Description

Technical Field

[0001] This utility model relates to the field of construction technology of frame shear wall structure buildings, specifically a connection node between structural columns and ring beams and frame shear wall structures in high seismic zones. Background Technology

[0002] In today's society, building design in high-seismic-risk areas has become a field of great concern. With the increasing frequency of natural disasters, higher demands are being placed on the seismic performance of building structures. Traditional building design focuses on the strength and stability of buildings, but the horizontal loads during earthquakes pose a significant challenge. Therefore, seismic design has gradually become an important research direction in the field of architecture.

[0003] Frame-shear wall structures are a common seismic design scheme widely used in buildings in high-seismic-risk areas. The frame structure can withstand vertical loads, while the shear wall effectively resists horizontal seismic forces, together forming a stable structural form. Through proper design and optimization, frame-shear wall structures can provide excellent seismic performance, offering effective protection for buildings during earthquakes. Masonry walls are commonly used in buildings as external enclosure structures and internal space partitions. To improve the integrity, stability, and seismic performance of the masonry, concrete structural columns and ring beams are required. Currently, the traditional method for connecting structural columns, ring beams, and the main frame-shear wall structure is to anchor the vertical reinforcement of the structural columns into the frame beams, or the horizontal reinforcement of the ring beams into the frame columns or shear walls. Under high seismic intensity, these connection nodes may fail before the main structure, structural columns, and ring beam components, increasing the risk of building collapse under seismic action. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to provide a connection node between structural columns and ring beams and frame shear wall structures in high seismic zones. While retaining the role of structural columns and ring beams in strengthening the integrity, stability and seismic performance of masonry, it introduces damping materials and a new connection node structure. Through this design, the ductility at the connection node is improved, and seismic energy can be dissipated more effectively during earthquakes, thereby improving the seismic performance of the connection node and masonry, and providing a more reliable guarantee for the safety and stability of buildings during earthquakes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is:

[0006] A connection node between a structural column and a ring beam and a frame shear wall structure in a high seismic zone includes a masonry structure consisting of masonry, a concrete ring beam, and a concrete structural column, and a main structure consisting of a frame beam and a frame column or shear wall. A transverse connection structure is provided between the concrete ring beam and the frame column or shear wall, and a vertical connection structure is provided between the concrete structural column and the frame beam.

[0007] Preferably, the transverse connection structure includes transverse reinforcing bars, one end of which is embedded in the frame column or shear wall, and a transverse PVC sleeve is installed in the concrete ring beam, with the other end of the transverse reinforcing bars inserted into the transverse PVC sleeve.

[0008] Preferably, the concrete ring beam is provided with ring beam support reinforcement and ring beam stirrups.

[0009] Preferably, a first buffer layer is provided between the concrete ring beam and the frame column or shear wall, and the thickness of the first buffer layer is 2-3cm.

[0010] Preferably, the transverse PVC sleeve is made of rubber or polyurethane foam, and the diameter of the transverse PVC sleeve is ±5mm of the transverse steel bar size.

[0011] Preferably, the vertical connection structure includes vertical reinforcing bars, one end of which is embedded in the frame beam, and a vertical PVC sleeve is installed in the concrete structural column, with the other end of the vertical reinforcing bar inserted into the vertical PVC sleeve embedded in the concrete structural column.

[0012] Preferably, the concrete structural column is provided with vertical reinforcing bars and stirrups.

[0013] Preferably, a second buffer layer is provided between the concrete structural column and the frame beam, and the thickness of the second buffer layer is 2-3cm.

[0014] Preferably, the vertical PVC sleeve is made of rubber or polyurethane foam, and the diameter of the vertical PVC sleeve is ±5mm of the vertical steel bar 701.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model ingeniously utilizes the frame shear wall (frame column or shear wall) structure, concrete structural columns, ring beams, and horizontal and vertical connection structures to construct a connection node suitable for high seismic intensity zones. On the one hand, it ensures the integrity and stability of the masonry, and on the other hand, it effectively improves the seismic performance of the connection node between the structural columns and ring beams and the frame shear wall structure.

