Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a dry flooring system and its construction method. Background Technology

[0002] Currently, most floor construction in medical buildings relies on wet flooring systems. This involves laying cement first, allowing it to self-level and harden, and then laying the flooring. However, the long curing period for self-leveling cement in wet flooring slows down the overall delivery and use of medical buildings. Furthermore, because self-leveling cement is a fixed process, pipelines buried in the cement cannot be separated or modified later, making pipeline maintenance and repair difficult. In addition, the quality of self-leveling flooring is unstable, and there is a risk of cracking after long-term use. Once the cement floor cracks, the flooring will also crack, leading to quality problems in the building floor.

[0003] While current dry flooring systems address the shortcomings of wet flooring methods by employing raised floors (typically lightweight materials) and supporting components (such as bolts or screws), allowing for the installation of various pipelines beneath the raised floor, thus preventing cement cracking from affecting the flooring and facilitating pipeline separation for future inspection and maintenance, current dry flooring systems typically involve first fixing the flooring with nails or bolts, then supporting the flooring with these nails or bolts, and finally preparing the finish. However, the rigid connection of the nails or bolts makes it difficult to adjust the flatness of the supported surface. This results in uneven adhesive application during subsequent flooring finish bonding, leading to wrinkles or depressions in the finish, affecting both its smoothness and aesthetics. Therefore, providing a dry flooring system with high flatness is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a dry flooring system and its construction method to solve the technical problem that dry flooring systems in the prior art are difficult to achieve high flatness.

[0005] In a first aspect, this application provides a dry ground system, the ground system comprising:

[0006] The support unit includes an elevated floor panel, a hollow support assembly, and a foam adhesive layer. One end of the support bolt abuts against the ground. The foam adhesive layer is provided between the hollow support assembly and the ground. The other end of the hollow support assembly is fixedly connected to the elevated floor panel so that an installation space is formed between the elevated floor panel and the ground.

[0007] The finishing unit includes a first adhesive layer, a tenon-and-mortise structural substrate, a second adhesive layer, and a floor mat finishing layer. One side of the first adhesive layer is fixed to the surface of the raised floor panel, and the other side of the first adhesive layer is fixed to the bottom surface of the tenon-and-mortise structural substrate. One side of the second adhesive layer is fixed to the surface of the tenon-and-mortise structural substrate, and the other side of the second adhesive layer is fixed to the bottom surface of the floor mat finishing layer.

[0008] Optionally, the hollow support assembly includes a fixing nut, a hollow adjusting screw, and an elastic base. The fixing nut is fixed to the side of the raised floor panel. One end of the hollow adjusting screw is screwed into the fixing nut, and the other end of the hollow adjusting screw is inserted into the elastic base. The elastic base is disposed against the ground, and the foam adhesive layer is provided around the elastic base to achieve flexible contact between the hollow support assembly and the ground.

[0009] Optionally, the adjusting screw includes a screw body and a hollow cavity formed by the screw body. One end of the screw body is screwed to the fixing nut, and the other end of the screw body is inserted into the elastic base, so that the foaming adhesive forms a foaming adhesive layer around the elastic base through the hollow cavity.

[0010] Optionally, the elastic base has a flow guiding cavity, a flow guiding groove, and a side interface. The flow guiding cavity is connected to the hollow cavity, the flow guiding groove is located on the bottom surface of the elastic base, and the flow guiding groove is connected to the discharge end of the hollow cavity to form a foamed adhesive layer. The side interface is located on the side of the elastic base to allow the hollow adjustment screw to be inserted from the side.

[0011] Optionally, the cross-section of the hollow cavity includes an angle, a rectangle, a pentagon, a hexagon, and an octagon.

[0012] Optionally, the falcon-shaped substrate includes multiple composite substrates, with adjacent composite substrates joined together by a falcon-shaped structure.

[0013] Secondly, this application also provides a construction method for a dry flooring system, the method being implemented using the dry flooring system described in the first aspect, the method comprising:

[0014] Drill holes in the elevated floor panel and insert N hollow support components to obtain a support unit;

[0015] The support unit is placed on the ground and leveled to obtain a flat support unit;

[0016] Foaming adhesive is injected into N hollow support components to fix the hollow support components. Then, the tenon-shaped structural substrate is glued to the surface of the flat support unit, and the flatness of the tenon-shaped structural substrate is adjusted to obtain a flat tenon-shaped structural substrate.

