Brick meshing, also known as brick reinforcement mesh or masonry mesh, is used to reinforce brick structures by adding strength and stability. This simple yet effective material plays a crucial role in modern masonry construction.
Understanding Brick Meshing
At its core, brick meshing is a type of reinforcement specifically designed for use within the mortar joints of brickwork or blockwork. It typically consists of thin steel wires welded together to form a ladder-like or truss shape.
Purpose and Function
The primary function of brick meshing is to improve the structural integrity of walls. By embedding the mesh within the horizontal mortar courses, it helps to:
- Increase Tensile Strength: Masonry is strong in compression (carrying weight from above) but weak in tension (forces that pull it apart). The steel mesh provides crucial tensile strength to the wall.
- Prevent Cracking: It helps distribute stresses throughout the wall, significantly reducing the likelihood of cracks forming due to settlement, thermal movement, or minor ground shifts.
- Improve Stability: The mesh ties the bricks or blocks together more securely, enhancing the overall stability and rigidity of the wall.
- Enhance Load-Bearing Capacity: While not the primary load-bearing element, reinforcement contributes to the wall's ability to withstand various forces.
How it is Used
Brick mesh is installed horizontally during the construction of a wall. As each course of bricks or blocks is laid, a strip of the mesh is placed on top of the mortar bed before the next course is added. The mesh is then fully embedded within the mortar joint as the next course is laid.
Common types of brick mesh include:
- Ladder Mesh: Features two parallel wires connected by perpendicular cross wires, resembling a ladder.
- Truss Mesh: Has two parallel wires connected by diagonal wires, forming a truss pattern.
The choice of mesh type and material (often galvanized steel for corrosion resistance) depends on the specific requirements of the structure and environmental conditions.
By integrating brick meshing into the mortar joints, builders create a composite structure where the strength of the steel reinforcement complements the compressive strength of the masonry units, resulting in a more durable and resilient wall.
