Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable walkway used for, for example, hull construction work and other works, and more specifically, it can be installed at any place in any connected state to provide a passageway for workers. A portable walkway for construction that can function as a work scaffold.

[0002]

2. Description of the Related Art In constructing a building such as a ship or a building, in order to secure a so-called work scaffold and a walking path for workers, a space between a piece of a projecting piece on the side of a ship and a horizontal support member such as a beam of a building. A corridor may be erected or suspended in the.

This corridor is, for example, as shown in FIG.
A pair of support girders 1 longer than the space between the horizontal support members, and a plurality of single-pipe pipes 2 spanning the support girders 1 at appropriate intervals.
A plurality of long scaffolding plates 3 placed on the single-pipe pipe 2, a plurality of columns 4 including pipes or the like having their lower ends fixed to the support girder 1 and protruding upward, and the columns 4 And a handrail pipe 6 which is fixed by using a clamp 5 and connects the stanchions 4 in a head-jointed shape.

[0004]

However, since the distance between the horizontal support members for constructing the corridor is not constant and is long or short, the supporting girders 1 and the scaffolding plates 3 forming the corridor are at least horizontally supported. It must be larger than the distance between the timbers, and the scaffolding plate 3 and the supporting girder 1 member of various lengths must be prepared.

Therefore, in order to obtain a desired walkway, it is necessary to prepare scaffolding plates 3 and girder members 1 of various lengths along with a large number of other pipe members, and to store them when not in use. There is an uneconomical need for a large storage space.

Also, when assembling a desired corridor using these members, it is inconvenient to move the long scaffolding plate 3 and the girder member 1, and the assembling work becomes a work at a high place, so be careful. Must be done, and the workability becomes extremely poor.

Further, it is extremely difficult to transfer the assembled corridor to another place as it is at a construction site having a small space, and there is also an inconvenience that a large amount of labor and time are required for the refilling work.

That is, since the scaffolding board 3 and the like are long, it is impossible for one person to carry it. When the operator relocates a narrow space with a plurality of workers or cranes, the long scaffolding board 3 is used for other building materials,
Since it collided with the structure and the direction of travel was difficult to change, the reassembling work was extremely troublesome.

Therefore, the present invention makes it possible to effectively use the space at the construction site and to easily install it, and to freely add and connect as a work passage at the construction site, and also to connect it continuously and vertically and horizontally to a continuous passage or scaffold. The purpose is to provide a pier-shaped portable walkway that can be used as a unit.

[0010]

In order to achieve the above-mentioned object, the structure of the present invention is installed or suspended between horizontal support members such as beam members of a construction to enable a worker to walk or perform various works. In this corridor, the corridor consists of a main corridor and a sub corridor held at one or both ends of the main corridor with its length adjustable, and the main corridor and the sub corridor are located between a pair of frames and the inside of the frame. It consists of a series of scaffolding boards, foldable handrails are attached to the main corridor and sub corridor frames, connecting hardware is attached to the end of the sub corridor frame body, and the upper surface of each scaffold plate Is characterized by being provided with a non-slip.

[0011]

[Function] The length of the corridor is adjusted by sliding the sub corridor.

The corridor can be connected to other corridors by connecting hardware.

The anti-slip prevents slippage when walking on the scaffolding plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a portable walkway for construction of the present invention will be described with reference to the drawings.

FIG. 2 shows an example of the walkway of the present invention.
A main corridor 10 and a sub-corridor 20 which is incorporated into one end or both ends of the main corridor 10 so as to be freely expandable and contractible, and at the tip of the sub-corridor 20, a connecting metal piece 30 for connecting to another corridor Is integrally attached, and further, a hook-shaped hooking metal article 40 is attached to the connecting metal article 30 if necessary.

The sub corridor 20 is supported in the main corridor 10 so that it can be freely moved in and out, and the length of the corridor itself can be freely adjusted. May be adopted.

