Description

Technical Field

[0001] This utility model relates to the field of near-zero energy building technology, and in particular to a thermal break bridge bracket for near-zero energy office buildings. Background Technology

[0002] Near-zero energy buildings are buildings that adapt to climate characteristics and natural conditions, employing building envelopes with superior thermal insulation and airtightness, utilizing efficient fresh air heat recovery technology to minimize heating and cooling needs, and fully leveraging renewable energy to provide a healthy and comfortable indoor environment with less energy consumption while meeting the basic requirements of green buildings. Thermal bridges have a more significant impact on near-zero energy buildings. Traditional metal brackets can cause localized thermal bridges on the walls, leading to concentrated heat loss. Strict control over thermal bridges is essential in the design of near-zero energy buildings, requiring a thermal bridge-free design for the building envelope.

[0003] For thermal bridges at the installation structure of insulation board brackets, it is crucial to address the increased energy consumption or resource waste caused by untreated or over-treated thermal bridges, thereby reducing building heating and cooling energy consumption and achieving a more uniform and comfortable indoor temperature. However, most current brackets for this structure are one-piece molded components made of carbon steel. Due to their high thermal conductivity, the contact area between the bracket and the wall is large, forming significant thermal bridges and leading to increased energy consumption. Therefore, there is an urgent need to design a thermal bridge-breaking bracket for near-zero energy office buildings that meets both load-bearing requirements and thermal bridge-breaking functions, achieving a balance between the two. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: to provide a thermal break bridge bracket for near-zero energy consumption office buildings, in view of the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: a thermal break bracket for near-zero energy consumption office buildings, comprising:

[0006] The base has a mounting beam assembly at the bottom;

[0007] The support assembly is slidably mounted on the wall of the base to support the insulation board;

[0008] The first mounting component, located on the base and mounting beam assembly, is used to fix the base and mounting beam assembly to the concrete wall surface.

[0009] The second mounting component, located on the wall of the base, is used to fix the platform assembly.

[0010] The heat insulation layer, located outside the first mounting assembly, is designed to prevent heat from the base and mounting beam assembly from entering the concrete wall.

[0011] Using the above-mentioned technical means, the base and support components are assembled into a thermal break bracket structure by the first mounting component and the second mounting component. Compared with the one-piece molded structure, the split design can break the continuous metal path of heat conduction. In addition, a heat insulation layer is added to the outside of the first mounting component to block some of the heat, thereby reducing the overall heat conduction efficiency.

[0012] In some embodiments, the support platform assembly includes a support platform, a support base, a mounting platform, a reinforcing member, a movable platform, and a guide member. The side wall of the mounting platform is slidably mounted on the wall of the base via the movable platform. The top of the mounting platform is connected to the support platform via the support base. The bottom of the mounting platform is connected to a reinforcing member that can slide relative to the wall of the base. The reinforcing member can provide support for the bottom of the mounting platform during its sliding. The end of the mounting platform is connected to a guide member that can be inserted and engaged with the base. The guide member can provide guidance for the mounting platform during its sliding.

[0013] In some embodiments, a limiting groove is provided on the wall surface of the base plate along the sliding direction of the mounting platform. The reinforcing member includes a reinforcing plate and a reinforcing rib. The bottom of the mounting platform is connected to the reinforcing plate via the reinforcing rib. The reinforcing rib is arranged obliquely, the reinforcing plate is arranged vertically, and the reinforcing plate is slidably engaged inside the limiting groove.

[0014] In some embodiments, the wall surface of the base plate is provided with an I-shaped groove, and the movable platform is slidably embedded in the I-shaped groove, and the movable platform can slide along the axial direction of the I-shaped groove.

[0015] In some embodiments, the guide includes a guide rod, the base has a guide hole facing the I-shaped groove, the end of the movable stage is connected to the guide rod, the guide rod is inserted into the guide hole, so that after the movable stage slides into the I-shaped groove, the guide rod is inserted into the guide hole.

[0016] In some embodiments, the second mounting component includes a first connecting bolt, a set of first connecting holes are provided in the I-beam groove, and a threaded hole corresponding to the first connecting hole is provided through the moving platform. The first connecting bolt can be installed in the first connecting hole through the threaded hole to fix the moving platform to the base.

