Description

Technical Field

[0001] The present application relates to the technical field of floor decoration, and in particular to a portable dry floor heating system. Background Art

[0002] At present, the practices for floor heating systems are roughly divided into traditional floor heating and dry floor heating. Among them, traditional floor heating is to pre-bury the electric heating system or water heating pipes in the traditional cement mortar floor, block the downward transfer of heat through extruded board (XPS), and then use solidified cement mortar to ensure the laying of heat. However, this setting method is difficult to retain heat due to the good thermal conductivity of cement mortar. At the same time, the uneven heating of cement mortar will easily cause hollowing and cracking, which will inevitably affect the appearance of the floor finishing layer. Therefore, at this stage, dry floor heating is generally used for electric heating or water heating. Dry floor heating uses extruded board material or polystyrene foam (EPS) material as the base material, and opens grooves in which the electric heating system or water heating pipes can be buried, and then composite aluminum foil on the base material to allow the heat of the electric heating system or water heating system to transfer upward, but some heat will still inevitably come into contact with the cement mortar floor, thereby affecting the service life of the cement mortar floor.

[0003] Therefore, in order to further avoid uneven heating of cement mortar floors, dry floor heating is generally combined with prefabricated dry floors to form a prefabricated dry floor heating system. This type of heating system first forms a basic dry floor system by setting supporting components between the board and the floor, and then adds a heating structure including a base material layer and a finishing layer to the dry floor system to form a prefabricated heating dry floor system, which can avoid the shortcomings of cement mortar floor operations. However, due to the low melting point of XPS material or EPS material (generally 60℃~70℃), the electric heating system generates heat quickly and at high temperatures, while the water heating system generates heat slowly but at high temperatures, which leads to the risk of collapse of materials in dry floor heating. In addition, the external pressure-bearing capacity of XPS material and EPS material is poor, and they are easily deformed under the action of external force. Therefore, after the decorative tiles or floor tiles are laid on the composite aluminum foil above the substrate, they are easily compressed, resulting in deformation of the overall assembled dry floor heating system. In order to avoid excessive deformation and collapse, the XPS material is restricted by the production process so that its thickness cannot be less than 25mm during use. At the same time, the height of the supporting components of the assembled dry floor heating system generally reaches 10mm~50mm, which will greatly reduce the height space of indoor floor decoration. Moreover, the maximum pressure of EPS material can reach 500kPa, and it is difficult to improve the strength of the material. Therefore, a higher thickness than XPS material is required, which will greatly reduce the height space of indoor floor decoration.

[0004] Therefore, how to provide a portable dry floor heating system to reduce the overall thickness of the substrate layer and increase the floor height space of the assembled dry floor heating system is a technical problem that urgently needs to be solved. Utility Model Content

[0023] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0024] A portable dry floor heating system provided in an embodiment of the present application is compared with a conventional assembled dry floor heating system using XPS material or EPS material as a substrate layer. By replacing the substrate layer with a polyethylene terephthalate (PET) substrate layer or a polyurethane (PU) substrate layer, the substrate layer formed by the PET material or the PU material can have a high strength of more than 500 kPa and a high melting point of about 250°C. The preparation process can control the thickness of the substrate layer to be below 25 mm. The substrate layer can be used to effectively reduce the thickness of the existing XPS material or EPS material substrate layer, thereby effectively reducing the risk of collapse of the substrate layer caused by overheating of electric heating or water heating. At the same time, the characteristics of high strength and high melting point ensure that the thickness of the substrate layer will not change due to heat during the normal working stage of the heating system, and the strength of the supporting plate will not decay. A supporting assembly including a fixing nut, a hollow adjusting screw and an elastic base is used. The distance between the supporting plate and the cement floor can be adjusted by the relative sliding between the hollow adjusting screw and the fixing nut, so that the entire heating system is stable. The elastic base realizes flexible contact between the heating system and the cement floor, and finally the gap between the elastic base and the cement floor with a small slope is filled by the adhesive layer. At the same time, the deformation of the elastic base is solidified and formed, and the contact mode between the elastic base and the cement floor is changed from flexible contact to a mixed contact mode of flexible contact and rigid contact, thereby increasing the pressure that the elastic base can withstand, and then improving the overall flatness of the supporting plate, so that the substrate layer fixedly connected to the supporting plate can have better flatness, and is not easy to deform when subjected to strong external force, and further can avoid the risk of deformation and collapse of the substrate layer pits. Therefore, by using the heating layer including the substrate layer and the composite aluminum foil layer, and then in combination with the supporting assembly including the fixing nut, the hollow adjusting screw and the elastic base, the flatness of the substrate layer can be improved and the actual force of the heating process can be dispersed. At the same time, the high strength and high melting point of the substrate layer can be used to effectively reduce the strength change of the substrate layer during the heating stage, and then the internal force and external force state of the substrate layer can be comprehensively improved, so as to reduce the overall thickness of the substrate layer, thereby increasing the floor height space of the prefabricated dry floor heating system.

