Description

  The present invention relates to an earthquake-resistant jig for preventing a production device installed in a factory from falling during an earthquake.

Conventionally, L-shaped jigs have been used as earthquake-resistant jigs for preventing the production equipment installed in a factory from falling during an earthquake. In this L-shaped seismic jig, the vertical piece was fixed to the production equipment with bolts, and the horizontal piece was fixed to the floor surface with anchor bolts. However, the above-mentioned seismic jig has a problem that the floor surface is damaged because the anchor bolt is hit on the floor surface every time the production equipment is changed, and the hole of the anchor bolt that has been hit before remains as it is. Therefore, in place of such an earthquake-resistant jig, a T-shaped earthquake-resistant jig 38 as shown in FIG. 7 has been used. In this method, a synthetic resin adhesive 40 used to prevent furniture and electrical appliances from falling over is attached to the back surface of a horizontal fixing plate 39, and the vertical plate is fixed to production equipment with bolts. As another earthquake-resistant jig for production equipment, for example, the invention of Japanese Patent Laid-Open No. 9-189398 is known.

In addition, a seismic jig for production equipment has a fixing nut installed on the upper surface of a horizontal fixing plate provided with an adhesive on the back surface, and a support bolt is screwed into the fixing nut. The body is installed through the upper plate and the lower plate, the upper nut is screwed into the support bolt on the upper surface of the upper plate, and the lower plate is supported by the lower nut screwed into the support bolt. The vertical plate has a plurality of holes for fixing bolts. In addition, it includes that at least one of the plurality of long holes is opened in the horizontal direction and the other is opened in the vertical direction.

  It is possible to provide a seismic jig that exhibits greater seismic performance than conventional seismic jigs. In addition, since the bonding performance is evenly exhibited, it is easy to create earthquake resistance standards for earthquake resistant jigs. In addition, since the adjuster bolt and the earthquake-resistant jig, and the fixing plate and the supporting bolt are pin-joined, almost no moment is generated in the fixing plate.

  Hereinafter, embodiments of an earthquake-resistant jig for production equipment of the present invention (hereinafter simply referred to as an earthquake-resistant jig) will be described. In each embodiment, the same components are described with the same reference numerals, and different configurations are described. Only different symbols will be given for explanation.

  1 to 4 show an earthquake-resistant jig 1 according to the first embodiment. The seismic jig 1 is made of metal and has support legs 3 on both sides of the lower surface of the upper plate 2, a horizontal fixing plate 4 is installed on the lower surface of the support leg 3, and an adhesive is attached to the back surface of the fixing plate 4. An adhesive material 5 such as a sheet is provided, and a pressing plate 6 is overlapped on the upper surface of the upper plate 2.

  A U-shaped cut groove 7 is formed in the center of the pressing plate 6 from one long side to the other long side. Also, the same U-shaped cut groove 8 as described above is formed in the central portion of the upper plate 2, and these cut grooves 7, 8 are overlapped with the cut port 9 side in the opposite direction to insert the adjuster bolt. An insertion hole 10 is formed.

  The circular insertion hole 10 is formed by a semicircular U-shaped portion 11 of the cut groove 7 of the pressing plate 6 and a semicircular U-shaped portion 12 of the cut groove 8 of the upper plate facing each other. An adjuster bolt (support leg capable of adjusting the horizontal level) 13 of the production equipment is inserted into the insertion hole 10 with a slight gap.

  Since the notch grooves 7 and 8 are formed in a U shape in this manner, the earthquake-resistant jig 1 can be attached from the side surface of the adjuster bolt 13, so that the production equipment can be prevented from falling. Further, an upper nut 14 screwed into an adjuster bolt 13 is installed on the upper surface of the presser plate 6, and the upper plate 14 is pressed downward to press the presser plate 6 downward to be predetermined on the adhesive material 5. Then, the fixing plate 4 is brought into close contact with the floor surface 20.

  On the other hand, the lower nut 15 attached to the adjuster bolt 13 on the lower side of the upper plate 2 supports the upper plate 2 and is prevented from loosening between the upper plate 2 and the pressing plate 6 by being tightened to the upper side. Is. That is, the upper plate 2 and the pressing plate 6 sandwiched between these upper and lower nuts 14 and 15 are sandwiched therebetween.

  As shown in FIG. 2, the upper and lower nuts 14 and 15 are halved and can be opened and closed by rotating around the shaft 17 at one end, so that they can be retrofitted to the adjuster bolt 13. Yes. That is, even after the earthquake-resistant jig 1 is attached to the adjuster bolt 13, it is possible to attach it to the lower side of the upper plate 2 and the upper side of the holding plate 6 by opening one end and retrofitting from the side surface of the adjuster bolt 13. Reinforcing ribs 18 are formed on the upper surface of the fixed plate 4 and the lower surface of the upper plate 2 to reinforce the upper plate 2.

  When the adjuster bolt 13 is inserted into the insertion hole 10 in this manner, the adjuster bolt 13 and the earthquake-resistant jig 1 are pin-joined (a slight gap between the adjuster bolt 13 and the insertion hole 10). In addition, since the pin joint portion (the portion of the insertion hole 10) 19 is close to the fixing plate 4, the generated moment can be reduced and the bottom stress can be made uniform, regardless of the accuracy of the production equipment to be fixed. The levelness of the adhesive surface can be ensured.

