A fixing plate having a through hole in the center is attached to a rectangular space formed by intersecting with each other, and a nut capable of removing a fixing bolt is fixed to one end opening of the through hole of the fixing plate. Reversing device for diaphragm assembly characterized in that positioning rulers arranged opposite to each other with a fixing plate sandwiched therebetween are slidably mounted, and each positioning ruler is provided with a fixing bolt for fixing the positioning ruler to a guide member. It depends on ,.

[0007]

[Action]

 The plate is framed and supported by a guide member provided on a frame-shaped frame that can be rotated in the vertical direction, and each positioning ruler is moved along the guide member to position and fix the corresponding plate, and the air vent hole of the fixing plate. Place the internal reinforcing material on the plate with the outer edges of the four sides aligned with the through holes and the outer edges of the four sides of the plate, and fix the fixing bolts from above from the air vent holes of the inner reinforcing plate and the fixing plate. The internal reinforcing material is fixed to the fixed plate with the plate sandwiched by screwing and tightening the through nut through the through hole. Next, the contact plate is arranged above the outer edges of the four sides of the inner reinforcement so as to vertically overlap with the contact plate, and in this state, the contact plate is attached to one surface of the inner reinforcement by welding, and then the frame is inverted. Then attach the plate to the other side of the internal reinforcement by welding. Therefore, it is possible to reverse the internal reinforcement without using a crane.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

Guide members 2 are provided parallel to each other in the front, rear, left, and right sides of a rectangular frame-shaped frame body 1 to form a lattice, and these guide members 2 intersect each other and are formed in the central portion of the frame body 1. A fixing plate 3 having a through hole 4 provided in the center thereof in the thickness direction is attached to the rectangular space portion. Two positioning rulers 5 are externally fitted to each guide member 2 so as to face each other with the fixed plate 3 sandwiched therebetween and to be slidable as shown in FIG. 3, and one surface (lower surface) of the fixed plate 3 is penetrated. A nut 6 is fixed to the opening of the hole 4, and a fixing bolt 7 with a collar 8 is provided on the nut 6 so that the fixing bolt 7 can be screwed on and off. The b can be fixed to the fixing plate 3 by pressing it through the collar 8.

A receiving plate 9 is provided vertically above the facing portion of each positioning ruler 5, and a fixing bolt 10 is attached to the bottom surface of each positioning ruler 5 so that it can be screwed and inserted. Each positioning ruler 5 is positioned and fixed to the guide member 2 by screwing in the fixing bolt 10 and pressing the lower surface of the guide member 2.

Rotating shafts 11 and 12 are attached to the centers of the outer edges of the opposite sides of the frame body 1. One rotating shaft 11 is attached to a bearing 15 installed on a planting pillar 14 of a base 13. The other rotary shaft 12 is rotatably supported by bearings 17 installed on a pedestal 16 on the base 12, and the gear 19 attached to the output shaft of the reduction gear 18 installed on the pedestal 16 is the rotary shaft described above. A belt 24 is engaged between a pulley 21 mounted on the input shaft of the speed reducer 18 and a pulley 23 mounted on the output shaft of an electric motor 22 mounted on the frame 16 while being meshed with a gear 20 mounted on the gearbox 12. The output of the electric motor 22 is delivered to the rotary shaft 12 of the frame 1 via the reduction gear 18 and the gears 19 and 20, so that the frame 1 can rotate.

The attachment of the contact plate d to the internal reinforcing member b by welding will be described below.

First, the positioning rulers 5 are separated so as to face each other at intervals longer than the length dimension of the contact plate d, and the fixing plate 3 provided on the frame body 1 is framed so as to be surrounded at equal intervals when viewed from above. The contact plate d is arranged on the guide member 2, the facing positioning ruler 5 is moved in the proximity direction, the receiving plate 9 is pressed against the contact plate d to position and fix the corresponding plate d on the guide member 2, and the internal reinforcement b Is placed on the contact plate d so that the air vent hole c is located above the through hole 4 of the fixing plate 3 and the outer edges of the four sides are evenly overlapped with the contact plate d, and the fixing bolt 7 with the collar 8 is inserted from above. The internal reinforcing member b is pressed toward the fixing plate 3 by the collar 8 of the fixing bolt 7 by screwing it into the nut 6 through the air vent hole c of the part reinforcing member b and the through hole 4 of the fixing plate 3. Fix the inner reinforcing member b to the fixing plate 3 by sandwiching the contact plate d with the inner reinforcing member b and the fixing plate 3. It

Then, the abutting plate d is fitted into the gap between the positioning rulers 5 facing each other so as to vertically overlap the lower abutting plate d on the upper side of the outer edge of the four sides of the inner reinforcing member b, and As shown in FIGS. 4 and 5, the contact plate d is positioned and fixed.

As described above, the internal reinforcing material b and the contact plates d arranged on both sides of the four edges of the internal reinforcing material b are fixed to the frame body 1 by the positioning ruler 5, and then contacted with the upper surface of the internal reinforcing material b. The plate d 1 is attached by welding, and then the electric motor 22 is driven to turn over the frame body 1 to attach the lower contact plate d 1 to the lower surface of the internal reinforcing member b by welding. At this time, since the contact plates d arranged in a frame on both sides of the inner reinforcing member b are firmly positioned and held by each positioning ruler 5 and held between the inner reinforcing member b and the fixing plate 3. This is convenient because the contact plate d is maintained at the set position even when the frame 1 is reversed, and it is not necessary to correct the position of the corresponding plate d during welding. Further, as shown in FIG. 5, since the gap 25 is on the lower side of the internal reinforcing member b, the contact plate d can be welded to the internal reinforcing member b after reversing the frame 1 without any trouble.

After attaching the contact plates d to the upper and lower surfaces of the outer edge of the four sides of the inner reinforcing member b by welding as described above, the electric motor 22 is driven to invert the frame 1 to the state shown in FIG. With 8 The fixing bolt 7 is removed from the nut 6 and the positioning ruler 5 is loosened from the fixing bolt 10 to release the positioning fixing state with the guide member 2 and move each positioning ruler 5 in the separating direction. After that, the internal reinforcing material b to which the contact plate d is attached is lifted from the frame 1 by the crane and moved to a required position.

The present invention is not limited to the illustrated and described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
