Description
Technical Field
[0001] This utility model belongs to the field of pipeline installation technology, specifically relating to an installation structure for underfloor heating pipelines. Background Technology
[0002] Underfloor heating is a heating method that uses radiant heat from the floor. Due to its comfort, energy efficiency, and space-saving advantages, it has become a common heating choice for modern homes. Types and principles of underfloor heating: Water-based underfloor heating: A boiler heats circulating water, which then circulates through pipes under the floor, radiating and convection into the room. Features: Suitable for large areas and long-term use (such as villas and large apartments); requires a wall-mounted boiler or centralized heating; heats up slowly but retains heat well. Electric underfloor heating: Heats up through heating cables or carbon fiber membranes, directly converting electrical energy into heat. Suitable for small areas and intermittent use (such as bathrooms and small apartments); heats up quickly but consumes more energy. The underfloor heating pipes are the core component of the system. Their material, installation, and maintenance directly affect the system's safety, lifespan, and heating effect. Underfloor heating pipe materials include PERT, PEX, PB, and aluminum-plastic composite pipes.
[0003] Traditional underfloor heating pipe fixing devices mostly use integral rigid clamps, directly locking the pipe surface with bolts. This type of structure, lacking a longitudinal displacement compensation mechanism, easily creates rigid stress concentration between the pipe and the fixing components when the pipe expands due to heat, leading to pipe deformation or leakage at connections over time. Furthermore, the opening size of the fixing clamp is usually matched to a specific pipe diameter; when the pipe diameter changes during a project, the entire clamp assembly needs to be replaced, increasing construction complexity and creating material inventory pressure. In addition, traditional rigid clamping methods require high installation precision; positional deviations affect the clamping effect, making it difficult to meet the comprehensive requirements of modern underfloor heating systems for installation efficiency and compatibility. Therefore, a new underfloor heating pipe installation structure is proposed. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides an installation structure for underfloor heating pipes, which solves the technical problem that the opening size of the aforementioned fixing clamps is usually matched with a specific pipe diameter, and when the pipe diameter changes during the project, the entire clamp assembly needs to be replaced, increasing the complexity of construction.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor heating pipe installation structure, comprising: The mounting base and the column set on the upper surface of the mounting base, and the outer side of the column is provided with side connecting plates all around, and a clamping assembly is slidably connected to the center of the front of the side connecting plate, and the clamping assembly consists of an upper clamping plate and a lower clamping plate. The guide rod is set on both sides of the inner cavity of the side connecting plate, and the upper and lower clamping plates are slidably connected to the surface of the guide rod. A return spring is sleeved on both the upper and lower parts of the surface of the guide rod. A connecting column is positioned at the center of the outer perimeter of the upright column, with its outer end connected to the center of the back of the corresponding side connecting plate. The inner end of the connecting column extends inward through the outer wall of the upright column, and a compression spring is installed between the inner end of the connecting column and the inner wall of the upright column. The mounting base is fixed to the ground or base surface through pre-set fixing holes to form a basic support structure. Push the side connecting plates around the outside of the column to make the connecting column slide along the inner wall of the column and compress the squeeze spring, so as to adjust the distance between the side connecting plates and the column to adapt to the layout requirements of pipes of different sizes. Pull the upper clamping plate upward along the guide rod or press the lower clamping plate downward to compress the return spring and expand the gap between the upper and lower clamping plates; Place the underfloor heating pipes horizontally on the surface of the lower clamping plate, and slowly release the upper or lower clamping plate. The return spring drives the clamping assembly to close through the elastic restoring force, so that the inner arc surface of the upper and lower clamping plates fits against the outer wall of the pipe. Multiple pipes are clamped and installed sequentially on the side connecting plates around the column to form a grid-like pipe layout.
[0006] Furthermore, the upper surface of the mounting base is respectively provided with a limiting vertical groove and a limiting horizontal groove, and the limiting horizontal groove is connected to the limiting vertical groove. Inlet and outlet circular holes are provided at the ends of both the limiting vertical groove and the limiting horizontal groove. As a basic support structure, the upper surface of the mounting base forms a cross guide rail system through the limiting vertical groove and the limiting horizontal groove. The connection design between the limiting horizontal groove and the limiting vertical groove allows the component to switch its movement path in both vertical and horizontal directions. When it is necessary to insert or remove a functional component, the axial insertion and removal operation of the component can be achieved through the inlet and outlet circular holes at the ends of the limiting vertical groove and the limiting horizontal groove.
