Description

Technical Field

[0001] This utility model relates to the field of thermal break technology, specifically to a thermal break connector for a main structure. Background Technology

[0002] With the increasing prominence of global energy and environmental issues, people are paying more and more attention to building energy consumption, and reducing building thermal bridges is a key design consideration. Thermal bridges are areas of high heat flow during heat exchange between a building and the outside environment. They not only increase energy consumption, but also, if the internal surface temperature falls below the dew point in winter, create a damp environment due to water vapor condensation, leading to mold and mildew growth, reducing building lifespan, and impacting health. Balconies are a critical location for thermal bridges and require insulation treatment.

[0003] With the escalation of global energy and environmental issues, building energy conservation has become a focal point, with balconies, due to their cantilevered structures, exhibiting high heat flux density and weak insulation, posing a key challenge. However, traditional thermal bridge treatments suffer from two major technical bottlenecks: First, it's difficult to coordinate thermal bridge breaking with structural stability—ordinary carbon steel anchors form a continuous heat conduction path with the concrete, resulting in thermal bridge energy consumption exceeding 20% ​​of the building's total energy consumption; simply adding insulation layers can easily lead to cracking due to insufficient shear strength in the cantilevered areas. In winter, when the surface temperature of the thermal bridge area is below the dew point, condensation and mold problems frequently occur, threatening the building's lifespan and health. Second, there are issues of inefficient construction and durability defects—existing thermally broken bridge structures rely on on-site multi-layer insulation wrapping and complex anchoring, resulting in long construction cycles and a high risk of joint leakage; metal connectors lack anti-corrosion treatment, leading to rust and expansion that damages the insulation layer after long-term exposure, requiring multiple maintenance cycles over a 50-year building lifespan, causing a surge in costs. Utility Model Content

[0004] Therefore, in order to solve the above problems, the purpose of this utility model is to provide a thermal break connector for the main structure, including an upper plate, a lower plate, a front plate, and a rear plate. The upper plate and the lower plate are arranged in parallel, and a filling gap is formed between the upper plate and the lower plate. The upper and lower ends of the front plate are respectively connected to the upper plate and the lower plate, and the upper and lower ends of the rear plate are respectively connected to the upper plate and the lower plate. Thermal insulation material is provided in the filling gap, and steel bars are inserted through the thermal insulation material. The front end of the steel bars is connected to the cantilever structure, and the rear end is connected to the floor slab.

[0005] Preferably, the reinforcing bars include upper tension bars and lower compression bars respectively disposed on the upper and lower layers of the insulation material.

[0006] Preferably, the upper pull bar is covered with carbon fiber cloth, and the carbon fiber cloth is covered with an epoxy resin adhesive layer.

[0007] Preferably, the insulation material is further provided with shear-resistant steel, which is in the shape of an "I".

[0008] Preferably, the upper plate and the lower plate are wrapped with reinforcing straps on their outer sides, and the reinforcing straps are offset from the front side plate and the rear side plate.

[0009] Preferably, the upper plate and the lower plate are provided with first hook-shaped parts on both the front and rear sides, and the front side plate and the rear side plate are provided with second hook-shaped parts on both the upper and lower sides, with the first hook-shaped parts cooperating with the second hook-shaped parts.

[0010] The beneficial effects of this utility model are:

[0011] Insulation material is filled within the frame formed by the upper plate, lower plate, front side plate, and rear side plate to create a structure that blocks heat conduction. An external insulation layer further enhances this double-layer insulation. Stainless steel reinforcement with a thermal conductivity only one-third that of carbon steel and shear-resistant steel are used, combined with carbon fiber wrapping and an epoxy coating to further reduce heat conduction. The shear-resistant steel enhances the structure's shear resistance, while its low thermal conductivity provides insulation. The upper and lower plates and side plates are quickly assembled via hook-like interlocking parts. The overall structure is simple, easy to manufacture, and cost-effective.

[0024] Example 1:

[0025] Figures 1-6This invention provides a thermal break connector for a main structure, comprising an upper plate 1 and a lower plate 2 arranged in parallel. The upper plate 1 and lower plate 2 are horizontally arranged, with a filling gap between them for insulating material 5. Front side plates 3 and rear side plates 4 are respectively arranged on the front and rear sides of the upper plate 1 and lower plate 2, and are vertically arranged. The upper and lower ends of the front side plates 3 and rear side plates 4 are connected to the upper plate 1 and lower plate 2 by snap-fit. In this embodiment, multiple front side plates 3 and rear side plates 4 are simultaneously connected to one upper plate 1 and one lower plate 2, forming a structural frame composed of the upper plate 1, lower plate 2, front side plates 3, and rear side plates 4. The hollow portion within this structural frame is filled with insulating material 5, forming the prototype of a thermal break structure.

