A Steel Beam Adapted Prestress in Web Width of Steel Beam Using H-beam or I-beam

摘要

The present invention applies the prestress to the steel beams within the web width of the steel beams using the H beam or the I beam, which is applied to the building, etc. It is about.;Prestressed steel beams are applied horizontally to the upper and lower sides of the web and the web in the vertical direction within the width of the web of the steel beam using the H beam or the I beam according to the present invention. Steel beam having a, and mounting members mounted inside the steel beam, and a tension member for applying prestress to the steel beam within the width of the steel beam with a predetermined tensile force with a fixed point on each of the mounting members.;According to the present invention, it is possible to prevent the cracks that may occur in the concrete of the upper slab (Slab) when the steel beam overcomes sagging and the design load action without increasing the mold height, it is possible to implement the long span of the beam. Furthermore, since the steel beams that apply prestress within the width of the steel beams according to the embodiment of the present invention implement the steel beams of the long span without increasing the height of the steel beam, it is of course possible to design a building with a large number of floors at a predetermined height. By minimizing the number of spaces, a variable space is secured enough to enhance the aesthetics of buildings such as performance halls, department stores, and parking lots, and secure design variability.
