This article describes the membrane structure installation instructions; general construction methods and processes. Mainly include steel site assembly, painting process, membrane fabric installation process and other three areas. Structure construction: a steel structure assembled a live, on-site assembly preparatory work before (1) week prior to the first section ready to be shipped to the factory-supplied tools and equipment transport to the site, and to achieve water and electric power supplies and roads; (2) the same car shipped to supporting the tire rack crossed, positioning, re-inspection and welding fixed. 2, component-site inspection component inspection and acceptance. In accordance with design drawings and related specifications, after entering the installation site member to deal with their identity, quantity, quality look carefully examined, and make inspection acceptance records. Unqualified members, must not be allowed to enter the installation and acceptance process. Member temporary stacking. After acceptance component approach, you should choose a higher plain of the lot as a temporary stacking venue. When placing components, sufficient number pad below the skids to prevent deformation. To classify stacked components easier to find. Secondary unlucky member. When the member by stacking space for secondary unlucky to assembly site, to choose the right lifting point and take the necessary measures to avoid injury or damage to components. 3, the installation process plan ground work platform on-site installation work. (1) each component or components before installation, to make their mark, geometry, and other installation pitch careful examination, after confirmation, before installation; buried precision (2) checking whether the measurement of embedded parts consistent design drawings; (3) will be on supporting the tire rack and lifting the roof and the ceiling mount bracket temporary configuration in place; (4) the mast segments and other parts on the car with a crane hoists; (5) on the mast installed membrane After tensioning device rigidly connected securely; (6) connected to the mast and the mast in the middle and temporary lifting bracket in place, then the other two transverse truss assembly molding, with a temporary bracket in their respective predetermined position; (7) from Central to both sides began successive longitudinal frame and tack-welded in place. Precise measurement location, shape, relative distance and other parameters are correct positioning welding; (8) until the end of the 24 hours of all welding work carried out to measure the completion of the entire architecture to the Party inspection supervisors. Second, the coating process of the project using the new special anti-corrosion coatings - solvent-free liquid epoxy anti-corrosion coatings. Solvent-free liquid epoxy anti-corrosion coatings in addition to a solvent-based epoxy coal Lek table excellent antimicrobial resistance, excellent chemical stability, but has the following outstanding features: 1, a good anti-permeability, low water absorption; 2, sticky knot strength, excellent resistance to cathodic stripping performance; 3, the construction of non-solvent evaporation, the effective elimination of pinholes ills; 4, a film thickness, construction and high efficiency; 5, the paint is non-flammable, explosive materials, construction safety and health . In order to shorten the construction period. With steel truss plant whole painting, transportation, making up painting after installation. 1, rust require protection in order to obtain good film properties and surface treatment effect, first do the following after welding: (1) metal surface should be free of oil, sand-blasting the surface should reach Sa2.5 level, anchor pattern depth of 50μm around; if limited conditions, can also be hand-rust, but must reach St3 level. Clear steel surface dust. Wire brush application concrete surface treatment required to achieve no dust, no oil, no water, no alkaline. Repair undercut, remove weld spatter, slag; (2) the cutting edge, sharp edges and corners drilling, punching, grinding, radius ≥2mm; (3) the cutting edge, sharp edges and corners drilling, punching, grinding, round corner radius ≥2mm; (4) the tower surface should be no bumps, no holes, no indentation, suitable for painting; (5) blasted steel surface before the oil and other contaminants to clean up. 2, coating application (1) a coating formulation: BH-100 is a two-component coating, A component is the main component of the paint, the component B is a curing agent. The coating A, B components can be carried out later in proportion Stir construction, the original two-component coating fixed mixing ratio packaged together, stir to evenly brushing; or how to group A, according to usage sub: B component = 100: 10-15 were mixed, stir. According to the temperature, the stand 0-30 minutes after brushing; (2) coating application: Airless spray paint can, paint brush and other methods. Under a paint should be applied after a paint dry. Paint should be within the specified time runs out, you can add solvent dilution does not exceed 3% of the coating viscosity is too large. Or if the paint is fully cured, should play together under the hair before brushing paint; (3) the entire plate surface coating process should be higher than the lowest temperature above the dew point temperature of 3 ℃, relative humidity of air does not exceed 85%; (4 ) it is difficult to position the spray paint before welding, etc. should be pre-coated to ensure that the film thickness meet the requirements; (5) Construction of paint and construction conditions should be strictly in accordance with the technical requirements of paint manufacturers product specifications implementation; (6) After the road paint before painting, such as exceeding the prescribed maximum recoat time, the application sandpaper to clean the surface of the rear surface of the nap, and then spray paint the next one; (7) in each frame after painting is completed, must wait for the paint dry and hard after conducted before lifting, or allow workers to other jobs. 3, coating repair (1) coating damage caused during transport or assembly should be arrived at the scene within an appropriate time repair; (2) on-site repair when the weather conditions, the technical parameters of the paint should be consistent with the paint specification requirements or Compliance paint technology represents guidance; (3) coating quality requirements and test methods; (4) coating the surface can not appear bubbles, holes, waste, transport process can not occur scratching, peeling phenomenon; (5) the gloss topcoat 30 to 40; (6) the construction unit to deal with the whole process of painting to be recorded, including: painting environment, surface treatment levels, construction methods, DFT, working time, date and operator construction and so on. Third, the film is a fabric installation process, the construction preparation (1) Check the site of machinery and equipment are safe; (2) to convene site worker speech to explain the installation steps and precautions; (3) to clean up the workplace and in the heart of the film cloth sheets Open to prepare; whether the center wedge eye (4) Check the steel membrane fabric on a model consistent; (5) the closed road near the scene, such as the need to place the fence; new material (6) Check on site, whether categorized , on a clean ventilated place; (7) review of the material, to ensure that all the material fully qualified arrived at the scene, while clearing substandard materials; 2, according to the site of the construction scaffolding erected scaffolding erected to a height of one meter at the top. 3, membrane cloth (1) Preparation of the film opens on a clean cloth moisture cloth; (2) the membrane is folded in half longitudinal tape, and then make it into a free sandwich cloth-like film; (3) Temporary membranes place; (4) ensure that all adjustments are beneficial; (5) the cable system in the lower bottom to ensure that the end of the rope rigging system; and (6) into the edge of the rope, cloth and film fit; (7) The rope tied to the cornea cloth; (8) the rope tied to one end of a high point, so that these ropes over film distribution; (9) the latches on the metal plate membrane fabric on steel mate; ( 10) to check whether all the latches on the requirements of the design; (11) Check all shrouds, equipment and accessories are really claw; (12) cleaning cloth membrane; (13) to review the implementation of all the parts are in place, while the clean-up debris. 4, laying (1) the film to the pavement hanging position; (2) with a rope fasten securely to keep the fabric loose hold state; (3) the loose membrane and spinal cord were pulled up to the junction of four weeks; (4 ) connected around the contact plate and install cable ties to secure it firmly. Note that the film holding the loose hold state. 5, tensioned membrane (1) Check the contact surface, all the steel parts are securely connected membrane structure; (2) the film is laid to the specified location, while paying attention to cooperation and coordination, maintain its stability; (3) finished with a rope deduction will be firmly fixed; (4) finally put layering.
