Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and in particular to an assembled geothermal heating structure and a construction method thereof. Background Art
[0002] In the frigid north, geothermal heating has gained widespread popularity and adoption due to its excellent heat dissipation performance and the fact that it doesn't occupy indoor space. This heating method is well-suited to the cold northern climate, creating a warm and comfortable indoor environment and playing a key role in local building heating. Existing geothermal heating systems typically require the installation of an insulation layer and reflective film on the structural floor, followed by the installation of geothermal pipes attached to the insulation panels, and finally, the pouring of concrete to complete the construction. The system works by circulating hot water in the geothermal pipes to transfer heat. The insulation layer reduces heat loss to the floor below, while the reflective film reflects the heat back into the interior, providing heating and meeting people's heating needs. The existing traditional geothermal heating structure has many obvious shortcomings. During construction, a large amount of wet concrete work relies on on-site pouring. The process is complicated and greatly restricted by temperature. Construction in the north during winter or near winter is not only difficult to ensure quality, but also requires high winter measures fees. Concrete maintenance also greatly extends the construction period. Its quality and molding effect are greatly affected by the workers' skills. Problems such as loose fixation of geothermal pipes, irregular laying of insulation layers and reflective films will occur. Due to the lack of professional sound insulation design, the rigid sound bridge causes obvious noise, which reduces living comfort. In addition, the floor heating, load-bearing and sound insulation functions are independent, which increases construction cost and time, makes it difficult to cope with thermal expansion and contraction, easily causes structural deformation and cracking, and cannot be disassembled for secondary use without loss, resulting in serious material waste and low product added value. For this reason, an assembled geothermal heating structure and its construction method are proposed. Summary of the Invention

[0013] A construction method for an assembled geothermal heating structure comprises the following steps: s1. Concrete slab splicing: Slide the two rubber boxes into the interior of the two concrete slabs respectively, rotate the threaded rotating column to drive the guide block to move, so that the rotating ring rotates, and then the connecting rod is pushed to rotate through the rotating rod, causing the sliding block to slide to the outside of the rubber box and into the interior of the concrete slab, completing the splicing of the two concrete slabs; when disassembly is required, rotate the threaded rotating column in the opposite direction to release the lock between the sliding block and the concrete slab, and remove the rubber box.
[0014] s2. Response to thermal expansion and contraction: When the two concrete slabs expand and contract due to temperature changes, the rubber box deforms. At the same time, the V-shaped spring adaptively pushes or pulls the rubber box to buffer the force of temperature changes on the concrete slabs and reduce the risk of damage.

[0016] The present invention provides an assembled geothermal heating structure and a construction method thereof. It has the following beneficial effects: 1. When installing the floor heating panel, the present invention can normally connect the two concrete panels through the fixed steel sheet 2. When it is necessary to deal with thermal expansion and contraction, a docking mechanism is used to slide the fixed steel sheet 1 into the concrete panel, and the threaded column is rotated to drive the relevant components to make the sliding block embedded in the concrete panel to complete the splicing; the reverse operation can be quickly disassembled to achieve lossless installation and disassembly, allowing the panels to be reused multiple times, and the construction speed is fast and the construction period is short. The construction process is simple and convenient, avoiding the problem that the traditional process is affected by the technical level of workers, and the molding effect is good. When thermal expansion and contraction occur, the rubber box deforms and cooperates with the V-shaped spring to adaptively expand and contract, buffering stress, reducing damage to the concrete panel, and extending the service life.
[0017] 2. When installing the heat pipe, the present invention inserts the heat pipe through the Ω-shaped slot opening, and then inserts the heat-conducting insert. Its elastic deformation generates continuous pressure to fix the heat pipe and prevent it from moving. The heat-conducting insert fills the gap and has high thermal conductivity, ensuring efficient and uniform heat transfer, eliminating the traditional cement slurry caulking process, shortening the construction period, and ensuring stable performance and heat transfer efficiency. In extreme cases, the heat-conducting insert can be pried out to facilitate maintenance or replacement of the pipe.
