LT 6253 B

TECHNICAL FIELD The present invention relates to suspended scaffolding which is used as a scaffold when installing equipment or equipment in a small room with concrete walls, as well as in connection with the installation method using such scaffolding. The state of the art of the invention

In a building such as a nuclear power plant, equipment, pipelines, ducts (ducts) and cable trays are installed in small spaces with concrete walls.

The construction of such buildings has traditionally been used for subsequent installation. In the subsequent installation, the floor and walls are first formed, and then scaffolding is built. Ceiling scaffolding on the ceiling, using a ceiling construction, installs a hoist or similar device and performs wall finishing work. Then remove the scaffolding and paint the floor. Then, through the wall in the access opening, equipment or equipment, pipelines, support elements and other things to be installed in a small room. Finally, after rebuilding and after removing the scaffolding for installation work, equipment or equipment, pipelines, ducts, etc. are installed.

Using such a retrofitting method extends the construction period, and high-level work places a lot of work on re-assembling scaffolding. Therefore, a pre-installation method has been implemented where some equipment or equipment is temporarily pre-assembled.

The modular design described in JP2012-207430A provides a component for hanging devices or equipment to be placed in a small room, where the length of the suspension means is adjusted to the position of the arrangement, depending on the layout of the small room. This component of equipment or equipment can be raised from the floor surface so that the floor surface can be easily painted. The essence of the invention

While using modular design as described in JP2012-207430A, it is possible to paint the floor surface by lifting components of equipment or equipment, but this modular design makes it difficult to pre-assemble equipment or equipment using the hanging means 2 accordingly.

LT 6253 for the layout of Room B. In addition, the modular design with a large number of temporarily assembled equipment or equipment is difficult and therefore difficult to control as it requires a large crane or the like.

During such installation work, it is desirable to place the suspended scaffolding throughout the room so that it can be used as an installation scaffold, while ensuring that the floor surface is accessible and that equipment or equipment can be loaded into the room.

However, foreign construction sites are mainly used for assembling scaffolding, the frame and flooring of which are assembled from the floor surface, and the number of skilled workers capable of professionally installing suspended scaffolding across the room at high altitude is limited. Therefore, construction work carried out abroad is characterized by an excessive number of scaffolds, and in many cases does not ensure the availability of floor surface, which hinders the installation of equipment or equipment. The present invention has been designed to address the above-mentioned problems encountered in conventional technology, the object of the present invention is to provide suspended scaffolds that facilitate the installation of equipment or equipment in a small room and which eliminates the need for re-dismantling and rebuilding scaffolding; also offer a mounting method using these hanging scaffolding.

As a primary means of achieving this goal, the present invention provides a suspended scaffold comprising: a frame formed by temporarily assembling the pillars and supports, where the frame can be loaded from a small room with floor surfaces and wall surfaces, the sides of the ceiling, and the pillars can be arranged in such a way in positions where almost overlaps with ceiling beams, looking from the top of the small room, and then partially removed, after the ceiling is finished; scaffold supports that can be fixed to the pillars, where each scaffold support can be attached to the ceiling beams and the position of the scaffold support can be adjusted horizontally in relation to the ceiling beam; and installation scaffolding for installation work on equipment or equipment, where the installation scaffold can be attached to a frame at a height that allows the installation of equipment or equipment on the floor of a small room 3

EN 6253 at B level.

As a second means of achieving the above-mentioned object, the present invention provides that each of the scaffold supports in the above-mentioned first-aid hanging scaffold has a first cylindrical body and a second cylindrical body disposed at the center of the axis of the first cylindrical body and engages with a shaft capable of rotating about its axis, and wherein the second cylindrical body may extend / shrink in the axial direction from / to the first cylindrical body.

As a third tool for achieving the stated purpose, it is proposed that the present invention, as a first and second means of hanging scaffold, additionally include ceiling scaffolds attached to a frame which are loaded with this frame from the ceiling side and removed after completion of the ceiling and scaffold wall finishing. for work, attached to a frame that is loaded with this frame from the ceiling side and is removed after finishing the small room walls.

