Description

[0001] GAP DEVICE FOR LOCKING BOLT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gap holding device for fastening a bolt, and more particularly to a gap holding device for a bolt fastening device used in a portion where a gap is required between a pipe and a bolt fastening such as a clamp and a U- will be.

Generally, there is a case where a gap is required between a pipe and a pipe where a bolt is tightened such as a clamp, a U-bolt, or the like. In other words, a constant gap is required between the pipe and the pipe when clamping or U-bolts are tightened. This gap is adjusted only by fastening bolts and nuts in the field.

The Korean Utility Model Application Publication No. 1999-004269 (1999.01.25) filed by the present applicant has disclosed a welding attachment device for steel structures. 1 is a perspective view showing a conventional welding attaching apparatus.

As shown in Fig. 1, the conventional welding attaching device comprises an integrally injection-molded staple 10, protrusions 12a and 12b and a clearance plate 14, and a height adjustment bolt 16 A fixing bracket 18, and a guide plate 30. The adjusting screw 20 is fastened to the screw hole of the protrusion 12a and the adjusting screw 22 is fastened to the screw hole of the other protrusion 12b. In this case, the adjusting screws 20 and 22 have tapered portions 20a and 20b formed at the lowermost end thereof.

On the other hand, a U-bolt / nut for pipe fixing is disclosed in Korean Utility Model Registration No. 20-0142835 (Jan. 2 is a sectional view showing a state in which a conventional U bolt / nut is installed.

As shown in FIG. 2, a heating coil pipe 20 is disposed on the support member 10. The support member 10 on which the fastening tool 12 is formed is provided with a predetermined gap therebetween, and a U bolt / nut is provided through the fastener 12. U bolt 30 is provided with a U-shaped body 32 so as to maintain a predetermined distance from the outer circumferential surface of the pipe 20 in a state where the U bolt 30 is installed. U-bolts 30 are provided at both ends of the body 32 with a male screw portion 34 smaller in diameter than the body 32 and capable of being inserted into a fastener 12 formed in the support member 10. A screw thread 35 is formed on the outer circumferential surface of the male screw portion 34. The nuts 40 are fastened to the male screws 34, which have passed through the fastening holes 12, respectively.

However, the conventional devices frequently tighten the nut to the end while neglecting the gap requirement when working in the field, so that the circular shape of the clamp or U-bolt is deformed and the gap can not be maintained.

1 is a perspective view showing a conventional welding attachment device,
2 is a cross-sectional view showing a state in which a conventional U bolt / nut is installed,
3 is a side view showing a gap holding device for bolt fastening according to an embodiment of the present invention,
4 is a plan view showing a gap holding device for bolt fastening according to an embodiment of the present invention.

Hereinafter, the technical configuration of the bolt fastening gap holding device will be described in detail with reference to the accompanying drawings.

FIG. 3 is a side view showing a gap holding device for bolt fastening according to one embodiment of the present invention, and FIG. 4 is a plan view showing a gap holding device for bolt fastening according to an embodiment of the present invention.

3 and 4, the apparatus for holding a gap for bolting according to an embodiment of the present invention includes a head 110, a first main plate 150, a second main plate 140, An elevating member 130, and a driving unit.

The head portion 110 is configured to be bent in a "C" shape. At the lower end of the head part 110, a grip part 120 is provided so as to be easily grasped by a worker's hand. The head portion 110 is formed with a groove for allowing the lifting member 130 to be lifted so as to be described later.

The first main plate 150 has a plate shape having a predetermined thickness and is connected to the head portion 110. The first main plate 150 is connected to an upper side of the head unit 110 and is rotatably connected to the head unit 110 in a horizontal direction by a first hinge shaft 151.

The second main plate 140 has a plate shape having a predetermined thickness and is provided to face the first main plate 150. The second main plate 140 is disposed below the first main plate 150. The second main plate 140 is connected to an elevating member 130 to be described later and is connected to the elevating member 130 by a second hinge shaft 141 so as to be rotatable in a horizontal direction.

The first main plate 150 and the second main plate 140 are rotatable by a first hinge shaft 151 and a second hinge shaft 141. When the first main plate 150 and the second main plate 140 are rotated to an appropriate position, So that the interval of the gaps can be appropriately set together with the auxiliary plate to be described later.

The elevating member 130 is slidably connected to the head unit 110 so that the distance between the first main plate 150 and the second main plate 140 is adjusted. The driving unit has a function of slidingly driving the elevating member 130 relative to the head unit 110. The elevating member 130 is connected to the lower part of the head part 110 so as to be able to ascend and descend and the second main plain 140 is connected to the elevating member 130, The spacing between the first main plates 150 is adjusted.
