Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for connecting a horizontal rod to a column which constitutes a scaffold or the like.

[0002]

2. Description of the Related Art Generally, as a structure for connecting a horizontal rod to a column, for example, as schematically shown in FIG. 5, the column A is provided with a flange B protruding outward in the radial direction.
The through hole C is formed in the
A U-shaped connecting bracket E having an upper connecting plate E1 placed on the upper surface of the flange B and a lower connecting plate E2 facing the upper connecting plate E1 with a predetermined gap is provided. Through-holes F1 and F2 facing E1 and E2
And a coupling piece G is inserted from the through hole F1 of the upper connecting plate E1 placed on the flange B into the through hole F2 of the lower connecting plate E2 through the through hole C of the flange B. By connecting the connecting bracket E to the connecting flange B via the connecting piece G, one end of the horizontal rod D in the length direction is connected to the support column A.

[0003]

By the way, in the case where the operator independently installs the horizontal rod D between the columns A and A, first, one end side of the horizontal rod D in the length direction is connected to one of the columns A. In the above, the other end in the length direction of the horizontal rod D is connected to the other strut A. When performing such work, in the case of the above-mentioned connecting structure, the horizontal rod D is connected via the connecting piece G. In the state where only one end side in the length direction of the rod is supported by the column A, there is a problem that the other end side hangs downward due to the weight of the rod D, as shown by a two-dot chain line in FIG.
When the other end side of the horizontal rod D is connected to the other post A, the other end side of the horizontal rod D is lifted and the upper connecting end E1 of the connecting bracket E provided on the other end side of the horizontal rod D is attached to the post. It is necessary to place the work on the flange B of A, and it is very difficult to perform such work especially at high places.

When connecting one end of the horizontal rod D in the lengthwise direction to the column A, first, the upper connecting plate E1 is placed on the flange B and then the connecting piece G is driven. Therefore, there is a problem that the upper connecting plate E1 placed on the flange B is accidentally detached from the flange B before the coupling piece G is driven.

The present invention was developed in view of the above circumstances, and an object of the present invention is to facilitate the work of connecting a horizontal rod to a column and to use only one end of the horizontal rod in the longitudinal direction as the column. Another object of the present invention is to provide a horizontal rod connecting structure capable of suppressing the other end of the horizontal rod from hanging down with respect to the column when connected.

[0006]

SUMMARY OF THE INVENTION In the present invention, however, a support body 3 is provided on the outer peripheral surface of the support column 1 so as to project outward in the radial direction of the support column 1, and the support body 3 is provided with the support body 3 of the support column 1. While forming a through hole 30 penetrating in the vertical direction along the outer peripheral surface, a connecting body 4 which can be inserted into the through hole 30 is provided at an end portion in the longitudinal direction of the horizontal rod 2, and the connecting body 4 is provided with the connecting body 4. An abutment surface 54 is provided on the outer peripheral surface of the support column 1 for abutting vertically, and an insertion hole 63 for the wedge 7 is formed in the connecting body 4, so that the connecting body 4 is inserted into the through hole 30. By driving the wedge 7 inserted into the through hole 30 from the insertion hole 63, the connecting body 4 is moved to the support column 1 side with respect to the supporting body 3, and the contact surface 54 of the connecting body 4 is moved to the above-mentioned. It is characterized in that it is adapted to be pressed against the outer peripheral surface of the column 1.

[0007]

According to the present invention, by inserting the connecting body 4 attached to one end side in the lengthwise direction of the horizontal rod 2 into the through hole 30 of the support body 3, one end side in the lengthwise direction of the horizontal rod 1 is set to the above-mentioned one side. The horizontal rod 1 is prevented from being inadvertently separated from the support body 3 by being locked by the support body 3, and in such a state, the horizontal rod 1 is inserted from the insertion hole 63 of the connecting body 4 into the support body 3. By driving the wedge 7 inserted into the through hole 30, the connecting body 4 moves in the direction of the pillar 1 with respect to the support body 3, and the abutting surface 54 comes into pressure contact with the outer peripheral surface of the pillar 1.
Along with this, the horizontal rod 2 is provided with the pillar 1 that is erected vertically.
It is held in a direction orthogonal to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, the present invention is applied to a connecting structure of a horizontal rod 2 which is erected between columns 1 constituting a scaffold for construction and the columns 1, and is substantially V-shaped. A support 3 made of a bent metal plate is separately formed, and the support 3
By fixing the bent end of the support to the outer peripheral surface of the pillar 1 made of a cylindrical pipe material in the middle of the length direction by welding, the support body 3 is installed radially outward of the pillar 1. The supporting body 3 is provided with a through hole 30 defined by the inner peripheral surface of the supporting body 2 and the outer peripheral surface of the supporting column 1 and penetrating in the vertical direction along the outer peripheral surface of the supporting column 1.

