Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a construction method for an overhead ground structure of a building. Background Art

[0002] Traditional floor decoration methods include multiple processes, such as leveling layer, floor heating concrete layer, tile bonding mortar layer, etc. These wet construction layers not only increase the difficulty of construction, but also greatly increase the consumption of materials. At the same time, the multi-layer structure leads to a significant increase in building loads, posing a potential threat to the safety and stability of the building structure.

[0003] Wet work accounts for a high proportion in floor decoration, and construction efficiency is deeply affected by multiple factors such as manual skills, weather conditions, and construction environment, resulting in slow construction speed. In addition, wet work is prone to generate a large amount of dust, which not only seriously endangers the health of workers, but also causes significant pollution to the surrounding environment, violating the principle of green construction.

[0004] In traditional floor decoration, the insulation layer is usually set inside the concrete layer. When the floor heating is activated, the heat needs to pass through the thick concrete layer to be transferred to the floor surface layer, and then the floor surface layer radiates heat to the room. This heat conduction method is inefficient, resulting in high energy consumption and slow response of the floor heating system, which is not conducive to achieving the goal of energy conservation and emission reduction. At the same time, the thermal inertia of the concrete layer is large, making the indoor temperature adjustment inflexible and difficult to meet the dual needs of modern buildings for comfort and energy efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a construction method for an overhead ground structure of a building, so as to separate pipelines from structures, avoid chiseling of the main structure due to renovation or maintenance of pipelines, and ensure the integrity and reliability of the structure.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0007] A construction method for an overhead ground structure of a building, the method comprising:

[0008] Clean the dust and debris on the surface of the base layer, remove the concave and convex parts of the base layer surface, fill the voids, make the base layer surface flat and free of defects, and obtain the base layer treatment result;

[0009] According to the results of the base treatment, the elevation control line is popped up along the wall, and the elevation of the structural plate is checked by pulling the wire to make it consistent with the decoration thickness, providing positioning for the installation of the overhead module and obtaining the positioning result of the line setting;

[0010] According to the results of the positioning, the overhead panels are installed according to the overhead panel layout drawing. During the installation process, the spacing between the anchor bolts is kept within 400mm to obtain the preliminary installed overhead module.

[0011] According to the preliminarily installed overhead modules, use the leveling tool to level the overhead panels and inject glue to fix the anchor bolts; at the same time, check and repair the bumps of the aluminum foil reflective film to obtain the adjusted and fixed overhead modules;

[0012] According to the adjusted and fixed overhead modules, the floor heating pipes are laid in the installed overhead layer grooves, so that the floor heating pipes fit tightly with the grooves to obtain the floor heating pipe system;

[0013] According to the floor heating pipe system, a pressure test is carried out on the indoor floor heating system to ensure that there is no leakage in the floor heating system and the pressure is stable. The slab surface construction is carried out on the elevated floor to complete the final structure of the building's elevated ground.

[0014] Furthermore, according to the results of the base treatment, the elevation control line is popped up along the wall, and the elevation of the structural plate is checked by pulling the wire to make it consistent with the decoration thickness, providing positioning for the installation of the overhead module, and obtaining the positioning results of the line laying, including:

[0015] Confirm that the surface of the base layer is flat and has no defects, and enter the line-laying and positioning mode;

[0016] Prepare the wire laying positioning tools, including laser transmitter and wire pulling tools, and plan the wire laying path according to the design drawings;

[0017] Manually adjust the position and angle of the laser transmitter according to the elevation parameters and wall position on the design drawing;

[0018] Start the laser transmitter, pop up a laser line along the edge of the wall to form an elevation control line, and use the wire pulling tool to check the elevation of the structural plate along the elevation control line;

[0019] Compare the elevation of the structural plate with the decoration thickness parameters on the design drawing to determine whether there is a deviation. If there is a deviation, manually adjust the position of the laser transmitter again, re-pop up the elevation control line, and re-check until the data matches. Record the elevation data and position information as the result of line laying and positioning.

[0020] Furthermore, the elevation of the structural plate is compared with the decoration thickness parameters on the design drawing to determine whether there is a deviation. If there is a deviation, the position of the laser transmitter is manually adjusted again, the elevation control line is re-popped up, and re-checked until the data matches, and the elevation data and position information are recorded as the result of line positioning, including:

[0021] Compare the actual elevation of the structural plate with the decoration thickness parameters on the design drawing and calculate the deviation value ΔH = (H + H a )-(T+T t +T c), where ΔH represents the difference between the actual elevation and the design drawing; H represents the actual elevation; H a Indicates the elevation adjustment coefficient; T indicates the decoration thickness on the design drawing; T t Indicates the allowable deviation of decoration thickness; T c represents the weight parameter;

[0022] If there is a deviation, that is, ΔH≠0, manually adjust the position of the laser transmitter again according to the deviation value, pop up the elevation control line again, and perform another check;

[0023] Repeat the process of comparison, adjustment and verification until the deviation value ΔH approaches zero, that is, ΔH≈0, and record the elevation data and position information as the result of line setting and positioning.

[0024] Further, according to the results of the positioning, the overhead panels are installed according to the overhead panel layout drawing. During the installation process, the spacing between the anchor bolts is not more than 400 mm, and the preliminary installed overhead module is obtained, including:

[0025] Receive and review the results of the layout and positioning, including elevation data and location information;

[0026] According to the overhead panel layout drawing, prepare overhead panels of corresponding specifications and quantity, as well as installation tools, including anchor bolts, wrenches, and screwdrivers, and mark the starting point for the overhead panel installation on the wall;

[0027] Starting from the starting point, place the overhead panels one by one at the predetermined positions according to the overhead panel layout diagram. When placing the overhead panels, ensure that the overhead panels are parallel to the wall and the edges are aligned with the elevation control line;

[0028] At the four corners of the overhead plate, the overhead plate is fixed to the ground using anchor bolts so that the spacing between the anchor bolts does not exceed 400 mm, thereby obtaining a preliminarily installed overhead module.

[0029] Further, according to the initially installed overhead module, the overhead plate is leveled using a leveling tool, and the anchor bolts are fixed by injecting glue; at the same time, the bumps of the aluminum foil reflective film are checked and repaired, and the adjusted and fixed overhead module is obtained, including:

[0030] Receive and inspect the preliminarily installed overhead modules to ensure that the overhead panels have been installed in accordance with the layout results and the overhead panel layout drawing;

[0031] Prepare leveling tools, including a level, adjustment shims, and glue injection materials for fixing anchor bolts, including epoxy resin glue;

[0032] Use a level to check the levelness of each overhead board. For uneven areas, place adjustment pads under the anchor bolts or adjust the height of the anchor bolts to level them, and inject glue into each anchor bolt.

