Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, and in particular to a connecting component for energy-saving buildings and a connecting structure for the eaves of buildings. Background Technology

[0002] Currently, building energy conservation is one of the core directions of development in the construction industry. It is not only related to the efficient use of energy resources, but also closely related to environmental protection, improved living comfort, and long-term economic benefits. With the continuous improvement of building energy conservation standards, the optimization of the thermal insulation performance of building exterior walls, as a key component of building insulation, has become a focus of industry research. However, design flaws in building connectors within existing building exterior wall systems have become a significant bottleneck restricting the overall energy-saving effect of buildings.

[0003] Currently, the connection between building exterior walls and external components (such as decorative panels and insulation layer fixing structures) generally adopts a direct anchor connection method. This involves using metal connectors that penetrate the exterior wall insulation layer, with one end fixed to the main building structure and the other end connected to the external component. However, metal has a high thermal conductivity coefficient. In this direct connection structure, the metal connectors form a "thermal bridge" running through the building exterior wall. Heat (or cold) from the external environment can be quickly conducted to the inside of the exterior wall through the metal connectors, and then transferred to the interior space. This process not only leads to a decrease in the stability of the building's indoor temperature, forcing air conditioning, heating, and other indoor environmental regulation equipment to operate at high loads for extended periods, significantly increasing building energy consumption (statistics show that energy losses caused by such connector "thermal bridges" account for 8%-15% of total building energy consumption), but also weakens the designed insulation effect of the building's exterior wall insulation layer, making it difficult for the overall building energy-saving performance to meet the preset standards, which is seriously inconsistent with current building energy-saving requirements.

[0004] Furthermore, current optimizations of building energy conservation primarily focus on macro-level aspects such as upgrading external wall insulation materials and improving the overall design of external wall structures, while generally neglecting the energy-saving issues of building connectors—a seemingly minor component. On the one hand, while the heat conduction loss of a single metal connector may appear limited, the number of connectors used in a building can typically reach hundreds or even thousands. The cumulative energy loss caused by the "thermal bridge" effect of a large number of connectors is considerable, becoming a hidden energy consumption loophole in the building energy conservation system that is difficult to ignore. On the other hand, as the construction industry deepens its implementation of sustainable development concepts, the energy conservation requirements throughout the building's entire life cycle are becoming increasingly stringent. The heat conduction defects of existing building connectors will lead to continuous additional energy consumption during long-term use, contradicting the development goals of energy conservation throughout the building's entire life cycle and failing to meet the current construction industry's demand for green, low-carbon, and highly efficient energy-saving buildings.

[0005] In summary, the existing building connectors, which use anchors to directly connect to the building's exterior walls, create "thermal bridges" due to the high thermal conductivity of the metal material. This leads to increased building energy consumption and reduced energy-saving effects. Furthermore, the industry's current technology does not pay enough attention to this issue and lacks effective solutions to address the "thermal bridge" defects in building connectors. There is an urgent need for a building connector structure or design that can block heat conduction through the connectors and improve the overall energy-saving performance of the building, in order to fill the gap in existing technology and meet the needs of building energy conservation development. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a connecting component for energy-saving buildings and a connecting structure for the eaves of buildings, so as to solve the technical problem that existing metal connectors form a "thermal bridge" through the exterior wall of the building, which transfers heat and leads to increased building energy consumption.

[0007] To achieve the objectives of this utility model, the technical solution adopted by this utility model is as follows: Design a connecting component for an energy-efficient building, including a building wall, a connecting anchor connected to the building wall, and a connecting steel plate fixed to the building wall via the connecting anchor. An outwardly extending cantilevered steel beam is fixed to the connecting steel plate, and the front section of the steel beam is connected to a steel keel connector extending horizontally along the length of the building wall. A heat insulation pad is sandwiched between the connecting steel plate and the building wall. A heat insulation sleeve is fitted between the connecting anchor and the connecting steel plate. The outer side of the building wall is covered with an insulation layer, which completely wraps and covers the end of the connecting anchor located on the outer side of the building wall.

