Description

Technical Field

[0001] The utility model relates to the technical field of wall construction in building engineering, and specifically relates to a back-bolt type connection structure for dry-hanging stones. Background Technique

[0002] In wall decoration, dry-hanging stones is a new construction process. Abandoning grouting and pasting, main stress points are set on the main structure, and then metal hanging parts are used to directly hang the stones on the steel frame in the air, forming a stone decorative curtain wall. Similarly, dry-hanging stones also have several different fixing methods, including plug-in type, grooving type, and back-bolt type. Among them, the back-bolt type is to precisely process the back of the stone with a hole-opening device, and the stone and the fitting are fixed through anchor bolts and screw rods, and then hung and fixed with the keel.

[0003] Chinese Utility Model Patent Publication No.: CN 219365092 U, discloses: a back-bolt type exterior wall dry-hanging stone construction structure. In this back-bolt type exterior wall dry-hanging stone construction structure, the lower plate is connected to the second sliding plate, and the ear hanging part is provided with a limiting plate to form a second sliding groove, which further ensures the alignment guidance during the installation of the dry-hanging stone and ensures that the overall structural strength is relatively high and the overall construction effect is good. However, this back-bolt type exterior wall dry-hanging stone construction structure does not have a alignment design for the vertical keel and the horizontal keel, which makes the vertical keel and the horizontal keel prone to displacement during installation, affecting the construction efficiency. Moreover, during the installation process of the installation part and the horizontal keel, it is only fixed by positioning bolts, which is prone to deviation during installation. At the same time, the contact area between the installation part and the horizontal keel is small, and the stability is poor. Summary of the Invention

At this time, tightening the third bolt enables the first hanging piece to be fixed to the installation component, improving the stability of the first hanging component.

[0015] Preferably, the second hanging component includes a second hanging piece, a guiding block, and an eighth threaded hole. A second hanging piece is inserted and installed inside the first hanging component. Guiding blocks are fixedly installed at the top and bottom of the second hanging piece.

At this time, the second hanging component is moved downward, and the second hanging component and the first hanging component are inserted and installed, so that the second hanging component can be hung inside the first hanging component, which is convenient for subsequent maintenance, disassembly and assembly. When installing the assembly component and the second hanging component, pick up the second hanging component, so that the guide block slides inside the guide groove. While positioning the assembly block and the second hanging component, the second hanging component can also move back and forth with respect to the assembly component to adjust the distance between the stone body and the second hanging component, thereby finely adjusting the overall angle to maintain the flatness between multiple stone bodies and improving the practicability. At this time, the eighth threaded hole overlaps with the limiting hole. By passing the fourth bolt through the eighth threaded hole and the limiting hole and tightening it, the assembly block and the second hanging component can be fixed, improving the stability of the assembly block and the second hanging component.