In order to achieve the purpose of the fourth method, the present invention provides a mounting method using suspended scaffolding comprising: a structure in which the scaffolds, scaffolding, scaffolding, and scaffolds, which are separated temporarily in the frame, are placed in a small room in which floor surfaces and wall surfaces are formed; forming a ceiling of a small room using scaffolding for building a ceiling; scaffold supports that can be fixed to the ceiling beams when the ceiling is formed, where the mounting position of each scaffold support is adjustable horizontally or vertically in relation to the ceiling beam, joins with frame struts and finishes the wall finish using scaffolding for wall finishing work; removes ceiling scaffolding, scaffolding for wall finishing work and some of the supports, and installs hanging scaffolds where mounting scaffolds are hung on the ceiling beams; and loads equipment or equipment into a small room and installs equipment or equipment using scaffolding.

According to the principles described above, hanging scaffolds are mounted at a height of the frame at which equipment or equipment can be loaded 4

EN 6253 B Works. This ensures that the floor surface is accessible, and equipment or equipment can be easily loaded into a small room. Further, equipment or equipment may be temporarily installed or installed using suspended scaffolding as a basic scaffold, and therefore no longer needs to be re-dismantled and erected as a conventional technology. In addition, the frame posts that are pre-arranged in positions that almost overlap the ceiling beams, viewed from the top of the small room, can be easily hung on the ceiling beams using scaffold supports that are adjustable horizontally. It is possible to attach hanging scaffolds.

Scaffold supports and frame according to the principles described above can be easily aligned in the vertical direction by removing gaps up and down.

Taking into account the principles described above, as ceiling scaffolding and wall scaffolding are already pre-installed in the frame, loading the suspended scaffolding into a small room eliminates the need to construct any other scaffolding ceiling for construction and wall finishing work, and may reduce the workload.

In accordance with the principles described above, since access to the floor surface can be ensured, no complex operations are required when the components of the equipment or equipment have to be pre-assembled by means of hanging devices, such as hanging on ropes, before loading them into the room, as traditional technologies in modular In the structure of the floor can not be ensured accessibility.

In addition, depending on the working process, these scaffolding 30 can be used to temporarily assemble new scaffolds needed for installation work.

Scaffold supports 40

As shown in FIG. 3-5, each scaffold support 40 has a base structure comprising connecting means 42, a first cylindrical body 45 and a second cylindrical body 53.

The connecting means 42 are formed by a pair of connecting parts, the upper part of which has tightening elements 43 that hold both ceiling beams 18 (H-shaped, steel) 7

The pipe 41 is arranged so that its axis is directed perpendicular to the longitudinal direction of the ceiling beams 18, and is set to be slightly longer than that of the flange 19 of the flange 19 of the floor surface. beyond the length of flange 19. In one embodiment of the fastening elements 43 of the present invention, C-clamps are used to compress the ends of the flange 19. These clamping elements 43 may be secured by screwing them in the flange 19 of the flange 19 in the thickness direction from the ceiling side after the ends of the flange 19 are inserted into the notches of the clamping elements 43. Also, in one embodiment of the clamps 44 of the present invention, pipe clips having an internal diameter of approximately the same diameter as the pipe 41 are used. Each clamp 44 can be fastened to the pipe 41 by inserting a pair of semicircular elements which are foldably connected at one end to the rotation capability along the radial direction 41 of the tube, and then to the other ends by screwing the attachment screw 441. The connecting means 42, the structure of which is described above, are provided in advance. a fixed length pipe 41 is fastened to the coupling pairs 44 of the coupling means, and then the flange 19 of the ceiling beam 18 is compressed by tightening elements 43.

One end (upper) of the first cylindrical body 45 has a flange 46 and a clamp 47 on this flange 46. The clamp 47 is a pipe clamp that holds the tube firmly 41. The clamp 47 may be attached to the tube 41 by inserting a pair of semicircular elements at one end fittingly connected to the rotation capability along the radial direction of the tube 41 and then tightening the other ends with the fastening screw 471. The first shaft 48 (see Fig. 5) is provided inside the first cylindrical body 45. The axial center 48 of the first shaft is disposed centrally with respect to the axial center of the first cylindrical body 45. The head 49 of the first shaft 48 is based on allowing the head to rotate the bearing bearing, which comprises the bearing balls 451 and the bearing receiver 452 contained within the first cylindrical body 45. The outer edge of the head 49 forms an angular gear. On the surface of the first portion 48 of the first shaft are outer threads 50 which protrude at the other end (lower) of the first shaft 48 on the opposite side of the head 49. The second shaft 51 is arranged in such a manner that the opening 45a on the outer surface of the first cylindrical body 45 extends in such a direction that its axial center is perpendicular to the axial center 48 of the first shaft. The outer edge of the second shaft 51 of the second shaft 51 also comprises an angular gear, similar to the head 48 of the first shaft 49. The first shaft 48 and the second shaft 8

