2. Encourage the use of steel mesh.
From March 1, 2025, all new housing and municipal engineering scaffolding facades are encouraged to use steel mesh as a safety net.
3. Quality management requirements
(1) When purchasing or leasing disk buckle components, the construction unit shall sign a quality assurance agreement with the manufacturer or leasing unit. The manufacturer or the leasing unit shall provide quality assurance data such as product quality certificate, product instructions (including the main technical parameters of the product), type inspection report (the inspection items must include appearance, dimensional deviation and component strength, etc.), and the type inspection shall be based on the standard of Socket and Spigot Steel Pipe Support Components (JG/T503-2016). The number of samples sent shall not be less than 8 sets. In principle,
a project shall use the buckle components of a manufacturer or a leasing unit. When the quantity of buckled components supplied by one company cannot meet the needs of the same project, the same project shall be strictly divided into areas to avoid mixing buckled components from different manufacturers or leasing units in the same area. The construction unit or leasing unit that purchases the plate buckle components by itself shall formulate and implement management measures to prevent fake and inferior products, adulteration and cross-mixing of plate buckle components from different manufacturers, and the plate buckle components supplied by different enterprises shall be clearly marked.
(2) When the buckled components enter the construction site, the construction, supervision and construction units shall, in accordance with their duties. The appearance quality, outer diameter, wall thickness and product identification on the surface of main buckled components shall be inspected, accepted and recorded according to the requirements of Technical Standard for Safety of Steel Tubular Scaffold with Socket and Spigot Joints in Construction (JGJ/T231-2021) and Steel Tubular Scaffold with Socket and Spigot Joints (JG/T503-2016). The buckled components with incomplete quality assurance data, unqualified appearance quality and without product identification according to the standard requirements shall not be allowed to enter the site.
(3) The construction unit shall promptly entrust a testing institution with corresponding qualifications to carry out testing before the plate buckle components used for formwork support engineering and load-bearing support system enter the construction site for use. The construction unit shall cooperate with the construction unit or the supervision unit to witness the sampling on site, and then send the samples to a qualified testing institution for testing. The number of samples sent shall not be less than 8 sets. The inspection organization shall be in accordance with the current Spigot and Socket Type Steel Pipe Support Components (JG/T503-2016) and Tensile Testing of Metallic Materials-Part 1: Test Method at Room Temperature (GB/T228. If the steel pipe support components provided by multiple units are used, the construction, supervision and construction units shall jointly witness the extraction of the steel pipe support components from all manufacturers on the site for inspection. The disk buckle components that have not been tested or failed to pass the test shall not be used.
(IV) The quality of expanded metal mesh shall meet the requirements of Expanded Metal Mesh (GB/T33275-2016) and Continuous Hot Dip Galvanized and Zinc Alloy Coated Steel Sheet and Strip (GB/T2518-2019). Its impact resistance and penetration resistance shall meet the requirements of relevant parameters specified in Safety Net (GB5725-2009), and its appearance color shall be light blue (color number: RAL 5012). Materials such as steel plate mesh, components and fittings shall be attached with product certificates, quality certificates and product instructions when entering the site, and shall meet the requirements of product design specifications.
4. The main responsibility
of each participant (1) Construction unit
1. For the housing construction and municipal works using the spigot and socket scaffold and steel mesh, the Employer shall specify the use requirements in the draft terms of the construction contract in the bidding documents, and calculate the corresponding costs in the project budget (settlement). When preparing the maximum bidding price limit, the construction scheme shall be reasonably considered, and the relevant costs of plate-buckle scaffolding and steel mesh shall be fully calculated. In the process of
implementation, if the relevant documents have other provisions on the pricing of plate-buckle scaffolding and steel mesh, the new provisions shall be implemented.