[0017] The floor covering layer is bonded to the surface of the flat tenon structure substrate to form a finishing unit, thereby obtaining a dry flooring system;

[0018] Where N≥4 and N is a positive integer.

[0019] Optionally, placing the support unit on the ground and leveling it to obtain a flat support unit specifically includes:

[0020] Rotate the support unit until N hollow support components contact the ground, then adjust the height of the four hollow support components at the corners of the elevated floor panel until the four hollow support components abut the ground to obtain a preliminary horizontal support unit;

[0021] Adjust N-4 of the hollow support components until they abut against the ground to obtain the flat support unit to be tested;

[0022] The flatness of the flat support unit to be tested is detected;

[0023] Based on the flatness of the flat support unit to be tested, determine whether it is necessary to readjust N-4 hollow support components again;

[0024] If so, fix the flat support unit to be tested to obtain the flat support unit;

[0025] Where N≥4 and N is a positive integer.

[0026] Optionally, based on the flatness of the flat support unit to be tested, it is determined whether it is unnecessary to readjust the N-4 hollow support components, specifically including:

[0027] By comparing the flatness of the flat support unit to be tested with the standard flatness, it is determined whether it is necessary to readjust N-4 hollow support components again.

[0028] If the flatness of the flat support unit to be tested is within the standard flatness range, then the flat support unit to be tested is fixed to obtain the flat support unit.

[0029] If the flatness of the flat support unit to be tested is outside the standard flatness range, then readjust N-4 of the hollow support components and judge again.

[0030] The standard flatness is 2mm.

[0031] Optionally, the flatness of the falcon-shaped structural substrate is ≤2mm; the splicing gap between two adjacent falcon-shaped structural substrates is ≤0.5mm.

[0032] The technical solutions provided in this application have the following advantages compared with the prior art:

[0033] This application provides a dry flooring system that differs from traditional rigid contact between floor nails or bolts and the ground. Instead, it uses a foam adhesive layer to fix the hollow support components to the ground, resulting in a stronger bond while avoiding a rigid connection. This ensures that the raised floor panel, fixed to the hollow self-supporting components, remains parallel to the ground, guaranteeing the flatness of the raised floor panel. Furthermore, a tenon-and-mortise structure substrate is introduced between the floor covering layer and the raised floor panel. Since the floor covering layer is generally flexible, direct bonding to the raised floor panel would result in an uneven surface. Therefore, by introducing the mortise and tenon structure substrate, the mortise and tenon structure in the substrate can be used to perform secondary leveling of the ground system, thereby making the floor mat surface layer flat. Then, by introducing the first adhesive layer and the second adhesive layer respectively, the mortise and tenon structure substrate and the raised floor panel can be firmly bonded together. This ensures the flatness of the mortise and tenon structure substrate on the basis of the flatness of the raised floor panel. The second adhesive layer can not only fill the gaps in the mortise and tenon structure in the mortise and tenon structure substrate, but also make the bond between the floor mat surface layer and the mortise and tenon structure substrate firmly bonded, thereby further ensuring the flatness of the floor mat surface layer, and thus achieving a dry floor system with high flatness.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this application can be purchased from the market or prepared by existing methods.

[0046] like Figure 1 As shown in the figure, this application provides a dry ground system, the ground system comprising:

[0047] Support unit 1, the support unit 1 includes an elevated ground panel 11, a hollow support assembly 12 and a foam adhesive layer 13, one end of the support bolt abuts the ground, the foam adhesive layer 13 is provided between the hollow support assembly 12 and the ground, and the other end of the hollow support assembly 12 is fixedly connected to the elevated ground panel 11 so that an installation space is formed between the elevated ground panel 11 and the ground;

[0048] The finishing unit 2 includes a first adhesive layer 21, a tenon-shaped structural substrate 22, a second adhesive layer 23, and a floor mat finishing layer 24. One side of the first adhesive layer 21 is fixed to the surface of the raised floor panel 11, and the other side of the first adhesive layer 21 is fixed to the bottom surface of the tenon-shaped structural substrate 22. One side of the second adhesive layer 23 is fixed to the surface of the tenon-shaped structural substrate 22, and the other side of the second adhesive layer 23 is fixed to the bottom surface of the floor mat finishing layer 24.

