TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction more specifically, the utility model relates to general sealing type expansion joint protection device. BACKGROUND
[0002] The storage tank cofferdam refers to an annular protective facility arranged around the storage tank, which is usually constructed by cement concrete, steel plate or other materials with good sealing performance, aiming to prevent the leakage material from flowing out of the cofferdam range when the storage tank has a leakage accident, thereby reducing the harm to public safety and environment.
[0003] The concrete structure of the cofferdam is relatively sensitive to temperature change, and thermal expansion and cold contraction may cause stress concentration and cracks in the structure, thereby affecting the overall performance and safety of the cofferdam, so it is necessary to design an expansion joint on the cofferdam at every certain distance.
[0004] However, the current expansion joint has many problems. First, it is difficult to conduct regular inspection on the sealing performance of the expansion joint, and it is difficult to ensure that potential problems can be found and handled in time. Second, the refractory mortar used for filling is prone to sink after being heated, forming a local hollow, thereby damaging the protective plate and affecting the integrity and sealing performance of the expansion joint. In addition, the expansion joint protective plate is usually made of aluminum sheet and fixed by screws. Since aluminum is relatively soft, it is prone to deformation or damage under pressure. Moreover, since most expansion joint protective plates are installed inside the cofferdam, special hot work operation tickets need to be signed for maintenance, which is complicated and costly, further increasing the difficulty of maintenance. Therefore, it needs to be improved and optimized. UTILITY MODEL CONTENTS
