400m standard plastic track data calculation method on how to calculate each point 400 meters dash plastic track, how to design a fixed point, need some basic data. We set the standard in accordance with the IAAF Track and Field Facilities Standards Manual sports track data: perimeter 400 meters, where the bend radius should be 36.5 meters, straight to avoid the blinding effect of low sun position along the north-south direction. The curve should be eight runway, each 1.22 m wide runway, the plastic runway, there are 10 straight runway. The inside of the runway safety area of ??not less than one meter, at best 1 meter outer security zone, starting area at least 3 meters, at least 17 meters sprint buffer segment. Shall not exceed the maximum inclination of the runway about 1: 1000, Lanzhou plastic runway, downward gradient in the direction of running shall not exceed 1: 1000, the runway is semi-circular curve, and the innermost radius of 36 meters, each 1.2 m wide runway, the existing eight runway. Since the known standard runway length of 400 meters, it is the length of the innermost track, and know the innermost radius of 36 meters, so you just need to find the innermost corners of the runway perimeter and two semicircles and then with 400 meters of the perimeter and minus two corners, long straights get. Silicon pu Stadium 400-3.14 × 36 × 2≈174 ÷ 2 = 87m, Ningxia plastic runway, the fourth full length of the runway and obtained from the two straights on the fourth lap of the two semi-circular curve and plus front already know the length of the straight side is: 87, so the first full length of the runway is 4: 87 × 2 + 2 × 3.14 × (36 + 1.2 × 3) ≈423m. High-quality PVC plastic floor: Hospital Expansion in a landscape hospital lobby, waiting area is crowded areas bear the brunt of security, noise, vibration, non-slip PVC flooring naturally become the ideal choice. And PVC floor maintenance is simple and ordinary neutral detergent (PH value 7--10) that is able to remove stains, easy to clean surface can ensure always clean as new, save a lot of manpower and material resources. Xi'an runway using environmentally friendly raw material production of PVC floor, the ground has a rich mosaic pattern, a good combination of architectural forms hospitals, creating a comfortable, relaxed clinic environment, show a modern hospital people-centered medical spirit. Also it comes with colorful spotless hospital, people mind will emerge out of a single white screen. However modern hospital, stress integrated treatment services, from physical to mental care should be meticulous. Depending on the area of ??use, the selection of the appropriate color and pattern and overall style to match the new construction, to achieve the best results. Such as the use in the ward in soft neutral warm, can effectively relax the patient; in children's wards, choose bright colors atmosphere can give children a relaxed and with people's desire to increase and actively cooperate with medical treatment. Prefabricated prefabricated plastic runway plastic runway, a sports ground or track, especially a flat prefabricated plastic track with a solid structure. It contains a friction surface layer, shock-absorbing layer and shock-absorbing layer disposed between the adhesive layer and the ground, characterized in that: its shock-absorbing layer is a solid sheet plain structure. After the utility model in prefabricated plastic runway in the shock-absorbing layer with a plain sheet-type structure, can complete bond between the shock-absorbing base layer and the adhesive surface is 100%, so not only can ensure that it has a traditional prefabricated plastic runway should the use of functions, but also prevents seal the air or volatile components and so on in shock-absorbing layer of the runway, which can effectively prevent the emergence of a runway in use or under high temperatures from the dark, off layer, even if the use of prefabricated plastic runway reliable, and less maintenance trouble, and thus also significantly prolong life.
