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 will be responsible for formulating and revising: GB/T 42355 aims to standardize the classification and ordering of anchor plates for reinforced concrete

Contents, technical requirements, process inspection, test methods, inspection rules, etc:, 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 is to specify the test method applicable to the reinforcement of the anchor plate of the concrete structure:

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 2: Test methods

1 Scope

This document describes load transfer tests, stability tests of joints and test reports for anchorage slab reinforcement in concrete structures:

This document applies to anchorage plate reinforcement for reinforced concrete:
