Abstract

(57) [Summary] (with amendments) [Purpose] This invention was designed to install scaffolding sheets for work,
It is an object of the present invention to provide a scaffolding sheet locking device that is extremely easy to remove. [Structure] In this invention, a rod 2 is provided protruding from a clamp 1 that is fitted and fixed to a scaffold pipe, and a locking piece 6 is raised at the tip of the rod 2 to allow a work scaffold sheet to be attached freely. It is characterized by being fixed so that it can be folded down.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a work scaffolding sheet locking device that makes it extremely easy to attach and remove the work scaffolding sheet.

0002

[Conventional technology]

As is well known, scaffolding has been used in the construction of buildings, and scaffolding sheets are suspended from the scaffolding for purposes such as rain protection. Conventionally, a scaffolding sheet has been attached to this scaffolding by tying together a number of eyelets attached to the scaffolding sheet and a scaffolding pipe with strings.

[0003]However, tying and removing the string in this way is a very troublesome task, and this poses a problem in that the work efficiency is not improved. Not only that, but
Since the string falls to the ground after use, it is necessary to clean and dispose of the string, which is not only time-consuming but also undesirable from the point of view of resource conservation.

[Problem that the idea aims to solve]

This idea aims to solve these problems all at once.
To provide a scaffolding sheet locking device which greatly facilitates installation and removal of a scaffolding sheet and does not generate waste materials such as strings.

[0005]

[Means to solve the problem]

The configuration of the present invention in accordance with the above object includes a fitting fitting having a fixing bolt pivotally attached to one end thereof, and a clamping fitting pivotally attached to the other end of the fitting fitting, and a notch at the tip of the clamping fitting. A clamp that is fitted and fixed to a scaffolding pipe to which the fixing bolt is locked and the clamping fitting can be freely tightened to the fitting fitting side by the fixing bolt, a rod that protrudes from the clamp, and a tip of the rod. It is characterized by having a locking piece that allows a work scaffolding sheet fixed to be raised and lowered to be freely attached.

【Example】

Next, embodiments of the present invention will be described based on the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, in which a rod 2 is protruded from a clamp 1 that is fitted and fixed to a scaffolding pipe, and a two-split cut 3 is formed at the tip of the rod. A locking piece 6 is loosely fitted into a pin 5 placed horizontally in the notch 3 through an elongated hole 4 formed in the center thereof. By sliding the locking piece 6 in one direction and folding it down, it forms a straight line with the rod 2, as shown by the broken line in the figure, and by folding it, it stands perpendicular to the rod 2, as shown by the solid line in the figure. It is configured as follows. A rounded taper 7 is formed at one end of the locking piece 6, and this surface abuts and locks on the bottom surface of the cut, so that the locking piece 6 becomes linear. When the locking piece 6 is tilted in the opposite direction (to the right in FIG. 1), the other end 15 of the locking piece 6 comes into contact with the rod 2, so the locking piece 6 does not become straight. The clamp 1 is constructed by pivoting a fixing bolt 11 to a shaft 10 installed horizontally at one end of the fitting 9, and pivoting a clamping fitting 13 to a shaft 12 installed horizontally at the other end of the fitting 9. has been done.

[0007]

[Effect]

Next, the operation of the present invention configured as described above will be explained. First, a predetermined number of locking devices of the present invention shown in FIG. 1 are fixed at predetermined intervals at predetermined positions on a scaffold pipe facing the scaffold sheet. For fixing, open the clamping metal fitting 13 of the clamp 1, bring the fitting fitting 9 into contact with the pipe, and insert the fixing bolt 11 into the notch of the clamping metal fitting 13.
Just fit them together and tighten them with the nuts 14. Then, the locking piece 6 of the rod is brought into a straight line with the rod 2. In this state, the end 7 of the locking piece is locked to the bottom surface of the notch 3 of the rod, so the locking piece remains stationary in a straight line. Then, after fitting the eyelet of the scaffolding sheet onto the rod 2, as shown in FIG. 1, when the tip of the locking piece 6 is erected upward, the locking piece 6 becomes in the solid line state in FIG. .
In this state, even if a force is applied to the locking piece 6 from a direction parallel to the right side of the rod 2 in FIG. 1, the locking piece 6 will not be in a straight line state. Therefore, the eyelet of the scaffolding sheet is effectively prevented from coming off from the rod 2. To remove the scaffolding sheet, lift the locking piece 6 upward in FIG. When the locking piece 6 is folded down, the rod 2 and the locking piece 6 stop in a straight line, so the scaffolding sheet can be easily pulled out from the rod 2 as it is. In order to fix the locking piece to the tip of the rod so that it can be raised and lowered, the method is not limited to the above embodiment. It is fixed so that it can appear and retract freely within the pipe,
Usually it protrudes from the pipe, but when installing the scaffolding sheet, it may be constructed so that it can be pushed into the pipe against the force of the spring.

[0008]

【effect】

As described above, according to the present invention, the scaffolding sheet can be easily attached and detached with one touch using the locking piece fixed to the tip of the clamp, which dramatically improves the efficiency of attaching and removing the scaffolding sheet. In addition, since there is no need to use strings like in the past, there is no need to clean up the strings scattered on the ground, and this also meets the need for resource conservation.
