PROBLEM TO BE SOLVED: To provide a beam structure of a building, in which the position change of a plurality of beams with respect to a girder can be preferably performed.SOLUTION: A building unit 20 includes ceiling girders 22 and ceiling beams 25 laid between a pair of ceiling girders 22 extending parallel to one another. In the building unit 20, a pair of ceiling beams 25 are connected by a connection plate 32, and a beam unit 31 is formed by including the pair of ceiling beams and the connection plate 32. The connection plate 32 connects the ends of the pair of ceiling beams 25 to one another. The end of the beam unit 31 enters a groove of the ceiling girder 22, while the connection plate 32 is overlaid on a web of the ceiling girder 22. Connection plate holes are formed in the connection plate 32, girder holes are formed in the web of the ceiling girder 22, the beam unit 31 is provided at a position where the connection plate holes communicate with the girder holes, and a bolt is inserted into each of the connection plate holes and the girder holes, thereby fixing the connection plate 32 to the ceiling girder 22. |
