[0012] Preferably, the connecting rod includes a first segment and a second segment. The top end of the first segment is fixedly connected to the bottom end of the first connecting seat. A tapered snap-fit ​​segment is fixedly connected between the bottom end of the first segment and the top end of the second segment. The snap-fit ​​segment snaps into the snap-fit ​​block.

[0013] Preferably, the locking block includes two symmetrically arranged movable blocks, each of which is threadedly connected to one of the two connecting screws; the two movable blocks are adapted to the opposite threads on the connecting screws, and when the connecting screws rotate, the two movable blocks move closer or further apart synchronously, locking or releasing the locking segment.

[0016] Preferably, the heat storage plate is filled with a first phase change material, and the deformable plate is embedded with deformable material on one side facing the heat storage plate. The first phase change material pushes the end face of the heat storage plate to press against the deformable material.

[0017] Preferably, the heat-conducting layer includes a heat-conducting plate fixedly connected to the heat storage plate, and a sound-insulating plate fixedly connected to one end of the heat-conducting plate away from the heat storage plate, and the decorative plate fixedly connected to the sound-insulating plate; a heat-conducting component for controlling heat conduction is provided inside the heat-conducting plate.

Through reasonable heat management and conduction control, the building maintains a stable temperature environment, improving the comfort of living or working, and reducing cooling or heating consumption, aligning with the characteristics of green buildings. Decorative panels are installed on the inner and outer sides of the prefabricated structural slab, serving decorative, aesthetic, and waterproof purposes; specific selection can be made based on actual conditions.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 8 As shown, this embodiment provides a green and energy-saving steel structure building, including a support frame 4 designed in the shape of a frame, on which prefabricated structural panels 2 serving as walls and roofs are provided, and adjacent prefabricated structural panels 2 are connected to each other through a connecting mechanism 1.

[0034] The connecting mechanism 1 includes a first connecting seat 11 and a second connecting seat 12. The fixed frame composed of the first connecting seat 11 and the second connecting seat 12 is fixedly connected around the precast structural slab 2 and fixedly connected to the supporting frame 4. Adjacent precast structural slabs 2 are connected together by a connecting component provided between the first connecting seat 11 and the second connecting seat 12.

[0035] The prefabricated structural slab 2 also includes a heat insulation layer 21, a heat storage layer 22 and a heat conduction layer 23 arranged in sequence, with the heat insulation layer 21 located on the outdoor side and the heat conduction layer 23 located on the indoor side.

[0036] Decorative panels 3 are respectively snapped and fixed on the outdoor side of the insulation layer 21 and the indoor side of the heat-conducting layer 23.