[0017] 2. This utility model utilizes the lateral and vertical connection structure of frame beams and concrete structural columns and ring beams, as well as a buffer layer. Under earthquakes, there can be a small lateral displacement between the top of the structural column and the frame beam, and a small misalignment between the end of the ring beam and the frame column or shear wall, thereby mitigating the seismic action on the masonry. At the same time, this structure improves the ductility at the connection nodes, which can also greatly reduce the possibility of connection node failure under strong earthquakes.

[0018] 3. This utility model has a novel, simple and practical structure, low material cost, and convenient construction. Attached Figure Description

[0028] Combination Figure 1 — Figure 5 As shown, this utility model relates to a connection node between a structural column and a ring beam and a frame shear wall structure in a high seismic zone.

A transverse PVC sleeve 8 is set in the concrete ring beam 2. The other end of the transverse steel bar 601 is inserted into the transverse PVC sleeve 8.

[0030] The vertical connection structure 7 includes a vertical steel bar 701. One end of the vertical steel bar 701 is embedded in the frame beam 4. A vertical PVC sleeve 81 is installed in the concrete structural column 3.

[0032] The concrete structural column 3 is provided with vertical reinforcing bars 301 and stirrups 302.

[0033] This scheme utilizes transverse connection structure 6 and vertical connection structure 7 to strengthen the connection between masonry 1 and frame column shear wall 5. This ensures the integrity and stability of the masonry while improving the seismic performance of the connection nodes between structural columns and ring beams and frame shear wall structures in high seismic zones. In transverse connection structure 6, the transverse reinforcement 601 is positioned at the center of the concrete ring beam 2, with its embedded length in the frame column or shear wall 5 consistent with its length within the ring beam. In vertical connection structure 7, the vertical reinforcement 701 is positioned at the center of the concrete structural column 3, with its embedded length in the frame beam consistent with its length within the structural column. The portion embedded in the frame beam is fixed to the internal reinforcing cage using tie wire. A buffer rubber pad is placed between the frame beam and the top of the structural column, and also between the frame column or shear wall and the end of the ring beam. The rubber pad has openings at the reinforcement locations, with the opening diameter matching the diameter of the vertical anchor reinforcement.

[0034] Preferably, a first buffer layer 9 is provided between the concrete ring beam 2 and the frame column or shear wall 5, and the thickness of the first buffer layer 9 is 2-3cm.

[0035] Preferably, the transverse PVC sleeve 8 is made of rubber or polyurethane foam, and the diameter of the transverse PVC sleeve 8 is ±5mm of the transverse steel bar 601.

[0037] Preferably, the vertical PVC sleeve 81 is made of rubber or polyurethane foam, and the diameter of the vertical PVC sleeve 81 is ±5mm of the vertical reinforcing bar 701.

[0038] Rubber or polyurethane foam materials can more effectively absorb and dampen the energy generated by earthquakes, reducing structural stress.

[0039] During construction, prepare the necessary materials and equipment. Pre-embed the horizontal reinforcing bars 601 in the frame columns or shear walls 5, and the vertical reinforcing bars 701 in the frame beams 4, then pour the main structural concrete. Next, make holes in the first buffer layer 9 and the second buffer layer 91 according to the positions of the horizontal reinforcing bars 601 and 701. Then, correctly fit the first buffer layer 9 and the second buffer layer 91 onto the horizontal reinforcing bars 601 and 701. Then, insert the horizontal PVC sleeve 8 and the vertical PVC sleeve 81 into the exposed ends of the horizontal reinforcing bars 601 and 701 respectively, and perform preliminary fixing. Finally, carry out masonry construction, pour the concrete ring beam and structural columns. Throughout the construction process, pay attention to the accuracy of the positions of the horizontal reinforcing bars 601 and 701, and the firm connection of the buffer layers and sleeves to ensure that the construction quality meets the requirements.
