Is it good to build a house in the countryside with prefabricated panels for the roof? Any suggestio

In rural self-built houses, prefabricated slabs are used as roofs, especially 20 years ago, and the roof coverage was basically prefabricated cement slabs. Because the quality of this prefabricated cement is very low, and the speed of construction is relatively fast, basically the rural self-built houses can be hoisted in one day or half a day. But it also has disadvantages, that is, when doing waterproofing, the probability of rain leakage is relatively large.

In addition, prefabricated slabs cannot be used in areas with high frequency, because its seismic coefficient is too low and is easy to cause collapse. It is not impossible to use prefabricated floor slabs in rural self-built houses, and most of the factors that use this prefabricated floor slab are its cheapest, but it needs to accept its rain leakage and poor thermal insulation. And my suggestion is that it is not easy to build a house in the countryside, if it is not particularly poor, or use the cast-in-place cement poured roof, so that the roof is more rainproof, and the seismic coefficient is higher, and there is a very good thermal insulation effect.

Not bad, it must be paved with cement in advance, and then prefabricated panels. To buy a better one, it is best to buy it in a physical store.

In recent years, due to the improvement of living standards, many farmers have also increased their incomes, their lives have also improved, and they have begun to improve their home environment and prepare to build new houses. Nowadays, the quality of materials used to build houses is also very large, so that many farmers have a wider range of choices. In the past, prefabricated panels were used in many rural houses.

So is this kind of prefabricated panel really good? And now more people build houses using cast-in-place slabs, and this phenomenon of prefabricated slabs being replaced by cast-in-situ slabs shows that prefabricated slabs are not good? Why is that? Next, let's take a look. <>

1. What is a prefabricated board?

To put it simply, a prefabricated slab is an ordinary cement slab.

Its scientific name is prestressed concrete hollow slab is a spare building frame made by pre-fabrication process of building materials such as steel bar, cement, sand, and stone. At first, the prefabricated slabs were relatively cheap, so they were chosen by many rural house builders. Moreover, this kind of component does not have very high technical requirements, and can also shorten the construction period, and the completion speed is relatively fast.

Second, the disadvantages of prefabricated panels.

The prefabricated panels we mentioned above have so many benefits, which are both convenient and trouble-free, why have they been eliminated after the times? This is because most of the rural houses are a century-old plan, so they must be safe, and the prefabricated board is not a whole, its overall performance is not very good, and if it is in the area of the earth's plate activity, its seismic effect is also very poor, and its sound insulation effect is also very poor, so the prefabricated board is not suitable for use as a roof in the construction of rural houses. Secondly, now China has implemented homesteads for rural land.

, its building area has become smaller. Many rural friends have built high-rise buildings, and the prefabricated panels are the main components of the stairs, and if the stairs are built with prefabricated panels, there will be many potential safety hazards.

Due to the absence of structural safety performance. <>

If conditions permit, try to choose cast-in-place slabs for building houses in rural areas, which has a stronger overall structure and greater safety.

Rural people mostly use prefabricated panels when building houses, which have both disadvantages and advantages. However, there are more disadvantages than advantages, so this kind of board has also been eliminated. The first disadvantage is that it is particularly easy to cause roof leakage, which will not leak at the beginning, but after a few years, the prefabricated slab will crack, even if the asphalt is scraped, it will still be soaked in water, and then it will still crack.

The second disadvantage is that the structure of the prefabricated panels is not good, and the seismic resistance is particularly poor, which is not suitable for roofs. The third disadvantage is that the sound insulation effect is relatively poor, which will make you feel very uncomfortable while sleeping.

The prefabricated panels used for rural housing construction are not good, and there are many shortcomings.

In the past, prefabricated panels were very popular, and many rural people would use such panels as roofs when building houses. Because this kind of board is relatively easy to install, and ** relatively cheap, but after a few years of use, its shortcomings will be exposed. There are three disadvantages in total, which are rain leakage, poor seismic resistance, and poor sound insulation.

Why did it become the main board for rural housing construction in the past?

In fact, it can become the main roofing material for rural housing construction, because it is very cheap, after all, it is not easy for rural people to make money, and they can only make money by farming every year. When building a house, they want to build a larger house, so that it will be more decent, but they don't have the money to buy better building materials, so they will use prefabricated panels. So this is also a bit of a contradiction, in the beginning prefabricated panels are very good, but after a few years there will be all kinds of shortcomings, such as the house is shaky or the roof is leaking.

Summary. Fortunately, the construction technology is now better, and the various materials are also very advanced, which can be both practical and cost-effective. So now when rural people come to build houses, they will use other boards, and they will not buy prefabricated boards anymore.

Yes, it is not good, because there are no problems with the normal living of prefabricated slabs for decades, but there are big defects, the foundation of the house sinks downward, and there will be slab joints in the floor slabs.

Not good, because there is a high probability of collapse, especially in windy weather, it may be opened, and the safety factor is relatively low.

