[0002] The roof, as the top structure of the building, is directly exposed to the external environment. Especially in the hot weather in summer, it is exposed to solar radiation, and the surface temperature of the roof rises significantly, resulting in indoor heat accumulation, which reduces the living comfort. In the long run, it also affects the safety and service life of the roof.

Moreover, in the existing insulation structure design, the separation of the insulation layer and the waterproof layer leads to unsatisfactory insulation effects, reduced durability of the waterproof layer, and easy to cause problems such as leakage, which makes it difficult to meet the comprehensive needs of modern buildings for efficient insulation, energy conservation and environmental protection, and structural safety. Summary of the Invention

[0007] The bottom cement mortar layer and the top cement mortar layer are formed by laying cement mortar, and resin powder and waterproofing agent are mixed in the bottom cement mortar layer and the top cement mortar layer. According to the mass ratio, the ratio of the cement mortar is cement: sand: water: waterproofing agent: resin powder = 1:4.5:0.8:0.05:0.04.

[0008] Furthermore, the roof is removed to form a roof surface, and the bottom cement mortar layer is laid on the roof surface.

[0009] Furthermore, the thickness of the bottom cement mortar layer is 2cm to 3cm.

[0010] Furthermore, the thickness of the top cement mortar layer is 2 cm to 3 cm.

[0014] The top of the extruded board is raised to form a plurality of bumps, and the bumps pass through the mesh and extend to the top of the steel mesh. The outer wall surrounds the outer periphery of the bumps and abuts against the outer periphery of the bumps. A longitudinal hole is provided in the bump that passes through the top, and the cement mortar of the top cement mortar layer is filled in the longitudinal hole and squeezes the bump to deform radially.

[0033] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0034] The rooftop heat-insulating, crack-resistant, green and energy-saving structure includes a bottom cement mortar layer 100 laid on the rooftop and a plurality of extruded boards 200 laid on the bottom cement mortar layer 100. The plurality of extruded boards 200 are arranged in an array to form a board layer 101. A top cement mortar layer 103 is laid on the board layer 101. An anti-slip layer 104 is laid on the top cement mortar layer 103. The bottom cement mortar layer 100, the board layer 101, the top cement mortar layer 103 and the anti-slip layer 104 are integrated into one.

[0035] The bottom cement mortar layer 100 and the top cement mortar layer 103 are formed by laying cement mortar. The bottom cement mortar layer 100 and the top cement mortar layer 103 are mixed with resin powder and waterproofing agent. According to the mass ratio, the ratio of cement mortar is cement: sand: water: waterproofing agent: resin powder = 1:4.5:0.8:0.05:0.04.

[0036] The above-mentioned roof insulation, crack resistance, green energy-saving structure has the following technical advantages:

[0037] 1) Extruded board 200 is used as a highly efficient thermal insulation material with excellent thermal insulation performance. Its low thermal conductivity can effectively block the transfer of heat and reduce the conduction of heat from the roof surface to the interior. By laying a layer 101 of extruded board 200 on the bottom cement mortar layer 100, a thermal insulation barrier is formed, thereby achieving a high-performance thermal insulation effect on the roof;

[0038] 2) The addition of resin powder enhances the flexibility of cement mortar, reducing cracks caused by temperature changes and loads; while the waterproofing agent effectively improves the waterproof performance of cement mortar, preventing rainwater penetration. This not only extends the service life of the roof structure, but also further improves the overall stability of the insulation layer, reducing insulation damage and structural aging caused by cracks and water seepage;

[0039] 3) The bottom cement mortar layer 100, the extruded board 200 layer 101, the top cement mortar layer 103 and the anti-slip layer 104 are combined into one to form a roof structure with strong integrity, which not only enhances the stability of the structure, but also simplifies the construction process and improves the construction efficiency; in addition, the high-efficiency thermal insulation performance of the extruded board 200 reduces the energy consumption of cooling in summer, and the added resin powder and waterproofing agent are both environmentally friendly materials, which meet the environmental protection requirements of modern buildings.

[0040] In this embodiment, the roof is removed to form a roof surface, and the bottom cement mortar layer 100 is laid on the roof surface.

