Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a capsule for fixing an anchor used when attaching a building material to a base material such as concrete or rock.

[Conventional technology] When attaching various construction materials to concrete, rock, or other base materials, construction is quick and easy, regardless of the base material or installation location, uniform and stable adhesion force can be obtained, and earthquake resistance is achieved. Resin anchors are often used because of their excellent durability.

Such resin anchors are made by separating the reeding force of anchor bolts, deformed steel bars, etc. from uncured resin and its curing agent.
Consists of an anchor fixing capsule sealed in a cylindrical container together with aggregate if necessary, the anchor fixing capsule is inserted into a capsule insertion hole drilled in the base material, and the anchor is fixed from above. The end portion is inserted and the anchor fixing capsule is crushed by applying impact, vibration, rotation, etc., and the uncured resin sealed inside, its curing agent, and aggregate are mixed to harden the uncured resin. This is to fix the anchor to the base material.

As a capsule for fixing an anchor used in such a resin anchor, one having the structure shown in FIG. 11 is generally known.

This anchor fixing capsule is made of a cylindrical capsule body la made of a glass material or the like, and has an uncured resin 2a and an appropriate amount of aggregate 3a mixed therein, and is further formed of a glass capillary and has an uncured resin 2a inside. A hardening agent capsule 5a containing a hardening agent 4a is filled and sealed.

[Problems to be Solved by the Invention] However, the conventional anchor fixing capsule has a problem that the aggregate 3
The forces of a and the uncured resin 2a are distributed over the entire area inside the bulkel body la, and during the fixing work, the aggregate 3a located near the base end and the uncured resin are The resin 2a scatters from the gap between the opening of the capsule insertion hole and the anchor, resulting in a decrease in the pull-out strength.

Further, in the conventional anchor fixing capsule, the curing agent capsule 5a is constituted by a single body having a length extending over the entire area inside the capsule main body la.

Therefore, if the anchor is simply inserted during the fixing work, the curing agent 4a filled inside the crushed curing agent capsule 5a and the uncured resin 2a will hardly mix, so the anchor is attached to a hammer drill or the like and vibrated. There is also the problem that the uncured resin 2a and the curing agent 4a must be thoroughly mixed by rotation or the like, making the fixing work difficult.

Furthermore, as the uncured resin 2a, a synthetic resin having extremely high viscosity and high specific gravity, such as uncured polyester resin or epoxy resin, is generally used. Therefore, if the aggregate 3a is filled first and the uncured resin 2a is poured over it, the uncured resin 2a is filled first and then the aggregate 3 is poured over it.
When filling a into the capsule body Ia, it is extremely difficult and takes a long time to fill it into the capsule body Ia, regardless of the method of pre-mixing the aggregate 3a and the uncured resin 2a. be.

The present invention has been made to solve many of these problems, and it is possible to perform the fixing work with a simple operation of driving an anchor. There is no scattering of uncured resin or aggregate, which does not contaminate the surrounding area, and the uncured resin and curing agent are sufficiently mixed and can be fixed with sufficient pull-out strength. The present invention also provides a capsule that can be easily attached to an anchor.

[Means for Solving the Problem] A first means for solving the problem is that the inside of the sealed capsule body is divided into two chambers on the distal side and the proximal side, and the compartment on the distal side is divided into two chambers on the distal side and the proximal side. is filled with an uncured resin, and the proximal compartment is filled with a curing agent for the uncured resin and aggregate in a mixed state; the second means is a sealed capsule. The interior of the main body is divided into two chambers, one on the distal side and one on the proximal side.The compartment on the distal side is filled with uncured resin, and the compartment on the proximal side is filled with the uncured resin. A configuration in which the agent and aggregate are filled in an alternately layered state; the third means is that the interior of the sealed capsule body is divided into two chambers on the distal side and the proximal side, and the distal side compartment is divided into two chambers. The chamber is filled with an uncured resin, and the compartment on the proximal end side is filled with aggregate having a curing agent for the uncured resin adhered to the surface.

