Since the metal expanded mesh 13 (or steel mesh) has a plurality of meshes 131 arranged at intervals, the cement slurry is easily lost during the pouring of the concrete 15 to affect the quality, and the metal of the pillars n and the metal expanded mesh 13 The smooth surface is not well bonded to the concrete 15, so cracks are easily generated at the joint. In order to solve these problems, the industry is trying to improve the loss of cement liquid 2 by changing the shape of the mesh ΐ3ι or by fitting the fiber cloth (not shown), but its effect is not satisfactory, and the metal expansion network is caused. 13 No:: Brightness can not see whether the slurry condition at the time of irrigation is good at any time: when the adjustment of 'reconstruction concrete 15 and metal expansion net (4) in different shell materials', so after the completion of grouting, in the outer wall mud At the time of the bottoming, the joint 1288164 is not easy. If the cement slurry is lost during grouting, it will affect the structural safety of the whole building, so it is necessary to improve. SUMMARY OF THE INVENTION Therefore, the first object of the present invention is to provide a changeable mud which can prevent the loss of cement slurry when grouting 5, and can closely combine concrete with metal expanded mesh and mud spray into a solid structural wall.

The combination of tightness and water resistance and breathability ensure quality. The invention can change the interface of the metal expansion mesh used for the mud. The construction method 1288164 comprises the following steps: (A) The operation of the net module is to fix a metal expansion net with several meshes on both outer sides of the plurality of columns. , the two metal expansion nets cooperate to define a grouting space; 5 (B) paint spraying operation: spraying the paint of the invention on the outer side of the net mold and forming a web film; (C) Heart concrete operation is to inject concrete into the grouting space; (D) Mud spray operation: the cement mortar is sprayed on the outer mesh surface of the two metal expanded mesh to form a wall surface. In addition, the present invention can change the construction method of the interface of the metal expanded mesh used for the mud, and can also include the following steps: (E) Metal expanded mesh spray coating operation: spraying the paint of the present invention into one of several meshes The metal mesh expands the outer mesh surface of the mesh, and forms a mesh film on the outer mesh surface; 15 (F) mesh module stands up: the two metal expanded meshes in which the mesh film is formed in step (E) are respectively fixed The two outer sides of the plurality of columns are assembled into a net mold, and the two metal expanded nets are combined to define a grouting space; (G) the concrete pouring operation is: pouring concrete into the grouting space; (H) mud spraying Pulping operation: a cement mortar is sprayed on the outer mesh surface of the two metal expanded mesh 20 to form a wall surface. Through the above steps, a solid structural wall in which concrete and metal expanded mesh and cement mortar are integrated into one body can be obtained, and has the characteristics of being convenient to be applied and improving construction efficiency. The metal expanded mesh interface finished product of the invention can be modified by spraying the spray coating of the invention of 1288164 on a metal expanded mesh. The metal expanded mesh interface finished product of the present invention can be obtained by spraying the spray coating of the present invention on a two-spaced metal expanded mesh of a mesh mold. The metal expanded mesh interface finished product of the present invention can be obtained by spraying the spray coating of the present invention on a metal expanded mesh, steel bar and column of a mesh mold. The above and other technical contents, features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments of the drawings. As shown in Figures 2 and 3, a preferred embodiment of the spray coating 2 of the present invention which can modify the metal expanded mesh interface used for the mud comprises: a water- or oil-based ratio of between 65% and 77% by composition. The resin adhesive 21, and the composition ratio of 20% to 30% of the strontium sand 22 is mixed as the main eyebrow material, 15 and a small amount of polypropylene fiber 23 is added in a composition ratio of 3% to 5%. The composition 20 is mixed and formulated. The aqueous or oily resin adhesive 21 may be: acrylic resin, EVA 'UtCethylene-vinyl acetate copolymer, ethylene-vinyl acetate copolymer), a mixture of acrylic resin and EVA resin, and acrylic tree 2 resin. Mixture with clay, a mixture of EVA resin and clay, a mixture of acrylic resin and EVA resin and clay. It is worth noting that the clay is best with high viscosity clay. As shown in Figs. 4 and 5, when the above-mentioned raw materials are blended in a certain proportion to the coating material 20 of the invention, it can be adhered to 1288164 by the granules of each of the granules of the present invention. The aqueous or oleoresin adhesive 21 and polypropylene fibers can be adhered to each of the granules. 23, after spraying the paint 2 onto a metal expanded mesh 30 by using a general spray air gun or a stone spray paint device (not shown), the paint 20 can be adhered to each metal expanded net 30, and The polypropylene fibers 23 are evenly spread over the outer mesh surface 31 and the inner mesh surface 32 of the metal expanded mesh 530. The characteristics and effects of the above raw materials are described later: The aqueous or oily resin adhesive 21 has good elasticity and ductility, good viscosity, and is difficult to be reduced and dissolved in water after drying, so that it is not sprayed after being sprayed. The water-repellent property, and the acid value of the acrylic resin and the EVA resin are between 7 and 8 and also have cement-friendly properties, so it is very suitable for use on the metal expanded mesh 30 of the mud work. In the preferred embodiment, the silica sand 22 is preferably white chalk sand, and the particle diameter of each white sandstone is 〇·〇5~〇·; [mm, the weight of the particle diameter can be used to help The uniformity of the coating material 20 during mixing, and the particle weight of the coating material 20 can also be used to uniformly carry out the polypropylene fiber 23 in the spraying operation, and the spraying