Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a prefabricated concrete trough-shaped plate external wall panel. Background Art

[0002] Traditional precast concrete exterior walls include the following types:

[0003] Fully precast walls: Fully precast walls are prefabricated throughout the entire wall thickness. This approach typically reserves cast-in-place sections for connection, requiring plastering and external scaffolding. External decoration and insulation can be integrated into the precast components at the factory. Fully precast walls are typically 200mm thick and weigh between 3 and 5 tons. Fully precast walls require disassembly based on the building and structural layout, resulting in a low degree of standardization.

[0004] Prefabricated sandwich insulation exterior wall formwork: The exterior uses exterior wall panels as the formwork, while a sandwich insulation layer is prefabricated in the middle, along with the exterior wall panels. Stainless steel connectors or FRP (Fiber Reinforced Polymer / Plastics) connectors are reserved and cast together with the cast-in-place concrete of the inner wall panels to form a single unit. This wall structure offers excellent thermal insulation and effectively reduces building energy consumption. This approach addresses the problems of exterior insulation peeling and cracking. Prefabricated sandwich insulation walls reduce the amount of plastering required on the exterior walls, but this does not reduce the amount of plastering required on the interior walls. Exterior decoration can be integrated with prefabricated components in the factory, but it is not possible to prefabricate interior decoration and exterior cladding. The prefabricated portion of a prefabricated sandwich insulation exterior wall formwork is generally at least 130 mm thick, and the total wall thickness, including the cast-in-place section, is generally at least 330 mm. Prefabricated sandwich insulation exterior wall formwork must be disassembled according to the building's exterior shape, resulting in a low level of standardization.

[0005] Prefabricated sandwich insulation walls: Based on prefabricated sandwich insulation exterior wall forms, the inner panels are also prefabricated along with the outer panels. This saves on plastering. However, this approach still leaves some inner panels uncast, requiring additional plastering, and the interior walls require a separate decorative finish. While exterior decoration can be integrated by reverse-casting onto prefabricated components in the factory, it is not possible to prefabricate interior decoration integrated with the exterior envelope. Prefabricated sandwich insulation walls are generally at least 250mm thick, and prefabricated sandwich insulation exterior wall forms need to be disassembled according to the building's appearance, resulting in a low level of standardization.

[0006] Double-skin composite wall: Double-skin composite wall is a prefabricated building structural system, which is composed of two prefabricated concrete slabs (panels) and an intermediate cast-in-place concrete layer. This wall structure combines the high efficiency of prefabricated concrete and the flexibility and structural performance of cast-in-place concrete. It consists of double-skin prefabricated panels, usually made of reinforced concrete, and an intermediate cast-in-place concrete layer. The two prefabricated panels are precast in the factory with smooth surfaces and with steel bars protruding for connection with the intermediate cast-in-place concrete layer. The intermediate cast-in-place concrete layer is cast in place between the two prefabricated panels, forming the core part of the wall. After the prefabricated panels are transported to the construction site, they are installed in place using lifting equipment. The connection between the panels is usually achieved through pre-embedded connectors or protruding steel bars. After installation, concrete is poured between the two prefabricated panels to form a complete wall structure. The double-skin composite wall can achieve plaster-free precast position on the inside and outside, but because of the presence of the cast-in-place strip, some positions still need to be plastered. The exterior decoration can be achieved by reverse punching on the prefabricated components in the factory, achieving decoration integration, but it cannot integrate interior decoration with the exterior enclosure for prefabrication. The prefabricated thickness of the double-skin composite wall is generally 120mm, and the total thickness of the wall with the cavity is more than 200mm.

[0007] Standardized panels: Standardized panels are produced according to certain national standards, industry standards or enterprise standards, with uniform size, shape and performance. For example, autoclaved aerated concrete panels are porous lightweight silicate prefabricated panels, commonly known as AAC panels, which are made of siliceous and calcareous materials as the main raw materials, mixed with gas-forming agents and other adjusting materials, and configured with rust-proof treated steel mesh cages or steel mesh sheets. Through processes such as batching, pouring, gas-forming and static stopping, cutting and autoclave curing, etc. This type of wall panel has the characteristics of lightweight, thermal insulation, fireproofing, sound absorption, etc., and is widely used in the interior and exterior wall partitions, thermal insulation layers and other parts of buildings. Autoclaved aerated concrete exterior wall panels, exterior finishes, connection nodes and related supporting materials are composed, placed on the outer periphery of the main building structure, and are a non-load-bearing enclosure system that integrates decoration, thermal insulation, fireproofing, sound insulation and waterproofing, commonly known as AAC exterior wall panel system. After using the autoclaved aerated concrete panel system, interior and exterior decoration still needs to be installed after the installation of the autoclaved aerated concrete panel. Because it is a finished panel, it can achieve thin plastering on the surface (some high-quality finished products can be plaster-free), but it cannot achieve the integration of decoration, thermal insulation and finished panel. The thickness of the standardized panel used for exterior enclosure is generally 200mm-250mm. It is relatively difficult to achieve the purpose of reusability.

[0008] In summary, the common shortcomings of the existing prefabricated outer wall are large thickness, large self-weight, poor standardization and universality, and it is difficult for the prefabricated wallboard to simultaneously realize lightweight, modularization and reconfiguration, and it is difficult to play the advantages of factory production of prefabricated components. Therefore, it is necessary to provide a prefabricated concrete trough-shaped plate external wall panel, which can solve the problem that the prefabricated wallboard is difficult to simultaneously realize lightweight, modularization and reconfiguration in the prior art.
