Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall panels, and more specifically, to a prefabricated wall panel with a reinforced structure. Background Technology

[0002] Precast wall panels are prefabricated in the factory and can be directly transported to the construction site for installation. Compared with traditional on-site masonry or pouring methods, precast wall panels allow for faster construction and significantly shorten the construction period. This not only helps control the project schedule but also reduces construction costs and improves overall construction efficiency.

[0003] A search revealed that Chinese Patent Publication No. CN220725511U discloses "a precast wall panel, relating to the field of building engineering technology, aiming to solve the problem of poor sealing at the joint of precast wall panels. The key technical points are: the precast wall panel includes several wall panel units and several wall panel connectors. The wall panel connectors are located at the joints of two adjacent wall panel units. The sidewalls of the wall panel units and the wall panel connectors are interlocked. A sealing cavity is formed on the sidewall of the wall panel unit. The wall panel connectors have elastic deformation properties. The volume of the wall panel connector entering the sealing cavity is greater than the volume of the sealing cavity, forming a reinforced sealing connection structure. This improves the fit between the wall panel connectors and the wall panel units, enhances the sealing effect, avoids the protrusion of connecting components, facilitates installation, improves on-site assembly efficiency, enhances practicality, increases the durability of precast wall panel connections, and makes the connection seal more stable." However, the following defects still exist:

[0004] Precast wall panels have relatively weak overall strength and are difficult to withstand unexpected impacts during practical applications, which can easily lead to safety accidents.

[0005] Therefore, we have made improvements to this by proposing a prefabricated wall panel with a reinforced structure. Utility Model Content

[0006] The purpose of this utility model is to address the problem that the existing precast wall panels have relatively weak overall strength, making them difficult to withstand unexpected impacts during practical applications and easily causing safety accidents.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] Precast wall panels with reinforced structures are used to improve the above-mentioned problems.

[0009] The specific details of this utility model are as follows:

[0010] It includes a wall panel unit, the interior of which is provided with a composite structure to improve the strength of the wall panel unit.

[0011] The composite structure includes an elastic plate, a plate frame, a reinforcing mesh layer, a fireproof and moisture-proof layer, a microporous self-healing coating, and a decorative protective layer. The elastic plate is located in the middle of the wall panel unit, and the cross-sectional shape of the elastic plate is wavy. The plate frame is located on both sides of the elastic plate. The reinforcing mesh layer, the fireproof and moisture-proof layer, the microporous self-healing coating, and the decorative protective layer are sequentially arranged on the surface of the plate frame.

[0012] As a preferred technical solution of this utility model, the plate frame is made of high-strength, low-shrinkage concrete and is fixedly installed on both sides of the elastic plate.

[0013] As a preferred technical solution of this utility model, the reinforcing mesh layer is bonded to the surface of the plate frame by concrete.

[0014] As a preferred technical solution of this utility model, the fireproof and moisture-proof layer is made of glass wool and is located on the outside of the reinforcing grid layer and is bonded to the surface of the board frame by concrete.

[0015] As a preferred technical solution of this utility model, the microporous self-healing coating contains a microencapsulated healing agent and is located on the outside of the fireproof and moisture-proof layer.

[0016] As a preferred technical solution of this utility model, the decorative protective layer adopts a high-performance polymer coating and is disposed on the outermost side of the wall panel unit.

[0017] As a preferred technical solution of this utility model, a reinforcing plate is fixedly provided around the perimeter of the wall panel unit, and the reinforcing plate seals the perimeter of the wall panel unit.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the solution of this utility model:

[0020] Through its composite structure, the elastic panel is composed of multiple layers of materials with different elastic moduli, which can effectively disperse and absorb energy when subjected to impact, protecting the wall structure from damage. The panel frame contains steel fibers or polypropylene fibers to enhance toughness, providing the wall panel with the main load-bearing capacity and structural stability. The reinforcing mesh layer is impregnated with special resins or polymers to enhance its adhesion. The fiberglass mesh can effectively disperse and transfer stress, preventing cracks in the concrete layer. The fireproof and moisture-proof layer can effectively prevent the spread of fire, has good moisture absorption and breathability, and can prevent moisture and mold from growing inside the wall panel. The microporous self-healing coating contains a special coating with microencapsulated healing agents. When tiny cracks appear on the surface of the wall panel, the microcapsules rupture to release the healing agent, which automatically fills and repairs the cracks, thereby extending the service life of the wall panel and improving its durability.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] like Figure 1-5As shown, this embodiment proposes a prefabricated wall panel with a reinforced structure, including a wall panel unit 1, and a composite structure 2 for improving the strength of the wall panel unit 1 is provided inside the wall panel unit 1.

