DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a renovated window frame and a method for renovating a window frame, and more specifically to an improvement in a renovated window frame and a method for renovating a window frame by removing or removing an existing old window frame.

Renovated window frames and window frame renovation methods have traditionally included leaving the existing old window frame on the building frame and fitting a new window frame into the old window frame. Some windows are removed or removed and a new window frame is fitted and installed.

That is, as a conventional example of the former, for example,
Publication No. 8957, Special Publication No. 57-57592, etc.
It has been actually implemented and achieved considerable results.

By the way, since the former conventional example uses the old window frame, it is inferior in reliability in ensuring the installation strength of the new window frame over a long period of time. It has been proposed in Publication No. 210275, etc.

However, in these latter conventional examples,
It is installed using the inserts inside the building frame.
Since the positions of the insert bars vary, when fitting a new window frame with anchor members on the outer periphery and fixing the anchor members to the insert bars, the positions of the insert bars may differ between indoor and outdoor directions. Coupled with the fact that the window frame has relatively poor shape retention, it is difficult to install it correctly.

In addition, the most serious problem with the latter conventional example is that when the reinforcing bars and the frame are made of reinforced concrete, when fixing the anchor member to the reinforcing bars via other members,
Since the individual reinforcing bars are fixed to each other, the installation strength is significantly low. Therefore, the outer periphery of the new window frame must be filled with mortar and concrete, which is a time-consuming and labor-intensive renovation method. Not only that, but it would be impractical to prevent the filling from flowing outside, and if the leaked fluidic filling adhered to the renovated window frame and hardened, there was a risk that the window could not even be opened or closed.

Further, as a conventional example of the latter, there is also a technique disclosed in Japanese Patent Application Laid-open No. 58-83780.

This conventional technology involves exposing the fixtures of the existing frame to the remains of the existing frame, welding reinforcing bars to these fixtures, and then welding the connecting bars between the reinforcing bars and the fixtures (anchor members) set around the outer periphery of the new window frame. It is a technology that is connected by etc.

In this conventional technology, the reinforcing bars are welded to the fixtures of the existing frame, so the strength can be improved to some extent because the reinforcing bars are new members, compared to the method in which connecting bars are welded to the fixtures of the existing frame. can.

However, even when reinforcing bars are welded to the fixtures of the existing frame, the positioning of the reinforcing bars in the indoor and outdoor directions is insufficient, and the connecting bars are sometimes inclined in the indoor and outdoor directions, making it difficult to fit them. Due to the lack of standards for positioning new window frames indoors and outdoors, coupled with the relatively poor shape retention of new window frames, it continues to be difficult to install new window frames correctly.

Furthermore, even if reinforcing bars were welded to the fixtures of the existing frame, the strength would be insufficient, so it would have to be filled with concrete as described above, and in this respect, the technology is no different from the one described above. Ta.

Therefore, the present invention completely eliminates the problems of the latter conventional example (sometimes referred to as the drawing method).

That is, in the present invention, firstly, by removing the existing old window frame from the frame, a rectangular window fitting opening is formed in the frame when viewed from the front and back, and the outer periphery of the opening and the upper In a renovated window frame in which a window mounting recess is formed in the frame portion and the vertical frame portion, and a new window frame framed is fitted into the opening having the recess on the outer periphery and is attached to the frame, A plurality of rods are protruded inwardly from the frame at intervals in the longitudinal direction of the frame, and a base material is connected and fixed across adjacent rods at least in the longitudinal direction of the frame, and the base material is fixed in the longitudinal direction of the base material. A positioning member is made to protrude horizontally in the indoor-outdoor direction at intervals of , characterized in that anchor members provided on the outer periphery of the new window frame at intervals in the longitudinal direction of the frame and the base material are connected and fixed by a mounting member that is perpendicular to a horizontal plane in the indoor-outdoor direction. We offer refurbished window frames. Furthermore, in the present invention, by removing the existing old window frame from the frame, a rectangular window insertion opening is formed in the frame when viewed from the front and back, and the outer periphery of the opening and the upper frame part are formed. After forming a window mounting recess in the vertical frame portion, a new window frame framed is fitted into the opening having the recess on the outer periphery, and the frame is attached at intervals in the longitudinal direction of the frame on the outer periphery of the new window frame. In the side-mounted window frame renovation method, multiple rods are protruded inward at intervals in the longitudinal direction of the frame from the window mounting recesses of the frame from which the old existing window frame has been removed, and then at least in the longitudinal direction of the frame. By connecting and fixing the base material across adjacent bars and fitting the positioning member that protrudes horizontally from the base material in the indoor/outdoor direction into the window mounting recess, the base material can be used as a reference for mounting the new window frame. After positioning the new window frame indoors and outdoors, the framed new window frame is fitted into the opening, and each of the anchor members attached to the outer periphery of the new window frame and the base material are inserted into the room. To provide a method for renovating a window frame, which is characterized in that the window frame is connected and fixed by a mounting member that is perpendicular to an outward horizontal plane.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, the existing old window frame 2, which is rectangular in front and back view, is made of wood, iron, aluminum, etc., and includes an upper frame portion 2A, a vertical frame portion 2
B, consists of a lower frame part 2C, and in order to remove it, install a hydraulic jack 4, for example, across the opposing upper frame part 2A and lower frame part 2C, as shown in FIG. By bending the upper frame portion 2A and the lower frame portion 2C as shown by the chain lines in FIG. A rectangular window fitting opening is formed when viewed from the rear.

