[0039] In the renovation of old buildings, the renewal of the roof system is a key link to improve building performance and extend its service life. Flat-to-slope and slope roof renovation are the most common forms of renovation; among them, slope roof renovation usually involves multiple independent construction steps, including the construction of waterproof layer, thermal insulation layer and protective layer separately, which is not only time-consuming, but also increases the difficulty and cost of construction.

[0040] In order to solve the above problems, the present invention proposes a roof reconstruction structure.

[0041] See also Figures 1 to 8 In one embodiment of the present invention, the roof reconstruction structure includes a first module component 1 and a second module component 2, the first module component 1 includes a first protective layer 11, a first thermal insulation layer 13, a first waterproof layer 14 and a second protective layer 15 stacked in sequence; a first fastener 151 is provided at one end of the second protective layer 15; the second module component 2 includes a third protective layer 21, a second thermal insulation layer 23, a second waterproof layer 24 and a fourth protective layer 25 stacked in sequence; a second fastener 251 is provided at one end of the fourth protective layer 25; the first module component 1 and the second module component 2 are spliced ​​to form a module assembly, and the first fastener 151 and the second fastener 251 are buckled.

[0042] In the above structure, the modified roof is formed by using a module assembly obtained by splicing the first module component 1 and the second module component 2, wherein the first module component 1 includes a first protective layer 11, a first thermal insulation layer 13, a first waterproof layer 14 and a second protective layer 15 stacked in sequence, and the second module component 2 includes a third protective layer 21, a second thermal insulation layer 23, a second waterproof layer 24 and a fourth protective layer 25 stacked in sequence, ensuring that the first module component 1 and the second module component 2 have structural strength, waterproof performance and thermal insulation performance that meet the requirements; and a first fastener 151 is provided at one end of the second protective layer 15, and a second fastener 251 is provided at one end of the fourth protective layer 25. After the first module component 1 and the second module component 2 are fastened by the first fastener 151 and the second fastener 251, they are spliced ​​to form a module assembly, making the connection between the first module component 1 and the second module component 2 simpler and faster. The first module component 1 and the second module component 2 can be manufactured in advance in the factory before construction, and the on-site construction personnel only need to splice the first module component 1 and the second module component 2, which can reduce the time and complexity of on-site construction, reduce the skill requirements and construction difficulty of the construction personnel; and the prefabricated first module component 1 and the second module component 2 can be quality controlled during production to ensure that each module meets the standards before arriving at the construction site, thereby ensuring the construction quality of the roof renovation; in addition, the design of the first fastener 151 and the second fastener 251 reduces the time and labor required for on-site welding or fixing, thereby shortening the construction time of the roof renovation, reducing labor costs, and improving construction efficiency.

[0043] The first protective layer 11, the first thermal insulation layer 13, the first waterproof layer 14 and the second protective layer 15 are bonded to form a stable integrated structure. By integrating thermal insulation and waterproofing, the first waterproof layer 14 and the first thermal insulation layer 13 are ensured to be tightly bonded, thereby improving the stability and durability of the overall system. Similarly, the third protective layer 21, the second thermal insulation layer 23, the second waterproof layer 24 and the fourth protective layer 25 are bonded to form a stable integrated structure, thereby ensuring the tightly bonded second waterproof layer 24 and the second thermal insulation layer 23. The prefabricated first module component 1 and the second module component 2 are easy to inspect and replace, simplifying the maintenance process and reducing long-term maintenance costs.

[0044] In one embodiment, the first fastener 151 extends in a direction away from the first thermal insulation layer 13, and the end of the first fastener 151 is bent to form a slot 1511. The second fastener 251 extends in a direction away from the second thermal insulation layer 23, and the end of the second fastener 251 is bent to form a bent section 2511, and the bent section 2511 is inserted into the slot 1511 to achieve buckling. The bent section 2511 can be directly inserted into the slot 1511 without the need for additional fixings or tools, so that the first fastener 151 and the second fastener 251 can achieve the purpose of quick connection, thereby enabling the first module component 1 and the second module component 2 to be quickly assembled and disassembled, and the first module component 1 and the second module component 2 have the advantage of convenient transportation after being disassembled; the cooperation of the bent section 2511 and the slot 1511 can ensure that the first module component 1 and the second module component 2 remain stable after splicing, and are not easily separated due to wind or other external forces. Exemplarily, the slot 1511 is a U-shaped slot, and the bending section 2511 forms a U-shaped structure, and the U-shaped structure is adapted to the U-shaped slot.

[0045] In one embodiment, a first vapor barrier 12 is further provided between the first protective layer 11 and the first thermal insulation layer 13; a second vapor barrier 22 is further provided between the second protective layer 15 and the second thermal insulation layer 23. In the first thermal insulation layer 13 or the second thermal insulation layer 23, since the temperature difference may cause condensation of water vapor, the first vapor barrier 12 and the second vapor barrier 22 can prevent water vapor from penetrating from the external environment to the first thermal insulation layer 13 or the second thermal insulation layer 23, which can reduce such condensation phenomenon, and further reduce the damage of moisture to the first module component 1 or the second module component 2, so as to protect the roof structure from moisture.

