Description

Technical Field

[0001] This utility model belongs to the field of template technology, and more specifically, it relates to an integrated template for basement exterior walls. Background Technology

[0002] In the field of building construction, the waterproofing and insulation performance of basement exterior walls are key factors in ensuring the overall quality and functionality of a building. Basement exterior walls are constantly exposed to a complex underground environment. If waterproofing measures fail to meet standards, groundwater will seep in through every crack, causing continuous erosion of the building structure. This not only significantly shortens the building's lifespan but also greatly increases the likelihood of dampness and mold growth inside, severely impacting the building's normal functionality. Traditional methods require manual assistance to lay waterproofing and insulation materials separately. This process involves multiple complex steps, consuming significant manpower, resources, and time. Furthermore, the excessive number of construction steps can lead to quality issues. On the other hand, the significant influence of human factors during construction results in poor consistency in the quality of waterproofing and insulation, making it difficult to guarantee ideal results at every stage of construction. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an integrated formwork for basement exterior walls, solving the technical issue that traditional devices require manual assistance to lay waterproof and insulation materials separately.

[0004] The purpose and effect of this utility model of an integrated formwork for basement exterior walls are achieved by the following specific technical means:

[0005] An integrated formwork for basement exterior walls includes an anti-corrosion frame. Inside the anti-corrosion frame, a cement board protective layer, an insulation layer, a waterproof layer, and a cement filler board are sequentially arranged. The anti-corrosion frame is equipped with a quick-connect upper receiving plate and a quick-connect lower protrusion at its bottom. A left connecting plate and a right connecting clamping plate are also provided on the anti-corrosion frame. Protective outer netting is installed on both sides of the anti-corrosion frame. The insulation layer has multiple sets of arc-shaped grooves, each with multiple sets of aluminized reflective film. An expansion sealing strip is fitted onto the waterproof layer, and multiple sets of breathable insulating cotton are clamped onto the waterproof layer.

[0006] According to a preferred embodiment, the cement board protective layer and the insulation layer are connected by construction adhesive, and the insulation layer, the waterproof layer, and the cement filler board are all connected by adhesive.

[0007] According to a preferred embodiment, the insulation layer is made of polystyrene foam board, and the insulation layer thickness is 80-120 mm.

[0008] According to a preferred embodiment, the waterproof layer is made of ethylene waterproof membrane, and the thickness of the waterproof layer is 1.2-1.5 mm.

[0009] According to a preferred embodiment, the cement filler board is provided with reinforcing ribs, the cement filler board is provided with multiple sets of fiberglass mesh, and the thickness of the cement filler board is 5 mm.

[0010] According to a preferred embodiment, the cement board protective layer is made of lightweight ceramsite, the thickness of the cement board protective layer is 10-15 mm, and sealing rings are provided on both sides of the anti-corrosion frame, with the sealing rings fitting into the cement board protective layer.

[0011] According to a preferred embodiment, the quick-connect upper receiving plate is provided with multiple sets of fixing threaded plates, and both the quick-connect upper receiving plate and the quick-connect lower protrusion are connected to the anti-corrosion frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device utilizes an 80-120 mm thick polystyrene foam board insulation layer with multiple arc-shaped grooves featuring an aluminized reflective film, and a 1.2-1.5 mm thick ethylene waterproof membrane waterproofing layer with an expansion seal strip. This combination provides users with both thermal insulation and waterproofing performance. The polystyrene foam board insulation layer, with its arc-shaped grooves and aluminized reflective film working synergistically, enhances heat transfer resistance. The ethylene waterproof membrane waterproofing layer effectively prevents moisture penetration, and the expansion seal strip expands upon contact with water to fill any gaps, further improving waterproofing capabilities.

