Who knows the installation process of sports flooring

First, the construction conditions of basketball wood flooring.

1. The civil works of the wooden floor are completed before construction, the construction site is neat and clean, and the ground construction quality meets the requirements of architectural design; It should be waterproof, moisture-proofed, and air-proofed;

2. After the installation of indoor water, electricity, steam, ventilation and other installation projects, the water network pipeline is confirmed to have met the design requirements and is used normally after the pressure test;

3. Avoid cross construction. If it is really necessary for cross construction, it must be negotiated by the owner, the general contractor, the project supervisor, the installation team, etc., to clarify the responsibilities and reach a consensus. and form a written summary;

4. Determine the moisture content of the floor material, the ground humidity and the atmospheric humidity.

Second, the construction equipment of basketball wooden flooring.

1. Equipment, tools and instruments: level, polisher, portable planer, portable cutting machine, spray gun, nail gun, electric hammer, level and common tools for construction and woodworking;

2. Materials and materials: all kinds of materials required before construction are transported to the designated place, properly stored and kept according to the product performance, and the storage quantity meets the construction schedule;

3. Inspection of construction conditions: check whether there are construction conditions, and submit matters that do not meet the construction requirements to the relevant departments for negotiation and resolution in writing;

4. Preparation of relevant systems such as construction progress, on-site management, etc

Establish a construction supervision team: determine the responsibilities of the members of the construction supervision team;

Preparation of construction schedule: Preparation of construction schedule according to the plan.

5. Carry out technical, safety, fire prevention, anti-theft, and civilized construction education for construction personnel, abide by construction specifications, obey on-site management, and implement rules and regulations.

3. Ground leveling and division of basketball wooden floor;

1. Leveling and cleaning the site of cement floor and wall (where the baseboard is installed).

2. Using the 9-point method, use a level to determine the horizontal plane and mark the side wall;

3. Determine the position of the outer dividing line and mark it on the side wall;

4. Confirm that the cross is in the same horizontal plane, the convex part is smashed flat, and the recess part is leveled by drawing design materials;

5. The sports wood floor is coated with anticorrosive materials on the surface of the skid.

The first step is to draw the position line of the keel and the cushion block on the construction base surface.

The second step is to test the height difference of the base surface with a special level, and the height difference within the range of 3m ruler shall not exceed 2mm.

The third step, the leveling cushion block is installed on the reference point, and the elevation error of the cushion block shall not exceed 1mm.

The fourth step is to install an elastic pad on the leveling pad.

The fifth step is to install the keel of the specifications required by the contract.

Sixth, cooperate with the civil engineering unit to install the embedded parts of the sports floor.

The seventh step is to stagger the solid wood floor, spread it on the keel, and fix it with floor nails.

Step 8: Lay a moisture-proof film on the wool floor.

The ninth step, the sports wood floor surface layer is installed on the wool floor, which is required to be in a straight line longitudinally.

Step 10: Polishing and painting the surface layer of the sports wood floor.

If you want to hit the ground keel, the keel and the floor are 5 cm high.

1. Check the quality of the panel before the device;

2. Lay the central floor along the direction of the central keel one by one, the appearance is common with the design elevation, located in the center direction, the edge is in a straight line, and is reinforced from both sides after qualifying, the center row floor is a tenon type on both sides, and the steel nails are nailed at both ends and every 400mm in the middle during the reinforcement, and smashed into the floor, the floor shall not be damaged, and the nail hole is flat and lubricated;

3. Lay other floors along both sides of the central floor at the same time, and the adjacent floor joints should be staggered during the laying process, and there should be a gap of 3-5mm between the floors and the floors, and they should not be smashed too tightly to avoid damaging the surface and edges and corners of the floor;

4. When the floor needs to be truncated, the front side is down, and the burr sits on the reverse side, which is cut off and smooth, and it is regular;

5. The construction cycle should be tightly organized, pay attention to the changes in the external environment, pay special attention to the pollution damage of water, steam pollution or hard foreign bodies, oil, dust, flammable products and other hazardous substances to the floor, and personnel who have nothing to do with the wooden floor construction project shall not enter the construction site without permission, and strengthen the supervision of the construction site;

6. The baseboard device is fixed with steel nails nailed into anticorrosive wood bricks, and the nail head is smashed into the wood, and the nail hole is leveled;

7. The skirting board is reasonably arranged, the joints of the exhaust ventilation holes are uniform and common, and the joints of the skirting board at the corners of the building should be cut at a 45-degree angle, cut straight and flat, lubricated, and the joints are tight; The baseboard device should pay attention to cleaning the debris in the ventilation slot;

8. Harmonious cooperation with relevant engineering interfaces when the baseboard device is installed;

1) Make the ground flat, clean and dry, and apply waterproof paint twice;

2) According to the ground elastic line, the wooden frame (commonly known as the wooden joist) is directly erected. The cross-sectional size of the wooden frame body is 3omm 40mm or 4omm 50mm, and its connection method is half-groove buckle, and glue and nail at the buckle joint. After that, use a percussion drill to drill holes in the wooden frame and the ground, fix it with the ground with bolts, and check whether the frame is kept level.

