Description

Technical Field

[0001] The invention relates to the field of wood floor construction, in particular to a method for quickly leveling an indoor court sports wood floor. Background Art

[0002] Sports wooden flooring usually includes a keel laid on the ground, a subfloor laid on the keel, and a panel laid on the subfloor. The keel usually has two layers, the upper keel is composed of a number of upper wooden squares, and the lower keel is composed of a number of lower wooden squares. Both the upper wooden squares and the lower wooden squares are wooden rectangular rods. Sports wooden flooring has excellent load-bearing performance, high shock absorption performance, and anti-deformation performance. It has excellent impact absorption performance and can effectively prevent athletes from sports injuries. However, sports wooden flooring is easy to absorb water and moisture, which can easily cause mold and damage to the sports wooden flooring. Therefore, indoor courts usually install sports wooden flooring on the ground made of cement as a sports venue. However, the ground is difficult to level because the cement shrinks when it solidifies and hardens. Therefore, when installing the sports wooden floor on the ground, the sports wooden floor needs to be leveled.

[0003] The existing construction method for leveling sports wooden floors usually involves first using a level to measure, laying cement mortar on the ground, and using a cement floor grinder to partially level the ground. After the cement mortar solidifies, a moisture-proof film is laid on the ground, and then a keel is laid on the moisture-proof film. Then, a subfloor is laid on the keel, and then a moisture-proof mat is laid on the subfloor, and then a panel is laid on the moisture-proof mat to make a sports wooden floor.

[0004] With regard to the existing construction method for leveling sports wooden floors, cement mortar is used to level the ground, which increases the cost of making sports wooden floors. This method still has room for improvement. Summary of the invention

[0005] In order to reduce the cost of manufacturing sports wooden floors, the present application provides a method for quickly leveling indoor court sports wooden floors.

[0006] The present application provides a method for quickly leveling indoor sports wooden floor using the following technical solutions: A method for quickly leveling an indoor sports wooden floor comprises the following steps: Step S1: laying a moisture-proof film on the ground; Step S2: placing a rubber pad on the moisture-proof film; Step S3: placing a keel on the rubber pad, placing wood chips between the rubber pad and the lower wood, using the wood chips for leveling, and then fixing the upper keel to the lower keel; Step S4: first install the subfloor on the keel, then lay the moisture-proof mat on the subfloor, and then lay the panel on the moisture-proof mat.

[0007] By adopting the above technical solution, when it is necessary to install the sports wooden floor on the ground, rubber pads and wood chips are used, so that the rubber pads and wood chips replace cement mortar to level the ground, reducing the work of laying cement mortar on the ground and then using a cement floor grinder to locally level the ground, thereby reducing the cost of purchasing cement mortar and reducing the cost of making sports wooden floors. At the same time, the rubber pads and wood chips are used to raise the keel, reducing the situation where the keel is raised by using wood chips alone, which results in the need to consume a large amount of wood chips. The wood chips can be obtained by processing the upper and lower wood squares, and the price of the rubber pads is usually lower than that of the upper and lower wood squares, further reducing the cost of making sports wooden floors. At the same time, the rubber pad is placed between the moisture-proof film and the keel. The elasticity of the rubber pad is greater than that of the lower wood square, which reduces the situation in which the lower wood square is easily scratched by the moisture-proof film when adjusting the lower wood square during the installation of the keel because the lower wood square is in direct contact with the moisture-proof film, thereby reducing the situation in which the moisture-proof film is damaged and needs to be repaired. At the same time, the height of the lower wooden block can be finely adjusted by setting the wooden pieces, thereby reducing the situation in which the rubber pad is in one piece and difficult to cut, resulting in difficulty in finely adjusting the height of the lower wooden block.

[0008] Preferably, in step S1, the reference lines of the lower keels and the reference height lines of the sports wooden floor are first calibrated on the walls on four sides of the indoor court, and then a moisture-proof film is laid on the ground.

