Description

[Detailed Description of the Invention] The present invention relates to a heat insulating structure for a multi-window mullion in which a pair of sashes connecting an inner and outer window frame via a heat insulating material are fitted and connected to a multi-window mullion.

In conventional multi-window mullions, when the sashes on both sides of the mullion were tightened and fixed, the pair of sashes connected via a heat insulating material were sometimes bent and deformed by the tightening force. Furthermore, in order to prevent the above-mentioned drawbacks, if the inner and outer sashes were connected and secured with a metal plate, heat bridges would occur and the number of man-hours for screwing would increase.

The present invention provides a heat insulating structure which eliminates the above-mentioned drawbacks and improves factory productivity.The details of the embodiments will be explained below with reference to the drawings. The figure is a cross-sectional view of a multi-window mullion according to the structure of the present invention. Standing in the center of the figure is a continuous window stand 1, and a pair of heat insulating sashes 2 are fitted and fixed on both the left and right sides of it. First, to explain the mullion 1, the embodiment is made of an aluminum section, and its cross section is a hollow rectangle, and flanges 3 protrude from both sides of the end surface on the outdoor side, and heat insulating packing is fitted on the indoor side of the flange. A C-shaped groove 5 for mounting is provided in the longitudinal direction. A screw retainer 7 for screwing a heat insulating clamping plate 6, which will be described later, is provided on the indoor side end surface. In the embodiment, the screw retainer 7 is a deep groove formed continuously in the vertical direction, and a U-shaped groove 8 is formed in the vertical direction on both sides of the screw retainer 7, in which the heat-insulating clamping plate 6 can slide within the groove width. There is. The heat insulating clamping plate 6 is made of hard neoprene or the like having heat insulating properties, and has a protrusion 6a on one side of the board for engaging with the U-shaped groove 8.
However, a steady rest protrusion 6b is provided on the other surface. Reference numeral 9 denotes an end pressing plate which serves as a reinforcing material or washer for pressing the heat insulating clamping plate 6, and has a trapezoidal cross section and a hole for inserting a screw 10 in the center.

Next, the insulation sash 2 has the inner frame and outer frame connected to the insulation material 1.
1, and the inner frame and outer frame are thermally isolated from each other. In the figure, an inner vertical frame 12 and an outer vertical frame 13 are connected together with a plurality of screws 10 via a connecting heat insulating material 11. Indicates a state in which On the outer surfaces of the inner vertical frame 12 and the outer vertical frame 13, at least two locking receiving portions 14 are disposed vertically in the longitudinal direction integrally with the frame members 12 and 13. The locking receiver 14 of this example has an inverted L-shape that stands up from the outer surface and has a rounded tip edge, and the height of the locking receiver 14 is the same for each of the locking receivers. be. Reference numeral 15 denotes a heat insulating connecting plate made of hard neoprene or the like, one side of which can be brought into close contact with the outer surface of the mullion 1, and in both embodiments, they are in contact with each other on a flat surface. The other surface of the heat insulating connecting plate 15 is provided with a plurality of locking protrusions 16 for fitting into the locking receiving portions 14 of the vertical frame, and the cross-sectional shape of the head, which is the tip thereof, is approximately circular. be.

To briefly describe how to attach the insulation sash 2 to the mullion 1, the insulation sash 2 is assembled into a rectangular shape at the factory, and then the outside of the vertical frame is passed through the inner and outer frames.
A plurality of heat-insulating connecting plates having heat-insulating performance are fitted with one touch. In this case, the locking receiving part 14 of the vertical frame is crimped by the head of the locking protrusion 16 and becomes integral with the vertical frame, so the rigidity of the vertical frame in the expected direction is strengthened, and the vertical frame can be attached to the mullion at the site. It can prevent bending and deformation when tightened. On the other hand, when assembling in a factory, the number of steps for screwing can be omitted, and productivity in mass production can be improved. Then, the pair of heat insulating sashes 2 fitted with the heat insulating connecting plates 15 are installed at the site.
By bringing them into contact with each other and screwing the end pressing plate 9, the heat insulating sash 2 is tightened through the heat insulating clamping plate 6 and securely fixed between the mullion 1 and the clamping plate 6.
As a result, in the multi-window mullion with the above-described structure, the outer vertical frame in contact with the outside air temperature is insulated from the indoor vertical frame, and the mullion 1 is also insulated by the insulating connecting plate 15 and the insulating clamping plate 6.
The intervening structure provides insulation from the indoor side, preventing heat flow due to heat transfer in the multi-window mullions, and there is no condensation on the indoor side even in winter. Note that 17 is a decorative batten.