[0007] Furthermore, the inner cavities of both the limiting vertical groove and the limiting horizontal groove are slidably connected to limiting base plates, and the limiting base plates are connected to the bottom of the side connecting plate. The limiting base plates slide directionally along the inner cavities of the limiting vertical groove and the limiting horizontal groove, and their movement trajectory is limited by the contour of the grooves. When the limiting base plates move to a predetermined position, the vertical or horizontal displacement is transmitted to the side connecting plate through the rigid connection structure with the bottom of the side connecting plate, thereby realizing the spatial position adjustment of the side connecting plate.
[0008] Furthermore, both sides of the front of the side connecting plate are provided with sliding grooves, and the guide rod and the return spring are both disposed within the sliding grooves. The sliding grooves on both sides of the front of the side connecting plate provide vertical guide channels for functional components. The guide rod, as the core guide element within the sliding groove, has its axis aligned with the length direction of the sliding groove. The return spring is disposed at the end of the sliding groove and absorbs motion impact and provides restoring force through elastic deformation and built-in rubber pads.
[0009] Furthermore, guide blocks are fitted at the upper and lower parts of the center position of the guide rod surface, and the guide blocks are tightly fitted with the corresponding ends of the return springs. The upper and lower clamping plates are connected to the corresponding guide blocks through sliding grooves. The guide blocks fitted at the upper and lower parts of the center position of the guide rod surface move linearly along the axis of the guide rod. The tight fit between the guide blocks and the ends of the return springs ensures that the spring force acts directly on the guide blocks. The upper and lower clamping plates are connected to the guide blocks through sliding grooves, and the opening and closing action is realized as the guide blocks move.
[0010] Furthermore, a hollow chamber is formed at the center of the inner cavity of the column, and a fixed column is installed at the center of the hollow chamber, with the compression spring connected to the fixed column. The hollow chamber of the column provides space for the functional components, and the fixed column is vertically installed at the center of the hollow chamber, with its outer cylindrical surface engaging with the inner ring of the compression spring. When an external load is applied to the column, the compression spring absorbs energy through axial compression deformation and the built-in rubber, while the fixed column serves as the spring mounting reference to maintain structural stability. Beneficial effects
[0011] This underfloor heating pipe installation structure employs a split upper and lower clamping plate structure with a double guide rod design at the longitudinal clamping level. This allows the clamping components to move vertically along the guide rods. The bidirectional preload of the return spring ensures stable clamping of the pipe and creates a dynamic buffer space. When the pipe undergoes axial deformation due to thermal expansion and contraction, the upper and lower clamping plates can slide synchronously with the pipe displacement, avoiding stress concentration in the pipe body caused by rigid constraints. This design, through the matching and adjustment of the spring force and the clamping plate spacing, can accommodate underfloor heating pipes of different diameters within a certain range, significantly improving the versatility of the installation structure.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] This utility model provides a technical solution, a floor heating pipe installation structure, including: (See details) Figure 1 , Figure 4 , Figure 5 and Figure 6 Mounting base 1, and a column 5 set on the upper surface of mounting base 1, with side connecting plates 7 added to all four sides of the outer side of column 5, and a clamping assembly 8 slidably connected to the center of the front of the side connecting plate 7, and the clamping assembly 8 is composed of an upper clamping plate 9 and a lower clamping plate 10. The guide rod 12 is located on both sides of the inner cavity of the side connecting plate 7, and the upper clamping plate 9 and the lower clamping plate 10 are slidably connected to the surface of the guide rod 12. A return spring 14 is sleeved on the upper and lower parts of the surface of the guide rod 12. A connecting column 17 is located at the center of the outer perimeter of the column 5, and its outer end is connected to the center of the back of the