Description

Technical Field

[0001] This utility model belongs to the technical field of building exterior wall repair tools, specifically relating to a dry-hanging exterior wall panel device for repairing exterior walls of buildings in cold regions. Background Technology

[0002] Building exterior walls have the basic function of preventing rainwater and snowmelt from penetrating the wall structure, and should also possess properties such as freeze-thaw resistance, high and low temperature resistance, and wind load resistance. However, after prolonged use, existing building exterior walls often experience peeling and cracking, thus requiring repair. Existing repair methods, however, have the following problems:

[0003] 1. When the outer skin of the exterior wall peels off, it is necessary to remove part or all of the outer skin. When repainting after partial removal, the color of the new outer skin will be inconsistent with the old outer skin, resulting in poor aesthetics. When the outer skin is completely removed, the construction time is long, the removal quality is uneven, and the paint may peel off later.

[0004] Second, when cracks appear in the exterior wall, they need to be filled by grouting. However, when the exterior wall is used in a large temperature difference environment of high temperature or cold, the repaired part is prone to secondary cracking, causing the exterior wall to crack again. The cracks in the exterior wall will become larger and larger, and the repair effect will not be achieved.

[0005] 3. When bonding thermal insulation curtain wall panels to the exterior wall, the original exterior wall surface needs to be removed to improve adhesion. Otherwise, the adhesion will be unreliable. When using bolts or brackets for installation, the gaps between the thermal insulation curtain wall panels need to be waterproofed. Otherwise, the thermal insulation curtain wall panels will have poor waterproof performance. Utility Model Content

[0047] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0048] Specific implementation method one: Combining Figure 1 The illustration illustrates this specific embodiment. This embodiment uses a horizontal sealing keel 1 to achieve the installation and sealing of the insulated curtain wall panel 3, while a vertical sealing keel 2 is used to seal the insulated curtain wall panel 3 and improve the stability of the horizontal sealing keel 1. Specifically, the technical solution includes a horizontal sealing keel 1, a vertical sealing keel 2, and an insulated curtain wall panel 3. The horizontal sealing keel 1 is fixedly installed on the exterior wall with bolts, such as... Figure 11 As shown, the horizontal sealing keel 1 can be fixed to the exterior wall and also fix the crack 4 on the exterior wall, making it less likely for the crack to extend or crack again. A longitudinal sealing keel 2 is set between the two horizontal sealing keels 1, which can support the two horizontal sealing keels 1 and prevent the two horizontal sealing keels 1 from deforming. The longitudinal sealing keel 2 is fixedly connected to the exterior wall. A curtain wall panel installation groove is formed between the two horizontal sealing keels 1. The insulated curtain wall panel 3 is installed in the curtain wall panel installation groove. The longitudinal sealing keel 2 is set between the two insulated curtain wall panels 3. The insulated curtain wall panel 3 is sealed to the horizontal sealing keel 1 and the longitudinal sealing keel 2. The insulated curtain wall panel 3 can be installed in the curtain wall panel installation groove and can also be bonded to the exterior wall, which can improve the stability of the installation of the insulated curtain wall panel 3. At the same time, the insulated curtain wall panel 3 is sealed to the horizontal sealing keel 1 and the longitudinal sealing keel 2, which can improve the waterproof performance.

[0049] In this specific embodiment, a horizontal sealing keel 1 is installed on the exterior wall. Then, according to the width of the insulated curtain wall panel 3, another horizontal sealing keel 1 is installed. After installation, the insulated curtain wall panel 3 is installed between the two horizontal sealing keels 1, achieving a seal for the insulated curtain wall panel 3 through the horizontal sealing keels 1. After one insulated curtain wall panel 3 is installed, a longitudinal sealing keel 2 is installed. The longitudinal sealing keel 2 is fixed to the exterior wall with bolts or adhered to the exterior wall with expanding foam or other adhesives. The longitudinal sealing keel 2 achieves a seal for the insulated curtain wall panel 3. This installation is repeated. Figure 11 As shown, when there is a gap 4 in the wall, the horizontal sealing keel 1 can fix the gap 4, making it less likely for the gap 4 to crack.

