Description

Technical Field

[0001] This application relates to the field of elevated ground system technology, and in particular to a lightweight assembled elevated ground system. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Because prefabricated construction is fast and can be mass-produced, the overall production cost is lower. It is currently widely used in new housing, renovations, apartments, hotels, medical facilities, and other projects. Prefabricated dry-process flooring is a major component of prefabricated construction. This type of flooring typically requires a decorative finish, currently the most popular being ceramic tiles or stone. To achieve a beautiful and grand finish, the size of the tiles or stone is often made as large as possible. However, because prefabricated dry-process flooring is a modular assembly, the unevenness and gaps between different modules can easily cause the tiles or stone to crack when combined with large-sized tiles or stone.

[0003] To address the issue of cracking in the surface layer of tiles or stone, rigid calcium silicate balancing boards are typically used in prefabricated dry-process flooring. The high density and flatness of calcium silicate effectively improve the flatness between different modules of the prefabricated dry-process flooring, while also reducing gaps, thus preventing cracking of the surface layer of tiles or stone. However, large-format calcium silicate balancing boards are generally 8mm to 10mm thick, and due to their high density, individual boards are difficult to handle and easily damaged. Furthermore, gaps and noticeable height differences still exist when splicing calcium silicate balancing boards, making it easy for large-format tiles or stone to crack even when using calcium silicate balancing boards.

[0004] Meanwhile, most current prefabricated dry-layout systems rely on support components to abut against the structural floor slab or are rigidly fixed to the concrete floor by nailing. These fixing methods are prone to loosening after prolonged foot traffic and vibration, leading to system instability. This instability further reduces the flatness of the calcium silicate balance board and can cause tiles or stone to crack. Therefore, providing a lightweight prefabricated raised floor system that effectively improves the overall flatness of the system while minimizing gaps between different modules is a pressing technical problem that needs to be solved. Utility Model Content

[0005] This application provides a lightweight prefabricated elevated ground system to solve the technical problems of low flatness of large-size calcium silicate balance boards used in existing prefabricated dry ground systems and gaps between different modules in the prefabricated elevated ground system.

[0006] In a first aspect, this application provides a lightweight prefabricated elevated ground system, which is installed on a concrete floor and includes:

[0007] A support plate, which is disposed above the cement floor;

[0008] A balancing buffer layer is fixedly connected to the surface of the supporting plate, and the balancing buffer layer includes a PET buffer layer and / or a PU buffer layer;

[0010] Adhesive layer; the elastic base is fixedly connected to the cement floor through the adhesive layer;

[0011] A finishing layer is disposed on the surface of the balancing buffer layer.

[0012] Optionally, the thickness of the balancing buffer layer is 4mm to 30mm.

[0013] Optionally, the balancing buffer layer and the supporting plate are fixedly connected by an adhesive layer, the thickness of which is 1mm to 2mm.

[0014] Optionally, the hollow adjusting screw has a screw body and a hollow cavity formed by the screw body, one end of the screw body is threaded to the fixing nut, and the other end of the screw body is inserted into the elastic base.

[0015] Optionally, the elastic base is provided with a flow guiding cavity and a plurality of first flow guiding grooves, the flow guiding cavity being connected to the hollow cavity to realize the flow of adhesive liquid;

[0016] The first guide channel is connected to the guide cavity and is disposed in abutment against the adhesive layer; the first guide channel is evenly distributed in a circle around the center of the elastic base on the bottom surface of the elastic base.

[0017] Optionally, the elastic base is further provided with a side interface, which is located on the side of the elastic base. The side interface and the flow guiding cavity form a flow guiding space. The flow guiding space includes a plurality of second flow guiding grooves, which are disposed on the upper and lower surfaces of the flow guiding space.

[0018] Optionally, the hollow adjusting screw is further provided with a support ring, the screw body and the support ring are fixedly connected, and the support ring can be inserted into the side interface.

