Double angle steel rod in the corners of the roof steel why need to set the plate?
Pad is used to pad something to make it more convenient and comfortable things, commonly used in the examination to avoid paper directly on the table caused by writing difficulties of the board, are usually hard paper. In architecture, a plate member between the upper and lower two upper and lower two purlin Fang or architrave, thickness is usually a fight.
A rod is a member of a much larger dimension than a horizontal (vertical) direction. The beams, columns and other components in the building are generally abstracted as rods. The shape and size of the rod can be described by two major geometric elements, the cross section and the axis of the rod. A cross section is a vertical section perpendicular to the length of the bar, and the axis is the center of each cross section. The cross section and the axis of the rod are perpendicular to each other. A rod with the same axis and straight line and cross section is called a straight rod with equal section. Building mechanics and mechanics of materials are mainly concerned with equal section straight bars. The bar whose cross section changes along the axis is called a cross section bar.
Double angle truss rod set in which plate in the corners between the steel is mainly to increase its stiffness.