[0026] The front side plate 3 and the rear side plate 4 are set at intervals, and the intervals allow the steel bars to pass through. The steel bars pass through the insulation material 5, and the two ends of the steel bars are connected to the cantilever structure 6 and the floor slab 7, so that the thermal break structure is embedded in the building structure. Specifically, the front end of the steel bar is connected to the cantilever structure 6, and the rear end of the steel bar is connected to the structural beam 8 and the floor slab 7. In actual construction, the steel bars need to be embedded in the cantilever structure 6, the insulation material 5, the structural beam 8, and the floor slab 7.

[0027] The reinforcing bars include upper tension bars 51 and lower compression bars 52. The upper tension bars 51 are placed on the upper layer of the insulation material 5, close to the upper plate 1, and are made of low thermal conductivity stainless steel (approximately 1 / 3 the strength of ordinary carbon steel). One end of the upper tension bars 51, which is anchored to the main structure, is wrapped with carbon fiber cloth 511, and then coated with a layer of epoxy resin to further block heat transfer from the bars and enhance the bond between the bars and the concrete. Furthermore, the spacing of the upper tension bars 51 is controlled within 100mm-150mm.

[0028] The lower reinforcing bar 52 is placed under the insulation material 5, close to the lower plate 2, and is made of low thermal conductivity stainless steel (about 1 / 3 of ordinary carbon steel). The diameter of the lower reinforcing bar 52 is generally twice that of the upper reinforcing bar 51, and the anchorage length at both ends is not less than 1 / 2 the thickness of the insulation material 5. The spacing of the lower reinforcing bar 52 is controlled within 100mm-150mm.

[0029] The insulation material 5 is also fitted with shear-resistant steel 53, which is I-shaped and made of low thermal conductivity stainless steel. It is positioned in the middle of the thermally broken bridge structure, with anchorage lengths at both ends not less than the thickness of the insulation material 5, sufficient to meet anchorage requirements. An epoxy resin adhesive layer 512 is coated on the surface of the shear-resistant steel 53 to strengthen the bond between the steel reinforcement and the concrete. Furthermore, a row of anchoring steel nails is welded to the upper and lower flanges of the shear-resistant steel 53 to increase the degree of anchorage with the concrete.

[0030] The upper plate 1, lower plate 2, front side plate 3, and rear side plate 4 are connected and fixed to each other by a snap-fit ​​method. Specifically, the upper plate 1 and lower plate 2 are provided with first hook-shaped parts 11 on the front and rear sides, and the front side plate 3 and rear side plate 4 are provided with second hook-shaped parts 31 on the upper and lower sides. The first hook-shaped parts 11 and the second hook-shaped parts 31 cooperate to enable the upper plate 1, lower plate 2, front side plate 3, and rear side plate 4 to be quickly assembled together to form the basic frame of the thermal break bridge.

[0031] This embodiment also enhances the stability of the thermal break structure by using a reinforcing strap 54. Specifically, the reinforcing strap 54 is wrapped around the outside of the upper plate 1 and the lower plate 2, and is offset from the front side plate 3 and the rear side plate 4. It is made of carbon fiber and is used to protect the thermal break structure, reinforce the structure, and improve stability.

[0032] After the main structure and thermal break structure are completed, an external insulation layer is installed on the surface where the thermal break structure contacts the outside world to further block heat transfer.

[0033] This invention first fills the frame formed by the upper plate 1, lower plate 2 and side plate with thermal insulation material 5 to directly block the heat conduction path of the cantilevered concrete structure, similar to the function of nylon thermal insulation strips in thermally broken aluminum profiles; secondly, it uses stainless steel steel bars and shear steel 53 with a thermal conductivity of only 1 / 3 that of ordinary carbon steel, and further reduces the heat transfer efficiency by wrapping with carbon fiber cloth 511 and epoxy resin adhesive layer 512; finally, after construction, an external thermal insulation layer is added to the contact surface to form a second thermal insulation barrier, similar to the thermal bridging design of the outer enclosure of a passive house.

[0034] In terms of structural mechanics optimization, the bonding strength with concrete is enhanced by using I-shaped shear steel 53 and anchoring steel nails, while low thermal conductivity materials are used to avoid local thermal bridging caused by metal thermal conduction; combined with the design of carbon fiber reinforcing straps 54 staggered wrapping the frame, the overall stability is improved, similar to the composite structure concept of thermally broken aluminum profiles.

[0035] In terms of ease of construction and durability, the upper plate 1 and lower plate 2 are quickly snapped together with the side plates through hook-shaped parts, realizing modular assembly and simplifying the on-site installation process. The process is similar to the roll-forming embedded technology of thermally broken aluminum profiles. At the same time, the anti-corrosion treatment of stainless steel materials and epoxy resin coating significantly improves durability and ensures long-term performance.

[0036] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
