What new building materials are there?
2. Hollow bricks: commonly used in non-load-bearing parts, the porosity is equal to or greater than 35%, and bricks with large empty size and small quantity are called hollow bricks. Hollow bricks are divided into cement hollow bricks, clay hollow bricks and shale hollow bricks. Hollow brick is the main wall material commonly used in construction industry. Because of its advantages of light weight and low consumption of raw materials, it has become the first choice recommended by the Ministry of Construction.
3. Aerated brick: autoclaved aerated concrete block, referred to as aerated brick, is produced by high-temperature autoclaved equipment technology. Aerated brick can be understood as a simplified or universal name. It should cover a wider range of products, that is, bricks produced by various other processes, including autoclaving.
Preparatory work before self-built houses in rural areas
1, construction drawings
In fact, building your own house is not as troublesome as you think, and the requirements for professional knowledge are not particularly high. Just pay attention to a few important places. Generally, before you start building a house, you must have a professional house design. Only you know the effect of the built house, so that the built house conforms to your own ideas, or you will be in trouble if you feel unattractive after building it.
2. Supervise the procurement of building materials
With house design, it is best to have a friend who knows this line to supervise the work, because in the process of building a house, the builder will inevitably be short of weight and cut corners, so it is very necessary to hire a supervisor! Of course, if you supervise the work yourself, you need to pay more attention. Then we began to prepare building materials, such as cement, sand, steel bars and so on. These are not bought casually. If you buy too much, retirement will be very troublesome. So you usually take the house design to the contractor of the construction team, and then the contractor will give you a rough estimate of how many building materials you need, and then he will make a list of materials, so that the materials you buy will not cause too much redundancy and waste.
3. Basic part
The most important part of building a house is foundation, because foundation is the support of the whole building. If there is a problem with the foundation, then the wall will be cracked because of the stress problem, which will be very troublesome and irreparable. When excavating the foundation, it is best to choose good weather. If it rains continuously, it is best not to start digging the foundation first, and then wait until the weather is fine. Because the foundation is a concealed project, before pouring the foundation, the supervisor must go to the site to check whether the reinforcement is consistent with the design of the house and whether the layer under the foundation is hard. Make sure there is no problem before pouring concrete.
4. Total building height
When building a house, we should pay attention to whether the overall height of the whole house is higher than that of the neighbors. I think this problem is a concern of most villagers in rural areas now, because if the height of a neighbor's house exceeds his own, it is not good from the perspective of geomantic omen. So when designing a house, you should make it clear to the designer. Don't design the height of the house too high, or it will cause dissatisfaction among neighbors. Under normal circumstances, a slight discrepancy is not a big problem, but it is still very troublesome for neighbors to be serious. Because this land belongs to the village, we should ensure the interests of our neighbors. If your house is built too high, it will definitely affect the surrounding neighbors in terms of lighting and ventilation, so they will make trouble when you build the house. Bian Xiao suggested that we should negotiate with our neighbors in a friendly way instead of going it alone, otherwise things will get worse and worse, which is not good for everyone.
5. Sign a construction contract
Finally, the most important thing is to have a building contract with the contractor at the beginning of building, so that the settlement can be well documented, otherwise it is not conducive to settlement, which is a mess and prone to contradictions. The construction team will do a good job of quality for you. Of course, they also want to make money, so they certainly don't want to let them lose.
