  The advantage of space frame  structure is that all components can be processed by factory and assembled on site.   It takes only 45 days to two months for the roof of a large industrial plant,  It will takes 8 to 12 months if the building is made of reinforced concrete. The short duration of the project greatly reduces unnecessary costs. Due to  the light weight of the space frame structure itself, generally do not need to do pile foundation, can save investment.  According to the current market price in China, the cost of light steel structure is lower than that of reinforced concrete structure. When the span of the space frame structure is larger, the use space can be greatly increased, and its advantages are more obvious, it is also a competitive advantage. Generally, the span of truss design is about 20 meters, but the span of space frame can be designed up to 120 meters. Due to the amount of steel used in the space frame structure does not increase ...

  The design of the space frame  should conform to the principle of simplification. The space   frame  is a statically indeterminate form of spatial structure. In the design process, it is impossible to accurately calculate the internal force of the space structure and the conduction or evolution of the deformation, so the design is full of complexity and arduousness.Researchers in the construction industry at home and abroad will usually simplify the calculation of the stiffness of each space node and the deformation of the chords of the space frame  as much as possible while meeting the construction requirements when designing. Thus, the design is not overly complicated, while taking into account the quality of the project and the stability of the  space frame . The second is the principle of safety. Safety is the lifeblood of the construction industry, especially the space frame  occup ying a large space, no matter in the design or construction stag...

  The space structure is exposed to the air for a long time. When the air humidity is too high, a water film will form on the surface of the steel grid, which will corrode the anti-corrosion layer and embroider.Especially in seaside cities, heavier salty places, which are more likely to cause rust on the space frame. Therefore, the rust removal and anti-corrosion maintenance works are more important. When the anti-corrosion layer of the space frame can no longer continue to work, it is particularly important to carry out the rust removal and anti-corrosion maintenance project.The three main points of the anti-corrosion maintenance: good surface rust removal work, high-performance materials, and the thick anti-corrosion and anti-rust coating. Surface treatment is very important. Good  treatment  work can make anti-rust effect 3-5 times better , under the same paint, the same environment, and the same coating thickness. The stains and rust spots on the surface of the steel...

After the completion of the membrane structure to attach great importance to maintenance to ensure the use, which is different from the general building. Long-term maintenance of membrane structures should be carried out by professionals. In general, within one year of completion of the project, 1-2 routine inspections and maintenance of the membrane structure are required. If necessary, pretension reinforcement or other measures should be taken, such as if the connections are loosened, they will be re-tightened or reinforced. The stability of membrane structure depends on the maintenance of pre-stress in the membrane, and the level of prestress affects the deformation of the film under load. If the prestress is too low, the membrane will produce a large displacement and vibrate under the action of the wind. The accumulation of dirt on the membrane surface is related to the local environmental conditions, the characteristics of the membrane material and the shape of the membrane surfac...

Now the space frame  structure has become a common form of architecture in our society. Today, I would like to introduce the characteristics of the space frame  structure: 1.According to the composition of the space frame , it can be divided into the cross truss system composed of two or three plane trusses, and the spatial angular cone system composed of triangle or quadrangle cones, etc. 2.According to the structure composition, it is usually divided into two or three layers  space frame. 3 .A ccording to the supporting situation, there are peripheral support, point support, peripheral support and point support mixed forms.

  The structure of the space  frame is a commonly used form of roofing in large-scale sports stadiums, industrial plants, cinemas, terminal  halls and other buildings.This kind of structure relies on the force of the steel body itself, and the rods are connected together with bolt balls to support each other in a staggered manner, and the net is formed into various roof spaces with different shapes.Conference rooms from small to several meters to industrial plants with spans of several hundred meters are suitable for the structure of the space  frame . Space frame's style is stretched out. It covers both the rhythm and beauty of classical architecture and the romance of modern plastic arts. More and more architects are using its ruggedness and artistry to design and construct large roof skeletons. This novel and beautiful mesh structure has created a new image of the modern building. The steel space frame  structure is used in many large venues today. From an a...

  The space frame bolt ball i s precise   finished component s, which  must be stored in a  clean place with baffles around to prevent rolling and falling off. If the site conditions permit, the steel stamp number of each ball shall be re-marked with eye-catching colors so that the ball can be found as soon as possible during construction. It is not allowed to store the ball in a muddy environment. It must be covered with a tarp on rainy days and before get off work to prevent the ball hole from being damp and rusty, which will affect the tightness of the high-strength bolts.According to previous construction experience, it will have a great safety impact on the space frame if constructed by rusty or impure bolt-ball holes.Therefore, the grid bolt ball must be paid more attention to when entering the field.

  Why the space structure  is the best choice for large-span buildings? Because the space structure  can be realized  with small rods to meet  a large-span structure . The grid structure occupies a small space, can effectively use and save the space. Space structure has the characteristics of triple stress, which can withstand various stress effects. Generally, the internal force structure can be adjusted according to the force requirements of the space structure, which has high safety. For the space structure, the aerial crossing members both bear the force and play a supporting role, thereby ensuring the integrity of the grid engineering and ensuring the stability. The space structure has high rigidity, can bear symmetrical load and concentrated load, and has good seismic resistance .

  1.  After the grid structure  is installed at high altitude, the distance between the grid and the support should be adjusted. For this reason, several groups of chain jacks should be installed above the grid for horizontal adjustment. 2.  Check the overall elevation of the grid to prevent uneven height. The elevation and horizontal distance should b ecome  one end first ly , and the steel tube should be inserted for connection. Tighten the inverted chain on one side and loosen the inverted chain on the other side so that the distance gradually becomes appropriate . 3.  After the adjusted bar on one side is fixed gradually, relax the inverted chain on the other side and continue to fine-tune the elevation of the grid on the other side. The fixed side of the grid should also be observed while adjusting to prevent open welding 。 4.  After adjusting the elevation of the grid frame  in  the other side , tighten the distance with inverted chain,...

  Steel space structures  ha ve  been widely used, and only space structures that meet safety standards can be used in buildings. The first thing to test  is the material used for space structure. Although they are all steel, steel can also be divided into many kinds. Different steel adoption will affect the quality of the entire space frame, so here is also one of the focus of quality inspection. The next step is to check whether the design of the entire steel frame is reasonable. This is a very important product of spatial structure, if the design is defective, it will not take long to produce quality problems, and even seriously threaten the lives of people . Therefore, the design drawings are also required to go through the review of the examination before implementation phase. The third is to be in the installation process of on-site supervision, supervision of the order of installation and methods, whether the site has been cleared to achieve a safe environment...

  Snow load is also an important load on the steel structure of the space  frame. Snow load is a sensitive load for the structure of a large - span, and in many countries there have been accidents in which the steel structure of the space  frame collapses on a snowy day. Snow loads must be considered in cold areas with snow, as well as even roof distribution, uneven distribution and semi-uniform distribution. There are three main reasons that affect the distribution of snow load in the roof, namely, the wind factor, the roof shape and the roof slope factor. Snow loads that are unevenly distributed in the steel structure of the space  frame will generally have a controlling effect, and in the regulations, snow loads are generally considered at the same time as the dust  load.
