Curtain wall for old town

The urban renewal project is different from the traditional reconstruction project. This reconstruction includes two parts: demolition and installation, and it is necessary to “repair the old as the old and integrate the old and the new”. The surrounding area of the curtain wall construction area is downtown or residential area. The project is huge, the construction site is narrow, and the environment is strict. How to safely and efficiently complete the organic renewal of the project? This is the primary problem facing the architect and the opportunity for the curtain wall to reflect the professional value.

First, the old facades of buildings in the old town need to be demolished. In order to ensure safety, according to the characteristics of different parts of the building, the combination of ground and cantilever scaffolding, the outer layer of the laying of steel plate protective net to form a hard closed, if necessary, set up horizontal steel plate for protection: the removal of water and dust, low noise equipment, to avoid the entrance of large construction machinery. In this way, it not only ensures construction safety, but also reduces noise and dust pollution to the greatest extent.
Secondly, in order to retain the characteristic of well-arranged historic blocks, the curtain wall adopts rich systems and materials, as well as various irregular plates and profiles, etc., and there are a lot of closing and connecting between materials and old buildings, which puts forward high requirements on the precision of processing and construction technology. Precision in order to restore the keel and the plate size, project department through 3 d laser scanner, scanning the appearance of the building complex, and collection point information space, compared with BIM model, integration the facade features, complete curtain wall connection mode, a clear expression of curtain wall node connecting relation between modern curtain wall design and curtain wall, in order to verify the rationality of the design of curtain wall, On this basis, the curtain wall design is further optimized, adhering to the concept of “heavy processing light installation”, so that the complex node design is processed in the factory, so as to achieve the efficient and perfect architectural intention.
In addition, due to the variety of curtain wall, and each area is small, in the construction process, to achieve accurate and fast installation. Especially when the keel is installed, on the basis of making full use of the original curtain wall glazing components, stainless steel and other high anticorrosive material components are used as far as possible, and the bolt connection method is selected from the perspective of fire prevention. It is this combination of old and new that makes the fireworks of the old street continue.