[0050] Specific Implementation Method Two: Combining Figure 2 , Figure 3 The illustration shows this specific embodiment, which is a further limitation of Specific Embodiment 1. In this specific embodiment, the horizontal sealing keel 1 can realize the installation and sealing of the thermal insulation curtain wall panel 3, and at the same time facilitate the fixing of the horizontal sealing keel 1 to the exterior wall. The specific technical solution adopted is as follows: The horizontal sealing keel 1 includes a base plate 1-1, a connecting plate 1-2, and an outer plate 1-3; the connecting plate 1-2 is fixedly connected to the middle of the inner side wall of the base plate 1-1, and the outer end of the connecting plate 1-2 is fixedly connected to the middle of the inner side wall of the outer plate 1-3. The base plate 1-1, the connecting plate 1-2, and the outer plate 1-3 form an I-shaped keel. The grooves on both sides of the I-shaped keel can realize the installation of the thermal insulation curtain wall panel 3, that is, the space between the base plate 1-1 and the outer plate 1-3 is... The curtain wall panel mounting groove has several sealing strip mounting grooves 1-11 on the inner side wall of the base plate 1-1 and symmetrical sealing strip mounting grooves 1-31 on the inner side wall of the outer plate 1-3. Sealing strips 1-4 are installed in both sealing strip mounting grooves 1-11 and 1-31. Sealing strips 1-4 can achieve sealing of the thermal insulation curtain wall panel 3. Several fixing through holes 1-12 are evenly opened on the upper and lower sides of the inner side wall of the base plate 1-1. The outer end of the fixing through holes 1-12 is connected to a countersunk hole 1-13. The fixing through holes 1-12 can fix the base plate 1-1. Shock-absorbing rubber pads 1-21 are bonded to both outer side walls of the connecting plate 1-2. Shock-absorbing rubber pads 1-21 can achieve shock absorption of the thermal insulation curtain wall panel 3.

[0051] As described above, in order to improve the waterproofness of the exterior wall, an inclined drainage groove 1-32 is provided on the outer panel 1-3. The drainage groove 1-32 is higher on the inside and lower on the outside. The bottom of the inner end of the drainage groove 1-32 is on the same plane as the upper end surface of the connecting plate 1-2. When the seal of the transverse sealing keel 1 is partially loose, water enters the transverse sealing keel 1 and is discharged through the drainage groove 1-32, making it difficult for water to enter the exterior wall and improving the waterproofness.

[0052] In this specific embodiment, the transverse sealing keel 1 is fixed by the base plate 1-1. When fixed, as follows... Figure 3 As shown, the drainage groove 1-32 is on the upper side to facilitate drainage later. When fixing the base plate 1-1, bolts are used to pass through the fixing through hole 1-12 to fix the base plate 1-1 to the wall. At the same time, in order to improve the fixing strength, a sealing adhesive can be applied to the bottom of the base plate 1-1 when fixing it. Fixing and sealing with the external wall are achieved by adhesive bonding. After the base plate 1-1 is installed, the sealing strip 1-4 is installed in the sealing strip installation groove 1-11 and the sealing strip installation groove 2-31. The sealing of the thermal insulation curtain wall panel 3 is achieved by the sealing strip 1-4. When water enters from the horizontal sealing keel 1, the water will be discharged from the drainage groove 1-32.

[0053] Specific implementation method three: Combining Figure 4 The illustration shows this specific embodiment, which is a further limitation of embodiment one or two. In this specific embodiment, sealing is achieved through sealing strip 1-4, and the specific technical solution is as follows: The sealing strip 1-4 includes a T-shaped rubber block 1-41 and an arc-shaped sealing rubber body 1-42. The T-shaped rubber block 1-41 and the arc-shaped sealing rubber body 1-42 are integrally formed and connected. The T-shaped rubber block 1-41 can be installed in the sealing strip mounting groove one 1-11 and the sealing strip mounting groove two 1-31. During sealing, sealing is achieved through the arc-shaped sealing rubber body 1-42. The T-shaped rubber block 1-41 and the arc-shaped sealing rubber body 1-42 are provided with cavities 1-43. When the arc-shaped sealing rubber body 1-42 comes into contact with the thermal insulation curtain wall panel 3, its arc-shaped sealing rubber body 1-42 deforms under force and seals with the thermal insulation curtain wall panel 3. Its cavity 1-43 can realize the deformation of the arc-shaped sealing rubber body 1-42 within a certain range.

