Glass Curtain Wall Architecture
Glass curtain wall is an architectural feature that consists of an exterior building envelope made predominantly of glass panels. It is designed to provide a transparent or translucent façade that allows natural light to enter the building while offering a sleek and modern aesthetic.
The glass panels used in a curtain wall system are typically framed with aluminum or steel supports, creating a lightweight and structurally sound assembly. These frames are strategically positioned and connected to the building's structural framework, providing support and stability to the glass panels.
Color Steel Panel Roof And Wall
Color steel panel roof and wall refer to a construction system that employs color-coated steel panels as the primary material for roofing and wall cladding applications. This system is commonly used in various types of buildings, including residential, commercial, and industrial structures.
Aluminium alloy roofing refers to a roofing system that utilizes roofing materials made from aluminium alloys. This type of roofing is widely used in residential, commercial, and industrial buildings due to its lightweight, durability, and corrosion resistance.
Aluminium curtain wall system refers to an architectural construction system that utilizes aluminium frames and panels to create an exterior building envelope. It is designed to provide a lightweight, durable, and aesthetically pleasing façade for buildings.
ACP panel wall refers to a construction system that utilizes Aluminum Composite Panels (ACP) as the primary material for exterior wall cladding. ACP panels consist of two thin aluminum sheets bonded to a core material, typically made of polyethylene or a fire-resistant mineral core.
Aluminium panel curtain walls are defined as thin, usually aluminum-framed walls that contain infills of glass, sheet metal, or thin stone. The curtain wall with aluminium composite panel cladding is attached to the building structure and does not carry the floor or roof loads of the building.
What is Stone Curtain Wall
It is composed of stone panels and supporting structures (beams, columns, steel structures, connectors, etc.), and is a building envelope structure that does not bear the load and function of the main structure. Good natural texture, high-grade appearance, good thermal insulation performance, easy installation, etc.
Advantages of Stone Curtain Wall
Beautiful atmosphere: Natural stone has a unique texture, colour and texture, which can give the building a noble and elegant appearance. Different kinds of stone such as granite, marble, etc. can be selected according to the needs of architectural design to achieve different decorative effects. Stone curtain wall can be integrated with a variety of architectural styles, whether it is modern minimalist style or classical European style, can show a unique charm.
Sturdy and durable: Natural stone has high strength and hardness, and can resist the erosion of various natural environments, such as wind, rain, sun, frost and so on. Stone curtain wall has a long service life, generally up to several decades or even hundreds of years, reducing the maintenance and replacement costs of the building in the course of use.
Good fire performance: Stone is a non-combustible material with good fire performance. In the event of fire, stone curtain wall can effectively prevent the spread of fire, providing valuable time for evacuation and fire rescue.
Thermal insulation: Some stone curtain wall systems can be combined with thermal insulation materials to improve the thermal insulation performance of buildings and reduce energy consumption. For example, the stone curtain wall and the main structure of the building set between the thermal insulation layer, can effectively reduce the transfer of indoor and outdoor heat.
Wet pasted stone curtain wall
The traditional wet pasting is the old process of adding reinforcement mesh to the wall, fixing the plate with copper wire, and pouring cement mortar into layers. This process has many disadvantages when applied to the exterior wall, not only because of calcium bicarbonate precipitation (whitening frost) and water stains after the cement mortar is pasted on the board, which make the wall stone color change, form color difference and pollute the wall; Moreover, due to temperature change and other reasons, it is easy to cause wall hollowing, cracking, and even falling off. Therefore, it is gradually eliminated.
Dry hanging stone curtain wall
There are many kinds of dry pendants, and each kind of pendant has its own installation method. The dry hanging method is directly related to the structure, installation, comprehensive cost, and beauty of the curtain wall. Since it was introduced from abroad in the mid-1980s, the dry hanging method of stone curtain walls has become increasingly innovative, evolving from pin type, butterfly type, etc. to back hanging and seam hanging.
Inverted stone curtain wall
Stainless steel T-shaped pendant shall be used for hanging upside down stone, and it is better to use a back bolt system pendant from the perspective of safety
The back bolt and long bolt shall be used for reliable mechanical fixation, and the back of the stone shall be pasted with protective cloth.
Selection of Stone Curtain Wall Materials
Stone slab
The stone curtain wall, as the outer enclosure structure, does not bear the load of the main structure, but it is located on the outer surface of the building. In addition to bearing its own weight, it also bears the impact of wind load, earthquake, and temperature changes. Therefore, the stone must be safe and reliable. The performance and quality requirements for stone materials include compressive strength, flexural strength, flexural strength, hardness, abrasion resistance, frost resistance, fire resistance, processability, etc.
