Abstract

PURPOSE:To quickly, certainly and firmly fix anchors by extremely simple operation. CONSTITUTION:A device is composed of a deformed differential bar 1 with a wedge part 2 provided to its lower end, a collar 3 with slits 4 for widening and to be fitted to the lower end of the deformed differential bar 1, a cotter 6 approximately in cylindrical shape with slits 7 for thrusting the wedge part therein, and a capsule 9 for sealing up adhesives and to be mounted to the cotter 6. The deformed differential bar 1 is inserted into a fixing hole and the wedge part 2 is thrust into the slits 7 with striking applied from above, and the adhesives are made to flow out with the adhesive sealing capsule 9 broken. The collar 3 is widened, with the cotter 6 widened outwardly, and is made to cut into the inner peripheral wall of the fixing hole. Therefore, firm fixation can be achieved by combined effects of mechanical cutting-in and chemical adhesion.

For example, an anchor fixing structure (Japanese Utility Model Publication No. 63-151615) previously disclosed by the inventor of the present application is known, which will be described with reference to FIGS. 4 and 5. That is, in the figure, 1
Reference numeral 01 is a deformed bar, 102 is a large-diameter head part integrally formed at the lower end of the bar 101, and 103 is a required length formed from the head part 102 toward the upper end of the bar 101 Slits, 104 is a collar with a slit fitted to the lower end of the deformed bar 101, and 105 is the collar 10.
4, a retaining member fixed slightly above the deformed bar 101, 106 is a wedge-shaped cotter inserted into the slit 103 from the lower surface of the head 102, and 107 is a concrete floor. It is a fixed hole.

のである（図５参照）。As shown in FIG. 4, the conventional example constructed as described above is inserted into a fixing hole 107 from which drill powder or the like has been removed, and the lower end surface of the cotter 106 is brought into contact with the bottom surface of the hole. The upper end of the deformed bar 101 is directly hit from above with a hammer or the like, and the cotter 106 is pressed deep into the slit 103 to expand the slit 103 outward. By the expansion operation of the slit 103, the lower ends of the head portion 102 and the deformed bar 101 are expanded outward, and the collar 104 is expanded outward to fix the collar 104 and the head portion 102. It is mechanically fixed by being bitten into the inner peripheral wall surface of the hole 107 (see FIG. 5).

極めて固定作業が面倒で作業能率が悪いものである。In the above-mentioned conventional example, an anchor or the like can be securely fixed in the fixing hole 107, but it has the following drawbacks. First, the cotter 106 is press-fitted into the slit 103. Since the deformed bar 101 itself is expanded, extremely large striking force is required, and the fixing work is very troublesome and troublesome. Second, color-1
Since 04 is indirectly expanded by the cotter 106 via the deformed bar 101, it is always difficult to perform a uniform expansion operation, and the expansion width of the collar 104 is unsatisfactory. It becomes uniform, and it is difficult to always ensure a uniform penetration into the inner wall surface. Thirdly, the slit 103
Further, since the head portion 102 has to be directly formed on the deformed bar 101, the manufacturing thereof is very troublesome and the cost is increased. Fourth
In addition, when drill powder or the like remains in the fixing hole 107, it is not possible to exert a sufficient fixing force, so it is necessary to always clean the fixing hole 107 surely.
Fixing work is extremely troublesome and work efficiency is poor.

っている。As a chemical anchor fixing structure, there is known a structure composed of an adhesive-sealed capsule and a deformed bar having a tip cut at 45 degrees.
Then, such a chemical anchor fixing structure, after inserting the adhesive sealing capsule into the cleaned fixing hole, set the deformed differential streak in an impact wrench etc. and embed it while giving rotation and hitting, and bonding. It is said that the agent-sealed capsule is crushed and the adhesive is allowed to flow out to chemically bond and fix the capsule. However, in such a conventional example, not only the fixing hole after drilling has to be cleaned, but also the deformed bar is adhesively fixed to the fixing hole with an adhesive, so that there is a problem in strength. However, not only is there a lack of certainty, but a relatively large amount of adhesive is required, which leads to an increase in cost as a whole.

Is attached to the lower end of the deformed bar 1, and the tip of the cotter 6 having the adhesive sealing capsule 9 inserted therein is colored-3.
The anchor unit with the wedge portion 2 of the deformed bar 1 partially press-fitted into the slit 7 is fixed in the fixing hole 1
Insert it in 07. After that, the upper end of the deformed bar 1 is hammered downward by a hammer or the like to cause the drill powder 11 to be captured by the capturing portion 8 and the adhesive sealing capsule 9
The wedge portion 2 is pressed into the slit 7 while the adhesive 10 is crushed to flow out the adhesive 10 into the fixing hole 107. Then, the tip of the cotter-6 is gradually expanded outward,
In conjunction with this, the collar 3 also spreads outward along the slit 4, and its lower end gradually begins to bite into the inner peripheral wall surface of the fixing hole 107. At this time, the deformed bar 1 is struck to press the wedge portion 2 into the slit 7 of the cylindrical cotter 6 to expand the collar 3 outwardly.
In comparison with the conventional example in which the collar 104 is expanded outward while the deformed differential muscle 101 itself is expanded by pressing into the slit 103, the fixing work can be easily performed with a small impact force. Further, the deformed bar 1 is hit to cause the lower end of the collar 3 to bite into the inner peripheral wall surface of the fixing hole 107. Then, the mechanical biting action of the lower end of the collar-3 into the fixing hole 107 and the chemical adhesive action of the adhesive 10 flowing out into the fixing hole 107 are combined to firmly fix the anchor ( (See FIG. 3).

And a substantially cylindrical cotter 6 which can be press-fitted into the collar 3 and has a wedge-portion press-fitting slit 7, and an adhesive sealing capsule 9 inserted into the cotter 6. Therefore, after inserting the deformed bar 1 into the fixing hole 107,
The adhesive sealing capsule 9 inserted into the cotter 6 is crushed by a simple operation of hitting the upper end portion of the deformed bar 1 from above to press the wedge portion 2 into the slit 7 of the cotter 6 by pressing. The adhesive 10 is caused to flow out, the cotter 6 is expanded outward, and the collar 3 is expanded to bite into the inner peripheral wall surface of the fixing hole 107, and the mechanical biting action and the adhesive 10 It is possible to fast, surely and firmly fix it in combination with the chemical adhesive action. Further, since the deformed bar 1 is struck to press the wedge portion 2 into the slit 7 of the cylindrical cotter 6 to expand the collar 3 outward,
As compared with the conventional example in which 106 is pressed into the slit 103 to expand the deformed bar 101 itself and the collar 104 is expanded outward, the fixing work can be performed very easily with a small impact force. It can be done.
