America US Standard Certified Customized Membrane Structural Car Parking Carport

Membrane is a new type of building structure developed in the middle of the 20th century. It is made of a variety of high-strength film materials (PVC or Teflon) and reinforcing members (steel frame, steel column or steel cable) through a certain method to make the interior A certain pre-tensioning stress is generated to form a certain spatial shape as a covering structure and a spatial structure form that can bear a certain external load. Membrane structure can be divided into two categories: inflatable membrane structure and tensioned membrane structure. The inflatable membrane structure is continuously inflated inside the room, so that a certain pressure difference between indoor and outdoor (usually between 10 mm and 30 mm water column) is generated. The pressure difference between indoor and outdoor makes the roof membrane cloth subject to a certain upward buoyancy, thereby achieving greater span. The tensile structure is supported by columns and steel frames or formed by steel cables, and its shape is very beautiful and flexible.
 
Membrane structure carport is a structural system composed of architectural fabric, that is, membrane material as the main body of tension, and supporting members or cables. It has a novel and unique architectural shape and good stress characteristics-becoming a large-span spatial structure One of the main forms. Membrane materials refer to different surface coatings such as polyester fiber base fabric or PVDF, PVF, PTFE, etc., together with high-quality PVC, which has a stable shape and can withstand a certain load. Its life span varies with different surface coatings, and can generally reach 10-20 years.
 
Specifications:

 
Type:
The first type is reverse tension membrane structure; reverse bending shape, or double bending saddle shape with tension and stability. The tension and stability come from the mechanical prestress of the membrane plane and its linear boundary.
The second type is the same direction bending tension membrane structure; the same direction bending shape, or the double bending spherical shape with tension and stability. Tension and stability are produced by air or water pressure acting perpendicularly to the membrane surface. This type of structure includes air-bearing structures and inflatable structures.
 
Feature:
1. Durable: Due to the emergence of high-strength membrane materials, coupled with the application of tension technology, the membrane structure carport's ability to withstand wind and rain is incomparable to ordinary awnings. Some carports use permanent membrane materials, which can be used for 30 to 40 years. Especially in severe stormy weather, the membrane structure building stands still and undamaged.
2. Artistic quality: In addition to the practical, durable, wind- and rain-shielding functions that are incomparable to ordinary awnings, the membrane structure awning is a sculpture and a work of art, giving people a beautiful visual enjoyment. Its soft beauty, its curve, its strength and softness, its rich shape, its whiteness and flawlessness, make people's eyes bright and long aftertaste.
3. Economical efficiency: Studies have shown that the performance loss of vehicles parked in the open for a long time is twice as fast as that of vehicles parked in the carport. The membrane structure canopy can really care for your car and slow down the aging speed of your car. From an economic point of view, not much investment can greatly extend the life of your ride.
4. Light transmittance: good light transmittance (20% light transmittance). Exposure to the sun will not produce yellowing, fogging, and poor light transmission.
5. Weather resistance: There is a UV-proof co-extruded layer on the surface to prevent the resin from fatigue and yellowing caused by solar ultraviolet rays. The surface co-extruded layer chemically absorbs ultraviolet light and converts it into visible light. It has a good stabilizing effect on plant photosynthesis (it is very suitable for protecting all kinds of cars, valuable artworks and exhibits from UV damage).
6. Impact resistance: The impact strength of architectural membranes is 250-300 times that of ordinary glass, 20-30 times that of acrylic sheets, and twice that of tempered glass. There is almost no risk of breaking, and there is "no glass breaking". And the reputation of "Sound Steel".
7. Flame retardancy: According to the national GB8624-97 test, it belongs to the flame retardant B1 level, no fire drop, no poisonous gas.
8. Temperature resistance: in the temperature range of -40 degrees to 120 degrees Celsius, it will not cause quality deterioration such as deformation.
9. Portability: Light weight, absolutely guarantee the safety of people and things under the shed.
10. Sound insulation: good sound insulation effect.
 
Classification:
The architectural structure of the membrane structure is colorful and ever-changing. According to the support method, it is divided into an inflatable membrane structure, a tensile membrane structure and a skeleton support membrane structure.
1. Skeleton membrane structure
The roof skeleton made of steel structure or integrated material is stretched above the membrane structure, and the lower support structure has high stability. Due to the simple roof shape, the opening is not easy to be restricted, and it has high economic benefits. It is widely applicable For any large and small space.
2. Tensile membrane structure
It is composed of membrane material, steel cable and pillar, and uses steel cable and pillar to introduce tension into the membrane material to achieve a stable form. In addition to practicing creative, innovative and beautiful shapes, it is also the most structural form that can demonstrate the spirit of membrane structure. Large-span spaces also mostly use steel cables and compressed materials to form a steel wire mesh to support the upper membrane. Due to high construction accuracy requirements, strong structural performance, and rich expressive power, the construction cost is slightly higher than the skeleton membrane structure.
3. Inflatable membrane structure
The inflatable membrane structure is to fix the membrane material around the roof structure. After the indoor air pressure is raised to a certain pressure by the air supply system, the pressure difference between the inside and outside of the roof is generated to resist the external force. Because the air pressure is used for support, and the steel cable is used as an auxiliary material , Without any beam and column support, it can get more space, quick construction and high economic benefit, but it needs to maintain the 24-hour blower operation, which is higher in the cost of continuous operation and machine maintenance costs.
