Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation exterior wall panels, in particular to a steel keel thermal insulation decorative sandwich panel exterior wall system. Background Art

[0002] External wall panels are panels used for building exterior walls, and are suitable for a variety of building types, including high-rise buildings, industrial plants, shopping malls, hotels, etc. External wall panels can be installed in a variety of ways, either by gluing and anchoring them on the exterior walls of buildings, or by dry hanging them on the main structure.

[0003] Traditional exterior wall panels generally have the following forms: The first type: using inorganic lightweight wall panels (such as autoclaved concrete panels) alone as the outer protective components of the wall. For example, a new type of autoclaved aerated concrete panel is disclosed in the patent document with patent application number CN202022299619.0. It is usually necessary to install insulation materials on the wall on site, and the operation and construction are relatively cumbersome.

[0004] The second type: the exterior wall panels are reinforced with steel bars or steel wire mesh, and the outer side is added with a thermal insulation decorative layer. The wall panels themselves are produced by the cast-in-place reverse-beating process, and the finishing layer needs to be protected during the cast-in-place process. The wall panels are prone to cracks and need to be maintained.

[0005] The third type: cast-in-place lightweight filling materials inside the steel frame, and an additional insulation decorative layer on the outside. The wall panels also use cast-in-place technology, and there are also problems with the protection and maintenance of the finishing layer.

[0006] In summary, it can be seen that various types of exterior wall panels in the prior art still have certain shortcomings in use and construction. Based on this, the present invention optimizes and improves the problems existing in the prior art, and hereby proposes a steel keel insulation decorative sandwich panel exterior wall system to better solve the problems existing in the prior art. Summary of the invention

[0007] The present invention solves one of the above technical problems, and the technical solution adopted is: a steel keel thermal insulation decorative sandwich panel exterior wall system, comprising a plurality of prefabricated thermal insulation decorative sandwich panels that are butt-jointed, the prefabricated thermal insulation decorative sandwich panels being prefabricated parts formed by integrated composite molding; the prefabricated thermal insulation decorative sandwich panels are arranged with outdoor decorative panels, thermal insulation materials, and indoor sound insulation panels in sequence from the inside to the outside; steel keels are respectively embedded in the vertical positions close to both sides of the prefabricated thermal insulation decorative sandwich panels formed by integrated composite molding, and each steel keel is respectively connected to the prefabricated outdoor decorative panels and indoor sound insulation panels in the prefabricated thermal insulation decorative sandwich panels through the connecting components at the corresponding positions thereof, and the upper and lower ends of each of the steel keels are fixedly connected to the structural beams, concrete walls, and concrete slabs of the main structure through the adapters fixed at the ends thereof through anchor bolts.

The heat-insulating material is sandwiched in the middle and is compounded in the factory or on the construction site by organic or inorganic glue. The thickness of the heat-insulating material is determined by energy-saving calculations; the thickness of the sound-insulating panel is determined by calculations, and the sound-insulating performance of the outdoor decorative panels and decorative materials should be considered during the calculation; the surface of the sound-insulating panel can be decorated with paint, wallpaper, metal plates, etc.

[0010] In any of the above solutions, preferably, a heat-insulating material is composite-molded between the outdoor decorative panel and the indoor sound insulation board.

[0011] In any of the above solutions, it is preferred that the connection component adopts a back bolt, an L-shaped or T-shaped hanger.

[0012] During actual installation and construction, which connection component to use depends on the material selection and thickness of the decorative panel.

[0013] In any of the above solutions, it is preferred that the decorative board material used for the outdoor decorative panel includes but is not limited to cement board, granite board and metal board.

[0014] The thickness of the exterior decorative panels is determined based on structural calculations.
