Description

Technical Field

[0001] This utility model relates to the field of underfloor heating pipe installation technology, specifically to a fixing device for underfloor heating pipes. Background Technology

[0002] During the construction of an underfloor heating system, the quality of the pipe fixing directly affects the system's heat dissipation efficiency, service life, and safety. Therefore, the pipe fixing device is one of the core auxiliary components in underfloor heating construction. Currently, the mainstream pipe fixing methods on the market are mainly divided into two categories: one is the traditional pin-clamp fixing method, which involves manually driving plastic pins directly into the ground and using the pins' grooves to hold the pipes; the other is the use of prefabricated fixing brackets with pre-set pipe clamps at fixed intervals, where the pipes are inserted into the clamps during construction to complete the fixing. However, traditional pin-mounted systems rely entirely on the experience of installers to judge the spacing, requiring repeated measurements with a tape measure before nailing. This is not only inefficient but also prone to uneven spacing due to hand tremors and visual deviations. Excessive spacing in some areas can create heat loss zones, while insufficient spacing increases pipe usage and construction costs, and in severe cases, can even affect the water circulation efficiency of the underfloor heating system. While prefabricated fixing brackets have pre-set pipe clamp spacing, this spacing cannot be flexibly adjusted according to the actual underfloor heating design of the house. If the design requires localized densification or widening of the spacing, the prefabricated brackets cannot be adapted and must be cut and reassembled, further increasing construction complexity and material waste. Utility Model Content

[0003] The purpose of this utility model is to provide a fixing device for underfloor heating pipes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for underfloor heating pipes, comprising a base plate, a track plate fixedly connected to the surface of the base plate, the track plate being T-shaped, and multiple sets of arrayed support seats slidably connected to the surface of the track plate, the support seats having a groove on their surface, a clamping assembly being provided inside the groove, the clamping assembly including a slider, the slider being slidably connected inside the groove, two sets of sliders being symmetrically arranged, the two sets of sliders being threadedly connected by a bidirectional threaded rod, the bidirectional threaded rod passing through and rotatably connected to the surface of the support seat, a rotating wheel fixedly connected to the end of the bidirectional threaded rod, and an arc-shaped plate fixedly connected to the top of the slider.

[0005] Preferably, the surface of the track plate is provided with a groove, and a scale plate is fixedly connected inside the groove.

[0006] Preferably, multiple sets of arrayed rubber protrusions are fixedly connected to the inner wall of the arc-shaped plate.

[0007] Preferably, the bearing seat is C-shaped, and both ends protrude inwards to engage with the protrusions of the track plate.

[0008] Preferably, the side wall of the bearing seat has a through hole, and a locking bolt is threaded into the through hole.

[0009] Preferably, the bottom plate has ground nail holes at both ends.

[0010] Compared with the prior art, this utility model provides a fixing device for underfloor heating pipes, which has the following beneficial effects: 1. The fixing device for this underfloor heating pipe achieves a stable connection between the device and the ground through the combination of the mounting structure with the base plate nail holes and the T-shaped track plate. Furthermore, the sliding support on the track plate surface allows for flexible adjustment of the underfloor heating pipe spacing. Simultaneously, the scale plate within the groove clearly displays the coordinates of the support position, eliminating the need for repeated manual measurements during construction; positioning can be done directly according to the scale, significantly reducing spacing deviations and effectively improving the accuracy and efficiency of underfloor heating pipe installation. This solves the problems of inconvenient spacing adjustment and error-prone manual measurement reliance in traditional fixing devices.

[0011] 2. The fixing device for this underfloor heating pipe uses a symmetrical slider and an arc-shaped plate driven by a bidirectional threaded rod, along with rubber protrusions on the inner wall of the arc-shaped plate. This allows it to accommodate underfloor heating pipes of different diameters, eliminating the need for frequent replacement of fixing parts of different specifications and significantly reducing construction costs. The rubber protrusions simultaneously provide anti-slip and anti-wear effects, preventing the underfloor heating pipe from sliding during thermal expansion and contraction, reducing rigid friction between the outer wall of the pipe and the fixing parts, extending the service life of the underfloor heating pipe, and overcoming the shortcomings of traditional fixing parts, such as poor adaptability and easy damage to the pipe.

[0014] like Figures 1-3As shown, this utility model provides a technical solution: a fixing device for underfloor heating pipes, including a base plate 1, with ground nail holes 11 at both ends of the surface of the base plate 1. Ground nails or expansion screws are driven into the ground nail holes 11 at both ends of the base plate 1 to make the base plate 1 fit tightly with the ground and ensure the overall stability of the device.

[0015] A track plate 2 is fixedly connected to the surface of the base plate 1. The track plate 2 is T-shaped and has a groove 21 on its surface. A scale plate 22 is fixedly connected inside the groove 21. The scale plate 22 can intuitively display the position coordinates of the bearing seat 3, which is convenient for construction personnel to accurately position according to the design requirements and avoid manual measurement errors.