[0009] By adopting the above technical solution, when placing the lower wooden block on the rubber pad, a ruler is placed on the top of the lower wooden block, and the reference line on the wall is referred to. By adjusting the thickness of the wood piece placed between the lower wooden block and the rubber pad, the height of the lower wooden block is easy to observe, reducing the need to use a ruler to measure the height between the lower wooden block and the ground, and then calculate the height of the lower wooden block. However, the ground is difficult to level because the cement shrinks when it solidifies and hardens, which makes it difficult to use a ruler to accurately measure the height of the lower wooden block. This is conducive to increasing the speed of placing the lower wooden block on the rubber pad. By setting the reference height line, the height of the sports wooden floor can be checked by referring to the position of the reference height line during the installation of the panel, reducing the situation where the height difference on the surface of the sports wooden floor exceeds the allowable range when there is a thickness difference in the panel.

[0010] Preferably, in step S1, water is first sprinkled on the ground, and the position of the puddle is marked after a puddle is formed in the depression of the ground. Then, the reference line of the lower keel and the reference height line of the sports wooden floor are calibrated on the walls on the four sides of the indoor court, and then a moisture-proof film made of transparent material is laid on the ground.

[0011] By adopting the above technical scheme, the location of the ground depression is quickly found by utilizing the puddle formed by water accumulation in the ground depression, and then the location of the puddle is marked with paint. At the same time, a moisture-proof film made of transparent material is laid on the ground. When the height of the lower wooden square is adjusted by using the wood chips, the thickness of the wood chips is adjusted in advance with reference to the position of the paint, which reduces the need to adjust the thickness of the wood chips multiple times when the rubber pad is placed in the ground depression, which is beneficial to improving the efficiency of adjusting the height of the lower wooden square, thereby improving the efficiency of installing the sports wooden floor on the ground.

[0012] Preferably, in step S1, water is first sprinkled on the ground, and the position of the puddle is marked after a puddle is formed in the depression of the ground. Then, the reference line of the lower keel and the reference height line of the sports wooden floor are calibrated on the walls on the four sides of the indoor court. Then, a moisture-proof film of a transparent material is laid on the ground, and then a mark line for placing the lower wooden square is marked on the moisture-proof film.

[0013] By adopting the above technical solution, when it is necessary to place the rubber pad on the ground, the rubber pad is placed along the same marking line, so that when placing the lower wood block on the rubber pad, the rubber pad is more easily evenly distributed in the length direction of the lower wood block, reducing the work of adjusting the rubber pad to evenly distribute the rubber pad on the lower wood block after placing the lower wood block on the rubber pad, improving the work efficiency of placing the lower wood block on the rubber pad, thereby further improving the efficiency of installing the sports wooden floor on the ground. At the same time, by setting the marking line, it is reduced to detect the installation position of the lower wood block once for each placement of the lower wood block, further improving the efficiency of placing the lower wood block.

[0014] Preferably, in step S3, the keel is divided into several component areas according to the length of the lower wooden square and the upper wooden square, the length of the component area is consistent with the length of the lower wooden square, the width of the component area is consistent with the length of the upper wooden square, and the keels of the component areas are installed on the rubber pad in sequence from the four corners of the sports wooden floor installation position to the middle position of the sports wooden floor installation position.

[0015] By adopting the above technical solution, the keel is divided into several component areas, and the length of the component area is consistent with the length of the lower wood square, and the width of the component area is consistent with the length of the upper wood square, so that the keel of each component area is composed of complete upper wood squares and lower wood squares, reducing the work of cutting the upper wood squares and lower wood squares, which is conducive to improving the efficiency of installing the keel. By setting the keel of the component area to be installed sequentially from the four corners of the sports wooden floor installation position to the middle position of the sports wooden floor installation position to the rubber pad, the height of the lower wood square at the four corners of the sports wooden floor installation position is checked by using the reference line, so that the keel can be quickly installed from the four corners of the sports wooden floor installation position to the middle position while controlling the height of the lower wood square by referring to the reference line, thereby controlling the flatness of the keel, and further improving the installation efficiency of the sports wooden floor.

[0016] Preferably, in step S3, the height of the two ends of the lower wooden square is first adjusted using wood chips according to the reference line, and then the wood chips and rubber pads at the two ends of the lower wooden square are respectively fixed to the two ends of the lower wooden square, and then the remaining positions of the lower wooden square along the length direction are fixed to the rubber pads, and then the keels of the component areas at the four corners of the installation position of the sports wooden floor are laid.

