Description

[Detailed Description of the Invention] The present invention relates to a watertight structure that prevents rainwater from entering the building frame from the retaining portion of the short shutter frame and the sash frame that constitute the shutter frame.

Generally, when a separately formed storm door frame is installed on the outdoor side of the sash frame, as illustrated in FIGS. After fixing them by overlapping them between the mounting piece 2 to the frame 3, which is vertically installed below the outdoor side of the sash bottom frame A, and the frame 3, the left and right shutter frames 4 and 5 are attached to the building frame 3. In particular, among the short shutter frames 4.5, the one located on the door pocket 6 side is generally called the closing frame, and the short frame 4 on the door stop side is attached to the end of the lower shutter frame 8. Furthermore, after installing the shutter upper frame 7, the short frame 5 for the parting frame is fixed to the other end of the shutter lower frame 8, and each of the short frames 4, 5 is provided on the outer surface of the sash formwork 9. It has an abbreviated shape and includes a fastening piece a that is superimposed on the mounting piece 10 to the frame 3, and a protruding piece that extends from the end of the fastening piece a toward the outdoor side. When installing such short shutter frames 4 and 5, a waterproof seal 13 is pasted on the lower end of the protruding piece and the contact surface of the lower shutter frame.
A groove 11 is provided at the joint with the lower frame of the shutter and opens toward the indoor side at the base end of the protruding piece.
1 is attached to the mounting piece 1 of the sash formwork 9.
By crimping them to 0, waterproofing is attempted between the short shutter frames 4, 5 and the lower shutter frame 8, as well as between the short shutter frames 4, 5 and the sash forms 9, 9.

However, as shown in FIG. 4, between the tight material 12 and the waterproof seal 13, which correspond to a part of the corner of the L-shaped storm door short frame, there is a concave groove support piece 14 connected to the indoor end of the protruding piece. exists, and the groove support piece 14 and the vertical frame mounting piece 10
Since the gap A cannot maintain watertightness at all, rainwater sprayed onto the short frames 4 and 5 enters the gap A, and the rainwater flows down to the back side of the bottom frame A. It can seep in and corrode the building frame 3 or cause stains on the inside of the room.

This invention was developed with the aim of completely eliminating the intrusion of rainwater from a part of the corner of such an L-shaped storm door short frame and preventing corrosion and staining of the building frame, as shown in Figure 5. As shown, at the lower ends of the L-shaped shutter short frames 4 and 5, there is a section extending from the contacting surface of the protruding piece A to the facing surface of the shutter short frame, including a part of the corner. A waterproof seal 13a is pasted and interposed continuously from between the short shutter frames 4, 5 and the lower shutter frame 8 to between the short shutter frames 4, 5 and the vertical frame mounting piece 10. This is what I did.

The upper edge opening of the waterproof seal 13a has a downward slope from the side end of the fastening piece a to a part of the corner of the L-shaped shutter short frame 4, 5, and has a protrusion from the part of the corner. The shutter has a downward slope toward the outdoor side, so that rainwater that enters and flows down between the bag frame fixing piece a and the sash frame mounting piece 10 is guided onto the bottom frame 8 of the shutter. It has become.

This waterproof seal 13a ensures that some of the corners of the shutter frames 4 and 5 are kept in a wet state, and for the shutter frames 4 and 5, which have a groove 11 at the indoor end of the protruding piece, Since the lower part of the space between the concave groove support piece 14 located at a part of the corner and the sash vertical frame mounting piece 10 is held watertight,
Even if the rainwater that blows onto the shutter short frames 4 and 5 enters the gap A above them and flows down, the waterproof seal 13a prevents the rainwater from flowing further down.
It flows out onto the shutter lower frame 8 along the downwardly sloped slope, and exhibits the effect of reliably preventing rainwater from entering the inner side of the shutter lower frame.

This effect of preventing rainwater intrusion can be similarly obtained with a vertical frame that does not have the tight material 12.

As shown in FIG. 6, if a waterproof seal 15 is interposed between the upper mounting piece 1 of the shutter lower frame 8, the sash lower frame mounting piece 2, and the sash vertical frame mounting piece 10, and the waterproof seal 15 is interposed and brought into close contact with the upper mounting piece 1 of the lower shutter frame 8, Prevents rainwater that blows from between the upper mounting piece 1 of the frame 8 and the lower sash frame mounting piece 2 from entering the back side of the lower sash frame A,
It has the effect of preventing corrosion and staining of building frames.