[0008] Both the heat insulation pad and the heat insulation sleeve are rigid polyurethane boards.

[0009] Both the connecting steel plate and the heat insulation pad have corresponding through holes for the heat insulation sleeve to pass through. The heat insulation sleeve is inserted into the through holes, and both ends of the heat insulation sleeve are respectively attached to the outer wall of the connecting anchor and the inner wall of the through hole.

[0010] One end of the connecting anchor is inserted into the building wall and fixed to the building wall. The other end passes through the heat insulation sleeve and the connecting steel plate in sequence and then extends out. The extended end is threaded with a nut. The nut is pressed against the side of the connecting steel plate away from the heat insulation pad to fix the connecting steel plate.

[0011] The same steel keel connector is connected to the connecting steel plate by at least two steel beams, and the at least two steel beams are spaced apart along the length of the steel keel connector.

[0012] The number of steel beams fixed on the same connecting steel plate is at least two, and the at least two steel beams are arranged parallel to each other and spaced apart along the length direction of the connecting steel plate.

[0013] Furthermore, this utility model also designs a connection structure for the eaves of a building, including an aluminum eaves, which includes the connection components of the energy-saving building as described above. The aluminum eaves are fixedly connected to the steel keel connector in the connection components of the energy-saving building through fasteners, and the aluminum eaves extend along the top edge of the building wall.

[0014] The building wall is connected to a roof at the top. The waterproof layer of the roof extends towards the aluminum eaves and covers the upper surface of the aluminum eaves. The connection between the waterproof layer and the aluminum eaves is sealed.

[0015] The beneficial effects of this utility model are as follows: This invention addresses the technical shortcomings of existing building connectors, which create thermal bridges by directly connecting metal components to the exterior wall, leading to increased building energy consumption and poor energy-saving effects. By optimizing the structural design of the building connectors, it effectively blocks thermal bridges, significantly reducing building energy consumption. Secondly, it avoids the metal connectors directly penetrating the building's exterior wall insulation layer to form heat conduction channels, significantly reducing the efficiency of external heat (or cold) transfer to the interior, improving indoor environmental stability, and enhancing the living and usage experience. Furthermore, by blocking thermal bridges in the connectors, this invention reduces fluctuations in indoor temperature caused by changes in the external environment, keeping indoor temperature and humidity within a more stable range. In summer, it reduces the cooling load of indoor air conditioning, and in winter, it reduces the energy consumption of the heating system, avoiding problems such as excessive local temperature differences and condensation. This significantly improves the living comfort and ease of use of the building, meeting users' demands for a high-quality building environment.

[0016] Furthermore, the structure designed in this utility model is highly adaptable and easy to promote and apply. The connector design of this utility model can be compatible with the existing building exterior wall construction process and the connection requirements of external components (such as decorative panels and insulation layers). It does not require large-scale modification of the main building structure, has low construction difficulty and controllable cost, and can be widely used in different scenarios such as civil buildings, public buildings, and industrial buildings, as well as building projects in different climate zones such as severe cold, hot summers and cold winters. It has strong practicality and promotion value and can promote the improvement of the overall energy-saving level of the building industry. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A connecting component for an energy-efficient building, see [link / reference] Figure 1 , Figure 2 .

[0019] It includes a building wall 1, a connecting anchor 2 connected to the building wall 1, and a connecting steel plate 4 fixed to the building wall 1 by the connecting anchor 2. The connecting steel plate 4 is made of Q235 low carbon steel and has high strength (yield strength ≥235MPa). It is used to bear the load of the steel beam 7 and transfer it to the building wall 1. It has perforations that are compatible with the heat insulation sleeve 6 to ensure that the heat insulation sleeve 6 can be stably penetrated.

