2025-07-09I.Maintenance and upkeep of the space frame structure itself
01. space frame installation completed in the use of space frame, can not be placed on top of the space frame more than its load weight, if there is a roof needs, should be a distance from the space frame to build the position, not directly on top of the space frame, miscellaneous goods are not suspended loaded on top of the space frame. When dismantling the rack should pay attention to synchronization, step by step dismantling, to prevent stress concentration, so that the space frame does not produce local deformation, or make the local mesh deformation
02. If the open-air use of the space frame, it is best to rust the product before construction to protect the role of corrosion in the space frame processing plant or on-site construction, the anticorrosive work should be done in place. Otherwise, under the influence of external acidity and alkalinity, the corrosiveness of the space frame will cause a serious blow to the service life of the space frame processing. After the installation of the bolt ball space frame, you should check whether the holes on the bolt ball are closed, should putty to fill the holes and the gap of the cylinder sleeve and then paint, to prevent moisture infiltration, so that the ball, the rod of the silk buckle do not corrode.
03. after the completion of the construction of the space frame, it is best to carry out maintenance and maintenance every once in a while, for the use of longer life requirements of the space frame more need to increase the frequency of enclosure inspection, and often observe the state, to protect the use of the space frame safety.
04. After the installation of the steel space frame, such as the need to use the crane to lift purlin or roof panels, should be gently held and put, and forbidden to hit the space frame to make the space frame deformation.
II.Maintenance and care of the space frame rubber bearing
01. Support use period regularly, every check, and maintenance.
02. Check whether there is any damage to the support and the upper and lower connectors, check whether the bolts are sheared or loose, and whether the welds are cracked, etc.
03. Check the accumulation of dust in the dust cover and remove the dust.
04 . Check the rubber seal for cracking and aging.
05. Spin the fixing nut, clean it, and re-oil it to avoid rusting.
06 . Check the height change of the support itself, and if this change reacts to the abrasion condition of the PTFE plate. When the height change is more than 4㎜, it should be overhauled.
07. Check the anti-rust paint intact, degrease; if there is peeling off, apply the emery cloth to grind out the steel body and present the metallic luster after repainting.
08. After the occurrence of special circumstances (such as earthquake, destructive wind, etc.), the above should be checked in time.
III.Maintenance requirements for the descaling process during machining
01. Grass-roots level clean up thoroughly, using special equipment for grinding rust or sandblasting rust, rust removal after the grass-roots level shall not have rust spots, oil, grease, sand, dust, sand and metal oxides, et c. clean up.
02.rust, must be sprayed within six hours of the primer for anti-corrosion treatment, spraying process, such as the case of rain or other conditions that cause the substrate steel surface moisture, to be the environment to achieve the construction conditions, with dry compressed air to blow dry the surface after the moisture rust
03. descaling the surface of the steel after descaling to achieve the descaling grade Sa2.5, the surface of the brush and other tools to clean, to carry out the next process, descaling qualified After the steel surface shows a metallic luster, each square meter of metal surface rust spots and paint shall not be greater than 5%, such as in the primer has returned to the rust, re-polishing rust or sandblasting rust, do not reduce the requirements of abrasive, so as not to reduce the roughness.