On the other hand, a connecting body 4 which can be inserted into the through hole 30 is provided at both ends in the longitudinal direction of the horizontal rod 2 made of a cylindrical pipe material. In the embodiment shown in the drawing, the connecting body 4 is provided. Is composed of a connecting leg 5 inserted into the through hole 30 and a fixing bracket 6 for fixing the connecting leg 5 to the horizontal rod 2.

Specifically, a pair of opposed pieces 61 facing each other.
A fixed bracket 6 having a substantially U-shape in plan view including 62 is formed, and the opposed pieces 6 of the fixed bracket 6 are formed.
By inserting the connecting sides of 1 and 62 into the slits 21 formed at both ends in the lengthwise direction of the horizontal rod 2 and fixing them by welding, the one end in the lengthwise direction of the fixing bracket 6 is fixed to the horizontal rod. It is fixed at 2.

Further, the connecting leg 5 is provided with a pair of side walls 51 and 52 facing each other and a connecting wall 53 connecting one ends of these side walls 51 and 52, and the end edges of the side walls 51 and 52 are connected to the column 1. While making a smooth contact surface 54 that vertically contacts the outer peripheral surface of the connection wall 53, the connecting wall 53 is inclined in a direction in which the connection wall 54 is separated from the contact surface 54 downward. The upper end of the connecting leg 5 is fixed to the free end of the fixed bracket 6 by welding so that the contact surface 54 is orthogonal to the lengthwise direction of the horizontal rod 2 to form the fixed bracket 6. An insertion hole 63 for the wedge 7 is provided between the facing pieces 61 and 62.

In the embodiment shown in the drawing, the lower end side of the wedge 7 is inserted into the insertion hole 63, and then the lower end portion of the wedge 6 is engaged only with the insertion hole 63.
A protrusion 71 is provided so as to prevent the wedge 7 from coming off.

Thus, in order to connect one end side in the lengthwise direction of the horizontal rod 1 to the support column 1, first, the connecting leg 5 of the connecting body 4 attached to one end side in the lengthwise direction of the horizontal rod 2 is connected to the support 3 Through hole 30
Therefore, one end of the horizontal rod 1 in the length direction is locked to the support body 3 so that the horizontal rod 1 does not inadvertently separate from the support body 3.

Contact the outer side surface of the inclined connecting wall 53 of the connecting leg 5, and the other side surface 7b of the wedge 7 contacts the inner side surface of the through hole 30. By driving the wedge 7, Since the connecting body 4 moves in the direction of the pillar 1 with respect to the supporting body 3 and the contact surface 54 is in pressure contact with the outer peripheral surface of the pillar 1, the horizontal rod 2 is erected vertically. The horizontal rod 2 is held in a direction orthogonal to the column 1 to prevent the free end side of the horizontal rod 2 from hanging downward.

Further, as described above, when one end in the length direction is connected to one of the columns 1 and the other end is connected to the other column 1, the other end of the horizontal rod 2 is inadvertently moved upward or downward. Even if it breaks, since the contact surface 54 provided on the connecting leg 5 is pressed against the outer peripheral surface of the column 1 with a relatively wide surface in the vertical direction, the outer peripheral surface of the column 1 is connected to the connecting leg 5. There is no problem of being pressed by 5 and deformed.

In the above embodiments, the support column 1 which constitutes the scaffold
Although the present invention is applied to the connection structure of the horizontal rod 2 which is installed between the support rods 1 and the present invention, the present invention is also applied to the connection structure of the horizontal rod 2 which is installed between the support rods and the support rods which are installed between the support rods. I can.

As described above, according to the present invention, at the time of connecting the horizontal rod 2 to the support column 1, the connecting body 4 attached to one end of the horizontal rod 2 in the lengthwise direction is provided with the through hole of the support body 3. Since the one end in the length direction of the horizontal rod 1 is locked to the support body 3 by being inserted into the support rod 30, the horizontal rod 1 does not inadvertently separate from the support body 3, the horizontal rod 1 The connection work of 1 to the column can be performed safely and easily, and the abutment surface 54 is fixed by inserting the wedge 7 inserted into the through hole 30 of the support body 3 from the insertion hole 63 of the connection body 4. Since the horizontal rod 2 can be held in a direction orthogonal to the vertically-arranged support column 1 by being pressed against the outer peripheral surface of the support column 1, the free end side of the horizontal rod 2 hangs downward. Can be suppressed and the workability of assembling the other end of the horizontal rod to the other strut is improved. A.
