  • The present invention relates to a window, and more particularly, to an insulation and strength reinforcement structure for a sliding window that is capable of improving the insulation and strength of a double sliding window.
    •
  • Generally, windows or doors are mounted on open portions so as to block the interiors of buildings from the outside. At this time, window frames against which the windows or doors are supported are classified into wooden window frames and metal window frames in accordance with the materials used. Recently, the doors or window frames are made of plastic or synthetic resin like P.V.C.
  • A window having an opening and closing double structure includes a window frame having a plurality of indoor and outdoor rails disposed along the longitudinal direction thereof, a pair of indoor window sashes slidingly coupled to the indoor rails in such a manner as to be open and closed, and a pair of outdoor window sashes slidingly coupled to the outdoor rails in such a manner as to be open and closed.
  • In this case, the window frame and the window sashes are formed of rectangular frames assembled with a plurality of profiles made of synthetic resin. Further, a metal reinforcing material made of steel or aluminum is inserted into the respective profiles, thereby improving the reinforcing force and wind resistant performance of the window frame and the window sashes.
  • In this case, the window into which the metal reinforcing material is inserted is somewhat improved in the reinforcing force and wind resistant performance, but is not improved at all in the insulation performance.
  • Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an insulation and strength reinforcement structure for a sliding window that has reinforcing materials inserted into the profiles of a window frame and window sashes constituting a double sliding window, the reinforcing materials inserted into the indoor and outdoor sides of the profiles being different from each other to improve the insulation performance and wind resistant performance.
  • To accomplish the above object, according to the present invention, there is provided an insulation and strength reinforcement structure for a sliding window, the structure including: a window frame having a plurality of indoor and outdoor rails disposed along the longitudinal direction thereof; a pair of indoor window sashes slidingly coupled to the indoor rails in such a manner as to be open and closed; and a pair of outdoor window sashes slidingly coupled to the outdoor rails in such a manner as to be open and closed, wherein a profile constituting the window frame has a heat insulating material inserted into the indoor side of the internal portion thereof and a metal reinforcing material inserted into the outdoor side of the internal portion thereof.

  • It should be noted that the components of the drawings are denoted by the same reference numerals in the drawings even though they are shown in different drawings.
  • FIG.1 is a front view showing a sliding window to which an insulation and strength reinforcement structure for a sliding window according to the present invention is adopted, FIG.2 is a perspective view showing the main parts of the insulation and strength reinforcement structure for a sliding window according to the present invention, FIG.3 is a sectional view taken along the line I-I of FIG.1, and FIG.4 is a sectional view taken along the line II-II of FIG.1.
  • Referring to FIGS.1 and 2, an insulation and strength reinforcement structure for a sliding window 100 according to the present invention includes: a window frame 110 having a plurality of indoor and outdoor rails 111a and 111b disposed along the longitudinal direction thereof, a pair of indoor window sashes 120 slidingly coupled to the indoor rails 111a in such a manner as to be open and closed, and a pair of outdoor window sashes 130 slidingly coupled to the outdoor rails 111b in such a manner as to be open and closed, wherein a profile P1 constituting the window frame 110 has a heat insulating material 210 inserted into the indoor side of the internal portion thereof and a metal reinforcing material 220 inserted into the outdoor side of the internal portion thereof.
  • Hereinafter, an explanation on the configuration of the insulation and strength reinforcement structure for the sliding window 100 according to the present invention will be in more detail given.
  • First, the window frame 110 is formed of a rectangular frame through a plurality of profiles P1 made by means of extrusion molding. In this case, each profile P1 has a plurality of space portions S1 and S2 formed at the internal portion thereof. The heat insulating material 210 and the metal reinforcing material 220 are inserted into the space portions S1 and S2 in such a manner as to be spaced apart from each other at the indoor and outdoor sides of the profile P1.
  • Referring in more detail to FIG.3, the heat insulating material 210 is insertedly mounted into the first space portion S1 formed at the indoor side of the profile P1 constituting the window frame 110, thereby improving the insulation performance and wind resistant performance of the window 100. In this case, preferably, the heat insulating material 210 has a honeycomb structure having a plurality of holes formed in the longitudinal direction of the profile P1. The heat insulating material 210 having the honeycomb structure is made of any one of paper, ceramic, synthetic resin, and aluminum.
