Supporting structure capable of adjusting displacement of net rack joint and construction method thereof

Abstract

The invention discloses a supporting structure capable of adjusting displacement of a net rack joint and a construction method. The supporting structure comprises a supporting plate supported at the bottom of the net rack joint, an upper bearing plate arranged at the bottom of the supporting plate, a lower bearing plate connected by a loading bolt and positioned below the upper bearing plate, anda groove-shaped steel beam installed on a scaffold cross rod, wherein the lower bearing plate is fixed on the groove-shaped steel beam, an adjusting nut for adjusting the displacement of the upper bearing plate is arranged on the loading bolt, the top of the supporting plate is provided with a radian matched with the net rack joint, the upper bearing plate and the lower bearing plate are formed bysplicing two steel plates with semi-circular arc notches, and the semi-circular arc notches are oppositely arranged to form a through hole in which an original steel pipe penetrates. The displacementof the net rack joint is adjusted by adjusting the adjusting nut on the loading bolt, a damaged or unstably rod is completely unloaded, and therefore the rod is reinforced or replaced. The structureis simple and flexible, can be used for reinforcing any joint, is convenient to construct, can completely maintain the shape of the original structure, and basically does not change the original forcetransmission path.

Description

technical field [0001] The invention belongs to the technical field of steel structure reinforcement, and in particular relates to a support structure and a construction method capable of adjusting the displacement of network frame nodes. Background technique [0002] The grid structure refers to the space grid structure formed by connecting multiple rods through nodes. Most of the grid structure is made of steel pipes and spherical nodes. It has simple structure, convenient connection, and simple force transmission. It can be applied to large-span space structures and saves steel materials. Therefore, grid structures have been widely used in recent years. However, in the process of application, the strength, stiffness, and stability of steel structures have become increasingly prominent. Since grid structures are used in long-span high-altitude buildings, once the structure is partially damaged or unstable, it is very difficult to repair or replace components. At present, ...

Problems solved by technology

However, in the process of application, the strength, stiffness, and stability of steel structures have become increasingly prominent. Since grid structures are used in long-span high-altitude buildings, once the structure is partially damaged or unstable, it is very difficult to repair or replace components. At present, there is no simple and effective support structure for grid node reinforcement, and there is no relatively uniform construction method for reinforcement or replacement of grid members. It is difficult to maintain the original shape and shape during the reinforcement or replacement of grid nodes. The original force transmission path
