Wall Expansion Joints In Buildings

Expansion joints are separations between structures simply gaps to allow them to move and reduce stresses that may occur.

Wall expansion joints in buildings.

Often these gaps are filled with an expansion joint system to fill in the void to ensure walkability a complete building enclosure waterproofing and general serviceability of the structure. An expansion joint is designed to absorb safely the expansion and contraction of several construction materials absorb vibrations and permit soil movements due to earthquakes or ground settlement. The function of the expansion joints is to endure the stresses produced due to temperature variations. Expansion joints are one of the important joints used in construction like the roof expansion joints and in the paving slabs.

Interior and exteior expansion joint systems foam and compression seals and cutting edge fire barrier systems. Expansion joints can be incorporated into various building parts to provide complete separation like floors ceilings walls roofs and facades. The expansion joints are normally located between sections of bridges paving slabs railway tracks and piping systems. Expansion joint systems nystrom s expansion joints are manufactured to solve a variety of expansion joint scenarios.

Contraction and expansion joints limit the magnitude of forces and movements and cracking induced by moisture or temperature change by dividing buildings into individual segments. Find out which product works best for your project. We also provide facility protection products. 1 manufactured devices suitable for this application or 2 by field fabrication of suitable materials.

Joints can be planes of weakness to control the location of cracks contraction joints or lines of total separation between segments expansion joints. They can be placed floor to floor floor to wall wall to wall ceiling to ceiling ceiling to wall roof to roof or roof to wall. Expansion joints are usually only installed above dpc level and not below but must continue through any coping at the top of the wall. Expansion joint systems our expansion joint and fire barrier systems are egnineered to handle the unique conditions of your building.

Custom sizing materials and color finishes ensure that whatever you need for your project we ve got you covered. Flexible concrete expansion joints may reduce crack formation. The construction of the separation is accomplished by one of the following methods. Regarding the type of structural expansion joint most engineers agree that the best expansion joint and gener ally the most expensive is to use a line of double columns to provide a complete separation in the building frame at the joints.

As a general rule expansion joints should always be carried through the roofing membrane.