[0037] This invention discloses a green and energy-saving steel structure building. The supporting frame 4 is assembled from metal materials and serves as the main structure of the building. Precast structural panels 2, prefabricated on-site, serve as walls and roofs, and are fixedly connected to the supporting frame 4 via connecting components. This method is convenient and quick, reducing on-site construction work, construction time, and construction costs. The connecting components consist of a first connecting seat 11 and a second connecting seat 12, which are fixedly connected around the precast structural panels 2 and form a fixed frame fixed to the supporting frame 4. Adjacent precast structural panels 2 are also connected by connecting components between the first connecting seat 11 and the second connecting seat 12, achieving a quick and stable connection between the precast structural panels 2 and the supporting frame 4, as well as between adjacent precast structural panels 2. This greatly improves construction efficiency, ensures construction quality, and enables the building to achieve resource conservation, environmental friendliness, and energy consumption reduction throughout its entire life cycle, meeting the requirements of green energy conservation. The precast structural panels 2 have a multi-layer structure, including a heat insulation layer 21, a heat storage layer 22, and a heat conduction layer 23, wherein the heat insulation layer 21 is located on the outdoor side, and the heat conduction layer 23... Located on the indoor side, the prefabricated structural slab 2 incorporates an insulation layer 21, a heat storage layer 22, and a heat conduction layer 23. This design significantly enhances the building's insulation performance and the efficiency of heat storage and utilization. The insulation layer 21 effectively blocks outdoor heat from entering the room, while the heat storage layer 22 stores and releases heat under different weather conditions. The heat conduction layer 23 ensures a uniform distribution of indoor temperature. When the indoor temperature is low, the heat in the heat storage layer 22 is transferred to the heat conduction layer 23, increasing the indoor temperature and reducing heating consumption. When the outdoor temperature is too high, the insulation layer 21 reduces the inflow of outdoor heat. Simultaneously, the heat storage layer 22 stores heat for convenient nighttime heating. The insulation layer 21 also reduces the outflow of indoor heat, minimizing heat loss. Through reasonable heat management and conduction control, the building's interior maintains a stable temperature environment, improving the comfort of living or working, and reducing cooling or heating consumption, thus conforming to the characteristics of green buildings. Decorative panels 3 are installed on the inner and outer sides of the prefabricated structural slab 2, serving decorative, aesthetic, and waterproof purposes. Specific selection can be made according to actual conditions. This invention is easy to install and maintain. Its modular design improves on-site construction efficiency, reduces construction difficulty and costs, enhances the building's thermal insulation performance, reduces indoor cooling and heating consumption during use, and meets the requirements of green building energy conservation and emission reduction.

[0038] In one embodiment of the present invention, the steel structure connection nodes supporting the frame 4 adopt thermal bridging technology such as nylon thermal insulation pads to avoid energy loss caused by the "thermal bridge effect" and reduce energy consumption.

[0039] In one embodiment of the present invention, a solar power generation device can be designed on the roof, which can not only avoid direct sunlight on the roof, but also store and utilize solar energy to generate electricity, effectively recover energy, and reduce energy consumption.

[0040] In one embodiment of the present invention, a rainwater harvesting device is provided around the roof, which can be used to harvest rainwater on rainy days for greywater or other purposes, thereby reducing water waste.

[0041] The design is further optimized by including several connecting rods 13 fixed to the bottom of the first connecting seat 11. A connecting module corresponding to each connecting rod 13 is provided within the second connecting seat 12, and the connecting rods 13 engage with the connecting modules. When connecting adjacent first connecting seats 11 and second connecting seats 12, the connecting rods 13 are inserted into the connecting modules through connecting holes 19 on the second connecting seat 12 and then locked, achieving a locking connection between the first connecting seat 11 and the second connecting seat 12. This makes the connection between the precast structural slab 2 and the supporting frame 4 more stable and reliable, while also improving installation convenience.

[0042] The design is further optimized. The connection module includes a connection cavity 14 located within the second connection seat 12. Two symmetrically arranged and synchronously rotating connection screws 15 are disposed within the connection cavity 14. Several locking blocks 16 are threadedly connected between the two connection screws 15. The connection rod 13 passes through and is fixedly connected to the locking blocks 16. The connection screws 15 rotate symmetrically and in the same direction within the connection cavity 14. When the connection screws 15 rotate, the locking blocks 16 move synchronously to adjust, achieving locking and loosening between the locking blocks 16 and the connection rod 13. This enables rapid locking and loosening of the connection rod 13, further improving installation efficiency and stability, and facilitating quick assembly and disassembly.

[0043] In one embodiment of the present invention, a driven wheel 17 is fixedly sleeved on one end of the connecting screw 15, and a driving wheel 18 is driven between the two driven wheels 17. The driving wheel 18 drives the two driven wheels 17 to rotate synchronously, which in turn drives the two connecting screws 15 to rotate synchronously, thereby driving the locking block 16 to adjust. The locking block 16 locks the connecting rod 13, thereby realizing the quick connection of the first connecting seat 11 and the second connecting seat 12.

