Description

  The present invention relates to a nailing unit, a nailing tool, a nailing machine, and a construction method.

Conventionally, nailing machines using compressed air have been widely used when building materials such as plate materials (placed materials) are struck onto the chassis. By driving the scissors, the workpiece can be easily fixed to the housing. In the nailing operation performed using such a nailing machine, it is very difficult to drive the nail perpendicular to the surface of the housing and the material to be driven, and this work requires skilled skills. It is done. If the nail is not driven perpendicular to the surface of the housing to be driven, the length of penetration into the nail housing is shorter than when the nail is driven vertically, and the housing and the There was a problem that the reliability of the mounting strength with the insert was reduced. Further, when the inclination of the nail becomes larger than a certain level, there is a possibility that the nail will bounce back without penetrating into the housing. Therefore, a nailing machine capable of driving a nail almost vertically is disclosed in, for example, Patent Document 1 below.

As shown in FIGS. 1 and 2, the nail driver 10 mainly includes a power transmission portion 14 that transmits air pressure to a piston 12 that incorporates air pressure, and an injection portion 16 that transmits movement of the piston 12 to a nail described later. Has been. The nailing machine 10 is a device for injecting a nail for placing a glass wool heat insulation board (a material to be driven) on a concrete frame, and its basic components and functions are generally known. It is almost the same as a conventional nailing machine.

  A tube 18 for introducing compressed air is attached to the power transmission portion 14, and a trigger 22 is provided on the handle portion 20 of the power transmission portion 14. When the trigger 22 of the handle portion 20 is pulled, the piston 12 is instantaneously moved by the air pressure of the compressed air introduced from the tube 18. On the other hand, a jig (a nailing machine jig) 24 is attached to the injection portion 16. Reference numeral 23 denotes a trigger lock sensor that detects a pressure applied to the jig 24 and prevents malfunction of the piston 12. Hereinafter, the jig 24 will be described in detail with reference to FIGS. 2 and 3. FIG. 3 is a schematic perspective view showing a nail driving unit according to the embodiment of the present invention.

  As shown in FIGS. 2 and 3, the jig 24 has an outer diameter larger than that of the cylindrical cylinder portion 26 through which the piston 12 is inserted and the cylinder portion 26 formed coaxially at one end portion of the cylinder portion 26. It is composed of a large cylindrical holder portion 28 and three guide pins 30 of the same length that are erected from three screw holes 29 provided on the end surface 28a of the holder portion 28. In addition, the nail driving unit 31 (refer FIG. 3) which concerns on embodiment of this invention is comprised by the jig | tool 24 mentioned above and the nail mentioned later.

  Of the inner peripheral surface 26a of the cylinder portion 26, a tapered portion 26b having a diameter that increases toward the end surface is formed at the end opposite to the holder portion 28 side, and the holder portion 28 is located near the center portion. A stepped portion 26c having a larger diameter on the side is formed. On the other hand, on the outer periphery of the cylinder portion 26, a chuck portion 26d for fixing the nail driver 10 and the jig 24 is formed.

  The inner diameter of the holder portion 28 is the same as the inner diameter of the cylinder portion 26 on the holder portion 28 side. An annular wall 28b perpendicular to the end surface 28a is provided upright on the outer edge of the end surface 28a of the holder portion 28, and a magnet (not shown) is built in the holder portion 28, so that the nail can be held more securely. It is illustrated. The three screw holes 29 provided in the end surface 28 a of the holder portion 28 extend from the end surface 28 a of the holder portion 28 by the same length parallel to the axis of the cylinder portion 26 and the holder portion 28, and the cylinder portion 26 and the holder portion 28. These are arranged at intervals of 120 degrees with reference to the axis of.

  One end portion 30a of the three guide pins 30 is formed with a screw portion, and the guide pin 30 is screwed so as to extend in the same direction as the extension direction of the screw hole 29 described above. Therefore, the guide pins 30 also extend parallel to the axis of the cylinder part 26 and the holder part 28 and are arranged at an angular interval of 120 degrees with respect to the axis of the cylinder part 26 and the holder part 28. The other end 30 b is sharpened at the free end, and any end 30 b is located on one virtual plane 32 perpendicular to the extending direction of the guide pin 30.