[0033] Use a glue injection gun to inject epoxy resin glue into the holes of the anchor bolts, and check whether the aluminum foil reflective film on the surface of the overhead board is bumped, damaged or missing. If the aluminum foil reflective film is bumped, damaged or missing, use aluminum foil tape to repair the reflective film to obtain an adjusted and fixed overhead module.

[0034] Further, according to the adjusted and fixed overhead modules, the floor heating pipes are laid in the installed overhead layer grooves so that the floor heating pipes fit tightly with the grooves, thereby obtaining a floor heating pipe system, including:

[0035] Receive the adjusted and fixed overhead modules, and prepare a sufficient number of floor heating pipes according to the construction drawings and floor heating pipe specifications. At the same time, prepare tools for laying floor heating pipes, including scissors, pipe clamps, and pipe benders;

[0036] According to the design drawings, determine the starting point for laying the floor heating pipe in the groove of the overhead layer and mark the positioning line;

[0037] Starting from the starting point, place the floor heating pipes section by section into the grooves of the overhead layer, so that the floor heating pipes fit tightly into the grooves. During the laying process, keep the floor heating pipes straight to ensure smooth water flow and the normal operation of the floor heating system.

[0038] Use pipe clamps or straps to fix the floor heating pipes in the grooves of the overhead layer to prevent movement or displacement during use, and inspect the floor heating pipes to make sure that they are laid flat and fit tightly in the grooves without any looseness, hanging or twisting, to obtain the floor heating pipe system.

[0039] Furthermore, according to the floor heating pipe system, the indoor floor heating system is pressure tested to ensure that the floor heating system has no leakage and the pressure is stable. The plate surface layer is constructed on the overhead layer to complete the final structure of the building overhead floor, including:

[0040] According to the pressure test standards for floor heating systems, prepare pressure test equipment, including pressure pumps and pressure gauges;

[0041] Connect the pressure pump to the water inlet of the floor heating system, close the exhaust valve and drain valve, start pressure pumping, and gradually increase the system pressure until the preset test pressure is reached;

[0042] During the pressure test, observe the reading of the pressure gauge and check whether there are any leaks at the joints, valves and connectors of the floor heating pipe system. If there is any leak, stop the pressure test immediately, mark the leak location and repair it.

[0043] After the repair is completed, re-test the pressure until the system is leak-free and the pressure is stable, and then start preparing materials for the panel surface construction, including floor tiles, wooden floors, carpets and corresponding auxiliary materials, including adhesives and caulking agents;

[0044] The slab surface layer is constructed on the elevated layer of the floor heating system. The slab materials are laid one by one on the elevated layer in a certain laying order and pattern. During the laying process, the gaps between the slabs are made uniform, and adhesives or caulking agents are used to fix and fill the gaps to complete the final structure of the building's elevated floor.

[0045] Furthermore, the overhead plate is provided with a plurality of overhead supports fixed on the ground to separate the pipeline from the structural plate;

[0046] A pressed membrane shell is installed on the overhead board, and a groove is designed on the surface of the pressed membrane shell for laying and fixing the floor heating pipes and evenly dissipating the heat to the ground to achieve the floor heating function. At the same time, it serves as a protective layer to prevent the external environment from causing damage to the floor heating pipes and the underlying structure.

[0047] Furthermore, floor heating pipes are laid in the grooves of the pressed membrane shell, and heat is transferred to the ground through circulating hot water or hot air to increase the indoor temperature, thereby ensuring uniform distribution of the indoor temperature.

[0048] Furthermore, an aluminum foil reflective film is laid above the pressed membrane shell and between the composite bricks to enhance the thermal insulation and heat insulation performance of the ground;

[0049] Composite bricks are laid on top of the aluminum foil reflective film. The composite bricks serve as the final laying layer of the overhead floor system and are in direct contact with users.

[0050] The above solution of the present invention includes at least the following beneficial effects:

[0051] By eliminating the wet construction layers such as the leveling layer, floor heating concrete layer, and tile bonding mortar layer in the traditional floor, the floor structure is significantly simplified, the weight of the decoration layer is reduced, thereby reducing the load on the building structure and improving the safety and stability of the building. Each structural layer is industrialized and assembled on site, which greatly improves the construction efficiency and shortens the construction period. At the same time, due to the reduction of wet operations, the noise and dust pollution during the construction process are reduced, the working environment of the workers is improved, and it meets the requirements of green construction and environmental protection.

[0052] Grooves for laying floor heating pipes are pressed out on the overhead board to directly install the floor heating pipes, eliminating the traditional floor heating concrete layer, thereby improving the heat transfer efficiency of the floor heating pipes. This design enables the floor heating system to heat the indoor space faster and more evenly, reducing energy consumption and improving energy conservation and emission reduction effects. The overhead ground structure allows the pipelines to be separated from the structure, facilitating the subsequent laying, maintenance and replacement of pipelines, avoiding the need to chisel the main structure due to renovation or maintenance of pipelines, and protecting the integrity and reliability of the structure. The overhead board is leveled using a leveling tool, and the anchor bolts are fixed with glue to ensure the flatness of the ground system. At the same time, the laying of aluminum foil reflective film enhances the thermal insulation performance of the ground and improves the comfort of living. The surface layer construction of the overhead ground structure can select plate materials of different materials and patterns according to actual needs, such as floor tiles, wooden floors, carpets, etc., to meet the decoration needs of different styles and functions, and improve the beauty and practicality of the building.

