Description

Technical Field

[0001] This utility model relates to the field of thermal bridge blocking technology for building nodes, specifically a thermal bridge blocking and adjustment structure for prefabricated building nodes. Background Technology

[0002] The structure disclosed in CN205134659U for blocking heat transfer through thermal bridges in curtain wall building nodes includes a curtain wall, an indoor metal keel, an outdoor metal keel and / or metal components, wherein an integral thermal insulation strip made of aerogel insulation blanket is fixed between the indoor metal keel and the curtain wall and / or the outdoor metal keel and / or metal components and is located near the outside.

[0003] In fact, the new structure is simple, easy to construct, has high structural strength, good fire resistance, low cost, and can significantly improve the energy-saving effect of the curtain wall.

[0004] While the comparative document demonstrates convenient construction techniques, it lacks a modular assembly design, making the installation of thermal insulation materials inconvenient. Furthermore, it cannot flexibly adjust the height of the thermal insulation materials, thus failing to meet the thermal insulation requirements of interior walls of varying heights. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prefabricated building node thermal bridge blocking and adjustment structure, which solves the problems of lack of modular assembly design, inconvenient installation of thermal insulation materials, and inability to flexibly adjust the height of thermal insulation materials, resulting in an inability to adapt to the thermal insulation needs of interior walls of different heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building node thermal bridge blocking and adjustment structure, comprising a T-shaped steel member, a thermal bridge block, and an extended thermal bridge block. One end of the T-shaped steel member is provided with a slide rail. The sides of both the thermal bridge block and the extended thermal bridge block are provided with sliders that match the slide rails. The thermal bridge block is slidably connected to the slide rail of the T-shaped steel member via its sliders. The extended thermal bridge block is slidably connected to the slide rail of the T-shaped steel member via its sliders. Both the thermal bridge block and the extended thermal bridge block have several fixing holes on their sides, and expansion screws are installed in the fixing holes.

[0007] In one specific embodiment, the thermal break bridge block and the extended thermal break block are arranged adjacent to each other on the slide rail, and the number of extended thermal break blocks can be increased by sliding.

[0008] In one specific embodiment, the fixing holes of the T-shaped steel are distributed on the side of the non-accessible slide rail.

[0009] In one specific embodiment, the slide rail is a groove structure along the back side of the T-shaped steel.

[0010] In one specific embodiment, the sliding range of the extended thermal break block on the slide rail allows its end to separate from or partially overlap with the thermal break bridge block.

[0011] In one specific embodiment, the thermal break bridge strip and the extended thermal break block are composite material components with low thermal conductivity.

[0012] Compared with the prior art, this utility model provides a prefabricated building node thermal bridge blocking and adjustment structure, which has the following beneficial effects:

[0013] In the technical solution disclosed in this utility model, modular rapid assembly is achieved through the sliding connection structure of the T-shaped steel slide rail, the thermal break bridge block, and the slider on the side of the extended thermal break block, which significantly improves the ease of installation. By utilizing the detachable design on the slide rail, the total height of the thermal break structure can be flexibly expanded and adjusted by adding different numbers of extended thermal break blocks, which can accurately adapt to the fitting requirements of different sized pre-installed component walls and insulation layers.

[0014] The thermal break bridge strips designed in this invention first temporarily position the T-shaped steel to the preset installation position of the main building structure; then, the sliders on the side of the thermal break bridge strips are aligned with the slide rails of the T-shaped steel and pushed into place to form a basic thermal break layer; one or more extended thermal break blocks are selected according to the wall height requirements, and their sliders are slid along the same slide rail to the adjacent position at the end of the thermal break bridge strips; after the total length of the thermal break bridge strips and extended thermal break blocks matches the target height, expansion bolts are used to sequentially pass through the fixing holes aligned on the sides of the T-shaped steel, the thermal break bridge strips, and all extended thermal break blocks to lock the overall structure onto the main building structure; the thermal break bridge strips and extended thermal break blocks made of low thermal conductivity composite materials completely cover the exposed metal surface of the T-shaped steel; finally, sealant is filled at the splicing joints to complete the airtight sealing.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a prefabricated building node thermal bridge blocking and adjustment structure includes a T-shaped steel bar 1, a thermal bridge block 3, and an extended thermal bridge block 4. One end of the T-shaped steel bar 1 is provided with a slide rail 2. The sides of the thermal bridge block 3 and the extended thermal bridge block 4 are provided with sliders 6 that match the slide rail 2. The thermal bridge block 3 is slidably connected to the slide rail 2 of the T-shaped steel bar 1 through its sliders 6, and the extended thermal bridge block 4 is slidably connected to the slide rail 2 of the T-shaped steel bar 1 through its sliders 6. The sides of the T-shaped steel bar 1, the thermal bridge block 3, and the extended thermal bridge block 4 are provided with several fixing holes, and expansion screws 5 are provided in the fixing holes.

