Description

Technical Field

[0001] This utility model specifically relates to a modular assembly system for stone curtain walls, belonging to the field of stone curtain wall technology. Background Technology

[0002] Stone curtain walls are typically installed using a dry-hanging method, which involves using metal hangers to fix the stone to the building structure instead of directly pasting it with cement. Dry-hanging methods include hanger-type dry-hanging structures, back-bolted dry-hanging structures, and keel + hanger systems. Dry-hanging is widely used in high-rise buildings due to its safety and durability. For example, Chinese Patent Publication No. CN119754464B discloses an installation structure and construction method for stone curtain walls. The installation structure includes a keel frame, mounting brackets, connectors, and stone panels. The outer side of the keel frame has a matrix-distributed cross plane, and the mounting brackets are fixed on the cross planes. This structure requires minimal manual connection, making installation convenient and rapid, significantly improving construction efficiency. However, in existing stone curtain wall construction, the process often involves installing each stone piece on-site, which is cumbersome and requires a large amount of manpower and time, resulting in a long construction cycle. This is especially true in high-rise or large-scale building projects, where progress is difficult to control. Furthermore, on-site installation is greatly affected by environmental factors such as weather and site conditions, making it difficult to guarantee the installation accuracy of each stone piece. This can easily lead to uneven joints, height differences, and other problems, affecting the overall aesthetics and quality of the curtain wall. In addition, traditional construction methods involve a lot of high-altitude work, posing high safety risks. Moreover, if local stone is damaged during later maintenance, it is often necessary to remove and replace a large area of ​​stone, resulting in high maintenance costs and difficulties. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a modular assembly system for stone curtain walls, which offers high construction efficiency and safer assembly.

[0004] The modular assembly system for stone curtain walls of this utility model includes: The unit frame is made of aluminum alloy profiles and includes two horizontal profiles and two vertical profiles. End brackets are fitted and fixed to the ends of the two vertical profiles, and the end brackets have splicing screw holes. The end brackets are fitted into the ends of the horizontal profiles. Corner brackets are pressed at the inner corners of the unit frame. One end of the corner bracket is tightened to the splicing screw hole by a bolt, and the other end is fixed to the vertical profile by a bolt. Guide rail grooves are integrally formed between the horizontal profiles and the corner brackets. Through holes are formed at both ends of the vertical profiles, and the through holes pass through the end brackets. A stone unit, comprising a stone body, a retainer fixed to the back of the stone body and slidingly engaging with a guide rail groove; the retainer is slidably engaged with the guide rail groove; the stone body has an outer hole facing the through hole; the inner diameter of the outer hole is larger than the inner diameter of the through hole. The mounting frame is composed of longitudinal beams and transverse beams spliced ​​together, and the longitudinal beams and transverse beams are fixed together by angle brackets; the mounting frame is fixed to the wall; the upper and lower sides of the transverse beams are integrally formed with a row of slots; the inner ends of the slots are provided with mounting screw holes; the unit frame is movably engaged with the slots; the inner side of the outer hole is embedded with a bolt body, which passes through the hole and is fastened to the mounting screw hole.

[0005] When installing a modular assembly system for stone curtain walls, the stone curtain wall units are assembled first. During assembly, the two end brackets of a vertical profile are embedded into two horizontal profiles and fixed with angle brackets to form an open unit frame. Next, the stone bodies are assembled sequentially into the open unit frame. Specifically, the brackets on the back of the stone body slide against the guide rail grooves until all stone bodies are assembled with the unit frame. Then, the two end brackets of another vertical profile are embedded into the other end of the two horizontal profiles to seal the unit frame. Plastic clips are placed between adjacent stone bodies to limit the gap between them. When the stone body is assembled into the unit frame, it needs to be bonded to the horizontal profile. Finally, the joints of the stone bodies are waterproofed. Next, the installation frame is fixed to the wall, and the stone curtain wall units are hoisted to their installation positions sequentially. The unit frame is embedded into the bracket grooves of the horizontal beams, and bolts are embedded into the outer holes. The bolts are tightened into the bolt holes to assemble the unit frame and bracket grooves into a single unit.

[0006] Furthermore, a rubber pillar is embedded inside the outer hole and coated with waterproof sealant. The rubber pillar and waterproof sealant can seal the outer hole and prevent moisture from penetrating into the bolt body.

[0007] Furthermore, a rubber sealing strip is provided between adjacent stone units or adjacent stone bodies within the same stone unit, and the rubber sealing strip is coated with waterproof sealant. The horizontal cross-section of the rubber sealing strip is a ⊥-shaped structure, the vertical edges of the rubber sealing strip are clamped between the stone bodies, and the horizontal edges of the rubber sealing strip are adhered to the back of the stone body. Through the rubber sealing strip and the waterproof sealant, the joints between adjacent stone bodies within the same stone unit, as well as the joints between adjacent stone units, can be completely sealed, improving the waterproof performance of the curtain wall and extending its service life.

[0008] Furthermore, an adhesive is applied between the card holder and the stone body; the card holder and the stone body are fixed by expansion bolts; the back of the stone body is bonded to the unit frame by adhesive; the card holder and the stone body are assembled into one piece using expansion bolts and adhesive, which can ensure the installation firmness of the card holder and the stone body and prevent the stone body from peeling off the installation position.

[0009] Furthermore, a back plate is provided on the inner side of the unit frame. The back plate is bonded to the back of the stone body, which can bond the individual stone bodies of the same stone curtain wall unit into a whole to form the entire support surface.

[0010] Compared with existing technologies, the modular assembly system for stone curtain walls of this invention has the following advantages: 1. Improved construction efficiency: Stone units can cover several times more area than single stone blocks. Moreover, the modular prefabrication and assembly of stone units greatly reduces the workload and construction cycle on site, thus improving construction efficiency. At the same time, factory production can better control product quality.

[0011] 2. Ensure installation accuracy: By accurately positioning and adjusting the installation method, the flatness and verticality of the stone curtain wall can be ensured, thus improving the overall quality of the curtain wall.

[0012] 3. Enhanced waterproof performance: The rubber sealing strips and waterproof sealant structure installed in the stone units themselves and between the stone units effectively prevent rainwater penetration, improve the waterproof performance of the curtain wall, and extend the service life of the curtain wall.

[0013] 4. Reduce safety risks: It reduces the amount of work required for working at heights on site and lowers the safety risks during construction. Attached Figure Description