[0014] 2. When using this device, users can connect the insulation layer and the protective cement board layer with construction adhesive, and connect the insulation layer with the waterproof layer and the cement filler board with adhesive. This ensures a firm bond between the insulation layer and each layer, preventing displacement or detachment and ensuring stable insulation performance. It also guarantees the integrity of the waterproof layer, improving the stability of the device's insulation and waterproofing structure. Furthermore, by installing breathable insulation material between the insulation and waterproof layers, the device can balance internal moisture pressure while ensuring waterproofing, preventing moisture accumulation from affecting the insulation effect, extending the service life of the insulation and waterproofing materials, and improving the reliability of the device's insulation and waterproofing performance during long-term use.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 2As shown, this utility model provides an integrated formwork for basement exterior walls, including an anti-corrosion frame 11. The anti-corrosion frame 11 serves as the core frame of the entire formwork, supporting and protecting the interior structure, while also providing a basic framework for connections between formwork sections. This ensures that the entire basement exterior wall structure can withstand erosion and external forces from the complex underground environment during long-term use, maintaining structural integrity and stability. Inside the anti-corrosion frame 11, there are sequentially arranged cement board protective layers 12, insulation layers 13, waterproof layers 14, and cement filling boards 15. The cement board protective layer 12 is made of lightweight expanded clay aggregate, with a thickness of 10-15 mm. It provides initial internal protection for the entire exterior wall structure, preventing external physical impacts from damaging the internal insulation and waterproof layers. Simultaneously, it fits snugly against the sealing rings 22 on both sides of the anti-corrosion frame 11, providing a seal to prevent external moisture, dust, and other impurities from entering the internal structure, enhancing overall protective performance. The insulation layer 13 is made of polystyrene foam board, with a thickness of 80-120 mm. The insulation layer 13 serves as the thermal insulation layer in the entire system, effectively reducing heat transfer between the basement's exterior walls and the interior, thus lowering the building's energy consumption. Multiple arc-shaped grooves on the insulation layer 13, along with multiple sets of aluminized reflective films 25 mounted on these grooves, further enhance the insulation effect. The aluminized reflective films 25 reflect heat, reducing heat absorption, while the arc-shaped grooves increase airflow space, aiding in insulation. The insulation layer 13 is connected to the cement board protective layer 12 via construction adhesive and to the waterproof layer 14 and cement filler board 15 via adhesive. This design ensures the insulation layer 13 is bonded to the other layers, preventing delamination and displacement, and guaranteeing stable insulation performance. The waterproof layer 14 is made of ethylene waterproof membrane with a thickness of 1.2-1.5 mm. The waterproof layer 14 is the last line of defense against groundwater leakage; its waterproof performance effectively prevents groundwater from seeping into the basement, protecting the basement's structure and interior space from water damage. The expansion seal strip 24 fitted onto the waterproof layer 14 expands upon contact with moisture, further filling any gaps and enhancing the waterproofing effect. Simultaneously, multiple sets of breathable insulating cotton 26 embedded in the waterproof layer 14 balance internal moisture pressure while ensuring waterproofing, preventing moisture accumulation from affecting the insulation effect or damaging the waterproof layer 14, thus extending the service life of the waterproofing and insulation materials. The waterproof layer 14 is connected to the insulation layer 13 and the cement filler board 15 with adhesive, ensuring the integrity and stability of the waterproof structure. The cement filler board 15 is 5 mm thick, with reinforcing ribs 27 and multiple sets of fiberglass mesh 23. As the supporting foundation of the entire structure, the cement filler board 15 provides strength and rigidity to the basement exterior wall, bearing external pressure. The reinforcing ribs 27 and fiberglass mesh 23 further enhance the structural strength and toughness of the cement filler board 15, effectively preventing cracks or damage when subjected to external forces, ensuring the basement exterior wall can withstand various external forces.The anti-corrosion frame 11 is equipped with a quick-connect upper receiving plate 16, on which multiple sets of fixing threaded plates 28 are threaded. It connects to the anti-corrosion frame 11, providing an upper docking structure for connecting adjacent formwork. The quick-connect upper receiving plate 16 cooperates with a quick-connect lower protrusion 17, which is located at the bottom of the anti-corrosion frame 11. Together, they achieve a quick, convenient, and stable vertical connection between adjacent formwork. During construction, this significantly improves formwork installation efficiency, reduces construction time and costs, and ensures the stability of the connection points, guaranteeing the integrity of the entire basement exterior wall structure. The anti-corrosion frame 11 also has a left connecting plate 18 and a right connecting plate 19, located on both sides of the frame, primarily for lateral connection between formwork. The left connecting plate 18 and right connecting plate 19 allow adjacent formwork to be spliced ​​together horizontally, further enhancing the stability and integrity of the basement exterior wall structure and effectively resisting external forces from the horizontal direction. Both sides of the anti-corrosion frame 11 are equipped with protective outer nets 21. The protective outer nets 21 provide additional protection for the internal functional layers, preventing damage to the internal cement board protective layer 12, insulation layer 13, waterproof layer 14 and cement filling board 15 caused by external sharp objects or mechanical collisions. This improves the protective performance of the entire integrated formwork and extends its service life.

