The sun protection and waterproofing problems on their roofs are prominent. In the renovation process, it is inevitable to carry out waterproofing, thermal insulation and other treatments on their roofs. In the actual construction process, traditional waterproofing and thermal insulation only use asphalt, waterproof cloth, silver-plated cloth, polypropylene cloth, etc. directly laid on the top of the old building, and covered with isostructural glue or asphalt to achieve thermal insulation effect.

[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principles of the existing building roof waterproofing and cooling structures are first introduced.

[0028] During the renovation of existing old residential communities, the rooftops of buildings are waterproofed by covering them with waterproof membranes or building colored steel tile roofs, and the rooftops are thermally insulated by reflective cloth or thermal insulation boards. This type of renovation protection structure needs to be completely covered. During the construction process, due to differences in the operating levels of personnel, loose connections are prone to occur, and then local leakage occurs, resulting in inconsistent quality of the renovation project and failure to meet the acceptance standards. In addition, during the construction process, due to the installation of some basic equipment in the old residential communities, the equipment needs to be moved during the waterproofing and rooftop insulation process. After laying, it is returned to its original position and placed on the surface of the laid protective layer. This construction method will slow down the construction progress on the one hand, and on the other hand, it will damage the surface of the laid protective layer and easily cause local leakage. For the protective structure of the roof, although it can solve the functions of waterproofing and sun protection, holes will be drilled on the original building surface to connect various support frames during the construction process, causing secondary damage to the building. In addition, the cutting and welding efficiency of the erection process is low, the construction process is cumbersome and changeable, and the construction period is still long. Therefore, it is necessary to make improvements in this direction and propose a new solution to solve these problems in the renovation process.

[0029] See also Figures 1 to 7, is an assembled layered waterproof and cooling structure for a building roof disclosed in an embodiment of the present application, including a building body 29, characterized in that it also includes: a connecting base 1, a connecting hole 2, a support shaft 3, a fastening component 4, an insulation board 5, a pressing block 6, a connecting screw 7, a connecting rod 8, a mounting sleeve 9, a support rod 10, a support frame 11, a protective plate 12, a fastening rod 13, a sealing plate 14, a pad A15, a pad B16 and a door body 17, the connecting base 1 is respectively arranged on the upper surface of the four corners of the building body 29, the connecting holes 2 are respectively opened at the upper ends of the connecting bases 1, the lower ends of the support shafts 3 are respectively connected with the connecting holes 2, the fastening component 4 has an L-shaped appearance, the bending positions of the fastening component 4 are respectively connected with the middle positions of the support shafts 3, the insulation board 5 is surrounded into a rectangle, the corners of the insulation board 5 are respectively connected to the connecting base 1, and the pressing blocks 6 are respectively connected to the connecting base 1 On the upper part, the ends of the clamping blocks 6 are respectively in contact with the corresponding insulation boards 5, the connecting screws 7 are respectively connected with the fastening components 4, two connecting rods 8 are provided, and the ends of the connecting rods 8 are respectively connected to the upper ends of the support shafts 3, the mounting sleeves 9 are equidistantly sleeved on the connecting rods 8, and the support rods 10 are respectively fixedly connected to the upper ends of the mounting sleeves 9. The appearance of the support frame 11 is several inverted V shapes, and the lower surfaces of the support frames 11 are respectively fixedly connected to the upper ends of the support rods 10, the protective plates 12 are fixedly connected to the upper surface of the support frames 11, the fastening rods 13 are respectively fixedly connected to the lower surfaces of the mounting sleeves 9 on both sides, the sealing plate 14 is fixedly connected to the lower surface of the fastening rods 13, and the lower surface of the sealing plate 14 contacts the upper ends of the insulation boards 5, the pad A15 is arranged at the lower end of the longer insulation board 5, the pad B16 is arranged at the lower end of the shorter insulation board 5, and the door bodies 17 are respectively arranged in the middle position of the longer insulation boards 5.

