Description

Technical Field

[0001] This utility model belongs to the technical field of underfloor heating materials, specifically a reinforced underfloor heating pipe. Background Technology

[0002] Reinforced underfloor heating pipes are high-performance pipes designed to enhance system performance. They are not made of a single material, but achieve superior performance through an innovative composite structure. The main examples are aluminum-plastic composite pipes and oxygen-barrier plastic pipes. By bonding a layer of metallic aluminum or high-molecular-weight EVOH oxygen-barrier layer between ordinary PE-RT plastic layers, the pipes possess near-perfect oxygen barrier properties, effectively preventing oxygen from penetrating and corroding the system's metal components, thus greatly extending the lifespan of the entire heating system. Simultaneously, this composite structure also endows the pipes with higher pressure resistance, better dimensional stability (virtually no expansion or contraction under heat), and better shape retention, ensuring the safety, stability, and efficiency of the underfloor heating system during long-term use.

[0003] Patent document CN209355336U describes a reinforced polyethylene underfloor heating pipe, including a pipe body with four sets of four-way connectors fixedly connected at one end. The outer side of the pipe body is provided with an insulating rock wool sleeve and a heat-conducting copper pipe. The vertical cross-section of the anti-scaling plastic sheet is triangular, with its two ends respectively located at both ends of the pipe body. A flow-guiding groove is opened at the bottom of the inner cavity of the pipe body. The insulating rock wool sleeve is placed outside the pipe body and is fixedly bonded to the outer wall of the pipe body. The heat-conducting copper pipe is embedded in the top of the insulating rock wool sleeve and contains a heat-conducting liquid. A flow-diverting column is also provided inside the heat-conducting copper pipe. The aforementioned reinforced polyethylene underfloor heating pipes have certain shortcomings in use. Traditional reinforced underfloor heating pipes have a circular cross-section, which requires a certain thickness of flooring during installation, affecting the indoor ceiling height. Furthermore, the circular pipe structure has a smaller heat dissipation surface, reducing the effectiveness of the underfloor heating system. Secondly, underfloor heating pipes are laid in an S-shape, and the bending points can damage the floor material due to excessive rebound force. They are generally fixed with clips, but excessive use of clips can damage the insulation layer, affecting the insulation effect of the underfloor heating pipes. Utility Model Content

[0004] This utility model provides a reinforced underfloor heating pipe that solves the problems of traditional reinforced underfloor heating pipes with circular cross-sections, which require a certain thickness of flooring for installation, affecting the indoor ceiling height. Furthermore, the circular pipe structure has a smaller heat dissipation surface, reducing the effectiveness of the underfloor heating system. Additionally, the S-shaped routing of the pipes during installation can cause damage to the flooring material due to excessive springback at the bends. A reinforced underfloor heating pipe includes an inner lining layer and an aluminum pipe layer. The aluminum pipe layer is fixedly sleeved on the outside of the inner lining layer. An inner hot melt adhesive layer covers the space between the aluminum pipe layer and the inner lining layer. An outer lining layer is fixedly sleeved on the outside of the aluminum pipe layer. An outer hot melt adhesive layer covers the space between the aluminum pipe layer and the outer lining layer. The cross-sections of the outer lining layer, the outer hot melt adhesive layer, the aluminum pipe layer, the inner hot melt adhesive layer, and the inner lining layer are all elliptical. The outer surface of the outer lining layer is fixed by several sets of fasteners. The lower part of each fastener is provided with an insulation pad for use with the outer lining layer. The outer surface of the insulation pad is provided with several sets of mounting grooves.

[0005] As a further technical solution of this utility model, the lower part of the clip is fixedly installed with a first nail leg and a second nail leg. The first nail leg is located on one side of the second nail leg, and the first nail leg and the second nail leg are symmetrically arranged. By using the arrangement of the first nail leg and the second nail leg, the floor heating pipe can be clipped between the insulation pad and the clip, and the fixing operation of the floor heating pipe can be quickly completed.

