Description

Technical Field

[0001] This invention relates to the technical field of auxiliary devices for laser drilling of circuit boards, specifically to an assembled steel pipe recycled concrete column and its application method. Background Technology

[0002] With the rapid development of my country's economy, a variety of equipment is used in construction. Among these auxiliary equipment, steel pipe recycled concrete columns are the most frequently used. The design of steel pipe recycled concrete columns can make the construction of buildings more efficient.

[0003] Chinese Patent Publication No. CN218438555U, authorized on February 3, 2023, discloses a novel steel pipe recycled concrete column with FRP reinforcement. The column comprises FRP profiles, FRP reinforcements, recycled concrete, a steel pipe, and FRP strips. The FRP profiles are positioned at the center of the steel pipe. Recycled concrete is poured inside the steel pipe. Several FRP reinforcements are adhered to the inner wall of the steel pipe. FRP strips are circumferentially wrapped around the outer wall of the steel pipe. Both the FRP reinforcements and the steel pipe have circular cross-sections and a height of 500mm. The FRP reinforcements have a diameter of 3mm. The steel pipe has an inner diameter of 200mm and a wall thickness of 5mm. The FRP profile is I-shaped, with a length L of 500mm, a cross-sectional height h of 140mm, a cross-sectional width b of 80mm, a flange thickness t of 9.1mm, and a web thickness d of 5.5mm. Eight FRP reinforcements are uniformly adhered to the inner wall of the steel pipe.

[0004] Although the above-mentioned solution can effectively delay the local buckling of the steel pipe by setting equally spaced annular FRP strips under circumferential constraint, and saves more FRP material compared with the FRP strips fully wrapping the outer wall of the steel pipe, it often has the problem of increased swaying probability during use due to insufficient stability during assembly. In response, we propose an assembled steel pipe recycled concrete column and its application method. Summary of the Invention

[0015] A method for using an assembled steel-tube recycled concrete column includes the following steps:

[0016] Step 1: First, remove the main body of the steel pipe recycled concrete column.

When the threaded ring block limiting groove 10 and the threaded ring block 11 are sealed together, the leak-proof upper ring block 22 set at one end of the inner limiting ring block 4 will be fixed on one side of the leak-proof lower ring block 17, thereby increasing the tightness of the connection.

[0040] Step 2: After the assembly of this type of assembled steel pipe recycled concrete column is completed, the multiple compressive inner ring blocks 5 set inside the main body 1 of the steel pipe recycled concrete column can effectively increase the compressive strength of the main body 1 of the steel pipe recycled concrete column during use.