[0057] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0058] like Figure 1 As shown, an embodiment of the present invention provides a construction method for an overhead ground structure of a building, the method comprising the following steps:

[0059] Step 11, clean the dust and debris on the surface of the base layer, remove the concave and convex parts of the surface of the base layer, fill the voids, make the surface of the base layer flat and free of defects, and obtain the base layer processing result;

[0060] Step 12: According to the base treatment result, the elevation control line is popped up along the wall, and the elevation of the structural plate is checked by pulling the wire to make it consistent with the decoration thickness, so as to provide positioning for the installation of the overhead module and obtain the positioning result of the line setting;

[0061] Step 13, according to the positioning result of the wire laying, the overhead board is installed according to the overhead board layout drawing. During the installation process, the spacing between the anchor bolts does not exceed 400 mm, and the overhead module is preliminarily installed;

[0062] Step 14: According to the preliminarily installed overhead module, use a leveling tool to level the overhead plate, and inject glue to fix the anchor bolts; at the same time, check and repair the bumps of the aluminum foil reflective film to obtain an adjusted and fixed overhead module;

[0063] Step 15, according to the adjusted and fixed overhead module, laying the floor heating pipe in the installed overhead layer groove, so that the floor heating pipe fits tightly with the groove, and obtaining the floor heating pipe system;

[0064] Step 16, based on the floor heating pipe system, conduct a pressure test on the indoor floor heating system to ensure that the floor heating system has no leakage and the pressure is stable, and perform slab surface construction on the elevated floor to complete the final structure of the building's elevated floor.

[0065] In an embodiment of the present invention, the dust and debris on the surface of the base layer are thoroughly cleaned, and the concave and convex parts are removed and the holes are filled, thereby ensuring that the surface of the base layer is flat and free of defects. The stability and accuracy of the installation of the overhead module are improved, and installation problems caused by the unevenness of the base layer are avoided. The elevation control line is popped up along the wall, and the elevation of the structural plate is checked by pulling the wire to make it consistent with the thickness of the decoration, providing accurate positioning for the installation of the overhead module. This step ensures that the installation position of the overhead module is accurate and avoids installation deviation problems caused by inaccurate positioning. The overhead plate is installed according to the overhead plate layout diagram, and the spacing of the anchor bolts is strictly controlled to not exceed 400mm, ensuring the stability of the overhead module. This installation method not only improves the load-bearing capacity of the overhead ground, but also enhances its overall stability.

[0066] Use the leveling tool to level the overhead board, inject glue to fix the anchor bolts, and check and repair the bumps of the aluminum foil reflective film to ensure the flatness and firmness of the overhead module. This step effectively avoids the problems of ground ups and downs and looseness caused by uneven or loose fixation of the overhead board, and improves the service life and comfort of the floor. Lay the floor heating pipe in the groove of the installed overhead layer so that the floor heating pipe fits tightly with the groove, ensuring the stability and heat transfer efficiency of the floor heating pipe system. This laying method not only simplifies the installation process of the floor heating pipe, but also improves the overall performance of the floor heating system, providing a more uniform and comfortable heating effect for the room. Perform a pressure test on the indoor floor heating system to ensure that the floor heating system has no leakage and stable pressure, which provides a guarantee for the normal operation of the floor heating system. At the same time, the plate surface layer is constructed on the overhead layer to complete the final structure of the building's overhead floor. This step not only ensures the reliability and safety of the floor heating system, but also improves the aesthetics and practicality of the floor, meeting the requirements of different decoration styles and functions.

[0067] In a preferred embodiment of the present invention, the above step 11, cleaning the dust and debris on the surface of the base layer, removing the concave and convex parts of the surface of the base layer, filling the voids, making the surface of the base layer flat and free of defects, and obtaining the base layer processing result, may include:

[0068] Prepare tools and materials, such as a broom, a spatula, and a wire brush (for removing raised parts of the base surface). Filling materials (such as cement mortar, putty powder, etc., selected according to the base material and the size of the hole). First, use a broom or vacuum cleaner to thoroughly clean the base surface to remove all dust, debris, and other debris. Next, use a spatula or wire brush to carefully remove raised parts of the base surface, such as old paint, residues, etc., to ensure a smooth surface. For larger holes or depressions, use filling materials to fill them and scrape them flat with a scraper to ensure that the filled surface is flush with the surrounding base.

[0069] Assume that the base is a concrete floor with many spots of dust, gravel, and several small holes on the surface. First, the construction workers use a vacuum cleaner to clean the dust and gravel on the surface of the floor. Then, they use a spatula to scrape away the raised parts of the surface, such as the remaining concrete blocks. For the hollow parts, they choose cement mortar with good compatibility with concrete to fill them, and use a scraper to carefully scrape them flat to ensure that the filled surface is flush with the surrounding concrete. Inspection tools, level ruler, ruler or laser distance meter (used to check the flatness of the base surface). After cleaning and filling, use a level ruler, ruler or laser distance meter to check the flatness of the base surface. If there are still uneven places, use the filling material to fill or polish again until the entire base surface is flat and defect-free.

[0070] After filling the holes, the construction workers used a laser rangefinder to conduct a comprehensive inspection of the floor surface. They found that there were still tiny depressions in several places. So they used cement mortar to fill these places again and used scrapers and sandpaper to polish until the entire floor surface became completely flat.

[0071] In a preferred embodiment of the present invention, the above step 12, according to the base treatment result, pops up the elevation control line along the wall, and checks the elevation of the structural plate by pulling the wire to make it consistent with the decoration thickness, provides positioning for the installation of the overhead module, and obtains the positioning result of the line setting, which may include:

[0072] Step 121, confirm that the surface of the base layer is flat and has no defects, and enter the line setting and positioning mode;

[0073] Step 122, according to the design drawings, prepare the wire laying positioning tools, including the laser transmitter and the wire pulling tool, and plan the wire laying path;

[0074] Step 123, manually adjusting the position and angle of the laser transmitter according to the elevation parameters and the wall position on the design drawing;

[0075] Step 124, start the laser transmitter, pop out a laser line along the edge of the wall to form an elevation control line, and use a wire drawing tool to check the elevation of the structural plate along the elevation control line;

[0076] Step 125, compare the elevation of the structural plate with the decoration thickness parameters on the design drawing to determine whether there is a deviation. If there is a deviation, manually adjust the position of the laser transmitter again, pop up the elevation control line again, and re-check until the data matches, record the elevation data and position information as the result of line positioning.

[0077] In an embodiment of the present invention, according to the design drawings, the construction personnel prepare the tools required for line positioning, including a laser transmitter, a wire drawing tool (such as an ink line box, a tape measure, etc.), and plan the line laying path according to the drawings. The construction personnel manually adjust the position and angle of the laser transmitter according to the elevation parameters and the wall position on the design drawings, so that the laser line emitted by it can accurately form an elevation control line along the edge of the wall. The construction personnel start the laser transmitter to emit a stable laser line. The laser line is projected along the edge of the wall to form a clear elevation control line. This line serves as the height reference for the installation of the overhead module. Use a wire drawing tool (such as an ink line box) to mark the structural plate along the elevation control line. Use a tape measure or other measuring tool to measure the difference between the marked point on the structural plate and the elevation parameter on the design drawing. Compare the actual measured structural plate elevation with the decoration thickness parameter on the design drawing to determine whether there is a deviation. If there is a deviation, the construction personnel need to manually adjust the position of the laser transmitter again, re-pop up the elevation control line, and re-check. Repeat the process of comparison, adjustment, and verification until the measured data is completely consistent with the design drawing. Record the elevation data and location information at this time as the result of line laying and positioning.

