Description

Technical Field

[0001] This invention relates to the field of building wall insulation structure technology, specifically to a thermal insulation building wall structure based on a steel-wood composite structure. Background Technology

[0002] In the construction industry, walls, as a crucial component of buildings, not only bear the functions of load-bearing and enclosure but also have a key impact on the building's thermal insulation performance. With people's increasing demands for building comfort and energy efficiency, developing wall structures with excellent thermal insulation properties has become particularly important.

[0003] Traditional building walls, such as brick-concrete structures, while possessing a certain degree of strength and stability, have limited thermal insulation performance and ease of assembly, making it difficult to meet the requirements of modern building energy efficiency standards. Furthermore, the dimensions of some existing prefabricated insulated wall structures are generally custom-made, making it difficult to flexibly adjust the wall width as needed. Simultaneously, the internal thermal insulation structure is relatively simple, failing to adequately insulate against external heat in high-temperature areas. This leads to the wall's own temperature rising and being difficult to lower, continuously increasing indoor temperature. Conversely, in low-temperature areas, the wall's temperature drops continuously, resulting in weakened insulation performance and poor user comfort. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal insulation building wall structure based on a steel-wood composite structure that allows for flexible size adjustment while also assisting in efficient temperature control of the wall, thereby solving the problems mentioned in the background art.

The first frame has fixed brackets fixedly connected to its upper and lower sides. The adjustment mechanism includes two sets of sliding rods fixedly installed on the side of the second frame. The adjustment mechanism can adjust the relative sliding opening and closing of the first and second frames, thereby adjusting the overall width of the wall structure. The thermal insulation mechanism includes multiple sets of conveying pipes installed on the first and second frames. The conveying pipes are in a serpentine bend. The thermal insulation mechanism can control the communication state between the multiple sets of conveying pipes and adjust the internal liquid conveying state, achieving auxiliary thermal insulation and temperature control functions. This facilitates flexible size adjustment while also assisting in efficient temperature control of the wall.

[0006] Preferably, the adjustment mechanism further includes four sets of first mounting rods fixedly installed on the sides of the two sets of fixed frames, and two sets of second mounting rods fixedly connected to the upper and lower sides of the second frame.

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-12 This invention provides a technical solution: a thermally insulated building wall structure based on a steel-wood composite structure, comprising a first frame 1, a second frame 2, an adjustment mechanism, and a thermal insulation mechanism. The first frame 1 has fixed brackets 3 fixedly connected to its upper and lower sides respectively. A first wooden board 42 is fixedly connected inside the first frame 1, and a second wooden board 43 is fixedly connected inside the second frame 2. The first wooden board 42 can slide against the second wooden board 43. The adjustment mechanism includes two sets of sliding rods 4 fixedly installed on the side of the second frame 2. The adjustment mechanism can adjust the relative sliding opening and closing of the first frame 1 and the second frame 2, thereby adjusting the overall width of the wall structure. The thermal insulation mechanism includes multiple sets of conveying pipes 5 installed on the first frame 1 and the second frame 2. The conveying pipes 5 are in a serpentine bend shape. The thermal insulation mechanism can control the communication state between the multiple sets of conveying pipes 5 and adjust the conveying state of the internal liquid, achieving auxiliary thermal insulation and temperature control functions.

[0032] The adjustment mechanism also includes four sets of first mounting rods 6 fixedly installed on the sides of the two sets of fixed frames 3 respectively. Two sets of second mounting rods 7 are fixedly connected to the upper and lower sides of the second frame 2 respectively. Multiple sets of first connecting rods 8 fixedly connected to the upper first mounting rod 6 are evenly fixedly connected to the lower first mounting rod 6. Multiple sets of second connecting rods 9 fixedly connected to the upper second mounting rod 7 are evenly fixedly connected to the lower second mounting rod 7. The spacing between adjacent first connecting rods 8 and the spacing between adjacent second connecting rods 9 are the same as the width of the first connecting rod 8 and the second connecting rod 9 respectively. The conveying pipe 5 is fixedly installed inside the first connecting rod 8 and the second connecting rod 9.

[0033] The adjustment mechanism also includes a device box 10 fixedly installed on the fixed frame 3. An adjustment groove 11 is provided in the device box 10. An adjustment block 12 is slidably connected in the adjustment groove 11 along the horizontal direction. A guide rod 13 is fixedly connected to the sliding rod 4 and slidably connected to the bottom surface of the adjustment block 12 along the horizontal direction. A control component 14 is provided in the device box 10 for adjusting the position of the sliding rod 4 and connecting the two conveying pipes 5 on both sides.