[0018] 3. During installation, the two concrete slabs are normally connected by two fixed steel plates. To prevent thermal expansion and contraction, a docking mechanism is used. The rubber box is slid into the concrete slab, and the threaded column is rotated to drive the relevant components, causing the sliding block to slide into the concrete slab to complete the splicing. Reverse rotation of the threaded column allows for quick disassembly, achieving non-destructive installation and disassembly, allowing the slabs to be used multiple times and easy to operate. When thermal expansion and contraction occur, the rubber box deforms and the V-shaped spring adapts to buffer stress, reducing damage to the concrete slab and extending its service life.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1
[0022] Please see the attached Figure 1 , Attachment Figure 3 and attached Figure 4 , an embodiment of the present invention provides an assembled geothermal heating structure and a construction method thereof, including two concrete slabs 1. The concrete slab 1 is a high-performance concrete bearing layer that can withstand loads and provide a solid foundation for the overall structure. A docking mechanism 2 is provided on the adjacent side of the two concrete slabs 1. The docking mechanism 2 can realize the rapid splicing and disassembly of the two concrete slabs 1, and can cope with the influence of thermal expansion and contraction on the plate. An installation mechanism 4 is provided inside the concrete slab 1. The installation mechanism 4 facilitates the installation and fixation of the heat pipe 42 to ensure efficient heat transfer. A damping and thermal insulation mechanism 3 is provided inside the concrete slab 1. The damping and thermal insulation mechanism 3 can realize sound insulation and thermal insulation functions, and combined with the floor heating function to improve the comfort of the building; The damping and heat-insulating mechanism 3 includes a damping plate 31, the top of which is fixedly connected to the bottom of the concrete slab 1. The damping plate 31 acts as a damping layer, which can absorb vibration energy, cut off rigid sound bridges, and play the role of a sound insulation body. The bottom end of the damping plate 31 is fixedly connected to a counterweight plate 32, which uses its own huge inertia to suppress residual vibration and enhance the sound insulation effect. The bottom end of the counterweight plate 32 is fixedly connected to a reflective membrane 33, which can reflect heat, reduce heat loss, and improve the efficiency of floor heating. The bottom end of the reflective membrane 33 is fixedly connected to an insulation plate 34, which can block heat from transferring downward, further improving the insulation performance. A fixing assembly 35 is provided inside the concrete slab 1. The fixing assembly 35 includes a bolt 351. The external thread of the bolt 351 is connected to the inside of the concrete slab 1. The bolt 351 is used to fix each layer structure to the concrete slab 1 to ensure a stable connection. The external threads of bolt 351 are connected to nut 352, which secures bolt 351 and prevents it from loosening. A recess 353 is defined at the top of concrete slab 1, providing space for nut 352 and preventing it from protruding and causing problems. The bottom end of nut 352 contacts the top of concrete slab 1, ensuring a secure lock.