[0049] In this embodiment of the application, the falcon-shaped substrate refers to a series of combined substrates that are connected by a snap-fit ​​method such as a sub-groove structure substrate and a mother groove structure substrate through a locking or flat snap-fit ​​connection.

[0050] In some optional embodiments, the hollow support assembly 12 includes a fixing nut 121, a hollow adjusting screw 122, and an elastic base 123. The fixing nut 121 is fixed to the side of the raised floor panel 11. One end of the hollow adjusting screw 122 is screwed into the fixing nut 121, and the other end of the hollow adjusting screw 122 is inserted into the elastic base 123. The elastic base 123 is disposed against the ground, and the foam adhesive layer 13 is provided around the elastic base 123 to achieve flexible contact between the hollow support assembly 12 and the ground.

[0051] In this embodiment, the hollow support component 12 is controlled by using a fixing nut 121 and a hollow adjusting screw 122 to effectively adjust the height of the hollow support component 12, thereby adjusting the distance between the raised floor panel 11 and the ground, making the ground and the raised floor panel 11 flat. Furthermore, the elastic base 123 can effectively replace the traditional method of directly inserting ground nails or bolts into the ground, allowing the hollow support component 12 to make flexible contact with the ground. This not only facilitates the adjustment of the height of the raised floor panel 11, but also, together with the foam adhesive layer 13, prevents the hollow support component 12 from fraying, thereby improving the support strength of the raised floor panel 11.

[0052] In some optional embodiments, the adjusting screw includes a screw body 1221 and a hollow cavity 1222 formed by the screw body 1221. One end of the screw body 1221 is screwed to the fixing nut 121, and the other end of the screw body 1221 is inserted into the elastic base 123, so that the foaming adhesive forms a foaming adhesive layer 13 around the elastic base 123 through the hollow cavity 1222.

[0053] In this embodiment of the application, by introducing a hollow cavity 1222 into the hollow adjusting screw 122, the foam adhesive can be injected through the hollow cavity 1222, thereby forming the foam adhesive layer 13.

[0054] In some optional embodiments, the elastic base 123 has a flow guiding cavity 1231, a flow guiding groove 1232, and a side interface 1233. The flow guiding cavity 1231 is connected to the hollow cavity 1222. The flow guiding groove 1232 is located on the bottom surface of the elastic base 123 and is connected to the discharge end of the hollow cavity 1222 to form a foam adhesive layer 13. The side interface 1233 is located on the side of the elastic base 123 to allow the hollow adjusting screw 122 to be inserted from the side.

[0055] In this embodiment, by providing a flow guide cavity 1231, a flow guide groove 1232, and a side interface 1233 on the elastic base 123, the side interface 1233 is used to allow the hollow adjusting screw 122 to be inserted into the elastic base 123, avoiding the instability of the hollow adjusting screw 122 caused by direct insertion and removal. The flow guide cavity 1231 is used in conjunction with the hollow cavity 1222 to quickly discharge the expanding foam, and the flow guide groove 1232 is used to achieve effective distribution of the expanding foam on the bottom surface of the elastic base 123, thereby enabling the expanding foam adhesive layer 13 to be formed quickly.

[0056] In some alternative embodiments, the cross-section of the hollow cavity 1222 includes an angle, a rectangle, a pentagon, a hexagon, and an octagon.

[0057] In this embodiment, the specific composition of the cross-section of the hollow cavity 1222 is controlled to cover the shape of most of the adjustment tools actually used. This allows not only the introduction of expanding foam through the hollow cavity 1222, but also the adjustment between the hollow adjusting screw 122 and the fixing nut 121, enabling the hollow support assembly 12 to be adjusted in height more conveniently.

[0058] In some alternative embodiments, the falcon-shaped substrate 22 includes a plurality of combined substrates, with adjacent combined substrates joined together by a falcon-shaped structure.