[Operation] The fixed end of the anchor inserted from the proximal side of the capsule for anchor fixation inserted into the capsule insertion hole drilled in the base material crushes the capsule body and fills the compartment on the proximal side. The aggregate and curing agent being pushed are forced to fracture the distal partition plate, and the aggregate, curing agent and fragments of the crushed partition plate are forced into the distal compartment where they are It mixes with the uncured resin filled in the compartment on the tip side. In addition, the aggregate pressed against the bottom of the capsule insertion hole by inserting the anchor, the crushed partition plate, the fragments of the crushed capsule body, and the uncured resin uniformly mixed with the hardening agent are mixed between the anchor and the capsule insertion hole. The gap formed between the anchors is filled, and after a predetermined period of time, the uncured resin hardens and fixes the anchor.

[Example] Next, embodiments of the present invention will be described based on the drawings.

1 to 5 show an embodiment of the first invention, in which a capsule body 1 is formed of a glass material or the like into a cylindrical shape with a bottom, similar to the conventional capsule for fixing an anchor, and has a base end. A cap 3 is fitted into the opening 2 and sealed.

The capsule body 1 also includes a partition plate 4 having an outer diameter approximately equal to the inner diameter of the capsule body I, which is disposed at a predetermined position inside the capsule body 1.
is press-fitted and divided into two compartments, a compartment 5 on the distal end side and a compartment 6 on the proximal end side.

The compartment 5 on the distal end is filled with an uncured resin 7 made of synthetic resin such as uncured polyester resin or epoxy resin, and the compartment 5 on the proximal end facing with the partition plate 4 in between is filled with uncured resin 7. 6 is filled with a curing agent 8 for uncured resin 7 such as granular benzoyl peroxide and aggregate 9 in a mixed state.

In this embodiment, the partition plate 4 press-fitted into the capsule body 1 is
As shown in FIG. 3, a large number of cuts 42 are formed on the surface of a thin plate 41 made of, for example, ceramics or hard synthetic resin. It separates the hardening agent 8 filled into the compartment 5 from the uncured resin 7 filled into the compartment 5, and any other structure may be used as long as it can be easily crushed by the impact of driving the anchor. Of course, it is a good word.

Further, the ratio of the filling amounts of the uncured resin 7, the curing agent 8, and the aggregate 9 is adjusted as appropriate depending on the anchor to be fixed, the base material, etc., as in the conventional anchor fixing capsule.

To manufacture an anchor fixing capsule having such a configuration, first, a predetermined amount of uncured resin 7 is injected into the capsule body l with the opening 2 open, and then the partition plate 4 is inserted into the opening 2. The compartment chamber 5 on the distal side and the compartment chamber 6 on the proximal side are formed by press-fitting and positioning the compartment chamber 6 on the surface of the uncured resin 7.
Then, a predetermined amount of a mixture of curing agent 8 and aggregate 9 is poured to the end of the opening 2, and the opening 2 is covered with the cap 3. Therefore, unlike the conventional anchor fixing capsule shown in FIG. 11, there is no need to fill the uncured resin 2a, the aggregate 3a, and even the hardening agent capsule 5a in a mixed state. It is possible to manufacture.

