Description

Technical Field

[0001] This application relates to the field of building insulation, and in particular to integrated insulation panels and their construction methods. Background Technology

[0002] In the construction industry, the application of integrated insulation panels is of great significance for improving the energy efficiency of buildings.

[0003] When installing integrated thermal insulation panels on building exterior walls, the common method is to pre-embed expansion sleeves in the exterior wall, then use anchor rods to pass through the insulation panel and screw them into the expansion sleeves. This installation method is currently a common way to fix integrated thermal insulation panels in the construction industry, and it can ensure the stability of the insulation panels to a certain extent. Many construction projects prioritize this installation method when carrying out exterior wall insulation construction because it is relatively simple, low-cost, and has high construction efficiency.

[0004] However, the existing installation method has obvious drawbacks. Since anchor rods are generally made of metal, which has good thermal conductivity, using anchor rods to install integrated insulation panels on the exterior walls of buildings will create thermal bridges, thereby reducing the thermal insulation performance of the integrated insulation panels. Summary of the Invention

[0005] In order to improve the thermal insulation performance of integrated insulation panels, this application provides integrated insulation panels and their construction methods.

[0006] The integrated thermal insulation panel and its construction method provided in this application adopt the following technical solution: An integrated thermal insulation panel includes an insulation substrate and a decorative layer fixedly installed on one side of the insulation substrate. The insulation substrate has multiple anchoring holes and multiple pressure grooves on the side of the insulation substrate near the decorative layer. The pressure grooves are coaxially arranged with the anchoring holes, and the diameter of the pressure grooves is larger than that of the anchoring holes. An anchor rods are slidably inserted through the anchoring holes. A pressure plate is fixedly installed at one end of the anchor rod, and an expansion sleeve is provided at the other end of the anchor rod. The expansion sleeve is pre-embedded in the exterior wall of the building, and the anchor rods are threaded through the expansion sleeves. A storage bag is fixedly installed on the side of the pressure plate away from the anchor rods. The storage bag contains polyurethane foam, which is used to foam and form insulation blocks.

[0007] By adopting the above technical solution, the integrated insulation panel consists of an insulation substrate and a decorative layer. The insulation substrate has anchoring holes and grooves. Anchor rods pass through the anchoring holes and are threadedly connected to expansion sleeves pre-embedded in the building's exterior wall. The pressure plate presses against the inner wall of the groove, which can securely install the integrated insulation panel on the building's exterior wall. After puncturing the storage bag, polyurethane foam foams inside the groove to form an insulation block. The insulation block is located on the side of the pressure plate away from the anchor rod, which can effectively reduce thermal bridges caused by heat conduction from the anchor rod and improve the insulation performance of the integrated insulation panel.

[0008] Optionally, the insulation substrate has a placement groove on the side near the decorative layer. The placement groove is coaxial with the pressure groove, and the diameter of the placement groove is larger than the diameter of the pressure groove. A baffle plate is provided inside the placement groove. A connecting rod is installed on the side of the pressure plate away from the anchor rod. The connection between the connecting rod and the pressure plate is easily separable. The baffle plate has an inlet and outlet hole for the connecting rod to slide through. A limit block is fixedly installed on the end of the connecting rod away from the pressure plate. The insulation block is located between the baffle plate and the pressure plate.

[0009] By adopting the above technical solution, the baffle can restrict the insulation block. When the anchor rod is passed through the anchor hole and screwed into the expansion sleeve, the baffle will move the insulation block with the pressure plate and enter the pressure groove, reducing the need for workers to manually insert the insulation block into the pressure groove.

[0010] Optionally, the baffle is fixedly connected to the storage bag, and the baffle and the pressure plate are spaced apart from each other to tear the storage bag.

[0011] By adopting the above technical solution, after the shield moves away from the pressure plate and tears the storage bag, the polyurethane foam inside the storage bag foams to form an insulation block, which can fill the gaps around the anchoring holes, improve the insulation performance of the integrated insulation panel, and this method can form an insulation block on-site during the installation process, which is convenient for operation.

[0012] Optionally, multiple drive rods are installed on the end of the connecting rod near the pressure plate. A first drive groove is provided on the side of the pressure plate near the baffle for the connecting rod to pass through in a damping manner. A second drive groove is also provided on the side of the pressure plate near the baffle for the drive rod to pass through in a damping manner.

