Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a prefabricated cement-based exterior wall panel with integrated exterior window auxiliary frames. Background Art

[0002] The exterior wall of a building is an important part of the building. Its main functions include bearing a certain load, shielding against wind and rain, heat insulation, noise prevention and fire safety. From an architectural point of view, the exterior wall is a component that surrounds the building and forms a boundary between indoor and outdoor.

[0003] In the exterior wall of a building, the auxiliary frame is a transition system connecting the window system and the exterior wall. The connection method between the auxiliary frame and the exterior wall will directly affect the safety, waterproofing and thermal insulation performance of the exterior wall.

[0004] Existing attachment frames are usually installed after the construction of the building's exterior wall is completed (post-installation method). This type of attachment frame needs to be prefabricated in the factory, which is prone to deformation during subsequent transportation, storage and installation. After installation, there is a greater risk of falling off, resulting in an increase in large-scale repair work on the construction site, reducing construction efficiency, and also damaging the integrity of the attachment frame. At the same time, in the post-installation method, the attachment frame has poor adhesion to the exterior wall. When the temperature difference between indoor and outdoor is large, the two materials have different expansion and contraction characteristics, which can easily lead to cracks at the connection between the two, resulting in gaps, which greatly reduces the airtightness and forms water leakage points, causing the durability of the wall to decrease.

[0005] Therefore, the traditional window hole frame structure and installation method are insufficient in waterproof performance. Rainwater can easily penetrate into the wall through the gap between the frame and the window hole, causing wall leakage, mold and other problems. This not only affects the beauty of the building, but also reduces the durability and thermal insulation performance of the building. At present, some solutions use sealants to fill the gaps, but sealants are prone to aging and cracking during long-term use, thus losing their waterproof effect.

[0006] Based on the above technical problems, there is a need for a prefabricated cement-based exterior wall panel with integrated exterior window auxiliary frames. The exterior wall panel is integrated with auxiliary frames, which helps to improve the integrity of the exterior wall enclosure system, thereby improving the durability, waterproofness and thermal insulation performance of the exterior wall enclosure system.

[0043] This embodiment provides a prefabricated cement-based exterior wall panel with integrated exterior window auxiliary frame, comprising: a wall body 10, an auxiliary frame 20 and a window frame 30;

[0044] The wall 10 is provided with a window hole 11 , and the auxiliary frame 20 is arranged in the window hole 11 .

[0045] The auxiliary frame 20 includes a frame 21 and a functional structural member 22 ; at least the outer wall portion of the frame 21 is buried in the wall 10 .

[0046] Please refer to Figure 1 and Figure 2 As shown, during the manufacturing process, a mold 40 is required. The mold 40 includes an outer frame 41 and an inner frame 42. The inner frame 42 is located inside the outer frame 41. A casting space is formed between the outer frame 41 and the inner frame 42. The casting space defines the shape of the wall 10. The outer frame 41 is used to define the outer shape of the wall 10, and the inner frame 42 is provided to form a window hole 11 in the middle of the wall 10 after casting.

[0047] Before pouring, the auxiliary frame 20 is fixed to the outer wall of the inner frame 42, and then materials are poured into the pouring space between the outer frame 41 and the inner frame 42 to form the wall 10. At the same time, the auxiliary frame 20 is naturally buried in the wall 10 to achieve the connection and fixation of the auxiliary frame 20 with the wall 10. In order to prevent a gap between the two, a sealant can be provided between the wall 10 and the auxiliary frame 20 to achieve reinforced sealing.

[0048] In this embodiment, the auxiliary frame 20 is made of glass fiber polyurethane material, so that the material of the auxiliary frame 20 is similar to the expansion and contraction characteristics of the cement-based material of the wall 10, thereby improving the phenomenon of a gap between the auxiliary frame 20 and the wall 10 due to the difference in thermal expansion. In addition, the auxiliary frame 20 can be formed into a variety of finishing effects including black, silver, wood, etc., to meet the requirements of the facade form design. In other alternative embodiments, the auxiliary frame 20 can also be made of polyurethane material, and the material of the auxiliary frame 20 can be selected based on actual use requirements.

