Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a drainage pipe structure that spans structural joints. Background Technology

[0002] Expansion joints and settlement joints are two common structural joints in building construction. Their main function is to reduce the risk of damage to buildings caused by changes in the external environment or internal stress. They are widely used in places such as between the main building and the podium, and between the main building and the connecting corridor.

[0003] Taking a high-rise building connecting corridor as an example, a connecting corridor is a horizontal passageway used to connect two independent buildings. It is typically located on higher floors of a high-rise building and is suspended at the bottom, with structural joints on both sides where it intersects with the main building. Due to the height of the connecting corridor and its suspended bottom, if the rainwater pipes on the corridor roof adopt a vertical drainage method, they need to be laid along the outer side of the building's exterior walls. When the main building undergoes thermal expansion and contraction or uneven settlement, the relative displacement on both sides of the structural joints will cause the drainage pipes laid on them to bear significant deformation stress. If the drainage system is not designed properly, it can easily cause pipe deformation, breakage, or even detachment, affecting drainage function and creating safety hazards.

[0004] Therefore, when a pipe crosses a structural joint, a drainage pipe structure that crosses the structural joint is required, which has an effective compensation mechanism to cope with structural deformation. This ensures that rainwater from the connecting corridor can be discharged smoothly through the pipe, and also ensures that the drainage pipe will not deform or break when the building experiences thermal expansion and contraction or uneven settlement. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a drainage pipe structure that spans structural joints, in view of the above-mentioned problems.

[0006] The technical solution adopted by this utility model is: a drainage pipe structure spanning a structural joint, used to divert accumulated water from the building structure located inside the structural joint to the drainage system of the building structure located outside the structural joint, comprising:

[0007] The first drainage structure is arranged horizontally below the structural joint to span the structural joint. The inlet is located below the drainage outlet of the building structure inside the structural joint, which can drain the water inside the structural joint. The outlet extends to the outer wall of the building structure outside the structural joint.

[0008] The second drainage structure is arranged vertically on the outer wall of the building structure outside the structural joint. Its input end is located below the output end of the first drainage structure, and its output end can connect to the drainage system. The input end of the second drainage structure and the output end of the first drainage structure are offset by a predetermined distance in the horizontal direction to accommodate the expansion and contraction distance of the structural joint.

[0009] Using the aforementioned technical means, a first drainage structure is arranged horizontally below the structural joint, allowing it to span the joint. One end of the first drainage structure receives accumulated water from the building structure inside the joint, while the other end transports the water to a second drainage structure. The vertically arranged second drainage structure then guides the water into the drainage system. Furthermore, the output end of the first drainage structure and the input end of the second drainage structure are staggered, allowing the drainage pipe structure to adapt to relative displacement caused by the structural joint.

[0010] In some embodiments, the first drainage structure includes a first drainage riser, a first drainage horizontal branch pipe, a first drainage pipe support, and a drainage diversion pipe. The first drainage horizontal branch pipe is laid below the structural joint via the first drainage pipe support. The first drainage horizontal branch pipe is arranged horizontally to cross the structural joint. The first end of the first drainage horizontal branch pipe is connected to a vertically arranged first drainage riser. The end of the first drainage riser away from the first drainage horizontal branch pipe can collect accumulated water. The second end of the first drainage horizontal branch pipe is connected to a vertically arranged drainage diversion pipe. The end of the drainage diversion pipe away from the first drainage horizontal branch pipe corresponds to the input end of the second drainage structure. The drainage diversion pipe can guide the collected accumulated water to the second drainage structure.

[0011] In some embodiments, the second drainage structure includes a receiving drainage hopper, a second drainage riser, and a second drainage pipe support. The second drainage riser is installed on the outer wall of the building structure outside the structural joint via the second drainage pipe support. The second drainage riser is arranged vertically. The first end of the second drainage riser is connected to the receiving drainage hopper, which is located below the output end of the first drainage structure. The second end of the second drainage riser is used to connect to the drainage system.

[0012] In some embodiments, the output end of the first drainage structure is located at the center of the receiving drainage bucket, the width direction of the receiving drainage bucket corresponds to the expansion and contraction direction of the structural joint, and the preset width of the receiving drainage bucket is adapted to the expansion and contraction width of the structural joint.

