Mankate published an article a few days ago, referring to some situations after the Wenchuan earthquake. Some readers wrote to us that they had encountered earthquakes in their own homes too. Although it did not destroy the houses, there were some inclinations and cracks in the walls. Will this situation cause hidden danger to living afterwards? We think that we need to reinforce our houses after the earthquake in order to be safe. And we also need to avoid the loading becoming bigger and bigger after the wall inclining. There will be some unexpectable troubles. Now let’s talk about how to deal with the problems of wall in our houses.
According to China's building wall design specifications, "Concrete Structure Design Code" GB50010-2010, the wall is divided into load-bearing walls and non-load-bearing walls. If the non-load-bearing walls have some problems, we can use filling sealant MKT-SAF to fill them. If the load-bearing walls have some problems, it is much more complex. The more common cases of wall damage are cracking and skewing. If conditions allow, you can construct the column structure directly to the wall, set the structure column in the four corners of the outer wall, which should ensure that the structural column and the ring beam are closely linked to the wall.
Another method is planting bars matched with the carbon fiber cloth reinforcement method. Firstly we must repair the wall cracks. Here we recommend Mankate slot filling adhesive and carbon fiber cloth. After repairing the wall cracks, we should set the columns at the four corners of the house, the corner of the outer wall, four corners of the stairwell and other places. And we select a reliable planting anchorage glue (such as Nanjing Mankate MT500 anchorage glue), in accordance with the requirements of the design drawings to drill the holes. We insert the planting anchorage glue into the pre-drilled holes, and then insert the reinforcing bar, slowly rotate it into the holes clockwise when implanting the reinforcing bar until there is a little glue overflowing. Let it stand still until the glue is solidified. Don’t touch the steel bars during this period.
Above are some commonly used and relatively reliable wall reinforcement methods. Besides, there are some other ways. But the impacts on the interior space are too large, so they are not recommended. For example, set rick door or ring beam, concrete reinforcement, etc. The products like filling sealant, carbon fiber cloth and anchorage glue mentioned in the article can be purchased in Nanjing Mankate. If your home walls need reinforcement, welcome to Nanjing Mankate Technology Co., Ltd.!
