What are the possible causes of building collapse?

The simplest is to cut corners, and then there are many reasons, such as a long period of time due to serious weathering of the building, resulting in a decrease in the local solidity coefficient, serious corrosion, or a major natural disaster, like you said that the building is likely to be weathered.

A person who escaped from eating on the second floor said that the upstairs was being renovated, and the walls were vibrating, cracks, and cement were dropped, and then the hotel waiter saw that the situation was wrong and asked the customer to leave quickly, and it collapsed in a minute. . . It should be covered beyond the load-bearing, and then the upstairs decoration was drilled, which led to the accident!

The one who watched the tea took the tea and ate it. Guo Shuban said: "Mrs. Jin has always been in the house, when did you come to Jiangnan?"

Although it was 'really fake', he also lost a few taels of silver. I was bored at home, because Mr. Yun Si Xun was an old friend of Beijing, so I came to Yangzhou to see him, and I recommended him on the box and sent a few hundred taels of silver.

No.

In fact, the collapse of a house is not without warning, and the causes are usually inseparable from three aspects, the foundation, the construction and external forces". The ground sinks, cracks, bulges, cracks appear. load-bearing walls.

Cracks appeared, and they spread. The load-bearing column is deformed, either as a bulge or as an internal white mosquito.

Decay or decay. Part of the walls began to tilt, showing signs of collapse, the ceiling.

Begins to fall off in a large area without warning. There is a "weird" sound in the house, which comes from the inside of the house, similar to the "chirping sound", the sound of crackling. The collapse of the house is a very serious accident disaster, in addition to directly smashing people to death, it will also cause a series of other disasters, such as gas leakage, the occurrence of **, short circuit circuit, leading to ** disaster, and there will be traffic jams, these situations have increased the difficulty of rescue, once there are people trapped, then the rescue work will become very careful.

1. The signs before the collapse of the house are ground subsidence and hollowing.

Severe cracks or deformation in load-bearing columns, beams, slabs or walls; walls or ceilings.

Abscission; The abnormal noise of the house, as follows.

1. Pay attention to signs of the ground actually sagging, hollowing or cracks suddenly increasing.

2. Serious cracks appear in load-bearing columns, beams, slabs or walls, and continue to develop.

3. Excessive deformation of load-bearing columns, beams, slabs or walls, and serious decay of wooden components or connecting parts or white mosquitoes.

Decay. 4. The plastering layer of the wall or ceiling suddenly peels off and falls off in a large area.

5. The house suddenly emits abnormal sounds, such as "clapping sound", "chirping sound", popping sound, etc.

2. Common causes of house collapse.

1. The age of the house is too large.

The vast majority of residential buildings in China have been built in recent decades, especially after the reform of commercial housing, which has led to a boom in the real estate market. Theoretically, these houses are generally not very old, and the safety performance should be relatively good. However, in fact, due to the problems in the quality of raw materials, construction technology, construction level, quality control, etc., the actual service life of ordinary houses is generally short.

Some of the houses that were built earlier have gradually entered the period of scrapping and have become dilapidated houses.

2. Renovate the house at will.

Many house users are interested in the structure of the house.

Without full awareness, the house is remodeled at will. For example, many users have transformed their balconies into kitchens, stacking too many heavy objects on the balconies, destroying the original stability of the house, so there are many buildings that "drop off the balcony".

3. The foundation is not firm.

Geological exploration is generally an important part of housing construction, "high-rise buildings rise from the ground", if the foundation is not strong, the more likely the house will collapse. Taking Chenzhou as an example, the geological conditions of Chenzhou's underground are very complex and are typical karst landforms.

Underground caves, underground rivers.

There are a lot of undercurrents, and if the exploration is not in place, it is very easy to have various problems in foundation and piling.

Not only that, the depth, width and depth of the underground river, the thickness and integrity of the upper rock layer of the karst cave, the nature of the soil layer under the surface, the structure type, load size, length, width and height of the proposed building should also be considered in the exploration.

In the past, the houses where people lived were basically bungalows, so there was no need to consider some of the most dangerous factors, but the buildings were different, and the building would definitely feel better when they lived, but relatively speaking, there would also be some dangers, many elderly people were actually very concerned about these, in fact, it was a good thing to have a sense of crisis, after all, the situation could never be in their own hands, so what were the signs before the house collapsed? What should I pay attention to when a house collapses?

1. Pay attention to signs of the ground actually sagging, hollowing or cracks suddenly increasing.

2. Serious cracks appear in load-bearing columns, beams, slabs or walls, and continue to develop.

3. Excessive deformation of load-bearing columns, beams, slabs or walls, and serious decay or erosion of wood components or connecting parts have been eaten by white mosquitoes.

4. The plastering layer of the wall or ceiling suddenly peels off and falls off in a large area.

5. The house suddenly emits abnormal sounds, such as "clapping sound", "chirping sound", popping sound, etc.

What should I pay attention to when a house collapses?

