Collaborate Lego and build houses | Research on the depth of precast housing
At the time of the National Day, I bought a gift for my child, a gift box with up to 500 pieces of building blocks for racing cars.
All the modules have their own uses.
There should be no error.
I also went to investigate and study the base of this enterprise in depth some time ago.
All the building blocks are produced with precision, and the error is not more than 1mm.
For example, your balcony, window and staircase have become parts of the factory.
To make a pencil in Germany, it needed cedar wood from California, graphite from Heilongjiang, China, rubber from Jalala, Thailand…
To produce a wooden rod, it needed to saw a tree, and to saw a tree, it needed steel, If you want to have steel, you must make steel, if you want to make steel, you must mine, if you want miners, you must eat.
What is the difference between precast housing and traditional housing? In short, the construction of traditional houses has given birth to the construction industry.
Each floor, column and other structural members are penetrated with steel bars, and the building structure is very solid.
Lao Hu didn’t have time to accompany Wang Shi to see it by himself, so he flew to the assembly enterprise base of Jianye to investigate.
In fact, precast housing has matured in foreign countries for a long time.
In addition, you will find that the blocks modularize all parts and steps, which is indeed more efficient.
● ● ● 3 ● ● ● What are the advantages of precast housing? First of all, it is a guarantee of quality for buyers.
There is a refill in a wooden pole, and a rubber is fixed on a metal ring.
When the house is built, they can be directly hung up and spliced.
The enterprise that Jianye acquired is called Zhuyou Zhizao.
To make a pencil, different people need to cooperate in production, which is the industrialization of manufacturing industry.
This base is really like a factory, with production lines producing precast parts – parts needed for building houses.
First of all, the raw materials of pencils are too complex for us to imagine.
It is a house built by prefabricating some or all components of the house in the factory and then transporting them to the construction site.
In the traditional project of building houses, many people will find that the wall is not completely vertical to the ground in the end, because the on-site pouring construction will always produce greater errors.
China has also been trying to catch up in the past decade, and Shanghai has also achieved full assembly in 2016.
You must splice them together according to their functions without error to make them look like you want.
Because precast stairs and exterior walls are transported to the construction site, they also need to be overlapped with reinforced concrete, not simply connected.
Wang Shi has always been committed to the industrialization of housing in Vanke.
They only need to be installed on the construction site.
The plastering process is canceled because of the integrated molding in advance, which greatly reduces the common quality problems of traditional construction, such as leakage, hollowing, reinforcement leakage and pockmarks, and even the structure itself will be waterproof.
.
● ● 1 ● ● ● Which is more difficult to build a pencil or a house? Don’t worry about telling the answer first.
When I opened it, I was very nervous: How should I put together so many building blocks, and how long can I put them together? Is there any error? Later, I found that I was worried about all these things.
This paint is made of mixed castor oil; Look at the metal ring on the top of the pencil, which is made of alloy; And the milky rubber, which is said to be polyethylene based, is made of rubber or plastic, sulfur, vegetable oil and crushed stone; The graphite in the refill should be added with clay and paraffin.
Japan began to implement precast housing as early as 1973, and the United States has realized industrialization for a long time.
● ● 2 ● ● If you find that the construction industry has been overturned by industrialization, all the walls, stairs, balconies, and beams of your house have been put together like Lego blocks, is it interesting? According to friends in the industry, Hu Baosen of Jianye was very excited to tell Wang Shi that he had bought a listed company that made precast housing.
The components are like building blocks, but assembled by more reliable connection methods.
There was once a documentary film “The Birth of a Pencil”.
Wang Shi was more excited than Lao Hu.
Because visionaries like Wang Shi and Lao Hu can clearly see that the current level of construction technology is still very backward, and the cost of industrialization is still relatively high, but the housing industrialization is the inevitable trend in the future.
Concrete is formed on the mechanized equipment through industrial production processes such as vibration, professional curing kiln maintenance, etc., with higher component accuracy, better flatness and rigidity.
That’s all.
But in fact, it is far from that.
The precast housing can be produced in the factory and installed on the site.
After his retirement from Vanke, he also took a great job in housing industrialization.
Its manufacturing process was also very complex, and it needed very precise instruments to process it: it needed thousands of people to work together to produce a pencil.
However, the precast building is designed in depth through the BIM technology (BIM is the building information model, which can be written in another article), and then precast parts are produced in the factory assembly line.
But the more important test is the accuracy.
The pencil looks simple.
Even the floor slabs, columns and beams have been cast in the factory in advance.
First of all, what is precast housing? Why is Wang Shi so excited? In fact, precast houses can be fully understood as precast houses, which are built by industrial production methods.
They should be integrated in advance.
For example, you may also find that the wood of all pencils is the same, because the pencil holder is made of cedar wood; The paint on the pencil is not one layer, but six layers.
All the construction of traditional houses must be completed on the construction site.
When you and your child splice a pile of scattered blocks into a remote control car, you have a sense of achievement.
It can maximize the improvement of wall cracks, leakage and other common quality problems, and improve the overall safety level, fire resistance and durability of the residence.
