diameter pipes diameter pipes - The joining end face of each pipe is processed via a laser beam machine to have an end face shape capable of realizing a surface contact with the joining plane of the joint. Then, simultaneously when performing the end face processing, a tenon, a mortise and a tenon groove for joining pipes are processed.

Ajig unit 150 placed in an exchangeable manner on the table 120 is composed ofmultiple plate members - These plate members are subjected to high-precision processing via the laser beam machine, and a profile P1 defined on the upper surface constitutes a shape for supporting the
pipe structure unit 10 from underneath. The processing data of this profile are computed based on the three-dimensional CAD and CAM data of the joint portion. - FIG. 5 illustrates the step of assembling the
pipe structure unit 10 on theassembly jig 100. - The eight pipes constituting each
pipe structure unit 10 have their respective upper end faces fixed to pillars, girders and beams. - FIG. 5 illustrates a state in which the upper ends of the third large-
diameter pipe 40 and the fourth large-diameter pipe 50 are fixed to the twopillars - For this fixture, a plate-
like mounting unit 45 is disposed on the upper end of thepipe 40, and asimilar mounting unit 55 is disposed on thepipe 50. -
Mounting plate members pillars plate member 205 hasbolt holes 206 for mounting, and similar bolt holes are provided on theplate member 215. - Now, the steps for assembling the fourth large-

assembly jig 100 is adjusted to facilitate assembly of the joint portion. - Naturally, gaps required for joining or gaps corresponding to tolerances exist between the tenons, mortises and tenon grooves constituting the joint portion of the assembled
pipe structure unit 10. - Furthermore, since the upper portions of the
pipe structure unit 10 are temporarily tightened to the corresponding members, gaps also exist at the temporarily tightened portions. - Thus, in the above-mentioned state, the
jack 130 is operated to lift the table 120 in the direction of arrow Z. By this operation, the gaps formed at the joints of thepipe structure unit 10 and the gaps formed at the temporarily tightened portions on the upper ends of the pipes are compressed. - In this state, the bolts and nuts of the temporarily tightened portions of the pipes are fully tightened. Next, the joint portions of the
pipe structure unit 10 are fixed via spot welding and the like. - After this process is completed, even if the
jack 130 is operated to lower the table 120 and thejig unit 150, thepipe structure unit 10 will be fixed securely to thepillars - By repeating the above-mentioned processes, a building structure defining a large space without pillars in the interior thereof can be built easily.

pipe structure unit 10 is viewed from below. - The ends of the pipes are fixed securely via bolts and nuts to the structure such as pillars, girders and beams. Further, the joint portion of the
pipe structure unit 10 is also securely formed via spot welding W1 and the like. - The
channel member 12 can be used for example as a member for supporting the ceiling member, or for attaching lighting equipments.