[0024] like Figures 2 to 4As shown, when using this device, the anti-corrosion frame 11 is firmly constructed around the perimeter of the basement exterior wall. As the core framework of the entire formwork, it bears the weight of each internal functional layer and resists adverse factors such as soil pressure and groundwater erosion in the complex underground environment. Simultaneously, it provides a reliable foundation for the connection between formwork sections, ensuring the stable operation of the entire basement exterior wall structure during long-term use. The cement board protective layer 12, located inside the anti-corrosion frame 11, is made of lightweight expanded clay aggregate and is 10-15 mm thick. It provides a preliminary protective barrier for the entire exterior wall structure, effectively buffering external physical impacts and preventing direct damage to the internal insulation layer 13 and waterproof layer 14 from sharp objects or external forces. At the same time, the cement board protective layer 12 cooperates with the sealing rings 22 attached to both sides of the anti-corrosion frame 11 to form a sealed structure, effectively preventing external moisture, dust, and other impurities from intruding into the internal structure, greatly enhancing the protective performance of the entire device. The insulation layer 13 is installed immediately adjacent to the cement board protective layer 12. It is made of polystyrene foam board with a thickness of 80-120 mm and serves as the thermal insulation layer in the entire formwork system. It effectively prevents heat transfer between the interior and exterior of the basement walls, significantly reducing the building's energy consumption and creating a relatively stable temperature environment for the basement. Multiple sets of arc-shaped grooves and multiple sets of aluminized reflective films 25 installed within the grooves further enhance the insulation effect. The aluminized reflective film 25 has excellent heat reflection capabilities, reflecting most of the radiant heat back and reducing heat absorption; while the arc-shaped grooves increase airflow space, utilizing the insulating properties of air to assist in insulation. The insulation layer 13 is firmly connected to the cement board protective layer 12 with construction adhesive, and simultaneously bonded to the waterproof layer 14 and cement filler board 15 with adhesive, ensuring the stability of the insulation layer 13 within the entire structure and preventing delamination, displacement, or other issues, thus guaranteeing that the insulation performance remains consistently effective. The waterproof layer 14, immediately following the insulation layer 13, is made of ethylene waterproof membrane with a thickness of 1.2-1.5 mm, preventing groundwater seepage. Its waterproof performance effectively blocks groundwater penetration, providing comprehensive protection for the basement structure and interior space from water erosion. An expansion stop strip 24, specially fitted onto the waterproof layer 14, possesses the special property of expanding upon contact with water. When moisture comes into contact with the expansion stop strip 24, it expands rapidly, filling any gaps and further enhancing the waterproof effect, ensuring complete waterproofing. Multiple sets of breathable insulating cotton 26 are embedded in the waterproof layer 14, balancing internal moisture pressure while maintaining good waterproof performance. This effectively prevents a decrease in insulation performance due to moisture accumulation or damage to the waterproof layer 14 itself, thus extending the service life of the waterproof and insulation materials. The waterproof layer 14 is connected to the insulation layer 13 and the cement filler board 15 with adhesive, ensuring the integrity and stability of the waterproof structure, enabling it to effectively resist groundwater seepage for a long time.The cement filler slab 15, 5 mm thick, serves as the foundational support for the entire structure and is securely installed on the innermost side. It is reinforced with ribs 27 and multiple sets of fiberglass mesh 23, significantly enhancing its structural strength and toughness. The cement filler slab 15 provides strength and rigidity, enabling it to reliably withstand various external pressures, while the fiberglass mesh 23 enhances its crack resistance, effectively preventing cracks or damage under external forces. This ensures the basement exterior wall can reliably withstand various external forces and maintain structural stability. A quick-connect upper receiving plate 16 is installed on the anti-corrosion frame 11, with multiple sets of threaded plates 28 threaded through its surface. Connecting to the anti-corrosion frame 11, it provides a stable upper connection structure for connecting adjacent formwork panels. The quick-connect upper receiving plate 16 and the quick-connect lower protrusion 17 located at the bottom of the anti-corrosion frame 11 cooperate with each other. During actual construction, construction workers can easily embed the quick-connect lower protrusion 17 of adjacent templates into the quick-connect upper receiving plate 16, and then tighten it with the fixing thread plate 28, thereby achieving a quick, convenient and stable vertical connection between adjacent templates. This connection method not only greatly improves the installation efficiency of the templates, effectively shortens the construction time, and reduces the construction cost, but also ensures the stability of the connection parts, making the entire basement exterior wall structure a stable whole in the vertical direction. The left connecting plate 18 and the right connecting plate 19 on the anti-corrosion frame 11 are located on both sides of the anti-corrosion frame 11, mainly used to achieve horizontal connection between templates. During construction, the left connecting plate 18 and the right connecting plate 19 of adjacent templates can be spliced ​​together and fixed by bolts, so that the adjacent templates are firmly combined into one in the horizontal direction. The left connecting plate 18 and the right connecting plate 19 further enhance the stability and integrity of the basement exterior wall structure in the horizontal direction, enabling it to effectively resist external forces from the horizontal direction. The protective nets 21 set on both sides of the anti-corrosion frame 11 provide additional protection for the internal cement board protective layer 12, insulation layer 13, waterproof layer 14 and cement filling board 15.

[0025] The specific usage and function of this embodiment are as follows:

[0026] During use, the quick-connect lower protrusion 17, quick-connect upper receiving plate 16, and fixing threaded plate 28 are used to achieve quick and stable upper and lower splicing between templates. Then, the left connecting plate 18 and right connecting clamping plate 19 are used to complete the horizontal connection. Subsequently, the template is installed in the designated position, and the anti-corrosion frame 11 provides stable support for the entire process. Before being put into use, the cement board protective layer 12, together with the sealing ring 22, prevents impurities from entering, and the protective mesh 21 enhances physical protection and reduces the risk of damage to the internal structure. The insulation layer 13 uses polystyrene foam board of a specific thickness, combined with arc grooves and aluminum-plated reflective film 25, to effectively block heat transfer and reduce energy consumption. The waterproof layer 14 is based on ethylene waterproof membrane, combined with water-swellable waterstop strips 24, to build a reliable waterproof system, prevent groundwater infiltration, and improve the overall quality and durability of the building.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
