1 structure installation prior to conduct a comprehensive inspection of components such as the number of components: length, verticality, installation size meets the design requirements;
The 2 component lifting, appropriate measures should be taken to prevent excessive bending and torsion deformation;
3 after the structure is in place, it is necessary to fasten the support and other connecting components in time to ensure the stability of the members;
4 all the lifting of the upper part, must be in the lower part of the structure, correction, and fasten the support component can be carried out after the glass steel chimney before installation to conduct a comprehensive inspection
5 component of the local or overall bending, the ratio of the height and the bending length of less than 1/1000, and less than 20mm;
6 tower, glass steel chimney of each cross section of the center, must be in a vertical line, after the installation is completed, the vertical deviation is less than 1/500;
The center line of 7 tower and each rod must intersect at the center node pestle, the allowable deviation shall not be greater than 5mm, the geometrical position of tower truss design, the position deviation in the plane is less than 4mm, the deviation in the plane design and location requirements of less than 2mm
The 8 tower production, installation, acceptance drawings except the requirements given, should carry out the "" steel structure engineering construction and acceptance of rules "(GB50205-2001)", "petrochemical steel structure engineering construction and acceptance of rules" (SH3507-1999) regulations.
9 tower construction, require the use of effective measures, such as increasing the lifting point pestle or support points to ensure that a single pole is connected with the group when in assembling, the deformation is minimum.
The 10 tower after the installation of anchor bolt and anchor bolts should be quite performance. (must be combined with the basic design drawings)
11 tower, glass steel chimney block assembly, integral lifting, lifting and lifting scheme is subject to the tower equipment is determined by the construction unit for checking, after verification of lifting, and lifting must be temporary reinforcement. Before the installation of FRP chimney to conduct a comprehensive inspection before the installation of FRP chimney to conduct a comprehensive inspection
