DETAILED DESCRIPTION

[0022] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a functional floor construction unit and a construction method thereof.

[0024] The embodiment of the present invention provides a functional floor construction unit, which is constructed as follows: Figure 1 As shown, it includes: a basic leveling pad 1, a first vibration-damping pad 2, a plurality of parallel and equally spaced lower wooden keels 3, a second vibration-damping pad 4, a plurality of parallel and equally spaced upper wooden keels 5, a sound-absorbing filler 6 for filling the cavity of the functional floor structural unit, a subfloor 7, an isolation and moisture-proof layer 8, a special wooden floor 9 and a floor glue 10, and the vertical projection of the upper wooden keel 5 is perpendicular to the lower wooden keel 3; a plurality of equally spaced first vibration-damping pads 2 are fixed to the lower surface of each lower wooden keel 3, and a basic leveling pad 1 is fixed under each first vibration-damping pad 2; a plurality of equally spaced second vibration-damping pads 4 are fixed to the upper surface of each lower wooden keel 3, and the upper wooden keel 5 is fixed on the second vibration-damping pad 4; the subfloor 7, the isolation and moisture-proof layer 8, the special wooden floor 9 and the floor glue 10 are laid on the upper wooden keel 5 in sequence.

[0025] The above-mentioned functional floor structural unit can realize or improve the three functions of wooden floor, namely protection, sports and technology. The double-layer keel and two-stage vibration-damping pad structure can realize better protection function of absorbing vibration and has better ground elasticity. The special wooden floor with stronger wood can bear sufficient load-bearing capacity, and the laid floor glue can protect the floor surface from damage.

[0026] By adopting the above technical solutions, a safe and comfortable sports environment can be provided for dance rehearsals and performances, sports injuries can be reduced, and the performance of athletes can be improved to a certain extent.

[0027] The base leveling pad should be made of wood, which is mainly used to solve the problem of uneven base and ensure that the upper first vibration damping pad 2 is placed vertically and stressed. Before installing the dance wooden floor, the base surface should be measured for flatness and leveled. For base surfaces with large unevenness, use leveling pads to make up for the difference to ensure the overall flatness of the base surface. When the flatness of the base is good, the base leveling pad may not be set. By setting the base leveling pad, the problem of poor base flatness can be solved, providing a flat and solid base for the functional floor, improving the paving efficiency and quality, and making the single first vibration damping pad 2 and the overall first vibration damping pad 2 evenly stressed.

[0028] The first vibration damping pad 2 uses a 10~15mm thick rubber vibration damping pad, which mainly provides shock absorption for the system. Rubber has a long service life and is not easy to corrode and deform, so rubber vibration damping pads are preferably used. The elastic pad material can also choose other suitable materials according to the different requirements of different venues, such as PU (Polyurethane), recycled rubber, PVC (Polyvinylchloride) and other materials. The shape of the first vibration damping pad 2 can be divided into rectangular, spherical, multi-point support type, etc., and the bottom shape can be flat, strip, spherical, etc. When selecting, it should be noted that the first vibration damping pad 2 should be able to bear all the loads on its upper part, and be easy to install, and have good elasticity, waterproofness, durability, and antibacterial properties. It maintains good elasticity when compressed, and the performance cannot be significantly reduced over time. The spacing of the first vibration damping pad 2 is 400mm~500mm, which needs to be determined comprehensively based on the use load and the elasticity requirements of the dance type for the wooden floor. By adopting the technical solution of the first vibration damping pad 2, the nonlinear elastic characteristics of the vibration damping pad can be utilized to absorb and disperse energy through deformation and recovery when subjected to impact or vibration, thereby effectively reducing vibration.

[0029] The material of the lower wooden keel 3 and the upper wooden keel 5 is generally high-quality pine wood, and solid wood or LVL (Laminated Veneer Lumber) wooden keel can be used, and anti-corrosion paint can be applied. The arrangement spacing of the lower wooden keel 3 and the upper wooden keel 5 is generally 400mm~500mm, which is the same as the arrangement spacing of the first vibration damping pad 2. The upper wooden keel 5 should be arranged vertically staggered with the position of the lower vibration damping pad, preferably staggered by 200mm~250mm. The second vibration damping pad 4 is arranged between the upper and lower keels, and a rubber vibration damping pad is used with a thickness of 2~5mm. By adopting the above technical solution, the stability of the system structure can be ensured, the direct contact of the keels and the generation of noise can be avoided, and at the same time, the vertical mutual movement between the keels can be ensured, sufficient elasticity can be provided, and the movement performance of the wooden floor can be improved.

