Technical Field
[0001] The utility model relates to the technical field of expansion joint protection, in particular to an expansion joint protection device. Background Art
[0002] Expansion joint guards are devices used to prevent damage or safety hazards that may occur at expansion joints in structures such as buildings or bridges. Expansion joints are usually gaps set to accommodate the natural deformation of the structure caused by temperature changes, earthquakes and other factors. These devices play a vital role in green building or ultra-low energy design. In addition to traditional coverings, fillers or sealants, expansion joint guards can also be made of renewable or highly sustainable materials to reduce the impact on the environment and fit in with the overall sustainability concept of the building. This innovative material can not only effectively fill the expansion joints and prevent the ingress of substances such as water and dust, but also reduce energy consumption and improve the energy efficiency performance of the building. Through reasonable design and material selection, these devices can not only ensure the stability and safety of the structure, but also provide strong support for the green certification of the building, extend the service life of the structure, and make a positive contribution to the sustainable development of the overall building environment.
[0003] At present, most of the main body construction of buildings adopts traditional protection methods, and usually only simple protection is done on the expansion joints of the floor slabs. This approach has a series of problems: first, this method requires a large amount of materials to seal the bottom of the expansion joint, which is not only costly but also has a long construction period; second, although traditional steel pipe protection can play a certain protective role, its effect is limited and cannot completely prevent the falling of debris, which can easily cause construction workers to step on empty space and fall; in addition, since the side protection effect is not obvious, small stones and other debris on the upper layer may fall to the lower layer, causing safety hazards; at the same time, rain and snow can easily penetrate into the main body through the expansion joint, affecting the work efficiency and safety of the construction workers, and it is impossible to ensure that the rock wool is not soaked by rain and snow or invaded by moisture, and it is impossible to ensure the air tightness of the expansion joint and other related requirements.
[0004] In order to solve these problems, we need to adopt more advanced and effective expansion joint protection technology. Based on this, we propose an expansion joint protection device. Utility Model Content
