BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction guide device for a steel column used when a square column made of a steel frame is added upward to form a single steel column.

[0002]

2. Description of the Related Art In a steel column having a rectangular column made of a steel frame whose upper end is closed and whose lower end is opened and which is joined to each other up and down, the following column is connected to the upper end of the column previously installed and fixed. The columns are lifted and arranged and temporarily fixed with erection pins provided on the four sides of the connection portion, and then the upper and lower ends of the columns are welded to be joined to an integral steel column.

[0003]

[Problem to be Solved by the Invention] The problem in such a case is that the next pillar to be connected is in an unstable state while being lifted, so that it is likely to be misaligned, and a plurality of persons are required to perform the alignment. It requires workers.

In order to solve the above-mentioned conventional problems, an inner guide is erected on the closed end face of the pillar to obtain a certain effect. However, the opening edge of the upper pillar built with the inner guide is obtained. However, it is still insufficient to prevent displacement even due to slight clearance, and further improvement is desired.

Therefore, the purpose of the present invention is not to hinder the installation of the pillar by hanging it down, but to align the orientation of the pillar and only to install the pillar. An object of the present invention is to provide a new steel column construction guide that can be guided to a fixed position at the upper end of a lower column.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a rectangular column made of steel having a corner member in a central portion in which an outer corner is accommodated, and joint plates provided at both ends to surround the upper end of the column. It consists of a pair of bent frame members forming an attachable quadrilateral frame, and a guide plate having an inner side inclined upward, and a pair of the guide plates is provided on both sides of the inner corner of the corner member of each bent frame. Opposite to the shape, it consists of an outer guide protruding at the opposing corner of the column, and an inner guide with a plate body crossed upright on all sides leaving a built-in space on the closed end face of the upper end of the column at the periphery That is.

[0008]

[Operation] In the above configuration, when the next upper pillar is hung over the lower pillar that was previously installed and fixed, the opening at the lower end is fitted into the inner guide, and the inner guide pushes back. The horizontal displacement at the time of hanging down is temporarily corrected.

Further, the upper column is slightly rotated by the clearance between the inner guide and the lower end opening of the upper column, the opening edge is displaced obliquely with respect to the upper edge of the lower column, and the opposing corner is shifted from the upper edge. When projecting, the projecting portion contacts the inclined side inside the outer guide, and the upper column naturally rotates and changes direction due to its own weight and the inclined side while the open end contacts the upper edge. The misalignment is secondarily corrected so that the corners of the upper and lower columns coincide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numerals 1 and 1 denote quadrangular frames 2 of an outer guide device.
As shown in FIG. 2, a pair of right-angled bent frame members having a corner member 3 in the center where the outer corner of a square pillar 11 made of steel fits in the center portion, Joint plates 4, 4 are provided vertically. In the illustrated bent frame materials 1 and 1, the central portion and both end portions are box-shaped bodies formed by welding steel plates, and the box-shaped bodies are formed by the steel pipes 6 and 6 as the corner members 3 and the end members 5 and 5. The joints are integrally connected to each other to reduce the weight, and the joint plates are jointed with each other by bolts 7 to thereby form the column 11.
To form the quadrilateral frame 2 that can be attached to the periphery of the upper end of the frame.

Numeral 8 is a vertically long (height: 200 mm, width: 70 mm) trapezoidal guide plate in which the inner side 9 is inclined upward at an angle of about 15 °. 1
Are provided on both sides of the inner corner 10 of each of the corner members 3 and 3 so as to face each other, thereby forming an outer guide projecting from the opposite corner of the column 11.

All of the pillars 11 have an upper end closed by a top plate 12, and a connecting ring 13 is integrally provided in an opening at a lower end with a lower edge protruding therefrom.

At the center of the closed end face of the column 11, inner guides 14, 14 made of a steel plate having a required thickness are provided so as to intersect in four directions while leaving a space for installation on the periphery. This guide 1
The upper portions of the side end surfaces of the side surfaces 4 and 14 are formed as inclined surfaces, and support pieces 15 and 15 whose side surfaces are formed as inclined surfaces except for the base end portion are joined at right angles to both lower sides of the vertical side end surfaces.

On the four walls at the lower end of the column 11, bolts 16 and 16a for temporary support are screwed horizontally in two steps vertically at positions corresponding to the inner guide side end surfaces of the lower walls. The screw holes located are penetrated.

The upper column 11 with respect to the lower column 11A
The construction of B is the same as before.
1B is suspended. Prior to the suspension, the pair of bent frame members 1 and 1 are protruded from the beam
The joint plates 7, 7 which abut against the upper two ends of the frame and which abut against each other, are bolted to form a quadrilateral frame 2
And attached around the column. As a result, the pair of guide plates 8, 8 protrude from the opposite corners of the column 11 as outer guides.

After such preparation is completed, the lower end openings are placed on the inner guide with the pillars aligned with each other, and are suspended as they are.
At the same time, the positional deviation in the horizontal direction is temporarily corrected by being pushed back by the inner guide.

During the installation, the upper column 11B is rotationally displaced by a slight clearance (not shown) between the inner guides 14, 14 and the lower end opening of the upper column 11B. As shown, when the opening edge is obliquely displaced with respect to the upper edge 11a of the lower column 11A and the corner 11b projects from the upper edge 11a, the protruding portion is used as an outer guide to oppose the lower column 11A. The guide plate 8, 8 protruding outside the corner is guided in contact with one of the inclined sides 9 of the guide plate 8, 8.

As a result, the opening edge of the upper pillar 11B is naturally pushed back by its own weight by hanging and the guide of the inclined side 9 which is located obliquely in the direction of the corner with respect to the upper edge 11a. As a result, the upper column 11B rotates and the positional deviation is secondarily corrected, so that the corners of the upper and lower columns coincide.

The lower pillar 11A positioned by the inner and outer guides is temporarily supported by the bolts 16 and 16a until the pillars are integrated by welding. For temporary support, bolts 16 and 16a are screwed in order from the bottom into bolt holes drilled in the lower end wall after building,
This can be easily performed by contacting the tip of the bolt with the side end surface of the inner guide 14. In some cases bolt 16
, A very slight displacement in the horizontal direction can be adjusted, and the inclination can be adjusted by the bolt 16a.

[0020]

In the present invention constructed as described above, a quadrangular frame formed by a pair of bent frame members is used.
The guide plates opposing in the shape of a gate on both sides of the inner corner of the corner member at the center of the bent frame can be installed as outer guides projecting from the opposite corners of the pillar, so that installation is not troublesome and easy to remove Since it can be performed, it can be used for building the upper pillar immediately after the joining is completed.

Also, the upward inclination of the inner side of the guide plate naturally corrects the misalignment caused by the rotational displacement, which has been troublesome until now, and the angles of the columns coincide with each other without any effort. The work efficiency is remarkably improved and the construction period is shortened.

Further, the inner guides which are erected in four directions while leaving a space on the closed end of the upper end of the column at the periphery are temporarily corrected for the displacement, and then the column guides are formed by the outer guide. Since the corner alignment is performed secondarily, the pillar can be more reliably erected, and the positional accuracy can be improved.
