Description

Technical Field

[0001] This application pertains to the field of building construction, specifically to the steel structure perforated metal plate thermal insulation, waterproofing, and vapor barrier curtain wall for waste incineration power plants. Background Technology

[0002] With economic development, accelerated urbanization, and improved living standards, the amount of urban household waste is increasing. Faced with the increasingly severe situation of "garbage surrounding cities," waste-to-energy incineration has developed rapidly in recent years as the best way to dispose of household waste in a "reduced, harmless, and resource-oriented" manner.

[0003] The development of waste-to-energy incineration buildings has led to increasing demands for de-industrialization of factory buildings, and requirements have begun to emerge for the use of perforated panels for various architectural designs on the exterior surfaces of buildings.

[0004] In addition to biogas, the fermentation process of garbage in the garbage pit also produces large amounts of H2S and NH3. 3 The garbage dump will emit foul odors. To prevent these odors from escaping into the surrounding environment, the garbage dump must be kept under negative pressure. This will produce a small amount of irritating odor, necessitating gas isolation of the building. Industrial plants in cold regions require insulation treatment according to the "Code for Energy Conservation and Renewable Energy Utilization in Buildings" (GB 55015-2021) and external wall waterproofing treatment according to the "General Code for Waterproofing of Buildings and Municipal Engineering" (GB55030-2022). Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure perforated metal plate thermal insulation, waterproof and vapor barrier curtain wall for waste incineration power plants, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel perforated metal panel thermal insulation, waterproof, and vapor barrier curtain wall for a waste incineration power plant, characterized in that: it includes a keel frame, a decorative layer and a waterproof layer on the outer side, and a thermal insulation and vapor barrier layer on the inner side. The decorative layer includes corrugated aluminum plates and H-shaped aluminum alloy bases, and several of the H-shaped aluminum alloy bases are snapped onto the main and secondary keels of the keel frame and fixed by bolt groups. The thermal insulation and vapor barrier layer includes thermal insulation rock wool disposed between the main keels and inside the secondary keels, a waterproof and breathable membrane laid on the inner wall of the thermal insulation rock wool, and inner steel plate pressure strips distributed inside the thermal insulation rock wool and outer steel plate pressure strips distributed outside the waterproof and breathable membrane.

[0008] More preferably, the inner and outer steel plate clamping strips are fixed to the main keels on both sides by their folded edges, forming a limit on the waterproof and breathable membrane 7 and the thermal insulation rock wool.

[0009] Furthermore, the H-shaped aluminum alloy base includes an H-shaped body and extended edges on both sides of the H-shaped body. The upper and lower openings of the H-shaped body are distributed for engaging with the keel and fixing the end folded edges of the corrugated aluminum plate.

[0010] Furthermore, the keel frame includes a main keel made of 120*60*4mm galvanized rectangular steel pipe and a secondary keel made of 50*50*5mm galvanized rectangular steel pipe, wherein the secondary keel is flush with the outer surface of the main keel.

[0011] Furthermore, the waterproof and breathable membrane is 0.5 mm thick, and the thermal insulation rock wool is 50 mm thick.

[0012] Furthermore, the waterproof layer is a 1.2mm fluorocarbon-coated waterproof steel plate, which is fixed to the edge of the H-shaped aluminum alloy base by screws.

[0013] In addition, a 0.5mm thick hot-dip galvanized profiled steel sheet is laid on the outside of the inner steel plate compression strip to form a protective layer.

[0014] More preferably, the H-shaped aluminum alloy base is used to seal the opening of the corrugated aluminum plate with silicone weather-resistant sealant.

[0015] Compared with the prior art, this utility model has the following features and beneficial effects:

[0016] To address the problem that existing incinerator exterior walls, designed using perforated panels during the deindustrialization process, often lack proper sealing, leading to internal gas leakage and environmental pollution, as well as rainwater intrusion, this application provides a prefabricated perforated metal panel curtain wall device that provides air isolation, insulation, and waterproofing. This achieves complete isolation of the plant's side walls from external gases, temperatures, and rainwater.

[0017] Compared to the existing curtain wall design of steel structure exterior walls with perforated panels in waste incineration power plants, this application uses 50mm thick thermal insulation rock wool and 0.5mm thick waterproof and breathable membrane, with 1.5mm thick 30mm hot-dip galvanized steel plates on both sides for extrusion fixation. The insulation layer, vapor barrier layer, inner 0.5mm thick hot-dip galvanized profiled steel plate (with PE paint finish), middle 1.2mm fluorocarbon sprayed waterproof steel plate, and outer 3mm perforated corrugated aluminum plate are uniformly fixed by M8 stainless steel bolts, H-type aluminum alloy fixing bases, and keel frame. The outer gaps are sealed with silicone weather-resistant sealant. While ensuring the architectural aesthetics, the prefabricated method achieves a unified effect of safety, vapor barrier, thermal insulation, and waterproofing. Attached Figure Description
