[China Glass Network] Glass installation in place
Glass hoisting
The installation of large glass is a very detailed and accurate overall tissue construction. Before the construction, it is necessary to check the personnel of each station in place, whether the various tools are complete and normal, and whether the safety measures are reliable. Spider-man tools and parts must be tooled and placed reliably to prevent objects from falling or injuring the glass. The glass can be hoisted after all inspections have been completed.
(1) Check the quality of the glass again, paying particular attention to whether the glass has cracks or chipping, and whether the position of the copper clip is correct. Dry the surface of the glass with a dry cloth and mark the center of the glass with a marker.
(2) Install the electric suction cup machine. The electric suction cup machine must be positioned, symmetrical, and slightly above the center of the glass, so that the glass after lifting will not be deflected left and right, and will not rotate.
(3) Try lifting. The electric suction cup machine must be positioned, and then the glass should be lifted first, and the glass should be lifted 2-3 cm to check whether each suction cup is firmly adsorbed.
(4) Install the manual suction cup, cable pull rope and side protection rubber sleeve in the appropriate position of the glass. The manual suction cup on the glass allows the workers working at different heights to assist the glass in position when the glass is in place. The cable is used to control the glass swing when the glass is hoisted, rotated, and seated, preventing the glass from being out of control due to wind and crane rotation.
(5) Paste the low-foaming spacer strip on the inside of the upper and lower frames where the glass is to be installed. The width of the strip is the same as the width of the designed seam. Allow sufficient thickness of glue to be applied when sticking the strip.
2. Glass is in place
(1) After the crane moves the glass closer to the in-position position, the driver should listen to the commander's command to operate the hydraulic micro-motion lever to make the glass alignment position close.
(2) The upper level workers must grasp the glass to prevent the glass from colliding with the steel frame during lifting and shifting. After the workers at the lower level can grasp the manual suction cup, the protective rubber sleeve on the side of the joint can be removed. Use the manual reverse chain of the hanging electric suction cup to slowly lift the glass so that the lower end of the glass is slightly beyond the lower border. At this point, the lower worker should gently pull the glass into the slot and block it with wood to prevent collision with adjacent glass. In addition, some workers use the wooden board to rely on the lower end of the glass to ensure that the glass can be placed in the slot of the bottom frame when the glass is slowly lowered, and the lower end of the glass should be prevented from colliding with the metal slot.
(3) Glass positioning. Install the glass hanger clamp and the hanger bolts should be placed in the position marked on the steel beam. Adjust the rod bolts repeatedly to lift and properly position the glass. After the front glass is in place, check the verticality of the side of the glass. The glass that is in place afterwards should only check whether the gap between the glass and the glass that is in place is equal and meet the design requirements.
(4) After installing the upper outer metal clip, fill the foam round strip in the outer notch of the upper and lower frames to make the installed glass temporarily fixed.