[0019] Optionally, the bottom surface of the support ring is provided with a fixing ring along the length direction, and the fixing ring abuts against the bottom surface of the flow guiding space.

[0020] Optionally, the fixing nut includes a fixing threaded ring and a nut housing. The fixing threaded ring is disposed on the top surface of the nut housing and is threadedly connected to the bottom surface of the support plate. The nut housing is threadedly connected to the screw body.

[0021] Optionally, the bottom surface of the elastic base is further provided with elastic anti-slip particles, which abut against the adhesive layer.

[0022] The technical solutions provided in this application have the following advantages compared with the prior art:

[0023] This application provides a lightweight prefabricated raised floor system. Compared to the calcium silicate balancing board used in traditional prefabricated dry floor systems, this system replaces it with a polyethylene terephthalate (PET) or polyurethane (PU) buffer layer. The PET or PU material provides a high strength of over 500 kPa, effectively buffering the pressure on the entire prefabricated raised floor system. This buffer layer also features a flexible, porous structure, allowing for better adhesion of the finish layer and reducing gaps between different modules. This enables large-format finish layers to adhere stably to the buffer layer. A support assembly including a fixing nut, a hollow adjusting screw, and a flexible base is used. The relative sliding between the hollow adjusting screw and the fixing nut adjusts the distance between the support plate and the concrete floor, improving the flatness of the support plate relative to the concrete floor. The flexible base provides flexible contact between the prefabricated raised floor system and the concrete floor. Finally, an adhesive layer compensates for the gaps between the flexible base and slight slopes. The gaps between the concrete surfaces allow the elastic base to deform and solidify, transforming the contact between the elastic base and the concrete surface from a flexible contact to a hybrid of flexible and rigid contact. This replaces the traditional purely rigid contact method of gravity abutment or nailing, increasing the pressure the elastic base can withstand and thus comprehensively improving the overall flatness of the support plate. Consequently, the balance buffer layer, which is fixedly connected to the support plate, can also have better flatness. Therefore, by using a balance buffer layer including a PET buffer layer and / or a PU buffer layer, along with support components including fixing nuts, hollow adjusting screws, and an elastic base, the flatness of the balance buffer layer can be comprehensively improved to better distribute the actual force during the assembly of the raised floor system. At the same time, the high strength and flexible porous structure of the balance buffer layer can effectively reduce the force changes in the four directions of the balance buffer layer, allowing large-format finishing layers to adhere tightly to the balance buffer layer and reducing the gap width between different finishing layers. This improves the overall flatness of the assembled raised floor system while minimizing the gaps between different modules of the assembled raised floor system. Attached Figure Description

[0040] like Figure 1 and Figure 3 As shown, this application embodiment provides a lightweight prefabricated elevated ground system, which is installed on a cement floor 1. The prefabricated elevated ground system includes:

[0041] Support plate 2, which is disposed above the cement floor 1;

[0042] A balancing buffer layer 3 is fixedly connected to the surface of the support plate 2. The balancing buffer layer 3 includes a PET buffer layer 31 and / or a PU buffer layer 32.

[0043] Support component 4 includes a fixing nut 41, a hollow adjusting screw 42, and an elastic base 43. The fixing nut 41 is fixed to the bottom surface of the support plate 2. One end of the hollow adjusting screw 42 is threaded to the fixing nut 41, and the other end of the hollow adjusting screw 42 is inserted into the elastic base 43.

[0044] Adhesive layer 5, the elastic base 43 is fixedly connected to the cement floor 1 through the adhesive layer 5;

[0045] Finishing layer 7 is disposed on the surface of the balancing buffer layer 3.

[0046] In some alternative embodiments, the thickness of the balancing buffer layer 3 is 4 mm to 30 mm.

