How about light steel villa? Some views on the shortcomings of light steel residential buildings and their shortcomings

Life is like a play, and everyone is immersed in his role. Objective justice needs wisdom and strength. In recent years, the light steel villa was attacked by some people who sold civil drawings (later forced to enter this industry and began to sing praises for light steel. Specifically, we can carefully dig a grave for the currently hot house), and they have been attacked by civil engineers because they feel some kind of threat of being replaced. ...

At the beginning of the year, a post on the Internet caught my attention. What caught my attention was not his talk about the professionalism of light steel villas, but the strong feeling of indignation. Later, I dug a grave, and after half a year, I dug up his explanation for slapping myself. I found it very interesting, and now I will share it with you. The following is the person's self-report (brackets are supplemented by Hunan Xilaiju Technology Co., Ltd.):

Half a year ago, I wrote an article "How about light steel villa? In Zhihu, Baijiatou and other platforms, the book "Light-gauge steel houses have no shortcomings and light-gauge steel houses are insufficient" was published. It is used by traditional construction companies as a sword to convince builders who want to repair light steel villas, and it has also attracted the attention and comments of the majority of light steel villa lovers.

Today, we will discuss the topic of light steel villa again.

First of all, the previous article is indeed a factual statement at that time. Nowadays, some viewpoints in the article have changed.

First, the span is limited and the apartment is small.

Now the span is no longer limited, because in addition to heavy steel, thicker C/U steel can be used as a load-bearing beam, so the apartment can be large or small, and even can be used as an office building and so on.

Second, the wall is empty, like a board house.

Now some light steel companies combine EPS solid walls to enhance the thickness of houses; Even if we reuse rock wool/glass fiber wool, we can avoid the feeling of emptiness. First, the keel is no longer as hollow as before (the light steel keel here has never been hollow to the end, which belongs to the field of structural mechanics, so I guess this gentleman doesn't understand it very well), but there are several beams in the middle to divide the vacancy into several sections so that the filler won't fall off. Secondly, when the filler is compacted and sealed, more screws are usually used to fix the filler inside the wall.

Third, the construction is unprofessional and there are many hidden dangers.

Now many companies have relevant professional training and guidance, and the technology is becoming more and more advanced and practical. For example, outdoor waterproofing includes one layer of polypropylene coating, two layers of coating, three layers of asphalt waterproofing, followed by concrete tiles and multi-layer protection. This is especially true in bathrooms and kitchens, where concrete needs to be painted and solidified before waterproofing, so waterproofing is no longer a problem.

Fourth, elastic materials and flexible connections.

Now structural design will consider the problem of firmness. The same keel is fixed in many places, reinforced by upper and lower floors, and the wall is reinforced by cable-stayed belts. , are slowly but surely. In addition, the construction is strict with the workers, and the screws are not driven in, taken out and driven in again, and the screws are required to be free, loose and vacant, which enhances the integrity and stability of the house.

Fifth, the floor creaks occasionally.

At present, the floors of many light steel companies are made of thickened C/U-shaped steel, with corrugated steel bottom hanging steel wire mesh and concrete as the floors, and then tiles are attached to them if decorated. In this way, the problem of high floor area is solved, and the problem that the floor is easy to creak due to too many buildings is solved, so that the floor is thicker and stronger (in fact, the truss structure without corrugated plates can also avoid the problem of floor creaking, if there is any problem). There are so many people who have been here, and videos are flying all over the sky. At present, there are no related videos except text expression. It can be inferred that this is pure obscenity and the motive is self-evident. )

The sixth and other follow-up problems are human and commercial behaviors, and many performance disadvantages are not unique to light steel villas, but common to ordinary buildings. (This sentence is fair. There are various problems in brick-concrete structure, and various cracks abound. What kind of person, manufacturer and company you are looking for will naturally have different results. )

For example, maintenance costs will not be damaged by non-man-made damage, even if it is man-made knocking. Everything has a fixed number of years, and the house needs to be replaced when it is used for a certain number of years. Traditional buildings also hope to be replaced, which is not unique to light steel villas. Cars, furniture, household appliances, furniture, etc. Or should it be maintained, maintained, replaced and so on after a certain period of time. There is some truth in what is said here, but in fact, after the light steel villa is completed, it hardly needs maintenance. There is a light steel villa here in Changsha, Hunan Province, which has lived for 10 years. When we visited it, its present situation gave us great confidence.

For another example, agent joining is a social and commercial behavior. There are physical stores, online stores, WeChat merchants, direct selling companies and other channels or modes to buy toothpaste. It's just that different people have different views, so consumers can keep their eyes open and make rational choices. I only believe in a few points: a penny is worth a penny, and people don't know the goods; Buying is not as good as selling, and there will be no pie in the sky.

Conclusion: After reading it, I still appreciate this man. After all, he still has the courage to correct his mistakes. But as far as I know, there are still quite a few people with low cognitive level who continue to make rumors as a matter of course. Of course, it does not rule out that some irresponsible routine companies have used unreliable materials and built unreliable houses, causing public grievances. However, no matter what field you are in and what you are facing, it is a person's basic accomplishment to be awed by the unfamiliar and unfamiliar fields. I give you encouragement.
