Description
Technical Field
[0001] This invention relates to the field of roof insulation technology, and in particular to a building roof insulation system and its construction method. Background Technology
[0002] With increasingly stringent requirements for building energy conservation, roof insulation technology has become an important component of building energy efficiency. Currently, significant progress has been made both domestically and internationally in roof insulation technology, primarily through methods such as the application of traditional insulation materials, the use of reflective thermal insulation coatings, and the design of ventilated insulation layers.
[0003] Existing thermal insulation materials are susceptible to environmental factors that cause performance degradation. Reflective thermal insulation coatings show a significant decrease in reflectivity after long-term exposure, resulting in poor roof thermal insulation performance. Summary of the Invention
[0004] To address the problem of poor roof insulation performance caused by the significant decline in reflectivity of reflective thermal insulation coatings after long-term exposure, this application provides a building roof insulation system and its construction method.
[0005] In the first aspect, the technical solution of the building roof thermal insulation system and its construction method provided in this application is as follows: A building roof thermal insulation system includes multiple extruded polystyrene boards laid on the roof, the surface of the extruded polystyrene boards being covered with an aluminum foil reflective film, the surface of the aluminum foil reflective film being coated with polymer cement mortar, and a fixing component for fixing the extruded polystyrene boards to the roof.
[0006] By adopting the above technical solution, the extruded polystyrene board is fixed to the roof through fixing components. The insulation layer reduces heat transfer through the low thermal conductivity of the extruded polystyrene board, the heat insulation layer reflects solar radiation through aluminum foil reflective film to reduce heat absorption, and the protective layer prevents the external environment from damaging the insulation layer and the heat insulation layer, while enhancing the overall durability, thereby improving the roof's thermal insulation effect.
[0007] Preferably, the seams of the aluminum foil reflective film are overlapped, and the seams of the aluminum foil reflective film are fixedly connected by an adhesive.
[0008] By adopting the above technical solution, the edges of two adjacent aluminum foil reflective films are overlapped when laying the aluminum foil reflective film, thereby improving the laying quality of the aluminum foil reflective film.
[0009] Preferably, the fixing component includes a base plate, which is fixed to the roof by bolts. A support plate is fixed to the top surface of the base plate. A sliding groove is provided on the top surface of the support plate. A movable plate is slidably arranged in the sliding groove along the vertical direction. Two pressure plates are symmetrically arranged at the top of the movable plate. The bottom surface of the pressure plate abuts against the top surface of the extruded polystyrene board.
[0010] By adopting the above technical solution, the base plate is fixed to the roof with bolts, then the moving plate is moved upward, which drives the pressure plate to move upward, and then the extruded polystyrene board is placed on the base plate. Then the moving plate is moved downward, so that the pressure plate presses on the top surface of the extruded polystyrene board, thereby fixing the extruded polystyrene board to the roof.
[0011] Preferably, a plurality of springs are fixed to the bottom surface of the movable plate, and the bottom end of each spring is fixed to the inner bottom surface of the sliding groove.
[0012] By adopting the above technical solution, when the end of the extruded polystyrene board is placed between the base plate and the pressure plate, the moving plate moves downward under the elastic force of the spring, thereby pressing the pressure plate against the top surface of the extruded polystyrene board.
[0013] Preferably, mounting plates are fixed to both ends of the top surface of the movable plate, and rotating shafts are fixed to both ends of the pressure plate. The rotating shafts are rotatably mounted on the side of the mounting plate, and the mounting plate is provided with fasteners for fixing the pressure plate.
[0014] By adopting the above technical solution, when the base plate is fixed to the roof with bolts, the pressure plate is rotated to a vertical position, which makes it easier to place the extruded polystyrene board on the base plate. Then the pressure plate is rotated toward the extruded polystyrene board so that the pressure plate presses on the top surface of the extruded polystyrene board. The pressure plate is fixed by fasteners, reducing the rotation of the pressure plate, thereby fixing the extruded polystyrene board to the roof.
[0015] Preferably, each of the two mounting plates has a mounting groove at both ends of its opposite sides. A fixing block is slidably disposed in the mounting groove. The bottom surface of the fixing block abuts against the top surface of the pressure plate. A second spring is fixed to the end face of the fixing block away from the pressure plate. The end of the second spring away from the fixing block is fixed to the inner wall of the mounting groove.
[0016] By adopting the above technical solution, the pressure plate is rotated toward the extruded polystyrene board, so that the pressure plate presses on the top surface of the extruded polystyrene board. The fixing block moves under the elastic force of the second spring, so that the bottom surface of the fixing block abuts against the top surface of the extruded polystyrene board, thereby fixing the extruded polystyrene board between the pressure plate and the bottom plate.
[0017] Preferably, the inner wall of the mounting groove has a through hole, and a pull rod is fixed to the end face of the fixing block away from the pressure plate, with the end of the pull rod away from the fixing block passing through the through hole.
[0018] By adopting the above technical solution, the pull rod is pulled away from the pressure plate, causing the pull rod to move the fixing block and move the fixing block into the mounting groove, thereby facilitating the rotation of the pressure plate.
[0019] Preferably, the end face of the fixing block away from the second spring has an inclined surface.
[0020] By adopting the above technical solution, an inclined surface is opened on the end face of the fixed block away from the second spring. When the pressure plate rotates downward, the pressure plate drives the inclined surface to move, so that the inclined surface drives the fixed block to move into the mounting groove. When the pressure plate is separated from the fixed block, the fixed block moves under the elastic force of the second spring, so that the fixed block moves above the pressure plate. The bottom surface of the fixed block abuts against the top surface of the pressure plate, thereby restricting the movement of the pressure plate.
[0021] Secondly, the construction method for thermal insulation of building roofs provided in this application adopts the following technical solution: A method for constructing thermal insulation on building roofs includes the following steps: S1: Clean the roof surface base to ensure it is flat and free of debris; S2: Lay extruded polystyrene boards and fix them to the roof using fixing components; S3: Cover the surface of the extruded polystyrene board with an aluminum foil reflective film and fix it with an adhesive; S4: Coat the surface of the aluminum foil reflective film with a polymer cement mortar protective layer and trowel it evenly; S5: Curing and protective layer to ensure complete curing.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The extruded polystyrene board is fixed to the roof by fixing components. The insulation layer reduces heat transfer through the low thermal conductivity of the extruded polystyrene board. The heat insulation layer reflects solar radiation through aluminum foil reflective film, reducing heat absorption. The protective layer prevents the external environment from damaging the insulation layer and the heat insulation layer, while enhancing the overall durability, thereby improving the roof's thermal insulation effect. 2. Fix the base plate to the roof with bolts, then move the moving plate upwards. The moving plate will drive the pressure plate upwards. Then place the extruded polystyrene board on the base plate. Then move the moving plate downwards so that the pressure plate presses on the top surface of the extruded polystyrene board, thereby fixing the extruded polystyrene board to the roof. 3. When the base plate is fixed to the roof with bolts, rotate the pressure plate to a vertical position, so that the extruded polystyrene board can be placed on the base plate. Then rotate the pressure plate toward the extruded polystyrene board so that the pressure plate presses on the top surface of the extruded polystyrene board. Fix the pressure plate with fasteners to reduce the rotation of the pressure plate, thereby fixing the extruded polystyrene board to the roof. Attached Figure Description