[0016] The surface of the track slab 2 is slidably connected with multiple arrays of bearing seats 3. The bearing seats 3 are C-shaped, and both ends protrude inward to engage with the protrusions of the track slab 2. The bearing seats 3 and the track slab 2 form a snap-fit ​​sliding fit, which can move freely along the length of the track slab 2, flexibly adjust the laying spacing of the underfloor heating pipes, and the number of bearing seats 3 can be added to the end of the track slab 2 according to the laying requirements of the underfloor heating pipes.

[0017] The side wall of the bearing seat 3 has a through hole, and a locking bolt 31 is threaded into the through hole. When the bearing seat 3 moves to the target position, the locking bolt 31 on its side wall is tightened. The end of the locking bolt 31 presses against the side wall of the track plate 2, and the bearing seat 3 is fixed by friction to prevent displacement when the underfloor heating pipe is laid later.

[0018] A groove 32 is formed on the surface of the support base 3. A clamping assembly 4 is installed inside the groove 32. The clamping assembly 4 includes a slider 41, which is slidably connected inside the groove 32. Two sets of sliders 41 are symmetrically arranged and are threadedly connected to each other by a bidirectional threaded rod 42. The bidirectional threaded rod 42 passes through and is rotatably connected to the surface of the support base 3. A rotating wheel 43 is fixedly connected to the end of the bidirectional threaded rod 42, and an arc-shaped plate 44 is fixedly connected to the top of the slider 41. By rotating the rotating wheel 43, the bidirectional threaded rod 42 rotates synchronously. Since the two sets of sliders 41 are respectively engaged with the left-hand thread and the right-hand thread of the bidirectional threaded rod 42, the rotation of the bidirectional threaded rod 42 will drive the two sets of sliders 41 to move in opposite directions along the groove 32, thereby adjusting the distance between the two sets of arc-shaped plates 44. By adjusting the distance between the arc-shaped plates 44, different diameter underfloor heating pipes can be accommodated without replacing different specifications of fasteners, thus reducing construction costs.

[0019] Multiple sets of arrayed rubber protrusions 45 are fixedly connected to the inner wall of the arc-shaped plate 44. The rubber protrusions 45 increase the friction with the outer wall of the underfloor heating pipe, preventing the underfloor heating pipe from sliding during thermal expansion and contraction. At the same time, they prevent the arc-shaped plate 44 from directly contacting the underfloor heating pipe, reducing wear on the outer wall of the pipe and extending the service life of the underfloor heating pipe.

[0020] In this utility model, during use, the base plate 1 is first placed flat on the corresponding position of the ground to be constructed according to the design direction of the underfloor heating pipe laying. Then, through the pre-set nail holes 11 at both ends of the base plate 1, nails are driven into the ground or expansion bolts are screwed in until the base plate 1 is completely and tightly attached to the ground, laying a stable foundation for the subsequent laying of underfloor heating pipes.

[0021] According to the required spacing of the underfloor heating pipes in the design drawings, observe the scale plate 22 in the groove 21 of the track plate 2, and slide multiple sets of bearing seats 3 along the length of the T-shaped track plate 2 to the target coordinate position. After adjusting the position of each bearing seat 3, immediately tighten the locking bolts 31 on its side wall, so that the ends of the locking bolts 31 are tightly pressed against the side wall of the track plate 2. The bearing seat 3 is fixed by friction, preventing the bearing seat 3 from shifting during subsequent operations and avoiding laying deviations caused by manual measurement errors. If the actual laying length requires an increase in the number of underfloor heating pipes, new bearing seats 3 can be added directly from the end of the track plate 2, and the positioning and tightening steps can be repeated.

[0022] The underfloor heating pipe to be laid is placed between the two sets of arc-shaped plates 44 of each set of bearing seats 3. Based on the actual diameter of the underfloor heating pipe, the rotating wheel 43 at the end of the bidirectional threaded rod 42 on the surface of the bearing seat 3 is rotated. Since the left-hand and right-hand threads of the bidirectional threaded rod 42 respectively engage with the two sets of sliders 41, the rotation of the rotating wheel 43 will drive the bidirectional threaded rod 42 to rotate synchronously, thereby driving the two sets of sliders 41 to move towards each other along the sliding groove 32, gradually reducing the distance between the two sets of arc-shaped plates 44 until the rubber protrusions 45 on the inner wall of the arc-shaped plate 44 are tightly fitted against the outer wall of the underfloor heating pipe. The rubber protrusions 45 increase the friction with the underfloor heating pipe, preventing the pipe from slipping due to thermal expansion and contraction during long-term use. Simultaneously, it avoids direct rigid contact between the arc-shaped plate 44 and the underfloor heating pipe, reducing wear on the outer wall of the pipe and extending its service life.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