A window mounting recess 3 is formed in the upper frame portion and the vertical frame portion of the outer periphery of this opening, and a window mounting portion 3D having a drainage slope surface 3E is formed in the lower frame portion.

In addition, when carrying out the work, the position of the hydraulic jack 4 is changed each time, and in some cases, a chisel can also be used in conjunction with this to remove the window mounting recess 3. The interior and exterior of the frame, or both, may be cut using a concrete rotary cutter in the longitudinal direction of the frame.

In addition to the hydraulic jack, a chain block may be used, and one end of the chain may be provided with a hook, and the hook may be engaged with the frame and pulled.

In any case, as shown in FIGS. 2 and 3, a plurality of rods 5 are made to protrude inward from the frame 1 in the window mounting recess 3.

When the frame 1 is a reinforced concrete structure as shown in FIGS. 7 and 8, the bars 5 are used as they are, and the exposed parts of the bars 5 are treated with rust removal, etc. so that they become new surfaces. administer. When the exposure is insufficient, a portion of the window mounting recess 3 is patched, and then a surface finish or the like is applied.

When the bars 5 are reinforcing bars, they are arranged vertically and horizontally, so that a plurality of bars 5 are projected at intervals in the longitudinal direction of the frame.

In addition, if the spacing between reinforcing bars is large due to the reinforcement arrangement, or if the reinforcing bars are severely corroded, new metal bolts such as anchor bolts or anchor reinforcing bars should be installed between the 5 adjacent bars in the longitudinal direction of the frame, as shown in Figure 14. The bar material 5A is buried and fixed.

Next, as shown in FIGS. 4 to 8, the base material 6 is fixed to the bar 5 projected from the window mounting recess 3.

In other words, the intervals between the bars 5 are usually quite large, and since the bars 5 are existing ones except for the new bar 5A, it is necessary to reinforce them and ensure installation strength. A base material 6 made of an angle material, a bar material, a round bar, etc. is connected and fixed across the longitudinally adjacent bars 5.

In connection and fixation of the base material 6, as shown in FIG. It is brought into contact with either one or both of A and the outdoor side B, and is connected and fixed by, for example, welding 7.

Further, as shown in FIG. 8, the base material 6 may have a partial length in the longitudinal direction of the frame, and in this case, it is connected and fixed to two or three rods 5, so that the length in the longitudinal direction of the frame is at least the length of the base material 6. It is assumed that bars 5 adjacent in the direction are connected and fixed.

Further, as shown in FIG. 5, positioning members 6A protrude from the base material 6 at predetermined intervals in the longitudinal direction in the horizontal direction of the indoor and outdoor directions, and the positioning members 6A are connected to the inner and outer surfaces 3B of the window mounting recess 3, 3C, the base material 6 becomes the mounting standard for the new window frame.
This is advantageous in terms of connection and fixation with the bar 5, prevention of movement in the indoor and outdoor directions, and connection and fixation with the mounting member 9.

Therefore, when connecting and fixing the base material 6, the base material 6
A plurality of attachment members 9 of the anchor members 8 are fixed to the upper frame portion and the vertical frame portion by welding or screws, and in the case of the lower frame portion, a support member 10 is attached to support the new window frame from below. Multiple pieces are fixed.