The second cylindrical body 53 is smaller in diameter than the first cylindrical body 45 and can be inserted into the first cylindrical body 45. Inside one (upper) end of the second cylindrical body 53, inner threads 54 are engaged which engage the outer thread 50. The second cylindrical body 53 at the other end of the inner wall is an annular ball bearing consisting of bearing balls 531 and a bearing receiver 532. The flange portion 55 includes a flange inner cylinder 56 which can be inserted into a second cylindrical body 53. The inner cylinder 56 of the flange has a ring at the distal end 56; this cylinder rests on the ball bearing so that it can rotate around its axis. The flange portion 55 is of the same shape as the flange 23 on the upper end of the strut 22 and the flange portion 55 and flange 23 may be connected to the fastening screw 551.

The pair of clamps 44 of the coupling means 42 and the clamp 47 of the first cylindrical body 45 of the coupling support 40, the structure of which is described above, are pre-attached to the pipe 41. Then, the coupling means 42 of the coupling means 42 are temporarily secured to both ends of the beam flange 19. the flange portion 55 of the second cylindrical body 53 is fastened to the flange 23 of the pillar 22 by a fastening screw 551. Then, with a tool, such as an impact wrench, a second shaft 51 is rotated to move the second cylindrical body up or down. In this way, the frame 20 can be connected and attached to the ceiling beams 18.

Ceiling scaffolding 60

Ceiling scaffolding is a scaffolding used in the construction of ceiling 16. They are installed at the highest level 11 of the structure. Ceiling scaffold 60 is formed by placing separate (disassembled) scaffold boards across the plane of the frame 20, looking from the top of the small room.

Scaffolding for wall finishing 70

Wall scaffolding 70 is a scaffolding used for finishing work on wall surfaces 14. In construction 11, they are installed on a low-floor level than scaffolding scaffolding 60. Scaffolding 70 for wall finishing works must be 9

LT 6253 B is formed on four sides of four wall surfaces, viewed from the top of the small room, and no scaffolding boards are placed in the scaffold center. In one example of an embodiment of the scaffold wall finishing work 70 of the present invention, the scaffold 70 for wall finishing works is fixed at two levels - 2 and 4 meters from the floor surface 12 if the height of the ceiling 16 is 7-8 meters from the floor surface 12. However, for wall finishing work The scaffold 70 can also be installed on three or more levels based on the set operating rules and the height of the ceiling of room 16.

Ladders 80

Ladders 80 are mounted so that they pass from the floor of the small room 12 through all scaffold levels.

Handrails 82

Handrails 82 are mounted on the outer edge of the opening (s) on the scaffold 30 for the installation of the equipment or equipment on scaffold 70 for scaffolding, for the installation of equipment or equipment.

The suspended scaffold 10 is temporarily assembled using demountable coupling means and is removed after completion of the installation of the equipment or equipment.

Mounting method using suspended scaffolding

The installation method of the equipment or equipment will be explained below using the hanging scaffold of the present invention.

The construction 11 is loaded into a small room where concrete floor surfaces 12 and wall surfaces 14 are formed, but there is no ceiling 16 (A). Structure 11 includes frame 20, scaffolding 60, scaffolding for wall finishing 70, mounting scaffold 30, ladder 80 and handrail 82. Prior to loading the structure 11 into the small room, the ceiling 11 scaffold 60 is temporarily assembled in the frame 11 for wall finishing work. Scaffold 70 and mounting scaffold 30, and installation scaffold 30 pre-assembles equipment or equipment, such as a pipeline 90. Also, the small room floor surface at level 12 makes an access opening for carrying equipment or equipment. in the small room in the construction 11, the feet of the pillars 22 are mounted on the floor surface 12; from floor surface 12 ceilings in 16 direction 10

EN 6253 B attaches a ladder 80. Ceiling scaffolds 60 are fixed by placing them across the plane, looking from the top of the small room. Scaffolding for wall finishing works is laid in a circle along the walls 14, looking from the top of the small room. Wall cladding scaffolds are centered on 70 screens 82.