An aluminum foil reflective film 11 is laid on the surface of each extruded polystyrene board 1, with the seams of the aluminum foil reflective film 11 overlapping by 100mm and fixed together by an adhesive. The surface of the aluminum foil reflective film 11 is coated with polymer cement mortar 12.
[0032] Reference Figure 2 , Figure 3 and Figure 4A fixing assembly 2 is provided between two horizontally adjacent extruded polystyrene boards 1. The fixing assembly 2 includes a base plate 21, which is fixed to the roof with bolts. A support plate 22 is fixed to the top surface of the base plate 21. A sliding groove 23 is formed on the top surface of the support plate 22. A movable plate 24 is slidably arranged vertically in the sliding groove 23. A plurality of springs 26 are fixed to the bottom surface of the movable plate 24. The plurality of springs 26 are evenly spaced along the length of the movable plate 24, and the bottom end of the springs 26 is fixed to the inner bottom surface of the sliding groove 23. Two pressure plates 25 are symmetrically arranged at the top of the movable plate 24. The bottom surface of the pressure plates 25 abuts against the top surface of the extruded polystyrene board 1.
[0033] Reference Figure 4 and Figure 5 Mounting plates 3 are fixed to both ends of the top surface of the movable plate 24, and rotating shafts 31 are fixed to both ends of the pressure plate 25. The rotating shafts 31 are rotatably connected to the mounting plates 3. Mounting grooves 32 are provided at both ends of the opposite sides of the two mounting plates 3. Fixing blocks 33 are slidably arranged in the mounting grooves 32. A second spring 34 is fixed to the end face of the fixing block 33 away from the pressure plate 25. The end of the second spring 34 away from the fixing block 33 is fixed to the inner wall of the mounting groove 32. An inclined surface 35 is provided on the end face of the fixing block 33 away from the second spring 34.

[0034] The implementation principle of a building roof thermal insulation system according to an embodiment of this application is as follows: the base plate 21 is fixed to the roof with bolts, the pressure plate 25 is rotated to a horizontal state, the pressure plate 25 presses the inclined surface 35 when rotating, causing the inclined surface 35 to move into the mounting groove 32, the inclined surface 35 drives the fixing block 33 to move into the mounting groove 32, when the inclined surface 35 disengages from the pressure plate 25, the fixing block 33 moves out of the mounting groove 32 under the elastic force of the spring 26, so that the bottom surface of the fixing block 33 abuts against the top surface of the extruded polystyrene board 1, thereby restricting the rotation of the pressure plate 25. Then, the movable plate 24 is pulled upwards, and the spring 26 is in a stretched state. The extruded polystyrene board 1 is then placed on the base plate 21.

Then, the aluminum foil reflective film 11 is laid on the top surface of the extruded polystyrene board 1, with two adjacent aluminum foil reflective films 11 overlapping by 100mm and fixed together with adhesive. Finally, polymer cement mortar 12 is laid on the surface of the aluminum foil reflective film 11.