[0013] By adopting the above technical solution, after the anchor rod is screwed into the expansion sleeve, the connecting rod damping passes through the first drive groove of the pressure plate, and the drive rod damping passes through the second drive groove of the pressure plate, which makes it easy to pull out the connecting rod.

[0014] Optionally, the end of the drive rod away from the connecting rod is tapered for puncturing the storage bag.

[0015] By adopting the above technical solution, when the connecting rod is removed, the drive rod will move with the connecting rod, using its conical end to puncture the storage bag, thereby allowing the polyurethane foam to foam and form an insulation block, which is convenient to operate.

[0016] Optionally, a first mounting block is fixedly installed at one end of the connecting rod near the pressure plate. The first mounting block is provided with a second mounting block. The second mounting block has a mounting groove for the first mounting block to be inserted into the damping mechanism. The cross-sectional area of ​​the second mounting block gradually increases from one side near the connecting rod to the other side. The second mounting block is used for damping insertion into the inlet and outlet. The drive rod is fixedly installed on the periphery of the second mounting block.

[0017] By adopting the above technical solution, the damping plug-in connection between the first mounting block and the second mounting block facilitates the installation and disassembly of the connecting rod and the second mounting block; the cross-sectional area of ​​the second mounting block gradually increases and the damping plug-in is inserted at the inlet and outlet, which can stably position it at the inlet and outlet for sealing.

[0018] Optionally, the pressure plate has multiple leakage holes, which are connected to the anchoring holes.

[0019] By adopting the above technical solution, polyurethane foam can enter the anchoring hole from the leakage hole, and fill the gap after foaming in the anchoring hole. This can not only improve the connection strength between the insulation substrate and the anchor rod, but also play a role in heat preservation.

[0020] Optionally, a slot is provided on the periphery of the thermal insulation substrate, the slot being used for two thermal insulation substrates to be snapped together, and a first sealing sheet is fixedly installed on the inner wall of the slot.

[0021] By adopting the above technical solution, the slots opened on the periphery of the insulation substrate can allow two insulation substrates to be interlocked, which is convenient for installation and splicing; the first sealing piece fixed to the inner wall of the slot can enhance the sealing of the splicing of the integrated insulation panel.

[0022] Optionally, the first sealing sheet is provided with a second sealing sheet, the periphery of the first sealing sheet and the second sealing sheet are fixedly connected to each other, and a talc powder layer is filled between the first sealing sheet and the second sealing sheet.

[0023] By adopting the above technical solution, when two thermal insulation substrates are spliced ​​together, the talc powder layer can cause the first sealing sheet and the second sealing sheet to slide relative to each other, which facilitates the splicing of the two thermal insulation substrates.

[0024] The construction method of integrated thermal insulation panels includes the following steps: Modeling based on measured data of the building's exterior wall; using laser cutting technology to cut the insulation substrate into irregular shapes during the panel production stage, and pre-fabricating anchor holes and grooves; repairing defects in the building's exterior wall using localized point chiseling and polymer cement mortar; cleaning surface dust and oil stains with high-pressure air; positioning the installation location of the integrated thermal insulation panel on the building's exterior wall and pre-embedding expansion sleeves; applying an interface agent to the defective areas of the building's exterior wall and the installation location of the expansion sleeves; inserting anchor rods through the integrated thermal insulation panel into the expansion sleeves, thereby installing the integrated thermal insulation panel onto the building's exterior wall; using an ultrasonic testing instrument to detect the bonding density between the insulation substrate and the building's exterior wall; filling any detected gaps using high-pressure grouting; and repairing any areas with air bubbles or cracks.

[0025] By adopting the above technical solutions, modeling based on measured data of building exterior walls, and using laser cutting technology to cut the insulation substrate into irregular shapes and prefabricate anchor holes and grooves, the insulation substrate can be adapted to the shape of the building exterior wall. Repairing defects in the building exterior wall and cleaning surface dust and oil stains can improve the fit between the integrated insulation panel and the building exterior wall. Positioning the installation location of the integrated insulation panel and pre-embedding expansion sleeves and applying interface agent facilitates accurate installation and enhances adhesion. The anchor rod passes through the insulation substrate and screws into the expansion sleeve to install the insulation substrate, thus fixing the integrated insulation panel. Applying a decorative surface layer to one side of the insulation substrate to form an integrated insulation panel can improve the structure of the integrated insulation panel. Using an ultrasonic testing instrument to detect the bonding density, high-pressure grouting to fill gaps, and repairing air bubbles and cracks can ensure the installation quality and insulation performance of the integrated insulation panel and the building exterior wall.

