How to install the air film? What to look out for?

The installation process of air dome building is relatively complex and requires a professional team and equipment. The following are the general steps and things to look out for in the installation of air dome construction:

Installation Steps: Design and Planning: Before starting installation, detailed design and planning is required, including determining the size, shape, structure, and layout of the building. This requires collaboration with professional architectural designers and engineers.

Foundation Preparation: After choosing a building location, foundation preparation work is required. This may include the leveling of the ground, the setting of drainage systems, and the construction of the necessary foundation support structures.

Membrane prefabrication: Membrane for air film construction is usually prefabricated in a factory and then transported to the construction site for installation. The fabrication of the film typically involves welding the diaphragm to a predetermined size and shape to ensure quality and accuracy.

Membrane installation: On the construction site, the membrane will be installed on the supporting structure of the building. This typically involves lifting and tensioning the membrane to ensure that it is flat and fits snugly into the support structure.

Support Structure Installation: The support structure of an air membrane building usually consists of a steel or aluminum frame, and they must be installed correctly to support the membrane and ensure the stability and structural integrity of the building.

M&E equipment installation: This includes the installation of M&E equipment such as ventilation, heating, refrigeration, lighting, fire protection systems, etc., to ensure comfort and safety inside the building.

Interior decoration: Once the building's shell and M&E equipment are installed, interior decoration can be carried out, including floors, walls, seating, etc.

Testing and acceptance: After the installation is completed, the necessary testing and acceptance are carried out to ensure the normal operation of the building's functions.

Installation Notes:

Professional team: The installation of air film buildings requires a professional team, including architects, engineers, construction personnel, etc. Make sure to hire an experienced professional.

Safety measures: Strict safety standards are followed during the installation process to ensure the safety of workers. This includes proper use of lifting equipment, wearing safety gear, etc.

Maintenance Schedule: After the installation is complete, a regular maintenance schedule is in place to ensure the long-term performance and safety of the air dome building.

In conclusion, the installation of air dome buildings is a complex process that requires careful planning and execution to ensure the quality and reliability of the building. It's best to work with an experienced professional to make sure everything runs smoothly.

1. Lay the main membrane in order.

2. Personnel are grouped, each branch is assembled and connected, and special connectors are used for connection.

3. The group personnel install the soft connection of the airlock door and the emergency door according to the group, and use special tools and connectors; Connect soft connections in place by point.

4. The group personnel installs the anchoring system according to the group, and installs and uses special anchors and measuring tools.

5. After the installation of the main membrane, the overall inflation is carried out after checking that it is correct. Safety checks and adjustments are carried out during the project.

6. After the overall air film building is completely saturated, relevant data monitoring and calculation are carried out and compared. Conduct data review and record relevant data if necessary.

7. Adjust the overall membrane building, confirm that there is no displacement and error for the conveying, installation and adjustment of insulation materials.

8. After the overall installation is completed, the final inspection, monitoring and load test will be carried out, and finally the acceptance and handover will be carried out.

9. Start the mechanical unit and inflate it.

Before the installation of the air film, civil construction needs to be carried out, and the embedded parts of the concrete foundation and anchoring process are done for the air dome. Civil construction is one of the core projects of the air film construction site, and this link requires the construction unit to prepare a special construction plan.

After the completion of the civil engineering work of the air film, before the formal installation of the air film, the construction unit should check the product certificate, design documents and pre-assembly records of the membrane to ensure that the preparation work is correct.

During on-site installation, the membrane unit needs to be connected, and the quality of the connection directly affects the safety of the overall membrane structure. Therefore, it is necessary to reasonably design the connection form and correctly select the connection method to ensure that the connection design is safe, reliable and convenient for construction.

The membrane is generally composed of the substrate and the polymer of the membrane, that is, the substrate layer and the polymer coating are bonded together through a specific processing technology according to the required thickness and width, and there is a certain technical content

The precautions for the gas film coal shed are: 1. Check the factory certificate and quality assurance of the membrane body before installing the gas film coal shed, check and proofread the demand of the supporting structure and embedded components, spread the device and proofreading of the connecting parts of the membrane body and the membrane body, form the membrane surface according to the design requirements, and apply pretension according to the design requirements, fix the membrane surface and the supporting structure, inspect the connectors and connecting nodes, and detect and record the completed gas film coal shed.

