Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric floor heating technology, and in particular to a prefabricated floor radiant base plate connection structure. Background Technology
[0002] In modern architecture, radiant floor heating systems are widely used due to their high efficiency, energy saving, and comfort. The radiant floor slab, as a key component of the system, directly affects the overall heating effect and stability through its performance and installation method. Traditionally, radiant floor slab installation on the floor leveling layer involves either directly placing multiple slabs on the leveling layer or using adhesive to splice them together. However, these methods have revealed numerous problems in practical applications. During splicing, each slab requires individual positioning and leveling adjustments, which is labor-intensive and time-consuming. Furthermore, because the slab independently bears the floor load, the load-bearing capacity of the radiant floor slab material is relatively high. Generally, a concrete overlay layer needs to be poured on-site, increasing material costs. When the radiant floor slab is damaged or needs replacement, traditional installation methods make repair and replacement very difficult. Once a malfunction or damage occurs, it often requires disturbing a large area of the floor for repair. Utility Model Content
[0003] In view of the problems existing in the prior art, the present invention aims to provide a prefabricated ground radiation base plate connection structure to solve the problems of high construction complexity, poor connection stability, and difficulty in maintenance and replacement of traditional ground radiation base plate installation structures.
[0004] To achieve the above objectives, this utility model proposes a prefabricated ground radiation base plate connection structure for splicing multiple base plates. It includes a support connector comprising a connecting bracket panel and a connecting bracket base. Each base plate has a recessed platform at each end of its top and bottom surfaces, and each recessed platform has a through hole. Adjacent bottom recessed platforms of adjacent base plates are combined to form an overall bottom recessed platform, and adjacent top recessed platforms of adjacent base plates are combined to form an overall top recessed platform. The connecting bracket base is fitted into the overall bottom recessed platform, and the connecting bracket panel is fitted into the overall top recessed platform. Each through hole on the connecting bracket base corresponds to a support rod, which passes through the through hole and is detachably connected to the connecting bracket panel, thereby achieving the connection of adjacent base plates.
[0005] In the above solution: the base plate is a rectangular base plate, with recessed platforms at all four ends of the top and bottom surfaces. Four adjacent rectangular base plates are joined and fixed together using a single support connector. This single support connector allows for the simultaneous joining and fixing of all four rectangular base plates. Compared to the traditional piece-by-piece joining method, this reduces the number of connectors and installation steps, significantly shortening installation time, improving construction efficiency, and lowering labor costs.
[0006] In the above scheme: the bottom and top recessed platforms are circular or rectangular, the connecting bracket base is circular or rectangular and fits the bottom recessed platform, and the connecting bracket panel is circular or rectangular and fits the top recessed platform. That is, the recessed platform at the end of the bottom plate can be arranged in the form of a small rectangle or a quarter circle, which is convenient for installation.
[0007] In the above solution: the support member is a column structure, the through hole is a cylindrical through hole matching the column structure, the column structure has an insertion hole, and the bottom surface of the connecting bracket panel has column-shaped plugs corresponding to each column structure. Each column-shaped plug is inserted into the corresponding insertion hole to achieve the connection between the connecting bracket panel and the connecting bracket base, thereby achieving the connection between adjacent base plates. The plug-in connection method effectively ensures the stable connection of adjacent base plates in all directions, enabling the entire underfloor heating composite module system to withstand various complex external forces, improving the system's reliability and service life.
[0008] In the above solution: the support member is a sleeve, the through hole is a cylindrical through hole matching the sleeve, the sleeve has a threaded hole, and the connecting bracket panel has screw mounting holes corresponding to each sleeve. Each screw mounting hole is equipped with a screw, and each screw passes through the screw mounting hole and is fixed in the corresponding threaded hole to realize the connection between the connecting bracket panel and the connecting bracket base, thereby realizing the connection between adjacent base plates. The threaded connection effectively ensures the stable connection of adjacent base plates in all directions, enabling the entire underfloor heating composite module system to withstand various complex external forces, improving the reliability and service life of the system.