  Next, the nail that is attached to the jig 24 and forms the nail driving unit 31 with the jig 24 will be described with reference to FIGS. 2 and 3. The nail 34 includes a substantially disk-shaped plate (flange portion) 36 having a through hole 36 a at the center, and a shaft member (shaft portion) 38 that penetrates the through hole 36 a of the plate 36.

  The plate 36 has an outer diameter slightly smaller than the inner peripheral diameter of the annular wall 28b so as to fit into the annular wall 28b of the holder portion 28 described above. Further, the plate 36 has a guide hole (guide portion) 36 b penetrating at a position corresponding to the guide pin 30 erected from the end surface 28 a of the holder portion 28, and when the plate 36 is fitted to the annular wall 28 b of the holder portion 28. The guide pin 30 is inserted into the guide hole 36b. The shaft member 38 includes a body portion 38a having a diameter smaller than that of the through hole 36a of the plate 36, a head portion 38b locked to the edge of the through hole 36a, and a sharpened tip portion 38c. The body portion 38a is formed with a stepped portion 38d having a small diameter on the side of the distal end portion 38c.

  Then, when the shaft member 38 is inserted through the through hole 36a of the plate 36 from the tip end portion 38c side, the nail 34 in which the plate 36 extends perpendicularly to the axis of the shaft member 38 is completed. Further, the nail 34 is fixed to the jig 24 so that the shaft member 38 is inserted through the through hole 36a of the plate 36 from the tip end portion 38c side, and each guide pin 30 is inserted through the guide hole 36b of the corresponding plate 36. The preparation of the nail driving unit 31 is completed. When the nail 34 is attached to the jig 24, the plate 36 is fitted into the annular wall 28b of the jig 24 and is held firmly. Further, the nail 34 is securely held by the jig 24 until it is ejected by the magnet built in the holder portion 28.

  When the nail 34 is mounted on the jig 24, the plate 36 supported by the three guide pins 30 is perpendicular to each guide pin 30. Therefore, the shaft member 38 extending perpendicularly to the plate 36 extends parallel to the guide pin 30. Further, the head portion 38b of the shaft member 38 is inserted into the holder portion 28 and the cylinder portion 26 of the jig 24 and abuts against the side surface of the step portion 26c. At this time, the position of the tip end portion 38c of the shaft member 38 is located closer to the jig 24 than the virtual plane 32 described above.

  Next, a procedure for attaching a heat insulation board to a concrete frame using the nailing unit 31 described above will be described with reference to FIG. FIG. 4 is a view showing a state where the nail is ejected.

  First, using the chuck portion 26d of the cylinder portion 26 of the jig 24, the above-described nail driving unit 31 is attached to the injection portion 16 of the nail driving machine 10, and the nail driving unit 31 is attached to the surface of the heat insulating board 40 (to be driven). Face) 40a. Then, the shaft member 38 and the guide pin 30 of the nail driving unit 31 pressed against the heat insulation board 40 penetrate the heat insulation board 40. Then, the nail driving unit 31 is further pressed toward the heat insulation board 40 until the end portions 30b of the three guide pins 30 penetrating the heat insulation board 40 come into contact with the surface 42a of the concrete housing 42 (see FIG. 4A). ). Thus, when each end 30b of the guide pin 30 contacts the surface 42a of the concrete housing 42, the axis of each guide pin 30 and the surface 42a of the concrete housing 42 intersect perpendicularly. As described above, since the shaft member 38 extends in parallel to the guide pin 30, the shaft member 38 also extends perpendicularly to the surface 42 a of the concrete housing 42, like the guide pin 30. .

