[0002]

2. Description of the Related Art When a reinforced concrete structure is made in the field of civil engineering or construction, a single / double assembled reinforcing bar and other assembled reinforcing bars are used. These have a self-evident cross structure because many rebars cross. Fences, fences, lattice doors, protective nets, etc., where long members cross vertically and horizontally or diagonally, also have an intersecting structure, and various gabions for revetment, water flow control, gardens, etc. also have this type of structure. On the other hand, containers such as baskets also have an intersecting structure, and hanger boards in which vertical and horizontal bars are combined also have an intersecting structure. There are many other structures having an intersection structure.

[0003] Among the above-mentioned crossing structures, a flat one is composed of a number of bar-like members arranged vertically and horizontally crosswise or diagonally crosswise, and the crossing portion of each bar-like member is fixed and assembled. Can be A three-dimensional cross structure such as a cylinder or a container is assembled using not only a rod-shaped member but also a frame-shaped member. Also in this case, the intersection of the members is fixed. As the fixing means, welding, adhesion, fixing of metal fittings, binding, or the like is appropriately adopted according to the material.

[0004] The cross structure is made by hand or by mechanized means. By the way, when a flat cross structure is made by hand, these cross portions are fixed while each bar-shaped member is cross-arranged according to the procedure. One example of mechanized means is vertical

The above-mentioned crossing structure does not have any particular difficulty in making it by either manual or mechanized means. However, the following can be said from the viewpoint of the relationship between the strength and the number of manufacturing steps. A single cross structure does not require any manufacturing steps, but is inferior in strength to a double or higher cross structure. Conversely, a double or more crossed structure is superior in strength, but requires a lot of labor. Further, as each crossing structure increases in size, the number of manufacturing steps increases. In particular, if the structure is a three-or-more-intersection structure and is large, not only is it troublesome, but also the production difficulty increases.

[Claims] The present invention is characterized in that three or more unit elements for row formation comprising a plurality of bar-shaped members arranged in parallel are provided, and that three or more unit elements are fixed and integrated in an overlapping arrangement with each other. The two unit elements adjacent to each other and overlapping with each other, each bar-shaped member of one unit element and each bar-shaped member of the other unit element intersect,
An intersecting structure characterized in that a connecting space is interposed between two unit elements sandwiching each bar-shaped member of one unit element. 2. The crossing structure according to claim 1, wherein all the unit elements are formed by arranging straight rod-like members. 3. The crossing structure according to claim 1, wherein unit elements formed of juxtaposed straight bar members and unit elements formed of juxtaposed curved bar members are alternately overlapped. 4. The crossing structure according to claim 1, wherein all the unit elements are formed by arranging curved rod-shaped members. 5. The rod-shaped member of one unit element and each rod-shaped member of the other unit element intersect at right angles with respect to two unit elements that are adjacent to each other and overlap with each other. Crossing structure.
Outside bar 6. The two unit elements which are adjacent to each other and overlap each other, wherein each rod-like member of one unit element and each rod-like member of the other unit element intersect at a non-perpendicular angle.
An intersection structure according to any of the above. 7. The intersection structure according to claim 1, wherein a plurality of rod-shaped member ends protrude from at least one of the plurality of edges. 8. The crossing structure according to claim 1, wherein ends of the plurality of rod-shaped members are bent in a direction in which the unit elements overlap. 9. When the distance between the first and second rod-shaped members from the edge is H, and the length of the end of the rod-shaped member protruding from the edge is L, these are H ≦ L. The intersection structure according to claim 7 or 8, which satisfies the relationship. 10. The crossing structure according to claim 1, wherein a rod-shaped member having an engaging portion having an arbitrary shape selected from a hole shape, a channel shape, and an angle shape at its end is mixed. 11. A plurality of crossing structures according to any one of claims 1 to 10, and these crossing structures are connected to each other directly or via a connecting member. Crossing structure linking.
