(a) In the lower floor building unit 10A, as a reinforcing means 30 in the middle part of the ceiling beam 13 on which the column base of the front column 22 of the upper floor building unit 20A is mounted, A closing plate 40 fitted between the upper and lower flanges was provided. Thereby, the shear strength and torsional strength of the ceiling beam 13 can be reinforced only by fitting the closing plate 40 in the space in the cross section of the C-shaped steel constituting the ceiling beam 13 of the lower floor building unit 10A. Therefore, the ceiling beam 13 can be reinforced without restricting the use of the wall surface and ceiling surface of the lower floor building unit 10A.
(b)上述(a)の補強手段30を構成する閉塞プレート40が、プレート本体41の上下端部から側方に突出する上下の突片42を備え、上下の突片42を前記天井梁13を構成するC形鋼における上下のフランジの内面に嵌合してなるものとすることにより、閉塞プレート40の嵌着組込み性を向上できる。   (b) The closing plate 40 constituting the reinforcing means 30 of the above (a) includes upper and lower projecting pieces 42 projecting sideways from the upper and lower ends of the plate body 41, and the upper and lower projecting pieces 42 are connected to the ceiling beam 13. By fitting to the inner surfaces of the upper and lower flanges in the C-shaped steel constituting the structure, the fitting and assembling property of the closing plate 40 can be improved.
(c)上述(a)の補強手段30が、上述(a)の閉塞プレート40に固定されて該天井梁13に直交するユニット内側方向へ延在する受けプレート50とからなり、上階建物ユニット20Aの桁側床梁21が受けプレート50に搭載されるものとした。上階建物ユニット20Aの桁側床梁21を上記受けプレート50に搭載したから、下階建物ユニット10Aの上記天井梁13にねじりモーメントが発生しないものになり、その天井梁13を一層補強できる。   (c) The reinforcing means 30 of the above (a) includes a receiving plate 50 fixed to the closing plate 40 of the above (a) and extending inwardly of the unit perpendicular to the ceiling beam 13, and an upper floor building unit. It is assumed that the 20A girder floor beam 21 is mounted on the receiving plate 50. Since the girder floor beam 21 of the upper building unit 20A is mounted on the receiving plate 50, no torsional moment is generated in the ceiling beam 13 of the lower building unit 10A, and the ceiling beam 13 can be further reinforced.
(d)上述(c)の補強手段30を構成する受けプレート50が、前記閉塞プレート40にボルト接合される取付板部51と、取付板部51の両側縁部に直交配置されて溶接される2枚の側板部52と、2枚の側板部52の上縁部に載架されて溶接される受け板部53とからなるものとすることにより、受けプレート50の取付性、上階建物ユニット20Aの桁側床梁21の搭載性を向上できる。   (d) The receiving plate 50 constituting the reinforcing means 30 of the above (c) is welded by being arranged orthogonally to the mounting plate portion 51 that is bolted to the closing plate 40 and both side edges of the mounting plate portion 51. By comprising two side plate portions 52 and a receiving plate portion 53 that is mounted on and welded to the upper edge portion of the two side plate portions 52, the mounting property of the receiving plate 50, the upper building unit The mountability of the 20A girder floor beam 21 can be improved.
(e)下階建物ユニット10Aの上にセットバック配置された上階建物ユニット20Aを搭載するユニット建物100において、下階建物ユニット10Aの天井梁13を上述(a)〜(d)により補強できる。   (e) In the unit building 100 that mounts the upper floor building unit 20A that is set back on the lower floor building unit 10A, the ceiling beam 13 of the lower floor building unit 10A can be reinforced by the above-described (a) to (d). .
図7は、前述のユニット建物100を構成する下階建物ユニット10Aの妻側天井梁13の中間部の補強手段30の変形例を示すものである。この変形例の補強手段30は、前述の閉塞プレート40のみからなり、受けプレート50を伴わないものである。この変形例によれば、前述の実施例による(a)、(b)、(e)の作用効果を奏する。   FIG. 7 shows a modification of the reinforcing means 30 in the middle part of the end-side ceiling beam 13 of the lower-floor building unit 10 </ b> A constituting the unit building 100 described above. The reinforcing means 30 of this modification consists only of the above-mentioned closing plate 40 and is not accompanied by the receiving plate 50. According to this modification, the effects (a), (b), and (e) according to the above-described embodiment are exhibited.
以上、本発明の実施例を図面により詳述したが、本発明の具体的な構成はこの実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。   The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention.
