Description

Technical Field

[0001] The utility model relates to the technical field of floor marble slab construction structures, in particular to a marble slab dry-hanging anti-falling structure. Background Art

[0002] In order to pursue the aesthetics of the building, the market will choose marble stone dry-hanging exterior wall for the exterior wall construction of the building. The basic construction process of marble stone dry-hanging exterior wall in the existing technology is: 1. First, the embedded steel belt is installed on the building structure through chemical bolts, that is, the embedded steel belt is placed during the concrete pouring construction of the beam body of the building, and then the vertical keel is connected to the embedded steel belt through channel steel connectors or welding; 2. All horizontal keels are cut and punched on-site with cold-dip galvanized angle steel, and then welded to the vertical keel; 3. After the construction of the vertical and horizontal keels is completed, rust and welding slag are removed on-site, and then paint and rust prevention treatment are done. Based on the above construction process, there are many technical problems: 1. The use of chemical bolts for construction will have a local impact on the original building structure, and it is easy to rust and break, causing the marble slab to fall off; 2. The welding of the horizontal keel and the vertical keel directly on the construction site has quality and safety risks, and the on-site cutting and punching of the galvanized angle steel and the welding machine processing will destroy the original galvanized protective layer of the horizontal keel and the vertical keel, causing the surface rust prevention to fail; 3. After the construction of the vertical keel and the horizontal keel is completed, the rust and welding slag are removed on site, and then the paint is applied for rust prevention. This design and construction process cannot guarantee the 30-50 years of service life of this keel structure, and the process has high quality and safety risks. Based on the above technical problems, the service life of the marble stone dry hanging exterior wall is low and the marble slab is prone to fall off, which in turn poses a high safety hazard.