More specifically, the main corridor 10 comprises a pair of frame girder members 11 and a horizontal scaffolding plate 12 connected between the insides of the girder members 11. The girder members 11 are shown in FIG. As shown in, it is composed of a vertical long box-shaped mold material,
The girder member 21, which is the frame body of the sub corridor 20, is allowed to be inserted therein, and is held so as not to come off in the vertical and outer directions.

Further, this girder member 11 has an opening P along the longitudinal direction inside which faces other girder members 11, and is fixed to the girder member 21 of the sub corridor 20 through this opening P. The scaffolding plate 22 that can be inserted is provided, and the scaffolding plate 12 is provided on the supporting part 11a so as to horizontally project toward the other girder member 11 that faces the upper edge of the opening P. Is fixed.

A rise 11b is formed at the lower edge of the opening P of the girder member 11, and the lower end of the girder member 21 of the sub corridor 20 sliding inside is the girder member 11 of the main corridor 10.
The leg fixing member 13 is fixed between the rising portions 11b and the lower ends of the girder members 11 are prevented from widening, while preventing falling from the inside in the lateral direction and the vertical direction.

Reinforcing parts 11c are formed on the outer upper and lower ends of the girder member 11, but the reinforcing parts 11c are formed so that the outer body part 11d of the girder member 11 has sufficient self-supporting property. Of course, when it is present, the shape may be omitted.

Further, the support portion 11a projectingly formed on the upper end edge of the inner opening P of the girder member 11 is also provided so as to reinforce the inner body portion 11b of the girder member 11. As long as the inner body portion 11e is formed to have a sufficient self-supporting property, the protrusion formation may be omitted.

Needless to say, when the projecting formation of the supporting portion 11a is omitted, the scaffolding plate 12 is connected to the inside of the girder member 11 by using an appropriate connecting metal fitting or the like.

The scaffold plate 12 may be provided inside the girder member 11 of the main corridor 10 as shown in FIG.
It may be provided above or below.

Further, the scaffolding plate 22 of the sub corridor 20 may be located below the scaffolding plate 12 of the main corridor, but as shown in FIG. 13, the scaffolding plate 12 is bolted to the inside lower part of the girder member 11 of the main corridor 10. The scaffolding plate 22 provided on the girder member 21 of the sub corridor 20 that is fixed by welding or the like and slides into the girder member 11 has an opening P.
The scaffolding plate 12 of the main corridor 10 extends more horizontally.
It may be located above.

A scaffolding plate 12 laid in the main corridor 10.
As shown in FIG. 4 (a), is formed in a panel shape made of a metal plate having an appropriate thickness, and has an anti-slip 12a formed in a rib shape on its upper surface at appropriate intervals. is doing.

Although the scaffolding plate 12 is made of a metal panel in this embodiment, it may be replaced with a long scaffolding plate made of plywood or the like.

The point is that it is sufficient if the main corridor 10 is constructed so as to be able to secure a walkway or the like for workers.

Therefore, it is needless to say that the slip stopper 12a formed on the upper surface of the scaffold plate 12 may be formed in a dot shape or a mesh shape instead of the rib shape of the embodiment.

However, if the ribs are formed as in this embodiment, there is an advantage that durability against bending of the upper surface of the scaffolding plate 12 can be increased.

The scaffolding plate 12 according to the present invention has a curved curved surface portion 12b having an inclined surface at one end as shown in FIG. 4B at the end portion of the main corridor 10 so as not to cause a step. The scaffolding board 12c for the end part is used, and the girder member 1 is used.
The scaffolding board 12d having a narrow width as shown in FIG. 4C so that the scaffolding boards 12 and 12c can be laid according to the length of 1
Is used.

The scaffolding plates 12 are connected to each other by using rivets or bolts and nuts.
The connection with 1 is also made by using rivets or bolts and nuts.

Next, the sub corridor 20 is composed of a pair of girder members 21, which are frame bodies, and scaffold plates 22 laid between the girder members 21, and the girder members 21 are slidable within the girder members 11 of the main corridor 10. By moving it, the sub corridor 20 can be freely moved in and out of the main corridor 10.

