unit. The height positions of the portions 732 and 742 with respect to the building units 20B and 30A are constant. In this state, the load of the second-floor building unit 30A and the internal stress generated in the reinforcing beam 70 are balanced. That is, when the central portion of the reinforcing beam 70 is elastically deformed and bent, an internal stress is generated in the reinforcing beam 70, and an upward force is obtained at the central connection portion 73 and a downward force is obtained at the end connection portion 74. It is possible to support the load of the second-floor building unit 30A.
Therefore, the necessary upward and downward forces can be easily obtained by calculating in advance without forming the reinforcing beam with a particularly rigid material.
[0034]
(3) Since the beam main body 71 is formed linearly, the beam main body 71 can be easily manufactured.
[0035]
(4) Since the connecting portion 72 is a plate-like material, the connecting portion 72 can be easily fixed to the beam main body 71 simply by forming a slit in the beam main body 71. Further, since the height positions of the unit connection portions 732 and 742 are adjusted by adjusting the height positions of the beam main body connection portions 731 and 741 of the connection portions 72, that is, the slits, the connection portions 72 are formed in a flat plate shape. The connecting portion 72 can be easily manufactured.
[0036]
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the above embodiment, the normal shear plate 60 is used for each connection portion 72 and the height positions of the beam main body connection portions 731 and 741 are set to the same height as the unit connection portions 732 and 742. The main body connection portions 731 and 741 may be formed at a height different from that of the unit connection portions 732 and 742 while keeping the height positions thereof constant.
Specifically, as shown in FIG. 10A, the central connection portion 73 is bent with respect to the unit connection portion 732 so that the beam main body connection portion 731 is positioned above the unit connection portion 732, and On the other hand, the end connection portion 74 is bent so that the beam main body connection portion 741 is positioned below.
[0037]
This also has the following effects in addition to the effects (1), (2), and (3) described in the previous embodiment.
(5) Since each connection part 72 is plate-shaped, each connection part 72 can be easily fixed to the beam body 71 simply by forming a slit in the beam body 71. In addition, since the height positions of the beam main body connection portions 731 and 741 of the connection portions 72, that is, the slits are constant, the beam main body 71 can be easily manufactured by continuous processing. At this time, it is possible to easily manufacture by changing the height positions of the unit connection portions 732 and 742 and the beam main body connection portions 731 and 741 of each connection portion 72 by bending.
[0038]
In the above embodiment, the beam body 71 is formed in a straight line, but the beam body may be bent so that the center of the axis is higher than the end. Specifically, as shown in FIG. 10 (B), the beam main body 71 is a cylindrical member having a rectangular cross section, and its axis is unit connection between the unit connection portion 732 of the central connection portion 73 and the end connection portion 74. In accordance with the difference in height dimension with the portion 742, it is formed by bending upward, and each connecting portion 72 is formed in a flat plate shape, and the height positions of the beam body connecting portions 731 and 741 are the beam body 71. It is formed at a certain height with respect to the axis line.
[0039]
This also has the following effects in addition to the effects (1) and (2) described in the previous embodiment.
(6) Since the beam main body 71 is bent in accordance with the height difference between the unit connection portions 732 and 742 of each connection portion 72, the height position of the beam main body connection portions 731 and 741 of each connection portion 72 is set to the beam main body. It can be formed at a constant height with respect to the 71 axis. Therefore, the beam main body 71 can be easily formed by continuous processing.

The load of the building unit can be supported.
[0042]
For example, if the difference in height between the unit connection part of the central connection part and the unit connection part of the end connection part is set equal to the deflection dimension of the center of the reinforcing beam caused by the upper building unit, the height of the unit connection part In the state where the position is substantially horizontal, the load of the upper building unit and the internal stress generated in the reinforcing beam are balanced.
Therefore, the necessary upward and downward forces can be easily obtained by calculating in advance without forming the reinforcing beam with a particularly rigid material.
[0043]
Claim 2 Since the beam main body is formed in a straight line, the beam main body can be easily manufactured.
[0044]
Claim 3 According to the unit type building described in (1), since the connecting portion is a plate-like material, the connecting portion can be easily fixed to the beam main body only by forming a slit in the beam main body. Also, because the height position of the unit connection part is adjusted by adjusting the beam body connection part of each connection part, that is, the height position of the slit, the connection part can be formed into a flat plate shape, and the connection part is manufactured. Can be easily done.
[0045]
Claim 4 Since each connection part is a plate-shaped material, each connection part can be easily fixed to a beam main body only by forming a slit in the beam main body. Moreover, since the height position of the beam main body connection portion, that is, the slit of each connection portion is constant, the beam main body can be easily manufactured by continuous processing. At this time, it is possible to easily manufacture by changing the height positions of the unit connecting portion and the beam main body connecting portion of each connecting portion by bending.
[0046]
