Description

Technical Field

[0001] This invention relates to the field of thermal insulation structure technology, and in particular to a thermal insulation structure for green building systems. Background Technology

[0002] With the development of the times, "carbon peaking and carbon neutrality" has become the goal of many fields. As a major consumer of energy and a major emitter of carbon (accounting for about 40% of global carbon emissions), the building sector has made energy conservation and carbon reduction a key battleground for achieving the "dual carbon" goal. Traditional building insulation mainly relies on "single materials + passive protection" (such as polystyrene boards pasted on the exterior walls). However, this method has defects such as "rapid decay of insulation performance, serious thermal bridging effect, and low construction efficiency". Therefore, with the increasing requirements for building energy conservation, insulation technology is gradually shifting towards "system integration".

[0003] In the patent document with publication number "CN217299353U", an environmentally friendly thermal insulation wall for prefabricated green buildings is proposed. It mainly uses a high-quality and efficient thermal insulation material that integrates a closed microporous structure and a glass fiber alkali-resistant mesh structure on the inner wall insulation coating layer of the thermal insulation and flame retardant device to ensure the thermal insulation performance of the prefabricated wall. However, its overall volume is large and requires "overall layer-by-layer construction". For the early construction and later maintenance, the overall construction efficiency is low, the transportation cost is high, and the maintenance is also more difficult.

[0004] Meanwhile, there are two types of insulation layers. One type is a detachable, multi-layer insulation layer, which is convenient to transport due to its inherent characteristics. However, during installation, it is usually connected to the steel structure column by adhesive. If the insulation layer is fixed by adhesive alone, it may experience "hollowing out and falling off" due to "temperature changes" (thermal expansion and contraction), which will affect its insulation performance and does not meet the current environmental protection concept. The other type of insulation layer has a larger overall thickness in order to improve the insulation effect, but it is more troublesome to transport and requires the use of large equipment, thus increasing the transportation cost. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art that after the steel support structure is installed, a large amount of mud still needs to be poured into most areas, making the disassembly and assembly of the prefabricated steel support structure in deep foundation pits still difficult and inconsistent with the existing environmental protection concept. The invention proposes a thermal insulation structure for green building systems.

[0006] The technical solution of this invention: A thermal insulation structure for green building systems, comprising a multi-layered thermal insulation component, wherein the thermal insulation component includes an insulation layer, and further includes:

[0007] A bidirectional positioning component for protecting the internal temperature of the insulation component, the bidirectional positioning component includes an annular insulation airbag installed in the insulation layer, a plurality of telescopic slide rods are fixedly installed on the side wall of the insulation airbag, and a locking ring is slidably installed on the outer side of the plurality of telescopic slide rods.

[0008] An end connection assembly for connecting two adjacent insulation layers includes an auxiliary rotating ring rotatably mounted at the bottom of the insulation layer. A circular guide ring is fixedly mounted on the inner wall of the auxiliary rotating ring. A fixing ring is fixedly mounted at the bottom of the insulation layer. A vertical sliding groove is opened inside the fixing ring. An adhesive storage tube is slidably mounted inside the fixing ring and the auxiliary rotating ring. A piston rod is slidably mounted inside the adhesive storage tube. An L-shaped spray tube is fixedly mounted on one side of the adhesive storage tube extending to the outer wall of the insulation airbag.

[0009] Optionally, the number of insulation layers is multiple sets, and multiple insulation cover plates are fixedly installed on the top of the multiple sets of insulation layers, with multiple positioning plates fixedly installed between every two insulation cover plates.

[0010] Optionally, the multiple positioning plates are glued together, and the multiple positioning plates are installed in a staggered manner.

[0011] Optionally, the top of the insulation layer has an insulation cavity adapted to the insulation airbag, and multiple springs are fixedly installed between the end of the telescopic slide rod extending to the inner wall of the insulation airbag and the locking ring.

[0012] Optionally, the insulation component further includes an annular slide for positioning and assisting the rotation of the rotating ring, and a vertical slide for the sliding of the L-shaped injection pipe is provided at the bottom of the insulation layer, the vertical slide and the annular slide being connected.

[0013] Optionally, the end connection assembly further includes a positioning cylinder extending from the bottom surface of the insulation assembly and adapted to the locking ring. The inner wall of the positioning cylinder is provided with a locking groove adapted to the telescopic slide rod. The elasticity of the insulation airbag drives the four telescopic slide rods to clamp the positioning cylinder, thereby reducing the shaking caused by the multi-layer insulation structure.

