8. The net distance between the upper keel and the keel is 380mm. The upper and lower keels are installed in a criss-cross type. The junction of the two keel ends is connected with 50 air nails.
Nine, keel leveling After the keel pre-installation is completed, the level error is reduced to within 3cm.
Ten, install the wool floor In order to make the wooden floor evenly, hair floor straight shop installation, wool board and the wall edge should be reserved 0.9-3mm expansion joints, hair floor installation with nails fixed.
XI. Laying a damp-proof film Laminate the floor-specific damp-proof film according to the direction of panel installation. Joints should be avoided.
Twelve, UV lacquer panel installation After completing the above workload, the panel installation can be carried out. The basic requirements for the installation of the panel are the long side of the stadium in the vertical direction and the wide side of the venue in the lateral direction to reduce the expansion rate of the floor expansion.
The panel should be properly matched to the length of the floor.
The installation panel should be connected with special floor nails. The floor nails should be punched into the board to avoid affecting the joints.
The crack of the panel from the joint shall not exceed 4mm, and the difference between the joints shall not exceed 5mm. 10-40mm expansion joints should be reserved at the edges of wood floors and walls.
XIV. Installation of closed wooden lines Because the wooden floor has the characteristics of wet expansion and dry shrinkage, each site must reserve expansion joints when paving the floor. In order to make the floor and the wall of the joint beautiful, must use wood. Lines are reserved for expansion joints, and the wood line can be closed by the shaded wood line.
Fifteenth, installation characteristics The wooden floor is currently paving the use of wooden floor supply length of 1800mm specifications arbitrary seam paving. It adopts double dovetails with four-sided male and female tongues and grooves, which is anti-varying, strong and durable, and easy to install. The surface treatment of the wood floor includes that the base layer contains no formaldehyde.
The uniform color of the wood surface is pale and has perfect light reflections, thereby reducing the overall need for artificial lighting.
Wooden floors for sports provide a perfectly controlled balance of elasticity and ball resilience, satisfying athletes' requirements for fast balls such as basketball, volleyball, handball and basketball. High impact absorption and ideal friction features reduce the risk of sports-related injuries and improve overall comfort during gymnastics, aerobics or classical dance.

Our factory has a skilled team of production, installation and management. We are good at hardships and can perform outstanding construction tasks.
17. Characteristics of sports solid wood flooring The design of gym sports wood flooring must be a professional structure-type suspension sports floor that can satisfy the competition of basketball, tennis, volleyball, table tennis and other competitive events. It is a perfect sports function. The design of the wooden floor project in addition to meeting the fitness requirements in the structure, should also reflect the natural environmental protection in the selection of materials; in other wood flooring projects in this project, the design should reflect the natural, harmonious, environmental protection, fashion According to the characteristics of this project and the whole process of the overall construction, when the finished wooden floor project is completed and accepted, it fully meets the national requirements for sports floor design specifications and your floor-to-floor height restriction.
1, the use of functions: sports wood flooring from the structural design and material selection must meet the characteristics of human movement mechanics and material mechanics, able to bear long-term athletes during the movement to the floor of the strong impact force, shear force. At the same time, it can meet the athletes to play the competitive level of the friction coefficient (the installation process and coating process of wooden floor coverings), the ball's resilience, shock absorbency, load bearing and other special physical requirements.
2. Protection function: athletes inevitably have to perform various strong actions such as high and falling in the course of sports competition, and the wooden structure of wooden floor must be able to absorb the maximum energy, reduce the impact force and rebound to the human body through the floor. , to achieve the protection of the human body.
3. Environmental protection function: The indoor competitive sport is an advanced indoor cultural and sports activity that has only emerged in economically developed countries in recent years. China has become popular since 2007. As the indoor competitive sports require high facilities, the investment is huge. Especially in the design, the air quality of the human body breathing in large amounts of vital capacity must be considered. In order to achieve this goal, the environmental performance of the building materials for the indoor arena is even higher. In particular, the flooring materials must be highly environmentally friendly.
4. Decoration function: In order to meet the lighting requirements of indoor sports competition activities, the selection of wood species for wood flooring is very strict. The first wood species is hardwood, which can resist impact force; secondly, high stability of wood is not suitable for deformation; The light color has a good reflective ability, and can reflect the natural environmental protection, return to nature, noble and elegant decorative effect.
Eighteen, sports floor is different according to the design style of each manufacturer at present, its material and structure are not all the same. The following are the most popular genres:
All-natural solid wood structure: All wood components in the all-natural solid wood structure are processed using high-quality wood logs. The production process is simple, waste of log resources and material costs are large, but the use of superior effects, comfortable pedaling, no environmental protection , is the highest level in the sports floor.
Solid wood multi-layer structure: In order to save forest resources, the wool floor in this structure is made of solid wood plywood. The surface layer of the surface layer board generally uses the above-mentioned panel material with a thickness of 1 mm to 3 mm to use the decorative surface, and the lower substrate generally uses a low-cost fast-growing material. Wood, this structure has high wood utilization rate, low material cost, but high production cost and complicated process.
According to the requirements of international sports floor design specifications, this project recommends the use of all-wood materials for the ventilation structure of the upper and lower keels that are popular in the world today. Because the structure uses all natural wood materials for material selection, it can guarantee people's performance in the competition. The breathing of vital capacity is free from the inhalation of harmful volatiles. In the structural design, the elasticity of the natural wood fiber after being subjected to external force is ingeniously used to protect the leg of the athlete from impact damage caused by landing. This is because in this design The rubber leveling cushion made by our company's patented rubber products made of natural rubber can absorb a large number of people's impacts in sports, thus effectively protecting the athletes and giving the structure the best feeling and comfort. It can carry the impact load that the athlete produces to the wood floor in the sport.