[0026] In summary, this application includes at least one of the following beneficial technical effects: Setting insulation blocks inside the pressure groove can reduce thermal bridges caused by heat conduction from anchor rods and improve the insulation performance of the integrated insulation panel. After the anchor rod is passed through the anchor hole and screwed into the expansion sleeve, the connecting rod is taken out. The tapered end of the drive rod will puncture the storage bag, causing the polyurethane foam to leak and foam to form an insulation block. The insulation block can fill the pressure groove, thereby reducing the gap between the insulation block and the pressure groove and improving the insulation effect. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses an integrated thermal insulation panel and its construction method.

[0031] Reference Figure 1 , Figure 2 The integrated insulation panel includes an insulation substrate 1, on the side of the insulation substrate 1 away from the building's exterior wall, a decorative layer 2 is fixedly installed. In this embodiment, the decorative layer 2 is an anodized aluminum panel, and the surface of the anodized aluminum panel is treated with a fluorocarbon spraying process to enhance weather resistance.

[0032] Reference Figure 3 , Figure 4 The insulation substrate 1 has multiple anchoring holes 3, and the side of the insulation substrate 1 near the decorative layer 2 has multiple pressing grooves 4 and placement grooves 5. The placement grooves 5, pressing grooves 4 and anchoring holes 3 are coaxially arranged in a one-to-one correspondence, and the diameters of the placement grooves 5, pressing grooves 4 and anchoring holes 3 decrease sequentially.

[0033] Reference Figure 4 , Figure 5 An anchor rod 6 is slidably inserted through the anchor hole 3, and a pressure plate 7 is fixedly installed at one end of the anchor rod 6. An expansion sleeve 8 is provided at the other end of the anchor rod 6, and the anchor rod 6 is threaded through the expansion sleeve 8.

[0034] The expansion sleeve 8 is pre-embedded in the building's exterior wall. The anchor rod 6 passes through the anchor hole 3 and is screwed into the expansion sleeve 8, thereby pressing the pressure plate 7 against the pressure groove 4 close to the inner wall of the building's exterior wall, thus fixing the insulation base plate 1 to the building's exterior wall.

[0035] Reference Figure 4 , Figure 5 The pressure plate 7 is provided with a connecting rod 9, a first mounting block 10, a second mounting block 11, and a drive rod 12. One end of the connecting rod 9 is fixedly connected to the first mounting block 10. The second mounting block 11 has a mounting groove 13 for the first mounting block 10 to be inserted into with damping. There are multiple drive rods 12, which are spaced apart circumferentially along the second mounting block 11, and the drive rods 12 are fixedly connected to the second mounting block 11.

[0036] The pressure plate 7 has a first drive groove 14 on the side away from the anchor rod 6 for the second mounting block 11 to pass through for damping, and the pressure plate 7 also has a second drive groove 15 on the side away from the anchor rod 6 for the drive rod 12 to pass through for damping.

[0037] Insert the second mounting block 11 into the first drive groove 14, insert the drive rod 12 into the second drive groove 15, and then rotate the connecting rod 9 to drive the anchor rod 6 to rotate, thereby facilitating the screwing of the anchor rod 6 into the expansion sleeve 8.

[0038] Reference Figure 6 , Figure 7 The placement slot 5 is equipped with a baffle plate 16, and the baffle plate 16 has an inlet and outlet hole 17 for the connecting rod 9 to slide through.

[0039] Reference Figure 4 , Figure 7 A limit block 18 is fixedly installed at the end of the connecting rod 9 away from the pressure plate 7. The cross-sectional area of ​​the second mounting block 11 gradually increases from one side to the other of the connecting rod 9. The second mounting block 11 is used for damping insertion into the inlet and outlet.

[0040] After screwing the anchor rod 6 into the expansion sleeve 8, pull the connecting rod 9 out of the inlet and outlet. The connecting rod 9 moves the second mounting block 11 and the drive rod 12 away from the pressure plate 7. After the connecting rod 9 is pulled out of the inlet and outlet, the second mounting block 11 is blocked by the baffle plate 16, the first mounting block 10 separates from the second mounting block 11, and the second mounting block 11 blocks the inlet and outlet.

