Description

Technical Field

[0001] This utility model belongs to the field of building envelope technology, and more specifically, it relates to an adaptive thermal insulation and light-adjusting integrated curtain wall structure for cold regions. Background Technology

[0002] The adaptive thermal insulation and light-regulating integrated curtain wall for cold regions is a passive building envelope structure adapted to harsh climates. Its core feature is "environmental response and functional self-adjustment," integrating multiple functions such as thermal insulation, dynamic shading, and natural ventilation. Through the coordinated action of structural components, it achieves real-time adaptation to outdoor temperature and solar radiation. It is a key technology carrier for building energy conservation in cold northern regions. Its core design concept revolves around "low energy consumption and high durability." Unlike traditional fixed curtain walls, it can actively adjust the panel posture and insulation layer status to balance building lighting needs and heating energy consumption, aligning with current green building development trends. Existing curtain wall technology can no longer meet the dual needs of enterprises for cost reduction and efficiency improvement as well as engineering quality improvement. Specific problems are clearly targeted in enterprise operation and actual production. From the enterprise's perspective, the primary pain point is the contradiction between cost and reliability: traditional adaptive curtain walls rely heavily on electronic control sensors and drive motors, and the equipment cost is significantly higher than that of ordinary curtain walls. In addition, additional costs are required for customized algorithm development. Furthermore, the low temperature environment in frigid regions will cause the failure rate of electronic control components to increase significantly, far exceeding the stability level of traditional curtain walls, which will greatly increase the enterprise's later operation and maintenance costs.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an adaptive thermal insulation and dimming integrated curtain wall structure for cold regions, in order to achieve a more practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adaptive thermal insulation and light-regulating integrated curtain wall structure for cold regions, achieved through the following specific technical means: An adaptive thermal insulation and dimming integrated curtain wall structure for cold regions includes a curtain wall body. From the outside to the inside, the curtain wall body is provided with a movable sunshade and a composite insulation board layer. The movable sunshade is connected to the frost-resistant floating foundation through a keel. The base of the movable sunshade is rotatably connected to the keel through a universal adapter. A thermo-bending drive is installed on one side of the universal adapter, which drives the movable sunshade to rotate around the universal adapter. The inner side of the movable sunshade is fixedly connected to the composite insulation board. When the movable sunshade opens and closes, it causes the composite insulation board to deform through pores. The movable sunshade is dynamically sealed between multiple layers of extruded sealing strips.

[0005] Preferably, the movable sunshade has an arc-shaped curved surface structure with wavy interlocking parts at the edges. The interior adopts a composite structure of "FRTP substrate + hollow honeycomb core", with thermal insulation material filled inside the hollow honeycomb core. The universal adapter has a built-in memory alloy spring.

[0006] Preferably, the thermo-bending drive component is an arc-shaped structure made of composite welding of titanium alloy sheet and low carbon steel sheet. One end of the thermo-bending drive component is fixed to the keel, and the other end is snapped into the universal adapter support.

[0007] Preferably, the composite insulation board uses low-temperature resistant elastic rubber as the base material and has gradient-distributed pores inside. The composite insulation board is arranged along the length of the movable sunshade. When the movable sunshade is closed, it squeezes the composite insulation board to make its pores shrink and become dense. When the movable sunshade is opened, the composite insulation board elastically returns to its original position, and the pores expand to form a longitudinal ventilation channel.

[0008] Preferably, the frost-resistant floating foundation comprises, from top to bottom, a rubber buffer seat, a concrete cantilever slab, an XPS insulation board, and a sand and gravel cushion layer. A gap is reserved between the concrete cantilever slab and the main structural ground beam, and the gap is filled with elastic filler. The rubber buffer seat is a laminated structure of "chloroprene rubber + multi-layer steel sheet". The outer layer of the rubber buffer seat is wrapped with low-temperature resistant rubber. The top of the rubber buffer seat is connected to the keel bolt, and the bottom of the rubber buffer seat is fixed to the concrete cantilever slab.