[0044] In a further optimized design, the connecting rod 13 includes a first segment 110 and a second segment 111. The top end of the first segment 110 is fixedly connected to the bottom end of the first connecting seat 11. A tapered snap-fit ​​segment 112 is fixedly connected between the bottom end of the first segment 110 and the top end of the second segment 111, and the snap-fit ​​segment 112 snaps into the snap-fit ​​block 16. The tapered snap-fit ​​segment 112 is machined in the middle of the connecting rod 13, dividing the connecting rod 13 into the first segment 110 and the second segment 111. During connection, the snap-fit ​​segment 112 is located in the connecting cavity 14 and is snapped in place by the snap-fit ​​block 16, connecting the first connecting seat 11 and the second connecting seat 12 together. This design, through the tapered snap-fit ​​segment 112, makes the connection between the connecting rod 13 and the snap-fit ​​block 16 tighter and more stable, gradually locking in place, further improving the overall structural stability.

[0045] In one embodiment of the present invention, an arc-shaped head 116 is fixedly connected to the bottom end of the second segment 111 to facilitate guidance, improve positioning accuracy, and facilitate the insertion of the connecting rod 13 into the connecting hole 19.

[0046] In one embodiment of the present invention, a contact spring 118 is fixedly connected to the bottom end of the connecting hole 19, and a contact block 117 adapted to and abutting against the arc-shaped head 116 is fixedly connected to the top end of the contact spring 118. When the locking block 16 locks the connecting rod 13, the arc-shaped head 116 presses down on the contact block 117, compresses the contact spring 118, and realizes the positioning of the connecting rod 13, preventing the connecting rod 13 from shaking and improving stability. At the same time, when not connected, the contact block 17 blocks the position of the connecting hole 19 under the push of the contact spring 118, preventing external debris from blocking the connecting hole 19 during transportation and indoor storage.

[0047] Further optimizing the design, the locking block 16 includes two symmetrically arranged movable blocks 113, each threadedly connected to one of the two connecting screws 15. The two movable blocks 113 are adapted to the opposing threads on the connecting screws 15. When the connecting screws 15 rotate, the two movable blocks 113 move closer or further apart synchronously, locking or releasing the locking section 112. The locking block 16 consists of two symmetrically arranged movable blocks 113, with the threads of the connecting screws 15 corresponding to the two movable blocks 113 being opposite. When the connecting screws 15 rotate, the two movable blocks 113 move closer or further apart synchronously. When the two movable blocks 113 move closer, they clamp the locking section 112, locking the connecting rod 13 and achieving a locked connection between the first connecting seat 11 and the second connecting seat 12. When the two locking blocks 113 move further apart, they release the locked locking section 112, allowing the connecting rod 13 to be released, facilitating the separation of the first connecting seat 11 and the second connecting seat 12, thus providing greater flexibility.

[0048] In one embodiment of the present invention, reference is made to the appendix. Figure 7 As shown, the connecting screw 15 is provided with a first thread 114 and a second thread 115 with opposite directions of rotation. The two movable blocks 113 are respectively threaded to the first thread 114 and the second thread 115. When the connecting screw 15 rotates, the first thread 114 and the second thread 115 push the two movable blocks 113 to move synchronously, so that the two movable blocks 113 move closer or further apart symmetrically, engaging or releasing the engaging section 112.

[0049] In a further optimized design, the insulation layer 21 includes a base plate 24 for fixing the decorative panel 3. An insulation plate 25 is fixedly attached to the side of the base plate 24 facing the interior, and a reflective layer 26 is fixedly attached to the end of the insulation plate 25 away from the base plate 24. The reflective layer 26 is fixedly attached to the heat storage layer 22. The base plate 24 serves as the outer foundation structure of the insulation layer 21, protecting the internal insulation layer 21 and reflective layer 26 from damage to structural integrity and insulation performance. It also serves as the connection base for the decorative panel 3, preventing damage to insulation performance during connection. The insulation plate 25 and reflective layer 26 improve the insulation performance of the insulation layer 21. Furthermore, the reflective layer 26 can reflect heat loss from the interior to the heat storage layer 22 when the outdoor temperature is low, reducing heat loss and heating consumption, thus further improving the building's energy efficiency.

