Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to a safe and environmentally friendly construction process for membrane bag insulation board external insulation projects. Background Technology

[0002] Membrane bag insulation board is a building material that is a board installed on walls or ceilings to improve the thermal insulation and waterproofing effects of the interior. When installing membrane bag insulation board, it needs to be combined with external insulation projects to ensure that the membrane bag insulation board is effective for a long time and is not easily damaged.

[0003] Currently, when using membrane insulation panels for external insulation projects, holes need to be drilled on the surface of the membrane insulation panels to install curtain wall cladding panels. This damages the overall structure of the membrane insulation panels, increasing the number of steps in the external insulation process and raising construction costs. Furthermore, drilling holes can cause the membrane insulation panels to crack, compromising their integrity and rendering them ineffective at waterproofing. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a safe and environmentally friendly construction process for external insulation projects using membrane bag insulation boards. By constructing the exterior of the membrane bag insulation board, the wall insulation effect is achieved. Furthermore, a layer of waterproof paint applied to the surface of the membrane bag insulation board provides a waterproof effect. Since the corners of the four insulation board brackets form limiting holes, they can be used to fix the external decorative mechanism of the membrane bag insulation board without the need for additional drilling on the membrane bag insulation board, ensuring its integrity and reducing the construction steps. Through the keel frame and limiting holes, the main body of the decorative panel and the membrane bag insulation board can be quickly installed and disassembled, reducing the maintenance difficulty and cost of the membrane bag insulation board.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The safe and environmentally friendly construction process for membrane bag insulation board external insulation projects includes the following steps:

[0007] S1. Base surface treatment: Hang the baseline and control line on the surface of the wall, set the system expansion joint, then drill holes according to the baseline and control line, pre-attach the wrapping mesh, then install the insulation board bracket through the drilled holes, and prepare the adhesive.

[0008] S2. Installation of membrane bag insulation board: Apply adhesive to the surface of the insulation board bracket and the wall, embed the membrane bag insulation board into the insulation board bracket, fill the gap with adhesive powder polystyrene particle mortar, prepare the plastering mortar, and apply the first coat of plastering mortar to the surface of the membrane bag insulation board.

[0009] S3. Surface treatment of membrane bag insulation board: cover and wrap the mesh, press and lay the reinforcing mesh at the opening and the first layer of alkali-resistant fiberglass mesh, drill holes at the corners of the insulation board bracket, install anchor bolts, then apply the second coat of plastering mortar, and apply a layer of waterproof paint to the surface of the membrane bag insulation board.

[0010] S4. External treatment of membrane bag insulation board: Lay the second layer of alkali-resistant fiberglass mesh, apply the third coat of plastering mortar, and then decorate the exterior of the membrane bag insulation board. The corners of the four insulation board brackets are fitted together to form limiting holes for fixing the external decorative mechanism of the membrane bag insulation board. Finally, the project is inspected.

[0011] The external finishing treatment of membrane bag insulation boards includes mortar construction, putty powder construction, flexible decorative panel construction, or keel frame construction;

[0012] The keel frame construction involves installing the keel frame and heat insulation pads on the outside of the membrane bag insulation board. The keel frame is installed by connecting the installation feet through telescopic rods and telescopic sleeves. The installation feet cooperate with the limiting holes formed by the corners of the insulation board bracket to fix the keel frame in place. The decorative panel body is then installed on the surface of the keel frame.

[0013] As a further aspect of the present invention: the mortar construction includes:

[0014] Apply a putty coating to the outside of the membrane bag insulation board, then apply finishing mortar to the putty coating and clean the surface.

[0015] As a further aspect of the present invention: the putty powder application includes:

[0016] Use flexible exterior wall putty powder to smooth the outside of the membrane bag insulation board, apply the paint layer formed by the putty powder, and clean the surface layer.

[0017] As a further aspect of the present invention: the construction of the flexible decorative panel includes:

[0018] Apply flexible facing brick adhesive to the outside of the membrane bag insulation board, install the flexible facing bricks and grout them, and clean the surface.

[0019] As a further aspect of the present invention: the telescopic rod is inserted into one end of the telescopic sleeve, and the telescopic sleeve adjusts the height of the keel frame through the telescopic rod.

[0020] As a further aspect of the present invention: the insulation board bracket includes a first pad and a second pad, and a telescopic plate is provided between the first pad and the second pad. The distance between the first pad and the second pad is adjusted by the telescopic plate to control the area of ​​the insulation board bracket.

