(1) The size of the glass plate is 4500mm*3250mm, the glass plate is laminated hollow glass, and the plate is attached with aluminum plate decorative lines. The weight of the heaviest plate is 1650Kg, and part of the glass surface is 950mm away from the beam edge of the concrete curtain wall structure. In the design, the overall plate falling problem caused by the distance between the glass surface and the unit support is considered. In order to solve the above problems, the glass unit plate adopts the seated design mode, that is, the dead weight load of the glass plate is borne by the aluminum plate below it. The specific implementation method is as follows: a horizontal slide block is set in the sink material of the upper beam of the aluminum plate, and a rib plate is set on the horizontal slide block to support the upper glass plate column and the lower beam, and the position of the horizontal slide block corresponds to the upper glass plate column. The top of the glass plate is steel frame, 120*80 steel pass is adopted, and a 18mm thick connecting plate is welded at the end of the steel pass.
The connecting plate is connected with the L-shaped aluminum alloy connector through bolts, and the L-shaped aluminum alloy connector is directly connected with the plate trough embedded part at the bottom of the curtain wall facade through t-shaped bolts. Vertical waist holes are set on the 18mm thick connecting steel plate, the plate can realize up and down displacement at the waist hole position, to meet the requirements of temperature deformation and plate layer displacement expansion. Through the above node structure, the installation of the large glass plate is relatively simple. After the plate falls on the aluminum plate, the position of the L-shaped aluminum alloy connector is adjusted immediately, and the connecting bolts of each part are tightened.
(2) The plate is attached with 150mm*700mm vertical aluminum plate decorative lines, and the force transmission and limit of its cross-wail load are most easily ignored by curtain wall suppliers, especially the insertion position of the upper and lower units. It is necessary to consider how to transfer the cross-wail load of the upper plate to the lower plate. In the position of the plate with 150mm*700mm vertical aluminum plate decorative lines, aluminum alloy limit members are set on the upper beam of the lower plate, and the limit members are inserted into the vertical keel of the upper plate to form cross-wale load transmission. In addition, the project adopts the plate and groove embedded parts.
(3) The modeling of the project plate is complex, so it is necessary to focus on the design of processing, transportation and lifting point. When assembling plate and transporting plate, it is necessary to consider the stability of plate lying flat, and adjustable tire rack should be designed according to plate type, so that plates of different specifications can be used. The plate is attached with aluminium curtain wall decorative line, so it should be considered that the center of gravity of the plate overlaps with the hoisting steel wire during hoisting.