3) Nail the base panel to the wooden frame. The base panel can be made of thick wood plywood or thick solid wood slats, and the plywood edges and the ends of the wood slats are all needled on the center line of the wood frame.

4) According to the size of each floor and the size of the room area, determine the floor puzzle and play the line, usually in square format, herringbone pattern, stepped type, etc.

5) Test laying according to the elastic line, the core of the board is facing up, the sapwood is facing down, and the width between the board is not more than 1mm. After repeated adjustments, the numbering is carried out, and the middle of the numbered living room is paved around during construction. When laying to the foot of the wall, a vacant space with a width should be left, and the empty space should be stuffed with wooden blocks and pressed against the water floor, and the jacking block wooden wedge at the beginning end should be tightened to arrange the floor tightly.

6) Use a round nail with a length of 2 times the thickness of the board, smash its head flat, and nail it diagonally from the concave corner of the board. In the case of hardwood boards, use a hand drill to drill a hole with a diameter smaller than a round nail diagonally to prevent needles from cracking the wood floor.

7) After the ground is cleaned, first plane it roughly according to the vertical wood grain, and then plane it carefully in the direction of the wood grain, and then polish it. The total thickness of the planing mill does not exceed.

8) Remove the top tight blocks around the ground, and close the edge of the floor, and use long wooden strips or wooden floor strips for retraction.

9) Paint the floor after polishing, and wax after drying.

1. Clean, remove the debris and floating ash on the foundation ground, level the ground, and measure it with a 2m ruler, with a maximum chord height of 3mm.

2. Use an ink fountain to play the line into a grid, and the spacing between the two lines is 300mm+3mm.

3. Use an electric hammer to open a hole in the ground, the hole depth is 50mm-60mm, and nail it into a wooden wedge, which must be dry and stable and not loose.

4. Open the baseboard hole, the hole distance is 500mm 10mm, and nail into the wooden wedge, which must be dry and stable and not loose.

5. Lay PE film, PE film should be stacked on top of each other for more than 200mm, glued and compacted with 60mm wide tape, and 50mm on the wall. Sprinkle with insect repellent powder.

6. Fix the keel firmly with keel nails, and leave a distance of 10-15mm between the keel and the wall or other ground materials.

7. Lay the floor mat, the floor mat can not overlap, and the seams should be glued and flattened with 60mm wide tape. The edge of the wall should be 30mm-50mm, and if it is damaged, it should be pasted with tape.

8. Lay the plywood, the thickness is 5mm, and the moisture content is 7%-12%. The area of each splint should not exceed 600*1200mm, and 8-12mm expansion joints should be left between each splint.

9. Pre-paving sorting, dismantling all floors and pre-paving as a whole, the color difference and pavement effect must reach a consensus with the customer, and adjust until the customer is satisfied, otherwise it will not be paved.

10. Paving the floor, 8-12mm expansion joints must be set aside on all sides, nailed, drilled obliquely at 45° with a hand electric drill, and then driven into the special nails for the floor, and air nails shall not be used. The number of nails per floor shall not be less than three. (Note:.)

The drill bit is thinner than the nail, otherwise the floor will be loose and unusual).

11. After the paving is completed, clean up the debris in the expansion joints and install the baseboard. After the installation is completed, clean in the direction of the floor.

Before the construction of the sports wood floor of the basketball court, the flatness of the site is tested, and the 3m ruler is required to measure, and the positive and negative errors within the radius of 3m are not more than 3mm.

Communicate with Party A before the goods enter the site, and the construction can only be carried out after the materials are inspected and qualified. The elastic shock-absorbing cushion is bonded to the laminate with strong all-purpose adhesive at an interval of 500mm to 500mm. Then turn the shelves over (with the side glued to the cushion facing down) and lay them down.

After the installation of the shelf is completed, the panel is paved, the middle line is marked on the bottom plate, the 3mm expansion gap is left, and the paving is carried out according to the direction of the court, and the panel is paved from the middle to both sides, and the panel is fixed with "L" type barbed anti-detachment nails.

The details are as follows: 1. The ground is staked out according to the area of Party A and the specifications of the court.

Second, the keel fixed lofting.

