Description

Multi-layer glass of step type for building}

The present invention relates to step-type double-glazing for buildings, and more particularly, to quadruple-layered step-type double-glazing for buildings to maximize heat insulation and soundproofing effects.

In general, in a structure that supports the vertical load applied to a building and the horizontal load caused by wind or earthquake with only the frame of pillars and beams, which are the main structure of the building, the wall simply serves as a curtain to divide the space, so at this time The wall is called a curtain wall, and in Korean architectural terminology, it is called a non-bearing partition wall.

It plays the role of blocking rain and wind from the outside and blocking noise and heat, and the pillars and beams are not exposed to the outside, and the wall using glass is a modern architectural style and has a great function, especially for exterior use.

These curtain walls are particularly used in high-rise or high-rise buildings. That is, since it is difficult to assemble scaffolding from the outside in a building with a height of 100 m or more, a method of lifting and attaching exterior wall panels manufactured in a factory in advance is widely used.

If manufactured in a factory like this, mass production is possible, and the feature is that the panel is standardized and unified, and because of this, the exterior of the building also shows a new industrial configuration.

In the conventional curtain wall, a plurality of vertical frames are fixed to the upper and lower slabs at predetermined intervals, and a plurality of horizontal frames are coupled to the vertical frames at a predetermined height difference, and a double-glazed glass is placed between the vertical and horizontal frames. are installed side by side.

Here, the double-glazed glass is a glass window used in buildings for soundproofing and heat insulation to the inside of the building, and is one of the expensive high-quality building materials.

In recent years, residents have increased their desire to improve their satisfaction with the living environment in accordance with the high-end living environment, and accordingly, many remodeling works are being carried out on deteriorated buildings.

In particular, there are many cases where residents partially remodel according to their circumstances. Recently, it is urgently needed to reduce energy costs due to soaring oil prices. is preferentially preferred.

Such double-glazed glass secures the thermal comfort of indoor residents through improved insulation performance, can prevent condensation, and also improves soundproofing performance due to traffic noise, etc. to provide residents with a comfortable living environment. .

As conventional double-glazed glass, double-glazed glass and triple-glazed glass are provided, and these double-glazed glasses form an air layer by combining a spacer of a certain thickness between the inner rims of each glass, thereby insulating, Product development has been conducted to prevent condensation and improve sound insulation performance.

That is, as the number of double-glazed glass increases, the heat insulation performance, anti-condensation performance, and sound insulation performance are greatly improved. By doing so, the overall thickness is inevitably increased, and the manufacturing process is complicated, resulting in an increase in the manufacturing cost, which has the disadvantage of increasing the burden on consumers.

In addition, in the case of remodeling by constructing triple composite glass and quadruple composite glass on the window frame of an existing building, the standard of thick triple composite glass and quadruple composite glass does not match the conventional window frame, so the overall window frame There was a problem with a large cost burden, such as the need to replace the frame.

In particular, in order to install a window frame for applying triple-glazed glass or quad-glazed glazing, the entire wall thickness must be thickly constructed, and there is a problem that can be burdensome from the perspective of the constructor.

As shown, the step-type double-glazed glass 100 for a building according to an embodiment of the present invention includes an inner glass 110 disposed inside the building and an outer glass 120 disposed outside the building, , The inner glass 110 and the outer glass 120 may be spaced apart by a predetermined interval.

That is, the inner glass 110 and the outer glass 120 may be spaced apart by a distance corresponding to the thickness of the spacer 150 by coupling a spacer 150 having a certain thickness across the inner rim. there is.

For reference, the inter-bar 150 applied to the step-type double-glazed glass 100 for buildings according to an embodiment of the present invention may be molded and manufactured from a urethane foam material, and thus has a predetermined elasticity Of course, it may perform a function of absorbing moisture to prevent dew condensation.

In addition, the step-type double-glazed glass 100 for buildings according to an embodiment of the present invention is attached to one surface of the inner glass 110 by the first adhesive layer 112 having a predetermined thickness, and the first adhesive layer 112 The second adhesive layer 122 is bonded to one surface of the first step glass 130 and the outer glass 120 in a state where the space is spaced apart by the thickness of ), and the second adhesive layer 122 has a predetermined thickness. It may be configured to further include a second step glass 140 coupled in a state having a space spaced apart by a thickness of 122.

At this time, the overall length of the first step glass 130 is formed to be relatively short compared to the inner glass 110, so that both ends can be arranged stepwise, and the first step glass 130 is the inner glass ( 110), it is preferable to provide a thin one with a thickness of 1/2 or less compared to the thickness.

In addition, the overall length of the second step glass 140 is formed relatively shorter than that of the outer glass 120, so that both ends can be arranged stepwise. ) It is preferable that the thickness is also provided as thin as 1/2 or less compared to the thickness of ).

On the other hand, the first adhesive layer 112 for attaching the first step glass 130 to one side of the inner glass 110 and the second step glass 140 for attaching to one side of the outer glass 120 The second adhesive layer 122 may be butyl rubber, and is applied to a thickness of approximately 5 to 10 mm, so that the inner glass 110 and the first step glass 130, the outer glass 120 and the second step glass 140 Spaces spaced apart by intervals corresponding to the thicknesses of the first adhesive layer 112 and the second adhesive layer 122 may be formed.

Therefore, the first step glass 130 and the second step glass 140 are attached to each side of the inner glass 110 and the outer glass 120 by the first adhesive layer 112 and the second adhesive layer 122, respectively. When the first step glass 130 and the second step glass 140 are placed in a direction facing each other in the attached state, the inner edge of the inner glass 110 and the outer glass 120 has the first step glass 130 ) and the step with the second step glass 140, an empty space is formed. In this empty space, an inter-bong 150 is interposed so that both sides of the inter-bong 150 are inner glass 110 and outer glass 120, respectively. By being bonded with the facing inner surface of, the inner glass 110 and the outer glass 120 are bonded in a spaced apart state by an interval corresponding to the thickness of the gap rod 150.

Therefore, compared to the conventional double-glazed glass 100 or triple-glazed glass 100, the overall thickness of the quadruple double-glazed glass 100 is provided, so that the window frame installed in the existing building is intact. While using, it is possible to replace and install the quadruple double-glazed glass 100 according to an embodiment of the present invention, which has the advantage of enabling remodeling to improve insulation performance, anti-condensation performance, and sound insulation performance at a low cost. .

In addition, since air passes through the spaced space between the first step glass 130 and the second step glass 140, the space between the inner glass 110 and the first step glass 130, the outer glass 120 The air flowing into the space between the first step glass 130 and the second step glass 140 does not generate a pressure difference with the space between the second step glass 140 and the inner glass 110.
