Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of steel structure connection technology. Specifically, it relates to a beam-wall joint structure with an external steel plate shear wall. Background Technology

[0002] A steel plate composite shear wall is a steel plate shear wall composed of steel plates on both sides and concrete filling in the middle, working together to combine the properties of both steel and concrete and leverage the advantages of each. Currently, the commonly used rigid connection node is to set transverse diaphragms at the upper and lower flanges of the steel beam. The construction of the steel plate shear wall generally involves first constructing the steel plate wall and then pouring self-compacting concrete inside. To ensure the quality of the concrete pouring, grouting holes and vent holes need to be opened in the transverse diaphragms. However, this weakens the strength of the diaphragms and affects the strength of the joint. If the grouting holes in the diaphragms are too small, it will also affect the quality of the concrete pouring. This will affect the performance of the steel plate shear wall and thus the structural safety.

[0003] Currently, a steel beam is fixed to the outside of the steel-concrete composite shear wall by means of a fixed single-sided bolt penetrating through it. When using a node connection, the steel beam is fixed to the outside of the fixed single-sided bolt by means of stiffening ribs, inner plates and auxiliary threaded holes. The T-shaped stiffening ribs are set inside the steel-concrete composite shear wall.

[0004] However, when the wall splicing joint is at half a story height, it is difficult to position the stiffening ribs at the floor level, increasing the construction difficulty. Moreover, relying solely on bolts to resist the internal forces of the beam cannot achieve a rigid joint. Therefore, a beam-wall joint structure with an external steel plate shear wall is designed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a beam-wall joint structure with an outer steel plate shear wall.

[0020] like Figure 1-4As shown, this utility model provides a beam-wall joint structure with an external steel plate shear wall, including a steel plate composite shear wall 1. The steel plate composite shear wall 1 includes a hidden column 1a at its end and steel plates 1b on both sides of the wall. The hidden column 1a is a rectangular steel tube concrete component. The steel plate composite shear wall 1 is connected to the hidden column 1a and the steel plates 1b on both sides of the wall by welds. An H-shaped steel beam 7 is provided on one side of the hidden column 1a. An upper connecting plate 2 and a lower connecting plate 3 are respectively provided between the H-shaped steel beam 7 and the hidden column 1a. A transverse reinforcing rib 4 is provided on the bottom side of the upper connecting plate 2. A cover plate 9 is provided between the H-shaped steel beam 7 and the upper connecting plate 2 and the lower connecting plate 3. The end of the cover plate 9 abuts against the hidden column 1a.

[0021] Furthermore, in this embodiment, the lower connecting plate 3 corresponds to the lower flange of the H-beam 7, and the lower connecting plate 3 penetrates the concealed column 1a and connects with the slot in the steel plate 1b. The lower connecting plate 3 directly passes through the concealed column 1a and is welded to the slot in the steel plate 1b, which improves the stability of the installation of the lower connecting plate 3. The lower connecting plate 3 extends 50mm into the steel plate 1b and protrudes 30mm from the outside of the steel plate combined shear wall 1 on both sides. The end of the lower connecting plate 3 is chamfered to transition to the same width as the flange of the H-beam 7.

[0022] In this embodiment, the upper connecting plate 2 corresponds to the upper flange of the H-shaped steel beam 7. A rectangular hole is provided at the center of the upper connecting plate 2 for the hidden column 1a to pass through. One side of the upper connecting plate 2 is inserted into the groove of the steel plate 1b and welded to the steel plate 1b. The rectangular hole allows the upper connecting plate 2 to be fitted onto the outside of the hidden column 1a and connected to the steel plate 1b. The size of the upper connecting plate 2 is determined according to the outward extension width. The upper connecting plate 2 extends 50mm into the steel plate 1b.

[0023] In this embodiment, both the upper connecting plate 2 and the lower connecting plate 3 are welded to the hidden column 1a and the steel plate 1b, and the upper and lower connecting plates 3 are fixed on the hidden column 1a and the steel plate 1b by welding.

