Wall posts, Galvanized Bed Bars, and Threshold Shoes

Most of the earthquakes in the world occur on strips called seismic belts. Considering that Iran is located on one of these belts (Alpide Belt) and has experienced several devastating earthquakes, lessons and results have been learned that ultimately led to the formation of the sixth edition of the 2800 standard for seismic design and execution of non-structural architectural elements. According to the regulations of this standard, non-structural architectural elements such as wall posts, threshold shoes, and galvanized bed bars have been used in the internal partitioning to prevent possible movement of walls during earthquakes and also to prevent corrosion of iron in humid conditions on Kish Island. In this project, walls have been designed and executed as non-continuous elements, meaning that they are separated from the main structure.
Galvanized H-shaped bed bars have been used as a support for walls longer than 4 meters in length in the pallets, which despite being connected to the floor and ceiling, move longitudinally freely during earthquakes. Another application of these supports is separating walls from each other at the intersection of two walls. The connection of the wall to the ceiling or beam is a sliding connection without direct connection and through galvanized anchor bolts in such a way that the wall can move completely freely. These bolts are anchored to the structure every 80 cm along the wall. To prevent cracks after loading and the return of the beam to a neutral state, polystyrene with a thickness of 3 cm and a width of 15 and 10 cm has been used on these materials in a thin layer with one layer of Rabits.
In this project, Leca three-sided blocks with outstanding features such as low weight, high speed, sound insulation, and heat and moisture insulation have been used. Due to the use of Leca ready-mix, which has very good compatibility with weather conditions and Leca blocks and has high elasticity and adhesion properties, a reinforcing element called galvanized bed bars has been used in each of the three rows of blocks to reinforce the walls. In the row where these bed bars are located, the formwork will overlap freely with the bed bars using anchors. It should be noted that screw and bolt and anchor bolt connections have been used in all connections, and welding connections have been avoided. Galvanized threshold shoes with a thickness of 3 mm have been used to control the loads on glass walls in some of the master, mandatory, and threshold door bathrooms.
