Expansion joint types

Flexible Piping Solutions from Flexicraft Industries. Learn why Meadows solutions are trusted by architects and contractors worldwide! What are the different types of expansion joints? What is the common use of an expansion joint?

Bridge expansion joints are designed to allow for continuous traffic. Clay bricks expand as they absorb heat and moisture.

Usually, expansion joints are not provided in the railways. Other expansion joint types. Below, we have compiled types of expansion joints offered at Holz Rubber. The basic type of expansion joint.

For this type, thrust generated by internal pressure is applied to the fixed points. If high internal pressure is applie a reinforcement ring is used to prevent deformation of the bellows. There are other terms in use for expansion joints such as expansion bellows, flexible joints and compensators.

A typical expansion joint is comprised of one or more metal bellows (most commonly stainless steel ) or from materials such as rubber, fabric or plastic such as PTFE.

We constantly innovate and incorporate the latest technology to protect commercial buildings from damage due to fires and movement from thermal expansion , wind or earthquakes. Prior to selecting an expansion joint cover for a project, it is crucial to consider which type(s) of movement a building may be subject to. This joint is a perimeter joint.

A control joint is an intentionally weakened break in a concrete surface to allow. ISOLATION OR CONSTRUCTION JOINT. This joint is similar to a control joint in. This is a planned for and.

In modern expansion joints, the metal bellows are often produced with a so-called multi-ply design. To increase both flexibility and stability, multiple thin plies of metal are layered to form the bellows walls. There are two basic design types : The multi-ply and the multi-walled bellows structure. The concrete is subjected to volume change due to many reasons. So we have to cater for this by way of joint to relieve the stress.

The building longer than 45m are generally provided with one or more expansion joint. High resiliency with excellent recovery after compression. Expansion Joints and Construction Sealants.

Protects against water infiltration when properly sealed. It allows for thermal expansion and contraction without inducing stress into the system.
