Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering and steel structure construction, and relates to an adaptive fine installation method for a multi-angle swing column of a pin shaft base, and in particular to an installation method for a multi-angle swing column of a pin shaft base which is easy to operate, has high working efficiency, high installation precision and low cost. Background Art

[0002] Pin-base steel columns are usually used in designs that require stress release as the temperature changes during the use of the building. The characteristic is that the steel column can rotate around the pin at the bottom of the column in a direction perpendicular to the pin. Since the steel column is long and the top is connected to other structures, the inclination deviation is reflected through the displacement of the top of the column and is magnified several times, affecting the construction of adjacent structures. At present, there are two methods for adjusting the installation angle of the swing column. One is to set multiple lifting ears, and adjust the angle of the steel column by means of steel wire ropes and fall chains, and tie it to the surrounding structure. This method has a cumbersome operation process, slow installation speed, and low installation accuracy. The other is to use an angle adjustment device. The problem is that the device structure is complex and not very practical.

[0003] Therefore, it is of great practical significance to develop a method for installing a multi-angle swing column on a pin base that is easy to operate, has high working efficiency, high installation accuracy and low cost. Summary of the invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a method for installing a multi-angle swing column of a pin base which is easy to operate, has high operating efficiency, high installation precision and low cost, thereby solving the defects of the current installation angle adjustment of the pin base swing column, such as cumbersome operation, low operating efficiency, low installation precision and excessively high cost.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A method for self-adapting and finishing a pin-shaft base multi-angle swing column, comprising the following steps:

[0007] (1) Processing the support and arranging the support next to the position where the multi-angle swing column of the pin base is to be installed, wherein the support is in a Λ shape as a whole and a baffle is fixed on the top of the support;

[0008] (2) The jack is arranged on the baffle plate with the operating direction of the jack perpendicular to the baffle plate, and the adaptive adjustment device is placed on the driving end of the jack, wherein the adaptive adjustment device comprises two clamping plates which are parallel to each other and arranged at a distance, one side of the two clamping plates is provided with a bottom plate which is fixedly connected to the two clamping plates at the same time, and the other side is connected to the adaptive adjustment plate installed between the two clamping plates through a revolute pair;

[0009] (3) Lift the multi-angle swing column to be installed, and fix the multi-angle swing column to be installed with the pin shaft base through the pin shaft in a vertical state;

[0010] (4) adjusting the position of the hook so that the multi-angle swing column to be installed tilts toward the support until the adaptive adjustment plate is in close contact with the column wall of the multi-angle swing column to be installed;

[0011] (5) The installation angle of the multi-angle swing column to be installed is fine-tuned by controlling the jack, thereby completing the adaptive assembly of the multi-angle swing column of the pin shaft base.

[0012] The supports used can be quickly processed using the remaining materials on site. They have low processing accuracy. The errors caused by the embedded parts position, support position and angle can be adjusted through the adaptive adjustment device. It is highly practical and can complete the adjustment of the multi-angle swing column to be installed at one time using a jack. The installation speed is fast and the accuracy is high.
