Description

Technical Field

[0001] This utility model belongs to the field of building heating, ventilation and air conditioning technology, and specifically relates to an adjustable-distance protective fixing device adapted to heating geothermal pipes. Background Technology

[0002] Geothermal radiant heating is a heating method that uses hot water at a temperature not exceeding 60 degrees Celsius, concealed within a coil system under the floor, to heat the entire floor. The heat is then evenly radiated into the room. This technology successfully solves the problem of limited heat sources in high-ceilinged, large-span, low-windowed buildings, and is a very mature and widely used heating technology. Underfloor heating is comfortable and hygienic. The heat radiates from the floor, and the indoor temperature gradually decreases from bottom to top, resulting in a uniform indoor thermal environment, enhancing indoor comfort, cleanliness, and avoiding dust and volatile odors caused by indoor air convection. The heating process primarily uses radiation, resulting in a reasonable indoor temperature distribution and minimal ineffective heat loss. The heat medium is transported at low temperatures, minimizing heat loss during transport. Under the same comfort conditions, the indoor design temperature can be 2-3 degrees Celsius lower than that of traditional convection heating, saving approximately 15% of heat consumption. Most importantly, it does not occupy usable space. Existing underfloor heating pipes are fixed to the floor using clips and fixing nails, but the following problems exist during fixing:

[0003] 1. When fixing with clips and fixing nails, the clips need to be fastened along the length of the geothermal pipe, and then fixed with fixing nails. However, during fixing, the fixing nails may not be fastened deep enough, causing the clips to loosen and the geothermal pipe to be unstable.

[0004] Second, after the geothermal pipes are fixed, they are filled with filler material. During the filling process, workers may step on the geothermal pipes and filler material. The filler material may squeeze the geothermal pipes, causing them to deform, shift, or crack. Utility Model Content

[0005] To address the problems mentioned in the background section, the purpose of this utility model is to provide an adjustable-distance protective fixing device adapted to geothermal pipes.

[0006] This utility model discloses an adjustable-distance protective fixing device for heating geothermal pipes, comprising a pipe fixing plate, fixing nails, adjusting blocks, and connecting plates; fixing nails are installed at the four bottom corners of the pipe fixing plate, and adjusting blocks are installed on the upper end face of the pipe fixing plate, with the adjusting blocks movably connected to the connecting plates.

[0007] Preferably, the tube fixing piece includes a trapezoidal piece and a limiting plate, with the limiting plate integrally connected to the bottom of the trapezoidal piece.

[0008] Preferably, the two inner sidewalls of the trapezoidal sheet are pressing surfaces, and a multi-diameter clamping channel is formed between the two pressing surfaces.

[0009] Preferably, the pressing surface is provided with several anti-slip grooves.

[0010] Preferably, the limiting plate is provided with a casting groove.

[0011] Preferably, the fixing nail body includes a circular nail, an upper barb, and a lower barb; the upper barb and the lower barb are respectively installed on the outer side wall of the circular nail.

[0012] Preferably, the adjusting block has a locking threaded hole at its center, and a locking bolt is connected inside the locking threaded hole.

[0014] Preferably, the bottom of the connecting plate is provided with a movable groove, the upper side of which is connected to an adjustment groove, and the upper side of the adjustment groove is connected to a countersunk groove.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: The uniform fixing process of the geothermal pipe is achieved through the cooperation of the pipe fixing plate, fixing nail body, adjusting block, and connecting plate. Furthermore, after fixing, the geothermal pipe is less prone to local displacement, effectively protecting the durability of the geothermal pipe's fixed position and improving the overall heating quality. Specific advantages include:

[0016] First, pipe fixing plates are used to fix and protect the geothermal pipes. At the same time, the pipe fixing plates are fixed by fixing nails. After fixing, the pipe fixing plates are stable and durable and will not loosen, thus improving the quality of one-time durable fixing.

[0017] Second, the position of the pipe fixing plate on the connecting plate is adjusted by using an adjusting block, which can be adjusted according to the spacing of the geothermal pipes and has a wide range of applications. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance.

Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0036] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0037] Combination Figures 1 to 9 As shown, this specific embodiment uses pipe fixing plates to fix and protect the geothermal pipes. Fixing nails secure the pipe fixing plates to the ground and the extruded polystyrene board. Specifically, the technical solution includes a pipe fixing plate 1 and fixing nails 2. Fixing nails 2 are installed at the four corners of the bottom of the pipe fixing plate 1. The pipe fixing plate 1 can fix the geothermal pipe 5. After fixing, the fixing nails 2 secure the pipe fixing plate 1 to the ground or the extruded polystyrene board. Figure 2 As shown, the pipe fixing piece 1 includes a trapezoidal piece 1-1 and a limiting plate 1-2. The bottom of the trapezoidal piece 1-1 is integrally connected to the limiting plate 1-2. The two inner sidewalls of the trapezoidal piece 1-1 are pressing surfaces, and a multi-diameter clamping channel is formed between the two pressing surfaces. The two pressing surfaces respectively contact the sidewalls of the geothermal pipe 5, which can fix the geothermal pipe 5. The limiting plate 1-2 has a casting groove 1-21, which can realize the casting of cement mortar. To achieve subsequent filling, the fixing nail body 2 includes a circular nail 2-1, an upper barb 2-2, and a lower barb 2-3. The outer side wall of the circular nail 2-1 is respectively equipped with the upper barb 2-2 and the lower barb 2-3. The circular nail 2-1 can be fixed on the ground, while the upper barb 2-2 and the lower barb 2-3 are used to fix it inside the extruded board. When fixed on the ground, the lowest point of the lower barb 2-3 is the limiting end, which can support the ground and prevent the circular nail 2-1 from continuing to descend.

