Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is for an adhesive post-installed anchor that is inserted into a buried hole of an anchor bolt, and the anchor bolt is embedded from above to fix the anchor bolt in the buried hole. Multiple adhesive glass capsules (hereinafter simply referred to as capsules)
It is about.

[Prior Art] Conventionally, when attaching a post-installation anchor to a structure such as reinforced concrete, a concrete body is drilled using a drilling machine of an electric tool, and after cleaning the hole, an adhesive is inserted into the anchor bolt. There is a method of attaching an anchor bolt and a method of mechanically attaching an anchor bolt using a metal expansion anchor.

Adhesive post-installation anchors include capsule-type and injection-type. As a general capsule-type shape, the main component of the adhesive and the hardener component are separated into a cylindrical glass tube or thin-film plastic tube container. What is contained is known.

[Problems to be Solved by the Invention] In an adhesive-type post-installed anchor using a capsule containing an adhesive, one or more capsules are inserted into a hole for burying the anchor bolt, and the anchor bolt is inserted from above. The adhesive components can be agitated and mixed and hardened and fixed by rotating and inserting, but long capsules and short capsules that match the embedding depth of the anchor bolt are required.

However, it is uneconomical to prepare capsules of various lengths for anchor bolts of the same diameter, and improvement thereof is desired.

Further, in the conventional capsule containing an adhesive, the main component and the curing agent component or the aggregate component are sealed in the capsule by a double pipe system. For example, as in the conventional example shown in FIG. 3, in a tubular glass tube that is a capsule container 1, a main agent component 2, an aggregate component 3, and a hardening agent component 5 contained in a thin tubular glass tube 4 are placed. There is a capsule containing adhesive. Since each is sealed with a double tube method, the capsule is finely processed, for example, 5 cm in length
It is very difficult to manufacture capsules having the following small dimensions, and shortening of capsules is desired.

The present invention solves the above-mentioned problems and folds the capsules into plural pieces by subjecting the adhesive-containing capsule to one or several locations in the longitudinal direction which are fragile so that the capsule container can be easily cut by hand force. It can be used as a capsule of a book, and it is easy to select capsules on site for various drilling depths of anchors by adjusting cutting dimensions, and capsules with a short size of 2-3 cm, which was difficult to manufacture in the past, are long capsules. It is possible to make it possible to fold it into short pieces, and further to provide a multiple adhesive capsule for an adhesive-type post-installed anchor that also leads to a reduction in manufacturing unit price.

[Means for Solving Problems] In order to solve the above problems and achieve the object of the invention, the multiple adhesive capsule for adhesive-type post-installed anchor according to the present invention is configured as follows. And That is, in the adhesive-containing capsule used for the adhesive post-installed anchor for fixing the anchor bolt to the burial hole, the capsule is processed at one or more locations in the longitudinal direction of the capsule container so that it can be easily cut with the capsule container. The main component of (1) is contained in a capsule, and the solid curing agent component is attached to the outer peripheral portion of the capsule container, and can be cut into an appropriate length for use.

The multiple adhesive capsule for an adhesive post-installed anchor according to the present invention relates to an adhesive-containing capsule used for an adhesive post-installed anchor for fixing an anchor bolt to an embedding hole.

The capsule container is processed at one or more locations in the longitudinal direction of the capsule container so that the capsule container can be easily cut. The main ingredient component of the adhesive is contained in the capsule container, and the solid curing agent component is the outer peripheral portion of the capsule container. It is attached to.

Here, the processing capable of easily cutting the capsule container means, for example, flaw processing, strain processing, narrowing processing and the like. Scratch processing is processing that makes a thin incision on the outer circumference of the tube surface with a diamond cutter, processing that treats the surface of the container with hydrofluoric acid solution etc. to make scratches, etc.Strain processing is glass tube and glass tube Due to the difference in expansion coefficient with the glass paint printed on the surface of the
This refers to a process in which a strong tensile stress is generated in the printed portion of the glass paint to cause strain in the container, or the glass tube is subjected to a drawing process to cause strain in the container. Examples of the glass paint include glass paint containing lead.