[0078] In an embodiment of the present invention, by confirming that the surface of the base layer is flat and free of defects, and strictly entering the laying-out and positioning mode, an accurate benchmark is provided for the installation of the overhead module. This improves the accuracy of the installation, reduces the installation deviation caused by uneven base layer or inaccurate positioning, and thus improves the construction efficiency. Prepare the laying-out and positioning tools according to the design drawings, and plan the laying-out path to ensure the systematicness and standardization of the laying-out process. By using a laser transmitter to pop out a laser line along the edge of the wall to form an elevation control line, and then use the wire pulling tool for verification, the elevation of the structural plate can be accurately controlled to match the decoration thickness parameters. This ensures the consistency of the decoration thickness of the entire overhead ground system and improves the overall aesthetics of the ground. During the laying-out and positioning process, the deviation is discovered and corrected in time by repeatedly verifying the elevation of the structural plate with the decoration thickness parameters on the design drawings. This active control method effectively reduces rework caused by deviations, reduces construction costs, and shortens construction period.

[0079] Accurate line-setting and positioning results provide a reliable positioning basis for the installation of overhead modules, ensuring the stable installation of the modules. This not only improves the construction quality, but also enhances the stability of the overhead ground system, thereby increasing the load-bearing capacity and service life of the ground, and providing protection for the safety of users. Recording line-setting and positioning results such as elevation data and location information provides an accurate reference for construction (such as the installation of overhead modules, the laying of floor heating pipes, etc.). At the same time, these records are also an important basis for construction acceptance, which helps to ensure that the construction quality meets the design requirements and facilitates the traceability and evaluation of project quality.

[0080] In a preferred embodiment of the present invention, the above step 125 compares the elevation of the structural plate with the decoration thickness parameter on the design drawing to determine whether there is a deviation. If there is a deviation, the position of the laser transmitter is manually adjusted again, the elevation control line is re-popped up, and re-checked until the data matches, and the elevation data and position information are recorded as the line positioning result, which may include:

[0081] Step 1255, compare the actual elevation of the structural plate with the decoration thickness parameter on the design drawing, and calculate the deviation value ΔH = (H + H a )-(T+T t +T c ), where ΔH represents the difference between the actual elevation and the design drawing; H represents the actual elevation; H a Indicates the elevation adjustment coefficient; T indicates the decoration thickness on the design drawing; T t Indicates the allowable deviation of the decoration thickness; T c represents the weight parameter;

[0082] Step 1256, if there is a deviation, that is, ΔH≠0, manually adjust the position of the laser transmitter again according to the deviation value, re-pop up the elevation control line, and perform another calibration;

[0083] Step 1257, repeat the process of comparison, adjustment, and verification until the deviation value ΔH approaches zero, that is, ΔH≈0, and record the elevation data and position information as the result of line positioning.

[0084] In the embodiment of the present invention, a measuring tool (such as a level, a tape measure, etc.) is used to measure the actual elevation of the structural plate, which is recorded as H. According to the design drawings, the decoration thickness parameter T and the decoration thickness allowable deviation T are obtained. t and weight parameter T c . Calculate the deviation value ΔH. Where, H a It is the elevation adjustment coefficient, which may be adjusted according to the construction situation or specific requirements. If ΔH=0, it means that there is a deviation between the actual elevation and the design drawing. According to the size and direction of the deviation value ΔH, manually adjust the position of the laser transmitter. If ΔH is positive, it means that the actual elevation is too high and the laser transmitter needs to be adjusted downward; conversely, if ΔH is negative, it means that the actual elevation is too low and the laser transmitter needs to be adjusted upward. After adjusting the position of the laser transmitter, restart the laser transmitter and a new elevation control line will pop up along the edge of the wall. Use a wire pulling tool or other measuring tools to recheck the elevation of the structural plate along the new elevation control line. Make sure that the new elevation control line matches the actual elevation of the structural plate, that is, the deviation value is close to zero. When the deviation value ΔH≈0, record the elevation data, position information and adjustment parameters of the laser transmitter at this time. This information will be used as the result of line positioning.

[0085] Through the cycle of continuous comparison, adjustment, and verification, the actual elevation of the structural plate can be ensured to be highly consistent with the requirements on the design drawings, thereby improving the accuracy of the layout and positioning. This helps to accurately install the overhead modules and other construction steps. The calculation and adjustment process of the deviation value ΔH can timely discover and correct errors in construction and avoid construction quality problems caused by error accumulation. This helps to improve the overall construction quality and the aesthetics of the project. a , Decoration thickness allowable deviation T t and weight parameter T c With parameters such as the actual height and position of the equipment, construction personnel can more flexibly respond to various situations in actual construction and enhance the controllability of construction. The final elevation data and location information are recorded as the result of line setting and positioning. Accurate line setting and positioning can ensure the flatness and stability of the overhead ground system and improve the user experience. At the same time, it can reduce problems such as uneven ground and abnormal noise caused by construction errors, thereby improving user satisfaction.

[0086] In a preferred embodiment of the present invention, the above step 13, according to the result of the line positioning, the overhead board is installed according to the overhead board layout diagram, and during the installation process, the spacing of the anchor bolts does not exceed 400mm to obtain the preliminary installed overhead module, which may include:

[0087] Step 131, receiving and reviewing the results of the line setting and positioning, including elevation data and location information;

[0088] Step 132, according to the overhead panel layout drawing, prepare overhead panels of corresponding specifications and quantity, as well as installation tools, including anchor bolts, wrenches, and screwdrivers, and mark the starting point of the overhead panel installation on the wall;

[0089] Step 133, starting from the starting point, placing the overhead panels one by one at the predetermined positions according to the overhead panel layout diagram, and when placing the overhead panels, ensuring that the overhead panels are parallel to the wall and the edges are aligned with the elevation control line;

[0090] Step 134, at the four corners of the overhead plate, use anchor bolts to fix the overhead plate to the ground, so that the spacing between the anchor bolts does not exceed 400 mm, to obtain a preliminarily installed overhead module.

