What is a black structure in construction Its components and importance in detail
Introduction
The black structure is one of the most important and dangerous stages of construction, because it represents the basic structure on which the entire project is built before starting any finishing or decorative works. The quality of the final finishes and the safety of the building depend on the accuracy of the execution of the black structure according to the correct engineering standards, which makes it the cornerstone of any residential or commercial project.
Any mistake at this stage can lead to serious structural problems that will be difficult to fix later, so the works of the black structure are of paramount importance in the world of construction.
Definition of the black structure
The term refers to The black hulk To all construction works that are carried out after the preparation of the land and before the start of finishing works. This includes all concrete elements and walls without any paints or finishing finishes.
The black structure is so named because it has a rough and unfinished appearance, where concrete and brick are visible without any aesthetic touches.
Components of the black structure in construction
The blackened structure consists of several main elements, and each element must be executed with high accuracy to ensure the safety of the building.
First: the upper foundations
The foundations are one of the most important elements of the black structure, they include:
- Armed bases after site processing
- Almeida or smilat
- طبقات العزل الخاصة بالأساسات (إن وُجدت)
The function of these elements is to transfer building loads to the soil in a safe and regular manner, preventing subsidence or future cracks.
Second: concrete columns
Columns are considered the backbone of any black structure, they are responsible for carrying floors and transferring loads to the foundations. It is carried out using:
- Rebar according to the schemes
- Wooden or metal wrenches
- Ready-mixed concrete or on-site mixed concrete
The quality of the execution of the columns directly affects the strength of the All-Black structure.
Third: Bridges (Bridges)
Bridges or girders are connecting elements between columns, serving to distribute loads in a balanced manner. The bridges within the black structure works are executed with high precision to avoid any future structural problems such as subsidence or cracks.
Fourth: concrete ceilings
Ceilings are one of the basic elements of the black structure, and they are performed depending on the structural system used, such as:
- Solid tiles
- The hurdy-gurdy system
- Flat slab system
The type of roof is selected based on the engineering design, the nature of Use, and the available budget.
Fifth: walls of buildings
After the completion of the concrete elements, the execution of the walls begins within the stages of the black structure using:
- Cement block
- Red brick
- Refractory or insulating brick
Walls help to divide the interior spaces and determine the architectural form of the building.
Sixth: internal infrastructure extensions
This stage of the black structure works includes the implementation of basic extensions before finishing, such as:
- Internal sewage lines
- Internal sewage lines
- Basic electricity extensions
- Air conditioning and communication sites
Accurately carrying out such extensions facilitates subsequent finishing works and prevents cracking and rework.
The importance of the black structure
The importance of the black structure lies in several key points, the most important of which are:
- Determine the strength of the building and its long-term safety
- Providing a strong foundation for finishing works
- Reduce future cracking or subsidence problems
- Ensure that the architectural design is executed accurately
- Direct impact on the final value of the property
Therefore, the quality of the execution of the black structure cannot be underestimated.
Black chassis quality standards
To ensure the implementation of a strong and safe black structure, several engineering standards must be adhered to, most notably:
- Full compliance with construction plans
- Use of approved concrete and materials
- Continuous Engineering Supervision
- Execution of works within the specified safety ratios
- Concrete testing and follow-up of rebar proportions
Compliance with these standards ensures obtaining a durable structural structure that will last for many years.
The difference between black structure and finishing
- Black structure: includes basic construction works only
- Finishing: includes aesthetic and functional works after the completion of the structure
Finishing can be started only after the complete completion of the black structure and its geometric inspection.
Conclusion
The black structure is the most important stage in any construction project, it is the foundation on which the rest of the stages are built. The more accurately and professionally the works of the black structure are carried out, the higher the quality of the building, the longer its shelf life, and the higher its market value.
