Abstract

A glulam construction method suitable for relatively small-sized wooden buildings is disclosed. Each joint metal has its plate portion and pipe portion joined in a racket-like shape. At an end of a column, a slit is formed to open at a column end surface and to extend in a column width direction. At an abutment part in a beam abutting on the column end surface, mortises penetrating in a beam depth direction are formed at two positions appropriately spaced from each other in a span direction. Each joint metal has its pipe portion fitted in the corresponding mortise and has its plate portion fitted in the slit of the column. The joint metals are fixed in the column and the beam by drift pins or bolts and thereby establish rigid connection therebetween.

Claims4

Dependent claims

A connection structure for glued laminated timber, in which a column and a beam made of medium or small dimension glued laminated timber are rigidly connected by a pair of joint metals such that the beam is connected on top of the column,

wherein each of the joint metals comprises a plate portion and a pipe portion that are joined together in a racket-like shape, each of the plate portion and the pipe portion having a fixing hole for a drift pin or a bolt,
wherein the column is provided with a slit at an end thereof, the slit opening at a column end surface and extending in a column width direction, and the beam is provided with mortises at an abutment part thereof that abuts on the column end surface, the mortises penetrating in a beam depth direction and arranged at two positions that are appropriately spaced from each other in a span direction, and
wherein the pair of joint metals is fixed in the column and the beam by having the pipe portion of each joint metal fitted in corresponding one of the mortises and by having the plate portion of each joint metal being fitted in the slit of the column, and thereby establishes rigid connection between the column and the beam.
