The present invention relates to an apparatus for adjusting the truss installation angle of a prefabricated structure, and more particularly, a prefabricated structure for freely setting an installation angle of a truss member constituting the structure as an auxiliary means connecting the truss members or the truss member and the connection unit. Of the truss installation angle control device.

In general, a prefabricated structure is a facility that is installed indoors or outdoors by using a plurality of connecting members composed of pipes, truss members, or panels, and is installed in various forms such as a performance hall, an exhibition hall, an advertisement tower, or a sculpture. It is widely used at the event site because of its excellent assembly ability while maintaining stability.

Such a prefabricated structure completes a structure by arranging the standardized truss members, which are manufactured to have a constant length, cross each other or are arranged side by side, and an auxiliary construction means for connecting these truss members between the truss members. Cube or circular connection units are widely used.

The connection unit is a different connection member that is different in its structural shape depending on the overall structure or installation angle of the assembly structure is selectively used, these are also called tera ball, spherical joint unit, connecting member and the like.

As a representative of the connection unit for implementing such a function, together with the Republic of Korea Patent Registration No. 376542, 376543, Publication No. 2002-71873, 2001-67543, and Registration Utility Model No. 234930, 302425, 302427 Various structures, including 302428 and 231217, are also being introduced.

They consist of six-sided cubes and have six mating surfaces. Each mating surface has only four truss fixing pin insertion tubes, so that the six directions of the connecting unit (X, -X, Y, -Y, Z,-) In the installation angle range of 90 ° or 180 ° limited to the Z direction), there is a structural limitation that the truss member is limited to be installed.

In order to improve this disadvantage, a connection unit with an increased number of coupling surfaces has been introduced in Korean Utility Model Registration Nos. 302425 and 231217. These connection units have a spherical shape by extending the number of coupling surfaces to 18. In addition to the basic six directions (X, -X, Y, -Y, Z, -Z directions), the coupling surface to which the truss member can be joined is added. Twelve inclined contact surfaces are formed with each corner portion, and the truss member coupled thereto is configured to maintain various directions and shapes.

However, the spherical connection unit, which retains 18 extended mating surfaces, requires a separate branch connector to connect the truss member at an allowed angle by failing to secure a constant truss contact surface. It was acting as a cause to reduce workability by greatly increasing the number of parts.

In addition to this, the present applicant has proposed a connection member having 26 installation surfaces as a whole by extending the connection surface to the position of each vertex as Patent Publication No. 2005-16727 and Utility Model No. 367699. However, this also did not overcome the limitation of not providing the modified installation angle required in the field other than the specific installation angle.

The present invention has been proposed to solve the conventional problems as described above, and its main object is to provide various installation angles while simplifying the assembling structure of each connection member.

Another object of the present invention is to provide an installation angle adjusting device of a truss to freely adjust the inclination angle of the truss member according to the site situation in the pre-assembled state through the connection of the members.

Still another object of the present invention is to allow a truss member connected at various angles to maintain a structurally strong and stable state.

The installation angle adjusting device of the truss for achieving the above object, the pair of left and right pairs of connecting plates having a plurality of bolt fastening holes on the circumferential surface thereof so as to be coupled to the truss member, the pair of opposite ends of the connecting plate and the left and right pairs A hinge shaft for rotating the connecting plate of the rotating plate, and an adjusting screw rod formed on both the left and right sides of the pair of right and left sides thereof so as to be screwed across the pair of right and left connecting plates. It is characterized in that the inclination angle of the pair of left and right connecting plates on the basis of the hinge axis is configured to be adjusted freely

At this time, it is preferable to form a handle portion in the center of the adjustment screw rod forming a screw portion that is symmetrical.

More preferably, in the left and right pair of connecting plates, a cutting groove is provided so that the adjusting screw rods can be installed across, a pair of fixing frames are formed on the upper and lower sides of the cutting groove, and the fixing frame has left and right sides of the adjusting screw rods. It characterized in that the rotary guide member is formed to enable the rotation operation to form a screw coupling hole in the inner surface to be coupled to the screw portion.

And, both ends of the adjustment screw rod is characterized in that the locking nut for preventing loosening is configured.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
