Description

Technical Field

[0001] The utility model relates to the field of stone decoration construction, in particular to a back-bolt type facade stone decoration dry hanging structure. Background Art

[0002] With the continuous development of the construction industry, curtain wall structures, as a crucial component of building envelopes, are undergoing continuous advancements in their design and installation technology. Stone is a commonly used curtain wall material, offering advantages such as natural beauty, durability, and widespread application in architectural design. Traditional stone curtain wall panels are installed primarily through dry or wet hanging. The dry hanging method uses adapters and embedded components to secure vertical studs to the structural wall. Horizontal studs are welded to the vertical studs, and dry hanging components are installed on the horizontal studs. Finally, the grooved stone panels are secured to the dry hanging components. This method results in high material costs for both horizontal and vertical studs, occupies a large space, and is slow to install. The wet hanging method requires drilling holes in the back of the stone, securing horizontal and vertical rebar to the wall with iron rings, then threading steel or lead wire through the holes in the stone and securing it to the horizontal wall reinforcement. Finally, cement mortar is applied in batches. This method is labor-intensive, and the cement mortar is more prone to hollowing and alkali reflux. Furthermore, the batched grouting process requires multiple curing cycles, increasing the workload and significantly extending the construction period.

[0003] Since the wet hanging method is relatively cumbersome to construct, the dry hanging method is generally used for construction. In order to improve construction efficiency, a dry hanging structure of stone without keels, such as that disclosed in CN104358376A, is used for construction to solve the problems of construction efficiency and construction cost. However, this type of structure has major defects during construction. Dry hanging parts are fixed to the wall with expansion bolts, and manual installation of expansion screws will result in inaccurate positioning and error accumulation. There is a large deviation between the installation position and the designed position of some dry hanging parts, which leads to the defect that the stone slab cannot be installed. Rework and repair will increase the workload and extend the construction period, which has a great impact on the construction progress. The utility model provides a back-bolt type facade stone decoration dry hanging structure to solve the above problems. Utility Model Content

The connecting grooves 41 are arranged corresponding to the connecting members 3. By arranging multiple connecting grooves 41 at intervals on the stone slab 4, a dry hanging structure is correspondingly arranged in each connecting groove 41, thereby stably fixing the stone slab 4 on the wall.

[0032] Furthermore, the upper and lower ends of the vertical plate of the connecting member 3 are respectively located in the connecting groove 41 of the upper stone plate 4 and the connecting groove 41 of the lower stone plate 4 .
