Technical Field

[0001] The present application relates to the field of wall insulation construction technology, and in particular to an insulation structure and a construction method thereof. Background Art

[0002] Walls can be divided into walls made of a single material and walls made of composite materials based on their materials or structures. They can be divided into exterior walls and interior walls based on their functions. Interior walls are mainly used to separate indoor spaces, while exterior walls are mainly used for insulation, heat insulation, sound insulation, fire prevention, and waterproofing.

[0003] At present, many houses in old communities have been built for a long time, and the exterior walls are prone to peeling and local cracking, which leads to poor indoor insulation effect. Therefore, they need to be rebuilt or the exterior walls need to be tiled for insulation modification. However, the construction period of rebuilding is long and the cost is high, and the improvement of the insulation effect by laying tiles is limited and not obvious. Summary of the invention

[0007] By adopting the above technical solution, when the construction workers renovate the exterior walls of houses in old communities, they first clean the exterior wall surface, then apply an adhesive layer on the exterior wall surface, then abut the support frame against the exterior wall surface, and adjust the installation position of the support frame by adjusting the fixed connection mechanism so that adjacent support frames are aligned horizontally and vertically along the vertical plane of the wall, then fix the position of the support frame by adjusting the fixed connection mechanism, and fill the interior of the support frame with an insulation board so that the insulation board abuts against the adhesive layer, then the construction workers repeat the above process to complete the installation of multiple support frames and insulation boards, and connect the upper and lower adjacent support frames by adjusting the fixed connection mechanism to form a The thermal insulation structure is used to renovate the exterior walls of old residential areas, and the overall load-bearing capacity of the thermal insulation structure depends on the connection between the supporting frame and the wall, so that the thermal insulation board is not easy to bear the longitudinal shear force under the gravity of the supporting frame and each structural layer, so that the thermal insulation board is not easy to crack locally, and the service life of the thermal insulation board is increased. At the same time, the installation position of the thermal insulation board and the supporting frame can be adjusted by adjusting the fixed connection mechanism, thereby improving the construction efficiency and installation convenience of the construction workers.

[0009] By adopting the above technical scheme, when the construction personnel adjust and fix the support frame by adjusting the fixing connection mechanism, first the support plate is abutted against one side of the wall, and then the longitudinal position of the support plate and the support frame along the wall plane is adjusted by the longitudinal adjustment fixing assembly, so that the multiple support frames are longitudinally aligned and fixed along the wall plane, and then the relative position of the support rod and the support frame is adjusted by the transverse adjustment fixing assembly, that is, the position of the support frame is transversely adjusted along the wall plane, so that the multiple support frames are transversely aligned and fixed along the wall plane, and at the same time, the sides of the upper and lower adjacent support frames that are close to each other are connected and fixed, and the installation of the support frame can be completed; wherein, through the mutual coordination of the support plate, the support rod, the longitudinal adjustment fixing assembly and the transverse adjustment fixing assembly, when the construction personnel install and fix the support frame, the position of the support frame can be adjusted along the transverse and longitudinal direction of the wall plane, so as to realize the rapid fixed installation of the support frame, and also the installation difficulty and installation accuracy of the support frame can be reduced, the fault tolerance rate of the construction personnel during construction can be improved, and the construction cost can be reduced.

[0012] It also includes a limiting component arranged between the driving rod and the supporting rod for limiting the rotation angle of the driving block, and an anti-loosening and anti-vibration component arranged between the driving rod and the supporting rod for limiting the rotation of the supporting rod.

