Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, and in particular to a prefabricated shear wall vertical connection structure. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Because it employs standardized design, factory production, assembly-line construction, information management, and intelligent applications, it represents modern industrialized production methods. Vertical connections of shear walls are a key aspect of structural connections in high-rise prefabricated buildings; their installation accuracy and construction efficiency directly affect project quality and construction schedule.

[0003] In existing technologies, vertical connections mainly include sleeve grouting connections, grout anchoring connections, and steel bar lap welding connections. These methods suffer from problems such as long construction cycles, complex external support structures, and high positioning difficulty, resulting in low construction efficiency and failing to meet the development trend of prefabricated buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated shear wall vertical connection structure, which is simple in structure, easy to position, and can effectively improve the construction efficiency and safety of the vertical connection of the prefabricated shear wall structure.

[0005] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0006] A prefabricated vertical connection structure for shear walls includes an upper shear wall and a lower shear wall. H-beams are vertically installed along the horizontal edges of both the upper and lower shear walls. A steel plate is fixedly installed at the top of the lower shear wall. A steel connector is horizontally installed between the upper and lower shear walls. The lower end of the H-beam is fixedly connected to the upper part of the steel connector, and the steel plate is fixedly connected to the lower part of the steel connector. The vertically installed H-beams along the horizontal edges of the upper and lower shear walls, with the lower end of the H-beams fixed to the upper part of the steel connector and the steel plate fixed to the lower part of the steel connector, effectively increase the shear resistance and energy dissipation capacity of the shear walls. The structure is simple, easy to position, and reduces the installation difficulty of the vertical connection structure for shear walls, effectively improving the construction efficiency and safety of the vertical connection of prefabricated shear wall structures.

[0007] Furthermore, the steel connector is an H-beam or an I-beam, comprising a horizontally arranged upper flange and a lower flange. The lower end of the H-beam is welded and fixed to the upper flange, and the steel plate is fixedly connected to the lower flange by fasteners. This method of fixing the lower end of the H-beam to the plane of the upper flange and the steel plate to the plane of the lower flange further reduces the difficulty of installing and positioning the upper and lower shear walls, and increases the stability and safety of the connection between the upper and lower shear walls and the steel connector.

[0008] Furthermore, the steel connector also includes a web vertically disposed between the upper and lower flanges, the web having multiple through holes. The multiple through holes on the web of the steel connector allow concrete to effectively penetrate and permeate both sides of the connector, increasing the fusion strength between the concrete and the steel, thus effectively improving the stability of the vertical connection between the upper and lower shear walls and enhancing the shear resistance of the shear walls.

[0009] Furthermore, the lower shear wall is vertically equipped with multiple anchor rods. The ends of the anchor rods facing the upper shear wall penetrate the steel plate and the lower flange. The steel connectors are fixedly connected to the steel plate by the anchor rods and nuts. By using anchor rods to penetrate the steel plate (lower flange), the construction difficulty is reduced, while also improving installation accuracy and increasing the energy dissipation capacity of the shear wall.

[0010] Furthermore, the upper and lower shear walls are provided with horizontal and longitudinal reinforcements, and the longitudinal reinforcements are welded and fixed to the outer surface of the flange plate of the H-beam. By welding and fixing the longitudinal reinforcements to the flange plate of the H-beam at the edge of the shear wall, the overall height of the shear wall can be increased, thereby improving the shear resistance of the shear wall.

[0011] Furthermore, reinforcing ribs are provided between the flanges of the H-beam, and these ribs are distributed on both sides of the web of the H-beam. The addition of these reinforcing ribs further increases the rigidity of the H-beam, enhances its support for the shear wall, and improves its overall shear resistance.

[0012] Furthermore, the ends of the longitudinal reinforcement bars within the upper shear wall that face the steel connectors are welded and fixed to the plane of the upper flange. This welding of the longitudinal reinforcement bars to the plane of the upper flange facilitates construction and further improves construction efficiency.

[0013] Furthermore, the ends of the longitudinal reinforcement bars within the lower shear wall facing the steel plate are welded and fixed to the steel plate. This welding of the longitudinal reinforcement bars to the steel plate plane facilitates construction and further improves construction efficiency. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0021] like Figure 1-4As shown, one embodiment of this utility model relates to a prefabricated shear wall vertical connection structure, including an upper shear wall 10 and a lower shear wall 20. H-beams 40 are vertically provided on the horizontal edges of the upper shear wall 10 and the lower shear wall 20. A steel plate 60 is fixedly provided on the top of the lower shear wall 20. A steel connector 50 is horizontally provided between the upper shear wall 10 and the lower shear wall 20. The lower end of the H-beam 40 is fixedly connected to the upper part of the steel connector 50, and the steel plate 60 is fixedly connected to the lower part of the steel connector 50. The use of H-beams 40 vertically installed along the horizontal edges of the upper shear wall 10 and the lower shear wall 20, with the lower end of the H-beams 40 fixedly connected to the upper part of the steel connector 50 and the steel plate 60 fixedly connected to the lower part of the steel connector 50, effectively increases the shear resistance and energy dissipation capacity of the shear wall. The structure is simple, easy to position, and reduces the installation difficulty of the vertical connection structure of the shear wall, effectively improving the construction efficiency and safety of the vertical connection of the prefabricated shear wall structure.

