Description

Technical Field

[0001] This invention relates to aluminum alloy grille installation components and methods for stone curtain walls. Background Technology

[0002] Currently, aluminum alloy decorative strips can only be fixed to stone curtain wall panels using chemical methods such as structural adhesives. However, this construction process does not meet the required standards and poses significant safety hazards. As a result, aluminum alloy decorative strips cannot be installed on the outer surface of the stone curtain wall, thus failing to achieve the desired decorative design effect.

[0003] Current technology only allows aluminum alloy decorative strips to be bonded to the outer surface of stone curtain walls using structural adhesives. However, curtain walls are highly susceptible to external influences during use, and the structural adhesives used for bonding are prone to aging, losing elasticity, and becoming brittle. This poses a significant safety hazard to the bonded aluminum alloy decorative strips during curtain wall use. Therefore, regulations prohibit the bonding of decorative components to the outer surface of curtain walls. This means that current technology cannot achieve a tight fit between the aluminum alloy decorative strips and the stone panel surface, failing to meet the architect's design requirements.

[0004] To effectively address the problem that existing technologies cannot install aluminum alloy decorative strips on the surface of stone curtain walls, a specialized structural design is adopted to achieve convenient, reliable, and secure installation of aluminum alloy decorative strips on the outer surface of stone curtain walls, satisfying decorative design effects while ensuring safe use.

[0005] To achieve specific decorative effects, solid curtain walls typically feature aluminum alloy decorative strips attached to their outer surface, usually arranged vertically or horizontally. For aluminum single-panel curtain walls, these strips can be directly attached to the aluminum panel surface using self-drilling screws or rivets. However, for stone curtain walls, due to the brittle nature of stone, nails cannot be driven into the stone panels, making it impossible to install aluminum alloy decorative strips on the outer surface. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an aluminum alloy grille installation component and method for stone curtain walls.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0008] An aluminum alloy grille installation component for stone curtain walls includes stone panels and aluminum alloy decorative strips;

[0009] The aluminum alloy decorative strip includes an aluminum alloy pressure plate and an aluminum alloy decorative buckle cover that is fastened to the aluminum alloy pressure plate; a sealing rubber strip is filled between the bottom surface of the aluminum alloy pressure plate and the outer surface of the stone slab.

[0010] The aluminum alloy pressure plate is provided with a rubber strip groove and a long strip hole for inserting a sealing rubber strip.

[0011] When laying out and prefabricating stone slabs, firstly, lines are laid out on the back of the stone slabs according to the installation positions of the aluminum alloy decorative strips; then, T-shaped grooves are milled on the back of the stone slabs; secondly, through holes are drilled in the stone slabs at the center of the T-shaped grooves, with the through holes corresponding to the installation axis of the aluminum alloy decorative strips.

[0012] Before installing the stone slabs, use epoxy resin adhesive to bond threaded nylon connectors to pre-drilled square countersunk holes on the back of the stone slabs.

[0013] A method for installing aluminum alloy grilles on stone curtain walls, using aluminum alloy grille installation components for stone curtain walls, the components including stone panels and aluminum alloy decorative strips;

[0014] Step 1: Pre-fabricate the stone slab layout. First, mark the lines on the back of the stone slab according to the installation position of the aluminum alloy decorative strip. Then, mill a T-shaped groove on the back of the stone slab. Next, drill a through hole in the stone slab at the center of the T-shaped groove, with the through hole corresponding to the installation axis of the aluminum alloy decorative strip.

[0015] Step 2: Install the stone slabs by using epoxy resin adhesive to bond the threaded nylon connectors to the pre-made square countersunk holes on the back of the stone slabs.

[0016] Step 3: After the stone panels are attached, first, fill the gaps between the stone panels with foam rods B and apply silicone weather-resistant sealant; then, insert stainless steel screws B into the elongated holes of the aluminum alloy pressure plate and connect them to the stone slab through holes and nylon connectors on the stone panel; finally, fasten the aluminum alloy caps onto the aluminum alloy pressure plate to complete the installation and fixing of the aluminum alloy decorative strip.

[0017] This invention involves welding L50*5mm thick angle steel connectors (hot-dip galvanized) to 10# hot-dip galvanized channel steel columns connected to the structure. The L50*5mm thick angle steel connectors (hot-dip galvanized) have elongated holes. M8*30 stainless steel bolts are used to connect L50*50*5mm hot-dip galvanized angle steel horizontal keels to the L50*5mm thick angle steel connectors (hot-dip galvanized). Then, M8*30 stainless steel bolts are used to connect 4mm aluminum alloy stone hanging parts to the fixed L50*50*5mm hot-dip galvanized angle steel horizontal keels. The position of the stone is adjusted through the elongated holes according to the drawings, and then fixed securely. When laying out the stone at the processing plant, lines are drawn on the back of the stone according to the installation positions of the aluminum alloy decorative strips. T-shaped countersunk grooves are milled on the back of the stone, 6mm deep, with a spacing not exceeding 600mm. Simultaneously, a through hole is drilled in the center of the countersunk holes, with the center of the through hole aligned with the installation axis of the aluminum alloy decorative strip. Before installing the stone panel, threaded nylon connectors are bonded to the square countersunk holes on the back of the stone using epoxy resin adhesive. Because the nylon connectors are flexible, the connection will not damage the stone panel. 7mm wide grooves are cut on the top and bottom sides of the 30mm thick stone. According to the construction drawings, the aluminum alloy S-shaped and E-shaped hanging parts are installed on the top and bottom sides of the stone and fixed with epoxy resin adhesive. The 30mm thick stone is then hung on the installed 4mm aluminum alloy stone hanging parts according to the installation design requirements. The height of the 30mm thick stone is adjusted using M5 adjusting screws. After the stone panels are positioned, ∅8 foam rods are inserted into the gaps between adjacent stone panels and sealed with special weather-resistant sealant for stone. A sealing rubber strip is then inserted into an aluminum alloy pressure plate with elongated holes. M5*50 stainless steel screws are then screwed through the elongated holes in the aluminum alloy pressure plate and the round holes in the stone panels, and into the threaded holes of the 25*25*6 nylon connectors on the back of the stone panel. This fixes the aluminum alloy pressure plate to the installed stone curtain wall panel. Finally, the aluminum alloy clip is fastened onto the aluminum alloy pressure plate installed on the stone panel, completing the installation and fixing of the aluminum alloy decorative strip. This invention employs a specially designed structure that solves the problem of not being able to directly nail aluminum alloy decorative strips to stone panels, and the low safety and reliability of using adhesive aluminum alloy decorative strips, which is not permitted by regulations. This allows for convenient and quick installation of aluminum alloy decorative strips on the outer surface of stone curtain walls, achieving both decorative effect and meeting safety requirements. This invention is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use.
