Ehitusühiku

Ehitusühiku is a type of joint used in post-tensioned concrete construction, specifically in the tendon anchorage system. It is a mechanical bond that provides a secure connection between the prestressing tendon and the surrounding concrete.

The ehitusühiku joint is typically used in building foundations, walls, and slabs where high tensile forces are applied. It consists of a specially designed metal device that is embedded in the concrete, allowing the tendon to be securely anchored and prestressed. The joint is typically rectangular in shape and measures a couple of centimeters in size.

Ehitusühiku joints are designed to handle large tensile forces and maintain the pre-stress in the tendon over time. They are commonly used in building structures that require high levels of stability and resistance to external loads. The joint is designed to withstand various types of loading, including vertical and horizontal forces.

One of the key benefits of ehitusühiku joints is their ability to prevent tendon slip and ensure consistent pre-stress distribution. This can help to reduce concrete cracking and improve the overall durability of the structure. Ehitusühiku joints are also relatively easy to install, as they can be prefabricated and installed on-site without requiring complex anchoring systems.

Overall, ehitusühiku joints are an important component of post-tensioned concrete construction, providing a secure and reliable connection between tendons and concrete. They are widely used in the construction industry for building a range of structures, from residential buildings to large commercial units.
