Description

Technical Field

[0001] This utility model relates to a hanger rod connector for construction, and more particularly to a metal-plastic composite thermal bridge-free support connector for hangers. Background Technology

[0002] Currently, commonly used zero-carbon and inverted-type buildings require a concrete layer as the wall and ceiling framework. Undoubtedly, this framework has a significant capacity for heat storage and dissipation. However, existing walls and ceilings often require numerous hanging components, which must be fixed to the framework using supporting connectors. These connectors are typically made of metal with excellent energy transfer properties. The heat dissipation and absorption by these metal connectors from the framework significantly increases energy consumption for cooling and heating. Given the increasingly unbearable global warming caused by the overexploitation of mineral resources, innovation in building energy-saving technologies has become extremely urgent. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects of the prior art and provide a metal-plastic composite thermal bridge-free support connector for a hanger.

[0004] To achieve the above objectives, the present invention provides a metal-plastic composite thermal bridge-free support connector for hangers. Its key feature is an organic rigid material base for fixing to an indoor ceiling or wall concrete slab using at least three circumferentially distributed fasteners. The organic rigid material base has a central blind hole for securing a nut, which is used to fasten the hanger rod that passes through the central blind hole for vertical or lateral load-bearing. The organic rigid material base has nail holes through which the nail shanks pass, nail hole recesses for the nail heads to penetrate, and organic material caps that seal the nail hole recesses and nail heads. The organic rigid material base is preferably a rigid plastic base. The organic rigid material base for fixing to an indoor ceiling or wall concrete slab using at least three circumferentially distributed fasteners provides significantly better stable support performance compared to using two or fewer fasteners. The organic rigid material base features a central blind hole for securing a nut on its front side. This nut is used to fasten a hanger rod that passes through the central blind hole for vertical or horizontal load-bearing. This design, while connecting the hanger rod, also prevents thermal bridging, avoiding heat transfer between the hanger rod and the fastening screw. The organic rigid material base includes a nail hole for the fastening screw rod to pass through, a nail hole recess for the nail head to penetrate, and an organic material cap to seal the nail hole recess and nail head. This design ensures the strong bond between the fastening screw and the organic rigid material base while preventing heat transfer between the nail head and the indoor air. It offers the advantages of ensuring support strength, preventing thermal bridging, avoiding increased energy consumption for cooling and heating within the building, and facilitating installation and use.

[0005] As an optimization, the lifting rod is a threaded rod with an external thread at the base and a limiting member at the end. The limiting member at the end can provide external limiting during lateral support and lower limiting during vertical lifting support.

[0006] As an optimization, end-mounted limiting components include hooks, end rings, end plates, or end balls. Hooks are used for hanging at the lower end, end rings are used for tying or hooking at the lower end, and hooks, end rings, end plates, or end balls can all be used for external end limiting during lateral support. Hooks, end rings, or end plates can also be used for hand-screwing and tightening the boom.

[0007] As an optimization, the nut is a hexagonal nut or a nut with an outer peripheral extension. Nuts with an outer peripheral extension can significantly improve the fixing strength of the nut within the organic rigid material base.

[0008] As an optimization, the peripheral extension is a base plate extending from the outer periphery of the nut base, which significantly improves the support strength of the organic rigid material base for the nut; or it is a radial arm extending from the outer periphery of the nut, which significantly improves the support and fixing strength of the organic rigid material base for the nut.

[0009] As an optimization, the radial arm is connected to an interconnecting ring concentric with the circle containing the nut. This significantly improves the support and fixing strength of the organic rigid material base for the nut.

[0010] As an optimization, the radial arm extends from the middle or base of the nut's outer periphery, and the nut's outer periphery is provided with axial reinforcing ribs, or circumferential reinforcing ribs, or axial and circumferential reinforcing ribs connecting to the base of the radial arm. This further significantly improves the support and fixing strength of the organic rigid material base for the nut.

[0011] As an optimization, the fastening nails can be expansion screws or nails. Expansion screws can be ordinary expansion screws where a hole is drilled, a plastic or metal expansion cap is inserted, and then the screw is screwed in. Alternatively, they can be high-strength expansion screws where a hole is drilled, an expansion metal sleeve and nut are inserted, and then the bolt is screwed in. Nails are suitable for drilling-free installation on walls, which is faster, and when driven into the concrete core of the wall, the lateral support strength is also guaranteed.

[0012] As an optimization, the nail hole recess is provided with an adhesive before or after the fastening nail is inserted, or both. The adhesive is preferably a nail-free adhesive, which can significantly improve the nailing strength of the organic rigid material base. The organic rigid material base is triangular, with a nail hole through which a fastening nail shank passes in each triangular part. This saves base material and fastening nail installation costs while ensuring support strength. The triangle is preferably a narrow-shouldered triangle, which is more conducive to material conservation.

