Problems solved by technology
However, with the increase of service time, welded hollow ball joints will appear weld cracking, sphere corrosion and other phenomena, resulting in the relative wall thickness of the sphere becoming thinner, reducing the bearing capacity of the joint, and severe shear failure will occur
[0003] The existing welding hollow ball joint reinforcement method is mostly realized by welding the outer ribs, but there are many problems in the field welding such as long construction time, unguaranteed weld quality, and difficult welding, which affects the construction quality
At the same time, there are already many welds at the joints, so it is not suitable to weld again

Embodiment 1
[0023] Such as Figure 1~4 As shown, an assembled welded hollow ball joint reinforcement device with adjustable rib position, including upper hoop member 1, lower hoop member 2, outer rib plate assembly, steel gasket 3 and friction type high-strength bolt 4; the upper part The hoop member 1 is fixed on the top of the hollow ball 5, and the lower hoop member 2 is fixed on the bottom of the hollow sphere 5; the upper and lower hoop members are fastened by steel gaskets 3 and friction-type high-strength bolts 4; the outer rib assembly is set on On the outer surface of the hollow sphere 5, the outer rib assembly can be placed on the outer surface of the hollow sphere according to the specific conditions at the nodes, and the number of outer rib assemblies can be set according to the reinforcement requirements. Generally, two sets of outer rib assemblies are arranged at each node. Make sure to arrange them evenly along the spherical surface.
[0024] The upper and lower hoop compo...

The invention discloses an assembly type welding hollow sphere joint reinforcing device with position-adjustable rib plates. The assembly type welding hollow sphere joint reinforcing device with the position-adjustable rib plates comprises an upper hoop component, a lower hoop component, an outer rib plate assembly, a steel gasket and a friction type high-strength bolt, the upper hoop component is fixed to the top of a hollow sphere, the lower hoop component is fixed to the bottom of the hollow sphere, the upper hoop component and the lower hoop component are fastened through the steel gasket and the friction type high-strength bolt, the outer rib plate assembly is arranged on the outer surface of the hollow sphere, the upper hoop component and the lower hoop component are respectively formed by welding an upper plate, a lower plate and a connecting plate, the outer rib plate assembly is formed by welding an outer rib plate and a clamping buckle, and bolt holes are reserved in the corresponding position of the clamping buckle and correspond to notches formed in the upper plates and the lower plates of the hoop components. The reinforcing device is of an assembly type, all components are easy to machine and install, lug plates and the gaskets are universal components, and a large amount of cost can be saved when the reinforcing device is installed; and the reinforcing device is simple in structure, small in installation difficulty, capable of greatly saving construction cost and good in economic benefit.
Description
technical field [0001] The invention relates to an assembled welded hollow ball joint reinforcement device with adjustable rib plate positions, which belongs to the technical field of structural engineering. Background technique [0002] Welded hollow sphere joints are widely used in long-span structures in my country as an economical and applicable joint form. However, with the increase of service time, welding seam cracking and sphere corrosion will occur in welded hollow sphere joints, which will cause the relative wall thickness of the sphere to become thinner, reduce the bearing capacity of the joint, and seriously shear failure will occur. [0003] The existing welded hollow ball joint reinforcement method is mostly realized by welding the outer ribs, but there are many problems in the field welding, such as long construction time, unguaranteed weld quality, and difficult welding, which affects the construction quality. At the same time, there are already many welds a...