Then, as shown in FIGS. 9 to 14, a new window frame 11 made of extruded aluminum material, extruded plastic material, etc., which has been framed in advance, is fitted, and the upper frame portion 11A and vertical frame portion 11B of the new window frame 11 are fitted. In this case, the anchor member 8 slidably fitted into the outer circumferential groove 11C is slid in the longitudinal direction of the frame, and the anchor member 8 is welded to the mounting member 9. The anchor member 8 is connected and fixed to the base material 6. That is, the mounting member 9 is attached to the base material 6 on which the mounting reference in the indoor/outdoor direction is set using the positioning member 6A.
The new window frame 11 is fixed by welding or the like and installed vertically to the horizontal plane in the indoor/outdoor direction, and the anchor member 8 is fixed to this mounting member 9 by welding or the like, so that the new window frame 11 is fixed in the specified direction in the indoor/outdoor direction. is fixed in position.

Further, the lower frame portion 11D is connected and fixed to the base material 6 via the support member 10 via screws 13' together with an external frame material 12 having a rain protection function.

The anchor member 8 has a claw leg 8A that engages with the outer circumferential groove 11C, and is slidable in the longitudinal direction of the frame but not movable in the width direction of the frame. A plurality of devices are installed in the outer peripheral groove 11C of the frame 11.

This device may be installed in the framework of the new window frame 11, or it may be installed individually from the indoor side A after the new window frame 11 is fitted.

In addition, in the illustrated example above, the mounting member 9 and the support member 10 are fixed to the base material 6 before the new window frame 11 is fitted, but both the mounting member 9 and the support member 10 are connected to the anchor member 8 and the lower frame portion 11D. It is also possible to leave it in a fixed state and attach it to the base material 6 later.

Furthermore, as shown in FIG. 15, a plate material is used as the base material 6, a turnbuckle structure having base plates at both ends is adopted as the mounting member 9, and the base plate is fixed to the base material 6 and the anchor member 8, respectively, and then the buckle is attached. If you turn the upper frame part 11
A. Not only can the deflection of the vertical frame portion 11B be corrected, but it can also be installed with the posture corrected.

Furthermore, as shown in FIG. 16, the mounting member 9 is perpendicular to the horizontal plane in the indoor-outdoor direction, but when it is oriented diagonally to the longitudinal direction of the frame, the distance between the frame and the new window frame can be narrowed. That's how wide the renovated window frame can be.

As a final finish, the internal frame material 13 and caulking material 14 are applied as shown in FIGS. 9 and 11.
All you have to do is fill it up.

As detailed above, according to the present invention, the window mounting recess formed in the upper frame/vertical frame portion on the outer periphery of the rectangular window fitting opening formed in the frame by removing the existing old window frame. A bar is protruded, and the bar is connected and fixed to the base material, and then the anchor member on the outer periphery of the new window frame that is fitted is connected and fixed to the base material. The window is renovated by reinforcing the side bars with the base material and attaching a new window frame to this reinforced rigid structure via anchor members. Therefore, the window mounting recess, that is, the frame side A renovated window frame that guarantees the required strength can be implemented quickly and with less effort without filling the space between the outer circumferential side of the new window frame and the outer circumferential side of the new window frame with resin concrete, mortar, or the like.

Furthermore, since there is no need for a filler, there is no need for the filler to adhere to the new window frame and harden due to leakage, thereby preventing problems with the opening and closing of the window.

In other words, a plurality of rods protruding into the window mounting recess are connected to each other with a base material to ensure rigidity, and this rigid base material and an anchor member attached to the outer periphery of the new window frame are attached to a horizontal plane in the indoor-outdoor direction. On the other hand, since the new window frame is connected and fixed via the mounting member on the vertical plane, the installation strength of the new window frame is sufficient, and there is no need to fill and harden mortar etc. in the gap between the frame side and the outer circumferential side of the new window frame as in the conventional case. There is no problem with opening or closing the windows due to mortar or other spills.

In addition, the base material that connects the plurality of rods to each other has a positioning member that protrudes in the indoor-outdoor direction and in the horizontal direction, and this positioning member is fitted into the window mounting recess to install the new window frame in the indoor-outdoor direction. Standards can be set using the base material, thereby making it possible to easily and accurately determine the position of the new window frame in the indoor and outdoor directions, thereby speeding up the renovation work.

In addition, in the case of a renovated window frame, the bars on the frame side are connected to each other by a base material, and a positioning member protruding from the base material prevents the base material from moving indoors or outdoors. Using the base material, which has a rigid structure, as a mounting reference, we connected the anchor member on the outer periphery of the new window frame to the base material using the mounting member, resulting in a renovated window that has excellent wind resistance and earthquake resistance, and also accurately aligns the indoor and outdoor positions. It can provide a framework, which is of great benefit.