[0041] By scraping the roof, the bonding strength between the bottom cement mortar layer 100 and the roof surface can be enhanced, thereby improving the stability and reliability of the entire insulation structure, laying a solid foundation for the subsequent laying of the insulation layer, and ensuring that the insulation structure can better exert its insulation effect.

[0042] In this embodiment, the thickness of the bottom cement mortar layer 100 is 2 cm to 3 cm; the bottom cement mortar layer 100 in this thickness range can provide stable support for the extruded board 200 layer 101, and at the same time cooperate with the top cement mortar layer 103 to form an integral insulation structure, effectively blocking the transfer of heat and improving the insulation effect of the roof.

[0043] In this embodiment, the thickness of the top cement mortar layer 103 is 2cm to 3cm. Such a thickness setting forms a symmetrical structure with the bottom cement mortar layer 100, and can better cooperate with the bottom cement mortar layer 100 to jointly support the extruded board 200 layer 101, thereby improving the stability of the entire insulation structure. At the same time, the top cement mortar layer 103 of such thickness can effectively cover the extruded board 200 layer 101 to prevent it from being eroded and damaged by the external environment, further enhancing the durability of the insulation structure and ensuring the long-term stability of the roof insulation performance.

[0044] In this embodiment, the anti-slip layer 104 includes a plurality of anti-slip bricks, which are laid in an array on the top cement mortar layer 103 .

[0045] A plurality of anti-slip bricks are arranged in an array and laid on the top cement mortar layer 103 as an anti-slip layer 104. This can not only effectively prevent people from slipping when walking on the roof and improve the safety of the roof, but also will not affect the thermal insulation performance of the insulation structure. On the contrary, it can enhance the integrity of the insulation structure and make it more stable and durable.

[0046] In this embodiment, a steel mesh 102 is laid on the board layer 101 , the steel mesh 102 and the board layer 101 are solidified into one, and the top cement mortar layer 103 covers the steel mesh 102 .

[0047] When the top cement mortar layer 103 covers the wire mesh 102, the wire mesh 102 is tightly combined with the cement mortar layer, which strengthens the integrity and crack resistance of the entire insulation structure, enabling it to better withstand the influence of external loads and environmental changes, thereby improving the insulation effect of the roof.

[0048] In this embodiment, there is an assembly gap between adjacent extruded plates 200, and the steel mesh 102 has a plurality of meshes, which are arranged throughout the entire steel mesh 102; the steel mesh 102 has an outer wall 202 surrounding the outer periphery of the meshes, and the outer wall 202 is arranged in a closed loop.

[0049] The top of the extruded board 200 is raised to form a plurality of bumps 201, which pass through the mesh and extend to the top of the wire mesh 102. The outer wall 202 surrounds the outer periphery of the bump 201 and abuts against the outer periphery of the bump 201. A longitudinal hole is provided in the bump 201 with the top passing through. The cement mortar of the top cement mortar layer 103 is filled in the longitudinal hole, and the bump 201 is squeezed to deform radially.

[0050] By utilizing the existence of the assembly gap, the extruded boards 200 can better adapt to temperature changes and loads, avoiding structural damage caused by thermal expansion and contraction; wherein, the protrusion 201 passes through the hole mesh and abuts against the outer wall 202, and the cement mortar is filled in the longitudinal hole and squeezes the protrusion 201 to deform radially, which further enhances the connection strength between the extruded board 200 and the wire mesh 102 and the cement mortar layer, making the insulation structure more stable and the insulation performance more stable and reliable.

[0051] In this embodiment, there is an intersection between adjacent outer walls 202, and a hollow area is formed at the intersection. The hollow area is filled with an elastic block 203. The outer periphery of the elastic block 203 is fixedly connected to the outer wall 202. The elastic block 203 is connected to an insertion strip 204. The upper end of the insertion strip 204 is fixedly connected to the elastic block 203, and the lower end of the insertion strip 204 is inserted into the assembly gap and is clamped and fixed by the adjacent extruded board 200.

