Support beam structure capable of extending span and reducing height of ceiling structure and installing method thereof

Abstract

Disclosed are a support beam structure capable of extending a span and reducing a height of a ceiling structure and an installing method thereof. The support beam structure includes an H-beam extending in a longitudinal direction, an inclined extension part fastened to a lower surface or a side surface of the H-beam and inclined in such a way as to flare at an upper end thereof, a reinforcing part for reinforcing the inclined extension part, a deck placed on an upper end of the inclined extension part, and a concrete layer for filling a top of the inclined extension part, a top of the H-beam, and a top of the deck.

         14 . A support beam structure capable of extending a span and reducing a height of a ceiling structure, the support beam structure comprising:
 an H-beam extending in a longitudinal direction;   an inclined extension part fastened to a lower surface or a side surface of the H-beam, and inclined in such a way as to flare at an upper end thereof, and inclined at an inclination angle of about 35 to 75 degree of the inclined surface;   a reinforcing part for reinforcing the inclined extension part, and formed of a flat plate metal or a reinforcing bar material, and horizontally bent at opposite ends thereof to form horizontal fastening portions that are fastened to the H-beam and the inclined extension parts;   a deck placed on an upper end of the inclined extension part; and   a concrete layer for filling a top of the inclined extension part, a top of the H-beam, and a top of the deck.   
     
     
         15 . The support beam structure as set forth in  claim 14 ,
 wherein a duct or an electric wiring pipe is provided in a space outside neighboring inclined surfaces of the inclined extension part that are adjacent to but spaced between one inclined surface of the inclined extension part and another one inclined surface of the neighboring inclined extension part, and   wherein a ceiling finishing panel is placed right under a lower horizontal flange of the H-beam or placed at a position spaced apart from the lower horizontal flange.   
     
     
         16 . The support beam structure as set forth in  claim 14 , wherein the reinforcing part for reinforcing the inclined extension part is welded to the upper end of the inclined extension part and an end of the upper horizontal flange of the H-beam. 
     
     
         17 . The support beam structure as set forth in  claim 14 , wherein the support beam structure comprises:
 an H-beam extending in a longitudinal direction and having assembly parts formed on ends of upper and lower horizontal flanges, a lower assembly part of the H-beam and an upper assembly part of the H-beam being spaced apart from each other;   an inclined extension part including a lower assembly part of the inclined extension part coupled at a lower end thereof to the lower assembly part of the H-beam formed on the lower horizontal flange of the H-beam, and an upper assembly part of the inclined extension part provided on an upper end thereof that is inclined to flare out; and   a reinforcing part including a lower assembly part of the reinforcing part fastened to the upper assembly part of the inclined extension part and an upper assembly part of the reinforcing part fastened to the upper assembly part of the H-beam formed on the upper horizontal flange of the H-beam, thus coupling the inclined extension part with the H-beam and thereby reinforcing the inclined extension part.   
     
     
         18 . The support beam structure as set forth in  claim 17 , wherein the lower assembly part of the H-beam, the upper assembly part of the H-beam, the lower assembly part of the inclined extension part, the upper assembly part of the inclined extension part, the lower assembly part of the reinforcing part, or the upper assembly part of the reinforcing part is selected from a group consisting of a protruding pin, a fastening hole, a fastening ring, a surrounding part, a bent pin and an assembly pipe. 
     
     
         19 . The support beam structure as set forth in  claim 18 , wherein when the protruding pin is selected as the lower assembly part of the H-beam and the upper assembly part of the H-beam, the protruding pin includes a through hole into which a wire is fixedly inserted. 
     
     
         20 . The support beam structure as set forth in  claim 14 , wherein a non-welded portion is formed at a position on contact portions between the lower horizontal flange of the H-beam and a lower fastening bracket of the inclined extension part.