[0009] Preferably, the multi-layer extrusion sealing strip includes a protrusion and a groove provided on the edge of the movable sun visor, and a water-stopping expansion strip is embedded inside the protrusion.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves powerless adaptive dimming and heat insulation of the curtain wall by using a movable sunshade in conjunction with a thermo-bending drive component and a universal adapter. It does not rely on an electrical control system, thus avoiding the corrosion and damage of electrical control components caused by low temperatures in cold regions, reducing the risk of failure, and reducing energy consumption, which meets the requirements of passive energy saving. By using the movable sunshade in conjunction with the composite insulation board, dynamic switching between heat insulation and ventilation functions is achieved. When closed, the insulation board has dense pores that block cold air flow, and when opened, it forms a ventilation channel to expel residual indoor heat. This solves the problem that traditional curtain walls cannot simultaneously achieve heat insulation and lighting and ventilation, and improves the comfort of the indoor thermal environment.

[0011] 2. This utility model utilizes the combined structure of each layer of the anti-frost heave floating foundation (rubber buffer seat, concrete cantilever slab, XPS insulation board, and sand and gravel cushion layer) to effectively offset the frost heave force of cold soil. The XPS insulation board blocks the conduction of negative temperature, and the elastic filler and buffer seat absorb displacement, preventing misalignment and deformation of the curtain wall keel and significantly improving the structural stability and service life of the curtain wall in severe cold environments. The combination of movable sunshade and multi-layer extrusion sealing strips (convex ridges, grooves, and water-stopping expansion strips) achieves dynamic sealing of the curtain wall joints. When closed, the interlocking and extrusion strips form multiple layers of protection. When exposed to water, the strips expand to strengthen the sealing, effectively preventing snowmelt water from seeping in, avoiding damage to the curtain wall structure caused by low-temperature freezing, and reducing operation and maintenance costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: As attached Figure 1 To be continued Figure 3 As shown: This utility model provides an adaptive thermal insulation and light-regulating integrated curtain wall structure for cold regions, including a curtain wall body 1. The curtain wall body 1 is arranged from the outside to the inside as a movable sunshade 2 and a composite insulation board layer 5. The movable sunshade 2 is connected to the frost-resistant floating foundation 6 through a keel 7. The root of the movable sunshade 2 is rotatably connected to the keel 7 through a universal adapter 3. A thermo-bending drive 4 is installed on one side of the universal adapter 3. The thermo-bending drive 4 drives the movable sunshade 2 to rotate around the universal adapter 3. The inner side of the movable sunshade 2 is fixedly connected to the composite insulation board 5. When the movable sunshade 2 is opened and closed, it causes the composite insulation board 5 to deform through pores. The movable sunshade 2 is dynamically sealed through a multi-layer extrusion sealing strip 8.

[0018] Among them, the movable sunshade 2 has an arc-shaped curved surface structure, and the edge of the movable sunshade 2 is provided with a wavy interlocking part. The interior of the movable sunshade 2 adopts a composite structure of "FRTP substrate + hollow honeycomb core". The hollow honeycomb core is filled with thermal insulation material. The universal adapter 3 has a built-in memory alloy spring 9. The arc-shaped curved surface structure of the movable sunshade 2 improves the wind load resistance, and the wavy interlocking part of the composite thermal insulation board 5 provides a structural basis for sealing. The composite structure of "FRTP substrate + hollow honeycomb core + thermal insulation filler" enhances thermal insulation performance under the premise of lightweight. The memory alloy spring 9 built into the universal adapter 3 can help adjust the rotation accuracy. The two work together to achieve the synergistic effect of "structural stability + thermal insulation base + precise movement". The benefit is that it not only improves the weather resistance of the curtain wall in cold regions, but also ensures that the movable sunshade 2 rotates flexibly and is not easy to jam, laying a structural foundation for subsequent adaptive functions.

[0019] Among them, the thermo-bending drive component 4 is an arc-shaped structure made of "titanium alloy sheet + low carbon steel sheet" composite welding. One end of the thermo-bending drive component 4 is fixed to the keel 7, and the other end is snapped to the universal adapter 3. The thermo-bending drive component 4 adopts the "titanium alloy sheet + low carbon steel sheet" composite arc-shaped structure, and realizes the non-powered deformation by utilizing the difference in thermal expansion coefficients of bimetallic materials. The power is accurately transmitted through the connection method of "one end fixed to the keel 7 and the other end universal adapter 3". The three work together to achieve the non-powered drive effect of the curtain wall. The advantage is that it does not need to rely on the electrical control system, avoids the risk of freezing damage to the circuit in cold regions, reduces the probability of failure and energy consumption, and meets the needs of passive energy saving.