[0014] Optionally, the bottom of the positioning cylinder and the end of the telescopic slide rod extending to the inner wall of the engagement ring are both arc-shaped surfaces.

[0015] Optionally, a handle block is fixedly installed on the outer side of the auxiliary rotating ring, the fixing ring is fixedly installed on the outer side of the positioning cylinder, and the positioning cylinder is fixedly installed on the bottom of the insulation layer.

[0016] Optionally, the bottom of the insulation layer is provided with multiple limiting holes, which are aligned with the side wall mounting holes of the fixing ring, and a double-layer threaded rod is rotatably installed inside the fixing ring and the limiting holes.

[0017] Optionally, both the handle block and the outer side of the double-layer threaded rod are fitted with bidirectional locking blocks, and the double-layer threaded rod is rotatably mounted with nuts on both the upper and lower surfaces of the bidirectional locking blocks.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When the heat-insulating airbag expands due to heat, it applies a clamping force to the positioning cylinder, while the L-shaped spray pipe restricts the outward movement of the heat-insulating airbag. When the heat-insulating airbag contracts due to cold, the side wall of the locking groove and the adhesive work together to reduce the impact of thermal expansion and contraction on the connection position of the insulation layer.

[0020] 2. The insulation airbag is squeezed outward along the locking ring by the telescopic sliding rod. The insulation airbag expands under pressure, thereby clamping and positioning the insulation layer. This allows the insulation layer and the steel structure or other bidirectional positioning components to be transported in a stacked manner, saving transportation space. During transportation, adjacent insulation layers and steel structures are clamped by the expansion of the insulation airbag through the bidirectional positioning components, resulting in higher stability of the material during transportation.

[0021] 3. The use of small, segmented insulation panels facilitates transportation and installation, and the staggered layout of the positioning plates enhances sealing and reduces thermal bridging. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1-3 , Figure 5 and Figure 8 As shown, the present invention proposes a thermal insulation structure for a green building system, comprising a thermal insulation component 1 with multiple layers of materials stacked for thermal insulation. The thermal insulation component 1 includes an insulation layer 102 and a bidirectional positioning component 2 for protecting the internal temperature of the thermal insulation component 1. The bidirectional positioning component 2 includes an annular thermal insulation airbag 201 installed within the insulation layer 102. Multiple telescopic sliding rods 203 are fixedly installed on the sidewalls of the thermal insulation airbag 201, and locking rings 202 are slidably installed on the outer sides of the multiple telescopic sliding rods 203. The number of insulation layers 102 is multiple. Multiple insulation cover plates 101 are fixedly installed on the top of multiple sets of insulation layers 102. Multiple positioning plates 103 are fixedly installed between every two insulation cover plates 101. The positioning plates 103 are glued together and are staggered. An insulation cavity 104 adapted to the insulation airbag 201 is opened on the top of the insulation layer 102. Multiple springs 204 are fixedly installed between the end of the telescopic sliding rod 203 extending to the inner wall of the insulation airbag 201 and the locking ring 202. According to building installation requirements, the insulation cover... The panel 101 can be a covering surface, covering the underside of the multi-layer thermal insulation material. In the prior art, covering surfaces are transported in small pieces for ease of transport. In detail, the thermal insulation covering panel 101 here is the bottom layer of thermal insulation that needs to be installed on the building wall. It is equivalent to covering the outer surface of the multi-layer thermal insulation material with a protective film, which wraps the multi-layer thermal insulation material into a whole to reduce heat loss. The end connecting component 3 of the bottom layer of thermal insulation 102 faces outward to facilitate the connection of the bidirectional positioning component of the next layer of thermal insulation 102. After covering the surface of the multi-layer thermal insulation material, in order to better adapt to the volume of the multi-layer thermal insulation material stacked together and to make its sealing performance better, positioning plates 103 are installed staggered between every two thermal insulation covering panels 101. Since building materials are easily affected by thermal expansion and contraction, when the positioning plates 103 expand or contract, they will be subjected to the stress generated by the staggered positioning plates 103 around them, thus extending their service life. Moreover, the staggered layout of the positioning plates 103 enhances the sealing performance and reduces the thermal bridging effect.

