Steel structure gas station advantage
(1) The strength-to-mass ratio and strength of steel is higher. Compared with wood, masonry, concrete, and so on, although its density is larger, its strength-mass ratio and strength are still much higher than the above materials. Under the same conditions, steel members have low dead weight and small cross-sections, so they are especially suitable for large-span structures.
(2) Uniform steel material, good performance, high reliability. At the same time, the internal structure of steel is uniform, which is in line with the ideal isotropic elastic-plastic material and can well simulate and reflect the actual working conditions of different steel structures. In addition, steel processing in the factory, with strict process quality control, and high reliability.
(3) The construction is convenient and the construction period is shortened. Due to the materials are modern professional chemical plants into batch production of finished materials, high precision, good processing performance, easy to spot joint hoisting, and high degree of industrial production, can effectively shorten the construction period.
(4) good ductility, and strong earthquake resistance. Due to the advantages of good plasticity and toughness of materials, high strength, soft structural system, and lightweight structure, when the earthquake occurs, the structure has strong energy dissipation capacity, small earthquake effect, and small damage, to have strong seismic performance.
(5) The space frame, truss joints, and rods are convenient for commercialization and standardized production, which not only improves production efficiency but also promotes novel and beautiful space frame architectural shapes.
Solutions
The gas station project is divided into the new gas station project and the reconstruction and expansion of the gas station project. New gas tanks commonly do not reach the designated position, with no fire danger, so the h-beam structure can be used. It’s a kind of structure form that is a big welding workload. For the reconstruction of the gas station, short construction time, small construction site, has certain fire danger, all bolt connection of steel structure and spatial structure is more applicable, effectively avoiding a large amount of site welding, avoid fire danger. Steel is an alloy of iron and carbon that can contain up to 2% carbon. It is the most widely used material in building infrastructure and industries around the world. Steel has a high tensile strength, which means it can resist large forces without breaking or deforming. In addition, steel can be fabricated into different shapes and sizes, making it a versatile material for various construction applications.
1. Due to the single volume, it is small, and high cost, and because the BJMB way installs quickly, it can carry on the mass design, manufacture, and installation.
2. Site installation does not require welding, but it is safer for gas stations in operation (it should also be closed in case of emergency).
3. The installation and lifting of the BJMB structure are very fast. The installation of the main structure of the general gas station only needs 2~5 days (the area and the structure form are determined) to be able to be fully hoisted into place and transferred to the roof installation.
4. Metal roof lightning protection is better, BJMB space frame roof structure is designed through wind-resistant.
5. The filling station canopy produced by LF has good seismic performance, high rigidity, good integrity, small steel consumption, can effectively withstand dynamic loads, standardized components, is easy to manufacture and install, flexible layout, and a beautiful appearance
Production process: all components are produced in the factory, especially welding, and only need to be bolted according to the number on site.
Installation process: generally, the bolts installed for structures on the ground, are safe and reliable. After the installation is completed, the whole structure is lifted (except the plate, which must be installed in the air). The lifting point must be checked.
Hoisting technology
Given the problems such as long-span, many space frame nodes, poor stability, and difficult installation of steel structure space frame canopy of gas stations and gas stations, the construction method of preassembled steel structure grid canopy and overall lifting on the ground is as follows:
(1) The unit extension bulk method is adopted on the ground, along with the reference space frame, to both sides of the expansion, in this installation sequence extension, until the assembly of the entire space frame is completed.
(2) According to the shape, center of gravity, and technological requirements of the steel structure space frame canopy, 8 hoisting points are selected, the crane station is reasonably arranged, and the whole hoisting is in place at one time, which realizes the safety, efficiency, and accuracy of steel structure space frame canopy installation.
