Description

[Detailed description of the invention] <Industrial field of application> When constructing the frame material or beam material of a greenhouse using pillars, this invention can adjust the length of the pillars arbitrarily and at the same time, The present invention relates to a connecting device for a strut and a striated body suitable for use when connecting striated bodies for holding stakes, leaves, etc.

<Conventional technology> Generally, in a greenhouse, a large number of strings, ropes, wires, etc., are installed above the inside of the greenhouse, and the vines, stakes, leaves, etc. of plants grown from underground are held in these strings. are doing. At this time, the ends of the filament bodies are directly connected to the frame members standing on the gable and wall surfaces.

On the other hand, when assembling external framework materials such as the gables or walls of a greenhouse, vertical construction materials that cross the horizontal members are erected, and the upper part of this construction material is connected to an arch shape through joints, etc. The lower part is held in the ground or concrete foundation.

However, the size, height, width of the greenhouse,
Since the spacing between the columns varies, and the length and thickness of the construction materials and horizontal members are not constant, the pipe columns 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 up and insert it inside to make it stand up.

<Problems to be solved by the invention> However, first of all, when constructing striated bodies such as wires and ropes inside a greenhouse as described above, the work is done separately from the processing work of the frame materials. This results in duplication of work and significantly lower work efficiency. On the other hand, when assembling frame materials such as the gable side of a greenhouse, cutting the supports to the desired length each time is inefficient and wastes material, and it is difficult to replace the supports if they corrode during use. The work is difficult, the assembly work using scaffolding is difficult and dangerous, the work of assembling while adjusting the length between the underground and upper joints is troublesome, and the installation work with the joints is difficult. There were some problems such as being troublesome and difficult.

Therefore, the purpose of the present invention is to be able to adjust the length of the strut and attach the striated body at the same time, and furthermore, when adjusting the length of the strut, there is no need to cut the strut each time, and a part of the strut can be removed. A connection between the strut and the striated body that does not require replacement even if it corrodes, does not require scaffolding when adjusting the length, maintains strength, is easy to process, and significantly improves installation workability. The purpose is to provide equipment.

<Means for solving the problem> In order to achieve the above purpose, the structure of the present invention is as follows.
An inner cylinder is inserted into an outer cylinder to form a strut, a notch is provided at an arbitrary position in the outer cylinder, and a clamping member for holding the outer cylinder and a wedge for insertion formed on the clamping member are provided. It has a hole, an attachment part also formed on the clamping member, and a wedge driven into the wedge insertion hole, the wedge is driven into the wedge insertion hole, and the end surface of the wedge is brought into contact with the outer surface of the inner cylinder, In addition, the filament body is coupled to the attachment portion.

<Function> 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 passes through the notch and contacts the outer surface of the inner cylinder, and the outer end surface of the wedge also presses the wedge into place. The outer cylinder and the inner cylinder are joined together because they abut against the inner ends of the holes and stick to each other, and at this time, the attachment portions of the filament bodies are projected outward from the struts.

<Example> Hereinafter, an example of implementation of the present invention will be described with reference to the drawings.

FIG. 1 shows a device for connecting a strut and a wire body according to a preferred embodiment of the present invention.

The strut 1 consists of a main strut 2 as an outer cylinder and an auxiliary strut 3 as an inner cylinder. That is, the support 1 has a hollow main support 2 which is an outer cylinder made of a cylindrical pipe, and an auxiliary support 3 which is an inner cylinder made of a cylindrical pipe that is slidably inserted into the main support 2. The length of the pillar 1 is adjusted by adjusting the height by expanding and 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. Further, the inner cylinder and the outer cylinder may be square prism pipes or other polygonal pipes.

In the embodiment shown in FIG. 1, the main support 2 is located below,
Although this is inserted into the ground, the auxiliary support 3 may be placed 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 rotation direction at an arbitrary position of the main strut 2, preferably near the end. It penetrates from the outside to the inside.

The first set of notches 4 consists of openings a, b, and c formed in a groove shape along the circumferential direction, and the second set of notches 5 and the third set of notches 6 also have groove-shaped openings. It consists of parts d, e, f and g, h, i.

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

With the notches shown in Fig. 3, only one set of notches may be used depending on the thickness and shape of the wedge.
It is possible to connect the columns using two or three sets of upper and lower notches.

The clamping member 10 includes a main body 10a, a pair of opposing support pieces 11, 11 connected to the main body 10a, and
The supporting pieces 11, 11 have a pair of opposing wedge insertion holes 12, 12 and holes 19, 19 serving as attachment portions for the filament body.

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. However, the wedge 13 is not limited to this, and may be provided with a stopper on the side surface, a groove for preventing slipping on the end surface, or a columnar shape.

In the embodiment shown in FIG. 1, a wedge 1 is inserted into the wedge insertion hole 12.
3, the legs 15, 15 pass through the first set of notches 4 and the second set of notches 5, or pass through the second set of notches 5 and the third set of notches 6. penetrate. However, if the wedge 13 is thin and has one leg, only one set of notches may be used.

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

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 4, 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 FIG.
At the same time, the tapered surface 16 of the wedge 13 abuts the outer surface of the auxiliary strut 3, and the auxiliary strut 3 and the main strut 2 push against each other via the wedge 13, so that the auxiliary strut 3 is optionally held on the main post 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. At this time, holes 19 and 19 are
The wires are located in the horizontal direction of the hole 19,
Ropes, strings, ropes, wires, chains, and other striatum 20
are combined. These filamentary bodies are molded from metal, synthetic resin, fiber, or the like.

By the way, as shown in Fig. 3, the notches 4,
Since there are multiple cutouts 5 and 6 facing in the circumferential direction, no matter which direction the main support 2 is facing, one of the notches will be facing the front or almost the front, so insert the wedge. If the worker 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 positioned facing the operator. There is no need to move it.

The support 1 using the above-mentioned outer cylinder 2 and the clamping member 10 is used, for example, as a construction material for the gable side B or wall C of a vinyl house A as shown in Fig. 4, or as a frame material as an arch-shaped main support. be done. Similarly, it can be used as a frame material in general buildings, ladder supports, wisteria trellises, grape trellises, etc., and has a wide range of applications.

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

On the other hand, holes 19 provided in the clamping member 10 protrude inward from the greenhouse A, and a large number of filamentary bodies 20 connected to the holes 19 are constructed inside the greenhouse A, grow from the ground, and extend upward. The vines, bushes, and leaves of plants are entangled with the striatum 20 and held there.

In the above example, an example was explained in which it was used for the frame material and beam material of a greenhouse, but this device is used for the main support that is the vertical frame material of a wisteria trellis or grape trellis, etc., and the wire installed on this support. used,
It is possible to hold rattan vines, grape vines, etc. on the wire.

<Effect of invention> According to the present invention, the following effects are achieved.

(a) The length of the struts can be adjusted and the striatum can be connected at the same time.
Workability is significantly improved, and no special metal fittings are required to connect the filament bodies.

(b) If 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. You can drive a wedge from there.

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

(d) If a part of the outer cylinder or insert is broken or corroded, that part can be cut off and the cut length can be easily corrected.

(e) The struts only need to expand and contract depending on the mounting position, and since they are not cut each time, there is no waste of material and no cutting work is required.
