Description

Adjustable wedge-shaped supporting equipment for casting fish web girder Technical Field The invention belongs to the technical field of fish belly sill supporting equipment, and particularly relates to adjustable wedge-shaped supporting equipment for casting a fish belly sill. Background The fish belly beam is a variable cross-section beam, and is characterized in that the cross-section size is gradually increased from two ends to the middle of the beam, and the whole contour is similar to a fish belly. The exquisite design ensures that the fish belly sill can distribute stress more efficiently when bearing load, and the bearing capacity and stability of the structure are obviously improved. Under the action of uniformly distributed loads, the bending moment diagram of the beam presents a parabolic shape, wherein the mid-span bending moment reaches the maximum value, the bending moment at the two ends is relatively smaller, the variable cross-section design of the fish-bellied beam skillfully enables the cross-section resisting moment (namely bending-resistant cross-section coefficient) of the beam to be matched with the bending moment diagram, the mid-span cross-section resisting moment is larger, the two ends are smaller, further, the uniform distribution of stress is realized, and the waste of materials is effectively avoided. Meanwhile, as the fish belly sill has larger cross-sectional dimension at the midspan position, the rigidity is relatively high, deformation can be better resisted when the fish belly sill bears load, and the stability of the structure is ensured; along with the vigorous development of modern bridge construction, the application of the fish belly beam is more and more extensive, and the support requirement is more and more frequent, so that the support equipment has more auxiliary functions to adapt to the support requirement under various complex scenes for guaranteeing the reliability of the fish belly beam support and the convenience of installation. However, the existing support wedge-shaped support device for casting the fish web girder still has the following disadvantages in the use process: 1. Most of the existing fish belly beam supporting equipment is of fixed size and shape, can be assembled in advance and directly transported to a construction site for use during installation, and can also be built in a construction area, but when the fish belly beam is applied to bridge building sites with different spans, the fish belly beam supporting equipment with different supporting lengths is required to be used for overlapping building, and the common fish belly beam supporting equipment does not have an adjusting function, so that a single construction site can only carry out targeted fish belly beam design, the application range of the fish belly beam supporting equipment is limited, and meanwhile, the bridge building cost is increased; 2. The current fish web beam supporting equipment is in the use, especially is when adjusting installation fish web beam to adjustable fish web beam supporting equipment, and the regional gold is happy souvenir angle adjustment that needs is built to fish web beam upper end, and then changes to build the support length, and this in-process, ordinary fish web beam supporting equipment lacks the protection insurance function. In the adjusting process, the condition of overregulation is likely to occur, and the angle of the built structure is excessively rotated to cause toppling, so that the supporting equipment is large in weight and volume, and once toppling, the equipment collapses and is difficult to recover, thereby not only reducing the use safety of the equipment, but also seriously affecting the protective performance of the equipment. Therefore, it is necessary to invent an adjustable wedge support device for casting a fish belly beam to solve the above problems. Disclosure of Invention The invention provides adjustable wedge-shaped supporting equipment for casting a fish belly sill, aiming at the problems and solving the problems in the background technology. In order to achieve the aim, the invention provides the technical scheme that the adjustable wedge-shaped supporting device for casting the fish belly beam comprises two mounting frames, wherein an adjustable fish belly beam supporting mechanism is arranged between the two mounting frames, and safety components are arranged on the side surfaces of the two mounting frames; The adjustable fish belly beam supporting mechanism comprises an adjusting base which is rotatably arranged at one side of the top of two mounting frames, one side of the top of each adjusting base is provided with a mounting roller, the outer walls of the two mounting rollers are rotatably connected with arc-shaped supporting frames, the two ends of the top of each mounting frame are provided with limiting sliding grooves, the inner walls of the four limiting sliding grooves are slidably connected with adjustin
