PSP Company
(Pars Structural Prefab)
It was established in 1357 in Shiraz and until now it has been active in the field of designing and implementing concrete and metal buildings with beam and block roofs, plain, prestressed and waffle concrete slabs.
Optimum use of materials and human resources and increasing the life of the building, waffle slabs are used as a suitable option in most residential buildings, office buildings, multi-storey parking lots, etc.
Pars Pretensioned Company has the honor of having a small share in the advancement of the country’s construction industry with the industrial production of PSP templates with patent number 3010428. The present collection is a brief overview of the use of two-way sign technology. In this collection, first the history and governing principles of this technology are stated, and then the equipment used, implementation steps and advantages of two-way signs are introduced.

Introduction and function of Dal Waffle
Double-sided waffle slabs are referred to as roofs in which empty holes are created in the roof to make it lighter. and the remaining concrete section, which weighs less than the full concrete section
Steps of implementation of Dal Waffle
1 – Molding under the ceiling
2- Installing PSP templates
3- Reinforcement
4- Concreting
5- Opening PSP formats
Technical advantages of waffle roof
1- Lower absorption of earthquake forces and improvement of seismic performance
2- Less rise of PSP roof in the long term than other similar roofs
3- Sound insulation and resistant to fire due to not using any plastic and polystyrene materials
Technical requirements and how to calculate PSP ceiling
Manual calculations of waffle slab according to ACI regulations are done like a simple concrete slab and with the help of ETABS software it will be possible to do these calculations.
Advantages of PSP waffle roof architecture
1- Implementation of long openings up to more than 12 meters due to the lightness of the waffle roof
2- Removing the suspension of the middle beams of the structure
3- The possibility of irregular columnarization
4- Ability to implement and install the Kenaf chassis on the PSP roof easily
Economic benefits of waffle roof
1- Reducing the weight of the building
2- Reducing the volume of rebar and foundation concrete
3- Reducing the thickness and volume of all shear walls
4- Reducing the volume and dimensions of all columns and beams
