[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are all in very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. For the convenience of description, the "upper" and "lower" described below are consistent with the upper and lower directions of the drawings, but this cannot be a limitation of the technical solution of the present invention.
[0017] This embodiment takes the construction of a large steel structure industrial plant as an example. There is a steel structure corridor with a span of 14.9m between the second to sixth floors of Buildings 6-4 and 6-5 of this project. Figure 1As shown, the steel structure corridor includes a horizontal steel beam 4, a support 3 and a steel structure corbel 2. A pair of steel structure corbels 2 are symmetrically arranged and respectively connected to the buildings on both sides. The horizontal steel beam 4 is erected on the top of a pair of steel structure corbels 2. Both ends of the horizontal steel beam 4 are respectively connected to the steel structure corbels 2 through the supports 3 at the bottom thereof. The steel structure corridor has a large span and a high erection height, and is greatly affected by wind loads. Moreover, in the later use of the steel structure industrial plant, the steel structure corridor needs to carry the entry and installation of large equipment. The steel structure corridor usually uses steel structure corbels 2 as vertical supports. The corbel position is the force concentration point of the entire steel structure corridor, carrying the entire corridor structure and its upper load. The corbel node is subjected to large force and the force form is complex, and it is impossible to reserve sufficient safety space for the later use of the high-altitude large-span steel structure corridor. Therefore, the corbel node is one of the key points and difficulties in the construction of the high-altitude large-span steel structure corridor. Based on the accurate analysis and research on the problems of the corbel nodes of high-altitude large-span steel structure corridors, the inventor proposed the following solution: adding a node reinforcement structure at the bottom of the original steel structure corbel 2, and using the node reinforcement structure to provide additional support and improve the force distribution, that is, by increasing the support points, the overall stability of the steel structure corridor is effectively enhanced, and at the same time the load is dispersed to reduce the load borne by the original steel structure corbel 2, thereby improving the structural safety of the high-altitude large-span steel structure corridor.
[0018] Combine the following Figures 1 to 3 The node reinforcement structure of the steel structure corridor corbel of the utility model is described, the node reinforcement structure is connected to the bottom of the original steel structure corbel 2, and one side of the node reinforcement structure is connected to the frame column 1. The node reinforcement structure includes a transverse stiffening rib 51, a longitudinal stiffening rib, a side plate 54 and a bottom plate 55. A transverse stiffening rib 51 is vertically arranged along the axis direction of the original steel structure corbel 2, at least two pairs of longitudinal stiffening ribs are symmetrically and spaced along the transverse stiffening rib 51, and each longitudinal stiffening rib is vertically connected to the transverse stiffening rib 51, the side plate 54 is vertically arranged on the side away from the frame column 1 and vertically connected to the side of the transverse stiffening rib 51, and the bottom plate 55 is horizontally arranged at the bottom of the transverse stiffening rib 51 and is respectively connected to the frame column 1, the transverse stiffening rib 51 and a pair of longitudinal stiffening ribs.
[0019] The node reinforcement structure of the steel structure corridor corbel of the utility model comprises a transverse stiffening rib 51 vertically arranged along the axis direction of the original steel structure corbel 2, at least two pairs of longitudinal stiffening ribs symmetrically and spaced apart along the transverse stiffening rib 51, a side plate 54 vertically arranged at a side away from the frame column 1 and vertically connected to the side of the transverse stiffening rib 51, and a bottom plate 55 horizontally arranged at the bottom of the transverse stiffening rib 51 and respectively connected to the frame column 1, the transverse stiffening rib 51 and the longitudinal stiffening rib; in view of the load and structural characteristics of the original steel structure corridor, a node reinforcement structure is added at the bottom of the original steel structure corbel 2, and each component of the node reinforcement structure is vertically or symmetrically arranged along the axis direction of the original steel corbel, that is, the overall size of the node reinforcement structure is basically the same as that of the original steel corbel, and the axes of the two are consistent, the node reinforcement structure can be accurately positioned and effectively combined with the original steel corbel and the frame column 1 as a whole, thereby ensuring the effective transmission of the force of the original corbel support structure, strengthening and reinforcing the corbel node and reasonably sharing the load. , so that the corbel node can withstand the complex loads in the high-altitude working environment, and enhance the stability and structural safety of the steel structure corridor node; compared with the original corbel support structure, the node reinforcement structure can provide additional support, improve the force distribution of the node, reduce the risk of structural failure or damage, and ensure the stability and safety of the steel structure corridor during use; the setting of the node reinforcement structure can also improve the load distribution of the node, so that the corbel node can bear the pressure more evenly, which helps to reduce the burden of the original corbel support structure, improve the overall bearing capacity of the structure, reduce the fatigue and loss of the structure, and extend the service life of the structure; therefore, the node reinforcement structure of the steel structure corridor corbel of the utility model can improve the overall performance of the steel structure corridor, and provide a solid guarantee for the safe construction and long-term operation of the high-altitude corridor project.

[0022] In this embodiment, the thickness of the transverse stiffening ribs 51, the longitudinal stiffening ribs, the side plates 54 and the bottom plate 55 is at least 20 mm to ensure the overall structural strength of the node reinforcement structure.
[0023] The connection nodes of the transverse stiffening ribs 51 and the longitudinal stiffening ribs in the node reinforcement structure, as well as the connection nodes between the transverse stiffening ribs 51 and the original steel corbels and frame columns 1, are all welded by double-sided welding, such as double-sided manual arc welding or automatic gas shielded welding. Before double-sided welding, it is necessary to ensure that the surface of the welded component is thoroughly cleaned and free of grease, dirt or oxides; adjust the current and voltage of the welding machine to ensure uniform and stable welding. Operation steps: First, weld on the first side of the component connection node, and then weld the second side symmetrically, ensuring that the welding quality of the first side is cleaned and checked before welding; after welding, perform quality inspection of the weld, including visual inspection and possible non-destructive testing; finally, record and report the quality control and quality inspection results of the double-sided welding operation to ensure the double-sided welding quality and structural stability of the node.
