Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting hollow extruded profile members in a gate.

[0002]

2. Description of the Related Art As shown in FIG. 7, for example, in an iron gate (41) made of H-shaped steel, a mountain-shaped portion at the center of the upper portion thereof is used.
To configure (42), the horizontal member (43), the tilting member (44), and the tilting member (44) that are adjacent to each other are connected by welding.

Further, as shown in FIG. 8, in the gate (45) made of extruded aluminum, horizontal members adjacent to each other are provided.
(46), the tilting member (47) and the tilting member (47) were connected to each other by three joints (49), (49) and (50) made of aluminum alloy castings.

[0004]

Among the conventional connecting structures described in the preceding paragraph, in the former, the finishing treatment such as welding the members together and polishing the welded portions to adjust the appearance of the welded portions is performed. Since it is necessary, there is a problem that the connecting work is troublesome.

On the other hand, in the latter case, although welding work is not necessary, the connection of the aluminum alloy casting joints (49), (49) and (50) does not look good, and therefore the appearance of this type of gate is improved. There is a problem of damage.

An object of the present invention is to provide a connecting structure capable of firmly and beautifully connecting hollow extruded shape members forming a gate.

[0007]

A structure for connecting hollow extruded shapes in a gate according to the present invention is a first hollow extruded shape member constituting a gate, which are adjacent to each other and which are connected to each other at a required angle. The connecting end faces of the hollow extruded shape member and the second hollow extruded shape member are butted against each other, and inside the connecting portion of both hollow extruded shape members, a V-shaped connection with a bending angle corresponding to the connection angle of these two members is formed. The member is housed, and the connecting member has one side half portion inserted into the first hollow extruded shape member and the other side half portion inserted into the second hollow extruded shape member with the bent portion sandwiched therebetween. The half part and the other side half part are integrally joined by welding, and the connecting end part of the first hollow extruded shape member and the one side half part of the connecting member and the connecting end part of the second hollow extruded shape member and the connecting member. The other half of each side is connected with a bolt.

[0008]

According to the present invention having the above-mentioned structure, the first hollow extruded shape member and the second hollow extruded shape member which are adjacent to each other are firmly connected to each other at a required angle via the dogleg-shaped connecting member. In addition, since the connecting end faces of the first hollow extruded shape member and the second hollow extruded shape member are simply butted against each other, the appearance is beautiful, and welding at the portion and finishing treatment thereafter are not necessary at all. Become.

Further, since the V-shaped connecting member has a structure in which one half portion and the other half portion are integrally joined by welding,
Just cut the joint ends of the one half and the other half in advance to the angle corresponding to the connecting angle of the first hollow extruded profile and the second hollow extruded profile, and weld the cut end faces together. The desired connecting member is easily obtained. In addition, the welding points of the one half and the other half of this connecting member are formed by butting the connecting end faces of the first hollow extruded shape member and the second hollow extruded shape member.
Since it is not visible from the outside, there is no need for finishing treatment after welding.
