Description

Technical Field

[0001] The utility model belongs to the technical field of building construction tools, and in particular relates to a tool-type scaffolding wall connecting piece. Background Art

[0002] Wall ties generally refer to components that strengthen the stability of other structures by connecting to reliable fixed ends. In construction projects, they are used to connect the scaffolding frame to the main structure of the building. They are components that can transmit tension and pressure. The wall connection achieved by wall ties plays a very important role in strengthening the overall stability of the scaffolding, improving its stable bearing capacity and avoiding major accidents such as tipping or collapse.

[0003] The existing wall connecting parts and scaffolding are usually connected by fasteners. When the fasteners are used to fix the horizontal bars and vertical bars of the scaffolding, usually one screw is required for each horizontal bar and vertical bar, which makes the fixing operation more complicated.

[0004] A tool-type external scaffolding wall connecting member disclosed in Chinese patent CN210086792U adopts a side beam side elevation connection mode to avoid the masonry construction site and avoid the common quality problem of wall leakage caused by the quality problem of the hole filling operation. However, while solving the problem, the tool-type external scaffolding wall connecting member has the following defects:

[0005] The device uses a U-shaped steel ring and two extended nuts embedded in the side beams of the building to prevent the wall connection from pulling. Since the U-shaped steel ring and the extended nuts are welded and the nut holes of the extended nuts are exposed outward, the embedded depth of the embedded structure cannot be adjusted, and better tensile resistance cannot be obtained by deepening the embedded depth. At the same time, the U-shaped steel ring and the extended nuts cooperate in a way that there is no structure to limit the tensile resistance after being pulled. The overall stress point is on the U-shaped steel ring with a smaller stress surface, which makes the overall tensile resistance of the device poor. Utility Model Content

[0006] The technical problem to be solved by the utility model is that it is impossible to obtain better tensile strength by deepening the pre-embedded depth. Aiming at the deficiencies of the prior art, a tool-type scaffolding wall connecting piece is provided.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] It includes a fixing clamp for fixing the scaffolding rod body and an embedded part embedded in the concrete beam body, and also includes a connecting part for respectively connecting the fixing clamp and the embedded part; the fixing clamp is provided with an accommodating cavity for accommodating and fixing the scaffolding rod body and a fixing block for fixing the scaffolding rod body, and the fixing clamp fixes the scaffolding crossbar and vertical bar by a single bolt; the embedded part includes a cylinder body connected to the connecting part and a connecting plate, a closed pad is provided between the cylinder body and the concrete beam casting template, an anti-slip bolt is sleeved inside the closed pad, and the anti-slip bolt is threadedly connected to the cylinder body.

[0009] Furthermore, the fixing clamp includes two groups of mutually hinged fixing parts, wherein one side of the fixing parts of one group is provided with a vertical accommodating cavity and a horizontal fixing block, and one side of the fixing parts of the other group is provided with a horizontal accommodating cavity and a vertical fixing block, the horizontal fixing block is used to fix the horizontal bar part of the scaffolding rod body in the horizontal accommodating cavity, and the vertical fixing block is used to fix the vertical bar part of the scaffolding rod body in the vertical accommodating cavity.

[0010] Furthermore, the transverse fixing blocks are arranged on the left and right sides of the vertical accommodating cavity; and the vertical fixing blocks are arranged on the upper and lower sides of the transverse accommodating cavity.
