[0027] Please refer to Figure 1 The present embodiment provides a large-tonnage static load cantilever beam device, which comprises flanges 1, webs 2, reinforcing webs 3 and reinforcing ribs 4.
[0028] The flanges 1 are arranged in parallel from top to bottom, the number of the webs 2 is two, the two webs 2 are arranged vertically between the upper and lower flanges 1, the reinforcing ribs 4 are arranged on the outer sides of the webs 2, and the reinforcing ribs 4 are arranged in intervals, the reinforcing webs 3 are arranged on the reinforcing ribs 4 located at the middle positions of the webs 2, the reinforcing webs 3 located on both sides are parallel, and the reinforcing webs 3 are fixedly connected with the upper and lower flanges 1.
[0029] Specifically, in the present embodiment, the cantilever beam structure composed of flanges 1, webs 2, reinforcing ribs 4, reinforcing webs 3 and reinforcing flanges 5 is designed and constructed according to the characteristics of large-tonnage static load. The present application is based on the upper and lower flanges 1 and the webs 2 located between the upper and lower flanges 1, and reinforcing ribs 4 are additionally arranged at the key stress areas of the cantilever beam, especially at the connection between the webs 2 and the flanges 1. The arrangement of these reinforcing ribs 4 can effectively disperse the load, enhance the local bending stiffness of the cantilever beam, and prevent local buckling or deformation. At the same time, reinforcing webs 3 are additionally arranged at the parts with large stress, which can effectively improve the carrying capacity of the parts and prevent local instability of the wall surface caused by excessive stress.
[0030] The large-tonnage static load cantilever beam device described in the embodiment is composed of flanges 1, webs 2, reinforcing ribs 4, reinforcing webs 3 and reinforcing flanges 5, which significantly improves the stability, load capacity and safety of the cantilever beam device in the large-tonnage static load experiment, effectively solves the problems of insufficient stability and insufficient supporting force of the cantilever beam under large-tonnage static load, and has the advantages of simple structure, convenient processing, simple welding, good welding quality and good combination form while meeting the stress condition.
[0031] In some embodiments, the two webs 2 are arranged in parallel and are enclosed with the upper and lower flanges 1 to form a through gap.
[0032] The reinforcing ribs 4 arranged outside the two webs 2 are correspondingly arranged, and the two ends of the reinforcing ribs 4 are fixedly connected with the upper and lower flanges 1, respectively.
[0033] The length of the web 2 corresponds to the length of the flange 1, the size of the web 2 is 10*1.2m, the thickness of the web 2 is 15.7mm, the size of the flange 1 and the reinforcing flange 5 is the same, both are 10*0.5m, and the thickness of the flange 1 and the reinforcing flange 5 is 20mm.
[0034] Specifically, in the embodiment, the local position is enhanced according to the stress condition in the static load loading process. Further, by reasonably arranging the reinforcing ribs 4 (rib bars) and the position, the bending stiffness of the cantilever beam is enhanced, which can help the cantilever beam to maintain its stability better during the working process and prevent tilting or swinging due to excessive load.
[0035] The distance interval between each reinforcing rib 4 is 1m. Due to the existence of the reinforcing ribs 4, the cantilever beam is divided into multiple stress segments, and the stress condition of each segment is relatively independent, which can effectively reduce the risk of the overall structure and ensure that each segment can independently bear the load.
[0036] In addition, the two webs 2 are arranged in parallel, and the interval distance between the two webs 2 is 234.3mm. The purpose of the two webs 2 arranged at intervals in the scheme is to effectively reduce the overall weight of the device without affecting the overall stress and load capacity of the device, and to reasonably meet the requirements of large-tonnage static load experiment.
[0037] In some embodiments, a placement space is formed between the outer edge of the reinforcing rib 4 and the edge of the flange 1, the reinforcing web 3 is arranged in the placement space, and the outer wall surface of the reinforcing web 3 and the side wall surface of the flange 1 are in the same horizontal plane.
[0038] The upper and lower ends of the reinforcing web 3 are fixedly connected with the two flanges 1, respectively.
[0039] Specifically, in the embodiment, the load-carrying capacity of the part of the area is further improved by setting the reinforcing web 3 outside the reinforcing rib 4, the length of the reinforcing web 3 is 4 m, and the load-carrying capacity of the cantilever beam device is enhanced by the structural design of the reinforcing web 3, the flange 1 and the reinforcing rib 4, so that the cantilever beam device can bear large-tonnage static load without yielding, damage or deformation. The design effectively improves the load distribution capacity of the cantilever beam and ensures uniform distribution of the load in the cantilever beam structure, thereby avoiding potential dangers caused by concentrated stress.
[0040] Meanwhile, the overall appearance of the structure is beautiful, the surface is flat, the structure is simple and stable.
[0041] In some embodiments, the outer side of each of the two flanges 1 is provided with a reinforcing flange 5, and the size of the reinforcing flange 5 is equal to that of the flange 1.
[0042] Specifically, in the embodiment, the thickness of the flange 1 is increased by setting the reinforcing flange 5 outside the flange 1, and the flange 1 is provided with a reinforcing structure as a whole. When the cantilever beam bears large-tonnage static load, it can better resist bending deformation and reduce local stress concentration, effectively increasing the bending stiffness of the cantilever beam device. Meanwhile, the load can be more evenly distributed on the flange 1, avoiding deformation or damage of the flange 1 caused by excessive local stress, which helps to improve the overall load-carrying capacity of the cantilever beam.
[0043] In some embodiments, the flange 1, the web 2, the reinforcing web 3, the reinforcing rib 4 and the reinforcing flange 5 are all made of flat Q345 type steel, and the overall cantilever beam size is 10 * 1.2 * 0.5 m.
[0044] Among them, the flange 1, the web 2, the reinforcing web 3 and the reinforcing rib 4 are fixed by welding, and the flange 1 and the reinforcing flange 5 are fixed by welding.
[0045] Specifically, in the embodiment, the quality of welding directly affects the stability and load-carrying capacity of the whole structure. The cantilever beam device is made of steel plate and welded, especially at the connecting parts of the flange 1, the web 2 and the reinforcing rib 4. The cantilever beam device with good welding can bear larger load and has better overall stability and safety.