[0023] Please see the attached Figure 5 To the attached Figure 7The docking mechanism 2 includes two fixed steel sheets 22. The outer parts of the two fixed steel sheets 22 are respectively slidably connected to the top ends of the two concrete slabs 1. The fixed steel sheets 22 provide an installation base for components such as the threaded column 23, which facilitates the splicing and fixation of the concrete slabs 1. An elastic component 29 is provided on the adjacent side of the two fixed steel sheets 22. The elastic component 29 can provide elastic buffering when the concrete slab 1 expands and contracts due to heat, thereby reducing damage to the slab. A rubber box 21 is provided on the adjacent side of the two concrete slabs 1. The rubber box 21 is elastic and can cooperate with the elastic component 29 to absorb the stress generated by thermal expansion and contraction. The internal thread of the fixed steel sheet 22 is connected to the threaded column 23. When the threaded column 23 rotates, it can drive the guide block 24 to move, thereby providing power for the splicing action. The inside of the threaded column 23 is fixedly connected to a guide block 24, and the outside of the guide block 24 is slidably connected to a rotating ring 25. The outside of the rotating ring 25 is fixedly connected to a rotating rod 26. The guide block 24 can guide the rotating ring 25 to rotate, and convert the linear motion of the threaded column 23 into the rotational motion of the rotating ring 25. When the rotating ring 25 rotates, it can drive the rotating rod 26 to swing and transmit power. The end of the rotating rod 26 away from the rotating ring 25 is rotatably connected to a connecting rod 27, and the connecting rod 27 can push the sliding block 28 to slide, so that the sliding block 28 is stuck in the concrete slab 1 to complete the splicing. The end of the connecting rod 27 away from the rotating rod 26 is rotatably connected to the sliding block 28. When the sliding block 28 slides into the concrete slab 1 and the rubber box 21, it can fix the two concrete slabs 1 and the rubber box 21 together to achieve splicing; The elastic component 29 includes an elastic support plate 291, the bottom end of which is detachably connected to the top end of the rubber box 21. A V-shaped spring 292 is fixedly connected to the inside of the rubber box 21. The V-shaped spring 292 has good elastic and retractile properties and can adaptively push or pull the rubber box 21 to buffer the effects of thermal expansion and contraction. A circular hole groove 5 is provided inside the rubber box 21. The circular hole groove 5 provides installation and movement space for the heat pipe 42 to ensure the normal operation of the docking mechanism 2. The outer sliding connection of the sliding block 28 is connected to the inside of the concrete slab 1, and the outer sliding connection of the sliding block 28 is connected to the inside of the rubber box 21. This double sliding connection can ensure that the sliding block 28 effectively fixes the concrete slab 1 and the rubber box 21. The inner sliding connection of the concrete slab 1 is connected to a fixed steel plate 26. The fixed steel plate 26 can realize a rigid connection between the two concrete slabs 1, meet the installation requirements of different construction positions, and improve the stability of the overall structure.
[0024] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 8The mounting mechanism 4 includes a heat pipe 42, the outer portion of which slides within the concrete slab 1. Heat pipe 42 is used to transport hot water or heat transfer media to provide heat for the floor heating system. An Ω-shaped groove 43 is formed within the concrete slab 1. The shape of this groove accommodates both the heat pipe 42 and the heat insert 41, facilitating the installation and securement of the heat pipe 42. The heat insert 41 slides within the Ω-shaped groove 43. This elasticity securely secures the heat pipe 42 within the groove, preventing movement and enhancing heat conduction. The heat insert 41 fits snugly over the outer portion of the heat pipe 42, ensuring efficient heat transfer. The Ω-shaped shape of the heat insert 41 provides excellent elasticity and containment, adapting to the shape of the heat pipe 42 and providing consistent pressure. The outer portion of the heat pipe 42 slides within the circular groove 5, providing space for the heat pipe 42 to pass through and facilitating piping layout. Example 2
[0025] Construction method of assembled geothermal heating structure s1. Splicing of concrete slabs 1: Slide the two rubber boxes 21 into the interior of the two concrete slabs 1 respectively, rotate the threaded rotating column 23, drive the guide block 24 to move, rotate the rotating ring 25, and then push the connecting rod 27 to rotate through the rotating rod 26, causing the sliding block 28 to slide toward the outside of the rubber box 21 and slide into the interior of the concrete slab 1, completing the splicing of the two concrete slabs 1; when disassembly is required, rotate the threaded rotating column 23 in the opposite direction to release the lock between the sliding block 28 and the concrete slab 1, and remove the rubber box 21.
[0026] s2. Response to thermal expansion and contraction: When the two concrete slabs 1 expand and contract due to temperature changes, the rubber box 21 deforms, and the V-shaped spring 292 adaptively pushes or pulls the rubber box 21 to buffer the force exerted by temperature changes on the concrete slabs 1 and reduce the risk of damage.