[0050] In one embodiment of the present invention, the reflective layer 26 is oriented towards the interior to reduce heat loss in the interior.

[0051] In one embodiment of the present invention, a first cavity 27 is provided in the heat insulation plate 25, and the first cavity 27 is filled with heat insulation gas 28 with low heat conduction efficiency. When the outdoor temperature is high, the heat insulation gas 28 expands due to heat, which makes the first cavity 27 thicker and the thickness of the heat insulation plate 25 greater. At the same time, the density of the heat insulation gas 28 decreases, thereby reducing the heat conduction efficiency and improving the heat insulation effect.

[0052] In one embodiment of the present invention, when heat is transferred within the heat insulation plate 25, the contact thermal resistance between the two interfaces of the first cavity 27 and the contact surface of the heat insulation gas 28 increases, which reduces the heat transfer efficiency and improves the heat insulation capacity.

[0053] In one embodiment of the present invention, the insulating gas 28 is preferably low-cost dry air or argon gas that balances performance and cost. Combined with the gas chamber separation design, it can effectively suppress convection and improve thermal efficiency.

[0054] In a further optimized scheme, the heat storage layer 22 includes a deformable plate 29 fixedly connected to the reflective layer 26, and a heat storage plate 210 fixedly connected to the side of the deformable plate 29 away from the reflective layer 26; the heat storage plate 210 is fixedly connected to the heat-conducting layer 23; a first phase change material 212 is filled in the heat storage plate 210, and a deformable material 214 is embedded in the side of the deformable plate 29 facing the heat storage plate 210, and the first phase change material 212 pushes the end face of the heat storage plate 210 and the deformable material 214 to press against each other. The heat storage plate 210 has a second cavity 211, into which the first phase change material 212 is filled. The deformable plate 29 has a storage slot 213 corresponding to the second cavity 211, into which deformable material 214 is disposed. The deformable material 214 is in elastic contact with the first phase change material 212, and the contact surface is arc-shaped. When the indoor temperature is low, the deformable material 214 expands, compressing the first phase change material 212, causing the first phase change material 212 to deform and release heat. The heat is transferred to the room through the heat-conducting layer 23. This increases the effect and efficiency of indoor heating. When the outdoor temperature is high but indoor heating is not required, outdoor heat is transferred to the indoor environment, the deformable material 214 shrinks, the second cavity 211 enlarges, the energy storage effect of the first phase change material 212 weakens, the phase change absorbs the surrounding heat, making the surrounding temperature lower, thereby reducing the rate at which outdoor temperature continues to transfer to the indoor environment, thus achieving the effect of lowering the room temperature. This realizes the deformation and heat storage function of the heat storage plate 210 at different temperatures, further improving the heat storage performance and stability of the heat storage layer 22.

[0055] In one embodiment of the present invention, the deformable material 214 is selected from materials that expand when cold and contract when hot, such as antimony-lead alloys or carbon fiber-resin composite materials. This is a knowledge point known to those skilled in the art and will not be elaborated here.

[0056] Further optimizing the design, the heat-conducting layer 23 includes a heat-conducting plate 215 fixedly connected to the heat storage plate 210. A sound-insulating plate 216 is fixedly connected to the end of the heat-conducting plate 215 away from the heat storage plate 210, and the decorative panel 3 is fixedly connected to the sound-insulating plate 216. A heat-conducting component for controlling heat conduction is installed within the heat-conducting plate 215. The sound-insulating plate 216 improves indoor sound insulation performance, increases living comfort, and also provides a base for installing the decorative panel 3. The heat-conducting component within the heat-conducting plate 215 controls the heat conduction capacity, achieving efficient heat conduction and control.