[0017] In some embodiments, the second mounting assembly further includes a fixing platform and a second connecting bolt. The fixing platform is connected to the wall of the base. The fixing platform has snap-fit ​​grooves on both sides. The mounting platform has a snap-fit ​​protrusion at the end facing the fixing platform. The snap-fit ​​protrusion and the snap-fit ​​groove can be inserted and engaged. A set of second connecting holes are provided through the snap-fit ​​protrusion. A third connecting hole corresponding to the second connecting holes is provided through the snap-fit ​​groove. When the second connecting hole and the third connecting hole are on the same axis, the second connecting bolt can pass through the second connecting hole and the third connecting hole to thread the mounting platform and the fixing platform.

[0018] In some embodiments, the first mounting assembly includes a first tie bolt, a second tie bolt, and a nut. The nut is embedded in the concrete wall. The mounting beam assembly has a plurality of first tie bolts arranged axially, and the base has a plurality of second tie bolts arranged axially. The first tie bolts and the second tie bolts are threadedly connected to the embedded nuts one by one.

[0019] In some embodiments, the base is made of polypropylene, the heat insulation layer includes a plastic alloy layer, the first tie bolt and the second tie bolt are covered with a plastic alloy layer, and the nut is heat-insulated.

[0020] In some embodiments, the mounting beam assembly includes an I-beam mounting beam, with insulation material filling the space between the I-beam mounting beam and the wall. The I-beam mounting beam has a fireproof board external bracket near the indoor side, and a fireproof sheet is installed on the fireproof board external bracket.

[0021] The beneficial effects of this utility model are:

[0022] 1. By using a base made of a low thermal conductivity material, the heat directly conducted through this component is reduced. The base and mounting beam assembly are fixed to the concrete wall using a first mounting component, providing support for the overall structure and ensuring sufficient load-bearing capacity. An insulation layer on the outside of the first mounting component blocks heat transfer into the wall. Simultaneously, the support assembly can slide on the base, allowing for flexible position adjustment and reducing direct contact area, thus minimizing heat conduction paths. Since traditional one-piece molded structures tend to create continuous metal paths from the outside in or from the inside out, making heat conduction easier, this application employs a split assembly design to break this continuity, interrupting the heat conduction path from the bracket to the wall as much as possible. This forces heat transfer to pass through multiple breakpoints and material transitions, thereby reducing overall heat conduction efficiency. Attached Figure Description

[0032] 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.

[0033] Example 1:

[0034] Combination Figures 1 to 4 As shown, this embodiment is a thermal break bracket for near-zero energy office buildings, including a base 1, a support assembly 3, a first mounting assembly, a second mounting assembly, and an insulation layer. A mounting beam assembly is connected to the bottom of the base 1. Both the base 1 and the mounting beam assembly are equipped with the first mounting assembly, which is used to fix the base 1 and the mounting beam assembly to the concrete wall surface. An insulation layer is provided on the outside of the first mounting assembly, which can prevent heat from the base 1 and the mounting beam assembly from entering the concrete wall. The support assembly 3 is slidably mounted on the wall surface of the base 1, and the support assembly 3 is used to support the insulation board. The second mounting assembly is provided on the wall surface of the base 1, and the second mounting assembly is used to fix the support assembly 3 to the base 1.

[0035] Furthermore, the base 1 is made of a low thermal conductivity material. In this embodiment, the base 1 is made of polypropylene, which helps to reduce heat conduction to the wall through the base 1 and effectively reduce the thermal bridging effect.

[0036] In some implementation schemes, such as Figure 1 and Figure 2 As shown, the mounting beam assembly includes an I-beam mounting beam 204, and the bottom of the base 1 is fixedly connected to the I-beam mounting beam 204. The first mounting assembly includes a first tie bolt 206, a second tie bolt 208, and nuts. The nuts are embedded in the concrete wall. Multiple first tie bolts 206 are arranged axially at intervals on the I-beam mounting beam 204, and multiple second tie bolts 208 are arranged axially at intervals on the wall surface of the base 1. Both the first tie bolts 206 and the second tie bolts 208 can be threadedly connected to the embedded nuts one by one.

[0037] Furthermore, the space between the I-beam 204 and the wall is filled with insulation material, and the I-beam 204 is provided with a fireproof board external bracket near the interior side, on which a fireproof sheet 205 is installed.

