Steel structure built on the second floor of the roomThe steps to build the second floor of the steel structure indoors were as follows:
1. ** Construction design and preparation **
- In terms of design, the layout of the steel structure had to be determined according to the size of the interior space, the bearing capacity, and other factors. Generally speaking, the steel structure of the main beam of the compartment was mostly made of I-beam and channel steel, and the secondary beam was made of square tube or angle steel. For steel with the same cross-section area, the bending strength of H-shaped steel, I-shaped steel, and U-shaped steel decreased in order.
- The construction team must be selected by a team with design and construction qualifications, because the reliability of the steel structure not only depended on the quality of the section steel, but also the bending resistance of the main beam. More importantly, it depended on the reasonable connection method between the steel structure and the wall.
2. ** Foundation Connection Construction **
- A combination of planting steel bars and slotting could be used. The groove should be no less than 10 cm deep and 10 mm wide, and the steel bars should be 15 cm deep into the wall to allow the concrete to bear the full force. The bond material used for planting the steel bars must be corrosion-resistant, anti-aging, and the bond strength must be far greater than the strength of the concrete. The curing speed must be fast, so that the implanted steel bars can bear the external force as soon as possible.
3. ** Steel structure construction **
- One method was to use steel that met the national standards to form a crisscrossed steel mesh. For example, the I-beam was the main beam, and the angle steel was the auxiliary beam, which was connected to the main beam. The division of the I-beam was determined according to the size of the pressure steel plate (floor tile, with different thickness of 0.8mm, 1.0mm, 1.2mm, etc.). During the lapping, the I-beam was allowed to bear half of the steel plate or more than the I-beam, so that the I-beam played a leading role in bearing. After the steel frame was connected, the pressed steel plates were floated and then were connected to the steel frame. The deformed steel grid was woven on the steel frame (according to the construction requirements of the concrete structure, the deformed steel bars with a diameter of 10mm and 12mm could be used, and the special binding wire for steel bar construction could be used to connect them). Finally, the light material was poured (such as ceramsite, and the ratio of cement: sand: ceramsite was 1:2:3).
- The other method was to place the pressed steel plate into the I-beam, and then to the auxiliary beam (the auxiliary beam was generally 80mm channel steel; when the steel frame had a large span and the main beam was separated, 120mm I-beam could be used as the auxiliary beam), so that it was level with the steel frame, and the steel grid was placed on the steel frame and steel plate for pouring. The difference between the two steel-concrete structure construction schemes was that the former was suitable for the situation where the total floor height was high enough, while the latter was used due to the height restriction. The height difference between the two was 100mm.
4. ** Follow-up Work **
- Wooden planks were laid on the steel structure, and flame-resistant plasterboard roofs could be hung below to form a partition. If it was a steel-concrete structure, it should be noted that its advantage was that it was soundproof and not easy to be deformed. The attic could be used as a toilet and had a good waterproof effect. The disadvantage was that it was heavier and the wall was more stressed. According to the calculation of this structure, the earthquake resistance coefficient was 8 degrees and the service life was more than 70 years.

The teacups are builtJianzhan was a specialty of Jianyang District, Nanping City, Fujian Province. It was a product of China's national geographical indication, specifically referring to the black glazed porcelain teacups in ancient kiln sites and the black glazed porcelain teacups in today's Jianyang area. It was a traditional Chinese porcelain, the main representative of black porcelain, one of the eight famous porcelains of the Song Dynasty, and enjoyed the reputation of "the pearl of the porcelain altar".
Jianzhan was created at the end of the Five Dynasties. It was popular during the Song Dynasty because of the tea competition. At that time, it was a tea set used by the royal family and was called "the only tea ware born for tea" by the tea industry. During the Yuan and Ming Dynasties, the tea drinking style declined due to the change. In modern times, as the country's cultural confidence increased, people began to like Jianzhan again. In the 1980s, the antique Jianzhan was successfully developed and revived.
The shape of the cup is simple, the shape is steady, the hand feels heavy, and the heat preservation and insulation are good. It can be divided into six types of glaze: rabbit hair, oil drop, partridges, black gold, bright change, and variegated glaze. From the shape, it can be divided into four types: open mouth, skimming mouth, converging mouth, and beam mouth. It also has a small number of high-foot cups, lamps, jars, bottles, etc.
The firing process of the cup was more complicated. For example, the glaze process. Although the glaze water was just a simple mixture of plant ash and ore, different proportions would make the firing result completely different. After the kiln was installed, the firing had to continue for two days and two nights without interruption, and the control of the fire after 1000 degrees was the most important thing to fire the best.
When choosing a Jianzhan, one could consider the place of origin, the maker, and so on. Jianyang was the place where Jianzhan was produced. The red soil of Shuiji here had an iron content of about 8%. This was an important source of Jianzhan's iron body, so one could choose a merchant based on the place of production. You could also choose the works of more famous masters in the Jianzhan circle, such as Sun Jianxing, Xu Jiayou, Li Da, etc. Master works usually had an inscription at the bottom, and some even had a collection certificate. These kinds of works were mostly handmade and more expensive. One could also choose a method similar to betting on luck. There were kiln betting modes on Taobao crowdfunding, Jingdong crowdfunding, Dongjia, Netease crowdfunding, and other platforms. They could participate at a lower price. Each biscuit had a serial number. If one was lucky, they could get a high-quality cup. If one was unlucky, they might be defective, but defective products would usually compensate for other construction cups. Most Jianzhan (unless the price was clearly stated, bargaining was not allowed) could be negotiated appropriately.