[0020] The composite insulation board 5 uses low-temperature resistant elastic rubber as its base material and has gradient-distributed pores inside. The composite insulation board 5 is arranged along the length of the movable sunshade 2. When the movable sunshade 2 is closed, it squeezes the composite insulation board 5 to make its pores shrink and become dense. When the movable sunshade 2 is opened, the composite insulation board 5 elastically returns to its original position, and the pores expand to form a longitudinal ventilation channel. The composite insulation board 5 uses low-temperature resistant elastic rubber as its base material, and the gradient pore design adapts to dynamic deformation requirements. It is arranged along the length of the movable sunshade 2 to achieve full linkage. The opening and closing of the movable sunshade 2 directly controls the "shrinkage and density / expansion and ventilation" of the insulation board pores. The two work together to achieve a dynamic switching effect of "insulation-ventilation". The advantage is that it solves the functional conflict between traditional curtain wall insulation and lighting and ventilation. It strengthens insulation and heat retention at low temperatures and guides the exhaust of indoor residual heat at suitable temperatures, thereby improving the comfort of the indoor thermal environment.

[0021] The frost-heave-resistant floating foundation 6 comprises, from top to bottom, a rubber buffer seat 10, a concrete cantilever slab 12, an XPS insulation board 13, and a sand and gravel cushion layer 14. A gap is reserved between the concrete cantilever slab 12 and the main structural beam, and the gap is filled with elastic filler 15. The rubber buffer seat 10 is a "chloroprene rubber + multi-layer steel sheet" laminated structure. The outer layer of the rubber buffer seat 10 is wrapped with low-temperature resistant rubber. The top of the rubber buffer seat 10 is bolted to the keel 7, and the bottom of the rubber buffer seat 10 is fixed to the concrete cantilever slab 12. The frost-heave-resistant floating foundation 6 forms a layered protection of "buffering-bearing-insulation-improvement" from top to bottom. The rubber buffer seat 10 absorbs longitudinal deformation with its "chloroprene rubber + multi-layer steel sheet" structure. The gap between the concrete cantilever slab 12 and the ground beam and the elastic filler 15 offset lateral frost heave. The XPS insulation board 13 blocks negative temperature conduction. The sand and gravel cushion layer 14 improves the frost heave characteristics of the foundation. The bolted connection between the rubber buffer seat 10 and the keel 7 ensures uniform force transmission.

[0022] The multi-layer extrusion sealing strip 8 includes a protrusion and a groove on the edge of the movable sunshade 2. A water-stopping expansion strip 11 is embedded inside the protrusion. The protrusion and groove of the multi-layer extrusion sealing strip 8 are adapted to and interlock with the edge of the movable sunshade 2. The water-stopping expansion strip 11 inside the protrusion can deform and seal when squeezed or exposed to water. The two work together to achieve a dynamic sealing effect for the curtain wall joint. The advantage is that an effective seal can be formed when the movable sunshade 2 is opened and closed. When snow melts and water seeps in, the strip automatically expands to strengthen the seal, preventing low temperature freezing from damaging the curtain wall structure and reducing the maintenance cost of subsequent leakage repairs.

[0023] The working principle of this embodiment is as follows: First, temperature fluctuation is used as the core trigger signal. The thermal bending drive component 4 uses the difference in thermal expansion coefficient between titanium alloy sheet and low carbon steel sheet to generate bending deformation. Together with the universal adapter 3 with built-in memory alloy spring sheet 9, it drives the arc-shaped movable sunshade 2 to rotate around the keel 7 to open and close. During the rotation of the movable sunshade 2, the inner composite insulation board 5 is linked. When it closes, it squeezes the insulation board to make its gradient pores shrink and become dense to enhance the insulation. When it opens, it drives the insulation board to elastically reset and make the pores expand to form a ventilation channel to assist heat dissipation. At the same time, the wavy interlocking part of the edge of the movable sunshade 2 cooperates with the convex edge, groove and water-stop expansion strip 11 of the multi-layer extrusion sealing strip 8 to achieve dynamic sealing. The anti-freeze floating foundation 6 provides stable support for the entire curtain wall system through the synergistic effect of each layer of structure, ensuring that the operation of each component is accurate and reliable in low temperature environment.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
