First, how to repair the roof cracks and leaks?
1. See where the crack opens. Let's draw on the blackboard to determine the position. It extends outward about one meter along the outermost side of the panel and the main crack direction, which is the construction scope. In order to enter the next floor, we must cut the concrete slab. Then along the crack, let's cut a 20? 30 mm groove. We use lb-8 quick-setting cement to repair the cracks on the board. Repair the cracks on the back of the board in the same way. At this time, the repair material is lb-9 1 modified epoxy resin grouting fluid.
2. If the plate structure can't bear the weight or the cracking situation is still serious. We should repair and reinforce the boards. Apply a layer of cement slurry on the roof waterproof construction base to find its smooth layer. The volume is about 1.5 ~ 20 mm, and the thickness is 1:2.5.
3. In order to repair the waterproof layer of the building base, the waterproof layer on the surface of the original building should be considered when selecting materials, and the contact with the original waterproof layer should be greater than or equal to100 mm. It is best to lay a layer of pvc film similar to asphalt paper on his surface, which can play the role of isolation layer. It can also be used as a repair protective layer and decorative layer.
Second, the management of housing maintenance plan.
We should make a reasonable plan in advance to prevent the roof from leaking. Consider how to carry out maintenance from a scientific point of view. House maintenance and repair are indispensable, but in practice, house maintenance will have a new impact on houses in some places, leading to the failure of house maintenance. Therefore, when making a real plan, we should combine the theory of hypothesis with practical operation, and we can't talk on paper.
Maintenance is an indispensable part of the house maintenance plan. It is necessary to consider the content, implementation mode, personnel, material cost, quality assessment and other different levels in order to make a more comprehensive plan.
Bian Xiao concluded: We should also think about how to prevent problems while solving them. The problem of roof cracks and water leakage is well solved, but the best way is to make the problem not happen again. Therefore, it is very important to formulate a reasonable safeguard scheme. Eliminating and preventing problems can save us time to solve problems.