As shown in FIGS. 2 and 3, the girder member 21 is made of a mold material having an I-shape as a whole, and protrudes to the inner side surface slightly below the center thereof, that is, to the side surfaces facing each other with the other girder member 21. It has the support part 21a formed.

A scaffolding plate 22 is fixed to the supporting portion 21a with rivets or the like.

A reinforcing portion 21c is formed on the upper and lower outer ends of the girder member 21. The reinforcing portion 21c is formed so that the central shaft portion 21f of the girder member 21 has sufficient self-supporting property. Of course, when it is the same, its formation may be omitted.

However, when the reinforcing portion 21c is to be formed, it serves as a guide for inserting the girder member 21 into the girder member 11 of the main corridor 10 and ensures its insertion. The advantages of doing so arise.

The scaffolding board 2 laid in the sub-corridor 20
2 is a scaffolding plate 12 laid in the main walkway 10 described above.
There is no difference in its main composition.

That is, in its cross-sectional shape, FIG.
There is no difference from what is shown in (a), and the upper surface has rib-shaped anti-slip 22a, and the length between the girder members 21 is between the girder members 11 of the scaffolding plate 12 in the main corridor 10. It is only slightly longer than the length.

The scaffolding board 12c having the curved surface 12b as shown in FIG. 4B is not used as the scaffolding board 12 at the end of the sub corridor 20, and the small width as shown in FIG. The only difference is that only the adjustment scaffolding plate 22d may be used.

The end of the auxiliary corridor 20, that is, the girder member 2
A corrugated pipe 23 is interposed between the end portions of 1 to prevent lateral expansion between the girder members 21 and to extend the auxiliary corridor 20 from the main corridor 10 to a desired length. It functions as a handle when pulling out only (see FIGS. 4 and 3).

Therefore, if the girder member 21 of the sub corridor 20 is pulled out from the girder member of the main corridor 10, the length of the entire corridor is increased, and conversely, the girder member 21 of the sub corridor 20 is moved to the main corridor 10. If it is pushed into the girder member 11, the overall length of the corridor will be shortened, and the corridor can be made flexible.

The main corridor 10 and the sub corridor 20 have been described above in detail. The girder members 11 of the main corridor 10 and the girder members 21 of the sub corridor 20 have pin insertion holes 15 at predetermined intervals in their longitudinal directions. And 25 are provided, for example, when the pin 14 is to be inserted as shown in FIG. 3, the extension lengths of the main corridor 10 and the sub corridor 20 are appropriately selected, and the pin insertion holes that overlap at this time are inserted. By inserting the pin 14 into 15 and 25, the main corridor 10 and the sub corridor 20 can be integrally held with a predetermined expansion and contraction length, and the sub corridor 20 can be prevented from coming out of the main corridor 10.

As shown in FIG. 3, the pin 14 has a front end that is bendable and a rear end that is bent so that the girder member 1
It is possible to facilitate the operation of penetrating into the parts 1 and 21 and prevent them from falling off.

When the corridor is positioned at a desired position, the sub corridor 2 is kept suspended while being suspended by a crane or the like.
0 is pulled out from the main corridor 10 by a required length, and the pin 14 is again moved so that the length is maintained.
Let's penetrate 1 here.

The pin insertion holes 15 and 20 can also be used when hoisting and lowering the main corridor 10 and the sub corridor 20 by inserting a pin of a suspender.

Next, the connecting hardware 30 can be fixed to the end of the frame of the auxiliary corridor 20, and the step portion 31 is formed by forming the step portion 31 by making the thickness of the tip side slightly thinner than the center portion. A bolt hole 32 for use is formed.

Therefore, as shown in FIG. 2, a hook 40 may be attached to the connecting hardware 30 by utilizing the bolt holes 32 and 41 to connect to another corridor, or the hook 40 may be attached. Alternatively, it may be connected to the auxiliary corridor 50 described later.

