Interlocking building blocks are a versatile construction material with applications in architecture, engineering, and education. This beginner’s guide covers everything you need to know about interlocking blocks – from key terminology to real-world uses.
An Introduction to Interlocking Blocks
Interlocking building blocks, sometimes referred to as interlocking bricks or concrete blocks, are unique construction pieces designed to fit snugly together without mortar or cement. The blocks connect using protrusions and indentations that securely join each unit, allowing stable wall assemblies and structures to be created.
Interlocking blocks are used to construct both load bearing and non-load bearing walls and partitions. Their interlocking mechanism gives greater structural integrity and insulation compared to traditional bricks. Interlocking blocks are also lightweight and easy to assemble, making DIY building projects simpler.
Key Terminology
Here are some key terms related to interlocking blocks:
- Interlocking: Fitting together securely, often used to describe the connectivity of building blocks
- Building blocks: Construction pieces for creating structures and enclosures
- Wall assembly: The process of stacking courses of blocks to build a freestanding wall
- Staggered block courses: Laying each row of blocks so that the vertical joints are offset from the rows above and below for better stability
- Load bearing: Supporting structural loads like floors, ceilings and roofs
- Non-load bearing: Not carrying weight but used as enclosures and partitions
- Masonry: Structures built from individual units like stone, brick or concrete block
- Construction system: Method by which structures are assembled from standardized components
Understanding these terms will help you better grasp how interlocking blocks are used.
Real-World Applications
Interlocking blocks have many useful applications in building and construction:
- Walls and partitions – Stacked in courses as masonry enclosure systems and space dividers
- Floors and ceilings – Assembled as raised floors over basements or recessed ceilings
- Roofs – Pitched roof assemblies rely on interlocking blocks
- Insulation – Built-in protrusions create air cavities that insulate against heat/cold
- Flood protection barriers – Interlocking blocks are used to quickly assemble barriers against rising flood waters
- Retaining walls – Both small landscaping retaining walls and tall structural walls rely on interlocking blocks
In many cases, interlocking block assemblies require no mortar, allowing faster construction using a dry-stack method. The blocks are simply stacked and interlocked together leveraging their protrusion/indentation system.
Structural Considerations
Interlocking blocks can be used to create both load bearing and non-load bearing walls:
- Load bearing – Stacked blocks can safely carry vertical weight from floors and roofs above based on their compressive strength. This allows the construction of multi-story buildings using interlocking blocks as support elements.
- Non-load bearing – Free-standing or partition walls that do not carry any load. These divider walls rely only on the interlocking mechanism to remain stable without mortar/cement.
Understanding these structural considerations allows proper assessment of appropriate applications for interlocking blocks – whether load bearing walls, room partitions, or independent fence and barrier structures.
Interlocking Building Blocks in Education
Beyond commercial building applications, interlocking blocks also have some unique uses in education:
- Chemistry modules – Specially designed interlocking blocks help high school students visualize molecules and chemistry concepts through hands-on assembly of molecular structures
- Physics models – Frictionless movement of interlocking block assemblies allows models of mechanical physics concepts like mass, velocity and energy loss
- 3D design projects – Open-core blocks with custom exterior shapes enable students to design intricate 3D art sculptures, architectural models, etc.
Educational interlocking building blocks cater to kinesthetic and visual learning styles through manipulation of physical objects to impart key concepts.
Innovative Variants
Standard rectangular interlocking blocks are not the only option available today. Some interesting modern variants include:
- Assemblable stones – Interlocking blocks shaped and textured like natural stones allow realistic stone facing walls to be assembled quickly and easily
- Soundproof blocks – Special sound deadening materials like mass loaded vinyl sandwiched within interlocking blocks help create soundproof interior partitions
- Decorative blocks – Blocks with custom decorative finishes give high-end aesthetic appearances for reception area dividers or displays
- Giant blocks – Oversized interlocking blocks measuring 3 feet or more across for very rapid assembly of large structures like flood barriers
This is just a small sampling of the diverse interlocking block styles available. Customization allows almost any size, shape or configuration imaginable today!
Interlocking Building Block Patent
A key patent related to interlocking building blocks is the Interlocking Building Brick filed with the USPTO and EPO. This invention filed by ecoBloc describes a brick featuring:
