What needs to be done before the installation of flexible waterproof casing?
The rubber sealing ring of flexible waterproof casing should be inspected before use, there should be no cracks, crazing, misalignment, misalignment, flying edge, etc. The surface in contact with the rubber ring should be clean, the valve rubber ring and waterproof casing on the pipe through the wall should be straight and not deformed, and set up the necessary pipe supports and piers near the wall of the structure (building) to ensure the uniformity of the circumferential gap when installing the pipe through the wall, the casing flange and the axis of the flange gland concentric, the sealing performance and service life of the rubber sealing ring, bolts and fasteners should be set up in a convenient manual operation place. At the side, bolts should be tightened evenly and symmetrically. Due to other applications, flexible waterproof casing can improve the safety performance of engineering construction. Therefore, flexible waterproof casing has long been an indispensable raw material in construction projects. The application of flexible waterproof casing in construction projects has been widely known. Briefly introduced the installation and processing process of flexible waterproof casing. Flexible waterproof casing installation and processing considerations:
1, pre-buried parts before laying, please carefully check whether the pre-buried parts of each welding support is solid and reliable. Check whether all the pre-buried parts are deformed or rusted, and only the welding is solid and reliable. Pre-embedded parts can only be installed after the rust prevention problem is solved.
2、During the construction of the construction project, the pre-buried parts should be installed according to the engineering drawings. Pre-embedded parts in the pre-embedded parts must be installed firmly, if necessary, welding equipment should be used to accurately position the parts to ensure that the pre-embedded parts are installed correctly.
3, remove the flexible waterproof casing of the marble curtain wall, align the pre-buried parts with the ends of the parting joints of the curtain wall. In addition, according to the size of the beam, the template on the side of the beam should be resealed.