  Moreover, since the fixing plate 4 can be fixed with the adhesive material 5 (because adhesion is ensured and does not peel off), the production equipment can be easily moved (rearranged), and there is no need to hit anchor bolts on the floor surface. Does not hurt the floor.

  FIG. 4 shows the above-described seismic jig 1 attached to the production device 16. This attachment is performed by first adjusting the horizontal level with the adjuster bolt 13 and then inserting the cut groove 8 into the adjuster bolt 13. The upper plate 2 is installed on the floor surface 20.

  Next, when the notch groove 7 of the presser plate 6 is inserted into the adjuster bolt 13 from the notch 9 side of the notch groove 8 and the presser plate 6 is overlapped with the upper plate 2, they are overlapped vertically. The semicircular U-shaped portions 11 and 12 of the cut grooves 7 and 8 formed face each other to form an insertion hole 10, and the adjuster bolt 13 is inserted into the insertion hole 10.

  Next, as shown in FIG. 2, when one end of the upper nut 14 is opened, and this is attached to the adjuster bolt 13 and tightened downward, the presser plate 6 is pressed downward and the adhesive material 5 is pressed against the adhesive material 5. Is applied to the floor surface 20. Next, when the lower nut 15 is attached to the adjuster bolt 13 in the same manner as described above and is tightened upward to support the upper plate 2 from the lower side, the upper plate 2 and the holding plate 6 are tightened and loosened. And the production device 16 is fixed.

  As described above, since the earthquake-resistant jig 1 is attached to the adjuster bolt 13 by the insertion hole 10 (because there is a slight gap between the insertion hole 10 and the adjuster bolt 13), the frame 21 of the production device 16 is vertical. Even when the degree is not taken, as shown in FIG.

  This is because even if the floor surface 20 is not horizontal, it can be absorbed by a slight gap between the insertion hole 10 and the adjuster bolt 13, so that the floor surface is not horizontal. Even if the fixing plate 4 is bonded to the plate 20, it can be secured without peeling off.

  On the other hand, when the production device 20 is moved by relocation, the upper and lower nuts 14 and 15 are removed from the adjuster bolt 13 and the presser plate 6 is removed from the upper surface, contrary to the above. Then, by removing the adhesive material 5 from the floor surface 20 and removing the fixing plate 4, the production equipment 16 can be moved without damaging the floor surface 20.

  5 and 6 show the earthquake-resistant jig 22 of the second embodiment. The earthquake-resistant jig 22 is a U-shaped joined body 23 that passes through an upper plate 24 and a lower plate 25 and is installed on a support bolt 26. The support bolt 26 is screwed into a fixing nut 28 installed on the upper surface of a horizontal fixing plate 27, and is configured to be pin-connected to the fixing nut 28. Since there is a slight gap between the fixing nut 28 and the support bolt 26, it has the same configuration as the universal joint. An adhesive material 29 such as an adhesive sheet is installed on the back surface of the fixed plate 27.

  A U-shaped joined body 23 is installed on the support bolt 26 through a hole 31 between a horizontal upper plate 24 and a horizontal lower plate 25. The upper surface of the upper plate 24 is screwed into the support bolt 26. An upper nut 32 is installed, and the lower plate 25 is supported by a lower nut 33 screwed into the support bolt 26. Therefore, the joined body 23 can be moved up and down by moving the upper and lower nuts 32 and 33 up and down.

  Further, a long hole 35 for a fixing bolt is opened in the vertical plate 34 of the joined body 23, an upper elongated hole 35 is formed long in the horizontal direction, and a lower elongated hole 35 is formed long in the vertical direction. 23 can be attached to the production equipment 16 with fixing bolts 36. Since the support bolt 26 is pin-joined to the fixing nut 28 in this way, the joined body 23 can be moved slightly back and forth and left and right, and when the joined body 23 is installed in the production equipment 16, it corresponds to the installed state. It becomes possible.

  FIG. 6 shows the above-described seismic jig 22 attached to the production device 16. In this attachment, first, the horizontal level is adjusted by the pedestal 37, and then the fixing plate 27 of the seismic jig 22 is attached to the adhesive 29. Fix to the floor 20 with Next, the joined body 23 is moved up and down by the upper and lower nuts 32 and 33 to match the frame body 21 of the production equipment. And the long hole 35 of the joined body 23 is match | combined with the frame 21 of a production apparatus, and a bolt hole (not shown) is opened in this frame 21. FIG. Next, when the fastening body 36 is fixed by screwing the fixing bolt 36 of the long hole 35 of the joined body 23 into the bolt hole, the production equipment 16 is fixed by the earthquake-resistant jig 22. In addition, this bolt hole 17 can be previously opened in the frame 16, and the long hole 11 of the connection plate 5 can also be match | combined with this.

  Since this joined body 23 can be moved in any direction around the fixed nut 28 by the support bolt 26 (the support bolt 26 and the fixed nut 28 are configured like a universal joint), the frame of the production equipment 16 Even if the verticality of 21 is not achieved, it can follow and can be easily connected to the frame 21. Even if this is a case where the level of the floor surface 20 is not taken, it can be absorbed by the movement of the joined body 23 in an arbitrary direction. Even if 27 is adhered, it can be secured without peeling off.

  On the other hand, when the production device 16 is moved by relocation, the fixing bolt 36 is removed from the long hole 35 of the joined body 23 and the joined body 23 is pulled away from the frame body 21. Next, the adhesive 29 is removed from the floor surface 20 and the fixing plate 27 is removed, so that the production equipment 16 can be moved without damaging the floor surface 20.
