2 is a perspective view showing the structure of a fixture of the present invention, and Fig.
3 is a view illustrating a state in which a first pipe and a second pipe that form the skeleton of a vinyl house are combined using the fastener of the present invention.

The following detailed description is merely an example, and is merely an example of the present invention. Further, the principles and concepts of the present invention are provided for the purpose of being most useful and readily explaining.

Accordingly, it is not intended to provide a more detailed structure than is necessary for a basic understanding of the present invention, but it should be understood by those skilled in the art that various forms that can be practiced in the present invention are illustrated in the drawings.

Fig. 1 is an exploded view of a fastener of the present invention, and Fig. 2 is a perspective view showing a fastener of the present invention. Referring to FIGS. 1 and 2, the fixture of the present invention is formed of one plate member 100. The one plate member 100 may be partitioned into two in the longitudinal direction, for example.

The first pipe coupling part 110 may be formed at the lower part of the partitioned plate member 100, for example, at the end of the first pipe 200, which is a horizontal pipe of the plastic house.

The upper portion of the partitioned plate 100 may have a second pipe coupling portion 120 to which a second pipe 300, which is an arched pipe of a vinyl house, is coupled.

The first pipe coupling part 110 may be curved in the width direction, and the first pipe 200 may be tightly coupled in the longitudinal direction to the inside of the curved part. That is, the first pipe coupling part 110 is curved along the outer diameter of the first pipe 200 in the width direction, and the second pipe 200 is tightly coupled to the inside of the curved part.

A width direction rib 112 having a semicircular cross section is formed at the lower end of the first pipe coupling part 110 to increase strength. That is, the width direction ribs 112 may protrude from the first pipe coupling part 110 in a direction opposite to a surface to which the first pipe 200 is coupled.

The width direction ribs 112 are formed on the first pipe 200 in a state where the first pipe 200 is coupled to the first pipe coupling part 110 by a load such as vibration transmitted from the first pipe 200, Thereby preventing the pipe coupling portion 110 from spreading in the width direction.

Further, at the upper and lower ends of the first pipe coupling portion 110, for example, by using a direct-coupled piece (also referred to as a direct-coupled screw or an iron plate piece) whose end portion is in the form of a drill bit, (110) may be formed with screw holes (114, 116) for coupling the first pipe (200).

Here, the position where the screw hole 114 is formed is applied to the second pipe 300 coupled to the second pipe fixing part 120 by a high load due to vibrations, twisting and the like. The screw holes 116 are formed by applying a load due to the torsion of the first pipe 200 or the like so that the screw holes 116 are formed in a position where the screw hole 114 is formed, A low load is applied to the formed position.

Therefore, the diameter of the screw hole 114 is increased to allow the direct-connected piece having a larger diameter to be fixed. The screw hole 116 is formed to be smaller than the diameter of the screw hole 114, It is preferable to fix the small direct-connected piece.

The second pipe coupling part 120 is curved in the longitudinal direction for coupling the second pipe 300, for example. For example, the second pipe coupling part 120 may be curved along the outer diameter of the second pipe 300 in a direction orthogonal to the first pipe coupling part 110, 300 are inserted.

In addition, a load distribution protrusion 122 for dispersing a load by the second pipe 300 is formed at a middle portion of the curved second pipe coupling part 120 in a direction in which the second pipe 300 is coupled As shown in Fig.

A screw hole 124 (not shown) for coupling the second pipe coupling part 120 and the second pipe 300 to each other is provided between the load distribution protrusion part 122 and the tip end part of the second pipe coupling part 120, Is formed.

A curved portion 126 curved in the direction of the second pipe 300 is formed on both left and right sides of the distal end portion of the second pipe fixing portion 120 so that the distal end portion of the second pipe fixing portion 120 .

The strength of the first pipe coupling portion 110 and the second pipe coupling portion 120 is set at both sides in the width direction of the first pipe coupling portion 110 and the second pipe coupling portion 120 The longitudinal ribs 130 may be formed.

Here, the longitudinal ribs 130 may protrude from the upper surfaces of the first pipe coupling portion 110 and the second pipe coupling portion 120. In other words, the first pipe coupling part 110 and the second pipe coupling part 120, to which the first pipe 200 and the second pipe 300 are coupled, (Not shown).

3, a plurality of horizontal pipes as the first pipe 200 and a plurality of arcuate pipes as the second pipe 300 are used to manufacture the vinyl house, The end of the first pipe 200 which meets in a T shape and the second pipe 300 are coupled to each other.

That is, according to the present invention, a portion of the second pipe 300, which meets the first pipe 200 in a T shape, is inserted into the second pipe coupling portion 120 of the fixture, So that the end of the first pipe 200 is positioned.

In this state, the operator joins the second pipe 300 to the second pipe coupling part 120 by fastening the direct coupling piece to the screw hole 124 of the second pipe coupling part 120.

The operator engages the first pipe 200 with the first pipe fixing portion 110 by fastening the straightened piece through the screw holes 114 and 116 of the first pipe fixing portion 110.

The fixture of the present invention in which the first pipe 200 and the second pipe 300 are combined as described above is mounted on the right and left sides of the first pipe coupling portion 110 and the second pipe coupling portion 120 in the longitudinal direction A longitudinal rib 130 is formed.

Therefore, even if vibrations or the like occur in the first pipe 200 and the second pipe 300 due to strong wind or the like, the first pipe coupling part 110 and the second pipe coupling part 120 may be twisted So that the first pipe 200 and the second pipe 300 can be maintained in a firmly coupled state.

In addition, since the width direction ribs 112 are formed in the first pipe coupling part 110, the first pipe coupling part 110 can be prevented from being widened in the width direction.

The present invention is characterized in that the second pipe coupling portion 120 has the load-dissipating protrusion 122 formed therein and the distal end portion thereof is curved in the direction of the second pipe 300, It is possible to prevent the phenomenon that the distal end portion is spread to the left and right.
