At the end of the year, good news came from the curtain wall branch of the China Building Decoration Association. The China State Construction Enterprise Building project undertaken by the China Construction Seventh Bureau Construction Company won the 2019 "China Building Curtain Wall Excellent Project Award", becoming the only Henan Province to receive the award Engineering. In addition, the external curtain wall engineering, public building decoration engineering and public building decoration design of the project previously won the China Building Decoration Engineering Award, marking that a project of the construction company has won 4 "national excellence" awards, and written for the company’s annual excellence A strong stroke was made.
Peng Zhen, the chief engineer of the Curtain Wall Division of the China Construction Seventh Bureau Construction Company and the project manager of the China Construction Enterprise Building Project Manager, said with emotion: "Our goal is to pursue perfection. Although the construction process is very difficult, we have won 4 "national excellence". The result was very sweet. Our project team of more than 40 people and more than 900 workers finally got a great value in return."
The difficulty is beyond imagination, bravely meet the challenge
As a landmark building in the Economic Development Zone of Zhengzhou City, Henan Province, the design of China State Construction Enterprise Building is unique. Outer divergence, symbolizing the rise of a new city. The design of the façade adopts flowing water as the image, and the scattered vertical rods resemble a waterfall pouring down, which is novel and beautiful.
The project is located at the southeast corner of the intersection of Jingkai 15th Avenue and Jingnanba Road in Zhengzhou City. It has a total land area of 50,800 square meters and a total construction area of 172,000 square meters. The overall layout consists of four main buildings A, B, C, and D + It is composed of a circular podium and a corridor, which is a comprehensive commercial office building. The contract cost of the curtain wall project is 72,911,400 yuan.
Zhang Wentao, manager of the curtain wall business department, said: “The four buildings of the project are all curved, and it is difficult to place the lines; the aluminum decorative strips between the floors are all special-shaped panels, up to 7756 pieces; the largest glass of the main building weighs 145.8 kilograms. There are 3228 pieces in total. There are 89 kinds of materials used for exterior decoration; there are many intersections of different materials and different types of curtain walls, and the difficulty of construction is beyond imagination."
In view of the difficulty of construction technology, the curtain wall division appointed chief engineer Peng Zhen as the project manager, and appointed Cui Yongde with rich construction experience as the production manager, and Yuan Nannan with strong technical level as the chief engineer. Since October 2008, Peng Zhen has been fighting on the front line of the project. The four decoration projects of Zhoukou Citizen Service Center and Zhoukou Merchants Building where he is the project manager have all successfully created national excellence. With outstanding performance, Peng Zhen was promoted to chief engineer of the business department in February 2017. Zhang Liwei, chief engineer of the construction company, said: "Peng Zhenlai is the project manager of the China State Construction Enterprise Building. As far as the construction company is concerned, it is not only an entrusted task, but also a welcome."
Peng Zhen said: "This is the most difficult project I have encountered in my 10-year career. Only with difficulty, courage, confidence, and responsibility are needed to go all out to complete the tasks assigned by the organization."
Precision comes from being careful and not afraid of hard work
At the beginning of the curtain wall project in September 2017, the project department locked the goal of creating excellence, actively carried out excellent innovation planning, and invited national and provincial experts to teach 5 times on the project. The project department organized the main engineering and technical management personnel to observe and observe a number of national quality projects in Zhengzhou, Luoyang and Puyang, understand the process of excellence, and learn detailed practices. On this basis, they compiled and gradually improved a detailed plan for excellence.
Buildings A and B of China Construction Venture Building are both 18 floors, sharing a long lobby, which is a major difficulty in decoration construction. According to the structural requirements, there are 16 giant columns and square columns distributed in the lobby. The columns are made of golden stainless steel. Each composite stainless steel plate is 4 meters high. It has high brightness and high precision, and no flaws are allowed. In order to select manufacturers that meet the production conditions, Peng Zhen led project managers to more than 10 factories in Guangdong, Fujian and other places to inspect their production capacity on site, compare their samples one by one, and finally selected a scale in Foshan, Guangdong. Large factories with strong production capacity act as partners.
