Description

Technical Field

[0001] This invention relates to the field of external wall insulation structure technology, and in particular to an external wall insulation structure for near-zero energy buildings. Background Technology

[0002] External wall insulation is a construction method that involves pasting or anchoring insulation materials to the outside of a building wall, and it has a good effect on building energy conservation.

[0003] In the prior art, such as Chinese Patent No. CN214246162U, a convenient external wall insulation structure is disclosed. This structure includes a wall, with a connecting frame on the outdoor side of the wall. Multiple insulation boards are placed within the connecting frame, and a positioning block is located on the side of the connecting frame near the insulation boards. A positioning groove is formed on the side of the insulation boards near the connecting frame, and the positioning block is inserted into the positioning groove. This patent effectively improves upon the inconvenience of constructing external wall insulation structures.

[0004] In the above technical solution, the connecting frame with the insulation board and mesh cloth is fixed to the side wall of the wall with adhesive. Then, a smoothing layer is applied to the mesh cloth, and finally the second wall panel is fixed on the smoothing layer to complete the construction. When using adhesive to fix the connecting frame, adhesive needs to be applied to one side of the connecting frame before bonding. Since the connecting frame with the insulation board is large, the installation position of the connecting frame is prone to inaccuracy and its large size makes operation inconvenient, affecting the installation of the external wall insulation structure.

[0005] Based on this, an external wall insulation structure for near-zero energy consumption buildings is proposed. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes an external wall insulation structure for near-zero energy consumption buildings.

[0007] The technical solution for achieving the purpose of this invention is: an external wall insulation structure for near-zero energy buildings, comprising a wall, wherein an installation cavity is fixedly connected to one side of the wall, and further comprising:

[0008] A connecting frame, wherein a positioning groove is provided through one side of the connecting frame, and two fastening grooves are provided on the inner wall of the positioning groove;

[0009] A positioning block is fixedly installed on one side of the mounting cavity. Two trapezoidal fastening blocks are slidably arranged on the inner wall of the positioning block. A protrusion is slidably connected to the inner wall of the positioning block. A rotating rod is rotatably connected to the inner wall of the mounting cavity. A rotating block is fixedly connected to the surface of the rotating rod. Multiple driving ball rods are fixedly connected to the surface of the rotating block. A baffle is fixedly connected to the inner wall of the mounting cavity. A sliding hole is opened on the upper surface of the baffle. A spherical rod is slidably connected to the inner wall of the sliding hole. A trapezoidal driving block is fixedly connected to the top of the spherical rod. A connecting plate is fixedly connected to one side of the protrusion. A trapezoidal force-bearing block is fixedly connected to one side of the connecting plate. A spring is sleeved on the surface of the spherical rod.

[0010] Insulation board, which is detachably connected inside the connecting frame.

[0011] Preferably, a groove is formed on one inner wall of the positioning block, and a slide rod is fixedly connected to the inner wall of the groove. Two sliders are slidably connected to the surface of the slide rod, and one side of each of the two sliders is fixedly connected to one side of the corresponding two trapezoidal fastening blocks.

[0012] Preferably, a second spring is sleeved on the surface of the slide rod, and the two ends of the second spring are respectively fixedly connected to the opposite surfaces of two trapezoidal fastening blocks, and the two sliders are respectively slidably connected to the inner wall of the slide groove.

[0013] Preferably, a rotating groove is provided on one side of the wall, a limit ring is fixedly connected to the inner wall of the rotating groove, a threaded groove is provided on one side of the rotating groove, a threaded rod is fixedly connected to one end of the rotating rod, the surface of the threaded rod is detachably threaded to the inner wall of the threaded groove, and a hexagonal socket is fixedly connected to one end of the rotating rod.

[0014] Preferably, the insulation board has a rotating disk in the middle groove on its side, and two fixing plates are fixedly connected inside the middle groove.

[0015] Preferably, each of the two fixed plates is provided with a limit block on its side, and a spring is fixedly connected between the surface of the two limit blocks and the fixed plate. A pull rope is connected between the side of the limit block and the rotating disk, and the pull rope is wound around the rotating disk.

[0016] Preferably, the inner wall of the connecting frame is provided with a limiting groove, and the inner wall of the limiting groove is adapted to slide and connect with the surface of the limiting block.

[0017] Preferably, a plurality of anchor bolts are provided on one side of the mounting cavity, and the wall and the mounting cavity are fixedly connected by the plurality of anchor bolts. The outer surface of the insulation board is provided with a mesh cloth, the side of the mesh cloth is provided with a flat layer, and the side of the flat layer is provided with a wall panel.

