Then, both end portions 449 of the U bolt 427 are provided with a male screw portion 451 for fastening, and are inserted into the through holes 441 and 441 or the through holes 443 and 443 of the flange portion 437 and screwed with nuts as female side fastening members. .

  As a fifth example, as shown in FIGS. 16, 17, and 18 (a) and (b), the first coupler 510 and 610, the second coupler 520 and 620, and the adjusting screw 530, respectively, 510 and 610 and the second couplers 520 and 620 are composed of two to four insertion rods 512 and 612 arranged in three orthogonal directions and configured to be inserted into one end of a pipe (not shown). 522, 622 and central bodies 514, 614 and 524, 624 connecting one end of each of the insertion rods 512, 612 and 522, 622 as a single piece, and the insertion rods 512, 612 of the first couplers 510, 610, respectively. Each of the insertion rods 522 and 622 of the second couplers 520 and 620 has a substantially cylindrical shape of a cavity, and one surface thereof is in close contact with each other. At this time, the plurality of mounting protrusions 515, 615, and 525 are formed on any one or both of the contact surfaces of the two insertion rods 512, 612 and 522, 622, and the two insertion rods 512, 612 are formed. 3 types (three-dimensional three-branch, four-branch and five-branch connectors) that support the inner circumference of the contact surfaces of 522 and 622 and accurately position them when connecting are proposed. (See Patent Document 4).

  The plurality of mounting protrusions 515, 615, and 525 are formed on any one or both of the contact surfaces of the two to four insertion rods 512, 612, 522, and 622, respectively, and the two to four insertion rods 512, The inner peripheries of the contact surfaces 612, 522, and 622 are supported, respectively, and are accurately positioned at the time of connection. After the first couplers 510 and 610 and the second couplers 520 and 622 are in close contact with each other on one surface, the pipes are inserted into the insertion rods 512 and 612 and 522 and 622, respectively.

  18 (a) and 18 (b), the three-dimensional five-branch connector has four horizontal insertion rods 612 arranged on one plane at an angle of 90 °, and one vertical insertion rod 630 is horizontal. It is arranged in a direction perpendicular to the insertion rod 612.

  The insertion groove 632 formed inside the vertical insertion rod 630 has an inclined portion 634 formed so that the diameter thereof is reduced at the end portion thereof and communicated with the slit 636, and an adjustment screw rod 530 has an inclined portion 531 formed at an end portion thereof so that it can be inserted into the inclined portion 634 of the insertion groove 632. Thus, when the adjustment screw rod 530 is advanced using a wrench with the horizontal insertion rods 612 and 622 and the vertical insertion rod 630 inserted into the pipe, the end of the adjustment screw rod 630 is inserted into the insertion groove 632. To push the end, the first coupler 610 and the second coupler 620 are spaced apart from each other. Thus, since a gap is formed between the two horizontal insertion rods 612 and 622, the inner peripheral surface of the pipe is firmly supported, and at the same time, the inclination formed at the end portion of the adjustment screw rod 530 Since the portion 531 is forcibly inserted inside the insertion groove 632 and pushes the inclined portion 634 formed at the end portion of the insertion groove 632, the slit 636 is expanded to increase the outer diameter of the vertical insertion rod 630. To do.

  However, in the three-pronged joint 103 described in Patent Document 1, the corner crossing portion where the three square pipes cross in a three-dimensional direction orthogonal to each other can be made relatively smart, and a frame structure with a single quadrangular cross section is possible. However, since the three crossed pipes cannot be connected to the intermediate crossing part that crosses each other in the three-dimensional direction, it is not possible to form a complex arbitrary-shaped three-dimensional frame structure with a plurality of quadrilateral cross sections, and the degree of design freedom is increased. No. Further, since the three-pronged joint 103 has a complicated and heavy construction, there are problems such as an increase in manufacturing and transport costs.

  In one fastening device 210 described in Patent Document 2, a corner crossing portion and an intermediate crossing portion in which two pipes cross in a two-dimensional direction orthogonal to each other can be coupled, but three pipes crossing in a three-dimensional direction. Unable to join the pipes. For this reason, in order to connect pipes that cross in one three-dimensional direction, it is necessary to use two fastening devices 210 adjacent to each other in the orthogonal direction, which is not smart and has no design freedom. . Further, since the fastening device 210 has a complicated and heavy configuration, there are problems such as an increase in manufacturing and transportation costs.

  In one pipe clamp 303 described in Patent Document 3, a corner crossing portion and an intermediate crossing portion where two pipe materials 302 cross in a two-dimensional direction perpendicular to each other can be coupled, but three pipe crossings cross in a three-dimensional direction. Cannot join the book pipes. For this reason, it is necessary to use two pipe clamps 303 adjacent to each other in the orthogonal direction in order to connect pipes that cross in one three-dimensional direction, which is not smart and has no design freedom. However, it takes time and costs.

  In one coupler 423 described in Patent Document 4, a corner crossing portion and an intermediate crossing portion where two pipes 413 and 415 cross in a two-dimensional direction orthogonal to each other can be connected. It is not possible to connect three pipes. For this reason, in order to connect pipes that intersect in one three-dimensional direction, it is necessary to use two couplers 423 adjacent to each other in the orthogonal direction, which lacks smartness and has no design freedom. There is a problem that it takes time and costs.

  In the assembly type display stand pipe connector described in Patent Document 5, three types of three-dimensional three-branch, four-branch, and five-branch connectors are used to cross corners in which three pipes cross in a three-dimensional direction perpendicular to each other. It is possible to connect the middle and intermediate crossing parts relatively smartly and to create a complex arbitrary-shaped three-dimensional frame structure with multiple square cross-sections, but it is manufactured because three types of connectors with complicated, heavy and long structures are required. In addition, there are problems such as an increase in transportation cost.

  As described above, in the conventional three-dimensional frame structure, it is necessary to use a large number of types and quantities of connectors having a complicated and heavy structure in order to obtain a complex arbitrary-shaped three-dimensional frame structure. As a result, the manufacturing and transport costs increase, and the degree of freedom in design is lacking.