[0059] In this embodiment of the application, by controlling the specific composition of the falcon-shaped structural substrate 22, the falcon-shaped structure can not only ensure the bonding strength of the falcon-shaped structural substrate 22, but also adjust the flatness of the falcon-shaped structural substrate 22 in a secondary manner through the multi-directional cooperation between the falcon-shaped structures, thereby ensuring the flatness of the subsequent floor mat finish layer 24.

[0060] like Figure 3 As shown, based on a general inventive concept, this application also provides a construction method for a dry flooring system, the method being implemented using the dry flooring system described in the first aspect, the method comprising:

[0061] S1. Drill holes in the elevated floor panel 11 and insert N hollow support components 12 to obtain support unit 1;

[0062] S2. Place the support unit 1 on the ground and level it to obtain a flat support unit 1;

[0063] S3. Foaming adhesive is injected into N hollow support components 12 to fix the hollow support components 12. Then, the tenon structure substrate 22 is glued to the surface of the flat support unit 1, and the flatness of the tenon structure substrate 22 is adjusted to obtain the flat tenon structure substrate 22.

[0064] S4. The floor covering layer 24 is bonded to the surface of the flat tenon structure substrate 22 to form the covering unit 2, thereby obtaining a dry floor system;

[0065] Where N≥4 and N is a positive integer.

[0066] This construction method is based on the above-mentioned dry ground system. The specific steps of this construction method can be referred to the above embodiments. Since this construction method adopts some or all of the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0067] In this embodiment, by first leveling the support unit 1, then fixing the hollow adjusting screw 122 and fixing nut 121 inside the hollow support assembly 12 with expanding foam, and quickly forming the expanding foam adhesive layer 13 on the bottom surface of the elastic base 123, the support unit 1 and the ground can be stably bonded. Then, the dry flooring system is leveled a second time using the falcon-shaped structural substrate 22, thereby improving the overall flatness of the dry flooring system through two leveling operations.

[0068] The number of corresponding hollow support components 12 can be determined by the shape of the elevated ground panel 11. Since the commonly used shape of the elevated ground panel 11 is a triangle, rectangle or other polygon, the number of corresponding hollow support components 12 can be 3 or more.

[0069] In some optional embodiments, placing the support unit 1 on the ground and leveling it to obtain a flat support unit 1 specifically includes:

[0070] S21. Rotate the support unit 1 until N hollow support components 12 are in contact with the ground, then adjust the height of the four hollow support components 12 at the corners of the elevated ground panel 11 until the four hollow support components 12 abut against the ground to obtain a preliminary horizontal support unit 1;

[0071] S22. Adjust N-4 hollow support components 12 until N-4 hollow support components 12 abut against the ground to obtain the flat support unit 1 to be tested;

[0072] S23. Detect the flatness of the flat support unit 1 to be tested;

[0073] S24. Based on the flatness of the flat support unit 1 to be tested, determine whether it is not necessary to adjust the N-4 hollow support components 12 again;

[0074] If so, fix the flat support unit 1 to be tested to obtain the flat support unit 1;

[0075] Where N≥4 and N is a positive integer.

[0076] In this embodiment of the application, by refining the specific leveling method of the support unit 1, by first adjusting the four hollow support components 12 at the corners of the elevated ground panel 11, and then adjusting the remaining hollow support components 12, the flatness of the support unit 1 can be guaranteed.

[0077] In some alternative implementations, such as Figure 7 As shown, based on the flatness of the flat support unit 1 to be tested, it is determined whether it is necessary to readjust the N-4 hollow support components 12. Specifically, this includes:

[0078] S241. Based on the comparison between the flatness of the flat support unit 1 to be tested and the standard flatness, determine whether it is not necessary to adjust N-4 hollow support components 12 again;

[0079] If the flatness of the flat support unit 1 to be tested is within the range of standard flatness, then the flat support unit 1 to be tested is fixed to obtain the flat support unit 1.

[0080] If the flatness of the flat support unit 1 to be tested is outside the standard flatness range, then readjust N-4 of the hollow support components 12 and judge again.

[0081] The standard flatness is 2mm.

