Description

{Finishing structure of building exterior having improved construct ability and fixing power}

The present invention is to finish the exterior wall with an insulating material and exterior wall tiles so that the exterior wall of the building exposed to the outside can have an insulating property and produce a beautiful appearance, but the installed insulation material and exterior wall tile can be constructed more firmly and quickly. It's about structure.

In general, exterior tiles are installed on the construction surface of the concrete wall constituting the building to prevent rainwater from permeating into the inside of the building and to beautifully decorate the exterior wall of the building when it rains. As exterior tiles, metal panels or stone tiles such as aluminum, hot-dip galvanized steel sheets, and stainless steel sheets with excellent durability are used.

Apart from such exterior tiles, insulators are also installed on the exterior walls to insulate the buildings. The exterior walls of the buildings are exposed as they are by wind or external impact. As they occur, it is necessary to securely fasten and bind them to the exterior wall.

Such a structure is disclosed in Republic of Korea Utility Model Registration No. 20-0379055 (Exterior Insulation Panel Combination Structure for Buildings). After installing by combining the insulation material and the exterior tile on the upper surface of the bent support bracket is seated inside and combined.

However, in the above technology, as the insulation material and the exterior tile are seated and installed on the horizontally bent support bracket, the load is concentrated on the support bracket and may be bent or damaged, and as the insulation material and the exterior wall tile are seated together on the support bracket, However, since the horizontal width of the bent support bracket is quite wide, a considerable cost is required to manufacture it. In addition, there is a problem in that the bonding force between the insulating material and the exterior tile is weak, so that it is often detached.

1 is a perspective view of an exterior wall of a building on which an exterior wall fixing member is installed according to the present invention. Referring to this, the exterior wall finishing structure according to the present invention is an exterior wall fixing member 10 fixed to the surface of the exterior wall 1, an exterior wall fixing member It consists of a heat insulator 20 coupled to the outer wall 1 and installed on the surface of the outer wall 1, and a tile adhesive layer 30 formed on the surface of the heat insulator 20 to which the exterior tile 40 is attached.

As shown in FIG. 1 , a plurality of outer wall fixing members 10 are installed to be spaced apart from each other along the width direction of the insulator 20 on the outer wall 1 in order to fix the insulator 20 to the outer wall 1 . The specific structure of the outer wall fixing member 10 is shown in FIG. 2 , the outer wall fixing plate 11 formed vertically so as to be fixed to the outer wall 1 by the fixing piece P, and the outer wall fixing plate 11 bent in the horizontal direction The insulating material spacer plate 12 is formed to be, and the spike 13 is formed to be bent again vertically from the end of the insulating material spacer plate 12 is provided.

Here, the outer wall fixing plate 11 is fixed to be face-to-face with the outer wall 1 by the fixing piece P, and the insulating material spacer plate 12 bent horizontally therefrom is a heat insulating material 20 installed in the vertical direction by its thickness. ) is spaced between And, the spike 13 is formed with a pointed end, it is easily inserted into the upper surface of the insulator 20 to fix the insulator 20 . In this way, the buffer filling layer 50 is formed in the space spaced up and down by the insulating material separation plate 12, which will be described later.

The insulating material 20 is to effectively block the heat transferred to the outer wall 1 of the building, and is expanded polypropylene (EPP), expanded polystyrene (EPS), extruded expanded polystyrene, expanded vinyl acetate (EVA), and expanded polyethylene (PE). ), foamed polyurethane (PU), non-woven fabric (PET), polyvinyl chloride (PVC), or any one selected from urethane foam may be used. Preferably, it is preferable to use expanded polystyrene or urethane foam, which is a styrofoam that is easy to process and has a low price, and retains heat due to the characteristics of the material.

As described above, the heat insulating material 20 is fixed to the outer wall 1 by the spikes 13 of the outer wall fixing member 10 installed in plurality in the longitudinal direction on the upper surface. Only the upper end of the insulating material 20 can be fixed to the outer wall (1). A plurality of pieces are installed in the horizontal and vertical directions of the outer wall 10 by the outer wall fixing member 10. At this time, the vertical and adjacent insulating materials 20 do not flow by external force, and are vertically and vertically by the outer wall fixing member 10. The buffer filling layer 30 is formed so as not to deteriorate the thermal insulation performance of the outer wall 1 by the spaced-apart space. Before the buffer filling layer 30 is filled in the space and hardened, insulator fixing pins 60 connecting adjacent insulators 20 in the vertical direction are installed to prevent the flow of the insulator 20 .

Here, the glass fiber has excellent elasticity together with the urethane foam resin, and while effectively buffering the external force acting on the exposed outer wall 1 surface, it is not worn due to excellent durability even in friction caused by the external force. In addition, as the glass fibers are entangled with each other to form micropores, the heat insulation effect can be improved by blocking air from the outside. At this time, if the amount of glass fibers mixed into the buffer filling layer 50 is less than 15% by weight, the thermal insulation performance is lowered, and if it exceeds 25% by weight, the glass fibers are entangled with each other and it is difficult to form micropores. In addition, talc is added to improve heat insulation, silica powder is added to improve dispersibility, and silica sol is added to increase the viscosity of the filled buffer filling layer 50 and accelerate curing.

In this way, the tile adhesive layer 30 is provided to bond the exterior tile 40 to the surface of the insulator 20 on which the buffer filling layer 50 is formed between the adjacent insulators 20 .

That is, the mixed material applied to the surface of the insulator 20 as the tile adhesive layer 30 is filled in the plurality of filling grooves 20a, and the combined area with the insulator 20 is increased to be more firmly coupled. As shown in FIG. 3 , the filling grooves 20a are formed with straight lines crossing the surface of the heat insulating material 20 at equal intervals along the longitudinal direction. At this time, the filling groove (20a) is formed to be concave in a trapezoidal cross-section that is widened toward the inside of the insulating material 20, as shown in FIG. Even if it is applied, it is preferable to be firmly coupled so as not to be separated from the surface of the insulator 20 . A method of forming such a filling groove 20a on the surface of the insulator 20 is shown in FIG. 5 , wherein the heating wires 70 spaced apart at a predetermined interval are heated by an external power source to move the surface of the insulator 20 in a predetermined manner. The depth of the filling grooves 20a can be easily formed at equal intervals.
