Regarding the construction strategy of armored expansion joints, this topic has been mentioned again recently, and I will take this opportunity to sort out an article related to this for your reference.
Armored expansion joint is a sealing device commonly used in large buildings, bridges and highways to compensate for structural deformation, isolate noise and vibration, and prevent damage to buildings caused by external factors such as wind and rain. The following will be an in-depth analysis of the construction strategy of armored expansion joints, and introduce the methods of its installation and maintenance.
1. Construction strategy of armored expansion joints.
1. Design scheme: According to the specific engineering requirements and structural characteristics, determine the type, size and location of the expansion joint, and formulate the corresponding design scheme.
2.Construction preparation: including pre-treatment, cleaning and repair of structural surfaces to ensure that the construction area is flat and free of debris. At the same time, inspect the relevant equipment and tools to ensure that they are in good condition.
3.Installation of armored expansion joints: According to the design drawings and engineering requirements, the armored expansion joints are fixed between the structures of the building. Attention should be paid to the tension and pressure of the elastomeric material during installation to ensure the tightness and stability of the expansion joint.
4.Sealing treatment: The expansion joint is sealed with professional sealing materials to ensure that it can withstand external factors such as wind, rain and temperature changes.
5.Testing and commissioning: After the installation is completed, test and debug are carried out to check whether the normal operation and sealing performance of the expansion joint meet the requirements.
6.Non-repetitive construction: After installation, ensure that there is no more construction activity in the work area around the expansion joint to avoid affecting the expansion joint.
2. Installation and maintenance of armored expansion joints.
1. Precautions for installation:
Installation is carried out in strict accordance with the design plan and construction requirements to avoid errors and missed work
Check whether the materials and fittings of the expansion joint meet the requirements to ensure their quality and durability;
During installation, avoid hammering or heavy collision to avoid damage to the expansion joint;
Pay attention to the tension and pressure of the elastic material to ensure the normal operation of the expansion joint.
2.Maintenance Method:
Regularly check the sealing performance and functional status of the expansion joint, and repair or replace it in time if there is damage or aging
Clean the surface and surrounding area of the expansion joints of the armor to avoid the accumulation of dust and debris;
Protection against chemical corrosion and mechanical wear and tear with suitable protective measures;
Under special conditions, such as high or low temperature environments, corresponding measures need to be taken to protect the performance of expansion joints.
The correct installation and effective maintenance of armored expansion joints play an important role in ensuring the safety and function of the building. During the construction process, it is necessary to operate in strict accordance with the design requirements and construction specifications, and at the same time reasonably maintain the good condition of the expansion joint to ensure its long-term stable operation.