Since the corridor of the present invention is constructed as described above, when it is installed on a construction site, it is transported to a desired installation location and placed on a horizontal support member of the building, for example, a ship. For example, the end of the main corridor 10 or the sub corridor 20 may be placed on a piece protruding from the side of the ship, or on a beam material in the case of a building, or the corridors of the present invention may be connected to each other to form the beam material. Install them in any direction, such as in close proximity and in parallel.

As an example, as shown in the plan view of FIG. 5, the corridor I of the present invention is used to utilize J-shaped A, Y-shaped B and W by utilizing the steel beam b spanning between the steel columns a. Shape C, K shape D,
Parallel type E, orthogonal type F, series type G, zigzag type H, etc. are connected to each other and arranged vertically and horizontally in any direction so that they can be used as passages for workers or scaffolds for work. To

As a result, it can be utilized as a safe and shortest passage to the construction site for the worker, and can also be utilized as a scaffold facing the work site, so that the safety and efficiency of the work can be achieved.

The above J-shape connects the corridors I to each other in the longitudinal direction using the connecting hardware 30, and also connects the corridors I using the auxiliary corridor 50 having a triangular planar shape. Is the three corridors I with the auxiliary corridor 50 interposed.
Are connected in a radial manner, and each corridor I is connected to another corridor I and arranged.

Further, the W shape C uses the auxiliary corridor 50a having a trapezoidal planar shape, and connects three corridors I to one corridor I. These three corridors I are steel beams b and other corridors I. Is an example in which the respective end portions are supported by utilizing, for example, K shape D is a modification of the above I shape A, and an example in which the corridor I is connected to each area of the triangular auxiliary corridor 50 Is.

The parallel type E is for arranging a plurality of corridors I in parallel, the orthogonal type F is for connecting and arranging the corridors I at right angles to each other, and the series type G is for the corridor I in the longitudinal direction. The staggered shape H is an example in which the ends of the corridor I are arranged side by side in the lateral direction.

The above-mentioned series G can be integrally connected in the longitudinal direction by connecting the connecting metal pieces 30 attached to each corridor I.

As for the details of the orthogonal shape F, as shown in FIG. 6, a hook 40 is attached to the end of the sub corridor 20, and the hook 40 is attached.
The girder member 11 of the main corridor 10 corresponds to the girder member 21 of the sub corridor 20.
Hook it down from above and connect it.

The auxiliary corridor 50 used in the J-shape A, Y-shape B, K-shape D, etc. is as shown in FIGS. 7 and 8, and the auxiliary corridor 50 shown in FIG. 7 is a frame body formed in a planar triangular shape. At least the upper surface is closed, and the connecting fittings 51 of the frame are configured to have connecting fittings 51, which are brackets having bolt holes 52, on three sides, and the auxiliary corridor 50 shown in FIG. Instead of the connecting fitting 51 shown in FIG. 7, a hook-shaped hooking member 53, which is a bracket, projects from only one of the three surfaces.

Therefore, in the case of the Y-shape B, the auxiliary corridors 50 having the structure shown in FIG. 7 are used to connect the corridors I, and in the case of the J-shape A or the K-shape D, the auxiliary corridor 5 shown in FIG.
0, the hook metal fitting 53 is connected to the connected corridor I as shown in FIG.
The auxiliary corridor 50 is connected to the other corridor I by fitting it to the girder member from above by bolting the coupling hardware 30 and the coupling fitting 51.

The auxiliary corridor 50a closes at least the upper surface of a flat trapezoidal frame as shown in FIG.
Connecting fitting 5 having bolt holes 52a on both surfaces
It has a configuration in which 1a is provided in a projecting manner, and is suitable, for example, in the case of using a W shape instead of the auxiliary gallery 50 as a modification of the Y shape B.

