Qilu.com, September 26 News On September 26, the much-anticipated Shandong International Financial Center (IFC), the tallest building under construction in Shandong, ushered in the "double hundred meters", that is, the topping out of the 100-meter tower and the construction of the main tower Breaking through the 100-meter mark, the tallest height in Qilu appeared. The builders of the
project are using advanced construction concepts, superb construction skills and superb engineering quality to present a super high-rise boutique landmark building to Jinan, Quancheng, once again refreshing the Qilu skyline!
Shandong International Financial Center (IFC) is located at the intersection of Jinan Central Business District high-density comprehensive urban functional area and the landmark Central Park. It includes a main tower, a 100-meter tower, a podium and an underground garage. The construction area Covering an area of 409,000 square meters, the main tower is 428 meters tall, with 88 floors above ground and 4 floors underground. It is expected to be completed and put into use in 2021. After completion, it will become the tallest building in Shandong.
A number of "black technologies" helped "Yuugeer"
The project department took "striving for technological leadership and creating first-class quality" as the driving force. In the project construction, it used a variety of new construction technologies used for the first time in Shandong Province to help "Shandong's No. 1 "One high" keeps "jumping up".
"dragon absorbs water" - large volume concrete rapid pouring technology. In order to quickly optimize the "dragon water absorption" - large-volume concrete rapid pouring technology. In order to complete the concrete pouring of the foundation floor with a maximum thickness of 12.1m quickly and with high quality, the project department used five concrete mixing stations and deployed 110 concrete mixer trucks to deliver materials together. The "chute + concrete conveyor + truck pump" pouring method was adopted. The on-site layout Four large chutes were built, like four giant dragons hovering over the construction site, with an average speed of 370m³ and a maximum speed of 670m³. In the end, it only took 56 hours to complete the 4,100-square-meter tower foundation floor and 21,000 cubic meters of concrete pouring, refreshing It has set a number of indicators for large-volume concrete pouring, breaking and surpassing the historical record of single pouring in Jinan City, and opening a new chapter in large-volume concrete pouring.
"Tongtian Lux" - attached self-climbing luffing jib tower crane external construction technology. This is a new technology independently developed and applied by the project department for the first time, taking into account many factors such as lifting weight, lifting times, and distribution characteristics of the steel structure. Its maximum working range is 55 meters and its maximum lifting capacity is 80 tons. It can meet the lifting tasks safely and efficiently, providing guarantee for the rapid and high-quality construction of the project's civil engineering and steel structures.
"Tower Building Artifact" - low-position, few-fulcrum intelligent hydraulic jacking platform technology, also known as "intelligent building machine". This is also the first time this technology has been used in Shandong Province, solving the technical problems in the construction of the vertical structure of the tower core tube in one fell swoop , quality, safety, fire protection, environmental protection, energy saving and other problems. The project department has also improved and optimized the installation process, and innovatively applied modular overall installation technology. The truss modules are assembled and welded on the ground at one time. With the help of a luffing tower crane, the modules are lifted in the air and connected in the air. Taking full advantage of the advantages of safe and stable ground operations, fast operation speed, and high installation accuracy, it not only shortened the installation period of the entire truss by nearly 30%, but also reduced the risks of high-altitude operations, taking into account quality, safety, and green construction. and other various needs.
In addition, the use of the HBT90-CH ultra-high pressure concrete delivery pump ensures the synchronous climbing between the construction elevator and the top formwork system, providing construction workers with vertical transportation. Its maximum conveying height can reach 580 meters. The core tube is equipped with two HGY21 placing machines fixed on the top form truss and lifted together with the steel platform. It can rotate 360 degrees. The discharge port is connected to the string barrel for concrete pouring. There are 7 medium-high-speed variable frequency construction elevators inside and outside the core tube, equipped with 13 ladder cages, which are divided into high and low zones. The elevator operates through a specially designed attachment system, which uses a rolling attachment wall to connect to the jacking platform, allowing direct access to the top mold working platform. "The highest in Shandong" is also the "first in intelligence". Smart construction sites are an inevitable trend in the development of informatization in the construction industry. In order to ensure the efficiency, energy saving, environmental protection and harmony of project construction, the construction side strives to promote the modernization of smart construction and will "Shandong's No. 1 "One High" has become "The First High in Wisdom".