[0013] By adopting the above technical scheme, when the construction workers fix the upper and lower adjacent support frames by horizontally adjusting the fixing assembly, they first insert the support rod into the support hole on the support frame, and then rotate the driving rod. The driving rod drives the driving block to rotate, so that one side of the elliptical major axis of the driving block rotates to the outside of the driving groove. At the same time, the driving block enters the sliding groove on the one hand, and on the other hand, the driving block pushes the connecting block out, so that the connecting block is inserted upward into the connecting groove at the bottom of the upper adjacent support frame, so as to realize the connection between the upper and lower adjacent support frames; wherein, when one side of the elliptical major axis of the driving block rotates to the outside of the driving groove, the driving block enters the sliding groove, and on the one hand, the driving block cooperates with the driving groove to realize the support The support frame is fixed so that the support frame cannot move along the side away from the wall. On the other hand, it drives the connecting block upward to be inserted into the connecting groove at the bottom of the upper adjacent support frame to realize the connection between the upper and lower adjacent support frames; and the driving rod can cooperate with the limiting component to control the rotation angle of the driving block, so that the construction personnel can accurately control the position of the elliptical major axis of the driving block, thereby facilitating the fixation of the support frame and the connection of the upper and lower support frames; secondly, the anti-loosening and anti-vibration component can lock the driving rod, and then the driving rod drives the driving block to rotate into the sliding groove, and then locks the driving block, so that the driving block is not easily separated from the sliding groove due to factors such as wall vibration, thereby improving the stability of the thermal insulation structure.

[0014] Optionally, the support hole is a transverse waist-shaped hole opened in the transverse direction and adapted to the support rod, and the support rod can be moved in the transverse waist-shaped hole.

[0015] By adopting the above technical solution, the transverse waist-shaped holes enable the support frame to be fine-tuned along the transverse direction of the wall plane, thereby realizing the lateral adjustment of the support frame, thereby reducing the lateral installation difficulty and installation accuracy of the support frame and improving the fault tolerance of construction workers during construction.

[0016] Optionally, the limiting component includes two first limiting blocks fixed on the side of the support rod away from the wall, and a second limiting block fixed on the outer side wall of the driving rod; the second limiting block is located between the two first limiting blocks.

[0017] By adopting the above technical solution, when the construction personnel rotate the driving rod, after the first limit block abuts against one of the second limit blocks, it means that the elliptical minor axis of the driving block coincides with the elliptical minor axis of the support rod, and at this time the support rod and the support frame are in an unlocked state; when the second limit block rotates to abut against the other first limit block, it means that the elliptical major axis of the driving block coincides with the elliptical minor axis of the support rod, and at this time the support rod and the support frame are in a locked state; the construction personnel can judge whether the support frame is in a fixed state by the abutment state of the first limit block with the two second limit blocks respectively, thereby making the construction more convenient, efficient and accurate.

[0018] Optionally, the anti-loosening and anti-vibration component includes a ratchet fixedly sleeved on the outside of the driving rod, a pawl rotatably connected to the supporting rod, a spring arranged between the pawl and the ratchet, and a control rod fixedly arranged at one end of the ratchet away from the rotating shaft thereof;

[0019] The ratchet wheel and the pawl are meshed with each other, and the spring always gives the pawl a force to approach the ratchet wheel, and one end of the control rod penetrates the support rod and is located outside the support rod.

[0020] By adopting the above technical scheme, when the staff rotates the driving rod so that the driving rod drives the elliptical long axis of the driving block to rotate into the sliding groove, the limiting component prevents the driving rod from continuing to rotate. At this time, the ratchet can only rotate in one direction under the action of the pawl, and cannot rotate to the outside of the sliding groove, so that the driving block is not easily disengaged from the sliding groove due to factors such as wall vibration, thereby improving the stability of the support frame fixation; when the support frame is aged or damaged after long-term use, the staff can move the control rod, and the control rod can drive the pawl to move, so that the pawl and the ratchet are separated, and then the driving rod is rotated in the opposite direction, so that the driving rod drives the driving block to disengage from the sliding groove, and then the connecting block can move downward under the action of gravity to disengage from the connecting groove, thereby releasing the fixation of the support frame.

[0021] Optionally, the driving block is interference fit with the side wall of the sliding groove.

[0022] By adopting the above technical solution, the interference fit, on the one hand, makes the driving block clamped into the sliding groove, so that the support frame is not easy to shake in the direction perpendicular to the wall surface, thereby firmly fixing the support frame; on the other hand, it is not easy for the driving block to move laterally along the wall surface, so that the support frame is not easy to shake laterally, thereby improving the stability of the support frame fixation.

