1. The acceptance project includes the installation and anti-corrosion treatment of the main structure and columns, columns and beams. Fire prevention and insulation installation of curtain wall. Installation of expansion joints, settlement joints, shockproof joints and yin and yang corners of curtain walls.
Installation of lightning protection nodes for curtain walls. Sealing installation of curtain walls.
2. The curtain wall is the outer wall enclosure of the building, which is not load-bearing and hangs up like a curtain, so it is also called "curtain wall", which is a lightweight wall with decorative effect commonly used in modern large-scale and high-rise buildings. A building envelope or decorative structure composed of panels and supporting structure systems, which can have a certain displacement capacity relative to the main structure or a certain deformation ability of itself, and do not assume the role used by the main structure.
3. The curtain wall is the use of a variety of strong, light and beautiful building materials to replace the traditional masonry or window wall combination of the exterior wall construction method, which is surrounded by the periphery of the main structure and makes the whole building beautiful, using a sound and safe exterior wall construction method. In short, it's about putting on a beautiful coat of architecture. The scope of curtain walls mainly includes the exterior walls of buildings, lighting roofs (canopies) and canopies.

1. If the supervision is strict, you will immediately carry out the pull-out test of the chemical anchor after you plant the chemical anchor.
2. After the chemical anchor bolt is qualified, the keel should be installed, and the keel should be fully welded after the installation is completed. The strict supervisor wants you not to paint after full welding. He is optimistic that the weld meets the requirements before he can brush the anti-rust paint and silver powder paint.
This is the concealed acceptance) It stands to reason that the concealed acceptance should be accepted by the local quality supervision station together with the supervisor and the quality inspector of the general contractor.
3. The next step is the lightning protection of the curtain wall, which is generally to find the supervision of the pipe electricity, and to prepare an ohmmeter to measure the resistance.
4. After the concealment and lightning protection acceptance, you can install the panel, do not glue after the panel is installed, and the general supervision depends on the condition of your screws, mainly the spacing of the screws. It's good to glue after no problem, and it's good to accept the panel after the glue is laid.
The above are the basic requirements for construction. If it is to make materials, it is generally concealed acceptance, lightning protection acceptance, and panel acceptance.

What curtain wall? Generally, the anchor hole behind the curtain wall (anchor hole location, hole depth, hole diameter, verticality), anchor bolt (anchor depth, verticality, preload, position control, etc.), anchor bolt uplift bearing capacity, etc.
If it is a construction quality acceptance, the anchorage quality behind the curtain wall and the curtain wall itself (such as glass curtain wall, metal curtain wall, stone curtain wall) are accepted in batches. The specific inspection items are found in the corresponding construction specifications.

Dear, hello, I am happy to answer your questions, curtain wall engineering construction and installation should focus on inspection. 1.The following documents and records should be checked during the acceptance of the curtain wall project:
1) Construction drawings, structural design calculations, design descriptions and other design documents of curtain wall engineering. (2) The confirmation document of the curtain wall engineering design of the architectural design unit. (3) All kinds of materials, hardware accessories, structural parts, and components used in curtain wall engineering are made of product certificates, performance inspection reports, entry acceptance records and re-inspection reports.
4) Confirmation certificate and random inspection certificate of silicone structural adhesive section for curtain wall engineering; Commodity inspection certificate of imported silicone structural adhesive; Silicone structural adhesive compatibility and peel adhesion test report issued by a designated testing institution; Stone sealant pollution resistance test report. (5) On-site pull-out strength test report of post-embedded parts. (6) Test and report the wind pressure, air permeability, rainwater leakage and plane deformation of the curtain wall.
7) Record the temperature and humidity of the gluing and curing environment; Records of two-component silicone structural adhesive mixing test and tensile test. (8) Lightning protection device test records. (9) Concealed engineering acceptance records.
10) Curtain wall components and components manufacturing records; Curtain wall installation record. The curtain wall project should re-inspect the following materials and their performance indicators: (1) the peel strength of aluminum-plastic composite panels.
2) the flexural strength of the stone; Freeze-thaw resistance of stone in cold regions: radioactivity of indoor granite. (3) Shore hardness, tensile bond strength and compatibility test of structural adhesive for glass curtain wall under standard conditions; Bond Strength of Stone Structural Adhesive:
Contamination of stone sealants. The curtain wall project shall accept the following concealed works: (1) embedded parts (or rear embedded parts).
2) Connecting nodes of components. (3) Structural nodes at deformation joints and wall corners. (4) Curtain wall lightning protection device.
5) Fireproof structure of curtain wall. The inspection batch of each sub-project shall be divided according to the following provisions: (1) For curtain wall projects with the same design, materials, processes and construction conditions, an inspection batch shall be divided into one inspection batch for every 500-1000 square meters, and an inspection batch shall also be divided for those less than 500 square meters.
2) Discontinuous curtain wall projects of the same unit project should be divided and inspected separately. (3) For curtain walls with special shapes or special requirements, the division of the inspection batch cavity reputation shall be determined by the supervision unit (or construction unit) and the construction unit according to the structure of the curtain wall, the characteristics of the process and the scale of the curtain wall project. The inspection quantity shall meet the following requirements:
1) At least once per 100 square meters of each inspection batch, not less than 10 square meters per place. (2) For curtain walls of special shapes or special requirements, the division of inspection batches shall be determined by the supervision unit (or construction unit) and the construction unit through consultation according to the structure, process characteristics and scale of the curtain wall project. The curtain wall and its connecting parts should have sufficient bearing capacity, stiffness and displacement capacity relative to the main structure.

rear bolt connectors;
the connecting node between the member and the main structure;
Blockage around the curtain wall, between the inner surface of the curtain wall and the main structure;
curtain wall corner node;
curtain wall lightning protection connection node;
Curtain wall fire prevention and insulation nodes.
The requirements of the base surface include the roughness of the base surface, the moisture content and flatness of the base surface. If it is an old wall, it is necessary to see if there is peeling, cracking, etc., if there is a peeling and cracked part, scrape it with mortar or water-resistant putty; If you don't scrape it directly with water-resistant putty. If the requirements are very high, you also need to do back cover processing, polishing and other processes.
You're lazy enough to write all the questions.