1. Do not stay near the dangerous building in daily life, and should educate the children at home that they must not play near this kind of house, of course, if the building has been more obvious tilting, cracking, and ash loss, you should make a decision immediately, transfer decisively, and notify the neighbors to know, so as to stay away from danger at the last moment.

2. If the collapse of the building has occurred If the collapse has broken out, and it happens that you are in that building, you can use some utensils or hands to protect your head, drill under the table or evacuate the house, in the process, you must pay attention to protect your mouth and nose to prevent dust pollution, and if you are trapped inside, you can make a sound, shout, try to release light smoke and other signals to the outside for help.

3. Building collapse self-rescue In any case, if you really encounter the scene of house collapse, it is very important to master the self-rescue method, according to relevant professionals, when encountering the collapse of the building, we should pay attention to the above matters, one of which is to move the body carefully to prevent the larger debris from falling on oneself, the second is to protect the mouth and nose and place dust pollution, and the third is if there is just a water pipe and gas pipe next to the pillow, knock them to increase the awareness of rescuers.

What are the signs before a house collapses? What should I pay attention to when a house collapses? In the understanding of the problem, the comprehensiveness of the description is enough to let everyone have an understanding of some things, and the signs that appeared before the collapse of the house are easy to find.

First of all, there may be hollow drums or cracks before the collapse of the house, you can take a look at the ground at home, if the ground does have some subsidence, the house is likely to collapse. In addition, there are very serious cracks in the load-bearing wall or wall in the home, and there are cracks all the time, and the cracks are getting bigger and bigger, which indicates that the house may also collapse, and the load-bearing column of the house or the wall is relatively large deformation, and the decay of the connecting part may also lead to collapse, and there is a relatively abnormal sound in the house, and the wall or ceiling is peeling off or falling off in a large area.

There are signs that there will be collapses, bumps and cracks in front of the door. In the house, the doors and windows are in place, and cracks in the walls are occurring every day and the walls are tilted.

The signs of building collapse are as follows:

Omen 1:The ground suddenly sinks, hollow drums, or cracks suddenly increase.

Omen 2:Severe cracks in load-bearing columns, beams, slabs, or wallsand continue to grow.

Omen 3:Excessive deformation of load-bearing columns, beams, slabs, or walls, the wood components or joints are severely rotten or have been eaten by white mosquitoes.

Omen 4: The plastering layer of the wall or ceiling is suddenExtensive peeling and shedding

Omen 5:Suddenly, the house made an unusual sound, such as "clapping sound", "chirp", popping sound, etc.

Housing collapse incidents occur from time to time, so the living safety of houses has always been paid attention to, and the settlement of houses will also bring many hazards. There are many reasons for the settlement of houses, such as the construction meets the specifications during the initial construction, the materials are not up to standard, the geographical location is poor, the construction of adjacent buildings, etc., but no matter what the reason is, the harm caused by the settlement of the house to the house should not be underestimated, so let's take a look at the hazards of the settlement of the house!

1. Uniform settlement.

There are also two types of foundation settlement, namely uniform settlement and uneven settlement. As the name suggests, the house has a uniform settlement, and the four corners of the house will settle together, and over time the house will gradually sink into the ground.

2. Uneven settlement.

Uneven settlement of the house is the settlement of one side or corner of the house, which will cause the balance of the house to be broken, resulting in tilting. Once the house is tilted, it will also bring many problems, such as cracks in the wall, doors and windows can not be closed, etc., the uneven settlement of the house will generally not stop, and if left unchecked, it is very likely to collapse.

Once the house has settled, it must be entrusted to a professional foundation reinforcement company in time to deal with it, and if it is left unchecked for a long time, the harm is irreversible.

Building collapse is a very serious safety hazard, and building collapse is an omen, these early warning signs 1Sudden subsidence, hollowing, or sudden increase in cracks in the ground, 2Heavy-bearing columns or walls appear severe, cracked, and continue to develop, 3

or excessive deformation, eroded by termites, 4The walls, the ceiling plastering layer, suddenly peeled off in a large area, 5The house suddenly made a popping sound, and other unusual sounds.

The wall of a house collapsed, and the foundation of the adjacent Qingcheng Post Station was "suspended" - due north net.

When I passed by the Qingcheng Post Station 3 days ago, I found that the walls of a row of houses adjacent to the post station had collapsed and sunk into the ground, causing the entire Qingcheng Post Station to become suspended.

There are many reasons why a house can collapse, and here are some of the possible factors:

1.Natural disasters such as **, storms, floods, and landslides, etc.

2.Problems in the design of building structures, such as defective design and construction, lack of necessary bearing capacity, etc.

3.Wood durability using poor building materials or man-made destruction of materials.

4.The old configuration of the house is rounded or deviates from the maintenance for too long, such as not maintaining the roof or doors and windows frequently.

5.Foundation problems, such as an unstrong foundation or an uneven foundation.

6.Unreasonable use of the house, such as overloading, excessive oscillation or excessive vibration, etc.

7.Cavity disadvantages: temperature, or frequent operation of large equipment can also have an impact on the home.