A temple built on a cliffThere are many temples built on cliffs in China, some of which are famous, including Xuankong Temple, Yungang Grottoes, the First Temple of the Yellow River on Mount Tai, and the Great Compassion Zen Temple of Putuo Sect on Mount Wutai. These temples attracted countless tourists with their unique architectural forms, traditional Buddhist culture, and magnificent natural landscape. Xuankong Temple was located in Hunyuan County, Datong City, Shanxi Province. It was built more than 1400 years ago during the Northern Wei Dynasty. Its main buildings were attached to the cliff. Yungang Grottoes was located in Yanggao County, Datong City, Shanxi Province. It was one of the treasure troves of Chinese grotto art. The Crouching Buddha Cave was one of the temples built on the cliff. The First Temple of the Yellow River on Mount Tai was located in Tai 'an City, Shandong Province. It was located on the cliff of Mount Tai and had a unique architectural style. Mount Wutai's Putuo Sect Cheng Dabei Temple was located in Wutai County, Xinzhou City, Shanxi Province. It was also a temple built on a cliff. The construction methods and supporting structures of these temples were unique, showing the wisdom and architectural skills of the ancients.
I built an empireI only know that you have established an empire, but I don't know what information you want to know about it. For example, do you want to know how to consolidate the rule of the empire, how to develop the economy, culture, or other related issues? Please provide a more specific question to answer.
Beauty cup builtThere was a type of cup known as the "Beauty Cup" in the cup. Jianzhan was a local traditional skill in Nanping City, Fujian Province, and was one of the national intangible cultural heritages. From some tests, some of the cups could be attracted by small magnets, but this was not an absolute method to judge the cup. It was also related to the iron content, the degree of reduction, the thickness of the cup wall, and so on. There were many Jianzhan artists who made all kinds of Jianzhan works. They had many achievements in different collections, appreciation, and craftsmanship evaluation. These achievements reflected the craftsmanship value of Jianzhan. However, the current reference materials did not give a detailed description of the uniqueness of the Beauty Cup Jianzhan in terms of craftsmanship and identification.

Can a spaceship be built?There were many videos that showed that spaceships could be built. For example, there was a video that taught him how to make the Millennium Falcon spaceship by hand, and there was also a video of a parent-child interaction digging for spaceship toys. In addition, there were also examples of spacecraft manufacturing in reality, such as Jeff Bezos announcing that he would take his own New Shepard spacecraft to space, and the United States 'boeing company working with others to develop an interplanetary passenger plane (although there were many problems during the test flight). China's Chang'e-6 also demonstrated advanced aerospace technology. All of these showed that spaceships could be built, and related videos could be from different angles such as the manufacturing process, test flight, or interesting interactions with spaceships.

Can a spaceship be built?A universe ship could be built.
In terms of design, engineers and scientists would draw sketches and create three-dimensional models based on mission objectives, such as exploring specific planets or performing space station resupply missions. They would consider the weight, size, material strength, and tolerance of the spacecraft in extreme environments.
During the structural and system integration phase, the propulsion system, life support system, communication system, and navigation system would be integrated. Each system would undergo rigorous testing to ensure reliability and safety. At the same time, lightweight and sturdy materials would be used to reduce weight, such as aluminum alloy and high-strength carbon fiber composite materials.
In the assembly and testing phase, all the components were transported to the clean room for assembly. The process was highly precise. After that, the spacecraft had to undergo a series of ground tests such as vibration tests, thermal vacuum tests, and a comprehensive inspection of the electrical system.
The fourth step was to refuel and prepare for launch. The spacecraft was transferred to the rocket for refuel. The safety standards for this process were extremely strict. After refilling, the technicians would do a final check on the system.
Finally, it was the launch and monitoring phase. After ignition, the spacecraft was sent into the Earth's atmosphere. During the flight, the ground control center closely monitored the status of the spacecraft and maintained contact with the astronauts. After the spacecraft reached the predetermined orbit, it carried out the mission and sent back data regularly. After the mission was over, it could return to Earth or become a scrapped satellite orbiting the Earth.
There were already actual spacecraft manufacturing cases. For example, the completion of the Ziwei Technology Spaceship Intelligent Manufacturing Base in the Liangxi Aerospace Industrial Park in Wuxi. This was the first commercial spacecraft intelligent manufacturing base in China, and it was expected to reach the mass production target of 10 spaceships per year.
