WOODEN CONSTRUCTION BEAM JOINT STRUCTURE
To provide wooden construction beam joint structure comprising fall prevention structure excellent in an external appearance.SOLUTION: Wooden construction beam joint structure 1 comprises columns 2 including junctions 6, a wooden beam 3 including vertical grooves and horizontal grooves provided at end surfaces in an extension direction, tendons 4 imparting prestress to the wooden beam 3, and horizontal steel plates 5 rushing into the horizontal grooves. Since the vertical groove is opened to an undersurface, and the shape combining the vertical groove and the horizontal groove shows T-shaped view from the lateral side. The junction 6 includes a protruding part 9 rushing into the vertical groove, and the protruding part 9 includes a steel plate orthogonal to a width direction of the wooden beam 3. Even when the tendons 4 are cut in earthquake, the wooden beam 3 does not fall since the protruding parts 9 support the wooden beam 3 through the horizontal steel plates 5, and the wooden beam 3 is prevented from being damaged by bearing capacity of the protruding parts 9 since the bearing capacity of the protruding parts 9 is dispersed by the horizontal steel plates 5 and is applied to the wooden beam 3. Since the protruding parts 9 are thin and are hard to see from underside, the wooden construction beam joint structure has an excellent external appearance.SELECTED DRAWING: Figure 1
【課題】外観の良い落下防止構造を備えた木造梁接合構造を提供する。【解決手段】木造梁接合構造１は、接合部６を含む柱２と、延在方向の端面に設けられた縦溝及び横溝を含む木造梁３と、木造梁３にプレストレスを与える緊張材４と、横溝に突入する水平鋼板５とを備える。縦溝は下面にも開口しており、側方から見ると縦溝及び横溝が組み合わさった形状はＴ字状をなす。接合部６は、縦溝に突入する突出部９を含み、突出部９は、木造梁３の幅方向に直交する鋼板を含む。地震時に緊張材４が切断しても、突出部９が水平鋼板５を介して木造梁３を支持するため、木造梁３は落下せず、突出部９の支持力が水平鋼板５によって分散されて木造梁３に加わるため、突出部９の支持力によって木造梁３が損傷することが防止される。突出部９が細くて下方から見えにくいため、外観が良い。【選択図】図１
