Description

Construct tool for working scaffold}

The present invention relates to a tool for constructing an aerial platform, and more specifically, for maintenance, repair work at a high height such as a wall of a ship dock (cargo hold or various seawater tanks) or work at a high place of a general building. The present invention relates to the provision of a tool for constructing an aerial platform that facilitates installation of a bench for securing space.

The aerial work occurs during the construction of a ship's dock or various buildings and constructions, and for the aerial work, a work platform for securing a space in which an operator can freely move for work is required.

Construction of aerial work platform to which the prior art is applied,

First, when looking at the workbench for maintenance and repair in the dock of a considerable height inside the ship, a constant height (work) on the roughly "a" shaped reinforcement frame installed at regular intervals in the vertical direction for strength reinforcement inside the hull shell of the ship. Position) to weld the angle.

The plate member is fixed to the upper surface of the welded angle so that the operator can walk, and the workbench is installed by fixing a vertical bar for connecting the rope to the outer end of the angle.

The worker is located on the workbench installed as described above to perform the maintenance and repair of the inside of the hull shell of the dock, and when the work is completed as high as the worker can work on the workbench, dismantle the installed workbench to the next height. By repeating the installation of the workbench in the same manner as before, the wall surface of the dock is maintained and repaired.

In the case of working in the above manner, it takes a considerable time to weld the angle, as well as having to repeat this for each working height has the disadvantage that it takes more time and manpower to install the workbench than the actual work.

In particular, when the welded angle is removed to be installed at the next height, the angle is removed by oxygen cutting, and the grinder must be ground again so that the weld mark does not appear.

In the case of general buildings and constructions, most of them are constructed with H beams without using reinforced concrete as the base of the constructions and constructions.

As described above, the installation of a workbench or safety net as a scaffolding has a disadvantage in that the higher the height to be constructed, the more the risk is doubled because the scaffold is continuously installed on the ground without connecting the scaffold in the H beam.

Even when the scaffold is connected in the H beam, the work for the initial connection is quite dangerous, and since the worker performs the scaffolding installation outside the building, there is a high risk of a safety accident such as a fall before the work bench or safety net is installed. Various problems are occurring.

Therefore, the present invention is designed to solve the above problems, as well as to facilitate the construction (installation) of the workbench on the dock provided in the ship, as well as to easily build a safe platform in the construction and construction of the aerial platform To enable work;

The purpose is to reduce the time and cost of installing a workbench, as well as to facilitate disassembly, thereby reducing air shortening and construction costs, and contributing to the convenience and safety of users.

Aerial work platform construction tool 30 to which the technology of the present invention is applied;

Fixed to the H-shaped reinforcement frame 34 which is installed at equal intervals in the vertical direction for strength reinforcement on the dock 33 of the ship 31, or the wall 33 of the ship 31 or H beam 35 used in the construction of general buildings and structures. It is composed of a bridge 42 for installing a clamp 40 and the work space 41 which is integrally connected to the rear of the clamp 40 to the operator can work.

The clamp 40 has a roughly c-shaped clamp body 46 formed with an insertion groove 45 to accommodate the thickness T of the reinforcement frame 34 or the H beam 35. The clamp body 46 is provided in front of the clamp 40, the reinforcing frame 34 and the fastening hole 47 for firm binding with the H beam (35).

The fastener 47 is a handle to facilitate tightening and releasing of the fastening bolt 49 and the fastening bolt 49 is screwed to the screw hole 48 to form the front center of the clamp body 46 To have a head 51 having a further (50).

The tightening bolt 49 is configured to continuously maintain the tightened state by the locking bolt 53 is coupled to the upper surface of the thick portion 52 formed on the outer side of the screw hole (48).

The bridge 42 has a bridge bar 55 protruding to a long length to the rear of the clamp body 46, the upper end of the bridge bar 55 to connect the guard rope (56) And a guide hole 59 into which the guard bar 58 having the rope hanger 57 can be inserted at an intermediate position.

The slot 60 is formed at the rear of the guide hole 59 so that the locking piece 61 formed to prevent the separation from the lower side of the guard bar 58 may enter.

Aerial work platform construction tool 30 of the present invention as described above;

The clamp 40 of the tool 30 is fixed to the reinforcement frame 34 or the H beam 35 at the position to be operated while maintaining the same height at the same height, and protrudes to the rear of the clamp 40. The upper surface of the bridge 42, the base plate 70 for securing the work space 41 is placed, and the guard bar 58 connecting the guard rope 56 is inserted into the end of the bridge 42 is not separated It is done.

Looking at the process of fixing the clamp 40 to the reinforcing frame 34 or the H beam 35, the clamp bolt (49) of the tightening hole 47 provided in front of the clamp body 46 is retracted to clamp ( The thickness T of the reinforcement frame 34 or the H beam 35 enters the insertion groove 45 of the 40.

As described above, when the reinforcing frame 34 or the H beam 35 is inserted into the insertion groove 45, the clamping bolt 49 of the tightening hole 47 screwed to the front of the clamp body 46 is tightened to clamp the clamp 40. ) Is completed in a solid state with the reinforcement frame 34 or the H beam 35.

Of course, when the clamp 40 is completed using the fastener 47 in a rigid state with the reinforcement frame 34 or the H beam 35, the fastener 47 may be fastened to prevent loosening. Tighten the locking bolt 53 further provided in the thick portion 52 formed on the outer side of the screw hole 48 for coupling the sphere 47 so that the insertion hole 47 is not released.

After fixing the clamp 40 at the same height as above, the bridge 42 formed integrally with the clamp 40 is placed and fixed on the plate base 70 so that the worker can move freely. The guard bar 58 is inserted into the guide hole 59 formed at the end of the bridge bar 55 constituting the bridge 42.

When the guard bar 58 is inserted, the locking piece 61 fixed to the lower end of the guard bar 58 is inserted in the slot 60 direction formed in the guide hole 59 and then inserted. This is completed and the inserted guard bar 58 is not released by rotating the guard bar 58 so that the engaging piece 61 is in the opposite direction to the slot 60.

By connecting the guard rope 56 to the rope hanger 57 provided at the upper and middle positions of the guard bar 58 in the above state it is possible to prevent the fear of falling during operation.

The work platform is installed using the aerial work platform building tool 30 at the position (height) to work as described above, and when the work is completed, the work may be installed by releasing it and installing it again at the height.

It is easy to install and dismantle the aerial platform by using the aerial platform construction tool 30 as described above, and does not need to use a separate tool such as a welding machine during installation and dismantling work, and in particular, does not require a post-disassembly post-process. Has

The present invention as described above allows the construction of aerial platform easily as well as the docks of ships to enable safe work performance, in particular, such as structures such as oil or gas carriers, onshore oil and gas tanks By making it easy to apply to ships or structures that cannot be welded due to the risk of fire and explosion, it is possible to reduce the time and cost of installing the workbench, as well as to dismantle it. It is designed to have many expected effects such as it can contribute to improved safety.