[0024] In this embodiment, transverse reinforcing ribs 4 are provided on both sides of the connection between the upper connecting plate 2 and the steel plate combined shear wall 1. The transverse reinforcing ribs 4 are welded to the upper connecting plate 2 and the steel plate combined shear wall 1. The strength of the upper connecting plate 2 is enhanced by the transverse reinforcing ribs 4, and the length of the transverse reinforcing ribs 4 is consistent with the length of the upper connecting plate 2.

[0025] In this embodiment, the upper connecting plate 2 is 50-100mm wider than the lower connecting plate 3. Its function is to diffuse the tensile force transmitted from the upper flange of the H-beam 7 to the steel plate and concrete, so as to prevent the weld and steel plate 1b from being torn locally. The lower connecting plate 3 only needs to apply pressure to the lower flange, so it does not need to be so wide, thus saving materials.

[0026] In this embodiment, the cover plate 9 is welded to the hidden column 1a, the upper connecting plate 2, the lower connecting plate 3, and the H-shaped steel beam 7 respectively. The cover plate 9 covers the connection between the upper connecting plate 2 and the lower connecting plate 3 and the H-shaped steel beam 7. The outer end of the cover plate 9 is designed with a chamfer. The chamfer at the end of the cover plate 9 is because the end does not need too much steel plate 1b, saving materials. The cover plate 9 is used to improve the strength of the joint, realize the strong joint and weak component of the seismic requirements, and make the good ductility of the steel structure come into play.

[0027] In this embodiment, a vertical connecting plate 5 is provided between the upper connecting plate 2 and the lower connecting plate 3. The vertical connecting plate 5 corresponds to the web of the H-beam 7. A web connecting plate 6 is provided between the H-beam 7 and the vertical connecting plate 5. The upper and lower connecting plates are connected together by the vertical connecting plate 5.

[0028] In this embodiment, the vertical connecting plate 5 is welded to the upper connecting plate 2, the lower connecting plate 3 and the hidden column 1a. The web connecting plate 6 is connected to the web of the vertical connecting plate 5 and the H-beam 7 by high-strength bolts 8. The vertical connecting plate 5 and the H-beam 7 are connected together by the web connecting plate 6.

[0029] In this embodiment, the lower connecting plate 3 is provided with an elongated oval injection hole 3a and two ventilation holes 3b in the connection area with the hidden column 1a. Self-compacting concrete is poured into the hidden column 1a and between the steel plate 1b. Since there is no inner partition in the upper connecting plate 2, the surface of the lower connecting plate 3 is provided with an elongated oval injection hole 3a and two ventilation holes 3b, which does not affect the concrete pouring.

[0030] Specifically, when assembling the steel plate composite shear wall 1 at the nodes, each component is prefabricated in the factory according to the construction requirements. The center line, edge line and elevation control points of the steel plate composite shear wall 1 are marked on the floor installation baseline. The steel plate composite shear wall 1 is vertically hoisted to the installation position using a tower crane. The bottom is fixed with temporary limiting angle steel, and the top is straightened with guy ropes. The bottom of the wall panel is connected to the foundation or the lower wall panel with high-strength bolts and slit welds. H-beam 7 is hoisted to the design elevation, with the center of the web aligned with the vertical connecting plate 5. The web of H-beam 7 is then connected to the vertical connecting plate 5 using high-strength bolts via the web connecting plate 6. The torque value is re-verified according to the specifications. The horizontality, elevation, and end gap of the steel beam are checked. Before the cover plate 9 is closed, the upper connecting plate 2 and the upper flange of the steel beam, and the lower connecting plate 3 and the lower flange of the steel beam are welded. After confirming that everything is correct, the process of closing the cover plate 9 begins. Cut the cover plate 9 on-site according to the actual size, make a 30° chamfer on the outer end, and grind it smooth. The cover plate 9 covers the junction of the upper flange and the upper connecting plate 2, the lower flange and the lower connecting plate 3, the web connecting plate 6 and the vertical connecting plate 5, and weld them. After welding, remove the slag, grind, and apply epoxy thick paint that is compatible with the original anti-corrosion system. Insert grouting pipes into the elongated grouting holes 3a at the top of the hidden column 1a and the lower connecting plate 3, and continuously inject grout from top to bottom until the design elevation is reached. After curing and demolding, re-inspect all welds.
