Description

Technical Field

[0001] This utility model relates to the field of fireproof and heat-insulating wall structure technology, specifically to a protective system that improves the fireproof and energy-saving performance of existing wall protection structures. Background Technology

[0002] With the rapid development of my country's economy and society, the number of high-rise civil buildings has increased dramatically. Due to the large size and complex functions of high-rise buildings, fire safety standards are difficult to meet, resulting in high overall fire risk. Moreover, once a fire occurs, the fire spreads rapidly due to multiple pathways and speed, further increasing safety risks. At the same time, many early buildings used combustible insulation materials as insulation structures, resulting in a large number of high-rise buildings using combustible external insulation, which poses significant fire hazards.

[0003] With increasingly stringent requirements for building energy efficiency and urban renewal, the energy efficiency and fire resistance of existing buildings also need to be improved. However, replacing the entire insulation material significantly increases costs and poses safety risks, such as insulation detachment during removal. Furthermore, it results in long construction periods and disruptions to normal building use. This invention provides a protective system that enhances the fire resistance and energy efficiency of existing wall structures, addressing these issues. Utility Model Content

[0004] This utility model provides a protective system that enhances the fire resistance and energy-saving efficiency of existing wall protection structures, improving overall fire resistance and building energy efficiency without altering the original building insulation structure.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: A protective system for improving the fire resistance and energy efficiency of existing wall protection structures includes a wall, a window, a protective structure, and an outer covering structure. The protective structure includes a wall protection structure and a window opening protection structure. The protective structure is installed on the wall, the window opening protection structure is located on the outer periphery of the window, and the outer covering structure is installed on the outside of the protective structure and connected to the wall. The wall protection structure includes an insulation layer and a fireproof wall layer. The insulation layer is located on the wall, and the fireproof wall layer is located on the outside of the insulation layer. The window opening protection structure includes a window fireproof layer, which is located on the wall surrounding the window opening.

[0006] Furthermore, the wall protection structure and the window opening protection structure have the same thickness, and the outer end face of the window opening protection structure is attached to the inner end face of the wall protection structure.

[0007] Furthermore, the outer covering structure includes a connecting layer and a decorative layer, wherein the connecting layer is disposed on the outside of the protective structure and the decorative layer is disposed on the outside of the connecting layer.

[0008] Furthermore, the outer covering structure includes a surface layer and an end face layer, wherein the surface layer is located on the outer surface of the protective structure and the end face layer is located on the inner end face of the protective structure.

[0009] Furthermore, the connecting layer includes a connecting mesh and connecting mortar, wherein the connecting mesh is disposed within the connecting mortar.

[0010] Furthermore, it also includes a connecting bolt, through which the wall protection structure is connected to the wall, with the outer end of the connecting bolt located in the outer covering structure.

[0011] Furthermore, the window opening protection structure is a U-shaped structure with a width of 100-200mm.

[0012] Furthermore, the connecting layer is provided in two layers, and the outer end of the connecting bolt is connected to the inner connecting layer.

[0013] The beneficial effects of this utility model are as follows: The insulation layer on the wall around the window opening is removed and replaced with a window opening protection structure to improve the fire resistance within the window opening area. At the same time, a fireproof layer is added to the outside of the insulation layer on the wall surface to give it fire resistance function, while also further improving the insulation performance of the wall, thereby improving the building's energy efficiency. Adding an external cladding structure not only secures the new fireproof layer but also enhances the building's aesthetics and further improves its thermal insulation performance.

[0018] like Figure 1 , 2 As shown, a protective system for improving the fire resistance and energy efficiency of existing wall protective structures includes a wall 1, a window 2, a protective structure, and an outer covering structure 3. The protective structure includes a wall protective structure 4 and a window opening protective structure 5. The protective structure is installed on the wall 1 and has heat insulation and fire resistance effects. The window opening protective structure 5 is located on the outer periphery of the window 2 and is used to improve the fire resistance effect of the protective structure. The outer covering structure 3 is installed on the outside of the protective structure and is connected to the wall 1.