[0006] As a further technical solution of this utility model, the upper middle part of the clip is provided with an arc-shaped groove, and an arc-shaped pad is installed in the arc-shaped groove of the clip. The overall cross-section of the underfloor heating pipe is an elliptical structure, which makes the upper surface of the underfloor heating pipe flat. Compared with the traditional circular structure, the elliptical structure of the underfloor heating pipe can effectively increase its heat conduction effect, have a larger heat dissipation area for the same length, and can reduce the thickness of the floor and reduce the impact on the indoor ceiling height.

[0007] As a further technical solution of this utility model, the lower outer surfaces of the second and first nail legs are fixedly installed with docking clips. Both sides of the docking clips are inclined structures. The docking clips can be used to dock with the mounting groove at the upper end of the insulation pad, thereby completing the docking and fixing of the first and second nail legs.

[0008] As a further technical solution of this utility model, the outer surfaces of the first and second nail legs are fixedly equipped with limiting pads for use with the docking head. The two sets of limiting pads are symmetrically arranged. Traditional nail structures are shot out by a nail gun, which makes it impossible to accurately control the insertion depth of the nail when docking with the insulation layer. This can easily damage the insulation material and reduce the insulation effect on the geothermal pipe. The setting of the limiting pads can limit the insertion depth of the docking head when docking with the installation groove. Through the contact between the limiting pads and the upper surface of the insulation pad, the docking head is controlled at a fixed depth. At the same time, the flat head structure at the bottom of the docking head can effectively prevent the docking head from penetrating the insulation pad when inserted into the installation groove, thus providing good protection for the insulation pad.

[0009] As a further technical solution of this utility model, the side of the clip is equipped with several sets of combined clips, which are spliced ​​and fixed with the clip. When the underfloor heating pipe is installed, the underfloor heating pipe is installed in an S-shape. The elliptical structure of the underfloor heating pipe may damage the ground material due to excessive rebound force at the bending position. By adding combined clips, the clip has a multi-point fixing installation structure, which improves the fixing strength of the clip and prevents the underfloor heating pipe from springing up.

[0010] As a further technical solution of this utility model, the combined clip has an overall L-shaped structure, and a mating buckle is fixedly installed on the outer surface of one end of the clip. The L-shaped structure design can extend the fixing point of the combined clip outward, and the mating buckle plays a splicing and fixing role in the installation of the combined clip.

[0011] As a further technical solution of this utility model, the outer surface of the clip is provided with a splicing groove for use with mating buckles. Several sets of splicing grooves are symmetrically arranged. Through the symmetrically arranged splicing grooves, several sets of combined clips maintain the same height after installation.

[0012] As a further technical solution of this utility model, the lower outer surface of the combined clamping foot is fixedly installed with a docking clamping head, and the outer surface of the combined clamping foot is provided with a limiting pad at the upper part of the docking clamping head. The combined clamping foot adopts the same fixing structure design as the first nail leg and the second nail leg, thereby improving the uniformity of its installation structure.

[0013] As a further technical solution of this utility model, several sets of mounting grooves are arranged in an array, and the depth of the mounting grooves is half the thickness of the insulation pad.