[0023] Optionally, the longitudinal adjustment fixing assembly includes a stud expansion bolt arranged between the support plate and the wall, and a nut arranged at one end of the stud expansion bolt;

[0024] The support plate is provided with a longitudinal waist-shaped hole arranged along the longitudinal direction of the wall, one end of the stud expansion bolt passes through the longitudinal waist-shaped hole and is threadedly connected with a nut, and the nut is pressed to a side of the support plate away from the wall.

[0025] By adopting the above technical scheme, when the support plate is fixed by the longitudinal adjustment fixing component, firstly, the hole position is marked on the wall according to the installation needs, then the wall is punched, and then one end of the double-headed expansion bolt is installed into the hole opened on the wall, and then the other end of the double-headed expansion bolt is inserted into the longitudinal waist-shaped hole on the support plate, and the nut is tightened to achieve the fixation of the support plate; if the support plate is longitudinally deflected, the construction personnel can loosen the nut, adjust the installation position of the support plate up and down, and level the support plate; the installation position of the support plate and the support frame can be fine-tuned by the longitudinal adjustment fixing component, so that the construction personnel do not need to re-drill the wall after the hole position is deflected, thereby improving the fault tolerance and construction efficiency of the construction personnel during construction, and it is not easy to cause secondary damage to the wall.

[0026] Optionally, the protective layer includes a fiber mesh, a waterproof layer, and a decorative surface layer laid in sequence.

[0027] By adopting the above technical scheme, the fiber mesh is used to increase the toughness of the protective layer, so that the protective layer is not prone to local cracking, the waterproof layer is used to prevent water from entering the insulation board, thereby improving the insulation effect of the insulation board, and the decorative surface layer is used to improve the aesthetics of the protective layer and prevent the internal waterproof layer and fiber mesh from being damaged.

[0028] In a second aspect, the present application also provides a construction method of a thermal insulation structure, which is applicable to the thermal insulation structure described above, and the construction steps are as follows:

[0030] S2, applying an adhesive layer on the exterior wall surface;

[0031] S3, placing the support frame against the surface of the outer wall, and adjusting the installation position of the support frame by adjusting the fixing connection mechanism, so that adjacent support frames are aligned and fixed in the horizontal and vertical directions along the vertical plane of the wall;

[0032] S4, filling the interior of the support frame with a heat-insulating board so that the heat-insulating board is bonded to the bonding layer;

[0033] S5, repeat the above process to complete the installation of multiple support frames and insulation boards, and connect the upper and lower adjacent support frames by adjusting the fixed connection mechanism to form a whole;

[0034] S6. Lay an adhesive layer and a protective layer on the outer sides of the supporting frame and the insulation board in sequence.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The exterior wall renovation of old residential houses through the insulation structure of the present application not only shortens the construction period, saves renovation costs, and significantly improves the wall insulation effect, but also the overall load-bearing capacity of the insulation structure depends on the connection between the support frame and the wall, so that the insulation board is not easy to bear the longitudinal shear force under the gravity of the support frame and each structural layer, so that the insulation board is not easy to crack locally, and the service life of the insulation board is increased. At the same time, the installation position of the insulation board and the support frame can be adjusted by adjusting the fixed connection mechanism, thereby improving the construction efficiency and installation convenience of the construction workers;

[0037] 2. Through the coordinated use of the support plate, the support rod, the longitudinal adjustment fixing assembly and the transverse adjustment fixing assembly, when the construction personnel install the fixed support frame, they can adjust the position of the support frame along the transverse and longitudinal direction of the wall plane, so as to achieve the rapid fixed installation of the support frame, and also reduce the installation difficulty and installation accuracy of the support frame, improve the fault tolerance rate of the construction personnel during construction, and reduce the construction cost;

[0038] 3. In the lateral adjustment fixing assembly, when one side of the elliptical major axis of the driving block rotates to the outside of the driving groove, the driving block enters the sliding groove. On the one hand, the driving block cooperates with the driving groove to fix the support frame, so that the support frame cannot move along the side away from the wall. On the other hand, it drives the connecting block upward to be inserted into the connecting groove at the bottom of the upper adjacent supporting frame to achieve the connection between the upper and lower adjacent supporting frames; and the driving rod cooperates with the limiting component to control the rotation angle of the driving block, so that the construction personnel can accurately control the position of the elliptical major axis of the driving block, thereby facilitating the fixation of the support frame and the connection of the upper and lower supporting frames; secondly, the anti-loosening and anti-vibration component can lock the driving rod, and then the driving rod drives the driving block to rotate into the sliding groove, and then the driving block is locked, so that the driving block is not easily separated from the sliding groove due to factors such as wall vibration, thereby improving the stability of the thermal insulation structure;

