A system and method for creating a column for construction using bundled tube are provided. The column having a bottom portion, a middle portion, and a top portion. Each portion consists of a bundle of individual pillars, comprising a center pillar, a plurality of corner pillars, and a plurality of middle pillars. From the bottom portion of the column, addition pillars can be affixed on top of the pillars of the bottom portion, thus forming the middle and the top portion of the column. Each pillar can be secured to another component using a thread stepped dowel comprising of a base section, at least one middle section, and a tip section, with each section being progressively smaller in circumference than the last. The at least one middle section of the threaded stepped dowel further comprises thread spiraling around the outer surface of the at least one middle section.

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.

A shaft member having an engaging part at a lower part is formed to project from a front edge part of a plate-like fitting main body having a required thickness, and an engaging member having an engaging part at a lower part is mounted to a tip surface of the shaft member, the engaging parts communicating with each other, wherein the fitting main body has a gripping part formed of a through-hole at a central part and pin insertion parts which are formed collinearly in the vicinity of an upper edge part and a lower edge part at a rear side of the fitting main body, and wherein a shaft-member insertion part resisting shear stress is provided at a portion different from the pin insertion parts formed on the upper edge part and the lower edge part.

The present invention addresses the problem of providing a joint structure which comprises a joint member suitable for a butterfly joint, and a building. The joint structure according to the present invention includes a first wood panel, a second wood panel, and a butterfly wedge-shaped joint member for joining the first wood panel and the second wood panel. The joint structure has an allowable yield strength of about 10 kN or more. In one embodiment, the ratio of the bending strength of the wood panels to the bending strength of the joint member in the joint structure is 1:2.2 to 1:3.6. In addition, the joint structure according to the present invention may further include a joint member comprising laminated wood in which a plurality of plate materials are laminated.

A connector referred to herein as a knife plate, and the structural connections formed using the knife plate. The knife plate may have a first portion configured to affix to a first structural member, such as a vertical column. The knife plate may have a second portion configured to fit within a slot formed in a second structural member, such as a horizontal beam. The second structural member may be pinned to the knife plate using one or more dowels fit through the second structural member and the knife plate.

Each anchor includes a hollow tubular body including a first open end, a second open end, an interior including female threads, and an exterior including male threads. Each bolt includes a head and a shank. The shank includes male threads. The shank extends through an open end of an anchor. The male threads of the bolt engage with the female threads of the anchor. The seismic fuse is configured to receive the heads of the bolts and includes a hole. The rod includes an end with male threads. The rod extends through the hole of the seismic fuse into the open end of an anchor. The male threads of the rod engage with the female threads an anchor.

A locking dowel assembly for joining wooden objects without glue or screws includes a pair of cups. Each of the cups is inserted into a well in a respective pair of objects intended for joining together. A pair of inserts is provided and each of the inserts is positioned against each other such that the pair of inserts forms a cylinder. The cylinder is inserted into each of the cups for joining the objects together. A retainer is positioned between each of the inserts and the retainer has a plurality of teeth thereon. The teeth engage the cups when the insert is inserted into each of the cups thereby retaining the inserts in the cups.
