PROBLEM TO BE SOLVED: To provide a horizontal member junction structure such that pipes and the like can be laid in a ceiling space crossing a hung beam without spoiling the flexural strength of the hung beam even when a ceiling member is arranged in the vicinity to a lower surface of the hung beam.SOLUTION: A junction between a receiving beam 11 arranged at an upper part of a wall body 10 and a hung beam 12 supported by the receiving beam 11 has a recessed cut 16 formed at a lower-end corner portion of an end 12a of the hung beam 12 joined to the receiving beam 12. Pipes and the like are arranged at the recessed cut 16. A beam height h2 of the hung beam 12 is larger than a beam height h1 of the receiving beam 11, and the recessed cut 16 has a cut upper-end portion 16a cut more upward than from a lower-end face 11a of the receiving beam 11. The cut upper-end portion 16a is fitted with a wall surface material 21 constituting a wall body 20 by fitting an upper-end edge 21a to a lower side face of the receiving beam 11 without cutting the upper-end edge 21a. |
