A passive house wall panel with high impact resistance

Abstract

This utility model discloses a passive house wall panel with strong impact resistance, comprising multiple wall panel bodies. Each wall panel body includes an inner structural layer, an insulation layer, a buffer layer, and a protective outer layer, which are stacked sequentially from the inside to the outside. Double-clamping structures are provided on both sides of each wall panel body, with the double-clamping structures between two wall panel bodies engaging with each other. Through the design of the inner structural layer, insulation layer, buffer layer, and protective outer layer, when the wall panel body is subjected to external impact, the protective outer layer first disperses the impact force, followed by elastic deformation of the buffer layer to absorb and buffer the remaining impact energy, protecting the internal insulation layer and inner structural layer from damage. This greatly enhances the impact resistance of the wall panel, avoids problems such as insulation layer exposure, moisture absorption, or damage due to surface damage, and ensures the long-term stability and continuity of the passive house wall's thermal insulation performance.

Description

Technical Field

[0001] This utility model relates to the field of passive house wall panel technology, specifically to a passive house wall panel with strong impact resistance. Background Technology

[0002] A passive house is a building that provides a comfortable indoor environment without relying on traditional heating and air conditioning systems, through a highly insulated, airtight building structure and the use of renewable energy. Wall panels, as a key component of the passive house envelope, are required to possess extremely high thermal insulation and airtightness.

[0003] Currently, the external wall insulation systems commonly used in passive houses are mostly prefabricated sandwich insulation wall panels. Although these wall panels have excellent insulation performance, their exterior is usually made of ordinary concrete or a decorative layer, which generally has poor impact resistance. During use, they are easily damaged by bumps or impacts from hard objects, resulting in surface damage and cracking of the insulation layer. This not only affects the aesthetics but also seriously damages the airtightness and insulation continuity of the wall. There is an urgent need to design a passive house wall panel with strong impact resistance to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a passive house wall panel with strong impact resistance to overcome the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A passive house wall panel with strong impact resistance includes multiple wall panel bodies. Each wall panel body includes an inner structural layer, an insulation layer, a buffer layer, and a protective outer layer. The inner structural layer, insulation layer, buffer layer, and protective outer layer are stacked sequentially from the inside to the outside.

[0007] Both sides of the wall panel body are provided with double snap-fit ​​structures, and the double snap-fit ​​structures between the two wall panel bodies are interlocked. Both sides of the wall panel body are provided with filling cavities, and the two filling cavities between the two wall panel bodies are connected. Multiple threaded cylinders are provided in the top and bottom of the wall panel body.

[0008] Furthermore, the inner structural layer is made of lightweight concrete, the insulation layer is made of graphite molded polystyrene board, the buffer layer is made of rubber particle modified asphalt material, and the protective outer layer is made of high-strength polymer mortar.

[0009] Furthermore, the wall panel body has beveled surfaces on both sides, and the double-clamping structure includes two tenons and two mortises on one side of the wall panel body. The two tenons are located at the top and bottom of the filling cavity and are symmetrically distributed, and the two mortises are located at the top and bottom of the filling cavity and are symmetrically distributed. The tenons and mortises on both sides of the wall panel body are staggered.

[0010] Furthermore, the top and bottom of the filling cavity are provided with injection holes, and the tenon is provided with a through hole that communicates with the injection holes.

[0011] Furthermore, the threaded cylinder is threaded with a fixing bolt, and a lifting nut is provided on the top of the wall panel body, the lifting nut being threadedly engaged with the fixing bolt.

[0012] Furthermore, a connecting steel channel is provided at the bottom of the wall panel body, and multiple mounting bolts that are threadedly engaged with the multiple threaded cylinders are provided in the connecting steel channel.

[0013] In the above technical solution, the passive house wall panel with strong impact resistance provided by this utility model has the following beneficial effects:

[0014] By incorporating an inner structural layer, an insulation layer, a buffer layer, and a protective outer layer, when the wall panel is subjected to external impact, the protective outer layer first disperses the impact force, followed by the buffer layer undergoing elastic deformation to absorb and buffer the remaining impact energy, protecting the internal insulation layer and inner structural layer from damage. This greatly enhances the wall panel's impact resistance and avoids problems such as insulation layer exposure, moisture absorption, or damage caused by surface breakage. It ensures the long-term stability and continuity of the passive house's thermal insulation performance. The double-clamping structure allows for diagonal and horizontal connections between two wall panels, and the filling cavity is sealed and fixed with adhesive. This enables precise installation while improving construction efficiency. The airtightness between the wall panels is good, meeting the stringent requirements of passive houses.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown in the figure, this utility model provides a passive house wall panel with strong impact resistance.

