[0002]

2. Description of the Related Art Conventionally, as a U metal fitting / wedge tightening type cross pipe connecting metal fitting, a pipe fitted in a concave portion of a metal fitting bipod plate is substantially orthogonal to a pipe inserted in a curved portion of the metal fitting. There are only those that have the function to conclude.

That is, in the conventional metal fitting of the above-mentioned type, effective wedge tightening can be obtained unless the concave recess of the metal fitting bipod plate is substantially perpendicular to the pipe inserted in the metal fitting curved portion. It is a structure that cannot be used.

Thus, the conventional U metal fitting / wedge tightening type cross pipe connecting metal fitting is used for connecting a vertical pipe in a frame such as a vinyl house formed on a slope of a mountainous area and a horizontal pipe inclined along the slope. Does not work. Even if the concave part of the metal fittings bipod plate is formed by shifting between the bipod plates so as to respond to the inclination angle of the horizontal pipe, it is only because the crossing angle of the horizontal pipe with respect to the vertical pipe changes, and Pipes cannot be joined at variable crossing angles. It is possible to set up a vinyl house, more properly, for farming and horticultural work.
Although the degree and the angle range are not necessarily wide, there is a problem that it is not possible to meet the demand of the vinyl house slope construction unless a considerable number of types of metal fittings are prepared.

Conventionally, a universal joint type or substantially similar cross pipe fitting is also known, but this is different from the U fitting / wedge tightening type fitting, and a simple operation of hammering the cross pipe into a cross pipe. Can't combine.

[0006]

The problem to be solved by the present invention is to use one kind of one, and to install a horizontal pipe in a vertical pipe of a frame of a vinyl house or the like, depending on the tilt angle at which the horizontal pipe can be cultivated and horticultural work can be performed. , Inclined at various angles with medium inclination,
The purpose is to develop a U metal fitting that can be firmly connected and a wedge tightening type cross pipe fitting.

[0007]

In order to solve the above problems, the cross pipe connecting metal fitting of the present invention has a first pipe inserted into a curved portion of a metal plate U-shaped bending metal fitting, and is attached to a bipod plate of the metal fitting. A second pipe is fitted in the formed concave portion so as to intersect the first pipe with a space therebetween, and these pipes are tightened by a wedge. A substantially middle region of a side edge of the one concave portion of the leg plate on the tip side of the same leg plate extends in the width direction of the leg plate at a frontage corresponding to a radius of the concave portion, and an inlet side region following the intermediate region is the intermediate region. Is narrowed narrower and is formed in a larger shape toward the inlet side from the other recessed portion, and the portion corresponding to the inlet side region of the side edge on the tip side of the leg plate of both recessed portions, the bottom and the opposite side. At the middle part of the side edge of the It is the most important feature that the wedge groove recessed outward is formed.