[0033] like Figure 5 As shown, the composite structure 2 includes an elastic plate 201, a plate frame 202, a reinforcing mesh layer 203, a fireproof and moisture-proof layer 204, a microporous self-healing coating 205, and a decorative protective layer 206. The elastic plate 201 is located in the middle of the wall panel unit 1, and the cross-sectional shape of the elastic plate 201 is wavy. The plate frame 202 is located on both sides of the elastic plate 201. The reinforcing mesh layer 203, the fireproof and moisture-proof layer 204, the microporous self-healing coating 205, and the decorative protective layer 206 are sequentially disposed on the surface of the plate frame 202. The elastic plate 201 effectively disperses and absorbs energy when subjected to impact; the plate frame 202 provides the main load-bearing capacity and structural stability of the wall panel; the reinforcing mesh layer 203 is impregnated with a special resin or polymer to enhance its adhesion; the reinforcing mesh layer 203 uses fiberglass mesh, which can effectively disperse and transfer stress and prevent cracks in the concrete layer; the fireproof and moisture-proof layer 204 can effectively prevent the spread of fire, has good moisture absorption and breathability, and can prevent the interior of the wall panel from getting damp and moldy; when micro-cracks appear on the surface of the wall panel, the microcapsules inside the microporous self-healing coating 205 rupture and release a healing agent, which automatically fills and repairs the cracks.

[0034] like Figure 5 As shown, the plate frame 202 is made of high-strength, low-shrinkage concrete and is fixedly installed on both sides of the elastic plate 201. The plate frame 202 contains steel fibers or polypropylene fibers to enhance toughness, and the addition of fibers improves the crack resistance and durability of the concrete.

[0035] like Figure 5 As shown, the reinforcing mesh layer 203 is bonded to the surface of the plate frame 202 by concrete. The reinforcing mesh layer 203 is impregnated with a special resin or polymer to enhance its adhesion, improve the bond strength between the mesh and the concrete, and enhance the integrity of the overall structure.

[0036] like Figure 5 As shown, the fireproof and moisture-proof layer 204 is made of glass wool and is located outside the reinforcing mesh layer 203, bonded to the surface of the board frame 202 by concrete. The fireproof and moisture-proof layer 204 has undergone special treatment to improve its fireproof and moisture-proof performance.

[0037] like Figure 5As shown, the microporous self-healing coating 205 contains a microencapsulated healing agent and is located on the outside of the fireproof and moisture-proof layer 204. The microporous self-healing coating 205 contains a special coating with a microencapsulated healing agent inside. When a small crack appears in the decorative protective layer 206 on the wall panel surface, part of the microporous self-healing coating 205 will be exposed to the outside. Upon contact with air, the microcapsules gradually rupture, releasing the healing agent, which is composed of dicyclopentadiene. This healing agent automatically fills and repairs the crack, thereby extending the service life of the wall panel and improving its durability.

[0038] like Figure 5 As shown, the decorative protective layer 206 is made of a high-performance polymer coating and is located on the outermost side of the wall panel unit 1. The decorative protective layer 206 contains ultraviolet absorbers and anti-aging agents, which can resist the erosion of harsh environments such as ultraviolet rays, wind and rain, and chemical corrosion.

[0039] like Figure 3 As shown, reinforcing plates 3 are fixedly installed around the perimeter of wall panel unit 1, sealing the perimeter of wall panel unit 1. This improves the overall strength and sealing performance of the wall panel.

[0040] Specifically, during operation, the precast wall panel with reinforced structure exhibits the following characteristics: the elastic plate 201 effectively disperses and absorbs energy upon impact, protecting the wall structure from damage; the panel frame 202 contains steel or polypropylene fibers to enhance toughness, and the addition of fibers improves the crack resistance and durability of the concrete; the reinforcing mesh layer 203 is impregnated with special resins or polymers to enhance its adhesion; the fireproof and moisture-proof layer 204 undergoes special treatment to improve its fireproof and moisture-proof performance; the microporous self-healing coating 205 contains a special coating with microencapsulated healing agents; when tiny cracks appear on the wall panel surface, the microcapsules rupture to release the healing agent, automatically filling and repairing the cracks, thereby extending the service life of the wall panel and improving its durability; and the decorative protective layer 206 resists the erosion of harsh environments such as ultraviolet rays, wind, rain, and chemical corrosion.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
