1, post-cut anchor bolt dry hanging method (back bolt dry hanging method)
Back-bolted dry hanging, also known as back-cut backbone hanging with a dragon, is a kind of stress-free connection structure with surface contact, which is to accurately process a plurality of conical round holes on the back of ceramic plates through professional drilling equipment, implant anchor bolts into the conical holes, screw in screws, and make the bottom of the anchor bolts unfold and closely combine with the conical holes, and then fix the ceramic plates on the mounting keel through connectors. Compared with the traditional bolt-type and buckle-groove-type dry-hanging system, the back-bolt-type dry-hanging system has simple and clear stress, no stress concentration caused by interconnection, smaller bending moment of plates and higher safety, and is more suitable for super-high-rise or earthquake-resistant structures. In terms of installation and construction, the plates are installed independently, with high prefabrication degree and convenient construction. In addition, the replacement of plates is more convenient, which can reduce the maintenance cost of curtain wall. On the basis of back-bolted dry-hanging system, new and more reliable connection technologies such as two-section seismic back-bolted dry-hanging system and back-grooved dry-hanging system have been successfully developed and gradually applied in practical projects.
2. Butterfly stacking construction technology
Butterfly layout construction technology belongs to the trough dry hanging method in Zhang Yihong, commonly known as trough dry hanging method. Through professional grooving equipment, it accurately processes a long slot on the side of the plate, implants the teeth of the toothed plate into the slot, and fixes the plate on the installation base surface through the connector. Compared with the pin-type point anchorage method, the short-slot dry-hanging technology has greatly improved safety performance due to the partial anchorage of Ayong. However, there are also fatigue problems of the upper and lower toothed plates and elastic fasteners, and it is only suitable for building curtain walls with a certain height.
3. Butterfly short code construction technology
The construction technology of butterfly short yard belongs to a kind of trough dry hanging method, commonly known as short trough dry hanging method. Through professional grooving equipment, it accurately processes a groove on the side of the plate, and the teeth of the toothed plate can be easily inserted into the groove, and the plate is fixed on the installation base surface through the connector. Compared with pin-type point anchorage, the short-slot dry-hanging technology greatly improves the safety performance because it adopts partial edge anchorage, but it also has the fatigue problem of upper and lower buckle toothed plates and elastic fasteners, and is only suitable for curtain walls with a certain height.
4. A T-shaped dry hanging method with back groove.
The supporting system of the system has less keel consumption, simple installation process and high installation efficiency. The cost of this system is lower than that of L-shaped and C-shaped curtain wall systems. Throughout the evolution and development history of curtain wall technology, dry hanging is widely used and the technology is constantly updated, especially new technologies such as post-cutting anchor bolt dry hanging method and post-cutting groove dry hanging method are constantly adopted.
It has the advantages of uniform stress, corresponding strength and good stability, long service life, convenient construction and later maintenance, and good decorative orientation effect, which makes it stand upright on the exterior wall facing of high-rise and super-high-rise buildings.
5, T welding specification construction technology
T-type welding code construction technology belongs to one of the methods of slope dry mouth hanging, commonly known as short slope dry mouth hanging method Through professional grooving equipment, it accurately processes a groove on the shift side, implants the T-shaped pendant into the groove, and fixes the plate on the installation base through the connecting rod. Due to the partial support edge anchorage in Ayong, the construction technology of T-shaped welding specification greatly improves the safety performance compared with the pin-type point anchorage method, but it also has the fatigue problem of upper and lower toothed plates and elastic fasteners, and is only suitable for building curtain walls with a certain height.
6, steel pin split dry hanging method
Later, the steel needle style gradually swept the world and rose in Japan in the 1980s. It uses an impact hammer to punch round holes on the upper and lower sides of the plate, which is easy to cause cracking during processing. When the plates are connected by steel pins, the steel pins are inserted into the upper and lower plates, and the mutual fixation from top to bottom is continuous. When any one of them is damaged, it cannot be replaced separately, and it needs to be removed from the top to replace it, which is labor-consuming and time-consuming, and may also affect the normal use of the building. In China, the steel pin type was also used in the early stage, but its development was greatly limited due to the safety problems and high cost caused by layer-by-layer stress.
