As building construction has evolved, exterior wall decoration materials have become increasingly complex and diverse, with more and more materials being used. Stone curtain walls are one of the most widely used exterior wall decoration materials.

[0003] In some existing technologies, the design of certain devices sometimes places the building's rainwater drainage vertical pipes in the cavity between the main structure and the stone curtain wall. According to the relevant specifications for rainwater drainage pipes, an inspection port needs to be installed at a height of one meter above the outdoor ground. Therefore, during the process of decorating the exterior wall with stone curtain wall, it is necessary to install corresponding maintenance covers according to the location of the pipe inspection port.

[0004] However, in practical use, when the material of the decorative cover plate does not match the overall exterior wall decoration, it will create a visually jarring effect. Stone curtain walls typically strive for overall harmony and unity; inconsistent materials will disrupt the overall aesthetic appeal of the building facade. Just like a discordant patch of color in a meticulously painted artwork, it significantly diminishes the quality and artistic atmosphere of the entire building's appearance. Therefore, to address the above-mentioned problems, a decorative cover plate for pipe inspection holes in stone curtain walls is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a decorative cover plate for pipe inspection holes in stone curtain walls, aiming to improve the problem that some decorative cover plate materials in the prior art cannot maintain consistency with the overall exterior wall decoration.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 3This invention relates to a decorative cover plate for pipe inspection holes in stone curtain walls, comprising a wall body 1. The wall body 1 serves as the foundational load-bearing component of the entire building structure, playing a crucial supporting role. The wall body 1 is typically constructed from robust and durable building materials such as concrete and masonry. Its internal structure is carefully designed and constructed, possessing sufficient strength and stability. A main frame column 2 is fixedly connected to the front of the wall body 1. The cross-sectional shape and dimensions of the main frame column 2 are determined according to architectural design requirements and load-bearing capacity calculations, and are commonly rectangular. The connection between the column and the wall body 1 employs reliable anchoring methods, such as chemical anchors, expansion bolts, or pre-embedded steel plate welding. The connection points undergo rigorous quality testing to ensure a firm connection and uniform force transmission, effectively transferring the weight of the stone curtain wall and related ancillary structures to the wall body 1. Simultaneously, it maintains the overall structural stability under various working conditions, preventing safety accidents such as displacement, deformation, or collapse. A stone curtain wall body 4 is fixedly connected to the exterior of the wall body 1. The stone curtain wall body 4 serves as the decorative and protective surface layer of the building's exterior wall, giving the building a unique appearance and stylistic character. The stone curtain wall body 4 utilizes a wide variety of stone types, commonly including granite and marble. These stones are characterized by their hardness, beautiful color, and durability. Both the upper and lower ends of the stone curtain wall body 4 are fixedly connected to horizontal stone curtain wall studs 3. These studs 3 are horizontal support components within the stone curtain wall structural system, and their material matches that of the main frame columns 2, typically being metal profiles. The length of the horizontal studs 3 is determined according to the curtain wall's panel dimensions. Their installation positions on the wall 1 or main frame columns 2 are precisely measured and positioned, and they are welded together to form a unified frame structure.

