Some friends in the process of using the electric rolling shutter door found that the surrounding frame and the wall joint appeared water leakage, including the lower corner of the window and the combination of the window of the joint more. How did this happen?
Analysis: electric rolling shutter doors are widely used in residential buildings. If the installation and construction, some details are not done, it is easy to appear water seepage phenomenon.
Solution:
1. Due to the different thermal expansion coefficients of the same wall material as the electric rolling shutter door profile, the capillary cracks are easy to occur at the connection between the frame and the wall under the influence of temperature. In order to prevent water seepage at cracks, Chongqing electric rolling shutter door and window frames should be elastically connected with the wall. During construction, floating ash, mortar particles and other sundries in the connection groove should be removed first, and then sealant should be injected around the connection between the inside and outside of the frame and the wall for sealing. The glue injection should be continuous, not missing, and the bonding should be firm.
2. For the exposed connecting screws, sealant should also be used to bury and seal to prevent water seepage. The doors and windows of the electric roller shutter are not firmly installed, the overall rigidity is poor, and the connection between the electric roller shutter door and window frame and the wall is cracked. When pushing and pulling or opening and closing doors and windows, the frame fan shakes. Large deformation and shaking of the window frame under wind pressure or pushing and pulling by hand.
Defensive measures:
1, electric shutter doors and windows should be according to the door and window hole size, installation height, select the appropriate profile.
2. When installing the electric rolling shutter door and window frame, the connector should be used to make a reliable connection with the wall. The connecting parts shall be made of thin steel plate with a thickness of not less than 1.5mm and shall be treated with anti-corrosion. The connection method generally adopts expansion bolts and needle embedded in the wall.
3. After the electric rolling shutter doors and windows are installed, the door and window frames can be pushed hard for inspection. If shaking or deformation is found, reinforcement treatment should be carried out.
