Description

Technical Field

[0001] The utility model belongs to the technical field of ancient buildings, and in particular relates to a flat roof of a quadrangle courtyard. Background Art

[0002] Siheyuan, also known as Sihefang, is a traditional courtyard-style building in China. Its layout is a courtyard with houses built on all four sides, enclosing the courtyard in the middle from all four sides, hence the name Siheyuan;

[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 flat roof of the traditional courtyard house, blue ash back, hemp ash back or broadsword white ash back, mud back, guard plate ash and wooden lookout board are arranged in sequence from top to bottom. The ash back and mud back are used to achieve thermal insulation, waterproofing and heat insulation of the roof. However, 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 flat roof, aiming to solve the problem that the courtyard flat roof in the prior art realizes the heat preservation, waterproofing and heat insulation of the roof by means of ash back and mud back, and its heat preservation and waterproofing effects are not good. After a long time, the heat preservation 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 flat roof comprises a wooden lookout board, an anti-corrosion layer, a thermal insulation layer, a slope layer, a leveling layer, a waterproof layer, an isolation layer and a mortar layer which are arranged in sequence from bottom to top.

[0008] In a preferred embodiment of the present utility model, the anti-corrosion layer is made of hemp ash.

[0009] In a preferred embodiment of the present invention, the thermal insulation layer is an extruded polystyrene board thermal insulation layer.

[0010] In a preferred embodiment of the present invention, the slope leveling layer is a 2% slope leveling layer of LC5.0 lightweight aggregate concrete with a thickness of at least 30 mm.

[0011] In a preferred embodiment of the present invention, the waterproof layer is a 3+3mm thick double-layer self-adhesive tire SBS modified asphalt waterproof membrane.

[0012] The beneficial effects of the utility model are:

[0013] 1. The flat roof designed by the utility model includes a waterproof layer and an isolation layer. The waterproof layer is made of a 3+3mm thick double-layer SBS modified asphalt waterproof membrane. The 3+3mm thick double-layer SBS modified asphalt waterproof membrane and the isolation layer cooperate with each other, which can greatly improve the waterproof performance of the flat roof and effectively avoid roof leakage. The SBS modified asphalt waterproof membrane has good elongation performance and a long service life, which can effectively avoid roof leakage for a long time.

[0014] 2. The flat roof designed by the utility model includes an insulation layer, which is an extruded polystyrene board insulation layer. Since the closed-cell rate of the extruded polystyrene board is as high as over 90%, it has good thermal insulation performance. The thickness of the extruded polystyrene board is based on the energy-saving calculation of each project. Compared with traditional technology, the extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good thermal insulation and energy-saving effects. Since the extruded polystyrene board itself has poor water absorption performance, it can also further achieve a waterproof technical effect. At the same time, the isolation layer is located above the extruded polystyrene board insulation layer, which can not only ensure the stability of the extruded polystyrene board insulation layer, but also play a certain role in moisture-proof, waterproof and mildew-proof.

[0015] 3. The flat roof designed by the utility model includes a mortar layer, which is smoothed with hydrophobic expanding bead mortar, and a layer of fiberglass mesh cloth is pressed in the middle. The seams are 3m*3m and filled with sealing paste. The fiberglass mesh cloth makes the impact resistance of the insulation layer reach the highest point and can resist the temperature difference of the outside, further ensuring the insulation and energy-saving effects in the courtyard house.

[0019] 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.

[0020] Embodiment 1:

[0021] like Figure 1-2 As shown, this embodiment provides a courtyard flat roof, including a wooden lookout board 1, an anti-corrosion layer 2, an insulation layer 3, a slope layer 4, a leveling layer 5, a waterproof layer 6, an isolation layer 7 and a mortar layer 8 arranged in sequence from bottom to top.

[0022] Specifically, the insulation layer 3 is bonded to the wooden fascia board 1 to ensure the stability of the insulation layer 3. The insulation layer 3 is used to improve the insulation and energy-saving performance of the flat roof of the courtyard house. The waterproof layer 6 is used to improve the waterproof performance of the flat roof of the courtyard house, thereby improving the livability of the courtyard house without changing the overall architectural form of the courtyard house.

[0023] In this embodiment, the anti-corrosion layer 2 is made of hemp ash and has a thickness of 20 mm.

[0024] Specifically, the anti-corrosion layer 2 is mainly used to protect the wooden lookout board 1. The ash of hemp ash is relatively soft and can play an anti-corrosion role, thereby extending the service life of the wooden lookout board 1.

[0025] In this embodiment, the thermal insulation layer 3 is an extruded polystyrene board thermal insulation layer.

[0026] Specifically, because the closed-cell rate of extruded polystyrene board is as high as over 90%, it has good thermal insulation performance. The thickness of extruded polystyrene board is based on the energy-saving calculation of each project. Compared with traditional technology, extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good thermal insulation and energy-saving effects. At the same time, because the water absorption performance of extruded polystyrene board itself is poor, it can also achieve a waterproof technical effect.

[0027] Furthermore, the extruded polystyrene board adopts B1 grade extruded polystyrene board, which can achieve the technical effect of fire retardancy.

