Gym floor installation process and precautions
Installation instructions for sports wooden floor: Construction process 1. Construction conditions 1. Before the construction of the wooden floor, the civil engineering is completed, the construction site is clean and tidy, and the ground construction quality meets the architectural design requirements; it should be waterproof, moisture-proof and air-proof;
2. The installation of indoor water, electricity, steam, ventilation, etc. is completed. After the pressure test of the water network pipeline, it is confirmed that it has met the design requirements and is in normal use;
3. Avoid cross construction. If cross-construction is really necessary, the owner, the general contractor, the project supervisor, the installation team, etc. must negotiate together to clarify the responsibilities and reach a consensus. and form written minutes;
4. Determine the moisture content of the floor material, ground humidity and atmospheric humidity. Sports wooden floor
2. Construction equipment 1. Equipment, tools and instruments: spirit level, polishing machine, portable electric planer, portable cutting machine, spray gun, nail gun, electric hammer, spirit level and common tools for construction and woodworking; 2. Materials and supplies: All kinds of required materials before construction shall be transported to the designated location, and shall be properly stored and kept according to the product performance, and the storage quantity shall meet the construction progress; Submit it to the relevant departments for negotiation. 4. Compilation of construction progress, site management and other related systems: ①Set up a construction supervision team: determine the responsibilities of the members of the construction supervision team; 5. Provide technical, safety, fire prevention, anti-theft, and civilized construction education to construction personnel, abide by construction specifications, obey on-site management, and implement rules and regulations.
Sports wooden floor
3. Leveling and dividing the ground; 1. Leveling and cleaning the cement floor and wall (where the skirting board is installed): 2. Using the 9-point method, use a spirit level to determine the horizontal plane and mark the side wall; 3. Determine the position of the dividing line on the outer side, Mark on the side wall; 4. Make sure that the cross is on the same level, the raised part is flat, and the recessed part is flat.Use drawings and design materials to fill and level; 5. Paint anti-corrosion materials on the surface of the skid. 4. Installation and laying of keels and small keels 1. Inspection, marking, sawing and lengthening of keels and small keels. 2. The length of the keel and the small keel shall be determined according to the requirements of the center distance of the drawing, and the length of the keel shall be reasonably determined under the premise of eliminating the defects, and the saw edge shall be straight and smooth; 3. Installation: The "middle keel" is laid continuously along the longitudinal center line of the site. The center line of the "middle keel" coincides with the center line of the marked surveying and mapping. The surface elevation conforms to the surveying and mapping elevation. The small keel can be laid, and it is perpendicular to the keel, clamped and nailed; There should be a certain gap, the keel and the small keel, the keel and the keel, and the small keel and the small keel meet the requirements; 6. Check the flatness of the plane composed of the keel and the small keel and mark it. After the inspection, use an electric planer for local leveling and apply anti-corrosion. Material. 7, keel installation and inspection.
5. Laying of fur floor 1. Both sides of the fur floor are planed, planed, and thickened, and the two ends are aligned; 2. The laying angle of the fur floor meets the design requirements of the drawings, and the ends along the edge are cut neatly, and the ends are flat with the keel and the small keel. 3. The joint of the end of the fur floor falls on the keel and should not be suspended in the air; when the fur floor is laid with the slabs, the width and width are evenly matched, and the joints are staggered; there is a uniform gap between the slabs. 4. The fur floor is nailed to the keel, the two ends and both sides of the fur floor, the steel nails are nailed to the keel, and the nail head is smashed into the fur board; Gross floor installation and inspection.
6. Laying of moisture-proof linoleum isolation layer Lay the moisture-proof isolation layer along the direction of the small keel, the surface of the moisture-proof material shall not have holes or tears, and the moisture-proof isolation layer shall be laid flat. 7. Panel installation 1. Check the quality of the panel before installation; 2. Lay the central floor one by one along the direction of the central keel. The surface is consistent with the design elevation, located in the center position, and the edges are straight. The floor is of tenon type on both sides. When reinforcing, nails are made at the two ends and every 400MM in the middle.Steel nails should be smashed into the floor so as not to damage the floor, and the nail holes should be flat and smooth; -5MM gap, do not hit too tightly to prevent damage to the surface and edges of the floor; 4. When the floor needs to be cut off, the front face is down, the burr is on the back, and the incision is smooth and neat; 5. The construction period should be compact, pay attention to the external environment Special attention should be paid to the pollution of the floor by water, steam pollution or hard foreign matter, oil, dust, flammable substances and other harmful substances, and personnel unrelated to the wooden floor construction project are not allowed to enter the construction site without permission, and strengthen the construction site. regulation;
*The last is the technical function. There is a big difference between the wooden floor used in the stadium and the civil wooden floor. Its load-bearing load and firm service life must meet the requirements of competition and training. For example, when the movable basketball rack and related sports facilities are moved on the wooden floor, the wooden floor Therefore, the floor structure is complex, with many layers, and the physical and mechanical properties of the material are required to be higher. In addition, there are also quality details such as the abrasion resistance and pollution resistance of the floor, the hardness of the paint film, the requirement that the surface layer is not easy to foam, and the strict control of chromatic aberration from the consideration of avoiding reflection.
