DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe fixing metal fitting for fixing a column-shaped support pipe and a girder pipe which constitute a framework of a greenhouse at end portions thereof.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional pipe fixing fitting at the end of a greenhouse is provided with a gate below both side walls of a plate having a U-shaped bent portion 31 for holding a girder pipe 5. As shown in FIG. Notch 32 through which the shaped support pipe 2 is inserted,
An inner bent portion 33 was provided at the lower end of each side wall, and after inserting the girder pipe 5 and the gate-shaped support pipe 2, a wedge 34 was driven from the front of the holding bracket to fix both pipes.

[0003]

In the above conventional pipe fixing bracket, when a vinyl sheet is stretched after forming a frame of a greenhouse, the end of the girder pipe 5 and the end of the wedge 34 are more likely than the holding bracket. If it protrudes, the vinyl sheet is broken at the end of the girder pipe 5 or the end of the wedge 34.

[0004] Even if the ends of the girder pipe 5 and the wedge 34 do not protrude from the holding fitting, they are damaged at the corners of the edge of the holding fitting. Therefore, when the vinyl sheet was stretched, a cardboard or a piece of cloth was applied to the end. or,
If the wedges 34 are not sufficiently driven, the wedges 34 may come off, the fixing fittings may come off, and the two pipes may not be fixed.

[0005] From the above point, the present invention does not damage the vinyl sheet at the end of the girder pipe or the pipe fixing bracket,
Another object of the present invention is to provide a pipe fixing metal fitting at an end of a greenhouse in which the pipe fixing metal does not come off from the pipe.

[0006]

According to the present invention, there is provided a pipe fixing bracket for holding a column-shaped support pipe.
A wall portion is formed on an extension of one piece of the plate body having the character-shaped bent portion, at which an end of a girder pipe orthogonal to the gate-shaped support pipe abuts, and an edge of the wall portion is formed with a rounded corner. At the same time, an inner bent portion having a slot at the end of the wall portion is provided, bent outward by 90 ° on the extension of the other piece of the plate body, and substantially on one side of the outer periphery near the end of the girder pipe. A holding metal fitting having a gutter-shaped portion in contact therewith, and an engaging piece bent outwardly formed along the longitudinal direction of the gutter-shaped portion on both sides of the gutter-shaped portion; At the tip of the gutter-shaped plate that abuts on one side of the outer periphery of the girder pipe from the opposite side of the girder pipe, a claw that fits into the slot of the holding metal fitting is provided, and a projection is formed inside the gutter-shaped plate near the front. And a fitting having a small hole behind the gutter-shaped plate, and penetrating into the small hole of the fitting and biting into the outer peripheral surface of the girder pipe. A fastening screw provided with a sharpened portion at the tip is screwed into the horizontal portion, and both sides of the horizontal portion are bent outwardly toward the screwing direction of the fastening screw. It is characterized by being constituted by a fastener having a hook portion bent inside to engage with the mating piece.

Further, the pipe fixing fitting according to the present invention is characterized in that an end of a girder pipe orthogonal to the gate-shaped support pipe is provided on an extension of one of a plate body having a U-shaped bent portion for holding the portal-type support pipe. The wall portion against which the portion abuts is formed, the edge of this wall portion is formed with a rounded corner, and an inner bent portion having a groove at the tip of the wall portion is provided, on the extension of the other piece of the plate body A gutter-like portion that bends outward by 90 ° and abuts one side of the outer periphery near the end of the girder pipe is formed, and horizontal pieces are formed on both sides of the gutter-like portion outward. Holding brackets,
At the tip of the gutter-shaped plate abutting substantially one side of the outer periphery of the girder pipe from the opposite side of the gutter-shaped portion of the holding metal fitting, there is a claw that fits into the slot of the holding metal fitting, and near the front of the gutter-shaped plate. A fitting having a convex portion on the inside of the trough-shaped plate, and a horizontal piece formed on each side of the gutter-shaped plate at a position facing the horizontal piece of the holding metal; a horizontal piece of this fitting and the holding metal And a fastening member inserted between the horizontal pieces.

According to the present invention having the above-mentioned structure, the end of the girder pipe can be in contact with the vinyl sheet because the holding metal fitting has a wall surface with which the end of the girder pipe abuts. Since it is not, the breakage of the vinyl sheet is prevented. Further, since the edge of the wall portion is formed with rounded corners, the vinyl sheet is not damaged even if the vinyl sheet touches the edge of the wall portion.

In addition, the fixing of the portal column pipe and the girder pipe is as follows.
The gate-shaped support pipe is held by the bent part of the holding fitting, and the girder pipe perpendicular to this is clamped by the gutter-like part of the holding fitting with the fitting, and the hook of the fastening fitting is engaged with the holding fitting. By engaging with the mating piece and tightening with the fastening screw, the abutment fitting is pushed by the girder pipe, and at the same time, the gutter-like part of the holding fitting is drawn to the girder pipe by the fastening fitting, thereby tightening both pipes. .

At the time of this tightening, since the convex portion is provided inside the fitting, the claw at the tip of the fitting fits into the slot of the holding fitting, and the rear of the fitting is tightened with a fastening screw. When pressed, a strong pressing force is applied by the leverage of the contact fitting with the convex portion as a fulcrum, and the tension becomes strong. Also, a small hole is provided in the attachment fitting, and the sharpened portion of the tightening screw protrudes from this small hole,
Since the sharp portion cuts into the outer peripheral surface of the girder pipe, the girder pipe does not come off. In addition, the provision of the small holes in the contact fitting means positioning when the fastening fitting is attached.

Next, according to a second aspect of the present invention, the holding member is provided with a wall portion and the edge of the wall portion is formed in a round shape as before, and has the same function. The fastening method is such that the gutter-like portion of the holding fitting and the fitting are pressed against the girder pipe by a fastening member inserted between the horizontal piece of the gutter-like fitting of the holding fitting and the horizontal piece of the fitting fitting. Tighten. At the time of tightening, since a projection is provided inside the attachment fitting as before, a strong pressing force is applied to the attachment fitting at the time of fastening.
