Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for attaching a renovated sash frame to a renovated window by attaching a new sash frame to an existing old sash frame.

Prior Art Conventionally, a renovation method has been implemented in which a new sash frame is attached to an old sash frame attached to an opening in a building without removing the old sash frame.

In this case, a general building sash with an anchor attachment part and grooves formed on the outer circumference may be used as the new sash frame, but such a new sash frame can be placed over the old sash frame in a stable manner. In order to securely fix it, many metal fittings and auxiliary materials are required, and the mounting structure requires special ingenuity, and it also has the drawback that it cannot be expected to improve workability during installation.

Problems to be Solved by the Invention In view of the problems of conventional methods regarding refurbished windows, the present invention has been made to solve the problems quickly and without requiring particularly complicated work.
Another object of the present invention is to provide a method for attaching a refurbished sash frame that allows efficient installation of a new sash frame.

Means for Solving the Problem A sash holding frame consisting of an outer frame portion and an inner frame portion is used.

After the new sash frame is joined to the outer frame part of the sash holding frame, the inner frame part continuous to the inside of the outer frame part is fitted into the existing sash frame and fixed.

Operation The use of a sash retaining frame simplifies the installation of a new sash frame into an opening in a building without the use of many hardware or auxiliary materials.

Example Examples of the present invention will be described below.

The new sash frame A is formed by connecting upper and lower frames 1 and 2 and left and right vertical frames 3 and 4 made of aluminum alloy. This sash frame A is not specially designed for renovation, but is a ready-made product designed with standard dimensions for ordinary building sashes.

The sash holding frame S for attaching the sash frame A is composed of an outer frame part B having an attachment part for the sash frame A, and an inner frame part C which overlaps with the existing old sash frame D. These inner and outer frame portions B and C are constructed by connecting upper and lower frames 5 and 6 and left and right vertical frames 7 and 8, which are integrally extruded.

The four circumferences of the outer frame part B cover the outer circumferential side of the new sash frame A, and the inner surface has attachment parts 9, 10, 1 for engaging and coupling with the outer periphery of the sash frame A.
1, 12 are provided, and these mounting portions 9, 10, 1
The inner dimension l1 of Nos. 1 and 12 is larger than the inner dimension l2 of the inner frame portion C, and therefore the sash holding frame S is stepped between the outer frame portion B and the inner frame portion C. There is.

This sash holding frame S is the outer frame part B at the same time as the frame.
It is attached and held by the sash frame A, and in this state it can be attached to the opening of the building without cutting the surrounding outer wall 21.

The old sash frame D made of steel is attached to the building opening without being removed, and the inner frame C is fitted into the internal space of the old sash frame D, and the inner frame C and the outer frame are connected. The old sash frame D is brought into contact with the outdoor surface of the stepped part of the boundary with B.

At this time, since there is no place on the old sash lower frame 13 where the stepped part A comes into contact, attach the auxiliary metal fitting 14 of the mold in advance and abut against the vertical wall 15 of this auxiliary metal fitting 14. Also, on the old sash Spacers 19, 20, 20 are installed between the frame 16, the left and right old sash vertical frames 17, 18, and the inner frame portion C, and these spacers 19, 20, 20 allow
The outer frame part A is designed not to interfere with the outer wall 21 of the building. As shown in FIG. 3, the spacer 20 for the vertical frames 17 and 18 is made up of stepped and bent old sash frame contact parts 20b connected to both sides of an inner frame contact part 20a. . This spacer 20 is fixed in advance to the old sash vertical frames 17 and 18, and by fitting and fixing the inner frame C into the old sash frame D, the inner frame C covers the old sash frame D. hidden,
The new sash frame A is attached to the window opening via the integrally connected outer frame part B.

The installation of the new sash frame A, which is a renovated sash frame, to the window opening is easy because the inner frame portion of the sash holding frame to which this new sash frame is attached is simply superimposed and fixed onto the old sash frame. Further, the new sash frame can be attached to the outer frame at a safe location other than the opening of the building, and the attachment can be ensured.

In addition, in this embodiment, the opening dimension l3 of the sash frame A held in the sash holding frame S is:
Although it is somewhat smaller than the opening dimension l4 of the old sash frame D, the inner dimension l1 of the attachment part of the outer frame part B is larger than the opening dimension l4 of the old sash frame D, so the opening dimension l3 of the sash frame A is It is larger than when it is fitted into the old sash frame and polymerized and bonded using the conventional method, and a larger lighting area can be obtained compared to the conventional method.

Furthermore, the outer frame portion B of the new sash frame A hides the concave grooves in the anchor attachment portion on the outer peripheral side, resulting in a stable fit with a good appearance. and,
The metal fittings used for installation are Spacer 1
9, 20 and 14 auxiliary metal fittings, which is small.

In FIG. 4, the inner frame C is directly fixed to the old sash vertical frame 17 with screws without using the spacer 20. The method of attaching the sash frame for renovation is the same as in the previous embodiment.

In this case, since the left and right vertical frames 7 and 8 interfere with the outer wall 21 due to the absence of the spacer 20, it is necessary to remove the outer wall 21 by the amount of interference.
Since the inner frame C and the old sash vertical frame 17 are closely fixed, the opening dimensions of the remodeled sash frame A are almost the same as the opening dimensions of the old sash frame D, and are the same as when the old sash frame was installed. Ample lighting area can be secured.

Effects of the Invention In the present invention, after the new sash frame is joined to the sash holding frame, the inner frame of the sash holding frame is overlapped and fixed to the old sash frame, so compared to the conventional method, various metal fittings are required. It requires almost no materials or auxiliary frame materials, and it is extremely easy to install ordinary building sash frames.
Contributes to improving work efficiency.