[0021] As a further aspect of the present invention: an actuating disc is installed inside the telescopic sleeve, a lever is fixedly connected to one side of the actuating disc, a roller is mounted on the end of the lever away from the actuating disc via a rotating shaft, the end of the lever away from the actuating disc extends beyond the inner wall surface of the telescopic sleeve, a first gear is engaged on the side of the actuating disc, a second gear is connected to the first gear via a toothed belt, an anti-disengagement locking tongue is engaged on the bottom surface of the second gear, a sealing piston is provided at the top of the telescopic rod, and the anti-disengagement locking tongue cooperates with the sealing piston to fix the position of the telescopic rod.

[0022] As a further aspect of the present invention: a tension spring is rotatably connected to the middle position of the side of the lever, and the end of the tension spring away from the lever is fixed to the position of the telescopic sleeve by a rotating shaft, and is on the same horizontal plane as the center of the lever disc.

[0023] As a further aspect of the present invention: a grid frame is fixedly connected to the inner side of the keel frame, and a rotating disk is mounted on the top surface of the grid frame via a bearing. The rotating disk is used for quick assembly and disassembly of the decorative panel body.

[0024] The beneficial effects of this invention are:

[0025] 1. In this invention, the insulation effect of the wall is achieved through the construction of the exterior of the membrane bag insulation board. Furthermore, the waterproof paint applied to the surface of the membrane bag insulation board provides a waterproof effect. Since the corners of the four insulation board brackets cooperate to form limiting holes, the external decorative mechanism of the membrane bag insulation board can be fixed without the need for additional drilling on the membrane bag insulation board, ensuring the integrity of the membrane bag insulation board and reducing the construction process. Through the set keel frame and limiting holes, the main body of the decorative panel and the membrane bag insulation board can be quickly installed and disassembled, reducing the maintenance difficulty and cost of the membrane bag insulation board.

[0026] 2. In this invention, the rotating disc, driven by the keel frame, drives a rotating gear. This gear, via a rack, drives a moving rod, which in turn moves a limiting bracket. This causes the limiting bracket to disengage from the limiting groove and from the anti-disengagement hole on the back of the decorative panel body, thus achieving rapid disassembly from the decorative panel body. During installation, the rotating disc is first rotated, then the fixing block detached from the back of the decorative panel body is aligned with the limiting groove and inserted. The rotating disc is then released, and the limiting bracket automatically inserts into the anti-disengagement hole, achieving automatic installation and fixation of the detached decorative panel body, thus enabling rapid installation.

[0027] 3. In this invention, through the telescopic sleeve and telescopic rod, when the keel frame is installed, external air can enter the inner cavity of the telescopic sleeve through the small round hole and the air channel, ensuring that the telescopic rod is not subject to resistance. When the telescopic rod slides and the buckle at the top of the telescopic rod exceeds the lever, the anti-detachment locking tongue will be at the bottom of the buckle under the action of the spring force, thereby restricting the position of the telescopic rod and preventing it from slipping out of the inner cavity of the telescopic sleeve. The compression spring also acts on the inner end of the telescopic rod to ensure its stability. During disassembly, simply move the telescopic rod slightly inward, and it will push the lever. The lever drives the first gear through the actuating disc, the first gear drives the second gear, and the second gear drives the anti-detachment locking tongue, causing the anti-detachment locking tongue to overcome the spring force and move inward, disengaging from the buckle of the telescopic rod. This ensures that the telescopic rod can move to the outer end of the telescopic sleeve, facilitating the installation and disassembly of the keel frame.

[0028] 4. In this invention, when the anti-loosening locking tongue is released, the telescopic rod will slide in the inner cavity of the telescopic sleeve, squeezing the air in the inner cavity of the telescopic sleeve. The venting block will move towards the outer end of the venting groove and seal the air delivery groove. At this time, the air in the inner cavity of the telescopic sleeve can only be discharged through the small round hole. Since the amount of air discharged through the small round hole is small, the sliding speed of the telescopic rod in the inner cavity of the telescopic sleeve can be controlled to prevent the telescopic rod from causing the keel frame to fall quickly. On the one hand, this ensures the safety of the keel frame and the main body of the decorative panel, and on the other hand, it prevents the keel frame from falling too fast and injuring the workers, thus improving safety.

[0042] 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.

[0043] like Figures 1-11 As shown, the safe and environmentally friendly construction process for membrane bag insulation board external insulation projects includes the following steps:

[0044] S1. Base surface treatment: Hang the baseline and control line on the surface of the wall, set the system expansion joint, then drill holes according to the baseline and control line, pre-attach the wrapping mesh, and then install the insulation board bracket 1 through the drilled holes and prepare the adhesive.

