Product display and analysis

  

Products In the design process, the biomechanical needs of athletes are taken into consideration three-dimensional network of internal structure enable the runway to has excellent elasticity, strength, toughness and shock absorption effect, effectively reducing the athlete's muscle fatigue and micro-injury. The finish product is composed with the upper and lower layers with unevenly patterns; the upper layer is colorful composite rubber, with the performances of long-term resistance to ultraviolet light, changing climate and weather conditions; unevenly pattern surface design provides excellent anti-skid, anti-sticker, anti-wear and anti-reflective effects. The lower layer is black composite elastic material, with unevenly pattern on the bottom, which increases the anchor density between the runway material and the base surface to the most, and at the same time, by transmitting the elastic force generated instantly from the impact on the air in the hole to the athletes, effectively reducing the impact of the movement

2, preparation before construction
Tools: plastic mixer, professional rake, trowel, professional knife, level, total station, rolling cylinder, hand pressure gun, level ruler, steel tape, box, scales, trolleys, mixing bucket and so on.
B. The main material: prefabricated rubber coil runway (13 mm thick, 1.22 m wide, the length of any), special adhesive.
C. Auxiliary materials: cement nails, PVC troughs.
3. Detection, dressing, cleaning
A. For the laying of asphalt concrete foundation has been flatness error test, with three m ruler detection error shall not exceed 3mm.
B. For the laying of asphalt concrete foundation for the density test, the density of less than 95% are required to do intensive treatment (usually fine asphalt concrete mix in the AC10 and more than AC10 density must be dealt with).
C. For local flatness error of more than 3mm and the location of the water, polished or filled with the method to deal with, until qualified.
D. Grinding method --- will be local high with a terrazzo grinding.
E. Fill method --- the use of special fill plastic (self-leveling glue) fill.
(1): 3: 4: 8: the amount of mixed mixing evenly into the scene, the use of styrene-butadiene-free, With scraping rake along the base surface scratched, but pay attention to the reinforcement layer can not scratch the thickness, fill the gap can be).
G. The audience clean up.

 

Place the line
1, the use of the total station in accordance with the sports technology and competition rules and design requirements for lane positioning and line, and do a good job.
2, do a good job separation area positioning line, and do a good job.
3, repeat the line, the calibration can be carried out before the rubber sheet laying.

 

Laying process
1, laying order:
A. The runway is usually laid out from the inside to the outside - from the first, the second ... to the last (the first half can be laid in the semicircular area).
B. End of the section is laid.
C. Auxiliary area laying.
2, laying method:
A. Runway: from the runway 110 meters (or 100 meters) from the end of the run (the first) began to shop the first straight → after the end of the bend at the end of the curve → then follow the shop opposite the road straight → then shop to the starting point And the first shop with the first straight → according to the above method shop the second ... ... to the last one.
B. Drainage surface: the first straight section, after the shop section.
C. Semi-circular area: from the outer arch to the semi-circular arc, usually using cross-laying method (with a javelin throwing area of ??the semicircle can be vertical shop).
D. End of the line section: from outside to inside laying.
E. Auxiliary area: straight section from the inside to the outside laying, the eighth corner of the outer area from outside to inside laying.
F. Each pavement should be positioned before the test shop, and do the necessary pruning.
3, adhesive glue mixing system
A, material: adhesive adhesive material is composed of group A, group B, driers.
B, material ratio requirements: A group: Group B: driers = 1: 5: amount.
C, stirring: the first group of materials into the mixing tank, and then B group of materials into the mixing bucket, stirring 1.5 minutes, then add the drier for 1 minute, after the mixing of the material quickly into the fixed Bit of the web laying area.
4, the main runway membrane laying
A, material: 13 mm thick, 1.22 m wide, each roll about 20 meters, dark red, adhesive glue.
B, will be a special adhesive compound after mixing into a well-positioned and through the trial site of the road (after the test floor in situ winding), according to the width and length of each roll with a rake or trowel Knife will glue glue scraping uniform, the amount of rubber is about 1.5 kg / ㎡, and then the rubber sheet roll paste paste. Rolling, the edge of the roll with a roll in the roll surface rolling, out of the air, improve the adhesive effect. And then in the laying of the coil around the pressure on the red brick, to ensure that the surrounding bonding firm.
C, bonding, the vertical interface using the flat push method construction, horizontal interface using pre-push method of construction (pre-3 ~ 5 mm or so), as far as possible at the seams seamless mouth.
D, bonding, pay attention to the joints at the adhesive should be full. Scraping adhesive, in the vertical or horizontal seams, the use of trowels in the seams at the scraping, that is, the side of the web in the side of the rubber material will be more scraping some, into a certain angle to pave After the coil is not spilled for the degree of control to control the amount of rubber joints. If there is overflow rubber, should be promptly cleaned up.
E, corner bonding, the use of natural arc extension method for laying. Construction, each laying, there will be a part of the arc at the arc up, is a normal phenomenon, only a little pressure can be flattened. In addition, should pay special attention to the interface of the fixed, if necessary, plus fixed with cement nail fixation, to be firmly bonded and then pull the nails.
I. Paste length is generally controlled at about 20-25 meters.
On the day before the completion of the runway longitudinal and horizontal joints to check and found that the joints are not filled with plastic, you can use hand pressure gun pressure glue method to fill the vertical and horizontal joints, to be dry after the use of cutting knife Flattened.
5, thick area of the material laying
A, thickening area requirements: thickening distinction between 20 mm thick thick area (for long jump, high jump, javelin and pole high jump runway) and 25 mm thick thick area (for the barrier pool). The surface elevation of the thickened area is the same as that of the surroundings (so the thickness of the thickening zone should be reserved when the foundation construction is required).
B, due to the physical properties of the material requirements, the coil can only be 13 mm thick prefabricated, 20 mm thick area construction by 13 mm coil + 7 mm hybrid plastic laying, barrier pool thickening area construction by 13 mm coil + 12 mm mixed plastic laying.
C, mixed plastic materials: Group A, Group B, driers, black rubber particles
Matching requirements: Group A: Group B: driers = 1: 4: amount, black rubber particles by 30% of the addition of ethylene.
Ii. Mixing plastic material mixing and laying: First group of materials into the mixing tank, and then B group of materials into the mixing tank, stirring for 1 minute, then add the drier for 1 minute, and finally add black rubber particles Stirring for 1 minute, after the rapid mixing of the material will be poured into the fixed area of ??the thickening of the area laying area. Mixed plastic material for the self-leveling material, pay attention to control the laying of the thickness can be. In the mixed plastic material curing (about 12 to 24 hours) before sticking the membrane.
E, thick areas of the laying of the same method.
