Abstract

(57) [Summary] [Purpose] Make it possible to easily attach the specific handrails 3 for stair frames and climbing piers to the building frame a of the frame scaffold A, and the handrails are too long for unloading and unloading. It does not interfere with the operation of the vehicle, hinders a load from falling, injuries, and prevents the handrail from projecting inward and narrowing the climbing width. Further, even when a step is generated in the assembled building frame a such as when making a scaffold on a sloping ground, the brace 4 having a certain length can be used as it is without any trouble, and the use of the reinforcing material and the handrail due to the absence of the brace is eliminated. , Eliminate the trouble and materials for that. [Structure] A pin 2 is provided so as to project from the back surface of a single clamp main body 1, and a stopper 21 that can freely project and retract is provided in the middle of the pin.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp with a bottle used for attaching stair frames of frame scaffolds, handrails, braces and the like on climbing piers.

[0002]

[Prior Art]

 Conventionally, framed scaffolds are provided with stair frames and climbing piers, but when handrails are installed beside these, single pipes for handrails are usually attached to the building frame by two free clamps. In addition, brace pins are provided on the building frame at certain positions above and below the building site, and by stabilizing the pins by applying a predetermined brace.

[0003]

[Problems to be solved by the device]

 However, if the handrail of a single pipe is attached in this way, the length of the single pipe is not specified, so it is often too long, and the protruding part unloads and interferes with unloading, and the load is hung up. There is a risk of falling and injury. The single pipe largely projects inward and the climbing width becomes narrow. Even worse, it may not be possible to lift and lower. It takes time to install and remove. In addition, since the brace has a constant length, if there is a step in the assembled building frame, such as when creating a scaffold on a sloping ground, the length becomes unsuitable and it cannot be used. In this case, generally, the brace is tied with a numbered wire. Where braces are not used, reinforcing materials and single pipe handrails are required, which requires a lot of labor and materials. The present invention is intended to solve such conventional problems.

[0004]

[Means for Solving the Problems]

 The present invention is characterized in that a pin 2 is provided so as to project from the back surface of a single clamp body 1 and a stopper 21 that can be retracted and retracted is provided in the middle of the pin.

[0005]

[Action]

 Because of the above configuration, as shown in FIGS. 2, 3, and 4, the clamp body 1 is appropriately placed in a suitable place on the building frame a that constitutes the frame scaffold A, and the pin 2 is inside (or outside). The end of the staircase frame and the handrail 3 or the brace 4 for the climbing pier of a predetermined length is fitted to the pin, and the stopper 21 prevents the pin from coming off. At this time, the existing brace 4 may be used as it is, but as for the handrail 3, as shown in FIG. 2, both ends 32 of the single pipe 31 having a constant length are flattened in the same plane, and the brace 4 is A through hole 33 to be fitted with the pin 2 is provided. In FIG. 3, b is a staircase frame.

[0006]

【Example】

 The drawings show embodiments of the invention. In the figure, 1 is a single clamp body, and 2 is a pin integrally provided on the rear surface of the clamp body. In the clamp body 1, a fixed tightening member 11 and a movable tightening member 12 are pivotally attached 13 at each one end, a base end of a bolt 14 is pivotally attached 15 to the other end of the fixed tightening member 11, and the bolt is movable. A fork portion 16 formed at the other end of 12 is detachably engaged, and the fork portion is tightened by a nut 17 screwed to a bolt. Therefore, when the building frame a is attached to the building site, the fixed tightening member 11 and the movable tightening member 12 are held together, the fork 16 is engaged with the bolt 14, and the nut 17 is tightened. The pin 2 has a rounded tip, a slit 22 is formed in the middle thereof, a stopper 21 is movably mounted in the slit, and the pin 2 is pivotally attached 23 so as to be retractable and retractable, and the inside of the slit 22 is not shown. Is provided with a spring for urging the stopper 21 in the outgoing direction. Therefore, when attaching the handrail 3 or the brace 4, it is sufficient to fit the through holes at their ends, and at that time, the stopper 21 is temporarily retracted to allow the fitting, and after passing, it is projected again. Prevent it from coming off. When removing the stopper 21, the stopper 21 may be pushed in and the end of the handrail 3 or the brace 4 may be pulled out.

[0007]

[Effect of the device]

 According to the present invention, the specific handrail 3 for the stair frame / climbing pier can be easily attached to the building frame a of the frame scaffold A, and therefore the handrail does not become too long and can be unloaded and unloaded. There is no risk of injury, risk of injury by dropping a load, no risk of injury, a large handrail protruding inward to narrow the climbing width, and a difficulty in lifting and lowering. It does not take time and effort. In addition, even when a step is created in the assembled building frame a, such as when creating a scaffold on a sloping ground, the pin 2 can be located at an arbitrary position of the building frame a, so the brace 4 having a fixed length can be used. Can be used without any problem, and the use of reinforcements and handrails due to the absence of braces can be eliminated, and the labor and materials for that can be eliminated. Moreover, the versatility is increased and repeated use is possible, which is very useful in practice.
