Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connecting device, and more particularly, to a beam connecting and fixing device for connecting and fixing a beam of an H-shaped beam or the like.

Looking at the steel structure of a building or an apartment, you can see a beam connecting horizontally to a column. The beam is usually made of H-shaped steel, square pipe, round pipe.

Patent Publication No. 2011-0138309 proposes a method of connecting a column and a beam. In this method, a beam connector is welded to a circular steel pipe having the same thickness and outer diameter as the column section. As described above, conventionally, when a beam is connected to a column or two beams are connected, a method of piercing or welding a beam is used. When the beam interval is wide, a screw jack is also used.

However, when the beam is permanently bonded, welding is useful. However, if the welding is performed until the temporary bonding, the work must be separately performed at the time of separating later, so that the working efficiency is lowered and the cost is increased. In addition, if the hole is pierced or welded, the beam may be deformed.

Therefore, if only the robustness of the bond is ensured, it is preferable to use a more simple bonding method than welding.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems,

First, it is easy to combine and separate the beams,

Second, the bonding force can be increased when the beams are combined,

Third, it is intended to provide a beam connecting and fixing apparatus which is easy to manufacture and has a low manufacturing cost.

In order to accomplish the above object, a beam connecting and securing apparatus of the present invention may include a body, a first and a second coupling unit, and a beam fixing unit.

The trunk part is located at the center of the beam connecting and fixing device and can support the first and second coupling parts to be coupled to both ends.

The first coupling portion may extend in one direction from the body portion, and may be open to the outside in one direction to form a first receiving portion for receiving and coupling the first beam. At least two coupling holes horizontally spaced at the same height may be symmetrically provided on both sides of the first accommodating portion.

The second coupling portion may extend from the body portion to the other side and may open to the outside in the other direction to form a second receiving portion for receiving and coupling the second beam. At least two coupling holes horizontally spaced from each other at the same height may be symmetrically provided on both sides of the second accommodating portion.
The beam fixing part may include a vertical part having a through hole corresponding to the coupling hole and a horizontal part bent perpendicularly to the vertical part and not having a through hole. The vertical portion may be coupled to the side of the first and second receiving portions, and the horizontal portion may be coupled to the first and second beams to fix the first and second beams in the first and second receiving portions.

In the beam connecting and securing device of the present invention, the first and second receiving portions may be formed in a 'C' shape opening outwardly.

In the beam connecting fixture of the present invention, the first and second receiving portions may be different in size.

delete

The beam connecting fixture of the present invention may further include a gap adjusting member, which can be inserted into the first and second receiving portions to move the first and second beams outwardly.

In the beam connecting and fixing apparatus of the present invention, the trunk portion can be formed of an H-shaped steel.

According to the beam connecting and fixing apparatus of the present invention having such a configuration, for example, when vertically connecting and fixing the H-shaped beams in the horizontal direction, it is possible to combine and separate the upper and lower H- Connection / fixing work is easy.

According to the beam connecting and fixing apparatus of the present invention, since the plurality of through holes are provided, it is possible to flexibly cope with the gap between the upper and lower H-shaped beams, and furthermore, by interposing a wooden pipe or a steel pipe between the beam- It is possible to compensate for the difference in the gap, thereby expanding the application range of the field.

Also, since the beam connecting and securing apparatus according to the present invention is manufactured by cutting a part of the H shape and combining the 'E' shaped coupling parts opened to the outside at both ends thereof by welding or the like, Cost can be greatly reduced.