corresponding side connecting plate 7. The inner end of the connecting column 17 extends inward through the outer wall of the column 5, and a compression spring 18 is provided between the inner end of the connecting column 17 and the inner wall of the column 5. The mounting base 1 is fixed to the ground or base surface through the preset fixing holes to form a basic support structure. Push the side connecting plates 7 around the outer perimeter of the column 5 to make the connecting column 17 slide along the inner wall of the column 5 and compress the spring 18, thereby adjusting the distance between the side connecting plates 7 and the column 5 to accommodate the needs of pipe layout of different sizes. Pull the upper clamping plate 9 upward along the guide rod 12 or press the lower clamping plate 10 downward to compress the return spring 14 and expand the gap between the upper clamping plate 9 and the lower clamping plate 10. Place the underfloor heating pipes horizontally on the surface of the lower clamping plate 10, and slowly release the upper clamping plate 9 or the lower clamping plate 10. The return spring 14 drives the clamping assembly 8 to close through the elastic restoring force, so that the inner arc surface of the upper clamping plate 9 and the lower clamping plate 10 fits against the outer wall of the pipe. Multiple pipes are clamped and installed sequentially on the side connecting plates 7 around the column 5 to form a grid-like pipe layout. The upper clamping plate 9 and the lower clamping plate 10 achieve vertical guiding movement through the guide rod 12. Combined with the bidirectional force application characteristics of the return spring 14, it ensures uniform force during pipe clamping and prevents pipe deformation caused by unilateral force. The double guide rods 12 are symmetrically arranged in the inner cavity of the side connecting plate 7, which effectively restricts the lateral displacement of the clamping assembly 8, ensures that the pipeline axis is perpendicular to the reference plane of the mounting base 1, and improves the installation accuracy. A single mounting base 1 can be configured with multiple sets of side connecting plates 7 and clamping components 8, which can be quickly added or removed through standardized interfaces to meet the heating needs of different areas and reduce construction costs.
[0016] Please see Figure 2 and Figure 3 The upper surface of the mounting base 1 is provided with a limiting vertical groove 2 and a limiting horizontal groove 3, which are connected to the limiting vertical groove 2. Both the limiting vertical groove 2 and the limiting horizontal groove 3 have inlet / outlet holes 4 at their ends. As a basic support structure, the mounting base 1's upper surface forms a cross-guide rail system through the limiting vertical groove 2 and the limiting horizontal groove 3. The connection between the limiting horizontal groove 3 and the limiting vertical groove 2 allows components to switch movement paths in both vertical and horizontal directions. When it is necessary to insert or remove functional components, the axial insertion and removal operations of the components can be achieved through the inlet / outlet holes 4 at the ends of the limiting vertical groove 2 and the limiting horizontal groove 3. The bidirectional guide rail structure formed by the mutually perpendicular limiting vertical groove 2 and the limiting horizontal groove 3, combined with the design of the end inlet / outlet holes 4, ensures accurate positioning of components in the plane and allows for quick assembly and disassembly through the open hole structure, improving the convenience of equipment maintenance. The inner cavities of both the limiting vertical groove 2 and the limiting horizontal groove 3 are slidably connected to the limiting base plate 6, and the limiting base plate 6 is connected to the bottom of the side connecting plate 7. The limiting base plate 6 slides directionally along the inner cavities of the limiting vertical groove 2 and the limiting horizontal groove 3, and its movement trajectory is limited by the contour of the groove. When the limiting base plate 6 moves to the predetermined position, the vertical or horizontal displacement is transmitted to the side connecting plate 7 through the rigid connection structure with the bottom of the side connecting plate 7, thereby realizing the spatial position adjustment of the side connecting plate 7. The sliding cooperation between the limiting base plate 6 and the groove ensures the accuracy of the movement trajectory, and the rigid connection transmits the displacement to the side connecting plate 7, allowing the side connecting plate 7 to flexibly adjust its position according to the working conditions, while maintaining the stability of the overall structure.
