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
