The basketball court has a total length of 32 meters and a width of 19 meters. The line size is 28 meters by 15 meters, and the total area is 608 square meters. The foundation is paved with cement concrete, and the surface layer is laid with 3 mm thick silicon PU.
Material Description:
Silicon PU golf course material is a golf course material with multi-functionality and construction advantages. By modifying technologies such as silicone elastic particles, PU materials can be directly applied to concrete floors. There is no cracking or bubbling. It also has the excellent properties of conventional PU and acrylic.
Construction plan
1. Elastic layer:
Before the construction of the elastic layer, it should be carefully checked to confirm that the elastic layer can be applied after the foundation treatment. The elastic layer is a one-component material. Only the thinner should be used to adjust the suitable construction consistency. The scraping plate is applied to the base surface, and the thickness of each coating is applied. Do not exceed 2.Omm, and each drying time interval should be dried until the desired thickness is applied. After the elastic layer is dried, the surface flatness is tested by the accumulated water method, and the water is repaired and leveled.
2. Strengthening layer:
The reinforcing layer is a one-component material, and the construction method is consistent with the elastic layer. If the reinforcement layer design is smaller than the book (less than 1mm), the tooth scraping and scraping is difficult to level, and the squeegee can be used for multiple coating. It is necessary to ensure that the surface is smooth and smooth after the coating, if any debris is mixed or scraped during the construction process. If there is unevenness, it needs to be smoothed before the surface layer construction can be carried out.
3, the surface layer:
The surface layer is a two-component water-based material, and the two components must be thoroughly stirred uniformly according to the prescribed ratio. The water-diluted construction consistency is sprayed on the reinforcing layer by a special spray gun. It is necessary to add special sand for surface roughening. The lowest temperature below 5 °C is not suitable for construction, and it is kept for 10 hours without water after construction.
4, scribing
According to the standard size measurement, mark the position of the boundary, use the textured paper on both sides of the boundary line to paste on the field, paint with a special line paint on the textured paper, and peel off the textured paper after the surface is dry. After the site is laid, it needs to be kept for more than 3 days before it is put into use.
Effect:
The double-layer structure is considered from the perspective of professional sports. According to the technical characteristics of the ball sports, the athletes can start easily, move quickly, and absorb the damaging shock generated during the movement. Superior weather resistance, no fading, chalking, hardening, softening, etc. due to environmental changes such as ultraviolet rays, ozone, rain and high and low temperature climate, and can maintain its vivid color for a long time. Under normal circumstances, six years without discoloration, superior wear resistance. It can ensure the appearance and structure characteristics of the structure to be stable and stable for a long time, and has good wear resistance, which can meet the needs of long-term high frequency of use. The anti-fouling strong surface layer is tough and dense, and it is not easy to be scraped by the sole or other hard objects. It can keep the stadium clean and new for a long time. An unattended course is also suitable for use.