[0057] In one embodiment of the present invention, the sound insulation panel 216 is made of microporous concrete, which has good heat insulation and sound absorption properties, as well as good durability and safety.

[0058] Further optimization of the design includes a third cavity 217, which is vacuum-sealed within a heat-conducting plate 215. Within this cavity 217, several support columns 218 and several heat-conducting columns 219 are spaced apart. The heat-conducting columns 219 exhibit varying heat conduction efficiency at different temperatures. The vacuum design of the third cavity 217 within the heat-conducting plate 215 reduces heat transfer efficiency and improves insulation performance. The support columns 218 increase the structural strength of the third cavity 217, preventing strength reduction due to the vacuum. The varying heat conduction efficiency of the heat-conducting columns 219 at different temperatures enables the heat-conducting layer 23 to achieve efficient heat conduction and temperature control at various temperatures, further improving the building's energy efficiency and comfort.

[0059] In one embodiment of the present invention, the heat-conducting pillar 219 includes a first guide pillar 220 and a second guide pillar 221 that abut against each other; the top end of the first guide pillar 220 and the bottom end of the second guide pillar 221 are respectively fixed to the two side walls of the third cavity 217; the second guide pillar 221 is hollow and filled with a second phase change material 222; a temperature control component is provided between the first guide pillar 220 and the second guide pillar 221, the second phase change material 222 is used to store heat and facilitate heat transfer at different temperatures; and the temperature control component has different heat transfer efficiencies at different temperatures.

[0060] In one embodiment of the present invention, the temperature control component includes a sliding plate 223 that is sealed and slidably connected to the inner cavity of the second guide post 221, the bottom end of the sliding plate 223 abutting against the second phase change material 222; the top end of the sliding plate 223 extends out of the top end of the second guide post 221 and is fixedly connected to a heat-conducting block 224; the bottom end of the first guide post 220 is provided with a heat-conducting groove 225 corresponding to the heat-conducting block 224, and the heat-conducting block 224 and the heat-conducting groove 225 are detachably connected; a plurality of return springs 226 are connected between the top surface of the sliding plate 223 and the top surface of the inner cavity of the second guide post 221. When the indoor temperature is low, the first phase change material 212 releases heat, causing the second phase change material 222 to expand after contraction, pushing the heat-conducting block 224 to connect with the heat-conducting groove 225, thereby rapidly conducting heat, increasing the indoor heat, and reducing heating energy consumption; when the temperature is high, the first phase change material 212 absorbs heat, causing the second phase change material 222 to also contract, and the heat-conducting block 224 disconnects from the heat-conducting groove 225 under the action of the return spring 226, reducing the heat conduction efficiency, reducing the amount of heat from the outside entering the room, and reducing cooling energy consumption.

[0061] In one embodiment of the present invention, the first phase change material 212 includes a phase change component for absorbing and releasing heat, a nucleating agent for increasing the crystallization rate, a thermally conductive filler for transferring heat, a thickener for increasing the solution concentration, and a binder for bonding the phase change material, nucleating agent, thermally conductive filler, and thickener. The phase change component is sodium acetate trihydrate and sodium carbonate decahydrate, the nucleating agent is borax or diatomaceous earth, the thermally conductive filler is graphite or copper powder, the thickener is polyacrylic acid emulsion, and the binder is methylcellulose or sodium carboxymethyl cellulose. When exposed to high temperatures, the first phase change material 212 can rapidly absorb heat, thereby achieving a cooling effect; when exposed to low temperatures, the first phase change material 212 can rapidly release heat, thereby achieving a heating effect.

[0062] In one embodiment of the present invention, the decorative panel 3 includes an inner panel 31 and an outer panel 32. The inner panel 31 is preferably made of materials that can provide heat insulation, sound insulation and sound absorption, such as lightweight blocks, light steel keel partition wall system, inorganic fiber board (mineral wool), etc., which can also improve the aesthetics of the interior and increase the comfort of living.