In this embodiment, the outer peripheral surface of the partition plate 4 is brought into pressure contact with the inner peripheral surface of the capsule body 1 so that the partition plate 4 stays in a predetermined position. A locking stepped portion of the partition plate 4 may be formed between the two by making the diameter slightly smaller than the diameter of the partition plate 4. In this case, the movement of the partition plate 4 is reliably prevented, and the unhardened Since the amount of resin 7 to be injected can be used as a guideline, a predetermined amount can be injected without weighing, and manufacturing becomes easier and faster. Furthermore, the partition plate 4
Even if there is a slight gap between the capsule body 1 and the capsule body 1, if the capsule body is stored and transported in a vertically supported state, the uncured resin 7 in the compartment 5 will be absorbed by the curing agent in the compartment 6. 8 and can be used during normal storage. For example, the curing agent 8 is added to the uncured resin 7 in advance.
The generation of gaps can be prevented by wrapping the partition plate 4 with a soft polyethylene film that is stable and easy to break, or by press-fitting the partition plate 4 through a soft polyethylene film 43 as shown in FIG. If such measures are taken, there is no fear that the uncured resin 7 in the compartment 5 will come into contact with the curing agent 8 in the compartment 6 even if the capsule body is stored and transported horizontally.Furthermore, this embodiment Since the hardening agent 8 in the form of particles was used, it is easier to fill the capsule body 1 than when using the hardening agent 8 in the form of a powder. Although advantageous, other forms such as powder, granules or pellets are also possible.

In order to use the anchor fixing capsule A having such a configuration, first, as shown in FIG.
Insert the anchor fixing capsule A into the capsule insertion hole ll drilled at 0. Then, when the fixed end 13 of the anchor 12 to be fixed is brought into contact with the anchor 12 from above and the proximal end of the anchor 12 is struck with a hammer or the like (not shown), the fixed end 13 crushes the capsule body 1 and the proximal end The hardening agent 8 and aggregate 9 filled in the side compartments 6 are pushed and the partition plate 4 located on the tip side thereof is crushed, and the aggregate 9, the hardening agent 8 and the crushed partition plate 4 are crushed. The fragments are forced into the distal compartment 5, and they and the fragments of the crushed capsule body mix with the uncured resin 7 filled in the distal compartment 5. At this time, in this example, hardening/
Since the fI 18 and the aggregate 9 are in a pre-mixed state, they are uniformly mixed with the uncured resin 7. And anchor 1
2 is deeply inserted, the aggregate 9 pressed to the bottom of the capsule insertion hole 11, fragments of the partition plate 4, and the capsule body l
uncured resin 7 mixed with fragments of and curing agent 8
Since they do not mix with each other, they enter the gap formed between the anchor 12 and the capsule insertion hole 11 and fill the gap in a uniformly dispersed and mixed state, and after a predetermined period of time, the uncured resin 7 hardens and becomes the anchor. 12 is fixed to the base material 10.

In this embodiment, by simply driving the anchor 12, the uncured resin 7, the curing agent 8, the aggregate 9, the capsule body 1, and the fragments of the partition plate 4 are uniformly mixed, and the anchor 12 is fixed with a predetermined pull-out strength. be able to.

Further, FIGS. 6 to 8 show different embodiments of the first invention, and the embodiment shown in FIG.
An opening 16 covered with a cap 15 is formed not only on the proximal end side but also on the distal end side, and the partition plate 4 is formed integrally with the capsule body 1. Therefore, even if the uncured resin 7 and the curing agent 8 are completely isolated and stored for a long period of time, the uncured resin 7 and the curing agent 8 will not come into contact with each other, and the adhesion ability will not deteriorate. , it is not necessary to insert the partition plate 4 during manufacturing, and manufacturing is easy. Further, in the embodiment shown in FIG. 7, a plurality of annular recesses 18 are formed in the peripheral wall 17 of the capsule body l made of glass at appropriate intervals in the length direction.

Therefore, when the anchor is driven in, the driving force is applied to each annular recess 1.
The capsule body 1 is concentrated in the part 8 and is very easily crushed from this part, and the uncured resin 7, the curing agent 8, and the aggregate 9 are mixed very well, and the capsule body 1 itself is crushed as an aggregate. The effect can also be increased.

Furthermore, in the case shown in FIG. 8, the partition plate 4 of the capsule body 1 made of glass is formed by melting and closing the capsule body 1. Therefore, since the uncured resin 7 in the compartment 5 is kept in a completely sealed state, it has the advantage that it can be stored for a long period of time.