[0054] In this specific embodiment, T-shaped rubber blocks 1-41 are installed in the sealing strip mounting groove 1-11 and the sealing strip mounting groove 2-31 of the horizontal sealing keel 1. At this time, the arc-shaped sealing rubber body 1-42 can contact and seal with the thermal insulation curtain wall panel 3, which can improve the sealing performance.

[0055] Specific implementation method four: Combination Figure 5 , Figure 6 , Figure 7The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, or three. In this specific embodiment, the longitudinal sealing keel 2 can support the two transverse sealing keels 1 and simultaneously seal the insulated curtain wall panel 3. The specific technical solution adopted is as follows: The longitudinal sealing keel 2 includes a longitudinal plate 2-1, a support strip 2-2, and fixed supports 2-3; the support strip 2-2 is fixedly connected to the middle of the rear end face of the longitudinal plate 2-1, and the support strip 2-2 can provide effective support. Both sides of the inner wall of the longitudinal plate 2-1 are... A sealing strip mounting groove 2-11 is provided, and a sealing strip 1-4 is installed in the sealing strip mounting groove 2-11. A fixed support leg 2-3 is fixedly installed at the bottom of the support strip 2-2, and the fixed support leg 2-3 can be fixed to the wall. The bottom of the fixed support leg 2-3 is provided with a concave arc-shaped glue groove 2-33. A fixed through hole 2-31 is symmetrically provided on the fixed support leg 2-3. The outer end of the fixed through hole 2-31 is connected to a countersunk hole 2-32. The fixed support leg 2-3 can be installed by bolts or by adhesive according to the site conditions.

[0056] Meanwhile, in order to improve the shock absorption of the thermal insulation curtain wall panel 3, shock-absorbing rubber pads 1-21 are bonded to the two side walls of the support strip 2-2. The shock absorption is achieved through the shock-absorbing rubber pads 1-21, which can improve the shock absorption of the thermal insulation curtain wall panel 3 and make it less likely to generate noise.

[0057] In this specific embodiment, the longitudinal sealing keel 2 is installed as follows: Figure 8 As shown, a longitudinal sealing keel 2 is installed between two horizontal sealing keels 1. The fixing feet 2-3 of the longitudinal sealing keel 2 are glued to the exterior wall or fixed to the wall by bolts, which can achieve the fixing of the longitudinal sealing keel 2. At this time, a sealing strip 1-4 is installed in the sealing strip installation groove 2-11, and the sealing of the thermal insulation curtain wall panel 3 is achieved by the sealing strip 1-4.

[0058] Specific Implementation Method Five: Combining Figure 9 , Figure 10This embodiment illustrates a further limitation of embodiments one, two, three, or four.

The specific technical solution is as follows: The insulated curtain wall panel 3 includes an insulated outer panel 3-1 and a reinforcing fixing plate 3-2; the reinforcing fixing plate 3-2 is bonded to the inner wall of the insulated outer panel 3-1, enabling it to be bonded and fixed to the outer wall. The insulated outer panel 3-1 includes a decorative panel 3-11, a waterproof layer 3-12, an insulation board 3-13, and a base plate 3-14; the inner wall of the decorative panel 3-11 is provided with a waterproof layer 3... -12, the waterproof layer 3-12 is bonded to the insulation board 3-13. A base plate 3-14 is bonded to the inner wall of the insulation board 3-13. The base plate 3-14 uses existing sound insulation board, which can improve sound insulation. Decoration is achieved by decorative board 3-11, which is aluminum plate or other board material. The waterproof layer 3-12 can achieve waterproofing, and the insulation board 3-13 can achieve heat insulation, which can improve the heat insulation of the exterior wall. The reinforcing fixing plate 3-2 has glue injection grooves 3-21 evenly opened. Several connecting columns 3-22 are evenly fixed in the glue injection grooves 3-21. The glue injection grooves 3-21 can achieve glue injection, and the connecting columns 3-22 can improve the adhesion of the glue.

[0059] In this specific embodiment, when installing the thermal insulation curtain wall panel 3, adhesive is injected into the adhesive injection groove 3-21.