The first waterproof breathable membrane 141 and the second waterproof breathable membrane 241 allow water vapor to pass through, but can prevent the penetration of liquid water. This characteristic helps to reduce condensation under the roof while allowing moisture to be discharged. The composite waterproof layer is composed of multiple layers of materials to provide additional waterproof protection, and the composite waterproof layer can be formed of one or more materials selected from rubber, asphalt, polymer or other waterproof materials. The first waterproof breathable membrane 141 is located between the first thermal insulation layer 13 and the first composite waterproof layer 142, which can ensure that water vapor can be discharged from the first thermal insulation layer 13 to prevent external moisture from invading; similarly, the second waterproof breathable membrane 241 is located between the second thermal insulation layer 23 and the second composite waterproof layer 242, which can ensure that water vapor can be discharged from the second thermal insulation layer 23.

[0047] In one embodiment, the first waterproof breathable membrane 141 and the second waterproof breathable membrane 241 both include a laminated spunbonded polyethylene layer and a polypropylene film layer. The first waterproof breathable membrane 141 and the second waterproof breathable membrane 241 include a spunbonded polyethylene layer and a polypropylene film layer, which enhances the strength and durability of the material. Both polyethylene and polypropylene materials have good waterproof properties. The laminated structure can further improve the waterproof effect, allowing water vapor molecules to pass through while preventing liquid water from penetrating, thereby achieving the waterproof and breathable function.

[0048] In one embodiment, the first protective layer 11, the second protective layer 15, the third protective layer 21 and the fourth protective layer 25 are made of corrugated steel plates.

In addition, the surface of the aluminum-magnesium-manganese alloy steel plate is dense and smooth, not easy to absorb dust, and is as clean as new after being washed by rainwater. There will be no mottled phenomenon after dirt accumulation and being washed by rainwater, and it has good self-cleaning properties.

[0049] In one embodiment, a first fixing part 111 is provided on a side of the first protective layer 11 away from the first thermal insulation layer, and a second fixing part 211 is provided on a side of the third protective layer 21 away from the second thermal insulation layer; the first fixing part 111 and the second fixing part are used to connect with the roof purlin; it should be noted that the first module component 1 and the second module component 2 are first buckled, and then the first module component 1 and the second module component 2 are respectively fixed to the roof purlin by using screws and full-length thermal insulation gaskets; the purlin is generally made of steel, and the first protective layer 11 and the third protective layer 21 are made of aluminum-magnesium-manganese corrugated double-layer metal plates, which can avoid electrochemical reactions between the first protective layer 11 and the second protective layer 15 and the purlins, and effectively control the cold bridge effect.

[0050] In one embodiment, the first composite waterproof layer 142 and the second composite waterproof layer 242 are both made of EPT waterproof roll.

Rock wool has good thermal insulation performance, can effectively reduce the transfer of heat, keep the indoor temperature stable, and has a high melting point and good flame retardant performance, can effectively delay the spread of fire, and has good sound absorption performance to reduce noise transmission and improve the comfort of the indoor environment. Glass wool also has good thermal insulation performance, can effectively reduce energy consumption, has good fire resistance, good sound absorption performance, good aging resistance, and long service life; in addition, the glass wool material also has the advantage of light weight, which can reduce the weight of the first module component 1 and the second module component 2.

[0052] In one embodiment, the thickness of the first thermal insulation layer 13 and the second thermal insulation layer 23 ranges from 40 mm to 60 mm. Within this thickness range, the first thermal insulation layer 13 and the second thermal insulation layer 23 can provide good thermal resistance, reduce heat loss, and improve energy efficiency; the thickness of the thermal insulation material (such as rock wool or glass wool) will affect its thermal conductivity and density; within the above thickness range, the first thermal insulation layer 13 and the second thermal insulation layer 23 can provide excellent thermal insulation performance while maintaining reasonable weight and cost.

[0053] In one embodiment, the thickness of the first composite waterproof layer 142 and the second composite waterproof layer 242 ranges from 1 mm to 2 mm. The first composite waterproof layer 142 and the second composite waterproof layer 242 have a thickness of 1 mm to 2 mm, which can provide sufficient waterproof protection while maintaining the flexibility and durability of the material, making it easier to install and handle.

[0054] In one embodiment, the end of the first thermal insulation layer 13 close to the first module component 1 is indented into the first protective layer 11; the end of the first waterproof layer 14 close to the first module component 1 is indented into the first thermal insulation layer 13; the end of the second protective layer 15 close to the first module component 1 is indented into the first waterproof layer 14; the end of the second thermal insulation layer 23 close to the second module component 2 protrudes from the third protective layer 21, the first protective layer 11 and the third protective layer 21 cooperate, and the first thermal insulation layer 13 and the second thermal insulation layer 23 cooperate; the end of the second waterproof layer 24 close to the second module component 2 protrudes from the second thermal insulation layer 23, and the first waterproof layer 14 and the second waterproof layer 24 cooperate; the end of the fourth protective layer 25 close to the second module component 2 protrudes from the second waterproof layer 24, and the fourth protective layer 25 and the second protective layer 15 cooperate.
