History of waffle roof in Iran
In order to answer the question of what is a waffle roof and its history, we must refer to our history. It is interesting to know that the idea of ​​two-way cargo goes back to the Achaemenid period, about 2500 years ago. According to the remains and according to the analysis of archaeologists, the roof of Persepolis was made of perpendicular wooden beams. Also, the idea of ​​using the function of the waffle roof can be seen in the building of the Acropolis of Greece, the same period as the Achaemenians.

Waffle roof implementation method
The implementation of the waffle roof has such a stage. Briefly, we describe each of these steps below. Among these steps, we can refer to the underlaying of the waffle roof, porcelain mold, reinforcement, concreting, mold removal and carpentry operations.
Implementation of the waffle roof
Waffle roof underlayment operation
The first step of implementing a waffle roof is the foundation operation, which begins with the installation of jacks and continues with the use of waffle molds. But what is the difference between a beam roof and a waffle roof? Installation of jacks is done like a block beam roof and there is no need for a metal mold because the waffle molds are placed directly on the metal cans and provide all the space needed to keep fresh concrete. . Of course, it is not without grace to know that in the informal modification of waffle roof engineers and contractors, this stage will also be called the chassis drawing stage. In fact, this step prepares the ground for arranging the waffle molds according to the plan of the Chinese mold.

After placing the waffle molds, rebar and reinforcement operations begin. During rebar installation, the passage of executive agents is done without any problems. Because the molds have high strength. Of course, this feature is very important during execution. Due to the easy movement of workers, the time of the roof will definitely be shorter. After the strength of the structure, this is the second factor that the Zagros team makes possible by implementing the waffle roof.
Waffle roof concreting
After the final controls, the concreting operation is done and if desired, the upper surface is completely polished. This work can be done using a butterfly trowel. Although this increases the beauty and quality of the work, it is not necessary.
Waffle roof molding stage
After the time has passed and the curing process is completed, the concrete hardens and the molding operation is done. At this stage, care should be taken so that the molds do not get stuck in the concrete and do not crack when they are pulled out. Because waffle molds are reusable, it is recommended to be very careful in maintaining them.

Waffle joinery operation
Joinery is the final stage of the roof. In some halls and rooms, false ceilings are used at this stage. On the other hand, in some halls, the roof view is used as an exposed and final view, which can be used with eye-catching lighting and designs.
What are the essentials of waffle roof design?
Today, waffle roof design, like other design issues, is done with the help of software and based on regulations. Safe and Etabs software are usually used to design this structure. There are different guidelines for designing regulations. In Iran, there is a unified procedure in this regard, and the design should not be done according to taste.