[0038] By filling with insulation material, a heat insulation layer is formed between the I-beam 204 and the wall, reducing the heat conduction to the exterior wall through the I-beam 204, thereby interrupting the heat conduction path generated by the I-beam 204 and avoiding energy loss caused by thermal bridging.

[0039] Furthermore, the insulation layer includes a plastic alloy layer. The first tie bolt 206 and the second tie bolt 208 are covered with a plastic alloy layer to block heat conduction to the concrete wall through the first tie bolt 206 and the second tie bolt 208, reducing the risk of thermal bridging. In this embodiment, the pre-embedded nuts are heat-insulated, so that the nuts are heat-insulated from the concrete wall. Thus, the first tie bolt 206, the second tie bolt 208, and the nuts do not come into contact with the pre-embedded substrate for heat transfer, thereby realizing the thermal bridging function of the base 1.

[0040] Furthermore, in this embodiment, the diameter of the first tie bolt 206 and the second tie bolt 208 is 12mm, and the horizontal spacing is 800mm. The first tie bolt 206 and the second tie bolt 208 bear the horizontal load of the base 1, including wind load and seismic load.

[0041] In some implementation schemes, such as Figure 1 , Figure 2 and Figure 4As shown, the support platform assembly 3 includes a support platform 305, a support platform 304, a mounting platform 303, a reinforcing member, a movable platform 301, and a guide member. The side wall of the mounting platform 303 is slidably mounted on the wall of the base 1 via the movable platform 301. The top of the mounting platform 303 is connected to the support platform 305 via the support platform 304. The bottom of the mounting platform 303 is connected to a reinforcing member that can slide relative to the wall of the base 1. The reinforcing member can provide support for the bottom of the mounting platform 303 during its sliding process. The end of the mounting platform 303 is connected to a guide member that can be inserted and engaged with the base 1. The guide member can provide guidance for the mounting platform 303 during its sliding process.

[0042] Furthermore, a pair of I-shaped grooves 201 are symmetrically provided on the wall surface of the base plate. The connecting protrusions on both sides of the movable platform 301 can be inserted and engaged with the connecting grooves in the I-shaped grooves 201, so that the pair of movable platforms 301 are slidably embedded in the corresponding I-shaped grooves 201, and the movable platform 301 can slide along the axial direction of the I-shaped grooves 201.

[0043] The insertion and connection between the movable platform 301 and the I-beam groove 201 facilitates quick installation and disassembly, while ensuring that the mounting platform 303 slides smoothly along the axial direction. Furthermore, the split connection of the support platform improves the heat insulation efficiency.

[0044] Furthermore, the reinforcing member includes a reinforcing plate 306 and a reinforcing rib 307. The bottom of the wall of the base 1 is provided with a limiting groove 207 along the sliding direction of the mounting platform 303. The bottom of the mounting platform 303 is connected to a reinforcing rib 307 arranged obliquely. The end of the reinforcing rib 307 away from the mounting platform 303 is connected to a reinforcing plate 306 arranged vertically. The reinforcing plate 306 can be snapped into the limiting groove 207 and slide in fit.

[0045] The reinforcing plate 306 and the reinforcing rib 307 form a triangular structure to provide additional support, which enhances the support force at the bottom of the mounting platform 303 and the bearing force of the support platform 305, increases the strength and stability of the structure, and reduces the direct contact area to reduce heat conduction.

[0046] Furthermore, the guide includes a guide rod 3011. In this embodiment, the base 1 is provided with two sets of guide holes 203 facing the corresponding side slots 201. The end of the moving platform 301 is connected to the guide rod 3011. The guide rod 3011 and the corresponding guide hole 203 are on the same axis and can be inserted and matched, so that after the moving platform 301 slides into the slot 201, the guide rod 3011 is inserted into the guide hole 203.

[0047] The guide rod 3011 is inserted into the guide hole 203 to ensure that the mounting platform 303 remains stable during movement and avoids deviation.

[0048] In some implementation schemes, such as Figure 1 As shown, the second mounting assembly includes a first connecting bolt 302, a set of first connecting holes 202 are provided in the I-beam groove 201, and a threaded hole corresponding to the first connecting hole 202 is provided through the moving platform 301. The threaded hole and the first connecting hole 202 are threadedly engaged with the first connecting bolt 302. The first connecting bolt 302 can be installed in the first connecting hole 202 through the threaded hole to fix the moving platform 301 to the base 1.

