Description

Technical Field

[0001] This invention patent relates to the technical field of roof insulation, specifically to a roof insulation, crack-resistant, green, and energy-saving structure. Background Technology

[0002] As the top structure of a building, the rooftop is directly exposed to the external environment. Especially in the high temperatures of summer, the rooftop surface temperature rises significantly due to solar radiation, causing heat to accumulate indoors and reducing living comfort. Over time, this also affects the safe service life of the rooftop.

[0003] Therefore, rooftop insulation technology is of great significance for improving the overall performance of buildings and the living environment of top-floor residents.

[0004] In existing technologies, insulation materials such as bricks and insulation coatings have poor insulation performance and durability, and may have adverse effects on the environment and the health of residents. Moreover, in the existing insulation structure design, the separation of the insulation layer and the waterproof layer leads to unsatisfactory insulation effect, reduced durability of the waterproof layer, and easy leakage problems, making it difficult to meet the comprehensive needs of modern buildings for efficient insulation, energy saving and environmental protection, and structural safety. Summary of the Invention

[0005] The purpose of this invention is to provide a rooftop thermal insulation, crack resistance, green and energy-saving structure, aiming to solve the problem of poor rooftop thermal insulation performance in the existing technology.

[0006] The present invention is implemented as follows: a rooftop heat-insulating, crack-resistant, green and energy-saving structure includes a bottom cement mortar layer laid on the rooftop and multiple extruded polystyrene boards laid on the bottom cement mortar layer. The multiple extruded polystyrene boards are arranged in an array to form a board layer. A top cement mortar layer is laid on the board layer. An anti-slip layer is laid on the top cement mortar layer. The bottom cement mortar layer, the board layer, the top cement mortar layer and the anti-slip layer are combined into one unit.

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

[0008] Furthermore, the rooftop 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 2cm to 3cm.

[0011] Furthermore, the anti-slip layer includes multiple anti-slip bricks, which are laid in an array on the top cement mortar layer.

[0012] Furthermore, a wire mesh is laid on the board layer, and the wire mesh is fixed to the board layer as a whole, and the top cement mortar layer covers the wire mesh.

[0013] Furthermore, there are assembly gaps between adjacent extruded polystyrene boards, and the wire mesh has multiple mesh openings distributed throughout the entire wire mesh arrangement; the wire mesh has an outer perimeter wall surrounding the mesh openings, and the outer perimeter wall is arranged in a closed loop.

[0014] The top of the extruded board has a plurality of protrusions, which pass through the mesh and extend above the wire mesh. The outer wall surrounds the outer periphery of the protrusions and abuts against the outer periphery of the protrusions. The protrusions have longitudinal holes that pass through the top. The cement mortar of the top cement mortar layer fills the longitudinal holes and compresses the protrusions to deform radially.

[0015] Furthermore, there is an intersection between adjacent outer walls, and the intersection forms a hollow area. The hollow area is filled with an elastic block. The outer periphery of the elastic block is fixedly connected to the outer wall. The elastic block is connected to an insert. The upper end of the insert is fixedly connected to the elastic block, and the lower end of the insert is inserted into the assembly gap and clamped and fixed by the adjacent extruded polystyrene board.

[0016] Furthermore, the upper end of the insert has a conical head, and the diameter of the conical head gradually decreases along the height direction of the insert, and the conical head is enclosed in an elastic block.

[0017] Furthermore, the outer periphery of the extruded board has an outer peripheral sidewall facing the assembly gap, the middle part of the outer peripheral sidewall is recessed inward to form an outer peripheral groove, and the outer peripheral groove is arranged around the outer peripheral sidewall in a circumferential direction.

[0018] The extruded polystyrene board has multiple curved channels, which are arranged at intervals around the circumference of the extruded polystyrene board. The upper end of each curved channel penetrates the top of the extruded polystyrene board to form a top opening, and the lower end of each curved channel extends to the outer peripheral groove. Along the top-to-bottom direction of the curved channel, the curved channel is arranged to bend outwards.

