Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a joint capable of adjusting a scaffold level of a building or the like.

[0002]

2. Description of the Related Art Conventionally, a scaffold of a building is provided with a base jack on a base of the scaffold pipe in order to eliminate a height difference and a step of the (assembled) scaffold pipe, and a joint is used to connect the scaffold pipes to be assembled. And furthermore, the anchor is driven into the building, connected to the scaffold pipe, and assembled. As this joint, there is known a joint in which arms are provided on both side end surfaces of a disc-shaped pedestal to be inserted into scaffold pipes (for example, Japanese Utility Model Laid-Open No. 5-8).
No. 9925).

[0003]

However, in the case of the building scaffold assembled by adjusting the level from the base with the above-mentioned conventionally known base jack, if the level adjustment on the base is slightly inconsistent, if the scaffold pipe is set high, The height difference and steps of the scaffold (pipe) increase as the assembling increases, the scaffold loses its balance, and the danger of work increases,
It is difficult to correct the height difference, step and imbalance of the (assembled) scaffold pipe by adjusting with the base jack or anchor.

[0004] It is an object of the present invention to provide a joint having a simple structure which can securely connect and fix scaffold pipes (to be assembled), and can adjust the level of a scaffold such as a building arbitrarily.

[0005]

In order to achieve the above object, the present invention provides a first scaffold pipe which is inserted into a scaffold pipe perpendicular to one end face of a scaffold pipe fixing pedestal having a bolt insertion hole.
And a second arm portion to be inserted into the scaffold pipe. The screw portion has a scaffold pipe movable pedestal having a rotation hole on the outer peripheral portion screwed to the other end surface of the scaffold pipe fixed pedestal. And
In this order, a main body portion provided linearly with respect to the first arm portion, a split cover provided with bolt insertion holes for fixing a scaffold pipe inserted into the arm portion from both sides, A scaffold level adjusting joint, comprising: a bolt and a nut that penetrate a split cover and a scaffolding pipe fixing base to fix the scaffolding pipe.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a scaffold level adjusting joint according to an embodiment of the present invention. FIG. 2 is a (partial) side view showing a use state of the scaffold level adjusting joint of one embodiment of the present invention. FIG. 3 is an exploded perspective view showing an assembled state of the scaffold level adjusting joint according to one embodiment of the present invention.

A scaffold level adjusting joint according to an embodiment of the present invention shown in FIG.
A main body 1 having a first arm 3 provided on one end surface thereof, a screw portion 5 having a scaffolding pipe movable pedestal 6 screwed on the other end surface thereof, and a second arm portion 4; Cover 9a, 9b (9)
And a bolt 11 and a nut 12 for fixing them.

[0008] The fixed base 2 for the scaffolding pipe includes a first arm 3
The scaffold pipe 13 (b) has a disk shape having a side end surface larger than the inner diameter of the scaffold pipe 13 so that the scaffold pipe 13 (b) can be received. The scaffolding pipe fixing pedestal 2 is provided with a bolt insertion hole 7 penetrating in the diameter (direction) of the disk.

On one side end surface of the scaffolding pipe fixing base 2,
A first arm 3 is fixedly mounted perpendicular to the diameter direction of the disk. The arm 3 has an outer diameter slightly smaller than the inner diameter and a rounded tip so that the scaffold pipe 13 (b) can be smoothly inserted and securely fixed. It has a cylindrical shape with a moderate length.

On the other end surface of the scaffolding pipe fixing pedestal 2, that is, the surface opposite to the surface on which the first arm portion 3 is provided, a screw portion 5 is provided.
Is fixed. A movable base 6 for a scaffold pipe is screwed into the screw portion 5. Movable pedestal 6 for scaffolding pipe
This is also a donut-shaped disc having a side end surface larger than the inner diameter of the scaffold pipe 13 so that the scaffold pipe 13 (a) inserted into the second arm 4 can be received. A female screw which is screwed into the male screw of the screw portion 5 is formed on an inner peripheral portion of the donut-shaped disk, and a (sharp tip) is formed on the outer peripheral portion.
A hole 8 for inserting a rod to rotate the movable base 6 is provided.

A second arm 4 is fixedly mounted on the tip of the screw 5. The arm 4 also has an outer diameter slightly smaller than its inner diameter and a rounded tip so that the scaffold pipe 13 (a) can be smoothly inserted and fixed securely. It has a cylindrical shape with a moderate length.

The screw 5 and the second arm 4 are formed linearly in this order with respect to the first arm 3. That is, in the main body 1, the first arm 3, the fixed pedestal 2, the screw 5 (with the movable pedestal 6 screwed), and the second arm 4 are linearly and integrally formed in this order. It was done.

The split cover 9 includes two covers 9 having bolt through-holes 10a and 10b near the center, respectively.
a and 9b. The two covers 9a and 9b are combined to form a cylindrical shape, and the inner diameter is almost the same as the outer diameter of the scaffold pipe 13. The length of each cover 9a, 9b is
Scaffold pipes 13a, 13a,
The length is such that the scaffold pipes 13a and 13b can be securely fixed when the 3b is inserted.

The bolt 11 can be inserted into the rotation hole 10a, the bolt insertion hole 7 and the rotation hole 10b, and the nut 1
It is a length and strength that can be securely fixed by tightening at 2.

Next, assembly of a scaffold such as a building using the scaffold level adjusting joint will be described. First, the scaffold pipe 1 is attached to the screw of the base jack 14.
The lower end of 3 (a) is inserted and a first-stage scaffold pipe is assembled. Next, the second arm 4 of the main body 1 is fitted into the upper end of the first-stage scaffold pipe 13a, and the lower end of the second-stage scaffold pipe 13b is further inserted into the first arm 3 of the main body 1. Is inserted. A sharp-pointed rod is inserted into the turning hole 8 of the movable base 6 for the scaffold pipe, and the rod is rotated to make the first-stage scaffold pipe 1
The distance between 3a and the second-stage scaffold pipe 13b is appropriately adjusted. After the gap is adjusted, the cover 9 is split from both sides of the scaffold pipes 13a and 13b so that the rotation holes 10a and 10b are aligned with the positions of the bolt insertion holes 7 of the fixing base 2 of the main body 1.
a, 9b are applied, the bolt 11 is inserted through the rotation hole 10a, the bolt insertion hole 7, and the rotation hole 10b, and the nut 12 is screwed and tightened, and the first stage scaffold pipe 13a and the second stage The scaffold pipe 13b is connected and fixed. In a similar procedure,
First-stage scaffold pipe 13a and second-stage scaffold pipe 1
3b, a scaffold level adjustment joint is installed sequentially,
The second stage scaffold pipe 13b is assembled. By repeating this procedure, the scaffold pipes 13 are assembled to the required height, and the scaffold is horizontally assembled.

[0016]

As described above, in the scaffold level adjusting joint of the present invention, the distance between the scaffold pipes can be appropriately adjusted by the movable pedestal, and the scaffold pipes can be securely fixed by the split cover. Can be connected and fixed. Therefore, by using the scaffold level adjusting joint of the present invention, a high scaffold such as a building can also assemble a passage horizontally and at a passage height according to the needs of the worker and the work. That is, for the first time according to the present invention, it has become possible to provide a joint having a simple structure in which scaffold pipes (to be assembled) can be reliably connected and fixed to each other, the level of the scaffold can be arbitrarily adjusted, and the structure can be simplified.
