Dong Chun was very satisfied with Li Zhongxin's explanation, after all, what Li Zhongxin said was in line with objective practical issues, and everything should be done in order, and it was even more important to understand the priorities.

Dong Chun can feel that the ambition of this faithful company is very big, otherwise, this company will definitely not give priority to any science and technology research and development building, this kind of thing Dong Chun has always felt that only the country will pay attention to this aspect, and the enterprise side only pays attention to interests and politics, and has no interest in scientific research at all, otherwise, the salary of the personnel engaged in scientific research will not be so low, and there is always a feeling of fear.

As for the residential buildings for the company's employees, Li Zhongxin said should only dig the foundation this year, and after laying the foundation, the official construction will begin next year.

Li Zhongxin said that in terms of housing conditions, experts and middle-level and above leaders of Zhongxin Company are preferred, those who have made outstanding contributions to Zhongxin Company are preferred, and experts hired by Zhongxin Company with high salaries are preferred.

The size of these houses is basically the same, and they are all spacious houses with a usable area of about 70 square meters.

There are many differences between the residence of Zhongxin company and the residence of other enterprises, at this time, the construction process is simple, and the materials are not sufficient, most of the employees' family buildings are two-story small buildings, and the five or six floors are the kind of tube buildings.

Most of the family houses that Li Zhongxin is preparing to build this time are new-style buildings with about six floors, and they are all the kind of pounded buildings with circle beams, with a maximum of eight floors.

At this time, when pouring concrete components in the construction industry, there is no mechanization, and each person takes a steel bar or wooden stick to pound the concrete, so that the concrete components reach a compact, which is called pounding.

At this time, the general buildings are not pounded, because the large construction machinery at this time is scarce, and the cement and steel materials are very expensive, they feel that the cost of pounding is too high, and the cost is too great.

The most important thing is that compared with the prefabricated building of the prefabricated building, the speed of the prefabricated building is quite fast, basically the frame is built, and the prefabricated board can be directly paved on it.

Concrete is made of a variety of materials, and if you do a few tons or dozens of tons at a time, it is estimated that it will not be uniform for half a day.

At this time, the faithful company is not bad for money, and it is not bad to buy all kinds of advanced machines, and the wealthy and wealthy faithful company will either not do it at this time, but if it does, it will be the best in this era.

Through the meeting with Wang Bo, Dong Zhiguo, and Yang Hua some time ago, Li Zhongxin also made a decision, although their company can't buy state-owned iron and steel enterprises now, but after hearing about the mayor of Qi City, they can place orders for state-owned iron and steel enterprises, and let those state-owned iron and steel enterprises produce the items they need.

Li Zhongxin thought that in later generations, the building was built with tower cranes, and at this time although China has such an advanced technology, but this kind of thing can only be purchased by large state-owned enterprises, he will let the steel mill produce the main components of the tower crane at this time, and he will use the shortest time to get out a large number of tower cranes belonging to the Zhongxin company.

Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane", with a section of the length (height) (referred to as "standard section"), used to lift construction steel bars, wooden flutes, concrete, steel pipes and other construction raw materials.

Tower cranes, also known as tower cranes, originated in Western Europe.

China's tower crane industry probably started in the fifties, from the perspective of tower crane technology development, the tower crane produced in China, in terms of efficiency, operation, maintenance and reliable operation are worse than developed countries.

Moreover, China for the tower crane technology some things are also slightly worse, this time of the tower crane, does not meet the kind Li Zhongxin wants, he told Wang Bo, and Qi City over there North Manchurian Special Steel when signing an agreement, try to place more orders, so that most of the components do the best, then he will find some professionals to study different nature of the tower crane.

Tower cranes with different technical performance characteristics to meet the specific needs of construction. Especially the kind of combined tower crane in later generations, after the completion of the construction of a building, it can be disassembled anytime and anywhere, and then reassembled, after the assembly is completed, there is no difference from the new tower crane.

Only when this kind of high-strength assembly tower crane is popularized, can the speed of China's construction be qualitatively leaped in the future.

Once the tower crane with independent technology is made out and can carry out a large number of production, there will be a large-scale acceleration when the country is building buildings.

Li Zhongxin talked to Wang Bo for a long time, but Wang Bo didn't understand what Li Zhongxin said about the use of these things, let alone understand, build a building, build a building, what kind of tower crane to build!

In Wang Bo's cognition, he had only seen a crane when installing electric poles and other things in Jiangcheng, and when the crane was installing electric poles, it gently used a wire rope to lift those heavy electric poles on the ground.

He remembers very well that in the first few years, the telephone poles were almost always wooden ones, and it took a dozen people to work together to put the poles into the dug earth pit.

By this time in '83 and '84, the telephone poles on the Jiangcheng side began to change into electric poles made of cement.

In the early years, the telephone poles that could be handled by employing people had to be lifted by cranes at this time to be able to put the telephone poles into the designated soil pits, and if they were to use manpower, twenty or thirty sturdy men could not do it.

All houses will be decorated with the best quality decoration materials, and the household appliances inside will be configured by the company, and when the time comes, you can settle in with your luggage.

In the 80s, not to mention a 70-square-meter fully decorated house, a house of 30 to 40 square meters was grabbed to break the head.

Who lives in first and who lives in later, often fights over these things. After all, the per capita living area at this time is too much different from the per capita living area of later generations.

Li Zhongxin's home is on the Jiangcheng side, which is basically quite good, but if it weren't for Li Zhongxin building a small second floor behind the original house, then the living area in his house would be more than 30 square meters, a big house with a fire kang, a small house with a small kang, and a small kitchen outside that can cook on the fire.
