Assembling curtain wall system
![Page 4: A Self-Assembling Curtain Wall System](https://reader034.vdocuments.mx/reader034/viewer/2022042614/55555180b4c9052b208b4cc7/html5/thumbnails/4.jpg)
Problem
Problems by the assembling of curtain wall elements
• Assembling conditions are unsafe and not labor friendly
• High buildings need a tower crane
• Climate conditions delete the work
• A lack of skilled labor
• The life cycle of curtain wall system is about 10 years

Conclusions of the earlier study
Design Problem
• Safe construction site for assembly workers.
• Curtain wall is appropriate for high-rise constructions involving a steel load-bearing construction.
• The curtain walls are only made of aluminum and glass.
• The curtain wall is equipped for the assembly and disassembly processes. Its components can also be used for user functions (particularly systems) of the façade element.
• Only one remote operator is necessary for the (dis)assembly process.
• Mini- and micro-robot devices are used.

Reflection
Comments by the industry
• No influences of climate by guiding system.
• Doubt if market is interested for such façade facilities.
• Integration of the electric drive and the positioning very interesting.
• Reliability of the guidance system and water and wind sealing is weak.
• Easy for renewal is interesting.

Reflection
Discussion
• Most of the requirements are full filled.
• Not the whole façade is self assembly.
• Same parts have not still been tested, such as wind and water sealing, gear transmission and guide rails.
• The cost of the driving motor is relatively high and has to much power output fur the functions as ventilation and sunscreens. A solution would be to use a replicable motor.

Reflection
Conclusions
• The concept (dis)assembly work is safer and more labour-friendly.
• Weather conditions have less influence on the progress of the construction work.
• There is drive for ventilation and sunscreens.

Reflection
Coming research
• Testing the water and wind sealing between the elements.
• Testing the guiding of the elements
• More research to a suitable drive.
