Technical Requirements and Methods of Building Curtain Wall Engineering Seam Processing! -Ruminum Profiles Supplier

The building curtain wall refers to the surrounding of the outer wall of the building's main structure of the building, which mainly plays the function of insulation and heat insulation, covering the wind and rain, controlling noise and decorative buildings. Usually choose metal components or different boards as materials for building curtain walls. Therefore, according to the different building curtain wall materials, the common types include metal curtain walls, glass curtain walls and stone curtain walls. Building curtain walls are widely used in commercial buildings, civilian buildings and industrial buildings. It consists of structural framework and inlaid plates without assuing the main structure load and function of the main body. The effect of insulation, waterproof and noise control. This article mainly discusses the technical requirements and methods in its seam processing.

1. The problems often occur in the building curtain wall structure The building curtain wall is connected to the floor and ceiling. In the decoration design, a horizontal frame will be set to connect the floor ceiling at the curtain wall. It will lead to poor sound insulation and insulation in the building. At the same time, the curtain wall metal frame often appears in the cold bridge phenomenon, which is often said to be exposed. This situation will appear in winter and summer, so how to choose the correct design method, using reasonable seam technology is the key to solving the problem.

2. The problem that the building curtain wall project needs to be paid attention to in the design of the construction curtain wall design is certain. Generally, the inspection and cleaning of the quality and location of the embedded parts, the quality and location of the embedded parts, the welding of the connector, the vertical frame and the horizontal frame The installation and construction, the installation of the fan fan, the installation of the curtain wall glass, the coating of the sealing glue, and the final cleanup process. The impact of the environment is great, and the implementation of sealing adhesive injection in low temperature or rainy days will be affected. For different types of seams, different connections should be selected, and different seam connections and different material types should be selected according to the seams and other types of materials according to the seams.

3. Types of seam design and materials for building curtain walls Choose the seam design of the building curtain wall, which are divided into dense sealing, rubber seal sealing, anti -water discharge seams, anti -noise seams, and anti -shaped seams.

(1) The use of sealing in the seam design of the building curtain wall is the most commonly used is sealing. According to the different requirements of the seal, you can choose different sealing types. Common types of sealing gels include: silicone structure sealing, silicone weather -resistant sealing and fire -resistant sealant, etc. Several seals have their own advantages and cannot be replaced by each other. They can only be selected according to the requirements of the seam position. A. Silicone structural sealing gelsine silicone structure sealing is characterized by strong bonding performance and large strength delay. It is usually used for stress parts related to the safety of the curtain wall. The seams must bear the weight of the glass plate itself, and at the same time, the impact of earthquake and wind load must be assumed. 0.01N, but when considering wind load and earthquake effects, this value must be expanded by 20 times. Considering the effects of loads, expansion and deformation in different cases, we must make more accurate calculations. Different plastic seam calculation methods are different, and the design requirements are different. For example, the connection position between the panel and the glass ribs of the full glass curtain wall, due to the large gap between the whole glass wall panel and the panel, panel and glass ribs, fill the middle of the plate seam of the all glass curtain wall, and then use both sides to meet the structure to satisfy the structure When the requirements are required, the thickness of the gel sewing is greater than 6mm; if the design of the hidden frame and the semi -hidden frame glass curtain wall, the thickness of the gel sewing should be between 6 and 12mm. Under normal circumstances, there will be support or metal safety parts at the lower end of the hidden frame or horizontal semi -hidden frame glass curtain wall to ensure the safety of the building curtain wall. B. Other sealing gels and several other sealing glue, such as silicone weather -resistant sealing, fire -resistant sealant, etc. also have their own characteristics. Silicone weather -resistant glue -resistant ultraviolet and atmospheric changes, aging resistance and can leak rain prevention, and can also avoid the deformation of the panel at the seam. It is often used for the seam of the stone curtain wall panel; Facial fire prevention. In addition, T -base thermal melting seals, dry hanging stone curtain walls, epoxy adhesives, etc. are also common sealant.

(2) The use of rubber sealing strips of rubber sealing strips is also a commonly used connection tool. The rubber strip itself has the advantages of small deformedness, UV resistance and aging resistance. At the same time, it has elasticity. The role of sewing and sealing. Common types of rubber products include Sanyuanye Rubber, Silicon Rubber and chlorine rubber. However, because the quality of rubber sealing strips on the market is not effective, it has been gradually replaced by silicone sealing.

(3) The waterproof design building curtain wall of the seam has the function of covering the wind and rain, so the waterproof design at the joint seam is very important. How to design a reasonable drainage outlet and outlet is the following three types of connection that needs to be valued. The sewing needs to be waterproof design. When the canopy, such as the initial structure of the building and the curtain wall, do a good job of waterproof and drainage, especially when the steel beam of the canopy is directly connected with the building main structure, it is necessary to seal the curtain wall panel. Water inlet. The components of the seams of the bright glass curtain wall and the unit glass curtain wall should be reasonably designed to be reasonably designed to the inserted seams and the opening of the curtain wall, and the principle of rain curtain is used to prevent the penetration of rainwater and the formation of condensed water. If the stone curtain wall or the metal panel curtain wall is used, it needs to be designed to design a drainage.

(4) Anti -noise, anti -corrosion, and anti -forming seam design of the curtain wall component may produce friction noise, which can be designed by the setting of flexible pads or a blank method; different metals or other electronic conductors can be used as a Electric electrodes often form electric puppet corrosion, so setting insulation pads at the metal joints is an effective method for corrosion; at the same time, in order to prevent the impact of the deformation seam of the theme construction, it is required that the curtain wall panel should be designed in accordance with the requirements of the main structure. Don't cross the deformation seam. Finally, different types of seams of the building curtain wall have an important impact on the insulation, heat insulation, waterproof and noise prevention of the building. Therefore, in the decoration design, it is necessary to choose different connection methods according to the requirements of the building and the extent of the external environment to avoid the impact on the curtain wall itself and the main structure.
