Description

Stiffener {STIFFENER}

The present invention relates to a stiffener, and more particularly, to a stiffener structure for reinforcing a flange portion such as a wale and a girder in which an h beam is used, by a turnbuckle-type simple structure, To a stiffener whose structure is improved.

Generally, in order to prevent the backward flow and the air-corruption of the excavated soil in the underground openings of the existing civil engineering works, a wale band is installed as a H (H) beam so as to support the gravel, A jack is installed and used, but there is a problem that a force stress generated in the transverse wale is generated at the earth pressure and pushes the wale band, thereby separating the wale band and the brace.

In order to solve the above-mentioned problems, there has been devised a device for preventing separation between a wristband and an HR beam, and a means for fixing a wristband and an HR beam has been developed.

However, in the conventional designs, the strut wale can be used as a means by fixing the strut. However, with respect to the H Beam which must bear the load of the strut, there is a problem that the H Beam is bent or the H Be beam is bent due to the stress applied to the H Beam Could not be resolved.

This problem is caused by the stress applied to the H (H) beam, which causes bending of the surface of the H. beam. As a result, the wale is separated from the brace so that the H. beam can not support the brace, Or the collapse of the buried soil.

In order to solve the above problems, a conventional method is a H-beam image used as a wale. The stiffener cut by the steel plate is welded to the lower portion of the stiffener so that the stiffener is tightly attached to the point where the force is generated so as to increase the strength of the HIS beam to relieve the stress applied to the HIS beam. There is a problem that it causes a waste of.

The construction method of the stiffener using the HIB beam causes the construction cost to rise and becomes a factor. The welded construction is performed to bond the cut H-beam to the H-beam used as the wale, There is a risk of environmental destruction and safety accidents due to gas, and in order to dismantle the HIB used as a stiffener coupled to an HIB used as a wale during demolition after installation, it is necessary to cut the combined stiffener HIB Therefore, there is a problem that causes rise in labor costs, material loss, and waste materials.

As a conventional prior art for solving this problem, there has been known a conventional staple gun as disclosed in Korean Registered Utility Model No. 20-0270234 entitled " Styrene jack for civil engineering "(registered on March 23, 2002) A support plate formed integrally with the base plate is provided with a base plate having a bolt inner hole formed therein and coupled to the bolt inner hole of the base plate so as to communicate with each other.

As another prior art related to the conventional stiffener, as disclosed in Korean Registered Patent No. 10-1484258 entitled " HIB Beam Deformation Stiffener "(Registered on January 13, 2015), an HIB The present invention relates to an H-beam deformation preventing stiffener for preventing buckling of an H-beam, the stiffener comprising: a body having a slide hole penetrating both sides thereof; Two supports, one end of which is inserted into the slide hole of the main body opened to both sides and the other end of which is in contact with the flange; An insertion hole formed in the main body in a direction orthogonal to the slide hole and communicating with the slide hole in the main body; And a movable member having one end penetrating through the insertion hole and being in contact with one end of the support member disposed inside the slide hole, wherein one end of the movable member is formed on a first inclined surface, And a second inclined surface in contact with the inclined surface is formed. As the movable member is inserted into the insertion hole, the supporting member is linearly moved in the flange direction by the movable member, The movable member is coupled to the main body so that the two support members are linearly moved in different directions without being moved in the left and right direction.

However, existing stiffeners are in surface contact with the inner side surface of the flange in the case of a belt, and there is a fear that a slipping phenomenon may occur due to the generation of an external force at the contact portion. In addition, the support may be moved in different directions, There is a disadvantage in that the structure for contact is complicated and the maintenance of the parts is difficult and the manufacturing cost is increased.
