[0003] With the development of society, the livability of the traditional courtyard house has been challenged, so modern high-rise buildings have replaced the traditional courtyard house. However, as a traditional Chinese building, the architectural form of the traditional courtyard house has the significance of inheritance. Therefore, the new courtyard house came into being, which can not only inherit the ancient architecture but also improve the livability of the courtyard house.

[0004] When building the sloping roof of a traditional courtyard house, it includes a base layer, a plaster backing layer, a blue-lime backing layer, a funny mud backing layer, a guard plate ash layer and a wooden lookout board layer, which are arranged in sequence from top to bottom. The plaster backing layer, the blue-lime backing layer and the funny mud backing layer are used to achieve thermal insulation and waterproofing, but the thermal insulation and waterproofing effects are not good. After years, the thermal insulation effect in the house decreases and the roof is prone to leaks. Utility Model Content

[0005] The utility model aims to provide a courtyard house sloping roof, aiming to solve the problem that the courtyard house sloping roof in the prior art achieves thermal insulation and waterproofing by mixing a plaster back layer, a blue-gray back layer and a funny mud back layer, but the thermal insulation and waterproofing effects are poor. After years, the thermal insulation effect in the house decreases and the roof is prone to water leakage.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A courtyard sloping roof comprises a roof tile layer, a tile cushion layer, a protective layer, a waterproof isolation layer, a waterproof layer, a leveling layer, a moisture-proof and heat-insulating layer, an anti-corrosion layer and a base layer which are arranged in sequence from top to bottom.

[0014] In a preferred embodiment of the present invention, the moisture-proof and heat-insulating layer is made of extruded polystyrene board.

[0015] In a preferred embodiment of the present invention, the anti-corrosion layer is made of plate ash or 1:3 cement mortar.

[0016] In a preferred embodiment of the present invention, the base layer is made of wooden planks or reinforced concrete.

[0017] The beneficial effects of the utility model are:

[0018] 1. The sloped roof designed by the utility model includes a waterproof isolation layer and a waterproof layer. The waterproof isolation layer is a low-grade mortar isolation layer. The waterproof layer adopts a 3+3 thick double-layer self-adhesive tire SBS modified asphalt waterproof membrane. The low-grade mortar isolation layer and the double-layer self-adhesive tire SBS modified asphalt waterproof membrane cooperate with each other, which can greatly improve the waterproof and fireproof performance of the sloped roof and effectively avoid roof leakage.

[0019] 2. The sloping roof designed by the utility model includes a moisture-proof and heat-insulating layer, which is an extruded polystyrene board. Since the closed-cell rate of the extruded polystyrene board is as high as over 90%, it has good thermal insulation performance. Compared with traditional technology, the extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good thermal insulation, energy saving and environmental protection effects. At the same time, since the extruded polystyrene board itself has poor water absorption performance, it can also further achieve a waterproof technical effect.

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment provides a courtyard sloping roof, which is used for sloping roofs with higher elevations of "seven beams" or above, including a roof tile layer 1, a tile cushion layer 2, a protective layer 3, a waterproof isolation layer 4, a waterproof layer 5, a leveling layer 6, a moisture-proof and heat-insulating layer 7, an anti-corrosion layer 8 and a base layer 9 arranged in sequence from top to bottom.

[0026] Specifically, the protective layer 3 can improve the seismic resistance of the sloping roof and enhance the bearing and bonding capacity of the overall structure of the sloping roof. The waterproof isolation layer 4 and the waterproof layer 5 cooperate with each other to improve the waterproof performance of the sloping roof, which can effectively avoid roof leakage. The moisture-proof and thermal insulation layer 7 is used to achieve energy saving, heat preservation and environmental protection in the courtyard house.

[0027] In this embodiment, the roof tile layer 1 is filled with horizontal tile mortar (each tile of the cylindrical tile roof is firmly tied with No. 12 copper wire and steel mesh), and the joints are grouting with lime mortar.

[0028] In this embodiment, the tile cushion layer 2 is made of 20mm thick 1:1:4 cement lime mortar plus 3% hemp mortar by weight of cement.

[0029] In this embodiment, the protective layer 3 uses 40 thick pebble concrete, with %% c4@150*150 bidirectional, full-length across the ridge, and fully covered with steel mesh, covering at least two-thirds of the slope length of the roof.

[0030] Specifically, setting a steel mesh inside the pebble concrete can further enhance the bearing capacity of the pebble concrete, and combining it with copper wire and tile hanging strips to firmly connect and tie the tile surface can further enhance the bearing and bonding capacity of the roof, prevent the tile surface from sliding, make the tile surface more firmly tied and fixed, and ensure the overall stability of the courtyard slope roof.

[0031] In this embodiment, the waterproof isolation layer 4 is a 10mm thick low-grade mortar isolation layer.

[0032] Specifically, the low-grade mortar isolation layer is made of a mixture of raw materials such as cement, lime, and sand. It has excellent water-proof, moisture-proof, and heat-insulating functions, and can effectively reduce the passage of media such as water molecules.

[0033] In this embodiment, the waterproof layer 5 is made of a 3+3 thick double-layer self-adhesive SBS modified asphalt waterproof membrane, and the additional layer is made of a 3mm thick similar membrane.

