Description

Coupler type Device for Joint of H-Shape Steel

The present invention relates to a device for connecting H-beams in series, and more particularly, to a coupler-type joint that can connect H-beams in series without directly welding or bolting H-beams in series.

There is a horizontal brace method as a soil barrier support method. Horizontal brace construction method, as shown in Figure 1, to prevent the soil from collapsing by installing a retaining wall and turn the belt along the retaining wall is a way to receive the earth pressure by installing a vertical prop and horizontal brace. In such horizontal brace construction method, the belt and the brace are often constructed with H-beam temporary materials, but the temporary materials need to be easy to install and dismantle.

On the other hand, since H-beams are manufactured to a certain length, H-beams are installed in series in order to use H-beams as bands or braces in the horizontal brace method. Usually, the series connection of H-beam braces is usually bolted to the flange and web by attaching a joint plate. However, this method is cumbersome in that bolting is performed while fitting the joint plate to the H-beam according to the considerable bolt usage. In addition, since a considerable number of bolt holes must be drilled in the H-beam, there is a problem of cross-sectional loss of the H-beam and disadvantages of recycling of the H-beam.

In order to improve the above problem, a method as shown in FIG. 2 has been proposed. Figure 2 (a) is a method according to Patent No. 10-0699040, as shown in the flange position of the H-shaped steel according to the conventional joining method by the joint plate while welded to the end of the H-shaped steel in the web position of the H-shaped steel The reinforcing plate is additionally added and bolted together while the end plates are joined together. This method has the advantage of reducing the bolting point compared to the conventional method, but also has the disadvantage of having to weld the end plate to the end of the H-beam, and still has the disadvantage of having to drill a bolt hole in the H-beam.

2 (b) is in accordance with patent 10-077212. In the web position of H-beams, the bolts are joined in a state where the end plates welded to the end of the H-beams are joined together, while in the flange position of the H-beams, a bracket is formed to cover the joint ends of the H-beams. This method can be said to be advantageous in that there is no problem due to bolt hole drilling because the direct bolted joint can be avoided to the H-beam compared to the method of FIG. 2 (a). However, there is still a problem due to welding because end plates or reinforcing ribs must be welded to the H-shaped steel ends.

The present invention has been developed to improve the conventional series connection bonding problem of H-shaped steel, and to provide a coupler type joint that can be connected in series between the H-shaped steel without directly welding or bolting to H-shaped steel. There is.

In order to solve the above technical problem, the present invention is a coupler-type coupler that can be connected in series with the original H-shaped steel without separate processing without directly welding or bolted to the H-beam, coupler unit It consists of a set of four to provide a coupler-type joint of the structure that the coupler unit is bolted to each other.

Here, the coupler unit, a U-shaped flange channel; A web plate that is bent at one end of the flange channel to be perpendicular to the flange channel so as to be interviewed by the web of the H-beam; A flange binding plate that extends vertically at the other end of the flange channel and has a bolt hole in the plane; A flange plate extending horizontally from an end of the web plate and having a bolt hole formed therein; A web plate extending vertically at one end of the flange plate to face the web of the H-beam; A flange binding plate that extends vertically from the other end of the flange plate and has a bolt hole in the plane; A web binding plate which is bent horizontally at the end of the web plate and has a bolt hole formed in the plane; Characterized in that it consists of; bearing plate bonded to the center of the inner peripheral surface of the L-shaped cross section by the flange plate and the web plate.

According to the present invention, the following effects can be expected.

First, the coupler-type joint according to the present invention can be easily manufactured in the factory because it is composed of a coupler unit of the same type. In addition, the factory-made coupler type joints have excellent field applicability because the coupler units need to be bolted together.

Secondly, by using the coupler-type joint according to the present invention, it is possible to connect the H-beams in series without using any special processing on the H-beams as they are. In other words, the H-beams can be connected in series to each other without drilling holes in the H-beams or welding the various backing plates. In this way, since H-steel is not specially processed, it can be advantageously reused after using H-beam as a temporary material. This can lead to construction cost reduction due to material cost reduction in various temporary construction work using H-beam such as horizontal brace construction method.

Third, the coupler-type joint according to the present invention, when installed in the series connection joint of the H-shaped steel, because the H-shaped steel is crimped and restrained during the bolting process between the coupler unit, it is possible to connect the H-shaped steel in series while ensuring the stability of the joint. Furthermore, since the cross-sectional thickness increases by the coupler type joint in series connection joints of H-beams, the strength at the joint is expected to increase.
