technical field

The invention belongs to the technical field of architectural decoration, and particularly relates to a back-bolt type stone dry hanging quick-installation connection system.

Background technique

At present, most of the decorative materials such as stone and ceramic tiles on the market are fixed on the wall by means of steel skeleton keels, but the construction progress and cost are relatively high. The keelless dry hanging system has great advantages in terms of cost and space saving.

Because the traditional installation method requires a steel skeleton, which results in a lot of waste of space, and the traditional dry hanging uses stone glue to bond with the pendant, the strength is relatively weak for a long time, and the veneer layer is easy to loosen and fall off, causing a great safety hazard.

For the assembly of stone without keel, there are also structures in the existing stone assembly structure that use pendants for installation, but in use, they are generally assembled by means of combination hanging. In specific construction, this kind of pendant can only Adjust the level of the stone, but due to the characteristics of the wall surface, such as unevenness, inclination, etc., the uneven appearance of the stone is prone to appear when the stone is hung, and it still needs to be properly leveled during on-site construction. Leveling involves not only height leveling, but also a certain degree of inclination leveling, so as to ensure that the stone is relatively flat after installation, so that the junction of the stone is aligned. Based on this, a back-bolt type stone dry Hanging quick connect system is necessary.