[0039] like Figures 1 to 4 As shown, the embodiment of the present application provides a portable dry floor heating system, the heating system is arranged on a cement floor 1, and the heating system comprises:

[0040] A supporting plate 2; the supporting plate 2 is arranged above the cement floor 1;

[0041] Heating layer 3; the heating layer 3 includes a substrate layer 31 and a composite aluminum foil layer 32, the top of the PET substrate layer 311 is covered with the composite aluminum foil layer 32, and the bottom of the substrate layer 31 is fixedly connected to the supporting plate 2; a heating channel groove group 33 is provided in the substrate layer 31 to accommodate an electric heating structure or a water heating structure; the substrate layer 31 includes a PET substrate layer 311 and / or a PU substrate layer 312;

[0042] Support assembly 4; the support assembly 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 threadedly connected to the fixing nut 41, and the other end of the hollow adjusting screw 42 is plugged into the elastic base 43 to form an overhead space;

[0043] Adhesive layer 5; the elastic base 43 is fixedly connected to the cement floor 1 through the adhesive layer 5.

[0044] It should be noted that the overhead space formed by the support assembly 4 can accommodate various pipelines, such as the main pipeline of the electric heating structure or the water heating structure, and can also accommodate water pipes and electrical wire pipes, etc., so that the pipelines of the entire heating system can be separated, which facilitates subsequent maintenance work.

[0045] In some optional embodiments, the thickness of the substrate layer 31 is 4 mm to 30 mm.

[0046] In the embodiment of the present application, the specific thickness of the substrate layer 31 is controlled. On the one hand, the PET material or PU material within the thickness range has sufficient strength to facilitate the laying of the heating channel groove group 33 and effectively maintain the heat of the electric heating structure or the water heating structure. On the other hand, the thickness range can make the force on the supporting plate 2 uniform, and can also play a certain buffering role, further improving the flatness of the prefabricated dry floor heating system, and cooperating with saving the clearance of the indoor prefabricated dry floor heating system, thereby increasing the indoor clearance height.

[0047] At the same time, since the substrate layer 31 adopts the PET substrate layer 311 or the PU substrate layer 312, and the characteristics of the polyethylene terephthalate material or the polyurethane material determine that the substrate layer 31 has the characteristics of high strength and high melting point, the substrate layer 31 is not easy to deform during the normal working stage of the electric heating structure or the water heating structure, thereby avoiding the overall strength attenuation of the heating system due to heat. Therefore, compared with the traditional XPS material or EPS material, the thickness of the substrate layer 31 is thinner, so the thickness can be less than 25 mm.

[0048] The thickness of the substrate layer 31 can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 30 mm.

[0049] It should be noted that in order to ensure the thermal stability of the heating system, it is generally necessary to control the thickness of the composite aluminum foil layer 32 to 0.01mm~0.2mm. Within this thickness range, the composite aluminum foil layer 32 can have sufficient thickness to form a thermal insulation layer that isolates the substrate layer 31, thereby preventing the heat of the electric heating pipes or water heating pipes fixed in the heating channel groove group 33 from being diffused, and then cooperating with the substrate layer 31 to improve the overall thermal insulation performance of the heating system.

[0050] The thickness of the composite aluminum foil layer 32 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm or 0.20 mm.

[0051] It should be noted that since electric heating or water heating is arranged in the substrate layer 31, and the material used for the substrate layer 31 is a flexible material PET or PU, which can be formed into a coil. Therefore, in the actual production stage of the substrate layer 31, the electric heating or water heating equipment can be first fixed in the heating channel groove group 33 on which the composite aluminum foil layer 32 is laid to obtain a heating layer 3 containing an electric heating structure or a water heating structure, and then the heating layer 3 is rolled up to form a coil, which saves space, and the coil can be laid out in the final laying stage to reduce on-site construction links.

[0052] In some optional embodiments, the opening of the heating channel groove group 33 is provided at the connection between the substrate layer 31 and the composite aluminum foil layer 32;

[0053] The heating channel grooves in the heating channel groove group 33 are evenly arranged in the base material layer 31 .

[0054] In the embodiment of the present application, by refining the distribution of the heating channel groove group 33, the heating channel grooves of the heating channel groove group 33 can be used to connect the main heating pipes fixed in the overhead space. Since one end of the fixed main heating pipe is directly connected to the heat source, a heating circuit is formed and the normal operation of the heating system is achieved.