[0091] In an embodiment of the present invention, the results of the positioning of the wire laying out are received and reviewed, including elevation data and location information. According to the overhead panel layout drawing, the results of the positioning of the wire laying out are received and reviewed, including elevation data and location information. This is the basis for the installation of the overhead panel. According to the overhead panel layout drawing, overhead panels of corresponding specifications and quantities, as well as the required installation tools, are prepared. At the same time, installation tools such as anchor bolts, wrenches, and screwdrivers are also prepared. The starting point of the overhead panel installation is marked on the wall. Calculate the diagonal length of the overhead panel Where l is the length of the overhead board and w is the width of the overhead board. Starting from the starting point, place the overhead boards one by one at the predetermined positions according to the overhead board layout diagram. The position of each overhead board is calculated based on its length and the number of overhead boards already placed, ensuring that the overhead board is parallel to the wall and the edge is aligned with the elevation control line. The specific placement positions are as follows:

[0092] The first overhead plate: position (0, 0).

[0093] The second overhead plate: position (400, 0). ...

[0095] The 10th overhead plate: position (3600, 0).

[0096] At the four corners of the overhead board, use anchor bolts to fix the overhead board to the ground. Since the diagonal length has been verified to meet the requirements, it can be ensured that the spacing between the anchor bolts does not exceed 400mm, and the installation of the overhead board is completed.

[0097] The accuracy of the overhead panel installation was ensured by receiving and reviewing the results of the layout and positioning, including elevation data and location information. This helps to avoid errors during the installation process and improve the overall installation quality. The overhead panels and installation tools of corresponding specifications and quantities are prepared according to the overhead panel layout drawing, making the installation process more orderly and efficient. Planning in advance and preparing sufficient materials can reduce interruptions and delays during the installation process. The starting point of the overhead panel installation is marked on the wall, and the overhead panels are placed one by one according to the layout drawing from the starting point, ensuring that the position and direction of each overhead panel are consistent. This helps to maintain the beauty and stability of the overall installation. The overhead panels are fixed to the ground with anchor bolts at the four corners, and the spacing between the anchor bolts does not exceed 400mm, which enhances the firmness and stability of the overhead panels. This installation method can effectively prevent the overhead panels from moving or tilting during use, ensuring their long-term stable operation. The clear structure and standardized installation of the initially installed overhead modules provide convenience for subsequent inspection, maintenance and replacement. The orderly installation method makes it easier for maintenance personnel to identify problems and deal with them in a timely and effective manner. Strictly following the installation process to install the overhead panel ensures the safety and reliability of the entire overhead module. Firm installation and precise positioning help prevent accidents and provide a safer working environment for users and maintenance personnel.

[0098] In a preferred embodiment of the present invention, the above step 14, based on the preliminarily installed overhead module, uses a leveling tool to level the overhead plate, and injects glue to fix the anchor bolts; at the same time, checks and repairs the bumps of the aluminum foil reflective film to obtain an adjusted and fixed overhead module, which may include:

[0099] Step 144, receiving and checking the preliminarily installed overhead modules, and confirming that the overhead panels have been installed according to the laying-out positioning results and the overhead panel layout drawing;

[0100] Step 145, preparing leveling tools, including a level ruler, an adjustment gasket, and an injection material for fixing the anchor bolts, including epoxy resin glue;

[0101] Step 146, using a level ruler to check the levelness of each overhead plate, for uneven places, leveling by inserting adjustment shims under the anchor bolts or adjusting the height of the anchor bolts, and injecting glue into each anchor bolt;

[0102] Step 147, use a glue injection gun to inject epoxy resin glue into the holes of the anchor bolts, and check whether the aluminum foil reflective film on the surface of the overhead board is bumped, damaged or missing. If the aluminum foil reflective film is bumped, damaged or missing, use aluminum foil tape to repair the reflective film to obtain an adjusted and fixed overhead module.

[0103] In an embodiment of the present invention, the results of the laying out and positioning and the layout of the overhead panels transmitted from the previous process are received. The overhead modules that have been preliminarily installed are checked one by one against the results of the laying out and positioning and the layout of the overhead panels. Confirm that the position, direction and relative relationship of each overhead panel with other panels meet the design requirements. Prepare a level ruler, adjustment shims and necessary measuring tools. The level ruler is used to detect the levelness of the overhead panel, and the adjustment shims are used to fine-tune unevenness. Epoxy resin glue is selected as the fixing material for the anchor bolts. Epoxy resin glue has good bonding strength and durability, and can ensure that the anchor bolts are firmly fixed. Place the level ruler on the surface of the overhead panel and check the levelness of each panel one by one. For any unevenness found, record its position and height difference. For minor unevenness, it can be corrected by inserting an adjustment shim of appropriate thickness under the anchor bolt. For situations where a larger adjustment is required, consider adjusting the height of the anchor bolt.

[0104] Assuming that a certain overhead board is 2mm lower than the ideal horizontal plane at point A, a 2mm thick adjustment shim can be placed under the anchor bolt at this point to achieve the purpose of leveling. Use a glue injection gun to evenly inject epoxy resin glue into the holes of the anchor bolts. When injecting glue, make sure that the glue fills the entire hole and overflows a little from the hole to form a complete glue layer. After injecting glue, wait for the glue to solidify to ensure that the anchor bolts are firmly fixed. Carefully check the aluminum foil reflective film on the surface of the overhead board to see if there are any bumps, damage or missing. For any problems found, immediately use aluminum foil tape reflective film to repair. When repairing, make sure that the tape fits tightly with the original reflective film without bubbles and wrinkles to maintain the reflective effect. Perform a comprehensive inspection of the adjusted and fixed overhead modules to confirm that all overhead boards are in a horizontal state, the anchor bolts are firmly fixed, and the aluminum foil reflective film is intact. Fill in the acceptance record form to record in detail the various data, adjustment measures and final inspection results during the installation process. Ensure that all work meets the design requirements and quality standards.

