After pressing and fixing the upper surface of joist B ₁ with a, upper nut
Fasten 15 to the bolt 14 to join the joist B ₁ and the H-section steel B ₂ together.

[0005]

However, in the above-mentioned conventional fitting, since unscrewing of the bolt 14 and tightening of the nuts 13 and 15 in the joining work are very complicated,
We cannot secure the safety of work performed in high places,
In addition, it has the drawback of lacking workability, and the bolt 14
Since there is a possibility that it will be loosened carelessly, there was a problem that a good joined state could not be maintained.

Further, a floor material such as a concrete panel is generally stretched on the upper surface of the joist B _1.
When it is fitted on B ₁ , the tip of bolt 14 and nuts 13, 15
Will protrude upward from the top plate 10a, and there is a limit to the strength of the bolt 14 and the thickness of the nuts 13 and 15 in terms of strength, and as shown in Fig. 7 (b). Joist B
_Although it is possible to separately form the spot facing 16 in ₁ , it is not easy to manufacture.

In addition, since the bolt 14 is used to hold the joined state of the two, a joist will be formed with the passage of time.
When B ₁ became thin, there was a great inconvenience that it could not follow this, and as a result, it could not function as a joint fitting.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to improve the work efficiency in the field and to maintain a good joined state for a long period of time. The task is to

[0009]

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a metal fitting body having a substantially U-shaped front surface, in which a leg piece 1b is formed by bending one end of a top plate 1a having an elongated through hole 2. A bending piece 1c is provided at the lower end of the piece 1b so as to face the top plate 1a.

Reference numeral 4 denotes a support shaft which is rotatably inserted in the through hole 2 of the metal fitting body 1, and has a stopper portion 5 at its head which can enter the through hole 2 of the top plate 1a. An elastic body 6, 7 consisting of a pair of upper and lower disc springs is fixed to the tip of the support shaft 4. The outer peripheral edge of the upper elastic body 6 is arranged on the top plate 1a side, and the lower elastic body is arranged. The outer peripheral edge of the elastic body 7 is arranged so as to be located on the lower side, and the elastic force of the lower elastic body 7 is set to be smaller than that of the upper elastic body 6.

When the stopper portion 5 of the support shaft 4 is engaged with the top surface of the top plate 1a of the metal fitting body 1 as shown in FIG. Top plate by the outer peripheral edge of the body 6
The back surface of 1a is configured to be pressed and biased.

This embodiment is constructed as described above, and is used to construct a building member A, for example, a pair of pipes.
The case of joining A ₁ and A ₂ will be described.

First, as shown in FIG. 2, one pipe A ₂ to be joined is placed on the bent piece 1c of the metal fitting body 1. It may In this case, even if the pipe A ₂ is receiving member of the spring piece or the like substantially U-shaped for example, on the upper surface of the bent piece 1c so as not to fall from the inadvertently bent piece 1c (not shown) provided Absent.

Then, connect another pipe A ₁ to the pipe
Place it on A ₂ . In this case, from the viewpoint of work and the like, it is preferable to set such that a slight gap is formed between the outer peripheral edge of the lower elastic body 7 and the pipe A ₁ , but even if some contact is made. No problem.

Next, if the support shaft 4 of the joining metal fitting C is rotated so that the stopper portion 5 thereof is aligned with the through hole 2 of the top plate 1a of the metal fitting body 1, the elasticity of the upper elastic body 6 is increased. Although the stopper portion 5 enters the through hole 2 of the top plate 1a by the force, the elastic force of the lower elastic body 7 is set to be smaller than that of the upper elastic body 6, As a result of the elastic body 6 pressing the lower elastic body 7 to apply a pressing force to the pipe A ₁ , both pipes A ₁ , A
₂ will be joined securely and firmly.

In this case, if the rotating jig 8 as shown in FIG. 3 is used, the support shaft 4 can be easily rotated, which is convenient. In such a rotating jig 8, a concave groove 9a capable of fitting with the stopper portion 5 of the support shaft 4 is bored in one end surface of a cylindrical jig body 9, and a pin 9b is projected on the peripheral surface on the other end side. It is provided, and the pin 9 with the concave groove 9a and the stopper portion 5 fitted is
A turning force is applied to the jig body 9 via 9b to rotate the support shaft 4.

Since the series of joining work is very simple, work at a high place can be performed safely and efficiently.

In the above embodiment, two pipes are used.
Although the case of joining A ₁ and A ₂ has been described, the present invention is by no means limited to this, and is applicable to the case of joining a square bar A as shown in FIG. The type and number of members A do not matter. For example, if the shape of the metal fitting body 1 is changed, the joists A ₁ and H-section steel A ₂ are as follows.
It is also possible to join and.

That is, as shown in FIG. 5, the metal fitting body 1 is formed in a gate shape composed of a top plate 1a and a pair of leg pieces 1b hanging from both ends thereof, and locking means is provided on the lower end side of each leg piece 1b. Notch 3 as
To provide. The other structure is similar to that of the above embodiment.

H formed as a frame of the building
After placing a plurality of joists A ₁ crossing the shaped steel A ₂ with a predetermined interval, a metal fitting C is attached at a predetermined position of the joists A ₁ as shown in FIG.
Engaging the fitting body 1 is externally fitted, the notch 3 of gold tool main body 1 is slid to the H-shaped steel A ₂ side of the H-shaped steel A ₂ Flange A ₂ 'of the fitting body 1 of the leg 1b Then, the joist A ₁ and the H-section steel A ₂ may be joined by the pair of elastic bodies 6 and 7 in the same manner as in the above embodiment.

In this way, after joining the joist A ₁ and the H-shaped steel A ₂ by using the plurality of joint fittings C, a floor material made of a concrete panel or the like is placed on the top plate 1a of the joint fitting C. In this state, the floor material and the joist A ₁ are joined with a nail or the like.

In this case, since the stopper portion 5 of the support shaft 4 is submerged in the top plate 1a of the metal fitting body 1, the elastic bodies 6 and 7 made of disc springs are bent in the vertical direction, so that the metal fitting body is 1 amount of projection from the joists a ₁ is small, therefore even without forming a separate counterbore to joists a _1, does not hinder the stretched flooring or the like into joists a _1.

Also, a pair of upper and lower elastic bodies 6 and 7 are used to join the joist
Since it holds A ₁ under pressure, even if the joist A ₁ becomes thin over time, the elastic force of both projectiles 6 and 7 makes it possible to follow it sufficiently, and There is also an advantage that a good bonding state can be maintained.

[0028] It should be noted that the resilient body 6 and 7 have the name not necessarily have to be composed of a disc spring.

Other than that, the design of the top plate 1a of the metal fitting body 1 and the shape of the support shaft 4 and the specific configuration of the locking means can be arbitrarily changed within the scope intended by the present invention.

[0030]

As described above, according to the present invention, other building members are locked to the locking means provided on the leg of the metal fitting body, and at the same time, on the back side of the top plate of the metal fitting body. Since a building member to be joined by a pair of upper and lower elastic bodies arranged is pressed to the other building member side to join, a conventional joining member is simply joined by screwing in and out of a bolt. Compared with the ones, it is possible to simplify the joining work in the field, and it is possible to obtain a special effect that work in high places can be performed safely and efficiently.

Further, by adopting a pair of elastic members, even if the building member to be joined has a property of becoming thin with the passage of time like wood, the elastic force of the elastic members is increased. Since this can be followed by this, there is also a peculiar effect that a good joined state can be maintained for a long period of time.

Further, since the joint fitting according to the present invention has a very simple overall structure as described above, it has a practical effect that it can be manufactured easily and at low cost.