[0030] The sound-absorbing filler 6 fills the cavity of the functional floor structural unit, such as Figure 2 The sound-absorbing filler 6 can be made of sound-absorbing rock wool or glass wool, which fully fills the cavity below the subfloor 7, from the bottom of the foundation leveling pad 1 to the top elevation of the upper wooden keel 5.

[0031] In some optional embodiments, such as Figure 3As shown, the upper surface area of ​​the upper wooden keel 5 is larger than the lower surface area of ​​the upper wooden keel 5. The larger upper surface area of ​​the upper wooden keel 5 can reduce the pressure of the subfloor 7 on the upper surface of the upper wooden keel 5, reduce the pressure generated by the reaction force of the upper wooden keel 5 on the subfloor 7, and avoid the subfloor 7 and its upper special wooden floor 9 and floor glue 10 from irreversible deformation due to the excessive pressure difference between the contact surface and the non-contact surface of the subfloor 7, which helps to extend the service life of the subfloor 7 and its upper special wooden floor 9 and floor glue 10. At the same time, the lower surface area of ​​the upper wooden keel 5 is smaller, which can make the cross-section of the upper wooden keel 5 smaller, so that the upper wooden keel 5 maintains good elasticity, which helps to absorb vibration impulse.

[0032] In some optional embodiments, such as Figure 4 As shown, the first vibration-damping pad 2 and the second vibration-damping pad 4 are located on the vertical line of the intersection center of the lower wooden keel 3 and the upper wooden keel 5. When the floor is under pressure, this structure can make the elastic deformation of the lower wooden keel 3 smaller, and the vibration impulse is mainly absorbed by the upper wooden keel 5, the first vibration-damping pad 2 and the second vibration-damping pad 4, which can make the ground elasticity smaller, and is suitable for venues that require smaller ground elasticity.

[0033] In some optional embodiments, such as Figure 5 As shown, the first vibration-damping pad 2 and the second vibration-damping pad 4 are staggered on the same lower wooden keel 3. When the floor is under pressure, this structure can make the lower wooden keel 4 undergo a larger elastic deformation than the lower wooden keel 4. Figure 4 The structure shown absorbs more vibration impulse. The vibration impulse is mainly absorbed by the upper wooden keel 5, the lower wooden keel 4, the first vibration damping pad 2 and the second vibration damping pad 4, so that the functional floor structural unit can absorb more vibration impulse than Figure 4 The structure shown is more, so the ground can be made more elastic, which is suitable for venues that require greater ground elasticity.

[0034] In some optional embodiments, referring to Figure 5 , the second vibration damping pad 4 is arranged on the upper surface between the lower wooden keel 3 and the adjacent first vibration damping pad 2, and the distance between the second vibration damping pad 4 and the adjacent first vibration damping pad 2 is equal. Under this structure, the second vibration damping pad 4 and the upper wooden keel 5 thereon are located between the adjacent first vibration damping pads 2, which can make the lower wooden keel 3 between the adjacent first vibration damping pads 2 play the maximum elasticity, and improve the overall elasticity and total vibration impulse absorption of the functional floor structural unit.

[0035] In some optional embodiments, such as Figure 6As shown, an arched plate 11 with a downward curved surface is provided between adjacent first vibration-damping pads 2 of the same lower wooden keel 3, the top of the arched plate 11 is not higher than the lower surface of the lower wooden keel 3, and the two bottom ends of the arched plate 11 are respectively fixed on the basic leveling pad 1 under the adjacent first vibration-damping pad 2, and the elasticity of the arched plate 11 is greater than the lower wooden keel 3. Under this structure, the arched plate 11 can absorb the vibration impulse transmitted by the lower wooden keel 3, protect the lower wooden keel 3, and improve the service life of the functional floor structural unit.

[0036] In some optional embodiments, the sound-absorbing filler 6 is a mixture of multiple sound-absorbing materials, each of which corresponds to noise of different wavelengths in the functional floor construction unit, and the proportion of each sound-absorbing material in the mixture corresponds to the proportion of noise of different wavelengths. Furthermore, the corresponding sound-absorbing material is filled near the sound source generating noise of different wavelengths.

