Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of a wear-resistant and non-slip integrally suspended assembled shock-absorbing sports floor. Background Art

[0002] With the advent of the era of "national sports" for sports and fitness, the installation and use of wooden sports floors in sports venues has become more and more common. The overall suspended assembled sports floor is currently a more advanced floor installation construction technology. It is a construction process that separates the base of the sports floor from the building floor. The elastic rubber pad is used as the bottom structural layer. The elastic rubber pad, the wooden keel treated with special technology, and the multi-layer board are fixed with reinforced nails to form a suspended overall base structure. It subverts the construction process of fixing the traditional wooden keel system with rivets or expansion bolts on the building ground, and changes the characteristics of poor shock absorption, elasticity, and sports performance. The surface layer uses finished panels that have been completed in the production workshop through finger jointing and ultraviolet light curing paint technology, and is assembled with tongue and groove, reducing the traditional surface grinding, paint spraying and other construction processes, as well as the problem of poor operation. The suspended structure has the advantages of perfect sports performance, convenient construction, simple and convenient operation, and no process interruption. It is particularly suitable for the paving of new venues and the renovation of old venues. At the same time, it is not affected by climatic conditions and temperature, and can adapt to completing construction in a shorter time.

[0003] The suspended assembled floor adopts mature high-strength polypropylene environmentally friendly materials, which effectively solves the problem of thermal expansion and contraction of the floor while also having stable surface friction. Anti-UV additives are added to each piece of floor to ensure that the floor does not fade under long-term sunlight exposure. The suspended structural design plus the sturdy reinforced support foot structure create an excellent vertical shock absorption effect. The non-slip surface can effectively prevent sports injuries. Good ball rebound performance and ball speed ensure the excellent sports performance of the floor. It can be used to pave ideal high-performance basketball courts, tennis courts, five-a-side football fields, roller skating courts, table tennis courts, as well as volleyball, badminton and other multi-functional courts.

[0004] The overall suspended assembled solid wood sports floor adopts a production process that mainly adopts assembly line production in the production workshop and supplemented by on-site assembly. It changes the various uncertain factors affected by external construction conditions and working environment, and realizes the superiority and controllability of construction quality and construction progress. Compared with traditional fixed keel wood floors, it reduces many processes in on-site construction, and vigorously adapts to the requirements of factory processing and on-site assembly and installation advocated by the country. It not only embodies professionalism, environmental protection and safety, but also embodies the four savings and one environmental protection in the construction industry, and has been rapidly developed and applied.

[0041] The beneficial effects of the wear-resistant and non-slip integral suspended assembled shock-absorbing sports floor construction method of the present invention are:

[0042] As the most advanced sports floor installation and construction technology, the overall suspended assembly structure is a construction process that separates the base of the sports floor from the building floor. The elastic rubber pad is used as the bottom structural layer. By fixing the elastic rubber pad, the wooden keel treated with special technology, the multi-layer board, etc. with reinforced nails, a suspended overall base structure is formed, which subverts the traditional wooden keel system and the building ground with rivets or expansion bolts. The construction process has changed the characteristics of poor shock absorption, elasticity and sports performance; the panel layer uses the finished panel completed by the finger joint process and ultraviolet light curing paint process in the production workshop, and is assembled by combining the tongue and groove structure with U-shaped nails, reducing the traditional surface grinding, paint spraying and other construction processes and the difficulty of not being able to cross-operate; the suspended structure has the advantages of perfect sports performance, convenient construction, simple and convenient operation, no process interval, etc., which is particularly suitable for the paving of new venues with short construction period and fast progress requirements and the renovation of old venues. At the same time, it is not affected by climatic conditions and temperature, and can be more adapted to the application of projects completed in a short time, which can fully reflect the good effects of energy saving and environmental protection.

[0043] The overall suspended assembled solid wood sports floor adopts a unique overall suspended structure, which has no connection with the base of the venue, forming a unique load-bearing base of the overall suspended structure. It scientifically utilizes the principle of wood structural fibers to resist and absorb energy from the outside world, without any damage to the floor structure. At the same time, it ensures the overall elasticity of the sports floor. The elastic rubber pad serves as the bottom structural layer. The appearance and use of this structural layer not only makes the solid wood sports floor more practical, but also provides better shock absorption for the suspension structure of the entire sports floor; it provides higher security and safety factor for athletes' sports, and fully reflects the humanistic and scientific construction technology concept.

[0044] The panel of the overall suspended assembled solid wood sports floor is an important component of the sports floor. The raw materials are Northeast maple with moderate hardness, micro-deformation and long fiber structure. The finger-joining process is used in the production workshop to solve the fundamental problem of bending and deformation of the solid wood panel due to different environmental humidity. The surface board is subjected to the ultraviolet light-curing paint process to make the paint film form a three-dimensional structure with high hardness and good wear resistance. The anti-slip and wear resistance are three to five times that of on-site spray paint. The construction process reduces on-site grinding and paint spraying, shortens the overall construction period by about one-fifth, greatly reduces construction costs, and achieves green, environmental protection and energy saving.

[0045] It reduces the labor intensity of workers, improves work efficiency, and reduces the difficulty of operation. It improves the overall quality and progress of the project, saves materials, labor, and construction period. Compared with the traditional sports floor installation method, it can avoid the damage to the main structure caused by rivets or expansion bolts, extend the service life and maintenance cycle, and reduce the comprehensive cost by 10-20%.

[0046] The present invention enables the sports wooden floor to have better load-bearing performance, high shock absorption performance, and anti-deformation performance, thereby improving the overall sports performance of the sports floor. At the same time, the sports floor is developed in a more professional, environmentally friendly, and safer direction. It is economical, practical, and beautiful, and has good application and promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS
