What Is a Truss Plate?

A truss made of steel bars for upper chords, lower chords, and web members connected by resistance spot welding is called a steel truss.

Reinforced truss floor bearing plate

The People's Republic of China Construction Industry Standard "Reinforced Truss Floor Bearing Plate" JG / T368-2012 ^[1]

Advantages: Mechanized production is achieved, which is conducive to the uniform spacing of the reinforcement bars,

Visual inspection and measurement: batch products should have a factory inspection certificate, the flatness of the plate should be less than 3mm, and there must be no obvious unevenness, distortion and distortion. The thickness of the galvanized layer should be greater than 120g / m2, and the surface of the plate must not be scratched or scratched, leaving Erbao welding slag. The solder joints should be opened firmly, and there should be no false welding, partial welding or missing welding. The surface of the product must be free of contaminants that affect the solidification of the cement. The packaging anti-rust plastic film must not be oxidized. Rebar diameter dimensions should meet the standards.

The "Reinforced Truss Floor Bearing Plate" was approved as the product standard for the construction industry, and the serial number was JG / T368-2012. It will be implemented from August 1, 2012. ^[2]

The current national standard for reinforced truss floor slabs is "Steel bar truss deck of the People's Republic of China Construction Industry Standard JGT368-2012".

This standard specifies the terms and definitions, markings and examples, materials, requirements, test methods, inspection rules, signs, packaging, transportation and storage of reinforced truss floor plates.
