1. Check whether the quality of the keel meets the requirements of the drawing and whether the keel installation meets the design specifications. The connection bolts installed on the horizontal and vertical keel are not omitted. In order to ensure the installation accuracy of the board, the erection of the latituder instrument should be used to penetrate the vertical rod, and properly handle the deformation seams, sedimentation seams and cross -section to meet the requirements of the use.
2. Check the construction diagram and on -site measurement dimensions in detail to ensure the improvement of design and processing. At the same time, carefully check the structural node diagram, and find the inconsistent parts, and correct the design as soon as possible.
3. The connection between the connector and the vertical keel should be reliable and not leaky elastic pad.
4. The material and processing geometric size of metal accessories shall meet the design requirements.
5. Check whether the aluminum veneer material, plate surface color, strength, appearance, processing accuracy meet the design and national standards.
6. When the aluminum veneer enters the field, stack it according to the specification number to prevent collision and pollution.
7. Before installing construction, a tripod should be set up. The installation operation shall be accepted by the relevant departments. Check whether the scaffolding meets the requirements of the curtain wall construction and specifications.