[0028] In this embodiment, the slope leveling layer 4 is a 2% slope leveling layer of LC5.0 lightweight aggregate concrete with a thickness of 30 mm at the thinnest.

[0029] Specifically, taking the roof area as 10*30=300㎡, use 10m width to calculate the slope first, that is, one end of 10m is O, and the other end is 10*2%=0.2m, then its average thickness is 100mm, and the thinnest part is 30mm, that is, its thickness is 130mm, 130mm is equal to 0.13m, and the subsequent leveling layer 5 project volume is 300㎡*0.13m=39m³.

[0030] In this embodiment, the leveling layer 5 is a 1:3 cement mortar leveling layer.

[0031] Specifically, a leveling layer 5 is provided on the slope layer 4 to facilitate installation of the waterproof layer 6 .

[0032] In this embodiment, the waterproof layer 6 is a 3+3 mm thick double-layer self-adhesive tire-coated SBS modified asphalt waterproof membrane.

[0033] Specifically, the additional layer uses 3mm similar roll materials. The SBS modified asphalt waterproof roll material has good elongation performance and long service life, which can effectively prevent roof leaks for a long time.

[0034] In this embodiment, the isolation layer 7 is a low-grade mortar isolation layer.

[0035] Specifically, the low-grade mortar isolation layer can play a certain role in waterproofing, moisture-proofing and mildew-proofing. The 3+3mm thick 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 flat roof and effectively avoid roof leaks.

[0036] In this embodiment, the mortar layer 8 is smoothed with hydrophobic swelling bead mortar, a layer of glass fiber mesh cloth is pressed in the middle, the seams are 3m*3m, and the seams are filled with sealing paste.

[0037] Specifically, the hydrophobic expanded beads can form an insulating layer, effectively reducing the temperature difference between the inside and outside of the building and achieving the technical effect of thermal insulation. A layer of glass fiber mesh cloth is pressed in the middle, so that the impact force of the thermal insulation layer 3 reaches the highest point, which is further able to resist the temperature difference from the outside, thereby ensuring the thermal insulation and energy-saving effects in the courtyard house.

[0038] Specifically, the working principle of the courtyard flat roof is as follows: a 20mm thick hemp ash is set on the top of the wooden board 1, which can play an anti-corrosion role and extend the service life of the wooden board 1. The insulation layer 3 is bonded to the wooden board 1. The insulation layer 3 is an extruded polystyrene board insulation layer. Because the closed-pore rate of the extruded polystyrene board is as high as more than 90%, it has good thermal insulation performance. The use thickness of the extruded polystyrene board is based on the energy-saving calculation of each project. Compared with the traditional technology, the extruded polystyrene board can effectively alleviate the transfer of heat, thereby achieving good thermal insulation and energy-saving effects. At the same time, due to the poor water absorption performance of the extruded polystyrene board itself, the technical effect of waterproofing can also be achieved. The slope layer 4 and the leveling layer 5 are arranged in sequence on the extruded polystyrene board. The leveling layer 5 is a 1:3 cement mortar leveling layer, which is convenient for installing the waterproof layer 6. The waterproof layer 6 is 3+3 A 3+3mm thick double-layer self-adhesive SBS modified asphalt waterproof membrane is used. An isolation layer 7 is arranged above the waterproof layer 6. The isolation layer 7 is a low-grade mortar isolation layer. The 3+3mm thick double-layer self-adhesive SBS modified asphalt waterproof membrane and the low-grade mortar isolation layer cooperate with each other to greatly improve the waterproof performance of the flat roof and effectively avoid roof leakage. A mortar layer 8 is arranged above the isolation layer 7. The mortar layer 8 is smoothed with hydrophobic swelling bead mortar, and a layer of fiberglass mesh cloth is pressed in the middle. The seams are 3m*3m and filled with sealing paste. The hydrophobic swelling beads can form an insulating layer, which effectively reduces the temperature difference between the inside and outside of the building and achieves the technical effect of thermal insulation. A layer of fiberglass mesh cloth is pressed in the middle, so that the resistance of the thermal insulation layer 3 reaches the highest point, which is further enough to resist the temperature difference from the outside, thereby ensuring the thermal insulation effect in the courtyard house.

[0039] Embodiment 2:

[0040] On the basis of Example 1, the waterproof layer 6 extends to the eaves of the flat roof connected to the flat roof, further playing a waterproof role, and a gray stainless steel sheet flashing and top pressure head is arranged on the eaves to divert rainwater to a farther end to prevent it from flowing to the wall under the brick eaves. A drip tile base 9 is arranged below the stainless steel sheet flashing, and a drip tile 10 is arranged on the side of the drip tile base 9 away from the flat roof. The drip tile 10 is connected to the eaves of the flat roof through the drip tile base 9, the drip tile base 9 is bonded to the flat roof, and anchor nails are added between the drip tile base 9 and the flat roof to ensure the stability of the drip tile base 9. At the same time, the outward extension length of the drip tile 10 is increased to ensure that the eaves and the outer wall of the courtyard are not washed by rainwater, and at the same time protect the waterproof layer of the outer wall of the courtyard, further preventing water from entering the outer wall of the courtyard.

[0041] 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.