When applied to the W shape C shown in FIG. 5, the connecting fitting 51a on one surface of the auxiliary corridor 50a.
Instead of this, a hook-shaped hooking metal fitting 53a is provided so as to project, and as shown in FIG. 11, a hooking metal fitting 53a is hooked and connected to the base gallery I.

In this way, by connecting the corridors I to each other in the vertical direction or connecting them in the horizontal or diagonal direction,
It can be freely and easily erected like a pier in the space near the construction site on the construction site, and can be used for necessary work.

At this time, the length of each corridor is set to a length corresponding to the work place by appropriately moving the sub corridor 20 in and out of the main corridor 10 and stopping it with the pin 14.

Further, in FIG. 5, when the corridor I is placed and fixed on the steel beam b, the procedure is as shown in FIG.

That is, the end portion of the expandable corridor according to the present invention is detachably held by the fixing device 60 fixed to the horizontal supporting member such as the beam member.

The fixing device 60 includes a plurality of clamps 61 that are detachably fixed to a horizontal support member and the clamps 6.
1, a bolt 62 projecting from the first plate 63, and a plate 63 fixed by a nut 62a interposed in the bolt 62,
The girder member 2 of the sub corridor 20 is held by the plate 63.
1 and a clip 64 for teaching the lower end.

In the plate 63, when the bolt 62 is inserted, the insertion portion can be arbitrarily selected to have a long hole 63.
a is provided.

Further, the fixing device 60 is constructed so that the lower ends of the pair of girder members 21 of the sub corridor 20 are fixed on the horizontal support member, and each fixing device 60 has the sub corridor 20. Since the width of is preset,
A spacer 65 is arranged between both fixing devices 60 so as to fit the width, and is integrally configured.

Therefore, by fixing the above-mentioned fixing device 60 to a predetermined position of the horizontal support member, the end of the sub-corridor 20 of the corridor moved by a crane or the like can be easily fixed on the horizontal support member. It will be possible.

FIG. 14 shows an example of handling the corridor of the present invention, in which each girder member 11 of the main corridor 10 and the sub corridor 20 is handled.
An example will be shown in which the hoisting tool 70 is attached to the pin insertion holes 15 and 25 by the pin 71, and the hoisting tool 70 is hoisted by a crane or the like to be transported to a predetermined place.

Further, it is possible to use the hanging tool 70 and the pins 71 while the main corridor 10 and the sub corridor 20 are suspended from the building by a wire rope or a chain.

FIG. 15 shows an example in which a stretchable handrail is foldably attached to the corridor of the present invention.
A handrail 80 is installed on the side, and a handrail 90 is installed on the side of the sub corridor 20.

The handrail 80 attached to the main corridor 10 is
As shown in the right side of FIGS. 15 and 16, the girder member 11
The column 81 includes a column 81 whose lower end is foldably supported, and a horizontal member 82 held by the column 81 in a head-jointed shape.

The handrail 90 attached to the auxiliary corridor 20 also has a pillar 91 whose lower end is foldably supported by the girder member 21, as shown in the left side of FIGS. 15 and 16.
And a cross member 92 held by the pillars 91. The handrail cross member 92 has its end portion a handrail cross member 82 of the main corridor 10.
It is inserted inside and is connected so that it can freely move in and out.

The columns 81 and 91 have lower end portions interposed in sockets 83 and 93 fixed to the outer body portion 14d of the girder member 11 or the central shaft portion 21f of the girder member 21, respectively. Long holes 83a, 93a formed in the vertical direction are formed in the sockets 83, 93, and pins 84, 94 formed at the lower end portions of the columns 81, 91 are formed in the long holes 83a, 93a. It is inserted.

Therefore, each of the columns 81 and 91 is attached to its pin 8
4 and 94 are pulled up so as to rise along the long holes 83a and 93a, the lower ends of the columns 81 and 91 are located in the socket 8.
3, 93, disengaged, as shown in FIG.
1, 91 will rotate around the pins 84, 94 and will be folded in the longitudinal direction of the corridor.

