Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an opening from the indoor side to an opening in a building where it is impossible to attach a sash frame from the outdoors because a grid or handrail is attached to the outdoor side. The present invention relates to a corner piece for the upper end of a window frame that allows the sash frame to be completed easily.

Generally, a satsushi installed in an opening is installed after ensuring that the outdoor side of the opening is protected from rain.
For example, even if the structure is a newly built house, a panel lattice may be installed on the outdoor side of the opening by mistake, or a handrail may be installed above the exterior of the opening from the bottom of the eaves enclosure. There are many cases where it is impossible to install a sash from outside due to the fact that the sash is already built, and it is necessary to replace the existing sash with a new sash after a long period of time has passed after construction, or to install a replacement sash on top of the existing sash. When installing the satsushi, there are many cases where it is not possible to install the satsushi from outside like this.

Conventionally, when it is not possible to attach a sash, especially a sash frame, to an opening from outside, it is not possible to use a sash frame that is assembled in a factory by fixing the frame materials on all four sides with tapping screws or corner screws like a normal sash. Even if you try to install the sash frame immediately into the opening of the building on the site, it is impossible to install it to the opening on the outdoor side, and because the flange protrudes toward the outside for rain protection, it is difficult to install the assembled sash frame through the opening. Since it cannot be taken outdoors, the upper frame, lower frame,
The left and right vertical frames were attached to the openings on site, but with the sash frames constructed in this way, the connections between the sash frame materials were not securely established and the buttons did not close, resulting in poor strength and poor weather protection. It had undesirable drawbacks, being unsatisfactory both in terms of quality and finished appearance.

As a result of various studies to eliminate such drawbacks, the inventor of the present invention found that a normal surface grid installed on the outdoor side of the opening has a distance of 150 mm or more from the outer surface of the opening, and that Even if there is an eaves above and a handrail is installed upwards from below, a normal handrail has a distance of 85 mm from the outside of the opening, so such a distance should be used effectively. We have succeeded in developing a corner piece for the upper end of a window frame that is effective for completing a sash frame with a protruding flange for use from the indoor side and a sash frame with a protruding flange for outdoor use. It was completed.

That is, the present invention has a horizontal part that goes over the upper end of the vertical web, and one end of the horizontal part is inserted in a state where it hangs down and comes into contact with the outer surface of the upper part of the web of the formwork, and is fastened with screws from the window opening side. a vertical frame fixing part having a female thread part; and a vertical frame fixing part which is provided horizontally at the lower end of the vertical part hanging down from the other end of the horizontal part, and is fastened with screws from the opening side while being in contact with the upper surface of the web at the end of the upper frame. an upper bolt fixing part having a female threaded part; and a positioning part having a through-hole for a tapping screw that protrudes in a shape from the indoor end of the horizontal part and is screwed into the seven langes on the indoor side of the upper bolt. The present invention relates to a corner piece for the upper end of a window frame.

An explanatory diagram showing the relationship with the frame, Figure 5 is an explanatory diagram of the operation of installing the upper frame on the three-sided sash frame shown in Figure 4, and Figure 6 is the sash frame completed by the operation shown in Figure 5. FIG.

In the drawings, reference numeral 1 denotes a corner piece of the present invention, which is constructed as described below.

Reference numeral 2 denotes a horizontal portion, which, when used to complete the sash frame, extends almost horizontally over the top end 7a of the formwork 7, as shown in FIGS. 2 and 3.

It is a 3-point vertical frame fixing part, and is provided hanging down from one end of the horizontal part 2. When in use, it is inserted into the vertical frame 1 as shown in Fig. 2, and its web abuts on the outer surface 7bK of the upper part. It has a female threaded portion 3a for fixing to the formwork 7 with screws 11 passing through the web of the formwork 1 from the window opening side in this abutting state.

Reference numeral 4 denotes an upper bolt fixing part, which is provided horizontally at the lower end of the vertical part 5 hanging down from the end of the horizontal part 2 on the opposite side from the vertical frame fixing part 3, and when in use, the second button As shown in FIGS. 3 and 3, the web is brought into contact with the upper surface 9a of the web at the end of the upper frame 9, and in this abutting state, the screw 12 penetrating the web of the upper frame 9 from the window opening side is placed on the edge. It has a female threaded portion 4a for being fixed to the frame 9.

