The specific height of high-rise exterior walls can be tens or hundreds of meters. The use of extruded boards on the exterior walls of such high-rise buildings can provide better protection for the entire building. For example, the alternating seasons of hot and cold, the rainy season, etc. will have more or less impact on the exterior walls of the building. Below, we mainly explain it in detail from several aspects.
Three basic materials are required for the insulation construction of high-rise exterior walls, namely extruded boards, extruded board bonding mortar, and insulation nails. These three materials can firmly fix the extruded boards on the exterior walls. Before construction, the construction site needs to be cleaned. The purpose of cleaning is to make the entire exterior wall smooth and smooth. For the convex or concave areas, remove and fill them. After the entire wall is cleaned, we can start the installation of the extruded board.
The installation of the extruded board needs to be carried out according to the requirements of the drawings. Some will require the use of galvanized steel supports, and some will require the use of expansion screws, depending on different situations.
Take the construction steel support as an example. The first step is to fix it, that is, to fix the steel support according to the requirements of the drawing. After the fixing is completed, the bonding mortar is used to bond with the extruded board. The thickness of the mortar needs to be greater than 10mm. When the bonding mortar is applied on the extruded board, it can be applied at points. Each point needs to be greater than 100mm directly, and the distance between points is controlled within 200mm. After the application is completed, the extruded board can be attached to the wall.
There are usually two problems involved in the construction of extruded boards. One is that the extruded board is uneven when it is attached, and the other is the density of the expansion screws used to install and fix the extruded board. When the extruded board is uneven, the exterior wall putty can be used for leveling, because a large adjustment has been made when paving the extruded board, and its misalignment will not be too different.
When fixing the extruded board, the expansion screws are usually required to be 4 per square meter. Of course, if the design drawings have specific requirements, the construction work can also be carried out according to the drawings.
The construction of extruded boards requires different process operations based on different sites and construction environments, and cannot be generalized. The above information is for reference only. Please contact us if necessary.
