So the first job as a curtain wall installation, buried both for its manufacture and installation are directly affects the entire curtain wall construction, installation, and an important factor in the overall effect. 2. material specifications: the embedded parts. 3. basic operation: (1) familiar with the drawings: installation personnel after receivingtypeset by the owners ' consent before they can purchase and order under the program, each stone must use the same background, the same pattern, size error in 0.5mm stone. Air infiltration properties, stone curtain wall wind pressure rainwater leakage in distortion performance, performance and energy-saving performance in front of the construction should be in accordance with the construction plan of the specification and the file size in the appropriate authority inspection departments qualified testing. Stone used steel keel, installation job main including following steps: 2.1 construction Qian prepared 2.2 pre buried pieces processing 2.3 measurement and the measurement results figure draws 2.4 vertical box positioning put line 2.5 turned received pieces installation 2.6 vertical box installation 2.7 vertical box correction and acceptance 2.8 layer high and the cross box measurement positioning and put line 2.9 cross box installation 2.10 installation 2.11 stone plate installation 2.12 sealed rubber injection 2.13 clean ending 2.14 construction Qian prepared 1. Description Project Manager required for the duration of the project schedule, technical information, tools, machinery, apparatus, materials, personnel, temporary facilities ready. 2. the scope of previous construction (1) project outline: to understand the site profiles, familiar with the construction and supervision of party that construction site clean, consciously maintain sanitation. (4) ensure the safety of materials and semi-finished products. 8. quality assessment, data compilation: buried, belongs to the concealed works construction, therefore its quality inspection must be carried out according to acceptance of concealed work-related. Mainly in the following aspects: (1) acceptance of positioning is accurate. (2) is fixed securely. (3) tightening compliance requirements. (4) have an impact on other projects. (5) the material used is eligible. (6) complete information has been collected. Documentation: should follow construction progress at any time finishing self acceptance, signature acceptance after the representatives of the party were invited. Requirements: (1) covert acceptance is thea the company's situation, familiar with the period schedule master plan, construction with water, power supply, vertical transportation, gondola of external scaffolding or construction. (2) technical data preparation: first drawings to prepare the drawings to be fully familiar with, and does not have difficult places to ask out clearly understood, you also need to prepare acceptance of the Atlas, the quality standards, safety index, all the forms used and the acceptance required for the works, and more. (3) tools, implements preparation: supply planning against the required tools, appliances, specific to the type, quantity, supply time, also plans to supply, warehouse, and other departments, common tools and appliances. (4) materials: according to the drawings and engineering, detailed material supply meter ... (2) preparations into people, and clear accountability to specific persons. (3) implementation of collaboration and cooperation with construction companies. 2.15 embedded part installation (early works with civil engineering completed) 1. Note: buried is one of the curtain wall with main structure connecting structure, embedded quality directly affects the production, installation of curtain wall and the main structure of the connections. Its installation has a direct impact on the degree of precision of curtain wall construction accuracy and surface quality is good or bad.
