Description

[Detailed description of the invention] [Industrial field of application] This invention connects an arch pipe and horizontal pipes extending in a direction intersecting the arch pipe at arbitrary intervals in a pipe house made of stretched vinyl sheets. The present invention relates to a support column connection device suitable for preventing water droplets condensed on a vinyl sheet from being transmitted to horizontal pipes and dripping into a pipe house.

[Conventional technology]

In general, a pipe house made of vinyl sheets is made by standing a large number of arch pipes, connecting multiple horizontal pipes that extend in a direction that intersects the arch pipes, and then spreading a transparent vinyl sheet over the arch pipes and horizontal pipes. Further, sheet restraining strings are placed on the vinyl sheet at arbitrary intervals, and by tightening the sheet restraining strings, the vinyl sheet is prevented from flapping and stabilized.

However, when the sheet restraint string is tightened, the vinyl sheet is pressed downward and its bottom surface comes into contact with the horizontal pipe, so the water droplets that have condensed on the bottom surface of the vinyl sheet flow down along the vinyl sheet, and these water droplets are When the pipe is transferred to a directional pipe, water droplets fall onto the plants in the pipe house from the lateral pipe, causing negative effects such as rooting of the plants, generation of disease-causing bacteria, and cracking of fruits such as strawberries and cherries.

For this reason, there have been conventionally disclosed pillar connecting devices, such as the one disclosed in Japanese Utility Model Publication No. 62-27691, which can achieve a so-called drop press effect to prevent such water droplets from falling.

The column connection device disclosed in this publication is
It consists of an inverted U-shaped column support member and a saddle-shaped wedge that is removably inserted into the column support member from the side, and the wedge is inserted between two intersecting columns supported by the column support member. The two pillars are driven in and held between the support member of the pillar and the wedge.

In this case, the two columns are separated by a wedge height, so that, for example, a vinyl sheet supported on the arch pipe does not come into contact with the transverse pipe.

[The problem that the idea attempts to solve]

However, in the above-mentioned support column connection device, since the wedge is a wedge with a general tapered surface,
This wedge can only move in the horizontal direction, and for this reason, when driving along or punching out the arch pipe, there is a risk that the hammer will hit the arch pipe and damage it or tear the sheet, making it difficult to attach and remove it. It is troublesome and difficult, and since the wedge is only inserted between two intersecting supports, its position is unstable.
There is a risk of the wedge coming off due to vibrations from the ground, etc. There is a hollow-shaped bent part on the upper surface of the wedge, and this bent part is long and makes surface contact with the arch pipe, but there is a risk of the wedge coming off due to vibrations from the ground. The friction is large, making attachment and detachment difficult. When driving a wedge laterally, the wedge may meander and enter diagonally, making it impossible to hold the two supports in a stable manner. , the lower surface of the wedge is in point contact with the lateral pipe,
There are problems such as when a large load is applied to the wedge, the lower surface of the wedge may deform.

Therefore, the purpose of the present invention is to provide a column connection device that does not damage vinyl sheets or arch pipes, allows easy and speedy column connection operations, and is stable and strong. .

[Means to solve the problem]

In order to achieve the above object, the configuration of the present invention is to provide a support for a bifurcated support column in a column connection device that connects a first column and a second column that intersect each other with an arbitrary interval. The member consists of a support member for the support pillar that is rotatably fitted into the support member for the support pillar, and the support member for the support pillar has a guide portion into which the first support pillar is inserted, and a notch into which the second support pillar is inserted. The support member of the support column has a second support member within the support member of the support support member.
a notch that rotatably fits into the support column, and when the second support column is rotated as a fulcrum through the notch,
It is characterized by having an arcuate locking surface that engages with the first support column.

[Effect]

Two struts that intersect with the support member of the strut are inserted through the guide portion and the notch, and then,
When the support member of the column fitted to the second column is driven in the rotational direction using the second column as a fulcrum, the first column is held between the guide part and the arc-shaped locking surface, and the notch in both A gap is formed between the first and second columns by the height of the support member for the column, with the second column being held between them.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a pipe house, which is a greenhouse, using the support support connection device A according to the present invention.

Pipe house B consists of a large number of arch pipes 1 that are first supports that stand on the ground, horizontal pipes 2 that are second supports that intersect with the arch pipes 1, and a sheet such as a transparent vinyl sheet spread over the arch pipes 1. 3, and the arch pipe 1 and the horizontal pipe 2 are connected via a column connecting device A.

