Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the prefabricated building according to the present invention.

1 shows a small diameter circular steel pipe 5, a bidirectional fastening bolt / nut 7 and a hexahedral connector 3A according to the present invention, and FIG. 2 shows a small diameter circular steel pipe 5, bidirectional according to the present invention. 3 shows a binding bolt / nut 7 and a spherical connector 3B / 6-way connector 3C, and FIG. 3 shows a large diameter round steel pipe 10, a bidirectional binding bolt / nut 7 and It is a figure which shows the hexahedral connector 3A.

1 to 3, in the prefabricated building according to the present invention, both ends of the circular steel pipes 5 and 10 are assembled to the nut portions of the bidirectional binding bolts / nuts 7, respectively, and the bidirectional binding bolts / nuts 7 ) Bolts are assembled to the nut holes 4 of the connectors 3A and 3B. In this way, the plurality of circular steel pipes 5 and 10 are assembled through the connectors 3A and 3B and connected to each other to form a basic frame of the prefabricated building. That is, the round steel pipes 5 and 10 are bidirectional fastening bolts / nuts which can be assembled by rotating the round steel pipes 5 and 10 and the connectors 3A and 3B in opposite directions, respectively, for fast and robust assembly without welding each other. Assemble the connector coupling bolt (1) of (7) through the steel pipe coupling nut (2) into the nut hole (4A) of the hexahedral connector (3A) or assemble into the nut hole (4B) of the spherical connector (3B). do. By repeating the process of joining the circular steel pipes 5 and 10 to the connectors 3A and 3B without welding each other, a circular steel pipe structure composed of the circular steel pipes 5 and 10 is produced. In addition, the circular steel pipe (5, 10) is coupled to the six-way connector (3C) may be coupled to a plurality of circular steel pipe (5, 10) in the x-axis, y-axis and z-axis direction.

At this time, the bidirectional binding bolt / nut (7) is composed of a connector coupling bolt (1) and a steel pipe coupling nut (2), before the connector of the circular coupling (5, 10), the connector coupling bolt (1) and the steel pipe coupling nut ( 2) must be assembled in advance. Small-area single-story buildings use short diameter small diameter round steel pipes 5, and large area buildings preferably use long diameter large diameter round steel pipes 10.

The coupling structure of the circular steel pipe according to another embodiment of the present invention is shown in Figures 15 to 16. Referring to Figure 15, the basic frame of the prefabricated structure according to the present invention is the same as described above using a circular steel pipe structure. However, as shown in FIG. 15, a plurality of half pipes 11 and 12 are coupled to both ends of the circular steel pipe 5 to surround the ends of the circular steel pipe 5, and the plurality of half pipes ( Outside the 11, 12, the ring fixing portion 20 for fixing the combined half pipe (11, 12) is located, by rotating the bolt (8) connected to the plurality of half pipe (11, 12) half pipe (11, 12) 6) to bind the circular steel pipe (5) by expanding the internal binding portion (6) located in the inner half of the tube to fit the inner diameter of the circular steel pipe (5). At this time, a circular rail groove (not shown) may be generated at a portion to which the plurality of half tubes 11 and 12 are joined to inject an elastic body into the circular rail groove, thereby further strengthening the binding of the circular steel pipe 5 described above.

Referring to FIG. 16, the first pipe 16 is inserted into the circular steel pipe 5, and one end of the first pipe 16 has an internal inclination formed therein so that the bolt may pass through and fixed to the protrusion of the bolt. A nut is fixed to one end of the first tube 16, and one end of the first tube 16 having an internal inclination forms a plurality of cut portions cut in the tube direction of the first tube 16. Therefore, when the nut is rotated toward the bolt, the above-described cutting part expands and binds to the circular steel pipe 5. At this time, the saw blade 22 is formed on the outer surface of the cut portion so that the saw blade 22 is embedded in the inner diameter side of the circular steel pipe 5 can further strengthen the binding of the circular steel pipe (5). In addition, referring to FIG. 17, the circular steel pipe 5 may be connected to each other in the x, y, and z axis directions by orthogonally assembling the plurality of circular steel pipes 5 through an orthogonal connection part 50.

The hexahedron connector 3A is mainly used when assembled with the small-diameter circular steel pipe 5, and has a weaker property than the spherical connector 3B because the pitch number to which the bidirectional binding bolt / nut 7 is assembled is small due to the hexahedron structure. The spherical connector 3B is mainly used when assembled with the large-diameter circular steel pipe 10, and has a stronger pitch than the hexahedron connector 3A because the pitch number of the bidirectional binding bolts / nuts 7 is assembled because of the spherical structure. However, due to the nature of the spherical structure to process the nut around the hole (4B) flat so that the two-way binding bolt / nut (7) can be firmly assembled.

As the lower sub-connector 14 has a long diameter of the small diameter circular steel pipe 5 as shown in FIG. 5, the above-described bending strength problem occurs, so that the end of the small diameter circular steel pipe 5 is distributed to distribute the floor load. Install in the part. Also, as shown in FIG. 6, the balanced sub connector 17 is engaged with the square steel pipe binding bolt 18 of the square steel pipe 13 to distribute the floor load of the large-diameter circular steel pipe 10 so as to share the floor load. do.
