Description

Technical Field

[0001] The utility model relates to the technical field of masonry wall construction, in particular to an adjustable tie bar structure. Background Art

[0002] At present, according to seismic requirements, the internal infill masonry walls of frame structures, frame-shear structures, shear wall structures, etc., require two tie bars to be embedded in the masonry wall every 500mm or so between the main vertical structure and the masonry wall. The length of the tie bars varies from 700mm to the entire length of the masonry wall, depending on the seismic resistance level. Since the frame columns or shear walls are surrounded by formwork during casting, it is difficult to pre-embed the tie bars. Post-embedding is generally chosen on-site to embed the tie bars into the frame columns or shear walls. During construction, the tie bar embedding locations are first marked on the shear wall or frame column, and then holes are drilled to embed the bars. During actual construction, due to the large number of tie bars, the tie bars need to be embedded one by one into the completed structure, which is time-consuming and labor-intensive. It is also possible that the two steel bars will not be on the same horizontal plane, and the positioning spacing is difficult to control. Overall, the role of the tie bars is reduced, resulting in poor results.

[0003] Therefore, in order to solve the above problems, there is an urgent need for an adjustable tie bar structure that can limit and trim the position of the tie bars, effectively solve the problems of two tie bars not being on the same horizontal plane and the positioning spacing being difficult to control, and at the same time can realize factory customization and improve construction efficiency and quality.

At the same time, it can be customized in the factory to improve construction efficiency and quality.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An adjustable tie bar structure includes a structural column, an adjustable tie bar connection assembly, and a block wall.

The inner side of the sleeve joint is provided with a through internal thread, and the outer circumference of the connector is provided with an external thread that is compatible with the internal thread. One end is vertically welded to the tie bar, and the other end is threadedly connected to the sleeve joint. The tie bar and the connector are symmetrically arranged in two groups, which are threadedly connected by the sleeve joint through the connector. The structural column is fixedly connected to the block wall through the adjustable tie bar connection assembly.

[0007] Furthermore, the adjustable tie bar connection assembly is perpendicular to the structural column and parallel to the block wall.

[0008] Furthermore, the length of the anchor connection between one end of the tie bar and the structural column is 10-15 cm.

[0009] Furthermore, the distance between the two tie bars is 12cm-16cm.
