Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method and structure for repairing and reinforcing the shedding, cracking and leakage of a plate thermal insulation system. Background Art

[0002] Normally, the external wall insulation system is pasted in two ways: point-frame pasting and strip pasting, also known as point pasting and full pasting. Pasting is the main force, supplemented by plastic anchor bolts. In northern regions, the external wall base is usually not painted and leveled, so the flatness of the base wall is poor. Usually, the insulation board is pasted by point pasting to solve the problem of the flatness of the external insulation board surface. In addition, the point pasting point uses bonding mortar as the leveling material, so the pasting area between the insulation board and the base wall is often insufficient and cannot meet the requirements of the specification.

[0003] The main problems with the current pasting method of exterior wall panel insulation systems are: on the one hand, the insulation system's protective layer has insufficient crack resistance, and the crack-resistant protective layer is prone to cracking under temperature differences and environmental dryness and wetness; on the other hand, the insulation board and the protective layer in the insulation system have large performance differences, and poor coordination (large differences in thermal conductivity, organic and inorganic materials, etc.), and stratification is very likely to occur at the interface between the insulation board and the bonding mortar, and between the insulation board and the protective layer.

[0004] After the insulation system's protective layer cracks, rainwater enters the insulation system, and the freeze-thaw cycle and water vapor cycle aggravate the delamination damage at the interface between the insulation board and the bonding mortar, and the insulation board and the protective layer. The protective layer cracks, and wind enters the insulation system. Due to the existence of cavities in the insulation system and the negative wind pressure, the insulation system is damaged from the protective layer or insulation board, and there is a phenomenon of peeling, which is often called wall peeling. Rock wool insulation system is commonly used because it is Class A fireproof, but flat wire insulation board has poor safety and is easy to fall off. This phenomenon is often reported to injure people and damage property. There is currently no safe, reliable, and environmentally friendly solution.

[0005] The conventional way of thinking is to increase the number of plastic anchors or increase the bonding area between the insulation board and the base layer or to remove it and redo the original insulation system.

[0006] 1. The method of increasing the number of thermal insulation anchors and improving the anchoring effect for reinforcement is adopted. This method has the problems of no bonding layer under the thermal insulation anchor base, no support and constraint in the anchor cavity, easy deformation due to the deadweight, wind and earthquake of the external thermal insulation system, unstable anchoring, poor reliability, low single nail pull-out force, and poor reinforcement effect; in addition, the thickness of the outer anchor plate of the thermal insulation anchor is large, and the entire surface needs to be covered with a thicker cover after reinforcement, and the outer anchor plate of the thermal insulation anchor needs to be buried, and it is necessary to ensure that the outer anchor plate of the thermal insulation anchor does not crack, and the overall deadweight is increased. If the reinforcement is not in place, not only the risk will not be reduced, but it is equivalent to no reinforcement, and the risk cannot be controlled. If the entire surface is not covered after reinforcement, the surface flatness is poor, and the appearance of the exterior finish is completely different; this method of reinforcement is easy to deform, unstable anchoring, poor reliability, wind resistance, and earthquake resistance, and the reinforcement effect is poor.

[0007] 2. Use the method of increasing the bonding area for reinforcement. After drilling, inject adhesive materials to increase the bonding area between the insulation board and the foundation wall for reinforcement. Since this type of insulation system is a cavity, the exterior wall base is not painted and leveled. Conventional adhesive materials are heavy and cannot be formed by direct injection. Almost all of them hang down and drip, and the process cannot be realized. In addition, assuming it can be realized, it is difficult to ensure that the foundation wall and the insulation board are firmly bonded at the same time when injected into the cavity. Lightweight materials such as foaming agents are selected as bonding materials. Since the amount of foaming agent injection and the range of the bonding surface are difficult to control, the injection position is also difficult to control. The foaming agent expands by 30%. The post-expansion process will damage the original bonding mortar bonding surface, reduce the bonding force or cause the insulation board to swell, and the bonding is uneven. The reinforcement quality is uncontrollable and unguaranteed.

[0008] 3. Redoing the original insulation system after demolition is a complicated method with great interference and a lot of construction waste. There are safety hazards in the demolition process and the cost is high. Summary of the invention

[0009] One of the technical problems to be solved by the present invention is to provide a method for repairing and reinforcing the shedding, cracking and leakage of the existing board insulation system: there is no adhesive layer under the insulation anchor base, the anchor cavity has no support and constraint, the external insulation system is easy to deform due to its own weight, wind and earthquake, unstable anchoring, poor reliability, low single nail pulling force, uncontrollable and unguaranteed quality, and poor reinforcement effect. There are safety hazards in the removal process, a lot of construction waste, high cost and no environmental protection, which is not conducive to resource conservation.

There are safety hazards in the removal process, there is a lot of construction waste, the cost is high and it is not environmentally friendly, which is not conducive to resource conservation.