[0052] The elastic block 203 can effectively absorb and disperse the stress caused by external loads and temperature changes, reducing the risk of structural deformation and damage;

[0053] The inserts 204 are inserted into the assembly gaps and are clamped and fixed by the extruded boards 200, further enhancing the connection stability between the extruded boards 200 and preventing the extruded boards 200 from being displaced or loosened during use, thereby ensuring that the overall performance of the insulation structure is not affected and improving the reliability and durability of the roof insulation structure.

[0054] In this embodiment, a conical head 205 is formed at the upper end of the cutting strip 204 . The diameter of the conical head 205 gradually decreases along the height direction of the cutting strip 204 . The conical head 205 is wrapped in the elastic block 203 .

[0055] As the diameter of the conical head 205 gradually decreases, the wrapping relationship between the conical head 205 and the elastic block 203 becomes tighter, thereby enhancing the connection strength and stability between the insert 204 and the elastic block 203. This not only improves the fixing effect of the insert 204, but also effectively prevents the insert 204 from loosening or falling off due to external forces during use, thereby ensuring the long-term stable operation of the thermal insulation structure.

[0056] In this embodiment, the outer periphery of the extruded plate 200 has an outer peripheral side wall facing the assembly gap, and the middle portion of the outer peripheral side wall is recessed inward to form an outer peripheral groove 206. The outer peripheral groove 206 is arranged around the circumference of the outer peripheral side wall.

[0057] The extruded plate 200 is provided with a plurality of curved channels 207 , which are arranged around the circumference of the extruded plate 200 at intervals. The upper ends of the curved channels 207 penetrate the top of the extruded plate 200 to form a top opening, and the lower ends of the curved channels 207 extend to the peripheral groove 206 . The curved channels 207 are arranged to bend outward from top to bottom.

[0058] The cement mortar of the top cement mortar layer 103 passes through the top opening and fills the curved path 207 and the assembly gap, so that the extruded board 200 and the top cement mortar layer 103 are consolidated into one at multiple positions.

[0059] By setting the peripheral groove 206 and the curved path 207, more filling space and connection points are provided for the cement mortar, so that the extruded board 200 and the cement mortar layer are consolidated at multiple positions to form a whole. This multi-position consolidation method not only improves the crack resistance and integrity of the insulation structure, but also effectively prevents the extruded board 200 from loosening or falling off during use, ensuring the long-term stable operation of the insulation structure and significantly improving the insulation performance of the roof.

[0060] Hereinafter, the technical solutions in the embodiments of the present invention will be described in detail, clearly and completely in combination with the embodiments of the present invention, so that the contents of the roof insulation, crack resistance, green and energy-saving structure are easier to understand.

[0061] Specific paving process:

[0062] 1) Wet-lay a bottom cement mortar layer M15 on the roof. Add auxiliary materials resin powder and waterproofing agent to the bottom cement mortar layer. The bottom cement mortar layer should be paved with a thickness of 2 to 3 cm.

[0063] Among them, the ratio of cement mortar is cement: sand: water: waterproofing agent: resin powder = 1:4.5:0.8:0.05:0.04.

[0064] 2) Create a slope during construction and pay attention to leaving 10 to 15 centimeters around the wall for drainage ditches when paving.

[0065] 3) Spread the extruded board. Use the same process as laying tiles. Pay special attention to the fact that construction should be carried out in the morning and evening in hot summer. Remember that the pouring time of the insulation layer should not be delayed too long. When the temperature is too high and the ultraviolet rays are strong, the extruded board will be easily deformed in a short time due to uneven heating on one side, causing great losses.

[0066] After the extruded board is laid flat, lay the wire mesh on the extruded board, and then wet-lay a layer of top cement mortar layer M15. The top cement mortar layer is mixed with auxiliary materials resin powder and waterproofing agent. The top cement mortar layer is paved with a thickness of 2 to 3 cm, and the mix ratio is the same as above.

[0067] 4) After the top cement mortar layer hardens, carry out appropriate spray curing for 3 days.

[0068] 5) Spray the cured top cement mortar layer, lay anti-slip and wear-resistant tiles on the upper layer, and measure the flatness and a certain slope.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
