Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a material consisting of two liquids with different components such as a base agent and a curing agent that produce a bonding agent suitable for bonding various structures; An impregnating material such as a sponge that is impregnated with a bonding agent mixture of the above two liquids is stored separately in a synthetic resin storage bag, and when used, the two branches in the storage bag are mixed to form the impregnating material. The present invention relates to a storage bag for a structure bonding material that can be taken out after being impregnated.

[Conventional technology]

Conventionally, the bonding agent used to bond the rice segments of buildings and tunnels, for example, has generally been a mixture of two materials with different components, such as a main agent and a hardening agent. ) to (C), two liquids with different components, such as a base agent and a curing agent, are stored separately in a synthetic resin storage bag separated by an inner partition, and the inner partition is heated. A storage bag for two-wave mixing has been proposed in which the materials are temporarily fused together so that they can be peeled off by fusion, and when used, the temporary fused portion is peeled off to mix two liquid materials while allowing them to flow through each other.

However, with the above-mentioned storage bag, there are relatively few problems when the joint surface is horizontal, although the method involves applying or injecting a fluid adhesive, which is a mixture of two liquids such as a base agent and a hardening agent, to the joint. If the bonding surface is sloped or vertical, the bonding agent may run down or become uneven until it hardens, causing the bonding agent to break, and the bonding may not be performed reliably. There's a problem.

Therefore, as a countermeasure to these problems, today two liquids such as a base agent and a hardening agent are used to improve bonding properties not only when the bonding surfaces of structures are inclined or vertical, but also when the distance between the bonding surfaces is wide. Many impregnation methods have been proposed, in which an impregnating material such as a sponge is impregnated with a mixture of bonding agents, and the impregnated material is wrapped or inserted into the bonding surface of a structure for bonding.

[Problem to be solved by the invention]

However, as mentioned above, in the conventional impregnation method, 2
After mixing two liquids with different components contained in a liquid temperature storage bag, it is troublesome to impregnate an impregnating material such as a sponge, and there are problems such as staining hands and clothes during handling.

The present invention was proposed to address the above-mentioned problems, and includes a material consisting of two liquids, such as a base agent and a hardening agent, which produce a bonding agent suitable for bonding various structures; An impregnating material such as a sponge to be impregnated with the mixed bonding agent mixture is stored separately in a synthetic resin storage bag defined by a removable or peelable partition, and when used, it hardens with the main agent in the storage bag. After mixing two liquids with different components, such as a bonding agent, the impregnating material is impregnated with the bonding agent mixture and can be taken out, simplifying work and improving ease of handling. The purpose is to provide bags.

[Means to solve the problem]

To achieve this objective, the present invention provides two
The impregnating material, such as a sponge, to be impregnated with the bonding agent mixture obtained by mixing the material consisting of the above two liquids is defined by the first and second removable or peelable partitions. Each liquid is stored separately in a synthetic resin storage bag, and when used, the first partition is removed or peeled off to mix the two liquid materials, and the mixed liquid is mixed with the second partition by removing or peeling off. The present invention is characterized in that the impregnating material is impregnated with the impregnating material.

[For production]

Based on such a configuration, the storage bag for structure bonding material according to the present invention contains a material made of two liquids with different components, such as a base agent and a curing agent, which are measured according to a predetermined mixing ratio;
A removable or peelable first
．． Since each liquid was housed separately in a synthetic resin storage bag defined by the second partition, when used, the first partition separating the two liquids with different components such as the base resin and the curing agent must be removed or peeled off. By doing so, it becomes possible to circulate and mix the two liquids. After thorough mixing by hand kneading, remove or peel off the second partition between the impregnating material containing the sponge, etc., and allow the fluid binder mixture to soak into the impregnating material. It becomes possible to incorporate it. Therefore, by repeating the hand-kneading operation again, the fluid binder mixture is thoroughly soaked into the impregnating material, and then the storage bag is cut out and taken out, and wrapped or clamped around the desired joint. Structures are joined using the impregnation method.

Therefore, the material consisting of two liquids with different components such as the main agent and the hardening agent can be efficiently mixed before opening the storage bag, and the mixed liquid of the bonding agent can be taken out after soaking into the impregnating material. It is hygienic and does not stain hands or clothes, improving work efficiency.

In addition, since the impregnated material impregnated with the above-mentioned bonding agent can be wrapped or clamped around the joint, there is no possibility of the bonding agent flowing down or shifting until it hardens. Therefore, it is possible to perform bonding using a reliable impregnation method.

Therefore, by repeating the hand-kneading operation, the two liquids are mixed to produce a fluid binder mixture having a predetermined mixing ratio. Thereafter, the second partition part 5b is peeled off to communicate the inside of the chamber 6c containing the impregnating material 8, and the mixture of the bonding agent can be sufficiently penetrated into the impregnating material 8 by hand kneading operation again.

Next, as described above, before opening the storage bag 6, the storage bag B is opened.
After impregnating the impregnating material 8 with the mixture of bonding agents that has been sufficiently mixed in the container, a part of the storage bag 6 is cut out and taken out, and as shown in FIG. The joining operation is carried out by wrapping or clamping the impregnated material 8 around 12a and assembling it.

In this way, two different components of the base agent 7a and the curing agent 7b are used.
The work of mixing two liquids and impregnating the impregnating material 8 with the mixed liquid is efficiently carried out in one sealed bag before opening the storage bag 6, so the work can be done without getting your hands or clothes dirty. Efficiency can be improved.

FIGS. 4 and 5 show other embodiments of the partition portion of the storage bag 6 according to the present invention, which is formed by a long and narrow concave clip 15 made of plastic and a convex clip 16 fitted into the clip. The concave clip 15 and the convex clip 1B sandwich the storage bag e at a predetermined position from both sides, and the chambers 8a, 6b, and 6c for storing the base agent 7a, curing agent 7b, and impregnating material 8 are formed at both bottoms. be done.

In addition, the storage bag 6 for the bonding material according to the present invention has a first and a second storage bag.
Three chambers 8a, 8b are formed by the partitions 5a, 5b.

Although the case where both bottoms are formed at 6c has been described, the present invention is not limited to this, and it is also possible to configure a plurality of sets in a continuous band shape.

〔Effect of the invention〕
