LT3777B - Method for renovation of windows and balcony doors - Google Patents

Abstract

The proposed invention applies to the renovation of windows and balcony doors. The aim is: the reduction of heat transmission coefficient of windows and balcony doors. The essence of the invention: renovation method of windows and balcony doors is distinguished by that the third glass, being installed into the window's outward casement or doors outward leaf inner side. Initially the outward casement or outward leaf are cut, both their parts along one rim are connected by hinges and then connected by bolts and special nuts. The useful effect: the windows and balcony doors heat transmission coefficient is reduced.

Description

The invention relates to the field of construction, specifically to the construction of windows and doors.

Known way to fasten windows with metal window frames. Attaches the glass to one end of the attachment piece through a hole made in the window frame. The other end of the piece is pressed firmly against the window frame (USSR Certificate No. 151007).

The disadvantage of this method is its narrow applicability as it can only be used in metal window frames.

Also known is the construction of the window, when the third glass is placed in a separate frame consisting of two parts. One part of the separate frame is hinged to the inner sash and the other fixed to the outer sash. The middle glass is separated by a double sash, a detachable clasp-type snap closure from the end of the shackle frame. When inserting or replacing the middle (third) glass, it is locked by a latch and a locking element (USSR Certificate No. 717266).

The disadvantage of this method is that a separate frame is required for the insertion of the third glass, which requires additional raw material and labor costs.

The object of the invention is to reduce the heat transfer coefficient of windows and balcony doors in operation by installing a third glass.

In order to achieve the above object, the invention has the following changes compared to the prototype described above: after separation of, for example, double-glazed window sashes, the inner sash of the outer sash is unbroken, a groove for the third glass is made; its two sides are joined together by hinges, then the outer sashes are joined together by bolts and special nuts.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate examples of the proposed renovation method for the types of windows and doors listed below. Figure 1 Window unit 30 with double sashes and double glazing, Figure 2 - window unit with separate hinges and double glazing, Figure 3 - Balcony doors with double sash and double glazing.

1. Renovation of wooden window units with double sashes and double glazing (Figure 1).

The double flap 1, 2 is removed from the frame 3 (a single flap can be temporarily inserted into the window opening if necessary). After unscrewing the screws 4 and hinges 5, the outer sash 1 is separated from the inner sash 2. The outer sash 1 is removed from the outer sash 1 after removing the glazing strips 6 and then cuts the groove 8 into the third glass 9 4 without breaking it. The outer sash 1 is cut lengthwise by a cut 10, the cut site is painted, and the two sashes 11, 12 are joined by hinges on one side 13. The outer sash 1 is joined by screws 14 and special nuts 15 to the outer sash 1. 7, seals them with silicone sealant 16 and secures them with glazing strips 6. After removing the glazing strips 6, seals the inner glass 17 in the inner flap 2 with a silicone sealant 16, inserts the inner glass 17 with glazing strips 6. Joins the inner flap 2 and the outer flap 1 15 into the double sash 1, 2 and insert into the jamb 3. When inserted into the st nail 3 has a double fastener 1, 2 and is sealed with a special profile porous rubber sealing gasket 18.

2. Renovation of wooden window units with separate hinges and double windows (Figure 2).

The outer sash 1 is removed from the casing 3. The outer sash 1, after removing the glazing strips 6, removes the outer glazing 7. It then cuts the groove 8 on the inner side of the outer sash 1 to the third glass 9 without being disassembled. , the incision is painted, the two sides of the sash 11, 12 are joined by hinges on one side 13. The outer sashes 1 are joined by screws 14 and special nuts 15. The outer sash 1 is fitted with glasses 7 and 9 and sealed with silicone sealant 16. 6. Attach outer flap 1 to frame 3 and seal with special profile porous rubber sealing gaskets 18. into frame 3 and seals the special profile porous rubber seal with gaskets 18.

3. Renovation of wooden balcony doors with double glazing and double glazing (Figure 3).

The balcony door is removed from the frame 3 (a single door can be temporarily inserted into the door opening if needed). The double sash 19, 20 separates the two screws 4 and the hinges 5 from one another. Remove the outer glass 7 from the outer sash 20 after removing the glazing strips 6, and cut the groove 8 on the third side 9 of the outer sash 20 without breaking it.

The outer sash 20 is cut transversely 50 to 60 mm below the outer glass 7 by a slit 21, then slit by a slit 10 along the transverse slice 21, and the sections are painted. The two sides 22, 23 of the upper part of the outer sashes 20 are joined by hinges 13 to one side, and subsequently the two sides 22, 23 are interconnected by bolts 14 and special nuts 15. The glazing 9 and 7 are mounted on the outer sash 20, sealed with glazing 16 6. After removing the glass strips 6, seal the inner glass 17 in the inner sashes 19 with a silicone sealant 16, re-attach the inner glass 17 with the glass sashes 6. Connect the inner 19 and outer 20 sashes with 5 bolts 4 and special nuts 15. The door 3 is sealed with a special profile porous rubber sealing gasket 18 between the balcony doors 3 and the door cavity 24 between the sashes 19, 20 below the glazing 7, 9, 17 is filled with heat insulating polystyrene.

Alternatively, a fourth glass can be inserted into the above types of windows and balcony doors in an analogous manner, using the outside of the inner sash or inner sash.

Compared to the prototype, the proposed way of renovating windows and balcony doors by installing a third glass allows reducing the heat transfer coefficient of windows and balcony doors (while reducing heat loss by 25-30%) without the need for additional raw materials and labor.
