Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is for fixing anchor members such as anchor bolts and deformed rebars to insertion holes formed in concrete, rock and other base materials when mounting various construction and building materials. The present invention relates to a sticking capsule, and more particularly to a sticking capsule capable of carrying out a sticking operation by a simple operation of driving an anchor.

[0002]

2. Description of the Related Art It can be used in various constructions and mounting materials for rock and other base materials without depending on the type and mounting position of the base material. A fixing capsule is used in which a reaction-curable main agent having a stable fixing force and the curing agent are hermetically housed in an isolated state.

As shown in FIG. 5, a conventionally known fixing capsule has a reaction-curable main agent 2a in a cylindrical capsule 1a made of a glass material and a hardening agent 3a of the reaction-curable main agent 2a in a glass capillary. Hardener capsule 4 containing
a, and if necessary, the reaction curable main agent 2a is added to the aggregate 5
It is a structure in which a is mixed, and the cap 6a is covered and hermetically sealed. Therefore, it is not possible to obtain a predetermined fixing force by crushing the capsule 1a and the hardener capsule 4a to sufficiently mix the reaction-curable main agent 2a and the hardener 3a by smashing the anchor during fixing. .

Therefore, the anchor must be attached to a hammer drill or the like, and the anchor must be vibrated and rotated to crush the capsule 1a and the curing agent capsule 4a to mix the reaction curable main agent 2a and the curing agent 3a. It is not easy, and only anchors that can be attached to hammer drills can be used.

Therefore, there is a fixing capsule that can be fixed by a simple operation such as hammering an anchor without using a hammer drill, for example, Japanese Patent Laid-Open No. 60-122400. 63-1
42199, JP-A-1-275681, JP-A-1-310100, and JP-A-3-103233.
It is presented in the official gazette.

However, the driving-type fixing capsule disclosed in the above publication has a constitution in which a curing agent is attached to the outer peripheral surface of a capsule filled with a reaction-curable main agent with an adhesive or the like. The structure is complicated and the manufacturing is not easy and is not suitable for mass production. In addition, the manufacturing process and storage are performed because the curing agent, such as benzoyl peroxide, which is harmful and explosively decomposes is exposed on the outer surface. , There is a safety problem in the construction process.

[0007]

The problem to be solved by the present invention is that the hitherto known sticking type fixing capsules are not easy to manufacture and are not suitable for mass production, but also have a safety problem. That is the point.

[0008]

The fixing capsule of the present invention has a viscosity of 500 to 50,000 centipoise (20).
C., B-type viscometer method), a reaction-curable main agent and its curing agent are separately contained in a sealed glass capsule, and the interface between the reaction-curable main agent and the curing agent is contained. Is characterized in that the reaction-curable main agent is formed with a partition wall made of a thin layer formed by curing with the curing agent, and the fixing work is performed by a simple operation of driving the anchor with a hammer or the like. It goes without saying that it is possible to achieve the object of providing an extremely safe fixing capsule in the manufacturing process as well as in the storage and construction process.

As the reaction-curable main agent used in the present invention, unsaturated polyester resin, epoxy acrylate resin, epoxy resin, etc., and those conventionally used for fixing capsules such as benzoyl peroxide and amines as curing agents are used. It is possible.

Further, the viscosity of the reaction curable main agent used in the present invention is 500 to 50,000 centipoise (2
0 ° C., B-type viscometer method) means that the reaction-curable main agent scatters around or is applied to the ceiling or wall during the implantation work when it is less than 500 centipoise (20 ° C., B-type viscometer method). It will be discharged at the time of 50,000
This is because if it is larger than centipoise (20 ° C., B-type viscometer method), the reaction curable main agent and the curing agent are not sufficiently mixed, and it becomes difficult to obtain the expected fixing strength.

[0011]

[Function] The safety is ensured by containing the curing agent together with the reaction-curing main agent in a sealed capsule. Also, when the capsule is broken by an anchor that is hammered in with a hammer or the like, the reaction curable base compound and its curing agent are mixed uniformly and the gap formed between the anchor and the capsule insertion hole is filled. After the lapse of a predetermined time, the reaction-curable main agent is cured and the anchor is fixed. In particular, the viscosity of the reaction curable main agent is 50
By setting it to 0 to 50,000 centipoise (20 ° C., B-type viscometer method), the mixture of the reaction-curable main agent and the curing agent can be easily and surely obtained and sufficient adhesion can be obtained.
This prevents the reaction-curable main agent from splashing around during the driving operation or from flowing out when it is applied to the ceiling or walls.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 shows one embodiment of the present invention. The fixing capsule 1 has a viscosity of 500 to 50,000 centipoise (20 ° C., B type) in a glass capsule 2 sealed by fusion sealing. Viscosity method) The reaction curable main agent 3 made of unsaturated polyester resin and the powder or granular curing agent 4 containing benzoyl peroxide as a main component are contained in two layers in a separated state and their boundaries are A partition wall 5 is formed on the surface, which is a thin layer having a thickness of about 1 to 2 mm formed by curing the reaction curable base material 2 with a curing agent 4.

Next, an example of the manufacturing method of this embodiment will be described.

