Unconsciously, a few hours passed, among them, Yang Yuanzhao called Qian Hu from time to time, on the one hand, is to fill in the drawings of this design by the number of their field measurements, on the other hand, but also from the field to ask them about their understanding of the steel structure, in the understanding, Yang Yuanzhao found that they seem to be unusually familiar with one of the steel structures, many steel structure indicators, without seeing the entity or drawings, they can say, and even draw inferences, In particular, Qian Hu often discusses and even argues with Yang Yuanzhao according to certain numbers.

Workers, even if they don't understand any big truths, in a certain aspect, after gradually becoming familiar with it, practice makes perfect, and some clever ones can summarize the rules from the middle, which is a good thing, and at least proves that they have spent a lot of thought in this aspect. For this reason, Yang Yuanzhao specially designed most of the scheme, directly overturned the change, replaced with the most familiar model of Qian Hu, this model is the most common steel model, the use of steel and connections a little more, and the entire steel structure requires a lot of work, but there is a point, the safety factor is high, Qian Hu they are relatively familiar, so the difficulty of construction, a certain degree of dù, will be reduced a lot.

Yang Yuanzhao is a mechanical engineer, very familiar with the three views and the like, the building is the part he is not very good at, but the steel structure, unlike ordinary buildings, does not need to consider what to share the pressure, or the relationship between the load-bearing wall, and it is not a high-rise building, just a maximum of 18 meters, 6 meters high, deconstruction of simple steel structure, with the rigor of mechanical engineers, plus the number calculated by the computer, finally, completed a first draft.

This first draft, has included the most important parts of the entire workshop, because it is the first time, he did not use the integral molding, but the whole steel structure is divided into different parts, in the part and part of the connected part, a large number of reinforcement, the difference between the steel structure and the ordinary structure is here, the steel structure can be set aside many parts, for the link between each other, the main focus point, just above these coarse steel, 15 cm long and wide steel, later generations can be used as load-bearing steel, In particular, special steel with relatively high strength is added to make an ordinary plant that does not bear too much weight, and there are not many problems at all.

Yang Yuanzhao carried out the preliminary design, completed the drawings, and asked Qian Hu to measure on the spot, draw out the model, and go back to weld it into a real steel model, a real steel model, with a scale about 20 times smaller to look directly at the structure, so that the number of steel bars consumed, only one-twentieth, but Rao is so, really made, the area of the entire model is almost 300 square meters, after the refinement, even some structures are omitted, and the steel used is more than 125 tons, It is enough for Yang Yuanzhao's production volume for more than a day.

It is this kind of seriousness, it took more than 2 days, the final design drawing was finalized, Qian Hu they took out the results of field measurements and models, Yang Yuanzhao compared the model to determine whether it can withstand it, completed the overall design, he needs at least 2 meters long, at least 15 centimeters long and wide steel bars, more than 5,000, including in the transfer, elbows, special components, is up to thousands, when this piece of 5,500 square meters, When the huge steel structure with a total area of more than 12,000 square meters is built, this piece will become the main factory area of the factory, as long as the steel structure is in place, at most a little more than a month, a huge building covering an area of 12,000 square meters will rise on the wasteland outside Baotou.

Such a huge steel structure, almost 2,500 tons, in later generations, may be just a factory, a day's production capacity, or even a day's production capacity may not be, but in this era, this is a difficult task to complete, especially in China, almost impossible, China does not have the ability to produce large quantities of steel.

At present, there is only a modern steel plant in China, Hanyang Iron Works, which is the result of the Westernization Movement, which took decades, but in the end, most of the production capacity can not be opened, even if it is in operation, the quality is not good, which can be very clear from the situation of the Yellow River railway bridge, it can already be very distinct, but it is a railway bridge with a load-bearing light train, but it can only be at a speed of 5 kilometers per hour, slowly dragged by a tractor one by one, in this case, how can it be possible to provide suitable steel, foreign imports, It is even more unlikely, not to mention the quality problem, the long traffic will make the cost surge to the point that it is unbearable.