[0025] External wall pipes 5 are fixedly connected to the horizontal keel 3 of the stone curtain wall. These pipes serve as a connection channel between various internal building systems and the external environment, undertaking the important function of transporting liquids, gases, or cables. The material of the external wall pipes 5 is selected according to the medium being transported and the requirements of the operating environment; common types include metal pipes (such as galvanized steel pipes and stainless steel pipes) and plastic pipes (such as PVC pipes and PPR pipes). The connection between the external wall pipes 5 and the horizontal keel 3 of the stone curtain wall typically uses pipe clamps, clamps, or welded supports. The connection points undergo appropriate anti-corrosion and anti-rust treatment to ensure that the pipes will not leak or be damaged due to loose connections or corrosion during long-term use. A round steel rotating shaft 6 is fixedly connected to one side of each of the two horizontal keels 3 of the stone curtain wall. This round steel rotating shaft 6 is a key component for realizing the rotating opening and closing function of the inspection door decorative cover 10. Its material is generally high-quality carbon steel or alloy steel, possessing good strength and toughness. The diameter of the round steel rotating shaft 6 is determined based on the size and weight of the inspection door decorative cover 10 and the required rotational flexibility. Its surface is finely machined to achieve high roundness and smoothness, reducing frictional resistance with the steel pipe sleeve 7 and ensuring smooth rotation. The round steel rotating shaft 6 is externally rotatably connected to the steel pipe sleeve 7. The steel pipe sleeve 7, as a component that cooperates with the round steel rotating shaft 6 to achieve rotational movement, is generally made of steel pipe, possessing certain strength and wear resistance. The inner diameter of the steel pipe sleeve 7 precisely matches the diameter of the round steel rotating shaft 6, with tolerances controlled within a very small range to ensure the fitting accuracy between the two, achieving smooth rotation without excessive clearance that could cause wobbling or misalignment. An angle steel 8 is externally fixedly connected to the steel pipe sleeve 7. The angle steel 8, as a transitional component connecting the steel pipe sleeve 7 and the angle steel frame 9, is typically made of angle steel, possessing good structural strength and processing performance. The specifications of angle steel 8 are determined according to the load it bears and the connection requirements with other components. Its connection with the steel pipe bushing 7 is made by welding, and the welded parts are reinforced to ensure a firm connection.

[0026] Angle steel frame 9 is externally fixed to angle steel 8. Angle steel frame 9 serves as the supporting framework for the inspection door decorative cover 10. It is made of angle steel, and multiple angle steels are combined to form a rectangular or other shaped frame structure through welding or bolting. The dimensions of angle steel frame 9 are designed according to the size of the inspection door decorative cover 10 and the specifications of the pipe inspection hole in the stone curtain wall. The corners of the frame are rounded or specially treated to avoid accidental injury to personnel during use. The inspection door decorative cover 10 is externally fixed to angle steel frame 9. As a component directly exposed on the building facade, the inspection door decorative cover 10 must not only fulfill the function of covering the pipe inspection hole but also have a good decorative effect, coordinating and unifying with the overall style of the stone curtain wall body 4. The material of the inspection door decorative cover 10 can be the same as or similar to that of the stone curtain wall body 4. It is made of stone slabs and its surface is finely processed and polished, with the same color, texture and gloss as the curtain wall stone, so that the entire curtain wall surface looks seamless and without obvious abruptness.

[0027] Reference Figures 3 to 4 The access door decorative cover 10 has a sliding rod 11 internally connected. The sliding rod 11 is a key transmission component in the opening and closing operation of the access door, and its material is generally metal, such as aluminum alloy or stainless steel, to ensure good strength and wear resistance. A spring 12 is internally installed in the access door decorative cover 10, playing a crucial role in elastic reset and auxiliary locking. The spring 12 is carefully manufactured from high-quality spring steel, and its elastic coefficient is precisely calculated and designed based on factors such as the size and weight of the access door decorative cover 10 and the required locking force. A connecting frame 13 is externally fixed to the sliding rod 11. The connecting frame 13 serves as an intermediate transition structure connecting the sliding rod 11 and the rotating plate 14. Its material is mostly metal, such as angle steel or steel plate, possessing sufficient strength and rigidity to withstand the various forces transmitted during the operation of the access door.

[0028] A rotating plate 14 is rotatably connected to the external side of the connecting frame 13. The rotating plate 14 is a key component that converts the movement of the connecting frame 13 into the action of the insertion rod 16. Its material is generally metal, such as steel plate or aluminum plate, which has a certain strength and toughness. The shape and size of the rotating plate 14 are designed according to its position and function in the transmission chain. One end of it is rotatably connected to the connecting frame 13, and the other end is rotatably connected to the connecting frame 15. Through its own rotation angle change, it cleverly transmits the linear motion of the connecting frame 13 to the connecting frame 15, thereby driving the insertion rod 16 to achieve the action of engaging or disengaging with the slot 18, thereby controlling the locking and opening state of the inspection door decorative cover 10. The other end of the rotating plate 14 is rotatably connected to the connecting frame 15. The connecting frame 15, as the component connecting the rotating plate 14 and the insertion rod 16, is usually made of metal, such as aluminum alloy or stainless steel, which has good strength and a certain degree of flexibility so that it can adapt to forces of different directions and magnitudes during the force transmission process. An insertion rod 16 is externally fixed to the connecting frame 15. The insertion rod 16 is a component that directly engages with the external slot 18 of the stone curtain wall body 4. Its material is generally metal, such as alloy steel or stainless steel, which has high hardness and wear resistance to ensure that it will not wear or deform due to frequent engagement and disengagement during long-term use. A handle 17 is externally fixed to the sliding rod 11. The handle 17 is externally slidably connected to the outside of the inspection door decorative cover 10. The inspection door decorative cover 10 has a special slide or groove at a corresponding position. The size of the slide or groove is adapted to the shape of the handle 17, and the tolerance is controlled within a small range to ensure that the handle 17 can slide smoothly in it without shaking or shifting during the sliding process. This allows the operator to accurately control the movement of the sliding rod 11 through the handle 17, thereby realizing the opening and closing operation of the inspection door decorative cover 10.

