Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fastening device for fastening a tension member,

More particularly, the present invention relates to a tension member fastener pressing apparatus and a method of installing a fastener fastening apparatus using the same, more specifically, to a tension member fastener pressing apparatus capable of more effectively compressing a fastener type fastening member to a tension member.

1 is a view showing a ductility characteristic in a reinforcement method of a reinforced concrete structure according to the prior art.

The ductility is represented by the ratio of the deformation from the yield to the just before fracture. As shown in FIG. 1 (a), the reinforcing bars behave in a ductile manner and the FRP behaves in a brittle manner. , The reinforced concrete structure can be a brittle structure.

As shown in FIG. 1 b, there is a method in which the ductility of a reinforced concrete structure can be reduced during FRP reinforcement, thereby forming an unattached section optionally in order to secure ductility. However,

As shown in FIG. 1 (c), there is a problem in that rigidity before the yielding of the reinforced concrete structure is lowered when the unattached section is formed arbitrarily.

Therefore, it is necessary to fix the end of the FRP stiffener and to use a minimized settlement area that can be buried on the surface, because the increase of the stiffness is small after using the FRP stiffener lower than the existing stiffener. do.

In addition, the FRP reinforcement is anisotropic material having a lower transverse strength than longitudinal strength and can not be used in a conventional strand fixing apparatus which is fixed by physical force.

Therefore, most of commercially available FRP reinforcements introduce tension by using a special FRP fixing device for fixing.

Particularly, among these methods of fixing the FRP reinforcement, the compression type fixing device has advantages such as reduction of the fixing length and securing of the fixing device in comparison with other methods, but a separate swaging device for manufacturing the fixing device Is required.

2 is a view showing the operation concept of a swaging block device necessary for manufacturing a compression type fixing device according to a conventional technique.

First, as shown in Fig. 2 (a), the compression sleeve 51 is fitted to the FRP reinforcement 14 to align it between the hydraulic jack 52 for extrusion and the swaging block 53 for compression, The hydraulic jack 52 is operated to allow the compression sleeve 51 to pass through the swaging block 53 as shown in Figs. 2B and 2C. At this time, since the inner diameter of the swaging block 53 is smaller than the outer diameter of the compression sleeve 51, a pressing force is generated in the compression sleeve 51 by a forced force.

2 (d), the compression sleeve 51 having passed through the swaging block 53 has the same size as the inner diameter of the swaging block 53 and has a reduced diameter and a longer length To the FRP reinforcement member 14 as shown in FIG.

3A to 3C are photographs illustrating problems of a conventional pressing device.

3A and 3B, there is no guide for guiding the compression sleeve, so that the compression sleeve can not be accurately set on the central axis line, resulting in a decrease in precision And the center of the compression sleeve is inconsistent with respect to the center of the compression sleeve. As a result, as shown in FIG. 3C, there is a problem that the compression sleeve 51 is bent when the compression sleeve is pressed onto the final FRP reinforcement 14. .