[0055] In some optional embodiments, the substrate layer 31 and the supporting plate 2 are fixedly connected via an adhesive layer 6 , and the thickness of the adhesive layer 6 is 1 mm to 2 mm.

[0056] In the embodiment of the present application, the substrate layer 31 and the support plate 2 are fixed by using an adhesive layer 6, and the specific thickness of the adhesive layer 6 is controlled. On the one hand, the bonding force of the adhesive layer 6 can be used to completely fix the support plate 2 and the substrate layer 31, so that the flatness of the substrate layer 31 is bound to the support plate 2. On the other hand, the adhesive layer 6 can form a thermal insulation barrier between the substrate layer 31 and the support plate 2, thereby preventing heat from diffusing into the support plate 2 to a certain extent, and further cooperating with the composite aluminum foil layer 32 to improve the overall thermal insulation performance of the assembled dry floor heating system.

[0057] It should be noted that the adhesive layer 6 can be formed by continuous bonding with glue or by interval bonding with glue dots.

[0058] In some optional embodiments, the heating system further includes a balancing layer 7 and a finishing layer 8 , wherein the balancing layer 7 is fixedly connected to the surface of the composite aluminum foil layer 32 , and the finishing layer 8 is disposed on the surface of the balancing layer 7 .

[0059] In the embodiment of the present application, the balancing layer 7 is first used to balance the surface of the composite aluminum foil layer 32 and then the finishing layer 8 is arranged. On the premise that the supporting plate 2 is flat, an assembled dry floor heating system with better flatness can be obtained.

[0060] The balancing layer 7 can be made of a balancing board or other hard decoration materials.

[0061] It should be noted that, since the finishing layer 8 can be assembled in an assembled manner, the finishing layer 8 can theoretically be decorated with two or more floor finishing layers 8, and there are many different options for the connection relationship between different floor finishing layers 8 and the balancing layer 7. Therefore, according to actual customer needs, different finishing layers 8 and their matching relationships with the balancing layer 7 can be selected; for example, the finishing layer 8 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 the brittle finishing layer, the flexible finishing layer and the dry-process ceramic tile finishing layer; the connection method between the finishing layer 8 and the balancing layer 7 can be bonding, anchoring, insertion, splicing, or a combination of at least two of bonding, anchoring, insertion and splicing.

[0062] like Figure 5 As shown, in some optional embodiments, the hollow adjustment screw 42 is provided with a screw body 421 and a hollow cavity 422 enclosed by the screw body 421, one end of the screw body 421 is threadedly connected to the fixing nut 41, and the other end of the screw body 421 is inserted into the elastic base 43.

[0063] In the embodiment of the present application, by refining the specific composition of the hollow adjustment screw 42, the screw body 421 is used as the basic supporting structure of the support component 4, and the hollow cavity 422 formed by the screw body 421 is used to realize the circulation of glue, so that an adhesive layer 5 can be formed between the elastic base 43 and the cement floor 1, and the support component 4 is fixed by the adhesive layer 5, so that the support plate 2 is more stable, thereby improving the overall flatness of the heating layer 3.

[0064] like Figure 6 and Figure 7 As shown, in some optional embodiments, the elastic base 43 is provided with a guide cavity 431 and a plurality of first guide grooves 432, and the guide cavity 431 is connected to the hollow cavity 422 to achieve the circulation of the glue;

[0065] The first guide groove 432 is connected to the guide cavity 431 , and is disposed against the adhesive layer 5 ; the first guide groove 432 is evenly distributed on the bottom surface of the elastic base 43 in a circle with the center of the elastic base 43 as the center.

[0066] In the embodiment of the present application, a first guide groove 432 is provided on the bottom surface of the elastic base 43, and the glue first flows out through the hollow cavity 422 of the hollow adjusting screw 42 to the guide cavity 431 of the elastic base 43, and then the glue is guided to between the elastic base 43 and the ground through the first guide groove 432, 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 dry floor heating system, and thus making the supporting plate 2 flatter, thereby improving the flatness of the substrate layer 31 and dispersing the actual force during the heating process, and at the same time, utilizing the high strength and high melting point of the substrate layer 31. Highly stable physical and chemical properties can effectively reduce the strength change of the substrate layer 31 during the heating stage, and comprehensively improve the internal and external stress states of the substrate layer 31, thereby reducing the overall thickness of the substrate layer 31, thereby increasing the floor height space of the assembled dry floor heating system.

[0067] In some optional embodiments, the elastic base 43 is further provided with a side interface 433, the side interface 433 is provided on the side of the elastic base 43, the side interface 433 and the guide cavity 431 form a guide space, the guide space includes a plurality of second guide grooves 434, and the second guide grooves 434 are provided on the upper surface and the lower surface of the guide space;

[0068] The hollow adjustment 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 .

