Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of fixing a general mechanical anchor with an adhesive capsule. That is, it relates to a construction method that uses an adhesive capsule in combination with an impact type mechanical anchor.

[Conventional technology] Conventionally, impact type mechanical anchors have often been used as a means of attaching equipment, etc. to the concrete surface, but the fixation area of the anchor buried in the hole is only in the bulge at the tip. Therefore, displacement is likely to occur, and since there is a gap between the anchor body and the hole, it is unsuitable for use in areas with strong vibrations, leading to unexpected disasters. On the other hand, injection methods using mechanical anchors and adhesives have been used, but they are not easy to work with.

[Problems to be Solved by the Invention] As mentioned above, there is a need for a method of fixing mechanical anchors with adhesive that is easy to work with and has high strength. It was a point.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and its gist is to provide a construction method in which adhesive is used in combination with mechanical anchors for post-cast anchor bolts. In , the adhesive is a two-component self-setting binder in a container made of glass or plastic tubing that is easily ruptured.
It is an adhesive capsule that contains one component and one other component that forms a pattern on the outer circumferential surface of the container.The adhesive capsule is inserted into the perforation, and a general impact type mechanical anchor is struck from above. The adhesive capsule ruptures at the same time as the anchor body is inserted, expanded and fixed, and the inner and outer layer components come into contact, starting a hardening reaction, filling the gap between the hole and the anchor bolt, and hardening and fixing. This method involves fixing general mechanical anchors with adhesive capsules.

i [Example] The following will be described in detail with reference to Examples. FIG. 1 is a cross-sectional view of an adhesive capsule of the present invention. Here, l is a cylindrical container, 2 is a viscous liquid resin, and 3 is a hardening agent layer. Figures 2 to 4 show three main shapes of impact type mechanical anchors; Figure 2 is type A, Figure 3 is type B, and Figure 4 is type C. Further, FIG. 5 is an explanatory diagram showing a state in which an adhesive capsule is inserted into a perforation and a mechanical anchor is prepared, and FIG. 6 is an explanatory diagram showing a state in which a mechanical anchor is driven in with a hammer. Here, 4 is a hole, 5 is a mechanical anchor, and 6 is a hammer.

Mechanical anchors are fixed by expanding the anchor body when struck, and adhesive capsules contain one component of a two-component self-setting bonding agent in a glass or plastic tube container that easily ruptures when struck. This is a container in which a layer is formed using an adhesive and another component is placed on the outer circumferential surface of the container. The adhesive is suitably an unsaturated polyester resin or an epoxy resin, and the component forming the outer layer is suitably a solid curing agent component.

One embodiment of the adhesive capsule according to the present invention will be described with reference to FIG. The cylindrical container l is made of glass and has an outer diameter of 8I and a length of 30*. The cylindrical container 1 is filled with an unsaturated polyester resin, which is a viscous liquid resin 2, and sealed with a plastic cap.The outer circumferential surface of the glass cylindrical container 1 is filled with benzoyl peroxide using an acrylic adhesive. A layer of diluent is adhesively formed.

Next, the explanation will be given with reference to FIGS. 5 and 6. Using a drill, drill a hole 4 with an outer diameter of 10.5 mm and a depth of 30 mm, insert the adhesive capsule into the hole 4 from which chips have been removed, and attach a 3/8 mechanical anchor ( In a tensile test after curing, in which type A) 5 is hammered with a hammer 6 until the tip reaches the bottom of the hole, as shown in the table below, it was 1.700 kg compared to 1.100 kg for the regular type.
The results for types B and C are also shown in Table 0, where a high yield strength of g is obtained, and the relationship between the tensile force and the amount of deformation is shown for types A, B, and
When the C type is shown in the drawings, it is as shown in Figs. 7 to 9, and it is clear that the construction method according to the present invention is superior.

Test results [Effect of the invention] Since the present invention is configured as described above.

1 in the method of fixing mechanical anchors with adhesive
This method has the advantage that the anchor can be bonded using a method that is easy to work with and has high strength.

Claims (1)

[Claims] In the method of using adhesives in combination with mechanical anchors for post-cast anchor bolts, the adhesive is one component of a two-component self-setting binder contained in an easily ruptured container made of glass or plastic tubing, and the other component is It is an adhesive capsule made by forming a layer of ingredients on the outer circumferential surface of the container.
The adhesive capsule is inserted into the perforation, a general impact type mechanical anchor is inserted from above, the anchor body is expanded and fixed, and at the same time the adhesive capsule ruptures, and the content component and the outer layer component come into contact with each other. A method of fixing general mechanical anchors with adhesive capsules, which starts a curing reaction, fills the gap between the hole and the anchor bolt, and hardens and fixes.