[0039] 4. The horizontal waist-shaped holes allow the support frame to be fine-tuned along the horizontal direction of the wall plane, thereby realizing the horizontal adjustment of the support frame, thereby reducing the difficulty and accuracy of the horizontal installation of the support frame and improving the fault tolerance of the construction workers during construction;

[0040] 5. When the staff rotates the driving rod so that the driving rod drives the elliptical long axis of the driving block to rotate into the sliding groove, the limiting component prevents the driving rod from continuing to rotate. At this time, the ratchet can only rotate in one direction under the action of the pawl, and cannot rotate to the outside of the sliding groove, so that the driving block is not easily separated from the sliding groove by factors such as wall vibration, thereby improving the stability of the support frame fixation; when the support frame is aged or damaged after long-term use, the staff can move the control rod, and the control rod can drive the pawl to move, so that the pawl and the ratchet are separated, and then the driving rod is rotated in the opposite direction, so that the driving rod drives the driving block to separate from the sliding groove, and then the connecting block can move downward under the action of gravity to separate from the connecting groove, thereby releasing the fixation of the support frame;

[0041] 6. The interference fit between the driving block and the side wall of the sliding groove makes the driving block clamped into the sliding groove, so that the support frame is not easy to shake in the direction perpendicular to the wall surface, thereby firmly fixing the support frame; on the other hand, the driving block is not easy to move in the lateral direction of the wall surface, so that the support frame is not easy to shake in the lateral direction, thereby improving the stability of the support frame fixation;

[0042] 7. The installation position of the support plate and the support frame can be fine-tuned by longitudinally adjusting the fixing assembly, so that the construction workers do not need to re-drill the wall after the hole position is deviated, thereby improving the fault tolerance and construction efficiency of the construction workers during construction, and it is not easy to cause secondary damage to the wall.

[0050] The following is combined with Figure 1-6 This application is described in further detail.

[0051] The present application embodiment discloses a heat preservation structure. Figure 1 and Figure 2 The insulation structure includes a plurality of support frames 2 for being arranged outside the wall 1, and an insulation board 3 made of polyurethane material is arranged inside the support frame 2. Adhesive layers 4 made of a mixture of polymer adhesive mortar and interface agent are laid on both sides of the insulation board 3. A protective layer 5 is laid outside the adhesive layer 4, and the protective layer 5 is used to protect the internal adhesive layer 4, the support frame 2 and the insulation board 3. The protective layer 5 includes a fiber mesh 51, a waterproof layer 52, and a decorative surface layer 53 laid on the outside of the adhesive layer 4 in sequence, wherein the waterproof layer 52 is made of flexible water-resistant putty material, and the fiber mesh 51 is used to increase the toughness of the protective layer 5, so that the protective layer 5 is not prone to local cracking. The decorative surface layer 53 is used to improve the aesthetics of the protective layer 5 and to make the internal waterproof layer 52 and the fiber mesh 51 not easily damaged. An adjustment and fixing connection mechanism 6 is arranged between the support frame 2 and the wall 1, and the adjustment and fixing connection mechanism 6 is used to fix and adjust the position of the support frame 2, and at the same time connect the two adjacent support frames 2 above and below.