[0014] The beneficial effects of this utility model are as follows: By setting the cross-section of the underfloor heating pipe to an elliptical structure, the upper surface of the underfloor heating pipe is flattened during installation. Compared with the traditional circular structure, the elliptical structure of the underfloor heating pipe can effectively increase its heat conduction, providing a larger heat dissipation area for the same length. It also reduces the thickness of the flooring, minimizing the impact on the indoor ceiling height and improving the heat dissipation effect of the underfloor heating pipe itself. Furthermore, to facilitate the installation of the elliptical structure underfloor heating pipe, fasteners are used to quickly complete the installation without damaging the insulation layer. Traditional installation of geothermal pipes using clips fired from a nail gun makes it difficult to precisely control the insertion depth of the clips when they align with the insulation layer. This can easily damage the insulation material and reduce the insulation effect of the geothermal pipes. However, the setting of the limiting plate can limit the insertion depth of the connecting clip when it aligns with the installation groove. By contacting the upper surface of the limiting plate and the insulation pad, the connecting clip is controlled at a fixed depth. At the same time, the flat-head design at the bottom of the connecting clip can effectively prevent the connecting clip from penetrating the insulation pad when it is inserted into the installation groove, thus providing good protection for the insulation pad. By incorporating a combination of locking feet, the installation structure of this reinforced underfloor heating pipe is optimized. This design provides multi-point fixation during bending, preventing the pipe from tilting upwards and improving the overall stability of the installation. When the underfloor heating pipes are installed in an S-shape, the elliptical shape can cause excessive rebound force at bends, potentially damaging the floor material. The addition of combination locking feet provides multi-point fixation, increasing the fixing strength and preventing the pipes from bouncing upwards. The L-shaped design extends the fixing points of the locking feet outwards, and the connecting clips further secure the locking feet during installation. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-3As shown, a reinforced underfloor heating pipe includes an inner lining layer 5 and an aluminum pipe layer 3. The aluminum pipe layer 3 is fixedly sleeved on the outside of the inner lining layer 5. An inner hot melt adhesive layer 4 covers the space between the aluminum pipe layer 3 and the inner lining layer 5. An outer lining layer 1 is fixedly sleeved on the outside of the aluminum pipe layer 3. An outer hot melt adhesive layer 2 covers the space between the aluminum pipe layer 3 and the outer lining layer 1. The cross-sections of the outer lining layer 1, the outer hot melt adhesive layer 2, the aluminum pipe layer 3, the inner hot melt adhesive layer 4, and the inner lining layer 5 are all elliptical. The outer surface of the outer lining layer 1 is fixed by several sets of fasteners 6. The lower part of the fasteners 6 is provided with a heat insulation pad 12 for use with the outer lining layer 1. The outer surface of the heat insulation pad 12 is provided with several sets of installation grooves 13. Both the inner lining layer 5 and the outer lining layer 1 are PE-RT base layers, i.e., heat-resistant reinforced polyethylene material.

[0020] The lower part of the clip 6 is fixedly installed with a first nail leg 8 and a second nail leg 9. The first nail leg 8 is located on one side of the second nail leg 9. The first nail leg 8 and the second nail leg 9 are symmetrically arranged. By using the arrangement of the first nail leg 8 and the second nail leg 9, the underfloor heating pipe can be clipped between the insulation pad 12 and the clip 6, and the fixing operation of the underfloor heating pipe can be quickly completed.

[0021] The upper center of the clip 6 has an arc-shaped groove, and an arc-shaped pad 7 is installed in the arc-shaped groove of the clip 6. The overall cross-section of the underfloor heating pipe is an elliptical structure, which makes the upper surface of the underfloor heating pipe flat. Compared with the traditional circular structure, the elliptical structure of the underfloor heating pipe can effectively increase its heat conduction effect, have a larger heat dissipation area for the same length, and can reduce the thickness of the floor and reduce the impact on the indoor ceiling height.

[0022] The lower outer surfaces of the second nail leg 9 and the first nail leg 8 are both fixedly equipped with docking heads 11. Both sides of the docking heads 11 are beveled structures. The docking heads 11 can be used to dock with the mounting groove 13 at the upper end of the insulation pad 12, thereby completing the docking and fixing of the first nail leg 8 and the second nail leg 9.

