Description

Technical Field

[0001] This utility model relates to a prefabricated shear wall structure with horizontal joints and vertical connections, and relates to the field of building structures. Background Technology

[0002] With the development of prefabricated building technology, prefabricated shear walls, as an important structural unit, have been widely used in modern high-rise buildings, industrial buildings, and other projects. Existing connection methods for prefabricated shear walls mainly include sleeve grouting connections, grout-anchored lap connections, and bolt connections.

[0003] While these connection methods can ensure the stability of shear walls to a certain extent, the following problems still exist:

[0004] (1) Incomplete grouting: Due to improper construction operations or structural problems, the flow of grouting material is often obstructed, resulting in voids in the dark cavity at the connection, which reduces the shear strength and stability of the shear wall.

[0005] (2) High construction cost and construction complexity: Existing common connection methods are difficult to balance low construction cost and construction process complexity. For example, sleeve grouting connection has stable performance, mature technology and wide application, but the process is complex and the technical requirements are high; grout anchor lap connection is simple and low cost, but the lap length of the steel bars is long and the application is strictly limited; bolt connection is easy to operate and controllable to install, which can greatly reduce temporary support and has high construction efficiency, but the construction cost is high.

[0006] (3) Unstable mechanical properties of the connection: Due to the limitations of the connection method, the mechanical properties of the connection often fail to meet the requirements of seismic resistance and shear resistance. Utility Model Content

[0007] This utility model provides a prefabricated shear wall structure with flat joint vertical connection to overcome the defects of existing prefabricated shear wall connection methods, such as incomplete grouting and unstable mechanical properties of the connection parts.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] This utility model discloses a prefabricated shear wall structure with a horizontal joint and vertical connection, including a prefabricated shear wall body. The lower part of the prefabricated shear wall body is integrally provided with an inverted trapezoidal groove. A C60 pad is integrally provided at the bottom of the inverted trapezoidal groove. A ground beam is connected below the C60 pad. A grouting groove is provided inside the shear wall body. The grouting groove includes reinforcing bars and surrounding filling grout, and the filling grout is concrete.

[0010] Furthermore, each of the inverted trapezoidal tooth sockets has an integrally formed cylindrical C60 pad at the bottom of the socket, with flow space left on the left and right sides of the C60 pad.

[0011] Furthermore, the C60 pad has a trapezoidal structure, which can effectively promote smooth concrete flow during grouting, prevent the formation of cavities in the dark, and effectively improve the mechanical properties of the connection.

[0012] Furthermore, the reinforcing bars include horizontal and vertical reinforcing bars of the wall that are lapped together perpendicularly, and the reserved lapped bars of the ground beam are lapped together with the vertical reinforcing bars and stirrups of the wall respectively.

[0013] The beneficial effects achieved by this utility model are as follows: the trapezoidal structure design promotes concrete flow during grouting, ensures dense grouting, avoids hidden cavities, and improves the shear strength of the connection parts; this connection structure reduces the lap length of steel bars during construction, simplifies construction steps, and reduces construction costs and time; the use of ultra-high performance concrete as grouting material enhances the seismic performance of the shear wall, and compared with cast-in-place structures, it has better seismic resistance and durability.

[0021] Example 1

[0022] like Figure 1-4 As shown, a prefabricated shear wall structure with vertically connected flat joints includes a prefabricated shear wall body 1. The prefabricated shear wall body 1 has an integrally formed inverted trapezoidal groove 2 at its lower part. A C60 pad 3 is integrally formed at the bottom of the inverted trapezoidal groove 2. A ground beam 4 is connected below the C60 pad 3. A grouting groove is provided inside the shear wall body 1. The grouting groove includes reinforcing bars 5 and surrounding filling grout, and the filling grout is concrete 6.

[0023] Each of the inverted trapezoidal tooth sockets 2 has an integrally formed cylindrical C60 pad 3 at the bottom of the tooth socket, with flow space left on the left and right sides of the C60 pad 3.

[0024] The C60 pad 3 has a trapezoidal structure, which can effectively promote the smooth flow of concrete 6 during the grouting process, fill it densely, prevent the formation of cavities in the dark, and effectively improve the mechanical properties of the connection part.

[0025] The reinforcing bars 5 include horizontal reinforcing bars 51 and vertical reinforcing bars 52 that are perpendicularly lapped together. The reserved lapped bars 54 of the ground beam are lapped together with the vertical reinforcing bars 52 and the stirrups 53 of the wall, respectively.

[0026] The vertical reinforcing bars 52 of the wall are lapped and connected to the reserved lapped bars 54 of the ground beam. The filling of concrete 6 can greatly reduce the lap length of the reinforcing bars. The superior bonding and anchoring performance of ultra-high performance concrete 6 ensures the strength and stability of the reinforcing bar connection. Moreover, the precast concrete frame structure based on ultra-high performance concrete 6 has better seismic performance than cast-in-place concrete structure.
