DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel frame at a construction site of a steel building by joining and fixing an intermediate beam of a horizontal beam to a short connecting beam protruding in a cantilever form from a standing steel column. The present invention relates to a position adjusting device for a connection beam and an intermediate beam of a steel frame building used for aligning end faces of the connection beam and the intermediate beam to be joined. In the present invention, in order to connect and fix the intermediate beam, which serves as a cross beam between columns, to a side portion of the column, it is attached to a required position of the column and protrudes in a cantilever shape.
A connection member used as a joint end surface of the intermediate beam is called a connection beam.

2. Description of the Related Art At the construction site of a steel frame building, as shown in FIG. 3, an end of a connection beam 2 projecting from a side of a steel column 1 and an end of an intermediate beam 3 serving as a horizontal beam of the steel column 1 are connected. It has a steel structure in which the intermediate beam 3 is connected and fixed between the steel columns 1 by joining and fixing. To connect the intermediate beam 3 between the steel columns 1, the other end of the intermediate beam 3 must be connected to the other end. In a state temporarily fixed to a steel column (not shown) on one side, an end surface 23 of one side of the intermediate beam 3 is joined to an end surface 22 of the connection beam 2 of the steel column 1 on one side of the steel column 1. The steel frame assembly method of connecting and fixing is adopted.

However, it is substantially difficult to align the end face 23 of one side of the intermediate beam 3 connecting the other side to another steel column with the end face 22 of the connection beam 2 with "right". Often, a considerable displacement occurs between the two. However, special tools for correcting the misalignment between the end faces 22 and 23
Since an apparatus has not been developed, a complicated manual operation of positioning the wire by hanging the wire on the intermediate beam 3 and pulling the wire with a hand or a winch is performed.

[0004]

The above-mentioned conventional intermediate beam 3
The work of aligning the connection beam 2 and the connecting beam 2 is an inefficient work that requires a lot of trouble and time, and is extremely dangerous because it is a work at a high place. There is a need in the art for the development of specialized devices that can be used.

The present invention has been made to solve the above-mentioned drawbacks of the prior art and to provide an apparatus for adjusting the position of a connection beam and an intermediate beam which meets the technical requirements in the field.

[0006]

The position adjusting device of the present invention which solves the above technical problem is a position adjusting device of an intermediate beam which is joined and connected to a connection beam projected from a steel column of a steel building.
A hydraulic jack having a hand pump with a hand pump is provided so as to be detachably provided along a side of the connection beam and has an attachment portion to the connection beam, and receives and holds the hydraulic jack with a hand pump in front of the connection beam. The position adjusting member includes a fixing member and a position adjusting member attached to an operating shaft of the hydraulic jack, and the position adjusting member presses against an end face of the intermediate beam to protrude forward a position adjusting wheel for forcibly moving the intermediate beam in the left-right direction. And a structure in which an operation unit for rotation of the position adjustment vehicle is protruded upward.

[0007] Similarly, as an intermediate beam position adjusting device, it has the same fixing member as the first invention, and has a fulcrum that is supported on the side of the connection beam, so that the operating shaft of the hydraulic jack can be adjusted to a point of force. A tension member for connecting an operation point of the operation member to the intermediate beam; pulling the tension member by operating the hydraulic jack to connect the intermediate beam to the connection beam; The second invention of the "structure forcibly approaching".

That is, according to the first aspect of the invention, the position adjusting wheel is pressed against the end face of the intermediate beam by operating the hydraulic jack, and the position of the intermediate beam is moved backward, or the intermediate beam is rotated by rotating the position adjusting wheel. It is forcibly moved in the left and right direction, and the position of the intermediate beam is adjusted by mechanical means, and the position adjustment in the left and right direction by the position adjustment wheel is adjusted until the end of the intermediate beam is removed from the top of the position adjustment wheel, Subsequent fine adjustment is carried out by manual work using a tool such as a hammer to align and join both end faces.

[0009]

According to the position adjusting device of the first invention, when the intermediate beam is joined and connected to the connection beam on the side of the steel column, the end surfaces of the two beams are displaced and the intermediate beam is displaced in the left-right direction of the connection beam. Or
When the intermediate beam is excessively protruding to the connecting beam side, the hydraulic jack is operated, and the position adjusting wheel of the position adjusting member is pressed against the end face of the intermediate beam to retreat the intermediate beam that is excessively protruding, By rotating the position adjustment wheel, the intermediate beam is forcibly moved in the left and right direction, mechanically adjusting the position shift posture, and supplementing only the remaining fine adjustment by hand,
Both end surfaces can be joined.

Further, the position adjusting device according to the second aspect of the present invention includes:
When the end face of the intermediate beam is too far from the end face of the connecting beam, the intermediate beam is pulled out toward the connecting beam by operating the operating member by operating the hydraulic jack, and both end faces are mechanically aligned. Can be.