[0049] In this embodiment, the outer frame 41 and the inner frame 42 are both square frame structures, and the outer wall of the outer frame 41 and the inner wall of the inner frame 42 are both provided with reinforcing ribs to ensure the overall structural strength of the mold 40. Therefore, the wall 10 formed by casting the mold 40 has a square structure. In other alternative embodiments, the shapes of the outer frame 41 and the inner frame 42 can be flexibly set based on the actual shape requirements of the wall 10.

[0050] Please refer to Figure 3 As shown, the functional structural member 22 is connected to the frame 21 , a portion of the functional structural member 22 is buried in the wall 10 , a portion is attached to the inner wall of the window opening 11 , and a portion is attached to the outer side of the wall 10 .

[0051] In this embodiment, the frame 21 is a square frame structure, the cross section of the frame 21 is a rectangular structure, and the frame 21 is entirely embedded in the wall 10. The inner wall of the frame 21 is flush with the inner wall of the window hole 11 to ensure the overall consistency of the window hole 11. In other alternative embodiments, the frame 21 may also be partially embedded in the wall 10, that is, the portion of the frame 21 close to its inner wall protrudes from the window hole 11, and the embedding method of the frame 21 may be adjusted based on actual use requirements.

[0052] Please continue to refer to Figure 2 , Figure 3 and Figure 5As shown, the window frame 30 is located in the auxiliary frame 20, the shape of the outer wall of the window frame 30 is adapted to the shape of the inner wall of the auxiliary frame 20, and the outer wall of the window frame 30 is sealed and connected to the inner wall of the auxiliary frame 20. The connection gap between the window frame 30 and the auxiliary frame 20 can be sealed by a sealant. In other alternative embodiments, the window frame 30 can also be installed on the construction site, and the auxiliary frame 20 and the window frame 30 are sealed and connected by the sealant.

[0053] Combination Figure 5 As shown, in this embodiment, the frame 21 includes four frames 211 and thermal insulation materials 212, and the four frames 211 are detachably connected end to end to form a square frame structure. The frame 211 adopts a box-type steel beam, and the frame 211 has an inner cavity. The thermal insulation material 212 is filled in the inner cavity of the frame 211 to form a high thermal insulation auxiliary frame. Since the frame 211 is hollow, adjacent frames 211 can be connected by angle codes 50 in conjunction with connecting screws. Adjacent frames 211 are distributed at right angles, so the angle code 50 is a right-angle structure, one side of the angle code 50 extends into one frame 211, and the other side extends into another frame 211, and then the screw connects the side of the angle code 50 to the corresponding frame 211 to form a stable corner connection.

[0054] In this embodiment, the heat-insulating material 212 may be polyurethane heat-insulating cotton to improve the heat-insulating performance of the frame 21. In other alternative embodiments, the heat-insulating material 212 may be selected from existing heat-insulating materials based on actual use requirements, such as polyurethane foam materials.

[0055] In this embodiment, the frame 21 includes four frames 211, each frame 211 is a straight beam structure, and the four frames 211 form a square frame structure. In other alternative embodiments, the number and shape of the frames 211 included in the frame 21 can be adjusted based on the shape adaptability of the frame 21.

[0056] Please refer to Figure 2 and Figure 3 As shown, the wall 10 includes a concrete layer 101 and an insulation layer 102 , and the insulation layer 102 is located inside the concrete layer 101 .

[0057] In this embodiment, the frame 21 is vertically opposite to the insulation layer 102, and the outer wall of the frame 21 is in contact with the insulation layer 102. The relative position relationship between the insulation layer 102 and the frame 21 is set so that the combination of the two has high thermal stability and insulation continuity.

[0058] In this embodiment, the functional structural member 22 can be used for water blocking, reinforcement, etc. Figures 2 to 4 Introduce functional structural parts 22.

[0059] Combination Figure 3 As shown, the functional structural member 22 includes a lower retaining edge 221, and the lower retaining edge 221 is attached to the lower edge of the window hole 11, and the lower retaining edge 221 is located on the side of the auxiliary frame 20 close to the outside of the wall 10. The outside of the wall 10 here refers to the side of the wall 10 located outdoors, and the inside of the wall 10 refers to the side located indoors.

