Description

[Detailed description of the invention] [Industrial field of application] This invention is a method for constructing frames and beams of greenhouses, general buildings, shelves, etc. using pillars, and the length of the pillars can be set arbitrarily. The present invention relates to a strut connection device suitable for use in adjusting.

[Conventional technology]

Generally, when assembling the gable or wall frame of a greenhouse, vertical building members are erected to cross the horizontal members, and the upper part of this building material is connected to the arch-shaped frame members via joints, etc. However, the lower part is held underground and in a concrete foundation.

However, the size and height of the greenhouse
The width and spacing between the supports vary, and the length and thickness of the construction materials and horizontal members are not constant, so the pipe supports used as the frame materials are cut to the desired length each time. .

For example, scaffolding is used to connect the upper part of building materials to arch-shaped frame members via joints, and holes are made in the ground to hold the lower part of building materials underground. I dig it, insert it into this hole, and make it stand up.

Furthermore, for handrails at general construction sites, telescopic scaffolding supports, or telescopic ladders, the inner cylinder can be slidably inserted into the outer cylinder, and the inner cylinder can be fixed at any position to separate the outer cylinder and the inner cylinder. The total length has been fine-tuned.

By the way, when fixing the inner cylinder to the outer cylinder at an arbitrary position, a large number of small holes are provided in each of the outer cylinder and the inner cylinder, and one of the inner cylinders is inserted into any hole in the outer cylinder. Two holes are placed opposite each other, and pins, bolts, etc. are inserted into these holes from the outside to connect the two.

[Problem that the invention attempts to solve]

However, when assembling the frame of the gable side of a greenhouse as described above, it is difficult to cut the supports to the desired length one by one, resulting in wasted material, and the supports corrode during use. If it is, it is difficult to replace it, it is difficult and dangerous to assemble it using scaffolding, it is troublesome to assemble it while adjusting the length between the joint underground and above, and the joint There were problems such as the installation work being troublesome and difficult. In addition, in general construction, when many small holes are drilled in the outer and inner tubes as described above, the strength of the hole portion decreases and the work of drilling a large number of holes is difficult. There are also problems such as the pins and bolts that are inserted into the holes are small and easily lose powder.

Therefore, the purpose of the present invention is that there is no need to cut the supports each time, and even if a part of the support corrodes, the length can be easily adjusted using the same material without having to replace each time. To provide a strut connecting device that does not require a strut, maintains its strength, is easy to process, significantly improves the workability of installation, and can always adjust the length and connect from the same direction even when the strut rotates. It is to be.

[Means for solving problems]

In order to achieve the above purpose, the configuration of the present invention is as follows:
Consisting of an outer cylinder and an inner cylinder inserted into this outer cylinder,
Furthermore, it has a clamping member for holding the outer cylinder, a hole for inserting a wedge formed in the clamping member, and a wedge driven into the hole, and a plurality of wedges are provided at arbitrary positions of the outer cylinder along the rotation direction. A notch is provided, and a wedge is driven into the wedge insertion hole while holding the holding member in the notch position, so that the end surface of the wedge passes through the notch and comes into contact with the outer surface of the inner cylinder. This is a characteristic feature.

[Effect]

When the wedge is driven in, the inner surface of the clamping part contacts the outer surface of the outer cylinder, the inner end surface of the wedge contacts the outer surface of the inner cylinder through the notch, and the outer end surface of the wedge contacts the hole for inserting the wedge. The outer cylinder and the inner cylinder are connected because they abut against the inner ends and stick to each other, and since there are multiple notches along the circumference, the wedge can be inserted from a nearly constant position without rotating the outer cylinder. I can devote myself to it.

〔Example〕

An example of implementing the present invention will be described below with reference to the drawings.

FIG. 1 shows a strut connection device according to a preferred embodiment of the present invention.

The strut 1 consists of an outer cylinder and an inner cylinder. That is, the strut 1 is composed of a hollow main strut 2 which is an outer tube made of a cylindrical pipe, and an auxiliary strut 3 which is an inner tube made of a cylindrical pipe that is slidably inserted into the main strut 2. The length of the pillar 1 is adjusted by adjusting the height by expanding or contracting the main pillar 2 or the auxiliary pillar 3. However, there are cases where the inner cylinder serves as the main support and the outer cylinder serves as the auxiliary support.

In the embodiment shown in FIG. 1, the main support 2 is located below,
This is inserted into underground G, but on the contrary, auxiliary support 3
Alternatively, the main support 2 may be positioned below and the main support 2 may be inserted above.

For example, three sets of three elongated notches 4, 5, and 6 are formed along the rotational direction at any position of the main support 2, preferably near the end, and these notches 4,
5 and 6 penetrate from the outside to the inside.

The first set of notches 4 consists of three groove-shaped openings a, b, and c formed along the circumferential direction;
The third set of cutouts 4, 5 also consists of groove openings d, e, f and g, h, i.