Simply, Yang Yuanzhao did not plan to purchase, just right, during this time, there were not many production tasks, and some of the weapons that had been produced by Harpy were brought to Shanghai by Harpy for sale, supplementing the past few months, a large number of arms sales in Shanghai were vacant, and in the whole of China, arms are hard currency, so many foreign banks and compradors, 120,000 were consumed in a short time, and the market demand was not so strong.

The equipment for flour mills, brick and tile mills, and tractors have already been produced, and there are not too many tasks for the time being, and they can withstand full production, just bring them to produce these steel column structures.

Now the grade of the all-in-one machine is three-level, and these materials will not exceed the volume limit of the all-in-one machine, but the production of 4 tons per hour, even if the all-in-one machine goes all out, it will take close to 600 hours, that is, more than 20 days, which is not a short time.

Gave an order to the all-in-one machine, according to the drawings, the first production of raw materials configuration workshop, here will be placed two large grinders, crawler feeding belts, and some crane cranes and the like, the total area is about 700 square meters, a total of two floors, a total of 500 tons of various types of materials are needed, he needs to take three days to prepare, fortunately, in the initial stage of the steel structure, there is no need for steel, need to dig some foundations, and a few copies of some civil works, which Yang Yuanzhao through the coordination of Liu Shu, These blacksmiths and the original craftsmen of Baotou were brought together, and almost 50 strong laborers were recruited to temporarily form a steel construction company, which was the first project of the company, and for this, he even used the existing tractor chassis to make a simple tower crane.

Compared with the crane that is easy to move, the tower crane seems to be easier, of course, it is not the kind of later generations, the tower crane of the high-rise building, but it is a pure steel tower, there are two groups of steel arms distributed in the cross type, there are different hooks on it, and the simple movement of the pass guò can be determined to different positions, and then the steam engine below the guò urges the steel rope, pulls the steel bar, and reaches the predetermined position.

This kind of simple thing, in Yang Yuanzhao's view, is extremely backward, but unfortunately lifting this thing, is not his specialty, although he knows a little, in order to really make a qualified crane, it takes a long time to study, at this moment, he does not have this time, there are a lot of things, there is too much work, to solve this, I am afraid that after Harpy went to Europe and the United States, he recruited the first batch of scholars and engineers, so as to continue.

A simple tower crane, that is, more than a dozen tons of steel, a few hours to complete the production, Yang Yuanzhao called Qian Hu over, let him use the tractor, pull these things over, the tractor's tractor, is newly produced, the tractor is not only convenient when plowing, when pulling more materials, it is also quite convenient, especially the steel structure, don't look at a steel pipe that is not too long, the total weight will exceed 300 kilograms, once hundreds, it is 30 tons, such a weight, There are not many carriages that can be pulled, a carriage put on three or five, it is a little difficult, so it will be a great waste, steel tractor appeared, so that the horsepower of the tractor can be fully displayed, although, the trailer can only act on the smooth road, from Baotou here, to the outside of the industrial area, how far, the slow speed of the crawler tractor is acceptable.

40 tons of tower crane, divided into four different towers, as well as six interconnected measurements, steel rope at the top, can be driven by the rocker below, flexible in any position in the range of the tower crane, looks cumbersome, but let Qian Hu and others surprised, they think, huge, 12,000 square meters of steel house, all need them to carry the way on their shoulders, a more than 300 kilograms, two or three people, barely lifted up, just to a high place, not easy, But with this tower crane, many times, they can use machinery to save the body, so that not only safety, but also the speed of construction, will be greatly accelerated.

Looking at Qian Hu and others, working in full swing, Yang Yuanzhao did not stay here too much, and left quickly, today, coming from Taiyuan, the Yang family and the Wei family, recruited workers from all over the world, will arrive here, because of the problem of information, for these workers, Yang Yuanzhao is a wipe, must wait for them to arrive, will know, what kind of technical work they are, whether the cement plant can operate normally, how much cement can be produced, and how the output is, it all depends on a group of workers.