[0020] A cantilevered steel beam 7 extending outwards is fixed on the connecting steel plate 4. The front end of the steel beam 7 is connected to a steel keel connector 8 that extends horizontally and along the length of the building wall 1. A heat insulation pad 3 is sandwiched between the connecting steel plate 4 and the building wall 1. The heat insulation pad 3 is sized to match the connecting steel plate 4 and fits between the connecting steel plate 4 and the building wall 1. A through hole corresponding to the connecting anchor 2 is opened on it to ensure that the connecting anchor 2 can pass through without metal contact.

[0021] Meanwhile, a heat insulation sleeve 5 is fitted between the connecting anchor 2 and the connecting steel plate 4. The heat insulation sleeve 5 has a cylindrical structure, with an inner diameter that matches the outer diameter of the connecting anchor 2 and an outer diameter that matches the perforation diameter of the connecting steel plate 4 and the heat insulation pad 3. Its length is equal to the sum of the thickness of the connecting steel plate 4 and the thickness of the heat insulation pad 3, ensuring that the connecting anchor 2 and the connecting steel plate 4 can be completely isolated after penetration. Both the heat insulation pad 3 and the heat insulation sleeve 5 are made of rigid polyurethane board, which uses its low thermal conductivity (≤0.024W / (m・K)) to block heat transfer, while having sufficient compressive strength (≥250kPa) to ensure the stability of the connection structure. In this embodiment, both the connecting steel plate 4 and the heat insulation pad 3 are provided with corresponding through holes for the heat insulation sleeve to pass through. The heat insulation sleeve 5 is inserted into the through holes, and the two ends of the heat insulation sleeve 5 are respectively attached to the outer wall of the connecting anchor 2 and the inner wall of the through hole. This design achieves the fixation of the connecting steel plate 4 on the building wall, and the heat insulation pad and heat insulation sleeve prevent direct metal contact between the connecting steel plate, the connecting anchor and the building wall. In this embodiment, the outer side of the building wall 1 is covered with an insulation layer 6, and the insulation layer 6 completely covers the end of the connecting anchor 2 located on the outer side of the building wall 1, preventing the connecting anchor 2 from being exposed and forming a heat conduction channel. In this embodiment, the insulation layer 6 is made of extruded polystyrene board with a thermal conductivity ≤0.030W / (m・K) and a water absorption rate ≤1.5%. It covers the outer side of the building wall 1, completely covering the outer end of the connecting anchor, and the gap between it and the steel beam 7 is filled with polyurethane foam (thermal conductivity ≤0.033W / (m・K)), forming a continuous and gapless insulation structure to block heat conduction from the connecting anchor 2 or the gap.

[0022] In this embodiment, the same steel keel connector 8 is connected to the connecting steel plate 4 through two steel beams 7, and the two steel beams 7 are spaced apart along the length direction of the steel keel connector 8. The steel beams 7 are fixed on the connecting steel plate 4 and cantilevered outward. The steel keel connector 8 is connected to the front section of the steel beam 7 to form an outwardly extending load-bearing structure for subsequent connection of external building components (such as eaves and decorative panels). In this embodiment, there are two steel beams 7 fixed on the same connecting steel plate 4, and the two steel beams 4 are arranged parallel to each other along the length direction of the connecting steel plate 4 to distribute the load.

[0023] Example 2, a connection structure for the eaves of a building, see [reference] Figure 1 , Figure 2 .

[0024] It includes an aluminum eaves 11, the surface of which is treated with fluorocarbon coating (coating thickness ≥40μm), with a salt spray resistance of ≥1000h, suitable for long-term outdoor use, and preventing rust and fading. The aluminum eaves 11 are covered with roof tiles 12. It also includes connecting components for energy-saving buildings as described in Example 1. The aluminum eaves 11 are fixedly connected to the steel keel connectors 8 in the connecting components of the energy-saving building via fasteners 9, and the aluminum eaves 11 extends along the top edge of the building wall. Simultaneously, a roof is connected to the top of the building wall, and the waterproof layer 10 of the roof extends towards the aluminum eaves, covering the upper surface of the aluminum eaves. The connection between the waterproof layer 10 and the aluminum eaves 11 is sealed to prevent rainwater infiltration.
