Is there a potential safety hazard in the column fracture deviation in the community?

This happened in a community in Tianhe District, Guangzhou. The owners of the community reported that two pillars on the first floor of their building were broken, and there was obvious displacement at the broken place, which made the owners of the building panic. The owner of this building also said that the two pillars of the 1 building began to break several years ago, and they reflected this situation to the property at that time. The answer they may get is that this is a normal phenomenon of concrete shrinkage. The owner didn't notice the fracture at that time, so he didn't pay attention to it deliberately. However, with the passage of time, this kind of fracture phenomenon has become more and more serious, and even to the point of displacement now, the owners who watched it panicked, so they reflected this situation to the property again, but the property company has not dealt with it so far.

As can be seen from the pictures of two columns on the 1 floor taken by the owner, these two exercise columns are located at the joint between the columns and the balcony on the second floor. One of the columns has a dislocation area of 7 ~ 8 cm wide, and the dislocation and fracture of the column can be clearly observed by naked eyes, which really worries the owners of this building. It is worth noting that under these two pillars is the leisure area of the community, where table tennis tables and some sports equipment are also placed, and there is a passage to the other side of the building, but no safety warning signs are seen at the scene. If these two pillars collapse, it will not only cause danger to the upstairs, but also cause harm to the people walking below.

According to an owner of this building, many people come here to exercise in the playground downstairs, and many people come in and out through the passage under the column. They didn't pay much attention to the small cracks on the two pillars before, but now the two pillars are obviously broken, so the residents in their building are afraid to pass under the two broken pillars at present. It is understood that this building has 18 floors. Except for 1 floor, there are 4 households on each floor from the second floor. In other words, in addition to 1 floor, there are 68 households above the second floor. Once there is any problem, the loss is very huge. Therefore, these owners have informed the residential property of this situation.

Another owner said that cracks appeared on two columns as early as 16, when the cracks were about one centimeter, so they reflected this situation to Guangzhou Meilin Ji Ye Property Management Co., Ltd., the property management company of the building, but the property did not take any specific action at that time, only telling their owners that the broken columns were decorative columns, not load-bearing columns, and would not have any impact on the structure of the whole building. However, their owners suggested that if it was not a load-bearing column, the property should issue an appraisal report to the owners, but the property did not make a follow-up response.

Until now, the degree of column fracture is increasing, and helpless owners can only complain through multiple channels. The property replied that they had consulted the original design engineer of Merrill Lynch Coastal Project. The answer given by the other party is that the deformation and dislocation of these two columns may be caused by the root growth of the underlying foundation of the green belt. Therefore, the property company replied to the owner that they decided to repair the eccentric column, but because of the need to dig the decorative column foundation, the property engineering department lacked relevant tools and needed to hire professionals to repair it.

The property also said that due to the complexity of the underground pipe network, they have been studying specific solutions. At present, their property has hired a professional appraisal agency to conduct unified inspection, and the specific construction needs further research. The property will publicize the final construction plan to the owner in combination with expert opinions, hoping to eliminate potential safety hazards and concerns of the owner. The author believes that even if the two broken pillars are not load-bearing pillars, since the pillars are broken, it will still bring danger to the people walking below. After all, the pillar is solid, and once it falls, it will still bring danger to pedestrians. Therefore, I still hope that the residential property will repair the two broken pillars and eliminate the concerns and security risks of all owners in the residential area.