[0041] Reference Figure 4 , Figure 5 A storage bag 19 is fixedly installed between the pressure plate 7 and the baffle plate 16, and the storage bag 19 contains polyurethane foam. The storage bag 19 is a two-component, independently packaged bag, containing isocyanate prepolymer and polyether polyol. After the storage bag 19 is punctured, the isocyanate prepolymer and polyether polyol mix to form polyurethane foam. The end of the drive rod 12 away from the connecting rod 9 is tapered for puncturing the storage bag 19.

[0042] In this application, after the pressure plate 7 and the baffle plate 16 move away from each other, the storage bag 19 is taut and does not rupture. When the connecting rod 9 is pulled out from the inlet / outlet, the connecting rod 9 drives the second mounting block 11 and the drive rod 12 away from the pressure plate 7, thereby causing the conical end of the drive rod 12 to puncture the storage bag 19, and polyurethane foam flows out to form the insulation block 20. The insulation block 20 is located between the baffle plate 16 and the pressure plate 7, and the insulation block 20 fills the interior of the pressure groove 4, thereby improving the insulation effect of the integrated insulation panel.

[0043] In another embodiment, when the shielding plate 16 and the pressure plate 7 move away from each other, the storage bag 19 is pulled apart, causing the storage bag 19 to rupture and the polyurethane foam to flow out and foam to form the insulation block 20.

[0044] Reference Figure 5 , Figure 7 The pressure plate 7 has multiple leakage holes 21, which are connected to the anchoring holes 3. When the polyurethane foam flows out of the storage bag 19, some of the polyurethane foam flows into the anchoring hole 3 from the leakage holes 21, which helps to fill the gaps inside the anchoring hole 3 and improve the insulation effect.

[0045] Reference Figure 1 , Figure 2 The insulation substrate 1 has a slot 22 on its periphery, and a first sealing sheet 23 is fixedly installed on the inner wall of the slot 22. The slot 22 allows two insulation substrates 1 to be spliced ​​together, thereby extending the length of the gap between two adjacent insulation boards. The first sealing sheet 23 then seals the gap, thereby improving the waterproof performance.

[0046] In another embodiment, the first sealing sheet 23 is provided with a second sealing sheet, and the peripheries of the first sealing sheet 23 and the second sealing sheet are fixedly connected to each other. A talc powder layer is filled between the first sealing sheet 23 and the second sealing sheet. When the two insulation boards 1 are spliced ​​together, the talc powder layer facilitates the relative sliding of the first sealing sheet 23 and the second sealing sheet, thereby reducing the resistance encountered when the two insulation boards are spliced ​​together.

[0047] The construction method of the integrated insulation panel, using the integrated insulation panel of the present application embodiment, includes the following steps: Step S1: Based on the measured data of the building exterior wall, model the insulation substrate 1 using laser cutting technology during the board production stage, and prefabricate the anchoring holes 3 and the pressure grooves 4.

[0048] Step S2: For defects in the building's exterior walls, use localized point chiseling and polymer cement mortar repair techniques. Use high-pressure air to clean the surface dust and oil stains on the exterior walls.

[0049] Step S3: Locate the installation position of the integrated thermal insulation panel on the exterior wall of the building and pre-embed the expansion sleeve 8 in the exterior wall of the building; Step S4: Apply interface agent to the defective parts of the building exterior wall and the installation position of the expansion sleeve 8; Step S5: Anchor rod 6 passes through the integrated insulation panel and is screwed into expansion sleeve 8, thereby installing the integrated insulation panel on the exterior wall of the building; Step S6: Use an ultrasonic testing instrument to test the bonding density between the thermal insulation substrate 1 and the building exterior wall. Fill the detected gaps with high-pressure grouting and repair any areas with air bubbles or cracks.

[0050] The implementation principle of the integrated thermal insulation panel and its construction method in this application is as follows: Low thermal conductivity anchor rods 6, in conjunction with the insulation block 20 within the pressure groove 4, prevent heat transfer through the anchor rods 6. Simultaneously, by setting up structures such as the placement groove 5, baffle plate 16, connecting rod 9, storage bag 19, and drive rod 12, the function of on-site foaming to form the insulation block 20 is achieved, improving the fit between the insulation block 20 and the pressure groove 4 and the thermal insulation effect. Furthermore, the slot 22 and first sealing sheet 23 structure on the periphery of the insulation substrate 1 enhance the connection stability and sealing performance between the integrated thermal insulation panels, further improving the thermal insulation and waterproofing performance of the entire building's exterior wall.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
