FIG. 4 is a view showing a round type pipe, and FIG. 4D is a view showing an end face thereof. Each pipe part 53P constituting the pipe assembly 60 has two types of pipe members 53R shown in FIG.
It was produced by processing. Although the end face shapes are only the square shape and the round shape, those having various sizes are used for the pipe length, the end face size, and the like.

As described above, as shown in FIG. 19, a long member having various cross-sectional shapes such as a circle, a square, an H shape, an L shape, and a C shape is mounted on the work support 10a of the laser processing apparatus 1. Since the member mounting portions 10c corresponding to the respective members are formed so as to be able to be formed, both of the two types of pipe members 53R can be mounted on the work support 10a. Further, the chuck devices 13, 39, 4
In 3 and 47, when gripping the pipe member 53R, the gripping portions 27b and 30b (the roller gripping portions 27c and 30b) are used.
c) at the same time, in the direction of the central axis CT1, each gripper and the central axis C
Since it moves at the same speed in such a manner that the distance L1 to T1 is always equal, it is centered so that the center position of the square circumscribing the cross-sectional shape of the pipe member 53R coincides with the center axis CT1. In addition, a pair of each gripping portion facing each other is
When the reaction force due to the gripping acting on the pair reaches a predetermined value, the driving of the corresponding drive cylinder 25 is stopped, so that the pipe member 53R is directed inwardly of each pair such as a rectangular cross section. Even if the amount of movement in the direction of arrow Q is different, the pipe member 53R can be gripped with an appropriate gripping force. That is, the above-described pipe members 53R having various types and sizes are appropriately processed by the laser processing apparatus 1.

FIG. 24 and FIG. 25 are views showing an example of processing a pipe part. In FIG. 24, a square type pipe part 5 is shown.
Examples of seven processing patterns related to 3P are (a) and (b), (c) and (d), (e) and (f), (g) and (h), (i) and (j), ( k) and (l), and (m) and (n) are shown by a set of plan and side views.
Of these, the processing patterns indicated by (a) and (b), (c) and (d), (e) and (f), (g) and (h), and (i) and (j) Since the engaging part 53a for engaging and connecting with another pipe part 53P is formed at or near the end of the pipe part 53P, the chuck device 13,
What is necessary is just to grind and process the pipe member 53R in a cantilever shape by 39.

(K) and (l), (m) and (n),
In the case of the processing pattern indicated by, the engaging portion 53a is processed at the center or the like of the pipe part 53P, so that the chuck members 13, 39, 43, and 47 use the pipe member 53R.
May be processed by gripping on both sides. As already mentioned,
Since the torch 37 is movable and positionable in the Y-axis, Z-axis, A-axis, and B-axis directions, three-dimensional three-dimensional machining of the pipe member 53R as shown in FIG. 24 is easily realized. Needless to say, processing patterns other than the example shown in FIG. 24 are also possible. Further, a round type pipe member 53
R is processed to form a pipe part 53P as shown in FIG. 25 ((a) is a plan view, (b) is a side view, and (c) is a view showing an end face).
Can be processed in the same manner as in FIG.

The pipe parts 53P subjected to various processes as described above are engaged and connected via the engaging portions 53a to assemble and construct the pipe assembly 60. FIG. 26 is a diagram showing connection points between pipe parts. FIG.
(A) is a sectional view taken along line B1-B2 in FIG. 21, and (b) is a sectional view taken along line C1-C2 in (a). The plate portion 65b of the beam-side pipe part 53P is inserted into the slit-like groove 65a (engagement part 53a) formed in the roof-side pipe part 53P.
By inserting the (engaging portion 53a), the two pipe parts 53P, 53P are engaged and connected. FIG. 26
(C) is an enlarged view of a portion denoted by reference numeral D1 in FIG. 21.
The pipe part 53P, which is a column in the vertical direction, and the pipe parts 53P, 53P, which are beams in two horizontal directions, are pipe parts 5
It is combined so as to be joined at one place using an engaging portion 53a formed of a slit or the like formed in 3P.

In addition, a pipe assembly 60 is constructed by appropriately engaging and joining pipe parts 53P processed as shown in FIGS. 24 and 25. Since the processing of the pipe part 53P is performed with high accuracy by the laser processing apparatus 1 of the present embodiment, the pipe parts 53P, 53P to be engaged and joined together are tightly combined without play. Thereby, the pipe parts 53P, 53P
A high quality pipe assembly 60 is realized without performing welding or bolting between the pipes. For this reason, the disassembly and the assembly of the pipe assembly 60 can be easily performed. Of course, welding, bolting, and the like can be performed. It is also possible to provide a flange or the like for bolting on the pipe.

As described above, since the pipe member 53R was processed using the laser processing apparatus 1 which is a three-dimensional linear processing apparatus, the pipe assembly 60 could be mass-produced with high quality. In addition, since the assembly is constructed using metal pipe members, it is not necessary to use wood, and the protection of forest resources is promoted. In the above-described example, the pipe assembly 60 is a skeleton of a pipe house. However, the pipe assembly may be a skeleton for other buildings or a non-building skeleton.

It is noted that the pipes may be welded to each other when constructing the pipe assembly. However, the above-described laser processing apparatus may be provided with a function of welding long members (pipe parts). It is possible. The welding can also be performed by the laser from the torch 37. In this case, the welding may be performed with an output lower than the laser output at the time of cutting. Usually, such welding is often performed along the cut edge of the long member. Therefore, it is preferable to use the processing path used for cutting the long member as the processing path for welding.
