introduction
GB/T 42355 "Anchor Plate Rebar for Reinforced Concrete" is a sub-technical committee of Steel for Reinforced Concrete of the National Steel Standardization Technical Committee
It is one of the steel bar series standards that the Committee (hereinafter referred to as the "Committee") is responsible for formulating and revising: GB/T 42355 aims to standardize anchor plates for reinforced concrete
The classification, order content, technical requirements, quality inspection, test methods, inspection rules, etc: of steel bars are composed of two parts:
--- Part 1: Technical conditions: The purpose is to specify the technical requirements for anchorage plate reinforcement for reinforced concrete structures:
--- Part 2: Test methods: The purpose of this specification is to specify methods of test for anchor plate reinforcement for reinforced concrete structures:
These two parts of the standard are complementary to each other, the first part belongs to the product standard, and the second part is the test verification method of the first part:
Anchor Plate Rebar for Reinforced Concrete
Part 1: Technical conditions
1 Scope
This document specifies the symbols, technical requirements, classification, quality inspection, and production requirements for anchor plates and anchor plates for reinforced concrete structures:
requirements, test requirements:
This document applies to anchor plates and anchor plates for reinforced concrete:
This document does not apply to products where the ends of bars and bars or other steel members perpendicular to them are anchored by field welding:
