Technical Field

The invention relates to the technical field of building structure engineering.

Background

The prestressed stay bar steel column formed by the stay bars and the pretension cables can effectively improve the stability of the pressed steel column. At present, a stay bar and a central column in a prestressed stay bar steel column are mostly connected in a field direct welding mode, and the stay bar and the central column also mostly adopt the same section shape. The construction quality is difficult to ensure by adopting a field welding mode, and the welding residual stress also has adverse effect on the stability of the steel plate. Furthermore, it is desirable in some cases to design the struts and the central column in different cross-sectional forms. For this reason, it is of great engineering background and interest to develop a form of fabricated connection that allows for the transition from a center post to a strut cross-section.

Disclosure of Invention

The invention aims to provide a sleeve type connection mode which can realize the conversion of the section of a prestressed stay bar steel column stay bar and is simple to operate and convenient to install.

The technical scheme adopted for achieving the purpose of the invention is that a sleeve type connection mode capable of achieving the section conversion of a prestressed stay bar steel column stay bar comprises a rectangular section steel column (1), a rectangular sleeve (2), a steel pipe I (3), a circular sleeve (4) and a stay bar II (5).

The rectangular section steel column (1) is connected with the rectangular sleeve (2) through a plurality of self-locking one-way bolts.

One side of the rectangular sleeve (2) departing from the rectangular section steel column (1) is perpendicularly welded with a steel pipe I (3), and the free end of the steel pipe I (3) is connected with a support rod II (5) through a circular sleeve (4).

Furthermore, the end that steel pipe I (3) and vaulting pole II (5) are connected is provided with the external screw thread, and the external screw thread of steel pipe I (3) and vaulting pole II (5) all matches with the internal thread of circular sleeve (4).

1. according to the invention, the stay bar is connected with the central rectangular section steel column through the rectangular sleeve, the steel pipe and the circular sleeve, so that the construction difficulty is reduced and the construction efficiency is improved due to the assembly type installation.

2. According to the invention, the rectangular section steel column is connected with the rectangular sleeve through the plurality of self-locking type one-way bolts, so that the connection between the closed section component and the rectangular sleeve is not dependent on field welding, and the adverse effect of welding on steel is reduced.

3. According to the invention, the steel pipe is connected with the support rod through the circular sleeve, so that the prestress of the stay cable is changed by adjusting the length of the stay cable, and the construction precision is improved.

4. The invention realizes the assembled connection of the section conversion from the central column to the stay bar, thereby being applicable to different design forms.