Further, to be able to cut the capsule container mainly means that the capsule container can be cut by folding it by hand, but it may be cut by using another file, knife, scissors or the like. The capsule container is cut and formed so that it can be divided into many pieces, so that it can be said to be a multiple type.

As the adhesive, an unsaturated polyester resin, an epoxy acrylate resin, an acrylic resin, or the like having an organic peroxide of a thermosetting resin as a curing initiator can be used.

Embodiments Embodiments of the present invention shown in the drawings will be described in detail below.
FIG. 1 is a partially cutaway front view of the first embodiment, and FIG. 2 is a partially cutaway front view of the second embodiment. Here, 1 is a glass capsule container, 2 is a main ingredient component of an adhesive, 5 is a solid curing agent component, 6 is a processed portion that can be cut, and 7 is a sealing cap.

Example 1 The first example shown in FIG. 1 is a tubular glass tube having an outer diameter of 4 mm, an inner diameter of 3 mm, a length of 100 mm and a wall thickness of 0.5 mm, which is cut every 20 mm in the longitudinal direction by a diamond cutter on the outer circumference of the tube surface. Make thin cuts (scratches) at 4 points, fill the inside of the glass tube with unsaturated polyester resin (resin viscosity: 40 poise, 20 degrees C), which is the main component of the adhesive, and use solid particles of the solid curing agent. Benzene peroxide was attached to the outer surface of the glass tube with an adhesive to fabricate an adhesive capsule. Using this adhesive-containing capsule, an anchor was constructed with the following specifications.

The construction specifications of all anchors were smoothly implemented. The capsules used had a total length of 100 mm and were easily cut by hand at the position where the scratches were made in accordance with the perforation size to use, and no resin flowed out during cutting. Two capsules were used to construct the four anchors in the table above.

Embodiment 2 The second embodiment shown in FIG. 2 is 10 mm in diameter, 100 mm in length,
The outer peripheral part of the central tube surface of a tubular glass tube with a wall thickness of 0.6 mm is subjected to a narrowing process (internal diameter 5 mm) to reduce the tube diameter by high heat, and the recessed part of the narrowed part is strain-processed by easy cut to make glass. Unsaturated polyester resin (resin viscosity: 4
0 poise and 2000 poise, 20 degrees C) were filled, and granular peroxide benzene as a solid curing agent component was adhered and laid on the outer surface of the glass tube with an adhesive to prepare an adhesive capsule. Using this adhesive-containing capsule, an anchor was constructed with the following specifications.

The construction specifications of all anchors were smoothly implemented. As the specification capsule, a capsule with a total length of 100 mm was used by easily cutting it by hand according to the drilling size at the scratched position. The resin viscosity of the unsaturated polyester resin used is
In the case of 40 poise (20 degrees C), the inner diameter is 3 m in Example 1.
Since it was m, the resin did not flow out from the capsule at the time of cutting, but in Example 2, the resin flowed out from the capsule because the inner diameter was 5 mm. However, adding a thickener to a resin with a resin viscosity of 40 poises (20 degrees C) gives 2000 poises (20 degrees C).
When the degree was C), the resin did not flow out from the capsule at the time of cutting.

EFFECT OF THE INVENTION Since the multi-adhesive capsule for adhesive post-installed anchors according to the present invention is configured as described above, it is possible to apply manual force to one or several points in the longitudinal direction of the adhesive-containing capsule. The capsule container is fragile so that it can be easily cut, it can be folded into multiple capsules, and by matching the cutting dimensions, it is easy to select capsules on-site for various anchor drilling depths. Further, it has an effect that encapsulation of a short size of 2 to 3 cm, which has been difficult to manufacture in the past, can be performed by using a long capsule by folding it, and further, it leads to a decrease in manufacturing unit price.