[0038] The end connection component 3 includes a positioning cylinder 302 extending from the bottom surface of the heat insulation component 1 and adapted to the locking ring 202. The inner wall of the positioning cylinder 302 is provided with a locking groove 312 adapted to the telescopic slide rod 203. The elastic force of the heat insulation airbag 201 drives the four telescopic slide rods 203 to clamp the positioning cylinder 302. The bottom of the positioning cylinder 302 and the end of the telescopic slide rod 203 extending to the inner wall of the locking ring 202 are both arc-shaped surfaces.

[0039] For the transportation of multi-layer thermal insulation materials and their adaptation for transportation with the building's steel structure, positioning cylinders 302, mounted on the bottom of both the steel structure and the insulation layer 102, can be inserted into the insulation cavity 104. The positioning cylinders 302 can be inserted into the insulation airbag 201. Since the diameter formed by the telescopic slide rod 203 between the locking rings 202 is smaller than the diameter of the positioning cylinder 302, when the positioning cylinder 302 slides into the locking rings 202, the arc-shaped surface of the positioning cylinder 302 and the telescopic slide rod 203... The curved surfaces create a mutual squeezing effect, causing the telescopic slide bar 203 to squeeze the heat insulation airbag 201 outward along the locking ring 202. The heat insulation airbag 201 expands under pressure, thereby clamping and positioning the heat insulation layer 102. This allows the heat insulation layer 102 and the steel structure or other bidirectional positioning components 2 to be transported in a stacked manner, saving transportation space. Furthermore, since the heat insulation layer 102 and the steel structure or other bidirectional positioning components 2 are both clamped by the expansion of the heat insulation airbag 201, the material has higher stability during transportation.

[0040] This design ensures the stability of the multi-layer structure during transportation and reduces shaking. Meanwhile, the inner wall of the positioning cylinder 302 has a locking groove 312. When the telescopic slide rod 203 slides into the locking groove 312 under the elastic force of the spring 204, it forms a positioning state, further enhancing the connection strength.

[0041] like Figures 2-9As shown, an end connection assembly 3 is used to connect two adjacent insulation components 1. The end connection assembly 3 includes an auxiliary rotating ring 308 rotatably mounted on the bottom of the insulation layer 102. A circular guide ring 309 is fixedly mounted on the inner wall of the auxiliary rotating ring 308. A fixing ring 301 is fixedly mounted on the bottom of the insulation layer 102. A vertical sliding groove 306 is opened inside the fixing ring 301. An adhesive storage tube 311 is slidably mounted inside the fixing ring 301 and the auxiliary rotating ring 308. A piston rod 307 is slidably mounted inside the adhesive storage tube 311. An L-shaped spray pipe 310 is fixedly mounted on one side of the adhesive storage tube 311 extending to the outer wall of the insulation airbag 201. The insulation component 1 includes an annular slide 105 for positioning the rotation of the auxiliary rotating ring 308. The bottom of the insulation layer 102 has a vertical slide 106 for the L-shaped injection pipe 310 to slide. The vertical slide 106 is connected to the annular slide 105. A handle block 303 is fixedly installed on the outer side of the auxiliary rotating ring 308. A fixing ring 301 is fixedly installed on the outer side of the positioning cylinder 302. The positioning cylinder 302 is fixedly installed on the bottom of the insulation layer 102. The bottom of the insulation layer 102 has multiple limiting holes 107. The limiting holes 107 are aligned with the side wall mounting holes of the fixing ring 301. A double-layer threaded rod 305 is rotatably installed inside the fixing ring 301 and the limiting holes 107. A bidirectional locking block 304 is sleeved on the outer side of both the handle block 303 and the double-layer threaded rod 305. The double-layer threaded rod 305 is located at the bidirectional locking block 304. Nuts are installed on both the top and bottom surfaces. As the positioning cylinder 302 continues to move downward toward the engaging ring 202, the telescopic slide rod 203 slides into the engaging groove 312 of the positioning cylinder 302. Due to the elasticity of the spring 204, the telescopic slide rod 203 can be inserted into the engaging groove 312, thus positioning the positioning cylinder 302. At the same time, the fixing ring 301 on the periphery of the positioning cylinder 302 below is fixed. Construction workers can manually rotate the circular guide ring 309, which drives the annular slide 105 to rotate. The circular guide ring 309, through the transmission of the internal arc-shaped guide rail, causes the glue storage tube 311 to move along the inner wall of the arc-shaped guide rail and the vertical track of the fixing ring 301, thus causing the glue storage tube 311 to move. 11. The L-shaped injection pipe 310 moves along the annular slide 105 towards the heat-insulating airbag 201 until the L-shaped injection pipe 310 fully clamps the heat-insulating airbag 201. At this time, the double-layer threaded rod 305 is manually rotated. The double-layer threaded rod 305 is fixed inside the heat-insulating layer 102 along the threads of the fixing ring 301 and the threads inside the limiting hole 107. According to the volume change of the positioning cylinder 302, that is, different steel materials are selected for the installation of bidirectional locking blocks 304 of different lengths. The handle block 303 is located in the middle position of the two sets of bidirectional locking blocks 304. At this time, the bidirectional locking blocks 304 are sleeved, and the nut is rotated to fix the bidirectional locking blocks 304 and the handle block 303 in this position. The outer wall of the heat-insulating airbag 201 is pushed and clamped by the L-shaped injection pipe 310.The inner wall of the insulation airbag 201 is clamped and sealed by the positioning cylinder 302, resulting in a relative positioning state between the three. Simultaneously, construction workers can push the piston rod 307, and the glue storage tube 311 sprays the stored glue through the L-shaped spray pipe 310 to the connection between the insulation airbag 201 and the insulation cavity 104. It should be noted that compared to directly bonding the insulation airbag to the inner wall of the insulation layer 102 during production, the detachable design of the insulation airbag 201 facilitates later transportation and replacement of any defective insulation airbags found on-site. Furthermore, the connection between the positioning cylinder 302 and the insulation airbag 201, and the large amount of glue sprayed onto the surface of the insulation airbag 201 by the L-shaped spray pipe 310, exert pressure on the connection between the insulation airbag 201 and the positioning cylinder 302, thus ensuring proper insulation. The airbag 201 is installed more stably. It should be noted that the piston rod 307 and the glue storage tube 311 are detachable. During transport and transportation, the inside of the glue storage tube 311 is filled with glue. During on-site installation, glue can be filled inside the glue storage tube 311. When the insulating airbag 201 expands due to heat, it is fully clamped by the positioning cylinder 302, while the outside of the insulating airbag 201 is positioned by the L-shaped spray pipe 310 and cannot move. When the insulating airbag 201 contracts due to cold, it is positioned by the limiting effect of the side wall of the locking groove 312 and the adhesiveness of the side wall glue. Compared with the existing technology that uses bolt installation or relies entirely on glue installation, this method extends the service life of the equipment, reduces the impact of thermal expansion and contraction, and improves the sealing of the connections between various components.

