What is the purpose of shoring and propping in construction?

Introduction

In the construction industry, ensuring the stability and safety of structures during the building process is of paramount importance. shoring and propping are two critical techniques used to provide temporary support to structures or parts of structures. This article delves into the purpose and application of these methods, offering insights into the specific parameters and the role of Kosun company in providing effective solutions.

Shoring in Construction

Shoring refers to the process of supporting a building, structure, or trench with shores (props) when in danger of collapse or during repairs or alterations. This technique is essential to maintain structural integrity and safety. Shoring is broadly used in situations such as deep excavations, building refurbishments, and remediation projects.

Types of Shoring

• Raking Shoring: Used to provide lateral support to walls. The incline should ideally be between 60° to 75°.
• Flying Shoring: A horizontal system that supports parallel walls, commonly used when construction is occurring between existing structures.
• Dead Shoring: Utilized to support vertical loads and is often employed when demolishing parts of a structure.

Key Parameters

• Load Capacity: Typically ranges from 20 kN to 200 kN per shoring unit.
• Material Strength: Steel is preferred due to its high tensile strength, typically 250 MPa, but aluminum is also used for lighter loads.
• Installation Angle: Optimum for raking shoring is between 60° to 75° to provide effective lateral support.

Propping in Construction

Propping is the process of temporarily supporting a structure or element until it can support itself or the permanent structural components are in place. Propping is crucial for the safety of workers and structural integrity during phases of construction and renovation.

Applications of Propping

• Temporary Support: During the installation of bridge beams and decks.
• Structural Remediation: In refurbishments, maintaining the integrity of floors and walls during repairs.
• Formwork Support: Assists in holding formwork in place during concrete curing phases.

Key Parameters

• Load Bearing Capacity: Propping systems can handle loads from 10 kN to 150 kN per prop.
• Prop Length: Adjustable between 1.5m to 5.5m to accommodate different construction requirements.
• Safety Factors: Generally, a safety factor of 1.5 is applied to account for unexpected stresses and ensure reliability.