[0060] In this embodiment, the lower guard edge 221 is connected to the side of the frame 21 close to the outside of the wall 10, the lower surface of the lower guard edge 221 is in contact with the lower edge of the window opening 11, and the upper surface of the lower guard edge 221 is provided with a waterproof slope 222. The waterproof slope 222 is inclined and extends downward toward the side close to the outside of the wall 10. The slope of the waterproof slope 222 can be designed to be 5%, forming a detailed structure integrating the auxiliary frame and the drainage. The setting of the waterproof slope 222 helps to guide water to flow outside the wall 10, thereby improving the waterproof performance of the exterior wall panel.

[0061] In addition, a lower side guard edge 223 is connected to the side of the lower guard edge 221 close to the outside of the wall 10, and the lower side guard edge 221 extends downward, and the lower side guard edge 223 is attached to the outside of the wall 10. The lower guard edge 221 forms a protection on the outside of the wall 10, which helps to prevent water from seeping into the gap between the lower guard edge 221 and the lower edge of the window hole 11, thereby improving the overall waterproof performance of the exterior wall panel.

[0062] Please refer to Figure 4 As shown, the functional structural member 22 further includes an upper retaining edge 224 , which is attached to the upper edge of the window hole 11 , and is located on a side of the auxiliary frame 20 close to the outside of the wall 10 .

[0063] In this embodiment, the upper retaining edge 224 is connected to the side of the frame 21 close to the outside of the wall 10, and the upper surface of the lower retaining edge 221 is in contact with the upper edge of the window hole 11. A drip groove 225 is provided on the lower surface of the upper retaining edge 224. The provision of the drip groove 225 can prevent water from flowing along the lower surface of the lower retaining edge 221 to the inside of the wall 10, and on the other hand, it is conducive to the water dripping downwards. At the same time, the drip groove 225 is provided with a downward opening, and it is not easy to store dirt.

[0064] In this embodiment, the drip groove 225 is a rectangular groove. In other alternative embodiments, the drip groove 225 may be an arc-shaped groove or a groove of other shapes.

[0065] The upper retaining edge 224 is connected to an upper side retaining edge 226 on one side close to the outside of the wall 10, and the upper side retaining edge 226 extends upward and is attached to the outer side of the wall 10. The upper retaining edge 224 forms a protection on the outer side of the wall 10, which helps to prevent water from seeping into the gap between the upper retaining edge 224 and the upper edge of the window hole 11, improves the overall waterproof performance of the exterior wall board, and forms an integrated detailed structure of the attached frame and the drip.

[0066] The functional structural member 22 further includes a blocking member 227 . The blocking member 227 is embedded in the wall 10 , and the blocking member 227 is arranged at an angle with the horizontal direction.

[0067] Please continue to refer to Figure 3 and Figure 4 As shown, in this embodiment, the blocking member 227 is at a right angle to the horizontal direction, and the blocking member 227 is a plate structure. The blocking member 227 is located on the side of the thermal insulation layer 102 close to the outside of the wall 10; the blocking member 227 is connected below the lower retaining edge 221 and above the upper retaining edge 224. The blocking member 227 not only helps to stably connect the auxiliary frame 20 to the wall 10, but also plays a waterproof function similar to the role of a water stop.

[0068] In this embodiment, the blocking member 227 is disposed on the lower blocking edge 221 and the upper blocking edge 224 to prevent water seepage. In other alternative embodiments, blocking edges may be disposed on all four sides of the frame 21, and the blocking member 227 may be connected to each blocking edge. The location of the blocking edge and the location of the blocking member 227 may be flexibly adjusted based on actual use requirements.

[0069] In this embodiment, the blocking member 227 is vertically arranged at a right angle to the horizontal direction. In other alternative embodiments, the blocking member 227 can be arranged to be inclined relative to the horizontal direction, for example, the blocking member 227 can be appropriately inclined toward the inner side of the wall 10, and the angle of the blocking member 227 can be flexibly adjusted based on actual use requirements.

