[0021] The following will be combined with the attached Figure 1 -Attached Figure 5 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0022] The inventor of this application has found that the traditional roof construction method has problems such as long construction period, high consumables, and low construction efficiency. To this end, this application discloses a thermal insulation integrated assembled roof structure and its construction method, which mainly adopts the following scheme: The present application discloses a thermal insulation integrated assembled roof structure. Figure 1 , 2 , including a supporting frame 1, an insulating layer 2, a waterproof layer 3 and a concrete protective layer 4, wherein the supporting frame 1 is fixed on the main structure of the building, the insulating layer 2 includes a plurality of roof panels 21 spliced ​​together and installed on the supporting frame 1, the waterproof layer 3 is laid on the insulating layer 2 and covers the entire insulating layer 2, and the concrete protective layer 4 is laid on the waterproof layer 3; by processing the roof panels 21, the waterproof layer 3 and the supporting frame 1 and other components in the factory and then transporting them to the construction site for assembly, efficient assembly construction can be achieved, which can significantly shorten the construction period, reduce the amount of on-site work, and improve construction efficiency.

[0023] Reference Figure 2 , 3The roof panel 21 is made of high-strength lightweight concrete, and an insulation board 22 is embedded in the roof panel 21. The insulation board 22 is made of extruded polystyrene foam material or polyurethane foam material. A protrusion 211 is fixedly provided on the side wall of the roof panel 21, and a groove 212 is provided on the side wall of the roof panel 21 away from the protrusion 211. The protrusion 211 is adapted to the groove 212. When the roof panels 21 are spliced, the protrusion 211 on the roof panel 21 and the groove 212 on the adjacent roof panel 21 are engaged with each other, which can ensure the tight splicing between the roof panels 21. After the splicing of the roof panels 21 is completed, sealant is applied to the joints of the adjacent roof panels 21 to further improve the connection strength between the adjacent roof panels 21 and improve the waterproof sealing effect between the adjacent roof panels 21.

[0024] Reference Figure 2 After the roof panels 21 are laid, the roof panels 21 are spaced apart from the roof of the main structure of the building, so that a cavity 5 is formed between the insulation layer 2 and the roof of the main structure of the building, which can effectively reduce heat transfer, enhance the thermal insulation performance of the roof, and reduce the roof load and extend the service life of the roof. Further, when all the roof panels 21 are spliced, sealant is applied to the joints between the roof panels 21 and the support frame 1 to increase the waterproof sealing effect between the roof panels 21 and the support frame 1.

[0025] Reference Figure 1 , 2 The waterproof layer 3 adopts modified asphalt waterproof membrane. When laying the waterproof layer 3, a layer of sealant is coated on the surface of the thermal insulation layer 2. Then, the modified asphalt waterproof membrane is laid on the thermal insulation layer 2 to form the waterproof layer 3, and ensure that the waterproof layer 3 is laid flat and free of bubbles.

[0026] Reference Figure 2 The concrete protective layer 4 is formed by pouring fine stone concrete on site, and when the concrete protective layer 4 is poured, the fine stone concrete fills the gap between the support frame 1 and the main structure of the building. After the concrete protective layer 4 is poured, it is necessary to maintain the concrete protective layer 4 to ensure that the concrete protective layer 4 reaches the designed strength before being put into use.

[0027] Reference Figure 1 , 2The edge of the concrete protective layer 4 is provided with a drainage ditch 41 along the circumference of the concrete protective layer 4. The drainage ditch 41 is connected to a drainage pipe 42. The setting of the drainage ditch 41 can effectively drain the water on the roof, avoiding water seepage on the roof and damage to the roof. Furthermore, the top wall of the concrete protective layer 4 is high in the middle and low around, and a water guide slope is formed on the top wall of the concrete protective layer 4. The water guide slope is connected to the drainage ditch 41. The setting of the water guide slope can effectively guide rainwater to the drainage ditch 41, preventing water from staying on the roof for a long time, thereby avoiding roof leakage and structural damage. At the same time, the design of the water guide slope can also improve the overall drainage efficiency of the roof and reduce the safety hazards caused by water on the roof.

The ends of the beams 12 are fixed with plug-in blocks 121. The side walls of the columns 11 are provided with plug-in slots 111 for the plug-in blocks 121 to be inserted. Usually, one column 11 needs to be connected to multiple beams 12, so multiple plug-in slots 111 are usually provided on the columns 11. The support frame 1 is assembled by multiple columns 11 and beams 12, which is convenient for transportation. The support frame 1 can be quickly assembled on site, which greatly shortens the construction time.

The top of the column 11 is provided with a mounting groove 112 for inserting the bayonet 13 along the length direction of the column 11. The mounting groove 112 is adapted to the bayonet 13. The mounting groove 112 is connected to each plug-in slot 111. At least one clamping portion 131 is provided on the bayonet 13. The clamping portion 131 corresponds one-to-one to the plug-in slot 111 on the column 11. The plug-in block 121 is provided with a clamping slot 122 for inserting the clamping portion 131. The clamping slot 122 is adapted to the clamping portion 131.

[0030] Reference Figure 5The top wall of the column 11 is provided with a threaded hole matched with the locking bolt 14, and the bayonet 13 is provided with a through hole for the locking bolt 14 to pass through. When the bayonet 13 is fully inserted into the installation groove 112, the threaded hole is directly opposite to the through hole on the bayonet 13, and when the bayonet 13 is inserted into the installation groove 112 on the column 11, each clamping portion 131 is respectively located in the corresponding plug-in groove 111 and inserted into the clamping groove 122 on the plug-in block 121, and then the bayonet 13 is fixed by the locking bolt 14, thereby preventing the plug-in block 121 from being separated from the plug-in groove 111 of the column 11. In addition, by providing multiple clamping portions 131 on the bayonet 13, the plug-in blocks 121 on multiple beams 12 can be fixed at the same time, thereby improving the convenience of installation.

[0031] Reference Figure 4 , 5 The side wall of the cross beam 12 is fixedly provided with a pedestal 123, and the pedestals 123 on each cross beam 12 together form a placement groove 15 for placing the roof panel 21. The roof panel 21 can be stably placed on the support frame 1, the installation accuracy and stability of the roof panel 21 are improved, and the installation process is simplified, reducing the construction difficulty.