[0022] In one embodiment, a prefabricated shear wall vertical connection structure is provided, wherein the steel connector 50 is an H-beam or an I-beam. The steel connector 50 includes an upper flange 51 and a lower flange 52, and a web 53 vertically disposed between the upper flange 51 and the lower flange 52. The lower end of the H-beam 40 is welded and fixed to the plane of the upper flange 51, and the steel plate 60 is fixedly connected to the lower flange 52 by fasteners. By fixing the lower end of the H-beam 40 to the plane of the upper flange 51 and the steel plate 60 to the plane of the lower flange 52, the difficulty of installing and positioning the upper shear wall 10 and the lower shear wall 20 is further reduced, and the connection stability and safety between the upper shear wall 10, the lower shear wall 20 and the steel connector 50 are increased. Preferably, the web 53 is provided with a plurality of through holes 54. When grouting is performed, concrete can pass through the through holes 54 and overflow to both sides of the web 53, increasing the strength of the fusion between the concrete and the steel section, effectively improving the stability of the vertical connection between the upper shear wall 10 and the lower shear wall 20, and enhancing the shear resistance of the shear wall.

[0023] In one embodiment, a prefabricated shear wall vertical connection structure is provided, wherein the upper shear wall 10 and the lower shear wall 20 are provided with horizontal ribs 12 and longitudinal ribs 11, and the longitudinal ribs 11 are welded and fixed to the outer surface of the flange plate 41 of the H-beam 40. By welding and fixing the longitudinal ribs 11 to the flange plate 41 of the H-beam 40 at the edge of the shear wall, the overall height of the shear wall can be increased, thereby improving the shear resistance of the shear wall. Preferably, reinforcing ribs 42 are provided between the flange plates 41 of the H-beam 40, and the reinforcing ribs 42 are distributed on both sides of the waist 43 of the H-beam 40. Preferably, the reinforcing ribs 42 are symmetrically distributed on both sides of the waist 43 of the H-beam 40. By setting the reinforcing ribs 42, the rigidity of the H-beam 40 is further increased, the support for the shear wall is increased, and the overall shear resistance is improved. In one exemplary example, the ends of the longitudinal reinforcement 11 in the upper shear wall 10 facing the steel connector 50 are welded and fixed to the plane of the upper flange 51. The arrangement of welding the longitudinal reinforcement 11 to the plane of the upper flange 51 facilitates construction and helps to further improve construction efficiency. The ends of the longitudinal reinforcement 11 in the lower shear wall 20 facing the steel plate 60 are welded and fixed to the steel plate 60. The arrangement of welding the longitudinal reinforcement 11 to the plane of the steel plate 60 facilitates construction and helps to further improve construction efficiency.

[0024] In one embodiment, a prefabricated shear wall vertical connection structure is provided, wherein the lower shear wall 20 is vertically provided with multiple anchor rods 30. The ends of the anchor rods 30 facing the upper shear wall 10 penetrate the steel plate 60 and the lower flange 52. The steel connector 50 is fixedly connected to the steel plate 60 by the engagement of the anchor rods 30 and nuts 31. Specifically, the ends of the anchor rods 30 facing the upper shear wall 10 are threaded. Nuts 31 are sleeved on the ends of the anchor rods 30 away from the lower shear wall 20, and the nuts 31 and anchor rods 30 are fastened by the threaded engagement, thus fixing the steel connector 50 to the steel plate 60. The setting of anchor rods 30 penetrating the steel plate 60 and the lower flange 52 and being fixedly connected by threads reduces the construction difficulty, while also improving installation accuracy and increasing the energy dissipation capacity of the shear wall.

[0025] This utility model provides a prefabricated shear wall vertical connection structure. By vertically installing H-beams along the horizontal edges of the upper and lower shear walls, and fixing the lower ends of the H-beams to the upper parts of the steel connectors and the steel plates to the lower parts of the steel connectors, the shear wall's shear resistance and energy dissipation capacity are effectively increased. The structure is simple, positioning is convenient, and the installation difficulty of the vertical connection structure is reduced, effectively improving the construction efficiency and safety of the prefabricated shear wall structure's vertical connection. By selecting H-beams or I-beams as steel connectors, the ends of the H-beams and longitudinal reinforcements of the upper shear wall are fixedly positioned to the plane of the steel connectors, and the steel plates of the lower shear wall are fixedly abutted against the plane of the steel connectors. This effectively reduces positioning difficulty, improves the installation accuracy of the upper and lower shear walls, increases construction efficiency, and enhances the connection stability and safety between the upper and lower shear walls and the steel connectors.