[0105] The levelness of each overhead board is accurately checked by using a level ruler, and uneven areas are adjusted in time to ensure the flatness and stability of the overhead board installation. This helps to reduce stress concentration and potential structural problems caused by uneven installation. Each anchor bolt is injected with glue, and the bolt holes are filled with epoxy resin glue, which effectively enhances the bonding force between the anchor bolt and the ground. This not only prevents the bolts from loosening, but also improves the structural strength and durability of the entire overhead module. The aluminum foil reflective film on the surface of the overhead board is checked and repaired to ensure the integrity and continuity of the reflective film. This helps to maintain the heat reflection performance of the reflective film, improve the thermal insulation effect of the overhead module, and reduce energy consumption. After adjustment, fixation and repair, the overhead module is not only structurally stable and functional, but also neat and beautiful in appearance. This helps to enhance the overall image of the entire building or facility, while extending the service life of the overhead module. Accurate installation and firm fixation reduce the need for subsequent maintenance. At the same time, the complete aluminum foil reflective film also reduces the frequency of repairs due to damage or missing, thereby simplifying the overall maintenance and management process. The safety and reliability of the overhead modules are ensured through strict leveling, fixing and repairing procedures. This helps prevent safety accidents caused by improper installation or material damage, and provides a safer working environment for users and maintenance personnel.

[0106] In a preferred embodiment of the present invention, the above step 15, according to the adjusted and fixed overhead module, lays the floor heating pipe in the installed overhead groove so that the floor heating pipe fits tightly with the groove to obtain the floor heating pipe system, which may include:

[0107] Step 151, receiving the adjusted and fixed overhead module, and preparing a sufficient number of floor heating pipes according to the construction drawings and floor heating pipe specifications, and preparing tools for laying floor heating pipes, including scissors, pipe clamps, and pipe bender;

[0108] Step 152, according to the design drawing, determine the laying starting point of the floor heating pipe in the overhead layer groove and mark the positioning line;

[0109] Step 153, starting from the starting point, place the floor heating pipe section by section into the overhead layer groove, so that the floor heating pipe fits tightly with the groove. During the laying process, keep the floor heating pipe straight to ensure smooth water flow and normal operation of the floor heating system;

[0110] Step 154, use pipe clamps or straps to fix the floor heating pipes in the grooves of the overhead layer to prevent movement or displacement during use, and inspect the floor heating pipes to ensure that the floor heating pipes are laid flat and fit tightly in the grooves without any looseness, hanging or twisting, thereby obtaining a floor heating pipe system.

[0111] In an embodiment of the present invention, an adjusted and firmly fixed overhead module is received to ensure that the installation quality of the module meets the design requirements. According to the construction drawings and floor heating pipe specifications, the number of required floor heating pipes is accurately calculated, and sufficient pipes are prepared. At the same time, tools required for laying floor heating pipes are prepared, such as scissors (for cutting floor heating pipes), pipe clamps or straps (for fixing floor heating pipes), pipe benders (for bending floor heating pipes when necessary), etc. Carefully read the design drawings for laying floor heating pipes to clarify the route, starting point and end point of the laying. Use a pen or marker pen to clearly mark the positioning line in the groove. This helps to ensure accuracy and consistency during the laying process. Starting from the marked starting point, place the floor heating pipe section by section into the overhead layer groove. During the placement process, special attention should be paid to ensure that the floor heating pipe fits tightly with the groove to avoid gaps or looseness. During the laying process, the floor heating pipe should always be kept straight. The pipe can be gently adjusted by hand or tools to ensure that it extends smoothly along the designed route. This helps to ensure smooth water flow and the normal operation of the floor heating system.

[0112] Suppose that when laying a section of floor heating pipe, it is found that the pipe is difficult to keep straight due to the irregular shape of the groove. At this time, a pipe bender can be used to slightly bend the pipe to make it better fit the shape of the groove while maintaining smooth water flow. Use pipe clamps or bands to fix the floor heating pipe in the overhead groove. The fixing point should be selected at the bend of the pipe or a position that is susceptible to external forces to ensure that the pipe will not move or shift during use. After laying, conduct a comprehensive inspection of the floor heating pipe system. The inspection content includes whether the floor heating pipe is laid flat, fits tightly in the groove, and is not loose, hanging or twisted; whether the pipe clamps or bands are firmly fixed; and whether the entire system meets the requirements of the design drawings. If any problems are found during the inspection, such as loose, hanging or twisted pipes, they should be repaired immediately. Additional pipe clamps or bands can be used for reinforcement, or the position of the pipe can be adjusted to ensure that it fits tightly in the groove. Fill out the acceptance record form to record the various data, adjustment measures and final inspection results during the laying process in detail. Only after ensuring that all work meets the design requirements and quality standards can the next step of construction or installation be carried out.

[0113] The floor heating pipe fits tightly in the overhead groove, reducing the loss during heat transfer and improving the thermal efficiency of the floor heating system. Keeping the floor heating pipe straight during the laying process effectively avoids the increase in water flow resistance caused by pipe bending or twisting. This ensures smooth water flow in the floor heating system, improves the operating efficiency of the system, and reduces the risk of failure due to poor water flow. Use pipe clamps or straps to fix the floor heating pipe in the overhead groove to prevent the movement or displacement of the floor heating pipe during use. This enhances the stability of the floor heating system and reduces the risk of noise, wear or damage caused by pipe movement. The floor heating pipe fits tightly in the groove and is firmly fixed, reducing the possibility of damage to the pipe due to vibration, friction or external force. This helps to extend the service life of the floor heating pipe and reduce the cost of maintenance and replacement of pipes.

[0114] The floor heating pipes are laid strictly according to the design drawings, and professional tools are used for cutting, fixing and checking to ensure the flatness and accuracy of the laying. This not only improves the construction quality, but also makes the floor heating system more beautiful and tidy. The floor heating pipe system has a clear structure and is firmly fixed, which is convenient for subsequent maintenance and management. If the floor heating system needs to be repaired or cleaned, it is easier to find and deal with the problem points, reducing the difficulty and cost of maintenance.

[0115] In a preferred embodiment of the present invention, the above step 16, according to the floor heating pipe system, performs a pressure test on the indoor floor heating system to ensure that the floor heating system has no leakage and the pressure is stable, and performs the plate surface construction on the overhead layer to complete the final structure of the building overhead floor, including:

[0116] Step 161, according to the pressure test standard of the floor heating system, prepare the pressure test equipment, including the pressure pump and the pressure gauge;

[0117] Step 162, connect the pressure pump to the water inlet of the floor heating system, close the exhaust valve and the drain valve, start pressure pumping, and gradually increase the system pressure until the preset test pressure is reached;

[0118] Step 163, during the pressure test, observe the reading of the pressure gauge and check whether there are any leaks at the joints, valves, and connectors of the floor heating pipe system. If there are any leaks, stop the pressure test immediately, mark the leaking location, and perform repairs;

[0119] Step 164, after the repair is completed, re-perform the pressure test until the system has no leakage and the pressure is stable, and start preparing materials for the panel surface construction, including floor tiles, wooden floors, carpets and corresponding auxiliary materials, including adhesives and caulking agents;

[0120] Step 165, construct the panel surface layer on the elevated layer of the floor heating system, and lay the panel materials one by one on the elevated layer according to a certain laying order and pattern. During the laying process, make the gaps between the panels uniform, and use adhesives or caulking agents to fix and fill the gaps to complete the final structure of the elevated floor of the building.

