PURPOSE: A prefabricated supporting beam structure and an installation method thereof are provided to enhance the utilization efficiency by extending a span that a distance between columns of a building and to reduce a ceiling height. CONSTITUTION: A prefabricated supporting beam structure(A) comprises an I-beam(1), an inclined extension(2), and a connection bar(3). The I-beam is extended to a longitudinal direction. One end part of the inclined extension is fixed to a lower horizontal support plane of the I-beam by being assembled and extended to be inclined and widened to upward. Both end parts of the connection bar are assembled and fixed to the upper horizontal support plane(12) of the I-beam and the upper part of the inclined extension to reinforce the inclined extension. |