The column connecting device A provides an arbitrary distance in the height direction between the arch pipe 1 and the horizontal pipe 2, and even if the sheet restraining string is tightened and provided on the vinyl sheet 3, this vinyl sheet 3 The lower surface does not come into contact with the horizontal pipe 2, and as a result, water droplets that have condensed on the lower surface of the vinyl sheet 3 do not come into contact with the horizontal pipe even if they flow downward, and therefore are not allowed to flow from the position of the horizontal pipe 2 onto the plants. There is no possibility of falling.

The pole connecting device A of the present invention is composed of a pole support member 4 and a pole pressing member 5 as shown in Figs.

The supporting member of the column consists of two legs 6, 6 bent in an inverted U-shape, a guide part 7 that connects the legs 6, 6, and arc-shaped notches 8, 8 provided in the legs 6, 6. The guide portion 7 is formed to have a semicircular cross section and inserts and supports the arch pipe 1 serving as the first support.
The notches 8, 8 have arcuate surfaces and allow the horizontal pipe 2 to be inserted and supported. However, it is possible to insert the lateral pipe 2 into the guide portion 7 and insert the first pipe 1 into the notches 8, 8 to use it upside down.

The support member 5 includes two bifurcated plate bodies 9, 9, notches 10, 10 formed at the bottom of the plate bodies 9, 9 that open downward, and a taper formed at the upper part on the opposite side of the notches 10, 10. shaped guide surface 11 and guide surface 11
An arc-shaped locking surface 12 connected to the plate body 9, and a stopper 1 provided at the back end of the plate body 9, which also serves as a driving allowance.
It is composed of 3.

The plate bodies 9, 9 may be formed from one thick plate instead of two plates as shown.

With the tapered guide surface 11, the plate bodies 9, 9
can be deeply inserted into the support member 4 of the column as will be described later, but it is also possible to omit this and make the entire surface an arcuate surface.

The support member 5 of the strut can be attached and detached between the legs 6 of the support member 4 of the strut by fitting the horizontal pipe 2 into the notches 10 and rotating with the horizontal pipe 2 as a fulcrum. inserted into.

That is, in a state where the arch pipe 1 is inserted into the guide part 7 of the support member 4 of the support column, and the lateral pipe 2 is inserted into the notches 8, 8, the support member 5 of the support column is inserted.
Fit the notches 10, 10 into the horizontal pipe 2, and then hit the stopper 13 counterclockwise with a hammer or the like as shown in FIGS. 2 and 4, and the plate body 9,
9 rotate in the same direction using the horizontal pipe 2 as a fulcrum. When the plate bodies 9, 9 stand up, the guide surface 11 passes under the arch pipe 1, and when the plate bodies 9, 9 stand up in the vertical position (Fig. 4), the arc-shaped locking surface 12 It comes into close contact with the lower surface of the arch pipe 1.

At this time, the plate bodies 9, 9 are forcibly driven into the supporting member 4 of the column with a hammer, so that a wedge effect is produced, and the arch pipe 1 is connected to the guide part 7 and the locking surface 12.
Similarly, the horizontal pipe 2 is strongly held between the upper and lower notches 8 and 10, and as a result, the arch pipe 1 and the horizontal pipe 2 are joined together.

Guide surface 11 when rotating support member 5
If the upper part is entirely an arc-shaped locking surface, the arch pipe 1 will be pinched before the plate bodies 9, 9 stand up vertically, and the position of the plate bodies 9, 9 will become unstable. However, if this position is ignored, the tape-shaped guide surface 11 can be used without it.

When the plate bodies 9, 9 stand vertically, the stopper 1
3 comes into contact with the outer end surfaces of the legs 6, 6, and the plate bodies 9, 9 do not rotate any further and are held in a stable state.

Arch pipe 1 and horizontal pipe 2 as above
When these are connected, there is an interval between them corresponding to the height of the support member 5, in other words, there is a notch 1 between them.
0 and the locking surface 12, and the vinyl sheet 3 does not come into contact with the transverse pipe 2 (FIG. 4).

[Effect of idea]

According to the present invention, there are the following effects.

Since the support member of the support column is struck in the rotational direction through the stopper during installation and removal, hammers, etc. do not hit the first support support or the vinyl sheet, preventing damage to the first support support and the vinyl sheet, and making the installation and removal work easy. be.

Since the support member of the support post is fitted into the second support support via the notch, its position is not shifted and is held in a stable position, and moreover, the support member enters straightly without wobbling laterally during driving.

When the support member is attached or removed, its arcuate locking surface is in close contact with the first support, but the contact surface is a point contact, and the friction between the two is small, making it possible to drive or punch out with a small force. It is easy and quick to attach and detach.

Since the inner circumference of the notch at the bottom of the support member of the support is evenly in contact with the second support, even if a large load is applied, it can be dispersed, preventing damage due to stress concentration.
Deformation can be prevented.
