Unit curtain wall is by two adjacent components in the main curtain wall structure of the installation of the joint, so it in the structure and connection processing and unit type curtain wall has a significant difference.
In unit curtain wall fittings, installed on the main structure to install 1 unit (overall height or 8-10 floors) 1 to install in place, all with the installation precision of fittings to ensure the quality of the installation of the unit curtain wall.
The unit components of the unitary curtain wall have been assembled in the factory with panels (glass, aluminum, granite SLATE), which are connected to the main structure only on one side of the interior, so there must be room for operation on the inside. In this way, it is very difficult to install the building with the floor and column outside flush.
The connecting point support curtain wall is arranged on the solid wall. Because to make all the connectors of an installation unit (full height or 8-10 floors) with three-way accuracy adjusted in place once, it is necessary to use multiple hanging blue for safety adjustment. At this time, the time of installing adjusting connectors may be 3-5 times that of lifting fixed unit components. And because there is no operating space inside the component, the connector is required to achieve the accuracy required by the position in all three directions, and the connection and connection on the unit component should be fully matched in order to be successfully placed at a time when lifting. If the fitting tolerances of the connecting pieces on the modern curtain wall and the connecting members on the unit assembly are slightly larger, they will not be installed smoothly.
In addition to the installation accuracy of the connector installed on the main structure to ensure the installation quality of the unit component, but also in the process of lifting and fixing has a certain adjustment possible, that is to say, the connector should have three-dimensional movement and 3 direction corner. It is carried out in two stages, that is, the adjustment of connecting pieces when they are installed on the main structure and the fine adjustment in the process of lifting. For the surface roughness, in order to ensure the unitised curtain wall fittings installed on the main structure to make the Z direction at a time when fully in place, namely fixed fittings installation cannot have Z to the displacement and Angle, X, Y, the initial adjustment in place, and in the design of fittings, to make them during the installation process, in the X, Y, to adjust the displacement and Angle can trace, so that the hoisting is who can smooth implementation.
