Addressing the problem of thermal bridging in existing metal rainwater pipe supports, this support replaces the solid support with a hollow, U-shaped structure with a circular cross-section, filled with thermal insulation material. A connecting pipe is located at the top, its inner wall also insulated. The threaded rod at the bottom of the pipe clamp connects to the connecting pipe, and a suitable fastener is fitted at the connection point. Most components are made of thermal insulation material. A through-hole is provided on one side of the support leg, allowing the thermal insulation material to wrap around the leg, reducing heat transfer with the wall.

Description

Technical Field

[0001] This utility model relates to the field of rainwater pipe support technology, specifically to a rainwater pipe support for an exterior wall thermal break bridge in an ultra-low energy consumption building. Background Technology

[0002] Ultra-low energy buildings refer to a type of building that, while meeting indoor environmental quality requirements, achieves significantly lower energy consumption levels than conventional buildings through a series of technological measures, including efficient thermal insulation systems, airtight building envelopes, efficient fresh air heat recovery systems, and the utilization of renewable energy. Their exterior walls typically employ ultra-high performance thermal insulation systems with a significantly increased insulation layer thickness. Common materials include high-efficiency insulation materials such as rock wool, polystyrene boards, and polyurethane. For example, some advanced ultra-low energy buildings can have an exterior wall insulation layer thickness of approximately 30 centimeters. Simultaneously, the construction requirements for the airtight layer of the exterior walls are extremely stringent to minimize air leakage and prevent heat loss through gaps.

[0003] The installation of rainwater pipe supports requires nailing them directly into the base wall through the insulation layer. Since rainwater pipe supports are usually made of metal, they are prone to thermal bridging, causing heat loss and poor overall building insulation performance. Furthermore, existing thermal break rainwater pipe supports require multiple parts for complex installation. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned existing problems.

[0005] To achieve the above objectives, the technical approach adopted by this utility model to solve its technical problem is as follows: the solid support is replaced with a hollow Z-shaped structure with a circular cross-section. The circular design facilitates uniform force distribution, the hollow structure reduces the heat conduction path, and the Z-shape makes the legs stable, ensuring solid support. The hollow structure is filled with heat insulation material, and a connecting pipe is opened at the top of the support. The inner wall of the connecting pipe is also provided with heat insulation material. A threaded rod is provided at the bottom of the pipe clamp. The threaded pipe is inserted into the connecting pipe and contacts the heat insulation material. The two are connected by threads to inhibit heat conduction through the support.

[0006] Although the initial research and manufacturing costs of hollow-core sandwich-type supports are slightly higher, they can save buildings significant expenses in the long term from the perspective of operation and maintenance and energy loss. Solid supports are significantly affected by changes in ambient temperature; during high temperatures, heat is rapidly conducted and accumulated inside the support, causing the material to expand; during low temperatures, it contracts drastically. Frequent cycles of thermal expansion and contraction can cause microscopic cracks inside the support, weakening its overall strength over time. The hollow, U-shaped structure of the hollow-core support reduces heat conduction, and the internal insulation material almost completely blocks heat transfer. Even with sudden changes in external temperature, the internal temperature of the support can remain relatively stable, preventing significant thermal expansion and contraction, thus fundamentally avoiding temperature-induced structural deformation and ensuring long-term stability.

[0007] Meanwhile, a through-hole is opened on one side of the support leg so that the heat insulation material inside the bracket extends out along the through-hole to wrap the support leg at the bottom of the bracket, separating the bracket from the wall and reducing heat transfer.

[0008] A fixing piece is sleeved at the connection between the connecting pipe and the threaded rod. The through-holes on both sides thereof are respectively adapted to the outer diameters of the two, preventing the threaded connection from loosening due to external force vibration, temperature change or rainwater invasion, enabling it to be threadedly connected to the connecting pipe, and using its own heat insulation property to strengthen the wall strength of the connecting pipe and prevent cracks from appearing.

[0009] To achieve the above object, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0010] Design a rainwater bracket with a broken heat bridge for the exterior wall of an ultra-low energy consumption building. The specific solution is as follows:

[0011] A rainwater pipe bracket with a broken heat bridge for the exterior wall of an ultra-low energy consumption building includes a bracket body and a pipe hoop arranged above the bracket body. The interior of the bracket body is a hollow structure and is filled with a heat insulation material; a connecting pipe is provided at the top of the bracket body, and the inner wall of the connecting pipe is lined with a heat insulation material; there are support legs at the bottom of the bracket body, and a through-hole is opened on one side thereof, and the internal heat insulation material extends out through the through-hole to wrap the support legs.

[0012] Further, the bracket body is in a U-shape, and the cross-section of the hollow structure is circular.