[0023] The specific problem addressed in this embodiment is the lack of modular assembly design, which makes the installation of thermal insulation materials inconvenient. Furthermore, the inability to flexibly adjust the height of the thermal insulation material results in an inability to adapt to the thermal insulation requirements of interior walls of varying heights. This invention utilizes a sliding connection structure between the slide rail 2 of the T-shaped steel member 1 and the sliding blocks 6 on the sides of the thermal insulation bridge block 3 and the extended thermal insulation block 4, achieving modular and rapid assembly and significantly improving installation convenience. The detachable design on the slide rail 2 allows for flexible expansion and adjustment of the total height of the thermal insulation structure by adding different numbers of extended thermal insulation blocks 4, precisely adapting to the bonding requirements of pre-installed wall components of different sizes with the insulation layer.

[0024] The thermal break bridging block 3 and the extended thermal break block 4 are provided. A slide rail 2 is provided at one end of the T-shaped steel member 1. Sliding blocks 6 matching the slide rail 2 are provided on the sides of both the thermal break bridging block 3 and the extended thermal break block 4. The thermal break bridging block 3 is slidably connected to the slide rail 2 of the T-shaped steel member 1 via its sliding blocks 6, and the extended thermal break block 4 is slidably connected to the slide rail 2 of the T-shaped steel member 1 via its sliding blocks 6. In this specific embodiment, the T-shaped steel member 1 is first temporarily positioned at a preset installation position in the main building structure; then, the sliding blocks 6 on the side of the thermal break bridging block 3 are aligned with the slide rail 2 of the T-shaped steel member 1 and pushed into place, forming the basic thermal break layer. According to the wall height requirements, select one or more extended thermal break blocks 4, and slide their sliders 6 along the same slide rail 2 to the adjacent position at the end of the thermal break bridge block 3; after the total length of the thermal break bridge block 3 and the extended thermal break block 4 matches the target height, use expansion screws 5 to pass through the fixing holes aligned on the sides of the T-shaped steel 1, the thermal break bridge block 3 and all the extended thermal break blocks 4 in sequence to lock the overall structure to the main building structure; the thermal break bridge block 3 and the extended thermal break block 4 made of low thermal conductivity composite material completely cover the exposed metal surface of the T-shaped steel 1; finally, fill the joint with sealant to complete the airtight seal.

[0025] In this specific embodiment, the fixing holes of the T-shaped steel 1 are distributed on the side of the T-shaped steel 1 where the slide rail 2 is not located. The fixing holes of the T-shaped steel 1 are all set on the vertical side of the T-shaped steel 1 where the slide rail 2 is not located. When anchoring, the operator directly drives the expansion bolt 5 through the fixing hole on this side into the main structure of the building. This design ensures that the installation plane of the expansion bolt 5 does not interfere with the plane where the slide rail 2 is located. When adjusting or assembling the thermal break bridge block 3 and the extended thermal break block 4, the spatial separation between the fixing holes and the slide rail 2 avoids the bolt operation from obstructing the movement of the slider 6 inside the slide rail 2, ensuring the thermal break block assembly can slide and adjust on the slide rail 2 without resistance. This structure maintains the rigid connection strength between the T-shaped steel 1 and the main structure, and realizes the parallel and mutually exclusive adjustment and locking operations through functional zoning. It solves the installation jamming problem caused by the spatial conflict between anchors and functional components in traditional nodes, and improves construction efficiency and adjustment accuracy.

[0026] Working principle: The T-shaped steel 1 is fixed to the main building structure by expansion bolts 5 or pre-fixed to the building structure through the fixing holes on its side, forming a support base; the slide rail 2 of the T-shaped steel 1 serves as a guide reference, allowing the thermal break bridge block 3 to slide into the slide rail 2 through the slider 6 on its side to form a basic thermal break unit; according to the actual insulation layer height requirements, at least one extended thermal break block 4 is selected, and its slider 6 is slidably assembled along the same slide rail 2 to the adjacent position of the thermal break bridge block 3 or the end of the previous extended thermal break block 4. The total height of the thermal break structure is expanded by increasing or decreasing the number of extended thermal break blocks 4; after all components are positioned, the expansion bolts 5 are used to form a support base. Expansion bolts 5 are inserted synchronously through the fixing holes aligned on the sides of T-shaped steel 1, thermal break strips 3, and all extended thermal break blocks 4, rigidly anchoring the entire structure to the building body. After assembly, the low thermal conductivity thermal break strips 3 and extended thermal break blocks 4 completely cover the exposed metal surface of T-shaped steel 1, physically isolating the metal heat conduction path to block thermal bridges. The design of fixing holes of T-shaped steel 1 on the side of non-slide rail 2 ensures that the internal components of slide rail 2 move without interference, ensuring smooth height adjustment. Finally, sealant is filled into the splice joint to achieve airtight sealing, forming a complete working system from structural anchoring, height adjustment to thermal bridge blocking.
