C-type frame {C-type flame}

[0001] The present invention relates to a C-shaped frame adapted to be used as a support for a facility such as a prefabricated building or the like, and more particularly to a C-shaped frame which is reinforced by torsion strength so as not to cause warping and torsional deformation by a load, The present invention relates to a C-shaped frame, which has a resilient force with respect to a fastening element and has a restoring force when the fastening element is fastened to another structure through a nail.

Generally, a frame for supporting and fixing a wall of an outer wall of a building is formed of a rod-shaped rolling material having various sectional shapes.

Such a frame is formed by injecting into a mold of a footstep, forming a steel ingot, removing impurities and making it dense, reheating it in a heating furnace, hanging it on a rolling mill, finishing it with various cross-sectional shapes through several stepping rollers Type frame, an I-type frame, a C-shaped frame, a Z-shaped frame, a T-shaped frame, and a C-shaped frame depending on the sectional shape.

In the above, the C-shaped frame is combined with a panel coupled with the C-shaped frame to be used for interior decoration and construction, and is mainly used for a frame or the like in a partition of a wall.

Such a conventional C-shaped frame has a simple cross-sectional structure and is poor in durability, which is weak to the weight and external impact of the panel after being installed on the outer wall of the building.

Accordingly, recently, a C-shaped frame having improved structural durability has been proposed. One of them is Korean Utility Model Registration No. 20-0431791 (name: a C-shaped steel having improved durability) , The panel is inserted and fixed in the open portion thereof as described in the publication, the C-shaped steel is provided on the bottom surface and both side surfaces thereof for reinforcement in the longitudinal direction so as to prevent the panel from being deformed by the weight of the panel, And a groove is formed.

That is, the strength is reinforced by the grooves.

The C-shaped frame described in the present invention can be called a C-shaped steel, and is generally referred to as a C-shaped frame.

However, in the conventional C-shaped frames, as shown in FIG. 6, the flexural and torsional strengths are not reinforced, and there is a problem that the flexural and torsional deformations are caused by the load.

Further, when the other structure is fastened and fastened through a fastening element such as a screw, there is a problem in that it can not be restored and is easily separated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a torsional strength strengthening device, The present invention provides a C-shaped frame having elasticity with respect to a fastening element and having a restoring force so as to be more firmly engaged with the fastening element.

In order to accomplish the object of the present invention, the C-shaped frame according to the present invention is used as a support for fixing a wall when constructing a facility, and includes a vertical surface, an upper and lower surfaces extending in one direction from the upper and lower ends, Shaped C-shaped frame having a " C " Wherein the vertical surface is provided with reinforcing recesses formed in the opening side direction between both ends of the upper and lower surfaces; The reinforcing concave portions are formed on the vertical plane so that a plurality of reinforcing concave portions are arranged with an interval therebetween in the longitudinal direction.

The reinforcing concave portion is provided with an elastic protruding portion protruding in a direction perpendicular to the vertical surface so that the reinforcing concave portion can be elastically supported and fixed when the fastening element penetrates and engages.

In the C-shaped frame of the present invention as described above, not only the strength is reinforced through the reinforcing recess, but also the flexural and torsional strength is reinforced with respect to the vertical load applied to the vertical surface, and the flexural and torsional deformation In particular, when the wall is forcedly coupled to the wall by means of a fastening element such as a screw or the like by the elastic protrusion, the fastening element can be easily pulled out by the restoring force due to its own elasticity So that it is possible to maintain a firmly fixed state by increasing the coupling force.