[0017] Please see Figure 6The side connecting plate 7 has grooves 11 on both sides of its front surface, and the guide rod 12 and the return spring 14 are both located within the grooves 11. The grooves 11 on both sides of the front surface of the side connecting plate 7 provide vertical guide channels for functional components. The guide rod 12, as the core guide element within the groove 11, has its axis aligned with the length direction of the groove 11. The return spring 14 is located at the end of the groove 11, absorbing motion impact and providing restoring force through elastic deformation and built-in rubber pads. The cooperation between the groove 11 and the guide rod 12 enables linear motion guidance of the functional components. The elastic characteristics of the return spring 14 enable the moving components to have an automatic reset function, while also buffering mechanical impact during operation and extending the service life of the equipment. Guide blocks 13 are fitted at the upper and lower parts of the center position of the guide rod 12, and the guide blocks 13 are tightly fitted with the corresponding ends of the return spring 14. The upper clamping plate 9 and the lower clamping plate 10 are connected to the corresponding guide blocks 13 through the grooves 11. The guide blocks 13, which are sleeved on the upper and lower parts of the center position of the guide rod 12, move linearly along the axis of the guide rod 12. The tight fit between the guide blocks 13 and the end of the return spring 14 ensures that the spring force acts directly on the guide blocks 13. The upper clamping plate 9 and the lower clamping plate 10 are connected to the guide blocks 13 through the slide groove 11, and open and close as the guide blocks 13 move. The cooperation between the guide blocks 13 and the guide rod 12 ensures the straightness of the clamping plate movement. The return spring 14 achieves precise control of the clamping force through the guide blocks 13, so that the upper clamping plate 9 and the lower clamping plate 10 can adapt to the stable clamping of workpieces of different thicknesses.
[0018] Please see Figure 5 A hollow chamber 15 is formed at the center of the inner cavity of the column 5, and a fixed column 16 is installed at the center of the hollow chamber 15, with the compression spring 18 connected to the fixed column 16. The hollow chamber 15 of the inner cavity of the column 5 provides space for functional components. The fixed column 16 is vertically installed at the center of the hollow chamber 15, and its outer cylindrical surface mates with the inner ring of the compression spring 18. When an external load is applied to the column 5, the compression spring 18 absorbs energy through axial compression deformation and the built-in rubber, while the fixed column 16 serves as the spring mounting reference to maintain structural stability. The support system formed by the hollow chamber 15 and the fixed column 16 provides a stable working environment for the compression spring 18, and the load is buffered through the elastic deformation of the spring, effectively reducing the impact of mechanical vibration on the equipment accuracy, while ensuring the vertical load-bearing capacity of the column 5.
[0019] This solution: The mounting base 1 is fixed to the ground or base surface through the preset fixing holes to form a basic support structure. At this time, the limiting vertical groove 2 and the limiting horizontal groove 3 form a cross guide rail system. The limiting base plate 6 slides along the inner cavity of the limiting vertical groove 2 or the limiting horizontal groove 3 to the predetermined position, and drives the side connecting plate 7 to complete the horizontal or vertical position adjustment through rigid connection. When the side connecting plates 7 around the outer perimeter of the column 5 are pushed, the connecting column 17 slides along the hollow cavity 15 on the inner wall of the column 5 and compresses the compression spring 18. The fixed column 16 provides axial support for the compression spring 18, thereby realizing the adjustment of the distance between the side connecting plate 7 and the column 5. Pull the upper clamping plate 9 upward or press the lower clamping plate 10 downward along the sliding grooves 11 on both sides of the front of the side connecting plate 7 to make the guide block 13 slide along the surface of the guide rod 12 and compress the reset spring 14, thereby widening the gap between the upper clamping plate 9 and the lower clamping plate 10. After the underfloor heating pipe is placed horizontally on the surface of the lower clamping plate 10, the clamping assembly 8 is slowly released. The return spring 14 drives the guide block 13 to return to its original position through the elastic restoring force, so that the inner arc surface of the upper clamping plate 9 and the lower clamping plate 10 fits against the outer wall of the pipe. When multiple pipes are clamped and installed sequentially on the side connecting plates 7 around the column 5, the double guide rods 12 are symmetrically arranged in the inner cavity of the slide groove 11. The linear movement of the guide block 13 restricts the lateral displacement of the clamping assembly 8, ensuring that the pipe axis is perpendicular to the reference plane of the mounting base 1. When it is necessary to add or remove the side connecting plate 7 and the clamping assembly 8, the axial insertion and removal operation of the limiting base plate 6 is realized through the inlet and outlet round holes 4 opened at the ends of the limiting vertical groove 2 and the limiting horizontal groove 3, so as to complete the quick disassembly and assembly of the standardized interface. Multiple sets of side connecting plates 7 configured on a single mounting base 1 can be freely combined within the cross rail system via a limiting base plate 6 to form a grid-like pipe layout that adapts to different area regions.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
