Description

Technical Field

[0001] The utility model relates to the technical field of combined steel beams, in particular to a combined steel beam with reinforced nodes. Background Art

[0002] A composite steel beam is a new type of structure formed by combining a steel beam and a concrete flange through connectors. This structure uses shear connectors between the steel beam and the concrete flange to resist uplift and relative slippage at the interface between the two, allowing them to work together as a whole. When the steel beam and concrete bridge deck are connected by connectors, they cannot freely slip relative to each other and share the longitudinal bending moment of the bridge. This is called a composite steel beam. Compared with traditional single-material structures, composite steel beams have significant advantages in load-bearing capacity, seismic performance, and construction efficiency. To improve the overall stability of the building, a composite steel beam is needed, but existing composite steel beams still have the following shortcomings:

[0003] When existing composite steel beams are used, since most composite steel beams are assembled and installed using only a single structure, the node stability of the composite steel beams is poor during use, which affects the overall firmness of the composite steel beams and causes the practicality of the composite steel beams to decrease and the efficiency of use to decrease.

[0004] Therefore, in view of this, the existing structure and its deficiencies were studied and improved, and a composite steel beam with node reinforcement was proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a combined steel beam with reinforced nodes to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a node-reinforced composite steel beam, comprising a steel beam body, a reinforcement block and a reinforcement support frame, a flange plate body is arranged above the steel beam body, and limit blocks are added on both sides of the upper end of the steel beam body, and limit grooves are provided on both sides of the lower end of the flange plate body, reinforcement blocks are distributed on both sides of the lower end of the steel beam body, and a threaded mounting groove is provided inside the reinforcement block, and a first mounting bolt is connected inside the threaded mounting groove, reinforcement support frames are added on both sides of the outside of the steel beam body, and a second mounting bolt is connected inside the reinforcement support frame.

[0007] Furthermore, the outer side of the steel beam body and the outer side of the flange plate body are horizontally distributed, and the outer side of the steel beam body and the outer side of the flange plate body are tightly fitted.

[0008] Furthermore, the outer dimensions of the limiting block are adapted to the inner dimensions of the limiting groove, and the limiting block is embedded in the flange plate body through the limiting groove.

[0009] Furthermore, there are two limit blocks, and the two limit blocks are symmetrically arranged on both sides of the upper end of the steel beam body.

[0010] Furthermore, the reinforcement block is in an "L" shape, and the inner side of the reinforcement block is tightly fitted with the outer side of the steel beam body.

[0011] Furthermore, the outer side of the reinforcement block is horizontally distributed with the outer side of the flange plate body, and the reinforcement block is fixedly connected to the flange plate body by a first mounting bolt.

[0012] Furthermore, the inner dimension of the threaded mounting groove is adapted to the outer dimension of the first mounting bolt, and the first mounting bolt is rotatably connected to the reinforcement block through the threaded mounting groove.

[0013] Furthermore, the number of the reinforcement support frames is set to six, and three of the reinforcement support frames form a group, and each group of the reinforcement support frames is symmetrically arranged on both sides of the outside of the steel beam body.

[0014] The utility model provides a combined steel beam with reinforced nodes, which has the following beneficial effects:

[0015] 1. The utility model provides a limit block, so that when the node reinforced composite steel beam is used, the limit block can be fixedly installed on both sides of the upper end of the steel beam body by tightening bolts. At the same time, the external size of the limit block matches the internal size of the limit groove opened on both sides of the lower end of the flange plate body, so that the flange plate body can be quickly limited to the upper end of the steel beam body by the limit block and the limit groove, thereby avoiding position deviation when the steel beam body and the flange plate body are connected, and improving the convenience of the subsequent installation process of the composite steel beam.

[0016] 2. The utility model provides a reinforcement block, so that when the combined steel beam reinforced at the node is used, the reinforcement block can be docked at the connection between the steel beam body and the flange plate body, and the reinforcement block can be fixedly installed under the steel beam body and the flange plate body through the threaded installation groove and the first installation bolt. After the installation is completed, the inner side of the reinforcement block fits tightly with the outer side of the steel beam body, the reinforcement support frame is installed at the connection between the reinforcement block and the steel beam body, and the second installation bolt is used to further improve the installation stability, so that the steel beam body and the flange plate body are stably installed, thereby improving the firmness and stability of the combined steel beam during use.