[0019] The cement mortar in the top cement mortar layer fills the curved channels and assembly gaps through the top opening, thereby solidifying the extruded polystyrene board and the top cement mortar layer into a single unit at multiple locations.

[0020] Compared with existing technologies, the rooftop thermal insulation, crack resistance, green energy-saving structure provided by this invention has the following technical advantages:

[0021] 1) Extruded polystyrene board is used as a high-efficiency thermal insulation material. It has 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 room. By laying an extruded polystyrene board layer on the bottom cement mortar layer, a thermal insulation barrier is formed, thereby achieving a high-performance thermal insulation effect on the roof.

[0022] 2) The addition of resin powder enhances the flexibility of cement mortar and reduces cracks caused by temperature changes and loads; while the waterproofing agent effectively improves the waterproof performance of cement mortar and prevents rainwater penetration. This not only extends the service life of the roof structure, but also further improves the overall stability of the insulation layer and reduces the damage to the insulation layer and structural aging caused by cracks and water seepage.

[0023] 3) The bottom cement mortar layer, extruded polystyrene board layer, top cement mortar layer and anti-slip layer are combined into one, forming a strong integrated roof structure. This not only enhances the stability of the structure, but also simplifies the construction process and improves construction efficiency. In addition, the high-efficiency heat insulation performance of the extruded polystyrene board reduces the energy consumption for cooling in summer, and the added resin powder and waterproofing agent are all environmentally friendly materials, which meet the environmental protection requirements of modern buildings.

[0033] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0034] The rooftop heat insulation, crack resistance, green energy-saving structure includes a bottom cement mortar layer 100 laid on the rooftop and multiple extruded polystyrene boards 200 laid on the bottom cement mortar layer 100. The multiple extruded polystyrene 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, and 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 unit.

[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 cement mortar is cement: sand: water: waterproofing agent: resin powder = 1: 4.5: 0.8: 0.05: 0.04.

[0036] The aforementioned rooftop thermal insulation, crack-resistant, green, and energy-saving structure has the following technical advantages:

[0037] 1) Extruded polystyrene board 200 is used as a high-efficiency thermal insulation material. It has 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 room. Then, by laying an extruded polystyrene board 200 layer 101 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 and reduces cracks caused by temperature changes and loads; while the waterproofing agent effectively improves the waterproof performance of cement mortar and prevents rainwater penetration. This not only extends the service life of the roof structure, but also further improves the overall stability of the insulation layer and reduces the damage to the insulation layer and structural aging caused by cracks and water seepage.

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

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

[0041] By removing the rooftop, the adhesion between the bottom cement mortar layer 100 and the rooftop surface can be enhanced, thereby improving the stability and reliability of the entire insulation structure. This lays a solid foundation for the subsequent laying of the insulation layer and ensures that the insulation structure can better perform its insulation function.

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

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

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

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

[0046] In this embodiment, a wire mesh 102 is laid on the board 101, and the wire mesh 102 is fixed to the board 101 as a whole. The top cement mortar layer 103 covers the wire mesh 102.

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

[0048] In this embodiment, there is an assembly gap between adjacent extruded polystyrene boards 200, and the wire mesh 102 has multiple mesh holes, which are distributed throughout the entire wire mesh 102; the wire mesh 102 has an outer wall 202 surrounding the outer periphery of the mesh holes, and the outer wall 202 is arranged in a closed loop.

[0049] The top of the extruded polystyrene board 200 is raised to form multiple protrusions 201. The protrusions 201 pass through the mesh and extend above the wire mesh 102. The outer wall 202 surrounds the outer periphery of the protrusions 201 and abuts against the outer periphery of the protrusions 201. The protrusions 201 are provided with longitudinal holes that are open at the top. The cement mortar of the top cement mortar layer 103 fills the longitudinal holes and compresses the protrusions 201 to deform radially.

