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 is possible to use various constructions for building materials such as bedrock and mounting construction materials without selecting the type of the base material and the mounting position. A fixing capsule in which a reaction-curable main agent and its curing agent are hermetically housed in an isolated state is used because it has a stable fixing force.

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
This is a configuration in which a is mixed and the cap 6a is covered and hermetically sealed. Therefore, it is impossible to crush the capsule 1a and the curing agent capsule 4a to sufficiently mix the reaction curable main agent 2a and the curing agent 3a to obtain a predetermined fixing force only by hitting the anchor at the time of 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, Japanese Utility Model Laid-Open No. 3-103233 discloses a fixing capsule which can perform a fixing work by a simple work of hammering an anchor without using a hammer drill or the like. .

This driving type fixing capsule has a thickness of approximately 5 to 5.
A curing agent is used as an adhesive on the outer peripheral surface of a capsule container made of a cylindrical glass tube having a plurality of squeezed portions containing a reaction curable main agent having a viscosity adjusted by adding 20% by weight of white carbon By adding white carbon to adjust the viscosity of the reaction-curable main agent, the aggregate can be omitted, the reaction-curable main agent can be prevented from sagging during horizontal installation, and driving can be performed. It also measures the reduction of time resistance.

However, it is difficult to finely break the capsule container at the time of driving the fixing capsule, and the curing agent added to the outer peripheral surface does not sufficiently act. The effect of adjusting the viscosity of can not be fully exerted.

In addition, the structure is complicated and not easy to manufacture and is not suitable for mass production, and in addition, a harmful and explosive decomposing hardener such as benzoyl peroxide is exposed on the outer surface. There is a safety problem in the manufacturing process, storage and construction process.

[0009]

DISCLOSURE OF THE INVENTION The problem to be solved by the present invention is to provide a conventionally known hitch-fixing capsule using a reaction-curable main agent whose viscosity is adjusted by adding white carbon. This is because the reaction-curable main agent and the curing agent do not come into sufficient contact with each other, the production is not easy, and not suitable for mass production, but there is a problem in safety.

[0010]

The fixing capsule of the present invention is made of glass in which 0.5 to 20% by weight of white carbon is added to adjust the viscosity of the reaction curable main agent and the curing agent is hermetically sealed. While being housed in the capsule in a separated state, a partition wall formed of a thin layer formed by curing the reaction curable main agent with the curing agent is formed at the interface between the reaction curable main agent and the curing agent. Needless to say, the anchoring work can be performed by a simple work such as hammering the anchor with a hammer etc., of course, omitting the aggregate, and dripping of the reaction curable main agent during horizontal installation. It is possible to prevent, reduce resistance at the time of driving, etc., and it is easy to manufacture, suitable for mass production, and provides an extremely safe fixing capsule in the manufacturing process, storage, and construction process. , To achieve the goal.

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 amount of white carbon added for adjusting the viscosity of the reaction-curable main agent used in the present invention is set to 0.5 to 20% by weight because the amount added is less than 0.5% by weight. The reaction curable main agent will be scattered around during work or will flow out when it is applied to the ceiling or wall. If it exceeds 20% by weight, the fluidity of the reaction curable main agent will decrease and This is because filling becomes difficult.

[0013]

[Function] The safety is ensured by containing the curing agent together with the reaction-curing main agent in a sealed capsule. Further, when the capsule is broken by the anchor that is driven in using a hammer, the exposed reaction-curable main agent and the curing agent are evenly mixed to form a gap formed between the anchor and the capsule insertion hole. After the lapse of a predetermined time, the reaction curable base material is cured and the anchor is fixed. Especially, 0.5 to 20% by weight
By using the reaction curable main agent whose viscosity is adjusted by adding the white carbon, the mixture of the reaction curable main agent and the curing agent can be easily and surely obtained to obtain a sufficient fixing force, and the reaction curing during the driving operation. Prevents the active agent from scattering around or flowing out when applied to the ceiling or walls.