[0037] In some optional embodiments, the isolation moisture-proof layer 8 includes overlapping PE (Polyethylene) films and non-woven fabrics. The isolation moisture-proof layer 8 is made of a fully-covered PE film and used in conjunction with non-woven fabrics, and the overlap between the widths is not less than 100 mm. The PE film widths are connected with a special waterproof tape to produce moisture-proof, isolation, and sound-absorbing effects. The isolation moisture-proof layer 8 can prevent indoor water and water vapor from entering the lower layer of the wooden floor and polluting and corroding the lower structure. The isolation moisture-proof layer 8 can also seal the sound-absorbing filler 6 and isolate it from the indoor use space to prevent the spread of cotton particles from damaging the health of dancers. As a fully-covered, closed, flexible connecting layer added to the functional floor construction unit, the isolation moisture-proof layer 8 can play a certain sound-absorbing role.

[0038] The subfloor 7 mainly plays the role of transferring load, and uniformly transfers the load received by the upper special wooden floor 9 downward to the upper wooden keel 5. The subfloor 7 can be made of solid wood board or multi-layer solid wood board.

[0039] The subfloor is laid in an oblique manner. In some specific embodiments, the width of the board is preferably 45 degrees to the length of the upper wooden keel 5, which can increase the contact area between a single subfloor 7 and the upper wooden keel 5.

[0040] In some optional embodiments, the diagonal line of the subfloor 7 on the horizontal plane is perpendicular to the long side of the upper wooden keel 5. Since the diagonal line is the maximum length of the subfloor 7, this structure can make the subfloor 7 of the same size have contact surfaces with more upper wooden keels 5, so that the pressure of the subfloor 7 is borne by more upper wooden keels 5, thereby enhancing the load-bearing capacity and vibration reduction capacity of the floor. Figure 7In the case shown, when the long side of the subfloor 7 is perpendicular to the long side of the upper wooden keels 5, the subfloor 7 has contact surfaces with 3 to 4 upper wooden keels 5 at most. However, when the diagonal line of the subfloor 7 on the horizontal plane is perpendicular to the long side of the upper wooden keels 5, the subfloor 7 of the same size can have contact surfaces with 5 upper wooden keels 5. The pressure of the subfloor 7 of the same size will be shared by the 5 upper wooden keels 5, thereby enhancing the load-bearing capacity and vibration reduction capacity of the floor.

[0041] The special wooden floor 9 should meet the load-bearing capacity required for dance rehearsal, performance, personnel activities, etc., and should be a hardwood floor or a pure solid wood floor. Preferably, pine, maple, oak, etc. are suitable for making the special wooden floor 9, and the wood is required to be hard, high in strength, anti-bending, wear-resistant, and corrosion-resistant.

[0042] The positional relationship of the various parts of the functional floor composed of functional floor structural units is as follows: Figure 8 and Fig. 9 shown. Figure 8 It is a vertical cross-sectional diagram parallel to the long side of the upper wooden keel 5. Fig. 9 It is a schematic diagram of a vertical section parallel to the long side of the lower wooden keel 3.

[0043] By adopting the above technical solution, the requirements of various dance performances, sports competitions, and training activities can be better met. Through the combination of floor structures, the injuries caused by vibration impulses to actors and athletes can be avoided to the greatest extent, which will affect the dance performance. The overall structure of the functional floor structure unit has strong shock absorption performance, which can effectively eliminate the impact force generated by actors when running and jumping, thereby protecting the ligaments, joints, spine and other parts of the human body and reducing the possible injuries to actors when they fall.

[0044] Another embodiment of the present invention provides a construction method of the functional floor construction unit, comprising the following steps: Marking the positions of the first vibration damping pad 2 and the second vibration damping pad 4 on the site; Arrange the basic leveling pad 1 according to the position of the first vibration damping pad 2, and use the basic leveling pad 1 for leveling; Fix the foundation leveling pad 1, the first vibration damping pad 2 and the lower wooden keel 3; According to the position of the second vibration damping pad 4, the second vibration damping pad 4 is fixed on the lower wooden keel 3, the upper wooden keel 5 is fixed on the second vibration damping pad 4, the cavity of the functional floor construction unit is filled with sound-absorbing filler 6, the subfloor 7 is fixed on the upper wooden keel 5, an overlapping isolation and moisture-proof layer 8 is laid on the subfloor 7, the special wooden floor 9 is laid on the isolation and moisture-proof layer 8, compacted, and fixed to the subfloor 7; and floor glue 10 is laid on the special wooden floor 9.