[0013] In some embodiments, the receiving and draining bucket has a length of 300 mm, a width of 200 mm, and a depth of 200 mm. The output end of the first drainage structure extends at least partially into the receiving and draining bucket. The center of the output end of the first drainage structure is 100 mm from the long side of the receiving and draining bucket, and the center of the output end of the first drainage structure is 150 mm from the short side.

[0014] The beneficial effects of this utility model are:

[0015] 1. By horizontally arranging the first drainage structure below the structural joint, spanning the joint, and reserving horizontal and vertical offset distances between the outlet end and the second drainage structure, the first drainage structure can move with the inner structure when the building experiences thermal expansion and contraction or uneven settlement, without directly pulling or compressing the outer second drainage structure. This avoids the risk of pipe breakage due to deformation. Simultaneously, the water introduced by the first drainage structure can freely fall into the second drainage structure. This "disconnected" design not only provides buffer space for structural deformation, avoiding stress concentration that may result from rigid connections, but also ensures the normal drainage of accumulated water.

[0024] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0025] Combination Figures 1 to 3As shown, this embodiment is a drainage pipe structure spanning a structural joint, used to divert accumulated water from the building structure located inside the structural joint 9 to the drainage system of the building structure located outside the structural joint 10. It includes a first drainage structure and a second drainage structure. The first drainage structure is horizontally arranged at the bottom of the building structure inside the structural joint 9, and is located below the structural joint 8, spanning it. The input end of the first drainage structure is located below the drain outlet of the building structure inside the structural joint 9, capable of diverting accumulated water from the building structure inside the structural joint 9. The output end of the first drainage structure extends to the outer wall of the building structure outside the structural joint 10. The second drainage structure is vertically arranged on the outer wall of the building structure outside the structural joint 10. The input end of the second drainage structure is located below the output end of the first drainage structure, and the output end of the second drainage structure can connect to the drainage system. The input end of the second drainage structure and the output end of the first drainage structure are horizontally offset by a predetermined distance to accommodate the expansion and contraction of the structural joint 8.

[0026] In some embodiments, the first drainage structure includes a first drainage riser 1, a first drainage horizontal branch pipe 2, a first drainage pipe support 6, and a drainage diversion pipe 3. The first drainage horizontal branch pipe 2 is laid at the bottom of the structural beam of the building structure inside the structural joint 8 via the first drainage pipe support 6. The first drainage horizontal branch pipe 2 is located below the structural joint 8 and is arranged laterally to cross the structural joint 8 in plan view. The first end of the first drainage horizontal branch pipe 2 is connected to the vertically arranged first drainage riser 1. The end of the first drainage riser 1 away from the first drainage horizontal branch pipe 2 can collect accumulated water. The second end of the first drainage horizontal branch pipe 2 is connected to the vertically arranged drainage diversion pipe 3. The drainage diversion pipe 3 can adjust the direction of water flow. The end of the drainage diversion pipe 3 away from the first drainage horizontal branch pipe 2 corresponds to the input end of the second drainage structure. The drainage diversion pipe 3 can guide the collected accumulated water to the second drainage structure.

[0027] Furthermore, in this embodiment, the building structure inside the structural joint 9 is provided with drainage facilities such as floor drains / rainwater hoppers, and the top of the first drainage riser 1 is located below the drainage facilities.

[0028] The first drainage horizontal branch pipe 2 serves as the drainage pipe passing under the structural joint 8, allowing the water flowing from the first drainage riser 1 to enter the drainage diversion pipe 3 via the first drainage horizontal branch pipe 2. The drainage diversion pipe 3 converts the horizontal flow direction to a vertical flow direction, facilitating connection with the second drainage structure. The first drainage horizontal branch pipe 2 is laid on the building structure inside the structural joint 9 via the first drainage pipe support 6. When the building structure shifts, it can move with the inner structure, reducing the pulling effect on the second drainage structure.

[0029] In some implementations, the second drainage structure includes a receiving drainage hopper 4, a second drainage riser 5, and a second drainage pipe support 7. The second drainage riser 5 is installed on the outer wall of the building structure outside the structural joint 10 via the second drainage pipe support 7. The second drainage riser 5 is arranged vertically. The first end of the second drainage riser 5 is connected to the receiving drainage hopper 4, which is located below the drainage turning pipe 3. The second end of the second drainage riser 5 is used to connect to the drainage system.