3. Lay moisture-proof film, and the site is full.

Fourth, the solid wood keel is treated with antiseptic and insect-proof.

5. Fix the solid wood keel.

6. Adjust the keel.

7. Lay the splint.

8. Lay maple panels.

9. Wood floor sanding.

10. Topcoat treatment.

Ten. 1. Draw a line.

Sports wood floor is a kind of functional wood floor different from ordinary wood flooring, due to the particularity of sports flooring, sports flooring must have sports, protection and technical performance, but the installation must be installed in accordance with a reasonable method, which is a safety guarantee for basketball stadium players. Let's talk about the installation process of sports wood flooring.

1. Construction site handover: In order to ensure the installation quality of sports wood flooring, Party A shall provide a standard baseline (0) before entering the construction site, and the installer shall detect the horizontal error of the site according to the benchmark, and the positive and negative error of the cement base surface of the venue shall not be greater than 5mm.

2. Site cleaning: Before the installation of the sports wood floor, first check whether the ground is waterproof, especially a layer of ground, and then clean the site and remove the cement mortar floating.

3. Instrument leveling: according to Party A's requirements for sports wood flooring, the cement foundation surface of the venue is leveled with a level, and the height difference is checked.

Fourth, put the baseline: according to the construction design drawings every 400mm 400mm center line distance to release the wooden keel installation line.

Fifth, find the reference point: use a level of about 3m to determine the level of 0 at the rubber elastic leveling pad.

6. Put down the keel: the lower keel is placed on the rubber leveling pad according to the 400mm center spacing, the ends of the two keel joints should be placed on the rubber pad, and the lower end of the joint of the two keels that are not on the rubber pad should be reinforced with wooden cushion blocks.

7. Elastic rubber pad installation: On the lower keel, the position of the rubber leveling pad is taken as the benchmark, and the elastic rubber pad is installed every 400mm interval, and the lower keel is fixed with 50 air nails.

8. Place the upper keel: the upper keel spacing is 400mm, the upper and lower keels are installed in a cross type, the keel is reinforced with 100 self-drilling wires, and the junction of the two keels ends is connected with 50 gas nails, and the keel end saw mouth should be treated with anti-corrosion.

9. Keel leveling of sports wood floor: After the keel is pre-installed, the third leveling must be carried out, and the height error must be reduced to within 2mm of the 3m level, and the next process can only be carried out after all levels reach the standard.

10. Installation of raw floor: In order to make the negative force of the wooden floor uniform, the raw floor should be installed vertically, and 20-40mm expansion joints should be reserved at the closing point of the wool board and the wall, and the installation of the raw floor should be fixed with U-shaped iron nails. Remember, the installation of sports wood floor-wool boards must have expansion joints on the wall.

Ten. 1. Laying moisture-proof film: Spread the special moisture-proof film for sports wood flooring according to the direction of panel laying, the joints should avoid overlapping, and the joints should be adhered with pressure-sensitive tape.

Ten. Second, sports wood floor panel installation: after the completion of the above workload, the panel can be installed, the basic requirements of the panel installation is the longitudinal surface of the venue, and the lateral direction should be the wide surface of the venue, so as to reduce the expansion and expansion rate of the floor.

The installation process of sports wood flooring basically includes ground finishing, opening baseboard holes, thoroughly cleaning the ground, laying moisture-proof film, laying floor mats, pre-selecting color separation, trial paving, paving, hammer tapping the floor splicing, installing springs at the ends, installing baseboards and cleaning the finish.

The whole process of construction of sports wood flooring needs to comply with ISO9001, ISO14001 and ISO45001 quality management system certification, improve installation quality and reduce safety risks.

In the wood floor paving stage, from the ground treatment to the treatment of the structural system to the installation of the panel, all links must meet the relevant technical requirements and acceptance standards, and there can be no defects that affect the use of the wood floor, and can not be greater than 70% of the allowable deviation value.

The structure of sports wood flooring is mainly composed of surface floor, raw floor layer (load division layer), keel layer, moisture-proof layer and elastic cushion block. The use, performance index requirements, cost and materials used in the structural layer of sports wood flooring are different

1. Panel flooring: refers to the outermost floor used for sports wood flooring, which is the contact panel between athletes and the floor in sports wood flooring applications.

2. Raw floor layer: refers to the plate layer that is close to the lower part of the surface layer floor and plays the role of leveling, increasing strength and dispersing load.

3. Keel layer: refers to the supporting skeleton installed under the surface floor or under the wool floor layer.

4. Moisture-proof layer: refers to the isolation or moisture-proof material placed between the surface floor and the raw floor layer or keel layer and the base layer of the building structure (cement floor).