  Next, when the trigger 22 of the handle portion 20 is pulled and the piston 12 of the nailing machine 10 moves instantaneously and passes through the cylinder portion 26, the head 12a of the piston 12 strikes the head portion 38b of the shaft member 38. Hit. When the head portion 38b is hit, the tip portion 38c of the shaft member 38 comes into contact with the surface 42a of the concrete housing 42 and further enters the concrete housing 42 (see FIG. 4B).

  When the shaft member 38 further moves and its head portion 38b comes into contact with the plate 36, the shaft member 38 and the plate 36 move integrally with the head portion 38b locked to the edge of the through hole 36a. To do. Thereby, the plate 36 firmly presses the heat insulation board 40 against the concrete frame 42. When the shaft member 38 and the plate 36 move integrally, the guide pins 30 guide the plate 36 in a state where the guide pins 30 are inserted through the guide holes 36b. On the other hand, when the tip portion 38c of the shaft member 38 enters the concrete housing 42 and the stepped portion 38d reaches the surface 42a of the concrete housing 42, the shaft member 38 suddenly becomes difficult to enter the concrete housing 42. It will not penetrate (see FIG. 4C). That is, the amount of entry of the nail 34 into the concrete housing 42 is adjusted by the step portion 38d provided on the trunk portion 38a. Preferably, the length of the head portion 38b and the step portion 38d and the thickness of the heat insulating board 40 are adjusted. As long as they are substantially the same. In this case, since the situation in which the plate 36 presses the heat insulation board 40 more than necessary is suppressed, the occurrence of wrinkles that impair the beauty of the heat insulation board 40 is significantly suppressed.

  As described in detail above, the jig 24 is attached to the injection portion 16 of the nailing machine 10. The jig 24 is provided with three guide pins 30. And these guide pins 30 penetrate the heat insulation board 40, and the end 30b of each guide pin 30 contacts the surface 42a of the concrete housing 42, so that each guide pin 30 is perpendicular to the housing surface 42a. In this state, the jig 24 is held. When the nail 34 is ejected toward the heat insulation board 40 with the jig 24 held in this manner, the shaft member 38 of the nail 34 penetrates the heat insulation board 40 and enters the housing 42. The plate 36 presses the heat insulating board 40 against the housing 42.

  When the nail 34 is ejected, the plate 36 extending perpendicularly to the shaft member 38 of the nail 34 is guided in a state where the guide hole 36 b is inserted into the guide pin 30. Therefore, the shaft member 38 of the nail 34 is guided in the extending direction of the guide pin 30, and the nail 34 is driven perpendicular to the housing 42. Thus, since the nail driving machine 10 injects the nail 34 with the three guide pins 30 penetrating the heat insulation board 40, the case can be obtained even when the heat insulation board 40 having high flexibility is struck against the case 42. It is possible to nail perpendicularly to 42. Thereby, it becomes possible to always keep the length of the nail 34 entering the housing 42 constant, and the reliability of the mounting strength of the heat insulating board 40 is improved.

  Further, in the nail 34, the shaft member 38 of the shaft portion and the plate 36 of the flange portion are separate, and there is a slight gap between the body portion 38a of the shaft member 38 and the through hole 36a of the plate 36. Even when the shaft member 38 is not driven perpendicularly to the surface 40 a of the heat insulating board 40, the heat insulating board 40 can be firmly pressed against the housing 42 by the plate 36 being slightly inclined with respect to the shaft member 38. Further, when the shaft member 38 and the plate 36 are separate bodies, the shaft member 38 and the plate 36 can be stacked separately, which facilitates packing and storage. As the nail 34, a shaft member 38 and a plate 36 that are integrally formed as appropriate may be adopted.

  The present invention is not limited to the above embodiment, and various modifications are possible. For example, the guide portion of the plate (flange portion) is not limited to the hole, and may be a notch provided on the outer edge of the plate. Further, the number of guide pins may be four or five as long as it is three or more. Furthermore, as long as the material to be driven is a highly flexible material, it is not particularly limited to a glass wool heat insulating board, and may be a heat insulating board made of a ceramic material, for example.
