Are pivotally connected to each other so as to pivotally connect the sides on which the fitting portions 3 are formed.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a scaffold pipe joint for connecting scaffold pipes used for scaffolding work and temporary handrail construction.

[0002]

[Prior art]

 At the corners of scaffolding work and temporary railing work, cross the ends of two straight pipe scaffold pipes with the standing pillar pipe, and clamp the two scaffold pipes at the intersection. And two scaffold pipes at the intersection and the support pipe are fixed by fixing means such as a binding wire or a fixing clamp.

However, in the conventional connecting means, each end of the two crossed scaffold pipes unnecessarily protrudes, which is dangerous in work and impairs aesthetic appearance.

[0004]

[Problems to be solved by the invention]

 The present invention intends to provide a joint for a scaffold pipe in which a connecting angle of a connecting portion of two scaffold pipes to be connected can be freely adjusted mainly at a corner portion of a scaffolding work or a temporary handrail construction. is there.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the scaffold pipe joint of the present invention is provided with a joint base and tubular fitting portions for detachably fitting and fixing a tubular scaffold pipe at both ends of the joint base. A joint for a scaffolding pipe, wherein the joint base is constituted by a pair of joint members having a base portion provided with the fitting portion and a joint arm portion, and the joint arm portions are crossed with each other. A through-hole is formed in the through-hole, and a pair of joint members are connected by a connecting pin inserted and mounted in the through-hole so that the fitting portion forming sides can be pivotally connected to each other with the connecting pin as a pivot. Features.

The two scaffold pipes respectively fitted to the tubular fitting portions are configured by connecting a pair of joining members so that the fitting portion forming sides can be pivotally connected to each other with the connection pins as pivots. With the joint base described above, the connection angle can be freely adjusted in accordance with the corner angle of the corner portion of the scaffolding construction or temporary handrail construction used.

[0007]

[Embodiment of the invention]

 An embodiment of a joint for a scaffold pipe of the present invention will be described with reference to the drawings. 1 is a perspective view of the scaffold pipe joint of the present invention, FIG. 2 is a longitudinal sectional side view of the scaffold pipe joint shown in FIG. 1, and FIG. 3 is a scaffold pipe joint of another embodiment of the present invention. The perspective views are shown respectively.

In the drawings, reference numeral 1 denotes a scaffold pipe joint. The scaffold pipe joint 1 removably fits and fixes a joint base 2 and a tubular scaffold pipe 10 to both ends of the joint base 2. It is constituted by projecting tubular fitting portions 3 and 3 respectively. An L-shaped groove 4 is formed at the pipe end of the fitting portions 3, 3, and a locking projection 11 provided inside the end surface of the tubular scaffold pipe 10 is formed in the L-shaped groove 4. The scaffold pipe 10 is inserted from the outside of the fitting portion 3 while being matched, and the two are connected by twisting them at a position where the locking projection 11 contacts the corner of the L-shaped groove 4. You.

The joint base 2 is constituted by a pair of joint members 5, 5 having a base 6 having the fitting portion 3 protruding therefrom and a joint arm 7, wherein the joint arms 7, 7 intersect each other. A through-hole 8 is formed at the intersection, and a pair of joint members 5 and 5 are pivotally connected to the pair of joint members 5 and 5 with the connecting pin 9 as a pivot axis by connecting pins 9 inserted and mounted in the through-hole 8. It is configured to be movably connected.

The joint arms 7, 7 of the joint members 5, 5 may have a configuration in which the opposing surfaces of the arms 7, 7 intersect each other as shown in FIG. 1, or as shown in FIG. As described above, one joint arm portion 7 may be formed in a forked shape, and the other joint arm portion 7 may be inserted and crossed in the forked arm portion 7.

With the joint for scaffolding pipes configured as described above, as shown in FIG. 2, the two scaffolding pipes 10 and 10 fitted to the tubular fitting portions 3 and 3, respectively, form a pair. The joint base 2, which is formed by connecting the joint members 5 and 5 with the connecting pin 9 as a pivot and the side on which the fitting portion 3 is formed so as to be able to pivot with each other, is used for scaffolding work or temporary installation using the connection angle. It can be adjusted freely according to the corner angle of the corner part of the handrail construction.

It is preferable that the corners indicated by reference numeral F in FIGS. 1 and 3 be chamfered to have a rounded shape.

[0013]

[Effect of the invention]

 According to the joint for scaffolding pipes of the present invention, the connecting angle of the connecting portion of the two scaffolding pipes to be connected can be freely adjusted mainly at the corners of the scaffolding work and the temporary handrail construction. The scaffold pipe has an excellent effect that the end of the scaffold pipe does not protrude, is safe in operation, does not impair the appearance, and can be easily connected.