[0009] In the above solution: an anti-disengagement structure is provided between the socket and the cylindrical plug. The anti-disengagement structure includes a ring of protrusions on the cylindrical plug and a ring of grooves inside the socket. The protrusions and grooves match, which further improves the connection stability between the connecting bracket panel and the connecting bracket base.
[0010] In the above solution: the screw mounting hole is a tapered hole, and the screw head is precisely embedded and locked in the tapered hole, so that the surface after installation is flat and smooth, without the problem of the screw head protruding.
[0011] The above solution also includes a T-shaped bracket, which is installed in the gap between two adjacent base plates. A single T-shaped bracket extends between two adjacent support connectors. The connecting bracket panel has a slot that matches the end of the horizontal section of the T-shaped bracket, and the slot has a through hole for the vertical section of the T-shaped bracket to pass through. The top surface of the connecting bracket base has a recessed groove for the bottom end of the T-shaped bracket to be embedded. The top surface of the base plate has recessed platforms around its four edges. The vertical section of the T-shaped bracket passes through the corresponding gap and through hole and is embedded in the corresponding recessed groove. The horizontal section of the T-shaped bracket is fitted into two adjacent recessed platforms and corresponding slots. The top surface of the T-shaped bracket is flush with the top surface of the base plate, and the T-shaped bracket can also play a load-bearing role.
[0012] The beneficial effects of this utility model are:
[0013] 1. An integrated recessed platform is formed by combining the top and bottom surfaces of adjacent base plates. Supporting connectors fitted within this integrated platform tightly connect the adjacent base plates, creating a stable overall structure. This effectively improves the overall stability and load-bearing capacity of the underfloor heating system, reducing the risk of structural damage due to base plate loosening or displacement. 2. The connecting bracket base is fitted to the bottom integrated recessed platform, and the connecting bracket panel is fitted to the top integrated recessed platform. Support members pass through through holes and are detachably connected to the connecting bracket panel. This multi-layered connection method ensures the robustness of the connection between adjacent base plates, enabling it to withstand significant external forces, such as pressure from foot traffic and furniture placement. It prevents base plate separation or loosening, allowing the supporting connectors to serve as the primary load-bearing components of the underfloor heating system. 3. The connection structure is rationally designed and relatively simple to operate. When splicing multiple base plates, simply place the connecting bracket base of the support connector into the bottom recessed platform, place the connecting bracket panel into the top recessed platform, and then detachably connect the support rods to the connecting bracket panel to complete the installation. This greatly shortens the installation time, improves construction efficiency, and reduces labor costs. 4. Due to the detachable connection method, when a base plate is damaged or needs replacement, only the corresponding support rods and connecting bracket panel need to be removed to remove and replace the damaged base plate. There is no need for large-scale dismantling of the entire ground radiation base plate system, resulting in low maintenance costs and minimal impact on normal use. Attached Figure Description

[0028] Example 1
[0029] like Figure 1 As shown in Figure 8, a reversible prefabricated electric radiant heating floor mainly consists of multiple base plates and panels.
[0030] The base plate is laid on the leveling layer. The base plate includes a thermal insulation and sound insulation layer. The thermal insulation and sound insulation layer is an integral structure or is composed of a base plate sound insulation layer 3 and a base plate thermal insulation core material layer 4 covering the base plate sound insulation layer 3. The base plate thermal insulation core material layer 4 is covered with a protective layer 7. The protective layer 7 is the outer layer of the base plate thermal insulation core material layer 4, which plays the role of fire prevention and increasing strength.
[0031] The panel includes a panel base layer 1 and a panel finishing layer 2 covering the panel base layer 1. The panel base layer 1 is covered with holes 11, which are through holes or blind holes, arranged in a matrix, or other arrangements. The panel base layer 1 and the panel finishing layer 2 are firmly bonded together with an adhesive. The arrangement of the holes 11 helps to increase the contact area and improve the bonding strength. Moreover, the arrangement of the holes 11 can also improve the heat transfer efficiency to a certain extent.
