Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for processing a metal mesh for mortar wall type;
More specifically, the present invention relates to a method of processing a large-mesh metal mesh for mortar walls, such as so-called "lath", to substantially reduce the mesh to make it effective for spray mortaring and the like.

The metal mesh (lath) used when building mortar walls has various forms depending on the purpose, and the mesh size also varies, but in general, if the mesh is too small, the adhesion of the mortar will decrease. On the other hand, if it is too large, there are drawbacks such as excessive leakage of mortar through the mesh to the other side.

Furthermore, depending on the size of the mesh, various problems tend to occur in workability, rigidity, workability, etc. For example, when a metal mesh is used as a facing material for a panel, etc., and the surface is sprayed with mortar, the adhesion of mortar to the mesh itself, its rigidity as a facing material, or its workability during panel manufacturing may be affected. However, as mentioned above, there are advantages and disadvantages depending on the size of the mesh, and there was no good mesh on all sides. Additionally, metal nets for mortar walls are usually treated with anti-corrosion treatment before use, and this anti-rust treatment is generally done by immersing the metal net in a rust-preventing solution, then drying it after pulling it up. This is done by means of

The present invention has been made in view of the above-mentioned points, and after surface-treating the metal network described above with a rust-preventing liquid having adhesive properties, the rust-preventing liquid has adhesive properties on the surface of the metal network. A fibrous substance is attached to the surface of the metal net while the metal mesh is held, and the gaps between the meshes of the metal net are partially or completely covered with the fibrous substance. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the method of processing a metal mesh for mortar wall type according to the present invention will be described in detail based on its embodiments with reference to the drawings. First, the metal mesh body 1 is immersed in a rust preventive solution by a conventional method, and the rust preventive solution is applied to the surface of the mesh structure 1.

As this anti-corrosion liquid, one that has anti-rust power and has adhesive properties until it adheres to the surface of the net-like body 1 and dries is used, such as a solution of ethylene vinyl acetate resin, Radex, etc. Examples include a liquid mixture of emulsion and cement. Next, after immersing the metal mesh body 1 in a rust prevention liquid and pulling it up, while the rust prevention liquid has adhesive properties on the surface of the metal network body 1, the fibrous substance 2 is sprayed onto the surface using a gun. Attach and attach.

As the fibrous material 2, for example, steel, glass fiber, rock wool, etc. are used. As a result, the gaps 3 between the meshes of the metal mesh body 1 before treatment shown in FIG. As a result, the mesh of the net-like body 1 becomes substantially smaller.

The amount of adhered fibrous material 2 may be adjusted depending on the purpose. Incidentally, the means for surface treatment of the network body with the Vc anticorrosive solution of the present invention and the means for attaching the fibrous substance may be changed to other means as appropriate.

Moreover, the processing method of the present invention can be carried out without being restricted in any way by the form of the metal mesh. As described above, according to the processing method of the present invention, the mesh size of the metal mesh for Molnol wall type can be easily reduced as necessary, and moreover, the rust prevention treatment process of the metal mesh is utilized. Therefore, the desired purpose can be achieved without requiring any special steps other than simply attaching the fibrous material.

In addition, the metal mesh whose mesh size is substantially reduced by the processing method of the present invention is particularly effectively used as a lath for spraying mortar, and the fibrous material acts as an anchor for the mortar. It is possible to improve the adhesion of the mortar and prevent the mortar from leaking from the mesh of the mesh to the opposite side.

Specifically, as shown in FIG. 3, for example, a steel sheet having an internal space 12 formed by suitably bending and joining a pair of mesh metal plates (metal mesh bodies of the VC of the present invention) with a predetermined interval. A panel 10, a mortar layer 11 formed by spraying mortar on both outer surfaces of the steel panel 10 and solidifying it, and the internal space surrounded by the mortar layer 11 after the mortar layer 11 has solidified. If the net-like part of the building structure Vc consisting of the aerated concrete part 13 filled in the aerated concrete part 12 is processed by the processing method of the present invention, there is a risk that mortar will excessively enter the internal space 12 during spraying. In addition, the anchoring action of the fibrous material can improve the adhesion of the molarity.It should be noted that the state of adhesion of the fibrous material is omitted in Fig. 3.
