Expansion Joints in Architectural Structures
Expansion Joints
Expansion Joints are the structures which used to absorb the thermal expansion and thermal contraction of building materials caused by heat. In order to avoid these issues Expansion Joints are used. Expansion joints are also called Movement Joints. Those are a bellows type device. It also avoids the issues caused by vibration, seismic activity and to allow movement caused by ground settlement. There are different types of expansion joints with variety of applications.
Importance of Expansion Joints in Architectural Structures
It is important to confirm the safety and durability of buildings during construction. Today the buildings are constructing in an attractive manner. Building's designs, construction and decorating methods are changing day by day. Now most of the buildings are constructed by utilizing natural resources like wind and sunlight. Buildings structures expand and contract according to the climate changes. Thermal contraction of building materials occurs in cold weather and expansion occurs when it is hot weather. Thermal stress varies according to weather changes. To avoid these types of issues Expansion Joints are needed. Expansion Joints can effectively manage the variations and control problems due to vibration, it also hold the building materials together and allow the movement of materials due to earthquake. These joints are placed where a slab meets the building, where a slab meets another slab etc.
