Description

{External wall insulation system}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat transfer blocking structure of a building, and more particularly, to an outer wall insulation system of a building capable of dry thermal insulation.

As an effort to improve the global climate problem due to the recent greenhouse effect, the construction of buildings that minimize the energy consumption by increasing the heating and cooling efficiency of buildings is encouraged. In order to improve the cooling and heating efficiency of a building, there is an insulation method, an interrupted heat and an external insulation method based on a wall of a building. Until now, most of the buildings have been using thermal insulation and thermal insulation methods.

However, in the adiabatic method or the interrupted thermal method, there is a problem that heat bridging occurs due to disconnection between the adiabatic materials, and the adiabatic effect is remarkably deteriorated due to heat loss. In addition, such a disconnection may cause a difference in heat flow resistance, causing problems such as condensation and mold in a portion where the heat flow resistance is small. As a method for solving such problems, research on an external heat insulating method has been actively carried out, and most of the external heat insulating structures to date have been mainly applied by a wet method called dryvit (dryvit). However, the method using such a dry bit is limited in its application due to dropouts and cracks.

An object of the present invention is to provide an outer wall insulation system of a building which is applicable to an outer wall of a building, minimizes thermal bridges, and does not cause detachment and deformation of the insulation structure against changes in the external environment.

According to an aspect of the present invention, there is provided an outer wall insulation system for a building, comprising: a plurality of tracks spaced from each other in a first direction and including a first track and a second track fixed to an outer wall of a building; ; A plurality of splines including first and second splines spaced apart from each other in a second direction perpendicular to the first direction, between the first track and the second track; And at least one or more cellular adiabatic panels each inserted and fixed in a cell defined by the first track, the second track, the first spline, and the second spline.

In one embodiment, the first and second splines include a second partition wall portion extending in the first direction, respectively; And a second insertion portion extending in the first direction and having a constant width and extending in third and fourth lengths in both directions parallel to the second direction from the outer edge of the second partition wall portion, Sidewalls parallel to the second direction of the heat insulating panel include first trenches into which the first inserts of the first and second tracks are respectively inserted and sidewalls of the cellular thermal insulating panel, 1 and the second insert of the second splines, respectively.

In one embodiment, the surface of the first or second insert may include a pattern for enhancing fixation by insertion with the first or second trench. Further, the first and second splines are fixed by being inserted into the second trenches of the adjacent cellular thermal insulation patterns with the first and second splines respectively.

And the cellular thermal insulation panels are smaller in size than the first direction in the first direction outside the first partition toward the first trench. In this case, the size difference of the cellular thermal insulating panels in the first direction may be as much as half to thickness of the first partition wall.

In one embodiment, the cellular thermal insulation panels may be smaller in size in the second direction on the second partition wall side than on the second trench in the outer second direction. The size difference of the cellular thermal insulating panels in the second direction may be as much as half to thickness of the second partition wall.

In one embodiment, the first direction may be a direction perpendicular to the paper surface, and the second direction may be a direction parallel to the paper surface. In addition, the plurality of tracks and the plurality of splines may include polyvinyl chloride (PVC).

In one embodiment, the cellular thermal insulation panels may comprise a heat insulating main material layer comprising either a resin-based foam material or an inorganic heat insulating material. The cellular thermal insulating panels may further include a composite finish layer including at least two layers of an adhesive layer, a mesh layer, and a finish layer on the heat insulating main material layer.

According to the embodiment of the present invention, it is possible to construct the cellular thermal insulation panels by a dry method only by a plurality of tracks and a plurality of splines, thereby enabling an economical and simple construction, and by a plurality of tracks and a plurality of splines Since the cellular thermal insulation panels can be tightly fixed to each other without gaps, it is possible to provide an outer wall insulation system of a building that minimizes thermal bridging and does not detach and deform the insulation structure.