[0070] Please continue to refer to Figure 3 and Figure 4 As shown, the functional structural member 22 further includes a reinforcing member 228 , and the reinforcing member 228 is buried in the wall 10 , and the reinforcing member 228 is arranged at an angle with the vertical direction.

[0071] In this embodiment, the reinforcing member 228 is connected to the side of the frame 21 close to the wall 10. The reinforcing member 228 is a plate-like structure and extends horizontally. One side surface is flush with the outer wall surface of the frame 21, and the other side surface is an inclined surface, so that the thickness of the reinforcing member 228 is gradually changed, wherein the side connected to the frame 21 is the thickest, and the side close to the wall 10 is the thinnest. By setting the reinforcing member 228, the auxiliary frame 20 is stably connected to the wall 10.

[0072] In other alternative embodiments, the reinforcement member 228 may also be a rod-type structure, a sawtooth structure, etc. The structure of the reinforcement member 228 and the angle between the reinforcement member 228 and the vertical direction may be adjusted based on actual use requirements.

[0073] Please continue to refer to Figure 3 As shown, the functional structural member 22 further includes a protrusion 229, which is arranged at the lower edge of the inner wall of the auxiliary frame 20, and the protrusion 229 is conformably embedded in the outer wall of the window frame 30. Here, the inner wall of the auxiliary frame 20 is taken as a reference to the entire auxiliary frame 20, the side wall located in the cavity formed by the auxiliary frame 20 itself is taken as the inner wall, and the side wall located outside the cavity of the auxiliary frame 20 is taken as the outer wall. Here, the outer wall of the window frame 30 is taken as a reference to the entire window frame 30, the side wall located in the cavity formed by the window frame 30 itself is taken as the inner wall, and the side wall located outside the cavity of the window frame 30 is taken as the outer wall.

[0074] In this embodiment, the protrusion 229 is a rectangular boss structure, and the lower edge of the corresponding outer wall of the window frame 30 has a groove, and the protrusion 229 is conformably mounted in the groove. The setting of the protrusion 229 forms a water retaining structure of the window system, further improving the waterproofing measures, and the protrusion 229 is also used to assist the installation of the window frame 30 and improve the firmness of the installation of the window frame 30.

[0075] In this embodiment, each part of the functional structural member 22 is integrally formed, and the functional structural member 22 is also integrally formed with the frame 21. The integrally formed auxiliary frame has better structural strength, better bonding performance with the wall, and more reliable waterproof performance.

[0076] The connection method in the above-mentioned prefabricated cement-based exterior wall panels with integrated exterior window frames is suitable for mass production in factories, has low requirements for on-site installation, good waterproof performance, and the connection nodes can meet the design specifications and related high-performance requirements of ultra-low energy consumption or near-zero energy consumption.

[0077] The above-mentioned prefabricated cement-based exterior wall panel with integrated exterior window frame has a higher degree of integration of the wall 10 and the frame 20, and can better organically connect the prefabricated cement-based exterior wall enclosure system with the window system, which can not only ensure the stability of the wall's thermal insulation performance, increase waterproof measures through the setting of the functional structural parts 22, but also improve the waterproof performance of the connection between the wall and the window system, improve the durability of building materials, and simplify the construction process and improve on-site work efficiency.

[0078] Waterproof measures are added by setting the functional structural member 22. Overall, the cement-based exterior wall panel has a simple structure, low construction difficulty, and low cost, which is conducive to large-scale promotion and application.

[0079] Combination Figure 6As shown, another embodiment of the prefabricated cement-based exterior wall panel with integrated exterior window frame is shown. Figure 2 The difference lies in the difference in the structure of the functional structural member 22 and the difference in the relative position relationship between the auxiliary frame 20 and the thermal insulation layer 102 .

[0080] The frame 21 is disposed on a side of the thermal insulation layer 102 close to the inside of the wall 10 , and a side of the frame 21 close to the outside of the wall 10 is disposed in close contact with the thermal insulation layer 102 .