In June 2018, when the first stainless steel square column sample was produced, Peng Zhen and the on-site engineer from the construction unit rushed to the factory in Foshan, Guangdong, and pulled apart the stainless steel plate sample with the original design of 2 cm honeycomb thickness, and carefully observed and studied. , And simulated the installation on site. It was found that the honeycomb thickness was not enough and the flatness of the installation could not meet the requirements. Therefore, after recalculating and experimenting, the honeycomb thickness of the steel plate must be 2.6 cm for the best flatness. Therefore, the factory started mass production according to the new honeycomb thickness.
In order to ensure the successful installation of the stainless steel plates of the cylindrical and square columns at one time, Peng Zhen and the on-site engineer went to Foshan, Guangdong, and carefully checked and accepted all the products produced by the factory. They did not miss any minor details and agreed to send them after confirming that there were no defects. goods.
The stone of the lobby curtain wall is all irregular shaped stones. 940 stones of more than 400 square meters are selected one by one from the stone factory in Shuitou, Fujian, and delivered to the project site.
Cui Yongde said: “Stone is very fragile and precious. From processing, transportation to installation, we put protective covers on the corners of each stone, and carefully protect the finished product to ensure that no damage is caused. When installing, the management personnel will implement Under the supervision of the station, the workers are careful, handle and handle with care, and work with meticulous craftsmanship. The stone and the stone are closely intertwined, and there is no difference between them. All stone installations are zero broken, creating a miracle in stone construction."
The scale grasps the precision and the details are almost perfect
The decoration of the multifunctional lecture hall on the fourth floor is another major difficulty in the project construction. The multifunctional hall covers an area of more than 700 square meters, and the top is a hyperboloid laminated special-shaped aluminum plate, and it is tightly seamed, so it can't be installed if it is slightly offset. To this end, the project department closely relied on the company's mature BIM technology to place orders, and joined forces with the domestic first-class Shanghai Aluminum Sheet Company to process 200 special-shaped aluminum sheets of different sizes. The project management personnel supervised on-site, the workers accurately calculated, meticulously typeset, and accurately installed, and the installation was in place at one time without any loss.
During the construction of the 16th and 17th floor long corridors and their ceilings, it was the hottest season of the year. Cui Yongde and Yuan Nannan led the management staff to watch the scene and arrived at their posts at 6 o'clock in the morning, sweating with the workers. Busy, pay special attention to the connection between the wooden floor on the ground and the outdoor corridor carpet, the closing of the wall and the ceiling, to achieve natural and stable joints, uniform ground, and flat ceiling without error.
Yuan Nannan said: "We are not only striving for perfection in the difficult construction, but also in the construction of the standard level, we also strictly implement the quality management system rules, strictly control the process, and achieve planning first, technical clarification, precise line-out, model first and last Field tracking, strict requirements for each process to be higher than the national technical standards to ensure that the first time is excellent."
During the construction process, the project team paid great attention to summary and refinement. It not only published 6 papers in newspapers and magazines above the provincial level, but also published 4 provincial QC results, successfully declared 1 national invention patent, 5 utility model patents, and created construction methods. 2 items.
The review uation by the review expert group of the China Building Decoration Engineering Award is that “the surface of the facade of China State Construction Enterprise Building is beautiful and smooth, the glue joints of the curtain wall are straight and run through; the horizontal decorative components are beautiful in lines and the installation is firm; the arc glass is round and round. Smooth, with perfect color matching of the glass and decorative strips; the entire glass curtain wall in the lobby is straight, transparent and bright. The quality of the process is properly controlled, and all details and measured data have reached the excellent standards of similar projects."
According to reports, at the end of 2019, the project stood out among nearly 400 China Building Decoration Engineering Award projects nationwide, and won the "China Building Curtain Wall Excellent Engineering Award" in one fell swoop. Today, China State Construction Enterprise Building, a chic and beautifully decorated central enterprise ingenuity, has become a gorgeous scenery in the southeast of Zhengzhou City, showing endless charm.
