Description

Technical Field

[0001] The utility model relates to the technical field of stone wall installation structures, in particular to a bidirectional fixed dry hanging structure of a stone aluminum honeycomb panel. Background Art

[0002] The stone aluminum honeycomb panel wall is composed of a stone facade and an aluminum honeycomb back panel. The traditional installation methods of the stone aluminum honeycomb panel wall include: dry hanging method, adhesive method and four-point support method.

[0003] In order to achieve the expected aesthetics, the installation error between the stone aluminum honeycomb panels is required to be no more than 2 mm. The traditional steel frame welding installation structure cannot be adjusted after fixing, which makes it very difficult to adjust the installation errors in the longitudinal and horizontal directions of the panels. In addition, problems such as undercut, slag inclusion, and deformation caused by steel frame welding will also affect the flatness of the wall.

[0004] The points of the traditional laying-out method are blocked in many places, which makes laying out extremely inconvenient. At the same time, due to the pattern and shape, it is also very difficult to collect data on the stone aluminum honeycomb panel using conventional methods. In addition, the prefabricated stone aluminum honeycomb panels need to be spliced ​​and assembled on site, which takes up space. Therefore, the BIM model can be introduced in the early prefabrication process, and BIM and laser scanners can be combined for acceptance in the later stage. There are also many technical difficulties in the process, which requires continuous experiments and research.

[0005] The construction of traditional stone aluminum honeycomb panels is complicated in technology, high in construction cost, inconvenient in installation, and low tolerance for manual operation. As a result, the actual construction is prone to quality problems such as uneven holes between the plate and the hanger, loose fixation of the hanger, deformation of components, loose bonding due to incorrect proportions or uneven application of epoxy resin dry hanging glue, and plate contamination. Since the dry-hanging stone aluminum honeycomb panel is fixed on the hanger in one direction, it is affected by thermal expansion and contraction, plate extrusion and the gravity of the stone itself, and there are hidden dangers of falling off, cracking and other safety issues. Therefore, in order to reduce hidden dangers and improve construction efficiency, it is necessary to optimize the links with quality problems and adopt more efficient construction methods.

[0006] Repair is a major difficulty in the construction quality management of traditional stone aluminum honeycomb panels, because the quality of the finished wall depends on the construction quality of epoxy resin dry hanging glue, welding parts, fixing parts and connecting parts. Repair is easy to cause damage to the above materials, overall stress instability of the surface layer, fatigue of welding parts and other problems, which will not only waste manpower and material resources, but also cause safety hazards. Therefore, it is necessary to adopt an installation structure that is easy to replace, safe and reliable, improve the installation quality and stability of stone aluminum honeycomb panels, and reduce maintenance costs.