[0121] In an embodiment of the present invention, according to the pressure test standard of the floor heating system, the required pressure test equipment is prepared, including a pressure pump, a pressure gauge, and connecting pipes. Ensure that all equipment is in good working condition and the accuracy of the pressure gauge meets the test requirements. Connect the pressure pump to the water inlet of the floor heating system through the connecting pipe to ensure that the connection is tight and leak-free. Close all exhaust valves and drain valves of the floor heating system to form a closed test environment. Start the pressure pump and gradually increase the system pressure until the preset test pressure value is reached. Usually, the test pressure of the floor heating system will be higher than the normal working pressure to ensure the reliability of the system. During the pressure test, closely observe the reading of the pressure gauge to ensure that the pressure rises steadily. During the pressure test, carefully check the various connections, valves, joint positions, etc. of the floor heating pipe system to observe whether there is any leakage. If a leak is found, stop the pressure test immediately and mark the leak location. Use appropriate tools and methods to repair the leak point, such as replacing the gasket, tightening the connector, etc. After the repair is completed, re-perform the pressure test until the system is leak-free and the pressure is stably maintained near the preset test pressure value. After confirming that there are no leaks in the system, turn off the pressure pump and disconnect it from the floor heating system.

[0122] Suppose that during the pressure test of the floor heating system, a slight leak is found at a joint. At this time, the pressure test should be stopped immediately and the leak location should be marked with a marker. Then, the pressure test equipment should be turned off, the connector of the joint should be tightened with a wrench or screwdriver, and a new gasket should be replaced. After the repair is completed, the pressure test should be performed again to confirm that the leak has been eliminated and the system pressure is stable. According to the design requirements, prepare the required panel surface construction materials, such as floor tiles, wooden floors, carpets, etc., and the corresponding auxiliary materials, such as adhesives, caulking agents, etc. Ensure that all materials meet the quality standards and are sufficient in quantity to meet the construction needs. Clean the surface of the overhead layer to ensure that there are no debris, dust, and other factors that affect the construction quality. According to the design drawings, determine the laying order and pattern of the panel surface layer. According to the predetermined laying order and pattern, lay the panel materials one by one on the overhead layer. During the laying process, use tools such as a level ruler or a pull line to ensure that the gaps between the panels are uniform. Depending on the type of material, use adhesives or caulking agents to fix and caulk the panels. For floor tiles, cement mortar may be used for laying; for wooden floors, special wooden floor glue may be used for fixing; for carpets, carpet glue or carpet nails may be used for fixing. After laying, conduct a comprehensive inspection of the surface of the tiles to ensure that they are laid flat, the gaps are even, and there is no looseness or warping. Check whether the caulking agent or adhesive is completely cured and there are no cracks or peeling.

[0123] Suppose you want to lay wooden flooring on the overhead floor. First, clean the surface of the overhead floor to ensure it is clean and dust-free. Then, determine the direction and pattern of laying the wooden flooring according to the design drawings. Next, use wooden flooring glue to lay the wooden floorings one by one on the overhead floor, and use a level ruler to ensure that the gaps between each flooring are even. During the laying process, for the floors that need to be cut, use a saw or a cutter to make precise cuts. Finally, use caulking agent to fill the gaps in the flooring and wait for it to cure completely. After the construction is completed, conduct a comprehensive inspection of the wooden flooring. After confirming that there are no quality problems, you can place furniture or use it.

[0124] Through the pressure test, the leakage points in the floor heating system can be found in time and repaired. This ensures that the floor heating system will not cause pressure drop or water loss due to leakage during use, thereby ensuring the stability and safety of the system. The pressure test can verify whether the floor heating system can withstand the preset test pressure, and then infer its reliability under normal working pressure. The positions of various joints, valves, joints, etc. of the floor heating system that has been pressure tested have been checked and confirmed, reducing the safety hazards caused by system leakage. By constructing the plate surface layer on the overhead floor, the pipes and components of the floor heating system can be covered, making the indoor floor more tidy and beautiful. Whether it is floor tiles, wooden floors or carpets, they can add warmth and comfort to the indoor space. The plate surface layer construction can enhance the stability of the overhead floor. Through a reasonable laying order and pattern, and the use of adhesives or caulking agents for fixing and caulking, the connection between the plates can be ensured to be tight and firm, thereby avoiding problems such as loosening or collapse of the ground. The selected plate materials (such as floor tiles, wooden floors, etc.) usually have high durability and wear resistance. This can extend the service life of the elevated floor and reduce the cost of repair and replacement due to floor damage. Floors constructed with slab surface are usually easier to clean and maintain. Whether it is daily cleaning or professional maintenance, it can be easily handled. This reduces the difficulty and cost of cleaning and maintenance and improves the user experience. Beautiful, stable and durable elevated floor can enhance the overall value of the building.

[0125] like Figure 3 As shown, in another preferred embodiment of the present invention, the overhead plate is provided with a plurality of overhead supports fixed on the ground to achieve separation of the pipeline and the structural plate;

[0126] A pressed membrane shell is installed on the overhead board, and a groove is designed on the surface of the pressed membrane shell for laying and fixing the floor heating pipes and evenly dissipating the heat to the ground to achieve the floor heating function. At the same time, it serves as a protective layer to prevent the external environment from causing damage to the floor heating pipes and the underlying structure.

