Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building materials, and in particular relates to a prefabricated and assembled standardized production line for producing high-thermal-resistance wall panels. Background Art
[0002] Building energy consumption accounts for a high proportion of the total social energy consumption. Improving the thermal resistance of exterior walls is an important means to reduce building energy consumption and achieve ultra-low energy consumption building design.
[0003] The thermal insulation performance of the building envelope determines the energy consumption of the building's heating and cooling processes. Common envelope materials currently on the market include brick walls, concrete walls, and lightweight wall panels, but the overall thermal resistance coefficient of these walls is low, making it difficult to meet the requirements of ultra-low energy consumption buildings. At the same time, the use of standardized components for on-site installation of wall panels can improve production and installation efficiency, reduce labor consumption, and control construction capital expenditures. Therefore, developing a prefabricated, assembled, standardized assembly line-produced wall panel with high thermal resistance is an effective way to improve the performance of ultra-low energy consumption building envelopes, reduce building energy consumption, and promote green and sustainable development of buildings.
[0004] Commonly used thermal insulation prefabricated wall types are as follows:
[0005] General sandwich insulation wall: consists of two layers of reinforced concrete base panels and a layer of insulation material sandwich layer, connected into a whole by connecting parts, with good structural performance and thermal insulation performance.
[0006] External insulation wall: consists of a reinforced concrete structure layer and an external insulation material layer. Internal insulation wall: consists of a reinforced concrete structure layer and an internal insulation material layer.
[0007] Composite insulation wall: It consists of a reinforced concrete structural layer and multiple insulation layers of different materials, fixed by adhesives or anchors, and has comprehensive thermal insulation performance and functions.
[0008] However, the current method to improve the thermal resistance performance of the enclosure structure is to fill the wall panels with insulation materials, such as polystyrene boards, rock wool boards, foam concrete and other porous solid insulation materials.
[0009] The main shortcomings of general wall panels are as follows: First, the thickness of the insulation material is limited by the wall panel structure and cannot meet the high thermal resistance requirements of ultra-low energy consumption buildings.
[0010] 2. Thick concrete sandwich walls: The thickness of concrete slabs and insulation materials is too thick, which increases the building load, reduces the utilization rate of building space, and affects the aesthetics of the building.
[0011] When the insulation layer is placed externally, its quality and construction process directly impact the structural safety, reliability, durability, and insulation effectiveness of the wallboard. Due to the physical properties of the insulation material being placed externally, it is prone to shrinkage, expansion, and deformation under the influence of factors such as temperature, humidity, and pressure. This weakens the adhesion between the insulation material and the wallboard, creating gaps and easily leading to quality issues such as hollowing and cracking, which compromise the insulation effectiveness and may even cause the insulation material to fall off, compromising the structural integrity of the wallboard.
[0012] When insulation is placed externally, due to its unstable chemical and biological properties, it is susceptible to erosion by factors such as ultraviolet rays, oxidation, and microorganisms over long-term use. This can lead to aging, corrosion, and decomposition, reducing its performance and shortening its service life. Insulation materials also have poor durability and fire resistance, and are prone to aging, deformation, and combustion, impacting the service life and safety of the wallboard. Furthermore, insulation materials have poor fire resistance, and most are flammable or difficult to burn. In the event of a fire, the insulation will not only fail to block the fire, but will actually exacerbate its spread and even produce toxic and harmful smoke, endangering personnel safety.
[0013] When the insulation material layer is built in, hot and cold bridges are easily formed at the joints; the insulation layer is easily damaged by humans and the design effect cannot be achieved; the wall panel size is not universal, there are many types of production molds, and the economy is not high.
