Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a device for constructing a scaffold suspended by a pole (30) and a rail (32) on an H beam (15) of a deck. FIG. 1 illustrates a state where a multi-layered deck (DK) is provided in a marine plant composed of three stages of production modules (MD). In the method of the present invention, the conventional external scaffold 11 and internal scaffold 12 are reduced or eliminated. Utilizes but is not necessarily limited to a number of H beams 15 included in the deck. The hanging scaffold includes a pole 30, a rail 32, and a foot plate 34 in a suspended state below the vertically arranged H beams 15. Reference numeral 36 denotes a clamp used to connect the pole 30 and the rail 32 to each other.

In FIG. 1, reference numerals SF denote the positions of the footrests for design applied to the scaffold of the present invention.

According to the present invention, a scaffolding module 20, which is formed in a multi-layer structure to reduce or replace the external scaffold 11, is installed adjacent to the side surface of the deck to assist movement of personnel and materials. The scaffolding module 20 may include a fixture bound to a deck or the like of an offshore structure, and a ladder for lifting and lowering the operator.

According to the present invention, the suspending means 40 contacts the H beam 15 at the upper end of the main body 41 via the traveling wheel 42 and has a beam clamp 45 which can be engaged with the rail 32 at the lower end . The suspending means 40 is formed in a shape similar to the pole 30 and temporarily used in the process of installing the pole 30. [ The main body 41 of the suspending means 40 has a structure in which a housing is integrally fixed to the upper end of a steel pipe or a steel bar. The traveling wheels 42 are mounted on the upper surface of the main body 41 so as to contact the flanges of the H beams 15 on both sides. 3 illustrates driving the one-side traveling wheel 42 and the other-side traveling wheel 42 in an idle state. The beam clamp 45 closely grips an object, such as the rail 32, in a finger manner. The rail 32 is formed of a steel pipe and a plate material in a ladder structure, and is horizontally suspended using a pole 30. The fingers of the beam clamp 45 are formed to grip the steel pipe portion of the rail 32.

According to the present invention, the control means (50) is mounted to control the movement of the main body (41) on the H beam (15). The control means (50) mounts the main body (41) of the suspending means (40) as a main function to move the H beam (15) to a desired position. The movement of the main body 41 is instructed by a wireless remote control (not shown) carried by the operator.

As a detailed configuration of the present invention, the beam clamp 45 of the suspending means 40 is characterized in that a structure for performing clamping / unclipping by an external force applied to the lever is applied. The beam clamp 45 can be applied as it is or after being modified. In either case, actuating the lever which is exposed to the outside of the beam clamp 45 is based on the principle of causing the finger to open and close by a mechanical link. The control means 50 can additionally mount the clamping / unclamping function of the beam clamp 45. [

3, the first embodiment of the present invention operates the beam clamp 45 manually. Since the upper and lower ends of the hypothetical means 40 are not linked to each other, the main body 41 can use a steel bar as well as a steel pipe . Fig. 3 illustrates manual operation by bolts, but other schemes such as cicada rings are also possible. An example of the construction using the manual beam clamp 45 is described with reference to an example of construction by the electric beam clamp 45 of FIG. 4 to be described later.

In the detailed construction of the present invention, the above-mentioned suspending means 40 is formed in a structure that can be opened and closed via at least one side of the main body 41 with a hinge clamp 48 interposed therebetween. 3 illustrates a state in which a portion of the main body 41 where the right traveling wheel 42 is in an idle state is formed in a hinge structure and a hinge clamp 48 is added. The hinge clamp 48 is unlocked immediately before the mounting means 40 is installed on the H beam 15 and the hinge clamp 48 is kept in the locked state while traveling on the H beam 15. [

The control means 50 includes a control portion 51 on which a microcomputer circuit is mounted, a traveling portion 53 for applying a forward and reverse rotational force of the traveling wheel 42, a power source And a power supply unit 55 for providing a power supply voltage. The control unit 51 includes a microprocessor, a memory, and a microcomputer circuit having an input / output interface. The traveling section 53 is constructed on the basis of a servo motor or a deceleration motor and applies power to the traveling wheel 42 via the electric motor 43. [ The electric motor 43 can be selected from a belt system, a gear train system, and the like. The power supply unit 55 includes a rechargeable battery and supplies power to the control unit 51, the driving unit 53, and the like. In addition, a module for communicating with the remote controller of the user is mounted on the control unit 51.

As a second embodiment of the present invention, the control means 50 further comprises an actuating portion 57 for applying a rotational force to an actuating shaft 47 connected to a lever of the beam clamp 45 . Referring to FIG. 4, the second embodiment of the present invention operates the beam clamp 45 electrically, so that the upper and lower ends of the hypothetical means 40 are linked to each other by the operation shaft 47, It is good to do. The operating portion 57 is simple in construction using a stepping motor, but does not exclude the solenoid. The operation shaft 47 is connected to the operation part 57 at the upper end and to the lever of the beam clamp 45 at the lower end. The control unit 51 mounts an algorithm for driving the traveling unit 53 and the operating unit 57 in the memory.

As an example of the construction, the pole 30 of the first row is disposed below the H beam 15 in the region closest to the footing module 20, and the traveling wheel 42 of the hiding means 40 is connected to the H beam 15 And then moved to an appropriate position. In this process, one end of the rail 32 can be horizontally transported to the beam clamp 45. Thereafter the rail 32 is joined to the pole 30 of the first row by means of the clamp 36 and the foot plate 34 is pushed sequentially onto the rail 32, The pole column 30 of the second row is coupled and the beam clamp 45 of the suspending means 40 is unclamped to move to the next position and the installation of the footstep 34 is continued while repeating the above process.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