  • Further, the honeycomb structure is generally made in an extrusion molding way. Each hole of the honeycomb structure does not need a hexagon shape necessarily, and may have a polygonal shape such as a square shape and so on. The honeycomb structure has some advantages in that the surface is large, the weight is light, and the anisotropy of the mechanical strength is high. Accordingly, the honeycomb structure is generally used for the heat insulating material and light weight structure material.
  • The metal reinforcing material 220 is insertedly mounted into the second space portion S2 formed at the outdoor side of the profile P1 constituting the window frame 110, thereby improving the sagging and bending prevention and wind resistant performance of the window 100. In this case, preferably, the metal reinforcing material 220 is formed of a bar having the length corresponding to the horizontal and vertical sizes of the profile P1. The metal reinforcing material 220 is made of any one of steel, stainless steel, and aluminum.
  • So as to improve the heat insulation performance and wind resistant performance, on the other hand, the indoor window sashes 120 and the outdoor window sashes 130 have different reinforcing materials inserted into the interiors of the profiles P2 and P3 constituting the frames thereof.
  • For example, the profiles P2 constituting the indoor window sashes 120 have a first reinforcing material 310 made of fiber reinforced plastic FRP insertedly mounted into the internal portions thereof. The FRP is made by combining thermosetting resin like unsaturated polyester, epoxy resin and so on with aromatic nylon fibers like glass, carbon, Kevlar and so on. The FRP has some advantages in that it is stronger than iron and lighter than aluminum, it is not rotten, and it is easy in machining process.
  • Further, the profiles P3 constituting the outdoor window sashes 130 have a second reinforcing material 320 made of a metal material insertedly mounted into the internal portions thereof. In this case, preferably, the second reinforcing material 320 is made of any one of steel, stainless steel, and aluminum.
  • That is, the indoor window sashes 120 are generally brought into contact with the indoor space side. Accordingly, the first reinforcing material 310 made of the FRP is applied to improve the heat insulation performance of the indoor window sashes 120.
  • Contrarily, the outdoor window sashes 130 are generally brought into direct contact with the external air of the outdoor space side, and thus, they need relatively high wind resistant performance. Accordingly, the second reinforcing material 320 made of the metal material is applied to improve the wind resistant performance of the outdoor window sashes 130.
  • Referring to FIG.4, the first reinforcing material 310 is applied to the four profiles P2 constituting the indoor window sashes 120, respectively, but the present invention is not limited to the preferred embodiment. For example, the first reinforcing material 310 may be restrictedly inserted into the horizontally disposed profiles P2 having relatively lower load than the vertically disposed profiles P2. That is, the first reinforcing material 310 made of the FRP is inserted into the horizontal profiles P2 having relatively lower necessity in structural reinforcement than the vertical profiles P2, and the second reinforcing material 320 made of the metal material is inserted into the vertically disposed profiles P2.
  • Under the above-mentioned structure, the sliding window 100 to which the insulation and strength reinforcement structure for a sliding window according to the present invention is applied can be selectively adopted and used at the places where high insulation performance and wind resistant performance are needed. Especially, after considering the climate of the area to which the window 100 is installed and the wind pressure caused by the height of the building at which the window 100 is installed, appropriate reinforcing materials are differently applied to the window frame 110, the indoor window sashes 120 and the outdoor window sashes 130, thereby providing the window 100 having the optimized insulation performance and wind resistant performance.
  • [Example 1]
  • Hereinafter, the heat insulation and air tightness performance of the window to which the present invention is applied will be in more detail explained with reference to tests. FIGS.5 to 10 are test reports of the sliding window to which the insulation and strength reinforcement structure for a sliding window according to the present invention is adopted.
  • As shown in FIGS.5 to 10, test methods are based on window insulation (KS F 2278:2008) and air tightness (KS F 2292:2008).
  • The heat transmission coefficient of the window 100 is 0.934W/(m2ㆍK) after the test environment where a temperature is 23.0±5.0℃ and humidity is 50±10%R.H.(For your reference, the heat transmission coefficient is a calorie passing through a unit surface material (wall, window and the like), and the lower the coefficient is, the better the heat insulation performance is).
  • Further, the air tightness of the window 100 is 0.40m3/(hㆍm2) after the test environment where a temperature is 23.4±0.3℃ and humidity is 49±1%R.H.
