以上のような本実施形態によれば以下の効果がある。
(1)柱10及び梁12A,12B,13A,13Bから略直方体状の骨組み14が形成された建物ユニット31〜34を左右に複数並べて施工されるとともに隣り合う建物ユニット31〜34の互いに近接する梁の少なくとも一部が欠損されたユニット式建物1の補強に用いられる補強梁6を、隣り合う建物ユニット31〜34の欠損部3Aと交差する交差梁310,320,330,340の裏面側に欠損部3Aを跨いで配置される梁本体61を有する構成とし、この梁本体61を内部に中空部を有する断面矩形とした。そのため、補強梁6が隣り合う建物ユニット31〜34の略直線上に配置された交差梁310,320,330,340の長手方向に沿って配置されており、かつ、その形状が内部に中空部を有する断面矩形とされているため、欠損部3Aを有する複数の建物ユニット31〜34の補強を強固かつ確実に行うことができる。その上、補強梁6は、その上面が交差梁310,320,330,340の上面と同じあるいは低く形成されているので、補強梁6の高さが建物ユニット31〜34の上面を超えることがないから、1階部分を構成する建物ユニット31,32を並べて配置した後、これらの建物ユニット31,32の上に2階部分を構成する建物ユニット33,34を施工する際に、補強梁6が邪魔となることがない。従って、ユニット式建物1の施工を安全に行うことができる。
According to the present embodiment as described above, the following effects are obtained.
(1) A plurality of building units 31 to 34 each having a substantially rectangular parallelepiped frame 14 formed from columns 10 and beams 12A, 12B, 13A and 13B are arranged side by side and adjacent building units 31 to 34 are close to each other. The reinforcing beam 6 used for reinforcing the unit type building 1 in which at least a part of the beam is lost is placed on the back side of the cross beams 310, 320, 330, and 340 that intersect with the missing part 3A of the adjacent building units 31 to 34. It was set as the structure which has the beam main body 61 arrange | positioned ranging over the defect | deletion part 3A, and this beam main body 61 was made into the cross-sectional rectangle which has a hollow part inside. Therefore, the reinforcing beam 6 is arranged along the longitudinal direction of the cross beams 310, 320, 330, and 340 arranged on a substantially straight line of the adjacent building units 31 to 34, and the shape is hollow inside. Therefore, the plurality of building units 31 to 34 having the missing portion 3A can be reinforced strongly and reliably. In addition, since the upper surface of the reinforcing beam 6 is formed to be the same as or lower than the upper surfaces of the cross beams 310, 320, 330, and 340, the height of the reinforcing beam 6 may exceed the upper surfaces of the building units 31 to 34. Therefore, after the building units 31 and 32 constituting the first floor portion are arranged side by side, when the building units 33 and 34 constituting the second floor portion are constructed on these building units 31 and 32, the reinforcing beam 6 is provided. Will not get in the way. Therefore, construction of the unit type building 1 can be performed safely.
(2)接合プレート64の他端縁は天井梁に設けられた欠損部3Aと交差する交差梁310,320,330,340の上面に接合されているから、梁本体61と建物ユニット31〜34の交差梁310,320,330,340とが接合プレート64を介して互いに接合されることになる。そのため、梁本体61と交差梁310,320,330,340とを近接配置させることができ、その結果、梁本体61と交差梁310,320,330,340との連結を強固なものにできる。
(3)接合プレート64の取付位置を天井梁に交差する交差梁310,320,330,340と梁本体61との上面としたので、接合プレート64を取り付ける作業を行う際に接合プレート64の上面が開放される状態となるので、接合プレート64の取付作業を容易に行うことができる。
(2) Since the other end of the joining plate 64 is joined to the upper surface of the cross beams 310, 320, 330, and 340 that intersect the missing portion 3A provided on the ceiling beam, the beam body 61 and the building units 31 to 34 are joined. The cross beams 310, 320, 330, and 340 are joined to each other via the joining plate 64. Therefore, the beam main body 61 and the cross beams 310, 320, 330, and 340 can be disposed close to each other. As a result, the connection between the beam main body 61 and the cross beams 310, 320, 330, and 340 can be strengthened.
(3) Since the attachment position of the joining plate 64 is the upper surface of the cross beam 310, 320, 330, 340 that intersects the ceiling beam and the beam main body 61, the upper surface of the joining plate 64 is used when attaching the joining plate 64. Since the state is opened, the attachment work of the joining plate 64 can be easily performed.
(4)梁本体61の下部を支持する支持ブラケット68が建物ユニット31〜34の柱10に取り付けられているから、補強梁6を支持ブラケット68及び柱10の双方で確実に支持できるので、補強梁6が誤って建物ユニット31〜34から外れることがない。さらに、補強梁6にかかる力が支持ブラケット68を介して柱10に伝達されるため、補強梁6の補強効果をより向上させることができる。 (4) Since the support bracket 68 that supports the lower portion of the beam main body 61 is attached to the column 10 of the building units 31 to 34, the reinforcement beam 6 can be reliably supported by both the support bracket 68 and the column 10, so that the reinforcement The beam 6 is not accidentally detached from the building units 31 to 34. Furthermore, since the force applied to the reinforcing beam 6 is transmitted to the column 10 via the support bracket 68, the reinforcing effect of the reinforcing beam 6 can be further improved.
(5)梁本体61は互いに開口部を対向させて接合した一対の断面コ字形の梁部材62,63から形成されるから、中空部を有する断面矩形の梁本体61を簡易な方法で実現することができ、そのため、補強梁6の製造を容易なものにすることができる。 (5) Since the beam body 61 is formed by a pair of U-shaped beam members 62 and 63 joined with the openings facing each other, the beam body 61 having a hollow section and having a rectangular section is realized by a simple method. Therefore, the manufacture of the reinforcing beam 6 can be facilitated.
(6)支持ブラケット68は、梁本体61の梁部材63の下面を支持するプレート部68Aと、このプレート部68Aの両側に接合され柱10の側面に固定された略三角形の支持片部68Bと、柱10の側面に溶接等で取り付けられ支持片部68Bが両側に固定された背板部68Cとを備えた立体形状としたので、支持ブラケット68の強度を大きなものにできる。その結果、補強梁6に大きな力がかかっても、支持ブラケット68で確実に筋することができる。 (6) The support bracket 68 includes a plate portion 68A that supports the lower surface of the beam member 63 of the beam body 61, and a substantially triangular support piece portion 68B that is joined to both sides of the plate portion 68A and fixed to the side surface of the column 10. Since the three-dimensional shape includes the back plate portion 68C attached to the side surface of the column 10 by welding or the like and the support piece portions 68B fixed to both sides, the strength of the support bracket 68 can be increased. As a result, even if a large force is applied to the reinforcing beam 6, the support bracket 68 can be surely streaked.
(7)交差梁310,320,330,340を短辺天井梁12Bや短辺床梁13Bに補強材35を取り付けた構成としたので、建物ユニット31〜34自体の強度を大きなものにすることができる。 (7) Since the cross beams 310, 320, 330, and 340 have the configuration in which the reinforcing material 35 is attached to the short-side ceiling beam 12B and the short-side floor beam 13B, the strength of the building units 31 to 34 themselves is increased.