[0032] Multiple base plates are spliced together in an array by supporting connectors 8 to form a continuous ground cover. Electric heating tapes 5 are laid on the top surface of the base plates. The electric heating tapes 5 are laid flat on the base plates in strips with even intervals. Each panel can be detached and fixed to each base plate. The panels correspond one-to-one with the base plates or one panel corresponds to two or more base plates.
[0033] The heating heating cable 5 is a graphene heating cable. A single graphene heating cable covers multiple base plates, meaning that a single graphene heating cable can be laid continuously. Compared with the traditional laying method, this greatly reduces the number of wire harness joints of the graphene heating element, reduces the risk of possible circuit failures, and improves the stability and reliability of the underfloor heating system.
[0034] The panel is fixed to the base plate by adhesive tape 6. The adhesive tape 6 and the graphene heating tape are staggered to avoid mutual interference between their functions.
[0035] Specifically, the panel finishing layer 2 can be made of materials such as ceramic board or solid wood board, the panel base layer 1 can be made of materials such as calcium silicate board or wood-plastic composite board, and the bottom plate insulation core layer 4 can be made of materials such as polystyrene board or lightweight aggregate composite board. The adhesive tape 6 consists of two parts: one part is placed on the top surface of the bottom plate, and the corresponding part is placed on the bottom surface of the panel. When the bottom plate and panel are joined, the two parts are bonded together. Specifically, it can be Velcro or other adhesive tape 6 that meets the requirements, facilitating reverse opening. Velcro has a long service life, typically capable of over 30,000 openings and closings, fully meeting the service life requirements of reversible prefabricated electric radiant heating floor systems. Furthermore, once bonded, the panel will not slide horizontally, meeting usage requirements.
[0036] Furthermore, the use of interlocking connectors 8 with the base plate allows for full-area installation throughout the room. This installation structure creates a tight, interlocking connection between the base plates, improving the overall stability and load-bearing capacity during installation, meeting the required load conditions, and ensuring the long-term stable and efficient operation of the underfloor heating system.
[0037] The base plate is rectangular, and the four adjacent base plates are spliced together by support connectors 8. The support connectors 8 include detachable connecting bracket panels 81 and connecting bracket bases 82. The connecting bracket panels 81 and connecting bracket bases 82 are circular or rectangular. The rectangular base facilitates positioning and arrangement during splicing, and the detachable support connectors 8 make the splicing process simpler and more intuitive.
[0038] The supporting connector 8 has two structural forms. One form has recessed platforms 12 at all four ends of the top and bottom surfaces of the base plate. Each recessed platform 12 has a cylindrical through hole for splicing the supporting connector 8. The recessed platforms 12 on adjacent top surfaces of adjacent base plates are combined to form a circular or rectangular recessed platform that fits into the connecting bracket panel 81. The recessed platforms 12 on adjacent bottom surfaces are combined to form a circular or rectangular recessed platform that fits into the connecting bracket base 82. The connecting bracket base 82 is fitted onto the circular recessed platform on the bottom surface of the base plate. In the recessed platform or rectangular platform, a column structure 85 with cylindrical through holes passing through each base plate is provided on its top surface. The column structure 85 has insertion holes. A connecting bracket panel 81 is fitted into the circular or rectangular recessed platform on the top surface of the base plate. A column-shaped plug 86 is provided on the bottom surface of the connecting bracket panel 81 corresponding to each column structure 85. Each column-shaped plug 86 is inserted into its corresponding insertion hole to connect the connecting bracket panel 81 to the connecting bracket base 82, thereby connecting adjacent base plates. This plug-in connection method effectively ensures stable connection between adjacent base plates in all directions, enabling the entire underfloor heating composite module system to withstand various complex external forces, improving the system's reliability and service life.
