Inorganic abrasive stone floor expansion joint elastic crack prevention insert device

Abstract

This utility model relates to the field of building materials technology and discloses an elastic anti-crack insert device for expansion joints of inorganic terrazzo flooring. It includes a floor body with a protective mechanism inside. A base is fixedly connected to the top of the protective mechanism, and sealing mechanisms are provided at both ends of the base. A cover plate is fixedly connected to the inside of the base. The protective mechanism includes an elastic buffer layer, and an isolation layer is fixedly connected to the bottom of the elastic buffer layer. A waterproof component for waterproofing is provided at the bottom of the isolation layer, and connecting blocks are fixedly connected to the inside of both sides of the elastic buffer layer. In this utility model, the elastic buffer layer absorbs thermal expansion and contraction stress with its highly elastic material, converting the stress into elastic potential energy, thus preventing the formation of floor cracks at the source. The connecting blocks ensure the buffer layer is stably stressed, preventing displacement failure. The isolation layer provides free expansion and contraction space for the buffer layer, extending the service life of the inorganic terrazzo flooring.