[0042] To explain, the gap between the inner wall of the heat-insulating airbag 201 and the locking ring 202 is filled with heat-insulating material that matches the gap, positioning the inner wall of the heat-insulating airbag 201 and the locking ring 202 in the middle position, and simultaneously positioning the heat-insulating airbag 201, so that the heat-insulating cavity 104 is in a relatively full state. At this time, the heat-insulating airbag 201 acts as a positioning component connecting the front and rear heat-insulating layers 102. When the heat-insulating airbag 201 is heated or cooled, it will transmit the pressure to the inner wall of the heat-insulating cavity 104 or to the outer wall of the locking ring 202 through itself and the heat-insulating material, thereby reducing the influence on the internal temperature of the heat-insulating cavity 104, so that the inside of the heat-insulating cavity 104 is always in a relatively sealed state.

[0043] Furthermore, the outer wall shape of the locking ring 202 can be designed to match the inner wall of the heat-insulating airbag 201, replacing the filling of the heat-insulating material. However, if the shape of the locking ring 202 becomes larger, more material will be required. The cost of the heat-insulating material is lower than that of the materials that make up the locking ring 202. This solution is suitable for small heat-insulating layers, which require less material.

[0044] This device can select bidirectional locking blocks 304 of different lengths to be fitted onto the outside of the handle block 303 and the double-layer threaded rod 305 according to the length requirements of the positioning cylinder 302, and tighten them with nuts to achieve adaptive adjustment. Finally, the piston rod 307 is pushed to spray the glue in the glue storage tube 311 through the L-shaped spray tube 310 to the connection between the heat insulation airbag 201 and the heat insulation cavity 104, enhancing adhesion and sealing. When the heat insulation airbag 201 expands due to heat, it applies a clamping force to the positioning cylinder 302, while the L-shaped spray tube 310 restricts its outward movement; when it contracts due to cold, the side wall limiting of the locking groove 312 and the glue adhesion work together to reduce the effects of thermal expansion and contraction.

[0045] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