[0047] In this embodiment, the specific thickness of the balancing buffer layer 3 is controlled. On the one hand, the PET or PU material within this thickness range has sufficient strength to effectively support the weight of the stone or tile in the large-format decorative layer 7 and reduce the risk of pitting deformation and collapse of the balancing buffer layer 3. On the other hand, this thickness range can make the force on the supporting plate 2 uniform and also play a certain buffering role. Furthermore, it can reduce the width of the gap between the balancing buffer layers 3 before different modules are assembled into the elevated floor system through elastic contact, thereby improving the flatness of the decorative layer 7 in the assembled elevated floor system and reducing the gap between different modules in the assembled elevated floor system, and avoiding the risk of large-format tile decoration cracking.

[0048] It should be noted that the balancing buffer layer 3 and the supporting plate 2 can be fixed by nailing or by adhesive.

[0049] Meanwhile, since the balance buffer layer 3 is made of PET buffer layer 311 or PU buffer layer 312, the characteristics of polyethylene terephthalate or polyurethane materials determine that the balance buffer layer 3 has the characteristics of high strength and flexible porous structure.

[0050] The thickness of the balancing buffer layer 3 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, or 30mm.

[0051] It should be noted that, compared to traditional rigid balance boards made of calcium silicate, this balance buffer layer 3 has a lower overall density and is therefore lighter in weight, making it easier to handle. Furthermore, due to its flexibility, this balance buffer layer 3 can prevent damage during handling. Moreover, the material properties of this balance buffer layer 3 allow for better cutting or edge trimming, further improving the flatness of the overall assembled elevated floor system. In contrast, traditional calcium silicate balance boards are difficult to trim edges and easily generate a large amount of dust, affecting the safety of workers.

[0052] It should be noted that since the finishing layer 7 can be assembled in a modular manner, theoretically, two or more types of floor finishing layers 7 can be used for decoration. Furthermore, there are various options for the connection between different floor finishing layers 7 and the balancing buffer layer 3. Therefore, different finishing layers 7 and their combinations with the balancing buffer layer 3 can be selected according to actual customer needs. For example, the finishing layer 7 can be a brittle finishing layer, a flexible finishing layer, a dry-process ceramic tile finishing layer, or a composite structure of at least two of these. The connection methods between different finishing layers 7 can be adhesive bonding, anchoring, insertion, splicing, or a combination of at least two of these methods. The connection method between the finishing layer 7 and the balancing buffer layer 3 can be adhesive bonding.

[0053] In some optional embodiments, the balancing buffer layer 3 and the supporting plate 2 are fixedly connected by an adhesive layer 6, the thickness of which is 1mm to 2mm.

[0054] In this embodiment, an adhesive layer 6 is used to fix the balance buffer layer 3 and the support plate 2, and the specific thickness of the adhesive layer 6 is controlled. On the one hand, the adhesive force of the adhesive layer 6 can be used to completely fix the support plate 2 and the balance buffer layer 3, preventing the support plate 2 from shifting laterally. This makes the flatness of the balance buffer layer 3 and the support plate 2 mutually bound. On the other hand, the adhesive layer 6 can form a certain elastic interface between the balance buffer layer 3 and the support plate 2, which can further disperse the external force on the balance buffer layer 3 to a certain extent. With the subsequent support component 4, the overall flatness of the assembled elevated ground system can be effectively improved.

[0055] It should be noted that the adhesive layer 6 can be formed by continuous adhesive bonding or by intermittent adhesive bonding.

[0056] like Figure 6 As shown, in some optional embodiments, the hollow adjusting screw 42 is provided with a screw body 421 and a hollow cavity 422 formed by the screw body 421. One end of the screw body 421 is threaded to the fixing nut 41, and the other end of the screw body 421 is inserted into the elastic base 43.

[0057] In this embodiment, by refining the specific composition of the hollow adjusting screw 42, the screw body 421 is used as the basic support structure of the support component 4. The hollow cavity 422 formed by the screw body 421 is used to realize the flow of adhesive, thereby forming an adhesive layer 5 between the elastic base 43 and the cement ground 1. The support component 4 is fixed through the adhesive layer 5, thereby making the support plate 2 more stable and improving the overall flatness of the balance buffer layer 3.

