[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0025] Please refer to FIGS. 1-4. A thin-walled steel arc beam includes: a main board 1, with a side board 2 welded to each side of the main board 1. Two rotating shafts 3 are rotatably arranged between the two side boards 2. A rotating plate 4 is fixedly sleeved outside the rotating shaft 3. A suspension hole 41 is formed in the rotating plate 4. The two rotating plates 4 are symmetric about the center of the main board 1.
[0026] Specifically, in the present utility model, by rotatably arranging the rotating shaft 3 between the two side boards 2 and fixedly sleeving the rotating plate 4 outside the rotating shaft 3, when hoisting the arc beam composed of the main board 1 and the side boards 2, the two rotating plates 4 are directly rotated to the vertical state, and the arc beam is hoisted by passing the hook of the crane through the suspension hole 41, avoiding the process of tying up the arc beam, accelerating the project progress. And after the installation is completed, the two rotating plates 4 can be rotated between the two side boards 2 and welded to act as the reinforcing ribs of the arc beam, enhancing the compressive capacity of the arc beam.
[0027] Furthermore, a plurality of inclined plate reinforcing ribs 5 are welded between the two side boards 2, and all the inclined plate reinforcing ribs 5 are located above the main board 1.
[0028] Specifically, referring to Figure 1 , the two side boards 2 are welded to both sides of the main board 1, and the two ends of the inclined plate reinforcing rib 5 are respectively welded to the inner side walls of the two side boards 2. The plurality of inclined plate reinforcing ribs 5 act as the reinforcing ribs of the arc beam, increasing the compressive capacity of the arc beam.
[0029] Furthermore, a plurality of flat plate reinforcing ribs 6 are welded between the two side boards 2. The flat plate reinforcing ribs 6 are located below the main board 1 and are arranged parallel to the horizontal plane. Six screw holes 61 are formed in the flat plate reinforcing ribs 6.
[0030] Specifically, referring to Figure 2 , by welding a plurality of flat plate reinforcing ribs 6 between the two side boards 2 to enhance the compressive capacity of the arc beam, and the flat plate reinforcing ribs 6 are arranged parallel to the horizontal plane. When installing the arc beam, the screw holes 61 and the temporary support rods can be connected by screws for the support and positioning of the arc beam to prevent the arc beam from shifting.
[0031] Further, two welding plates 21 are welded on the side plate 2, and the distance between the outer side of the welding plate 21 and the center of the rotating shaft 3 is less than the length of the rotating plate 4.
[0032] Specifically, when the upper top surface of the welding plate 21 contacts the side surface of the rotating plate 4, the side surface of the rotating plate 4 is parallel to the horizontal plane, which makes the gap between the upper top surface of the welding plate 21 and the side surface of the rotating plate 4 not too large, facilitating welding the welding plate 21 and the rotating plate 4 together.
[0033] Further, an anti-slip pad 7 is fixedly connected inside the suspension hole 41.
[0034] Specifically, referring to Figure 4 , by setting the anti-slip pad 7, the friction between the anti-slip pad 7 and the crane hook is increased, making it more stable when lifting the arc beam.
[0035] Further, the width of the rotating plate 4 is slightly smaller than the width of the main board 1.
[0036] Specifically, referring to Figure 1 , when the rotating plate 4 rotates into the space between the two side plates 2 and contacts the welding plate 21, the gaps between the rotating plate 4, the welding plate 21, and the rotating shaft 3 are not large, facilitating welding the three together.
[0037] Further, a first plug-in board 42 and a second plug-in board 43 are respectively embedded in the two rotating plates 4, and the first plug-in board 42 and the second plug-in board 43 are plugged and matched with each other.
[0038] Specifically, referring to Figure 3 and Figure 4 , the first plug-in board 42 and the second plug-in board 43 are respectively welded in the grooves opened on their respective rotating plates 4. When the two rotating plates 4 rotate to the vertical direction, the first plug-in board 42 and the second plug-in board 43 are plugged into each other, which makes the angle range within which the two rotating plates 4 can rotate together smaller, avoiding large swings between the two rotating plates 4 and the arc beam body when the crane lifts the arc beam, and reducing potential safety risks.
[0039] In the present utility model, referring to Figures 1 to 4 , first, rotate the two rotating plates 4 to the vertical state so that the first plug-in board 42 and the second plug-in board 43 are plugged into each other. Then, pass the hook of the crane through the suspension holes 41 opened on the two rotating plates 4. After the crane lifts the arc beam to the designated position, use screws to connect the temporary support rod and the screw hole 61. Finally, remove the hook, rotate the rotating plates 4 to between the two side plates 2, weld the rotating plates 4 to the welding plates 21, and also weld the rotating plates 4 and the side plates 2.
[0040] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
