Chapter 206 Patent Tool Man

Li Weidong was not in a hurry to find a second-hand inventor, because no one else could run away anyway.

After leaving the electric furnace factory, Li Weidong drove to the south gate and looked at the construction site of his new home.

For his new home, Li Weidong made a special trip to Tianjin University, found the teacher Xu who could speak Japanese, gave gifts such as tobacco, alcohol, sugar and tea, and asked Xu to help introduce a professor of architectural design.

Afterwards, Li Weidong directly gave the professor a design fee of 1,000 yuan, and asked the professor to help design a two-entry house.

The professor had never seen such a local tyrant. One thousand yuan was used to design a courtyard house. He happily accepted the money and gave Li Weidong a design drawing overnight.

For professors of architectural design, this one-story building is not the kind of venue with a large area, so there is no need to think about the problem of building structure. As for architectural acoustics, architectural optics, architectural thermal engineering, etc., there is no need to consider.

Li Weidong took the blueprints and went back to Qinghe. He went to the construction company to hire a construction team, demolished the original four houses, and started to build a house for himself.

In the middle and late 1980s, all units began to build family buildings, and the domestic construction industry entered a period of vigorous development. However, because the construction companies at that time were still state-run, and migrant workers were not popular, the number of construction workers was insufficient, and many units had to queue up to build buildings.

However, since prices began to skyrocket, construction companies have seen much less business, and many sites have even shut down. Mainly because the price of raw materials has increased, resulting in the cost exceeding the budget.

The construction industry is still very accurate in calculating costs. There is a special subject in architectural design called engineering estimation. That is to say, for a building, the cost of the building must be estimated at the beginning of the design.

The sudden increase in the price of this kind of raw material is also a very embarrassing thing in the construction industry. The price that had already been determined, saw that it was rising like climbing stairs every day, and no one could do the project steadfastly.

Fortunately, Li Weidong is a big dog. He has money in his hand. Even if he spends more than 10,000 yuan to buy raw materials, he doesn't care, as long as he can build the house solidly.

This house was built by Li Weidong for himself, and he would live there for more than 20 years, so Li Weidong was willing to spend money, so he simply used a steel-concrete structure and dug the bare foundation more than two meters deep.

For a building with only one floor, the steel-concrete structure and the foundation more than two meters deep are indeed a bit of a waste.

At that time, the self-built houses in the countryside were still made of adobe, and if they had a brick-concrete structure, they were considered luxury houses. And many of the buildings in the family homes of the units are also slab houses, in order to plan a low cost.

Needless to say the quality of adobe houses, even brick-concrete structures are not earthquake-resistant and have poor integrity; and slab houses are regarded as dilapidated houses in later generations.

Li Weidong's steel-concrete structure house is made of abundant materials. It is absolutely sturdy, and it is absolutely no problem to withstand a magnitude 9 earthquake.

In his previous life, Li Weidong personally participated in the construction of several factories, and he also worked with others on a small-scale real estate project, so he still has a little understanding of construction engineering.

It's just that the construction technology in the late 1980s was indeed much backward compared to later generations.

There is also a lack of modern construction equipment.

On the construction site of Li Weidong's house, there is not even a concrete mixer for construction. It is all up to the workers to use a shovel to mix the concrete manually.

This is the case in this era. Labor costs are cheap, and those who can use manpower absolutely do not need machinery. However, without machinery, the efficiency of construction is definitely much lower.

Looking at the construction progress, Li Weidong sighed helplessly: It seems that this new house cannot be completed before the Chinese New Year! If you want to live in the new house, it is estimated that it will happen in April or May next year.

After entering into December, the construction site must be stopped, and the construction will not continue until the next spring.

Because of the construction in the north, there is also a problem of construction in winter.

In winter, when the outdoor temperature is lower than 5 degrees Celsius, the construction will be affected, and when it is lower than 0 degrees Celsius, it will basically stop work.

When the temperature drops below 0 degrees Celsius, the moisture contained in soil, concrete, mortar, etc. freezes, and building materials are prone to brittle cracks. Therefore, construction projects such as site leveling, foundation treatment, and pouring concrete will be avoided as much as possible in winter.

In the future, the infrastructure madman has some methods of construction in winter, such as adding some antifreeze to the concrete, and then using various thermal insulation materials, even if it is minus five or six degrees, it will not delay the construction. A hospital can be built in ten days.

However, in the 1980s, there were no antifreeze and thermal insulation materials. Once the temperature dropped, the construction could only be continued when the flowers bloomed in the next spring.

...

On the weekend, Lu Jianli came to the electric furnace factory and proudly showed Li Weidong a sample of the toaster he made.

In order to test the effect of the toaster, Lu Jianli also went to the store to buy a piece of old bread, cut it into slices, and put it into the toaster.