[0024] It includes multiple wall panel bodies 1. Each wall panel body 1 includes an inner structural layer 2, an insulation layer 3, a buffer layer 4, and a protective outer layer 5. The inner structural layer 2, the insulation layer 3, the buffer layer 4, and the protective outer layer 5 are stacked sequentially from the inside to the outside.

[0025] Both sides of the wall panel body 1 are provided with double snap-fit ​​structures 6, and the double snap-fit ​​structures 6 between the two wall panel bodies 1 are snap-fitted together. Both sides of the wall panel body 1 are provided with filling cavities 7, and the two filling cavities 7 between the two wall panel bodies 1 are connected. Multiple threaded cylinders 8 are provided in the top and bottom of the wall panel body 1.

[0026] Reference Figure 5In this embodiment, the inner structural layer 2 is made of lightweight concrete, the insulation layer 3 is made of graphite molded polystyrene board, the buffer layer 4 is made of rubber-modified asphalt material, and the protective outer layer 5 is made of high-strength polymer mortar. The closed-cell foam plastic board, made by adding modifiers such as graphite, has excellent thermal insulation, fire resistance, weather resistance, and moisture resistance, and is mainly used for building exterior walls, roofs, and interior walls. The rubber-modified asphalt effectively prevents water penetration by increasing the adhesion and sealing properties of the asphalt. Its high viscosity makes the waterproof layer denser, and combined with the elastic structure of the rubber particles, it can resist cracks caused by vibration or deformation. The high-strength polymer mortar penetrates micro-cracks and forms a strong bond, significantly improving the overall strength and crack resistance of the wall panel and effectively preventing structural damage caused by environmental erosion or design defects.

[0027] Reference Figure 2 , Figure 3 In this embodiment, the wall panel body 1 has beveled surfaces on both sides. The double-locking structure 6 includes two tenons 9 and two mortises 10 on one side of the wall panel body 1. The two tenons 9 are located at the top and bottom of the filling cavity 7 and are symmetrically distributed. The two mortises 10 are located at the top and bottom of the filling cavity 7 and are symmetrically distributed. The tenons 9 and mortises 10 on both sides of the wall panel body 1 are staggered. Through the tenons 9, the two tenons 9 on one side of the wall panel body 1 can be inserted into the two mortises 10 on the other side of the wall panel body 1 for locking, so that the beveled surfaces between the two wall panel bodies 1 fit together. Different wall panel bodies 1 can be configured as needed, so that multiple wall panel bodies 1 can be diagonally spliced ​​and horizontally spliced.

[0028] Reference Figure 2 , Figure 3 In this embodiment, the filling cavity 7 has injection holes 11 at both the top and bottom, and the tenon 9 has a through hole 12 that communicates with the injection holes 11. Through the injection holes 11, filler adhesive can be added to the injection holes 11, allowing the filler adhesive to enter the filling cavity 7 through the injection holes 11. After filling, an rivet can be inserted into the injection holes 11, allowing the rivet to pass through the injection holes 11 and enter the through hole 12 for fixation.

[0029] Reference Figure 4 In this embodiment, the threaded cylinder 8 is internally threaded with a fixing bolt 13, and a lifting nut 14 is provided on the top of the wall panel body 1. The lifting nut 14 is threadedly engaged with the fixing bolt 13. The lifting nut 14 can be installed through the fixing bolt 13, and external equipment can be used to connect the lifting nut 14 to lift the wall panel body 1.

[0030] Reference Figure 4In this embodiment, the bottom of the wall panel body 1 is provided with a connecting steel channel 15, and multiple mounting bolts 16 that are threadedly engaged with multiple threaded cylinders 8 are provided in the connecting steel channel 15. Through the provided connecting steel channel 15, the connecting steel channel 15 can be added by the mounting bolts 16, so that the wall panel body 1 can be installed and fixed by adding the connecting steel channel 15.

[0031] Working principle: In use, the wall panel body 1 can first be hoisted and moved to a suitable position by installing the hoisting nut 14. The connecting steel channel 15 is installed at the bottom of the wall panel body 1 for fixation. After fixing the bottom position, multiple wall panel bodies 1 can be spliced ​​as needed. The opposite sides of two wall panel bodies 1 can be joined together, and diagonal splicing and horizontal splicing can be performed as needed. After splicing, the double snap-fit ​​structure 6 will snap and fix each other, connecting the two wall panel bodies 1. Then, filler adhesive is injected into the filling cavity 7 between the two wall panel bodies 1, so that the adhesive fills and connects in the filling cavity 7, sealing the connection between the two wall panel bodies 1. After the splicing and installation are completed, the protective outer layer 5 faces outward for protection and impact resistance.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
