At present, the steel structure of space frame processing engineering in China is still in the development stage, and it does not account for a large proportion of the total output value of all engineering buildings.Space frame is widely used in stadium steel structure design, hangar steel structure, conference hall design. Xuzhou LFBJMB space frame Steel Structure Engineering Co., Ltd. learned that some of the city's landmark projects, overseas companies enjoy from the design concept to the overall design, most of the steel structure space frame companies in China are only manufacturing, production and processing.
In recent years, the frequent bidding of large and medium-sized engineering projects by some investors should have caused Chinese people to think and pay attention. In the practice of engineering projects in China, a batch of engineering buildings with novel designs have been built with high engineering budgets and high consumables. It violates the original intention of the steel structure to be environmentally friendly, lightweight, and environmentally friendly. Among them, the famous one should be the Beijing Bird’s Nest. From the panoramic view, it looks like the Beijing Bird’s Nest, “walking into nature”, “pure and pure”, and from the night view, it is crystal clear and full of phantoms. It has won the favor of many experts and leaders. After completion, does it look as charming as the 3D rendering on engineering drawings?

In fact, when fans enter the Beijing Bird's Nest to watch the game, what they see at a glance may not be the expected effect of the aerial viewing platform, but just some large inclined beams and steel columns. Some project engineers even clearly pointed out that the load of the Beijing Bird's Nest The irrationality of the structural management model has caused us to pour huge human resources, material resources and funds. According to the analysis of foreign representative engineering projects, it can be found that:

one. Foreign design projects are mostly focused on key projects in the capital and coastal cities of Beijing. They have sufficient funds and are not too stingy about economic benefits. However, the design projects of Chinese space frame manufacturers are mostly regional projects with fixed investment. Its rationalization remains a key element in program selection.

two. The structural management mode designed in foreign countries mostly adopts simply supported truss structures with large steel consumption in plan, while China adopts relatively excellent indoor space spherical space frames and reticulated shells. Therefore, the steel content of foreign designs is generally higher than 100kg/, and some It can reach many hundreds of kg/, while Chinese designs are generally less than 100kg/, and some can be as low as 20-30100kg/.

three. Foreign designs have strange shapes, but the load management mode and structure are traditional and complicated, which increases the net weight and consumables, and increases the workload. Everyone has seen the confidence of China's steel space frame processing companies to improve themselves and develop towards green, environmentally friendly, economical and practical steel structures. Even if the company is only working hard for the survival of its own famous brand, but then everyone can get an inspiration. If all companies want to responsibly develop the company's steel structure cultural creativity, then China's steel structure space frame processing It will definitely carry out the original intention of low-carbon engineering construction.

The space frame production and processing can be factory-like, using professionally designed automatic production lines, large-scale production, and exquisite manufacturing technology, which reduces the problem of manpower on-site construction and ensures product quality and production time. After the service life of the space frame frame is over, the material utilization rate is high, and it has the advantages of faster construction speed, low noise, and less environmental pollution of smoke and dust, which is unparalleled by other structures.

The key point is that the safety factor of the steel space frame structure is much higher than that of the concrete structure, and the use of composite wall materials as th

e enclosure structure has high flame retardancy, and the sound insulation and noise reduction effect is very good. Steel structure buildings can not only withstand earthquakes of magnitude 9, but also are not afraid of the invasion of pests such as white ants, which prolongs the service life of the house and greatly reduces maintenance costs.

As a green building and a green energy-saving building, the steel structure housing of the space frame has been widely used in the world by virtue of its advantages of good durability, flexible and flexible space, and environmental protection.

Steel structure space frame is a kind of structure of steel structure. High bending rigidity, good comprehensiveness, strong seismic performance, and high structural safety factor. It is light in weight, saves stainless steel plates, and has a small structural, which can make reasonable use of building space. Large adaptability, suitable for buildings with large, medium and small spans and various plan forms, such as hall roofing, prefab hangar , stadium steel structure design, galvanized steel warehouse, glass dome building, gas station canopy, and convenient sampling, materials There are various forms of cross-section to meet the humanized requirements of customers. Large-span engineering buildings can be completed with small-sized material cross-sections. The material specifications and models are uniform, and the shoddy situation is gone. The construction progress is improved, and it can be disassembled and reused many times, which improves the utilization rate of materials and saves energy.

The development and application of steel structure space frames have promoted the development of space frames, promoted the construction of economic development, improved the daily life of the people, developed the market, and enhanced the color of art.

It consists of the intersection of two plane trusses parallel to the direction of the space frames building boundary. The intersection angle of the trusses in each direction is 90 degrees, that is, the upper and lower chords are placed positively

The lengths of the upper and lower chords are equal, and the upper and lower chords and The lengths of the upper and lower chords are equal, and the upper and lower chords and

It is greatly affected by the plane size and support conditions. The peripheral support is close to a square plane, the force is uniform, and the internal force of the rod is not very different. With the increase of the side length ratio, the one-way force characteristic is obvious

There are few types of rods, which can be assembled into a plane truss first, and then assembled together, which is more conducive to construction

link textLarge-span structures can be divided into two categories: plane structure system and spatial structure system according to the difference in geometric shape, combination method, structural material, and stress characteristics.

Plane structure system: beam structure (planar truss, space truss), plane rigid frame and arch structure.

Spatial structure system: flat space frame architecture, reticulated shell structure, most of the suspension cable structure, cable-stayed structure, tension structure, etc.

The steel structure project is located at Balisong 3rd Road, Longhua District, Shenzhen. As one of the iconic composite steel structure buildings in Longhua District, the designer hopes to create a natural & open vibrant neighborhood for users in a high-density city through the language of architecture, and welcome the citizens with the attitude of a "city image living room".

Based on the design concept of "Green Valley-Cloud Street", the apartment part is arranged on the north side of the base, adjacent to Balisong Park, enjoying a high-quality natural landscape; the office part is arranged on the south side of the base, echoing the business district with tall buildings in the future. The podium opens along the northeast-southwest direction to form an open square. The two high towers are arranged diagonally to create a "valley" visual experience for the podium; the open space "Green Valley Cloud Street" is built into the enclosed space of the double towers, and it is an enlarged Block node space, creating a regional commercial core. The design of the retreat podium extends the greenery of the park to the inside of the block and connects with the green space outside the base to form a landscape corridor.

The overall shape of the building is simple and elegant. The metal and glass skins are interlaced with green plants on each layer. From the air, the towers at both ends resemble two mountain peaks. The building is overly natural and integrated with the surrounding environment.

More and more commercial centers will adopt the dome glass roof building design, and the steel structure is very fashionable due to the large-span design and the ability to make various shapes, especially when a large area of glass is laid on the roof, the interior of the mall is very fashionable. The silent style of concrete is completely broken by this stylish and concise lighting roof, which highlights the fashionable temperament of the mall.
At the same time, with the steel structure, the mall can hang a large area of advertising banners under the glass dome builidng, or install different ornaments at will to add slogans of different festivals, and the commercial value is unlimited. This is why more and more businesses will break into more money to make a glass dome roof.