[0050] The presence of gaps in the assembly allows the extruded polystyrene boards 200 to better adapt to temperature changes and loads, avoiding structural damage caused by thermal expansion and contraction. The protrusions 201 passing through the perforated mesh and abutting against the outer wall 202, as well as the cement mortar filling the longitudinal holes and compressing the protrusions 201 to deform radially, further enhance the connection strength between the extruded polystyrene boards 200, the wire mesh 102, and the cement mortar layer, making the thermal insulation structure more stable and the thermal insulation performance more stable and reliable.

[0051] In this embodiment, there is an intersection between adjacent outer walls 202, and the intersection forms a hollow area. 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 insert 204. The upper end of the insert 204 is fixedly connected to the elastic block 203, and the lower end of the insert 204 is inserted into the assembly gap and 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 insert 204 is inserted into the assembly gap and clamped and fixed by the extruded polystyrene board 200, which further enhances the connection stability between the extruded polystyrene boards 200, prevents the extruded polystyrene boards 200 from shifting or loosening during use, thereby ensuring that the overall performance of the thermal insulation structure is not affected and improving the reliability and durability of the roof thermal insulation structure.

[0054] In this embodiment, a conical head 205 is formed at the upper end of the insert 204. Along the height direction of the insert 204, the diameter of the conical head 205 gradually decreases, and 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 it and the elastic block 203 becomes tighter, 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, ensuring the long-term stable operation of the thermal insulation structure.

[0056] In this embodiment, the outer periphery of the extruded board 200 has an outer peripheral sidewall facing the assembly gap, and the middle part of the outer peripheral sidewall is recessed inward to form an outer peripheral groove 206, which is arranged around the outer peripheral sidewall in a circumferential direction.

[0057] The extruded polystyrene board 200 has multiple curved channels 207, which are arranged around the circumference of the extruded polystyrene board 200 at intervals. The upper end of the curved channel 207 penetrates the top of the extruded polystyrene board 200 to form a top opening, and the lower end of the curved channel 207 extends to the outer peripheral groove 206. The curved channel 207 is arranged to bend outwards along the top-to-bottom direction.

[0058] The cement mortar of the top cement mortar layer 103 fills the curved channel 207 and the assembly gap through the top opening, so that the extruded board 200 is fixed to the top cement mortar layer 103 at multiple locations.

[0059] The outer peripheral groove 206 and the curved channel 207 provide more filling space and connection points for the cement mortar, enabling the extruded polystyrene board 200 to be consolidated with the cement mortar layer at multiple locations, forming a whole. This multi-location consolidation method not only improves the crack resistance and integrity of the thermal insulation structure, but also effectively prevents the extruded polystyrene board 200 from loosening or falling off during use, ensuring the long-term stable operation of the thermal insulation structure and significantly improving the thermal insulation performance of the roof.

[0060] The following will describe the technical solutions in the embodiments of the present invention in a specific, clear and complete manner, so as to make the content of the rooftop heat insulation, crack resistance and green energy-saving structure easier to understand.

[0061] Specific paving process:

[0062] 1) Lay a layer of M15 cement mortar at the bottom on the roof. Add auxiliary materials such as resin powder and waterproofing agent to the bottom cement mortar layer. The thickness of the bottom cement mortar layer is 2-3cm.

[0063] The cement mortar mix ratio is cement:sand:water:waterproofing agent:resin powder = 1:4.5:0.8:0.05:0.04.

[0064] 2) Make a slight slope during construction. When paving, pay attention to leaving 10-15 cm around the perimeter of the wall as a drainage ditch.

[0065] 3) Lay the extruded polystyrene board. The process is the same as laying tiles. Lay the extruded polystyrene board flat. It is especially important to note that in hot summer, construction should be carried out in the morning or evening. Remember that the construction and pouring time of the insulation layer should not be delayed for too long. When the temperature is too high and the ultraviolet rays are strong, the extruded polystyrene board is very easy to deform in a short time due to uneven heating on one side, which can cause great losses.

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

[0067] 4) After the top cement mortar layer has hardened, perform appropriate spray curing for 3 days.

[0068] 5) After the top cement mortar layer has been sprayed and cured, lay anti-slip and wear-resistant ceramic tiles on top, 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 within the protection scope of the present invention.
