In order to protect innovations that are beneficial to social development, Huaxia has also added some provisions similar to the patent law to the law with reference to real-world methods.

Such protection measures greatly stimulate the creativity of those workers who have ideas.

In the construction of the underground part of the urban unit, a large number of steel connection processes are used.

In the real world, there are three commonly used reinforcement connection methods for reinforced concrete construction, namely the lashing method, the electric welding method and the mechanical joint method.

The binding method is simple in construction, high in efficiency, and does not damage the steel bar, but its disadvantage is that the steel bar is wasted too much, and the skeleton is easy to deform.

The advantages of the electric welding method are that the steel frame is firm, not easy to deform, and the steel bar is saved, and the disadvantage is that the steel bar is damaged and energy is consumed.

The advantages of the mechanical joint method are that it does not harm the steel bar, the degree of specialization is high (standardized), and the operation is simple, but the disadvantages are troublesome process, inconvenient installation, and energy consumption.

Judging from the test of the three joint methods, the joint strength of the mechanical joint method is high, the same strength as the base metal, and the connection quality is stable and reliable.

For some steel bars with larger diameters, the ordinary binding method is not applicable, and the electric welding method has higher requirements for the welder's individual welding technology and welding equipment.

Most of the mechanical joint methods are extrusion and spiral, both of which require specialized interface processing tools, and the joining process is not as simple as it seems.

In the era of the great integration of various positions and knowledge in Huaxia, the carpenter suggested the use of mortise and tenon structure to connect the steel joints.

The traditional tenon and tenon structure can be quickly connected without obvious connection points on the surface under the condition of ensuring the strength of the joint.

However, the processing of steel bars is not as easy as that of wood, so only wedge tenons with relatively simple joints can be used.

Moreover, in order to further enhance the connection strength of the rebar joint, the carpenter and rebar worker conducted a more in-depth discussion.

Using wooden sticks as the test material, they experimented with hundreds of different tenon styles depending on the characteristics of the rebar.

Eventually, they determined a tenon style that would facilitate steel processing based on how the rebar material was processed.

The rebar joints are machined into two tenons that fit together, and a sleeve is sleeved on the outside.

However, there is no wire in this sleeve, but the joint and the sleeve are locked by wedges.

Since there is no need to rotate or extrude with a special extrusion machine, the connection is fixed for a shorter time and is more efficient.

More conveniently, only the wedge needs to be removed, and the connection of the sleeve and the joint can be separated.

After determining the final wedge connection, they released another task on the platform and paid a certain amount of Huaxia coins.

In the case that the task platform has already covered all workers in Huaxia, the task platform will automatically push task invitation information to members with relevant technical capabilities according to the requirements and categories selected when publishing tasks.

With the support of such a convenient way of human resource allocation, the top technical talents in the field of blacksmiths and machining in Huaxia directly and quickly participated in the research on how to design and manufacture a simple and convenient steel bar and tenon processing equipment by accepting tasks.

Such an efficient way of allocating human and social resources cannot be achieved by the social operation model in the real world.

At the very least, the ideas of a large number of people at the bottom will not be supported by relevant technical forces if they do not have strong connections.

This leads to a lot of fantastic ideas, but in the end they are not translated into real productivity.

Even whether some of their ideas are possible to be realized under the existing technical conditions are not guided by professional and technical personnel, let alone how to improve them scientifically.

The new steel bar connection equipment was quickly applied to the construction site of Huaxia Kingdom, which saved a lot of working time under the condition of ensuring the quality of the connection, and was well received by the steel bar workers.

But the wisdom of the laborers is infinite, and perhaps, they only need that one percent of inspiration to have a profound impact on the development of something.

One of the reinforcing steelers, when using this joining equipment, found that the tenon and tenon connection of reinforcing steel did not need to consider the appearance of the joints as in the case of furniture.

Because after they are wrapped in concrete, their only function is to exert their maximum pulling force, and it doesn't matter if the joints are good or not.

Therefore, the reinforcing steel worker has improved the connection using the tenon structure again, widening the sleeve so that it can easily be placed in two rebar side by side.

Then make a small opening in the middle of this oval sleeve and insert an iron wedge between the two steel bars to make it tightly bound to the sleeve.

Such a design not only incorporates the technology of extrusion connection, but does not reduce the strength of the sleeve.

The biggest change is the application of a mortise and tenon structure without the need for pre-machining of the shape of the joint.

In this way, it can even be used without professional tools, with just a hammer.

In the case of a special wedge pressing tool, the efficiency is again a notch higher than the kind of connection previously invented by the carpenter, and there is almost no limitation of the operating space.

In this way, the new joining tools jointly invented by carpenters and reinforcing steelers have not sold much, and they have lost their market because of the emergence of more convenient tools.

The large amount of investment in the early stage did not get enough returns, so the carpenter fed back the matter to the online platform, hoping that the Ministry of State-owned Assets Supervision and Administration would protect their inventions in accordance with relevant laws and regulations to safeguard their legitimate rights and interests.

This is the first case involving patents since the establishment of Huaxia State.

For such a thing, the members of Huaxia also had a heated discussion through the online platform.

"I think the way the carpenter invented the way of joining, and the way it generates profit is by selling the joint processing machinery and that simple sleeve.

In the latter modified way of joining, the tools used are not fundamentally related to the tools invented by the carpenter, and are completely different things, so the carpenter should not be paid royalties. ”

"Since Huaxia has enacted a patent law, it should protect the invention of wedge-jointed steel bars invented by carpenters.

Before the invention of the wedge connection method, the lashing method was still used in most places.

Carpenters transplanted some of the processing methods of their industry to the joining process of steel bars, which improved the efficiency of steel bar connections, and created a precedent for wedge connections.

Although the later improved connection method is simpler and more effective, it is difficult to directly translate into a product without being inspired by the wedge connection method.

Therefore, I think that the profits generated by the later improved connection methods should be paid to the carpenter a certain royalty. ”

"I don't think there's a direct correlation between the two approaches, and both are more efficient than the previous ones.

However, the later improved connection method completely upgraded the connection process of the steel bar to a higher level, but this connection method does not necessarily have to use the corresponding tools except for the improved sleeve.

Therefore, it is unrealistic to expect to generate much profit and pay royalties for other patents just by making a simple sleeve. ”