[0082] In this embodiment of the application, by detecting and judging the flatness of the flat support unit 1 to be tested, the overall flatness of the support unit 1 can be guaranteed, thereby ensuring the flatness of the floor mat surface layer 24.

[0083] In some optional embodiments, the flatness of the falcon-shaped structural substrate 22 is ≤2mm; the splicing gap between two adjacent falcon-shaped structural substrates 22 is ≤0.5mm.

[0084] In this embodiment of the application, the positive effect of controlling the flatness of the falcon-shaped structural substrate 22 to be ≤2mm is that by controlling the specific flatness of the falcon-shaped structural substrate 22, not only can the error in the second leveling stage be maintained within the height range of 1mm, but the flatness of the floor mat finish layer 24 after the second leveling can also be maintained below 2mm.

[0085] The positive effect of controlling the splicing gap between two adjacent falcon-shaped structural substrates 22 to be ≤0.5mm is that within this splicing gap range, a near-seamless splicing of the falcon-shaped structural substrates 22 can be achieved.

[0086] The present application is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the application. Experimental methods in the following embodiments that do not specify specific conditions are generally determined according to national standards. If there is no corresponding national standard, then general international standards, conventional conditions, or conditions recommended by the manufacturer are followed.

[0097] Comparing Example 2 with Example 1, the difference between Example 2 and Example 1 is as follows:

[0098] A construction method for a dry floor system includes:

[0099] S1. Drill holes in the overhead floor panel 11 and insert N hollow support components 12 to obtain support unit 1;

[0100] S21. Rotate the support unit 1 until N hollow support components 12 are in contact with the ground, then adjust the height of the four hollow support components 12 at the corners of the overhead ground panel 11 until the four hollow support components 12 touch the ground to obtain a preliminary horizontal support unit 1.

[0104] If the flatness of the flat support unit 1 to be tested is within the standard flatness range, then fix the flat support unit 1 to be tested to obtain the flat support unit 1.

[0105] If the flatness of the flat support unit 1 to be tested is outside the standard flatness range, then readjust N-4 hollow support components 12 and judge again.

[0109] Where N≥4 and N is a positive integer.

[0110] The flatness of the spar structure substrate 22 is ≤2mm; the splicing gap between two adjacent spar structure substrates 22 is ≤0.5mm.

[0111] Example 3

[0112] Comparing Example 3 and Example 2, the differences between Example 3 and Example 2 are as follows:

[0113] The specific process of the construction method is as follows:

[0114] 1. Elevation height

[0115] Confirm the location and height of the 1-meter line, and use the 1-meter line drawn on the interior drawings as a guide for construction. When installing a dry flooring system, pay attention to reserving the height of the finishing surface.

[0116] 2. Assembly and laying of elevated ground panel 11

[0117] (1) Tighten the fixing nut 121 to the reserved hole on the back of the raised floor panel 11 with an electric wrench. The embedded end of the fixing nut 121 should be seamless with the panel. After the fixing nut 121 is fully inserted, stop applying force immediately to avoid damage to the hole and loosening of the connection.

[0118] (2) Install the hollow adjusting screws 122 onto the fixing nuts 121 using a hand drill. The hollow adjusting screws 122 at the four corners of the raised floor panel 11 should be significantly higher than the hollow adjusting screws 122 at other positions to form the support unit 1.

[0119] (3) Lift the assembled support unit 1 to the installation position and place it down smoothly. When placing the plate, do not let one end of the hollow adjusting screw 122 bear the weight on the ground. All four corners should land simultaneously.

[0120] (4) Before laying and placing the support unit 1, the laying position should be cleaned with a brush to remove dust again, so as not to affect the bonding strength after the foaming adhesive is injected.

[0121] (5) After the support unit 1 is placed in place, use a right angle ruler to stand at the four corners of the raised floor panel 11 in sequence. According to the horizontal line of the infrared level, use an Allen wrench to adjust the four corners of the panel to be horizontal and the height to meet the requirements. Then adjust the horizontal and height of the middle position to ensure that all hollow adjustment screws 122 are on the ground.

[0122] (6) When different overhead ground panels 11 are connected to each other, the adjacent corners must be at the same height and there should be no obvious height difference.

