Description
Technical Field
The utility model relates to a steel construction beam column technical field, in particular to be used for steel construction beam column to connect reinforced (rfd) telescopic connecting device.
Background
The assembled steel structure has become a new trend of building development in China in recent years, has the advantages of environmental protection, recycling and the like, can save energy and reduce pollution to the maximum extent, and is a green building which accords with sustainable development.
In the anti-continuous collapse design of the structure, the node is the most important part, after the vertical bearing component is damaged, no matter a 'alternative path method' paying attention to the overall performance or a 'tie strength method' paying attention to local components, the node plays an important role in the anti-continuous collapse of the structure, whether the node is effective and reliable or not is determined, whether a sufficient effective internal force full distribution path exists in the structure or not is determined, and whether the structure can effectively form a 'suspension cable effect' in a large deformation state or not is determined to redistribute the internal force, so that the combined node in the existing building and the newly-built building is necessary to be reinforced to improve the anti-collapse capability of the structure. When a traditional combined node is reinforced, the bearing capacity and rigidity of the node are improved by increasing the section size of a component so as to achieve the purpose of improving the collapse resistance of the node, but the bearing capacity of the node is improved, particularly the rigidity of the node, so that the rigidity of the reinforced node is changed, the performance of the reinforced node is not matched with that of the unreinforced node, and the internal force distribution of the structure under normal use load is influenced. Therefore, a strengthening method which does not affect the rigidity of the node is needed.
Therefore, the anti-collapse structure which is designed and developed with a device for preventing the beam-column connecting point from collapsing due to damage when the beam-column connecting point is greatly deformed so as to improve the integral rigidity of the structure is urgent and particularly significant.
Disclosure of Invention
In order to solve the technical problem, an object of the utility model is to provide a telescopic connecting device for steel construction beam column connects reinforcement has simple structure, convenient and practical, characteristics that the bearing capacity is strong.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a telescopic connecting device for steel structure beam column connects reinforcement, includes the steel frame roof beam 2 that vertical steel frame post 1 and level set up, steel frame post 1 be the right angle setting with steel frame roof beam 2, be located and be connected through sleeve 3 between 2 lower surfaces of steel frame roof beam and the steel frame post 1 and the 2 junction downside of steel frame roof beam, sleeve 3 is fixed through high strength bolt 5 with steel frame roof beam 2 and the 1 junction of steel frame post.
And a stiffening rib 4 is arranged between the steel frame column 1 and the steel frame beam 2.
The sleeve 3 is a hollow steel pipe with the upper caliber smaller than the lower caliber and similar to a fishing rod.
