When attaching the handrail support, the base plate is screwed to the back plate from above the coping.
[0004]
[Problems to be solved by the invention]
According to the conventional apparatus for erecting a handrail support on a heddle as described above, a back plate is fixed to the fastener on the parapet in advance, and the back plate is reinforced with the heddle and the handrail support. Since it is necessary to screw the core material at the correct predetermined position, at the stage where the positioning is determined, use a drill to drill through holes for screws from the base plate of the reinforcing core material, screw holes to the back plate, and screw holes to the back plate. Screwing was done by drilling.
[0005]
When such a procedure is taken, it is extremely difficult to accurately drill a hole in the coping and the back plate at the correct position of the reinforcing core. In other words, since the reinforcing core is unstable, it is not only difficult to accurately apply the base plate at the lower end of the reinforcing member to the coping, but even if it is correctly applied, the position of the base plate shifts afterwards, and the holes for screwing are removed. There was a problem that could not be opened correctly, and if you made a mistake it could not be corrected.
[0006]
The present invention has been made in view of the above circumstances, and has as its object to provide an apparatus and a method for erecting a handrail support on a hedder that can accurately set the reinforcing core material of the handrail support.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an upright device according to the present invention is provided with a plurality of latches, which are open crotch-shaped and fixed to a parapet and are arranged in the front and rear in the same direction.

A primary stop screw is passed through so that a position where the base plate at the lower end of the support core is temporarily fixed by screwing a primary stop screw into the back plate can be shifted to the predetermined location. In front of the slot It is characterized in that it has formed the long.
[0008]
The erecting method is to arrange and fix a crotch-shaped fastener on the parapet at the lower end on both sides to hold the cap, and to set the reinforcing core of the handrail support on the cap, In the method of erecting a handrail strut on a heddle in which a base plate at a lower end is screwed from the top of a heddle to a back plate, the fastener is formed with a plurality of hooks for opening the back plate to one of the front and rear sides, respectively. For the screwing, to provide a long hole in the front-rear direction through which the primary stop screw is passed, and by screwing the primary stop screw into the back plate, a reinforcing core is previously attached to the coping, and after attaching the coping, By shifting the loosened primary stop screw along the long hole, the back plate integral with it is engaged with each hook of the fastener, and at the predetermined position of the reinforcing core, tightening of the primary stop screw and secondary stop From the screw base plate By the clamping screwing of the plate, it is characterized in that to determine the fixing of the coping and the reinforcing core for the back plate.
[0009]
[Operation]
Since the erecting device and the erecting method of the handrail support on the cap are configured as described above, the procedure is to fix the fastener to the parapet at a predetermined position, but do not attach the back plate in advance. deep. And, in the state where the base plate of the reinforcing core material is screwed to the back plate with the primary fixing screw and the reinforcing core material is temporarily erected, after attaching the kasagi to the parapet, the primary fixing screw is loosened and the back plate is removed. By shifting it, it is hooked on the fastener.
[0010]
Since the direction in which the back plate is shifted is the front-rear direction, the positioning can be accurately performed so that the reinforcing cores are aligned in a line by shifting the reinforcing cores that are already erected in that direction. In this case, since the reinforcing core is temporarily fixed by the primary screw, there is no deviation. Finally, by tightening the primary stop screw and the secondary stop screw, the correct position is determined, and at the same time, the hooking state of the back plate to the fastener is also determined.