[0018] The significant advantages of this invention compared to existing technologies are:

[0019] Firstly, this invention involves aligning the positioning groove of the connecting frame with the positioning block and inserting it. Then, a tool is used to rotate the inner hexagon at the end of the rotating rod, causing the rotating block and the driving ball rod to rotate. The driving ball rod pushes the spherical rod upward along the sliding hole of the baffle, compressing the third spring. The trapezoidal driving block at the top of the spherical rod pushes upward, and the trapezoidal force block connected to the protrusion is driven by the inclined plane, pushing the protrusion to move outward. The protrusion squeezes the two trapezoidal fastening blocks, causing them to overcome the elastic force of the second spring and slide along the sliding rod to both sides. The trapezoidal fastening blocks are inserted into the fastening groove on the inner wall of the positioning groove, achieving rigid locking. This enables multi-directional stable locking of the connecting frame in a single operation, improving connection stability and convenience.

[0020] Secondly, when the trapezoidal fastening block is driven to rotate the hexagonal internal hexagon, the threaded rod is screwed into the threaded groove, thereby limiting the position of the threaded rod. This can prevent the hexagonal internal hexagon from rotating on its own after positioning the trapezoidal fastening block, thus affecting stability.

[0021] Thirdly, when the limiting position on the connecting frame is removed, the internal hexagon can be reversed to disengage the threaded rod from the threaded groove. At this time, the end of the threaded rod is blocked by the limiting ring inside the rotating groove, which can prevent the rotating rod from disengaging from the threaded rod from the rotating groove, thereby affecting the assembly of the connecting frame.

[0032] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0033] This invention provides an improved external wall insulation structure for near-zero energy buildings. The technical solution of this invention is as follows:

[0034] like Figures 1-7 As shown, an external wall insulation structure for near-zero energy buildings includes a wall 1, which is the main load-bearing structure of the building and provides an installation base for the insulation system. The wall 1 is made of conventional concrete blocks or reinforced concrete with a smooth surface treatment to ensure the fit of the installation cavity 2. The installation cavity 2 is fixedly connected to one side of the wall 1. The installation cavity 2 is a metal frame pre-fixed to the wall 1, serving as the carrier of the mechanical locking system. It is made of galvanized steel plate, combining strength and corrosion resistance. It is rigidly connected to the wall 1 by anchor bolts 14 to ensure wind pressure resistance. The structure also includes:

[0035] The connecting frame 3 has a positioning groove 21 through one side. The inner wall of the positioning groove 21 has two fastening grooves 22. The connecting frame 3 is a metal frame that accommodates the insulation board 7. The positioning groove 21 and fastening groove 22 on the side wall realize mechanical locking. It uses thermally broken aluminum alloy profile to reduce the thermal bridge effect. The inner wall is provided with a limiting groove 13.

[0036] Positioning block 15 serves as a guide and locking hub. It is inserted into the positioning groove 21 of the connecting frame 3, triggering a linkage. Positioning block 15 is fixedly installed on one side of the mounting cavity 2. Two trapezoidal fastening blocks 19 are slidably arranged on the inner wall of positioning block 15. These trapezoidal fastening blocks 19 are locking actuators; after being pressed by protrusion 20, they are snapped into the fastening groove 22. They are made of hard aluminum alloy, with an inclined surface angle to optimize force transmission. The inner wall of positioning block 15 is slidably connected to protrusion 20, and the inner wall of the mounting cavity 2 is rotatably connected to rotating rod 2. 7. A rotating block 24 is fixedly connected to the surface of the rotating rod 27. Multiple driving ball rods 25 are fixedly connected to the surface of the rotating block 24. A baffle 33 is fixedly connected to the inner wall of the mounting cavity 2. A sliding hole is opened on the upper surface of the baffle 33. A ball rod 26 is slidably connected to the inner wall of the sliding hole. A trapezoidal driving block 35 is fixedly connected to the top of the ball rod 26. A connecting plate 32 is fixedly connected to one side of the protrusion 20. A trapezoidal force-bearing block 36 is fixedly connected to one side of the connecting plate 32. A spring 34 is sleeved on the surface of the ball rod 26.

[0037] Insulation board 7 is detachably connected inside the connecting frame 3.

[0038] like Figure 3 and Figure 4 As shown, a groove is provided on one side of the inner wall of the positioning block 15. A slide rod 16 is fixedly connected to the inner wall of the groove. Two sliders 17 are slidably connected to the surface of the slide rod 16. One side of each slider 17 is fixedly connected to one side of a corresponding trapezoidal fastening block 19.

[0039] A second spring 18 is fitted on the surface of the slide rod 16. The two ends of the second spring 18 are fixedly connected to the opposite surfaces of two trapezoidal fastening blocks 19, and the two sliders 17 are slidably connected to the inner wall of the slide groove.