In this case, the pins 84 and 94 may be passed through the sockets 83 and 93 in the longitudinal direction of the corridor so that the columns 81 and 91 are folded in the width direction of the corridor.

The horizontal members 82 and 92 are made of round pipes and are held by clamps 85 and 95 pivotally mounted on the columns 81 and 91 in two stages, one above the other.

A handrail cross member 92 of the handrail 90 of the sub corridor 20 is extendably inserted into the handrail cross member 82 of the handrail 80 of the main corridor 10.
Of course, the outer diameter of 2 is smaller than the inner diameter of the cross member 82.

Therefore, when the columns 81 and 91 are raised slightly and then the columns 81 and 91 are folded, the grid-shaped handrails 80 and 90 composed of the columns 81 and 91 and the cross members 82 and 92 are It has a parallelogram shape and is folded in the longitudinal direction of the corridor.

When the pillar 91 of the handrail 90 of the sub corridor 20 is folded, the cross member 92 clamps this.
It can be pulled out from 5, and folded separately from the pillar 91. In this case, the cross member 92 can be pushed into the cross member 82 of the handrail 80 of the main corridor 10 and stored.

The columns 81 of the handrails 80, 90,
The cross-sectional shapes of 91 and the cross members 82, 92 can be arbitrary.

The point is that the columns 81 and 91 are the beam members 11 and 12.
It is held so as to be foldable with respect to 1.
At this time, the horizontal members 82, 92 are rotatably held by the columns 81, 91, and the length of the one horizontal member 82 and the other horizontal member 92 is expandable.

Further, the columns 81 and 91 are composed of the girder members 11 and 12.
Alternatively, it may be detachably held by using a bolt and nut with respect to 1, and foldably held by loosening the nut.

In addition, in the corridor of the above-mentioned embodiment, one sub-corridor 20 is connected to one end or both ends of the main corridor so that it can freely move in and out, but instead of this, the sub-corridor 20 is expanded and contracted in multiple stages. Freely formed, this multi-tiered sub-corridor 20
May be connected to one end or both ends of the main corridor 10 so as to be freely accessible.

FIG. 18 shows a retractable walkway according to another embodiment of the present invention. Although the walkway according to the above-mentioned embodiment has its handrails foldable in the longitudinal direction of the walkway. On the other hand, the walkway according to the present embodiment is different in that the handrails are formed so as to be foldable in the lateral direction above the scaffold plate of the walkway.

That is, in the corridor according to this embodiment, the sub-corridor 20 is attached to both ends of the main corridor 10 so that it can be freely moved in and out. I am able to expand and contract.

The main corridor 10 has the scaffolding plate 12 between the pair of girder members 11, the sub corridor 20 has the scaffolding plate 22 between the pair of girder members 21, and the girder member 21 of the main corridor 10. It is inserted into and out of the beam member 11.

A handrail 80 and a handrail 90 are attached to the main corridor 10 and the sub corridor 20, respectively.

The handrail 80 is constructed so that a horizontal member 82 is integrally connected to a pillar 81 whose lower end is foldably attached to the girder member 11 to form a frame body, and the lower end of the pillar 81 is It is interposed in the socket 83 fixed to the girder member 11.

When the handrail 80 is lifted upward so as to raise the lower end of the column 81, the handrail 80 can be placed on the scaffolding plate 12 of the main corridor 10, that is, can be folded in the lateral direction of the corridor. The lower end of the column 81 and the socket 83 are formed so that

Further, the handrail 90 of the sub corridor 20 is formed by supporting a stretchable cross member 92 such as a chain on a pillar 91 having a lower end foldably attached to the girder member 21, and the lower end of the pillar 91. Is interposed in the socket 83 fixed to the girder member 21.

One end of the horizontal member 92 is locked to the support post 91 and the other end is connected to the end of the handrail 80 of the main corridor 10.

