Description

{Assistance Scaffolding with Working Scaffold}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work footrest, and more particularly, to a work footrest having an auxiliary footrest on a footrest for work and capable of adjusting the interval or width of the footrest.

In general, the footrests for work include shipboard footboards used in ships and construction footpads used mainly in construction and civil engineering sites.

The complaints on the ship are caused when the ship's dock or various structures are constructed. In order to do such a complaint, the worker needs to work to secure a space that can be freely moved for work.

The scaffolding is installed on the brackets, which are installed at the height of the ship so that the operator can work on the inside and outside of the ship, by using clamps and fixing means using square or circular pipes.

In the safety instructions for footrest use, the flooring material, the horizontal material and the backing material should be integrated by mechanical bonding such as welding or bending, and the footing material for aluminum alloy working should be an integral structure by extrusion molding or welding or mechanical bonding The width of the work footrests shall not be less than 200mm.

In addition, when two or more flooring materials are used, the clearance between flooring materials should be 30 mm or less, and the bottom plate of the flooring should be prevented from slipping.

In case of installing the footplate, the footplate should be spaced 230mm from the wall when installing the footplate, and the pipe should be spaced 50mm away from the end of the footplate to adjust the distance from the wall to 130mm.

Accordingly, since the distance between the work foot plates for the hinged work and the foot spacing for the special paint are different, it is necessary to perform the correction work every time the foot is dried.

For example, when installing a pipe at a certain interval during a hull, it is used with annealing wire. If the footplate is modified for special painting, all the annealed wire for retention is discarded, .

There is a disadvantage that it takes a lot of work time due to such a scaffold change operation, and there is a problem that a lot of manpower and equipment are additionally required.

In addition, there are frequent problems that it is difficult to meet the delivery date (process period) in the ship drying process.

As a precedent reference, Korean Utility Model Registration Utility Registration No. 20-0346487, an auxiliary footrest of a chugging board for construction of a ship wall structure has the same symmetrical structure as shown in FIG. 1, and both side footrests 10, 10 ' A central frame 15 is provided at the center of the frame 15 and a perforated plate 17 is attached to the center of the center frame 15 and a connecting rod 18 is installed at the rear of the center frame 15 in the longitudinal direction. (20).

The assembly 20 includes a sleeve 24 that is inserted into the connection rod and moves, a first assembly 22 having one side of the sleeve and a hole 23 at the center, And a second assembly 26 which is fastened to the assembly.

A pedestal 36 is provided on the front outer edge of the footrests 10, 10 '.

However, there is an inconvenience that the auxiliary scaffold of the described prior art document can be used only when it is installed and disassembled on the scaffold for work.

In addition, since each work foot plate on which a layer is formed needs to be installed and disassembled, the working time is lengthened and work efficiency is lowered.

In addition, it is necessary to provide a footrest and an auxiliary footrest separately, and it is necessary to provide restraints on the joints necessary for fixation, resulting in poor economical efficiency.

Korean Registered Patent No. 10-1262782 (Registered on Mar. 05, 03, 2013) Korea Registered Practical Room 20-0346487 (Supplementary Scaffold of Chief Board for Ship Walls: 2004. 03. 20. Registration)

In order to overcome the above problems, the work footrest having the auxiliary footrest according to the present invention provides a correction operation through adjustment of the interval of the auxiliary footrests at every drying because the reference of the footrest spacing is different through the auxiliary footrest.

In addition, a work footrest and an auxiliary footrest are not provided separately but are provided so as to be included in a work footrest.

In addition, it provides economical efficiency through the use of a small amount of material, and enables the use of auxiliary footrests without installation or disassembly.

In order to solve the problem of the present invention, a footrest for a worker to which a worker moves is provided with a footrest for facilitating movement of the worker, an auxiliary footrest which is inserted into the inside of the footrest and protruded to one side, And a switch unit fixed to an upper end of the linking member and the linking member to allow the position to be changed.

The foot plate includes a foot plate body for allowing an operator to move the foot plate, an auxiliary foot plate groove for receiving the foot plate within the foot plate body, a switch groove capable of moving the switch portion at the upper end of the foot plate body, And a slip prevention part for preventing slippage on the top of the groove and the foot plate body.

The auxiliary footrest comprises an auxiliary footrest main body for allowing an operator to move and a protruding portion for driving the auxiliary footrest main body at the center of one side of the auxiliary footrest main body.

The connecting member has a second connecting portion which becomes a horizontal base and a first connecting portion which vertically connects the switch portion vertically to a central upper end of the second connecting portion in the shape of "ㅗ ", and the second connecting portion is fixed And a fixing groove for allowing the fixing portion to be formed.

The switch unit includes a switch body for allowing the position to be manually changed, a protrusion for reducing slippage and friction at the upper end of the switch body, and a connection member fixing groove for inserting the connection member at the lower end of the switch body .

In addition, the shape of the switch portion can be varied, and the driving section can be formed so as to be able to vary the position of the auxiliary footrest by being embedded in the switch groove of the footrest. The fixing groove of the connecting member is fixed to the upper end of the projection of the auxiliary footrest And may be composed of various fixing methods such as welding and screwing to be combined, and the switch part may also be composed of various fixing methods such as welding and screwing to fix the fitting to the first connecting part of the connecting member.

In addition, it is possible to select whether or not a slip prevention part for preventing slipping is designed according to design, and the first connection part of the connection member is connected to the groove of the connection member groove of the foot plate so that the position can be changed according to the groove do.

In addition, it is possible that the auxiliary footrests can be configured to be spaced apart from each other by a predetermined distance, A plurality of spacing adjusting grooves may be formed in the lower end or inside of the switch groove of the main body so as to fix the fixing portion.

Since the work footrest having the auxiliary footrest according to the present invention is provided with different footstep spacing standards through the auxiliary footsteps, the work footsteps having the auxiliary footsteps of the present invention are not subjected to a correction operation There is an effect that is not necessary.

In addition, since the footrest and the footrest are not separately provided, they can be used inside and can be used only when the use of the footrest is required.

Further, the economical efficiency is increased through the use of a small amount of material, the auxiliary footrest can be used without installation and disassembly, and there is an advantage that the safety accident caused by the operator's fault can be greatly reduced.
