Description

Technical Field

[0001] This utility model relates to the field of prefabricated flooring technology, and in particular to a wooden prefabricated floor. Background Technology

[0002] In today's building decoration industry, with the improvement of people's living standards and the enhancement of environmental awareness, the requirements for indoor floor decoration materials are becoming increasingly stringent. Wooden flooring, with its natural and beautiful texture, warm and comfortable touch, and good environmental performance, has become the first choice for many consumers. At the same time, the concept of prefabricated construction has rapidly emerged and been widely used globally due to its advantages of high efficiency, environmental protection, and controllable quality. Wooden prefabricated flooring has emerged to meet this need, integrating the traditional charm of wooden flooring with the advanced concept of prefabricated construction. In terms of environmental protection, with the increasing awareness of global forest resource protection and sustainable development becoming the theme of the times, wooden prefabricated flooring tends to use fast-growing timber, engineered wood products made from reprocessed timber scraps, and FSC-certified sustainable timber, effectively reducing dependence on precious natural timber. Furthermore, the prefabricated production model reduces the generation of on-site construction waste and lowers energy consumption and carbon emissions during the decoration process.

[0003] A search revealed Chinese Patent Publication No. CN214981779U, which discloses a novel type of wooden flooring. The flooring, from top to bottom, comprises a surface layer, a first strength layer, and a substrate layer. These layers are bonded together. The first strength layer is made of high-density fiberboard and has a thickness of 0.5–3.0 mm. This design effectively ensures a relatively smooth decorative surface during mass production, resulting in a relatively high yield and relatively low manufacturing cost. However, during installation, the aforementioned wooden flooring… Traditional wood flooring involves a complex process, from cleaning and leveling the subfloor to assembling and fixing each plank. This requires a significant amount of manpower, time, and effort. Furthermore, the installation process involves the use of large amounts of glue and nails, which can easily pollute the indoor environment. Additionally, the flooring may warp or loosen later due to glue aging or nail loosening. Moreover, traditional wood flooring becomes much more difficult to install when faced with complex subfloor conditions, such as uneven surfaces or areas with pipework. This can even require large-scale renovations of the subfloor, further extending the construction period and increasing costs. Utility Model Content