I don't think the prefabricated panels are really good, because the cost performance is not particularly high. There is also a possibility that there may be water leaks, so I think it is best to use waterproof sheets.

Prefabricated slabs can be used, but the quality of precast slabs is not as good as cast-in-place slabs, if there are conditions, cast-in-place slabs are still used, because cast-in-place slabs are not easy to deform, and the structure is more stable and safer.

You people have nothing to do, and you talk about the house every day! Large fields across the country are barren, why don't you go and solve it? Farmers are those who farm the fields, and they have bad intentions to discourage the enthusiasm of farmers!

The prefabricated slab is installed in a uniform size first, and then directly paved, which can speed up the construction and reduce costs, but its seismic resistance and impermeability are poor, so it should not be used in the kitchen and bathroom. The cast-in-place slab is directly poured with cement during construction, and its seismic resistance and anti-permeability are better than those of prefabricated slabs.

The cost of cast-in-place slabs is more expensive than prefabricated slabs. Although both have the function of separating floors and bearing gravity, cast-in-place slabs are stronger than prefabricated slabs in terms of bearing capacity, seismic resistance, sound insulation and waterproofing.

The prefabricated slab is more convenient to install, the construction speed is fast, and the cost is cheaper, but the shortcomings of the prefabricated slab are also very obvious, mainly because the seismic performance is not good, the integrity is poor, resulting in insufficient safety; Especially when ** comes, it is likely to fall as a whole, endangering personal safety, so seismic fortification areas are generally not allowed to be used.

The cast-in-place slab is different, it is composed of ring beams, floor slabs, columns and other whole cast-in-place reinforced concrete. Its integrity, durability, and seismic performance are significantly better. However, the construction process is also more complex, and professional workers are required to complete the formwork, steel bars, pouring concrete, and maintenance, so the cost is definitely more expensive than the prefabricated slab.

With the development of the times and building technology, people's living standards have also improved, and the requirements for housing quality have also been higher. As a result, a wide range of cast-in-place slabs slowly replaced prefabricated slabs. Let's take a look at the difference between prefabricated slabs and cast-in-place slabs.

1. In terms of structure, the integrity of the prefabricated slab is poor, while the commonly used cast-in-place slab is poured as a whole, seamlessly connected, and has good integrity.

2. It is convenient in construction, and the prefabricated board is easy to install as long as it is directly assembled. The cast-in-place construction is more complex and time-consuming than that of prefabricated slabs.

3. In terms of use, there may be gaps or water leakage in the prefabricated board, while the cast-in-place board is more stable and waterproof.

4. In terms of safety, cast-in-place slabs are definitely safer and more conducive to earthquake resistance.

Now the rural self-built, if the budget is not too tight, it is recommended to use cast-in-place slabs, and the performance of all aspects is guaranteed. Besides, hundreds of thousands of dollars have been spent on building houses, and you can't save on safety, right?

First of all, we need to understand, what is a prefabricated slab, prefabricated slab is simply a cement slab, his scientific name is prestressed concrete hollow slab, is a steel bar, cement, sand and gravel and other building materials through the pre-production process to complete the spare building components, and everyone chooses to use prefabricated slabs most of the reason is because of saving money, and the technical requirements are not high, can shorten the construction period, see here will definitely ask, why such a good building material will say, not good, in fact, This is due to the fact that rural housing construction is a century-old plan to focus on safety, but because the prefabricated board is not a whole, the overall performance is not good, which is naturally not conducive to the earthquake resistance of the house, and the sound insulation effect is relatively poor, so the prefabricated board is not suitable for the use of the roof in the construction of the house.

Because the prefabricated slab is already available, it can be put on the board when it is bought, and the working efficiency is high, and the construction speed of the project is faster. Because the prefabricated panel structure is a patchwork method, the gap in the middle is too large, the waterproofness is not very good, and the waterproof is not easy to seep. There are no production specifications, and they are all produced according to the original pattern.

Without specifications, the application cycle time of the prefabricated panels produced is not easy to be too long. This is also the fatal defect of prefabricated panels, and it is also the reason why prefabricated panels are gradually eliminated. In the case of a previously built house, if it is a double-storey house.

Most of the first floor is made of prefabricated panels, but in the process of building the house, in the process of settling down, we can experience the safety risks of prefabricated panels. Prefabricated panels are built after the house is built, after the interior is renovated. Most of them will have tiny gaps after a while, which will give people a more immediate security risk.

Although there have been no safety incidents in my hometown, it is more worrying. In particular, the safety risk is higher for rural people who produce it themselves. Rural self-built villas use prefabricated slab structure, the bigger disadvantage is that the comprehensiveness is very poor, even if the joints are poured with concrete structure, it will not take long for dry cracking to occur, which is also a key reason why prefabricated slabs are gradually eliminated.