[0013] Further, a threaded rod is provided at the bottom of the pipe hoop, and the connecting pipe is threadedly connected to the threaded rod for adjusting the distance between the pipe hoop and the bracket body.

[0014] Further, a fixing piece is sleeved at the connection between the connecting pipe and the threaded rod, and the through-holes on both sides of the fixing piece are respectively adapted to the outer diameters of the connecting pipe and the threaded rod.

[0015] Further, the fixing piece is made of a heat insulation material.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By adopting a hollow structure and filling it with a heat insulation material, the heat conduction path is fundamentally reduced, and the heat transfer in the bracket is greatly blocked. The inner wall of the connecting pipe at the top of the bracket is also provided with a heat insulation material, which cooperates with the heat insulation material extending out of the through-hole at the support leg to wrap the support leg, comprehensively isolating the heat transfer between the wall and the bracket, and the device is integrally formed for convenient installation.

[0018] 2. The pipe clamp and bracket are connected by a heat-insulated threaded connection, which can adjust the distance between the pipe clamp and the bracket while inhibiting heat conduction. The fasteners fitted at the connection are adapted to the outer diameter of the connecting pipe and the threaded rod, which not only strengthens the connection and prevents loosening caused by external vibration, temperature changes, and rainwater intrusion, but also strengthens the pipe wall by tightly connecting with the connecting pipe, avoiding cracks. Overall, the stability and durability of the rainwater pipe installation system are improved. Attached Figure Description

[0030] refer to Figure 1-7This utility model provides a rainwater pipe support for thermal break bridges on the exterior wall of an ultra-low energy consumption building, including a support body 10 and a pipe clamp 20 disposed above the support body 10.

[0031] In practical implementation, the support body 10 has an internally hollow, Z-shaped structure made of stainless steel, which has good corrosion resistance and strength. The overall Z-shaped structure has an upper horizontal section length of 50-70mm, two vertical sections a height of 110-130mm, and two outwardly folded legs 12 with side lengths of 60-80mm. The legs 12 extend to both sides for fixing to the base wall surface, and their cross-section is circular. This circular design mechanically achieves uniform force distribution, effectively dispersing loads from all directions. Furthermore, the internal cavity of the support body 10 is filled with thermal insulation materials such as polystyrene foam board or polyurethane foam.

[0032] The bottom of the support leg 12 has a through hole 120 so that the internal heat insulation material can extend outward to wrap around the bottom of the support leg 12 and block the heat transfer between the support body 10 and the base wall.

[0033] In practice, a connecting pipe 11 is provided at the top of the support body 10. This connecting pipe is made of the same stainless steel as the support body, with a length of 30-50mm. Its inner diameter is slightly larger than the outer diameter of the threaded rod 21 at the bottom of the clamp 20, typically by 10-20mm. The connecting pipe 11 is internally connected to the support body 10, allowing the insulation material to be laid along the inner wall of the connecting pipe 11 to form a cavity. The cavity contains threads that mate with the threaded rod 21. The outer side of the connecting pipe 11 also has threads for mate with the fixing component 30.

[0034] In practice, the pipe clamp 20 is a common rainwater pipe clamp, usually made of stainless steel or galvanized steel, which has a certain degree of flexibility and strength. It usually has openings on both sides, which are bent outward to form a structure similar to a "lip". Adjustable bolts are installed on the openings to tighten them to accommodate rainwater pipes of different sizes.

[0035] A threaded rod 21 is integrally welded to the bottom of the pipe clamp 20. The threaded rod 21 is 30-40mm long and its diameter matches the inner diameter of the connecting pipe at the top of the support body. The threaded rod 21 has regular threads machined all around it for threaded connection with the connecting pipe 11 and for adjusting the distance between the pipe clamp 20 and the support body 10.

[0036] A fixing member 30 is fitted at the connection between the connecting pipe 11 and the threaded rod 21. The through holes on both sides of the fixing member 30 are adapted to the outer diameters of the connecting pipe 11 and the threaded rod 21, respectively.

[0037] In practice, the fastener 30 is made of heat-insulating material and is cylindrical in shape. The through holes on both sides are adapted to the outer diameters of the connecting pipe 11 and the threaded rod 21, respectively, and the side adapted to the connecting pipe 11 is provided with a thread to cooperate with the connecting pipe 11.

[0038] In specific operation, a groove corresponding to the bracket body is set in the insulation layer, the side of the bottom of the support leg 12 with the heat insulation material is brought into contact with the foundation wall and fixed with expansion bolts. At this time, the insulation layer is wrapped around the outside of the support leg 12, and only the connecting pipe 11 is exposed. The connection length of the connecting pipe 11 and the threaded rod 21 is adjusted according to the thickness of the insulation layer and the outer surface. Then, the rainwater pipe is set in the pipe clamp 20.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