6 is alignment +! : As shown in Fig. 1, it protrudes in a U-shape from the indoor end, and when used, the second
As shown in the figure, with the mat sealer 13 in contact with the indoor cylinder of the upper frame 9 and the flange end face of the upper frame 9 and the formwork 1, move the upper frame 9 to an appropriate position using the tapping screws 14. It has a tapping screw through hole 6a for fixing.

In order to complete a sash frame in an opening by working from the indoor side using the corner piece of the present invention having such a configuration, the following procedure is performed.

First, formworks 1 and 8 are fixed on both sides (right and left) of the lower frame 10 as shown in FIG. 4 using the same method of fixing ordinary sash frames.
For example, a three-sided sash frame without an upper frame 9 is prepared in advance by fixing it by a method such as tapping screws.

This three-sided sash frame may be manufactured with high precision at a sash manufacturing factory.

The cut upper frame 9 may be one that has been processed in advance to a size that can be installed and fixed between the upper ends of the two forms I and 8 of the three-sided sash frame described above.

The three-sided sash frame and upper frame 9 prepared in this way are connected and fixed to each other via the corner piece 1.
When installing this corner piece 1 at an opening in a building, before starting work, insert it into the upper part of both formworks 7 and 8 of the three-sided sash frame, and insert it into the outer surface 7b of the upper part of the web (hereinafter referred to as both formworks 7°8).
(The part number is represented by the number of the formwork 7).
or fix it with screws 12 by protruding the vertical frame fixing part 3 toward the vertical frames 7 and 8 while it is in contact with the upper web surface 9a at both ends of the upper frame 9. With the upper parts of both formworks 1 and 8 of the three-sided sash frame in contact with both sides of the upper frame 9, the upper frame 9 or both formworks 7 and 8 are newly brought into contact with the above-mentioned protrusion of the corner piece 1. This makes it possible to fix the above-mentioned protrusion of the corner piece 1 with screws from the opening side.

FIGS. 4 and 5 show the case where the corner piece 1 is fixed to the formworks 7 and 8 in advance.

When the three-sided sash frame and the upper frame 9 with the corner piece 1 fixed to either side are prepared in this way, the three-sided sash frame and the upper frame 9 are first transported to the vicinity of the opening inside the building, and then The three-sided sash frame is tilted obliquely to the opening so that the three-sided sash frame is brought out from the indoor side to the outdoor side without coming into contact with the opening.

As mentioned above, even if a grid is installed on the outdoor side of the opening, there is a gap of more than 150 cm between the outside of the opening and the grid, and a handrail is installed on the outdoor side of the opening. Even if the opening is closed, the gap between the outside surface of the opening and the handrail is more than 85 degrees, so by using this gap, the 30,000-satsushi frame can be positioned between the outside surface of the opening and the grid or handrail. be.

This is because the sash frame carried outdoors through the opening is a three-sided sash frame without the upper frame 9, so the forms 7 and 8 can be tilted somewhat with respect to the lower frame 10.

After the three-sided sash frame is thus brought out of the opening room of the building, the upper frame 9 is brought outside through the opening of the building, and one or both of the formworks 7 and 8 of the three-sided sash frame is pushed to the left or right. spread.

FIG. 5 shows a state in which the left formwork 8 is pushed out to the left.

When the button is pressed and expanded, a mat sealer is attached to the fixed parts of the lower frame 10 and the forms 7 and 8 to improve rain protection, so the forms 1 and 8 are adjusted to the deformation capacity of the mat sealer. Since the formwork 7.8 can be tilted relative to the lower frame 10 by the looseness with which the formwork 7.8 is fixed to the lower frame 10, and can be bent into a cantilever shape with the lower frame 10 as a fixed end, it can be easily pushed and expanded.

In this way, after one or both of the formworks 7 and 8 of the three-sided sash frame is pushed apart to the left and right, the upper frame 9 is installed between the upper ends of the spread out formworks 1 and 8. At the time of this installation, the projecting portion of the corner piece 1 is brought into contact with the upper frame 9 or the formworks 7 and 8 of the three-sided sash frame.

When the upper frame 9 is installed between the upper ends of both the formworks 7 and 8 in this way, a mat sealer 13 is attached to the abutting portions of these to completely seal off the rain, as shown in FIG.

