BEAM JOINT CONSTRUCTION

PURPOSE:To increase vertical strength of beam joint construction by forming reinforcing sections as a unit together with vertical sections and horizontal sections in parallel with extensional directions of the vertical sections and horizontal sections, and connecting a first beam to a second beam at right angles. CONSTITUTION:In parallel with extensional directions of vertical sections 16 and horizontal sections 17a and 17b reinforcing sections 18a and 1 8b are integrated with vertical sections 16 and horizontal sections 17a and 17b. Or, a plurality of vertical sections 16 are provided, and edges of the vertical positioned on a first beam 11 side are fixed thereto. For that purpose, vertical deflection in a coupling metal fixture 15 is lightened, vertical deflection in a second beam 14 is allowable by portion of deflection. According to the constitution, in the case deflection in the whole beam structure falls within an allowable range to be set, it is not necessary that strength of the second beam 14 is increased, and cost increase of members can be avoided.
