It will have a width corresponding to the head. Accordingly, a phenomenon in which the tip of the nail 1 narrower than the head of the nail 1 swings from side to side when the nail 1 strikes, the tip of the nail 1 is drained by the pair of guide pieces 50. Guided correctly into nail holes in (4).

On the other hand, the reinforcement liquid supply device 70 is installed on the upper portion of the guide body 10 so that the reinforcement liquid 3 is supplied to the filling chamber 17 by a predetermined amount.

The reinforcement liquid supply device 70 includes a cylinder 71 installed on the upper portion of the guide body 10, a piston 72 embedded in the cylinder 71 to linearly reciprocate in the longitudinal direction, and the cylinder 71. A reinforcing liquid cylinder 75 for supplying the furnace reinforcement liquid 3, a check valve 79 provided at one end of the cylinder 71 to allow the reinforcement liquid 3 to flow in only one direction, and a sliding body 14. ) And a transfer pipe 74 connected between the piston 72.

The cylinder 71 is horizontally installed in the longitudinal direction on the upper portion of the guide body 14, the reinforcing liquid cylinder 75 is installed at the rear end thereof and communicates with the cylinder 71. In the cylinder 71, a piston 72 is built in, and a compression spring 73 is installed at the rear end of the piston 72 to push the piston 72 forward at all times.

In this case, the sliding range is sufficient so that the hole 78 of the feed pipe 74 is inserted into the piston 72, closed, and then exposed and opened again. Here, a stepped portion is formed around the transfer pipe 74 to limit the sliding range. In addition, the compression spring 73 is formed to gradually reduce the diameter of one end so as to push the feed pipe 74, not the piston 72. As the compression spring 73 pushes the feed tube 74 as described above, when the piston 72 moves backward, the end of the feed tube 74 protrudes due to friction with the inner wall of the cylinder 71, that is, the hole ( 78) is moved to the open state and flows into the transfer pipe of the reinforcing liquid (3). On the contrary, when the piston 72 moves forward, the hole 78 of the conveying pipe 74 is inserted into the piston 72 so that the hole 78 is closed, so that the reinforcing liquid 3 of the reinforcing liquid cylinder 75 becomes a cylinder ( 71) flows into.

In addition, a check valve 79 is provided in a passage through which the reinforcement liquid cylinder 75 and the cylinder 71 are connected, and the check valve 79 has a ball shape to counter current when the piston 72 moves backward. The force automatically prevents the reinforcement liquid 3 from flowing backward by blocking the outlet of the reinforcement liquid cylinder 75 smaller than the ball by the force. In addition, a plurality of protrusions are formed in the inlet of the cylinder 71 into which the reinforcing liquid 3 is introduced, thereby forming a passage through which the reinforcing liquid can be introduced between the protrusions, thereby preventing the ball from being blocked by the above phenomenon.

When the striking device is in close contact with the drainage plate 4 as shown in FIG. 3A, the sliding body 14 moves backward and the transfer pipe 74 connected thereto pushes the piston 72. In this process, when the piston 72 moves forward while the end of the transfer pipe 74, that is, the hole 78 is opened due to the friction with the inner wall of the cylinder 71, the reinforcement liquid 3 is transferred to the transfer pipe through the hole 78. 74 is supplied to the filling chamber of the sliding body (14). At this time, the ball-shaped check valve 79 blocks the outlet of the reinforcing liquid cylinder 75 by the reinforcing liquid 3 to be flowed back so that the reinforcing liquid 3 in the cylinder 71 rides on the transfer pipe 74 smoothly. Transfer. When the sliding body 14 is completely moved toward the guide body 10, as shown in FIG. 3B, the valve packing 18 provided at the tip of the guide body 10 receives the reinforcing liquid 3 in the filling chamber 17. As it is pushed out, it partially flows into the nail hole of the drain plate 4. In this state, when the trigger (T) is pulled to hit the nail (1), the nail (1) penetrates the gate groove (19) of the valve packing (18) and pushes the reinforcement (3) as shown in FIG. 3C. (3) and embedded in the drain plate (4) and concrete wall (W). In this process, the nail 1 is embedded and the reinforcement liquid 3 is filled and hardened in the cracked portion so that the reinforcement is completed. As shown in FIG. 3D, the head portion of the nail 1 exposed to the outside is also reinforcement liquid 3. This coating prevents the corrosion of the nail 1.

Then, when the striking device is spaced apart from the drainage plate 4 in order to nail the nail 1 to another drainage plate 4, the sliding body 14 at the front end protrudes forward and the feed pipe 74 catches the piston 72. In this process, when the piston 72 moves forward, the hole 78 of the feed tube 74 is inserted into the piston 72 so that the hole 78 is closed, so that the reinforcement liquid of the reinforcing liquid cylinder 75 ( 3) is introduced into the cylinder 71 and the preparation for the next supply is completed.

Figure 4a, 4b is a state diagram showing the construction process of the nail striking device for crack reinforcement according to the third embodiment of the present invention, the compression rubber (2) is inserted into the drain plate (4) as shown in the figure It also shows that it can be used.

The compressed rubber (2) has a nail guide groove (2a) in the longitudinal direction therein so that the nail can be inserted, the injection chamber (2b) having a predetermined space on one side is formed, the other side The washer (2c) is attached to prevent the compression rubber from being damaged by the nail hitting.

Therefore, when the sliding body 14 is brought into close contact with the compression rubber 2, the compression rubber 2 is partially inserted into the filling chamber 17, and the sliding body 10 is moved backwards. The reinforcement liquid 3 is supplied from 70, and the supplied reinforcement liquid 3 is injected through the nail guide groove 2a of the compression rubber 2 by the valve packing 18 pushed in and the injection chamber 2b and the drainage plate. Reinforcement liquid 3 flows into the nail hole of (4). In this state, when the trigger T is pulled and the nail 1 is hit, the nail 1 penetrates the valve packing 18 and the drain board 4 and is embedded in the concrete wall W.
