As shown in FIG. 8, a greenhouse generally composed of a pipe house has an arch pipe 1 standing upright from the ground, and a vertical pillar 2 on the end face side is installed on the arch pipe 1.

A joint 3 is inserted into the arch pipe 1, and an upper support piece 10 of a spacer 5 made of a C-shaped channel 9 is pivotally attached to the joint pipe 3 via a connecting tool 4 made of a bolt and a nut. The portion is removably inserted into the hollow portion 8 of the strut 2, and the spacer 5 and the strut 2 are further fixed by bolts 7 which are stoppers inserted in the locking holes 6, and the strut 2 is inserted through the joint 3 and the spacer 5. Is connected below the arch pipe 1.

[Problems to be Solved by the Invention] In the above-described strut connecting method, unless the spacer 5 is connected to the joint 3, the spacer 5 intrudes into the hollow portion 8 of the strut 2 without limitation.

For this reason, the spacer 5 may be connected to the joint 3 in advance, and then the lower portion of the spacer 5 may be inserted into the column 2 from below. However, when the space between the arch pipe 2 and the ground is small, the column The installation operation of 2 is very troublesome.

Therefore, if the spacer 5 is inserted into the support column 2 in advance and then the spacer 5 is coupled to the joint 3, the support column 2 can be easily installed even in a narrow space, but the spacer 5 can be installed when the support column 2 is erected. It falls down along the hollow portion 8. For this reason, the spacer 5 is pulled up once and then joined to the joint 3 while aligning them, so that the mounting work is troublesome and the work efficiency is poor.

Furthermore, when the spacer 5 is fixed to the support column 2 with the bolt 7 which is a stopper, the alignment of the locking hole 6 of the spacer 5 and the locking hole 6 of the support column 2 is troublesome, and fixing with the bolt 7 provides strength,
The durability is poor, and the bolt 7 may come off due to vibration such as an earthquake.

Therefore, the purpose of the present invention is to prevent the spacers inserted in the support columns from dropping, to facilitate the work of attaching the support columns to the pipe, and to easily align the spacers and the support positions. The purpose of the present invention is to provide a column connecting device having a large coupling strength between the column and the column.

[Means for Solving the Problems]

In order to achieve the above object, the structure of the present invention is provided with a stopper near the end of the spacer that engages with the end of the strut, and a stopper for fixing the spacer and the strut with a handle and a wedge provided on the handle. It is characterized in that openings for inserting wedges are formed in the body of the spacer and the body of the column, respectively.

[Action]

In the spacer inserted in the column, since the stopper engages with the end of the column, the spacer does not drop, and at the position where the stopper is engaged, the spacer can be aligned with the column and the position of the opening for inserting the wedge can also be aligned. The strength of the coupling between the spacer and the column by the wedge is strong, and the wedge cannot be removed even if there is vibration.

This strut connecting device vertically connects the strut 2 to the pipe 1, and fixes the joint 3 attached to the pipe 1, the spacer 5 having one end pivotally attached to the joint 3, the spacer 5 and the strut 2 to each other. It is composed of a stopper 11 composed of a wedge and a handle.

FIG. 6 shows an example in which the pillar 2 is vertically installed on the end face side of the pipe house by using the above-mentioned pillar connecting device.

A greenhouse A as a pipe house has a large number of arch pipes 1 standing from the ground, a pillar 2 vertically installed on the end face side of the arch pipe 1 through a joint 3 and a spacer 5, and above the arch pipes 1 and 2. It has a vinyl sheet B fixed on the front side.

On the front side of the column 2, there is a dovetail groove 12 having a narrow opening along the axial direction, and the vinyl sheet B fitted in the dovetail groove 12 is fixed via an elastic locking line C. .

The pillar 2 has a hollow portion 8 formed along the axial direction, an opening 13 along the axial direction is further formed on the back side body, and the edge of this opening 13 is formed by bending the front side inward. Legs 14, 14 are provided.

As shown in FIG. 2, the spacer 5 constitutes a main body with a C-shaped channel, a support piece 10 is erected on the upper end, a stopper 15 is provided near the end, and one or a plurality of spacers are provided on the rear surface of the body. Aperture
Forming 17,17.

The spacer 5 has bent pieces 18, 18 on the front side along the axial direction, and the stoppers 15, 15 are formed by bulging the upper ends of the bent pieces 18, 18 to the front side. The lateral width dimension of the stoppers 15 and 15 is formed to be larger than the diameter in the front-rear direction of the hollow portion 8 of the strut 2, and when the spacer 5 is inserted into the hollow portion 8, the lower end of the stopper 15 engages with the upper end of the strut 2. In addition, the spacer 5 is prevented from falling further. The front surface of the stopper 15 is curved so that it does not break even if the sheet hits it.

A hole 16 is formed in the upper side surface of the spacer 5, and this is used as a relief portion for preventing the upper portion of the spacer 5 from being deformed when the stopper 15 is bulged.

As the stopper, another member, which is longer than the width of the column 2 in the front-rear direction and fixed horizontally to the upper portion of the spacer 5 in the front-rear direction or the lateral direction, may be used.

The support piece 10 of the spacer 5 is pivotally attached to the joint 3 via a connector 4 including a bolt 19 and a nut 20. The joint 3 has a slightly cylindrical socket 21 and a holding piece 22 provided on the socket 21.

The stopper 11 is a handle 21 made of a horizontal plate and a handle 21.

The opening 17 provided in the spacer 5 has a slit 17a, and the dimension between the inner circumference of the slit 17a and the inner circumference of the opening 17 is larger than the width of the wedge 22, but the width of the opening 17 itself is a wedge. It is formed smaller than the width of 22.

Therefore, when the wedge 22 is inserted into the opening 17 through the slit 17a and then the wedge 22 is rotated through 90 degrees through the handle 21, the wedge 22 is rotated.
The back side body of the spacer 5 is sandwiched between the locking surface 24 of 22 and the legs 14, 14 of the column 2 to fix the spacer 5.

The opening of the spacer 5 may be a long hole formed along the back side body.

FIG. 7 shows a strut 2'according to another embodiment of the present invention, in which a plurality of openings 13a formed in the strut 2'are formed in the rear body portion of the strut 2'at arbitrary intervals. Thus, when the spacer 5 is inserted into the column 2'and the stopper 15 engages with the end of the column 2 ', the opening 13a faces the opening 17 of the spacer 5. Therefore, in this case, the stopper 15 is also used to align the openings 13a and 17 with each other.

[Effect of device]

 According to the present invention, the following effects can be obtained.

When the spacer is inserted into the column, the stopper engages with the end of the column, and the spacer does not fall below the position locked by the stopper. Moreover, when the wedge curved surface is formed on the front surface of the spacer, breakage of the sheet is prevented.

Since the spacers do not fall along the columns, the columns can be erected vertically with the spacers inserted in the columns, and the upper part of the spacers can be pivotally attached to the joints, so that the column erection work and the column attachment work can be performed significantly. You can improve and speed up.

It is possible to pre-dimension the opening of the strut and the opening of the spacer so as to face each other when the stopper is engaged with the end of the strut, which facilitates the alignment of the openings.

Since the support pillar and the spacer are fixed by the wedges inserted through the respective openings, the fixing strength is large and they do not loosen even when there is vibration such as an earthquake.

Since the wedge can be attached and detached by rotating the handle, operability is improved.