The stone used for the stone curtain walls is naturally formed. The natural stone is mined from the mountain. Its important performance depends on the mineral composition and structure. However, each sample has a difference in the above series of properties tested by sampling, which is not as different as that of industrial products. Due to the different sampling surfaces, the measured properties will not be completely consistent. Based on the above situation, when the architect determines the type of stone, he must be careful in the use of stone slabs, and should do a good job in the following aspects:
1. Basic material property test: its compressive strength, flexural strength, flexural strength, hardness, abrasion resistance, frost resistance, fire resistance, processability, etc. must meet the specification and design requirements. At the same time, each batch of stone slabs used for the curtain wall shall be subject to a flexural strength test. Freezing and thawing tests are also required for areas where negative temperatures may occur. It can be used only when all performance indicators meet the design and specification requirements.
2. Control the processing accuracy of stone to avoid secondary cutting at the construction site. Affected by the installation process, the commonly used stone dry-hanging process requires drilling or grooving on the cross-section of the stone slab. Therefore, the thickness of the stone is limited by the installation process, and structural thickness must be guaranteed. Therefore, special attention should be paid to the thickness of the stone slab during the process of acceptance of the stone slab. The allowable deviation is+2mm, and no negative difference is allowed. It should be checked piece by piece.
3. Damage shall be avoided during mining, transportation, cutting, and installation. Once the formed stone plates collide, the damage, especially the internal injury, is difficult to be detected, but it will develop over time, and in serious cases, it will break, bringing potential safety hazards. The processing, transportation, and installation of stone materials shall be strictly controlled.
4. Protect the stone surface to ensure the dryness of the stone interior and that the natural property of the stone remains unchanged.
5. The area of a single stone shall not be too large, and the Technical Code for Metal and Stone Curtain Wall Engineering shall not exceed 1.5 square meters.
6. Stacking of stone.
Stack in the specified site according to the specifications of the plates;
It is strictly prohibited to mix with corrosive materials. Avoid contact with acid and alkali substances;
The product processing sequence number shall be marked, and attention shall be paid not to collision, pollution, etc. Use long permeable materials to pad 100mm at the bottom of the plate and ensure its stability.
Stone dry hanging adhesive
The load borne by the stone curtain wall panel is transferred to the pendant by the glue between the stone and the pendant and then transferred to the supporting structure by the pendant. Therefore, the dry hanging glue of the stone curtain wall must be structural glue. At the same time, the dry hanging glue must have good adhesion with the stone and the pendant (the material of the pendant can be stainless steel or aluminum alloy). The adhesive layer itself must have appropriate strength, good toughness, and elasticity.
On the basis of the correct selection of stone dry hanging adhesive, compatibility and adhesion tests of dry hanging adhesive shall also be conducted, and it can be used in the project only after passing the test. It is also very important to use dry hanging adhesive reasonably during construction, and the following points should be noted:
1. The stone hanging slot, the preparation and application of dry hanging glue, and the fixation of dry hanging parts shall be directly carried out in the processing workshop; The slotting of stone must be machined, and the slotting process control and processing inspection shall be strengthened to avoid damaging the stone.
2. The pasting surface shall be dry and dry (the humidity shall not be higher than 15%), free of dust, clean, rough, and oil stain.
3. The physical and mechanical properties of the dry hanging adhesive are directly related to the adhesive thickness (generally 1 mm~2 mm). The processing of dry hanging parts and dry hanging slots should be strict to ensure processing size and accuracy. The matching of dry hanging parts and dry hanging slots should be strict to ensure the thickness and depth of dry hanging adhesive.
4.As the strength of the stone dry hanging adhesive is related to the curing time and temperature, it is necessary to ensure that there is enough curing time and that it cannot be moved or loaded at the initial stage of curing.
Types of Stone Curtain Wall
Stick System Curtain Walls
Stick system curtain walls are one of the most common types of curtain wall systems used in architectural projects. In this system, the components are fabricated and installed piece by piece on-site. This allows for flexibility in design and ease of replacement if individual components need maintenance or repair. The installation process can be labour-intensive, but it allows for greater adaptability to the building's structure and requirements.
One of the key benefits of stick system curtain walls is the ability to customise the system to accommodate design nuances such as complex geometries or special requirements for wind loads and thermal performance. Architects and designers often prefer this system when working on unique or challenging projects that demand a high level of customisation.
