Since the five-axis connection joint 700 is composed of five split joints, it can be connected to the steel pipe member 100 in five branching directions, and as shown in FIG. 1, it is mainly installed in the lower part of the vinyl house frame.

Thereafter, the six-axis joint joints 200 and 300 are installed in the middle portion of the vinyl house frame as shown in FIGS. 2A and 3A. Since a plurality of six-axis joint joints 200 have six split joints 210 and 220, respectively, the steel pipe members 100 and 100a are inserted between the split joints 210 and 220, and the steel pipe members 100 are penetrated. The holes 15 and the through holes 10 of the split joints 210 and 220 correspond to each other to be fastened by a fastening member 90 such as a bolt 92 and a nut 94.

Since the steel pipe members 100 and 100a are branched and installed in six directions by the 6-axis connecting joint 200, the number of 6-axis connecting joints can be reduced, and the joints are respectively fastened at the split joints 210 and 220 and the center portions 240 and 250, respectively. Since it is fastened by the member 90, it is possible to more strongly form the frame of the vinyl house.

In addition, the side (side) of the vinyl house frame is connected as described above by using a five-axis or three-way five-axis and three-axis connection joint (800,600) as shown in FIG.

Although the structure of the vinyl house frame shown in FIG. 1 is mainly described here, the structure (the structure of the frame connection structure of the vinyl house) is changed to the second and third embodiments shown in FIGS. 4A and 5B. It can be applied using the shaft connection joint (400, 350a).

However, the present invention can be transformed into a house structure having a different shape depending on what kind of steel pipe members 100, 100a, 100b, 102 are coupled to the split joint of the multi-axial connection joint.

6A and 6B are respectively a perspective view and a longitudinal schematic cross-sectional view showing a house structure having an improved arch structure according to the fourth embodiment of the present invention.

For example, as in the fourth embodiment shown in FIGS. 6A and 6B, it may be modified into a house structure having an improved arch structure.

That is, in the house structure 4 having the improved arch structure of the fourth embodiment, the vertical surface 5 and the inclined surface 6 form a planar structure, and the connection portion 7a between the vertical surface 5 and the inclined surface 6 and the uppermost portion. The connecting portion 7b between the inclined surface 6 and the inclined surface 6 has an arch structure.

In this case, the planar structure of the vertical surface 5 and the inclined surface 6 uses a linear unit steel pipe member 100a for the steel pipe member coupled to all directions in the multi-axial connection joints 200, 400 and 350a, and the connection portions 7a and 7b. The arch structure of) is assembled using the unit steel pipe member 100 having a curved shape to the steel pipe member coupled in the longitudinal or inclined direction, except for the longitudinal direction to the multi-axial connection joint (200,400,350a) as in the above embodiment .

Since the house structure having the improved arch structure according to the fourth embodiment is formed by interconnecting a plurality of arch trusses, diamonds or rectangles similar to the first to third embodiments described above, In comparison, it forms a structure having high rigidity in the vertical and horizontal directions, and forms a structure having strong wind resistance against lateral pressure such as a typhoon.

In the above description of the embodiments, the number of the steel pipe members (100, 100a, 100b, 102) that can be connected to the split joint of the multi-axial connection joint has been described for applying three to three, but the number is limited thereto. It can also be increased or decreased depending on the user's needs.

The house structure using the multi-axial connection joint of the present invention can be widely applied to various fields to which plastic houses, greenhouses, barns, factories, hangars, warehouses and other temporary structures are applied.
