The window wall is the outer wall of the building. It is not load-bearing and hangs like a curtain, so it is also called a hanging wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. The building envelope is composed of a structural frame and inlaid panels, and does not bear the load and effect of the main structure.

What needs to be done on the maintenance part of the window wall?

An important part of the window wall is glass, and glass is a vulnerable part, so management and protection are very important.

Extensive ventilation is necessary in the place of preservation. Especially in the high temperature and cycle temperature cycle, more attention should be paid. If conditions do not allow them to be stored indoors, they should be covered with a tarpaulin or plastic to protect from wind and rain and inflow of water, and the cover should be opened periodically to check for condensation.

The glass of the window wall must be covered with an opaque protective cover, and must not be stored directly under the sun. Stacks of various types of glass should be placed upright at an angle of 5°-7° from the vertical and leaned against a firm straight wall. The top and bottom edges of all glass should be linoleum and separated with protective cardboard or other linoleum. If the glass is laid flat, the surface must be covered with linoleum to prevent dust, grit glass flakes or other contaminants.

How can window walls be regularly inspected?

(1) During the warranty period, the supplier will organize regular inspections and return visits for the window wall, and find hidden quality problems and eliminate them in time.

(2) Check the glue strip and glue injection of the window wall at any time, and replace or repair it in time if it is found to be falling off or damaged. Note that when repairing the adhesive strip of the window wall, it must wait until it is completely cured (24h) before proceeding. When repairing, the damage needs to be cleaned up and larger than 2/3 of the length.

(3) Regularly use the window cleaning machine for cleaning.

(4) Surface repair: repair paint for local damage or scratches.

How to choose the right window wall according to the design requirements?

see design requirements

1) The design drawings of the window wall should be complete and detailed, and the expression should be standardized. Description of construction drawings and construction requirements, large sample drawings of nodes, calculation of anchoring nodes of embedded parts, calculation of stress and deformation of curtain wall keel frame under vertical load and horizontal load, lightning protection, fire prevention, and drainage measures must be complete.

2) The window wall design should take measures to prevent rainwater leakage. The cross-sectional form of the columns and beams of the glass curtain wall should be designed according to the principle of equal pressure. The condensed water part should be provided with a condensed water discharge pipe, and the drain holes should be drilled in strict accordance with the regulations during the production of the components. The sealing material of the opening part should be made of neoprene or silicone rubber.

3) Insulation gaskets (general thickness lmm) or other anti-corrosion measures should be set at the contact of different metal materials of the window wall, and the size of the insulating sheet should not be less than the contact area to ensure that the aluminum alloy column is in direct contact with different steel connectors, and the column A flexible gasket should be provided at the contact with the beam.
