- FIG. 23 is a partially cutaway explanatory view showing a state where the anchor bolt 3 shown in FIG. 22 is screwed into the hole 30 h of the structure 30.
- both the driving pin 13 and the anchor main body 12 are rotated by the rotary driving bit 22 of the construction tool, and the anchor main body is rotated.
- the evening screw thread 1 2 u formed on the lower outer peripheral surface of 12 is screwed in while forming a female screw on the inner peripheral surface of the hole 30 h of the structure 30.
- the anchor bolt 3 is screwed into the structure 30 in a stable state, and the pull-out holding force also increases.
- FIG. 4 is a partially cutaway explanatory view illustrating a state in which the anchor bolt 3 is fixed. As shown in Fig. 23, the anchor bolt 3 is driven by the construction tool while being rotated, and the thread 12u formed on the lower outer peripheral surface of the anchor body 12 is a hole in the structure 30. The screwing of anchor bolt 3 is completed with part 30h inside.
- the driving pin 13 is driven into the hole of the anchor body 12 with a hammer or the like, so that the tip of the driving pin 13 expands the slit 12 s, and at the same time, the anchor body The tip of the part 12 expands, and the tip presses the inner peripheral surface of the hole 30 h and is fixed to the anchor bolt three-force structure.
- the embodiment illustrated in FIGS. 22 to 24 includes the anchor illustrated in FIG. 14, the presence or absence of a drill bit at the distal end, and the lower outer peripheral surface of the anchor body. The difference is in the presence of the provided tubing threads, and the other configurations are substantially the same.
- the anchor sleeve of the anchor bolt 2 shown in FIGS. 11 to 13 is also used. It can be formed in the same manner as that formed in 15.
- both the driving pin 13 and the anchor main body 12 or the driving pin Although only 13 can be driven to rotate and screwed in, it is also possible to engage the tool XX only with the anchor body 13 to increase the rotational driving force.
- the cross-sectional shape of the upper portion 13a (tool engaging portion) of the driving pin 13 and the cross-sectional shape of the engaging hole 22d of the rotary drive bit 22 of the application tool should be determined. It is not necessary to make the shape into a quadrangle or a polygon.
- the cross-sectional shape of the two may be a circular shape so that no rotational force is transmitted between the two.
- the anchor bolt according to the first invention of the present application is an anchor rod lifting and fixing type, in which both the anchor rod and the anchor sleeve, or the anchor sleeve, are rotationally driven by a construction tool.
- the rotational driving force from the shaft is transmitted sufficiently well, whereby the thread formed on the outer peripheral surface of the anchor sleeve forms a female screw on the inner peripheral surface of the pilot hole of the structure. It is screwed into the pilot hole efficiently while the anchor is stable.
- the thread formed on the outer peripheral surface of the anchor sleeve forms a female screw in the prepared hole of the structure, so that the pull-out holding force of the anchor can be increased.
- a drill bit is provided at the tip of the anchor rod, so that a self-piercing function is added to the anchor, and a structure or a structure is formed by the drill blade.
- An anchor can be driven into a structure while drilling a pilot hole in the structure and the object to be fixed.
- the anchor bolt according to the third invention of the present application is a pin driving fixed type force, Both or one of the anchor main body and the driving pin is rotationally driven, and the rotational driving force from the construction tool is sufficiently transmitted, thereby forming the lower outer peripheral surface of the anchor main body.
- the screw thread is screwed in while efficiently forming a female screw on the inner peripheral surface of the pilot hole of the structure, and is screwed into the pilot hole while the anchor is stable.
- a screw thread formed on the lower outer peripheral surface of the anchor main body portion is provided with a female screw in a prepared hole of the structure, thereby improving the pull-out holding force of the anchor.
- the anchor bolt according to the fourth invention of the present application is configured so that the cross-sectional shapes of the driving pin and the upper portions of the holes of the anchor main body match each other, and the two can integrally rotate. As a result, only the driving force is applied to only the driving pin, and the entire anchor is rotated.
- a drill blade is provided at the tip end of the anchor main body, so that the structure or the structure is not covered by the drill. It is driven while drilling a pilot hole in a fixed object.
- the cutting powder generated from the structure etc. due to the drilling of the drill blade is also discharged to the outside through the pilot hole, and the thread formed on the lower outer peripheral surface of the anchor main body plays a role to eliminate these cutting powder. Will carry it.
- the construction tool according to the sixth invention of the present application is a special tool capable of efficiently driving or extracting the anchor bolt according to the first to fifth inventions into a structure or the like.
- the rotation drive bit when the anchor is screwed or driven, the rotation drive bit is fixed at the distal end side of the outer socket portion.
- the rotational driving force is applied to them to efficiently and efficiently. It can be screwed or driven. After screwing or driving the anchor into the pilot hole, move the rotation drive bit to the base end inside the outer socket and fix it, and then tighten the nut etc. with the outer socket to fix it. Can be.
- the anchor can be removed from the structure by using the construction tool. That is, the rotary drive bit of this construction tool is fixed at the base end position inside the outer socket portion, the outer socket portion is engaged with a fixing nut or the like, and is rotated in the reverse direction of tightening. Remove this, remove the object to be fixed, then drive the anchor rod into the prepared hole with a hammer or the like, and then place the rotation drive bit of the construction tool at the tip of the outer socket.
- the anchor sleeve can be easily pulled out by fixing it, engaging the tip of this rotary drive bit only with the base end of the anchor sleeve, and rotating it in the opposite direction to when the anchor was attached. However, this anchor can be easily removed from the structure.
- the rotation drive bit of the construction tool is fixed at the distal end inside the outer socket portion, and the rotation drive bit is fixed.
- the tip of the bit is engaged with the base end of the driving pin and / or the base end of the anchor main body, so that the anchor can be screwed or driven in efficiently.
- the anchor is fixed to the structure by driving the driving pin into the hole of the anchor body with a hammer or the like.
- the object to be fixed is attached, a nut or the like is screwed in through the washer, and the rotation drive bit is fixed at the base end inside the outer socket, and the outer socket is fixed.
- this dedicated construction tool makes it possible to carry out all or most of the above-mentioned work for anchor bolts, and it is possible to improve the work efficiency and save labor compared to the conventional work. It will be realized.