[0040] like Figure 6 As shown, a rotating groove 29 is provided on one side of the wall 1. A limit ring 31 is fixedly connected to the inner wall of the rotating groove 29. A threaded groove 30 is provided on one side of the rotating groove 29. A threaded rod 28 is fixedly connected to one end of the rotating rod 27. The surface of the threaded rod 28 is detachably connected to the inner wall of the threaded groove 30. A hexagonal socket 23 is fixedly connected to one end of the rotating rod 27. The threaded rod 28 cooperates with the threaded groove 30 of the wall 1 to prevent self-rotation after locking. The limit ring 31 (nylon material) prevents the rotating rod 27 from coming off.

[0041] like Figure 5 and Figure 6 As shown, a rotating disk 8 is provided in the middle groove on the side of the insulation board 7, and two fixing plates 9 are fixedly connected inside the middle groove.

[0042] Limiting blocks 11 are provided on the sides of both fixed plates 9. Springs 10 are fixedly connected between the surfaces of the two limiting blocks 11 and the fixed plates 9. Pull ropes 12 are connected between the sides of the limiting blocks 11 and the rotating disk 8. The pull ropes 12 are wound around the rotating disk 8. The rotating disk 8 is made of engineering plastic and is wear-resistant. The limiting blocks 11 are spring steel sheets (galvanized for rust prevention) and are ejected by springs 10. The pull ropes 12 are nylon-coated steel wire ropes to ensure durability under repeated stretching.

[0043] A limiting groove 13 is provided on the inner wall of the connecting frame 3, and the inner wall of the limiting groove 13 is adapted to slide and connect with the surface of the limiting block 11.

[0044] like Figure 1 and Figure 2 As shown, a plurality of anchor bolts 14 are provided on one side of the installation cavity 2. The wall 1 and the installation cavity 2 are fixedly connected by a plurality of anchor bolts 14. The outer surface of the insulation board 7 is provided with a mesh cloth 4. A flat layer 5 is provided on the side of the mesh cloth 4. A wall panel 6 is provided on the side of the flat layer 5.

[0045] The mesh fabric 4, the leveling layer 5, and the wall panel 6 in this application have all been disclosed in Chinese Patent No. CN214246162U, and will not be described in detail here.

[0046] The specific working method is as follows: When in use, a rotating disk 8 is installed in the middle groove on the side of the insulation board 7. A pull rope 12 is wound on the disk, and the other end of the pull rope 12 is connected to a limiting block 11. By rotating the rotating disk 8, the spring 10 can be compressed, and the limiting block 11 is pulled into the middle groove, embedding the insulation board 7 into the connecting frame 3. When the insulation board 7 is fully inserted, the rotating disk 8 is reversed, the pull rope 12 is released, and the limiting block 11 pops out under the action of the spring 10 and is locked into the limiting groove 13 on the inner wall of the connecting frame 3 to complete the fixation. Rotating the rotating disk 8 tightens the pull rope 12, pulling the limiting block 11 to retract and disengage from the limiting groove 13, and the insulation board 7 can be taken out.

[0047] The wall 1 is fixed to the mounting cavity 2 by anchor bolts 14. The positioning block 15 is fixed on the outside of the mounting cavity 2. The positioning groove 21 of the connecting frame 3 is aligned with the positioning block 15 and inserted. Then, the internal hexagon 23 at the end of the rotating rod 27 is rotated with a tool, which drives the rotating block 24 and the driving ball rod 25 to rotate. The driving ball rod 25 pushes the ball rod 26 to move upward along the sliding hole of the baffle 33, compressing the spring 34. The trapezoidal driving block 35 at the top of the ball rod 26 is pushed upward. The trapezoidal force block 36 connected to the protrusion 20 is driven by the inclined plane, pushing the protrusion 20 to move outward. The protrusion 20 squeezes the two trapezoidal fastening blocks 19, so that it overcomes the elastic force of the spring 28 and slides to both sides along the sliding rod 16. The trapezoidal fastening blocks 19 are inserted into the fastening groove 22 on the inner wall of the positioning groove 21 to achieve rigid locking. Thus, a single operation can achieve multi-directional stable locking of the connecting frame 3, improving the connection stability and convenience.

[0048] When the trapezoidal fastening block 19 is driven to rotate the hexagonal socket 23, the threaded rod 28 is screwed into the threaded groove 30, thus limiting the threaded rod 28. This prevents the hexagonal socket 23 from rotating after positioning the trapezoidal fastening block 19, which would affect stability. When the limiting of the connecting frame 3 is removed, the hexagonal socket 23 is reversed, which allows the threaded rod 28 to disengage from the threaded groove 30. At this time, the end of the threaded rod 28 is blocked by the limiting ring 31 inside the rotating groove 29, which prevents the rotating rod 27 from disengaging from the threaded rod 28.

[0049] The technical means disclosed in this invention are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this invention are common knowledge to those skilled in the art.