[0058] like Figure 6 and Figure 7 As shown, in some optional embodiments, the elastic base 43 is provided with a flow guiding cavity 431 and a plurality of first flow guiding grooves 432, the flow guiding cavity 431 and the hollow cavity 422 are connected to realize the flow of adhesive liquid;

[0059] The first guide channel 432 is connected to the guide cavity 431, and the first guide channel 432 is disposed in abutment against the adhesive layer 5; the first guide channel 432 is evenly distributed in a circle around the center of the elastic base 43 on the bottom surface of the elastic base 43.

[0060] In this embodiment, by setting a first guide channel 432 on the bottom surface of the elastic base 43, the adhesive first flows out through the hollow cavity 422 of the hollow adjusting screw 42 into the guide cavity 431 of the elastic base 43, and then through the first guide channel 432 to guide the adhesive between the elastic base 43 and the ground, thereby forming an adhesive layer 5 of sufficient thickness, so that the elastic base 43 can be firmly bonded to the ground, thereby improving the stability of the overall assembly of the elevated ground system, and making the support plate 2 more flat, thereby improving the flatness of the balance buffer layer 3 and dispersing the actual force during the assembly of the elevated ground system. At the same time, by utilizing the high strength and flexible porous structure of the balance buffer layer 3, the force changes in the four directions of the balance buffer layer 3 (up, down, left, and right) can be effectively reduced, so that the large-size decorative layer 7 can be tightly attached to the balance buffer layer 3 and the gap width between different decorative layers 7 can be reduced, thereby improving the overall flatness of the assembly of the elevated ground system while minimizing the gaps between different modules of the assembly of the elevated ground system.

[0061] like Figure 7 and Figure 8 As shown, in some optional embodiments, the elastic base 43 is further provided with a side interface 433, which is located on the side of the elastic base 43. The side interface 433 and the flow guiding cavity 431 form a flow guiding space. The flow guiding space includes a plurality of second flow guiding grooves 434, which are disposed on the upper and lower surfaces of the flow guiding space.

[0062] In this embodiment, by setting the second guide channel 434 and the side interface 433, the adhesive flowing out of the hollow adjusting screw 42 can not only form an adhesive layer 5 between the elastic base 43 and the cement ground 1 through the first guide channel 432, but also make the hollow adjusting screw 42 and the elastic base 43 firmly bonded through the adhesive in the second guide channel 434 and the side interface 433. This improves the stability between the elastic base 43 and the cement ground 1, and further improves the stability between the hollow adjusting screw 42 and the elastic base 43, thereby improving the overall flatness of the support plate 2. This can improve the flatness of the balance buffer layer 3 and distribute the actual force during the assembly of the elevated ground system.

[0063] In some alternative embodiments, the hollow adjusting screw 42 is further provided with a support ring 423, the screw body 421 and the support ring 423 are fixedly connected, and the support ring 423 can be inserted into the side interface 433.

[0064] In some optional embodiments, the bottom surface of the support ring 423 is provided with a fixing ring 4231 along the length direction. The fixing ring 4231 abuts against the bottom surface of the flow guiding space. The fixing ring 4231 has flow guiding holes 4232, which are evenly distributed circumferentially on the fixing ring 4231.

[0065] In this embodiment, by setting a support ring 423 on the hollow adjusting screw 42 and then setting a fixing ring 4231 on the support ring 423, an overflow area of ​​a certain size can be formed between the support ring 423 and the guide space, allowing excess adhesive to solidify in this area. This strengthens the bond between the support ring 423 and the elastic base 43, thereby improving the stability between the hollow adjusting screw 42 and the elastic base 43 and enhancing the stability of the support assembly 4. This improves the overall flatness of the support plate 2, thereby improving the flatness of the balance buffer layer 3 and dispersing the actual stress during the assembly of the elevated ground system.

