JG 3002.3-92 table 1It is.7 inspection rules7.1 the railings and armrest components must be inspected by the factory inspection department before they leave the factory.7.2 inspection items and methods shall be in accordance with the provisions of appendix A, housing stair railings, handrails inspection items and methods.7.3 batch and sampling7.3.1 for a batch of normal production according to the same component type and the same process.7.3.2 in appearance quality watch one by one, on the basis of random by 5%, and total sampling amount not less than 3 pieces, the batch is more than 300 pieces, random by 2%, and the total amount of sampling observation is not less than 10 appearance quality and allowable deviation measurement inspection.7.3.3 the inspection of structural performance shall be testedat random in the components of the half-year normal production.7.4 quality assessment principles:According to the evaluation, ensure project must conform to the requirements, major projects must meet their requirements, general project, classy article must be not less than 6 items conform to the requirements, the product must be not less than five requirements, product must be no less than four requirements.7.5 acceptance principles:In the railings and handrails of the sampling inspection, the rate of grade is less than 90%, and the batch of products shall be inspected according to grade one. The grade of the first grade is less than 90%, and the products shall be inspected according to the conformance products; If the qualified rate is less than 90%, the batch of products should be redoubled and the qualified rate is still less than 90%, so it should be repaired completely.After inspection of the re-built railings and handrails, all of them shall be inspected according to the conformance, and the repair methods and inspection results shall be recorded and archived.8 signs, packaging, piling and transportation8.1 the factory name (factory standard), product code, production date (year, month, day) and production team shallbe marked in obvious place, and the inspection result shall be based on the inspection result.8.2 manufacturer supply products, unit must issue a "certificate of approval" consign is used, must be marked "certificate" : the standard number, certificate number, project name, code, the weight of components, production and manufacture date, quantity, structure, performance, quality grade, etc.8.3 stair railing and armrest shall be packed into groups according to quality grade, and each group shall weigh no more than 80kg. The packing should be firm, deformed and damaged.8.4 railings and handrails should be stacked, transported and prevented from deformation according to the model.The building has the quality of the air guard railRelease date: 2007-3-20The building has the quality of the air guard rail1. The safety height of the protective handrail (panel) shall conform to the requirements of the current general principles of civil architecture design and corresponding architectural design specifications. The height of the building design specification is the clearance height above the surface layer, and the first decorative room must deduct the thickness of the corresponding surface layer. The height of the safe height should be calculated from the step surface. Note: when the rail(board) at the bottom for solid and height is less than 450 ㎜, rail inside solid surface width is greater than 65 ㎜, in fact heart body level shall be deemed to tread.2. In the case of glass protection, shall implement the "regulations of technology of architectural glass application", "building decoration engineering quality acceptance specification" and so on the current standards and regulations and the provisions of this point, as well as the regulation on administration of construction safety glass (sent to run [2003] 2003). With metal materials for protection, should comply with the specifications for design of steel structure, the construction steel structure welding technology regulations, the construction quality acceptance of steel structure engineering and the rebar welding and acceptance procedures such as the current rules and regulations and the provisions of this point.3. Residential buildings and places with children's activities, protective railings (panels) must be constructed to prevent children from climbing, and the clearance of vertical bars must meet the requirements of the relevant codes.4. When using glass as a protective railing (board), the laminated glass or tempered laminated glass must be used. When exterior decoration is the glass curtain wall, the inside should take protective measures according to the requirements of "building glass technical regulations", the height should meet the design requirements. A reliable guardrail must be used on the inside of a high body or glass falling after a collision.5. The materials, specifications, quantities and the combustion performance of the materials used in the fabrication and installation of protective railings (plates) shall meet the design requirements.6. Protective railing (board) of construction shall be in accordance with the requirements of design and specification before the construction of the "template", by the relevant units to check for the installation of large area, until they have passed the acceptance check, shall provide certificate of raw materials, the reinspection report and related inspection report.7. Guardrail height, rail spacing and installation position must meet the design requirements. Guardrail installation must be firm. The link between the hand guard and the upright post and the structure of the main body must take reliable measures, which shall not be directly buried or welded to the expansion bolt.The railings should be smooth and should not have burrs.8. The number, specification, location and connection of the embedded parts of the railings (plates) shall conform to the design requirements. Weld metal, plastic railings and handrails must be soldered. The embedded parts (or rear embedded parts) shall be connected to the node, and the lightning protection connection shall be accepted for concealed work.9. The coating of handrail (plate) should be uniform, withoutobvious wrinkling, falling, no leakage brush, and good adhesion. Metal railings descaling grade and total dry film thickness of coating should comply with the design requirements, should check the adhesion of coating and coating of examination and acceptance of the total dry film thickness of design should press when no request for construction quality acceptance of steel structure engineering, execution, and have corresponding record data.10. The construction of the next procedure shall not be carried out after the construction of the protective railings (board) has been completed, and if it is not accepted or unqualified.11. The construction of housing units should be handed over to the housing issue a railing airport protection such as reasonable use fixed number of year and the rational use of specifications, building manager (project owner or management) in the process of the use of housing should be according to the directions on the rail and airport protection for regular inspection and maintenance. When the use life exceeds the reasonable period of use determined by the design, after the inspection unit is identified, effective measures should be taken to continue the use.。
