Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior wall panels, and specifically relates to a polyphenyl particle active powder concrete heat bridge-free truss wall panel. Background Art

[0002] In the existing technology, building industrialization, housing industrialization and urbanization construction require the active promotion of prefabricated construction. In the building envelope structure, the key indicator for assessing the level of building industrialization is the degree of assembly of the exterior wall.

[0003] Good thermal insulation performance of building walls is the core of achieving building energy conservation. Integrating wall insulation and structure, ensuring the insulation has the same lifespan as the building, and promoting the innovation of new wall materials and the pace of building energy conservation are not only major innovations in traditional building design and construction methods, but also meet the needs of building energy conservation development, and meet the needs of continuously improving building standardization, factory production of components, mechanized construction and efficient management, improving labor productivity, reducing project costs, improving project quality, and achieving sustainable development of green buildings.

[0004] At present, the main types of wall panels that can be used as prefabricated exterior wall panels in China are: load-bearing concrete rock wool composite exterior wall panels, thin-walled concrete rock wool composite exterior wall panels, concrete polystyrene composite exterior wall panels, concrete perlite composite exterior wall panels, wire mesh cement insulation material sandwich panels, SP prestressed hollow panels, aerated concrete exterior wall strips and vacuum extruded fiber cement boards.

[0005] The prefabricated exterior walls mainly used in the existing technology market are mostly used for PC prefabricated buildings. Most sandwich composite wall panels use ordinary concrete as the structural layer, use thermal insulation materials sandwiched in the wall or use lightweight concrete as the surface layer. There are also integral special materials such as aerated concrete, cement wood wool board, etc. used as exterior walls to achieve the corresponding strength, lightness and thermal insulation requirements. Sandwich composite wall panels use ordinary concrete as the structural layer. The prefabricated PC concrete wall in the existing technology has the disadvantages of large overall weight, inconvenient hoisting, high surface density, low installation efficiency, and the presence of thermal bridges, which reduces the thermal insulation performance. In addition, the new material wall also has the disadvantages of high cost, low material penetration rate and limited production. Utility Model Content

[0009] The following is a further optimization of the above technical solution by the utility model:

[0010] The inner plate is made of polystyrene particle lightweight aggregate active powder concrete, and the thickness of the inner plate is 50 mm.

[0011] Further optimization: the steel mesh is made of high-ductility cold-rolled ribbed steel bars that are arranged in a criss-cross pattern, and the steel mesh is integrally cast in the inner plate.

[0012] Further optimization: the diameter of the high-ductility cold-rolled ribbed steel bar is φ6mm, the steel mesh is a mesh structure, and the mesh size of the steel mesh is 150mm*150mm.

[0013] Further optimization: the C-shaped steel ribs include thin-walled C-shaped steels fixedly mounted on one side of the outer wall panel opposite to the inner panel, and the thin-walled C-shaped steels are arranged along the length direction of the outer wall panel.

[0014] Further optimization: a second insulating concrete layer is arranged inside the thin-walled C-shaped steel.

[0015] Further optimization: the reinforcement component includes a three-legged steel truss, which is arranged in parallel with the thin-walled C-shaped steel. One end of the three-legged steel truss is integrally cast in the second insulating concrete layer, and the other end of the three-legged steel truss is gripped and anchored with a steel mesh.

It can reduce the thermal bridge effect in the application of wall panels in the construction industry and further improve the thermal insulation performance of the wall panels. At the same time, it adopts the material of polystyrene particle light aggregate active powder concrete to make the wall panels lighter, easy to install, and increase the scope of use. It is convenient to use, safe and reliable, easy to operate, and the overall structure is simple, easy to manufacture and produce, which can reduce production and use costs and improve economic benefits.

[0032] The diameter of the high-ductility cold-rolled ribbed steel bar is φ6 mm, the steel mesh 11 is a mesh structure, and the mesh size of the steel mesh 11 is 150 mm*150 mm.

[0033] The exterior wall panels 2 are made of materials commonly used in the construction field for decorative exterior wall panels. The exterior wall panels 2 are selected and matched according to the architectural design style and the use environment. The specific material composition is well known in the prior art and will not be described in detail here.

[0034] The C-shaped steel rib 3 comprises a thin-walled C-shaped steel 31 fixedly mounted on a surface of the outer wall panel 2 opposite to the inner panel 1 .