[0034] The control component 14 includes a threaded rod 15 rotatably connected to the device box 10. The threaded rod 15 passes through the adjusting block 12 and is threadedly connected to the adjusting block 12. A first pipe 16 is connected between the two sets of conveying pipes 5 near the first frame 1. The first pipe 16 passes through the adjusting block 12 and is slidably connected to the adjusting block 12. A second pipe 17 is connected between the two sets of conveying pipes 5 near the second frame 2. The adjusting block 12 is provided with a connecting component 18 for controlling the communication state between the first pipe 16 and the second pipe 17.

[0035] The connecting component 18 includes a flexible tube 19 fixedly installed on the second pipe 17. The adjusting block 12 has a connecting hole 20. The bottom of the first pipe 16 has a side hole 21 that can communicate with the connecting hole 20. The two ends of the flexible tube 19 are respectively connected to the connecting hole 20 and the second pipe 17. The sliding rod 4 and the guide rod 13 both have a placement groove 22, and the flexible tube 19 is located in the placement groove 22.

[0036] The thermal insulation mechanism also includes a storage tank 23 installed underground. The storage tank 23 is used to store liquid. The two ends of the storage tank 23 are respectively connected to a third pipe 24 and a fourth pipe 25. The two sets of delivery pipes 5 near the first frame 1 are connected to the third pipe 24, and the two sets of delivery pipes 5 near the second frame 2 are connected to the fourth pipe 25. An electric telescopic rod 40 is fixedly connected inside the storage tank 23. The telescopic end of the electric telescopic rod 40 is fixedly connected to a drive plate 41, and the drive plate 41 is slidably connected to the inner wall of the storage tank 23.

[0037] The first frame 1 and the fixing frame 3 are both provided with sliding grooves 27 on their sides. A sliding frame 28 is slidably connected in the sliding groove 27. A push plate 29 is slidably connected in the sliding groove 27. A spring 30 is fixedly connected to the side of the push plate 29. The end of the spring 30 away from the push plate 29 is fixedly connected to the side of the sliding frame 28. The threaded rod 15 is provided with a drive component 31 for automatically controlling the sliding frame 28 to slide out when the second frame 2 is limited, thereby improving the sealing performance of the connection.

[0038] The driving component 31 includes a worm gear 32 coaxially fixedly mounted on a threaded rod 15. A rotating rod 33 is rotatably connected inside the fixing frame 3. One end of the rotating rod 33 is coaxially fixedly connected to a worm wheel 34, which meshes with the worm gear 32. The end of the rotating rod 33 away from the worm wheel 34 is coaxially fixedly connected to a lead screw 35, which passes through the push plate 29 and is threadedly connected to the push plate 29. A driving shaft 36 is rotatably connected inside a set of first connecting rods 8. Both ends of the driving shaft 36 are coaxially fixedly connected to a first bevel gear 37. One end of the worm gear 32 is coaxially fixedly connected to a rotating block 38. A second bevel gear 39 is fixedly connected to the rotating block 38, and the second bevel gear 39 meshes with the first bevel gear 37.

[0039] Working principle: By rotating any one set of rotating blocks 38, the second bevel gear 39 is driven to rotate the first bevel gear 37 and the drive shaft 36, thereby driving the other set of second bevel gears 39 and rotating blocks 38 to rotate. This allows the threaded rods 15 and worm gears 32 on both sides to rotate synchronously. First, adjust the adjusting block 12 to the end away from the rotating block 38. At this time, the adjusting block 12 will drive the guide rod 13 and the sliding rod 4 to slide together, so that the first connecting rod 8 and the second connecting rod 9 are not interlocked. Then, by horizontally pushing and pulling the second frame 2, the distance between the second frame 2 and the first frame 1 can be changed, and the width of the wall can be adjusted to be close to the required size. Then, rotate the rotating block 38 in the opposite direction, so that the adjusting block 12 drives the guide rod 13 and the sliding rod 4 to slide to one side of the rotating block 38. The second mounting rod 7 drives the second connecting rod 9 to slide to the side of the first connecting rod 8, and finally inserts the second connecting rod 9 into the gap between the adjacent first connecting rods 8, thus completing the adjustment of the wall width.

