What are the main contents of the 'three test' of curtain wall performance testing

1. The test includes wind pressure deformation function, air-tight function and water-tight function, which is usually called 'three-character experiment'. If necessary, the in-plane deformation function and other function detection can be increased. The so-called 'four natures'. 2. The angle steel and channel steel do not need to be retested. The materials that need to be retested in the curtain wall project are: 1. The peeling strength of the aluminum-plastic composite panel; 2. The tortuous strength of the stone, the freezing and thawing resistance of the stone in the severe cold area, and the granite for indoor use. 3. The Shore hardness of the structural adhesive for curtain walls, and the tensile bond strength under the standard premise; 4. The staining property of the sealant for stone; 5. The structural sealant and weather-resistant sealant for the curtain wall and the contact materials Compatibility and peel adhesion test (these two index sealants cannot be supplied in the factory exam lecture, but must be re-inspected before sealing and use) 3. Sampling quantity of re-inspection materials: among the materials that need to be re-inspected, at least one set of samples of the same type and type of entry materials produced by the same manufacturer shall be selected for re-inspection. When the contract is otherwise agreed, it shall be in accordance with the contract. fulfill. 4. Field experiments are required: 1. On-site drawing experiments of post-embedded parts, the number of samples should be randomly sampled in accordance with the ratio specified by the standard; 2. The peeling experiment of silicone structural sealant, extraction The quantity is 1 piece for every 100 components. The building curtain wall is composed of a supporting structure system and panels, which can have a certain displacement relative to the main structure, and does not share the external protective structure or decorative structure of the building that is affected by the main structure. 3. For curtain walls with special shapes or special requests, the division of examination batches and the inspection quantity of each examination batch should be based on the structure of the curtain wall, process characteristics and the scope of the curtain wall project, and the supervision unit, construction unit and construction unit shall negotiate and judge. 4. All water spray experiments are carried out. V. Examination batch division: 1. Curtain wall projects with the same design, materials, craftsmanship and construction premise are an examination batch for every 500~1000 square meters, and an examination batch for less than 500 square meters; each examination batch is every 100 square meters The meter should be spot-checked in at least one spot, and each spot should not be less than 10 square meters. The curtain wall is composed of a structural frame and inlaid panels, and is a building envelope that does not bear the load and role of the main structure. 2. The discontinuous curtain wall project of the same unit project shall be divided into examination batches separately. The door and window curtain wall is composed of a panel and a supporting structure system (supporting device and supporting system), which can have a certain displacement capacity relative to the main structure or a certain deformation capacity by itself, and does not bear the effect of the main structure. 3. For curtain walls with special shapes or special requests, the division of examination batches and the inspection quantity of each examination batch should be based on the structure of the curtain wall, process characteristics and the scope of the curtain wall project, and the supervision unit, construction unit and construction unit shall negotiate and judge. 1. Lectures on the mechanical function test of aluminum alloy profiles 2. Lectures on the test of insulating glass and optical function of heat-reflective glass 3. The structural silicone adhesive peeling experiment, the compatibility of the silicone structural adhesive sealant and the substrate for actual engineering Sex test lecture 4. Four-sex test unit glass curtain wall and frame glass curtain wall of the curtain wall. Inspection list Plate embedded parts, channel embedded parts, chemical anchor bolts, raw materials of steel, aluminum profiles, glass, aluminum plates, thermal insulation cotton, fireproof cotton, structural glue, bolts, curtain walls, stone, EPD M, rubber strips.
