Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall insulation repair, in particular to an extruded board exterior wall insulation hollowing cracking anti-leakage repair structure. Background Art

[0002] In recent years, with the rapid development of exterior wall insulation renovation projects, various exterior wall insulation construction methods have become more and more common, and the application of various insulation materials and adhesive materials has become more and more extensive. As a result, after a long period of time, due to environmental factors such as temperature difference, water vapor infiltration, material aging, negative wind pressure, and the quality of adhesive materials, the insulation layer and the building structure base surface will peel off and fall off, which not only seriously affects the appearance of the building's exterior wall, but also causes serious safety hazards. Among them, the hollowing of the insulation layer is the most direct factor causing the falling of the exterior wall insulation layer. Therefore, an exterior wall insulation hollowing repair structure is designed.

[0003] For example, Chinese patent CN215054199U, a structure for repairing hollow insulation of exterior wall, relates to the field of exterior wall insulation repair, and solves the problem that the existing exterior wall hollowing repair method needs to chisel out the old insulation layer and then re-hang the mesh and add finishing paint, which leads to a large amount of labor and material costs, generates construction waste, and the appearance of the new finish is inconsistent with the old finish. The utility model includes a penetrating reinforcement primer layer, a self-leveling expansion mortar layer, a polyurethane rigid foam insulation layer, an exterior wall anti-cracking and water-resistant putty layer, and an exterior wall paint layer, which are arranged in sequence from the inside to the outside. The dense expansion filler formed in the hollow exterior wall insulation layer makes the hollow exterior wall insulation layer and the exterior wall base surface tightly bonded together, effectively reducing the construction difficulty and construction risk, improving construction efficiency, while reducing the repair cost, and greatly reducing the risk of falling off caused by the hollowing of the exterior wall insulation layer. At the same time, the utility model does not generate construction waste, and the appearance of the new finish is unified with the old finish, thereby improving the aesthetics.

[0004] The above patent still has certain defects. This patent effectively reduces the difficulty and danger of construction, improves construction efficiency, and reduces repair costs.

[0037] See also Figure 4 In order to enhance the waterproof performance of the exterior wall body 1, the waterproof component 3 in this embodiment includes a reinforcement layer 301 bonded to the right side of the XPS insulation board 4, the right side of the reinforcement layer 301 is coated with a sealing layer 302, the right side of the sealing layer 302 is coated with a waterproof layer 303, the right side of the waterproof layer 303 is coated with a waterproof layer 304, and the right side of the waterproof layer 304 is coated with a wear-resistant layer 305.

[0038] In this embodiment, the reinforcement layer 301 is a mesh cloth layer, which is an ideal reinforcement material for cement concrete products, GRC wall panels, and GRC components.

The wear-resistant layer 305 is a UV coating layer, which does not contain any volatile substances, has high hardness, good wear resistance, and is scratch-resistant and friction-resistant.

[0039] The working principle of the above embodiment is:

[0040] (1) When repairing the insulation structure of the exterior wall, it is necessary to replace the XPS insulation board 4, retract the wires and remove the outer waterproof component 3 to expose all the auxiliary boards 209, then pull the auxiliary board 209 to the right so that the auxiliary board 209 drives the sealing board 208 to move together, and at the same time, the plug rod 205 moves together with the sealing board 208. During the movement of the sealing board 208, the XPS insulation board 4 pushes the limit block 207 into the inside of the sealing board 208 and compresses the limit spring 206 through the limit block 207. When the sealing board 208 is completely separated from the inside of the XPS insulation board 4, the limit spring 206 returns the limit block 207 to its original position. When the plug rod 205 is completely separated from the XPS insulation board 4, the hexagonal wrench can be inserted into the socket to rotate The hexagonal wrench drives the rotating rod 204 to rotate together, and the threaded sleeve 202 rotates with the rotating rod 204. The rotation of the threaded sleeve 202 drives the rotating rod 204 to move to the right. When the threaded sleeve 202 is in contact with the movable groove, it stops rotating. At this time, the screw 203 is completely separated from the threaded sleeve 202. Then the XPS insulation board 4 is pulled to the right to be completely separated from the positioning plate 201, and the XPS insulation board 4 can be taken out for replacement. The repair mechanism 2 cooperates with the positioning plate 201, the threaded sleeve 202, the screw 203 and the rotating rod 204, so that the staff can easily fix the XPS insulation board 4 on the exterior wall, or remove it from the exterior wall, so as to facilitate the staff to repair the XPS insulation board 4.

[0041] (2) The reinforcement layer 301 is a mesh cloth layer. The GRC product reinforcement mesh cloth is made of glass fiber woven fabric as the base material and is treated with a polymer alkali-resistant emulsion. The product has high strength and good alkali resistance. It can resist the corrosion of alkaline substances for a long time. It is an ideal reinforcement material for cement concrete products, GRC wall panels, and GRC components. Under the action of the reinforcement layer 301, the strength of the subsequent concrete after drying and solidification is enhanced. The sealing layer 302 is a waterproof mortar layer, also known as a cationic chloroprene latex waterproof and anti-corrosion material. It has good weather resistance, durability, impermeability, density and extremely high adhesion as well as extremely strong waterproof and anti-corrosion effects. It can resist corrosion from soda ash production media, urea, ammonium nitrate, seawater hydrochloric acid and acidic and alkaline salts. Under the action of the sealing layer 302, it blocks external liquids from penetrating and touching the XPS insulation board 4. The waterproof layer 303 is a polyurethane waterproof coating layer, which is made of polyurethane resin. A type of polymer waterproof coating as the main film-forming material has the characteristics of high strength, large elongation, good water resistance, green and environmental protection, dense coating, simple construction, etc. Under the action of the waterproof layer 303, the liquid on the outside is intercepted, thereby strengthening the anti-water seepage effect of the sealing layer 302. The waterproof layer 304 is a waterproof and breathable membrane layer, which is resistant to acids and alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, the waterproof and breathable membrane has the characteristic of high temperature resistance. The waterproof performance of the waterproof layer 303 is further enhanced by the waterproof layer 304. The wear-resistant layer 305 is a UV coating layer. UV coating is a truly green and environmentally friendly paint, does not contain any volatile substances, has high hardness, good wear resistance, scratch resistance, friction resistance, and can stand the test of time. Under the action of the wear-resistant layer 305, the outer coating is prevented from being worn away during long-term use, thereby causing the exterior wall to lose its waterproof ability.