Unitized Curtain Walls
Unitized curtain walls are a more modern approach to curtain wall systems, where the components are prefabricated off-site in modules or units. These units are then transported to the construction site and assembled onto the building's structure. This method reduces on-site construction time and labour costs, making it an efficient choice for large-scale projects.
Unitized curtain walls offer improved quality control as the units are fabricated in a controlled factory environment, reducing the risk of errors or inconsistencies in installation. The system also provides better thermal performance and weather protection due to tighter seals between the units, enhancing the building's overall energy efficiency.
Application Areas of Stone Curtain Wall
Commercial buildings: Curtain walls are commonly used in commercial buildings, such as offices, hotels, shopping malls, exhibition centers, etc. Curtain walls can create a modern and attractive appearance for the buildings, and enhance their brand image and competitiveness. Curtain walls can also provide a comfortable and pleasant indoor environment for the occupants, and improve their work efficiency and satisfaction.
Residential buildings: Curtain walls are also used in residential buildings, such as apartments, villas, dormitories, etc. Curtain walls can improve the living quality and comfort of the residents, and create a harmonious and cozy atmosphere. Curtain walls can also increase the natural lighting and ventilation of the buildings, and reduce the energy consumption and cost.
Public buildings: Curtain walls are widely used in public buildings, such as hospitals, schools, museums, libraries, stadiums, airports, etc. Curtain walls can enhance the public service and social function of the buildings, and reflect their cultural and artistic value. Curtain walls can also provide a safe and healthy indoor environment for the users, and meet their diverse and specific needs.
Industrial buildings: Curtain walls are also used in industrial buildings, such as factories, warehouses, laboratories, etc. Curtain walls can improve the production efficiency and quality of the buildings, and protect the equipment and materials from external damage. Curtain walls can also reduce the noise and pollution of the buildings, and ensure the safety and health of the workers.
Stone Curtain Wall to Maintenance
Cleaning is the first step in maintaining youStone Curtain Wall. Start by brushing off any loose dirt or debris with a soft-bristled brush. Be gentle to avoid scratching the stone surface. For more stubborn dirt, use a mild detergent mixed with water. Apply the solution with a sponge and scrub gently. Rinse thoroughly with clean water to remove any soap residue.
Avoid using harsh chemicals or abrasive cleaners, as they can damage the stone. Instead, opt for pH-neutral cleaners specifically designed for stone surfaces. Regular cleaning will help keep the stone looking fresh and prevent the build-up of grime and stains.
Protection is key to preventing damage to your stone wall. Applying a stone sealer can create a protective barrier that repels water, oil, and other contaminants. Choose a high-quality sealer that is appropriate for the type of stone you have. Follow the manufacturer's instructions for application, and reapply as needed.
In addition to sealing, consider using weatherproof covers or overhangs to protect outdoor stone from the elements. This can help prevent water damage, erosion, and colour fading caused by UV rays.
Despite your best efforts, minor damages may still occur. Small cracks and chips can be repaired using a stone repair kit, which typically includes epoxy resin and colour-matching materials. Clean the damaged area thoroughly before applying the repair compound. Follow the instructions carefully and allow the repair to cure completely.
For more significant damage, it may be necessary to replace the affected stone. This can be a complex process, so it's best to consult a professional if you're not confident in your ability to do it yourself. Regular inspections and prompt repairs can prevent minor issues from becoming major problems.
Using Harsh Chemicals: Strong cleaners can damage the stone's surface and cause discolouration. These chemicals can strip away the natural beauty of the stone and weaken its structure over time. Stick to gentle, pH-neutral cleaners that are specifically designed for stone surfaces to ensure longevity and preserve the aesthetic appeal.
Neglecting Regular Cleaning: Allowing dirt and grime to build up can lead to staining and other damage. Over time, this accumulation can penetrate the stone's porous surface, making it difficult to clean without causing harm. Make cleaning a regular part of your maintenance routine by wiping down the with a soft cloth and using appropriate cleaning agents. This will not only maintain its appearance but also prevent potential damage.
Skipping the Sealer: Failing to apply a stone sealer leaves your vulnerable to water damage and stains. Water infiltration can cause the stone to crack or develop mould and mildew, compromising its structural integrity. Seal your stone regularly, typically once or twice a year, to create a protective barrier that guards against moisture and stains. This extra layer of protection will help the stone withstand harsh weather conditions and everyday wear and tear.
