INVENTION The present invention relates to a relates to handrails Tsuke交 <br/> of bracing foldable, between construction locations, monotube scaffold erected adjacently, or between Kenwaku of the pillar , Which contributes to safety including prevention of workers falling on the cloth frame or scaffold plate.

[0002]

BACKGROUND ART As a means on conventionally mounted along the construction locations, scaffolding work safety, interlinked and bracing indicated by sign-26 in FIG. 6, this and a handrail 27 for use by shared mainstream It has become. The ones perforations at both ends of the bracing and handrail as shown below in FIG. 6 in the corresponding holes of Kenchi 1, screws, or pinned to the safety of workers on the bottom of the cloth frame 25 I'm trying.

[0003] As the improvement has rectangular frame indicated by the sign-29 upward in FIG. This is handrail 30 and lower Yokosan 3
1. Consisting of rising portions 32, 32 connecting the two, and a central horizontal member 33 connecting the rising portions, four wings with mounting holes ( not shown ) are provided symmetrically outward from the rising portions 32 . This frame is used by screwing or pinning the hole of the wing to the hole of the building above the cloth frame 28 in the upper part of FIG . In this case, the main body of the rectangular frame plays a role of striking, and the handrail 30 also contributes to the safety of the worker walking on the cloth frame 28 like the handrail 27.

[0004]

[Problems to be Solved by the Invention] In the case of the combination of the conventional handrail 27 and the bracing 26 described above, since these two materials, which are used repeatedly, are separately handled, the storage locations are generally different, and there is a problem in storage. There is. Hitting the attachment to it not only Ken areas, can not be mounted Rukoto at a time both at the pins of the same size in the case of mounting the only muscle paddles, mounted
For shifting the only position to pin the six required for a set. Also those of the latter rectangular frame may be four pins,
It requires the same plane area as a rectangular frame for storage. During storage, the inside of the flat area surrounded by the rectangular outline is wasted space.

[0009] The present invention bracing 3 interlinked with handrail of, both ends of the same
Flip bar-like and handrail pipe 2 of which curved folding direction, Ru is composed of a first pipes 4 two brace members of the second pipe 5. Handrail tube 2
The folding bent portion at both ends projecting vanes 8 and 9 provided respectively mounting holes 6, 7 mounted al are respectively outwardly pivoting the projecting blade 8
First pipe 4 at a location Chakuten 10 is pivotally mounted on the back side, the second pipe 5 at the position of the pivot points 11 are respectively pivotally mounted on the front side to the projecting blade <br/> plate 9. The other ends of the pipes 4 and 5 are provided with mounting holes 12 and 13, respectively. First pipe 4, the second path <br/> type 5 are interlinked in a state where the second path <br/> type 5 placed on the first pipe 4 at the position of FIG plane crosspoint section 14.

[0010] As shown in FIG. 5, Ru elliptical annulus 15 to the crosspoint portion 14 second pie <br/> flop 5 Tei is fixed by Cartesian to example welding. Short radially inward method annulus 15, as can be loosely fitted first pipe 4, Mowazu crab than the diameter outside method of the first pipe 4
Increase . The first pipe 4 is located at the short diameter of the ring 15
It is loosely fitted to the second pipe 5. Crossing part 14 is the second pipe 5
It is formed by the intersection of the first pipe 4 and the second pipe 5 penetrating the inside of the ring body 15 fixed to the second pipe 5 . Annulus 15, since for the first <br/> pipe 4 is loosely fitted in an inclined, major axis dimension of the ring body 15 shall be the size that does not interfere with the inclined state. The first pipe 4 to further <br/> to prevent contact with inclined annulus 15 at the final inclined position of the ring member 15 to the rear predicate piercing rod 16 distal the mounting hole 12 of the
It is planted close to the crossing position at the closer position .

[0011] describes the use of interlinked with handrail of the present invention bracing to the next. First, the first pipe from the folded state of FIG.
4, rotates the second pipes 5 around the pivot point 10 and 11, the first pipe 4 as shown in FIG. 1, the second pipe 5 is then interlinked to form a brace. In this figure, the left and right mounting holes 6,
A line connecting the 13 collimates the line connecting the right upper and lower mounting holes 7 and 12, screwing the respective mounting holes in the upper and lower hole of Kenchi
Because, or the bracing by pinning is mounted between Kenchi parallel, especially same time handrail also attached preparative
You . During this, the line connecting the mounting holes 6, 13, the line connecting the 7, 12
When bets are ing to open toward the handrail tube 2 beyond the parallel,
Pivot points 10, crosspoint 14, angles formed by the mounting hole 13 is larger
And, the inclination of the ring member 15 is the last in the tilted position closer rather I'm thereto relative to the first pipe 4. At this point, the ring 15 comes into contact with the rod 16
Expansion of angles Te, i.e. collapse of parallel lines is prevented, the figure of the right brace is retained.

Next, the storage of the handrail-attached cross brace of the present invention will be described. After use , build crossing braces with handrails
Removed from, the first pipe 4 and the second pipe 5 respectively pivot
Folding is rotated around the wearing points 10 and 11. At this time, although you move in the direction in which the shorter length of the first pipe 4 is interlinked portion crosspoint portion 14 through the inner side of the ring member 15 at 14 and pivot point 10 to be folded, The protruding rod 16 is closer to the tip than the intersection of the first pipe 4
There therefore ram 16 since it is not et those were the annulus 15 both pipes is folded quickly.

[0013] Although not exclusively elliptical illustrated annulus 15, oblong, the first pipe is a ring member such as a rectangle
Because but there is Ruosore shift in the major axis direction, the mounting of the field
Ellipse ring in order to make things easier is preferred more. The first, the length of the second pipe is even equal properly without if mutually parallel lines between the mounting holes on both sides as described above, there is no problem to attach the bracing to Kenchi.
It goes without saying as the real time problems of correct equal lengths of both substantially is more efficient.

[0014]

As has been described above devised], handrail Tsuke交 <br/> of bracing of the present invention may be a bracing and handrail mounting pin four to Kenchi because together , Ru <br/> can achieve a sufficient safety states in the handrail and the bracing in the mounting state. The blocked that <br/> to open more than necessary has a wide angle if provided projecting rod, since it is easily folded Mukoto while moving along the interlinked portion on one of the pipe at the time of folding work
Work is easy, and can be stored in a very small area again
So the excellent effect of.