[0052] When the construction workers renovate the exterior walls of houses in old communities, they first clean the exterior wall surface, then apply the adhesive layer 4 on the exterior wall surface, then abut the support frame 2 against the exterior wall surface, and adjust the installation position of the support frame 2 by adjusting the fixed connection mechanism 6, so that adjacent support frames 2 are aligned horizontally and vertically along the vertical plane of the wall 1, and then fix the position of the support frame 2 by adjusting the fixed connection mechanism 6, and fill the interior of the support frame 2 with the insulation board 3 so that the insulation board 3 abuts against the adhesive layer 4, and then the construction workers repeat the above process to complete the installation of multiple support frames 2 and insulation boards 3, and connect the upper and lower adjacent support frames 2 by adjusting the fixed connection mechanism 6 to form a whole, and finally the construction workers lay the adhesive layer 4 and the protective layer 5 on the outside of the support frame 2 and the insulation board 3 in turn to complete the renovation of the exterior wall of the old house.

[0053] Reference Figure 3 and Figure 4 The adjustment and fixing connection mechanism 6 includes a support plate 61 that abuts against the outer side of the wall 1 along the wall surface in the horizontal direction. A plurality of support rods 62 are fixedly arranged at intervals on the side of the support plate 61 away from the wall 1. A support hole 21 adapted to the support rod 62 is provided on the support frame 2. The support hole 21 is a horizontal waist-shaped hole that is provided in the horizontal direction and adapted to the support rod 62. The support rod 62 can be located and moved in the horizontal waist-shaped hole. A longitudinal adjustment and fixing component 63 is provided between the support plate 61 and the wall 1. The longitudinal adjustment and fixing component 63 is used to longitudinally adjust and fix the position of the support frame 2 along the plane of the wall 1. A transverse adjustment and fixing component 64 is provided between the support rod 62 and the support frame 2. The transverse adjustment and fixing component 64 is used to transversely adjust and fix the position of the support frame 2 along the plane of the wall 1, and to connect and fix two adjacent support frames 2 above and below.

[0054] Reference Figure 3 and Figure 4 The longitudinal adjustment fixing assembly 63 includes a stud expansion bolt 631 disposed between the support plate 61 and the wall 1, a nut 632 is disposed at one end of the stud expansion bolt 631, a longitudinal waist-shaped hole 611 disposed along the longitudinal direction of the wall 1 is provided on the support plate 61, one end of the stud expansion bolt 631 passes through the longitudinal waist-shaped hole 611 and is threadedly connected with the nut 632, and the nut 632 is pressed to the side of the support plate 61 away from the wall 1. The longitudinal adjustment fixing assembly 63 can fine-tune the installation position of the support plate 61 and the support frame, so that the construction personnel do not need to re-drill the wall 1 after the hole position is deviated, thereby improving the fault tolerance rate and construction efficiency of the construction personnel during construction, and it is not easy to cause secondary damage to the wall 1.

[0055] Reference Figure 4 and Figure 5The lateral adjustment fixing assembly 64 includes a driving rod 641 rotatably connected to the support rod 62, a driving block 642 is fixedly sleeved on the driving rod 641, the cross sections of the support rod 62 and the driving block 642 are both elliptical, a driving groove 621 is provided on the side wall of the support rod 62, and the driving block 642 can be rotated to the outside of the driving groove 621. A connecting block 643 is slidably connected to the top of the support frame 2 in the vertical direction, a sliding groove 22 is provided on the top of the support frame 2, and the support hole 21 is connected to the sliding groove 22, and a connecting groove 23 adapted to the connecting block 643 is provided at the bottom of the support frame 2, and the connecting block 643 can be located in the sliding groove 22 and slide, and one end can be plugged into the connecting groove 23. When the elliptical major axis of the driving block 642 coincides with the elliptical minor axis of the support rod 62, the driving block 642 drives the connecting block 643 to be inserted into the connecting groove 23 at the bottom of the upper adjacent support frame 2, and at the same time the driving block 642 enters the sliding groove 22, and the driving block 642 and the side wall of the sliding groove 22 have an interference fit, and the interference fit is used to clamp the driving block 642 into the sliding groove 22, so that the support frame 2 is not easy to shake along the direction perpendicular to the wall surface of the wall 1 and along the horizontal direction of the wall surface of the wall 1, thereby firmly fixing the support frame 2.

