Description

[Detailed explanation of the idea] In a steel frame structure, the erection of the steel columns is corrected before installing the steel beams.

The present invention relates to such a steel column erection correction device, in which the right-hand threaded portion 3a of the outer peripheral surface of the inner cylinder 3 is screwed into the threaded portion of the inner peripheral surface of the outer cylinder 1, and the tip of the outer cylinder 1 is The wedge piece 4 with the block 4a disposed at the lower end is slidably inserted into the wedge piece 4, and the left-hand threaded portion of the outer peripheral surface of the screw rod 4b hanging down from the block 4a is inserted into the screw hole 3c at the tip of the inner cylinder 3. At the same time, the screw tube 5 is screwed onto the right-hand threaded portion 1a of the outer circumferential surface of the outer tube 1.
The base ends of left and right links 6 are pivotally attached to the left and right sides of the threaded tube 5, respectively, and a U-shaped metal fitting 7 for holding a flange of a steel column is pivotally attached to the tip of each link 6. This is characterized in that a tightening bolt 8 is threaded onto a metal fitting 7.

In the figure, 2 is a handle attached to the outer periphery of the base end of the outer cylinder 1, and 3b is a prismatic part at the base end of the inner cylinder 3. Grasp the same part 3b with a tool and screw it. It is designed to move forward and backward into the outer cylinder 1.

Since the present invention is constructed as described above,
Before erecting the lower steel column A and attaching the beam steel, four U-shaped metal fittings 7 at the tips of the left and right links 6, 6 are attached to the flange portions of the steel column A on the front and back sides of the same parts. By clamping the outer cylinder 1 together with the splice plate B, tightening it with the tightening bolt 8, and rotating the outer cylinder 1, The outer cylinder 1 is advanced and pressed onto the splice plate B, thereby fixing the device of the present invention.

Next, by rotating the inner cylinder 3 having the right-hand threaded portion 3a on the outer peripheral surface screwed into the threaded portion on the inner peripheral surface of the outer cylinder 1, the inner cylinder 3 is advanced relative to the outer cylinder 1.
A screw rod 4b having a left-hand threaded portion on the outer peripheral surface in the opposite direction to the right-hand threaded portion 1a on the outer peripheral surface of the inner cylinder 3 is screwed into the tip screw hole 3c of the inner cylinder 3, so that the inner cylinder 3 can move forward. At the same time, the screw rod 4b moves forward with respect to the inner cylinder 3, and the wedge piece 4 connected to the screw rod 4b via the block 4b connects the upper and lower steel frames A, A as shown in FIG.
Since the steel column is wedged into the joint clearance, the erection of the steel column is corrected by adjusting the clearance using the wedge piece 4, and a liner plate or the like is interposed in the clearance. However, at this time, the splice plate B at the joint part of the steel column is divided into two parts so that there is no problem in inserting the wedge piece 4 into the joint part.

When the erection correction of the steel column A is completed in this way, the device of the present invention is removed by the reverse operation to the previous one and is made available for reuse.

In this way, the proposed device allows the erection of steel columns to be easily corrected, and there is no need to straighten wires to straighten them as in the past, improving work efficiency and preventing danger. , and the wedge piece 4
The desired purpose can be achieved by simply dividing the splice plate B into two parts so that the splice plate B can be wedged into the joint clearance of the steel column A, and there is no need to process the main body of the steel column A.

Further, according to the device of the present invention, construction correction work is performed very close to the required steel column, so the number of workers can be reduced and the working time can be shortened. Furthermore, conventional straightening wires may obstruct other operations, but when the device of the present invention is used, other operations will not be affected.

The link 6 may be replaced depending on the size of the flange, and the U-shaped metal fitting 7 may be replaced depending on the shape of the steel column.
The present invention has many advantages, such as being able to be applied to various types of steel columns by replacing the parts, and having a simple configuration and being portable.
