DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truss frame joining apparatus in the construction field.

[0002]

2. Description of the Related Art Conventionally, a truss frame joining apparatus in this field has a cylindrical or spherical body as a means for joining an intersection or a gathered end of horizontal and diagonal materials called upper and lower chords or lattices, for example. The ends of the respective components are integrally joined to the peripheral surface of the joined body by screwing, welding, or the like, with a joined body having the shape shown in FIG.

[0003]

The truss frame using the conventional truss component joining means is a fixed frame in which all joints are fixed, and once joined, the frame can be disassembled again. Due to the difficulty, temporary constructions cannot be disassembled after use and are therefore unsuitable for relocation of constructions. Therefore, an object of the present invention is to provide an assembling / disassembling truss frame capable of setting up a temporary building which is easy to assemble and disassemble so as to be suitable for temporary construction at a product exhibition hall or various entertainment halls and the like. And

[0004]

According to a first aspect of the present invention, there is provided a truss frame having a cylindrical member formed by integrally joining ends of a plurality of horizontal members and diagonal members which are gathered from the periphery toward a central joint. A plurality of horizontal members and a plurality of slant members which are gathered from the periphery on the peripheral surface of the cylindrical member. A plurality of hooks engaged with the juxtaposed locking holes are fixed by a fixing tool inserted into the hollow of the cylindrical body, and are integrated together. In the fixing tool, the insertion plug projecting from the center is inserted into the cavity from the upper end or the lower end of the tubular body,
A threaded rod is inserted through a through hole formed in the center of the insertion plug, and the inner end of the set of hooks is clamped and engaged between fixtures which are vertically inserted and opposed to each other. , The plurality of hook inner ends gathered in the connector are integrally fixed.

[0005]

After each end of the horizontal member and the diagonal member is gathered from the periphery into a joint made of a cylindrical body, the hook at each end is engaged with each locking hole in the peripheral surface of the joint. Since the inner ends of the hooks are fixed by fasteners in the joint cavity, truss components such as horizontal members and diagonal members are integrated at each end and strongly joined, and at the joint, No sway such as horizontal and vertical vibration of each material occurs, and a sturdy truss frame is constructed. The truss frame is easily disassembled by unscrewing the fixture and pulling it out, disengaging the hooks at each end of the horizontal and diagonal members from each locking hole and separating them from the connector. I do.

[Effects of the Invention] Since the joining device is configured so that a plurality of ends of truss frame members such as horizontal members and diagonal members are gathered and joined via a joint so as to be capable of being separated and joined, a temporary truss frame that can be assembled and disassembled is provided. The present invention can be applied to buildings and structures, and can be constructed into an easily relocated assembly structure. By fixing the inner ends of the hooks respectively engaged with the plurality of locking holes juxtaposed on the peripheral surface of the joint with a fixing member in the joint cavity, the engaging portions are integrally formed. Because it is joined to the truss frame, the truss frame is not easily disintegrated.
It is easy to disassemble it by removing the fixture.
Since a plurality of truss components (horizontal members and diagonal members) are joined in a three-dimensional radial manner with the joint being the pivot (axis) at the center, the load applied to the frame is dispersed in each direction, and Since the force is shared by each component and responds to the load, the frame has a strong stress against impact. An L-shaped recess is provided at the head of each engaging piece of the horizontal material and the oblique material, and a protruding piece is provided at the lower end, and the inner end of the insertion plug of the fixture is fitted into the recess,
The projection is brought into contact with the outer peripheral surface of the connector and the hook is engaged with the locking hole of the connector and fixed. It is powerful.
