Description
Technical Field
The utility model belongs to the architectural equipment field, in particular to a sleeve pipe device for bending and shearing steel component reinforcement.
Background
The steel structure and the mixed structure are very suitable for building space structures, super high-rise buildings, industrial plants and other building structures due to the advantages of the characteristics of the steel structure and the mixed structure. As related industries of steel structures and hybrid structures are rapidly developed, their share in the construction market is rapidly increased. At present, steel structures and hybrid structures are widely present in existing industrial and civil buildings.
In the whole service life of the existing steel member, on one hand, in the use process, the change of the use function can cause the increase of the bearing load of the structure; on the other hand, the structure not only bears the action of constant load such as self weight for a long time, but also can bear various adverse effects caused by environmental erosion, explosion, impact and vibration load, earthquake action, wind load and the like, and the results of resistance attenuation of structural members, material aging and the like are caused.
The steel member is often long and thin, and the instability and the damage of the steel member under the action of bending shear are the largest failure modes. Because the instability damage of the steel member has the characteristic of brittle damage, the main steel member is subjected to pressure instability, the integral structure can be subjected to local instability and integral instability, the structure is subjected to brittle and continuous collapse damage, and finally the integral structure loses the capability of resisting external loads. Therefore, the existing press-bending steel members in which these problems occur need to be reinforced as necessary to increase the safety of the structure.
The construction method for reinforcing the stability of the bending shear steel member mainly comprises load reinforcing, unloading reinforcing and replacing member reinforcing. Unloading reinforcement is not only uneconomical but also affects normal use, and replacing reinforcement of steel members often requires modification of the structural configuration and causes redistribution of internal forces, which poses a great safety risk. Reinforcement modification often requires that the impact on the service function be minimized, and therefore reinforcement under load becomes an important requirement in reinforcing steel members. Welding or bolting reinforcement under load is dangerous. When the welding technology is used for reinforcing the structure, the microstructure and the mechanical property of the welding part are changed when the welding part is subjected to high temperature, and irreversible additional deformation and additional stress of the structure are easily caused. When the bolt is adopted for connection, the cross section of the base material is weakened, and a new stress concentration area is generated near the opening, so that the adverse effect on the reinforcing effect is generated. The problems that stability reinforcement is carried out under the load condition of the bending and shearing steel rod piece and welding operation on a construction site is reduced as much as possible are urgently solved.
