[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - galvanized duct] operating process (a) according to the design requirements and identify baseline reference civil duct elevation (two) and high production hanger hanging Point 1, after the elevation determined in accordance with the spatial location where the duct system, determine the wind pipe support and hanger form. 2, duct support and hanger fabrication drawings refer to "construction equipment construction and installation of Atlas" (91SB6) of material specifications and production practices. 3. Set hanging points: (1) embedded parts method: a pre-embedded: General by reserve officers will coordinate position by drawing embedded parts and support and hanger spacing, securely fastened to the building structure reinforcement. b late embedded: buried in the brick wall bracket: distance from the ground surface elevation is calculated according to the bracket on the steel duct, find the correct installation position works, played 80mm × 80mm square hole. The size of the hole should be the same inside and outside, a large depth than the depth of the wall bracket buried 30 ~ 50mm. Lay hole, the hole in the wall of water pouring wet plant cooling engineering and brick debris out of the cave. Then filling in the hole in the wall the first part of the 1: 2 cement mortar, the stent buried, buried depth is generally 150 ~ 200mm. Leveling bracket with a spirit level, adjust the depth of the buried, continue filling mortar, proper packing some water-soaked rocks and broken bricks and ventilation pipeline projects to facilitate mounting bracket. When filled with cement mortar, should be slightly lower than the wall, wall decoration in order to carry out civil engineering jobs. Buried under the floor hanging pieces: After determining the location of the elevator with the impact of drilling on the floor in a transparent eye, then on the ground picking a 300mm long and 20mm deep grooves. The hanging pieces fit into a groove, the groove filled with cement mortar. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Ventilation Engineering] ventilation and air conditioning construction safety and environmental reasons? 1. undertake the construction of ventilation and air conditioning business should have the appropriate safety production license; construction and installation site should establish appropriate safety and environmental management system, and should be equipped with a full-time safety officer. 2. The pre-construction ventilation and air conditioning engineering safety technical tests should be carried out; in the security measures and facilities construction should meet the relevant requirements of the State; construction equipment shall require the use of appropriate safety procedures. 3. The provisions of the construction process construction site temporary power should be consistent with existing national standards should be taken to ensure the safe operation of electrical equipment and effective measures. 4. electricity, gas welding welding operations, the operator should set up special supervision certificates, and should be equipped with fire fighting equipment; after electricity, gas welding operation is completed, you should carefully check the refrigeration room works, eliminate hidden dangers before they leave. 5. scene handling, while lifting a variety of materials and equipment, should be someone directing and coordinated to avoid injuries and damage to materials and equipment. 6. Large lifting equipment, shall be prepared before shipping special technical solutions to be implemented after approval. 7. operations in an environment of poor air circulation, ventilation should take interim measures. 8. paints, adhesives when brushing should take protective measures, and should keep the air circulating within the operating area. 9. explosive and other dangerous items should be safely stored separately, volatile items should be sealed, and storage of dangerous goods residue containers should be properly recycled. 10. may produce dust, the noise of the construction process operations, dust and noise reduction measures should be taken.
