Abstract

PURPOSE:To easily fix a sash with high water-tightness. CONSTITUTION:The groove 1a of a sash 1 is filled with an expanded resin 2, and the sash 1 is fixed with screws 1 to an outer wall 3 during period when the resin 2 is expanding. The resin 2 being expanded can be closely attached along the surrounding shape of the screw 4 including hole formed when piercing the screw 4 into the peripheral wall and web of the groove 1a in the uneven outer wall 3. The resin 2 hardened can easily ensure the water-tightness of the complicated surrounding shape of the screw 4 and the finely uneven shape of the outer wall 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a sash to a window opening in a building.

0002

[Prior Art] A conventional method of attaching a sash is shown in Fig. 2(a).
) and (b), the watertight material 102 is loaded inside the grooved part 1a of the sash 1, and the tips of both flanges 1b of this grooved part 1a are in contact with the outer wall surface 3, and the sash is closed. 1 is fixed to the outer wall surface 3 with screws 4.

0003

[Problems to be Solved by the Invention] In the conventional sash mounting method, the watertight material 102 elastically deforms into the same shape as the planar shape of the outer wall surface 3 to ensure watertightness. If there are irregularities, the watertight material 102 due to the irregularities
Since elastic deformation of the material is difficult to occur, it is difficult to ensure watertightness. Furthermore, when the screw 4 penetrates, the watertight material 102 may be damaged and the watertightness may be impaired.

[0004] An object of the present invention is to provide a method for attaching a sash that can easily ensure watertightness.

[0005]

[Means for Solving the Problems] The sash mounting method of the present invention involves filling the inside of the grooved portion of the sash with foamed resin, and fixing the sash to the outer wall surface with screws while the foamed resin is being foamed. be.

[0006]

[Operation] The sash mounting method of the present invention is such that the sash is screwed to the outer wall surface while the foamed resin filled inside the grooved portion of the sash is being foamed. The foamed resin comes into close contact with the peripheral surface, the outer wall surface, and the peripheral surface of the screw.

[0007]

[Embodiment] A method for attaching a sash according to an embodiment of the present invention is as follows:
As shown in FIGS. 1(a) and 1(b), a foamed resin 2 is filled inside the grooved part 1a of the sash 1, and while the foamed resin 2 is being foamed, both flanges 1b of the grooved part 1a of the sash 1 are filled with foamed resin 2. The sash 1 is fixed to the outer wall surface 3 with screws 4 with the tip thereof in contact with the outer wall surface 3.

[0008] The sash 1 is made by framing a sash bar, which is an aluminum fitting obtained by extrusion molding, and a window (
(not shown). The groove-shaped part 1a is provided at the outdoor peripheral part of the sash 1, and is provided with a foamed resin 2 and a screw 4.
The side wall is constituted by a pair of flanges 1b that protrude parallel to each other with an interval that allows storage of the flange. The protrusion 1c can position the sash 1 in the lateral direction with respect to the circumferential wall of the opening 5 by bringing its tip into contact with the circumferential wall of the opening 5. As the foamed resin 2, foamed urethane, foamed phenol, foamed butyl rubber, or the like is used. It takes about 30 to 90 minutes from foaming to hardening of these resins.

[0009] Regarding construction, the inside of the groove-shaped portion 1a is filled with foamed resin 2. While the foaming resin 2 is being foamed, the sash 1 is attached along the corner portion formed by the outer wall surface 3 and the peripheral wall of the opening 5. That is, the sash 1 is attached to the outer wall surface 3 with the tips of both flanges 1b of the grooved portion 1a in contact with the outer wall surface 3, and with the tips of the projections 1c in contact with the peripheral wall of the opening 5. The sash 1 and the outer wall surface 3 are fixed by screwing into the outer wall surface 3 screws 4 passed through the web of the grooved portion 1a from the outside. After about 30 to 90 minutes have passed from the time when the foamed resin 2 is filled into the groove-shaped portion 1a including the above steps, the foamed resin 2 hardens to ensure watertightness between the sash 1 and the outer wall surface 3. .

Since the sash 1 is fixed to the outer wall surface 3 by the foamed resin 2 filled in the grooved part 1a and the screws 4 passing through the web of the grooved part 1a, the foamed resin 2 in the process of foaming is It is closely attached along the shape of the wall surface 3, the peripheral wall of the groove-shaped portion 1a, and the shape around the screw 4 including the through hole formed when the screw 4 penetrates the ceiling of the groove-shaped portion 1a. As a result, when the foamed resin 2 hardens, it is possible to easily ensure the watertightness of complex-shaped parts such as minute irregularities on the outer wall surface and the shape around the screws 4.

[0011]

Effects of the Invention: The sash mounting method of the present invention fixes the sash to the outer wall surface using the foamed resin filled in the grooved portion and the screws passing through the web of the grooved portion. It is possible to closely adhere the foamed resin along the shape of the outer wall surface, the peripheral wall of the grooved portion, and the shape around the screw including the through hole of the screw. For this reason, the foamed resin hardens and it is easy to ensure watertightness of the minute irregularities on the outer wall surface and the complicatedly shaped parts around the screws.