2. Before the construction of the gas film coal shed, the factory statement, product warranty certificate, testing statement, variety, specification, color and quantity of the membrane body and spare parts should be inspected.

3. Pay attention to ventilation design The focus should be on solving the problem of ventilation, and reasonably setting the position of the air inlet and air outlet, which can effectively improve the ventilation situation of the air in the coal shed and achieve the purpose of zero dust emission.

Fourth, the installation of monitoring system in the coal shed set up explosion-proof spontaneous combustion monitoring and early warning system, when the dust concentration exceeds the standard, will send out an early warning signal, speed up the air flow in the coal shed to discharge excess dust, and there is a spray system can well reduce the dust concentration, so as to ensure the safety of the coal shed and the working environment.

In short, the above are some matters to be paid attention to in the air film coal shed, as long as it can be operated safely according to the above precautions.

The advantages of the gas film coal shed and its precautions!

1.Cost saving: no beams and columns, light weight, reduce civil engineering requirements and costs, save 25-60% of the cost, and the construction period is as short as 2-4 months.

2.Explosion prevention and fire protection: perfect gas, dust monitoring, emission system and a complete set of fire protection system.

3.Structural safety: 300 meters of super large span, can withstand 16 typhoons, more than 8**, nearly 1 meter thick snow load.

4.Intelligent control: no need for personnel to be on duty, equipped with a wireless control system, to achieve online remote control.

5.Environmental protection technology: professional dust removal and dust reduction measures to ensure that the exhaust is clean, environmentally friendly and pollution-free.

2. Precautions for gas film coal shed:

1.Dust**: After the coal yard is fully enclosed, it becomes a confined space, and the ventilation in the warehouse is poor, and once the dust generated during the operation forms a dust cloud, it is easy to cause dust when it encounters open flames or electrostatic ignition.

Countermeasures: perfect gas and dust monitoring, emission system and a complete set of fire protection system.

2.Occupational health and safety of workers: Because the fully enclosed coal bunker is a confined space, the dust concentration in the bunker is large, and the operators work in the bunker for a long time, which is very easy to get pneumoconiosis.

At the same time, the high temperature in summer, the temperature in the warehouse is as high as more than 50 degrees, and the operation is easy to get heat sickness, and there are major occupational health and safety risks. Countermeasures: Do a good job of ventilation design to ensure excellent ventilation conditions.

(1) The air tightness is destroyed.

The inflatable membrane structure building is supported by air, and the requirements for tightness are relatively high, and whether there is air leakage is the most important inspection element. Therefore, it is necessary to regularly inspect the tightness, strength and stiffness of each connection point of the inflatable membrane to check whether there is a risk of air leakage in the membrane structure building. At the same time, it is also necessary to check whether the appearance of the inflatable film is damaged, and whether the anti-corrosion performance of metal components such as anchor bolts is damaged.

2) The membrane is wrinkled or damaged.

The air film film is a kind of material with bending resistance and compressive stiffness that tends to be zero, and the film will not wrinkle when the shape finding analysis and load analysis are carried out in the design. Generally, for the anisotropic film material, when the principal strain in one direction is negative, the membrane element will appear in a unidirectional pleated state or a fully pleated state.

Because the air membrane structure building is a flexible building, it will be displaced due to oscillation when encountering strong winds, and the load acting on the structure will be redistributed through displacement. Therefore, the main body of the air film needs to maintain a proper safety distance from indoor and outdoor large-scale equipment and buildings to prevent the destruction of the membrane. The air film is afraid of sharp objects cutting, so all equipment and objects with sharp edges inside the air film building should be protected and isolated with mats to avoid contact and scratching the main body of the membrane structure.

3) The difference in air pressure is common.

For inflatable membrane structures, keeping the inflatable pressure within the design range is the key to maintaining the normal operation of the inflatable membrane building. If the difference between indoor and outdoor air pressure in the air membrane building is abnormal, it will affect the stability of the inflatable membrane structure and make it insufficient to resist the damage caused by strong winds and heavy snow.