[0066] In some alternative embodiments, the fixing nut 41 includes a fixing threaded ring 411 and a nut housing 412. The fixing threaded ring 411 is disposed on the top surface of the nut housing 412. The fixing threaded ring 411 is threadedly connected to the bottom surface of the support plate 2. The nut housing 412 is threadedly connected to the screw body 421.

[0067] In this embodiment, the nut housing 412 is fixed to the bottom surface of the support plate 2 by fixing the threaded ring 411, and the hollow adjusting screw 42 can be adjusted up and down by the nut housing 412, so that the support assembly 4 can further maintain the flatness of the support plate 2, thereby improving the flatness of the balance buffer layer 3 and dispersing the actual force during the assembly of the elevated ground system.

[0068] like Figure 9 As shown, in some optional embodiments, the bottom surface of the elastic base 43 is further provided with elastic anti-slip particles 435, which abut against the adhesive layer 5.

[0069] In this embodiment, by providing elastic anti-slip particles 436 on the bottom surface of the elastic base 43, the elastic base 43 can be stabilized in the early stage of adhesive injection, and the contact area between the elastic base 43 and the adhesive layer 5 can be increased during the formation of the adhesive layer 5, making the hollow adjusting screw 42 more stable and improving the stability of the support component 4, thereby improving the overall flatness of the support plate 2, and further improving the flatness of the balance buffer layer 3 and dispersing the actual force during the assembly of the elevated ground system.

[0070] 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.

[0109] In summary, the lightweight prefabricated raised floor system provided in this application, compared to the calcium silicate balance board used in traditional prefabricated dry floor systems, replaces it with a polyethylene terephthalate (PET) or polyurethane (PU) buffer layer 3. The buffer layer 3, formed from PET or PU materials, possesses a high strength exceeding 500 kPa, effectively buffering the pressure on the entire prefabricated raised floor system. Furthermore, this buffer layer 3 has a flexible, porous structure, allowing for better adhesion to the finishing layer 7. Simultaneously, it can reduce the gaps between different modules of the elevated ground system, allowing the large-format decorative layer 7 to be stably attached to the balancing buffer layer 3. Furthermore, a support assembly 4, including a fixing nut 41, a hollow adjusting screw 42, and an elastic base 43, is used. The relative sliding between the hollow adjusting screw 42 and the fixing nut 41 allows for adjustment of the distance between the support plate 2 and the concrete floor 1, improving the flatness of the support plate 2 relative to the concrete floor 1. The elastic base 43 then enables flexible contact between the assembled elevated ground system and the concrete floor 1. Finally, the adhesive layer 5 compensates for the gaps between the elastic base 43 and minor slopes. The gap between the elastic base 43 and the cement floor 1 allows the elastic base 43 to deform and solidify, changing the contact between the elastic base 43 and the cement floor 1 from a flexible contact to a mixed contact of flexible and rigid contact. This replaces the traditional purely rigid contact method of gravity abutment or nailing, and increases the pressure that the elastic base 43 can withstand. This, in turn, improves the overall flatness of the support plate 2, allowing the balance buffer layer 3, which is fixedly connected to the support plate 2, to have better flatness. Therefore, the balance buffer layer 3, which includes a PET buffer layer 31 and / or a PU buffer layer 32, combined with a solid... The support assembly 4, consisting of the set nut 41, the hollow adjusting screw 42, and the elastic base 43, can comprehensively improve the flatness of the balance buffer layer 3 to better distribute the actual force during the assembly of the elevated ground system. At the same time, by utilizing the high strength and flexible porous structure of the balance buffer layer 3, the force changes in the four directions of the balance buffer layer 3 (up, down, left, and right) can be effectively reduced, allowing the large-format decorative layer 7 to be tightly attached to the balance buffer layer 3 and reducing the gap width between different decorative layers 7. Thus, while improving the overall flatness of the assembled elevated ground system, the gaps between different modules of the assembled elevated ground system can be minimized.