[0038] Based on the above, combined with Figure 3 As shown in the figure, in order to improve the stability of the geothermal pipe after it is fixed and to prevent the geothermal pipe from shifting, several anti-slip grooves 1-11 are provided on the lower pressure surface. The anti-slip grooves 1-11 can prevent the geothermal pipe 5 from slipping, so that the geothermal pipe 5 can be stably fixed.

[0039] Combination Figure 1As shown, in this specific embodiment, in order to improve the stability of the geothermal pipe after fixing, and to control the flatness of the filling and the laying of the mesh in the later stage, the following technical solution is adopted: including an adjusting block 3 and a connecting plate 4; the adjusting block 3 is installed on the upper end face of the pipe fixing piece 1, and the adjusting block 3 is movably connected to the connecting plate 4. The position of the pipe fixing piece 1 fixed on the connecting plate 4 is adjusted by the adjusting block 3. The connecting plate 4 can improve the stability of the pipe fixing piece 1, and the connecting plate 4 can improve the flatness, which is convenient for the laying of the mesh in the later stage. The center position of the adjusting block 3 is open. A locking threaded hole 3-1 is provided, and a locking bolt 3-2 is connected inside the locking threaded hole 3-1. The locking bolt 3-2 can be connected inside the locking threaded hole 3-1, which can fix the adjusting block 3 to the connecting plate 4. The adjusting block 3 is a regular polygon, such as a regular square, regular hexagon, regular octagon, etc. The regular polygon can adjust the fixing direction. When fixed at an angle, the connecting plate 4 can be fixed at an angle. When fixed at an angle, a regular hexagon, regular octagon, or a regular polygon with more or fewer sides is selected according to the fixing angle. Figure 5 , Figure 6 As shown, the bottom of the connecting plate 4 is provided with a movable groove 4-1, which enables the installation and movement of the adjusting block 3. The upper side of the movable groove 4-1 is connected to an adjusting groove 4-2, which enables the insertion of the locking bolt 3-2 for easy connection with the adjusting block 3. The upper side of the adjusting groove 4-2 is connected to a countersunk groove 4-3, which enables the installation and movement of the adjusting block 3.

[0040] The working process of the geothermal pipe 5 when it is fixed on the ground in this specific embodiment is as follows:

[0041] Combination Figure 7 As shown, the area where geothermal heating needs to be installed is cleaned, then a reflective film is laid on the ground, followed by the geothermal pipe 5. During installation, the geothermal pipe 5 is restricted by the pipe fixing plate 1, and the two downward pressing surfaces of the trapezoidal plate 1-1 are used to press the geothermal pipe 5 down. The pipe is then fixed to the ground by the circular nail 2-1 of the fixing nail body 2. After fixing, the bottom of the barbs 2-3 contacts the ground, providing a limit and preventing the circular nail 2-1 from descending further, thus preventing the geothermal pipe from being squeezed and damaged. Once the pipe fixing plate 1 is fixed, its combination... Figure 9 As shown, the connecting plate 4 is connected to the adjusting block 3. The connecting plate 4 can be connected along the length of the geothermal pipe 5 or along the width of the geothermal pipe 5. The connecting plate 4 can fix several geothermal pipes together and also protect the geothermal pipe 5. The adjusting block 3 is fixed to the connecting plate 4 by locking bolts 3-2. After fixing, a mesh is laid on the connecting plate 4 and filled with cement mortar.

[0042] In this specific embodiment, the connecting plate 4 can be cut to size according to the size of the room to be laid. At the same time, in order to improve stability when fixing, when fixing several geothermal pipes 5, the connecting plate 4 is arranged into a long strip along the width direction of the geothermal pipes 5, and the two ends of the long strip are in contact with the two walls. This can improve the stability of fixing, and even if the geothermal pipes 5 are stepped on during construction, the geothermal pipes 5 are not easy to shift or loosen.

[0043] The working process of the geothermal pipe 5 fixed on the extruded polystyrene board in this specific embodiment is as follows:

[0044] Combination Figure 8 As shown, the area where geothermal heating needs to be installed is cleaned, a reflective film is laid on the ground, followed by an extruded polystyrene (XPS) board. The geothermal pipes 5 are then laid into grooves in the XPS board, which secure them in place. Pipe fixing pieces 1 are used to fix the geothermal pipes 5. When the pipe fixing pieces 1 are fixed, their limiting plates 1-2 support them on the XPS board, providing both positioning and support. Next, fixing nails 2 are fixed to the XPS board. At this point, the upper barbs 2-2 and lower barbs 2-3 engage within the XPS board, ensuring stable fixing of the pipe fixing pieces 1. Then, combined with… Figure 9 As shown, the connecting plate 4 is used to fix the adjusting block 3 on the pipe fixing plate 1. The connecting plate 4 is used to fix and protect the geothermal pipe 5. The connecting plate 4 can fix the geothermal pipe 5 along its length or width. After the fixing is completed, a mesh is laid on the connecting plate 4, and then cement mortar is poured.