[0030] Furthermore, the output end of the first drainage structure is located at the center of the receiving drainage bucket 4, the width direction of the receiving drainage bucket 4 corresponds to the expansion and contraction direction of the structural joint 8, and the preset width of the receiving drainage bucket 4 is adapted to the expansion and contraction width of the structural joint 8.

[0031] The end of the drainage diversion pipe 3 is directly connected to the drainage hopper 4, which is used for drainage to improve efficiency and reduce the risk of splashing. The first and second drainage structures are not rigidly connected; instead, a certain distance is maintained to allow water to fall freely, forming a "disconnected" drainage system that is more adaptable to structural deformation. The drainage hopper 4 acts as an intermediate container between the first and second drainage structures, buffering and collecting water to prevent overflow. The second drainage structure is installed on the building structure outside the structural joint 10 via independent supports, separate from the first drainage structure to avoid mutual interference and enhance system stability. Simultaneously, the output end of the drainage diversion pipe 3 is located at the center of the drainage hopper 4, ensuring even water flow into the hopper and preventing overflow due to uneven flow. By adjusting the size of the drainage hopper 4 according to the expansion and contraction distance of the structural joint 8, even if there is some displacement on both sides of the structural joint 8, the width of the drainage hopper is sufficient to cover the possible deviation range, ensuring drainage safety.

[0032] Furthermore, the receiving drain hopper 4 has a length of 300mm, a width of 200mm, and a depth of 200mm, and the drain diversion pipe 3 extends at least partially into the receiving drain hopper 4. Specifically, the drain diversion pipe 3 extends into the top of the receiving drain hopper 4 by at least 50mm, the drain diversion pipe 3 is at least 100mm from the bottom of the receiving drain hopper 4, the center of the drain diversion pipe 3 is 100mm from the long side of the receiving drain hopper 4, and the center of the drain diversion pipe 3 is 150mm from the short side.

[0033] Furthermore, in this embodiment, the diameters of the first drainage riser 1, the first drainage horizontal branch pipe 2, and the second drainage riser 5 are all DN100mm.

[0034] The implementation principle of a drainage pipe structure that spans a structural joint in this embodiment is as follows:

[0035] In this embodiment, the water flow originates from the roof or terrace area of ​​the building structure inside the structural joint 9, such as rainwater from the roof of a connecting corridor or drainage from a floor drain. First, the water is collected and discharged through a drain outlet (such as a rainwater hopper or floor drain). The accumulated water falls vertically from the drain outlet to the first drainage riser 1, which directs the water flow to the first drainage horizontal branch pipe 2. The first drainage horizontal branch pipe 2 crosses the structural joint 8 laterally, transporting the water flow to the outside of the structural joint 10. The end of the first drainage horizontal branch pipe 2 is connected to a drainage diversion pipe 3, which converts the horizontal flow direction to a vertical flow direction.

[0036] The output end of the drainage diversion pipe 3 extends a certain distance above the receiving drainage hopper 4, allowing water to fall freely into the hopper. The output end of the drainage diversion pipe 3 is located at the center of the drainage hopper, ensuring even water flow and preventing deviation or splashing. The receiving drainage hopper 4 acts as a buffer and collector, preventing water from directly impacting the second drainage riser 5. The second drainage riser 5 is vertically arranged along the building's exterior wall, capable of transporting water to the outdoor drainage system (such as rainwater wells or drainage networks).

[0037] The main pipe of the first drainage structure is fixed to the building structure inside the structural joint 9 via the first drainage pipe support 6, and the first drainage structure is mainly responsible for leading the accumulated water on the inner side of the structure to the outer side 10 of the structural joint. The main pipe of the second drainage structure is fixed to the building structure outside the structural joint 10 via the second drainage pipe support 7, and the second drainage structure is mainly responsible for receiving the output of the first drainage structure and finally discharging the water into the outdoor drainage system. The two systems are connected by a disconnection type, that is, a certain gap is left between the outlet of the drainage diversion pipe 3 and the receiving drainage hopper 4 to achieve flexible drainage and adapt to structural deformation. The two support systems are independent of each other to avoid stress caused by thermal expansion and contraction or settlement differences of the building through the pipes, and to prevent pipe cracking or deformation.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
