[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler for injecting a filler for filling cracks and floats generated in a concrete building or the like, and more particularly, to a filler attached to the tip of the filler and building or the like. The present invention relates to a washer for injecting a crack filler into a crack or a gap while mixing a main agent and a curing agent applied to the seal portion.

[0002]

2. Description of the Related Art Concrete is excellent in durability and relatively inexpensive, so that it is widely used not only in high-rise buildings but also in ordinary houses. However, on the other hand, cracks and floating easily occur on concrete floors, walls and ceilings. , Durability is reduced.

When such cracks occur, it is widely practiced to fill the cracks with an epoxy resin. When the width of the crack is large, a method of filling the epoxy resin with a high-pressure pump is adopted.However, when the width of the crack or the gap due to floating is small, the air escape path is blocked by the filler, so injection is required. This makes it difficult to completely fill the place where cracks or the like occur. Therefore, a low-pressure injection method of filling the epoxy resin with a low pressure and a constant pressure has been conventionally proposed.
In this low-pressure injection method, a sealant is applied in advance to a portion where a crack or the like has occurred and sealed, and then an injection washer is attached at a predetermined interval at a location such as a crack and the filler is gradually removed from the injection washer. Since the repulsion pressure at the time of injection is lower than that of the high-pressure injection method, it can be injected even into fine cracks and the like, and secondary deterioration such as promoting floating due to the injection pressure of the filler occurs. There is an advantage that the injection can be performed without any problem.

[0004] As a filling tool for carrying out this low-pressure injection method, a filler made by putting a filler into a bag made of an elastic material such as rubber and injecting the filler with a restoring force of the elastic material is used. Injecting the filler in the injector using the air pressure compressed in the tank, or injecting the plunger of a syringe-type injector in which the filler is filled, by applying air pressure, spring pressure or extension from the compressor There is one that is gradually moved by the restoring force of the rubber.

[0005]

On the other hand, if the filler is an epoxy resin, and if the two components are a main component and a curing agent, the two components are mixed at the site to form an apparent one-component type, and then the above-described components are used. Filling tools are filled and injected. For this reason, since the filler hardens in the filler, there is a disadvantage that a large amount of the filler cannot be filled in the filler. For this reason, a large amount of small filling tools are required, which not only requires much work but also does not allow long-time injection, and does not allow sufficient injection into the deep part of the crack. Furthermore, since the filler cannot be injected in advance, the main agent and the curing agent must be mixed on site and filled into the filler, which requires a complicated procedure.

Accordingly, an object of the present invention is to provide a washer for injecting a crack filler in which the main agent and the curing agent can be separately prepared and the two components can be injected while mixing for the first time at the time of filling. is there.

[0007]

The washer for injecting the crack filler of the present invention has independent inlets for the main agent and the hardener,
And a first mixing section having a built-in dividing member for making the main agent and the hardening agent from these inlets into a small stream, and having a split section for mixing the trickled main agent and the hardening agent, and communicating with the mixing section of the split section. A mixing member for further mixing the main agent and the curing agent mixed therein, and a second member having a discharge hole formed at the bottom thereof.
And a mixing section.

The washer for injecting the crack filler according to the present invention is also constituted by a plurality of baffle members provided with a mixing member at intervals, and each of the baffle plate members has a discharge hole for mixing. The discharge holes are formed and arranged so that their positions are different from the discharge holes of the adjacent baffle plate members, or a large number of spherical bodies are put in the second mixing section so as to form at least a plurality of layers. It is characterized by comprising.

[0009]

When repairing a crack, a seal is provided on the crack at an appropriate interval in the same manner as in the prior art, and the injection washer is attached to the seal. A filler containing a main agent and a filler containing a curing agent are respectively attached to the two connection ports. The main agent and the curing agent enter the dividing section from the respective inlets of the first mixing section, and are mixed only after being made into a fine stream by the dividing member. The base material and the curing agent mixed to some extent enter the second mixing section, are further mixed by the mixing member, and are injected into the crack as a filler in which the base material and the curing agent are completely mixed through the discharge hole at the bottom. . As described above, the main agent of the filler and the curing agent may be prepared separately, and the two liquids do not contact and harden in the filler, so that the pot life can be greatly increased, and the filler can be used. Can also be increased in size, so that the total number of fillers can be reduced. The filler can also be used repeatedly.

When the mixing member is constituted by providing a plurality of baffle members having holes arranged at intervals in the axial direction, the liquid flowing out from the discharge hole at the bottom of each room is not affected by the obstruction thereunder. Due to the difference in the positions of the holes in the plate member, mixing is first repeated between the upper and lower baffle plate members, and then mixed again between the baffle plate member and the lower baffle plate member. While being pushed out from the outlet.

Further, if the mixing member is also composed of a large number of spherical bodies inserted so as to form a plurality of layers, the main agent and the curing agent entered from the two connection ports travel along the surface of the spherical body in various directions. At this time, the main agent and the curing agent can be mixed.
