Description

Technical Field

[0001] This utility model relates to the technical field of fixing and installing rainwater pipes in light steel structures, specifically to a PVC rainwater pipe fixing structure and its system. Background Technology

[0002] As an essential component of buildings, rainwater pipes are constantly evolving with the increasing variety of modern building forms and materials, and the continuous upgrading of exterior wall materials. However, the fixing between the two is often overlooked, resulting in frequent occurrences of rainwater pipes falling off or breaking.

[0003] To overcome this issue during the architectural design process, many manufacturers of building exterior wall materials have designed matching rainwater pipes based on the characteristics of their own materials, perfectly solving the connection problem. For example, they have developed rainwater pipes made of color steel plates and aluminum alloys, whose colors match the exterior walls in an aesthetically pleasing manner. Furthermore, due to the similarity of materials, the fixed accessories are easy to match and use, ensuring the long-term use of the rainwater system.

[0004] PVC rainwater pipes, as an economical rainwater pipe material, are still widely used in industrial plants. Rainwater pipe manufacturers are constantly improving the matching connectors, but due to the limitations of standardized product manufacturing, they are difficult to adapt to complex engineering construction.

[0005] The main problems currently exist as follows:

[0006] (1) The matching steel nails need to be welded, which will damage the galvanized layer or other protective layers of the light steel structure.

[0007] (2) When the connector penetrates the wall material such as steel plate or aluminum plate, it will cause water leakage or corrosion of the wall material.

[0008] (3) Once the welding is completed, the position is not easy to adjust, which may cause the rainwater pipe installation to be uneven, thus affecting the overall service life of the rainwater pipe.

[0009] (4) When rainwater passes through the rainwater pipe, a dynamic load is formed, the welding point is prone to fatigue damage, and the connection with the wall material will also vibrate, causing the leak prevention measures to fail. Utility Model Content

[0010] To address the problems of poor adjustability, poor weather resistance, and easy corrosion of wall materials, leakage caused by damage to the wall material structure, and detachment of the rainwater pipe system due to its own detachment, this utility model provides a PVC rainwater pipe fixing structure and system.

[0011] The present invention adopts the following technical solution:

[0012] On one hand, this utility model provides a PVC rainwater pipe fixing structure, which is fixedly connected to a light steel enclosure. The fixing structure includes a support panel and a receiving panel rigidly connected to the support panel. A fastening adjustment connector is fixed between the receiving panel and the support panel and is arranged perpendicularly to the support panel. The fastening adjustment connector has an internal thread for threaded connection with a screw. One end of the fastening adjustment connector is fixedly connected to the support panel, and the other end extends out of the outer side of the receiving panel and forms a threaded connection with the screw.

[0013] Preferably, the fastening and adjusting connector is a long nut.

[0014] More preferably, the supporting panel is a large C-shaped steel plate, the receiving panel is a small C-shaped steel plate, the opening orientation of the large C-shaped steel plate is opposite to the opening orientation of the small C-shaped steel plate, a folded edge of the large C-shaped steel plate and a folded edge of the small C-shaped steel plate are joined to form a rigid whole, and the fastening and adjusting connector passes through the small C-shaped steel plate and is fixedly connected to the large C-shaped steel plate.

[0015] On the other hand, this utility model also provides a PVC rainwater pipe fixing system. The system includes a light steel enclosure, a fixing structure, a rainwater pipe, and a pipe clamp. The fixing structure is the aforementioned fixing structure. The support panel of the fixing structure is fixed to the frame of the light steel enclosure by self-tapping screws. A flexible weather-resistant rubber pad is provided between the support panel and the light steel enclosure. A screw is connected to the fastening adjustment connector. The other end of the screw is threadedly connected to the pipe clamp. The pipe clamp is fixed in a ring shape to the outer surface of the rainwater pipe.

[0016] Preferably, the flexible weather-resistant pad is an EPDM rubber pad.

[0017] The technical solution of this utility model has the following advantages:

[0018] A. The PVC rainwater pipe fixing structure of this utility model can meet the connection function between the rainwater pipe and the light steel enclosure system, and avoid causing new damage to the enclosure system.

[0019] B. The shape of the contact surface between the support panel and the light steel enclosure used in this utility model can be adjusted according to different types of light steel enclosure materials to improve its adaptability; the use of long nuts as fastening and adjusting connectors and the use of bolt connection methods facilitates the partial or complete replacement of rainwater pipes in the later stages, and ensures the overall straightness and aesthetics of the rainwater pipes; even if large-scale modifications are made to the rainwater system in the later stages, only the screw rods need to be replaced, which will not cause new damage to the enclosure system and thus affect the service life of the enclosure system.

