As shown in Figure 1, the conventional construction of the outer wall surface is a step of attaching and curing the heat insulating material 120 by partially applying a resin mortar 110 for adhesion to the concrete outer wall 100, on the outer surface of the heat insulating material 120 Plastering resin mortar 130 for the entire application process to attach the mesh 140 to cure, the process of inserting the joint to form a joint on the outer surface of the mesh 140, the joint 160 between the joint and the joint It is made through the process of curing by applying a thickness of.

However, in the conventional exterior wall finishing process, the resin mortar coating and finishing material coating process has a high risk of curing due to natural conditions, and the resin mortar and finishing material require curing time of about 1 to 2 days after application according to the climate during construction. Depending on the climatic conditions, the construction period is prolonged or quality problems occur depending on the temperature of the rain or curing conditions after the work.

In the application of the finishing material 160, there is a problem that the quality is difficult to equalize and the quality is lowered due to the deviation depending on the degree of function of the operator.

In particular, in the process of arranging and attaching the heat insulating material 120 by partially applying the resin mortar 110 for adhesion to the concrete outer wall 100, a large amount of residual material of the heat insulating material is generated, thereby causing a serious environmental pollution problem. It is true.

Therefore, there is a demand for a method for overcoming an unreasonable point of the method for finishing the outer wall insulation and finishing the conventional construction and shortening the construction period in the field, and for reducing environmental pollution.

The present invention has been made in view of the above problems, the object of the present invention is to apply a finish on the mesh surface attached to the plastering mortar mortar to the insulation material to make a panel-like ready-made product attached to the concrete outer wall surface with adhesive resin mortar The completion of the finishing process by grooving provides a way to shorten the construction period without being affected by the number of processes and natural curing conditions on site.

Another object of the present invention is to apply a portion of the adhesive resin mortar 110 to the concrete outer wall 100 to arrange and attach the heat insulating material 120, a large number of residual materials of the heat insulating material is generated, the problem of handling the resin mortar and the container container In a situation where environmental problems caused by the problem are seriously emerging. Since the environmental pollution can be reduced and the demand for recycling is increasing, it is to provide a method to reduce the environmental pollution problem and to reduce the construction cost due to the shortening of the construction period.

According to one aspect of the present invention for achieving the above object, the step of preparing to bond the heat insulating material and the heat insulating material on the back surface, the step of preparing to attach the mesh mortar mortar to a predetermined thickness on the outer surface of the heat insulating material, the A process of preparing a coating material with a predetermined thickness on an outer surface to which a mesh is attached by using a plastic mortar, and a step of forming a joint between the finishing materials by grooving the surface coated with the finishing material. Exterior wall insulation finishing method is provided.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

FIG. 4 is a plan view illustrating a range in which a mesh is attached to a plaster resin mortar at the place shown in FIG. 3.

5 is a plan view showing a range of applying the finish to the surface shown in FIG.

FIG. 6 is manufactured in a ready-made form by making a groove dividing into a predetermined size and depth on the surface shown in FIG. 5.

7 is a panel-type construction three-dimensional view by a building outer wall insulation finishing construction method according to the present invention.

Referring to Figure 1 by using a conventional construction method, after attaching the heat insulating material 120 using the adhesive resin mortar 110 to the concrete outer wall 100, curing the adhesive resin mortar 110 for about one day and the heat insulating material 120 When the attachment is completed, apply plastering mortar 140 to the outer surface of the heat insulating material 120 in a thickness of 1-1.5 mm (preferably 1.5 mm), and then attach the mesh 130 to the surface and rub it with a plastering knife as if plastering. After curing, the joint is placed on the surface, and the process is completed by applying and curing the joint between joints having a joint height of about 2 mm after curing.

Referring to Figure 2, as a process to be made of ready-made. It is related to the process of preparing so that a heat insulating material and a heat insulating material can be firmly bonded to the back surface of a heat insulating material [FIG. 3], and the range which attaches a mesh to a predetermined thickness with a mortar resin mortar on the outer surface of the heat insulating material [FIG. 4]. Apply finishing materials to a predetermined thickness on the outer surface to which the mesh is attached [Fig. 5]. Curing the applied finish surface is grooved to make joints between the finishing materials. The finishing process is completed just by attaching with an adhesive resin mortar [Fig. 2].

According to the present invention, since it is manufactured as a ready-made product at a certain place, high-quality construction is possible, and the construction period can be considerably shortened by constructing it on site with a product manufactured in advance, and the quantity of construction waste generated during construction is considerably reduced. In addition, the environmental pollution problem can be significantly reduced by recycling the remaining materials generated during the manufacture of ready-made products.

According to the present invention, the adhesive resin mortar 49 should have a higher viscosity than the usual resin mortar (the viscosity of the resin mortar used for conventional plastering is 100,000 to 120,000 cps, whereas the viscosity of the resin mortar of the present invention 0-160,000 cps), curing time should be shorter than usual.

To this end, the plastering mortar 40 of the present invention is produced in the component ratios shown in Table 1 and Table 2.

TABLE 1

TABLE 2

The plaster mortar 40 of the present invention is produced by mixing the mixture of Table 1 and the mixture of Table 2 with a mixed hand mixer in a ratio of 1: 1 to 1: 1.5 (preferably 1: 1).

In the present invention, since the finishing material integrated mesh 40 must be fixed to the resin mortar layer by pressing, it requires a shorter curing time than usual, so 3-7 parts by weight of alumina cement having good roughness (preferably 5 parts by weight) is used. 93 to 97 parts by weight of white cement was mixed and used. If the alumina cement is less than 3 parts by weight, the curing time is long, and if the alumina cement is greater than 7 parts by weight, roughness and strength are improved, but there is a problem in that the unit cost is greatly increased.

The silica sand of Table 1 is for improving volume and compressive strength, and it is preferable to mix | blend 40-60 weight part. Here, when the silica sand content is 40 parts by weight or less, tensile strength, abdominal strength, adhesive strength, and compressive strength are improved, but the unit price is increased. When the silica sand content is more than 60 parts by weight, the tensile strength, abdominal strength, adhesive strength, compressive strength, etc. are lowered, and thus the desired strength is achieved. You won't get it.

According to the present invention, since the resin mortar is cured in a short time, there is a possibility that cracks may occur due to different curing rates of the resin mortars inside and outside, so that cracks are prevented by adding 0.1 to 0.3 parts by weight of acrylic fibers. When the acrylic fiber is added less than 0.1 part by weight, a lot of cracks are generated, and when the acrylic fiber is added more than 0.3 part by weight, there is a problem in that the cost is increased compared with no difference in effect.
