They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0021] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.
[0022] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.
[0023] refer to Figure 1 , this embodiment provides a main beam-shear wall reinforcement structure, which includes a beam reinforcement 1, a main beam 2, a shear wall 3 and a fixed steel plate 5. The main beam 2 is arranged on the side of the shear wall 3, and the main beam 2 and the shear wall 3 are vertically arranged. At the same time, the fixed steel plate 5 is arranged on the side of the shear wall 3 away from the main beam 2, and the fixed steel plate 5 and the side of the shear wall 3 are fixedly connected by a screw 4, thereby helping to enhance the connection strength between the main beam 2 and the shear wall 3, thereby improving the seismic performance of the overall structure. Furthermore, the fixed steel plate 5 and the main beam 2 are fixedly connected by the beam reinforcement 1, so that the connection strength between the main beam 2 and the shear wall 3 can be further strengthened, that is, by fixing the beam reinforcement 1, the rigidity of the entire structure can be further improved, and the deformation caused by vibration can be reduced.
[0024] In this embodiment, the beam reinforcement 1 is set to be L-shaped, wherein the L-shaped corner of the beam reinforcement 1 is set at the upper end of the fixed steel plate 5, and at the same time, the beam reinforcement 1 and the outer side of the fixed steel plate 5 are fixedly connected by welding, so that the beam reinforcement 1 can better support and connect the main beam 2 and the fixed steel plate 5, further enhancing the overall stability of the structure.
[0025] Furthermore, to allow the main beam in this embodiment to move under the influence of temperature changes or other factors without damaging the structure, an expansion joint 6 is provided between the shear wall 3 and the fixed steel plate 5. The width of the expansion joint 6 is set to 2mm-3mm. A rubber gasket is also installed inside the expansion joint 6, and the end of the screw 4 passes through the expansion joint 6. In other words, the placement of the rubber gasket inside the expansion joint 6 can effectively absorb and buffer the stress generated by this displacement, thereby protecting the structure from damage.
[0026] In this embodiment, cover plates 7 are provided at both ends of the fixed steel plate 5. One end of the cover plate 7 fits against the side of the shear wall 3, and the cover plate 7 is fixedly connected to the end of the fixed steel plate 5 by bolts 8. Furthermore, a plurality of pouring holes are evenly arranged on the fixed steel plate 5, each of which penetrates the fixed steel plate 5 and the expansion joint 6, and each of which is filled with concrete. In other words, the provision of the cover plate 7 increases the contact area between the shear wall 3 and the fixed steel plate 5, thereby improving the stability of the connection. At the same time, the provision of multiple pouring holes and concrete, that is, injecting concrete into the gap between the shear wall 3 and the fixed steel plate 5 through the pouring holes, allows the two to be tightly combined, further improving the overall strength and stability of the structure.
