Problems solved by technology
Since the node is the connecting part of the beam-column and the bar, and the column is often connected with multiple beams at the node, it is very difficult to strengthen and repair the node area. At present, there is no mature reinforcement method and technology. important problem
At present, external carbon fiber cloth, external steel plate and external carbon fiber plate reinforcement technologies have been carried out at home and abroad to strengthen the nodes, but in general, the reinforcement effect is not ideal, and the construction is very troublesome, and has not been maturely applied, especially For the steel structure nodes of prefabricated buildings, there is no good reinforcement method at present

Embodiment 1
[0046] See figure 1 , A steel structural node reinforcement method for assembling construction, including the following steps:
[0047] S1, according to the architectural design drawings and assess the force at the steel structure beam node, determine the reinforcement grade, and began to prepare related reinforcement materials;
[0048] S2, a plurality of outer packages of corresponding sizes are prefabricated, and the welding of the associated components is performed, while the suitable pores are reserved at the steel structure beam node;
[0049] S3, pre-mounted the outer package in different directions at the steel structural beam node, and tighten the high strength bolt 5 for anchoring, and then fill the upper 2-5 mm thick structuring between the node and the outer package reinforcement;
[0050] S4, embed the magnetic strip 6 at the edge of the outer package reinforcing member, and the latex cement is used;
[0051] S5, the number of outsourced reinforcements around the pack...

The invention discloses a steel structure node reinforcement method for an assembled building, which belongs to the field of construction engineering, and can support and protect the beam-column nodes of the steel structure by means of outsourcing reinforcement, and utilize the structural characteristics to convert the received external force The way of feedback, in turn, acts on the reinforcement to improve the overall stability of the reinforcement. Among them, the innovative introduction of multi-effect force balls promotes the stability of the structure of the reinforcement on the one hand, and at the same time facilitates the dispersion of external forces and the simultaneous connection of multiple The reinforcement becomes a whole. On the other hand, by using its own characteristics, it adopts the method of first absorbing energy and then decomposing the external force, effectively dissolving the external force transmitted by the reinforcement, and promoting the transformation and feedback of the external force, which not only meets the high strength and high stability required by node reinforcement , At the same time, it has excellent shock absorption and buffering effect, and it can effectively reinforce the joints of steel structure beams and columns with both rigidity and flexibility, which can significantly improve the joint strength of prefabricated buildings, thereby improving building safety and prolonging service life.
Description
Technical field [0001] The present invention relates to the field of construction engineering, and more particularly to steel structural nodes reinforcing steel structural nodes in assembled buildings. Background technique [0002] Assembly buildings refer to the transfer of large number of live operations in traditional construction methods to the factory, producing construction components and accessories in factory (such as floor board, wall panel, stairs, balcony, etc.), transportation to the construction site, pass through Reliable connection is installed on site. [0003] The assembled building mainly includes prefabricated assembled concrete structures, steel structures, modern wood structural buildings, because of the use of standardized design, factory production, assembly construction, information management, intelligent application, is a representative of modern industrial production. [0004] The node is the part of the building structure beam column. It is the key hub...
