Description

Technical Field

[0001] The present invention belongs to the field of concrete placing machine construction, and in particular relates to a building construction platform with a vertical machine position and a concrete placing machine system and a construction method. Background Art

[0002] As domestic construction continues to expand, the number of super-high-rise buildings is increasing. Typically, the core tubes of super-high-rise buildings utilize a building platform process. To facilitate core tube concrete construction, concrete placing booms are used to assist in pouring. Therefore, the placement of concrete placing booms within the building platform affects the concrete construction of the entire core tube area.

[0003] Conventional concrete placing boom deployment method 1 involves using a tower crane to lift the concrete to the construction floor during each concrete pour. Once the concrete pour is complete, the crane is then lowered to the open space for the next pour. Improved concrete placing boom deployment method 2 involves pre-setting holes in the building platform and installing a hydraulic, self-climbing concrete placing boom on the substructure, allowing it to ascend with the structure.

[0004] The traditional approach described above completely separates the concrete placing boom from the building platform. Method 1 significantly increases the workload of tower crane lifting. Furthermore, as the structure's construction height increases, the repeated lifting of the concrete placing boom poses safety risks. The improved method, Method 2, creates reserved openings on each floor. These numerous openings create numerous safety hazards, and the labor costs associated with re-filling these openings also increase.

[0005] To this end, the patent with announcement number CN106049858B discloses a supporting platform for a concrete placing machine of a building construction platform, which is installed on the top between multiple groups of building construction platforms to realize the installation of the concrete placing machine and solve the above problems.

[0006] However, in actual construction, there will be a situation where the building platform positions are not parallel and side by side, but vertical, that is, the building platform on one side of the core tube is along the horizontal direction, and the building platform on the other side is along the vertical direction. Moreover, due to special reasons of the project, the lower return heights of the two sets of frames are different. The top beam of the building platform has two layers, and the height difference causes the top height of the first-layer beam on the top of the building platform on one side to be the same as the second-layer height of the top of the building platform on the other side. If it is arranged on the top of the building platform, it will cause the fabric machine to tilt and construction will be impossible. However, if it is supported on the first-layer beam at the high machine position and the second-layer beam at the low machine position to ensure levelness, the structural strength is weak and there is a safety hazard.