[0049] In some implementation schemes, such as Figure 3 As shown, the second mounting assembly also includes a fixing platform 309 and a second connecting bolt 311. The fixing platform 309 is fixedly connected to the wall of the base 1. The fixing platform 309 has snap-fit ​​grooves on both sides. The mounting platform 303 has a snap-fit ​​protrusion at its end facing the fixing platform 309. The snap-fit ​​protrusion and the snap-fit ​​groove can be inserted into each other. A set of second connecting holes 308 are provided through the snap-fit ​​protrusion. A third connecting hole 310 corresponding to the second connecting hole 308 is provided through the snap-fit ​​groove. Both the second connecting hole 308 and the third connecting hole 310 are threadedly connected to the second connecting bolt 311. When the snap-fit ​​protrusion and the snap-fit ​​groove are inserted into each other, and the second connecting hole 308 and the third connecting hole 310 are on the same axis, the second connecting bolt 311 can pass through the second connecting hole 308 and the third connecting hole 310 to thread-fix the mounting platform 303 and the fixing platform 309.

[0050] Furthermore, in this embodiment, the top of the third connecting hole 310 is countersunk.

[0051] The countersunk hole structure allows the bolt head to be fully embedded in the hole, resulting in a smooth and flat surface after installation, which is aesthetically pleasing. At the same time, when the bolt head is fully embedded in the countersunk hole, it fits more tightly against the bottom of the hole, increasing the stability of the fixing point, reducing the risk of bolt loosening due to external forces, and improving the safety and stability of the overall structure.

[0052] Furthermore, in this embodiment, the reinforcing plate 306, the reinforcing rib 307, and the support 305 are all made of stainless steel, with a thermal bridge value of 0.37 W / K. The components used in this embodiment are all regular structures, resulting in low production costs and minimal transportation losses.

[0053] The implementation principle of a thermal break bracket for near-zero energy office buildings is as follows:

[0054] Regarding material selection, since the base 1 has a large contact area with the concrete wall, this design uses materials with low thermal conductivity to manufacture the base 1 and other components, reducing heat conduction through these components. For insulation, key connection points, including the first tie bolt 206, the second tie bolt 208, and the nuts, are insulated to prevent heat conduction along the bolts to the wall. By rationally arranging the positional relationship of each component, continuous high thermal conductivity paths are avoided, ensuring that heat cannot directly penetrate the entire bracket structure. The use of low thermal conductivity materials and effective insulation measures reduces heat conduction through the bracket structure to the wall. Simultaneously, the overall structure still meets the necessary load-bearing requirements, ensuring the safety and stability of the building.

[0055] Example 2:

[0056] This embodiment describes an assembly method for a thermal break bracket used in near-zero energy office buildings, comprising the following steps:

[0057] In use, firstly, install a fireproof board external bracket on the indoor side of the I-beam mounting beam 204, and then install a fireproof thin plate 205 on it. Insulation material is then filled between the I-beam mounting beam 204 and the wall as needed. Next, connect the I-beam mounting beam 204 and the base 1 to the corresponding pre-embedded nuts using the first tie bolt 206 and the second tie bolt 208, respectively. Place the moving platform 301 in the I-beam groove 201, while simultaneously placing the reinforcing plate 306 in the limiting groove 207. Slide the moving platform 301 axially towards the guide hole 203 along the I-beam groove 201 until the guide rod 3011 on the moving platform 301 is inserted into the guide hole 203 on the same axis. Pass the first connecting bolt 302 through the threaded hole on the moving platform 301 into the first connecting hole 202, thus completing the fixed connection between the moving platform 301 and the base 1. After installation, the snap-fit ​​protrusion on the mounting platform 303 is inserted into the snap-fit ​​groove on the corresponding side of the fixing platform 309. At this time, the second connecting hole 308 on the mounting platform 303 and the third connecting hole 310 on the fixing platform 309 are on the same axis. The mounting platform 303 and the fixing platform 309 are fixed by the second connecting bolt 311 passing through the second connecting hole 308 and the third connecting hole 310.

[0058] 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.