[0019] This utility model is used to improve the fire resistance of existing buildings. By adding a fireproof wall layer 42 to the outside of the original insulation layer 41, the fire resistance of the building is improved. The newly added fireproof wall layer 42 also improves the insulation performance of the wall, thereby improving the building's energy-saving effect. The window opening protection structure 5 located at the window opening acts as a seal on the end face of the insulation layer 41. By using the fireproof wall layer 42 on the outside of the original insulation layer 41 and the window opening protection structure 5 on the end face of the insulation layer 41, the insulation layer 41 is completely sealed and wrapped, thereby playing an isolation role and preventing the insulation layer 41 from being ignited, and further ensuring the fire resistance of the building. An outer covering structure 3 is set on the outermost side to fix the fireproof wall layer 42 and also serves a decorative purpose.

[0020] like Figure 1 As shown, the wall protection structure 4 includes an insulation layer 41 and a wall fireproof layer 42. The insulation layer 41 is provided on the wall 1 and is the original insulation layer of the building. The wall fireproof layer 42 is provided on the outside of the insulation layer 41 to protect the outside of the insulation layer 41. The window opening protection structure 5 includes a window fireproof layer, which is provided on the wall around the window 2.

[0021] Furthermore, the wall protection structure 4 and the window opening protection structure 5 have the same thickness, that is, the thickness of the window fireproof layer is the same as the combined thickness of the insulation layer 41 and the wall fireproof layer 42, and the outer end face of the window opening protection structure 5 is in contact with the inner end face of the wall protection structure 4.

[0022] like Figure 1 As shown, the outer covering structure 3 further includes a connecting layer 31 and a decorative layer 32. The connecting layer 31 is disposed on the outside of the protective structure, and the connecting layer 31 has two layers. The decorative layer 32 is disposed on the outside of the connecting layer 31.

[0023] like Figure 1 As shown, the outer covering structure 3 further includes a surface layer and an end face layer. The surface layer is located on the outer surface of the protective structure, that is, it is set parallel to the wall. The end face layer is located on the inner end face of the protective structure and extends to the window 2. The end face layer is set perpendicular to the wall and protects the inner end face of the window opening protective structure 5.

[0024] Furthermore, the connecting layer 31 includes a connecting mesh and a connecting mortar, wherein the connecting mesh is disposed in the connecting mortar, the connecting mesh is a mesh cloth, and the connecting mortar is a plastering mortar.

[0025] Furthermore, it also includes a connecting bolt 6, through which the wall protection structure 4 is connected to the wall 1 and the fireproof layer 42 of the wall is fixed. The inner end of the connecting bolt 6 passes through the insulation layer 41 and the fireproof layer 42 of the wall and is connected to the wall 1. The outer end of the connecting bolt 6 is located in the outer covering structure 3 and between the two connecting layers 31. After the inner connecting layer 31 is constructed, the connecting bolt 6 is constructed to fix the inner connecting layer 31 and the fireproof layer 42 to the wall. Then the outer connecting layer 31 is constructed.

[0026] The connecting bolt 6 is an anchor bolt.

[0027] like Figure 1 , 2 As shown, the window opening protection structure 5 is a U-shaped structure with a width of 150mm, and the wall fireproof layer 42 has a thickness of 50mm.

[0028] Preferably, the fireproof wall layer 42 and the fireproof window layer are both made of Class A non-combustible thermal insulation material, and rock wool board, foam glass or foamed ceramic can be selected as needed. The decorative layer 32 is flexible water-resistant putty or silicone resin modified coating.

[0029] The construction method of this utility model is as follows: First, remove the insulation layer 41 on wall 1 around the window opening, with the removal area being 150mm wide around the window opening; 2. Construct window opening protection structure 5 in the removal area, and fill the window fireproof layer in the removal area by full adhesion. The thickness of the window fireproof layer is the sum of the thickness of the original insulation layer 41 and the thickness of the wall fireproof layer 42 to be constructed. Then, wrap the window opening with mesh cloth to fix the window fireproof layer. 3. Apply an interface agent to the outside of the insulation layer 41 of wall 1 and construct the fireproof layer 42 of the wall. 4. Construct the first connecting layer 31 on the outside of the fireproof layer 42 of the wall, and then install and fix the connecting bolts 6. 5. Construct the second connecting layer 31 on the outside of the fireproof layer 42 of the wall, and then construct the decorative layer 32.