[0013] As an optimization, an outer circumferential reinforcing rib and a hole ring reinforcing rib surrounding the nail hole are provided behind the organic rigid material base, as well as reinforcing ribs connecting the outer circumferential reinforcing rib and the hole ring reinforcing rib. This can improve the adhesion ability of the organic rigid material base to the slide and also help improve the overall structural strength. Alternatively, a raised grid or densely packed protrusions can be provided behind the organic rigid material base to enhance the frictional adhesion of the contact surface, which is beneficial to improving the adhesion ability of the organic rigid material base to the slide.

[0014] After adopting the above technical solution, the metal-plastic composite thermal bridge-free support connector of the hanger of this utility model has the advantages of ensuring support strength, blocking thermal bridges, avoiding increasing the energy consumption for cooling and heating in the building, and being convenient to install and use.

Detailed Implementation

[0016] Example 1, as Figure 1-4As shown, the metal-plastic composite thermal bridge-free support connector of this utility model is an organic rigid material base 1 used to fix the hanger rod to the concrete skeleton layer 10 of the wall (or the concrete skeleton layer of the indoor ceiling) by at least three circumferentially distributed fastening nails 3. The front of the organic rigid material base 1 has a central blind hole for the inner fastening nut 2, which is used to screw the hanger rod 21, which passes through the central blind hole for vertical or horizontal load bearing. The organic rigid material base 1 has nail holes 30 through which the nail shanks of the fastening nails 3 pass, nail hole recesses for the nail heads of the fastening nails 3 to penetrate, and organic material caps 4 that seal the nail hole recesses and nail heads. The organic rigid material base is preferably a rigid plastic base. The organic rigid material base used to fix the hanger rod to the concrete skeleton layer of the indoor ceiling or wall by at least three circumferentially distributed fastening nails has much better stable support performance compared to using two or fewer nails. The organic rigid material base features a central blind hole for securing a nut on its front side. This nut is used to fasten a hanger rod that passes through the central blind hole for vertical or horizontal load-bearing. This design, while connecting the hanger rod, also prevents thermal bridging, avoiding heat transfer between the hanger rod and the fastening screw. The organic rigid material base includes a nail hole for the fastening screw rod to pass through, a nail hole recess for the nail head to penetrate, and an organic material cap to seal the nail hole recess and nail head. This design ensures the strong bond between the fastening screw and the organic rigid material base while preventing heat transfer between the nail head and the indoor air. It offers the advantages of ensuring support strength, preventing thermal bridging, avoiding increased energy consumption for cooling and heating within the building, and facilitating installation and use.

[0017] Specifically, the lifting rod 21 is a threaded rod with an external thread at the base and a limiting component at the end. The limiting component at the end is a hook, end ring, end plate, or end ball. The nut 2 is a hexagonal nut. The fastening nail 3 is an expansion screw, or it can be a nail. The expansion screw can be a common expansion screw where a plastic or metal expansion cap is inserted after drilling a hole, and then the screw is screwed in; or it can be a high-strength expansion screw where an expansion metal sleeve and nut are inserted after drilling a hole, and then the bolt is screwed in.

[0018] Specifically, the organic rigid material base 1 is a narrow-waisted triangle, and each of the triangular portions of the narrow-waisted triangle has a nail hole 30 through which a fastening nail 3 passes. Preferably, the nail hole recess is provided with adhesive before or after the fastening nail is inserted, or both before and after.

[0019] Specifically, the organic rigid material base 1 is provided with an outer peripheral ring reinforcing rib, a hole ring reinforcing rib surrounding the nail hole, and a reinforcing rib 11 connecting the outer peripheral ring reinforcing rib and the hole ring reinforcing rib; or the organic rigid material base is provided with a raised grid or densely distributed protrusions to enhance the frictional adhesion of the contact surface.

[0020] Example 2, as Figure 5As shown, the difference between the metal-plastic composite thermal bridge-free support connector of this utility model and the first embodiment described above is that the nut 2 is a hexagonal nut with an outer peripheral extension. The outer peripheral extension is a base plate 20 extending from the outer periphery of the base of the nut 2.

[0021] Example 3, as Figure 6 As shown, the difference between the metal-plastic composite thermal bridge-free support connector of this utility model and the above-described embodiment two is that the outer peripheral extension is a radial arm 26 extending from the outer periphery of the nut 2. Preferably, the radial arm is connected to an interconnecting ring concentric with the circle containing the nut. More preferably, the radial arm extends from the middle or base of the outer periphery of the nut, and the outer periphery of the nut is provided with axial reinforcing ribs, or circumferential reinforcing ribs, or axial and circumferential reinforcing ribs connecting the base of the radial arm.

[0022] In summary, the metal-plastic composite thermal bridge-free support connector of this utility model has the advantages of ensuring support strength, blocking thermal bridges, avoiding increased energy consumption for cooling and heating in buildings, and being easy to install and use.
