Union Type Multiple Axile Coupling Joint for Structure of Steel Pipes}

The present invention relates to a multi-axial connection joint for connecting the steel pipe pipes to each other in order to build a structure with steel pipe pipes

In particular, the present invention relates to a multi-axial connection joint that connects a plurality of rectangular steel pipe members in the horizontal axis, vertical axis, and height axis directions to build a three-dimensional frame.

The present invention has a fastening method that is easy to assemble, install and dismantle in constructing a structure using a multi-axis steel pipe pipe member in the direction of the horizontal axis, vertical axis, height axis, and to build a structurally strong and robust structure.

In particular, the present invention has a structure for easily assembling and fastening a rectangular steel pipe having a rectangular cross section in addition to the steel pipe having a circular cross section.

In another aspect, the present invention to provide a pipe connection joint to build a structure of various types with a minimum connection joint standardized in building a three-dimensional structure.

In general, steel pipe scaffolding is a structure in which steel pipe pipe members are installed in a horizontal and vertical direction by using clamps, and long steel pipe pipes are installed in vertical and horizontal directions or laid down, and joints of respective steel pipe pipes are installed. There is a separate clamp to see the construction of the temporary construction.

As described above, the temporary structure to be assembled by clamping has the trouble of construction, and the vertical and horizontal steel pipe members joined by crossing the clamps at right angles do not coincide with the central axis so It can be seen that there is structural irrationality such as being transmitted.

In addition, a vinyl house, a medium-large barn, and a greenhouse structure, which mainly use steel pipe pipe members, can be seen to form a structure by tying a vertical steel pipe member, which forms a frame in the longitudinal direction, and a horizontal steel pipe member, which has a purlin direction, with a wire stopper. have.

However, the structure of the steel pipe pipe framework, which is constructed by the above coupling method, has a structure that is difficult to withstand large loads or wind pressures acting in the vertical or horizontal direction, and is easily damaged or damaged by heavy winds or heavy snow accompanied by heavy rain. It can be seen that there is a problem of enormous property loss.

Steel pipe pipe members are mainly produced with circular steel pipes with a circular cross section and square steel pipe pipes with a square cross section. Circular steel pipe pipe members are the main structural members of various temporary structures such as steel pipe scaffolding, barns, and vinyl house facilities. Although the usability is very wide, the square steel pipe member is more difficult to deform than the round steel pipe member, and the connection of the square steel pipe pipe depends on the welding method rather than the fastening method using fasteners. The use was limited except for roof trusses and warehouse structures.

As a prior art for constructing a pipe fastening structure or a frame for constructing a prefabricated structure or a simple structure, which can be seen in the patent and utility model publications, the following can be seen.