[0045] S2. Installation of membrane bag insulation board: Apply adhesive to the surface of insulation board bracket 1 and the wall, embed the membrane bag insulation board into the insulation board bracket 1, fill the gap with adhesive powder polystyrene particle mortar, prepare the plastering mortar, and apply the first coat of plastering mortar to the surface of the membrane bag insulation board.

[0046] S3. Surface treatment of membrane bag insulation board: cover and turn the mesh, press and lay the reinforcing mesh at the opening and the first layer of alkali-resistant fiberglass mesh, drill holes at the corners of the insulation board bracket 1, install anchor bolts, then apply the second coat of plastering mortar, and apply a layer of waterproof paint to the surface of the membrane bag insulation board.

[0047] S4. External treatment of membrane bag insulation board: Lay the second layer of alkali-resistant fiberglass mesh, apply the third layer of plastering mortar, and then decorate the exterior of the membrane bag insulation board. The corners of the four insulation board brackets 1 are fitted together to form limiting holes for fixing the external decoration mechanism of the membrane bag insulation board. Finally, the project is inspected.

[0048] The external finishing treatment of the membrane bag insulation board includes mortar construction, putty powder construction, flexible decorative panel construction, or keel frame construction.

[0049] The keel frame 3 is installed on the outside of the membrane bag insulation board body 2, along with the heat insulation pad. The keel frame 3 is connected to the mounting feet 7 via the telescopic rod 5 and telescopic sleeve 6. The mounting feet 7 are matched with the limiting holes formed by the corners of the insulation board bracket 1 to fix the keel frame 3 in place. The decorative panel body 4 is then installed on the surface of the keel frame 3.

[0050] Mortar construction includes:

[0051] Apply a putty coating to the outside of the membrane bag insulation board, then apply finishing mortar to the putty coating and clean the surface.

[0052] Putty powder application includes:

[0053] Use flexible exterior wall putty powder to smooth the outside of the membrane bag insulation board, apply the paint layer formed by the putty powder, and clean the surface layer.

[0054] Flexible decorative panel installation includes:

[0055] Apply flexible facing brick adhesive to the outside of the membrane bag insulation board, install the flexible facing bricks and grout them, and clean the surface.

[0056] The telescopic rod 5 is inserted into one end of the telescopic sleeve 6, and the telescopic sleeve 6 adjusts the height of the keel frame 3 through the telescopic rod 5.

[0057] The insulation board bracket 1 includes a bracket body 11, expansion bolts 12 at the four corners of the bracket body 11, a first pad 13 and a second pad 14, and a telescopic plate 15 between the first pad 13 and the second pad 14. The distance between the first pad 13 and the second pad 14 is adjusted by the telescopic plate 15 to control the area of ​​the insulation board bracket 1.

[0058] The telescopic sleeve 6 has an actuating disc 65 installed inside. A lever 66 is fixedly connected to one side of the actuating disc 65. A roller is mounted on the end of the lever 66 away from the actuating disc 65 via a rotating shaft. The end of the lever 66 away from the actuating disc 65 extends beyond the inner wall surface of the telescopic sleeve 6. A first gear 67 is engaged on the side of the actuating disc 65. A second gear 68 is connected to the first gear 67 via a toothed belt. An anti-disengagement locking tongue 69 is engaged on the bottom surface of the second gear 68. A sealing piston is provided at the top of the telescopic rod 5. The anti-disengagement locking tongue 69 cooperates with the sealing piston. The piston fixes the position of the telescopic rod 5. A tension spring is rotatably connected to the middle of the side of the lever 66. The end of the tension spring away from the lever 66 is fixed to the position of the telescopic sleeve 6 through a rotating shaft and is on the same horizontal plane as the center of the lever 65. A venting groove 61 is provided at the bottom of the telescopic sleeve 6. A venting block 62 is provided inside the venting groove 61. A small round hole 63 passes through the venting block 62. An air delivery groove 64 is provided on the inner wall of the venting groove 61. The venting groove 61 communicates with the inner cavity of the telescopic sleeve 6 through the air delivery groove 64.

[0059] When the anti-loosening latch 69 is released, the telescopic rod 5 will slide in the inner cavity of the telescopic sleeve 6, which will squeeze the air in the inner cavity of the telescopic sleeve 6. The vent block 62 will move towards the outer end of the vent groove 61 and seal the air supply groove 64. At this time, the air in the inner cavity of the telescopic sleeve 6 can only be discharged through the small round hole 63. Since the amount of air discharged through the small round hole 63 is small, the sliding speed of the telescopic rod 5 in the inner cavity of the telescopic sleeve 6 can be controlled to prevent the telescopic rod 5 from causing the keel frame 3 to fall quickly. On the one hand, this ensures the safety of the keel frame 3 and the decorative panel body 4, and on the other hand, it prevents the keel frame 3 from falling too fast and injuring the staff, thus improving safety.