[0045] After the construction is completed, the position relationship of each part of the functional floor composed of functional floor structural units is as follows Figure 8 and Fig. 9 shown.

[0046] The present invention provides a construction method for the functional floor structural unit, which can lay the floor with good protection, sports and technical functions according to its structural characteristics, thus helping to improve the construction quality.

[0047] In some specific implementations, taking the construction of wooden floors in dance venues as an example, the construction method of the functional floor structural unit is further divided into the following steps: Step 1: Clean up the site and remove dust, debris and garbage from the site; Step 2: On-site measurement and layout. The shock-absorbing pads (including the first shock-absorbing pad 2 and the second shock-absorbing pad 4) are positioned with the longitudinal direction of the center line of the site as the reference line. Lines are drawn according to the designed spacing. The intersection of the vertical and horizontal lines is the position of the shock-absorbing pads. The ink lines must be clear and straight. Step 3: Leveling and constructing vibration damping pads. Temporarily place the first vibration damping pad 2 at the popped-up cross point. Measure the height of the bottom surface of the lower wooden keel 3 from the ground, use an infrared leveler to determine the height of the basic leveling pad 1, and use an infrared leveler to level the first vibration damping pad 2 one by one, use the basic leveling pad 1 for leveling, and fix it with a nail gun.

[0048] Step 4: Place the lower wooden keel 3 on the first vibration damping pad 2 according to the layout position, and use steel nails to firmly fix the first vibration damping pad 2, the foundation leveling pad 1 and the lower wooden keel 3. Use a 3-meter steel ruler to control the overall flatness error of all lower wooden keels 3 within 2mm of the 3-meter ruler.

[0049] Step 5: The second vibration damping pad 4 is glued and fixed between the upper wooden keel 5 and the lower wooden keel 3. The upper wooden keel 5 and the lower wooden keel 3 are arranged in a well shape and fixed with steel nails. The keel spacing is 400mm~500mm. Figure 5 As shown, the setting position of the upper wooden keel 5 should be staggered in the vertical direction with the position of the lower first vibration damping pad 2, with a stagger of 200mm~250mm.

[0050] Step six, fill the sound-absorbing cotton densely into the cavity, fully fill the cavity below the subfloor 7, from the bottom of the foundation leveling pad 1 to the top elevation of the upper wooden keel 5, and fill it layer by layer.

[0051] Step seven, use a whole piece of subflooring 7 as much as possible, stagger the subflooring 7 with appropriate gaps (for example 5-10mm) between each other, and lay it diagonally. The width of the board should be 45° with the length of the upper wooden keel 5. Use round nails to nail diagonally into the upper wooden keel 5 and fix it firmly. The flatness of the subflooring 7 is required to meet the requirement of not more than 3mm based on a 2m ruler.

[0052] Step 8: The overlap between the widths of the isolation moisture-proof layer 8 should be no less than 100mm. After being properly flattened, the seams between the widths are connected by sticking special tape.

[0053] Step nine, the special wooden floor 9 is installed starting from the middle of the site. A vertical line is drawn in the middle, and the floor is fixed on the subfloor 7 along the vertical line; it is laid from the middle to the surroundings or both sides at the same time, and each adjacent row of surfaces is staggered by more than 200mm. The special floor 9 is fixed with special nails, and the spacing between each nail is within 400mm. The spacing is about 1.2m, and a 1mm expansion joint is left. When the panel is nailed, the special wooden floor 9 must be pressed down by human weight to avoid the formation of a cavity gap between the special wooden floor 9 and the subfloor 7. The special wooden floor 9 is installed from the middle to the wall, and the distance from the wall is not less than 20mm.

[0054] Step ten, laying of floor glue 10, construction is carried out in the following order: 1. Clean the special wooden floor 9 and vacuum; 2. Apply (scrape) glue; 3. Dry glue according to product requirements; 4. Lay the floor; 5. Exhaust, trim corners, and remove excess glue; 6. Roll the floor surface; 7. Roll the floor again after 2 hours; 8. Perform finished product protection floor treatment, trimming, and polishing.