[0056] Reference Figure 5 and Figure 6 A limit component 644 is provided between the driving rod 641 and the support rod 62. The driving rod 641 cooperates with the limit component 644 to control the rotation angle of the driving block 642, so that the construction personnel can accurately control the position of the elliptical major axis of the driving block 642, thereby facilitating the fixation of the support frame 2 and the connection of the upper and lower support frames 2. An anti-loosening and anti-vibration component 645 is also provided between the driving rod 641 and the support rod 62. The anti-loosening and anti-vibration component 645 is used to lock the driving rod 641, so that after the driving rod 641 drives the driving block 642 to rotate into the sliding groove 22, the driving block 642 is locked, so that the driving block 642 is not easily separated from the sliding groove 22 by factors such as the vibration of the wall 1, thereby improving the stability of the thermal insulation structure.

[0057] Reference Figure 4 and Figure 5The limiting component 644 includes two first limiting blocks 6441 fixedly arranged on the side of the support rod 62 away from the wall 1, and a second limiting block 6442 is fixedly arranged on the outer wall of the driving rod 641, and the second limiting block 6442 is located between the two first limiting blocks 6441. When the construction personnel rotate the driving rod 641, after the first limiting block 6441 abuts against one of the second limiting blocks 6442, it means that the elliptical minor axis of the driving block 642 coincides with the elliptical minor axis of the support rod 62, and at this time, the support rod 62 and the support frame 2 are in an unlocked state. When the second limiting block 6442 rotates to abut against the other first limiting block 6441, it means that the elliptical major axis of the driving block 642 coincides with the elliptical minor axis of the support rod 62, and at this time, the support rod 62 and the support frame 2 are in a locked state. The construction personnel can more conveniently and quickly determine whether the support frame 2 is in a fixed state by making the first limit block 6441 abut against the two second limit blocks 6442 respectively.

[0058] Reference Figure 4 and Figure 6 The anti-loosening and anti-vibration component 645 includes a ratchet 6451 fixedly sleeved on the outside of the driving rod 641, and a pawl 6452 is rotatably connected in the support rod 62, and the ratchet 6451 and the pawl 6452 are meshed with each other. A spring 6453 is arranged between the pawl 6452 and the ratchet 6451, and the spring 6453 always gives the pawl 6452 a force to approach the ratchet 6451. A control rod 6454 is fixedly arranged at one end of the ratchet 6451 away from its rotation axis, and one end of the control rod 6454 passes through the support rod 62 and is located on the outside of the support rod 62. When the staff rotates the driving rod 641 so that the driving rod 641 drives the elliptical major axis of the driving block 642 to rotate into the sliding groove 22, the limiting component 644 prevents the driving rod 641 from continuing to rotate. At this time, the ratchet 6451 can only rotate in one direction under the action of the pawl 6452, and cannot rotate to the outside of the sliding groove 22, so that the driving block 642 is not easily disengaged from the sliding groove 22 due to factors such as the vibration of the wall 1, thereby improving the stability of the fixation of the support frame 2; when the support frame 2 is aged or damaged after long-term use, the staff can move the control rod 6454, and the control rod 6454 can drive the pawl 6452 to move, so that the pawl 6452 and the ratchet 6451 are separated, and then the driving rod 641 is rotated in the opposite direction, so that the driving rod 641 drives the driving block 642 to disengage from the sliding groove 22, and then the connecting block 643 can move downward under the action of gravity to disengage from the connecting groove 23, thereby releasing the fixation of the support frame 2.

[0059] When the construction personnel adjust and fix the support frame 2 by adjusting the fixing connection mechanism 6, first, the support plate 61 is abutted against one side of the wall 1, and then the hole position is marked on the wall according to the installation requirements, and the wall 1 is punched, and then one end of the double-headed expansion bolt 631 is installed in the hole opened on the wall 1, and the other end of the double-headed expansion bolt 631 is inserted into the longitudinal waist-shaped hole 611 on the support plate 61, and the nut 632 is tightened to achieve the fixation of the support plate 61; if the support plate 61 is longitudinally deflected, the construction personnel can loosen the nut 632, adjust the installation position of the support plate 61 up and down, and level the support plate 61; then the construction personnel insert the support rod 62 into the support hole 21 on the support frame 2, and make fine adjustments along the horizontal direction of the wall 1 plane, adjust the relative position of the support rod 62 and the support frame 2, and achieve the horizontal adjustment of the support frame 2, so that multiple support frames 2 are aligned and fixed along the horizontal direction of the wall 1 plane.

