Key points in the construction and maintenance of deformation joints.
Deformation joints play an important role in construction projects, and their proper construction and maintenance are essential to ensure the structural stability and durability of buildings. This article will be the key points of deformation joint construction and maintenance.
1. Preparation before construction.
Adequate preparation must be carried out before the construction of the deformation joint is carried out. First, you need to carefully study the architectural design drawings to determine the location, type, and size of the deformation joint. At the same time, it is necessary to conduct a detailed survey of the construction site to understand the foundation condition, surrounding environment and other factors in order to formulate a reasonable construction plan.
Second, the construction process.
1.Material selection: Choose deformation joint materials with reliable quality and excellent performance, such as waterproof membranes, sealing strips, metal covers, etc. Ensure that the materials comply with the relevant standards and design requirements.
2.Base treatment: Before construction, the base layer of the deformation joint should be cleaned and treated to ensure that the base layer is smooth, dry, free of cracks and debris.
3.Install the sealing strip: Install the sealing strip correctly on both sides of the deformation joint to ensure that the sealing strip fits closely with the base layer and effectively prevents water and air penetration.
4.Fixing the metal cover: According to the design requirements, use the appropriate fixing method to install the metal cover on the deformation joint to ensure that the cover plate is smooth and firm.
5.Waterproof treatment: Carry out waterproof treatment on the deformation joint, such as painting waterproof coating, laying waterproof membrane, etc., to prevent moisture from entering the deformation joint.
6.Inspection and testing: During the construction process, inspection and testing should be carried out in time to ensure that the construction quality of the deformation joint meets the requirements.
3. Maintenance and maintenance.
1.Regular inspection: Regularly inspect the deformation joints to observe whether there are cracks, water seepage, aging of the sealing strip and other problems, and repair and replace them in time.
2.Cleaning & Cleaning: Keep the deformation joints clean, remove debris and dirt, and avoid blockages and affect normal function.
3.Waterproofing: Regularly inspect and maintain the waterproofing measures of the deformation joint, and repair or reconstruct it in time if the waterproof layer is found to be damaged or invalid.
4.Structural monitoring: For important buildings, structural monitoring can be carried out, structural changes around deformation joints can be detected in time, and corresponding measures can be taken for maintenance and reinforcement.
The construction and maintenance quality of deformation joints is directly related to the service life and safety of the building. Therefore, in the construction process, it is necessary to operate in strict accordance with the norms and standards, and at the same time pay attention to the daily maintenance and maintenance work. Only in this way can we ensure that the deformation joint plays its due role and provides a guarantee for the stability and safety of the building.
