Wall strength with bed rebar
Bed rebar is a simple but powerful element in the construction of walls, which plays a vital role in increasing their strength and stability, especially against earthquakes and wind. In this article, we will discuss the comprehensive review of bed rebar, its advantages and disadvantages, how to implement and important points in its use.
What is bed rebar?
The bed rebar is a wire or ribbed rebar with a diameter of 4 to 6 mm, which is placed in the mortar between the ridges of the wall. By creating integrity in the wall, this rebar significantly increases its resistance against lateral forces such as earthquakes and wind.
Advantages of using bed rebar:
Increasing wall resistance: The bed rebar prevents cracking and destruction by restraining the wall against lateral forces.
Reducing the probability of the wall falling: By increasing the cohesion of the wall, the bed rebar significantly reduces the probability of its falling during an earthquake and wind.
Increasing the lifespan of the wall: By increasing the strength of the wall, the bed rebar also increases its lifespan.
Reducing cracking: By creating integrity in the wall, the bed rebar prevents it from cracking and being damaged due to settlement and movement of the building.
Easy implementation: the bed rebar is easily placed in the mortar between the wall ridges and does not require special expertise and skills.
Disadvantages of using bed rebar:
A slight increase in the cost of construction: the use of bed rebar can slightly increase the cost of building a wall.
Rust: If you don't use galvanized or stainless steel bars, there is a possibility of the bed bars rusting in humid environments.
How to implement bed rebar:
Choosing the right rebar: The bed rebar should be selected according to the thickness of the wall, the type of material and the amount of incoming loads.
Placing the rebar in the mortar: The bed rebar must be placed in the mortar between the wall ridges and horizontally.
Connection of rebars: The rebars of the bed must be connected to each other at the intersection of the walls and corners.
Rebar coating: The bed rebar should be completely covered in mortar to prevent rusting.
Important points in using bed rebar:
Use of high-quality materials: high-quality materials must be used for the implementation of bed rebar.
Adherence to technical standards: The implementation of bed rebar must be done in accordance with technical standards and national building regulations.
Engineering supervision: The implementation of bed rebar must be done under the supervision of the supervising engineer.
