Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an adhesive-based post-installed anchor that fixes the anchor bolt in the buried hole by inserting the anchor bolt into the hole and embedding the anchor bolt from above. This invention relates to multiple adhesive capsules.

[Conventional technology] Conventionally, when attaching a post-installed anchor to a structure such as reinforced concrete, a drilling machine of an electric tool is used to drill a hole in the concrete body, and after cleaning the inside of the hole, an adhesive is inserted into the hole and the anchor bolt is attached. There are two methods: one method is to attach anchor bolts, and the other method is to mechanically attach anchor bolts using metal expansion anchors.

There are two types of adhesive-based post-installation anchors: capsule-type and injection-type anchors.The capsule-type, which is used for boat fishing, is a container in which the main component of the adhesive and the hardening agent component are placed in a cylindrical glass tube or plastic thin-film tube container. Some are known to be housed separately.

[Problems to be solved by the invention] In adhesive-based post-installed anchors using capsules containing adhesive, one or more capsules are inserted into the hole in which the anchor bolt will be buried, and the anchor bolt is inserted from above. By rotating and inserting the anchor bolt, the adhesive components are stirred and mixed and the adhesive can be hardened and fixed, but a long capsule or a short capsule that matches the depth of the anchor bolt is required.

However, it is uneconomical to prepare capsules of many different lengths for anchor bolts of the same diameter, and improvements are desired.

In addition, conventional adhesive-filled capsules have a base ingredient, a curing agent component, or an aggregate component sealed in the capsule using a double tube system.For example, as in the conventional example shown in Fig. 3, In a tubular glass tube, which is a capsule container l, there is an adhesive-filled capsule containing a base component 2, an aggregate component 3, and a curing agent component 5 housed in a thin tubular glass tube 4. Since each is sealed using the two-pipe system, the capsules are finely processed, for example, 5 cm in length.
It is very difficult to manufacture capsules with dimensions as small as m or less, and it is desired to make capsules shorter and smaller.

The present invention solves the above-mentioned problems, and by applying breakable processing to one or several places in the longitudinal direction of the adhesive-filled capsule so that the capsule container can be easily cut by hand force, the capsule can be folded into multiple pieces. It can be used as a book capsule, and by matching the cut dimensions, it is easy to select capsules for various anchor perforation sources on site.

In addition, it is now possible to create capsules with short dimensions of 2 to 3 cm, which were difficult to manufacture in the past, by breaking long capsules into short lengths.Furthermore, it is possible to make capsules with short dimensions of 2 to 3 cm, which was difficult to manufacture in the past, by breaking long capsules into short lengths. The purpose is to provide

[Means for Solving the Problems] In order to solve the problems listed in item L and achieve the purpose of the invention, the multiple adhesive capsule for post-installed adhesive anchors according to the present invention is constructed as follows. Features. In other words, an adhesive-filled capsule used for a post-installed anchor that secures an anchor bolt to a buried hole is processed so that the capsule can be easily cut at l or more locations in the longitudinal direction of the capsule. The main component of the capsule is housed in a capsule, and the curing agent component is attached to the outer periphery of the capsule container.

The multiple adhesive capsule for an adhesive-based post-installation anchor according to the present invention relates to an adhesive-filled capsule used for an adhesive-based post-installation anchor for fixing an anchor bolt in a buried hole.

The capsule container is processed so that it can be easily cut at one or more locations in the longitudinal direction of the capsule container. It is attached to.

Here, processing that allows the capsule container to be easily cut includes, for example, flaw processing, strain processing, drawing processing, etc. Flaw processing refers to processing in which a thin cut is made with a diamond cutter on the outer periphery of the tube surface, and It refers to the process of treating the surface of the container with a hydrogen acid solution, etc., and applying a coating. Strain processing refers to the process of treating the surface of the container with a hydrogen acid solution or the like.
Processing that creates strong tensile stress in the printed part of glass paint, causing distortion in the container, or drawing processing on glass tubes, which causes distortion in the container. Examples include glass paint and the like.

In addition, being able to cut the capsule container mainly means that it can be cut by folding it by hand, but it may also be possible to cut it using other files, knives, scissors, etc. However, since it is designed so that it can be divided into several parts for use, it can be said to be a multiple type.

As the adhesive, an unsaturated polyester resin, an epoxy acrylate resin, an acrylic resin, etc. using a thermosetting resin organic peroxide as a curing initiator can be used.

[Example] DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below using embodiments shown in the drawings.

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, ■ indicates a capsule container, 2 indicates a main component of the adhesive, 5 indicates a curing agent component, 6 indicates a cuttable portion, and 7 indicates a sealing cap.

Example 1 The first example shown in FIG. 1 is a tubular glass tube with an outer diameter of 4III11, an inner diameter of 3 mm, a length of 100 mm, and a wall thickness of 0.5 mm. Diamonds are placed on the outer circumference of the tube surface every 2 m. A cutter is used to make thin cuts (scratches) at four locations in the longitudinal direction, and the inside of the glass tube is filled with unsaturated polyester resin (resin viscosity: 40 voids, 20°C), which is the main component of the adhesive, and the curing agent component is An adhesive capsule was prepared by adhering granular benzene peroxide to the outer surface of a glass tube using an adhesive. An anchor was constructed using this adhesive capsule with the following specifications.

All anchor construction specifications were implemented smoothly. The capsule used was one that had a total length of 100 mm and was easily cut by hand according to the perforation size at the scratched position.No resin leaked out during cutting. Two wooden capsules were used to construct the four wooden anchors shown in the table above.

Example 2 The second example shown in FIG. 2 has a diameter of 10 layers and a length of 1
The outer periphery of the center tube surface of a tubular glass tube with a diameter of 0.00mm and a wall thickness of 0.8+am is subjected to drawing processing (inner diameter 5am) to reduce the tube diameter using high heat, and the concave part of the drawing part is further strained by easy cutting. unsaturated polyester resin, which is the main component of the adhesive with different viscosities (resin viscosity: 40 voids and 2000 voids), is applied inside the glass tube.
20° C.), and granular benzene peroxide, which is a curing agent component, was adhered to the outer surface of the glass tube with an adhesive to prepare an adhesive capsule. An anchor was constructed using this adhesive capsule with the following specifications.

All anchor construction specifications were implemented smoothly. Specification Capsules with a total length of 1001 cm were easily cut by hand to match the perforation size at the location where the scratches were processed. When the resin viscosity of the unsaturated polyester resin used was 40 voids (20 degrees Celsius), in Example 1, the inner diameter was 3IIm, so the resin did not flow out of the capsule during cutting, but in Example 2, the resin did not flow out from the capsule during cutting. Since the inner diameter was 5 IIm, the resin flowed out of the capsule. However, when a thickener was added to a resin having a resin viscosity of 40 poise (20 degrees C) to make it 2000 poise (20 degrees C), the resin did not flow out from the capsule during cutting.

(Effects of the Invention) Since the multiple adhesive capsule for adhesive post-installation anchors according to the present invention is configured as described above, it is possible to apply manual force to one or several locations in the longitudinal direction of the adhesive-containing capsule. The capsule container has been processed to be breakable so that it can be easily cut, and the capsule can be folded and used as multiple capsules.By matching the cutting dimensions, it is easy to select capsules for various anchor drilling depths on site. In addition, it is possible to make capsules with short dimensions of 2 to 3 cm, which have been difficult to manufacture in the past, by breaking long capsules into short lengths, and furthermore, it has the effect of lowering the manufacturing cost.
