Problems solved by technology
[0004] When the standard C-shaped frame and the load-bearing beam are combined to be used as an external support system, it is necessary to add an upper pull-down support connection node on the two-beam integrated C-shaped frame, but this connection node is only suitable for tower cranes below 2000t m For super-large boom tower cranes, when the two beams are combined into one, the force transmission and calculation of the connection nodes of the upper and lower braces are complicated, the calculation is complicated, the force transmission path is difficult to deduce, and the welding deformation during tailor welding is difficult to control and difficult to guarantee. welding quality

The invention provides an upper pulling and lower supporting rod piece supporting beam device for installation of a large movable arm tower crane C-shaped frame. A horizontal supporting beam is used for supporting the C-shaped frame with two beams combined into one. An oblique pulling rod embedded part and an oblique supporting rod embedded part are arranged in the vertical direction and are embedded in a first building structure and a second building structure correspondingly. The oblique pulling rod embedded part is located above the oblique supporting rod embedded part. The two ends of a vertical oblique pulling rod are connected with the oblique pulling rod embedded part and the horizontal supporting beam correspondingly and are used for pulling the horizontal supporting beam. The two ends of a vertical oblique supporting rod are connected with the oblique supporting rod embedded part and the horizontal supporting beam and are used for supporting the horizontal supporting beam. A splayed shape rotating clockwise by 90 degrees is formed by the vertical oblique pulling rod and the vertical oblique supporting rod, and the vertical oblique pulling rod is located above the vertical oblique supporting rod. According to the upper pulling and lower supporting rod piece supporting beam device for installation of the large movable arm tower crane C-shaped frame, definite force transmission can be ensured, welding deformation is reduced, the welding quality is ensured, design is ingenious, the structure is simple, the cost is low, and the device is suitable for large-scale application and popularization.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to the technical field of installing a C-shaped frame of a large-scale movable arm tower crane, and specifically refers to a device for installing a C-shaped frame of a large-scale movable arm tower crane with an upper pull-down support member and a joist. Background technique [0002] At present, the support system used by super-large external boom tower cranes is a combination of a standard C-shaped frame and an independently designed support system, which is heavy and complicated to connect. [0003] After the integration and optimization of the standard C-shaped frame and the load-bearing beam, the standard C-shaped frame and the load-bearing beam are combined into one, which reduces the weight of the load-bearing beam of the independently designed support system, reduces the construction cost, and reduces the unloaded weight and transmission to The weight of the a...