[0039] An anti-disengagement structure is provided between the socket and the post plug 86. The anti-disengagement structure includes a ring of protrusions on the post plug 86 and a ring of grooves inside the socket. The protrusions and grooves match, which further improves the connection stability between the connecting bracket panel 81 and the connecting bracket base 82.
[0040] Another configuration involves recessed platforms 12 at all four ends of the top and bottom surfaces of the base plate. Each recessed platform 12 has a cylindrical through-hole for supporting the splicing of the connector 8. Adjacent recessed platforms 12 on the top surfaces of adjacent base plates combine to form circular or rectangular recessed platforms that fit with the connecting bracket panel 81. Adjacent recessed platforms 12 on the bottom surfaces combine to form circular or rectangular recessed platforms that fit with the connecting bracket base 82. The connecting bracket base 82 is fitted into the circular or rectangular recessed platforms on the bottom surface of the base plate. A through-hole is also provided on its top surface. A sleeve 87, with a threaded hole inside each of the cylindrical through holes in the base plates, is fitted onto a circular or rectangular recess on the top surface of the base plate. The connecting bracket panel 81 is provided with screw mounting holes 83 corresponding to each sleeve 87. Each screw mounting hole 83 is equipped with a screw 84, which passes through the screw mounting hole 83 and is fixed in the corresponding threaded hole, thus connecting the connecting bracket panel 81 to the connecting bracket base 82, and consequently connecting adjacent base plates. This threaded connection effectively ensures a stable connection between adjacent base plates in all directions, enabling the entire underfloor heating composite module system to withstand various complex external forces, improving the system's reliability and service life.
[0041] The screw mounting hole 83 is a tapered hole, and the head of the screw 84 is precisely embedded and locked in the tapered hole, making the surface flat and smooth after installation, without the problem of the screw head protruding.
[0042] The electric radiant heating floor is mainly supported by the four corner support connectors 8 of each base plate.
[0043] The bottom surface of the connecting bracket base 82 is covered with a bottom plate sound insulation layer 3. The bottom plate sound insulation layer 3 has the same thickness as the bottom plate sound insulation layer 3 below the bottom plate heat insulation core material layer 4, which is equivalent to building a continuous and uniform sound insulation barrier in the entire electric radiant heating floor.
[0044] The adhesive tape 6 is laid between the top surface lines of each support connector 8 in the same row or column, and its width is the same as the width of the support connector 8. The graphene heating tape 5 is laid between two adjacent adhesive tapes 6. This structure is ingeniously designed, providing a clear positioning reference for the laying of the graphene heating tape 5, while avoiding mutual interference between the two.
[0045] Example 2
[0046] In addition to the structure of Embodiment 1, it also includes a T-shaped bracket 13, which is arranged in the gap between two adjacent base plates, and a single T-shaped bracket 13 extends between two adjacent support connectors 8.
[0047] like Figure 9 As shown in Figure 14, when the T-shaped bracket 13 is included, the connecting bracket panel 81 is provided with a slot 801 that matches the end of the horizontal section of the T-shaped bracket 13, and the slot 801 is provided with a through hole for the vertical section of the T-shaped bracket 13 to pass through. The top surface of the connecting bracket base 82 is provided with a recessed groove 802 for the bottom end of the T-shaped bracket 13 to be embedded. The four edges of the top surface of the base plate are provided with recessed platforms 14. The vertical section of the T-shaped bracket 13 passes through the corresponding gap and through hole and is embedded in the corresponding recessed groove 802. The horizontal section of the T-shaped bracket 13 is fitted into two adjacent recessed platforms 14 and corresponding slots 801 (equivalent to four T-shaped brackets 13 in the front-back, left-right directions being connected on a support connector 8, four slots 801 being opened on the connecting bracket panel 81, and four recessed grooves 802 being opened on the connecting bracket base 82). The top surface of the T-shaped bracket 13 is flush with the top surface of the base plate, and the T-shaped bracket 13 can also play a role in bearing load.