[0127] In an embodiment of the present invention, the overhead supports are fixed to the ground, and they serve as support points to lift the overhead board to form a certain space. This space is used to accommodate other pipelines such as floor heating pipes and electric wires to separate the pipelines from the structural board. The overhead board serves as a bearing platform for these pipelines to ensure that they can be laid stably and safely. On the overhead board, a layer of pressed film shell is installed. The surface of the pressed film shell is designed with grooves, and the shape and size of these grooves match the floor heating pipes, which are used to lay and fix the floor heating pipes. The floor heating pipes are embedded in the grooves, and are ensured to be stable and motionless in the grooves by specific fixing methods (such as snaps, glue, etc.). When the floor heating system is working, the heat generated by the hot water or electric heating element is transferred to the pressed film shell through the floor heating pipe, and then the pressed film shell evenly dissipates the heat to the ground. In this way, the entire ground can become a uniform heat source to realize the floor heating function. The pressed film shell not only serves as a carrier for the floor heating pipe, but also acts as a protective layer. It can effectively prevent the external environment (such as moisture, dust, mechanical damage, etc.) from causing damage to the floor heating pipes and the underlying structure, thereby extending the service life of the floor heating system.

[0128] Through the design of overhead supports and overhead plates, the separation of pipelines and structural plates is achieved, reducing heat loss during heat transfer. At the same time, the groove design of the pressed membrane shell ensures the stable laying of the floor heating pipes and the uniform heat dissipation, improving the overall efficiency of the floor heating system. The overhead supports provide stable support for the overhead plates, preventing structural deformation caused by the weight of the pipelines or external pressure. The pressed membrane shell fixes the floor heating pipes to prevent them from moving or displacing during operation, thereby enhancing the stability of the system. As a protective layer, the pressed membrane shell effectively isolates the floor heating pipes from the external environment and reduces the risk of pipeline aging, corrosion or damage caused by environmental factors. This helps to extend the service life of the floor heating system and reduce maintenance and replacement costs. The design of the overhead supports and overhead plates makes pipeline laying more flexible and convenient. Construction personnel can adjust the height and position of the overhead plates according to actual needs to meet the laying requirements of different pipelines. At the same time, the groove design of the pressed membrane shell also facilitates the rapid laying and fixing of floor heating pipes.

[0129] like Figure 3 As shown, in another preferred embodiment of the present invention, floor heating pipes are laid in the grooves of the pressed membrane shell, and heat is transferred to the ground through circulating hot water or hot air to increase the indoor temperature, thereby ensuring uniform distribution of the indoor temperature.

[0130] In an embodiment of the present invention, the groove design of the pressed membrane shell is to efficiently lay and fix the floor heating pipe. The floor heating pipe is embedded in these grooves, and it is ensured to be stable and immovable in the groove by a specific method (such as snaps, adhesives or special fixings). When the floor heating system is started, the circulating hot water or hot air flows through the floor heating pipe, carrying a large amount of heat energy. This heat energy is transferred to the pressed membrane shell through the floor heating pipe wall, and then the pressed membrane shell evenly dissipates the heat to the entire ground. The material of the pressed membrane shell has good thermal conductivity and can quickly conduct the heat in the floor heating pipe to the ground. At the same time, the groove design on its surface also increases the contact area with the floor heating pipe, further improving the efficiency of heat transfer. As the ground heats up, the temperature of the entire indoor space gradually rises, achieving a uniform distribution of indoor temperature. The groove design of the pressed membrane shell increases the contact area with the floor heating pipe, so that heat can be more efficiently transferred from the floor heating pipe to the ground. This improves the heat transfer efficiency of the floor heating system and shortens the time for the indoor temperature to rise. As a heat transfer medium, the pressed membrane shell can ensure that the heat is evenly dissipated to the entire ground. This avoids local overheating or uneven temperatures and provides a more comfortable indoor environment.

[0131] The pressed membrane shell not only serves as a heat transfer medium, but also plays a role in protecting the floor heating pipe. It can effectively prevent the external environment (such as trampling, impact, moisture, etc.) from damaging the floor heating pipe and extend the service life of the floor heating system. The groove design of the pressed membrane shell makes the laying of the floor heating pipe easier and faster. The construction workers only need to embed the floor heating pipe into the groove and simply fix it. This improves construction efficiency and shortens the construction period. Due to the efficient heat transfer and uniform heat dissipation characteristics of the pressed membrane shell, the floor heating system can achieve the same indoor temperature with lower energy consumption. This helps save energy and reduce operating costs.

[0132] like Figure 3 As shown, in another preferred embodiment of the present invention, an aluminum foil reflective film is laid above the pressed membrane shell and between the composite bricks to enhance the thermal insulation and heat insulation performance of the ground;

[0133] Composite bricks are laid on top of the aluminum foil reflective film. The composite bricks serve as the final laying layer of the overhead floor system and are in direct contact with users.

[0134] In an embodiment of the present invention, laying an aluminum foil reflective film above the pressed membrane shell and between the composite bricks is an important part of the floor heating overhead ground system. The aluminum foil reflective film has excellent reflective properties, which can reflect most of the heat and reduce the downward loss of heat, thereby enhancing the thermal insulation performance of the ground. At the same time, the aluminum foil reflective film can also play a certain role in heat insulation, preventing the influence of external cold air on the floor heating system and improving the overall efficiency of the floor heating system. Laying composite bricks above the aluminum foil reflective film completes the final laying layer of the overhead ground system. As the layer that directly contacts the user, the composite bricks are not only beautiful and durable, but also can effectively and evenly dissipate the heat transferred from the floor heating system to the indoor space, thereby achieving uniform distribution of indoor temperature.

[0135] Specifically, when the floor heating system is working, the circulating hot water or hot air flows through the floor heating pipes, transferring heat to the pressed membrane shell. The pressed membrane shell then transfers the heat to the aluminum foil reflective membrane, which reflects most of the heat and dissipates it upwards. At the same time, part of the heat is also transferred to the composite bricks through heat conduction. After absorbing this heat, the composite bricks evenly dissipate it into the indoor space, thereby increasing the indoor temperature.

[0136] The laying of aluminum foil reflective film can effectively reflect heat and reduce the downward loss of heat, thereby enhancing the thermal insulation performance of the floor. This helps to reduce the energy consumption of the floor heating system and improve energy efficiency. The aluminum foil reflective film can also play a certain role in heat insulation, preventing the influence of cold air from the outside on the floor heating system. This helps to maintain the stability of indoor temperature and improve the overall efficiency of the floor heating system. As the final laying layer of the overhead floor system, the composite brick can effectively and evenly dissipate the heat transferred from the floor heating system to the indoor space. This avoids local overheating or uneven temperature and provides a more comfortable indoor environment. The laying of aluminum foil reflective film and composite bricks provides an extra layer of protection for the floor heating system. They can prevent the external environment (such as moisture, dust, mechanical damage, etc.) from damaging the floor heating pipes and extend the service life of the floor heating system.

[0137] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
