PURPOSE: A truss device is provided to facilitate the connection to a support column using a wedge unit. CONSTITUTION: A truss device (100) comprises an upper horizontal member (110), a lower horizontal member (120), vertical connection members (132,134), slope connection members (136,138), and connection parts (140a,140b). The upper horizontal member is formed into a size to be proportional to a distance between support columns. The lower horizontal member is positioned to be side by side in the lower side of the upper horizontal member. The vertical connection members connect the upper horizontal member to the lower horizontal member. The slope connection members connect the upper horizontal member to the lower horizontal member from a space between the vertical connection members. The connection parts separately connect both ends of the upper and lower horizontal members to the support columns. A connection part includes a main body, a secondary body, and a wedge unit. The secondary body is mounted on the main body. The wedge unit is formed with a slope part to be able to move in the wedge through-hole of the main body. The wedge unit allows the main body and secondary body to approach each other. |
