9. A method for installing a beam column of an assembled building steel structure, which uses the assembled building steel structure beam column installation equipment as set forth in any one of claims 1 to 8, and is characterized by comprising the following steps:
S1, respectively arranging two groups of climbing assemblies on the surfaces of two upright posts (1), placing a cross beam (22) in adjustable positioning assemblies of two concave plates (17), screwing a screw (21) to adjust the distance between a first positioning block (18) and a second positioning block (20), enabling the surface of the second positioning block (20) to be in contact with the surface of the cross beam (22), and enabling the adjustable positioning assembly to limit the position of the cross beam (22);
s2, starting a second hydraulic cylinder (11) to drive a second clamping block (9) to clamp the upright post (1), and controlling a third hydraulic cylinder (12) to lift the telescopic rod (8) to drive the first driving assembly and the lifting assembly to move upwards;
S3, after the first clamping module reaches a preset height, starting the first hydraulic cylinder (4) to drive the first clamping block (2) to clamp the upright post (1), releasing the clamping of the second clamping block (9) and contracting the third hydraulic cylinder (12) to lift the second clamping module;
s4, repeating the steps S2-S3 to climb circularly until the cross beam (22) reaches the installation position, and then performing welding fixation.
10. The method for installing the beam column of the fabricated building steel structure according to claim 9, wherein the method comprises the following steps:
A. When an oblique cross beam (22) needs to be installed between two upright posts (1), firstly, the initial stroke adopts a synchronous lifting mode to ensure a positioning reference;
B. The middle travel is switched to a differential lifting mode to generate an inclination angle, and the design inclination angle theta of oblique installation of the cross beam (22) is input to calculate the target height difference, the third hydraulic cylinder (12) at the high position side is accelerated to 1.2 times of basic speed, the third hydraulic cylinder (12) at the low position side is decelerated to 0.8 times of basic speed, and the height difference is formed by multiple lifting at the high position side and less lifting at the low position side in unit time in a cumulative way;
C. And returning to the synchronous lifting mode when the actual height difference enters a range of +/-2 mm, and entering a final state synchronous fine adjustment process until the inclination angle error is less than or equal to 0.3 degrees.
