Figure 2 is a schematic diagram showing the main part of the device according to the invention
3 to 5 are diagrams showing a state in which a scaffold is constructed by an apparatus according to the present invention

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

One aspect of the present invention proposes an apparatus for continuously installing scaffolding scaffolds using H beams of offshore plant decks. 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.

On the other hand, in FIG. 1, reference numerals SF denote the positions of the footrests 25 to be 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, there is provided a pole 31 on one side of which is detachably fixed to the H beam. Although it is preferred to use a tubular member such as a steel pipe as the pole 31, it may partially include a bar member.

Further, according to the present invention, one side of the rail 32 supporting the footrest is rotatably connected to the other side of the pole. It is preferable that the rails 32 use the same tubular member as the steel barrel 31 as the pole bar 31.

The pole piece 31 and the rail 32 constitute an integral coupling support body 30 with the hinge 33 interposed therebetween. The hinge 33 rotatably connects the pole 31 and the lower end of the rail 32. Therefore, the supporting support body 30 of the pole 31 and the rail 32 can be quickly opened when used for folding or scaffolding in storage or transportation.

According to the present invention, the supporting member connects one side of the pole 31 and the other side of the rail 32 so that the pole 31 and the rail 32 do not extend beyond a predetermined angle.

As a detailed configuration of the present invention, the support is characterized by having a wire 35 connecting the pole 31 and the rail 32 so as to maintain a right angle. The wire 35 is connected to the pole 31 and the rail 32 on the opposite side of the hinge 33, respectively. When the pole 31 and the rail 32 are expanded in the construction process, the wire 35 is held in a state of FIG. 2 while being strained. It is preferable that the portion where the wire 35 is connected to the rail 32 is installed so as to protrude somewhat using a support pin (not shown) or the like so as to avoid interference with the end portion of the foot plate 25. [ A ring (not shown) is attached to the end of the support pin to facilitate detachment and attachment of the wire 35.

At this time, since the joint supporting body 30 of the present invention is constructed so as to be opposed to the left and right sides, it is preferable to protrude the support pins to both sides for sharing the left and right sides as described later. More preferably, the support pin slides on the rail 32 and protrudes to a desired side surface.

As a detailed construction of the present invention, a balustrade 50 is provided to increase the coupling force between the adjacent pole pieces 31. [ In FIG. 2, for the sake of simplicity of the configuration, the railing 50 is illustrated as a rectangle, but it may be configured as a ladder or a truss. In any case, the handrail 50 is coupled between the adjacent poles 31 to enhance the structural stability of the string receiving scaffold while preventing workers from falling.

The pole 31 has a beam clamp 42 fixed to the top of the pole 31 to grasp the H beam 15 and a beam clamp 42 fixed to the top of the pole 31 to hold the handrail 50. [ And further includes a U-shaped clamp 48 fixed thereto. It is preferable to provide the fixing means 40 to increase the structural rigidity while connecting the coupling supports 30 adjacent to each other. The fixing means 40 includes a structure for connecting the pole 31 to the H beam 15 on one side while continuously connecting the pole 31 on the other side. The beam clamp 42 uses a structure that grasps the flange of the H beam 15 to one side or both sides. The U-shaped clamp 48 is provided with a groove for gripping the handrail 50 based on a U-shaped cross section which is in close contact with the outer circumferential surface of the pole 31. Although the bolt is exemplified by the clamping member of the beam clamp 42 and the U-shaped clamp 48, it does not exclude other methods including cicada rings. Thus, the fixing means 40 implements the construction as shown in FIGS. 3 to 5 to support a plurality of foot plates 25 in a suspended state.

As a modification of the present invention, the U-shaped clamp 48 is provided so as to be positionally displaceable on the outer peripheral surface of the pole base 31 via a pivot 46. As described above, since the left and right poles 31 of FIG. 2 are configured in common, the position where the U-shaped clamp 48 engages with the handrail 50 can be varied. The pivot 46 is provided on the outer periphery of the pole 31 so as to be rotatable 360 degrees. For example, in FIG. 2, the pivot stand 46 is exposed in the pole section 31, but it may also be provided with a stepped groove in the pole section 31 to accommodate the pivot stand 46. In any case, when the rail 32 is folded toward the pole 31 side, the position of the U-shaped clamp 48 can be changed by the pivot 46, and then the binding can be performed.

As a detailed configuration of the present invention, the rail (32) is characterized by having a fitting base (44) engageable with a male and female structure and being positionally fixed. 2, a groove is formed at one end of the rail 32 to engage with and engage with a plate-like projection at the other end. A through hole for fastening a pin or a bolt is formed on the fitting base 44 formed by the protrusion and the groove. In the drawing, the fitting base 44 may be formed as a circular projection having a diameter slightly smaller than the inner diameter of the rail 32. [ In this case, the end of the rail 32 engaged with the circular protrusion can be used as it is without forming a separate groove. In any case, the fitting base 44 enhances the structural stability of the coupling support 30 connected by a triangular structure.

According to another aspect of the present invention, there is provided a method for continuously installing scaffolding scaffolds based on the configuration of claim 1, comprising the steps of: engaging a pole (31) with an H beam in a coupling support (30) An initial installation step of unfolding the foot plate 25 and mounting the foot plate 25; And repeating the operation of installing the pole 31 and the rail 32 in the same manner in the second and subsequent rows of the coupling support 30 and mounting the pedal 25 in the same manner . The initial mounting step constituting the first supporting row 30 of the first row utilizes the above-described footing module 20, but the repetitive mounting step continues the work in the same pattern utilizing the completed bonding support 30 immediately before.

As an example of the construction, the pole base 31 is engaged with the H beam 15, the rail 32 is extended and the foot plate 25 is laid as shown in FIG. 3, and the second row of the coupling supports 30 And then connected to each other using the mutual sandwiching bracket 44, and the third supporting unit 30 is unfolded as shown in FIG. 5, and the installation is continued in the same manner. Of course, the railing 50 is provided by the U-shaped clamp 48 in the course of the installation of the coupling support 30. [

On the other hand, the pole 31 of the present invention has a structure for reducing material / management cost by sharing the right and left sides. The connecting structure of the wire 35 and the engaging structure of the fittable member 44 do not cause mechanical restraint because the rails 32 must be rotated in opposite directions with respect to the pole 31. [

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.
