Description

Technical Field [0001] The present invention relates to a method of constructing a steel beam,

More particularly, the present invention relates to a method of installing a double bracket made of a pair of steel beams having a length greater than the steel column width on the outer surface of a steel column, The present invention relates to a joining method for joining a steel beam to a steel beam.

Generally, in the case of a steel frame structure, a steel column such as an H-shaped steel or a rectangular steel pipe is often used. In the case where the steel column is a rectangular steel pipe, the structure of the steel beam is different depending on the shape of the steel column. This is an additional requirement.

The diaphragm of the square steel pipe column is difficult to be manufactured and installed, and there is a problem that welding defect occurs, resulting in brittle fracture, and there is a disadvantage in that the force transmission is unclear, There is a problem in that it is difficult to manufacture and install because of the complicated details of the joining part connected to the steel beam compared to the steel column so that it is limited to general use.

Also, the structure of steel beam beams is different from each other depending on the shape of the steel column, and there are many problems to be considered in selecting the steel column member shape.

Therefore, it is required to have a steel beam connection structure which can be applied in the same form irrespective of the steel columnar shape, and has improved manufacturing performance and construction performance.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a steel beam joining method capable of simplifying a joining structure between a steel column and a steel beam member, It has its purpose.

In order to achieve the above object, the present invention provides a joining structure of a steel column and a steel beam, such as an H-shaped steel or a rectangular steel pipe, comprising a pair of steel plates having a length longer than the steel column width on the outer surface of the steel column. Placing the double brackets in a parallel arrangement and welding them, and welding them; Joining the double brackets provided at the ends of the steel brackets with the double brackets and the double girder members parallel to each other in the vertical direction to form a double girder member inner space with a double bracket length; Joining the beam member to the double girder member with a pin joint; Installing a deck plate or a deck plate in the space inside the girder member; And filling a concrete in a double girder inner space provided with the form or deck plate to construct a steel beam composite joining method.

The present invention has the following effects: the double bracket 2, the double girder member 3 provided at the end of the double bracket 2, and the beam member 4 connected to the double girder member 3.

First, the steel beam can be joined with a simple structure with the double bracket (2) irrespective of the shape of the steel column (1).

Second, the concrete 6 can be filled in the internal space 5 of the double girder member 3, so that it can be constructed with a steel frame composite beam excellent in structural rigidity.

Thirdly, the beam member 4 joined to the double girder member 3 can have structural efficiency and safety such as reduced sag due to reduced sag.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the scope of the present invention but is only illustrative and various modifications are possible within the scope of the present invention.

2 to 4 are perspective views of the steel column 1 with a double bracket 2 provided thereon. The double bracket 2 is composed of a pair of steel plates having a length greater than the width of the steel column 1, ) Are arranged in parallel and welded to each other.

As shown in the drawing, the present invention has the feature that the same construction can be made irrespective of the shape of the steel column 1, and the length and size of the double bracket 2 made of the c-shaped steel, .

For H-column steel columns (1), double brackets should be installed on flange of H-column steel column (1), and BOX columns such as square column steel columns (1) or square CFT columns should be parallel To install the double bracket.

5 is a perspective view of the double bracket 2 in the state where the double girder member 3 is provided at both ends of the double bracket 2 provided on the steel column 1 and the side of the double girder member 3 is connected to the end of the double bracket 2 And bolted to the pin joint.

At this time, since the double girder member is connected to the double bracket at four points, the structural stability against the joint can be improved.

The double girder member 3 is formed on both sides of the double bracket 2 and is formed in a shape in which the double girder member 3 is parallel to the double bracket 2 in the vertical direction, 3) an inner space 5 is formed.

It is possible to install a formwork or a deck plate in the internal space 5 formed by the double girder member 3 and then fill the concrete 6 with the steel composite beam as shown in FIG.

As shown in FIG. 8, only the end of the girder member can be constructed by a steel frame composite beam, or the entire girder member can be used as shown in FIG. 9, And the portion not to be constructed by the steel frame composite beam can be constructed only with the double girder member 3 as shown in FIG.

Fig. 6 is a perspective view of the double girder member 3 with the beam member 4 mounted thereon. The double girder member 3 and the beam member 4 are connected to each other by bolts.

The beam member 4 is generally designed on the basis of the span to determine the size of the member. The span of the beam member 4 is reduced by the length of the double bracket 2, thereby achieving structural efficiency and safety.

FIG. 7 is a perspective view of a frame structure according to an embodiment of the present invention. As shown in FIG. 7, a concrete structure is installed on a steel structure frame and a slab 7 is installed.
