Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a facade repair structure based on facade facing brick veneer. Background Art

[0002] At present, many buildings with tiled facades have peeling between the tiles and the wall, damage and cracking of tiles, and through cracks in the tile joints due to their age. This not only affects the visual appearance of the building, but also causes serious water leakage in the exterior wall. When the tiles fall off, it will threaten the safety of pedestrians and vehicles, posing a serious safety hazard. This phenomenon is common in old residential areas in urban areas and self-built buildings in rural areas.

[0003] For the above-mentioned exterior wall problems, the most common method currently adopted is to renovate the entire facade, that is, to remove all the original facade tiles, repair the cracks in the base layer, assist in the construction of a local waterproof layer, and finally restore the tile finishing layer. The disadvantages of this method are that it is less environmentally friendly, generates more garbage, has a high maintenance cost, and when there is an insulation system on the facade, removing the tiles will easily cause pulling damage to the insulation layer, so this method has problems in terms of feasibility, environmental protection, and economy.

[0004] Therefore, technicians in this field urgently need to provide a facade repair structure based on facade facing brick veneer to solve the facade leakage problem caused by the falling off and cracking of facade tiles and ensure the safety and aesthetics of the facade wall tiles. Utility Model Content

[0005] The purpose of this application is to provide a facade repair structure based on facade facing brick veneer, which adds structural layers to the original facade facing brick surface, eliminates water leakage and makes the facade more beautiful, simple in structure, environmentally friendly and economical.

[0006] A facade repair structure based on facade facing brick veneer comprises a wall and an insulation layer and a tile surface layer laid outside the wall, wherein the brick joints of the tile surface layer are filled with a filling layer, and an adhesive layer, an anti-cracking layer, a waterproof layer and a putty layer are laid on the surfaces of the tile surface layer and the filling layer in sequence.

[0007] Furthermore, a primer is coated on the putty layer, and a decorative layer is laid on the primer.

[0008] Furthermore, the decorative layer is a topcoat or a stone-like paint.

[0009] Furthermore, the filling layer is anti-cracking mortar.

[0010] Furthermore, the bonding layer is a wall solidifier or an interface agent.

[0011] Furthermore, the anti-cracking layer is an anti-cracking mortar containing mesh cloth.

[0012] Furthermore, the waterproof layer is an acrylic polymer waterproof coating.

[0013] Beneficial effect: The facade repair structure based on the facade facing brick finish in the present application realizes the leakage prevention and beauty of the facade by reinforcing and repairing the original facade facing bricks, adding a crack-resistant and waterproof structural layer and a decorative layer that matches the bonding strength of the facade; it does not damage the original insulation layer and tile surface layer of the facade, and has a simple structure, is environmentally friendly and economical. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a cross-section of the facade restoration structure based on the facade brick veneer;

[0015] Figure 2 It is a partial enlarged view of the facade restoration structure based on the facade brick veneer. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Figure 1 and 2 The exterior facade repair structure based on the exterior facade brick veneer in this application is described in detail. It should be noted that the anti-crack mortar, wall solid, interface agent, acrylic polymer waterproof coating, putty, primer, topcoat, imitation stone coating and other building materials in this application are all commercially available.

[0017] like Figure 1 As shown, a facade repair structure based on facade facing brick veneer includes a wall 1 and an insulation layer 2 and a ceramic tile surface layer 3 laid on the outside of the wall 1, the brick joints of the ceramic tile surface layer 3 are filled with a filling layer 4, and the surfaces of the ceramic tile surface layer 3 and the filling layer 4 are laid with a wall solidification layer 5, an anti-cracking layer 6, a waterproof layer 7 and a putty layer 8 in sequence.

[0018] The surface of the tile surface layer 3 is first cleaned, and the filling layer 4 is used to fill and repair the brick joints, and the brick joints are filled and smoothed with anti-cracking mortar.

[0019] The bonding layer 5 is used to fill the cracks and damages of the tiles and enhance the bonding force and adhesive strength of the smooth tile surface layer 3. In this embodiment, the bonding layer 5 is a wall solid or interface agent.

[0020] An anti-cracking layer 6 is laid on the bonding layer 5. The anti-cracking layer 6 is an anti-cracking mortar containing a mesh cloth. A layer of alkali-resistant mesh cloth is pressed into the anti-cracking mortar, and then the mesh cloth is completely covered and smoothed with the anti-cracking mortar.

[0021] A waterproof layer 7 is laid on the anti-cracking layer 6. In this embodiment, the waterproof layer 7 is an acrylic polymer waterproof coating. The acrylic polymer waterproof coating has excellent weather resistance, heat resistance, and UV resistance, and is suitable for waterproofing of the exterior facade.

[0022] After the waterproof coating of the waterproof layer 7 is dried, a putty layer 8 is laid on the waterproof layer 7. The putty layer 8 can directly play a decorative role or a bonding role. Figure 1 As shown, the putty layer 8 plays a bonding role, a primer 9 is applied on the putty layer 8, and a decorative layer 10 is laid on the primer 9. In view of the bonding strength of each layer structure of the facade, the decorative layer 10 adopts a topcoat or a stone-like paint, and the stability of the facade is better.

[0023] The facade repair structure in the present application aims to solve the facade leakage problems caused by the falling off and cracking of facade tiles, as well as the safety and aesthetics of the facade wall tiles. It reinforces and repairs the original facade tiles, adds a crack-resistant and waterproof structural layer, and a decorative layer that matches the bonding strength of the facade, to achieve leakage prevention and aesthetics of the facade; it does not damage the original insulation layer and tile surface layer of the facade, and has a simple structure, is environmentally friendly and economical.