[0030] Specifically, the connection base 1 is rectangular in appearance, and the connection form adopts rivets, anchor grouting and the like to realize the connection between the connection base 1 and the building body 29. The key point of the overall installation is that the setting position of the connection base 1 needs to be near the four corners of the top of the building body 29, so as to form the main positioning point for the next step of installation. If the position is offset, the subsequent components will deviate after installation, affecting the subsequent construction progress. The connection hole 2 is set to connect the lower end of the support shaft 3. During the installation of the two, grouting or glue can be injected into the gap between the connection to keep the position stable after the connection. The support shaft 3 can provide sufficient support. The heat insulation panels 5 surround the rectangular structure and are symmetrically arranged in pairs, and the corner positions of the two sides are respectively matched. It is connected to the connecting base 1, which can support its end. The fastening assembly 4 can be connected to the middle of the surrounding insulation board 5 through the connecting screws 7, further improving the stability of the insulation board 5.

Among the connection forms of the two, detachable connections such as screws are preferably used, which helps to improve the later material upgrade and leave space for operations such as replacing protective materials. The set connecting rod 8 is preferably set on one side of the longer side of the building body 29, and its two ends are respectively connected to the support shaft 3. In terms of connection method, various existing matching quick-connect structures can be used as needed. That is, it is necessary to ensure that the support shaft 3 is firmly connected to the connecting rod 8 and can withstand the force at the upper end. The installed installation sleeve 9 can be installed according to the specific construction area, and then the support rod 10 thereon can continuously connect the top support frame 11 to form a ridge support frame, which is convenient for connecting the upper end protection plate 12. The installed protection plate 12 can be made of an existing color steel tile structure or a plate based on the insulation board 5. Here, the protection plate 12 mainly plays a role in diverting rainwater, while preventing light from directly shining on the upper surface of the building body 29. It also has a certain cooling effect, but does not have a heat preservation function. The installed fastening rod 13 can connect the installation sleeves 9 on both sides, thereby improving its stability and ensuring the overall The firmness of the structure, and the sealing plate 14 connected to its lower surface can seal the upper end of the insulation board 5 to form a cavity structure. In terms of material selection, the sealing plate 14 can also be made of insulation board, thereby forming a relatively closed isolation space at the upper end of the building body 29. There is a certain space between the upper end of the space and the protective plate 12, which facilitates the normal flow of gas, can have a cooling effect in summer, and have a heat preservation effect in winter. The setting of the pad B16 and the door body 17 can fill the gap between the lower end of the insulation board 5 and the upper surface of the building body 29 to avoid gas convection at the bottom, and at the same time can support the insulation board 5 and disperse the force on the connection base 1, which is fast for the renovation and repair of the roof of the existing building body 29.It saves construction time and achieves more stable use.

[0032] Specifically, in the use of the insulation board 5, porous insulation materials such as polyurethane are preferably used. The installation hole 51 is provided during the setting process of the insulation board 5 structure to facilitate the connection of the reinforcing rod 54, thereby improving the strength of the entire insulation board 5. After installation, it has a higher degree of firmness, which helps to ensure stability during subsequent use. Compared with existing panels, it is more suitable for installation on the top floor. The provided matching protrusions 52 and matching female grooves 53 can quickly splice the two insulation boards 5, making them smoother after connection, and the appearance is improved.

[0038] Specifically, the placement platform 20 can be used to place the connection between the two insulation boards 5 to ensure a good degree of flatness. The support platform A21 and the support platform B22 provided thereon can respectively firmly connect the pressing block 6. Their positions are not on the same horizontal plane in the setting, which can avoid the phenomenon of reduced strength caused by the connection positions of the insulation boards 5 being at the same height, thereby helping to extend the service life and ensure the connection strength.

[0039] See also Figure 7 As another specific embodiment provided in the application, it also includes a matching notch A23 and a matching notch B24.

[0044] Specifically, the setting of the limiting platform 26 can support the fastening assembly 4 so that it is connected at the same position, which is convenient for positioning and improves convenience.

[0045] See also Figure 3 As another specific embodiment provided by the application, it also includes edge guard plates 27, which are fixedly connected to the surfaces of both ends of the protective plate 12.

[0046] Specifically, the edge guard plate 27 can support the end of the protective plate 12, thereby improving its protective effect and completely covering the entire upper surface of the building body 29.

[0047] See also Figure 2 As another specific embodiment provided in the application, it also includes a matching portion 28, which is respectively opened at the upper end of the support shaft 3, and the cross-section of the matching portion 28 is polygonal.

[0048] Specifically, the matching portion 28 is configured as a polygon, which can enhance stability after installation and is more convenient for firm connection than a circular rod, meeting the needs of actual scenarios.