[0023] The outer surfaces of the first nail leg 8 and the second nail leg 9 are both fixedly equipped with limiting pads 10 for use with the docking head 11. The two sets of limiting pads 10 are symmetrically arranged. Traditional nail structures use nail guns to shoot out the nails, which makes it impossible to accurately control the insertion depth of the nails when they dock with the insulation layer. This can easily damage the insulation material and reduce the insulation effect on the geothermal pipe. However, the setting of the limiting pads 10 can limit the insertion depth of the docking head 11 when it docks with the installation groove 13. Through the contact between the limiting pads 10 and the upper surface of the insulation pad 12, the docking head 11 is controlled at a fixed depth. At the same time, the flat-head structure at the bottom of the docking head 11 can effectively prevent the docking head 11 from penetrating the insulation pad 12 when it is inserted into the installation groove 13, thus providing good protection for the insulation pad 12.

[0024] The side of the clip 6 is equipped with several sets of combined clips 14. The combined clips 14 and the clip 6 are spliced ​​and fixed together. When the underfloor heating pipe is installed, the underfloor heating pipe is installed in an S-shape. The elliptical structure of the underfloor heating pipe may damage the floor material due to excessive rebound force at the bending position. By adding combined clips 14, the clip 6 has a multi-point fixing installation structure, which improves the fixing strength of the clip 6 and prevents the underfloor heating pipe from springing up.

[0025] The overall structure of the combination clip 14 is L-shaped. A mating buckle 16 is fixedly installed on the outer surface of one end of the clip 6. The L-shaped structure design can extend the fixing point of the combination clip 14 outward. The mating buckle 16 plays a role in splicing and fixing the installation of the combination clip 14.

[0026] The outer surface of the clip 6 is provided with splicing grooves 15 for use with mating buckles 16. Several sets of splicing grooves 15 are symmetrically arranged. Through the symmetrically arranged splicing grooves 15, several sets of combined clips 14 maintain the same height after installation.

[0027] The lower outer surface of the combination clamp 14 is fixedly equipped with a docking head 11. The outer surface of the combination clamp 14 is provided with a limiting pad 10 above the docking head 11. The combination clamp 14 adopts the same fixing structure design as the first nail leg 8 and the second nail leg 9, which improves the uniformity of its installation structure.

[0028] Several sets of mounting slots 13 are arranged in an array, and the depth of the mounting slots 13 is half the thickness of the insulation pad 12.

[0029] A reinforced underfloor heating pipe, when used, features an elliptical cross-section. This design allows for a flattened upper surface during installation, significantly increasing heat conduction compared to a traditional circular structure. It provides a larger heat dissipation area for the same length, reduces floor thickness, minimizes impact on ceiling height, and enhances overall heat dissipation. Furthermore, to facilitate installation, a locking clip (6) allows for quick installation without damaging the insulation layer. Traditional clips... The structure uses a nail gun for injection, which makes it difficult to precisely control the insertion depth of the nails when they are inserted into the insulation layer. This can easily damage the insulation material and reduce the insulation effect on the geothermal pipes. However, the setting of the limiting pad 10 can limit the insertion depth of the docking head 11 when it is connected to the mounting groove 13. By the contact between the limiting pad 10 and the upper surface of the insulation pad 12, the docking head 11 is controlled at a fixed depth. At the same time, the flat head structure at the bottom of the docking head 11 can effectively prevent the docking head 11 from penetrating the insulation pad 12 when it is inserted into the mounting groove 13, thus providing good protection for the insulation pad 12. By setting the combined clamp 14, the use of the mounting clip 6 is optimized when using this reinforced underfloor heating pipe. During the fixing operation at the bending position, it provides a multi-point fixing structure, preventing the pipe from tilting upwards at the bend and improving the overall stability of the underfloor heating pipe installation. When the underfloor heating pipe is installed in an S-shape, the elliptical structure of the pipe can damage the floor material due to excessive rebound force at the bend. By adding the combined clamp 14, the clip 6 has a multi-point fixing installation structure, increasing the fixing strength of the clip 6 and preventing the underfloor heating pipe from bouncing upwards. The L-shaped design extends the fixing points of the combined clamp 14 outwards, and the connecting clip 16 provides a splicing and fixing function for the installation of the combined clamp 14.

[0030] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
