() Embedded parts should be buried according to the location and specifications required by the design when concrete is poured into the main structure. () In order to ensure the reliability of the connection between the embedded parts and the main structure, the concrete strength grade of the main structure at the connection part should not be lower than.
() The anchor bars of the embedded parts should be placed at the outermost row of main bars of the concrete component. inside. In order to prevent the embedded parts from shifting during the concrete pouring process, the embedded parts should be connected to the steel bars or formwork and fixed during the concrete pouring process. Special personnel should be sent to follow up and observe. If there is any deviation, the embedded parts on the top surface of the beam plate should be corrected in time. Generally, the concrete pouring and tamping are carried out simultaneously, and the concrete under the embedded slab should be vibrated and compacted.
() Before pouring concrete, the concealed project acceptance should be carried out. The acceptance content includes the specifications, model, location, quantity, anchoring method, anti-corrosion treatment, etc. of the embedded parts.
() When welding on the anchor plate surface of embedded parts that have been embedded in concrete structural components, high temperature burns to the concrete should be avoided. The surface of the anchor plate of the embedded parts exposed on the structural components should be painted with anti-corrosion paint in time after welding the curtain wall connectors.
() When the curtain wall is connected to the masonry structure, it is advisable to add reinforced concrete or steel structure beams and columns to the main structure of the connection part. Lightweight infill walls should not be used as supporting structures for curtain walls.