Therefore, if the sub corridor 20 is moved in and out from the end of the main corridor 10, the length of the entire corridor can be expanded and contracted. If the handrail 80 is pulled up, the scaffolding plate 12 of the main corridor 80 of the main corridor 80 can be extended. It will be possible to fold it so that it stacks on top.

Incidentally, the handrail 8 of the main corridor 10 in this embodiment.
As the horizontal member 82 of 0, a member having no elasticity is used, but of course, instead of this, a horizontal member 82 having a high elasticity such as a chain may be used.

The columns 81 and 91 may be detachable from the socket 83.
1. Regarding the constitution of the scaffolding plates 12 and 22, FIG.
Girder members 11 and 21, scaffolding plate 12 in the embodiment shown in
22 has the same configuration.

FIG. 19 shows another mounting example of the present invention. In the above description, the case where the girder members 11 and 21 are placed on the upper surface of the beam or the like is illustrated. Fixing hardware such as a threaded rod 101 through the holding hardware 100 of
Is vertically built and fixed, and a screw 102 is engraved on the outer periphery of the fixed mounting hardware 101. Between the nuts 103 and 104 screwed onto the screw 102, the girder members 11 and 21 are provided.
The support member 105 for mounting the clamp and the clamp member 10b for grasping the lower ends of the girder members 11 and 21 are positioned, and the nut 10
The girder members 11 and 21 are fixedly held by tightening 4.

In this example, the girder members 11 and 21 can be set to an arbitrary height by changing the height positions of the nuts 103 and 104.

When the corridor with handrails is moved to a predetermined installation place as described above, the handrails 80 and 90 are folded, respectively, and when they have been placed at the desired installation place, the handrails 80 and 90 are pulled. A desired handrail can be provided in the corridor by raising and pushing the columns 81 and 91 downward so that the lower ends of the columns 81 and 91 are fitted into the sockets 83 and 93, respectively.

In addition, when carrying out the rearrangement work, the handrail 80,
90 has its support posts 81 and 91 whose lower ends are sockets 83 and 93.
Since it can be made so-called compact by pushing it upward so as to be pulled out from the inside and folding it in the longitudinal direction or the lateral direction of the corridor, the refilling work can be easily performed.

[0100] The corridor of the present invention described above is light in weight when it is made of an aluminum alloy, which is advantageous in handling, and has corrosion resistance even outdoors, and the hook 40 is not attached to the connecting metal fitting 30 directly. Of course, it may be attached to one end of the.

As described above, the corridor of the present invention has the following effects.

The auxiliary corridor is expanded and contracted with respect to the main corridor to set the corridor to a desired length beforehand, and a plurality of corridors set to various lengths are added or connected to suit the construction site. Since it can be installed in any shape and at any height, it can effectively use the space at the construction site and can be erected in the shape of a pier. The work can be shortened, and work safety and efficiency can be improved when the work scaffold is used.

Since each corridor has a connecting hardware,
It can be connected to another corridor, and the arrangement can be easily changed arbitrarily by changing the connection state, and it is possible to easily deal with work at another work place.

As a result, it is possible to omit the ordering of the multipoint members for installing the corridor, the storage thereof, and the preliminary work such as the setup work of the assembling work, and the labor and time for assembling the corridor can be saved. Therefore, it is possible to shorten the construction period of the construction object and reduce the cost required for construction.

By making the corridor expandable and contractable, the entire length of the corridor can be shortened even when the corridor is hung and moved by a crane or the like, or when it is collected or transported when not in use.

Since the foldable handrail is assembled, the handrail can also be folded, so that it can be made so-called compact and can be suspended by a crane.
There is also an effect that it can be easily collected and transported when not in use.

A desired corridor can be provided regardless of the distance between the horizontal support members, and a plurality of corridors can be connected to further lengthen the corridor. There is also an advantage that a worker's walking path and a so-called work scaffold can be secured easily and surely.

Since the anti-slip is formed on each scaffold plate, it is safe because slippage is prevented when walking on the scaffold plate.
