Description

[Technical Field]

[0001] This invention is a construction method that is primarily intended for external insulation work on concrete buildings. It involves partially processing standard-shaped foam insulation material that is placed on the exterior building frame surface, or combining insulation materials of different shapes, to create a ventilated insulation material, allowing condensation that occurs inside the insulation material and water vapor that is generated to be discharged into the ventilation space, and by directly applying a lightweight finishing material to the insulation material, it is possible to omit the installation of base materials that were previously installed on top of the insulation material, reduce the total weight required for base work and finishing work, and achieve a shortened construction period and a significant reduction in construction costs. [Background technology]

[0002] In conventional external insulation construction methods, foam insulation is attached to the exterior surface of a concrete frame with adhesive or metal fittings, a base material is attached on top of the insulation, and building materials for exterior wall finishing or base building materials for finishing work are attached to this base material. Even when tiles are used as a finishing touch, they are usually applied to this attached base building material, and even when light finishes such as plaster walls or paint are applied, they are usually applied to this attached base building material.

[0003] Finishing building materials are building materials with a finish applied to their surface, which is then attached to a base material to complete the project. Base building materials are building materials that do not have a finished surface, and are intended for tiling, plastering, or painting after the installation. Base materials are generally made of steel, resin, or wood and are attached to secure these finishing and base building materials.

[0004] When attaching the base material to secure the building materials on top of the insulation, the base material is attached evenly at regular intervals in the vertical or horizontal direction relative to the insulation surface, so there is a certain distance between the base materials, and by attaching the building materials to the base material, a space equal to the thickness of the base material is created between the outer surface of the insulation and the back surface of the building material. This space is also very important for ventilation to allow moisture to escape from the insulation, so assembling the base material was also necessary in terms of ventilation.

[0005] When external insulation finishing work is carried out without installing a ventilation layer, for example, when the insulation material and building materials are directly bonded together without any gaps, or when mortar or tile is applied directly on top of the insulation material, condensation occurs inside the insulation material and the moisture has nowhere to go, causing problems such as swelling of the exterior wall finishing material and peeling of the building material due to moisture absorption. Furthermore, condensation that occurs inside the insulation material can affect the inside of the building and cause indoor condensation. In order to prevent these factors, installing a ventilation layer is essential when using external insulation construction methods.

[0006] However, this base material is made of expensive materials such as steel and resin, and in order to secure it, anchor bolts must reach the concrete base and be fastened one by one, which is an extremely difficult task, resulting in a significant construction time and cost. Furthermore, the anchor bolts used to secure this base material break through the external insulation to reach the concrete base, which causes insulation loss in those areas and can lead to localized internal condensation. This is because the finishing materials are heavy, so the base material also had to be secured with sturdy anchor bolts. Summary of the Invention [Problem to be solved by the invention]

[0007] The problem to be solved was the conventional external insulation construction method, in which a base material is attached to the exterior insulation material of a building, and then exterior wall finishing materials or base material are attached to this.This construction method takes a long time to complete and is expensive, so external insulation construction has not yet become widespread.Therefore, the challenge was how to completely eliminate the installation work of this base material and building material. [Means for solving the problem]

[0008] The present invention is a construction method in which a ventilated insulation material, which is made up of only insulation material and has a ventilation layer, is installed on the insulation material body that is attached to the outside of a building, and lightweight finishing work such as plaster wall material is then directly applied to the insulation material to complete the construction.Two solutions, (1) and (2), are proposed here.

[0009] Method (1) creates insulation by creating multiple slits of a certain size at equal intervals along the long or short side of the insulation. The slits run continuously from one end of the insulation to the other, creating a ventilated insulation with multiple cavities of the same shape at equal intervals.

[0010] During construction, the slit insulation is attached to the outside of the building with adhesive, but the slit cavity runs continuously and uninterrupted from the bottom to the top of the surface where the insulation is being installed. If the width of the slits in the insulation is relatively narrow, for example within 10 mm, fiberglass mesh tape is applied to the surface of the slits to seal the space with the mesh tape, preventing the plaster wall material to be finished later from penetrating into the slits, maintaining the space in the slits and leaving a continuous ventilation space, and then a combination of elastic plaster wall material and fiberglass mesh is installed on top to finish the work.