[0123] (7) Each time the infrared level changes position, the 1-meter line should be recalibrated and checked to ensure that it is consistent with the height and level of the overhead floor panel 11 laid in front, so as to ensure that the overall height and level are the same. When two infrared levels are used at the same time, they should be mutually calibrated.

[0124] (8) For raised floor panels 11, if there are problems with the horizontal and vertical alignment of the walls, doorways, corners, etc., the gaps should generally not exceed 10mm.

[0125] (9) For the raised floor panel 11 that needs to be sawed and drilled, the actual measured dimensions should be accurately marked, and the cut of the raised floor panel 11 should be straight (note the reserved size, generally 2mm smaller than the actual size).

[0126] (10) The number of openings in the sawed overhead floor panel 11 should be increased according to the actual situation, and hollow support components 12 should be added to ensure the overall ground strength.

[0127] (11) If the landing point of the hollow support component 12 coincides with the pipeline, the distance between the overlapping points should be measured, and the hollow support component 12 should be installed by opening a hole on the overhead floor panel 11 at the position away from the pipeline. The number of hollow support components 12 should be increased as needed to ensure the overall strength.

[0128] (12) The number of anchor bolts for extra-large overhead floor panels 11 should be increased according to the actual situation.

[0129] (13) During the laying process, the front and rear overhead floor panels 11 should be checked continuously.

[0130] (14) When fine-tuning, use an Allen wrench to adjust the height of the hollow adjusting screw 122, and use a spirit level and infrared level to check to ensure that all hollow adjusting screws 122 are fully in place and not loose.

[0131] (15) After meeting the qualification requirements, start injecting glue. Inject about 3mL of glue into the hollow cavity 1222 of each hollow adjusting screw 122. Stop injecting glue when the glue is level with the surface of the raised floor panel 11. Do not miss any glue injection points. Other un-injected holes should be protected from dust. If necessary, cover them with tape.

[0132] Example 4

[0133] Comparing Example 4 and Example 3, the differences between Example 4 and Example 3 are as follows:

[0134] 3. Mounting of the Hayabusa structural substrate 22:

[0135] (1) After the glue is applied, fix the flat support unit 1.

[0136] (2) Apply a layer of adhesive to the surface of the flat support unit 1. Note that after the adhesive is applied, it should be scraped to make the adhesive adhere evenly to the surface of the overhead floor panel 11 of the support unit 1.

[0137] (3) By splicing two falcon-shaped structural base plates 22 together to form a falcon-shaped structural base plate 22, it is placed on the surface of the raised floor panel 11. After gluing, while the adhesive is still wet, the levelness of the falcon-shaped structural base plate 22 is checked using a level and an infrared level. The flatness of the falcon-shaped structural base plate 22 is adjusted by adjusting the interlocking gap of the letter buckle structure between the two falcon-shaped structural base plates 22, so that its flatness is within 1mm.

[0138] (4) After the falcon-shaped structural substrate 22 and the overhead ground panel 11 are firmly bonded, apply adhesive to the surface of the falcon-shaped structural substrate 22. Note that after the adhesive is applied, it should be scraped to ensure that the adhesive adheres evenly to the surface of the falcon-shaped structural substrate 22.

[0139] (5) While the adhesive is still wet, the finished floor covering layer 24 is then applied to the surface of the spar structure substrate 22 to form a dry floor system.

[0141] Comparative Example 1 and Example 4 will be compared. The difference between Comparative Example 1 and Example 4 is as follows:

[0143] Comparative Example 2

[0144] Comparative Example 2 and Example 4 will be compared. The difference between Comparative Example 2 and Example 4 is as follows:

[0146] Comparative Example 3

[0147] Comparing Comparative Example 3 and Example 4, the differences between them are as follows:

[0148] Instead of using the falcon-shaped structural substrate 22, the raised floor panel 11 and the floor mat finish layer 24 are directly bonded together.

[0152] Detailed analysis in Table 1:

[0153] Smoothness refers to the surface flatness of the resulting dry floor system. The lower the smoothness, the smoother the dry floor system.