[0040] It is worth noting that because the gap between the first connecting rods 8 is fixed, the adjustment range of the wall is stepped rather than infinitely adjustable. However, due to the small gap, the adjustment range will not produce excessive errors. At the same time, the worm gear 32 drives the worm wheel 34 to rotate, and the worm wheel 34 drives the rotating rod 33, which causes the lead screw 35 to push the push plate 29 to slide. The push plate 29 pushes the sliding frame 28 to slide to the side through the spring 30, which can expand the width of the wall structure to a certain extent, reduce the gap between adjacent walls, and cover the areas that are difficult to cover by the stepped adjustment. After the adjustment is completed, the first connecting rod 8 and the second connecting rod 9 are inserted and fixed to each other, and the surface is relatively flat. Wood veneer panels can be installed on the surface of the wall structure to beautify the wall.

[0041] During the above adjustment process, the second wooden board 43 will slide open and close along with the second frame 2, and after reaching the required width range, it will move closer to the first wooden board 42 along with the second frame 2. Finally, the first wooden board 42 and the second wooden board 43 will be in a state of mutual contact, so that the wall structure presents a three-layer composite structure with the first connecting rod 8 and the second connecting rod 9 on both sides being relatively flat and interlocking with each other, and the first wooden board 42 and the second wooden board 43 in the middle being separated by mutual contact. The first frame 1, the second frame 2, and the first connecting rod 8 and the second connecting rod 9 are all made of steel, which can improve the overall strength and stability of the structure. The first wooden board 42 and the second wooden board 43 inside can assist in heat insulation and heat dissipation.

[0042] In use, by burying a storage tank 23 underground, the temperature of the liquid inside the storage tank 23 is controlled by the ground surface. Heat is transferred to the liquid in the delivery pipe 5 through the first connecting rod 8 and the second connecting rod 9. When the temperature of the liquid in the delivery pipe 5 rises to the set value, the electric telescopic rod 40 is activated to control the drive plate 41 to slide to one side, pushing the low-temperature liquid in the storage tank 23 into the delivery pipe 5. At the same time, the high-temperature liquid in the delivery pipe 5 is drawn from the other end into the storage tank 23, continuing to use the underground environment for automatic temperature control. No auxiliary temperature control operation is required, saving energy. One set of storage tanks 23 can be connected to multiple sets of delivery pipes 5 according to their capacity to transport fluid, thereby greatly changing the temperature state inside the wall and achieving efficient auxiliary temperature control and heat dissipation, avoiding the continuous rise of indoor temperature. Similarly, when the wall temperature is too low, since the underground temperature is relatively constant, the temperature inside the storage tank 23 will be higher than the temperature of the liquid inside the wall. At this time, liquid circulation will assist in heating the liquid in the delivery pipe 5, thereby raising the overall temperature of the wall and improving the thermal insulation performance of the wall.

[0043] During the disassembly and assembly process, the sliding rod 4 and guide rod 13 on the second frame 2 can be inserted into the adjusting block 12 and pushed in horizontally. Then, one end of the flexible tube 19 is fixed to the connecting hole 20. Next, the third pipe 24 and the fourth pipe 25 extending from the ground are connected to the bottom end of the conveying pipe 5 on one side of the first frame 1 and the second frame 2 respectively. At this time, the upper ends of the conveying pipes 5 on both sides are not connected. The adjusting block 12 is on the side away from the rotating block 38. At this time, the connecting hole 20 and the side hole 21 are not connected. The inner wall of the adjusting block 12 will block the side hole 21. The outer wall of the first pipe 16 will also block the upper end of the connecting hole 20. When the adjusting block 12 slides to the side of the rotating block 38, the first connecting rod 8 and the second connecting rod 9 gradually insert into each other. At this time, the connecting hole 20 gradually connects with the side hole 21, realizing the connection of the conveying pipes 5 on both sides. This ensures that when they are not connected, no liquid will flow out of the side hole 21 on the first pipe 16, and no fluid will be discharged from one end of the flexible tube 19.

[0044] When adjusting the distance between the first frame 1 and the second frame 2, the flexible tube 19 will be bent in the placement groove 22, thereby ensuring that the connecting hole 20 is always connected to the second pipe 17 and does not affect the sliding adjustment of the guide rod 13 on the adjusting block 12.

[0045] It should be noted that the temperature control function mentioned above refers to assisting in heating (insulating) and cooling the wall, and does not precisely regulate the temperature of the wall.
