What shapes does the membrane structure shed have

In recent years, it can be said that membrane structure sheds have been widely used, from sports, commerce, industry and other fields to landscape, urban sketches, transportation facilities and other fields. No matter in which field, its appearance is not only fashionable, high-end atmosphere, but also has excellent performance.Now, many people may find that in some schools and companies, facilities such as parking sheds are used, which effectively facilitates the parking and use of bicycles and cars, and as long as they understand the parking sheds, they can watch. So far, there are more types of membrane structure sheds. The emergence of this new type of facilities has brought many conveniences to people's lives, so such sheds can play a specific role.Nowadays, there are mainly two types of membrane structure sheds, one is reverse tension structure sheds, and the other is the same direction bending tension structure sheds. The sheds of these two structures have a certain degree in the process of use. Therefore, the installation requirements are also different. Customers can choose according to their own needs. Because there are more types of membrane structure sheds, users who need them will make choices according to different situations. Now let's introduce the classification of membrane structure sheds.The classification of membrane structure shed modeling can generally be divided into three categories:1. Flat roof membrane structure shed: hard edge at the rear, raised at the front, and fixed by cables. There is a gap between the front and back for drainage. In addition, there is a double pick type, which can also be classified as flat top type;2. Hat top membrane structure shed: the main appearance is the hat shaped roof with an arch in the middle. The cable is pulled out of the middle hat top and fixed on the column. The car shed with hat top membrane structure is composed of many roofs connected together to form a large car shed.3. Tension structure shed: This is a typical application of tension membrane in shed. There is no fixed form. It will expand many shapes as required. In addition to its practicality, it is also more beautiful.

How to deal with color difference in membrane structure shed

If the membrane surface of the membrane structure shed has various colors, it will not look beautiful, and will affect its overall use from the side. How should we deal with this phenomenon?1. It should be determined whether the film materials with different color differences match the brand type. This requires suppliers to provide comprehensive company certification materials that integrate formal design, production, installation and construction.2. Secondly, send the sample membrane materials to a third party for testing to check whether the membrane materials used in the membrane structure shed are qualified.3. In the case of both the above two points, the color difference film can usually change back to the matching color after being exposed to the sun for a period of time.Compared with traditional projects, the construction period of membrane structure shed is greatly shortened, but this does not mean that the installation procedures will be greatly reduced. During the construction process, it is necessary to pay attention to some matters and make preparations in advance.1. When the general membrane structure shed is under construction, construction warning signs should be made. Obvious warning signs and guardrails shall be set up in dangerous areas at the construction site.2. For each construction site, it must ensure that the roads in the workplace are unobstructed, and the dangerous parts must be marked with obvious signs.3. High altitude operation is essential in the construction of membrane structure shed, so the ladder used for climbing must be firm, and the height between the ladder and the ground is usually 60 degrees to 70 degrees.4. Due to the high risk of installing the membrane structure shed, the steel wire rope used for hoisting must be carefully checked in advance.5. When using the crane, it is strictly forbidden to contact the high-voltage overhead line with the boom, steel wire rope and heavy objects, and keep a certain safe distance from the overhead line. Take protective measures for high-voltage power lines when necessary.6. In order to prevent arc radiation, welders must wear protective masks (with filters inside) when building membrane structure sheds. When welding in public places, movable light barriers must be installed.7. The welding site should have good ventilation, exhaust devices and good lighting.8. When building the membrane structure shed, a special person must be responsible for evenly guiding and lifting materials, and it is strictly forbidden to stand under heavy objects. Materials must be fixed to prevent accidents.

Four points for attention of membrane structure shed

Membrane structure is used more and more widely, no matter in shopping malls, transportation facilities, gardens and so on. Whether in shopping malls or residential areas, parking sheds are essential. In order to ensure everyone's life safety, many accidents will be caused if the construction of the parking shed is unstable. Therefore, the following four points should be paid attention to when making the parking shed:First, the overall frame of the membrane structure parking shed adopts square steel welded keel frame. The whole frame is treated with rust prevention, brushed with three times of rust prevention primer, and the surface is sprayed with white high-grade automotive paint. The main column of the parking shed adopts 150 × 150 galvanized square pipe is used as the support column of the parking shed, and the overall structure of the parking shed is firm, with high seismic and wind resistance coefficient and corrosion resistance;Second, the sealing plate on the top of the membrane structure parking shed is sealed with brown (color can be selected) sunlight plate, which is riveted and fixed with the overall skeleton of the shed with battens, which is acid and alkali resistant and has sufficient strength to protect the vehicles in the shed;Third, the membrane structure is used inside the parking shed Φ 38 galvanized round pipe is welded with the shed frame to strengthen the strength of the shed top, which can make the shed feel spacious and bright, and the parking of vehicles is easy and convenient, which fully meets the requirements and specifications for the production of the shed;Fourth, the column foot of the membrane structure parking shed adopts 10mm thick steel plate to be firmly welded with the embedded parts. When installing the parking shed, the embedded parts are poured with concrete and connected with the vertical with bolts. The wind resistance coefficient is high, which increases the overall firmness of the parking shed and can resist the attack of typhoons above grade 12.