[0154] From the data of Example 4, Comparative Example 1, and Comparative Example 2, it can be seen that:

[0155] The flatness of the raised floor panel 11 is ensured by fixing the hollow support component 12 to the ground with a foam adhesive layer 13. Then, a tenon-shaped structural substrate 22 is introduced between the floor covering layer 24 and the raised floor panel 11. The tenon-shaped structure in the tenon-shaped structural substrate 22 is used to perform secondary leveling of the ground system, thereby making the floor covering layer 24 flat. Then, a first adhesive layer 21 and a second adhesive layer 23 are introduced to further ensure the flatness of the floor covering layer 24, thus achieving a dry floor system with high flatness.

[0156] One or more technical solutions in the embodiments of this application have at least the following technical effects or advantages:

[0157] (1) The dry floor system provided in this application provides a method to fix the hollow support component 12 and the ground with a foam adhesive layer 13 to ensure the flatness of the raised floor panel 11. Then, a tenon structure substrate 22 is introduced between the floor covering layer 24 and the raised floor panel 11. The tenon structure in the tenon structure substrate 22 is used to perform secondary leveling of the floor system, thereby making the floor covering layer 24 flat. Then, a first adhesive layer 21 and a second adhesive layer 23 are introduced to further ensure the flatness of the floor covering layer 24, thereby achieving a dry floor system with high flatness.

[0158] (2) The dry ground system provided in this application uses a hollow support component 12 on the bottom surface of the overhead ground panel 11 and a hollow adjusting screw 122 with point support combined with an elastic base 123. The elastic base 123 buffers the pressure on the hollow adjusting screw 122, thereby automatically leveling the flatness of the structural ground.

[0159] (3) The dry floor system provided in this application embodiment has a through-hole hollow support component 12 that can be injected with glue to ensure that the raised floor panel 11 material-fixing nut 121-shock damping pad-central control adjustment screw-structure floor form a stable geometry, which is stable for a long time, without abnormal noise, hollow feeling, and shaking.

[0160] (4) The dry ground system provided in this application embodiment can not only realize pipeline separation and open inspection ports for easy maintenance, but also adopts a completely dry operation, allowing for immediate occupancy after installation, with high installation efficiency and convenient leveling.

[0161] (5) The dry floor system provided in this application embodiment can be leveled twice by adopting the tenon structure of the tenon structure substrate 22 to ensure that the flatness meets the requirements of the floor mat surface. Not only can the tenon structure substrate 22 be spliced ​​completely by the tenon structure, and the floor mat has no risk of cracking after the gap is treated, but the tenon structure substrate 22 and the raised floor panel 11 are fixed by the first adhesive layer 21 to ensure that the tenon structure substrate 22 can move laterally, further enhancing the structural stability of the dry floor system.

[0162] (6) The dry flooring system provided in this application uses a spar structure substrate 22 instead of the double-layer structure of balance plate and self-leveling in the prior art. The cost is controllable and it can be directly assembled on the factory production site, which further facilitates the installation.

[0163] (7) The dry flooring system provided in this application embodiment adopts a close-fitting splicing method between the mortise and tenon structural substrates 22. Compared with the direct assembly of the raised floor panels 11, the thickness of the mortise and tenon structural substrates 22 during the use stage is smaller than that of the raised floor panels 11, generally between 3mm and 4mm. Therefore, it is possible to achieve a smaller splicing gap (less than 0.5mm) between the mortise and tenon structural substrates 22, or even to achieve a near-seamless finish. When the PVC soft rubber used in the floor mat 24 is in the flow molding stage, it can avoid the PVC soft rubber from encountering gaps and causing the floor mat 24 to crack. At the same time, since the thickness of the mortise and tenon structural substrates 22 is relatively thin, it is difficult to affect the overall flatness and can inherit the flatness of the raised floor panels 11. Furthermore, since the mortise and tenon structural substrates 22 can also fine-tune the flatness of the overall dry floor, it can further improve the flatness of the dry flooring system.

[0164] (8) The dry floor system provided in this application has a lower number of layers and a reduced thickness of each layer, thus ensuring the indoor headroom and providing better performance.

[0165] (9) The dry floor system preparation method provided in this application uses a large amount of simple substrates, such as wood or plastic boards, which have less carbon emissions than the cement and mixing agents required for self-leveling, and can further reduce carbon dioxide emissions.