2 and 3 show an example of the manufacturing method of this embodiment. First, as shown in FIG. 2, a glass bottomed cylindrical body 6 (outer diameter 17 mm, length 140 mm, thickness 0. (About 8 mm) vertically, and 3 g of a hardening agent 4 containing powdery or granular benzoyl peroxide as a main component is filled from an opening formed at the upper end while vibrating in a vertical direction by a vibrator, and then filled. , Stop the vibration 24
The viscosity of g is 500 to 50,000 centipoise (20
C., a reaction curable base material 3 made of an unsaturated polyester resin adjusted to a B-type viscometer method) is filled on the 4 layers of the curing agent.

Next, the upper end of the cylindrical body 6 (bottoms 7 to 14)
0 mm) is melted with a gas burner 8 and sealed,
Longitudinal vibration (longitudinal amplitude: about 0.2 mm on average) is applied to the fixed capsule 1 for a predetermined time to cause both to react.
A product is obtained by forming a partition wall 5 composed of a thin layer formed by curing the reaction curable main agent 3 on the boundary surface between the reaction curable main agent 3 layer and the curing agent 4 layer.

It should be noted that the viscosity of the reaction curable main agent 3 is 500 to 5
As a means for adjusting to 10,000 centipoise (20 ° C., B-type viscometer method), a method using an additive such as white carbon and a styrene-soluble polymer substance, and a reaction-curable main agent 3 containing styrene and a polymer in an amount ratio of Examples thereof include a method of adjusting the amount, a method of adjusting the degree of polymerization of the reaction curable main agent 3 itself, etc., and an optimal one may be appropriately selected and used depending on the properties and economical efficiency of the reaction curable main agent 3.

In order to use the embodiment manufactured as described above, as shown in FIG. 4, the fixed capsule 1 is inserted into the capsule insertion hole 10 formed in the base material 9 as in the conventional driving type fixed capsule. The anchoring end 12 of the anchor 11 that is to be inserted and fixed is brought into contact with the upper end of the anchoring capsule 1, and the base end of the anchor 11 is tapped with a hammer (not shown).

The tapping force applied to the anchor 11 inserts the anchor 11 into the insertion hole 10 to destroy the fixed capsule 1, and the curing agent 4 is pushed toward the reaction-curable main agent 3 side to form the reaction-curable main agent 3 and its components. The curing agent 4 is uniformly mixed with each other to fill the gap 13 formed between the anchor 11 and the capsule insertion hole 10, and after a lapse of a predetermined time, the reaction curable main agent 3 is cured and the anchor 11 is fixed.

In particular, since the reaction-curable main agent 3 and its curing agent 4 are directly filled in the fixing capsule 1, both of them are rapidly and uniformly mixed by the destruction of the fixing capsule 1.
When the hardener 4 is inserted as the upper side when the fixed capsule 1 is inserted into the capsule insertion hole 10, the powdery or granular hardener 4 is dispersed in the reaction curable main agent 3 by the anchor 11 when the anchor 11 is driven. The reaction curable base material 3 is mixed uniformly.

Further, since the capsule 2 forming the fixed capsule 1 is entirely made of glass, the anchor 11 is formed.
The partition wall 5 which can be broken very easily by the injection of the powder and which is crushed into small pieces to exert the function as an aggregate and which separates the reactive curable main agent 3 in the fixed capsule 1 is Since it is thinly formed, it is easily destroyed by driving the anchor 11 and the reaction curable base material 3
However, since it is extremely small, there is no fear of adversely affecting the fixing effect.

Further, the viscosity of the reaction-curable main agent 4 is 500 to
Since it is adjusted to 50,000 centipoise (20 ° C, B-type viscometer method), the mixture of the reaction curable main agent 3 and the curing agent 4 is made easy and reliable to obtain a sufficient fixing force, and the driving operation is performed. At times, it prevents the reaction-curable main agent from scattering around or flowing out when it is applied to the ceiling or wall.

Next, the results of the sticking strength test of the sticking capsules of the present invention shown in this embodiment are shown in Table 1 together with the results of the comparative examples (those in which the viscosity of the reaction curable base material 3 was changed under the same conditions as in the above embodiments). Shown in.

According to Table 1, it was confirmed that when the viscosity of the reaction curable base material 3 was 500 to 50,000 centipoise (20 ° C., B-type viscometer method), it showed excellent fixing strength.

[0025]

[Table 1]

Although the present embodiment shows the case where the reaction curable main agent 3 and the curing agent 4 are filled, it goes without saying that an aggregate may be further added.

Further, in this embodiment, since the glass cylindrical body 6 is melted and hermetically sealed, the storability and the anchor 11 are maintained.
When the mixture is injected, the reaction curable main agent 3 and the curing agent 4 are surely crushed into small pieces to be uniformly dispersed, and both are uniformly mixed. For example, the cap type fixed capsule shown in FIG. It is needless to say that the same can be implemented when the above is applied.

[0028]

According to the present invention, needless to say, the fixing work can be performed by a simple operation of driving an anchor, and it is extremely easy to fill and seal the reaction-curable main agent and the curing agent in the fixing capsule. Its simple structure makes it easy to manufacture, suitable for mass production, and it is extremely safe in the manufacturing process, storage, and construction process because no explosive and toxic curing agent is exposed. Also, when destroyed by the beating force applied to the anchor, the curing agent is uniformly dispersed in the reaction curable base compound, and both can be mixed rapidly and uniformly to obtain a sufficient fixing strength. There is no concern that the reaction-curable main agent will scatter around or flow out when it is applied to the ceiling or walls.