What should be paid attention to when cutting joints in the installation of membrane structure shed?

Because the membrane structure shed is a kind of spatial structure form, which is made of a variety of high-strength membrane materials and reinforcing members (steel frame, steel column or steel cable) to produce a certain amount of pretension stress inside in a certain way to form a certain spatial shape. As a covering structure, it can bear a certain external load. Therefore, this characteristic of membrane structure shed should be fully considered when cutting. So, what should we pay attention to when cutting seams on the surface of the membrane structure shed?

Development trend of membrane structure in China

With the construction of some large gymnasiums and waiting halls, as well as the holding of international events such as the 2010 Foshan Luocun Cultural Square 1800 Shanghai WorldExpo and the Guangzhou Asian Games, opportunities and challenges have been brought to the development of membrane structures in China. Especially in terms of membrane materials, China started late and its technical level is low. Most of the membrane materials still rely on imports. PTFE, PVC, surface modified PVC, ETFE and other membrane materials are the mainstream of the market and are widely used.China has the independent intellectual property rights of PTFE membrane materials, and the performance basically meets the requirements of similar foreign products. Many companies, scientific research institutions and universities are carrying out research on PVC surface coating materials, such as PVDF, nano TiO2 surface coating agent, etc., which have achieved initial results. In addition, research on surface antifouling and self-cleaning treatment, such as bionic lotus leaf construction of micro rough surface, has also begun. While introducing advanced production equipment and technology, it is of great significance to step up digestion, absorption, improvement and innovation, and develop membrane surface treatment technology suitable for China's market demand as soon as possible, so as to improve the grade and market competitiveness of China's industrial textiles.

Problems needing attention in membrane structure engineering construction

① Before unfolding the membrane, lay temporary cloth on the platform to protect the membrane from damage and cleaning, and unfold the membrane in strict accordance with the determined sequence. Before opening the package, check the mark on the package, confirm the installation position, and unfold it according to the direction of the mark, so as to avoid the movement of the unfolded membrane in the field as far as possible. Wear soft soled shoes when walking on the unfolded membrane surface, and do not wear hard objects to prevent the membrane body from being scratched.

How to distinguish the good and bad of membrane structure shed

Nowadays, in daily life, we often see various shapes of membrane structure sheds, so how to distinguish between its good and bad?1. Daylighting. The sunlight shining on the roof is transmitted indoors in the form of diffuse light. From the inside, the roof becomes a continuous bright surface, and its intensity changes due to the relative position of the roof and the sun.The daylighting coefficient (i.e. the ratio of indoor and outdoor natural light and sunshine degree) of the indoor air in the tension membrane structure shed can generally be as high as 10%; In the traditional construction, the light can only enter the room from the limited daylighting window, and its daylighting coefficient is less than 3%. Even on overcast days, the lighting level in the membrane structure room can meet the basic requirements of most activities.2. Reflective. Because the transmitted light and reflected light entering the membrane structure shed are diffuse light, glare is unlikely to appear. However, we should consider the arrangement of the glass lighting area and shading to avoid the glare caused by its direct light.3. Color. Film structure shed indoors, people will have a good color perception of white or off white film materials, because these two colors show the characteristics of linear spectral transmission to visible light. The transmission degree increases with the increase of the wavelength of the transmitted light, which makes the transmitted light slightly warmer than the incident light. Transmission spectrum, fiber and its characteristics, coating thickness, etc.In addition, it is also important to choose a suitable membrane structure design company.1. Formal or not: when we choose a membrane structure garage design company, the first thing we need to consider is the other party's qualification. The other party must be at least a formal and legal company to design quality. To check this, you can check its business license or its relevant records on the website of the Administration for Industry and commerce. Of course, the condition is that you can go to the other party's company for on-site investigation.2. Employee quality: this employee quality mainly refers to the strength of the designer. Whether the designer of the other company has relevant professional qualification certificate and what level it is should be made clear. After all, what we do in design is to implement it on people. The concept, level and creativity of designers are very important, which also has a great impact on our architectural results.3. Company strength: the level of designers is only one aspect, and the strength of the whole company is the important standard. But strength is illusory after all, and it is difficult to say clearly, and we cannot blindly listen to each other's one-sided words. Then what shall I do? Easy to handle! Two keys: cases and word of mouth. A powerful enterprise must have many successful cases and good reputation in the industry. When we choose a design company, we should focus on checking the other party's information. If it is two companies with similar strength, we should choose the successful case that is close to our situation.4. After sales service: design is not a one-off deal, and the design of membrane structure shed is far more complex than we thought. So when we are looking for a design company, we must comprehensively consider its after-sales service. Once there are any problems in the design draft, we have to send it back for them to modify. If there are problems in the construction, we also need the designer to participate in solving them. These are very practical problems.