[0017] By adopting the above technical solution, the heights of the two ends of the lower wooden square are first fixed to determine the height of the lower wooden square close to the reference line, and then the distance between the lower wooden square and the remaining rubber pads is measured to reduce the thickness of the wood chips, which is beneficial to improve the work efficiency of fixing the lower wooden square with wood chips.

[0018] Preferably, in step S3, the lower wooden square is first laid on the rubber pad on the side close to the reference line, and then the two ends of the lower wooden square are fixed to the rubber pad according to the reference line, and then the remaining position of the lower wooden square along the length direction is fixed to the rubber pad, and then the keel located in the component area of ​​the four corners of the installation position of the sports wooden floor is laid, and then the lower wooden square located at one end of the upper wooden square along the length direction and away from the reference line is adjusted until the upper wooden square is horizontal, and then the two ends of the upper wooden square are respectively fixed to the two lower wooden squares that have been laid, and then the lower wooden squares located in the component area of ​​the four corners of the installation position of the sports wooden floor are fixed, and then the upper wooden square is fixed to the lower wooden square.

[0019] By adopting the above technical solution, the lower wooden square close to the reference line is first determined, and the height of the lower wooden square far away from the reference line is determined by using the horizontal degree of the upper wooden square. Then, the installed lower wooden square is fixed to the upper wooden square, so that it is only necessary to adjust the top side of the lower wooden square to abut against the bottom side of the upper wooden square to determine the height of the remaining lower wooden squares, thereby further improving the speed of installing the sports wooden floor.

[0020] Preferably, in step S3, the lower wooden square is first laid on the rubber pad on the side close to the reference line, and then the two ends of the lower wooden square are first fixed to the rubber pad according to the reference line, and then the remaining position of the lower wooden square along the length direction is fixed to the rubber pad, and then the keel located at the component area of ​​the four corners of the installation position of the sports wooden floor is laid, and then the lower wooden square located at one end of the upper wooden square along the length direction and away from the reference line is adjusted until the upper wooden square is horizontal, and then the two ends of the upper wooden square are respectively fixed to the two laid lower wooden squares, and then the upper wooden square is fixed to the lower wooden square, and then the lower wooden square located at the component area of ​​the four corners of the installation position of the sports wooden floor is fixed, and then the fixing tube is sleeved on the lower wooden squares that are abutted against each other at one end along the length, and the inner wall of the fixing tube abuts against the outer wall of the lower wooden square, and the above operation is repeated until the keel of the sports wooden floor is formed.

[0021] By adopting the above technical solution, the lower wooden square that has been installed is connected with the lower wooden square that is to be installed and is in the same straight line with the installed lower wooden square by using the fixing tube, so that the installed lower wooden square and the fixing tube determine the height of the lower wooden square that is to be installed close to one end of the fixing tube, reducing the work of cutting wood pieces in multiple places and adjusting the height of the lower wooden square that is to be installed, thereby improving the installation efficiency of the lower wooden square. At the same time, the lower wooden square that has been installed is connected with the lower wooden square that is to be installed and is in the same straight line with the installed lower wooden square by using the fixing tube, and then a ruler is placed on the top of the lower wooden square that is to be installed, and the height of the lower wooden square that is to be installed is adjusted. The ruler is observed until the lower wooden square that is to be installed is level, and the height of the lower wooden square that is to be installed can be determined, further improving the installation efficiency of the lower wooden square, thereby further improving the installation efficiency of the sports wood floor.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up rubber pads and wood chips, the rubber pads and wood chips replace cement mortar to level the ground, reducing the work of laying cement mortar on the ground and then using a cement floor grinder to locally level the ground, thereby reducing the cost of purchasing cement mortar and reducing the cost of making sports wood floors. At the same time, the rubber pads and wood chips are used to raise the keel, reducing the use of wood chips alone to raise the keel, resulting in the need to consume a large number of wood chips. Wood chips can be obtained by processing upper and lower wood squares, and the price of rubber pads is usually lower than that of upper and lower wood squares, further reducing the cost of making sports wood floors.

[0023] 2. By setting the fixing tube, fixing the height of both ends of the lower wood first, and using the horizontality of the upper wood as a reference to adjust the height of the lower wood away from the reference line, it is helpful to improve the installation efficiency of the keel, thereby improving the installation efficiency of the sports wood floor.
