Abstract

The present invention relates to an assembly-type H-beam with a truss connection structure, comprising: an upper H-beam formed by abutting square C-shaped beams (100, 200) against each other; a lower H-beam spaced apart from the upper H-beam by a predetermined distance in parallel to the upper H-beam, formed by abutting square C-shaped beams (300, 400) against each other; and a plurality of connection means (500) which maintain the distance between the upper H-beam and the lower H-beam, and which are interconnected to form a truss structure with a triangular shape in the longwise direction. Both ends of each of the connection means have respective extensions (510, 520) formed into thin plates. The extensions (510, 520) are inserted into the gap between the abutted surfaces of the upper H-beam and into the gap between the abutted surfaces of the lower H-beam, respectively, and fastened to the square C-shaped beams by fastening means (610). The abutted surfaces of the square C-shaped beams of the upper H-beam and the lower H-beam have respective intermediate portions (120, 220) which protrude and contact each other. The extensions of the connection means are inserted onto both sides of the protruding intermediate portions, respectively, and fastened by the fastening means. The assembly-type H-beam with a truss connection structure according to the present invention applies a lightweight and strong structure, which are advantages of conventional trusses, to an assembly-type structure, to thereby overcome limits on the size of the assembly-type structure.

Description

Prefabricated H Beam with Truss Connection

The present invention relates to a prefabricated H-beam of a truss connection structure, and more particularly, by using a prefabricated truss structure to the main beam in installing the tent structure, the truss connection to be able to install a high-strength structure without the need for heavy equipment A prefabricated H beam of structure.

When installing a prefabricated structure, for example a tent structure, the size of the structure is limited depending on the size (or strength) of the main beam. In order to size the structure, a strong main beam should be used. In this case, the load of the main beam increases depending on the strength, and therefore, the heavy equipment must be used to install the structure. There is a problem that the installation cost for installing. If a high-strength H-beam is used to reinforce the strength, the strength is to be reinforced, but in the case of H-beam, heavy equipment is used as described above. The above problems have a problem that is not suitable for large prefabricated structure installation in various environments.

Therefore, there is a demand for a new type of structure capable of producing large structures using human power without mobilizing heavy equipment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a prefabricated H beam of a truss connecting structure that can produce a large structure with only human force without mobilizing heavy equipment.

It is still another object of the present invention to provide a prefabricated H beam of a truss connection structure that can be easily assembled by producing a prefabricated H-beam type beam by assembling it in a truss form.

According to a preferred embodiment of the present invention for achieving the above object,

It comprises a plurality of connecting means connected to the truss structure while forming the triangular shape in the longitudinal direction while maintaining the separation distance between the upper H beam and the lower H beam,

The connecting means is formed in both ends of the extension portion is formed of a thin plate, the extension portion is inserted into the gap between the face of the upper and lower HB beams facing each other is fixed by the 'c'-shaped beam and the fixing means ,

The middle H of the 'H'-shaped beams of the upper H beam and the lower H beam, which are in contact with each other, is formed in a protruding shape to be in contact with each other, and the extension means of the connecting means are respectively inserted into both sides of the protruding middle part. It is characterized by being fixed by.

In addition, the fixing means is characterized in that by bolt or welding.

As described above, according to the prefabricated H beam of the truss connection structure according to the present invention, since the light and sturdy structure, which is an advantage of the conventional truss, can be applied to the prefabricated structure, the limit of the size of the prefabricated structure can be greatly expanded. It has an effect.

In addition, because it is prefabricated, there is an effect that can install a large structure only by the force of a person without the help of heavy equipment.

In addition, there is an effect that can be reused after disassembly of the prefabricated structure.

In addition, since the roll forming technique is used to fabricate the prefabricated H-beam, there is an effect that can be produced even without a large temperature facility.

On the other hand, the roll forming method used in the fabrication of the prefabricated H-beam is a very efficient method as a method of plastic working of the metal, the prefabricated H-beam of the present invention, of course, other production methods such as welding, bending, forging is possible.