A specific example of such an upper frame installation operation is, for example, as shown in FIGS.
8, the upper frame 9 is inserted so that one end of the upper frame 9 comes into contact with the protruding part of the corner piece 1 fixed to the formwork 8 on one side, that is, the upper frame fixing part 4, as shown in FIG. temporarily connect one end of the upper frame 9 and the upper part of the formwork 8,
Next, the expansion of the other formwork 8 is released, and the protruding tool of the corner piece 1, that is, the upper frame fixing part 4, which has been fixed on the formwork 7, is inserted into the other end of the upper frame 9, and the other end of the upper frame 9 is inserted into the other end of the upper frame 9. The ends and the upper part of the formwork 1 may be temporarily connected in the same way.

In addition, when the corner piece 1 is fixed to both sides of the upper frame 9, the protruding part of the corner piece 1 fixed to one end of the upper frame 9, that is, the formwork fixing part 3, is moved to the upper part of one of the rigid frames 7. The corner piece 1 fixed to the other end of the upper frame 9 is protruded by inserting the corner piece 1 into the upper frame 9 to temporarily connect the edge of the upper frame 9 and the upper part of the formwork 7, and then releasing the expansion of the other formwork 8. That is, the formwork fixing part 3 may be inserted into the upper part of the formwork 8 to temporarily connect the other end of the upper frame 9 and the upper part of the formwork 8 in the same manner.

When installing the upper frame 9 between the formworks 7 and 8 in the above operation, the mat sealer 13 is held in place as shown in FIG.

The reason why one or both of the formworks 1 and 8 is pushed to the left and right when temporarily connecting the formworks 7 and 8 of the three-sided sash and the upper frame 9 via the corner piece 1 is that the upper frame 9 Because the length of the upper frame 9 is the same as the length between the formworks 7 and 8, it is impossible to install the upper frame 9 between the formworks 7 and 8.
This is to prevent the mat sealer from being deformed or damaged when the mat sealer is attached to the contact portion between the upper frame 9 and the formworks 7 and 8.

In this way, the formwork 7 of the three-sided satsushi is formed through the corner piece 1.
, 8 and the upper frame 9 have been temporarily connected, they are permanently fixed in the following manner.

First, place the upper frame 9 in a predetermined position while sufficiently pressing the mat sealer 13 on its end surface, and then attach the corner piece 1.
A tapping screw 14 is screwed into the upper frame 9 that is in contact with the alignment part 6 through the tapping screw through hole 6a of the alignment part 6 from the opening side and fixed.

By performing this alignment at both ends of the upper frame 9, the position of the upper frame 9 is prevented from shifting in the direction perpendicular to the sash surface, and the work of inserting missing screw beams is facilitated. This can contribute to strengthening the fixation of the entire frame 9.

Next, the protruding part of the corner piece 1, that is, the upper frame fixing part 4
Alternatively, screw the screw 11 or 12 into the glasses part 4a or 3a of the formwork fixing part 3 from the opening side by passing through the upper frame 9 or the webs of the formworks 1 and 8, and tighten the upper frame 9 or the formwork 1, 8. Frame 7゜8
The satsushi frame that fixes to corner piece 1 is completed.

Therefore, the installation of the sash frame to the opening is completed by installing the sash frame in the opening of the building and fixing it with screws or other means.

As described in detail above, if the corner piece for the upper end of a window frame according to the present invention is used, the lower frame and the left and right formwork for buttoning on a conventional sash frame can be fixed in advance in a factory or the like in the same manner as before. The sash frame can be attached to the opening from the formed 30,000 sash frame and the upper frame by working from the indoor side.

By taking advantage of its flexibility to deform, the three-sided sash frame is brought outside through the opening, the upper space of the three-sided sash frame is expanded, the upper frame is installed, and the upper frame is fixed via the Kona Beads of the present invention. Even though it protrudes outward from the flange 3, it is easy to install and completes a perfect sash frame that can withstand rain.

The corner piece of the present invention is fixed to the formwork or upper frame of the three-sided sash frame in advance in use, and when installing the upper part of the three-sided sash frame, fixing is done only by screws and tapping screws from the indoor side. The work can be done firmly and easily, and it can be done easily when there is only a gap on the outdoor side of the opening.
In particular, when applied to replacement sashes that are installed on existing sash frames, the effect is very large, and its industrial value is extremely large.
