Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a steel beam joint structure for a concrete shear wall. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads (gravity) caused by wind or earthquakes. They prevent structural shear failure and are generally made of reinforced concrete.

[0003] Currently, steel-concrete composite shear walls are the most common type of prefabricated green building. The connection between the steel-concrete composite shear wall and the steel beams involves welding reinforcing plates to the outer wall of the steel tube bundle. This connection method is structurally safe and reliable. However, to improve the stability of the connection between the steel beams and the steel-concrete composite shear wall, multiple reinforcing plates are required for each connection node, resulting in a large quantity of reinforcing plates and high costs.

[0004] For example, Chinese patent CN215367854U discloses a connection node between a steel beam and a steel-concrete composite shear wall, relating to the field of building technology. The connection node includes a steel pipe bundle, a reinforcing plate, and a steel beam. The reinforcing plate is disposed on the steel pipe bundle; the reinforcing plate has multiple connecting rods, one end of which is inserted into the steel pipe bundle; one end of the steel beam is connected to the reinforcing plate. Using this invention reduces the number of reinforcing plates used, thus reducing costs.

[0005] However, the structure has low bearing capacity, making it difficult to meet the requirements for earthquake and wind resistance design. Utility Model Content

[0006] The purpose of this utility model is to provide a steel beam joint structure for concrete shear walls to solve the problem mentioned in the background art of low structural bearing capacity, which makes it difficult to meet the requirements of seismic and wind resistance design.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel beam node structure for a concrete shear wall, comprising a shear wall and a steel beam, wherein the steel beam is installed on the right side of the shear wall and an installation unit is provided at the left end of the steel beam;

[0008] The installation unit includes an end plate, an upper flange plate stiffener, a lower flange plate stiffener, and a shear key. The end plate is fixedly connected to the left end of the steel beam, the upper flange plate stiffener is fixedly connected to the top of the steel beam, the lower flange plate stiffener is fixedly connected to the bottom of the steel beam, and the shear key is fixedly connected to the left end of the steel beam. The lateral force applied to the steel beam is transmitted to the web of the steel beam through the upper and lower flange plate stiffeners, and the force on the steel beam is distributed into the shear wall through the shear key, reducing the deformation of the steel beam, further improving the load-bearing capacity of the steel beam, and enhancing the structural stability.

[0009] Preferably, the shear key and the steel beam are integrated into a single structure, and the shear key has a threaded hole on its front side, which allows for fast assembly and easy quality assurance.

[0010] Preferably, the upper flange plate stiffener and the steel beam, as well as the lower flange plate stiffener and the steel beam, are fixedly connected by welding. The stiffener disperses the force on the steel beam, making the device more stable.

[0011] Preferably, the shear wall has an installation groove on its right side, and the shear key is installed inside the installation groove. The shear wall has a threaded hole on its front side that matches the threaded hole on the shear key. The shear wall and the shear key are connected by bolts through the threaded hole, which facilitates the maintenance and replacement of the steel beam. At the same time, this connection method also ensures the stability and safety of the shear key during operation.

[0012] Preferably, the shear wall has an auxiliary threaded hole on its right side, and the end plate has a matching threaded hole on its left side. The end plate and the shear wall are connected by bolts through the auxiliary threaded hole, which improves the quality and stability of the assembly connection between the shear wall and the steel beam.

[0013] Preferably, the shear key is made of QGJC steel plate, which has advantages such as high strength, good toughness, weldability, resistance to low-temperature impact and corrosion resistance.

[0014] Preferably, the bolts used to connect the various components are made of CrMo, which has good strength and toughness and is suitable for manufacturing high-strength bolts that meet high requirements and withstand greater pressure. It is widely used in key connection parts in the construction industry.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The steel beam joint structure of this concrete shear wall transmits the lateral force applied to the steel beam to the web of the steel beam through the upper flange plate stiffeners and the lower flange plate stiffeners. The shear keys disperse the force on the steel beam into the shear wall, reducing the deformation of the steel beam, further improving the load-bearing capacity of the steel beam, and enhancing the structural stability.

[0017] 2. The steel beam joint structure of this concrete shear wall extensively uses bolt and thread connections, which speeds up the assembly process and improves the quality and stability of the assembly connection between the shear wall and the steel beam. Attached Figure Description

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] Example 1: A steel beam joint structure for a concrete shear wall, comprising a shear wall 1 and a steel beam 2, wherein the steel beam 2 is installed on the right side of the shear wall 1 and an installation unit is provided at the left end of the steel beam 2;

[0026] The installation unit includes an end plate 3, an upper flange plate stiffener 4, a lower flange plate stiffener 401, and a shear key 5. The end plate 3 is fixedly connected to the left end of the steel beam 2, the upper flange plate stiffener 4 is fixedly connected to the upper part of the steel beam 2, the lower flange plate stiffener 401 is fixedly connected to the lower part of the steel beam 2, and the shear key 5 is fixedly connected to the left end of the steel beam 2.

[0027] The shear key 5 is made of Q345GJC steel plate, and the bolts used to connect the components are made of 35CrMo.

[0028] In this embodiment, the lateral force applied to the steel beam 2 is transmitted to the web of the steel beam 2 through the upper flange plate stiffener 4 and the lower flange plate stiffener 401. The force on the steel beam 2 is dispersed into the shear wall 1 through the shear key 5, reducing the deformation of the steel beam 2, further improving the load-bearing capacity of the steel beam 2, and improving the structural stability. Using high-strength steel as the material can extend the service life of the device and reduce the occurrence of accidents.

[0029] Example 2: Based on Example 1, the shear key 5 and the steel beam 2 are integrated into a single structure. The shear key 5 has a threaded hole on its front side. The upper flange plate stiffener 4 and the steel beam 2, as well as the lower flange plate stiffener 401 and the steel beam 2, are fixedly connected by welding. The shear wall 1 has an installation groove 101 on its right side, and the shear key 5 is installed inside the installation groove 101. The shear wall 1 has a threaded hole on its front side that matches the threaded hole on the shear key 5. The shear wall 1 and the shear key 5 are connected by bolts through the threaded hole. The shear wall 1 has an auxiliary threaded hole 102 on its right side, and the end plate 3 has a matching threaded hole on its left side. The end plate 3 and the shear wall 1 are connected by bolts through the auxiliary threaded hole 102.

[0030] In this embodiment, bolt thread connections are widely used to speed up the assembly process and improve the quality and stability of the assembly connection between the shear wall 1 and the steel beam 2.

[0031] Working principle: The lateral force applied to the steel beam 2 is transmitted to the web of the steel beam 2 through the upper flange stiffener 4 and the lower flange stiffener 401. The shear key 5 disperses the force on the steel beam 2 into the shear wall 1, reducing deformation of the steel beam 2 and further enhancing its load-bearing capacity and structural stability. The use of high-strength steel extends the service life of the device and reduces the occurrence of accidents. The extensive use of bolt and thread connections speeds up assembly and improves the quality and stability of the assembly connection between the shear wall 1 and the steel beam 2.
