Description

Technical Field

[0001] This utility model relates to the field of arch rib segment flipping technology, and in particular to an arch rib segment flipping device. Background Technology

[0002] In the construction of modern steel arch bridges, a common strategy is to break down the arch bridge structure into several arch rib segments to facilitate efficient prefabrication in specialized steel structure processing plants. Common steel arch bridge forms include steel truss arches, steel box-truss composite arches, steel box arches, and irregularly shaped steel arches. Although these arch rib segments are relatively optimized in size and easy to manufacture, the size and weight of each segment are still significant during on-site assembly. These segments can be tens of meters long and high, and weigh around 150 tons. Therefore, during assembly, the arch ribs are laid flat. After assembly, when the arch ribs need to be installed, the segments are flipped upright and transported to the arch bridge for installation. However, if the arch rib segment itself is used as the flipping axis during the verticalization process, the work is very difficult and can damage the local structure of the arch rib segment, thus affecting the structural safety of the entire bridge. Therefore, there is an urgent need to develop a device that helps the arch rib segments to flip over, ensuring the structural integrity of the arch rib segments during the flipping process, so as to guarantee the quality and safety of the project.

[0025] Example. An arch rib segment flipping device, structural reference. Figure 1 The device includes a base 1, a side plate 2 on one side of the top surface of the base 1, and a card seat 3 at the center of the top surface of the base 1. The bottom of the side of the base 1 with the side plate 2 is arc-shaped. The arc-shaped curve of the base 1 includes a quadratic parabola, a spiral, and a logarithmic curve. By setting the base 1 in an arc shape, it is easy to flip over. At the same time, the use of quadratic parabolic, spiral, and logarithmic curves ensures a smooth flipping process.

[0026] The base 1 includes several parallel longitudinal plates 4, which are connected by several transverse plates 5.

[0027] The arc-shaped portion of the base 1 is provided with a transverse stiffening structure 6; by providing a transverse stiffening structure 6 in the arc-shaped portion, the structural rigidity of the base 1 is ensured, and the base is prevented from being damaged during the flipping process.

[0028] The dimensions of the card holder 3 are matched to the width of the arch rib segment; the card holder 3 includes several parallel baffles, the baffles are arranged in right-angled trapezoids, the longer base of the right-angled trapezoids contacts the arch rib segment 7, and the baffles are laterally connected by steel plates.

[0029] The transverse stiffening structure 6 includes H-beams, angle steel, and steel pipes;

[0030] The base 1, side plate 2 and card slot 3 are made of Q235 steel or Q345 steel;

[0031] This utility model has been put into use in engineering. It is made of Q235 steel and consists of a base 1 composed of four longitudinal plates 4, three transverse plates 5, and side plates 2. The transverse stiffening structure 6 of the arc-shaped part of the base 1 is made of H-beams. When in use... Figure 3 and 4 As shown, the side plate 2 of this device is flipped to contact the ground, and the arch rib segment 7 is assembled on the side plate 2. Depending on its size, no less than two of this device are arranged at the bottom of the arch rib segment 7. After the arch rib segment 7 is assembled, the mounting bracket 3 is welded on the top surface of the base 1 to ensure that the mounting bracket 3 is in close contact with the arch rib segment 7. When it is necessary to flip the arch rib segment 7, the end of the arch rib segment 7 away from this device is lifted by lifting equipment such as a gantry crane, so that the arch rib segment 7 is gradually flipped vertically along the arc-shaped part of the base 1 with this device as the axis.
