Abstract

The present invention relates to a multilayer glass in which a method and a drop-proof metal mesh are installed in the multilayer glass. In the past, the metal mesh and the inner and outer panes contacted the target object by internal pressure or air circulation, and condensation occurred on the contact portion between the glass and the metal mesh. The metal mesh discolored and became unclear in the multi-layer glass space, and a defect occurred to reduce heat insulation effect in the air layer by transferring heat between the inside and the outside of the glass plate and the liver rod.

The present invention prevents condensation from occurring on the contact area between glass and metal mesh by interposing the gap between the inside and outside of the glass plate through the gap retaining opening of the rod, and by filling the filler (synthetic resin) adhesive with heat transfer and It is to block cold bridge and maximize airtightness and insulation.

Description

Grill double glazed window frame aggregate (single bar) {PAIR GLASS in GRILLES and SPACER BAR}

The present invention relates to a multi-layer pane, and more particularly to a multi-layer pane that can be used as a security window and safety by installing a metal mesh in the interior space of the double-layer pane.

In the case of low-rise commercial buildings as well as residential houses such as private single-family homes or multi-family houses such as apartments, it is common to install security metal shutters on the windows. However, the installation work is cumbersome and expensive to install the metal insole in the window like this, and after the installation, the appearance is unsightly, and in the case of an emergency such as a fire, these insoles can cause serious damage to life and property. There is concern.

Thus, by installing a grid of metal mesh in the interior space, the laminated glass was designed as Utility Model Publication No. 94-8521, so that the laminated glass itself can have a function of a security window and a safety belt. However, such a conventional multilayer glass is constructed such that a lattice provided therein is supported in contact with the glass so as to overcome the pressure applied to the multilayer glass even when the interior space is kept in a vacuum state.

However, when the lattice and glass come into contact with each other, condensation occurs at the part where the metal mesh lattice is brought into contact with the glass, causing a discoloration. In particular, the lattice made of metal conducts heat between the multi-layered glass, so There was a fatal flaw that diminished the adiabatic effect of existence.

In addition, in the conventional multilayer glass as described above, in order to ensure that the glass and the metal mesh are firmly coupled, a separate support frame must be installed outside the edge, and the external support frame is limited to its use by changing the external specification of the multilayer glass. There was a flaw received.

As the conventional multilayer glass as described above has a structure in which a metal spacer is attached between the inner and outer glass, condensation occurs when water droplets condense while heat conduction occurs through the spacer when the temperature of the indoor / outdoor is significantly different.

For example, in the winter season, the interior of the room is kept warm by the operation of the heater, and the outdoor is not heated to maintain the low temperature as it is in the natural state. Accordingly, the warmth of the room is lost to the outdoor side as the heat conducts through the spacer of the metal material, and condensation occurs due to the temperature difference on the inner and outer glass surfaces in contact with the spacer in the process.

The generated water droplets acted as a factor of reducing the life of the multilayer glass by lowering the adhesive force of the adhesive applied between the inner and outer glass and the spacer and lowering the function of the member fixing the inner and outer glass.

In addition, the spacer of the metal material has a weak structural strength in the shear force generated during deformation and expansion and expansion of the frame due to the weak rigidity, and because it is not elastic, it can not cope with the pressure change of the expansion and contraction of the internal air due to cross-crossing and crossover year The phenomenon that the binding force of the lowered was brought, resulting in poor adhesion.

The present invention has been devised to solve the above problems, by applying a thicker filler between the plate glass and the liver (spacer) and configured to block the heat conduction, even if the temperature difference between the indoor and outdoor is remarkable, the heat conduction through the spacer does not make condensation phenomenon. It is to provide a spacer structure for a double glazed glass window frame aggregate to prevent.

Thus, in the present invention, in installing a metal mesh between the panes of the multilayer, the gap holders 8 and the protrusions 81 are provided inside the edges of the panes 1 and 2 installed on the trunk rods 3 such gaps. By maintaining the metal mesh can be spaced apart from the plate glass to eliminate the fear of discoloration due to condensation phenomena and to maintain the heat insulation effect by blocking the heat transfer described this invention by the accompanying drawings Same as
