A truss structure to support interior and exterior decorative material of a building is provided to reduce the danger of the fire and reduce the amount of electricity by assembling a vertical member and a horizontal member without a welding process. A truss structure to support interior and exterior decorative material of a building comprises a plurality of vertical members(10), a plurality of horizontal members(20), and a plurality of support brackets. A plurality of vertical members are fixed to a stair slab or an inter-stair retaining wall with a first connecting bracket. A plurality of horizontal members are connected to the vertical member with a second connecting bracket. A burring part is formed at the vertical members and the horizontal members. On the inner circumference of the burring part, a screw tap is formed owing to the rolling tapping. The burring part is formed so that a peripheral part is inclined. The peripheral part of the burring part is elastically coupled by being pulled according to fixing a bolt to the burring part. |
