The present invention relates to a coupling structure of the chassis frame, and more particularly, the connection portion of the chassis frame is further improved so that the coupling structure of the chassis frame, which is doublely installed on the windows used in the balcony of the veranda which is directly in contact with the outside air of the building, is further improved. The present invention relates to a coupling structure of a chassis frame which is formed of structures that are firmly supported to each other and is effective in preventing problems such as heat insulation, noise, or condensation, and can be easily formed without an accompanying member to shorten working time.

In general, double windows are mainly used for balcony of balcony of a building, and the chassis used for this is usually made of PVC or aluminum chassis. In the double-window structure, the external chassis is directly exposed to the external environment outside of the building, so the thermal conductivity is low, resulting in a poor heat insulation effect, which causes condensation in winter. In the inner direction, since the air with low thermal conductivity does not flow well into the room, a relatively good PVC chassis is used in terms of sound insulation and heat insulation efficiency.

In recent years, a small living room has been remodeled to expand the living room. As a result, windows existing on the boundary between the living room and the veranda are dismantled and double windows are installed on the outside of the veranda already installed. Problems such as draught immediately flows or condensation occurs. 1 and 2 illustrate a chassis structure of a conventional general dual frame, and FIG. 1 is a structure in which a high chassis frame 10 and an aluminum chassis frame 20 are directly connected, and FIG. 2 is a high chassis frame 10. The frame width is widened between the aluminum chassis frame 20 and an aluminum pipe 30 having a predetermined thickness.

In FIGS. 1 and 2, an aluminum chassis frame 20 is installed at an outer side of the high chassis frame 10, that is, at an outer side thereof. A window rail 11 is formed at an upper center portion of the high chassis frame 10, and an inner protrusion 12 and an outer protrusion 13 protrude upward from left and right ends spaced apart from the window rail 11 by a predetermined distance. do. In addition, a window rail 21 is formed at an upper center portion of the aluminum chassis frame 20, and an inner protrusion 22 and an outer protrusion 23 are formed at left and right ends separated from the window rail 21 by a predetermined distance. . Meanwhile, each of the frames 10 and 20 is inclined downward from the inner side to the outer side so that the window rails 11 and 21 and the inner protrusions 12 and 22 and the outer protrusions 13 and 10 of the respective frames 10 and 20 are inclined downward. Water introduced by condensation or rainwater is discharged through the drainage grooves 11a, 13a, 21a, 22a, and 23a formed in 23).

Although the conventional structure as described above is easily drained, it is fixed by silicon or the like in a state in which the close coupling is not made with each other, so that a gap occurs over time, and deformation is made so that opening and closing of the windows is not smooth. There was such a disadvantage.

In order to supplement the above problems, a number of techniques having various structures and coupling means have recently been disclosed. In particular, Patent Publication No. 2003-0004247 described with reference to Figure 3, consisting of a window rail 41 and the inner protrusion 42 installed upward in the center portion of the high chassis frame formed with a coupling groove 34 on the other coupling surface ( 40 and an aluminum chassis frame 50 formed of a window rail 51 and an outer protrusion 52 which are upwardly installed in the center, and having a coupling groove 54 formed on the other side of the coupling frame, respectively. The drainage grooves 41a, 51a and 52a are formed in the window rails 41 and 51 and the outer protrusions 52 to facilitate the discharge of moisture introduced by condensation, and the high chassis frame 40 and the aluminum chassis frame. The technique has already been disclosed which is provided with a coupling means 60 coupled to the defect grooves 44 and 54 of the 50 so as to be fixed by the male screw 60a.