However, for rural self-built villas with low stacked floors and very low seismic rating regulations, prefabricated panels can be applied.

Meticulously set up the fine stone pump and ring beam, and then lay prefabricated slabs on top of the ring beam or it may work. The roofs of rural houses are now available in both cast and prefabricated slabs, and only the foundation works are the most important....Regardless of the prefabricated components or precast concrete slabs used on the roof, there is an important technological process, which is to cover the overhead layer on the roof, and the relative height should not hit the head in the middle, and the overhead layer has four major advantages, first, sun protection isolation. Two.

Cold. Third, waterproof and rainproof, fourth, it can be used as a warehouse, and some production tools can be placed with dirt. The cost of the project is a little higher than that of waterproofing, but it is very cost-effective.

Prefabricated panels for rural housing construction are not good. Because there is nothing wrong with living normally for decades with prefabricated slabs, but there is a big defect in prefabricated slabs, once the foundation of the house sinks downward, slab joints will appear in the floor slabs. Moreover, the overall safety structure of the house is poor, and there is no shockproof effect at all.

It is not good, because this kind of plate is not strong at all, especially easy to be blown away by the wind, and there is no sense of security, it is easy to corrode, and the service life is not long.

It's particularly bad. Because such a board is not strong at all, and it is easy to be corroded by termites, it is particularly easy to break down in the later stage, and the service life is very short.

The process of making rubber sheets for self-built houses:

1. Make concrete in advance for later use.

2. Place the wooden board at the position where the rubber plate needs to be made to form a circle of templates.

3. Pave the steel mesh inside the formwork.

4. Pouring concrete.

5. Wait for the concrete to be solid and then remove the plank.

Rubber sheets are actually cast-in-place concrete. Cast-in-place is a reinforced concrete roof. Cast-in-place reinforced concrete has good self-waterproof performance, which means that the roof is not easy to leak, and after a long time, there is less water leakage in the event of heavy rainstorms and typhoons.

The seismic resistance of cast-in-place reinforced concrete roofs is relatively strong. In terms of flatness, cast-in-place reinforced concrete roofs are better than prefabricated roofs, and cast-in-place does not need plastering. Concrete cast-in-place slabs are poured in one go, while floor slabs are prefabricated in advance and assembled directly.

Prefabricated floor slabs are poured in advance and cost less than cast-in-place. Let me tell you about several problems that may arise when making prefabricated slabs on roofs: there will be seams in the splicing of prefabricated slabs, which need to be dealt with properly, otherwise there will be cracks and leaks.

If you use cast-in-situ, there will be no such problem, and now most of them will use the frame structure cast-in-place roof, because of its overall structure, so it is liked by many people.

In recent years, socio-economic development has been getting better and better. Even the rural economy has gradually developed and gradually shaken off the phenomenon of poverty and backwardness. Although many rural areas are not as wealthy as cities, their economic power should not be underestimated.

Many rural people make a lot of money and also have some savings. When the economic situation is good, many people first build a house for themselves. After all, housing is still very important.

Nowadays, most cities are commercial houses. They are ready-made houses that can be lived in as long as they are bought. But some people don't like it.

They like to build their own houses.

First of all, prefabricated slabs, as floor slabs commonly used in early construction, can be said to have gone through a building era. The construction is convenient, as long as it is directly assembled, it is easy to install. There is no stress in the center of the plate, so the center of the plate can be empty to reduce its own weight.

However, due to the widespread use process, some of the disadvantages of prefabricated slabs were also exposed: precast slabs were just hollow slabs with small bearing capacity, which was certainly not a good ceiling. In fact, some people are not suitable for using prefabricated panels on the stairs of their houses.

The structural performance is average, and the ** function is relatively weak, which weakens the escape function of the staircase. In contrast, the cost of cast-in-place slabs is much higher. The cast-in-place slab requires a large number of steel bars, and the technical requirements for construction personnel are also relatively high.

From the participation of the carpentry formwork to the pouring of concrete by the small workers, to the removal of the formwork, the cost of the workers is very high.

Although cast-in-place slabs can make the house structure more stable and of better quality, for rural areas with lower economic budgets, people prefer to choose prefabricated slabs. Therefore, if you want to save some money, you will still choose prefabricated panels, which can not only save cost and labor, but also economical and practical building materials. In addition to being lower than cast-in-place slabs, the technical requirements of prefabricated slabs are relatively low, which is in line with the actual situation of rural residential construction.

As long as it is not in the ** area, it is no problem to use it on the floor slab. Precast concrete also has some disadvantages, that is, when building a house with precast concrete floor slabs, the house is prone to cracks, resulting in water leakage, which affects the safety of the residence. When farmers choose to use prefabricated floor slabs when building their homes, they should also be aware of the drawbacks they may bring.

In any case, we have to weigh carefully when building a house. If the economic conditions allow, it is better for us to choose cast-in-place concrete floor slabs. After all, it's safer.
