Description

[Detailed Description of the Invention] This invention relates to a walking handrail support that can be installed extremely easily on the steel structure of a power generation/substation or the like.

Traditionally, walking on the steel structures of power generation and substations was extremely dangerous as there were no supporting shelves.

In order to ensure safety when walking on the steel structure for repairs, patrols, etc., this idea was developed using a steel structure that allows for extremely easy construction of supports on the steel structure and installation of handrails without having to change the existing steel structure. The present invention provides a structure walking handrail support.

The structure of this invention will be explained with reference to the drawings. The inner corner portions of the two substantially L-shaped side plates 1, 1 are brought into contact with the outer corner portion of the contact plate 1a, which has an angular cross section and is to be crimped to the inner side of the angle material of the steel structure. The side plates 1, 1 are fixed to the outside of the abutment plate 1a in parallel with a certain interval, and the ends 2, 2 of each of the two side plates 1, 1 are bent so that they are parallel to each other, and the side plates 1 A flat plate 3 is sandwiched between one side of , 1, and this flat plate 3
The cylinder 4 is clamped and welded adjacent to the both ends 2,
Both ends of a thick plate-shaped door plate 7 are sandwiched between the two, and an eye bolt 5 is passed through one end, and a pin 6 is passed through the other side, so that one end of the door plate 7 can be attached and detached freely, and the other end can be rotated. Be free. A long hole 8 is bored in the center of the door plate 7, and a circular part 10 with a nut hole 9 is provided in the center of the long hole 8 so as to be in contact with both edges of the long hole 8 on both sides. It is integrated with the door plate 7.
The long bolt 11 is inserted into the nut hole 9 of the circular part 10 of the door plate 7, and the tip part 12 is connected to the contact plate 1a of the square plate 1.
It is screwed towards the inside corner. A cylinder 13 is attached to the cylinder 4 with a pin 14, etc., and the cylinder 1
At the center and tip of 3, a grip plate 18 is rotatably provided with a concave part 17 through which a wire rope 16 is passed through two protrusions 15 provided on a cylinder 13. A threaded rod 22 whose roots are rotatably attached to two protrusions 21 similarly provided on the cylinder 13 is passed through the through hole 20 of the veneer 19 provided at the tip, and a thumbscrew 23 is inserted into the outer part of the veneer 19. It is screwed onto a threaded rod 22, and the tip of the grip plate 18 is made detachable.

Since this invention has the above structure, in order to install a handrail support for walking on the steel structure, remove the eye bolt 5 at one end of the door plate 7, and place the pin 6 in the center of the door plate 7.
Open one end from one end 2 of the side plates 1, 1, apply the inside of the contact plate 1a of the side plates 1, 1 to the outside of the horizontal angle member 25 on the steel structure 24, and close the door plate 7 again. Connect the other end of the eye bolt 5 to one end 2 of the side plates 1 and 1, turn the long bolt 11 screwed into the nut hole 9 of the circular part 10, and attach the tip of the long bolt 11 to the inner corner of the angle member 25. When the side plates 12 are crimped, the contact plate 1a is also crimped to the angle material 25 from the outside, so that the side plates 1, 1 are firmly fixed to the angle material 25. The cylinder 4 welded between the side plates 1 and 1 and the cylinder 13 fixed to this with the pin 14 are also firmly fixed. Also, loosen the thumbscrews 23 at the center and tip of the cylinder 13, knock down the threaded rod 22 to open the grip plate 18, and open the concave curved portion 17 of the grip plate 18.
Insert the wire rope 16 inside, close the grip plate 18, and insert the threaded rod 22 into the through hole 20 of the projecting plate 19 of the grip plate 18.
When the wire rope 16 is inserted into the wire rope and the thumbscrew 23 is tightened, the wire rope 16 is clamped by the grip plate 18. In this way, several cylinders 13 are fixed on the steel structure 24, and each cylinder 1
The wire rope 16 is held between the grip plate 18 at the center and/or tip of the wire rope 16.
will be stretched.

Note that the cylinder 4 and the cylinder 13 may be rectangular cylinders or prisms without any problem.

As described above, according to this invention, the side plates 1, 1 of this invention can be extremely easily and firmly fixed to the angle members 20 without changing the structure of the steel structure in a normal power generation and substation, and By fixing the lower part of the column 13 to the side plates 1, 1, the column 13 can be erected on the steel structure 24, and a wire rope 16 for a handrail is attached to the center and/or tip of the column 13.
It is possible to securely hold the handrail, provide an extremely safe walking handrail, and it is also easy to remove from the steel structure 24, making it easy to transport and store after removal.
The cylinder 13 can be removed from the cylinder 4 and disassembled, and is not bulky.
