Technical Field

[0001] This utility model relates to the field of building structure engineering, specifically a steel box beam connection structure for adding an elevator to a building and the original building structure. Background Technology

[0002] Traditional methods often involve directly reinforcing concrete beams or using post-anchoring technology with small-diameter anchors or steel bars, which results in poor connection performance and often causes significant damage to the original structure, reducing its load-bearing capacity. Therefore, a steel box girder structure for elevator installation in buildings is needed to connect the building to the original main structure.

[0003] When installing elevators in existing residential buildings, problems often arise when the walls or beams are not thick enough, such as chemical anchors and rebar not meeting the anchoring requirements, and the connection between the box girder and the main structure is not easy to install. Furthermore, the installation of elevators in existing residential buildings often affects the overall structural rigidity of the main building. Therefore, there is an urgent need for a steel box girder connection structure between the elevator installation and the original building structure. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a connection structure between the steel box girder for elevator installation in a building and the original building structure, so as to solve the problems that existing devices often fail to meet the anchoring requirements of chemical anchors and rebar, and the connection between the box girder and the main structure is difficult to install. Furthermore, the installation of elevators in existing residential buildings often affects the overall structural rigidity of the main building.

[0006] An end plate is installed at the end of the box girder. A first connecting plate is installed on the outer wall of the end plate. A second connecting plate is installed on the outer wall of the steel plate. A stainless steel bolt is installed on the inner wall of the second connecting plate. A second nut is installed on the outer wall of the stainless steel bolt. A stiffening plate is installed on the outer wall of the steel plate.

[0007] Preferably, the inner wall of the steel plate is perforated, and both the inner wall of the steel plate and the inner wall of the concrete beam are threaded.

[0008] Preferably, the equivalent screw penetrates the interior of the concrete beam and the steel plate, and the steel plate is threadedly fixed to the concrete beam.

[0009] Preferably, the box girder is welded to the end plate, and the end plate is welded to the first connecting plate.

[0010] Preferably, the first connecting plate is symmetrically arranged with respect to the central axis of the end plate, and the inner walls of both the first connecting plate and the second connecting plate are threaded.

[0011] Preferably, the second connecting plate is symmetrically arranged around the central axis of the steel plate, and the second connecting plate is threadedly fixed to the first connecting plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figure 1-3A steel box girder for elevator installation in a building is connected to the original building structure. The structure includes a concrete beam 1, a steel plate 2 installed on the side wall of the concrete beam 1, an elongated hole 3 on the inner wall of the concrete beam 1, an equivalent screw 4 installed on the inner wall of the concrete beam 1, and a first nut 5 installed on the outer wall of the equivalent screw 4. The equivalent screw 4 penetrates the interior of both the concrete beam 1 and the steel plate 2, and the steel plate 2 is threadedly fixed to the concrete beam 1. The box girder 6 is welded to an end plate 7, and the end plate 7 is welded to a first connecting plate 8. When using the device, the steel plate 2 is fixed to the concrete beam 1 by using the equivalent screw 4 and the first nut 5, satisfying anchorage while reinforcing the bending capacity of the concrete beam 1. Furthermore, the addition of the elongated hole 3 ensures that the concrete beam 1 only bears vertical shear force, effectively preventing the generation of eccentric bending moments.

[0022] Please see Figure 1-3 A steel box girder for elevator installation in a building is connected to the original building structure. The box girder 6 has an end plate 7 installed at its end. A first connecting plate 8 is installed on the outer wall of the end plate 7. A second connecting plate 9 is installed on the outer wall of a steel plate 2. Stainless steel bolts 10 are installed on the inner wall of the second connecting plate 9. A second nut 11 is installed on the outer wall of the stainless steel bolts 10. A stiffening plate 12 is installed on the outer wall of the steel plate 2. The box girder 6 is welded to the end plate 7, and the end plate 7 is welded to the first connecting plate 8. The first connecting plate 8 is symmetrically arranged about the central axis of the end plate 7. Both the inner walls of the first connecting plate 8 and the second connecting plate 9 are threaded. The second connecting plate 9 is symmetrically arranged about the central axis of the steel plate 2 and is threadedly fixed to the first connecting plate 8. In use, the box girder 6 is connected to the concrete beam 1 using the stainless steel bolts 10 and the second nut 11. The stiffening plate 12 enhances the stability of the connection, simplifying the connection method and reducing construction costs.

[0023] Working principle: In use, firstly, place the steel plate 2 on the side wall of the concrete beam 1, align the holes on the steel plate 2 with the elongated holes 3 on the concrete beam 1, then insert the equivalent screw 4 into the elongated holes 3 and the holes on the steel plate 2 for connection, and then fix it with the first nut 5, which strengthens the bending bearing capacity of the concrete beam 1. At the same time, the connection uses a vertical elongated hole 3 to avoid additional external forces on the concrete beam 1 due to irregular settlement. Then, weld the end plate 7 to the end of the box beam 6, and then weld the first connecting plate 8 to the end plate 7. Align the holes on the second connecting plate 9 on the steel plate 2 with the holes on the first connecting plate 8, then insert the stainless steel bolts 10 into the holes on the first connecting plate 8 and the second connecting plate 9 for fixing, thus fixing the concrete beam 1 and the box beam 6. Then, install the stiffening plate 12 at the connection point for reinforcement and stability. This greatly reduces construction costs, simplifies construction procedures, and avoids subsequent safety hazards caused by structural changes. This completes the use of the device.
