Description

Construction method for outer wall insulation finishing material of building using track structure and its structure {THE OUTER WALL INSULATION MATERIALS AND THE STRUCTURE}

 The present invention relates to a method for constructing an outer wall insulation finishing material of a building using a track structure, and more particularly, after fixing a reinforced PVC track structure to an outer wall of a building, EPS (Expandable Polystyrene) of the insulating material formed with fastening grooves in all directions: By inserting and fixing the foamed polystyrene) board, the installation of the EPS board is easy and convenient, and the fixing force is improved by preventing bending and dropping of the EPS board due to shrinkage and expansion of the acrylic cement adhesive mortar for attachment. It is related to the construction method and structure of the outer wall insulation finishing material of the building using a track structure to increase the antifouling property by coating a fluorine acrylic transparent coating treatment as well as a beautiful appearance by the integral finish without a cut surface.

In general, it is inevitable to install a heat insulating material on the outer wall surface of various buildings to prevent heat loss, and the heat insulating material is attached to the outer wall surface by curing a board made of a certain size panel type as adhesive mortar of resin, Various types of finishes are also attached to the surface with adhesive mortar to finish the construction.

The board of the thermal insulation material is to be constructed so that the thermal insulation wall is formed on the outer wall of the old building as well as the various buildings that are stretched, and in recent years, the thermal insulation material is mostly attached to the adhesive mortar or the like mixed with acrylic using an EPS board, After reinforcement with glass fiber mesh, various finishing materials are applied by coating, spraying, spraying, etc., and the construction methods such as applying artificial stone, natural stone, etc. are very common.

In other cases, wet and dry methods may be mixed, and cement boards and magnesium boards may be attached to EPS boards, and glass fiber mesh and various finishing materials may be paneled in advance to form C-shaped steel structures or anchor bolts. As a method of physically attaching the panel to the outer wall of the building by using angles and the like, a cement adhesive mortar is additionally added thereto.

Looking at the structure that is most widely used in this conventional construction method as an example, which is a plurality of cement mortar (2) for cement bonding to the concrete outer wall (1) of the building as shown in Figure 1 of the accompanying drawings Partial coating is applied to cure the heat insulating material 3 made of EPS board or the like, and the mesh 5 made of glass fiber material is attached to the outer surface of the heat insulating material 3 by applying adhesive mortar 4 for plastering as a whole. Curing, and then to the outer surface of the mesh (5) to finally finish the curing 6 attached.

However, the conventional outer wall insulation construction structure as described above is that the heat insulating material 3 and the finishing material 6 is attached by adhesive mortar, the risk of falling off from the outer wall due to the increase in the load of the EPS board itself as the heat insulating material (3). There was a problem that is always exposed, and furthermore, when the construction is used by mixing and mixing the adhesive mortar (2) for cement bonding in the field, there is a problem that a lot of time and economic loss in operation occurs.

In addition, as the attachment process by the adhesive mortar (2) (4) is cured according to natural conditions, that is, the heat insulating material and the finishing material adhered by the adhesive mortar are cured for 1 to 2 days after application according to the climate during construction. Since the time required is inevitably required, there was a problem in that the construction period is considerably longer depending on the climatic conditions, and quality problems may occur depending on the temperature of rain or curing conditions after the work.

Particularly, in the application of the finishing material 6, there is a problem that it is difficult to equalize the quality due to the deviation according to the skill of the operator, the quality is poor, and the partial application of the adhesive mortar 2 for adhesion to the concrete outer wall 1 is also applied. In the process of attaching the heat insulating material (3), the remaining material of the heat insulating material is generated a lot, there was also a problem that the environmental pollution problem is seriously raised as a result of the treatment.
