[0002] Against the backdrop of the rapid development of the construction industry, precast floor slabs, as a more environmentally friendly, energy-saving, and efficient building structural material, hold significant development and application prospects in the construction sector. Precast floor slabs, manufactured using prefabrication methods, offer numerous advantages, including consistent product quality, design flexibility, low initial costs, a long construction cycle, high construction efficiency, a long service life, and strong environmental adaptability. With increasing market demand and the proliferation of public projects, precast floor slabs will be increasingly widely used and promoted.

[0003] Prefabricated floor slabs are widely used in the renovation and repair of old buildings. However, existing prefabricated houses cannot achieve effective waterproofing and insulation, resulting in buildings with prefabricated floor slabs being very hot in summer and very cold in winter, seriously affecting the comfort of living. In addition, when adding insulation and waterproofing to prefabricated floor slabs, structural, space, connection and other issues need to be considered. In addition, during the renovation construction of old buildings, the internal layout and space should not be changed as much as possible, and the livability should be maximized while ensuring the safety of the building. As a result, the use of prefabricated floor slabs to repair old buildings cannot achieve a level of satisfaction for residents in terms of waterproofing, insulation, structural connection and other aspects.
