Next, the action of the concrete repairing wire mesh of the present invention having the configuration as described above will be described.

First, the operation of the concrete repair wire mesh shown in FIGS. 2A to 2C will be described.

First, a method of forming the spacer 218 will be described. The spacer 218 is formed by cutting the body 212 of the thin plate at a 'C' and then vertically bending it. In addition, when the spacer 218 is formed as described above, since the through hole 216 is inevitably formed, the spacer 218 and the through hole 216 may be simultaneously formed by one process.

In addition, the spacers 218b illustrated in FIG. 2B are formed by cutting the body 212b in the opposite direction, respectively, and then vertically bending them in the opposite direction. As a result, the through hole 216 is formed.

Then, the concrete repair wire mesh 200 shown in Figure 2a is completed by elastically fastening a plurality of wire rope 220 to the fixed hook 214 of the thin plate 210.

When the wire mesh 200 completed as described above is positioned in the concrete structure S, the spacer 218 contacts the concrete structure S, and thus a space of a predetermined interval is formed between the wire mesh 200 and the concrete structure S. This is formed, by pouring concrete into this space, the wire mesh 200 and the concrete structure (S) is more firmly integrated.

Even when the wire mesh is formed by using the thin plate according to FIG. 2B or 2C, the detailed description thereof will be omitted since the same operation as that in FIG. 2A.

The following describes the operation of the concrete repair wire mesh shown in FIGS. 3A to 3F.

3a to 3f is a wire mesh for repairing the structure, a fixed hook is a pair configuration, the fixed hook 314 shown in Figs. 3a and 3b is a pair of the configuration in the same direction cut When the wire rope 220 is fixed to the pair of fixed hooks 314 by elastically hanging and fixed at the same time, the wire rope 220 is more firmly fastened with the thin plate 310 so that the load of the poured concrete is large. It is possible to firmly fix the poured concrete.

The fixing hooks 314c, 314c ', 314d, 314d', 314e, and 314e 'shown in FIGS. 3C to 3E are pairs of fixing hooks in different directions, whether the wire mesh faces upward or downward. Regardless of the direction, the wire rope 220 can be fastened more firmly, so that even if the load of the poured concrete is large, the poured concrete can be more firmly fixed.

Next, the operation of the concrete repair wire mesh shown in FIGS. 4A to 4D will be described.

The concrete repair wire mesh shown in FIGS. 4A to 4D uses a steel bar 420 without using a wire rope, and the steel bar 420 is elastically fitted to the leaf spring 414 so that the steel bar can be used. It is made by being fixed to the fastening thin plate 410.

In the case of the steel bar fastening thin plate 410c constituting the wire mesh shown in FIG. 4C, since the plate springs 414c are formed in pairs, the steel bars 420 can be more firmly fixed, and also in FIG. 4D. In the case of the steel bar fastening thin plate 410d constituting the illustrated wire mesh, it is composed of a pair of leaf springs 414d whose cutting directions are opposite to each other, so that the steel bar 420 can be more firmly fixed. .

Finally, as shown in Figures 5a to 7b, it is possible to secure the wire mesh to the concrete structure (S) using the anchor pin set (500, 600, 700), and thus wire mesh to the concrete structure (S) After fixing it in the concrete, the concrete is poured to perform the repair work.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.

Concrete repair wire mesh of the present invention having the configuration and action as described above has the following effects.

First, by constructing a pair of fixed hooks for elastically hanging the wire rope, there is an effect that can be more firmly fastened.

Second, by providing a spacer in the thin plate to form a predetermined space between the wire mesh and the concrete structure, and the concrete is poured into the predetermined space, there is an effect that the concrete poured with the wire mesh is more solid.

Third, instead of the conventional wire rope, the steel bar is configured as a wire mesh and provided with a leaf spring for fixing the steel bar, thereby simplifying the work time for constructing the wire mesh and installing the wire mesh at the same time. It works.