Therefore, the positions in the circumferential direction of the first set of notches 4 and the second set of notches 5 in the middle stage are slightly shifted, and similarly, the positions of the third set of notches 6 in the lower stage are different from the notches 5 in the middle stage. The position of is slightly shifted in the circumferential direction.

As shown in the embodiment of FIG. 6, a plurality of notches, for example, four notches, may be formed in parallel at the same position, including a first set of notches 7 and a second set of notches 8.
As shown in the illustrated embodiment, a plurality of notches 9 having a large opening area, for example three, may be provided along the circumferential direction.

Of the notches shown in FIGS. 4 and 6, only one set of notches may be used, or two sets of upper and lower notches may be used to connect the columns.

The clamping member 10 includes a main body 10a, a pair of opposing supporting pieces 11, 11 connected to the main body 10a, and a pair of opposing wedge insertion holes 12, 12 formed in the supporting pieces 11, 11. have.

The wedge 13 has two legs 15, 15 that stand up on both sides of the main body 14, and a taper 16 is formed on the end surfaces of the legs 15, 15.

In the embodiment shown in FIG. 1, a wedge 13 is inserted into the wedge insertion hole 12.
When driven in, the legs 15, 15 pass through, for example, the first set of notches 4 and the second set of notches 5, or the second set of notches 5 and the third set of notches 6. .

Therefore, first, the clamping member 10 is manually inserted into the outer periphery of the main support 2 and temporarily held.

Next, when the wedge 13 is driven into the holes 12, 12, the legs 15, 15 of the wedge 13 are guided and inserted into the notches 5, 5, and when the wedge 13 is inserted deeply, the tapered surface 16 gradually It comes into contact with the outer surface of the auxiliary support 3 while being pressed.

Therefore, as is clear from FIGS. 2 and 3, the inner end surface of the main body 10a of the clamping part 10 is in close contact with the outer surface of the main support 2, and the outer end of the main body 14 of the wedge 13 is in contact with the hole 1.
At the same time, the tapered surface 16 of the wedge 13 contacts the outer surface of the auxiliary support 3, and the auxiliary support 3 and the main support 2 are pressed against each other via the wedge 13, so the auxiliary support 3 is optional. It is held by the main support 2.
In other words, when the wedge 13 is driven in, the auxiliary support 3 is pushed in, and the auxiliary support 3 is forcibly held between the inner peripheral surface of the main support 2 and the tapered surface 16 that is the inner end surface of the wedge 13.

By the way, what should be noted here is Figure 4.
As shown in FIGS. 6 and 7, the notches 5, 6,
Since there are multiple cutouts 7, 8, and 9 facing in the circumferential direction, no matter which direction the main support 2 faces, one of the notches faces the front or almost the front, so it is not wedged. If the worker inserting the wedge is in the front, he or she can always use one of the notches to drive the wedge from the front.

Similarly, even if the operator is on the back or side, one of the notches is located on the back and side as well, so a wedge can be driven from the back or side.

In short, since one of the notches opens at any position in the circumferential direction, the wedge can be driven from any position, and the main support 2 is rotated so that the notch is in a position facing the operator each time. There is no need to move it.

The column 1 using the above-mentioned outer cylinder 2 is, for example, the 8th column.
It is used as a construction material for the gable B or wall C of a vinyl house A as shown in the figure, and as a frame material for the arch-shaped main support. Similarly, it can be used as a frame material in general construction, ladder supports, wisteria trellis, grape trellis, etc.

The frame of greenhouse A has a plurality of arch-shaped main pillars 16 erected, and the main pillar 16 is erected on the gable side B.
The construction material 17 whose top is held at the top and the main support 1
6 and a support frame 18 for attaching a seat with a narrow opening, which is installed laterally on a construction material 17. It consists of an auxiliary support column 3. The auxiliary support 3 has a clamping member 10 for the main support 2.
and wedge 13.

Note that the auxiliary support 3 in the main support 16 is bent in an arch shape.

In the above example, an example was explained in which it was used for the frame material and beam material of a vinyl house, but this device can also be used to reinforce the pillars of general buildings, frame materials for tents, towers to which scaffolding is assembled, ladders, etc. used. In addition, as shown in FIG. 9, the struts 1 of the present invention are installed in an inclined direction between the main struts 30, which are vertical framework members, and the horizontal members 31 that constitute the wisteria or grape trellis P, thereby reinforcing the trellis P. It may be used to

[Effect of idea]

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

Since multiple notches are formed in the outer cylinder along the direction of rotation, it is possible to select any of the notches and drive a wedge into the outer cylinder.This allows the wedge to be inserted from the desired position without rotating the outer cylinder. can be typed.

The outer cylinder and inner cylinder can be connected simply by driving a wedge,
It is easy to adjust the length of the strut.

If part of the outer cylinder and inner cylinder is damaged or corroded, that part can be cut off and the length of the cut can be easily corrected.

The support only needs to be expanded or contracted depending on the mounting position, and since it is not cut each time, there is no waste of material and no cutting work is required.
