Geodesic domes Pakistan
incredible steel structure
Geodesic dome is a spherical space-frame construction made out of a complicated triangular network. At Jazari Steel, we craft domes that bring this globally recognized design to Pakistan
Dome History
In the year 1957, in Honolulu Hawaii, a geodesic dome was built so quickly it only took them 22 hours after all the parts/materials were delivered. Nowadays there is over 300,000 domes around the world
Space frame structure of dome
A truss system with member that lie in three dimensions.
Two usual forms of space frame
- Tetra-hedron (Three-sided pyramid)
- Half-octahedron (four-sided pyramid)
Geodesic Dome
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size.
In this type of structure, the shape of the shed will be in the semi hemispherical form. There will be a concrete wall up to a certain height from the ground level and the structure will be erected above this wall. The dome structure of various sizes could be adopted depending on the quantity of storage required
JAZARI Steel has capability to design, manufacture and install any diameter of geodesic dome in single and double layer space frame structure.
Process
Aluminum Domes Roof
The Aluminum Geodesic Dome Roof is an innovative modular free-spanning, a self-supporting structure that perfectly complements modular bolted containment and storage solutions. The design of the Geodesic Dome is such that it will fit onto both new and existing tanks, often without the need for the tank to be reinforced.
They are a fast and easy solution to install with the low weight of the aluminum structure giving decisive cost advantages when compared to other roof types.
The solution is elegant and gives maximum durability with minimal ongoing maintenance whilst providing environmental protection and a suitable means of odor control from the contents of a tank. The Domed Roof can be used on very large diameter tanks without the requirement for intermediate supports. The roof design offers excellent resistance to atmospheric conditions and is designed to withstand very high wind and snow loads which makes them an effective choice for weather protection. Utilizing an intelligent sealing system the design allows rapid and reliable construction in all types of construction conditions.
Installation
Grid Shell Structure
A grid shell is a lightweight, curved structure made up of a network of interconnected beams or rods, often arranged in a grid-like pattern. The beauty of grid shells is their ability to create large, stable forms using relatively few materials. They are often used in building designs to cover large spaces without needing heavy support columns or frameworks. Grid shells can be made from wood, metal, or other materials, and they typically feature a flexible and fluid design.
Engineering Characteristics for Dome
High strength
Bulk storage dome structures are highly durable and strong. If we talk about strength and average building life of dome structures, then their life is longer and strength is more than any other type of structure in Space frame industry.
Fireproof
After getting practical data of decades and performing the firelighter test, it is concluded that domes have excellent fire proofing capability than other similar structures.
Extremely Energy efficient
Dome structure does not need any interior support and thereby wide space inside them cater them the advantage of more storage.
Cost Effective & Good structural integrity
Dome structure comprises great structural tightness with minimal space & structural components and its geometrical shape gives an advantage to conserve energy in form of heat, which make dome structures cost effective.
Very Low Maintenance
Bulk storage dome structures are comparatively easier to maintain than any other building, therefore cost of maintenance on dome structures is lesser.
Good Acoustic Quality
In Most of the places where sound needs to travel in continuous manner, dome structures are preferable to other structures due to good acoustic nature of dome structures
Resistant to adverse weather condition
Due to its hemispherical Structure and absence of angles, flat surfaces make them highly resistant to adverse weather conditions such as Storms, Hurricanes etc.
Highly aesthetic and versatile
At Jazari Steel, we are one of the modern dome manufacturers use the combination of its basic features and latest technology to make dome structure more appealing and highly versatile in installation/reinstallation as well as in maintenance.
APPLICATIONS of Geodesic Domes
Petroleum & Gas
In the petroleum and gas industry, geodesic dome roofs provide essential protection for storage tanks, preventing evaporation losses and maintaining the integrity of stored products.
Chemical Storage
Ideal for storing various chemicals, geodesic dome roofs offer a leak-proof, durable cover that minimizes contamination and vapor loss, ensuring the safety and security of chemical storage facilities
Industrial & Renewable Energy
In industrial settings and renewable energy projects, geodesic dome roofs offer reliable storage solutions for raw materials, finished products, and biofuels, enhancing operational efficiency and safety.
Mining & Fire Protection
Used in mining operations and fire protection systems, these roofs ensure the safe storage of materials and chemicals involved in extraction processes and fire suppression activities
Advantages
Fast Installation
The design / manufacture / installation of geodesic dome structure can be accomplished with in a very short interval of time due to the use of pre-fabricated components.
Free Span (50m-200m)
Domes is more suitable for large span buildings from 50m to 120m because of its deflection &load bearing behavior against wind.
Eco-Friendly
These space frame structures are 100 % recyclable. Therefore, it is known to be eco-friendly.
Flexible design structure
It is one of the most flexible and sturdy structure used for constructing commercial buildings and residential properties.
Customized Shape & Height Structure
Space frame possess a versatility in shape & form and can utilize a standard module to generate various types of domes depends on the patter and height.
Light in weight
One of the most important advantages of Dome structure is its lightweight due to the uniform material load distribution spatially.
Light Civil Work Required
Dome structure required light foundation as compared to PEB structure. Thus, the cost of civil work for dome is very low because of light weight structure.
Less Deflection in Structure
Dome is the only space frame which has less deflection as compared to any other structure like PEB Structure or Truss system.
Accuracy in Installation
Another essential feature of using Space frames is that there is a high degree of accuracy in the process of designing and installation of space frames.
Future Displace to another Site
Dome is actually a nut bolt system, and we can disassemble and reinstall to another place.
Multi-Function Solutions
Domes the best option for Bulk storage and large space for large functions with free span (without column).
Low Maintenance
Space frame has low maintenance cost and suitable for coal storage sheds.
