Bracket Advantage

The brackets directly supported on the reinforced concrete columns are usually of the lower bearing type; the brackets supported on the steel columns are usually of the upper bearing type, and the height of the brackets should be based on the height of the supported truss end, rigidity requirements, economic requirements and Conducive to the principle of node construction to determine. Generally 1/5 ~ 1/10 of the span. The internode length of the bracket is generally 2m or 3m.

When the span of the bracket is greater than 18m, it can be made into a double wall type. At this time, the upper and lower strings are laid flat H-shaped steel to meet the requirements of the out-of-plane stiffness.

The bracket is a kind of truss.

The truss is triangular and trapezoidal, it is a flat system, one by one; the grid is a space system, is a whole.