[0027] s3. Functional integration application: The concrete slab 1 acts as a high-performance concrete bearing layer to bear the load, the damping plate 31 acts as a damping layer to absorb vibration energy and cut off the rigid sound bridge, and the counterweight plate 32 uses inertia to suppress residual vibration. The three form a "mass-spring-mass" model to achieve step-by-step energy attenuation; combined with the reflective membrane 33 and the insulation board 34, the integrated application of floor heating, load-bearing and sound insulation functions is realized.
[0028] Working principle: Under normal circumstances, when construction workers install the floor heating board, the two concrete slabs 1 are connected by the fixed steel sheet 26. When multiple concrete slabs 1 need to avoid thermal expansion and contraction, they are connected through the docking mechanism 2, and the two fixed steel sheets 22 are respectively slid into the interior of the two concrete slabs 1. At this time, by rotating the threaded column 23, the rotation of the threaded column 23 will drive the guide block 24 to rotate, thereby causing the rotating ring 25 to rotate. Through the rotation of the rotating ring 25, the rotating rod 26 pushes the connecting rod 27 to rotate, so that the connecting rod 27 pushes the sliding block 28 to slide toward the outside of the rubber box 21, so that the outside of the sliding block 28 slides into the interior of the concrete slab 1, completing the splicing of the two concrete slabs 1 and achieving the effect of quick splicing. At the same time, rotating the threaded column 23 in the opposite direction can quickly release the locking relationship between the fixed steel sheet 22 and the concrete slab 1, completing the quick disassembly between the concrete slabs 1, non-destructive installation and disassembly, allowing the panels to be used multiple times, and the construction time is fast and the construction period is short. At the same time, the construction process is simple and the installation is convenient, avoiding the defect of the traditional laying process being greatly restricted by the workers' technical level, and the molding effect is better. When the two concrete slabs 1 expand and contract due to heat during use, the rubber box 21 will be deformed, and the V-shaped spring 292 will adaptively push and pull the rubber box 21, thereby reducing the damage to the concrete slab 1 caused by thermal expansion and contraction, and improving the service life of the slab.
[0029] The concrete slab 1 is a high-performance concrete bearing layer responsible for bearing the load. The damping plate 31 is the damping layer, serving as the main body of sound insulation, absorbing vibration energy and cutting off the rigid sound bridge. The counterweight plate 32 in the lower layer uses its huge inertia to suppress residual vibration. This structure ingeniously constitutes the most efficient "mass-spring-mass" model in acoustic engineering. When the impact vibration is received by the upper layer, it is immediately absorbed and dissipated in the middle layer, and finally "suppressed" by the lower layer, achieving step-by-step energy attenuation. At the same time, it is matched with the reflective membrane 33 and the insulation board 34, and finally the floor heating, load-bearing and professional-grade sound insulation functions are combined into one, with the reliable quality of factory prefabrication, which significantly improves the building comfort and product added value.
[0030] When it is necessary to install the heat conducting pipe 42 inside the concrete slab 1, the heat conducting pipe 42 is inserted into the small opening at the top of the Ω-shaped groove 43, and then the heat conducting insert 41 is inserted into the interior of the concrete slab 1. At this time, the elastic deformation of the heat conducting insert 41 itself will generate a continuous pressure, which firmly fixes the heat conducting pipe 42 to the bottom of the groove to prevent it from floating or moving. The heat conducting insert 41 fills all the air gaps between the pipe and the concrete slab 1. Its high thermal conductivity ensures that heat is efficiently and evenly transferred from the pipe to the concrete slab 1, completely eliminating the traditional cement slurry filling process. After laying, the next surface layer construction can be carried out, which greatly compresses the construction period. Compared with manually mixed and filled cement slurry, the prefabricated heat conducting insert 41 has stable performance, ensuring that the heat transfer efficiency of each circuit meets the design standard. At the same time, in extreme cases, the heat conducting insert 41 can be pried out, which is convenient for inspection or replacement of local pipelines.
