Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a lightweight and high-strength composite wall structure for building construction. Background Technology

[0002] Buildings refer to the collective term for buildings and their ancillary facilities constructed through a series of engineering activities such as planning, design, and construction, for various purposes such as human habitation, work, study, and entertainment.

[0003] Lightweight and high-strength composite wall structures for buildings refer to wall structures made of a variety of lightweight materials that combine light weight and high strength, and are used in building construction for partitioning and enclosure.

[0004] Traditional wall insulation has limited thermal insulation performance, resulting in rapid heat loss in winter and easy entry of high outdoor temperatures into the room in summer, leading to high energy consumption for air conditioning and heating. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a lightweight and high-strength composite wall structure for building construction.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The lightweight and high-strength composite wall structure for building construction described in this utility model includes a cement layer, and a first honeycomb cavity frame is provided inside the cement layer. The first honeycomb cavity frame includes a honeycomb cavity frame composed of magnesium alloy honeycomb plate and glass fiber reinforced plastic. A polyurethane foam insulation cover plate is fixedly connected to the upper part of the inner wall of the honeycomb cavity frame, and a glass fiber reinforced plastic load-bearing support plate is fixedly connected to the lower part of the inner wall of the honeycomb cavity frame.

[0007] Preferably, the inner side of the polyurethane foam insulation cover and the glass fiber reinforced plastic load-bearing support plate is filled with a layer of glass wool.

[0008] Preferably, the inner side of the glass wool layer is filled with a composite energy storage material consisting of a mixture of wax and expanded graphite in a specific mass ratio.

[0009] Preferably, a glass fiber mesh is fixedly connected to the outside of the honeycomb cavity frame.

[0010] Preferably, the glass fiber mesh completely covers the surface of the honeycomb cavity frame.

[0011] Preferably, the outer surface of the glass fiber mesh is coated with a polymer mortar layer.

[0012] Preferably, a cement layer is fixedly connected to the outer wall of the polymer mortar layer.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The lightweight, high-strength composite wall structure for building construction described in this utility model achieves dynamic heat regulation by filling a composite energy storage material containing paraffin and expanded graphite: in winter, it absorbs and stores environmental heat such as solar radiation heat, and releases it at night to maintain indoor temperature; in summer, it absorbs excess indoor heat to prevent a sudden rise in room temperature. Combined with the heat insulation effect of the outer layer of glass fiber mesh and polymer mortar layer, it can reduce building energy consumption by more than 40%. Moreover, the composite wall uses a honeycomb cavity frame composed of magnesium alloy honeycomb panels and glass fiber reinforced plastic as its skeleton. The material has low density and high strength, which significantly reduces the self-weight of the wall by more than 30% compared with traditional walls of the same volume, thereby reducing the foundation load and improving the stability of the building structure.

[0015] 2. The lightweight, high-strength composite wall structure for building construction described in this utility model uses a glass fiber reinforced plastic (GFRP) load-bearing plate installed at the bottom of the composite energy storage material. This plate can support the weight of the energy storage material and prevent deformation of the frame bottom. It is corrosion-resistant and weather-resistant, compatible with frame materials, and securely installed. A polyurethane foam insulation cover plate covers the top of the composite energy storage material, reducing heat exchange and improving energy storage efficiency. It can seal and protect the interior of the cavity and also buffer external pressure. A glass wool layer fills the gap between the composite energy storage material, the polyurethane foam insulation cover plate, and the GFRP load-bearing plate, assisting in heat insulation, absorbing stress and impact to protect the material bag, and simultaneously filling and sealing the gaps, while also providing some sound insulation.

Combined with the heat insulation effect of the outer glass fiber mesh cloth 2 and polymer mortar layer 3, it can reduce building energy consumption by more than 40%. Moreover, the composite wall uses the honeycomb cavity frame 11 composed of magnesium alloy honeycomb panels and glass fiber reinforced plastic as the skeleton. The material has low density and high strength, which greatly reduces the self-weight of the wall by more than 30% compared with traditional walls of the same volume, which can reduce the foundation load and improve the structural stability of the building.

The polyurethane foam insulation cover plate 12 covers the top of the composite energy storage material 15, reducing heat exchange to improve energy storage efficiency. It can seal and protect the inside of the cavity and also buffer external pressure. The glass wool layer 14 fills the gap between the composite energy storage material 15, the polyurethane foam insulation cover plate 12 and the glass fiber reinforced plastic load-bearing support plate 13, which helps to insulate and absorb stress and impact to protect the material bag. At the same time, it fills and seals the gap and also has a certain sound insulation effect.

The fiberglass mesh 2 completely covers the surface of the honeycomb cavity frame 11. A polymer mortar layer 3 is coated on the outer surface of the fiberglass mesh 2. A cement layer 4 is fixedly connected to the outer wall of the polymer mortar layer 3.

Combined with the heat insulation effect of the outer glass fiber mesh cloth 2 and polymer mortar layer 3, it can reduce building energy consumption by more than 40%. Moreover, the composite wall uses the honeycomb cavity frame 11 composed of magnesium alloy honeycomb panels and glass fiber reinforced plastic as the skeleton. The material has low density and high strength, which greatly reduces the self-weight of the wall by more than 30% compared with traditional walls of the same volume, which can reduce the foundation load and improve the stability of the building structure.

[0029] The glass fiber reinforced plastic load-bearing support plate 13 is installed at the bottom of the composite energy storage material 15, which can bear the weight of the energy storage material and prevent the bottom of the frame from deforming. It is corrosion-resistant and weather-resistant, compatible with the frame material and installed firmly.