Ceiling 16 builds a scaffold 60 (B) of construction 11 ceiling construction. In one example, the ceiling scaffolding is fixed at a height of 5-6 meters from the floor surface 12 when the height of the ceiling 16 is 7-8 meters from the floor surface 12. When the ceiling 16 is formed, scaffolding 60 from the ceiling construction performs finishing and finishing work, such as , ceiling painting 16, as well as works related to the installation of a lift or similar mechanism attached to the ceiling 16. In this way, as the ceiling scaffolding 60 is temporarily assembled in the structure 11 in advance, the ceiling construction work can be carried out shortly after the construction 11 has been loaded.

Further securing scaffold supports 40 using ceiling scaffolding 60, and performing finishing work on the wall surfaces 14 using scaffolding 70 (C) for wall finishing work. The scaffold supports 40 attach the scaffold scaffold 60. In each scaffold support 40, the clamping means 42 of the connecting means 42 and the clamp 45 of the first cylindrical body 45 are temporarily pivoted to the pipe 41.

First, the ceiling beams 18 attached to the ceiling 16 connect the tightening elements 43 of the connecting means 42. After the ends of the beam flange 19 are inserted into the slots of the tightening elements 43, the beam flange 431 is forced by the screws 19 in the thickness direction from the ceiling side to temporarily secure the tightening elements 43 to the beam flange 19. Then, the flange portion 55 of the second cylindrical body 53 is bolted to the flange 23 of the strut 22 by bolt 551. At this time, the compression position of the clamping elements 43 of the connecting means 42 on the beam flange 19 and the clamp 47 extending the tube 41 to accommodate the strut 22 is corrected. , rotate the second shaft 51 with a tool such as an impact wrench to move the second cylindrical body 53 up or down and adjust the position vertically. In this way, the frame 20 can be connected and attached to the ceiling beams 18.

Using scaffolding 70 for wall finishing, it performs wall finishing works such as painting of wall surfaces 14. In one example, the scaffold 70 for wall finishing was fixed at 2 and 4 meters from the floor surface 12 when the height of the ceiling 16 was 7-8 meters from the floor surface.

LT 6253 B

Upon completion of the wall finishing work, it removes the scaffold scaffolding 60, scaffolding for wall finishing 70 and frame 20 and installs hanging scaffolding 10 (D). Hanging scaffolds 10 are fixed at a height where equipment or equipment loading works are performed at the 12 floor level of the small room floor. In one example, the mounting scaffold 30 was fixed to the frame 20 at a height of 3 meters from the floor surface 12, when the height of the ceiling of the small room 16 was 7-8 meters from the surface of the floor 12. {arrangements or equipment 92 moves into the small space through the access opening 13 floor surface 12 level (E). As the frame 11 is removed by the frame 11 on the floor surface 12, and the scaffold 30 for the mounting of the suspended scaffold 10 is mounted at a height at which the equipment or equipment may be carried out, these equipment or equipment 92 may be easily loaded into the small room. Installation work on equipment or equipment 92 is carried out using installation scaffolding 30 (F). Upon completion of the installation work, the suspended scaffold 10 is removed.

According to the present invention, suspended scaffolding and mounting method using such scaffolds - since the suspended scaffolding is mounted in a frame at a height that can be used for loading equipment or equipment - access to the floor can be ensured and equipment or equipment can be easily loaded into a small room. In addition, equipment or equipment may be temporarily assembled or assembled using suspended scaffolding as the main scaffolding, and therefore it is not necessary to dismantle and rebuild scaffolding in accordance with the traditional technology building process. In addition, the frame struts, which are pre-arranged adjacent to the ceiling beams, can be easily suspended from the ceiling beams using scaffold supports, the position of which can be adjusted horizontally and vertically. The hanging scaffold and mounting method of the present invention, using such scaffolds, are particularly useful in the prior art installation of a building where a concrete wall has already been formed.