[0055] In some optional embodiments, the construction method of the functional floor construction unit further includes the following steps: Before pre-paving, use 40#~60# sandpaper to grind the self-leveling surface, remove the suspended particles and white water slurry layer on the surface, and grind the surface to a certain strength to be gray-black and shiny. After grinding, use a high-power vacuum cleaner to clean the ground.

[0056] Pre-laying: Before laying the floor, the floor materials of the unit should be unpacked and spread out in the site or an adjacent empty site for no less than 24 hours to allow it to recover and adapt to the temperature in the site.

[0057] The layout of the material should keep the arrow direction of the back of the floor consistent in the main part of the same occasion. It is best to have the longitudinal layout direction of the coil perpendicular to the light, which can improve the visual effect of the surface after laying. The layout is usually based on the right angle side of the entrance, and the other right angle side is used as the end of the material, which can reduce loss. The symmetrical parquet layout should be based on the center line of the venue.

[0058] Cutting: For weld-free splicing of coils, the two edges of the floor should overlap by 3cm when layout, with the smooth edge on top and the rough edge on the bottom. When cutting, measure 10mm from the smooth edge of the floor, press a ruler and use a trimmer to cut in one overlapping manner. Note that all joints should be cut in an overlapping manner. The layout of block materials should be cross-angled, and the floating point blocks should align the floating points. The same requirements should be met when cutting, especially for multi-color parquet, both the dots and the lines should be aligned.

[0059] Gluing: After cutting, the surface should be cleaned first, and the cutting residue, dust on the self-leveling surface and the back of the floor should be vacuumed. Half of the roll material should be lifted up for gluing, and a strip of floor should be left in place as a baseline for reference when laying. Large sites can be divided into several sections, depending on the number of construction workers and the amount of glue scraped at one time. When gluing block materials, the principle of dividing from the center to both sides should be followed, and the materials should be laid radially, gradually moving closer to the center. Large areas can also be glued and laid in sections.

[0060] Open time of glue application: Single-component glue has a drying time, and it can be laid when you feel a slight brushing feeling when you touch it with your fingers. Two-component glue has no drying time, and it can be laid immediately after scraping. You should pay attention to the fixed ratio, dosage and specified teeth of the two-component glue. When using, pour the stirred two-component glue into the use area in time to avoid leaving it in the bucket to accelerate curing and affect normal use.

[0061] Laying: When the glue drying time is appropriate, put down the lifted floor one by one in order, push and place gently, pay attention to the opposite sides, corners and lines. Lay according to the original requirements, and the laying workers should wear flat shoes to enter the site, close the site and control the movement of irrelevant personnel.

[0062] Exhaust: Immediately after laying, use cork exhaust boards to push from one end to the other in sequence to exhaust the back air.

[0063] Rolling: After exhausting, roll the glue in sequence with a 50 kg large roller in time without omission. Press the two-component glue again within 2 hours to ensure that there is no empty adhesion.

[0064] Inspection: After laying, check the joints of the floor, the cross misalignment of the blocks, whether there are height differences, warped corners, warped edges, bubbles, etc., and immediately remove the exposed glue on the surface of the floor.

[0065] The on-site acceptance of materials should focus on the size, specification, model, manufacturer, date, test report, and certificate of the first vibration damping pad 2, wooden keel, subfloor 7, special wooden floor 9, second vibration damping pad 4, and sound-absorbing cotton. The sound-absorbing cotton shall be constructed according to the design and specification requirements. For construction materials that need to be retested on-site, a retest should be organized. Only after the retest results are qualified can they be put into use in the project and implemented in accordance with the corresponding standards.

[0066] After the functional floor is laid, hidden acceptance should be carried out layer by layer, and hidden acceptance records should be formed and archived.

[0067] In the above method of this embodiment, the floor with better protection, sports and technical functions can be laid according to its structural characteristics, which helps to improve the construction quality.

[0068] Those skilled in the art can change the above sequence without departing from the protection scope of the present invention.

[0069] Any modifications, supplements and equivalent substitutions made within the scope of the principles of the present invention shall still fall within the patent scope of the present invention.

[0070] The "first" and "second" mentioned above indicate the distinction between different characteristics.
