As shown in fig. 1-3, the i-shaped crane beam according to the present utility model mainly comprises an upper flange 1, a lower flange 4 and a web plate 3, wherein the upper flange 1 and the lower flange 4 are parallel to each other, the web plate 3 is vertically and fixedly connected between the upper flange 1 and the lower flange 4, and the upper flange 1, the lower flange 4 and the web plate 3 together form an i-shaped crane beam structure.
In order to improve the structural stability of the I-shaped crane beam, stiffening ribs 2 are generally fixed on two lateral sides of the web plate 3, and the stiffening ribs are perpendicular to the upper flange 1, the lower flange 4 and the web plate 3.
As described above, in order to reinforce the crane beam on site in a state of no production stop, the I-shaped crane beam reinforcing structure provided by the utility model is characterized in that a reinforcing steel plate is additionally arranged on the basis of the original I-shaped crane beam. Specifically, as shown in fig. 1-3, the reinforcing steel plate 5 is fixed on the outer sides of the two stiffening ribs 2, and the length of the reinforcing steel plate 5 is equal to that of the web 3, two ends of the reinforcing steel plate 5 are fixedly connected with the upper flange 1 and the lower flange 4 respectively, and the inner side edge of the reinforcing steel plate 5 is fixedly connected with the stiffening ribs 2.
The reinforcing steel plate can be parallel to the web plate, and the reinforcing steel plate, the upper flange/lower flange and the stiffening rib are perpendicular to each other, so that the conventional I-shaped crane beam and the reinforcing steel plate form a III-shaped section, and the purpose of reinforcing the original I-shaped crane beam under the conditions of no replacement and no disassembly is achieved.
Compared with the traditional reinforcement technology, the utility model has the advantages that normal production is not affected, the construction is convenient, the structure is safe and reliable, the construction period is obviously shortened, the engineering cost is reduced, the reinforcement plate is fixed with the upper flange and the lower flange at the same time, the integral reinforcement of the original I-shaped crane beam can be effectively realized, the bearing capacity of the reinforced I-shaped crane beam structure is stronger, and the reinforcement effect is better.
In one embodiment of the present utility model, the fixing manner between the structural members is welding. Specifically, the upper flange 1, the lower flange 4, the web plate 3 and the stiffening rib 2 are all steel plates, two ends of the web plate 3 are welded and fixed with the upper flange 1 and the lower flange 4 respectively, and the inner side edge of the stiffening rib 2 is welded and fixed on the side wall of the web plate. Two ends of a fixed steel plate 5 (parallel to the web 3) are respectively welded and fixed with the upper flange 1 and the lower flange 4; the inner side wall of the fixed steel plate 5 is welded and fixed with the outer side edge of the stiffening rib 2.

The equal strength design of the weld joint mainly means that the mechanical properties (particularly tensile strength) of the welded joint are equivalent to those of the base material, and in most cases, the tensile strength of the joint is required to be not lower than that of the base material, but not the full-thickness penetration of the welded steel plate. Butt welds require penetration mainly because they are mostly load-bearing welds, which are required to avoid high stress concentrations and initiate weld cracks during use.
Therefore, equal-strength welding is adopted between the fixed steel plate and the upper flange 1, the lower flange 4 and the stiffening rib 2, so that the welding quality can be effectively improved, and the reinforcement performance of the I-shaped crane beam is ensured.

The reinforced steel plate can be manufactured in a steel structure processing factory according to the design requirement before being installed, and the factory manufacturing is easy to ensure the processing precision and has high speed.
According to the technical scheme, the I-shaped crane beam reinforcing structure provided by the utility model can integrally improve the bearing performance of the I-shaped crane beam through the respective welding and fixing of the reinforcing steel plate, the upper flange, the lower flange and the stiffening rib; and the reinforcement purpose can be realized under the conditions of no replacement and no disassembly. Compared with the prior art, the method has the advantages of no influence on production, convenient construction, safe and reliable structure, obviously shortened construction period, reduced construction cost and obvious economic and social benefits for construction parties.
