LF space frame

In the early 1990s, Space frame structure just started to rise in China. Because of its technical content and accessories, it is synonymous with high-end roof structures. There are only some government public facilities projects, important complexes, and national sports centers  c an afford the  space frame structure. However, in recent years, especially at the beginning of this century, with the development of industrial automation and the emergence of a large number of grid personnel, space frame structure has gradually stepped off the high-priced altar and has been used in ordinary buildings. From the conference hall to the industrial workshop with a span of hundreds of meters, you can see the grid structure. In the future, this beautiful urban landscape will be extended to a wider area. LF is a professional manufacturer and engineering company for space frame and steel structure projects.Do you have a construction project we can help with? We are always ready to he...

The shape of the sports swimming pool is quite unique. As you can see from the picture, it looks like a butterfly's wings. However, it is linked to a swimming pool, which feels like a huge "bikini". The maximum span of the long axis of the swimming pool roof is 164 meters, and the maximum span of the short axis is 129.6 meters . The roof of the Hangzhou Olympic Sports Center Swimming Pool covering the three units of the lower concrete structure is a complete steel mesh shell structure, which naturally extends to an 8m platform, and the roof surface is a free   form surface. The roof of the swimming pool and the gymnasium area adopts a double-layer reticulated shell structure with variable thickness and oblique cross. The diamond-shaped grid of the reticulated shell has a side length of about 5m and a diagonal length of about 6.3mx9.2m. At the site of the swimming pool roof steel structure lifting project, a total of 12 lifting points and 12 sets of lifting frame...

The spatial  structure is particularly favored by large-scale stadium buildings because of its advantages of reasonable stress, beautiful shape, complex free three-dimensional space and minimum internal support mutual interference. The integrated design of the Shenzhen Bay Sports Center places the stadium, gymnasium and swimming pool under a white giant grid-like steel structure roof. The soft-line roof is like an incubator for sports athletes who break the cocoon and rush to the world. The novelty and unique shape are similar to the design method of "Bird's Nest". The unique structure of "One Field and Two Pavilions" makes the construction of "Spring Cocoon" more difficult than that of Bird's Nest . The steel structure of the Shenzhen Bay Sports Center is a large-span complex space structure. The steel structure roof is composed of a single-layer reticulated shell (stadium, large tree square and other public areas), a double-layer curved ...

Railway Station Roof Structural On May 16, 2020, the Beijing Section Shunyi West Railway Station completed the construction of the roof structure , and started  the construction of the metal roof  panel . The roof structure ,   adopting  bolted ball space structure , has an  area of about 3000 square meters. The design concept of Shunyi West Railway Station is "the eye of the airport". The Shunyi West Railway Station is designed as a "big-eyed" shape, which is a "super-elevated station building" with a scale of 2 sets of 4 lines, and 2 side-mounted platforms .

s patial structure YasViceroy Hotel is located in Abu Dhabi, United Arab Emirates. Half of the hotel is built on land, and the other half is on the water. The seemingly separated halves are blended together by the structure of the reticulated shell covering the outer layer. The whole building is not only elegant and dreamy under the night, but also can leave a grand atmosphere in the daytime. The hotel  ’ s reticulated   s patial  structure  is enough to amaze you, which is definitely a great engineering initiative. The 219-meter-wide giant s patial  structure and 5,096 diamond-shaped glass plates are perfectly inlaid, like a mysterious "veil" draped over the two hotel buildings. The two buildings are connected by a bridge that spans the race track and is magnificent. The hotel and the surrounding Abu Dhabi race track, the sea and the desert landscape complement each other, and its brilliant colors are a visual "gluttonous feast". At the same time, th...

dome space frame In the construction of long span dome  structure , the geometric characteristics of the spherical dome are fully utilized.   The lower outer edge is made of small units prefabricated on the ground and assembled in the air, The center ring part, which is higher from the ground, adopts the whole lifting method . finally in the air to the outer edge and the center of the ring group welding into a whole, to minimize the amount of scaffolding consumption and ensure the quality of the project and safe production.   This kind of installation method, reflected the advantage of whole hoisting already, overcame the inadequacy of bulk method again. C haracteristics 1. According to the structure characteristics of dome space structure  and its substructure, the grid is divided into several ring belts. The construction technology of combining the outer ring of small units with the outer ring of ground prefabrication and the central ring of ground prefa...

Since the coal storage yard is closed in a closed space, there are many problems such as dust explosion in the warehouse, spontaneous combustion of coal and occupational health and safety risks of workers.   Therefore, in order to ensure the normal operation of the coal storage yard, it is necessary to plan and design a ventilation scheme with good ventilation effect to ensure the closed coal bunker.   A good ventilation scheme can not only eliminate indoor dust and harmful gas pollution, provide a healthy and harmless air distribution condition in the work area, but also eliminate indoor waste heat and reduce the risk of fire and other safety accidents. Is fully enclosed coal mostly adopt the lower shutter + top ventilation skylight way of natural ventilation, because of the great closed coal bunker capacity, coupled with the roof material is made of color steel plate closed, air heat capacity is 3.14 tim es that of iron under the sunshine of ambient air temperature 3...

Guangzhou Opera House The theater adopts the integrated structure of roof and wall to present the irregular folding surface combination, which is named as the structural system of "three-synclinal intersecting grid combined folding plate type single-layer reticulated shell".   The outside walls are shaped like triangular panels, steel structure layout, stone partition and glass shards all follow this concept."Double gravel" adopts the structure of integrated roof and curtain wall. The maximum length of the overall shell is about 120 meters and the height is 43 meters. The biggest characteristic of this building is that it adopts the completely asymmetric non-geometric structure, and no node is the same from inside to outside. The steel structure is three-sided oblique folded plate type reticulated shell, which has 64 faces and 47 transfers. Each steel piece is cast in sections and transported to the site for stitching, with complex modeling.   Each node shoul...

glass dome structure In the connection between the main parts of the steel beam and the steel beam of the dome structure , the traditional construction method has two forms. One is the direct welding on site .   Second, the plate is fixed and then welded on site. C rane lifts the steel beam to the joint of another steel beam and the person welds it at high altitude and grinds it flat on site.   Both of the above two methods require welding operation, and on-site welding has the following disadvantages: 1) welding operation requires on-site welding machine to pull wires, which is of high labor intensity and slow construction speed, time-consuming and laborious, and also increases labor cost;2) high-altitude welding is dangerous, easy to cause casualties and cannot guarantee welding quality;4) due to welding deformation and errors, the lighting glass above cannot be processed correctly. Generally, the frame is welded and installed, and the glass is ordered and produced afte...