operation can be carried out extremely smoothly, and the polypropylene fiber 23 can also be driven. Make it an excellent deployment. The polypropylene fiber 23 has a length of 12 to 19 mm and a fineness of less than 50 deniers, and has a density of 〇·9 g (0 9 g/cm 3 ) per cubic centimeter, thus being adhered to the aqueous or oily resin. The dispersibility in the agent 21 is good, and no ball formation is formed during the mixing, and at the same time, it has characteristics such as white light transmittance, good acid and alkali resistance, and zero water absorption. When the polypropylene fiber 23 is taken up by the sand 22 and is evenly covered on the outer mesh surface 31 and the inner mesh surface 32 of the metal expanded mesh 30, it can simultaneously extend through most of the mesh 33 of the metal expanded mesh 30 of 1288164. The three-dimensional fiber web is formed, and the outer mesh surface 31 and the inner mesh surface 32 which are originally smoothed by the metal expanded mesh 3 are transformed into a rough surface and a white transparent mesh film is formed (please refer to the physical photograph of the attached one). In this way, the bonding interface of the metal expanded mesh 3〇 and the poured concrete and the mud spray can be changed. § After the mesh film is formed on the metal expanded mesh 30, the cement slurry can be prevented from being lost when the concrete is poured, thereby ensuring the quality of the concrete. Because the concrete has been changed to the _ bonding interface of the metal expanded mesh and the mud spray, the bonding strength of the three can be effectively improved, and the combination of the three can be avoided due to thermal expansion and contraction. Moreover, since the polypropylene fiber 23 has light transmissivity, when the concrete is poured, it can be seen whether the slurry condition of the grouting is good or not, so that it can be appropriately adjusted at any time, and because the polypropylene fiber 23 is irregularly intersected. It has a gas permeable effect, so that in addition to no side pressure and pressure, the metal expanded mesh 3 and other building components (not shown) and the welded parts can be prevented from being rusted during grouting. It can further maintain the structural safety of the whole building. In summary, the present invention can change the interface of the metal expanded mesh used for the mud, and the surface spray coating 20 is composed of materials such as water-based or oil-based resin adhesives 21, such as Shixia 22 and polypropylene fiber 23. In order to achieve the purpose of the present invention, it is sufficient to promote the combination of the concrete with the metal expanded mesh 30 and the slurry for spraying, and to prevent the cement slurry from being lost when the concrete is poured, and to have multiple protective effects. As shown in FIGS. 6, 8, and 9, a preferred embodiment of the method for constructing the interface of the metal 1288164 expanded mesh of the present invention comprises the following steps: · In step 91, the number of vertical columns 4 is The two outer sides of the crucible are respectively fixed (can be locked or nailed or welded). The two metal expanded nets 30 with a plurality of meshes 33' define a grouting space between the two metal expanded nets 3(). In this way, the assembly work of a mesh module 6 can be completed (refer to the photo a of Annex 1). In step 92, the coating 2 of the present invention is directly sprayed on the outside of the net mold 60 to form a web film 2; further, the paint may be sprayed on the outer mesh surface of the metal expanded net 30. 31. Column 40 and steel bar (not shown, please refer to Figure 1). With the foregoing, it can be seen that the coating material 20 will be evenly covered on the outer mesh surface 31, and the polypropylene fiber 23 can extend through the meshes 33 into the inner mesh surface 32 to form a three-dimensional fiber web (please refer to the attached file). In the photo b), at this time, the bonding interface of the metal expanded mesh 30 with the concrete 7 and the slurry is changed. In step 93, concrete 7 is poured into the grouting space 5, and the cement slurry of the concrete can be prevented from flowing out by the mesh film 200, thereby ensuring the quality of the concrete. In step 94, cement mortar 8 is sprayed onto the outer mesh surface 31 of the metal expanded mesh 30 to form a wall surface, thus completing the mud spray 20 operation. By the above steps, since the paint mold 6 is directly smashed, and after the dry film is formed into the mesh film 200, 20 sprayed on the net can perform the concrete pouring operation and the mud spray operation, in practice It has the advantages and advantages of being convenient to apply and effectively improving construction efficiency. -11- 1288164 In addition, since the outer mesh surface 31 and the inner mesh surface 32 of the metal expanded mesh 30 have been changed from the original smooth metal surface to the raw sugar surface by the coating material 20, the metal expanded mesh 30 and the concrete have been relatively changed. 70 and the joint interface of the cement mortar 80 for spray coating, so that the joint strength of the three can be effectively improved to obtain a solid structural wall, and in addition, cracks can be effectively prevented at the joint of the three. As shown in Figures 7, 8, and 9, another preferred embodiment of the construction method of the present invention for changing the interface of the metal expanded mesh for use in mud comprises the following steps: In step 95, the coating 2 of the present invention is used. The crucible is sprayed on the outer mesh surface 31 of a metal expanded mesh 30 provided with a plurality of meshes 33, and a mesh film 2 is formed on the outer mesh surface 31. In step 96, the inner mesh surface 32 of the two metal expanded mesh 30 in which the mesh film 2 has been formed in step 95 is respectively placed on the outer sides of the plurality of columns 4 to be assembled into the mesh mold 6 The crucible space 50 is defined between the two metal expansion nets. In step 97, concrete 7 is poured into the grouting space 5; the concrete slurry 200 prevents the concrete slurry from flowing out, thereby ensuring the quality of the concrete 70. In step 98, the cement mortar 8 is applied to the outer mesh surface 31 of the metal expanded mesh 30 to form a wall surface, thereby completing the mud spray operation.
