Abstract: A structural member joint structure can easily join members to each other by using a simple structure having a reduced number of parts and can provide the members with a large fastening force which makes the members less likely to be loosened from each other. The joint structure is used to join one pillar and the other pillar to each other such that the other member is vertically abutted against a side face of the one pillar. The structure has a pair of fastening members positioned in the inside of the other pillar and arranged so as to be movable in the widthwise direction of a groove formed in a side face of the one pillar, a nut mechanism located on the inward side of the other pillar and formed between the pair of fastening members, and a bolt operated from the outside through an opening in the other pillar to be fitted into the nut mechanism. Rotating the bolt causes the nut mechanism to urge and move the pair of fastening members in the direction in which the pair is separated from each other.

Abstract: A lattice panel (1) having a simple structure and capable for easy construction of strong and comfortable building, comprising several cross-shaped first skeleton members (7) and the L-shaped second skeleton members (9), to be connected to each other, wherein a panel bodies (3) are formed by connecting the second skeleton members (9) to the outer periphery of the first skeleton members (7), and frame members (11) are attached to the outer periphery of the panel bodies (3, 5).
