Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a building frame joint metal fitting used to connect building frames in framework scaffolding.

"Problems that conventional techniques and ideas try to solve" Conventionally, in framework scaffolding, as shown in Figure 5,
A narrow arch-shaped building frame 2 may be constructed on top of the gate-shaped building frame 1, or an arch-shaped building frame 3 with a cloth frame support shown in FIG. 6 may be constructed. These building frames are made of steel pipes.

In this case, one of the vertical members 21, 31 of the arch-shaped building frame 2 or the arch-shaped building frame 3 with cloth frame receiver is made to correspond to one of the vertical members 11 of the gate-shaped building frame 1, so that the vertical members 1
They can be easily connected by a joint pin 12 that stands up from 1.

However, the other vertical member 2 of the arch-shaped building frame, etc.
Since 2 and 32 correspond to the middle part of the cross member 13 of the gate-shaped building frame 1, a single pipe, a clamp, etc. are required for connection, and assembly and disassembly are not easy.

The present invention seeks to eliminate such conventional drawbacks.

``Means for Solving the Problems'' The present invention is designed to bend a rectangular metal plate downward at the center to form the middle part of the cross member 13 of the gate-shaped building frame 1 and the reinforcing member 14 along the cross member. An inverted U-shaped board 41 having an appropriate interval and length to span the board is provided, and a joint pin 42 that removably fits the lower end of the building frame is erected from the top surface of the board, and the board 4
A feature is that through-holes 43, 43 that communicate with each other are bored at appropriate midpoints between the two facing hanging portions in 1, and a lock pin 44 that engages with the lower surface of the cross member 13 is removably inserted into the through-holes. shall be.

``Operation'' Since the structure is as described above, the inverted U-shaped board 41 with the lock pin 44 removed is inserted from above into the intermediate part of the cross member 13 of the gate-shaped building frame 1 and the reinforcing member 14 attached thereto. The locking pin 44 is inserted across the holes 43, 43 again to engage the lower surface of the horizontal member 13, and is prevented from coming off. 22 and 32 are fitted and connected. Also, when removing it, you can remove it by following the reverse procedure.

"Embodiment" FIGS. 1 to 4 show an embodiment of the present invention.

As shown in FIGS. 1 and 2, the building frame joint hardware 4 according to the present invention is made by bending a rectangular metal plate downward at the center to form a horizontal member 13 of a gate-shaped building frame 1 and the horizontal member 13 of the gate-shaped building frame 1. An inverted U-shaped substrate 41 having an appropriate interval and length is provided to span the middle part of the reinforcing material 14 along the material, and a joint pin 42 is erected on the upper surface of the substrate by being shifted to one side. The joint pin is provided with a seat 421 at its base end, and through holes 422, 422 communicating with each other are bored at its upper end.

In addition, in the middle of both the facing hanging parts of the inverted U-shaped substrate 41, through holes 43, 43 are formed, which are shifted to the other side and communicate with each other, and the horizontal members 13 are inserted into the through holes. A lock pin 44 to be engaged with the lower surface is removably inserted, and a joint material 45 such as a chain is provided between the rear end of the lock pin and the base plate 41.

As mentioned above, move the joint pin 42 to one side,
The reason why the lock pin 44 is shifted to the other side is to avoid the reinforcing material 15 at the midpoint of the cross member 13 in the gate-shaped building frame 1.

The lock pin 44 has a flange 441 at the rear end.
In addition, a locking claw 442 that can be freely retracted is provided at the tip.

Therefore, this building frame joint hardware 4 is the third
As shown in Fig. 4, the horizontal members 13 of the portal frame 1
At the midpoint, the board 41 from which the lock pin 44 has been removed is attached to the horizontal member and the reinforcing members 14, 15 attached thereto.
from above and insert the lock pin 44 into the through holes 43, 4.
3 and install it.

Next, the arch-shaped building frame 2 or the arch-shaped building frame 3 with cloth frame receivers is erected, but at this time, the other vertical member 2
2 and 32 are fitted into the joint pin 42 standing up from the substrate 41, and the through hole 422 of the joint pin,
A lock pin is inserted into the through hole of 422 and the vertical members 22, 32 that open thereto to prevent it from coming off.

"Effect of the invention" According to the invention, the inverted U-shaped substrate 41 is connected to the horizontal member 13 of the lower gate-shaped building frame 1 and the reinforcing member 14 attached thereto.
It can be extremely easily attached to key points of the gate-shaped building frame 1 by simply extending it over the middle part of the frame and inserting the lock pin 44 into the through holes 43, 43, and since it is attached in this way, it can be held stably. In addition, since the joint pin 42 stands up from the top surface of the inverted U-shaped board 1 installed in this way, the vertical member 2 of the upper arch-shaped building frame etc. can be attached to the joint pin.
2 and 32 can be easily fitted and connected,
The vertical members 22 and 32 of the upper arch-shaped building frame can be easily and quickly assembled to the middle part of the horizontal member 13 of the lower gate-shaped building frame 1 without any trouble, and of course, when removing them, the procedure can be reversed. This makes it easy and quick to assemble and dismantle the building frame.
There is no need for a single tube or a clamp, and there is no need for the trouble and inconvenience of tightening screws, nor the risk of loosening the screws, as would be the case when using a clamp or the like.
