At present, the performance requirements of building envelope structures in terms of fire protection, heat insulation, waterproofing, etc. are becoming increasingly prominent, especially high-rise buildings and public buildings have more stringent requirements on the comprehensive performance of envelope structures.

[0003] However, existing building envelope technologies typically utilize a single material or simple composite structure, making it difficult to simultaneously meet multiple performance requirements, such as fire protection, thermal insulation, and waterproofing. This results in insufficient building safety and a shortened building lifespan. Therefore, those skilled in the art have provided a fireproof and thermally insulated building envelope structure to address the issues raised in the background art. Summary of the Invention

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

The SBS modified asphalt waterproof membrane and the synthetic polymer waterproof coating layer together constitute a waterproof layer, and the slope leveling layer is made of lightweight aggregate concrete.

[0009] Through the above technical scheme, in order to realize that the building envelope structure can simultaneously meet the multiple performance requirements of fire prevention, heat insulation, waterproofing, etc., the wall is connected to the roof, and the wall from the outside to the inside is composed of an alkali-resistant glass fiber mesh anti-cracking mortar layer, a lime mortar layer, an interface mortar layer, an autoclaved aerated concrete block layer and a lime cement mortar layer. In the structure of the wall, the alkali-resistant glass fiber mesh anti-cracking mortar layer can prevent the surface of the wall from cracking, and the surface treatment is completed by the lime cement mortar layer. The autoclaved aerated concrete block layer is a porous concrete made of cement, lime and silica sand as the main raw materials. It contains a large number of closed pores inside, which can effectively prevent the transfer of heat and greatly reduce the heat transfer coefficient of the wall. In addition, the material itself has a high fire resistance limit, which can effectively delay the spread of fire and achieve fire prevention. Fire and heat insulation effects, in the roof structure, the crushed stone concrete layer provides protection and drainage functions, and by setting SBS modified asphalt waterproof membrane and synthetic polymer waterproof coating layer, they can jointly constitute the roof's waterproof layer, effectively preventing rainwater from penetrating and meeting waterproofing needs. The polyurethane rigid foam plastic layer is foamed by chemical reaction with isocyanate and polyether polyol as the main raw materials. Its interior is a closed-cell structure with low thermal conductivity, which can significantly improve the thermal insulation performance of the roof. The slope layer made of lightweight aggregate concrete can form a certain slope on the roof surface, ensuring that rainwater flows quickly and smoothly to the drain outlet to avoid water accumulation on the roof, thereby realizing that this device can simultaneously meet the fire protection, heat insulation, waterproofing and other multiple performance requirements of the building envelope structure, while improving safety and extending the service life of the building.

[0028] (3) Beneficial effects

[0029] The present invention provides a fireproof and heat-insulating building enclosure structure. It has the following beneficial effects:

[0030] 1. The present invention provides a fireproof and heat-insulating building envelope structure. The autoclaved aerated concrete block layer can effectively prevent heat transfer, reduce the heat transfer coefficient of the wall, and effectively delay the spread of fire, thereby achieving fireproof and heat-insulating effects. The waterproof layer is formed by the SBS modified asphalt waterproof membrane and the synthetic polymer waterproof coating layer, which effectively prevents rainwater from penetrating.

[0031] 2. The present invention provides a fireproof and heat-insulating building enclosure structure. The temperature can be detected in real time by a temperature sensor arranged in an aluminum alloy window frame. When the temperature exceeds the set value, the corresponding motor is started to rotate the corresponding threaded rod. The connection between the pulley and the synchronous belt enables the corresponding two threaded rods to rotate synchronously, thereby enabling the slider to slide on the inner wall of the slide groove, and the corresponding connecting rod is driven to move by the slider, so that the connecting rod pulls out the sunshade cloth, so that the sunshade cloth is unfolded. At this time, the coil spring is in a compressed state. When the temperature drops, the motor reverses to release the pull on the sunshade cloth. At this time, under the action of the coil spring, the winding rod can reverse, and then the sunshade cloth is rolled up into the storage tube, so that the device can start the motor to unfold the sunshade cloth when the temperature is high, which can effectively block direct sunlight, reduce indoor temperature, and reduce energy consumption of indoor equipment.

[0032] 3.
