Analysis and Prevention Measures for the Cause of the Curtain Wall-WJW Aluminum Supplier Aluminum

Analysis of the cause of the water seepage of the curtain wall 1. The curtain wall design (1) Important force curtain wall component aluminum profile breaking pillar does not set 20mm telescopic joints according to standards, aluminum profile thermal expansion and contraction, and stress caused by the tightening deformation of the main structure will crack the glass glass, producing water seepage scene. (2) During the design of the curtain wall design, the curtain seal with a large scalability is not adopted, and the necessary calculations are not performed. For example, the curtain of the curtain wall of the curtain wall is 25%of the displacement, which is 2 times that of individual seals. You must calculate the size of the plastic position according to this data disk. Otherwise Or roll up, lose waterproof function. (3) The curtain wall opening window waterproof seal is effective or the number of sealing layers is insufficient (individual requests two to three seals), which causes the rainwater to flow along the curtain wall, directly enter the opening window, showing upside -down water, showing inverted water water, showing upside -down water. (4) When the curtain wall and the construction objects are jointly closed, they do not cooperate and cooperate with the civil engineering units. Instead, they will be constructed, which will lead to the water seepage channel. Especially the curtain of the curtain between the top of the curtain wall and the daughter wall is not strong, and the closure is not strict, such as the screwhole, the top coat of the top, the glue or the glue is not thoughtful, and the missing. 2 curtain wall aluminum profile (1) The nominal processing of the curtain wall aluminum profile is not in line with national standards. The nominal coating has not strong adhesion, and the oxide film is too thin or too thick (the thickness of the anode oxide film should not be lower than the AA15), resulting in sealing sealing Adhesive. The building curtain wall consists of a supporting structure system and panel. It can have a certain displacement capacity compared to the main structure, and the decorative structure or decorative structure of the building is used regardless of the main structure of the main structure. (2) The important force component of the curtain wall is insufficient and the stiffness is not enough. The wall thickness of the section of the section of the section is less than 3mm. Under the standard value of the wind load, the absolute deflection is greater than L/180 or the absolute deflection is greater than greater than the absolute deflection greater than that 20mm, the curtain wall is major deformation, showing shift and leakage of rainwater. (3) Do not adopt high -quality high -precision level aluminum profiles (of which the curtain wall breaks should be adopted by high -precision levels), aluminum profiles are failed. , Verticality cannot reach the request. 3. Curtain wall sealing (1) For the cost of frugality, take individual sealing glue without using weather -resistant silicone sealing for outdoor mitigation. On the curtain wall through the sunlight ultraviolet rays, the rubber seam is too early and aged, resulting in the split sewing of the rubber seam. (2) The effective utilization period of the curtain structure of the curtain wall structure of silicone, the weather -resistant silicone seal of the curtain wall, and the valid utilization period of the scene of the curtain wall, and the expiration of the gel. If the doors and windows and curtain walls have a panel and support structure system (supporting device and support system), it can have a certain displacement ability or a certain deformation capability compared to the main structure of the main structure. (3) Do not perform the compatibility experiment of the contact data of Silicone sealing in the curtain wall structure according to the standard. At the same time affect the sealing effect. 4. curtain wall glass (1) The strength of the curtain wall glass does not perform calculation, the capacity of the glass is not enough, cracking and crushing under the heavy rain of typhoons, resulting in water inlet. (2) The curtain wall glass does not make thermal stress test. The large -scale curtain wall glass receives sunshine, which exceeds its allowable stress, causing heat break. (3) The glass size of the curtain wall exceeds the standard. When the amount of two glass force embedded and the gaps are not in line with the design request, when the device is installed on the light frame glass curtain wall; the glass is not enough in depth, the width of the gel sewing cannot reach the request, the glass does not reach the request, the glass does not reach the request. Easily breaks from the edge; the glass is too large, then the slot is embedded in the position too deep, and the glass is easily squeezed by the heating and expansion. If the doors and windows and curtain walls have a panel and support structure system (supporting device and support system), it can have a certain displacement ability or a certain deformation capability compared to the main structure of the main structure. When the glass is installed on the hidden frame glass curtain wall, the width of the rubber seam is uneven, and it is difficult to hold the quality of the glue. Standard delineation, the width of the hidden frame glass curtain wall glass sewing should not be less than 15mm, so as to ensure the seam gap to satisfy the request of a layer shift due to earthquakes and temperature changes. The method of preventing and controlling glass curtain wall seepage is: 1. First of all, first consider the waterproof design structure of the curtain wall, use the principle of pressure, and set the puzzle and the pores of special pressure on the curtain -type aluminum material. This is an active waterproof method 2. On the curtain wall aluminum aluminum aluminum aluminum The small water holes flowing to outdoors are opened on the profile, and the water collections that enter the inside of the curtain wall through the small gaps are collected and discharged from the curtain wall. Pipeline, this is another solid waterproof method 4. Choose high -quality structural silicone sealant, weather -resistant silicone sealant, wall gel, and strengthen exams to avoid expired utilization. 5. Pay attention to the use environment of secret seals.