[0060] When installing the keel frame 3, the telescopic rod 5 can be pressed into the inner cavity of the telescopic sleeve 6. At this time, the telescopic rod 5 will draw in air through the vent groove 61. The vent block 62 will move closer to the inner end of the vent groove 61. At this time, external air can enter the inner cavity of the telescopic sleeve 6 through the small round hole 63 and the air supply groove 64, ensuring that the telescopic rod 5 is not subject to resistance. When the telescopic rod 5 slides and ensures that the inverted buckle at the top of the telescopic rod 5 exceeds the lever 66, the anti-loosening locking tongue 69 will be at the bottom of the inverted buckle under the action of the spring force, thereby restricting the position of the telescopic rod 5 and preventing the telescopic rod 5 from sliding out of the telescopic sleeve 6. When the inner cavity of sleeve 6 slips, the compression spring 8 will also act on the inner end of the telescopic rod 5 to ensure the stability of the telescopic rod 5. During disassembly, simply move the telescopic rod 5 slightly inward, and the telescopic rod 5 will push the lever 66. The lever 66 drives the first gear 67 through the lever disc 65. The first gear 67 drives the second gear 68, and the second gear 68 drives the anti-loosening locking tongue 69, causing the anti-loosening locking tongue 69 to overcome the spring force and move inward, disengaging from the inverted buckle of the telescopic rod 5. This ensures that the telescopic rod 5 can move to the outer end of the telescopic sleeve 6, facilitating the installation and disassembly of the keel frame 3.

[0061] A grid frame 32 is fixedly connected to the inner side of the keel frame 3. A rotating disk 33 is mounted on the top surface of the grid frame 32 via a bearing. The rotating disk 33 is used for quick assembly and disassembly of the decorative panel body 4. A moving rod 36 is provided on the inner side of the grid frame 32. A limiting groove 31 is provided at the edge of the keel frame 3 near the moving rod 36. A rack 35 is fixedly connected to the end of the moving rod 36 away from the limiting groove 31. A rotating gear 34 meshes with the inner side of the rack 35. A rotating disk is fixedly connected to one side of the rotating gear 34. 33, the rotating disk 33 is installed in the middle of the bottom surface of the grid frame 32 through the bearing. A spring is also provided between the grid frame 32 and the moving rod 36 to support the moving rod 36 and ensure that the limiting frame 37 connected to the end of the moving rod 36 near the limiting groove 31 can be inserted into the limiting groove 31. A fixing block that fits into the limiting groove 31 is fixedly connected to the back of the decorative panel body 4 near the limiting groove 31. The fixing block has an anti-disengagement hole that fits into the limiting frame 37 at the position near the limiting frame 37.

[0062] During operation, the rotating disk 33 is first rotated. The rotating disk 33 drives the rack 35 via the rotating gear 34. The rack 35 then drives the moving rod 36. The moving rod 36 overcomes the elastic force of the spring between itself and the moving rod 36, causing the limiting frame 37 to disengage from the limiting groove 31. Simultaneously, the limiting frame 37 disengages from the limiting groove 31 and also from the anti-disengagement hole on the fixing block on the back of the decorative panel body 4, ensuring that the decorative panel body 4 is not fixed by the limiting frame 37. Since the limiting frame 37 moves synchronously, all the fixing blocks on the back of the decorative panel body 4 will be released simultaneously, ensuring that the decorative panel body 4 can be removed from the keel frame in one step. The main body of the decorative panel 4 can be disassembled for maintenance and replacement, reducing the difficulty of maintenance and replacement. When the main body of the decorative panel 4 needs to be installed, the end of the limiting bracket 37 can be set as an inclined surface. This allows the fixing block on the back of the decorative panel 4 to be pressed into the limiting groove 31. The inclined surface will automatically overcome the spring force due to the squeezing of the fixing block. When the fixing block is fully inserted into the limiting groove 31, the moving rod 36 will drive the limiting bracket 37 to automatically embed into the limiting groove 31 under the action of the spring force, and at the same time insert into the anti-dislodgement hole on the fixing block, thus realizing the automatic fixing of the decorative panel 4 and reducing the installation difficulty of the decorative panel 4.

[0063] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