[0029] The handle 17 is externally slidably connected to the exterior of the access door decorative cover 10. A slot 18 is provided on the exterior of the stone curtain wall body 4. The slot 18 serves as a structure for engaging with the insertion rod 16. Its shape and size are designed according to the shape of the insertion rod 16, generally a rectangular or trapezoidal groove. The depth and width of the slot 18 ensure that the insertion rod 16 is stably engaged within it, and that it will not loosen or come out in the engaged state. The exterior of the insertion rod 16 engages with the exterior of the slot 18. When the insertion rod 16 is accurately inserted into the slot 18 under the preload of the spring 12 and the transmission action of related components, the insertion rod 16 is in close contact with the inner wall of the slot 18. The friction between the two and the limiting effect of the slot 18 on the insertion rod 16 together prevent the access door decorative cover 10 from being accidentally opened. The rotating plate 14 is externally rotatably connected to the inside of the inspection door decorative cover 10, and the insertion rod 16 is externally slidably connected to the inside of the inspection door decorative cover 10. The outside of the inspection door decorative cover 10 is rotatably connected to the outside of the stone curtain wall body 4, and the outside of the inspection door decorative cover 10 is in contact with the outside of the external wall pipe 5. One end of the spring 12 is fixedly connected to the inside of the inspection door decorative cover 10, and the other end of the spring 12 is fixedly connected to the outside of the insertion rod 16. Under normal conditions, the spring 12 is in a certain compressed or stretched state, providing support for the insertion rod 16. A preload force keeps the insertion rod 16 engaged with the slot 18. When the access door needs to be opened, an external force overcomes the preload force of the spring 12, causing the spring 12 to be further compressed or stretched, and the insertion rod 16 disengages from the slot 18, thus opening the access door decorative cover 10. When the external force disappears, the spring 12 releases its elastic potential energy, causing the insertion rod 16 to return to its initial position and re-engage with the slot 18, thus closing and locking the access door decorative cover 10. This achieves the automatic locking and reset function of the access door, improving the convenience and safety of the access door.

[0030] Working principle: Based on the curtain wall reinforcement structure, a steel keel anchor bolt dry-hanging structure is generally adopted. A fixed-size square inspection port is fixed on the back side with L40*4mm angle steel. The fixed angle steel is vertically welded to the steel pipe sleeve shaft (φ28*3mm steel pipe). Then, a rotating shaft (using φ20 round steel welded to the curtain wall horizontal keel) is sleeved on the inside of the steel pipe to form a rotatable device for opening. The openable side and the rotating shaft side of the square inspection port are both cut at a 45° bevel to facilitate the opening of the inspection port. In this way, an openable concealed inspection port is formed in the curtain wall decorative inspection port.

[0031] During the opening process, an external force is applied to the handle 17, pulling the sliding rod 11. This causes the sliding rod 11 to rotate the rotating plate 14, allowing the insertion rod 16, which was originally tightly engaged with the slot 18 on the stone curtain wall body 4, to disengage from the slot 18 after the external force overcomes the preload of the spring 12. The cover then opens. The spring 12 assists in locking and resetting during this process. When the external force disappears, releasing the sliding rod 11 allows the spring 12 to push the insertion rod 16 back into the access door decorative cover 10, re-locking the cover and ensuring it remains closed when not in use. Furthermore, the cover's rotation is supported by the round steel rotating shaft 6 and the steel pipe bushing 7, ensuring smooth rotation during opening and closing.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
