In Nanping or Gongbei, Zhuhai, where can I find a wooden model of the Eiffel Tower (Paris Tower)? I don't want a big one, but it's about medium, within 5 yuan.

The Eiffel Tower was designed by Gustave Eiffel, a French architect. In his early years, he was an expert on dry bridges. There are countless masterpieces in his life all over the world, but he is famous in the world with his name. In his own words: the Eiffel Tower "submerged me if my life was hers" construction. It turned out that although in Paris, the French government decided to build a big building to stand in the world, but the funds provided were only 1/5 of the cost. Eiffel Tower, in order to realize his design, his construction company and all his property were mortgaged to the bank as engineering investment.

A 1,-foot-tall building will lower the sky in Paris and suppress other landmarks in the city, such as Notre Dame, Louvre and Arc de Triomphe. ..... When the tower began to break ground, more than 3 famous Parisian citizens signed a petition to stop the project. They claimed that the Eiffel candlestick in Paris damaged its reputation and image. However, Eifel and the local government ignored the protests and the construction work continued to be affected.

On January 28th, 1887, the Eiffel Tower was officially launched. 25 workers work eight hours a day and 13 hours a day. In summer and winter, finally, on March 31, 1889, you are finished with the steel tower structure. The Eiffel Tower with more than 18, metal products weighs 7, tons, and 2,5, rivets with a total drilling of 7,, have been built. Because the front tower of each component is strictly numbered, a small mistake was made in the assembly. The construction is completely in accordance with the design, she? Without any changes, it can be seen that the design is reasonable, in terms of accuracy. According to statistics, there are more than 5,3 design sketches of the tower, of which 1,7 are full drawings.

Like all innovative buildings in Paris, the Eiffel Tower began, which is the most indifferent and rejected in Paris, not to mention the sharp criticism of those architectural and urban planning experts. Although the designer of the Eiffel Tower declared: "France is the only country in the world with its national flag hanging in the air 3 meters high, sometimes it can't convince people from all walks of life to oppose the tower.

Support for assembly began on July 1, 1887, and was completed 22 months later.

All the elements in Eiffel's factory are located in Levallois-Perret, a suburb of Paris. The 18, pieces used to construct the tower were specially designed and calculated, depicting the accuracy of one tenth of a millimeter, and then put together to form a new piece about five meters. Constructor, who worked on the great metal viaduct project, a team was responsible for 15 to 3 workers assembling this huge vertical set on site.

The construction of rivets for all metal parts of the tower and the improved method are held together at the completion time of the building.

rivet worker

First, the sheet is assembled in the factory using bolts, and a rivet is purchased and replaced by a rivet assembled with heat, which shrinks during the cooling process, thus ensuring a very tight fit.

four men in a team need to heat up each rivet assembly to keep it in that position, shape the head for the third time and beat it with a sledgehammer for the fourth time. Only one third of the 2,5, rivet towers are on the construction site? Insert directly.

each corner edge is placed on its own support block, and the pressure applied to it is 3 to 4 kilograms per square centimeter, and each block is bonded to the other wall. In buildings along the Seine River, builders use watertight metal caissons and inject compressed air to enable them to work below the water level.

The first level is achieved by using 12 temporary wooden brackets with a height of 3m and four larger brackets with a height of 4m each. "Sandbox" and hydraulic jack-use a permanent wedge after replacement-to locate the metal beam to the nearest millimeter.

on December 7, 1887, the main beam joined to the first level was completed.

The work was dragged by steam cranes, which climbed the tower by themselves, because they were used by runners who lifted along the tower.

There are many technical problems in the installation of public elevators, because there is no previous experience. When the elevator rises to such a height, such a load and the inclined track at different angles are further complicated.

in the east and west wharves (only on the first floor), the original machine of Lu Combaluzier Lepape, a French company, is provided, which adopts hydraulic driving double circulation chains and side guide rollers. Its poor performance led to its elimination. They were replaced by five-year-old Lille machinery in 1897 and 1899, relying on hydraulic accumulator, 16-meter-long main piston, cable ring and manual control. They succeeded in unswervingly promoting tourists to the second floor until the late 198s. Then, they were upgraded to meet today's regulations: old machines still provide heavy power as the weight of death, while modern high-pressure oil pumps and motors are driven by computer-controlled variable part loads.

The original elevator was used from Otis to the double-deck cabin on the second floor at the northern and southern terminals of the United States, and the hydraulic power cable was used. They were no rivals for the five-year-old Lille unit and the abandoned pillar from the south, respectively, shortly after 19 and the pillar from the north in 1912, after a failed attempt to reconnect the power supply to the electric motor. In the late 195s, more and more tourists installed large-capacity machinery in the North Wharf in 1965. Schneider Creusot Loire River and uses the best engineering and electrical machinery manufacturer, which was upgraded in 1995 with new cabin and computer control.

In 1983, the South Wharf was tampered with again. The small electric elevator was operated by Otis customer jules verne Restaurant. In 1989, a four-ton service elevator helped to alleviate the over-travel of the main elevator (Otis).