[0034] Specifically, the waterproof layer 5 is made of a 3+3mm thick double-layer self-adhesive SBS modified asphalt waterproof membrane. The self-adhesive SBS modified asphalt waterproof membrane has good elongation and fire resistance and a long service life. The double-layer SBS modified asphalt waterproof membrane and the low-grade mortar isolation layer cooperate with each other to greatly improve the waterproof performance of the sloping roof and effectively avoid roof leakage for a long time.

[0035] In this embodiment, the leveling layer 6 is a 20mm thick 1:3 cement mortar leveling layer.

[0036] Specifically, a 20mm thick 1:3 cement mortar leveling layer is used to facilitate the installation of the waterproof layer 5 and improve the compactness of the waterproof layer.

[0037] In this embodiment, the moisture-proof and heat-insulating layer 7 is made of extruded polystyrene board bonded with heat-insulating board bonding mortar, and has a combustion performance of B1 level.

[0038] Specifically, because the closed-cell rate of extruded polystyrene board is as high as over 90%, it has good thermal insulation performance. Compared with traditional technology, extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good thermal insulation, energy saving and environmental protection effects. At the same time, because the extruded polystyrene board itself has poor water absorption performance, it can also further achieve a waterproof technical effect.

[0039] Furthermore, the extruded polystyrene board adopts B1 grade extruded polystyrene board, and the insulation board is bonded with mortar, and the bonding can achieve the technical effect of fire retardancy.

[0040] Furthermore, the thickness of the extruded polystyrene board is based on energy saving calculations.

[0041] In this embodiment, the anti-corrosion layer 8 is made of protective board ash (hemp knife ash), which is slightly softer and mainly used to protect the lookout board and play an anti-corrosion role. The thickness is 20 mm. The hemp knife ash can also prevent the cement mortar from falling off, improve the adhesion between the extruded polystyrene board and the wooden lookout board, and then use the insulation board bonding mortar to stick the extruded polystyrene board more firmly.

[0042] In this embodiment, the base layer 9 is made of wooden planks or reinforced concrete.

[0043] Specifically, when the base layer 9 is made of reinforced concrete, a 20mm thick 1:3 cement mortar is used for leveling, and there is no need to provide an anti-corrosion layer 8.

[0044] When the base layer 9 uses wooden lookout boards, the wooden lookout boards should be 20 thick and fire-proof and anti-corrosion treatments should be taken.

[0045] Furthermore, all wooden components should first be coated with three coats of CCA water-borne wood preservative, and then coated with two coats of wood flame retardant. All wooden components embedded in the walls and inside should be fully coated with asphalt for corrosion protection.

[0046] Specifically, the working principle of this courtyard house for the sloping roof with "seven beams" and above is: the guard plate ash is spread on the wooden lookout board, mainly to protect the lookout board, play an anti-corrosion role, and extend the service life of the wooden lookout board. The hemp knife ash can also prevent the cement mortar from falling and improve the adhesion between the extruded polystyrene board and the wooden lookout board. The extruded polystyrene board is more firmly bonded to the anti-corrosion layer 8 with the insulation board bonding mortar. The closed-cell rate of the extruded polystyrene board is as high as more than 90%, and it has good thermal insulation performance. Compared with traditional technology, the extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good insulation, energy saving, and environmental protection effects. A 1:3 cement mortar leveling layer 6 is set above the extruded polystyrene board for leveling, which is convenient for installing the waterproof layer 5 and improving the compactness of the waterproof layer. The waterproof layer 5 is made of a 3+3mm thick double-layer self-adhesive tire SBS modified asphalt waterproof membrane. The self-adhesive tire SBS modified asphalt waterproof membrane has good extension and fire resistance and a long service life. A waterproof isolation layer 4 is arranged above the waterproof layer 5, and the waterproof isolation layer 4 is a low-grade mortar isolation layer. The low-grade mortar isolation layer and the double-layer self-adhesive tire SBS modified asphalt waterproof membrane cooperate with each other, which can greatly improve the waterproof and fireproof performance of the slope roof, and can effectively avoid the occurrence of roof leakage for a long time. A pebbled concrete protective layer 3 is arranged above the waterproof isolation layer 4, and the pebbled concrete can improve the seismic performance of the courtyard slope roof and enhance the bearing capacity of the overall structure of the courtyard slope roof. A steel mesh is arranged inside the pebbled concrete, and copper wire, tile hanging strips and tile surface are connected and tied firmly, which can further enhance the bearing and bonding capacity of the roof, prevent the tile surface from sliding, make the tile surface binding and fixing more firmly, and ensure the overall stability of the courtyard slope roof.

[0047] Embodiment 2:

[0048] The present embodiment provides a courtyard sloping roof, which is used for sloping roofs with lower frames below the "seven beams". Different from Example 1, in Example 2, a steel mesh is fully laid in a 30-mm-thick 1:3 cement mortar above the waterproof isolation layer 4, and the overlapped parts are tied with No. 18 galvanized steel wire. It is fully laid across the ridge and covers at least two-thirds of the slope length of the roof, replacing the pebble concrete protective layer 3 in Example 1.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