[0014]

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

FIG. 1 shows an embodiment of the present invention. The fixing capsule 1 is obtained by adding 0.5 to 20% by weight of white carbon into a glass capsule 2 sealed by fusion. A reaction curable main agent 3 composed of an unsaturated polyester resin of which viscosity is adjusted, and a powder or granular curing agent 4 containing benzoyl peroxide as a main component are accommodated in two layers in a separated state, and the interface between them is provided. The partition wall 5 is formed of a thin layer having a thickness of about 1 to 2 mm, which is formed by curing the reaction curable base material 2 with the 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. To stop the vibration, 2
4 g of 0.5 to 20% by weight of white carbon is added to fill the 4 layers of the curing agent with the reaction curable main agent 3 made of an unsaturated polyester resin whose viscosity is adjusted.

Next, the upper end of the tubular 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 this fixing 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 three layers of the reaction curable main agent and the four layers of the curing agent.

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

The anchor 11 is inserted into the insertion hole 10 by the tapping force applied to the anchor 11, and the fixing capsule 1 is attached.
Is destroyed, the reaction curable main agent 3 and its curing agent 4 are uniformly mixed, and the gap 13 formed between the anchor 11 and the capsule insertion hole 10 is filled. The anchor 11 is fixed by being cured.

In particular, since the reaction-curable main agent 3 and its curing agent 4 are directly filled in the fixing capsule 1, both are rapidly and uniformly mixed by breaking the fixing capsule 1, but the fixing capsule 1 When the hardener 4 is inserted as the upper side when the capsule 11 is inserted into the capsule insertion hole 10, when the anchor 11 is driven, the powdery or granular hardener 4 becomes the anchor 1.
The compound (1) is rapidly dispersed in the reaction curable main agent 3 and uniformly mixed with the entire reaction curable main agent 3.

Further, since the fixing capsule 1 is entirely made of glass, it can be extremely easily broken by driving the anchor 11, and it is crushed into small pieces to exhibit the function as an aggregate. In particular, since the partition wall 5 that separates the reaction-curable base material 3 and the curing agent 4 in the fixing capsule 1 is formed thin, it can be easily broken by driving the anchor 11, and the reaction-curable base material 3 can be easily broken. On the other hand, since it is a very small amount, there is no fear of adversely affecting the fixing effect.

Furthermore, since the viscosity of the reaction curable main agent 3 is adjusted by adding 0.5 to 20% by weight of white carbon, the reaction curable main agent 3 and the curing agent 4 can be mixed easily and surely. In addition to obtaining a sufficient fixing force, it is possible to omit aggregates, prevent the reaction curable main agent from dripping during horizontal installation, and reduce the resistance during driving, etc. Suitable and extremely safe during manufacturing, storage and construction.

Next, the results of the sticking strength test of the sticking capsules of the present invention shown in this example were compared with those of the comparative example (the amount of white carbon added to the reaction curable main agent was changed under the same conditions as in the above examples. Table 1 together with those).

[0025]

[Table 1]

According to Table 1, when using the reaction curable main agent 3 containing 0.5 to 20% by weight of white carbon, sufficient fixing strength can be obtained and when the resin is applied in the horizontal direction. The reaction curable main agent 3 does not sag, and when the amount of white carbon added is less than the above range, the fixing strength is obtained, but the reaction curable main agent 3 sags when applied in the horizontal direction. It was also confirmed that when the amount of white carbon added was more than the above range, the fluidity of the reaction curable base material 3 was lowered and it was difficult to fill it into the fixing capsule 1.

In this embodiment, the case where the reaction curable main agent 3 and the curing agent 4 are filled has been shown, but 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, it has excellent storability, and when the anchor 11 is driven, it is surely crushed into small pieces to form the reaction curable main agent 3. The curing agent 4 and the curing agent 4 are uniformly dispersed and both are mixed uniformly, but it goes without saying that the present invention can be similarly applied to the case of applying the present invention to the cap-type fixing capsule shown in FIG. 5, for example. .

[0029]

According to the present invention, it is needless to say that the fixing work can be performed by a simple operation of driving the anchor, and it is extremely possible to fill and seal the reaction-curing main agent and the curing agent in the fixing capsule. Since it has a simple structure, it is easy to manufacture and suitable for mass production. Moreover, since the explosive and toxic curing agent is not exposed, it is extremely safe in the manufacturing process, storage, and construction process. 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 sufficient fixing strength, and the reaction curing during the driving operation. There is no possibility that the active ingredient will be scattered around or flow out when it is applied to the ceiling or wall.