The inflation pressure is closely related to the anchorage state of the foundation, the fan equipment, the control system, the backup power supply and the inflatable membrane structure itself, so it is necessary to ensure that these equipment are always in normal operation during daily use and maintenance.

4) Chromatic aberration. In the production process of the film, various corresponding coatings need to be applied to the substrate of polyester fiber fabric or glass fiber fabric to improve the durability, water resistance, self-cleaning and UV resistance of the film. However, there are often certain differences in the color of the membranes produced in different batches, and if the membranes with obvious differences in color and luster are placed in the same project, the aesthetics of the air membrane building will inevitably be affected.

The fire rating of the air film film is B1, and the applicable temperature environment is -40 to +70, so when setting up lights and heating equipment, pay attention not to get too close to the film material, so as not to burn the film material, leak air pressure, and damage the structure.

How to turn off the ECCN.

Just press the button.

It's almost a long time before it can't be torn clean. Regardless of whether you can tear it off or not, there is usually residue on it. Unless it didn't take long to put it on. Tearing off the film is more laborious than sticking the film, and it generally takes a morning to change a whole car of film for two people.

After the membrane is torn off, the residue on it is generally removed with dish soap water and a blade, and you can also use a recurring steel wool ball to add dish soap water, but it must be a new steel wool ball. Don't use steel wool balls that have been brushed over the pan, there is grease on them, which will stick to the glass and will be more difficult to clean.

Then it should be noted that now the rear windshield glass is generally equipped with defogging and **, if you directly use a blade or steel wool ball to clean, it will destroy the above plus **, and the rear windshield glass will lose its defogging function. There are also some side rear triangle glass with radio antennas, which also need attention.

To clean the glass with defogging and **, we can use hot water and dish soap, use a rough rag or a rag to clean the car interior, and slowly clean the wild forest. Of course, if you paste a little bit of the film, there will definitely be a film that cannot be torn clean, I can use a blade to tear it little by little, be careful not to scratch it. Of course, if you don't need to defog and add **, use a blade or steel closed song brother mu to clean it directly.

The air film written in the nucleic acid report refers to the air film version of the fire eye laboratory. The "Fire Eye" laboratory is a large-scale nucleic acid detection platform that can provide integrated pathogen detection solutions.

The appearance is a white arched air dome cabin, and the cabin adopts a modular layout, and the equipment is directly assembled after entering the site, which is much faster than the construction method of traditional technology. The volume of each air film chamber is more than 70 square meters, but the air film is only about 4 square meters after being stored, and it only takes about 50 minutes to fill the air film cabin with gas. The main role is to quickly and effectively deal with the current epidemic situation and quickly improve the nucleic acid testing capacity.

The "Fire Eye" laboratory has the advantages of automation and high throughput, with a daily nucleic acid testing capacity of tens of thousands, which will effectively alleviate the urgent need for nucleic acid testing.

The capsule was jointly designed by BGI, Tongji University and Itopia during the pandemic. The interior adopts a one-way barricade and vertical connection window layout, which can prevent cross-infection as much as possible. There is a one-way connecting window between the air film chambers, and the staff on one side can open the window and take it away after placing the large sample in the window.

Each air capsule is equipped with auxiliary conversion spaces such as airlock conversion, medical waste outlet, and changing room.

Every 3 air film chambers in the gas film version of the fire eye laboratory are a group, which are responsible for the three links of sample preparation, nucleic acid extraction, and nucleic acid detection, so as to form a complete laboratory. The same group of air capsules are connected to each other through the transfer window to transfer samples. These air film chambers are negative pressure, the incoming air will be filtered through the fresh air system, and the internal air will also be harmless through the high-efficiency filter before it can be discharged from the cabin.

The "Fire Eye" laboratory is also equipped with "black technology" - automatic nucleic acid detector, which has greatly improved the level and efficiency of nucleic acid testing. The automated nucleic acid detector can automatically complete a series of operations such as opening the kit, balancing the reagent, scanning the code and entering the information, reducing the demand for the number of personnel, meeting the requirements of increasing the detection throughput, and improving the accuracy of the test.