[0069] In the embodiment of the present application, by providing a second guide groove 434 and a side interface 433, the glue flowing out of the hollow adjusting screw 42 can not only form a bonding layer 5 between the elastic base 43 and the cement floor 1 through the first guide groove 432, but also can make the hollow adjusting screw 42 and the elastic base 43 firmly bonded through the second guide groove 434 and the side interface 433, which can further improve the stability between the elastic base 43 and the cement floor 1 while further improving the stability between the hollow adjusting screw 42 and the elastic base 43, thereby achieving an improvement in the overall flatness of the supporting plate 2, and further improving the flatness of the substrate layer 31 and dispersing the actual force during the heating process.

[0070] In some optional embodiments, a fixing ring 4231 is provided on the bottom surface of the support ring 423 along the length direction, the fixing ring 4231 abuts against the bottom surface of the guide space, and the fixing ring 4231 is provided with guide holes 4232, and the guide holes 4232 are evenly distributed on the fixing ring 4231 in a circular shape.

[0071] In the embodiment of the present application, by setting a fixing ring 4231, an overflow area of ​​a certain size can be present between the support ring 423 and the guide space, so that excess glue can solidify in this area, thereby achieving bonding and fixation 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 improving the stability of the support assembly 4, thereby achieving an improvement in the overall flatness of the support plate 2, and further improving the flatness of the substrate layer 31 and dispersing the actual force during the heating process.

[0072] In some optional embodiments, the fixing nut 41 includes a fixing thread ring 411 and a nut shell 412, the fixing thread ring 411 is arranged on the top surface of the nut shell 412, the fixing thread ring 411 is threadedly connected to the bottom surface of the plate, and the nut shell 412 is threadedly connected to the screw body 421.

[0073] In the embodiment of the present application, the nut housing 412 is fixed to the bottom surface of the supporting plate 2 by fixing the threaded ring 411, and the hollow adjusting screw 42 can be adjusted up and down through the nut housing 412, so that the supporting assembly 4 can further maintain the flatness of the supporting plate 2, thereby improving the flatness of the substrate layer 31 and dispersing the actual force during the heating process.

[0112] In summary, the portable dry floor heating system provided in the embodiment of the present application is compared with the assembled dry floor heating system using the traditional XPS material or EPS material as the substrate layer 31. By replacing it with a polyethylene terephthalate (PET) substrate layer 31 or a polyurethane (PU) substrate layer 31, the substrate layer 31 formed by the PET material or the PU material can make the substrate layer 31 have a high strength of more than 500 kPa and a high melting point of about 250°C. The preparation process can control the thickness of the substrate layer 31 to be less than 25 mm. The substrate layer 31 can be used to effectively reduce the existing The thickness of the substrate layer 31 of XPS material or EPS material can effectively reduce the risk of collapse of the substrate layer 31 caused by overheating of electric heating or water heating. At the same time, the high strength and high melting point characteristics ensure that the substrate layer 31 will not change in thickness and the strength of the supporting plate 2 will not decay due to heat during the normal operation of the heating system; a support assembly 4 including a fixing nut 41, a hollow adjusting screw 42 and an elastic base 43 is used. The distance between the supporting plate 2 and the cement floor 1 can be adjusted by the relative sliding between the hollow adjusting screw 42 and the fixing nut 41, so that the entire heating system is stable, and then the elastic base 43 is used to adjust the distance between the supporting plate 2 and the cement floor 1. The base 43 realizes the flexible contact between the heating system and the cement floor 1, and finally the gap between the elastic base 43 and the small slope cement floor 1 is filled by the adhesive layer 5, and at the same time, the deformation of the elastic base 43 is solidified and formed, and the contact mode between the elastic base 43 and the cement floor 1 is changed from flexible contact to a mixed contact mode of flexible contact and rigid contact, thereby increasing the pressure that the elastic base 43 can withstand, and then improving the overall flatness of the supporting plate 2, so that the substrate layer 31 fixedly connected to the supporting plate 2 can have a better flatness, and is not easy to deform when subjected to a strong external force, and further can avoid the substrate layer The risk of deformation and collapse of the pit 31 is reduced. Therefore, the heating layer 3 including the substrate layer 31 and the composite aluminum foil layer 32 is matched with the supporting assembly 4 including the fixing nut 41, the hollow adjusting screw 42 and the elastic base 43, so as to improve the flatness of the substrate layer 31 and disperse the actual force during the heating process. At the same time, the high strength and high melting point of the substrate layer 31 and the highly stable physical and chemical properties can be used to effectively reduce the strength change of the substrate layer 31 during the heating stage, thereby comprehensively improving the internal and external force states of the substrate layer 31, thereby reducing the overall thickness of the substrate layer 31, thereby increasing the floor height space of the prefabricated dry floor heating system.