[0020] C. A flexible weather-resistant rubber pad is provided between the support panel and the light steel enclosure used in this utility model. The flexible weather-resistant rubber pad is preferably an EPDM rubber pad. The EPDM weather-resistant rubber pad ensures that the fixed structure will not be corroded by friction or uneven stress. At the same time, it can alleviate the friction between the fixed structure and the light steel enclosure system caused by the shaking of the rainwater pipe when rainwater passes through the rainwater pipe. All of the above ensures the integrity of the light steel enclosure system and improves the overall waterproof performance. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 , Figure 2 As shown, this utility model provides a PVC rainwater pipe fixing structure, which is fixedly connected to a light steel enclosure 3. The fixing structure 1 includes a support panel 11 and a receiving panel 12 rigidly connected to the support panel 11. A fastening and adjusting connector 13 is fixed between the receiving panel 12 and the support panel 11 and is arranged perpendicularly to the support panel 11. The fastening and adjusting connector 13 has an internal thread for threaded connection of a screw 2. One end of the fastening and adjusting connector 13 is fixedly connected to the support panel 11, and the other end extends out of the outer surface of the receiving panel 12 and forms a threaded connection with the screw 2.

[0035] The preferred fastening and adjusting connector 13 is preferably a long nut with a certain thread depth, which can be used to adjust the screw depth of the screw 2 connected to it.

[0036] As a further preferred embodiment of this utility model, the supporting panel 11 is preferably a large C-shaped steel plate as shown in the figure, and the receiving panel 12 is a small C-shaped steel plate. The opening direction of the large C-shaped steel plate is opposite to that of the small C-shaped steel plate. One folded edge of the large C-shaped steel plate and one folded edge of the small C-shaped steel plate are joined together to form a rigid whole. Of course, the folded edges of the two can be made from the same steel plate, or the two ends of the same steel plate can be welded to the corresponding folded edges respectively. More preferably, the large C-shaped steel plate and the small C-shaped steel plate are integrally formed by bending from the same steel plate. The fastening and adjusting connector 13 passes through the small C-shaped steel plate and is fixedly connected to the large C-shaped steel plate, thereby wrapping the fastening and adjusting connector 13 between the two opposing C-shaped steel plates.

[0037] like Figure 2 As shown, this utility model also provides a PVC rainwater pipe fixing system, which includes a light steel enclosure 3, a fixing structure 1, a rainwater pipe 4, and pipe clamps 5. The fixing structure 1 adopts... Figure 1 The fixed structure shown has a support panel 11 fixed to the frame 31 of the light steel enclosure 3 by self-tapping screws 6. A flexible weather-resistant gasket 7 is provided between the support panel 11 and the light steel enclosure 3. The flexible weather-resistant gasket 7 is preferably an EPDM (ethylene propylene diene monomer) weather-resistant gasket. The EPDM weather-resistant gasket ensures that the fixed structure 1 will not corrode the enclosure system due to friction or uneven stress. At the same time, it can alleviate the friction between the fixed structure 1 and the light steel enclosure system caused by the shaking of the rainwater pipe 4 when rainwater passes through it. This ensures the integrity of the light steel enclosure system and improves the overall waterproof performance. A screw 2 is connected to the fastening and adjusting connector 13. The other end of the screw 2 is threaded to the pipe clamp 5. The pipe clamp 5 is fixed in a ring shape on the outer surface of the rainwater pipe 4, tightening it, thus completing the fixation of the PVC rainwater pipe 4 and the light steel enclosure 3.

[0038] This utility model uses multiple self-tapping screws to connect the fixing structure to the light steel enclosure system. The process is exactly the same as the normal fixing of the light steel enclosure system, and will not cause any new damage to the enclosure system.

[0039] This utility model uses a long nut as a fastening and adjusting connector, which makes the fastening and adjusting connector adjustable, ensuring the straightness of the rainwater pipe 4, thereby reducing the uneven force inside the rainwater pipe 4 and causing new damage to the rainwater pipe 4.

[0040] The fixed structure itself is divided into two parts: a support panel with a fixed end and a receiving panel with a receiving end. The C-shaped structure at the fixed end makes the structure stable and changes the contact between the connector and the light steel enclosure system from point contact to surface contact, which greatly improves the firmness of the connector. The C-shaped structure at the receiving end firmly wraps the long nut, making the screw and nut form a steel-like connection structure. The screw becomes a bending member to improve the connection stability between the screw and the pipe clamp and increase the service life of the entire node.

[0041] Any aspects not described herein are applicable to the prior art.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
