Abstract: Provided are frame members from which a structure can be efficiently assembled, and a structure using the frame members. On a surface of a vertical frame member 28, there are printed a position identification mark (sectional shape mark) showing the position where a horizontal frame member 34 is to be butted, a nut position identification mark N showing the mounting position of a nut 46 which is to be inserted into a guide groove 22, and a position identification mark showing the mounting position of a bracket 42. The frame members can be efficiently assembled to manufacture a structure, without referring to a drawing for assembly.

Abstract: A computer acquires maximum lengths of a structure as measured along X-axis, Y-axis, and Z-axis directions, and acquires numbers of divisions of line segments which extend along the X-axis, Y-axis, and Z-axis directions, respectively, and have the maximum lengths, respectively. The computer then calculates a basic shape, which is the shape of a rectangular parallelepiped divided into a three-dimensional grid, on the basis of the maximum lengths and the numbers of divisions. The computer creates a basic frame of the structure from the basic shape by deleting a selected line, and adding a line between two selected grid points. The computer calculates structure data, which are three-dimensional data representing the structure, by arranging frame members, which are represented by three-dimensional frame member data, along lines between the grid points of the basic frame. The computer then outputs a drawing of the structure from the structure data.

Abstract: A connector or connecting together elongated frame bars having T-shaped grooves on side surfaces is a single elongated structure having a longitudinally uniform cross-sectional shape. The connector has a central wall and is symmetric with respect to the plane of this central wall. Pairs of wings protrude from the central wall to be inserted into the grooves in the frame bars to be connected. The wings of one of the pairs protrude perpendicularly to the central wall. The wings of the other pair are cross-sectionally Z-shaped so as to be able to elastically engage in and with the grooves of the frame bars. Each wing has a mutually outwardly protruding part with a slope for being pressed against edges of the grooves such that the connector can be correctly positioned.

Abstract: A connector structure for connecting together a plurality of elongated frame bars at their ends includes a main part having three side walls with mutually perpendicular quadrangular outer surfaces and a cover piece also having three side walls with mutually perpendicular outer surfaces such that they together assume a cubic form when they are attached to each other in a closed relationship with an engagement member on the inner surfaces of the three walls of the main part and a protrusion on the cover piece engaged to each other. Each side wall of the main part is provided with a throughhole for passing a screw through such that it can be attached to end surface of a frame bar. Such main part is produced by using only two mold pieces, an upper molding piece with a convex part and a lower molding piece with an indentation. The indentation has three inner surfaces, each making a same angle to the vertical direction.