[0011] You may be wondering whether the hollow area at the width of the slit can be maintained strong with just the mesh tape and plaster wall material, but in fact, a small amount of the plaster wall material will protrude into the slit through the mesh of the mesh tape. This protrusion serves to reinforce the width of the space at the slit, making it as strong as the other surfaces. Also, because the protrusion is small, it does not obstruct the space.

[0012] Once the wall finish is complete, it will be strong enough that an average man can throw a softball at it with great force without it denting. Simply applying foam insulation and plaster to the wall will not provide sufficient strength, but by combining it with a strong, coarse-grained fiberglass mesh, the strength is increased several times over. However, if necessary, the exterior walls on the first floor can be constructed with other strong building materials glued to the insulation and mesh base, but this finish is sufficient for the second floor and above.

[0013] Another method for producing ventilated insulation (2), other than the method for producing ventilated insulation with slits created by cutting insulation material as described in 0009, is to use insulation material other than the insulation material used in the main body, and create ventilation components (here called insulation furring strips) that are cut to a specific shape in advance.This can then be attached to the main body of insulation at specific intervals with adhesive to produce ventilated insulation with a shape similar to the slit insulation produced in the previous section 0009.

[0014] The dimensions of the width and depth of the slits are not limited and should be determined according to the situation. However, a certain amount of space is required for ventilation, and if the width or depth of the slits is small, the space is also small, so the spacing between the slits should be narrowed to increase the ventilation space. Also, if the width of the slit space is to be increased, it is appropriate to use a manufacturing method that involves attaching insulation furring strips rather than slits made by cutting notches in the insulation, and to increase the spacing between the insulation furring strips.

[0015] The manufacturing method involves attaching multiple insulation furring strips at regular intervals along the long or short side of the insulation body, from one end to the other, with adhesive, and then layering another standard plate-shaped insulation material on top of the insulation furring strips to form a ventilated insulation. As a result, the insulation furring strips are sandwiched between the main insulation and the other insulation material to be attached, creating a ventilated space between the sandwiched base materials, which in this case can be made wider.

[0016] The ventilated insulation produced in this way does not have slits on the surface, making the application of mesh tape unnecessary. In this case, the finishing is done by applying plaster directly to the ventilated insulation, laying a fiberglass mesh on top of it, pressing it down with a trowel so that it is embedded in the first plaster, and then applying another plaster on top to complete the finish.

[0017] Ideally, this ventilated insulation would be manufactured in a factory in the same shape and then delivered to the site as a finished product. However, it is also possible to process it into the same shape on-site and install it, or there are methods that combine both. For example, groove-shaped slits can be cut into the insulation either in the factory or on-site. It is also possible to process the insulation furring strips in the factory and then attach and install them on-site.

[0018] The finish applied to the ventilated insulation material produced by method (2) does not have any slits on the surface, so it can be applied by adhesive to any lightweight finishing material, not just plaster wall materials, even plate-shaped materials.Lightweight tiles and spray-on painting work are also possible by performing surface treatment on the underlying ventilated insulation material. [Effects of the Invention]

[0019] The ventilation finish construction method for external insulation of the present invention provides a ventilation space in the insulation installed on the outside of a building, so even if the entire exterior of the insulation is covered with a finishing material, the ventilation layer solves the problem of internal condensation in the insulation. Moreover, since the base materials are all composed of insulation and adhesive, and the finishing materials are only glass fiber mesh and elastic plaster wall material, the total weight of the insulation, base material, and finishing material is significantly lighter than conventional construction methods, there is no insulation loss, construction time can be shortened, and costs can be significantly reduced. Furthermore, since it is a safe construction method that does not use fire, it will greatly contribute to the spread of external insulation construction. [Brief explanation of the drawings]