I experimented many times and finally adjusted the temperature to the right temperature. For this temperature, I baked more than a dozen big white steamed buns, all of which were cheaper than the dog next door. Lu Jianli said.

Li Weidong looked at the old bread in Lu Jianli's hand, and smiled helplessly. What Westerners bake with toasters is not this traditional old bread. However, seeing Lu Jianli's enthusiastic look, Li Weidong did not correct him.

After a while, the smell of bread sounded, and when Lu Jianli pressed the button, the browned slices of bread bounced from the toaster.

Director Li, do you want to try it? It's hot, but it's delicious. Lu Jianli handed one piece of bread to Li Weidong.

Li Weidong was embarrassed to refute Lu Jianli's face, so he put a slice of bread in his mouth and took a bite, the heat was just right.

Director Li, how's it going, the toaster I made is not bad, right? Lu Jianli asked.

Mr. Lu, thank you for your hard work. I see that this toaster can be finalized. Li Weidong said.

Lu Jianli continued: Actually, there is still a problem with this toaster, but I can't solve this problem.

What's the problem? Li Weidong asked immediately.

The main problem is the heating rod. If the heating rod we use is used frequently, it will gradually deteriorate, and the heat provided by the new heating rod will not be as good as that of the new heating rod. That is to say, the same slice of bread, It needs more time to bake. Lu Jianli explained slowly.

Li Weidong nodded: This is a material problem, not something you and I can solve. When I produce here, as long as I don't cut corners, I have a clear conscience. By the way, the director of the horse factory told me before that you are right again. The furnace has been improved? Tell me about it.

I added a fire protection electronic protector, once the toaster catches fire, it will automatically cut off the power. Lu Jianli said.

This is a good thing, but it would be even better if there were more sirens, Li Weidong said.

The alarm sound can also be added, but it will cost money to install more electronic components. Lu Jianli said.

Spend some money, just spend some money! Teacher Lu, just buy whatever you need, and I'll reimburse you!

Li Weidong thought about it and felt that Lu Jianli, a poor teacher, should be cleaner in his pocket than his face, so he simply took out his wallet, counted 1,000 yuan, and handed it to Lu Jianli.

Mr. Lu, you can take this money first, and buy any parts you need. Li Weidong said.

How can an alarm be used so much! Lu Jianli repeatedly refused.

The rest will be used as gasoline money for motorcycles! Li Weidong forced the money into Lu Jianli's hands.

Lu Jianli hesitated for a while, but still collected the money.

Li Weidong then asked: Mr. Lu, why did you think of adding such a fire protection device to the cheese stove?

Mainly when I was doing experiments, I often couldn't control the temperature well, and I would burn the steamed buns, so I made such a protector, which is not complicated to make, and the gas stove I made before is safe. The protector is almost the same! Lu Jianli said.

Gas stove safety protector, this is a very practical thing. Li Weidong nodded.

I won the second prize in the National Five Little Wisdom Cup, and it is this gas stove safety protector. Lu Jianli said proudly.

Have you applied for a patent? Li Weidong asked immediately.

For the winners of the National Fifth Elementary Wisdom Cup, the organizers will help to apply for national patents, and they don't need to spend any money! Lu Jianli looked like he had taken a big advantage.

Li Weidong continued to ask: Mr. Lu, have you applied for an international patent for this gas stove safety protector?

I don't even have the money to apply for a national patent! I also apply for an international patent! Lu Jianli said.

Mr. Lu, do you want to apply for an international patent? Li Weidong asked.

I definitely think so, but I don't have the money. It should cost a lot of money to apply for a patent internationally, right? Lu Jianli answered honestly.

I know a patent operation company on Hong Kong Island. They specialize in patent operation business. If you want, I can ask them for help. Li Weidong paused, and then said: But if the patent is applied for, it must be Leave it to them to operate, and then they will have to take part of the commission.

Then let them do it! Just get me an international patent! Lu Jianli said without hesitation.

This percentage may be relatively high. Li Weidong continued.

I don't care! Anyway, I didn't make any money for the gas stove safety protector I invented. Lu Jianli continued: As long as you can get me an international patent, even if you don't give me money, I want that. Zhang International Patent Certificate! At that time, I have to frame it and hang it in the most conspicuous place in the house, what a face!

Li Weidong smiled slightly, it seems that this Lu Jianli is only seeking fame, not profit! Isn't this a patent tool man!

But it’s normal to think about it. Under the circumstances at that time, the domestic “Patent Law” was basically a decoration. The biggest benefit that a folk inventor like Lu Jianli got from invention patents was probably the certificate of merit of the National Five Little Wisdom Cups. .

Given the circumstances at the time, Lu Jianli did not expect to be able to profit from patents. For him, applying for an international patent was probably equivalent to winning an award at the National Five Little Wisdom Cup.

As for the PCT certification, it is similar to the certificate, but it is only used to show off in front of people!