FIG. 9 shows an embodiment of the second invention, in which the capsule body 1 is formed of a glass material or the like into a cylindrical shape with a bottom,
A cap 3 is fitted and sealed into the opening 2 located on the proximal end side, and the capsule main body l is separated from the distal end side by a partition plate 4 having an outer diameter approximately equal to the inner diameter of the capsule main body l placed at a predetermined position inside. It is divided into two compartments, a compartment 5 on the side and a compartment 6 on the proximal end side.

The compartment 5 on the distal end is filled with an uncured resin 7 made of synthetic resin such as uncured polyester resin or epoxy resin, and the compartment 5 on the proximal end facing with the partition plate 4 in between is filled with uncured resin 7. 6 is filled with a curing agent 8 of an uncured resin 7 such as powdered or granular benzoyl peroxide and a granular aggregate 9 in alternating layers. The method of use, function, and effect of this embodiment are almost the same as those of the previous embodiment, but in this embodiment, each of the 8 layers of curing agent is pushed by the aggregate 9 located above it during driving, and the compartments on the tip side are 5 and mix uniformly with the uncured resin 7. Therefore, it has excellent miscibility with the uncured resin 7, and can exert a sufficient fixing force even when using a powder or granular curing agent 8 that is difficult to move, especially when an anchor is driven into the curing agent.

FIG. 1O shows an embodiment of the third invention, which is formed of a glass material or the like into a cylindrical shape with a bottom, and a cap 3 is fitted into an opening 2 located on the proximal end side to seal it. The capsule body 1 is divided into two compartments, a compartment 5 on the distal end side and a compartment 6 on the proximal end side, by a partition plate 4 having an outer diameter approximately equal to the inner diameter of the capsule body 1 placed at a predetermined position inside.

The compartment 5 on the distal end is filled with an uncured resin 7 made of synthetic resin such as uncured polyester resin or epoxy resin, and the compartment 5 on the proximal end facing with the partition plate 4 in between is filled with uncured resin 7. The aggregate 6 is filled with an aggregate 9 having a curing agent 8 of an uncured resin 7 such as powdered or granular benzoyl peroxide adhered to the surface using various adhesives, for example.

The method of use, operation, and effect of this embodiment are almost the same as those of the above embodiments, but since the hardening agent 8 is attached to the surface of the aggregate 9, the hardening agent 8 is mixed with the aggregate 9 during driving. It moves to the uncured resin 7 in the compartment 5 on the tip side and mixes uniformly. It also has the advantage that the curing agent 8 and aggregate 9 can be filled at the same time during manufacturing.

Incidentally, the present invention can also be implemented with respect to the capsule body 1 similar to that shown in the embodiments of FIGS. 6 to 8.

In addition, in each of the above embodiments, the capsule body 1 is made of a glass material, etc., but the same method can be applied to an anchor fixing capsule having a capsule body of other structure, such as one made of a synthetic resin film or the like. It goes without saying that you can.

[Effects of the Invention] In the present invention, the capsule body is crushed by the driven anchor, and the partition plate is crushed to push the aggregate and hardening agent filled in the compartment on the proximal end side, and the aggregate, The curing agent and fragments of the crushed partition plate are pushed into the compartment on the distal side, and they and the fragments of the crushed capsule body are mixed with the uncured resin filled in the compartment on the distal side. In particular, since the curing agent is not enclosed in a glass tube or the like and is filled in the capsule body as it is, the uncured resin and the curing agent tend to come into contact with each other instantly and sufficiently, making it easy to insert the anchor. Not only can sufficient pull-out strength be obtained with simple work, but the aggregate located near the proximal end of the capsule body will not be scattered during the fixing work, and the surrounding area will not be contaminated, and the pull-out strength will not decrease. It never comes.

In addition, the uncured resin and aggregate are separated and sealed inside the capsule body, and the hardening agent is directly filled into the capsule body without being enclosed in a glass tube, making it extremely easy and efficient to manufacture. It is something that can be done.
