Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structural support material for a greenhouse, which is a framework of the greenhouse.

[Prior Art] Many of the conventionally used greenhouse structural pillars have a circular cross section, and the circular cross section is the most inexpensive and easily available material.

[Problems to be solved by the invention]

However, such a circular cross section has a problem that the bending strength and the strength against compressive stress are not sufficient, and when the structural support members of the cross section having the circular cross section are tightly connected, they are not crossed with the tightening fastener. There is a problem that the contact surface with the existing strut material comes into contact with each other in a circular cross section and slips occur at the contact portion, so that the tightening joint portion is not stable.

The present invention solves the above problems, and an object thereof is to provide a strut material for a greenhouse structure, which has sufficient strength and is capable of forming a stable and strong joint with a crossing strut material. It is what

[Means for Solving the Problems] In the greenhouse structural strut material of the present invention, a tubular body having a concave groove on one side along the longitudinal direction has a triangular top with the concave groove facing outward. Is formed in an arch frame, and a cross strut material is attached to the lower surface of the arch frame so as to be orthogonal to each other. The recess of the tightening coupler having the notch for inserting the material and the engaging portion at the lower part is brought into close contact with the groove of the tubular body, and the cross strut material is fitted in the notch, and the engaging portion and the cross strut are provided. A wedge material is inserted between the material and the material.

[Action]

Since the tubular body was formed on the arch frame with the groove facing outward,
The strength against external pressure is increased, and the tightening connection between the cross strut member attached to the lower surface of the arch frame and the arch frame can be stably and firmly connected.

〔Example〕

 Next, an embodiment of this invention will be described with reference to the drawings.

As shown in FIG. 1, on one side of the tubular body 1, concave grooves 2 are provided along the longitudinal direction of the tubular body 1, and the concave grooves 2 are provided with nail holes 3 at appropriate intervals. ing. The tubular body 1 is formed by bending the concave groove 2 toward the outside to form an arch frame 4 having a triangular top as shown in FIG.

In FIG. 1, reference numeral 5 is a cross column member, which is a rod-shaped member which is attached orthogonally to the lower surface of the tubular body 1 forming the arch frames 4 arranged side by side and which is tightly coupled to the tubular body 1. is there.

In FIG. 1, 6 is a tightening connector for tightening and connecting the tubular body 1 and the cross strut member 5, and the tightening connector 6 is a second member.
As shown in the figure, the central top portion is provided with a concave portion 7 having a shape that comes into close contact with the concave groove 2 of the tubular body 1 from the outside,
Both sides of the central apex hang downward and are provided with notches 8. As shown in FIG. 1, the notch 8 has a size suitable for tightly fitting the cross strut member 5. The lower portions of both sides of the tightening connector 6 which are hung down are bent inward to provide locking portions 9.

When the tubular body 1 forming the arch frame 4 and the cross strut member 5 attached orthogonally to the lower surface of the tubular body 1 are fastened together, the fastening fastener 6 is attached from above the tubular body 1. The fitting support 6 is pushed down while being fitted and the cross strut member 5 is fitted into the cutout 8 so that the recess 7 of the tightening support 6 contacts the recessed groove 2 of the tubular body 1.

Next, the wedge material 10 is placed on the locking portion 9, the wedge material 10 is driven into the lower surface of the cross strut material 5, and the wedge material 10 is inserted between the locking portion 9 and the cross strut material 5, so that the tightening connection is achieved. The concave portion 7 of the tool 6 is the tubular body 1
The cross strut member 5 is in close contact with the concave groove 2 and the cross strut member 5 is in close contact with the lower side of the tubular body 1, so that the tubular body 1 and the cross strut member 5 are stably and firmly tightened in a state of being orthogonal to each other.

After the arch frames 4 arranged side by side in this manner and the cross strut members 5 orthogonal to the arch frames 4 are firmly and tightly coupled, a vinyl sheet 11 is formed on the outside of the arch frame 4 as shown in FIG.
Attach it to the greenhouse.

FIG. 8 is a perspective view of the pressing plate 12 used for attaching the vinyl sheet 11 to the outside of the arch frame 4,
A band-shaped concave portion 13 is provided in the central portion in the longitudinal direction, and nail holes 14 are formed in the central portion at the same intervals as the nail holes 3 of the tubular body 1.

On the outer side of the tubular body 1 forming the arch frame 4, FIG.
Place the vinyl sheet 11 as shown in FIG. 5 to FIG. 7, and press the pressing plate 12 from the outer surface of the vinyl sheet 11.
The strip-shaped recess 13 is abutted so as to fit into the recessed groove 2 of the tubular body 1. Then, the nail 15 is driven into the nail hole 3 of the tubular body 1 through the nail hole 14 of the pressing plate 12 and the vinyl sheet 11,
The pressing sheet 12 fixes the vinyl sheet 11 to the outside of the tubular body 1.

For rainwater, nail plate 14 of holding plate 12, vinyl sheet 11
It passes through the hole drilled with the nail 15 and the nail hole 3 of the tubular body 1, flows into the inside of the tubular body 1, is discharged from the lower end of the tubular body 1 formed in the arch frame 4, and rainwater enters the greenhouse. Does not invade.

[Effect of device]

The tubular body having a circular cross section without a groove and the tubular body having a plurality of grooves along the longitudinal direction have both weak strength and insufficient strength against external pressure. Is provided with a concave groove 2 only on one side along the longitudinal direction, and the arch frame 4 has a triangular top with the concave groove 2 facing outward.
Since it is formed, the buckling strength does not decrease and the strength against external pressure is increased.

Further, the recess 7 of the tightening connector 6 is brought into close contact with the groove 2 of the tubular body 1 and the cross strut member 5 is fitted into the notch 8 so that the cross strut member 5 of the tightening connector 6 and the cross strut member 5 are inserted. Since the wedge member 10 is inserted, there is an effect that the tubular body 1 and the cross strut member 5 can be easily and stably connected.
