JPH05318457A - Apparatus for driving chemical anchor bolt - Google Patents

Abstract

PURPOSE:To release below described units from the hands of a worker and to make the labor for positioning unnecessary in the case wherein an anchor bolt is set by a chem. solidification action and a worker successively handles a drill unit, an air unit for cleaning and a hammer drill unit grinding a previously inserted capsule through an anchor bolt and positioned them at each time of handling. CONSTITUTION:Holders H1, H2... for fixing each unit are provided on a rotating plate 7 wherein indexing can be done and after centering is done once, then the centering can be done only by rotating the rotating plate 7 to the next fitting hole fitting with the stop pin.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a placing device in which a so-called chemical anchor bolt is used as an anchor bolt for placing a wall surface or a floor surface.

[0002]

2. Description of the Related Art A chemical anchor bolt, which is fixed by a chemical reaction, is known, unlike a mechanical structure that has long been used for driving anchor bolts. The process in this case consists of the following four points. (1) Drill an anchor bolt driving hole. (2) Use air to remove chips in the hole and clean. (If necessary, rub the inner surface with a brush beforehand.) (3) Insert the capsule containing the flowable chemical substance into the hole. (4) Insert the tip of the anchor bolt into the entrance of the hole. Use a hammer drill (also called impact wrench) to reverse the impact on the anchor bolt, and push the capsule to the specified depth while breaking it. The liquid in the capsule solidifies over time, firmly anchoring the anchor bolt to the hole.

In the above process, an operator has been carrying a drill unit, an air unit, and a hammer drill unit for each process, and centering each one to proceed with the work. Since the number of casts is often a large number, the burden on the operator is large, and it has been desired to develop a device that does not require replacement of the unit and facilitates centering.

[0004]

SOLUTION: Each unit is mounted on a disc that can be indexed and rotated in the order of steps, and if the unit is centered once, the unit can be re-held after that. Is unnecessary.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings will be described. The main body 1 is movably placed on the floor surface and has a vertical groove 1a on the front surface. Foundation 2
Can be moved up and down along the vertical groove 1a, and has a horizontal groove 2a on the front surface. A square bottom plate 3a is fixed to one end of the bearing sleeve 3, and the bottom plate is movable along the horizontal groove 2a. The central shaft 4 is rotatably supported by the bearing cylinder 3 via a ball bearing 3b, and the tip end thereof is a protruding shaft 4a.
Has become. The worm gear 5 is fixed to the protruding shaft 4a, and the worm 6 meshing with the worm gear 5 has both ends axially supported by a bearing cylinder and can be rotated by a handle (not shown) outside the cylinder. The rotary plate 7 is fixed to the other end of the central shaft 4, and has three pin holes 7a formed at equal pitches on the same circumference. A pin cylinder 8 is fixed to the outer edge of the bearing cylinder in parallel with it, and a pin 8a penetrates the pin cylinder 8 and is constantly urged to push in the direction of the rotary plate by an attached spring 8b. The pin 8a can be inserted into the pin hole 7a, and the rotary plate 7 is indexed and positioned by this insertion.

Corresponding to the pin holes 7a, three holders H1, H2 and H3 are fixedly arranged on the rotary plate 7 at equal intervals on the same circumference, and a drill D, a cleaning nozzle N and a hammer drill M are respectively attached to the holders. However, they are mounted so that the forward and backward movements can be adjusted in this order.
(Only the drill D is illustrated in FIG. 2.) As shown in FIG. 4, each holder is provided with a base 9 on a rotating plate, and a sliding plate 9a attached to this is fixed to the shaft end of a pinion gear 9b. It can be moved in and out in the axial direction by rotating the handle 10.

[0007]

[Operation] The construction works are as follows. (1) The main body 1 is placed on the floor, and the base 2 is adjusted and fixed so that the drill D contacts the ruled points on the wall surface at a right angle. (2) Drilling is performed by operating the drill unit D. (3) Remove the pin 8a and turn the worm 6 to rotate the rotary plate 7 to 12
Rotate 0 degrees. Pins are automatically inserted. The inside of the hole is cleaned by operating the cleaning nozzle. (If necessary, brush the hole manually beforehand.) (4) Insert the capsule C into the cleaned hole. (5) Rotate the rotating plate 120 degrees, attach the anchor bolt B to the tip of the hammer drill, and insert it while hitting the capsule. FIG. 5 is a state diagram at this time. (6) If it is left as it is for the processing time, the work is completed due to the solidification of the chemicals. The above is the construction on the vertical wall. For driving on a horizontal floor, the main body is horizontally supported by a plurality of simple legs and the tool is operated downward.

[0008]

[Effect] Each tool unit is released from the operator's hand, and the tool unit can be replaced and positioned simply by rotating the rotary plate. It requires a little operator's assistance when inserting a capsule, but the labor of the operator is significantly reduced.
