Description
Technical Field
The invention relates to the technical field of building construction, in particular to a method and a structure for repairing and reinforcing falling, cracking and leakage of a plate heat-insulating system.
Background
Under normal conditions, the pasting mode of the external wall board heat-insulating system is divided into two modes of point-frame pasting and strip-type pasting, namely point-pasting and full-pasting, the pasting is taken as a main body to bear force, and a plastic anchor bolt is taken as an auxiliary. In northern area, usually the outer wall basic unit does not whitewash and makes level, therefore basic unit wall face roughness is relatively poor, and the heated board is pasted to ordinary point of use mode of gluing to solve outer heated board plane roughness problem. In addition, the point-sticking points use bonding mortar as a leveling material, so that the area of the heat-insulation board stuck to the foundation wall is often insufficient, and the standard requirement cannot be met.
The main problems of the existing pasting mode of the external wall board heat-insulation system are as follows: on one hand, the anti-cracking capability of a protective layer of the heat preservation system is insufficient, and the anti-cracking protective layer is easy to crack under the action of temperature difference and environment humidity, on the other hand, the performance difference between a heat preservation plate and the protective layer in the heat preservation system is large, the cooperative matching performance is not good (the heat conductivity coefficient difference is large, organic and inorganic materials are adopted, and the like), and the interfaces of the heat preservation plate and the bonding mortar and the heat preservation plate and the protective layer are easy to delaminate.
After insulation system protective layer fracture, the rainwater gets into insulation system, freeze thawing cycle and steam circulation, aggravate heated board and bonding mortar, heated board and protective layer interface punishment layer destruction, the protective layer fracture, wind gets into insulation system, because insulation system has the cavity, the effect of negative wind pressure, insulation system destroys from protective layer or heated board department, the phenomenon of coming off appears, then the wall skin drops very often. The rock wool heat preservation system is A-level fireproof, is relatively common in use, but the flat wire heat preservation plate is poor in safety and easy to fall off, people and objects are often injured due to the phenomenon, and no safe, reliable, ecological and environment-friendly solution exists at present.
The conventional thinking mode is to increase the number of plastic anchor bolts or increase the adhering area of the heat-insulating board and the base layer or rework the original heat-insulating system after the heat-insulating board is removed.
1. And a method for reinforcing by increasing the number of the heat-preservation anchor bolts and improving the anchoring effect is adopted. The method has the advantages that no adhesive layer is arranged under the base of the heat-insulating anchor bolt, the cavity part of the anchor bolt has no supporting function and restriction, the outer heat-insulating system has dead weight and wind and earthquake functions, and is easy to deform, unstable in anchoring, poor in reliability, low in single-nail pulling force and poor in reinforcing effect; in addition, the thickness of the outer anchor plate of the heat-preservation anchor bolt is large, the whole surface of the outer anchor plate of the heat-preservation anchor bolt needs to be covered thickly after being reinforced, the outer anchor plate of the heat-preservation anchor bolt is buried, the outer anchor plate of the heat-preservation anchor bolt needs to be prevented from cracking, the self weight is integrally increased, if the reinforcement is not in place, the risk is not reduced, namely the reinforcement is not carried out, the risk cannot be controlled, if the whole surface of the outer anchor plate of the heat-preservation anchor bolt is not covered after being reinforced, the surface; the method has the advantages of easy deformation, unstable anchoring, poor reliability, wind resistance and shock resistance and poor reinforcing effect.
2. And a method for reinforcing by increasing the adhering area is adopted. And after drilling, injecting a bonding material to increase the bonding area of the insulation board and the foundation wall for reinforcement. Because this type of heat preservation system is the cavity, and the outer wall basic unit does not whitewash and makes level, and conventional bonding class material is from great, directly pours into unable shaping into, and almost all hangs the drip down, and the technology can not be realized, in addition, supposes to realize, pours into in the cavity and also hardly guarantees and basic wall body and heated board bonding simultaneously firmly. The foaming agent light material is selected as the bonding material, the injection amount of the foaming agent and the range of the bonding surface are not well controlled, the injection position is also not well controlled, the post-expansion of the foaming agent is 30 percent, and the post-expansion process can damage the bonding surface of the original bonding mortar to reduce the bonding force or cause the bonding insulation board to bulge, the bonding is uneven, the reinforcing quality is uncontrollable and has no guarantee.
3. The original thermal insulation system is reworked after the shoveling, the method is complicated, the interference is large, the construction waste is large, the shoveling process has potential safety hazard, and the cost is high.
