In this embodiment, the setting is made such that

Reference numeral 5 denotes a boss protruding from the lower peripheral surface of the arm portion 2, and a screw hole as a mounting portion 6 is formed in the axial direction of the boss.

The axis p of the arm 2 and each of the mounting portions 3, 6
Are set so as to intersect at a point O on the axis t of the joint body 1.

Reference numeral 7 denotes one lid fitted to the small-diameter portion 1a on one end side of the connector body 1, and an insertion hole 9 is formed at the center of a circular concave portion 8 formed in the center of the upper surface as shown in FIG. Has been drilled. Reference numeral 10 denotes the other lid fitted to the other end side small diameter portion 1a of the connector body 1. As shown in FIG. 4, an insertion hole 12 is formed in the center of a substantially hexagonal concave portion 11 which is recessed in the center of the lower surface. Has been established.

Numeral 13 denotes a bolt inserted into the connector body 1, and both ends of the bolt are inserted into the insertion holes 9, 12 of the lids 7, 10, respectively, and nuts 14 are screwed into each other. Lid
The rotation is prevented by fitting into the recess 11 of the ten, and it is provided for the convenience of the screwing.

The present embodiment is composed of the above-described specific items. Next, a case where the basic unit A is assembled by using this to stretch the stretching member 16 between the compression members 15 composed of, for example, three pipes is used. Will be described.

First, as shown in FIG. 5, both ends of the compression member 15 are fitted and connected to the connecting portion 2a of the arm 2 of the connector body 1,
The three compression members 15 are arranged to intersect.

Thereafter, a tension member 16 is stretched between the joining body 1. The following three types of tension members 16 are used.

That is, the first tension member 16a shown in FIG. 6 is formed of a rod-like body having hemispherical heads 17 at both ends, and is provided between three joints B arranged in the vicinity as shown in FIG. To the triangular plane X
The head 17 of the first tension member 16a is attached to the notch 4 of the joint body 1.

The second tension member 16b shown in FIG.
A wire 19 having a screw rod 18 at each end, and a connecting rod 22 having a hemispherical head 20 at one end and a male screw portion 21 at the other end.
And the male screw portion 23 of the connecting rod 22 and the screw rod of the wire 19.
18 comprises a turnbuckle 24 which can be screwed, and a connecting rod 26 having a hemispherical head 25 is provided at the other end of the wire 19 in place of the screw rod 18 as shown in FIG. Third stretch material 16c
It is.

As shown in FIG. 5, this third tension member 16c is stretched between the other three joints B so as to form a triangular plane Y opposite to the triangular plane X. The heads 20, 25 of the connecting rods 22, 26 are mounted in the notches 4. Then, the lids 7 and 10 are fitted to the small diameter portion 1a of the connector body 1.

The second tension member 16b is inserted into the mounting portion 3 such that the head 22 of the connecting rod 22 is disposed inside the connector body 1, and the screw rod 18 is connected to the other connecting member. The components B are respectively screwed and attached to the mounting portions 7 provided on the arm portion 2 of the tool B.

Then, when tension is introduced into the tension members 16b, 16c by the turnbuckles 24 of the second and third tension members 16b, 16c, a basic unit A capable of self-supporting can be formed.

Thus, the tension members 16a, 16c have their heads 17, 20.
Can be attached to the notch 4 of the connector main body 1, for example.
Since the series of operations for assembling the basic unit A by stretching the tension member 16 can be performed very easily, there is an advantage that it can greatly contribute to shortening the construction period without burdening the operator.

Further, since the compression member 15 and the joint B are formed separately, the tension of the tension member 16 of the basic unit A can be easily controlled. It can also be used for flights.

Further, the axis p of the arm 2 of the connector body 1
The central axes q and s of the mounting parts 3 and 6 and the central axis r of each notch 4
Are set so as to intersect at one point O on the axis t of the joint body 1, so that no bending stress is generated in the joint B, and the stretching state of each stretching material 16 is maintained for a long time. The basic unit A itself has a very strong and stable structure.

Further, by joining the tension members 16 via the joints B, the appearance of the basic unit A can be maintained in good condition.

A plurality of such basic units A are connected to form a frame structure C, and the frame structure C shown in FIG. The compression member 15 is also used as one compression member 15 of another basic unit A to be continuously connected, whereby the total number of the compression members 1 can be greatly reduced. Thus, the weight of the entire structure can be reduced, and the cost can be greatly reduced.

When a long bolt 13 is used so that its tip protrudes from the lids 7, 10 to the outside, the bolt 13 is used to connect a roofing material, a wall material, or the like. It is possible.

In the above embodiment, the basic unit A is constituted by three compression members 15, but the basic unit A may be constituted by using more than four compression members 15, for example. I do not care.

When the turnbuckle 24 is provided on the tension member 16 as in the above embodiment, it is possible to facilitate the assembly of the basic unit A. However, the compression member 15 and the tension member 16 are previously fixed. It is also possible to form the basic unit A by forming the dimensions and applying an external force during assembly, and in this case, the turnbuckle 24 may be omitted.

Further, the shape of the basic unit A is not limited to the above embodiment, and the arrangement of three or more compression members 15 and the compression member
The basic unit A having various shapes can be formed by changing the form of stretching of the stretching material 16 to 15.

Further, the one lid 10 need not be used if not particularly required.

In addition, the number of the notches 4 of the connector body 1 and the configuration of each portion of the connector B including the mounting portions 3 and 7 can be freely changed within the range intended by the present invention.

[0035]

As described above, the use of the connector according to the present invention makes it possible to easily assemble a basic unit and to construct a frame structure by connecting the basic units in a simple manner. I came to.

Also, since a series of operations for assembling the basic unit by stretching the tension member on the connector can be performed very easily, for example, the head of the tension member may be attached to the notch of the connector body. Therefore, there is an effect that it can greatly contribute to shortening the construction period without putting a burden on the worker.

Further, since the compression member and the connector are formed separately, the tension of the tension member of the basic unit can be easily controlled, and this can facilitate the operation of assembling the basic unit. It will also be.

Furthermore, since the axis of the arm of the connector body, the center axis of each mounting portion and the center axis of each notch are set to intersect at one point on the axis of the connector body, the connector No bending stress is generated, and the tension state of each tension member is reliably maintained for a long period of time, so that the basic unit itself has an effect of having a very strong and stable structure.

Further, by joining the tension members via the joint, an effect that the appearance of the basic unit can be maintained in a good condition can be obtained.