[0060] Then, the driving rod 641 is rotated, and the driving rod 641 drives the driving block 642 to rotate, so that one side of the elliptical major axis of the driving block 642 rotates to the outside of the driving groove 621, and at the same time, the driving block 642 enters the sliding groove 22 on the one hand, and on the other hand, the driving block 642 pushes out the connecting block 643, so that the connecting block 643 is inserted upward into the connecting groove 23 at the bottom of the upper adjacent supporting frame 2, so as to realize the connection between the upper and lower adjacent supporting frames 2. Among them, through the mutual cooperation of the support plate 61, the support rod 62, the longitudinal adjustment fixing assembly 63 and the transverse adjustment fixing assembly 64, when the construction personnel install and fix the supporting frame 2, they can adjust the position of the supporting frame 2 along the transverse and longitudinal direction of the wall 1 plane, realize the rapid fixed installation of the supporting frame 2, and also reduce the installation difficulty and installation accuracy of the supporting frame 2, improve the fault tolerance rate of the construction personnel during construction, and reduce the construction cost.

[0061] The present application also provides a construction method of a thermal insulation structure, which is applicable to the thermal insulation structure described above, and the construction steps are as follows:

[0062] S1. Clean the exterior wall;

[0063] S2, coating an adhesive layer 4 on the exterior wall surface;

[0064] S3, the support frame 2 is abutted against the surface of the outer wall, and the installation position of the support frame 2 is adjusted by the support plate 61, the support rod 62, the longitudinal adjustment fixing assembly 63 and the transverse adjustment fixing assembly 64, so that adjacent support frames 2 are aligned and fixed in the transverse and longitudinal directions along the vertical plane of the wall 1;

[0065] S4, filling the insulation board 3 into the support frame 2, so that the insulation board 3 is bonded to the adhesive layer 4;

[0066] S5, repeat the above process to complete the installation of multiple support frames 2 and insulation boards 3, and connect two upper and lower adjacent support frames 2 by adjusting the fixed connection mechanism 6 to form a whole;

[0067] S6. Lay the adhesive layer 4 and the protective layer 5 on the outer sides of the support frame 2 and the insulation board 3 in sequence.

[0068] The implementation principle of an insulation structure and a construction method thereof in an embodiment of the present application is as follows: when the construction workers renovate the exterior walls of houses in old communities, they first clean the exterior wall surface, then apply an adhesive layer 4 on the exterior wall surface, then abut the support frame 2 against the exterior wall surface, and adjust the installation position of the support frame 2 by adjusting the fixed connection mechanism 6 so that adjacent support frames 2 are aligned in the horizontal and vertical directions along the vertical plane of the wall 1, then fix the position of the support frame 2 by adjusting the fixed connection mechanism 6, and fill the interior of the support frame 2 with an insulation board 3 so that the insulation board 3 abuts against the adhesive layer 4, then the construction workers repeat the above process to complete the installation of multiple support frames 2 and insulation boards 3, and adjust the fixed connection mechanism 6 so that the upper and lower adjacent support frames The support frame 2 and the insulation board 3 are connected to form a whole. Finally, the construction workers lay the adhesive layer 4 and the protective layer 5 on the outside of the support frame 2 and the insulation board 3 in turn, and the renovation of the exterior wall of the old house can be completed. Among them, the use of the above-mentioned insulation structure to renovate the exterior wall of the old community house not only shortens the construction period, saves the renovation cost, and significantly improves the insulation effect of the wall 1. The overall load-bearing capacity of the insulation structure depends on the connection between the support frame 2 and the wall 1, so that the insulation board 3 is not easy to bear the longitudinal shear force of the support frame 2 and each structural layer under the gravity, so that the insulation board 3 is not easy to crack locally, and the service life of the insulation board 3 is improved. At the same time, the fixed connection mechanism 6 can be adjusted to adjust the installation position of the insulation board 3 and the support frame 2, thereby improving the construction efficiency and installation convenience of the construction workers.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
